Background The intricate relationship between gut microbiota, sleep regulation, and mental health is a complex phenomenon that warrants further investigation. Research has shown that the gut microbiota plays a crucial role in modulating sleep patterns, mental health, and metabolic disorders. Methods This compilation of research includes a systematic review of the impact of gut microbiota on sleep regulation, particularly in conditions like diabetes and metabolic syndrome. Additionally, a study examines the sedative properties of Naoling Pian (NLP), a traditional Chinese medication, in treating insomnia. A review of the literature also explores the connection between the gut microbiota and psychiatric disorders. Results The systematic review reveals that the gut microbiota composition significantly affects sleep regulation, and that dietary choices can modulate microbial composition and metabolites, impacting sleep and metabolic syndrome. The study on NLP demonstrates its therapeutic benefits in treating insomnia, with effects similar to those of diazepam. The review of psychiatric disorders highlights the correlation between gut microbiota, sleep quality, and mental health, with specific bacteria linked to improved sleep quality in bipolar disorder. Conclusion These findings underscore the complex interplay between gut microbiota, sleep regulation, and mental health, and highlight potential therapeutic pathways for treating metabolic disorders, insomnia, and psychiatric disorders. Keywords: Gut microbiota, Insomnia, Mental health, Metabolic syndrome, Sleep regulation.

Rhabdomyosarcoma (RMS) is a predominantly pediatric soft-tissue cancer where the tumor cells exhibit characteristics of the developing skeletal muscle, and the two most common sub-types are embryonal and alveolar RMS. Elevated activation of the receptor tyrosine kinase (RTK) MET is frequent in RMS and is thought to cause increased tumor metastasis and lack of differentiation. However, the reasons underlying dysregulated MET expression and activation in RMS are not well understood. Therefore, we explored the role of Sprouty 2 (SPRY2), a modulator of RTK signaling, in regulating MET. We identify SPRY2 as a novel MET interactor that colocalizes with and binds MET in both embryonal and alveolar RMS. We find that depletion of SPRY2 leads to MET degradation, resulting in reduced migratory and clonogenic potential, and induction of differentiation in both embryonal and alveolar RMS, outcomes that are identical to depletion of MET. Activation of the ERK/MAPK pathway, known to be crucial for regulating cell migration and whose inhibition is required for myogenic differentiation, was downregulated upon depletion of MET or SPRY2. This provides a direct connection to the decreased migration and induction of differentiation upon depletion of MET or SPRY2. Thus, these data indicate that SPRY2 interacts with MET and stabilizes it in order to maintain signaling downstream of MET, which keeps the ERK/MAPK pathway active, resulting in metastatic potential and inhibition of differentiation in RMS. Our results identify a novel mechanism by which MET signaling is stabilized in RMS, and is a potential target for therapeutic intervention in RMS.

Approximately 50% of prostate cancer (PCa) patients harbor fusions involving the and genes. Despite this, tailored therapies targeting the fused gene, , remain undeveloped. Our study analyzed biopsy samples from two clinical trials assessing the efficacies of androgen receptor (AR) signaling inhibitors (ARSIs). The results revealed that promotes resistance to ARSIs and is associated with elevated levels of the glucocorticoid receptor (GR). Subsequent assays showed that GR directly interacts with tERG, alleviates allosteric autoinhibition and prevents chemotherapy-induced tERG degradation. In PCa models, either inhibiting GR or lowering cortisol levels suppressed tumor growth in tERG-positive models, but not in fusion-negative models. In addition, patient-derived fusion-positive xenografts displayed enhanced sensitivity to combined GR and AR inhibitors. Collectively, these findings highlight as a new biomarker and propose that simultaneous inhibition of GR and AR may specifically benefit -positine patients. However, GR stimulatory corticosteroid therapies may not be advisable for this patient subgroup.

EMT converts epithelial (E) phenotypes to invasive mesenchymal (M) states. However, analyses of circulating tumor cells (CTCs) indicated that biphenotypic (E+M) CTCs better correlate with metastasis. Similarly, investigations of murine tumors undergoing EMT concluded that early E+M states posses the highest metastatic potential. To explore this, we selected in animals with breast cancer CTCs having progressively increasing intravasation abilities. This revealed that downregulation of arrestin Arrdc4 associates with CTC aggressiveness. In xenografts, depleting Arrdc4 accelerated tumor progression, whereas overexpression hindered progression in immunocompetent, but not in immunocompromised mice. Mechanistically, high Arrdc44 suppresses glucose uptake and enhances gasdermin E, triggering pyroptosis a type of pro-inflammatory cell death. Consistently, Arrdc4's lowest levels characterize the most metastatic biphenotypic states. In patients, both epigenetic and chromosomal aberrations downregulate ARRDC4 and predict poor prognosis. In summary, the uncovered mechanism portrays pyroptosis of biphenotypic EMT cells as a rheostat of CTCs, which may resolve the controversy on the role played by EMT in metastasis.Competing Interest StatementThe authors have declared no competing interest.Footnotes* https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE280819* https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE277374

Purpose Infections caused by Acinetobacter baumannii, particularly those resistant to antibiotics such as carbapenem, have become a global health crisis with a significant mortality rate. Hospital‐acquired pneumonia (HAP) and ventilator‐associated pneumonia (VAP) resulting from the A. baumannii‐calcoaceticus (ABC) complex represent a major clinical challenge. This review aimed to understand the approval process, mechanism of action, therapeutic potential, and future implications of sulbactam‐durlobactam therapy (SUL‐DUR). Methods PubMed, Web of Science, EMBASE, Clinical trials. gov, ICTRP, and CENTRAL were searched for studies on SUL‐DUR for the treatment of hospital‐acquired pneumonia and ventilator‐associated pneumonia. Also, World Health Organization, U.S. Food and Drug Administration, and Centers for Disease Control and Prevention websites were searched for relevant information. Results SUL‐DUR, marketed as Xacduro, is a novel pharmaceutical combination that functions as a narrow‐spectrum parenterally administered antibiotic. Sulbactam acts as a β‐lactamase inhibitor, whereas durlobactam protects against degradation by A. baumannii enzymes. A phase 1 trial successfully established the safety and tolerability of SUL‐DUR in patients with normal and mild renal impairment. A phase 2 trial demonstrated the safety and tolerability of SUL‐DUR in a larger population with urinary tract infections. A phase 3 trial showed that SUL‐DUR was non‐inferior to colistin in terms of mortality in A. baumannii‐related VAP, HAP, and bacteremia. Conclusion The combination of sulbactam and durlobactam is a promising treatment option for HAP and VAP caused by ABC complex.

A transportation problem (TP) is built on the framework of supply-demand and cost parameters which are uncertain in nature. Neutrosophic numbers are capable of handling incomplete information. This paper introduces a new solution approach to optimize TPs with neutrosophic parameters based on a new ranking function. This function utilizes the attitudinal character of a basic unit-interval monotonic function inspired from the domain of continuous ordered weighted average operators. Ranking rules are established followed by defining a neutrosophic transportation problem. A solution methodology followed by solved numerical illustrates the efficiency of the proposed method. Conclusion and future directions summarize the work.

BackgroundIn the recent digital era, individuals with internet gaming disorder (IGD) have reported a much higher prevalence of poor sleep quality, perceived stress and suicidal behaviour. However, the underlying mechanisms for these psychological problems remain unknown.AimsThe primary aims of this study were to explore the mediating role of sleep quality on the relationship between IGD and the health outcomes of perceived stress and suicidal behaviour and to assess the prevalence and risk factors for IGD among medical students.MethodsA cross-sectional study enrolling 795 medical students from two medical colleges in a rural area of North India was conducted from April to May 2022. The study participants were chosen using a stratified random sampling approach. A self-administered questionnaire was used to collect data, including sociodemographic and personal information and gaming characteristics. The study also included the Gaming Disorder and Hazardous Gaming Scale, the Pittsburgh Sleep Quality Index, the Perceived Stress Scale-10 and the Suicide Behaviors Questionnaire–Revised to measure IGD, sleep quality, perceived stress and suicidal behaviour, respectively. Multiple logistic regression for the risk factors and Pearson’s correlation test for the relationship between variables were used. Hayes’ PROCESS macro for SPSS was employed to carry out mediation analysis.ResultsAmong the 348 gamers with a mean age of 21.03 (SD 3.27) years, the prevalence of IGD was 15.23% (95% confidence interval: 11.6% to 19.4%). In the correlational analysis, small to large (r: 0.32–0.72) significant relationships between scores of IGD and other health outcomes were established. The indirect effect (B=0.300) via sleep quality accounted for 30.62% of the total effect (B=0.982) of IGD on perceived stress (partially mediated), while sleep quality (B=0.174) accounted for 27.93% of the total effect (B=0.623) of IGD on suicidal behaviour (partially mediated). The factors of being male, living in a single-parent family, using the internet for other than academic purposes (1–3 hours and more than 3 hours/day), playing games for more than 3 hours/day and playing games with violent content were associated with IGD symptoms.ConclusionsUsing a dimensional measure, the results specified the relationship between IGD and perceived stress and suicidal behaviour by demonstrating that sleep quality meditated them. This modifiable mediating factor can be addressed by psychotherapy to mitigate the risk of perceived stress and suicidal behaviour among the future medical workforce.

For the quantitative determination of clopidogrel bisulphate in bulk and pharmaceutical dose forms, a straightforward, accurate, precise, and economical approach has been established. Methanol (a co-solvent) and 0.05 N acetic acid (a solvent) were used to create the standard and sample solutions. Area Under Curve (AUC), Zero order, and First order derivative are the three UV spectrophotometric methods that were developed. The zero order technique showed linearity at 270 nm over 10–100µg/ml with R² = 0.9992. The first derivative methodology yielded R² = 0.9996 at 244nm and 281nm (R² = 0.9987), whereas the AUC method yielded R² = 0.9994 at 265–275nm. For criteria including linearity, accuracy, precision, LOD, and LOQ, all techniques were validated in accordance with ICH guidelines. Precision studies showed that the percentage relative standard deviation was within acceptable boundaries. The results confirmed that all of the suggested methods are simple, sensitive, accurate, and suitable for routine drug screening in pharmaceutical formulations.

In the current SARS-CoV-2 outbreak, drug repositioning emerges as a promising approach to develop efficient therapeutics in comparison to drug development. The present investigation screened 130 US FDA-approved drugs including hypertension, cardiovascular diseases, respiratory tract infections (RTI), antibiotics and antiviral drugs for their inhibitory potential against SARS-CoV-2. The molecular drug targets against SARS-CoV-2 proteins were determined by the iGEMDOCK computational docking tool. The protein homology models were generated through SWISS Model workspace. The pharmacokinetics of all the ligands was determined by ADMET analysis. The study identified 15 potent drugs exhibiting significant inhibitory potential against SARS-CoV-2. Our investigation has identified possible repurposed drug candidates to improve the current modus operandi of the treatment given to COVID-19 patients.
