The structure, ultrastructure and osmoregulatory function of the branchial chamber were investigated in Palaemon elegans (Rathke, 1837) by light microscope, electron microscope and immunohistochemistry methods, respectively. Each chamber possesses a branchiostegite, 3 epipodites and 8 phyllobranchiate gills. The lamellae are attached along the two outer surfaces of the triangular gill axis. Ult...

BACKGROUND: Glutamate toxicity is involved in several neurodegenerative conditions, including Alzheimer’s disease. OBJECTIVE: The study aims to investigate the neuroprotective efficacy of ethanol extract Hibiscus sabdariffa calyces (HS) against glutamate-induced HT-22 cells and anti-aging property Caenorhabditis elegans. METHODS: were pre-treated with HS followed by glutamate evaluated for effe...

A chitinase-producing bacteria was locally isolated from rhinoceros beetle (Oryctes rhinoceros) larvae gut discovered in mushroom compost. strain selected the source and labeled as RBLG1. It identified using 16s rDNAsequencing has strong homology to Bacillus cereus. Chitinase produced RBLG1 purified ammonium sulfate precipitation, ion exchange chromatography, gel filtration. The chitinase shows...
