Acidification is a key component of digestion throughout metazoans. The gut digestive fluid of many invertebrates is acidified by the vesicular-type H+-ATPase (VHA). In contrast, vertebrates generate acidic gut fluids using the gastric H+/K+-ATPase (HKA); an evolutionary innovation linked with the appearance of a true stomach that greatly improves digestion, absorption, and immune function.

Many chronic medical conditions that can result from poor nutrition are more prevalent in the incarcerated population than in the general population. With the increasing prevalence of chronic medical conditions and limited knowledge on foods accessible to the population, this study assessed the 4-week menu fed to all incarcerated males at state-run facilities in Alabama. Compared with the Acceptable Macronutrient Distribution Range for the average incarcerated male, the percentage of energy from total fat, saturated fat, sodium, and cholesterol exceeded the recommendation.

The emerging prevalence of antimicrobial resistance demands cutting-edge therapeutic agents to treat bacterial infections. We present a synthetic strategy to construct sequence-defined oligomers (SDOs) by using dithiocarbamate (DTC). The antibacterial activity of the synthesized library of SDOs was studied using a Gram-positive and a Gram-negative .

Despite its importance in understanding biology and computer-aided drug discovery, the accurate prediction of protein ionization states remains a formidable challenge. Physics-based approaches struggle to capture the small, competing contributions in the complex protein environment, while machine learning (ML) is hampered by the scarcity of experimental data. Here, we report the development of p ML (KaML) models based on decision trees and graph attention networks (GAT), exploiting physicochemical understanding and a new experiment p database (PKAD-3) enriched with highly shifted p's.

Gsx2 is a homeodomain transcription factor critical for development of the ventral telencephalon and hindbrain of the mouse. Loss of Gsx2 function results in severe basal ganglia dysgenesis as well as defects in the nucleus tractus solitarius (nTS) of the hindbrain together with respiratory failure at birth. De Mori et al.
