is one of the most abundant and important butyrate-producing human gut anaerobic bacteria that plays an important role in maintaining health and is a potential next-generation probiotic. We investigated the pangenome of 16 distinct strains, isolated over several decades, identifying local and time-specific adaptations. More than 50% of the genes in each individual strain were assigned to the core genome, and 77% of the cloud genes were unique to individual strains, revealing the high level of genome conservation.

Nutritional programming is a manipulation of fetal and neonatal development through maternal feeding. In humans and pigs, maternal yeast supplementation was demonstrated as a promising approach to positively to modulate newborns' health. This study aimed to investigate the effects of var.

Background: A high proportion of survivors of Ebola virus disease (EVD) have post-acute sequelae of EVD (PASE), but the relationship between inflammation and PASE pathogenesis is poorly understood. This study tests the hypothesis that inflammation is associated with PASE among survivors with and without viral RNA shedding in the semen.

Methods: This was a case-control study nested in a longitudinal cohort that recruited confirmed survivors of EVD and their uninfected contacts from the 2013-16 EVD epidemic in Liberia, starting on June 1, 2015.

Protein evolution has shaped enzymes that maintain stability and function across diverse thermal environments. While sequence variation, thermal stability and conformational dynamics are known to influence an enzyme's thermal adaptation, how these factors collectively govern stability and function across diverse temperatures remains unresolved. Cytosolic malate dehydrogenase (cMDH), a citric acid cycle enzyme, is an ideal model for studying these mechanisms due to its temperature-sensitive flexibility and broad presence in species from diverse thermal environments.

Alertness is a necessity for well-being and performance, and sleepiness is associated with cognitive and functional impairments that can have a negative impact on performance, health, mood, safety, and quality of life. In severe cases, sleepiness can lead to debilitation, injury, or death. Sleepiness is a marker of insufficient sleep and is the major patient-reported symptom associated with disorders of sleep and wakefulness such as narcolepsy and obstructive sleep apnea.
