Rumen-protected zinc-methionine dietary inclusion alters dairy cow performances, and oxidative and inflammatory status under long-term environmental heat stress.

Dairy cows are susceptible to heat stress due to the levels of milk production and feed intake. Dietary supplemental amino acids, particularly rate-limiting amino acids, for example, methionine (Met), may alleviate the potential negative consequences. Zinc (Zn) is beneficial to the immune system and mammary gland development during heat stress.

Effect of oil extracts on inflammatory and oxidative stress markers in Behcet's disease: A randomized, double-blind, placebo-controlled clinical trial.

Objective: Behcet's disease (BD) is a chronic inflammatory disorder characterized by recurrent oral and genital aphthous ulcers, uveitis and skin lesions. Oxidative stress and inflammation have important role in the pathogenesis of BD. The aim of this study was to assess the effect of (NS) oil administration on malondialdehyde (MDA), total anti-oxidant capacity (TAC), tumor necrosis factor-α (TNF-α), IL-10 and high sensitivity C-reactive protein (hs- CRP) levels in patients with BD.

Short-term effects of lovastatin therapy on proteinuria of type 2 diabetic nephropathy: A clinical trial study.

Background: Diabetic nephropathy (DN) is characterized by albuminuria, hypertension, and a progressive decline in glomerular filtration rate. The 3-hydroxy-3-methylglutaryl coenzyme A is a well-known agent that is active in lowering total plasma and low-density lipoprotein cholesterol (LDL-C) levels in cases with hypercholesterolemia. Hence, in this study, proteinuria changes at the beginning and after the withdrawal of lovastatin in patients with type 2 DN (T2DN) were studied.

L-Carnitine supplementation improved clinical status without changing oxidative stress and lipid profile in women with knee osteoarthritis.

Considering the pathologic importance of oxidative stress and altered lipid metabolism in osteoarthritis (OA), this study aimed to investigate the effect of l-carnitine supplementation on oxidative stress, lipid profile, and clinical status in women with knee OA. We hypothesized that l-carnitine would improve clinical status by modulating serum oxidative stress and lipid profile. In this randomized double-blind, placebo-controlled trial, 72 overweight or obese women with mild to moderate knee OA were randomly allocated into 2 groups to receive 750 mg/d l-carnitine or placebo for 8 weeks.

Effects of sesame seed supplementation on lipid profile and oxidative stress biomarkers in patients with knee osteoarthritis.

Background: This study was designed to assess the effect of sesame seed on lipid profile and oxidative stress biomarkers in knee osteoarthritis (OA) patients.

Methods: Fifty patients with knee OA were allocated into two groups receiving 40 g of sesame seed daily along with standard medical therapy (n=25) or stan-dard treatment (n=25) for two months. Serum total antioxidant capacity, ma-londialdehyde (MDA) and lipid profile (total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, triglycerides) were measured.

Effect of treatment with omega-3 fatty acids on C-reactive protein and tumor necrosis factor-alfa in hemodialysis patients.

C-reactive protein (CRP), a strong independent risk marker of cardiovascular disease (CVD), and tumor necrosis factor-alfa (TNF-α), a known pro-inflammatory cytokine, are elevated and have damaging effects in patients with chronic renal failure (CRF). Omega-3 fatty acids play an important modulatory role in inflammatory responses. The aim of this study is to review the alterations in serum levels of TNF-α, CRP and other parameters caused by omega-3 supplementation in dialysis patients.

Correlation between the level of cholesteryl ester transfer protein in follicular fluid with fertilization rates in IVF/ ICSI cycles.

Background: Follicular fluid (FF) plays an important role in oocytes and embryo development, which may contribute to IVF/ICSI success rate.

Objective: The aim of this study was to investigate the correlation between cholesteryl ester transfer protein (CETP) level in FF and the success rate of IVF/ICSI.

Materials And Methods: In a cross-sectional study, FF samples, FF samples were obtained from 100 patients referred to Tabriz Alzahra Hospital.

Effect of omega-3 fatty acid on oxidative stress in patients on hemodialysis.

INTRODUCTION. Oxidative stress in patients with chronic kidney failure, particularly in hemodialysis patients, has been suggested to have a major role in the pathogenesis of atherosclerosis. We evaluated omega-3 fatty acids supplementation effects on oxidative and antioxidant factors in hemodialysis patients.

Effects of age increment and 36-week exercise training on antioxidant enzymes and apoptosis in rat heart tissue.

This study investigated the onset of age-related changes in the myocardial antioxidant enzymes and apoptosis and the vulnerability of the myocardium to oxidative stress following exercise training. Few studies have investigated the influence of the most prevalent life-prolonging strategy physical exercise, on the age increment alterations in the myocardial antioxidant enzymes and apoptosis at mid age and to determine whether exercise-induced antioxidant defense system could attenuate lipid peroxidation. Thirty six male Wistar rats were randomly assigned to exercise trained (n = 18) and sedentary (n = 18) groups.
