Iron dyshomeostasis and time-course changes in iron-uptake systems and ferritin level in relation to pro-inflammatory microglia polarization in sepsis-induced encephalopathy.

Encephalopathy is a frequent and lethal consequence of sepsis. Recently, a growing body of evidence has provided important insights into the role of iron dyshomeostasis in the context of inflammation. The molecular mechanisms underlying iron dyshomeostasis and its relationship with macrophage phenotypes are largely unknown.

Neuroprotective effect of Crocus sativus against cerebral ischemia in rats.

The present study aimed to investigate the role of vascular endothelial growth factor (VEGF) in the neuroprotective effect of Crocus sativus (saffron) against cerebral ischemia/reperfusion injury (I/R) in rats. Four groups of a total forty I/R rats with 60-min occlusion followed by 48 h reperfusion or sham surgery were used. The sham and left-brain I/R control groups where treated with normal saline.

Antihypertensive Effects of Roselle-Olive Combination in L-NAME-Induced Hypertensive Rats.

This study aimed to evaluate the antihypertensive efficacy of a new combination therapy of and extracts (2 : 1; Roselle-Olive), using N(G)-nitro-L-arginine-methyl ester- (L-NAME-) induced hypertensive model. Rats received L-NAME (50 mg/kg/day, orally) for 4 weeks. Concurrent treatment with Roselle-Olive (500, 250, and 125 mg/kg/day for 4 weeks) resulted in a dose-dependent decrease in both systolic and diastolic blood pressure, reversed the L-NAME-induced suppression in serum nitric oxide (NO), and improved liver and kidney markers, lipid profile, and oxidative status.

Red yeast rice and coenzyme Q10 as safe alternatives to surmount atorvastatin-induced myopathy in hyperlipidemic rats.

Statins are the first line treatment for the management of hyperlipidemia. However, the primary adverse effect limiting their use is myopathy. This study examines the efficacy and safety of red yeast rice (RYR), a source of natural statins, as compared with atorvastatin, which is the most widely used synthetic statin.
