This study aimed to investigate the structural and metabolic changes in cumulus cells of underweight women and their effects on oocyte maturation and fertilization. The cytoplasmic ultrastructure was analyzed by electron microscopy, mitochondrial membrane potential by immunofluorescence, and mitochondrial DNA copy number by relative quantitative polymerase chain reaction. The expression of various proteins including the oxidative stress-derived product 4-hydroxynonenal (4-HNE) and autophagy and apoptosis markers such as Vps34, Atg-5, Beclin 1, Lc3-I, II, Bax, and Bcl-2 was assessed and compared between groups. Oocyte maturation and fertilization rates were lower in underweight women (P < 0.05), who presented with cumulus cells showing abnormal mitochondrial morphology and increased cell autophagy. Compared with the mitochondrial DNA copies of the control group, those of the underweight group increased but not significantly. The mitochondrial membrane potential was similar between the groups (P = 0.8). Vps34, Atg-5, Lc3-II, Bax, and Bcl-2 expression and 4-HNE levels were higher in the underweight group compared with the control group (P < 0.01); however, the Bax/Bcl-2 ratio was lower in the underweight group compared with the control group (P = 0.031). Additionally, Beclin 1 protein levels were higher in the underweight group compared with the control group but without statistical significance. In conclusion, malnutrition and other conditions in underweight women may adversely affect ovulation, and the development, and fertilization of oocytes resulting from changes to the intracellular structure of cumulus cells and metabolic processes. These changes may lead to reduced fertility or unsatisfactory reproduction outcomes in women.

AIMS: Following myocardial infarction (MI), the heart repairs itself via a fibrotic repair response. The degree of fibrosis is determined by the balance between deposition of extracellular matrix (ECM) by activated fibroblasts and breakdown of nascent scar tissue by proteases that are secreted predominantly by inflammatory cells. Excessive proteolytic activity and matrix turnover has been observed in human heart failure, and protease inhibitors in the injured heart regulate matrix breakdown. Serine protease inhibitors (Serpins) represent the largest and the most functionally diverse family of evolutionary conserved protease inhibitors, and levels of the specific Serpin, SerpinA3, have been strongly associated with clinical outcomes in human MI as well as non-ischaemic cardiomyopathies. Yet, the role of Serpins in regulating cardiac remodelling is poorly understood. The aim of this study was to understand the role of Serpins in regulating scar formation after MI.
METHODS AND RESULTS: Using a SerpinA3n conditional knockout mice model, we observed the robust expression of Serpins in the infarcted murine heart and demonstrate that genetic deletion of SerpinA3n (mouse homologue of SerpinA3) leads to increased activity of substrate proteases, poorly compacted matrix, and significantly worse post-infarct cardiac function. Single-cell transcriptomics complemented with histology in SerpinA3n-deficient animals demonstrated increased inflammation, adverse myocyte hypertrophy, and expression of pro-hypertrophic genes. Proteomic analysis of scar tissue demonstrated decreased cross-linking of ECM peptides consistent with increased proteolysis in SerpinA3n-deficient animals.
CONCLUSION: Our study demonstrates a hitherto unappreciated causal role of Serpins in regulating matrix function and post-infarct cardiac remodelling.
OBJECTIVE: Tai Chi is a common, reliable, and non-pharmacological treatment method used in COPD disease management. This review investigated the effect of Tai Chi on disease and symptom management in COPD patients.
METHODOLOGY: This study was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P).
RESULTS: The results showed that the Qigong, Sun, and Yang styles of Tai Chi are used for COPD patients. Trials compared Tai Chi with routine care, pulmonary rehabilitation added to routine care, and mind-body breathing. Tai Chi interventions were usually administered for a duration of 12 to 24 weeks. The results indicate that Tai Chi positively affects lung functions, exercise capacity, multidimensional perceived social support, diaphragm strength, quadriceps strength in the legs, self-care, self-efficacy, dyspnea, fatigue, anxiety, and depression.
CONCLUSION: Tai Chi is a safe and effective exercise for COPD patients with comorbidities. It is superior to mind-body breathing and routine care and as good as pulmonary rehabilitation but is easier to practice. However, longer-term studies with larger samples are needed to validate the findings of the study.
INTRODUCTION: This review aims to evaluate current practices regarding spine immobilization in pediatric trauma patients to evaluate their efficacy, reliability, and impact on clinical outcomes to guide future research and improved evidence-based practice guidelines.
METHODS: PubMed, ProQuest, Embase, Google Scholar, and Cochrane were queried for studies pertaining to spinal immobilization practices in pediatric trauma patients. Articles were separated into studies that explored both the efficacy and clinical outcomes of spine immobilization. Outcomes evaluated included frequency of spinal imaging, self-reported pain level, emergency department length of stay (ED-LOS), and ED disposition.
RESULTS: Six articles were included, with two studies examining clinical outcomes and 4 studies evaluating the efficacy and reliability of immobilization techniques. Immobilized children were significantly more likely to undergo cervical spine imaging (OR 8.2, p < 0.001), be admitted to the floor (OR 4.0, p < 0.001), be taken to the ICU or OR (OR 5.3, p < 0.05) and reported a higher median pain score. Older children were significantly more likely to be immobilized. No immobilization techniques consistently achieved neutral positioning, and patients most often presented in a flexed position. Lapses in immobilization occurred in 71.4% of patients.
CONCLUSION: Immobilized pediatric patients underwent more cervical radiographs, and had higher hospital and ICU admission rates, and higher mean pain scores than those without immobilization. Immobilization was inconsistent across age groups and often resulted in lapses and improper alignment. Further research is needed to identify the most appropriate immobilization techniques for pediatric patients and when to use them.

Liquid-liquid phase separation (LLPS) describes many biochemical processes, including hydrogel formation, in the integrity of macromolecular assemblages and existence of membraneless organelles, including ribosome, nucleolus, nuclear speckles, paraspeckles, promyelocytic leukemia (PML) bodies, Cajal bodies (all exert crucial roles in cellular physiology), and evidence are emerging day by day. Also, phase separation is well documented in generation of plasma membrane subdomains and interplay between membranous and membraneless organelles. Intrinsically disordered regions (IDRs) of biopolymers/proteins are the most critical sticking regions that aggravate the formation of such condensates. Remarkably, phase separated condensates are also involved in epigenetic regulation of gene expression, chromatin remodeling, and heterochromatinization. Epigenetic marks on DNA and histones cooperate with RNA-binding proteins through their IDRs to trigger LLPS for facilitating transcription. How phase separation coalesces mutant oncoproteins, orchestrate tumor suppressor genes expression, and facilitated cancer-associated signaling pathways are unravelling. That autophagosome formation and DYRK3-mediated cancer stem cell modification also depend on phase separation is deciphered in part. In view of this, and to linchpin insight into the subcellular membraneless organelle assembly, gene activation and biological reactions catalyzed by enzymes, and the downstream physiological functions, and how all these events are precisely facilitated by LLPS inducing organelle function, epigenetic modulation of gene expression in this scenario, and how it goes awry in cancer progression are summarized and presented in this article.
The prevalence of fibromyalgia is approximately 2.7%, with a female-to-male ratio of 3:1. Although it is a relatively common syndrome, there are many doubts regarding its diagnosis and pathophysiology. In addition to the previously mentioned questions, this pathology has high social costs due to its association with the loss of labor productivity and it is characterized by being unresponsive to pharmacological treatment. Given the limited effectiveness of available therapeutic options, new therapeutic and diagnostic options have been sought. This scenario includes the use of different techniques of non-invasive brain stimulation, such as transcranial direct current magnetic stimulation (tDCS) and transcranial magnetic stimulation (TMS), which have already had promising results in reducing pain. In addition, TMS also allows measuring parameters that help to understand the reorganization of physiological processes. In this study, TMS is used to understand the pathophysiology of fibromyalgia, while tDCS allows modulating the excitability of the neuronal membrane potential of cortical and subcortical neural networks, producing a neuromodulatory effect of the top-down type. According to the evidence, the greatest impact on pain is associated with stimulation of the primary motor cortex (M1), but recent studies have shown the possible relationship between stimulation of extracerebral regions such as the cerebellum, with an analgesic effect present in healthy individuals and patients with different pathologies. In the same way, the cortical excitability measures obtained through TMS allow us to identify the imbalance between inhibitory and excitatory systems, related to pain perception and the analgesic response of endogenous mechanisms. In this research, our objective is to evaluate the effect of cerebellar tDCS on clinical measures of pain and cortical excitability in patients with fibromyalgia. This is a randomized, double-blind, controlled clinical trial, parallel, which has as its primary outcome, the evaluation of the variations in motor evoked potential (MEP) (neurophysiological outcome) and the numerical pain scale (NPS) as a clinical outcome. Secondary outcomes include the silent period (CSP), intra-cortical facilitation (ICF) and intra-cortical inhibition (ICI) obtained through TMS, the function of the descending modulatory path of pain by the conditioned modulation test (CPM test), the Brief Pain Inventory (BPI) and the pain thresholds by heat, pressure and cold. The intervention consists of a single tDCS session in which two devices will be used simultaneously. The active electrode will be placed in the cerebellum and/or in the primary motor cortex (4 stimulation protocols that will be implemented; active cerebellum electrode - active M1 electrode, sham cerebellum electrode - active M1 electrode, active cerebellum-M1 sham electrode, sham cerebellum electrode-M1 sham electrode) and the cathode in the contralateral supraorbital region. The equipment will apply a current of 2 mA for 20 minutes. In total, there will be 92 patients, divided into 4 intervention blocks and composed of 23 individuals each.
The antigen is prepared in primary or secondary cell cultures from chicken or duck embryos. The cultures are infected by apathogenic virus of Mark's disease, strain MDV-KOL-A BN-MDV-06-1985 adapted on cell cultures. The virus was isolated from poultry rearing without any visible clinical symptoms of the disease. It proliferates in cell cultures grown on glass, plastic, cultivated by stationary method or in rotating tanks or in suspension on microcarriers. After proliferation of the virus the cultivation medium is strained, cleared and the antigen is separated from the medium by ammonium sulphate precipitation. The precipitated antigen is thickened by centrifugation. The sulphates are removed by dialysis and the antigen concentration is adjusted to reach 25 to centuple of the original volume. It is stored in frozen or lyophilized state.
BACKGROUND: Massive modular endoprostheses have become a primary means of reconstruction after oncologic resection of a lower extremity tumor. These implants are commonly made with cobalt-chromium alloys that can undergo wear and corrosion, releasing cobalt and chromium ions into the surrounding tissue and blood. However, there are few studies about the blood metal levels in these patients.
QUESTION/PURPOSE: What is the whole blood cobalt and chromium ion level in patients with massive modular endoprostheses?
METHODS: We performed a cross-sectional study of our total joints registry to identify patients with a history of an endoprosthetic reconstruction performed at our institution. Patients who were alive at the time of our review in addition to those undergoing an endoprosthetic reconstruction after an oncologic resection were included. Whole blood samples were obtained from 27 (14 male and 13 female) patients with a history of a lower extremity oncologic endoprosthesis. The median time from surgery to blood collection was 8 years (range 6 months to 32 years). Blood samples were collected and stored in metal-free ethylenediaminetetraacetic acid tubes. Samples were analyzed on an inductively coupled plasma mass spectrometer in an International Organization for Standardization seven-class clean room using polytetrafluoroethylene-coated instruments to reduce the risk of metal contamination. The analytical measuring range was 1 to 200 ng/mL for chromium and cobalt. Cobalt and chromium levels were considered elevated when the blood level was ≥ 1 ppb.
RESULTS: Cobalt levels were elevated in 59% (16 of 27) of patients, and chromium levels were elevated in 26% (seven of 27). In patients with elevated metal ion values, 15 of 17 patients had a reconstruction using a Stryker/Howmedica Global Modular Replacement System implant.
CONCLUSION: Blood metal levels were elevated in patients who received reconstructions using modular oncology endoprostheses Future work is needed to establish appropriate follow-up routines and determine whether and when systemic complications occur because of elevated metal levels and how to potentially address these elevated levels when complications occur. Prospective and retrospective collaboration between multiple centers and specialty societies will be necessary to address these unknown questions in this potentially vulnerable patient group.
LEVEL OF EVIDENCE: Level IV, therapeutic study.
Participants will be provided with a nutritional strategy based on functional foods to use over the 2 week trial. These will be nopal, chía seeds, inulin, soy protein and genistein.
Understanding the dynamics of acute HIV infection can offer valuable insights into the early stages of viral behavior, potentially helping uncover various aspects of HIV pathogenesis. The standard viral dynamics model explains HIV viral dynamics during acute infection reasonably well. However, the model makes simplifying assumptions, neglecting some aspects of HIV infection. For instance, in the standard model, target cells are infected by a single HIV virion. Yet, cellular multiplicity of infection (MOI) may have considerable effects in pathogenesis and viral evolution. Further, when using the standard model, we take constant infected cell death rates, simplifying the dynamic immune responses. Here, we use four models-1) the standard viral dynamics model, 2) an alternate model incorporating cellular MOI, 3) a model assuming density-dependent death rate of infected cells and 4) a model combining (2) and (3)-to investigate acute infection dynamics in 43 people living with HIV very early after HIV exposure. We find that all models qualitatively describe the data, but none of the tested models is by itself the best to capture different kinds of heterogeneity. Instead, different models describe differing features of the dynamics more accurately. For example, while the standard viral dynamics model may be the most parsimonious across study participants by the corrected Akaike Information Criterion (AICc), we find that viral peaks are better explained by a model allowing for cellular MOI, using a linear regression analysis as analyzed by R2. These results suggest that heterogeneity in within-host viral dynamics cannot be captured by a single model. Depending on the specific aspect of interest, a corresponding model should be employed.
Gut microbiota symbiosis faces enormous challenge with increasing exposure to drugs such as environmental poisons and antibiotics. The gut microbiota is an important component of the host microbiota and has been proven to be involved in regulating spermatogenesis, but the molecular mechanism is still unclear. A male mouse model with gut microbiota depletion/dysbiosis was constructed by adding combined antibiotics to free drinking water, and reproductive parameters such as epididymal sperm count, testicular weight and paraffin sections were measured. Testicular transcriptomic and serum metabolomic analyses were performed to reveal the molecular mechanism of reproductive dysfunction induced by gut microbiota dysbiosis in male mice.This study confirms that antibiotic induced depletion of gut microbiota reduces sperm count in the epididymis and reduces germ cells in the seminiferous tubules in male mice. Further study showed that exosomes isolated from microbiota-depleted mice led to abnormally high levels of retinoic acid and decrease in the number of germ cells in the seminiferous tubules and sperm in the epididymis. Finally, abnormally high levels of retinoic acid was confirmed to disrupted meiotic processes, resulting in spermatogenesis disorders. This study proposed the concept of the gut microbiota-exosome-retinoic acid-testicular axis and demonstrated that depletion of the gut microbiota caused changes in the function of exosomes, which led to abnormal retinoic acid metabolism in the testis, thereby impairing meiosis and spermatogenesis processes.
This is a phase II, non-blinded, adaptively randomized trial. Patients with PDA are evaluated prior to protocol entry by standard of care testing, including EUS, contrast-enhanced helical abdominal CT scan, or MRI. Patients meeting NCCN criteria for potentially resectable (borderline or resectable) tumors will be eligible. Subjects are randomized to receive either 2 cycles of PGH - gemcitabine and nab-paclitaxel (1000 mg/m2 \& 125 mg/m2, respectively: days 1, 8, and 15) plus oral HCQ (1200 mg PO daily) - or PGH plus Avelumab (PGHA; days 1 and 15 of each 28-day cycle), by means of response-adaptive randomization based on Grade IIB or greater histologic response.

Surgical exploration and pancreatectomy is performed if technically feasible and all toxicities have resolved. HCQ is taken until the evening before surgery. Avelumab is administered every two weeks until up to one week prior to the date of surgery. The Study Coordinator informs subjects of the date of operation. Following successful surgical removal of tumors, patients are then be free to pursue standard of care adjuvant therapy options, at the discretion of their treating physician.
Glioblastoma (GBM) is a type of brain cancer categorized as a high-grade glioma. GBM is characterized by limited treatment options, low patient survival rates, and abnormal serotonin metabolism. Previous studies have investigated the tumor suppressor function of aldolase C (ALDOC), a glycolytic enzyme in GBM. However, it is unclear how ALDOC regulates production of serotonin and its associated receptors, HTRs. In this study, we analyzed ALDOC mRNA levels and methylation status using sequencing data and in silico datasets. Furthermore, we investigated pathways, phenotypes, and drug effects using cell and mouse models. Our results suggest that loss of ALDOC function in GBM promotes tumor cell invasion and migration. We observed that hypermethylation, which results in loss of ALDOC expression, is associated with serotonin hypersecretion and the inhibition of PPAR-γ signaling. Using several omics datasets, we present evidence that ALDOC regulates serotonin levels and safeguards PPAR-γ against serotonin metabolism mediated by 5-HT, which leads to a reduction in PPAR-γ expression. PPAR-γ activation inhibits serotonin release by HTR and diminishes GBM tumor growth in our cellular and animal models. Importantly, research has demonstrated that PPAR-γ agonists prolong animal survival rates and increase the efficacy of temozolomide in an orthotopic brain model of GBM. The relationship and function of the ALDOC-PPAR-γ axis could serve as a potential prognostic indicator. Furthermore, PPAR-γ agonists offer a new treatment alternative for glioblastoma multiforme (GBM).
