Background: Scientific research has confirmed the biological activity of resveratrol, which includes its antioxidant, anti-inflammatory, cardioprotective and anticancer properties. There is no known interaction between a static magnetic field resveratrol that can modulate resveratrol’s effect on cells. Thus, main aim our was to assess co-exposure oxidation–reduction homeostasis C32 Colo829 mela...

The focus in antioxidant research is on enzyme derivative investigations. Extracellular superoxide dismutase (EC-SOD) is of particular interest, as it demonstrates in vivo the protective action against development of atherosclerosis, hypertension, heart failure, diabetes mellitus. The reliable association of coronary artery disease with decreased level of heparin-released EC-SOD was established...

Cadmium (Cd) brings a devastating health hazard to human being as a serious consequence of agricultural and environmental contamination. We demonstrated the protective effect of silicon (Si) on cadmium (Cd)-stressed rapeseed (Brassica napus L. cv. BINA Sharisha 3) plants through regulation of antioxidant defense and glyoxalase systems. Twelve-day-old seedlings were exposed to Cd stress (0.5 and...

The aim was to estimate association of the oxidative stress with the occurrence of age-related macular degeneration (AMD). The activities of erythrocyte antioxidant enzymes: superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) and additionally serum total antioxidant status (TAS) were used as indicators of the oxidative stress level. 57 AMD patients (32 early and 25 late ...

The study deals with activity of three antioxidant enzymes, copper, zinc-superoxide dismutase (CuZnSOD), manganese superoxide dismutase (MnSOD), catalase (CAT) in hippocampus of rats, following the exposure to single chronic (individual housing or forced swimming) and acute (immobilization or cold) stress, as well as to combined chronic/acute stress. In addition, plasma noradrenaline (NA) and a...

The present study evaluated the effects of hyperthyroid state on lipid peroxidation and antioxidant enzymes in the crude (CF), post nuclear (PNF) and mitochondrial fractions (MF) of the fish liver. The in vivo injection of T3 (200ng) did not change the lipid peroxidation products, malondialdehyde (MDA) and conjugated dienes (CD), while actinomycin D (10microg), a potent mRNA inhibitor when admi...

the aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. according to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...

Free radical-induced oxidative damage occurs rapidly and is of primary importance during the secondary pathophysiological cascades of traumatic brain injury (TBI). Hydroxysafflor yellow A (HSYA) is a constituent of the flower petals of Carthamus tinctorius (safflower) and may represent a potential therapeutic strategy to improve outcomes following TBI. The present study aimed to identify HSYA i...

Bryophytes are poikilohydric organisms that can be used as model plants to study desiccation tolerance mechanisms. The main objective of this was examine the activities antioxidant enzymes ascorbate peroxidase (APX), catalase (CAT) and guaiacol (POD) in rehydrated desiccated states Syntrichia ruralis (Hedw.) Web. & Mohr. from two slopes, one North-east (NE) South-west (SW) facing collected ...
