Microfabricated free standing, tuneable, porous microfilters from an epoxy based photoresist for effective bioseparation.

SU-8 is an epoxy-based, biocompatible thermosetting polymer, which has been utilized mainly to fabricate biomedical devices and scaffolds. In this study, thin, single-layered, freestanding tuneable porous SU-8 membranes were microfabricated and surface hydrophilized for efficient bioseparation. Unlike the previous thicker membranes of 200-300 μm, these thin SU-8 membranes of 50-60 μm thickness and pores with 6-10 μm diameter were fabricated and tested for blood-plasma separation, without any additional support structure.

Chemoprotective Effect of Sobatum against Lithium-Induced Oxidative Damage in Rats.

Lithium therapy mainly used in curing some psychiatric diseases responsible for numerous undesirable side effects on different organs in humans. The present study explores the beneficial effect of sobatum, a purified compound of Solanum trilobatum, on lithium carbonate (Li(2)CO(3))-induced multiple organ toxicity in rats. Li(2)CO(3) (150 mg/kg body weight) was administered orally in drinking water for a period of 30 days to induce toxicity in rats.

Influence of Vibrio parahaemolyticus MTCC 451 on the levels of ascorbic acid and histamine in Penaeus monodon (Fabricius).

Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed.
