Mountain lions, Puma concolor, are widespread and adaptable carnivores. However, due to their large home ranges and long distance dispersals, they are strongly impacted by habitat fragmentation, which results in small and isolated populations. Genomic analyses play an important role in understanding and predicting the impacts of increased isolation of populations, such as decreased genetic diversity and increased levels of inbreeding.

Notably, in children, as well as volunteers challenged with ETEC, diarrheal severity is significantly increased in blood group A (bgA) individuals. EtpA, is a secreted glycoprotein adhesin that functions as a blood group A lectin to promote critical interactions between ETEC and blood group A glycans on intestinal epithelia for effective bacterial adhesion and toxin delivery.

Although ETEC are associated with long-term sequelae including malnutrition, the acute diarrheal illness is largely self-limited. Recent studies indicate that in addition to causing diarrhea, the ETEC heat-labile toxin (LT) modulates the expression of many genes in intestinal epithelia, including carcinoembryonic cell adhesion molecules (CEACAMs) which ETEC exploit as receptors, enabling toxin delivery.

It is unclear if wearing ankle compression garments (CGs) can enhance balance control and time to fatigue in those athletes. The purpose of this study was to examine the impact of ankle CGs on both time to fatigue and single-leg balance.
