Distinct network patterns emerge from Cartesian and XOR epistasis models: a comparative network science analysis.

Background: Epistasis, the phenomenon where the effect of one gene (or variant) is masked or modified by one or more other genes, significantly contributes to the phenotypic variance of complex traits. Traditionally, epistasis has been modeled using the Cartesian epistatic model, a multiplicative approach based on standard statistical regression. However, a recent study investigating epistasis in obesity-related traits has identified potential limitations of the Cartesian epistatic model, revealing that it likely only detects a fraction of the genetic interactions occurring in natural systems.

Investigating context-specific sedentary behaviours and cardiometabolic health in college-based young adults (CONTEXT-SB): a protocol for a longitudinal observational study.

Background: Sedentary behaviour (SB) is detrimental to cardiometabolic disease (CMD) risk, which can begin in young adulthood. To devise effective SB-CMD interventions in young adults, it is important to understand which context-specific SB (CS-SB) are most detrimental for CMD risk, the lifestyle behaviours that cluster with CS-SBs and the socioecological predictors of CS-SB.

Methods And Analysis: This longitudinal observational study will recruit 500 college-aged (18-24 years) individuals.

Don't Sleep on Sleep: A Case Report from a Division I Heptathlete.

A female NCAA Division I track athlete experienced non-localized shin pain midway through her first season, which was diagnosed as medial tibial stress syndrome. Treatments included strengthening and range of motion exercises, reduced training volume, and pain control modalities, but symptoms worsened. It was revealed she had been suffering from severe sleep deprivation (<3 hours/night) contributing to bilateral tibial and fibular stress reactions.

Tuft cells transdifferentiate to neural-like progenitor cells in the progression of pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDA) is partly initiated through the transdifferentiation of acinar cells to metaplasia, which progresses to neoplasia and cancer. Tuft cells (TCs) are chemosensory cells not found in the normal pancreas but arise in cancer precursor lesions and diminish during progression to carcinoma. These metaplastic TCs (mTCs) suppress tumor progression through communication with the tumor microenvironment, but their fate during progression is unknown.
