Antidiabetic assessment; in vivo study of gold and core-shell silver-gold nanoparticles on streptozotocin-induced diabetic rats.

Recently, we have published a pioneering work on green biosynthesis and complete characterization of gold and core shell silver-gold nanoparticles (AuNPs and Ag@AuNPs). Herein, the so obtained nanoparticles are assessed for their antidiabetic activity in streptozotocin-induced diabetic rats. Thus, sixty-four male albino rats were divided into eight groups: control untreated; diabetic rats; diabetic rats received standard drug; diabetic rats received carrier only; diabetic rats received 0.

Anti-oxidant profiles and markers of oxidative stress in preterm neonates.

Background: Preterm birth is associated with an increased oxidant burden which places these infants at a higher risk of injury.

Aims: This prospective study aimed to assess levels of antioxidants and a marker of oxidative stress in preterm neonates.

Objectives: (i) To compare levels of anti-oxidants [vitamin A, vitamin E, catalase, total anti-oxidant status (TAS)] as well as malondialdehyde level (MDA) (a marker of lipid peroxidation) between preterm and full-term neonates; (ii) to determine changes in the values of measured vitamins at birth and at discharge among preterm neonates; and (iii) to compare levels of anti-oxidants with MDA levels in relation to complications of prematurity and outcome.

Role of Heme Oxygenase, Leptin, Coenzyme Q10 and Trace Elements in Pre-eclamptic Women.

The objective of this study to evaluate heme oxygenase (COHb), leptin and coenzyme Q10 (CoQ10) in pre-eclamptic women. Also Zinc, copper, Iron, total iron binding capacity, Ferritin and uric acid were assessed. 120 female subjects were included in this study.

Effect of aspartame on oxidative stress and monoamine neurotransmitter levels in lipopolysaccharide-treated mice.

This study aimed at investigating the effect of the sweetener aspartame on oxidative stress and brain monoamines in normal circumstances and after intraperitoneal (i.p.) administration of lipopolysaccharide (LPS; 100 μg/kg) in mice.

Novel synthesized aminosteroidal heterocycles intervention for inhibiting iron-induced oxidative stress.

The objective of this study was to elucidate the potential role of novel synthesized aminosteroidal heterocyclic compounds 2, 5, 9b and 10c against iron-induced oxidative stress with particular insight on erythrocyte ghosts in male rats. Chronic iron supplementation (3000 mg kg(-1) diet) for 6 weeks significantly increased plasma iron and ferritin levels. It also produced significant increase in plasma TNF-alpha and NO levels.
