The study investigated body condition score (BCS), hematological parameters, metabolic profile indicators, total oxidant-antioxidant status, and milk yield (MY) of cows in non-funded (NF) funded (F+) dairy farms by the European Union funds (under Instrument for Pre-accession Assistance Rural Development-IPARD) to support rural development. Sixty multiparous Holstein (110 209 days lactation) fro...

objective:diabetes mellitus is a common metabolic disorder that is one of the important factors in the etiology of injuries oxidant know the purpose the aim of the present study, was the effect of swimming training with arbutin on total oxidant status (tos) and total antioxidant status(tas) the kidney tissue of alloxan-induced diabetic rats.methods: for this purpose, 42 male wistar rats with an...

Background: Breast milk is a natural food that contains all the fluids, energy, and nutrients necessary for optimum growth development of newborns. Smoking public health problem has harmful effects on mother baby. This study aimed to examine association exposure smoking with total oxidant status (TOS) antioxidant (TAS) in breast milk.

Natural flavonoids such as quercetin, (+)catechin and rutin as well as four methoxylated derivatives of quercetin used as models were investigated to elucidate their impact on the oxidant and antioxidant status of human red blood cells (RBCs). The impact of these compounds against metal toxicity was studied as well as their antiradical activities with DPPH assay. Antihemolytic experiments were ...

Reactive oxygen species not only cause damage but also have a physiological role in the protection against pathogens and in cell signalling. Mitochondrial nutrients, such as coenzyme Q10 and α-lipoic acid, beside their acknowledged antioxidant activities, show interesting features in relation to their redox state and consequent biological activity. In this study, we tested whether oral suppleme...

Oxidative stress has been implicated as a causal factor in the aging process of the heart and other tissues. To determine the extent of age-related myocardial oxidative stress, oxidant production, antioxidant status, and oxidative DNA damage were measured in hearts of young (2 months) and old (28 months) male Fischer 344 rats. Cardiac myocytes isolated from old rats showed a nearly threefold in...

OBJECTIVE Lipoic acid (LA) is an effective anti-oxidant agent that can scavenge free radicals in biological systems. The aim of this research was to study the probable protective effect of LA in spinal ischemic/reperfusion (I/R) injury. MATERIALS AND METHODS Thirty male Wistar rats, weighing 230-285 g, were assigned randomly into 3 groups (10 animals in each group): sham spinal I/R, and spina...

OBJECTIVE Ischemia causes reversible or irreversible cell or tissue damage and reperfusion can exaggerate cellular damage. Microvascular dysfunction is induced and causes enhanced fluid filtration in capillaries. At the acute phase of reperfusion more oxygen radicals are activated. Nesfatin-1 protects brain against oxidative damage and heart against ischemia/reperfusion damage. In our study, we...

Viruses, including herpes viruses, can alter oxidative balance by either increasing the formation of free radicals or inhibiting synthesis of enzymes involved in oxidative defense within host cells. This study examined the occurrence of oxidative and antioxidative balance in cows naturally infected with bovine herpesvirus type 1 (BHV-1) under field conditions. Clinical history indicated that co...
