Using a combination of isothermal titration calorimetry and quantum and molecular dynamics calculations, we demonstrate that relatively soft anions have an affinity for hydrophobic concavity. The results are consistent with the anions remaining partially hydrated upon binding, and suggest a novel strategy for anion recognition.

Many important processes in cells depend on the transfer of protons through water wires embedded in transmembrane proteins. Herein, we have performed more than 55 μs all-atom simulations of the light-harvesting complex of a diatom, i.e.

The structural response of 1,2-dimyristoyl-glycero-3-phosphatidylcholine (DMPC)/water bilayers to addition and subsequent solvation of a small amphiphilic molecule - an anesthetic benzyl alcohol - was studied by means of solid-state NMR (H NMR, P NMR) spectroscopy and low-angle X-ray diffraction. The sites of binding of this solute molecule within the bilayer were determined - the solute was shown to partition between several sites in the bilayer and the equilibrium was shown to be dynamic and dependent on the level of hydration and temperature. At the same time, it was shown that solubilization of benzyl alcohol reached a solubility limit and was terminated when the ordering profile of DMPC hydrocarbon chains adopted finite limiting values throughout the whole chain.

Violation of the National Institute of Occupational Safety and Health (NIOSH) heat stress recommendations by exceeding the allowable wet bulb globe temperature (WBGT) for a given work intensity and work-rest ratio augments acute kidney injury (AKI) risk. Here we tested the hypothesis that exceeding the allowable work intensity at a given WBGT and work-rest ratio would also worsen AKI risk. Twelve healthy adults completed two NIOSH recommendation compliant trials and one noncompliant trial consisting of a 4 h (half workday) exposure.

The necrosis of pancreatic acinar cells is a key molecular event in the progression of acute pancreatitis (AP), with disturbances in mitochondrial energy metabolism considered to be a direct causative factor of acinar cell necrosis. Histidine triad nucleotide-binding protein 2 (HINT2) has been implicated in the development of various diseases, whereas its involvement in the progression of AP remains unclear. This study aims to investigate the role of HINT2 in AP.
