High-fat diet mouse model receiving L-glucose supplementations propagates liver injury.

Background And Aims: Limited data link manufactured sweeteners impact on metabolic dysfunction-associated steatotic liver disease (MASLD). We aimed to evaluate the effects of manufactured sugars (L-glucose) compared to natural sugars (D-glucose) on phenotype, molecular and metabolic changes in mice models fed with either regular diet (RD) or high fat diet (HFD).

Methods: C57BL/6 mice fed 16-weeks with either RD; 70% carbohydrate or HFD; 60% fat, with or without additional glucose (Glu, at 18% w/v) to drinking tap water at weeks 8-16; of either natural (D-Glu) or manufactured (L-Glu) sugars.

Osteopontin neutralization increases vitamin D receptors on NKT cells and ameliorates liver fibrosis by promoting their activity.

Introduction And Aims: Vitamin D has an immunomodulatory property influencing the activity of NKT cells. We aimed to study the impact of osteopontin (OPN), a key driver of fibrosis, on NKT cells' vitamin D receptor (VDR) and activity alterations.

Methods: Liver fibrosis was induced in BALB/C mice with carbon-tetrachloride (CCl) for 8 weeks with either vitamin D [100 ng/kg] or InVivoMAb anti-mouse OPN [100 μg/kg] 2X/week started at week-4 of CCl The liver injury profile of serum ALT, AST, and inflammatory cytokines were evaluated.

Evaluation of knowledge and attitudes regarding Alzheimer's disease and related dementia among medical students in Palestine: A cross-sectional study.

Introduction: Dementia, a major global health concern, is an acquired disorder that causes a progressive decline in cognitive abilities, affecting learning and memory, language, executive function, complex attention, perceptual-motor skills, and social cognition. Our study aims to evaluate the knowledge and attitudes regarding dementia and Alzheimer's disease among medical students.

Methods: This cross-sectional study was conducted among 393 medical students in Palestine from August 2023 to November 2023.

E-cigarette use among university students in Palestine: Prevalence, knowledge, and determinant factors.

Background: Recent reports indicated accelerated rates of e-cigarette use, especially among youth in various Middle Eastern countries, including Palestine. Nevertheless, little is known about knowledge, attitudes, and perceptions regarding this topic in Palestine. This study aimed to assess the prevalence of e-cigarette use among Palestinian university students, along with their knowledge, attitudes, and perceptions about e-cigarette use.

The diagnostic utility of FIB-4 as a non-invasive tool for liver fibrosis scoring among NAFLD patients: a retrospective cross-sectional study.

Objective: Liver biopsy is the gold standard method to evaluate patients with non-alcoholic fatty liver disease (NAFLD). However, due to its several limitations and complications, a reliable and non-invasive marker is required to assess liver fibrosis. In this study, we compared the performance of the FIB-4 index [based on age, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels and platelets count] with the Scheuer scoring system of liver biopsies to evaluate the diagnostic utility of FIB-4 among NAFLD patients with different liver fibrosis severities.
