Radiation is an important source of free radicals in living systems. Ionizing radiations such as γ-rays exert their biological effects through generation of reactive oxygen species and the resultant damage to DNA and cellular membranes. Several natural compounds, especially with antioxidant abilities are known to be radioprotective. Baicalein (5,6,7-trihydroxy-2-phenyl-4H-1-benzopyran-4-one), a...

the aim of the present study was to evaluate the antioxidant effects of aqueous fruit extract of ziziphusjujuba on ethanol-induced oxidative stress and to examine its protective effects on sperm motility and plasma membrane integrity of male wistar rats. adult male rats (n = 28) were divided into four equal groups: the first group served as untreated controls, the second group of rats was given...

Synaptosomal membrane order has been studied by analysis of light depolarization by fluorescent dyes intercalated within membranes following exposure to various environmental toxicants. Two probes were explored: 1,6-diphenyl-1,3,5-hexatriene (DPH), signaling predominantly from the lipid-rich membrane core, and 1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene (TMA-DPH), reporting from the ...

quence of the production of excess free radicals, such as reactive oxygen species, and provides marked damage to the structure and function of cell membranes in various tissues. Particularly, the brain is susceptible to free radical insults because it contains a high concentration of easily peroxidizable polyunsaturated fatty acids, and is not particularly enriched in protective antioxidant enz...

Anaerobic digestion of lipid-containing wastes for biogas production is often hampered by the inhibitory effect of long-chain fatty acids (LCFAs). In this study, the inhibitory effects of LCFAs (palmitic, stearic, and oleic acid) on biogas production as well as the protective effect of a membrane bioreactor (MBR) against LCFAs were examined in thermophilic batch digesters. The results showed th...

Erythrocytes from 14 patients with homozygous sickle cell anaemia were treated with the calcium ionophore A23187 to induce loss of cellular potassium and water. The dehydrated cells showed a decrease in filterability (loss of deformability) through pores of 5 micron diameter. Oxpentifylline and cetiedil citrate, which preserve erythrocyte cation and water content, had a significant (p less than...
