Introduction

Reliable and valid instruments are needed to measure the impact of mental health services and programs on the journeys of recovery of service users. The aim of this study was to explore the psychometric properties of the cross-culturally adapted 15-item Questionnaire about the Process of Recovery in Spain (QPR-15-SP).

Methods

One hundred and ten participants from three locations in Spain (Málaga, Barcelona and Madrid), who were users of primary and specialized mental health services, were interviewed from October 2021 to June 2022.

Results

The internal consistency obtained was excellent: ω  =.93 and α =.92. Temporal reliability using intraclass correlation coefficients was moderate (ICC=.684, p <.000). Regarding convergent validity, the QPR-15-SP had a moderate correlation with the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) (ρ =-.500, p <.000), a Visual Numeric Recovery Scale (VNRS) (ρ =.591, p <.000), and the Stages of Recovery Instrument (STORI) (r =.566, p <.000). Correlations between advanced stages of recovery and higher QPR-15-SP scores were found (Moratorium: ρ  =-.579, p <.000; Awareness: ρ =-.130, p =.189; Preparation: r =-.043, P=.665; Rebuilding: r =.460, p <.000; Growth: ρ  =.697, p <.000). In terms of divergent validity, the QPR-15-SP had low correlation with the DUKE-UNC Functional Social Support Scale (ρ =.273, p <.005). The confirmatory factor analysis of the 1-factor structure obtained reasonable goodness of fit indexes.

Discussion

The QPR-15-SP has acceptable psychometric properties, providing support for measuring recovery in Spain and allowing international comparison research.
Social connections and participation among people with mild cognitive impairment: barriers and recommendations
Authors: Zhu Di , Al Mahmud Abdullah , Liu Wei
Published: July 2023

Objective

Social connections and participation are essential for individuals with mild cognitive impairment (MCI) to prevent the progression of cognitive decline and enhance their overall well-being. However, existing research has primarily focused on environmental barriers, overlooking personal factors and the interconnected nature of these barriers. Moreover, there is a lack of understanding regarding social connections and participation challenges specific to people with MCI in low- and middle-income countries. Therefore, this study aimed to explore the barriers that hinder social connections and participation among people with MCI in China and investigate opportunities to design appropriate supportive interventions.

Methods

Thirty-one people with MCI (13 males and 18 females; mean age = 82.74 years, SD = 7.69; mean MoCA score = 21.26, SD = 2.44) and 13 caregivers were recruited to attend focus groups. In addition, 10 therapists were interviewed using a semi-structured interview guide. Focus groups and interviews were audio-recorded, transcribed, and analyzed using a framework analysis approach.

Results

We found that the ability to build social connections among people with MCI is affected by mobility challenges, intensive grandparenting responsibilities, availability of suitable activities, and feelings of exclusion in a closed-minded community environment. Personal reasons, such as lower social efficacy, inability to find suitable social activities, and intensive family responsibilities, discourage people with MCI from social participation. The digital literacy of people with MCI depends on their motivation to learn and use digital tools; people with MCI who live in a community have a higher digital literacy than those living in care centers. The motivation to achieve digital literacy is affected by perceived benefits, costs of technology use, and social influence.

Conclusion

Multidimensional initiatives are needed to address barriers to social connections, participation, and technology adoption among individuals with MCI. This includes organizing and engaging in social activities, promoting awareness and education on the importance of social participation, and exploring technology-based interventions to improve memory and storytelling abilities. These efforts can create a supportive environment and empower individuals with MCI to participate actively in social interactions, enhancing their overall well-being.

Published: July 2023

Chronic stress has become an epidemic with negative health risks including cardiovascular disease, hypertension, and diabetes. Traditional methods of stress measurement and monitoring typically relies on self-reporting. However, wearable smart technologies offer a novel strategy to continuously and non-invasively collect objective health data in the real-world. A novel electrocardiogram (ECG) feature has recently been introduced to the Apple Watch device. Interestingly, ECG data can be used to derive Heart Rate Variability (HRV) features commonly used in the identification of stress, suggesting that the Apple Watch ECG app could potentially be utilized as a simple, cost-effective, and minimally invasive tool to monitor individual stress levels. Here we collected ECG data using the Apple Watch from 36 health participants during their daily routines. Heart rate variability (HRV) features from the ECG were extracted and analyzed against self-reported stress questionnaires based on the DASS-21 questionnaire and a single-item LIKERT-type scale. Repeated measures ANOVA tests did not find any statistical significance. Spearman correlation found very weak correlations (p < 0.05) between several HRV features and each questionnaire. The results indicate that the Apple Watch ECG cannot be used for quantifying stress with traditional statistical methods, although future directions of research (e.g., use of additional parameters and Machine Learning) could potentially improve stress quantification with the device.

Published: July 2023

Background

Volatile organic compounds (VOCs) are a large group of chemicals widely used in People’s Daily life. There is increasing evidence of the cumulative toxicity of VOCs. However, the association between VOCs and the risk of COPD has not been reported.

Objective

We comprehensively evaluated the association between VOCs and COPD.

Methods

Our study included a total of 1,477 subjects from the National Health and Nutrition Examination Survey, including VOCs, COPD, and other variables in the average US population. Multiple regression models and smooth-curve fitting (penalty splines) were constructed to examine potential associations, and stratified analyses were used to identify high-risk groups.

Results

We found a positive association between blood benzene and blood o-xylene concentrations and COPD risk and identified a concentration relationship between the two. That is, when the blood benzene and O-xylene concentrations reached 0.28 ng/mL and 0.08 ng/mL, respectively, the risk of COPD was the highest. In addition, we found that gender, age, and MET influence the relationship, especially in women, young people, and people with low MET.

Significance

This study revealed that blood benzene and blood o-xylene were independently and positively correlated with COPD risk, suggesting that long-term exposure to benzene and O-xylene may cause pulmonary diseases, and providing a new standard of related blood VOCs concentration for the prevention of COPD.
Reconciling critical zone science with ecosystem and soil science—a personal-scientist perspective
Authors: Lohse Kathleen A.
Published: July 2023

The critical zone has been the subject of much discussion and debate as a term in the ecosystem, soil and earth system science communities, and there is a need to reconcile how this term is used within these disciplines. I suggest that much like watershed and soil ecosystems, the critical zone is an ecosystem and is defined by deeper spatial and temporal boundaries to study its structure and function. Critical zone science, however, expands the scope of ecosystem and soil science and more fully embraces the integration of earth sciences, ecology, and hydrology to understand key mechanisms driving critical zone functions in a place-based setting. This integration of multiple perspectives and expertise is imperative to make new discoveries at the interface of these disciplines. I offer solid examples highlighting how critical zone science as an integrative science contributes to ecosystem and soil sciences and exemplify this emerging field.

Authors: Karim Nurose , Stone Suzanne , Salter Amber , Gebreyohanns Mehari , Johnson Mark , Jones Erica
Published: July 2023

Background

Delays in acute treatment of ischemic stroke have been associated with worse outcomes. While having a non-English primary language has not been shown to delay receiving thrombolytic therapy, we assessed whether non-English primary language was associated with worse functional outcomes in patients receiving mechanical thrombectomy (MT).

Method

This is a retrospective study of our MT database from two comprehensive stroke centers from January 2016 to May 2021. Primary endpoint was discharge modified Rankin Scale (mRS) 0-2. Differences between English primary language (EPL) and non-English primary language (nEPL) groups were evaluated using an analysis of variance (ANOVA), Kruskal-Wallis and chi square test. Multivariable logistic regression was used to evaluate EPL vs. nEPL patients using data driven models determined by stepwise selection approach.

Result

We identified 276 patients receiving MT with 83% EPL and 17% nEPL patients. nEPL patients had higher mean hemoglobin A1c, were less likely to have insurance, and more likely to have symptomatic intracranial hemorrhage compared to EPL patients (Table). We observed a longer median ED arrival to groin puncture time in the nEPL group. No differences were observed in discharge or mRS 0-2 in the univariate or multivariable logistic regression.

Discussion

Despite finding longer ED length of stay among nEPL patients, there was no difference between nEPL and EPL in good functional outcome rates in patients treated with MT.

Edwardsiellosis caused by Edwardsiella tarda resulted in significant economic losses in aquaculture operations worldwide. This disease could infect a wide range of hosts, including freshwater, brackish water, and marine aquatic animals. Currently, antibiotics and vaccines are being used as prophylactic agents to overcome Edwardsiellosis in aquaculture. However, application of antibiotics has led to antibiotic resistance among pathogenic bacteria, and the antibiotic residues pose a threat to public health. Meanwhile, the use of vaccines to combat Edwardsiellosis requires intensive labor work and high costs. Thus, phytobiotics were attempted to be used as antimicrobial agents to minimize the impact of Edwardsiellosis in aquaculture. These phytobiotics may also provide farmers with new options to manage aquaculture species' health. The impact of Edwardsiellosis in aquaculture worldwide was elaborated on and highlighted in this review study, as well as the recent application of phytobiotics in aquaculture and the status of vaccines to combat Edwardsiellosis. This review also focuses on the potential of phytobiotics in improving aquatic animal growth performance, enhancing immune system function, and stimulating disease resistance.

Published: July 2023

Introduction

Smallholder pig farming is an important economic activity for many poor, rural communities in developing countries. Porcine cysticercosis is a growing public health risk in countries where pig rearing is popular. A sanitation-based intervention to reduce the prevalence of open defecation was completed in Busia County, Kenya in 2016. We capitalized on this third party intervention to evaluate its impact on porcine cysticercosis prevalence.

Methods

We conducted a comparative cross-sectional survey from August through to September 2021. Household selection was done using multistage sampling. Household questionnaire data on pig production, transmission, risk factors and awareness of porcine cysticercosis were collected from 251 households. Lingual palpation was used to test for cysticerci in 370 pigs while serum was tested for circulating antigen using Ag-ELISA. We compared results of our survey to an effective baseline, which was a near equivalent cross sectional survey conducted in 2012 before the third party sanitary intervention was established. The difference in prevalence was measured using Chi-square tests. Multivariable logistic regression analysis was used to identify risk factors for lingual cysts in pigs.

Results

The prevalence of palpable lingual cysts was estimated to be 3.8% (95% CI 2.3–6.3%) (14/370). This was 6% (95% CI 0.8–13.9%;p-value 0.0178) lower than the prevalence reported in the pre-implementation period of 9.7% (95% CI: 4.5–17.6%). Circulating antigen was detected in 2 samples (0.54%, 95% CI: 0.2–1.9). Latrine coverage was 86% (95% CI: 81–90%), which was 11% (95% CI: 4.8–16.8%;p < 0.001) higher than the pre-implementation period coverage of 75% (95% CI: 71–79%). There was reduced prevalence of lingual cysts in pigs from households that had a latrine (OR = 0.14; 95% CI: 0.05–0.43;p < 0.001) and where pigs were confined or tethered (OR = 0.27; 95% CI: 0.07–1.02;p = 0.053).

Conclusion

There was a reduction in the prevalence of porcine cysticercosis in Busia County over the study period from 2012 to 2021. This was not a trial design so we are unable to directly link the decline to a specific cause, but the data are consistent with previous research indicating that improved sanitation reduces porcine cysticercosis. Programs for controlling porcine cysticercosis should include a focus on sanitation in addition to other integrated One Health approaches.
Accurate identification and discrimination of Salmonella enterica serovar Gallinarum biovars Gallinarum and Pullorum by a multiplex PCR based on the new genes of torT and I137_14430
Authors: Song Li , Tan Ruimeng , Xiong Dan , Jiao Xinan , Pan Zhiming
Published: July 2023

Most cases of chicken salmonellosis are caused by Salmonella enterica serovar Gallinarum biovars Gallinarum and Pullorum, which lead to a significant morbidity and fatality rate. Although the conventional Kaufmann-White scheme is the reliable method for the serotyping of Salmonella, it does not distinguish between closely related biotypes like S. Pullorum and S. Gallinarum. Herein, we conducted a single one-step multiplex PCR assay that can identify and distinguish between S. Pullorum and S. Gallinarum in an accurate manner. This PCR method was based on three genes, including torT for S. Pullorum identification, I137_14430 for S. Gallinarum identification, and stn as the genus-level reference gene for Salmonella. By comparing S. Pullorum to S. Gallinarum and other serovars of Salmonella, in silico study revealed that only the former has a deletion of 126 bp-region in the carboxyl terminus of torT. The I137_14430 gene does not exist in S. Gallinarum. However, it is present in all other Salmonella serotypes. The multiplex PCR approach utilizes unique sets of primers that are intended to specifically target these three different genes. The established PCR method was capable of distinguishing between the biovars Pullorum and Gallinarum from the 29 distinct Salmonella serotypes as well as the 50 distinct pathogens that are not Salmonella, showing excellent specificity and exclusivity. The minimal amount of bacterial cells required for PCR detection was 100 CFU, while the lowest level of genomic DNA required was 27.5 pg/μL for both S. Pullorum and S. Gallinarum. After being implemented on the clinical Salmonella isolates collected from a poultry farm, the PCR test was capable of distinguishing the two biovars Pullorum and Gallinarum from the other Salmonella strains. The findings of the PCR assay were in line with those of the traditional serotyping and biochemical identification methods. This new multiplex PCR could be used as a novel tool to reinforce the clinical diagnosis and differentiation of S. Pullorum and S. Gallinarum, particularly in high-throughput screening situations, providing the opportunity for early screening of infections and, as a result, more effective management of the illness among flocks.
Aerodynamic Modeling of a Flying Wing Featuring Ludwig Prandtl’s Bell Spanload
Authors: Robb Caleb , Paul Ryan
Published: July 2023

This paper presents the aerodynamic modeling of a flying wing featuring Ludwig Prandtl’s bell spanload. The aerodynamic models are developed using a medium fidelity vortex-lattice method and using a Reynolds-Averaged Navier–Stokes computational fluid dynamics solution across a wide range of in-flow angle conditions. A methodology is developed to directly compare the spanwise force distributions from each method. Excellent agreement is seen in the prediction of spanwise inertial aerodynamic forces from each method, as well as in stability and control derivatives dominated by lift and moment contributions. The phenomenon of proverse yaw, caused by the twist distribution necessary to produce the bell spanload, is seen in the high and low-order analysis, with similar off-axis control power predicted.

Published: July 2023

The aerodynamic properties of rotor systems operating within low Reynolds number flow field conditions are profoundly influenced by their geometric and flight parameters. Precise estimation of optimal airfoil parameters at different angles of attack is indispensable for enhancing these aerodynamic properties. This study presents a technique for optimizing the airfoil parameters of a Mars helicopter by employing machine learning methods in conjunction with computational fluid dynamics (CFD) simulations, thereby circumventing the need for expensive experiments and simulations. The effectiveness of diverse machine learning algorithms for prediction is evaluated, and the resultant models are utilized for airfoil optimization. Ultimately, the aerodynamic properties of the optimized airfoil are experimentally validated. The experimental findings exhibit agreement with the simulated predictions, indicating the successful optimization of the aerodynamic properties. This research offers valuable insights into the influence of airfoil parameters on the aerodynamic properties of the Mars helicopter, along with guidance for airfoil optimization.
Impact of Partially Substituting Canola Meal with Solvent-Extracted Distillers Grain with Solubles as a Protein Source on Milk Production in a Commercial Holstein Dairy Herd

Published: July 2023

The removal of corn oil from dried distillers grains using solvent extraction allows a higher level of inclusion for solvent-extracted dried distillers grains with solubles (SDG) in rations and reduces the risk of milk fat depression in lactating Holstein dairy cows. The objective of this study was to evaluate the impact of substituting 70% of the canola meal (CM) with SDG on milk production and total mixed ration costs. A total of 1408 Holstein cows averaging 91 ± 49 days in milk were randomly enrolled to one of four dietary treatment groups: (1) primiparous control cows (PC) fed 13% CM and 0.21% urea; (2) primiparous SDG cows (PSDG) fed 4.2% CM, 8.8% SDG and 0.42% urea; (3) multiparous control cows (MC) with 13% CM and 0.21% urea; and (4) multiparous SDG cows (MSDG) with 4.1% CM, 8.6% SDG and 0.42% urea. The total mixed rations were formulated to be isonitrogenous. For the income over the feed costs from a control herd, the fed PC and MC’s total mixed rations and the fed PSDG and MSDG’s total mixed rations were compared. The milk yield, energy-corrected milk, milk fat yield, milk protein yield and milk protein % were lower in the PC cows compared to the PSDG cows. The MSDG cows scored lower in terms of the milk yield, milk protein yield and milk protein % and higher for the 3.5%-fat-corrected milk, milk fat yield and milk fat % compared to the MC cows. The total income, cost of dry matter and income over feed costs per cow/d were higher in the control vs. SDG simulated dairy herds. The control herd had a higher income over feed costs than the SDG herd because the average milk yield per cow/d was higher even though the SDG herd had a lower total mixed ration cost and higher milk fat production.

Published: July 2023

The aim of this study was to investigate the morphological traits and colony performance parameters of local honeybees of the Adıyaman province for future breeding programs. The study was carried out in 2019–2020; a total of 39 colonies were obtained from 13 apiaries in 5 districts, which represented local honeybees, and they were placed in an isolated area. At the same time, 835 worker bees representing local honeybees were assessed for 21 morphological features. There was a difference between the district groups according to the morphological traits (p < 0.05). In terms of the morphological characteristics of honeybees, the correct classification rate to their original groups was determined to be 65.1%. The difference between the district groups was statistically significant regarding the number of frames covered with bees, brood area, and hygienic behavior (p < 0.05). The average weight at the emergence of queens according to district groups and flight activity was found to be significant according to the periods (p < 0.01). As a result, homogeneous honeybees can be found in provinces when considering morphological characteristics. Although colony performance values are low, it is essential to protect the bees’ genetic material given their ability to adapt to arid climates and insufficient flora.
Inhibition of α-Amylase, α-Glucosidase, Pancreatic Lipase, 15-Lipooxygenase and Acetylcholinesterase Modulated by Polyphenolic Compounds, Organic Acids, and Carbohydrates of Prunus domestica Fruit
Authors: Rybak Martyna , Wojdyło Aneta
Published: July 2023

This work aimed to establish the content of phenolic compounds, carbohydrates, and organic acids and to determine their potential to inactivate α-amylase, α-glucosidase, pancreatic lipase, 15-lipoxygenase (15-LOX), acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE), and antioxidant activity (ABTSo+ and FRAP) in 43 Prunus domestica cultivars. We identified 20 phenolic compounds, including, in the order of abundance, polymeric procyanidins, flavan-3-ols, phenolic acids, flavonols, and anthocyanins. The total content of phenolic compounds varied depending on the cultivar and ranged from 343.75 to 1419 mg/100 g d.w. The cultivars of Ś2, Ś11, and Ś16 accumulated the greatest amounts of polyphenols, while in cvs. Ś42, Ś35, and Ś20 polyphenols were the least abundant. The highest antioxidant potential of 7.71 (ABTSo+) and 13.28 (FRAP) mmoL Trolox/100 g d.w. was confirmed for cv. Ś11. P. domestica fruits showed inhibitory activity toward α-amylase (2.63–61.53), α-glucosidase (0.19–24.07), pancreatic lipase (0.50–8.20), and lipoxygenase (15-LOX; 4.19–32.67), expressed as IC50 (mg/mL). The anti-AChE effect was stronger than the anti-BuChE one. Cv. Ś3 did not inhibit AChE activity, while cv. Ś35 did not inhibit BuChE. Thanks to the abundance of biologically active compounds, P. domestica offers several health-promoting benefits and may prevent many diseases. For these reasons, they are worth introducing into a daily diet.

Published: July 2023

Among the issues on which health directions focus, fall risk is one of major importance since it affects patients hospitalized in both acute and rehabilitative hospitals. In this context, few publications have proposed a managerial approach aimed at (a) investigating several factors related to falls and (b) trying to acquire more knowledge and comprehension when analyzing the data collected. Consequently, this paper pursues such objectives by investigating data related to falls (and the recurrence of falls) registered in a rehabilitation hospital within the years 2020 and 2021. A multidisciplinary team (clinical staff and engineers) registered 238 first falls, and descriptive statistics were used to analyze the fall-related anamnestic and clinical data. Then, appropriate statistical analyses were used to compare the same data—this time distinguishing fallers/recurrent fallers—and, again, descriptive statistics were used to analyze the consequences of falls. The statistical analyses allowed us to gain insights into the fall mechanisms, the main places in which falls took place, the impacts of drugs, and fall consequences (e.g., the potential extra costs for the hospital). Moreover, the Morse and Stratify risk tools, state of consciousness, and fall containment measures were proven to be statistically significant features for distinguishing fallers and recurrent fallers, and they may be further investigated to define more accurate preventive measures within rehabilitation hospitals.

Published: July 2023

Electrolytic aluminum operation accidents have caused great losses to countries and people. Therefore, taking two typical accidents of explosion and leakage in electrolytic aluminum production as the research object, the form of accident risk characterization was explored and a risk characterization visualization system was designed. Based on the methods of risk assessment and characterization, the likelihood and consequence of accidents were studied. The influencing factors of likelihood and a type of Euclidean distance formula were used to characterize the likelihood. The consequence portion was characterized by two components, with one being the failure degree determined by the accident and the other being the exposure degree of people and equipment. The intensity of event was used to characterize the failure degree and the spatial search model was used to characterize the exposure degree. Finally, the visual system of electrolytic aluminum operation accidents was established based on the risk characterization model.

Bimetallic Flower-like NiCoP Encapsulated in an N-Doped Carbon Shell with Enhanced Lithium Storage Properties
Authors: Tian Haoyu , Zhao Lingyu , Wang Linlin , Xia Zijie , Tan Wenqi , Jiao Zheng
Published: July 2023

It continues to be a challenge to design innovative NiCoP composite anode materials to further improve rate capacity. In this work, bimetallic flower-like NiCoP encapsulated in an N-doped carbon shell (designated as NiCoP@NC) as a high-rate capable anode material for lithium-ion batteries (LIBs) was successfully designed and synthesized. The novel structure design combines the advantages of flower-like NiCoP (core) and N-doped carbon (shell). Flower-like NiCoP offers numerous interface and redox reaction sites for improving lithium storage, while the N-doped carbon shell effectively buffers volume expansion and enhances electrical conductivity. The synergistic effect between NiCoP and the N-doped carbon shell proposes a marvelous high-rate capacity (320 mA h/g even at 5 A/g) and a good cycle life with high reversible capacity (369.8 mA h/g for 700 cycles at 3 A/g with 81% retention). An investigation of kinetics performance shows that the introduction of the N-doped carbon shell enhances the charge transfer, and the pseudocapacitive behavior dominates the rapid Li+ storage of the NiCoP@NC electrode.

There is no consensus on how to measure shoulder joint laxity and results reported in the literature are not well systematized for the available shoulder arthrometer devices. This systematic review aims to summarize the results of currently available shoulder arthrometers for measuring glenohumeral laxity in individuals with healthy or injured shoulders. Searches were conducted on the PubMed, EMBASE, and Web of Science databases to identify studies that measure glenohumeral laxity with arthrometer-assisted assessment. The mean and standard deviations of the laxity measurement from each study were compared based on the type of population and arthrometer used. Data were organized according to the testing characteristics. A total of 23 studies were included and comprised 1162 shoulders. Populations were divided into 401 healthy individuals, 278 athletes with asymptomatic shoulder, and 134 individuals with symptomatic shoulder. Sensors were the most used method for measuring glenohumeral laxity and stiffness. Most arthrometers applied an external force to the humeral head or superior humerus by a manual-assisted mechanism. Glenohumeral laxity and stiffness were mostly assessed in the sagittal plane. There is substantial heterogeneity in glenohumeral laxity values that is mostly related to the arthrometer used and the testing conditions. This variability can lead to inconsistent results and influence the diagnosis and treatment decision-making.
Endogenous Caulimovirids: Fossils, Zombies, and Living in Plant Genomes
Authors: Vassilieff Héléna , Geering Andrew D. W. , Choisne Nathalie , Teycheney Pierre-Yves , Maumus Florian
Published: July 2023

The Caulimoviridae is a family of double-stranded DNA viruses that infect plants. The genomes of most vascular plants contain endogenous caulimovirids (ECVs), a class of repetitive DNA elements that is abundant in some plant genomes, resulting from the integration of viral DNA in the chromosomes of germline cells during episodes of infection that have sometimes occurred millions of years ago. In this review, we reflect on 25 years of research on ECVs that has shown that members of the Caulimoviridae have occupied an unprecedented range of ecological niches over time and shed light on their diversity and macroevolution. We highlight gaps in knowledge and prospects of future research fueled by increased access to plant genome sequence data and new tools for genome annotation for addressing the extent, impact, and role of ECVs on plant biology and the origin and evolutionary trajectories of the Caulimoviridae.
ERK Signaling Pathway Is Constitutively Active in NT2D1 Non-Seminoma Cells and Its Inhibition Impairs Basal and HGF-Activated Cell Proliferation

c-MET/hepatocyte growth factor (HGF) system deregulation is a well-known feature of malignancy in several solid tumors, and for this reason this system and its pathway have been considered as potential targets for therapeutic purposes. In previous manuscripts we reported c-MET/HGF expression and the role in testicular germ cell tumors (TGCTs) derived cell lines. We demonstrated the key role of c-Src and phosphatidylinositol 3-kinase (PI3K)/AKT adaptors in the HGF-dependent malignant behavior of the embryonal carcinoma cell line NT2D1, finding that the inhibition of these onco-adaptor proteins abrogates HGF triggered responses such as proliferation, migration, and invasion. Expanding on these previous studies, herein we investigated the role of mitogen-activated protein kinase (MAPK)/extracellular signal regulated kinase (ERK) pathways in the HGF-dependent and HGF-independent NT2D1 cells biological responses. To inhibit MAPK/ERK pathways we chose a pharmacological approach, by using U0126 inhibitor, and we analyzed cell proliferation, collective migration, and chemotaxis. The administration of U0126 together with HGF reverts the HGF-dependent activation of cell proliferation but, surprisingly, does not exert the same effect on NT2D1 cell migration. In addition, we found that the use of U0126 alone significantly promotes the acquisition of NT2D1 «migrating phenotype», while collective migration of NT2D1 cells was stimulated. Notably, the inhibition of ERK activation in the absence of HGF stimulation resulted in the activation of the AKT-mediated pathway, and this let us speculate that the paradoxical effects obtained by using U0126, which are the increase of collective migration and the acquisition of partial epithelium–mesenchyme transition (pEMT), are the result of compensatory pathways activation. These data highlight how the specific response to pathway inhibitors, should be investigated in depth before setting up therapy.

The recent understanding of the etiology and pathology of dental caries has shifted its treatment from invasive drill and fill conventional strategies to noninvasive and/or minimally invasive approaches. Guided tissue regeneration (GTR) is a well-established therapeutic approach in medicine and periodontal and oral surgery. Recently, the concept of biomimetic regeneration has been further expanded to treat the loss of hard dental tissues. Self-assembling peptides have emerged as a promising biomaterial for biomimetic regeneration due to their ability to construct a protein scaffold in the body of early carious lesions and provide a matrix that promotes remineralization. This review article accompanies the development of self-assembling peptide P11-4 for the treatment of initial carious lesions. In vitro and in vivo studies on the safety, clinical applicability, and efficacy of P11-4 are discussed. Furthermore, different treatment options and potential areas of application are presented.

Liquid biopsy has progressed to its current use to diagnose and monitor cancer. Despite the recent advances in investigating cancer detection and diagnosis strategies, there is still a room for improvements in capturing CTCs. We developed an efficient CTC detection system by integrating gold nanoparticles with a microfluidic platform, which can achieve CTC capture within 120 min. Here, we report our development of a simple and effective way to isolate CTCs using antibodies attached on gold nanoparticles to the surface of a lateral filter array (LFA) microdevice. Our method was optimized using three pancreatic tumor cell lines, enabling the capture with high efficiency (90% ± 3.2%). The platform was further demonstrated for isolating CTCs from patients with metastatic pancreatic cancer. Our method and platform enables the production of functionalized, patterned surfaces that interact with tumor cells, enhancing the selective capture of CTCs for biological assays.

Yin Yang 1 (YY1) is a transcription factor that regulates epigenetic pathways and protein modifications. CP2c is a transcription factor that functions as an oncogene to regulate cell proliferation. YY1 is known to interact with CP2c to suppress CP2c’s transcriptional activity. This study aimed to investigate YY1 and CP2c expression in breast cancer and prognostic implications. In this study, YY1 and CP2c expression was evaluated using immunohistochemical staining, Western blot and RT-PCR assays. Of 491 patients with primary breast cancer, 138 patients showed YY1 overexpression. Luminal subtype and early stage were associated with overexpression (p < 0.001). After a median follow-up of 68 months, YY1 overexpression was found to be associated with a better prognosis (disease-free survival rates of 92.0% vs. 79.2%, p = 0.014). In Cox proportional hazards model, YY1 overexpression functioned as an independent prognostic factor after adjustment of hormone receptor/HER2 status and tumor size (hazard ratio of 0.50, 95% CI 0.26–0.98, p = 0.042). Quantitative analysis of YY1 and CP2c protein expression in tumors revealed a negative correlation between them. In conclusion, YY1 overexpression is a favorable prognostic biomarker in patients with breast cancer, and it has a negative correlation with CP2c at the protein level.

The present study examined the relationships between CT-derived muscle measurements, systemic inflammation, and survival in advanced cancer patients with good performance status (ECOG-PS 0/1). Data was collected prospectively from patients with advanced cancer undergoing anti-cancer therapy with palliative intent. The CT Sarcopenia score (CT-SS) was calculated by combining the CT-derived skeletal muscle index (SMI) and density (SMD). The systemic inflammatory status was determined using the modified Glasgow Prognostic Score (mGPS). The primary outcome of interest was overall survival (OS). Univariate and multivariate Cox regressions were used for survival analysis. Three hundred and seven patients met the inclusion criteria, out of which 62% (n = 109) were male and 47% (n = 144) were ≥65 years of age, while 38% (n = 118) were CT-SS ≥ 1 and 47% (n = 112) of patients with pre-study blood were inflamed (mGPS ≥ 1). The median survival from entry to the study was 11.1 months (1–68.1). On univariate analysis, cancer type (p < 0.05) and mGPS (p < 0.001) were significantly associated with OS. On multivariate analysis, only mGPS (p < 0.001) remained significantly associated with OS. In patients who were ECOG-PS 0, mGPS was significantly associated with CT-SS (p < 0.05). mGPS may dominate the prognostic value of CT-derived sarcopenia in good-performance-status patients with advanced cancer.

Published: July 2023

Although environmental and clean energy research has identified graphitic carbon nitride impregnated with reduced graphene oxide (rGO/g-C3N4) as a potential, efficient non-metallic photocatalyst, its efficacy against Contaminants of Emerging Concern (CECs) is relatively unknown. This study reports an optimized photocatalyst (response surface methodology, RSM) to remove the plasticizer and endocrine disruptor bisphenol A (BPA) from water. The synthetic procedure included sonication of prepared particles of g-C3N4 and graphite oxide (rGO), followed by reduction with hydrazine (24 h reflux), increasing specific surface areas, and improving synthesis reproducibility. In optimal conditions, the produced photocatalyst (50 mg L–1) removed 90% of BPA (100 mL, 100 μg L−1) in 90 min (30 min in the dark + 60 min irradiated) using a UV source (centered at 365 nm, 26 W) and exhibiting pseudo-first-order kinetics. For comparison purposes, under the same experimental conditions, pure g-C3N4 removed 50% of the BPA solution. Radical scavenging tests identified the superoxide radical as the main reactive oxygen species involved in the degradation. Two major degradation products were identified by mass spectrometry, both of them less ecotoxic than BPA to a variety of test organisms, according to in silico estimations (ECOSAR 2.0).

Published: July 2023

In the present study, enhanced wet oxidation of excess sludge from pharmaceutical wastewater by NaOH as an alkaline homogeneous catalyst was investigated. The experiments were carried out in a stainless-steel batch autoclave reactor. The highest volatile suspended solids (VSS) removal rate, 95.2%, was achieved at 260 °C within 60 min with an initial oxygen pressure of 1.0 MPa and NaOH 0.5 g·L−1. Simultaneously, the chemical oxygen demand (COD) removal rate of 57.3% was reached. The increase in volatile fatty acids (VFAs) demonstrated that the degradation of sludge was greatly accelerated by NaOH. Interestingly, the production of acetic acid, an intermediate by-product generated from the oxidation of organic compounds, increased significantly. These results illustrated that NaOH is a promising catalyst for the utilization of wet oxidation liquid of excess sludge as a carbon source for the treatment of wastewater.

Biogenic nanoparticles synthesized using medicinal plant extracts gain significant attention in the field of medicine. Current research reports about a simple, low cost, eco-friendly method to prepare silver nanoparticles (SNPs) using the leaf extract of Plectranthus amboinicus. UV-Visible spectroscopic analysis showed a surface plasmon resonance peak of synthesized SNPs at 410 nm. SNPs had an average hydrodynamic diameter of 111.5 nm with a zeta potential value of –19.4 mV. FTIR spectroscopic measurement revealed the characteristic peaks of SNPs. Electron microscopic analysis showed spherical-shaped nanoparticles. The potency of SNPs as a calorimetric biosensor was evaluated using its ability in detecting triethylamine (TEA)—a toxic organic solvent. A drastic change in color (pale yellow → dark black) was observed when an SNPs was treated with varying concentrations (0.01 to 0.3 mM) of TEA. SNPs showed antibacterial activity against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Furthermore, the biosynthesized SNPs possessed efficient anticancer activity against B16F10 murine melanoma cells, which was evaluated using MTT, scratch wound, and live/dead cell assays. These results prove that SNPs can serve as biosensors and antibacterial and anticancer agents for industrial and biomedical applications.

The purpose of this study was to radiographically and clinically assess, after six and twelve months, the additive effect of light-curable resin-modified glass ionomer (LCRMGI) varnish on preventive standard-of-care measures (sodium fluoride varnish, oral hygiene instructions, and dietary counseling) for the treatment of non-cavitated proximal carious lesions in primary molars. This prospective, split-mouth, randomized clinical trial recruited 5–8-year-old children with at least one pair of bilateral non-cavitated proximal carious lesions in the enamel or outer third of the dentin. The lesions were randomized into one of two groups: experimental (which received LCRMGI varnish with the preventive standard-of-care measures) or control (which received the preventive standard-of-care measure). A total of 47 out of 53 participants, with 70 out of 80 pairs, completed the study. Radiographically, lesions in the experimental groups were more likely to regress after six (OR = 3.25) and twelve months (OR = 2.67), but it was not statistically significant (p = 0.052 and p = 0.055, respectively). Clinically, the experimental group showed significantly higher regression rates than the control group after six and twelve months (p = 0.041 and p = 0.003, respectively). The LCRMGI varnish demonstrated promising potential as an adjuvant to preventive standard-of-care measures in promoting regression and inhibiting the progression of non-cavitated proximal carious lesions.
