Background: The emergence of microbial resistance to conventional antibiotics and the environmental impact of chemical pesticides necessitates the search for alternative and sustainable solutions.This study explores the utilization of the dried biomass of the red algae Hypnea pannosa to synthesize silver nanoparticles (AgNPs) using a green and eco-
Prolonged Intracellular Na+ Dynamics Govern Electrical Activity in Accessory Olfactory Bulb Mitral Cells.
Persistent activity has been reported in many brain areas and is hypothesized to mediate working memory and emotional brain states and to rely upon network or biophysical feedback.Here, we demonstrate a novel mechanism by which persistent neuronal activity can be generated without feedback, relying instead on the slow removal of Na+ from neurons fo
Ammonia Affects Astroglial Proliferation in Culture.
Primary cultures of rat astroglial cells were exposed to 1, 3 and 5 mM NH4Cl for up to 10 days.Dose- and time-dependent reductions in cell numbers were seen, plus an increase in the proportion of cells in the S phase.The DNA content was reduced in the treated cells, and BrdU incorporation diminished.However, neither ammonia nor ammonia plus Knife S
