38095775 | Anatomical changes in resection cavity during brain radiotherapy. | Brain tumors are in general treated with a maximal safe resection followed by radiotherapy of remaining tumor including the resection cavity (RC) and chemotherapy. Anatomical changes of the RC during radiotherapy can have impact on the coverage of the target volume. The aim of the current study was to quantify the potential changes of the RC and to identify risk factors for RC changes. |
38095772 | Pre- and Post-surgical Prevalence of Thiamine Deficiency in Patients Undergoing Bariatric Surgery: a Systematic Review and Meta-analysis. | Thiamine deficiency is a life-threatening nutritional abnormality observed in the patients with obesity and following bariatric surgery. The aim of the present study is to determine the prevalence of thiamine deficiency prior to and after bariatric procedures. PubMed, Web of Science, Google scholar, CENTRAL, ProQuest, and Scopus were searched to retrieve relevant studies containing data on thiamine deficiency in patients with obesity who underwent bariatric surgery. A proportional meta-analysis approach was used to pool the prevalence of thiamine deficiency prior and after surgery. Our comprehensive literature search retrieved 41 studies with relevant data. The pooled prevalence of thiamine deficiency was 7% (95% CI: 4-12%) at baseline. We observed that 19% (95% CI: 0-68%), 9% (95% CI: 3-17%), and 6% (95% CI: 3-9%) of patients had developed thiamine deficiency at 3 months, 6 months, and 1 year after surgery, respectively. We also report that the prevalence of thiamine deficiency in pregnant women who had history of bariatric surgery. The rate was highest in the first trimester (12%) compared to that in the second (8%) and third (10%) trimesters. The baseline prevalence is 7% for thiamine deficiency in bariatric surgery candidates. The prevalence rate of thiamin deficiency increased to 19% and 9% 3 and 6 months after surgery; however, the rate decreased to 6% 1 year after surgery. Due to the higher prevalence of thiamine deficiency in the early post-operative phase, close monitoring during this period is recommended. A similar strategy should be implemented for pregnant women with history of bariatric surgery in their first trimester. |

38095776 | General anesthesia for cesarean section in a pregnant woman with systemic vascular malformation: a case report. | Vascular malformations are composed of morphologically abnormal vascular tissue, and when located in the head and neck region, they can make it difficult to secure the airway during general anesthesia. |
38095777 | Epigallocatechin Gallate Modulates Microglia Phenotype to Suppress Pro-inflammatory Signalling Cues and Inhibit Phagocytosis. | Microglia are crucial players in the pathogenesis of late-onset Alzheimer's disease (AD), with evidence for both deleterious and beneficial effects. Identifying interventions to modulate microglial responsiveness, promote amyloid β (Aβ) clearance, disrupt plaque formation, or dampen excessive inflammation has therapeutic potential. Bioavailable flavonoids, such as the flavan 3-ols, are of interest due to their antioxidant, metal chelating, signalling, and anti-inflammatory potential. Primary microglia were treated with a series of structurally related flavanol 3-ols to assess effects on phagocytosis, cytokine release, and transcriptional responses by RNA sequencing. Data indicated that the extent of hydroxylation and the presence of the galloyl moiety were strong determinants of flavan 3-ol activity. Epigallocatechin gallate (EGCG) was the most effective flavan-3-ol tested and strongly inhibited phagocytosis of Aβ independent of any metal chelating properties, suggesting a more direct modulation of microglia responsiveness. EGCG was broadly anti-inflammatory, reducing cytokine release and downregulating transcription, particularly of components of the microglia extracellular matrix such as MMP3 and SerpinB2. Collectively, this brings new insight into the actions of flavonoids on microglial responsiveness with potential implications for the therapeutic use of EGCG and structurally related flavanol-3-ols in AD. |

38095768 | PriA is involved in Pleurotus ostreatus development and defense against Pseudomonas tolaasii. | Pleurotus ostreatus is a crucial commercial mushroom widely cultivated for diverse uses. Scientists have worked on breeding disease-resistant and high-yielding varieties to secure food supply. Studies on the molecular genetic mechanism of growth and development can provide valuable information to facilitate crop breeding programs by genetic engineering. Aegerolysins are pore-forming proteins widely distributed in both prokaryotes and eukaryotes, which are reported to have haemolytic activity and be involved in the early stages of fructification. The present study aimed to explore biological function of a differential expressed aegerolysin gene PriA in P. ostreatus. The expression level of PriA gene was higher in primordium and fruiting body than that in mycelium. The PriA expression in overexpression (OE) and RNAi interference (RNAi) strains was detected by qRT-PCR. The RNAi strains grew at slightly slower rates and advanced producing yellow pigments than the wild type, while OE strains showed no prominent phenotypic characteristics. Furthermore, Pseudomonas tolaasii infection assays showed that the PriA OE strains could enhance mycelia and caps resistance to P. tolaasii. These data demonstrate PriA from P. ostreatus play an essential role in mycelial development and increase antagonism against P. tolaasii. Our study provides some reference information on interactions between edible fungi and pathogenic bacteria and offers a new resistance-conferring gene for breeding. |

38095774 | Preoperative assessment of eloquence in neurosurgery: a systematic review. | Tumor location and eloquence are two crucial preoperative factors when deciding on the optimal treatment choice in glioma management. Consensus is currently lacking regarding the preoperative assessment and definition of eloquent areas. This systematic review aims to evaluate the existing definitions and assessment methods of eloquent areas that are used in current clinical practice. |
38095779 | Treatment of Non-Small Cell Lung Cancer with Atypical EGFR Mutations. | EGFR tyrosine kinase inhibitors (TKI) should always be considered when treating advanced/metastatic non-small cell lung cancer (NSCLC) with atypical EGFR mutations. The first choice of TKI depends on the specific mutation(s) present and its effect on structure and function of the EGFR protein. Afatinib is the only EGFR TKI currently FDA approved for atypical EGFR mutations and has the strongest data to support its use in PACC mutations, a subgroup of atypical EGFR mutations which includes G719X and S7681. Dacomitinib may also be an option for these mutations given similar efficacy to afatinib. In contrast, for classical-like mutations such as L861Q, osimertinib should be considered the first choice given that their behavior mimics that of the classical mutations exon 19 deletion and L858R. Osimertinib should also be utilized in the setting of a concurrent T790M mutation. Superior CNS penetrance and well managed toxicity profile may also be reasons to consider osimertinib. Given that the choice of TKI may depend on the specific mutation, it is crucial that every patient diagnosed with NSCLC undergo comprehensive sequencing to identify these mutations. |
38095783 | Tuberculosis Preventive Treatment. | Some individuals exposed to Mycobacterium tuberculosis develop a latent infection and remain at a lifelong risk of developing tuberculosis (TB) disease, a state called as TB infection (TBI). TB preventive treatment (TPT) aims to treat TBI and prevent progression to active TB in an exposed or infected person. Currently, it is not possible to confirm TBI microbiologically, but can be identified indirectly by means of immune-based tests [Tuberculin skin test (TST), interferon-gamma release assays (IGRAs)]. It is crucial to rule out active TB before initiating TPT. TPT regimens have evolved with time. The most widely used regimen is 6 mo of daily Isoniazid (INH) (6H). Another regime in pipeline for persons >2 y, but not yet widely available, is 3HP (3 mo of weekly Isoniazid and Rifapentine). TPT to contacts of drug resistant TB (DR-TB) patients needs to be tailored depending on the resistance pattern in the index case, and relies on a bacteriological confirmation of the same. Individuals receiving TPT should be closely monitored for emergence of any signs or symptoms suggestive of active TB disease while on TPT. |
38095786 | IoT-based COVID-19 detection using recalling-enhanced recurrent neural network optimized with golden eagle optimization algorithm. | New potential for healthcare has been made possible by the development of the Internet of Medical Things (IoMT) with deep learning. This is applied for a broad range of applications. Normal medical devices together with sensors can gather important data when connected to the Internet, and deep learning uses this data to reveal symptoms and patterns and activate remote care. In recent years, the COVID-19 pandemic caused more mortality. Millions of people have been affected by this virus, and the number of infections is continually rising daily. To detect COVID-19, researchers attempt to utilize medical imaging and deep learning-based methods. Several methodologies were suggested utilizing chest X-ray (CXR) images for COVID-19 diagnosis. But these methodologies do not provide satisfactory accuracy. To overcome these drawbacks, a recalling-enhanced recurrent neural network optimized with golden eagle optimization algorithm (RERNN-GEO) is proposed in this paper. The intention of this work is to provide IoT-based deep learning method for the premature identification of COVID-19. This paradigm can be able to ease the workload of radiologists and medical specialists and also help with pandemic control. RERNN-GEO is a deep learning-based method; this is utilized in chest X-ray (CXR) images for COVID-19 diagnosis. Here, the Gray-Level Co-Occurrence Matrix (GLCM) window adaptive algorithm is used for extracting features to enable accurate diagnosis. By utilizing this algorithm, the proposed method attains better accuracy (33.84%, 28.93%, and 33.03%) and lower execution time (11.06%, 33.26%, and 23.33%) compared with the existing methods. This method can be capable of helping the clinician/radiologist to validate the initial assessment related to COVID-19. |
38095784 | Association of radiotherapy for prostate cancer and second primary colorectal cancer: a US population-based analysis. | Radiotherapy (RT) is a common treatment for prostate cancer, yet the risk of second primary colorectal cancer (SPCRC) in patients with prostate cancer undergoing RT has not been adequately studied. |
38095778 | Non-Surgical Therapeutic Strategies for Non-Melanoma Skin Cancers. | Non-melanoma skin cancer (NMSC) is a globally prevalent skin disease, with basal cell carcinoma and squamous cell carcinoma accounting for 99% of NMSC cases. While surgical excision is the most common approach, numerous non-surgical therapies have rapidly advanced in recent years. In cases of low-risk NMSC, alongside surgical excision, priority should be given to physical therapy and photodynamic therapy. Physical therapy modalities, exemplified by electrodessication and curettage, emerge as safe and efficacious alternatives. In juxtaposition, photodynamic therapy, albeit relatively more costly, assumes preference for patients exhibiting heightened cosmetic concerns owing to the scarring risks inherent to physical therapy and surgical excision. Notably, the combination of curettage and photodynamic therapy has exhibited remarkable efficacy in the treatment of nodular basal cell carcinoma. Additionally, for elderly patients who may be intolerant to stimulation, modified photodynamic therapy offers an almost painless option. When surgery is unavoidable, photodynamic therapy can be a valuable adjunct, allowing for a more conservative surgical approach, either before or after the procedure. Radiotherapy holds a prominent role in comprehensive treatment strategies, especially for patients ineligible for surgical intervention or those with lesions precluding further surgical measures. In cases of NMSC exhibiting perineural invasion or lymphovascular involvement, adjunctive radiotherapy is advised; however, potential adverse effects necessitate careful consideration. For advanced NMSC cases where surgery and physical therapy fall short, immunotherapy provide viable solutions. Systemic therapy employing Hedgehog pathway inhibitors can be considered for patients with distant metastatic basal cell carcinoma, despite its low incidence, or individuals with locally advanced lesions who are not surgical candidates, or those encountering recurrences after resection and radiotherapy. However, close monitoring of disease progression and adverse reactions is crucial. In this evolving landscape of NMSC treatment, personalized and multidisciplinary approaches are key, ensuring optimal outcomes while prioritizing patient safety and satisfaction. |
38095789 | Remediation of 2,4-dichlorophenol-contaminated soil by electrokinetic delivery of persulfate technology. | 2,4-Dichlorophenol (2,4-DCP) is difficult to degrade rapidly in the environment due to its stable chemical properties, so it was easy to lead to serious chlorophenol pollution in soil. Consequently, a remediation method which is efficient, safe, and economical is required. In this study, electrokinetic (EK) remediation was used to transfer sodium persulfate (Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub>) into soil to degrade 2,4-DCP, and the effect of several factors (including the addition location of Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub>, applied voltage, and running time) on the remediation efficiency was explored. The concentration of Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub>, residual efficiency of 2,4-DCP and distribution characteristics of pH, and electrical conductivity were analyzed. The results showed that the cathode was the optimal position to add Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub>. Under this condition, Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub> was uniformly distributed in the whole soil column through electromigration. The optimal removal efficiency of 2,4-DCP in soil by adding Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub> was approximately 26% when the voltage gradient was 1.0 V/cm and the operating time was 9 days, which was mainly due to the degradation of S<sub>2</sub>O<sub>8</sub><sup>2-</sup>. |
38095788 | NMR based Serum metabolomics revealed metabolic signatures associated with oxidative stress and mitochondrial damage in brain stroke. | Brain stroke (BS, also known as a cerebrovascular accident), represents a serious global health crisis. It has been a leading cause of permanent disability and unfortunately, frequent fatalities due to lack of timely medical intervention. While progress has been made in prevention and management, the complexities and consequences of stroke continue to pose significant challenges, especially, its impact on patient's quality of life and independence. During stroke, there is a substantial decrease in oxygen supply to the brain leading to alteration of cellular metabolic pathways, including those involved in mitochondrial-damage, leading to mitochondrial-dysfunction. The present proof-of-the-concept metabolomics study has been performed to gain insights into the metabolic pathways altered following a brain stroke and discover new potential targets for timely interventions to mitigate the effects of cellular and mitochondrial damage in BS. The serum metabolic profiles of 108 BS-patients were measured using 800 MHz NMR spectroscopy and compared with 60 age and sex matched normal control (NC) subjects. Compared to NC, the serum levels of glutamate, TCA-cycle intermediates (such as citrate, succinate, etc.), and membrane metabolites (betaine, choline, etc.) were found to be decreased BS patients, whereas those of methionine, mannose, mannitol, phenylalanine, urea, creatine and organic acids (such as 3-hydroxybutyrate and acetone) were found to be elevated in BS patients. These metabolic changes hinted towards hypoxia mediated mitochondrial dysfunction in BS-patients. Further, the area under receiver operating characteristic curve (ROC) values for five metabolic features (methionine, mannitol, phenylalanine, mannose and urea) found to be more than 0.9 suggesting their high sensitivity and specificity for differentiating BS from NC subjects. |
38095764 | DNA repair in tumor radioresistance: insights from fruit flies genetics. | Radiation therapy (RT) is a key anti-cancer treatment that involves using ionizing radiation to kill tumor cells. However, this therapy can lead to short- and long-term adverse effects due to radiation exposure of surrounding normal tissue. The type of DNA damage inflicted by radiation therapy determines its effectiveness. High levels of genotoxic damage can lead to cell cycle arrest, senescence, and cell death, but many tumors can cope with this damage by activating protective mechanisms. Intrinsic and acquired radioresistance are major causes of tumor recurrence, and understanding these mechanisms is crucial for cancer therapy. The mechanisms behind radioresistance involve processes like hypoxia response, cell proliferation, DNA repair, apoptosis inhibition, and autophagy. |
38095792 | Adsorption characteristics and mechanisms of Cd(II) from wastewater by modified chicken manure biochar. | Due to the threat to food supply and human health posed by cadmium-contaminated wastewater, a highly effective adsorbent is under necessary development to remove cadmium from wastewater. In this study, four new types of modified biochars with different modifier concentrations were prepared from chicken manure using K<sub>2</sub>FeO<sub>4</sub> as a modifier, and the modified biochar KFBC<sub>1</sub> with the best adsorption effect was obtained through optimal experiments. Various characterization analyses have shown that KFBC<sub>1</sub> has a rough surface structure, abundant pore structure, and a large number of functional groups. Additionally, iron oxides are introduced on the surface of the biochar, which provided a favorable condition for the adsorption of Cd(II) in wastewater. The adsorption performance of Cd(II) on the biochar before and after modification was investigated through batch adsorption experiments. The adsorption kinetic model of KFBC<sub>1</sub> to Cd(II) in solution was in accordance with the quasi-secondary kinetic model, and the adsorption isothermal model was in accordance with the Langmuir model, with a maximum adsorption capacity of 330.06 mg/g, which was 5.15 fold of pristine BC. Meanwhile, the adsorption rate of Cd(II) by KFBC<sub>1</sub> was positively correlated with dosage and pH. Pore adsorption, ion exchange, surface precipitation, interaction with -π electrons, and complexation of oxygen-containing functional groups on the surface were considered as important mechanisms for the removal of Cd(II) by KFBC<sub>1</sub>. According to the results, KFBC<sub>1</sub> is a novel and efficient adsorbent that can be used as a treatment agent for cadmium-contaminated wastewater. |
38095794 | Process-specific volatile organic compounds emission characteristics, environmental impact and health risk assessments of the petrochemical industry in the Beijing-Tianjin-Hebei region. | Volatile organic compounds (VOCs) concentration, source profiles, O<sub>3</sub> and SOA formation, and health risks were investigated in the petrochemical industry in Beijing-Tianjin-Hebei. The results showed that total VOCs concentrations were 547.1-1956.5 μg·m<sup>-3</sup>, and alkanes were the most abundant group in all processes (31.4%-54.6%), followed by alkenes (20.6%-29.2%) and aromatics (10.1%-25.1%). Moreover, ethylene (11.3%), iso-pentane (7.1%), n-hexane (5.1%), benzene (4.9%) and 2,2-dimethylbutae (4.8%) were identified as the top five species released for the whole petrochemical industry. The coefficient of divergence between the source profiles from different processes was 0.49-0.73, indicating that most source profiles must not be similar. Moreover, because of the different raw materials and technologies used, the source profiles in this study are significantly different from those of other regions. The ozone and secondary organic aerosol formation potentials (OFPs and SOAPs) were evaluated, suggesting that ethylene, propylene, 1-butene, m,p-xylene, and 1,3-butadiene should be preferentially controlled to reduce OFPs. That benzene, toluene, ethylbenzene, m,p-xylene, isopropylbenzene, o-ethyltoluene, and 1,3,5-trimethylbenzene should be priority control compounds for SOAPs. Additionally, the total hazard ratio for non-cancer risk ranged from 0.9 to 7.7, and only living area was unlikely to be related to adverse health effects. Cancer risks associated with organic chemicals, rubber synthesis, oil refining, and wastewater collection and treatment have definite risks, whereas other processes have probable risks. This study provides a scientific basis for VOCs emission control and management and guides human health in the petrochemical industry. |
38095791 | Association of flavonoid intake with coronary artery disease risk in the older population based on the National Health and Nutrition Examination Survey. | We investigated the association between flavonoid intake and coronary artery disease (CAD) risk in older adults. Data were extracted from the National Health and Nutrition Examination Survey (age ≥ 70 years; 2007-2010 and 2017-2018; n = 2 417). The total flavonoid and flavonoid subclass intake was calculated using validated food frequency questionnaires. The association between flavonoid intake and CAD risk was examined using generalized linear models with restricted cubic spline models. After multivariate adjustment, anthocyanin intake was positively associated with CAD risk; no significant associations were observed between other flavonoid subcategories and endpoint outcomes. Anthocyanins exhibited a non-linear association with CAD risk, and threshold effect analysis showed an inflection point of 15.8 mg/day for anthocyanins. Per unit increase in anthocyanins, the odds of CAD on the left of the inflection point decreased by 2%, while the odds on the right increased by 35.8%. Excessive flavonoid intake may increase CAD risk in the older population. |
38095785 | Maternal and newborn metabolomic changes associated with urinary polycyclic aromatic hydrocarbon metabolite concentrations at delivery: an untargeted approach. | Prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with adverse human health outcomes. To explore the plausible associations between maternal PAH exposure and maternal/newborn metabolomic outcomes, we conducted a cross-sectional study among 75 pregnant people from Cincinnati, Ohio. |
38095793 | Greening the economy: how culture values shape environmental policies in America and Europe. | This research explores the theory that cultural factors shape how people feel about the environment. Both theoretical and empirical approaches are used in our investigation of this problem. In the theoretical part of the study, we provide a model for transferring cultural practices from one generation to the next. To provide empirical evidence for the existence of this cultural factor in environmental views, we analyze survey data from the European Values Research. Using a comparative method, we use differences caused by migration patterns in Europe and America. According to our research, cultural influences on migrants' ecological beliefs are long-lasting and statistically significant. Variations in migrants' environmental views may be traced back to societal norms that endure in their home countries. We also demonstrate that ecological views are robust in the face of incentives originating from the external environment, demonstrating that migrants' choices in the host nation are not much influenced by the environmental circumstances they were exposed to in their home countries. We uncover fascinating variations in the cultural transfer procedure, and our results hold up under various hypotheses. These findings suggest that, in light of the prevalence of ecological problems requiring community action, it is crucial to formulate policies that consider the factors that led to the development of ecological cultures. |
38095795 | Regional differences in Hg contents in the liver and muscle of the green turtle (Chelonia mydas) from three foraging grounds in Northeast Brazil. | Mercury (Hg) is a highly toxic pollutant that endangers several marine animals, including green sea turtles (Chelonia mydas), particularly in their foraging grounds along Brazilian coastal waters. Environmental Hg levels differ along this extensive littoral, rendering mandatory Hg long-term assessments of the different Hg fate in different sectors of the Brazilian coast. This study quantifies total Hg concentrations in the liver and muscle of green sea turtle populations from three foraging coastal regions in northeastern Brazil and analyzes Hg concentration differences given the locality and size of 61 juvenile individuals sampled. The results showed wide variations in Hg concentrations in the liver (81-3135 ng g<sup>-1</sup>) and muscle (10.1-8569 ng g<sup>-1</sup>). There was no significant correlation between animal size and Hg concentrations. Also, no difference was found among areas, reflecting the opportunistic feeding habit of juveniles of this species. This suggests that, in the case of green turtles, the ontogenetic change of diet plays an important role in influencing Hg concentrations found in this species. |
38095796 | A novel combined system for efficient nitrate removal using a continuous flow electrocoagulation and sand filtration (FECF) reactor: Statistical analysis by Taguchi design. | In this study, a new hybrid bench-scale electrocoagulation-sand filtration (FECF) reactor was developed for purifying nitrate-contaminated samples. Before and after electrochemical treatment, two sand filters were included in this continuous system to facilitate the purification procedure, and the contaminated water flows horizontally through the entire system according to a specific hydraulic gradient within the reactor, resulting in water purification. Significant improvement in treatment performance was observed due to the presence of metal hydroxides in the second filter media that were not fully involved in the electrocoagulation treatment. Energy dispersive X-ray (EDX) analysis was performed to detect metal hydroxide species in the sand media, and the need for filter regeneration was evaluated by monitoring changes in the system flow rate. Moreover, an evaluation of the effects of different factors including operating time, current intensity, initial pH, type of anode and cathode, initial nitrate concentration, hydraulic head level inside the reactor, number of electrodes, and NaCl electrolyte concentration on the performance of nitrate removal was conducted through the Taguchi design. Further, ANOVA analysis verified the accuracy of the predicted model, and the variables were classified based on their relative importance in the FECF process. According to the regression model, 97% of nitrates were removed with Al electrodes as anode and Fe as cathode, 70 min purification time, current intensity of 3 A, 100 mg/l initial nitrate concentration, pH 8, electrolyte concentration of 1 g/l, electrode number of 6, and 1.5 cm head level. |
38095787 | Insights on Three Dimensional Organoid Studies for Stem Cell Therapy in Regenerative Medicine. | Regenerative medicine has developed as a promising discipline that utilizes stem cells to address limitations in traditional therapies, using innovative techniques to restore and repair damaged organs and tissues. One such technique is the generation of three-dimensional (3D) organoids in stem cell therapy. Organoids are 3D constructs that resemble specific organs' structural and functional characteristics and are generated from stem cells or tissue-specific progenitor cells. The use of 3D organoids is advantageous in comparison to traditional two-dimensional (2D) cell culture by bridging the gap between in vivo and in vitro research. This review aims to provide an overview of the advancements made towards regenerative medicine using stem cells to generate organoids, explore the techniques used in generating 3D organoids and their applications and finally elucidate the challenges and future directions in regenerative medicine using 3D organoids. |
38095799 | Efficacy of Atezolizumab Plus Bevacizumab Versus Lenvatinib in Patients with Unresectable Hepatocellular Carcinoma: a Meta-analysis. | Hepatocellular carcinoma is a lethal disease and there has been a debate regarding the first-line treatment of its advanced and unresectable form. Observational studies have explored atezolizumab plus bevacizumab versus lenvatinib, yielding mixed results. This systematic review and meta-analysis aim to compare efficacy and safety of both treatment arms. |
38095801 | Catechol-Isolated Atomically Dispersed Nanocatalysts for Self-Motivated Cocatalytic Tumor Therapy. | Nanocatalytic tumor therapy based on Fenton nanocatalysts has attracted considerable attention because of its therapeutic specificity, enhanced outcomes, and high biocompatibility. Nevertheless, the rate-determining step in Fenton chemistry, which involves the transition of a high-valence metallic center (FeIII) to a Fenton-active low-valence metallic center (FeII), has hindered advances in nanocatalyst-based therapeutics. In this study, we constructed mesoporous single iron atomic nanocatalysts (mSAFe NCs) by employing catechols from dopamine to coordinate and isolate single iron atoms. The catechols also serve as reductive ligands, generating a field-effect-based cocatalytic system that instantly reduces FeIII species to FeII species within the mSAFe NCs. This self-motivated cocatalytic strategy enabled by mSAFe NCs accelerates the kinetics of the Fenton catalytic reaction, resulting in remarkable performance for nanocatalytic tumor therapy both in vitro and in vivo. |
38095798 | Detection of IgG Anti-Giardia duodenalis Antibodies in Sera by Indirect Immunofluorescence and Western Blotting Assays. | Serological assays are alternative laboratory tools for the diagnosis of parasitic infections. The aim of this work was to evaluate the performance of the indirect fluorescent antibody test (IFAT) and Western blotting (WB) for the detection of IgG anti-Giardia antibodies in human sera. |
38095800 | Effects of enhanced adsorption haemofiltration versus haemoadsorption in severe, refractory septic shock with high levels of endotoxemia: the ENDoX bicentric, randomized, controlled trial. | Endotoxin adsorption is a promising but controversial therapy in severe, refractory septic shock and conflicting results exist on the effective capacity of available devices to reduce circulating endotoxin and inflammatory cytokine levels. |
38095797 | The feasibility of a multidimensional intervention in lymphoma survivors with chronic fatigue. | Chronic fatigue (CF) affects 25-30% of lymphoma survivors, but interventions designed to reduce fatigue are lacking. The main aim of this study was to test the feasibility of a multidimensional intervention study in lymphoma survivors with CF. Secondary aims were to describe individual changes in fatigue, quality of life (QoL) and physical performance from pre (T0) to post (T1) intervention. |
38095790 | Occurrence, ecological risk, and advanced removal methods of herbicides in waters: a timely review. | Coastal pollution caused by the importation of agricultural herbicides is one of the main environmental problems that directly affect the coastal primary productivity and even the safety of human seafood. It is urgent to evaluate the ecological risk objectively and explore feasible removal strategies. However, existing studies focus on the runoff distribution and risk assessment of specific herbicides in specific areas, and compared with soil environment, there are few studies on remediation methods for water environment. Therefore, we systematically reviewed the current situation of herbicide pollution in global coastal waters and the dose-response relationships of various herbicides on phytoplankton and higher trophic organisms from the perspective of ecological risks. In addition, we believe that compared with the traditional single physical and chemical remediation methods, biological remediation and its combined technology are the most promising methods for herbicide pollution remediation currently. Therefore, we focus on the application prospects, challenges, and management strategies of new bioremediation systems related to biology, such as constructed wetlands, membrane bioreactor processes, and microbial co-metabolism, in order to provide more advanced methods for reducing herbicide pollution in the water environment. |
38095805 | Machine Learning in Invasive and Noninvasive Coronary Angiography. | The objective of this review is to shed light on the transformative potential of machine learning (ML) in coronary angiography. We aim to understand existing developments in using ML for coronary angiography and discuss broader implications for the future of coronary angiography and cardiovascular medicine. |
38095807 | Morphological variations on vital systems in a conjoined twin. | Conjoined twins (CTs), popularly referred to as Siamese twins, are a rare anomaly due to monochorionic and monoamniotic twin pregnancies. Dicephalus dibrachius dipus, a type of parapagus conjoined twin which is characterized by possessing two arms, two legs, a single trunk and two heads, epidemiologically, is an even rarer occurrence of CTs. In this article, a rare, well-preserved anatomical specimen of a dicephalus dibrachius dipus conjoined twin is presented. This study was conducted in a specimen which is part of the collection of the Embryology Museum of the institution by donation and approved by the Research Ethics Committee (REC). The female conjoined twins were born at full-term by cesarean section in the 1970s and died hours after birth. A thorough anatomical description was made through observational analysis, computed tomography and 3D reconstructed images. Major abnormalities were observed in the cardiovascular, respiratory and digestive systems. The internal anatomy exhibited a heart with three atria, two ventricles, two aortic arches, two pulmonary arteries, one innominate venous trunk and a respiratory system with two tracheas and four lungs. No other report was similar to our three atria heart description. This article provides a thorough anatomical description of all systems, which is valuable information for further studies on CTs. |

The study objective was to quantify underestimation of pertussis cases in adults aged ≥ 50 years in five Latin American countries (Argentina, Brazil, Chile, Mexico, Peru). |
38095803 | Inhibition of TLR4, NF-κB, and INOS pathways mediates ameliorative effect of syringic acid in experimental ulcerative colitis in rats. | Numerous therapeutics and pharmacological properties have been reported in syringic acid (SA). In this study, we aimed to evaluate effect of SA in ulcerative colitis (UC) in rats considering effect on TLR4, NF-κB, and INOS pathways. |
38095802 | Gut microbiota in relationship to diabetes mellitus and its late complications with a focus on diabetic foot syndrome: A review. | Diabetes mellitus is a chronic disease affecting glucose metabolism. The pathophysiological reactions underpinning the disease can lead to the development of late diabetes complications. The gut microbiota plays important roles in weight regulation and the maintenance of a healthy digestive system. Obesity, diabetes mellitus, diabetic retinopathy, diabetic nephropathy and diabetic neuropathy are all associated with a microbial imbalance in the gut. Modern technical equipment and advanced diagnostic procedures, including xmolecular methods, are commonly used to detect both quantitative and qualitative changes in the gut microbiota. This review summarises collective knowledge on the role of the gut microbiota in both types of diabetes mellitus and their late complications, with a particular focus on diabetic foot syndrome. |

38095806 | Fertility issues in hypopituitarism. | Women with hypopituitarism have lower fertility rates and worse pregnancy outcomes than women with normal pituitary function. These disparities exist despite the use of assisted reproductive technologies and hormone replacement. In women with hypogonadotropic hypogonadism, administration of exogenous gonadotropins can be used to successfully induce ovulation. Growth hormone replacement in the setting of growth hormone deficiency has been suggested to potentiate reproductive function, but its routine use in hypopituitary women remains unclear and warrants further study. In this review, we will discuss the clinical approach to fertility in a woman with hypopituitarism. |
38095815 | Factors Associated with Suicide Risk Behavior Outcomes Among Black High School Adolescents. | There is an urgent need for youth suicide research, particularly among Black adolescents, for whom there have been significant increases over time. This study examines associations between eight covariates and suicide ideation, planning, and attempts among a national sample of Black high school adolescents to inform prevention efforts. Utilizing the 2019 National Youth Risk Behavior Survey data, a sample of N = 6225 Black high school participants was analyzed. A weighted classification tree and network analysis were used to visualize data features, and weighted multinomial ordered logistic regression analyses with multiple imputation pooled using Rubin's rules were performed. Suicide ideation rates of 16% were found in the sample and a higher reported rate of suicide attempts (56%) for those who have reported both ideation and planning. Interpersonal and multilevel factors, including suffering from bullying/cyberbullying, carrying a weapon, or being a sexual minority, were significantly associated with all three suicide behaviors. Findings support an interrelated and multilevel nature of suicide risk factors. Prevention programs for Black adolescents should consider the intersectionality of identities and experiences. |
38095813 | Classification of fetal and adult red blood cells based on hydrodynamic deformation and deep video recognition. | Flow based deformation cytometry has shown potential for cell classification. We demonstrate the principle with an injection moulded microfluidic chip from which we capture videos of adult and fetal red blood cells, as they are being deformed in a microfluidic chip. Using a deep neural network - SlowFast - that takes the temporal behavior into account, we are able to discriminate between the cells with high accuracy. The accuracy was larger for adult blood cells than for fetal blood cells. However, no significant difference was observed between donors of the two types. |
38095809 | Lab-on-chip technologies for space research - current trends and prospects. | The in-depth analysis concerning application of microfluidic instruments for space biology research is presented. The article focuses on recently investigated key scientific fields, i.e., lab-on-chips applied to the biomedical studies performed in the (1) International Space Station and (2) CubeSat nanosatellites. The paper presents also the lab-on-chip devices that were fabricated with a view to future space biology research and to those that to date have been solely been tested under Earth laboratory conditions and/or simulated microgravity environments. NASA and ESA conceptual mission plans for future are also mentioned, concerning for instance "tissue chips" and the ESA-SPHEROIDS campaign. The paper ends with final conclusions and future perspectives regarding lab-on-chip application in the space biology sector and its impact on novel biomedical and pharmaceutical strategies. |

38095814 | The Impact of a Student-Led Health Education Clinic on the Health Literacy and Behaviors of a Rural Community in the State of Pennsylvania, USA. | Rural populations experience a number of disparities that place them at increased risk of morbidity and mortality related to chronic disease, including lower health literacy and greater distance to medical care. Community-based free healthcare education can offer targeted preventive care to these vulnerable populations; however, limited quantitative research exists measuring their impact, specifically on health literacy and likelihood for behavior change. To investigate this, a student-led health education clinic was held in January 2023 in the rural community of Lykens, Pennsylvania by the Student-run and Collaborative Outreach Program for Health Equity (SCOPE). Fifty-five pre- and post-clinic surveys using Likert-style questions measured the knowledge and likelihood of behavioral change for several preventive health topics, including hypertension, diabetes mellitus, cancer screenings, childhood vaccinations, skin cancer, mental health, addiction, and nutrition. From pre- to post-clinic, there was a significant increase in knowledge of hypertension (p = 0.023) and diabetes (p = 0.014), likelihood of attending cancer screenings (p = 0.038), and confidence in identifying cancerous moles (p = < 0.001). There was a non-significant increase in understanding of mental health and nutrition, and no change in understanding of addiction or childhood vaccinations. It is likely that the level of interaction in education provided and relevance of information to participants contributed to effective uptake of information. The results demonstrate an immediate impact on health literacy and likelihood of behavioral change for several important preventive health topics, and advocate for the use of student-run healthcare interventions in addressing the prevalence of chronic disease in rural communities. |
38095816 | Photostimulation of lymphatic clearance of β-amyloid from mouse brain: a new strategy for the therapy of Alzheimer's disease. | Alzheimer's disease (AD) is an age-related neurodegenerative disorder that poses a significant burden on socio-economic and healthcare systems worldwide. However, the currently available therapy of AD is limited, and new strategies are needed to enhance the clearance of β-amyloid (Aβ) protein and improve cognitive function. Photobiomodulation (PBM) is a non-invasive and effective therapeutic method that has shown promise in treating various brain diseases. Here, we demonstrate that 1267-nm PBM significantly alleviates cognitive decline in the 5xFAD mouse model of AD and is safe as it does not induce a significant increase in cortical temperature. Moreover, with the combination of 3D tissue optical clearing imaging and automatic brain region segmentation, we show that PBM-mediated reductions of Aβ plaques in different subregions of prefrontal cortex and the hippocampus are different. The PBM-induced lymphatic clearance of Aβ from the brain is associated with improvement of memory and cognitive functions in 5xFAD mice. Our results suggest that the modulation of meningeal lymphatic vessels (MLVs) should play an important role in promoting Aβ clearance. Collectively, this pilot study demonstrates that PBM can safely accelerate lymphatic clearance of Aβ from the brain of 5xFAD mice, promoting improvement of neurocognitive status of AD animals suggesting that PBM can be an effective and bedside therapy for AD. |

38095818 | Effect of lateral hinge fractures for bone union and clinical outcomes following opening-wedge distal tibial tubercle osteotomy in comparison with opening-wedge high tibial osteotomy. | Although the effects of lateral hinge fractures (LHF) on bone union and clinical outcomes after opening-wedge high tibial osteotomy (OWHTO) have been established, the effects of LHF after opening-wedge distal tibial tubercle osteotomy (OWDTO) are unclear. We hypothesised that LHF after OWDTO would be associated with delayed bone union and result in poorer clinical outcomes than expected for LHF after OWHTO. |
38095821 | Photosensitised versus conventional infection control: the local fight continues. | The worsening problem of antimicrobial drug resistance requires a nuanced approach. Since the conventional drug pipeline is unlikely to be sufficient to avoid massive increases in mortality by the mid-twenty-first century, other methods of antisepsis will be required. These might be used either in place of (allowing conservation) or together with conventional agents. Of such approaches, locally applied protocols involving photo-antimicrobials suggest themselves, particularly as early intervention, e.g. in bacterial tonsillitis, would be curative without recourse to conventional drugs, and would thus prevent the development of more serious diseases such as pneumonia or meningitis. However, given the pharmaceutical industry's lack of investment in such approaches, support would be required from other areas of bioscience, such as the biomed or biotech sectors. |

38095823 | India's Quantum Move: From Budget Allocation, Action and Future Challenges. | Major countries like the USA, European Union, UK, Japan, Canada, Australia, Singapore, and China have taken significant initiatives to develop quantum computation infrastructure. India has also taken several steps to join the quantum computation family. The Indian government has taken several initiatives to build the nation's infrastructure on quantum computation and participate in the global quantum landscape. The Indian government has created a roadmap in this direction. The significant steps are: firstly, noteworthy budget allocation (1.12 billion USD in 2020 and 734 million USD for the National Quantum Mission in 2023); secondly, 21 quantum hubs are being developed throughout the country; thirdly, 4 quantum research parks have been created and finally, Department of Science and Technology (DST) has initiated QuEST (Quantum Enabled Science and Technology) programme during 2017-18. The article also discusses other effective strategies and moves by the Indian government, like different ambitious national missions on quantum science and technology to create the country's ecosystem. In that direction, the article addresses the opportunities and challenges of quantum science and technology for India. However, the Indian government should encourage quantum computation research more for the country's development. Finally, the information provided here depicts an overall view of India's quantum computation landscape. |
38095822 | Lecanemab: More Questions Than Answers! | The approval of lecanemab by the US Food and Drug Administration has been touted as a defining moment in the treatment of Alzheimer's disease. Lecanemab, an anti-amyloid beta monoclonal antibody, is the first Alzheimer's disease drug targeting amyloid beta that has shown statistically significant cognitive benefits in phase III trials. However, there have been many questions raised over the clinical relevance of the otherwise minimal cognitive improvements. Furthermore, its rapid approval has been mired in controversy, in addition to the reports of adverse events such as amyloid-related imaging abnormalities and several deaths of participants in the lecanemab trials. Here, we analyze the evidence supporting lecanemab as an amyloid beta therapy and also discuss the concerns raised about its efficacy and safety. |
38095827 | Ethics, Abortion Access, and Emergency Care Post-Dobbs: The Gray Areas. | Clinical management of emergency pregnancy care, such as ectopic pregnancy or heavy bleeding with pregnancy of unknown location, includes upholding legal and ethical standards. For health care providers unwilling to provide evidence-based life-saving abortion care due to personal beliefs, clear guidance dictates disclosure of these limitations to the patient and colleagues, followed by immediate referral for appropriate care. However, this decision-making pathway may not be engaged due to a variety of factors: providers' beliefs preclude adherence to referral responsibilities, political discourse confuses patients as to their options and rights, and a constantly changing state and national legal landscape leads providers to question their ability to practice to their full scope of clinical care. Although this disruption of evidence-based standard of care existed pre-Dobbs, the moral disorder is now heightened. This Clinical Rounds highlights a patient vignette describing the risks of abortion restrictions for patients and providers alike, particularly when an individual provider's concerns for violating institutional guidelines sets a precedent for nursing response and forecloses on collaborative input or ethics consultation. The history of physician-only abortion exceptionalism and exclusion of nurses and midwives despite a significant history of nurses and midwives in abortion care grounds an argument for focusing on the impact of unethical and substandard care on the interprofessional care team leading to moral distress and negative patient outcomes. Patient-centered models of care, such as frameworks common in nursing and midwifery, offer opportunities to consider how all providers practicing to their full scope in interprofessional and collaborative ways, such as in emergency rooms and labor departments, might mitigate obstructions to abortion care that risk pregnant people's lives. |
38095826 | Duodenal microbiome in chronic kidney disease. | The intestinal microbiome is involved in the pathogenesis of chronic kidney disease (CKD). Despite its importance, the microbiome of the small intestinal mucosa has been little studied due to sampling difficulties, and previous studies have mainly focused on fecal sources for microbiome studies. We aimed to characterize the small intestinal microbiome of CKD patients by studying the microbiome collected from duodenal and fecal samples of CKD patients and healthy controls. |
38095819 | Time spent above optimal cerebral perfusion pressure is not associated with failure to improve in outcome in traumatic brain injury. | Optimal cerebral perfusion pressure (CPPopt) has emerged as a promising personalized medicine approach to the management of moderate-to-severe traumatic brain injury (TBI). Though literature demonstrating its association with poor outcomes exists, there is yet to be work done on its association with outcome transition due to a lack of serial outcome data analysis. In this study we investigate the association between various metrics of CPPopt and failure to improve in outcome over time. |
38095825 | Structural Inequities, Syndemics, and Resilience: The Critical Role of Social Support in Overcoming Barriers and Empowering Engagement in HIV Care for Young Black Sexual-Minority Men in the US South. | Young Black sexual minority men (YBSMM) living in the US South are among those most disproportionately impacted by HIV in the USA. This health inequity is, in part, due to lower rates of sustained engagement in the HIV care continuum, resulting in a lower prevalence of viral suppression and higher overall community-level viral load. Social, structural, and economic inequities have previously been linked with poorer HIV care engagement among YBSMM. HIV-related social support, individual-level resilience, and healthcare empowerment have been shown to be independently associated with improved HIV care engagement. The current study sought to assess the relative contribution of individual, structural, and economic factors on engagement in HIV care and to elucidate the potentially mediating role of healthcare empowerment. Data from 224 YBSMM with HIV in the US South indicated that greater levels of socioeconomic distress, intimate partner violence, and depressive symptoms were associated with lower levels of engagement in HIV care, while greater levels of individual-level resilience and healthcare empowerment were associated with higher levels of HIV care engagement. Importantly, healthcare empowerment mediated the association between resilience and engagement in HIV care and the association between social support and engagement in HIV care. Findings emphasize the critical role that HIV-related social support plays in fostering resilience and overcoming syndemic factors to promote empowerment and engagement in HIV care for YBSMM in the USA. |
38095830 | Patient experiences in receiving telegenetics care for inherited cardiovascular diseases. | Telegenetics played an important role in providing genetic services to patients during the COVID-19 pandemic. In particular, at our institution, it enabled us to expand our genetic counseling and testing services to non-local family members of patients outside of our prior catchment area. However, as telegenetics continues to be utilized even as social distancing is no longer required, further information is needed regarding the impact of this modality on patient experience within cardiogenetics. This study qualitatively explored the experiences of 12 genotype positive individuals who underwent genetic counseling and testing via telegenetics during the first 22 months of the COVID-19 pandemic and compared the experiences of local vs. non-local patients. Both local and non-local participants discussed similar benefits and drawbacks to the use of technology in telegenetics and overall found the use of telegenetics and at-home genetic testing to be convenient. Both groups also noted having to make changes in their daily lives and future planning as a consequence of the positive genetic testing results. However, access to follow-up care differed between local and non-local participants, with more local participants having scheduled and attended appointments with the appropriate medical providers compared to non-local participants. Supplying non-local patients access to remote cardiogenetic testing may therefore require careful consideration in how to ensure proper follow-up care for genotype positive patients and may necessitate the involvement of national professional or patient-centered organizations to help streamline the referral process. |
38095829 | A New Eyeless Species of Micranops Cameron 1913 from Bolivia (Coleoptera: Staphylinidae: Paederinae). | This work adds a new eyeless species of the genus Micranops Cameron, 1913 (Staphylinidae, Paederinae, Scopaeina) to the endogean Coleoptera of the Bolivian fauna. The loss of eyes is usually associated with adaptations to subterranean habitats, although M. bolivianus Guzman & Żyła sp. nov. was collected from leaf litter. We also report new occurrences for the genus west of the Andes mountain range. Our work increases the number of known Neotropical Micranops species to seven and extends the known distribution range for the genus in South America. |
38095828 | Adaptive and Maladaptive Clonal Hematopoiesis in Telomere Biology Disorders. | Telomere biology disorders (TBDs) are germline-inherited conditions characterized by reduction in telomerase function, accelerated shortening of telomeres, predisposition to organ-failure syndromes, and increased risk of neoplasms, especially myeloid malignancies. In normal cells, critically short telomeres trigger apoptosis and/or cellular senescence. However, the evolutionary mechanism by which TBD-related telomerase-deficient cells can overcome this fitness constraint remains elusive. |
38095834 | "Soggy-Sand" Chemistry for High-Voltage Aqueous Zinc-Ion Batteries. | The narrow electrochemical stability window, deleterious side reactions, and zinc dendrite growth all act to prevent the practical use of aqueous zinc-ion batteries. Here, aqueous "soggy-sand" electrolytes (synergistic electrolyte-insulator dispersions) with multiple functions have been developed for achieving high-voltage Zn-ion batteries. We reveal how these electrolytes bring a unique combination of benefits, synergizing the advantages of solid and liquid electrolytes. The oxide additions adsorb water molecules and trap anions, causing a network of space charge layers with increased Zn<sup>2+</sup> transference number and reduced interfacial resistance. They beneficially modify the hydrogen bond network and the solvation of Zn<sup>2+</sup> , thereby influencing the mechanical and electrochemical properties, and causing the Mn<sup>2+</sup> in the solution to be oxidized and thus providing additional capacity. As a result, the best performing Al<sub>2</sub> O<sub>3</sub> -based "soggy-sand" electrolyte exhibits a long-life of 2500 h and dendrite-free deposition behavior in Zn||Zn cells. Furthermore, it increases the charging cut-off voltage for Zn/MnO<sub>2</sub> full cells to 2 V (versus Zn<sup>2+</sup> /Zn), allowing for an extremely high specific capacity of 344 mAh g<sup>-1</sup> at 1 A g<sup>-1</sup> to be attained. Even under practical conditions with a high mass loading of 10 mg<sub>MnO2</sub> cm<sup>-2</sup> , it yields a promising specific capacity of 189 mAh g<sup>-1</sup> at 1 A g<sup>-1</sup> after 500 cycles. The concept of "soggy-sand" chemistry thus provides a new approach for the design of powerful and universal electrolyte for aqueous batteries. This article is protected by copyright.

38095836 | Development of CAR-NK Cells Targeting cSCC-Specific Antigens for Precision Immunotherapy. | Cutaneous squamous cell carcinoma (cSCC), a non-melanoma skin cancer that is frequently diagnosed, is distinguished by its propensity for aggressive behavior, frequent poor response to standard therapy, and capacity to metastasize to distant areas. Utilizing the body's natural immune defense mechanisms, particularly through the use of chimeric antigen receptor (CAR) technology, is receiving increasing attention in the dynamic field of oncological therapies. Although T cells have received most of the attention, this strategy has proven to be highly effective in battling some blood-related malignancies. However, there are considerable challenges when using this method in the context of solid tumors. The innate immune system's natural killer (NK) cells are essential parts because they have the ability to detect and destroy cancer cells. CAR-NK cells are a very promising approach because they combine the natural cytotoxic properties of natural killer (NK) cells with the precise targeting skills of chimeric antigen receptor (CAR) technology. With the use of this integrated strategy, the intrinsic diversity of cutaneous squamous cell carcinoma (cSCC) tumors may be successfully targeted, increasing treatment effectiveness and lowering the risk of tumor recurrence. This tactic is improved by the development of dual-specificity chimeric antigen receptors (CARs), which fully resolve the antigen presentation heterogeneity among tumor cells. In conclusion, the use of CAR-NK cells that precisely target cSCC-specific antigens has the potential to drastically transform therapy approaches for cSCC as well as other difficult solid tumors as oncological research advances. In order to create chimeric antigen receptor (CAR)-natural killer (NK) cells that particularly target antigens linked to cutaneous squamous cell carcinoma (cSCC), the goal of this protocol is to present a detailed method. The ultimate objective is to lay the groundwork for the development of precision immunotherapy. |
38095835 | Autophagy Analysis: A Step-by-Step Simple Practical Guide for Immunofluorescence and Western Blotting. | Autophagy is a vital cellular process responsible for breaking down faulty cellular components and organelles, ultimately routed through lysosomes for degradation. This intricate mechanism involves the translocation of LC3, a cytoplasmic protein, onto the autophagosome membranes. As a result, it becomes feasible to discern cells engaged in autophagy by employing fluorescent markers designed for LC3 or other indicative autophagy markers. Although a variety of techniques such as immunofluorescence and western blotting serve as indispensable tools for assessing autophagy, the definitive confirmation comes from the visualization of autophagosomes using transmission electron microscopy. While numerous protocols for antibody staining can be found in scientific literature and on antibody suppliers' websites, these procedures often demand significant time and financial resources for setup. This chapter endeavors to provide a user-friendly and cost-effective guide for practitioners seeking proficiency in immunofluorescence staining and western blotting techniques. |
38095837 | Selection of Fusion Levels in Adolescent Idiopathic Scoliosis. | PURPOSE OF REVIEW: Posterior spinal fusion (PSF) is the preferred treatment for adolescent idiopathic scoliosis (AIS) patients with surgical range curves. Selection of the proper upper and lower instrumented vertebrae (UIV and LIV) is essential in curve correction and achieving a successful outcome, while preventing short and long-term complications. RECENT FINDINGS: The literature lacks high-level evidence, especially on outcomes of modern surgical techniques. However, evidence seems to show that a great majority of AIS patients have excellent clinical and functional long-term outcomes after PSF. We have reviewed the evidence and provided our level selection recommendations, which should be weighed against the body of evidence on the topic when selecting fusion levels in AIS. |
38095833 | Complication and conversion outcomes in transoral endoscopic thyroidectomy vestibular approach (TOETVA): a retrospective multicenter propensity score-matched cohort study. | Transoral endoscopic thyroidectomy with vestibular approach (TOETVA) is a scarless thyroid surgery used as an alternative to open conventional surgery. Our aim was to investigate possible risk factors for complications and conversion during TOETVA. The study was conducted internationally by centres from Turkiye, the Republic of Korea, Italy, and Peru. A total of 406 patients who underwent TOETVA and were ≥ 18 years of age were included in the study. Demographic, pre-, intra-, and postoperative data were collected and compared between the groups with/without complication/conversion to identify possible predictors of complication/conversion. Subsequently, patients with complication/conversion were matched by the hospital, age, sex, and American Society of Anesthesiologists classification score using a propensity score (PSM) of 1:3 to eliminate confounding differences. Results were reported for the un-matched and matched groups. Complications occurred in 11 (2.7%) patients. High body mass index (26.4 ± 3.4 vs. 23.3 ± 3.7, p = 0.007), larger tumor size (1.7 ± 1.3 cm. vs. 1.1 ± 1.0 cm, p = 0.012), larger thyroid volume (20.0 ± 9.2 vs. 12.8 ± 8.5, p = 0.007) and long operation time (127.8 ± 45.0 min. vs. 97.7 ± 38.5 min., p = 0.008) were significantly associated with complications in un-matched analyses. Older age (42.7 ± 8.0 vs. 34.9 ± 9.2, p = 0.023), high BMI (26.7 ± 3.2 vs. 23.3 ± 3.7, p = 0.012), and longer operation time (160.1 ± 54.1 min. vs. 97.4 ± 37.8, p = 0.001) were significantly related to conversion in un-matched analyses. However, significance was lost after PSM for both complication and conversion. The data from this study conducted on TOETVA cases do not suggest a risk factor for complications and conversion with PSM. |
38095832 | Translating mesenchymal stem cell and their exosome research into GMP compliant advanced therapy products: Promises, problems and prospects. | Mesenchymal stem cells (MSCs) are one of the few stem cell types used in clinical practice as therapeutic agents for immunomodulation and ischemic tissue repair, due to their unique paracrine capacity, multiple differentiation potential, active components in exosomes, and effective mitochondria donation. At present, MSCs derived from tissues such as bone marrow and umbilical cord are widely applied in preclinical and clinical studies. Nevertheless, there remain challenges to the maintenance of consistently good quality MSCs derived from different donors or tissues, directly impacting their application as advanced therapy products. In this review, we discuss the promises, problems, and prospects associated with translation of MSC research into a pharmaceutical product. We review the hurdles encountered in translation of MSCs and MSC-exosomes from the research bench to an advanced therapy product compliant with good manufacturing practice (GMP). These difficulties include how to set up GMP-compliant protocols, what factors affect raw material selection, cell expansion to product formulation, establishment of quality control (QC) parameters, and quality assurance to comply with GMP standards. To avoid human error and reduce the risk of contamination, an automatic, closed system that allows real-time monitoring of QC should be considered. We also highlight potential advantages of pluripotent stem cells as an alternative source for MSC and exosomes generation and manufacture. |

38095841 | Methylated MFGE8 Promotes Early Brain Injury After Subarachnoid Hemorrhage and Inhibiting Autophagy of Nerve Cell. | Spontaneous subarachnoid hemorrhage (SAH) is a relatively common clinical hemorrhagic stroke crisis. The important role of early brain injury (EBI) and autophagy in SAH has been increasingly recognized in recent years. This study aims to investigate the function and the undergoing mechanism of MFGE8 in EBI after SAH. |
38095839 | Clinical and Molecular Characteristics of Gonadotroph Pituitary Tumors According to the WHO Classification. | Since 2017, hormone-negative pituitary neuroendocrine tumors expressing the steroidogenic factor SF1 have been recognized as gonadotroph tumors (GnPT) but have been poorly studied. To further characterize their bio-clinical spectrum, 54 GnPT defined by immunostaining for FSH and/or LH (group 1, n = 41) or SF1 only (group 2, n = 13) were compared and studied for SF1, βFSH, βLH, CCNA2, CCNB1, CCND1, caspase 3, D2R, and AIP gene expression by qRT-PCR. Immunohistochemistry for AIP and/or D2R was performed in representative cases. Overall, patients were significantly younger in group 1 (P = 0.040 vs group 2), with a similar trend excluding recurrent cases (P = 0.078), and no significant difference in gender, tumor size, invasion or Ki67. SF1 expression was similar in both groups but negatively correlated with the patient's age (P = 0.013) and positively correlated with βLH (P < 0.001) expression. Beta-FSH and AIP were significantly higher in group 1 (P = 0.042 and P = 0.024, respectively). Ki67 was unrelated to gonadotroph markers but positively correlated with CCNB1 (P = 0.001) and negatively correlated with CCND1 (P = 0.008). D2R and AIP were strongly correlated with each other (P < 0.001), and both positively correlated with SF1, βFSH, βLH, and CCND1. AIP immunopositivity was frequently observed in both groups, with a similar median score, and unrelated to Ki67. D2R immunostaining was best detected with a polyclonal antibody and mostly cytoplasmic. This study indicates that hormone-negative GnPT tend to occur in older patients but do not significantly differ from other GnPT in terms of invasion or proliferation. It also points out the current limits of D2R immunostaining in such tumors. |

38095842 | O- and N-Methyltransferases in benzylisoquinoline alkaloid producing plants. | Secondary metabolites such as benzylisoquinoline alkaloids (BIA) have attracted considerable attention because of their pharmacological properties and potential therapeutic applications. Methyltransferases (MTs) can add methyl groups to alkaloid molecules, altering their physicochemical properties and bioactivity, stability, solubility, and recognition by other cellular components. Five types of O-methyltransferases and two types of N-methyltransferases are involved in BIA biosynthesis. |
38095840 | Prevalence and Predictors of Hemorrhagic Foci on Long-term Follow-up MRI of Recent Single Subcortical Infarcts. | Hemorrhagic foci surrounding the lacune in the long-term evolution of recent single subcortical infarcts (RSSIs) remains largely unexplored. We aimed to determine the prevalence, characteristics, and predictors of hemorrhagic foci in patients with RSSI. From a prospective, longitudinal study of RSSIs, we recruited patients who underwent multimodal MRI assessments both at baseline and approximately one year after the stroke onset. Hemorrhagic foci were identified using susceptibility-weighted imaging (SWI). Among 101 patients with RSSI, nearly half (n = 45, 44.6%) had hemorrhagic foci within the index RSSI lesions on follow-up SWI. RSSIs with hemorrhagic foci formation were associated with a longer time to follow-up imaging (median 449 versus 401 days, P = 0.005) and higher likelihood of being located in the anterior circulation compared to those without hemorrhagic foci (88.9% versus 64.3%, P = 0.003). Hemorrhagic foci were also associated with larger lesion size (P < 0.001), a higher proportion of cavitation formation (P = 0.003), higher baseline NIHSS scores (P = 0.004), and poorer functional outcomes (P = 0.001). In the subset of RSSIs in the lenticulostriate artery (LSA) territory, after adjustment for covariates, larger initial lesion volume (OR 1.80, 95% CI 1.13-2.87; P = 0.014) and greater decreases in LSA total length (OR 0.59, 95% CI 0.36-0.96; P = 0.035) were independently associated with hemorrhagic foci formation. The extent of ischemia in the initial infarct is predictive of the presence of hemorrhagic residues. Our findings contribute to the current understanding of the mechanisms underlying the evolution of RSSIs. |
38095838 | Non-operative Management of Acute Knee Injuries. | Acute knee injuries are commonly encountered in both the clinical and sideline setting and may be treated operatively or non-operatively. This article describes an evidence-based approach to non-operative acute knee injury. This includes history, physical exam, imaging, and initial management. In addition, the non-operative management of three such injuries-ligament injury, meniscus injury, and patellar dislocation injury-will be discussed via a case-based practical approach. |

38095846 | Cytokines Expression Compared to the Determinants of Cellular Apoptosis Prominently Attributes to the Deleterious Effects of 'A' Determinant Surface Gene Mutations in HBV Transfected Hepatoma Cell Line. | Previous studies have explored the role of AKT protein in anti-apoptotic/proliferative activities. However, there has been a lack of information regarding the role of Akt in association with cytokines expression in HBV-related (wild type HBV and HBV with mutations of 'a' determinant region) studies either in the case of HBV infection or in transfected hepatoma cells. The present study tries to determine the role of Akt and cytokines expression in the presence of small surface gene mutants in the hepatoma cell line. |
38095847 | Role of MicroRNAs in Inflammatory Joint Diseases: A Review. | Inflammatory arthritis commonly initiates in the soft tissues lining the joint. This lining swells, as do the cells in it and inside the joint fluid, producing chemicals that induce inflammation signs such as heat, redness, and swelling. MicroRNA (miRNA), a subset of non-coding small RNA molecules, post-transcriptionally controls gene expression by targeting their messenger RNA. MiRNAs modulate approximately 1/3 of the human genome with their multiple targets. Recently, they have been extensively studied as key modulators of the innate and adaptive immune systems in diseases such as allergic disorders, types of cancer, and cardiovascular diseases. However, research on the different inflammatory joint diseases, such as rheumatoid arthritis, gout, Lyme disease, ankylosing spondylitis, and psoriatic arthritis, remains in its infancy. This review presents a deeper understanding of miRNA biogenesis and the functions of miRNAs in modulating the immune and inflammatory responses in the above-mentioned inflammatory joint diseases. According to the literature, it has been demonstrated that the development of inflammatory joint disorders is closely related to different miRNAs and their specific regulatory mechanisms. Furthermore, they may present as possible prognostic and diagnostic biomarkers for all diseases and may help in developing a therapeutic response. However, further studies are needed to determine whether manipulating miRNAs can influence the development and progression of inflammatory joint disorders. |
38095848 | Diluting the resistance of built-in electric fields in oxygen vacancy-enriched Ru/NiMoO4-x for enhanced hydrogen spillover in alkaline seawater splitting. | Recently, hydrogen spillover based binary (HSBB) catalysts have received widespread attention due to the sufficiently utilized reaction sites. However, the specific regulation mechanism of spillover intensity is still unclear. Herein, we have fabricated oxygen vacancies enriched Ru/NiMoO4-x to investigate the internal relationship between electron supply and mechanism of hydrogen spillover enhancement. The DFT calculations cooperates with in-situ Raman spectrum to uncover that the H* spillover from NiMoO4-x to Ru. Meanwhile, oxygen vacancies weakened the electron supply from Ru to NiMoO4-x, which contributes to dilute the resistance of built-in electric field (BEF) for hydrogen spillover. In addition, the higher ion concentration in electrolyte will promote the H* adsorption step obviously, which is demonstrated by in-situ EIS test. As a result, the Ru/NiMoO4-x exhibits a low overpotential of 206 mV at 3.0 A cm-2, a small Tafel slope of 28.8 mV dec-1, and an excellent durability of 550 h at the current density of 0.5 A cm-2 for HER in 1.0 M KOH seawater. |
38095844 | Exploring the Potential of Nickel Oxide Nanoparticles Synthesized from Dictyota bartayresiana and its Biological Applications. | The present study validates the impact of nickel oxide nanoparticles (NiONPs) biosynthesized from the brown seaweed Dictyota bartayresiana (DB) and its biological applications. The phytochemicals analyzed in the seaweed extract served as a reducing, capping or stabilizing agent in the formation of nanoparticles. UV visible spectrum of nickel oxide nanoparticles synthesized from DB (DB-NiONPs) represented a prominent peak at 392 nm which validates its formation. Fourier Transmission Infrared Spectroscopy (FT-IR) showcased the presence of functional groups in the biomolecules which aids in the stabilization of DB-NiONPs. The X-ray diffractometry (XRD) revealed the crystalline nature of DB-NiONPs and the particle size was calculated as 18.26 nm. The Scanning electron microscope (SEM) illustrates the irregularly shaped DB-NiONPs and the desired elements were depicted in energy dispersive X-ray (EDX) spectrum which confirms the purity of DB-NiONPs. The DB-NiONPs efficiently decolorised the Black B133 (BB133) dye to 86% in 25 min. The data of adsorption studies well fitted into Langmuir isotherm and pseudo-second order kinetic model. The thermodynamic study substantiated the spontaneous, feasible and endothermic process of adsorption. DB-NiONPs revealed enhanced antimicrobial, larvicidal and nematicidal activities against the selected microbes, larva of Culex pipens and juveniles of Meloidogyne incognita respectively. The phytotoxicity studies revealed the DB-NiONPs had a positive impact on the germination and growth of green gram seedlings. |
38095850 | Buprenorphine and Opioid Use Disorder Training: Graduate Nursing Curricula Recommendations. | Opioid use disorder (OUD) is a public health emergency, with a shortage of providers trained to prescribe buprenorphine for OUD treatment. We conducted a systematic review to examine advanced practice RN (APRN) and medical school programs that included OUD content or Drug Addiction Treatment Act waiver training and evaluate the outcomes of those curricular modifications. APRN and medical school programs that provided OUD content or waiver training saw improvements in students' knowledge and self-efficacy for managing buprenorphine treatment and reduced stigma toward individuals with OUD. Students' perceptions of training were largely positive, and the programs' results indicated improved practice outcomes related to the use of buprenorphine. Further inclusion of OUD content and training in APRN curricula will increase the number of capable buprenorphine prescribers, which will increase access to buprenorphine for individuals with OUD.

38095851 | Healing Trauma While Staying at Home: Using Telehealth to Conduct a Brief Treatment Program for Posttraumatic Stress Disorder. | Studies suggest that a three-session brief treatment program (Brief Relaxation, Education, and Trauma Healing [BREATHE]) can help treat posttraumatic stress disorder (PTSD) and symptoms of trauma; however, the program has not been examined via telehealth. Thus, the current study evaluated the feasibility of BREATHE delivered via telehealth. The intervention included breathing retraining and psychoeducation about PTSD and trauma. Thirty participants from the community with confirmed PTSD diagnoses participated in this telehealth program. Treatment retention was high, and participants showed decreased PTSD symptoms, posttraumatic cognitions, depression, anxiety, overall psychiatric symptoms, and internalized stigma and increased resiliency at posttreatment and 3-month follow up. Results suggest that a telehealth brief treatment program for PTSD is feasible and effective for individuals with PTSD.

38095852 | Positive PTSD Screening and Its Health Correlates in Patients With HIV in Urban Primary Care Settings. | Posttraumatic stress disorder (PTSD) is underdiagnosed and undertreated in primary care, especially among African American individuals. The current study assessed documentation rates of PTSD and clinical health correlates among 135 predominantly African American patients with HIV and positive PTSD screens in a primary care unit. The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) and a retrospective chart review of 135 patients with HIV were conducted. On the PCPTSD-5 (cut point of 3), approximately one half of patients (49.6%; <i>n</i> = 67) had probable PTSD; however, only 11.9% of patients (<i>n</i> = 16) had a chart diagnosis of PTSD. A positive PTSD screen was associated with higher rates of depression and insomnia, but not anxiety, alcohol use, drug use, or pain in patients with HIV. Multi-morbidity of HIV, major depression, and positive PTSD screens was associated with increased risk for asthma, number of medical diagnoses, depression, insomnia, and anxiety. Findings highlight the need for trauma-informed care in primary care settings for people with PTSD and HIV. Larger samples are warranted to further explore health correlates of PTSD.

38095849 | Targeted genetic therapies for inherited disorders that affect both cardiac and skeletal muscle. | Skeletal myopathies and ataxias with secondary cardiac involvement are complex, progressive and debilitating conditions. As life expectancy increases across these conditions, cardiac involvement often becomes more prominent. This highlights the need for targeted therapies that address these evolving cardiac pathologies. Musculopathies by and large lack cures that directly target the genetic basis of the diseases; however, as our understanding of the genetic causes of these conditions has evolved, it has become tractable to develop targeted therapies using biologics, to design precision approaches to target the primary genetic causes of these varied diseases. Using the examples of Duchenne muscular dystrophy, Friedreich ataxia and Pompe disease, we discuss how the genetic causes of such diseases derail diverse homeostatic, energetic and signalling pathways, which span multiple cellular systems in varied tissues across the body. We outline existing therapeutics and treatments in the context of emerging novel genetic approaches. We discuss the hurdles that the field must overcome to deliver targeted therapies across the many tissue types affected in primary myopathies. NEW FINDINGS: What is the topic of this review? Overlapping disease pathomechanisms and therapeutic opportunities in neuromuscular, skeletal and cardiac muscle diseases in the context of novel genetic therapies. What advances does it highlight? This review outlines the diverse genetic changes that drive pathomechanism across a set of neuromuscular conditions and highlight the emerging targeted biological therapies that are being developed to treat these conditions, with additional discussion of the hurdles to actualising genetically targeted precision medicine. |
38095853 | Relationships Among Demographic Factors, Stigma, Social Support, and Self-Management in Individuals With Bipolar Disorder in Remission. | The current cross-sectional study aimed to investigate the extent to which demographic characteristics, stigma, and social support impact the self-management abilities of individuals with bipolar disorder in remission. Participants (<i>N</i> = 114) completed a demographic questionnaire, Self-Stigma Scale-Short Form, Social Support Rating Scale, and Self-Management Scale for Patients With Bipolar Disorder. Mean scores were 60.65 (<i>SD</i> = 10.42) for self-management, 35.76 (<i>SD</i> = 7.14) for social support, and 21.38 (<i>SD</i> = 5.06) for stigma. In the univariate analysis, age, educational level, method of payment for care, illness duration, and number of hospitalizations demonstrated significant associations with self-management (<i>p</i> < 0.05). Correlation analysis revealed a positive correlation between self-management and social support (<i>r</i> = 0.574, <i>p</i> < 0.01) and negative correlations between self-management and stigma (<i>r</i> = -0.489, <i>p</i> < 0.01) and stigma and social support (<i>r</i> = -0.476, <i>p</i> < 0.01). Multiple linear regression analysis included number of hospitalizations (β = -3.818), social support (β = 0.436), literacy (β = 2.132), and stigma (β = -0.397). Individuals in remission from bipolar disorder exhibit moderate levels of self-management. Follow-up interventions should prioritize enhancing social support and addressing stigma to promote improved self-management and overall well-being.

38095856 | ICBcomb: a comprehensive expression database for immune checkpoint blockade combination therapy. | The success of immune checkpoint blockade (ICB) promotes the immunotherapy to be a new pillar in cancer treatment. However, the low response rate of the ICB therapy limits its application. To increase the response rate and enhance efficacy, the ICB combination therapy has emerged and its clinical trials are increasing. Nevertheless, the gene expression profile and its pattern of ICB combination were not comprehensively studied, which limits the understanding of the ICB combination therapy and the identification of new drugs. Here, we constructed ICBcomb (http://bioinfo.life.hust.edu.cn/ICBcomb/), a comprehensive database, by analyzing the human and mouse expression data of the ICB combination therapy and comparing them between groups treated with ICB, other drugs or their combinations. ICBcomb contains 1399 samples across 29 cancer types involving 52 drugs. It provides a user-friendly web interface for demonstrating the results of the available comparisons in the ICB combination therapy datasets with five functional modules: [1, 2] the 'Dataset/Disease' modules for browsing the expression, enrichment and comparison results in each dataset or disease; [3] the 'Gene' module for inputting a gene symbol and displaying its expression and comparison results across datasets/diseases; [4] the 'Gene Set' module for GSVA/GSEA enrichment analysis on the built-in gene sets and the user-input gene sets in different comparisons; [5] the 'Immune Cell' module for immune cell infiltration comparison between different groups by immune cell abundance analysis. The ICBcomb database provides the first resource for gene expression profile and comparison in ICB combination therapy, which may provide clues for discovering the mechanism of effective combination strategies and new combinatory drugs. |
38095857 | Differentiable rotamer sampling with molecular force fields. | Molecular dynamics (MD) is the primary computational method by which modern structural biology explores macromolecule structure and function. Boltzmann generators have been proposed as an alternative to MD, by replacing the integration of molecular systems over time with the training of generative neural networks. This neural network approach to MD enables convergence to thermodynamic equilibrium faster than traditional MD; however, critical gaps in the theory and computational feasibility of Boltzmann generators significantly reduce their usability. Here, we develop a mathematical foundation to overcome these barriers; we demonstrate that the Boltzmann generator approach is sufficiently rapid to replace traditional MD for complex macromolecules, such as proteins in specific applications, and we provide a comprehensive toolkit for the exploration of molecular energy landscapes with neural networks. |
38095858 | Beyond Mentalizing: Epistemic Trust and the Transmission of Culture. | We explore the interpersonal origins of human culture, arguing that culture emerges as a necessary consequence of our helplessness in infancy, which in turn requires a greater degree of collaboration and social organization than is necessary for other mammals. We propose a model of cultural transmission that depends on a dyadic interpersonal process whose vicissitudes can have a lifelong impact. We explore the role played by imagining subjectively experienced psychological states and processes in others, which we have defined as <i>mentalizing</i>, in the process of cultural transmission, and propose that mentalizing is key to the establishment of epistemic trust-that is to say, an experience of trust that enables the individual to absorb and use the knowledge they are being offered. We suggest that psychoanalysis can be viewed as a paradigmatic example of a process of transferring knowledge from one human being (the teacher, the caregiver, the analyst) to another (the learner, the young person, the patient) and argue that the mechanisms of psychic change in analysis cannot be fully understood without appreciating this aspect of the biological/evolutionary origins of our essential humanity. Finally, we discuss the clinical implications of the model we are proposing for the psychoanalytic process. |
38095859 | Transference: The Matrix of the Frame. | I use the clinical example of a traumatized adolescent to talk about how a transference experience creates the frame where the analytic work occurs. Out of the external boundaries of the relationships with an object, the internal frame, the womb of transformation processes, is created. The analyst's capacity to wait is essential for the transformation that creates and shapes the transference experience, which, like playing, becomes the matrix of the frame where it happens as it happens. As the traumatic experiences find their place in the transference and begin to be integrated, the adolescent becomes more present and real in the session. |
38095860 | To Feel in My Flesh: Receptivity, Resonance, Representation, and The Beta Screen. | When we are confronted with the challenge of trying to fully convey or describe something about human life and emotional experience, we find ourselves up against the very limitations of language. This problem becomes especially relevant as we attempt to expand psychoanalytic theory so as to enable us to "approach a mental life unmapped by the theories elaborated for the understanding of neurosis" (Bion1962, p. 37). This paper seeks to aid in that expansion by revisiting Bion's early writings about the beta screen, extending his conclusions about communication from the psychotic part of the mind to the broad area of the unrepresented (the unstructured unconscious), suggesting that there is often a potentially communicative meaning, a mute plea for intersubjective regulatory assistance (alpha function), embedded in the unconscious evocation of emotions in the object and that this cry for help may be encrypted in even the most seemingly destructive, resistant and oppositional patients. |
38095861 | Meeting Patients Where They Are: Construction And Maintenance Of Analytic Intimacy. | This paper aims to describe the processes of construction and maintenance of analytic intimacy, understood as a shared state of relative internal freedom that is most permeable to preconscious and unconscious communications, which facilitate the processes of subjectivation, dreaming, and digestion of unprocessed trauma. The author illustrates the theoretical and technical features related to the concept of intimacy, highlighting the transformations of a clinical case followed in supervision. This article is presented in the form of a conversation with the supervisee, so as to evoke in the reader the dialogic and co-constructive experience of thought construction. |
38095863 | On Identity and the Political in Psychoanalysis. | Weaving subjective musings with theoretical speculation, this paper explores various themes on the question of identity. I consider identity as identification with a social location, where that social location is a function of groups. As such, identity is inherently contingent, a relational affair, a soft assembly. Though not a particularly psychoanalytic concept, identity is currently being tasked with considerable work in psychoanalysis: functioning as a hinge between the dual registers of the personal and social unconscious. Like any symptom, the term identity both obscures and indexes, signaling the urgent need for a radical revision of theory. The more we use the contingency of identity-how we find ourselves identified (by others as much as by ourselves) in this place and time, whatever this might be-rather than its fixity, thought to transcend place and time, the more that the concept of identity can be used in a specifically psychoanalytic way to help us explore the terrain of the political, which I distinguish from the terrain of politics proper. These ideas are employed to consider the current moment in psychoanalytic organizational life, which takes place under the sign of a fundamental paradigm shift (that is to say: catastrophic change). |

38095866 | The most exposed regions of SARS-CoV-2 structural proteins are subject to strong positive selection and gene overlap may locally modify this behavior. | We have analyzed the selection pressure of all severe acute respiratory syndrome coronavirus 2 genes by means of the nonsynonymous (Ka) to synonymous (Ks) substitution rate. We found that protein-coding genes are exposed to strong positive selection, especially in the regions of interaction with other molecules (host receptor and genome of the virus itself). However, overlapping coding regions are more protected and show negative selection. This suggests that this measure could be used to study viral gene function as well as overlapping genes. |
38095865 | New Awareness of the Interplay Between the Gut Microbiota and Circadian Rhythms. | Circadian rhythms influence various aspects of the biology and physiology of the host, such as food intake and sleep/wake cycles. In recent years, an increasing amount of genetic and epidemiological data has shown that the light/dark cycle is the main cue that regulates circadian rhythms. Other factors, including sleep/wake cycles and food intake, have necessary effects on the composition and rhythms of the gut microbiota. Interestingly, the gut microbiota can affect the circadian rhythm of hosts in turn through contact-dependent and contact-independent mechanisms. Furthermore, the gut microbiota has been shown to regulate the sleep/wake cycles through gut-brain-microbiota interaction. In addition to diabetes, the gut microbiota can also intervene in the progression of neuro- degenerative diseases through the gut-brain-microbiota interaction, and also in other diseases such as hypertension and rheumatoid arthritis, where it is thought to have a spare therapeutic potential. Even though fecal microbiota transplantation has good potential for treating many diseases, the risk of spreading intestinal pathogens should not be ignored. |

38095869 | Effects of riboflavin in the treatment of brain damage caused by oxygen deprivation: an integrative systematic review. | Brain oxygen deprivation causes morphological damage involved in the formation of serious pathological conditions such as stroke and cerebral palsy. Therapeutic methods for post-hypoxia/anoxia injuries are limited and still have deficiencies in terms of safety and efficacy. Recently, clinical studies of stroke have reported the use of drugs containing riboflavin for post-injury clinical rehabilitation, however, the effects of vitamin B2 on exposure to cerebral oxygen deprivation are not completely elucidated. This review aimed to investigate the potential antioxidant, anti-inflammatory and neuroprotective effects of riboflavin in cerebral hypoxia/anoxia. After a systematic search, 21 articles were selected, 8 preclinical and 12 clinical studies, and 1 translational study. Most preclinical studies used B2 alone in models of hypoxia in rodents, with doses of 1-20 mg/kg (in vivo) and 0.5-5 µM (in vitro). Together, these works suggested greater regulation of lipid peroxidation and apoptosis and an increase in neurotrophins, locomotion, and cognition after treatment. In contrast, several human studies have administered riboflavin (5 mg) in combination with other Krebs cycle metabolites, except one study, which used only B2 (20 mg). A reduction in lactic acidosis and recovery of sensorimotor functions was observed in children after treatment with B2, while adults and the elderly showed a reduction in infarct volume and cognitive rehabilitation. Based on findings from preclinical and clinical studies, we conclude that the use of riboflavin alone or in combination acts beneficially in correcting the underlying brain damage caused by hypoxia/anoxia and its inflammatory, oxidative, and behavioral impairments. |
