The global problem of infectious and deadly diseases caused by microbes such as candida and mycobacteria presents major scientific and medical challenges. Antimicrobial drug resistance is a rapidly growing problem with potentially devastating consequences. Various pathogens can cause skin infections, such as bacteria, fungi, and parasites.

In general, ghrelin is known as one of the orexigenic hormones in mammals. On the other hand, it has been shown that ghrelin inhibits water intake, which appear to be inconsistent with its role in the feeding response. In this study, the effect of ghrelin on water intake was comprehensively addressed using conscious seawater-acclimated eels known as an experimental model for water drinking behaviour.

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 .

The subthalamic nucleus is thought to play a crucial role in controlling impulsive actions. Networked among the basal ganglia and receiving input from several cortical areas, the subthalamic nucleus is well positioned to influence action selection when faced with competing and conflicting action outcomes. The purpose of this study was to test the dissociable roles of the dorsal and ventral aspects of the subthalamic nucleus during action conflict in patients with Parkinson's disease undergoing intraoperative neurophysiological recording and to explore a potential mechanism for this inhibitory control.
