We studied the association of physical activity and adherence to the Mediterranean diet, in total antioxidant capacity (TAC). A random sample of 1514 men and 1528 women was selected from Attica region. Physical activity was assessed with a translated version of the validated "International Physical Activity Questionnaire" (iPAQ), and dietary intake through a validated Food Frequency Questionnai...

In the present study, we aimed to provide information on the serum content of sialic acids (TSA, LBSA, and PBSA), total antioxidant capacity (TAC), and adenosine deaminase (ADA) activity in cattle affected with naturally acquired theileriosis and anaplasmosis. A total of 55 Holstein cattle, comprising of 15 clinically healthy control animals, 20 cattle with theileriosis, and 20 with anaplasmosi...

introduction: toxic effects of pesticides are commonly associated with reactive oxygen species damage and pentoxifylline a phosphodiesterase inhibitor is a drug well known for antioxidant properties. the purpose of this study was to evaluate the oxidative damages following a subacute exposure to malathion, an organophosphorus insecticide and pentoxifylline's ability to counteract these eff...

occurrenceofoxidative stress (os) following in vitro culture is inescapable. therefore, the aim of the present study was to determine the efficacy of coenzyme q 10 (coq 10 ) supplementation medium on developments and total antioxidant capacity (tac) of mouse vitrified pre-antral follicles. fresh and vitrified-warmed isolated preantral follicles from ovaries of 14-16 day s -old mice were cultured...

In their nice study on serum total antioxidant capacity (TAC) in sepsis [1] Chuang and coworkers have demonstrated an increase in TAC that was directly correlated to severity of illness and poor outcome, and to increasing levels of serum uric acid (UA). Although the increase in TAC might be interpreted as an extreme protective attempt against overwhelming inflammation, this must still be proved...

Cocoa is a rich source of flavonoids, mainly (-)-epicatechin, (+)-catechin, and procyanidins. This article reports the effect of continuous cocoa intake on antioxidant capacity in plasma and tissues, including lymphoid organs and liver, from young rats. Weaned Wistar rats received natural cocoa (4% or 10% food intake) for three weeks, corresponding to their infancy. Flavonoid absorption was con...

Introduction : Osteoarthritis (OA) refers to progressive degeneration of articular cartilage with gradual painful disorganisation of the joint. Lipid peroxidation mediated by free radicals is the major mechanism of cell membrane destruction and cell damage. It is a known that there is an increased oxidative stress in OA and very little is known about the relation between the pain and decreased ...

OBJECTIVE Human milk (HM) has antioxidant constituents which protect newborns against oxidative damage. We aimed to evaluate whether maternal consumption of herbal tea containing fenugreek had any effects on global oxidant and antioxidant capacity of HM. METHODS Volunteer mothers 18-35 years of age without any antenatal or perinatal risk factors were randomly assigned to receive galactagogue ...

BACKGROUND Total antioxidant capacity (TAC) provides an assessment of antioxidant activity and synergistic interactions of redox molecules in foods and plasma. OBJECTIVE We investigated the validity and reproducibility of food-frequency questionnaire (FFQ)-based TAC estimates assessed by oxygen radical absorbance capacity (ORAC), total radical-trapping antioxidant parameters (TRAP), and ferri...

BACKGROUND Dental caries is a major problem in preschool children. The contribution of saliva in providing defense during caries process is of primary importance. pH buffer capacity through bicarbonate, phosphate and protein buffer systems have universal acceptance as a caries defense mechanism. Antioxidant capacity of saliva can constitute a first line of defense against chronic degenerative d...
