Methods: Nationwide cohort study among adults in Sweden, 2006-2018, was conducted. Register data on filled prescriptions, patient characteristics, co-medications, and DILI were linked.

Determinants of binge eating and its impact on indicators of obesity among Finnish adolescents - a cohort study.

Background: Binge eating, a type of disordered eating, is relatively common among youth and predisposes them to many adverse health outcomes. Diverse psychological and social factors may be associated with binge eating. The aim of this study was to examine child and parental psychosocial determinants of binge eating and its impact on indicators of obesity.

Stability of bilirubin and oxyhaemoglobin in cerebrospinal fluid.

Cerebrospinal fluid (CSF) is routinely investigated to diagnose subarachnoid haemorrhage (SAH) in cases with unclear neuroimaging findings. Using spectrophotometry, the levels of bilirubin and oxyhaemoglobin are analysed. This study investigates the stability for bilirubin and oxyhaemoglobin in CSF samples for up to 3 weeks measured with a spectrophotometer.

potentiation of tetracyclines in by RW01, a new cyclic peptide.

The pipeline for new drugs against multidrug-resistant remains limited, highlighting the urgent need for innovative treatments. New strategies, such as membrane-targeting molecules acting as adjuvants, aim to enhance antibiotic effectiveness and combat resistance. RW01, a cyclic peptide with low antimicrobial activity, was selected as an adjuvant to enhance drug efficacy through membrane permeabilization.

Transcription factors form a ternary complex with NIPBL/MAU2 to localize cohesin at enhancers.

While the cohesin complex is a key player in genome architecture, how it localizes to specific chromatin sites is not understood. Recently, we and others have proposed that direct interactions with transcription factors lead to the localization of the cohesin-loader complex (NIPBL/MAU2) within enhancers. Here, we identify two clusters of LxxLL motifs within the NIPBL sequence that regulate NIPBL dynamics, interactome, and NIPBL-dependent transcriptional programs.

Aldo-keto reductase family 1 member B10 prevents esophageal squamous cell carcinoma from reactive carbonyl species-induced cell death and promotes its progression.

Introduction: Chronic alcohol consumption and tobacco usage are major risk factors for esophageal squamous cell carcinoma (ESCC). Excessive tobacco and alcohol consumption lead to oxidative stress and the generation of reactive carbonyl species (RCS) which induce DNA damage and cell apoptosis. This phenomenon contributes to cell damage and carcinogenesis in various organs including ESCC.

Oral human papillomavirus infections in Zambian Rural and Urban residents-a community cross-sectional study.

Background: How common it is with the presence of human papillomavirus (HPV) in the healthy and diseased oral cavity is largely unknown for Africans. In this cross-sectional study we assessed the prevalence of oral HPV and the risk factors associated with HPV contraction including sexual practice in the urban and rural Zambian population.

Methods: Urban (N = 188) and rural (N = 211) Zambian adults aged 21 years and older living in Ndola and Mansa, respectively, were interviewed about demographical data, oral and coital sexual history and tobacco and alcohol use.

Physiological shedding and C-terminal proteolytic processing of TMEM106B.

Genetic variants in TMEM106B, coding for a transmembrane protein of unknown function, have been identified as critical genetic modulators in various neurodegenerative diseases with a strong effect in patients with frontotemporal degeneration. The luminal domain of TMEM106B can form amyloid-like fibrils upon proteolysis. Whether this luminal domain is generated under physiological conditions and which protease(s) are involved in shedding remain unclear.

Evaluating the need for standardised disease manifestation categories in patients infected with the tick-borne encephalitis virus: A Delphi panel.

Categorization systems for tick-borne encephalitis virus (TBEV) infection lack consistency in classifying disease severity. To evaluate the need for a standard, consensus-based categorisation system for TBEV infection across subtypes, we gathered an expert panel of clinicians and scientists with diverse expertise in TBEV infection. Consensus was sought using the Delphi technique, which consisted of 2 web-based survey questionnaires and a final, virtual, consensus-building exercise.

Time to Staphylococcus aureus Blood Culture Positivity as a risk marker of Infective Endocarditis: A Retrospective Cohort Study.

Background: Endocarditis occurs in approximately 10-15% of patients with Staphylococcus aureus bacteremia. Short time to positivity (TTP) in blood culture flasks has been linked to endocarditis in smaller studies. This study evaluated the association between TTP and endocarditis in S.

Synergistic Potential of Argentatins A and B to Improve 5-Fluorouracil Cytotoxicity in Colorectal Cancer Cell Models.

Colorectal cancer is the third most commonly diagnosed cancer worldwide and the second most common cause of cancer-related death in both men and women. Although a number of treatments are available to combat this malignancy, the antimetabolite 5-fluorouracil has been the cornerstone of therapy since its synthesis in the 1950s. Unfortunately, the prolonged use of 5-fluorouracil can lead to chemoresistance, which has prompted research into combination regimens to improve efficacy and quality of life and reduce resistance.

ADP-ribosyltransferase-based biocatalysis of nonhydrolyzable NAD+ analogs.

Enzyme promiscuity is the ability of an enzyme to catalyze an unexpected side reaction in addition to its main reaction. Here, we describe a biocatalytic process to produce nonhydrolyzable NAD+ analogs based on the ADP-ribosyltransferase activity of pertussis toxin PtxS1 subunit. First, in identical manner to normal catalysis, PtxS1 activates NAD+ to form the reactive oxocarbenium cation.

Methods: SARS-CoV-2 sequences in 2021-2022 from a nationwide study were included. The proportion of predominant lineages in Estonian regions and among travel-related cases was described by multinomial logistic regression.

Salvage Magnetic Resonance Imaging-guided Transurethral Ultrasound Ablation for Localized Radiorecurrent Prostate Cancer.

Background And Objective: Toxicity from local salvage therapy for radiorecurrent prostate cancer (PCa) remains a concern. This phase 2 study evaluates the outcomes of salvage magnetic resonance imaging (MRI)-guided transurethral ultrasound ablation (sTULSA).

Methods: Men with biochemically relapsed, biopsy-proven PCa following definitive radiotherapy underwent whole- or partial-gland sTULSA (NCT03350529).

Cryo-EM structures of the full-length human contactin-2.

Contactin-2 (CNTN2), an immunoglobulin cell adhesion molecule (IgCAM) expressed on the neural cell surface, regulates the formation of myelin sheaths, facilitates communication between neurons and axoglial cells, and coordinates the migration of neural cells. However, the assembly of full-length CNTN2 is still not fully elucidated. Here, we found that the full-length human CNTN2 forms a concentration-dependent homodimer.

Platelet characteristics in extremely preterm infants after fatty acid supplementation: a randomized controlled trial.

Background: Two risk factors for severe retinopathy of prematurity (ROP) in extremely preterm infants are thrombocytopenia and low levels of arachidonic acid (AA) and docosahexaenoic acid (DHA). To date, these risk factors have not been linked.

Method: Infants born < 28 weeks gestational age (GA) from 2016 to 2019 were randomized to postnatal enteral AA/DHA supplementation or standard care (controls).

MDSC: a new potential breakthrough in CAR-T therapy for solid tumors.

Chimeric antigen receptor T (CAR-T) cell therapy has shown remarkable success in hematologic malignancies but has encountered challenges in effectively treating solid tumors. One major obstacle is the presence of the immunosuppressive tumor microenvironment (TME), which is mainly built by myeloid-derived suppressor cells (MDSCs). Recent studies have shown that MDSCs have a detrimental effect on CAR-T cells due to their potent immunosuppressive capabilities.

Liver X Receptors and Inflammatory-Induced C/EBPβ Selectively Cooperate to Control CD38 Transcription.

Introduction: Macrophages abundantly express liver X receptors (LXRs), which are ligand-dependent transcription factors and sensors of several cholesterol metabolites. In response to agonists, LXRs promote the expression of key lipid homeostasis regulators. Cross talk between LXRs and inflammatory signals exists in a cell type- and gene-specific manner.

MUC17 is an essential small intestinal glycocalyx component that is disrupted in Crohn's disease.

Crohn's disease (CD) is the chronic inflammation of the terminal ileum and colon triggered by a dysregulated immune response to bacteria, but insights into specific molecular perturbations at the critical bacteria-epithelium interface are limited. Here we report that the membrane mucin MUC17 protected small intestinal enterocytes against commensal and pathogenic bacteria. In non-inflamed CD ileum, reduced MUC17 levels and a compromised glycocalyx barrier allowed recurrent bacterial contact with enterocytes.

PPARβ/δ upregulates the insulin receptor β subunit in skeletal muscle by reducing lysosomal activity and EphB4 levels.

Background: The increased degradation of the insulin receptor β subunit (InsRβ) in lysosomes contributes to the development of insulin resistance and type 2 diabetes mellitus. Endoplasmic reticulum (ER) stress contributes to insulin resistance through several mechanisms, including the reduction of InsRβ levels. Here, we examined how peroxisome proliferator-activated receptor (PPAR)β/δ regulates InsRβ levels in mouse skeletal muscle and C2C12 myotubes exposed to the ER stressor tunicamycin.

Enterococcus avium Infection After Liver Transplantation in Vietnam: A Case Report.

Background: The infectious complications are the most common and can be life-threatening to liver transplant recipients, in particular, within the first month after transplantation. Early diagnosis of these severe complications and accurate detection of causative etiologies are crucial for the choice of therapeutic strategies and management of liver transplants.

Case Report: We present a case report of a patient with a history of primary sclerosing cholangitis who underwent a liver transplantation (LT) from a living donor.

Endoscopic sleeve gastroplasty plus lifestyle intervention in patients with MASH: a multicentre, sham-controlled, randomized trial.

Metabolic dysfunction-associated steatohepatitis(MASH) is commonly seen in biopsy proven steatotic liver disease(SLD). Life-style intervention reaching a weight loss higher than 10% promotes MASH resolution, but this goal is only achieved by a small number of patients. Endoscopic sleeve gastroplasty(ESG) has recently emerged as a safe and effective option to promote weight loss in obese population.
