Carolacton, a naturally occurring MTHFD1 inhibitor, exhibits potent inhibitory activity against various RNA viruses including SARS-CoV-2. Herein, we present a concise total synthesis of carolacton, featuring the Krische allylation, Marshall coupling, NHK coupling, and RCM reaction as key elements. Additionally, we have synthesized three simplified carolacton analogues, one of which, namely, 14-demethyl-carolacton, exhibited notable antiviral activity. The present work paves the way for further exploration of the therapeutic potential of carolacton and its analogues.

Human skeletal muscle comprises slow-twitch (type I) and fast-twitch (type II) fibers. Fiber type-specific analyses often require manual isolation of fibers, necessitating effective tissue preservation. While freeze-drying remains the standard, alternative preservation methods such as RNAlater and RNAlater-ICE are increasingly used.

This study investigated the effects of fermentable fiber and polyphenol supplementation on mood and cognition following rapid ascent to simulated 4300 m. Healthy adults (n = 13, 21 ± 3 years) participated in a randomized, placebo-controlled crossover study consisting of three, 2-week phases separated by ≥1 week. Food products containing the fiber and polyphenol supplement or placebo were consumed during each phase.

Background: Sub-Saharan Africa (SSA) bears the highest global burden of cervical cancer. Living with the disease is a complex experience, leading to significant changes across various biopsychosocial dimensions, which in turn affect the quality of life of affected women.
Aims: This review aimed to synthesize available scientific evidence on the life experiences of women diagnosed with cervical cancer in SSA in order to generate valuable insights into the care of the affected population.

A 79-year-old Chinese man was referred for nephrotic syndrome (proteinuria 4.4 g/day). In blood tests, serum high-density lipoprotein (HDL) cholesterol was undetectable, and the esterified cholesterol to total cholesterol ratio was very low.

Objectives: This study evaluated the effects of proximal core training on biomechanical risk factors and strength parameters in individuals at high risk of anterior cruciate ligament (ACL) injury (specifically: those exhibiting pathological movement patterns, neuromuscular deficits or biomechanical risk factors) and compared direct versus indirect interventions. We hypothesised that targeted training enhances dynamic knee stabilisation and hip control during high-risk manoeuvres, with direct approaches providing superior biomechanical benefits through neuromuscular control optimisation.
Design: Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach.
