BACKGROUND To evaluate the effect of dental amalgam and composite restorations on total antioxidant capacity (TAC) and calcium (Ca) ion concentration of unstimulated saliva. MATERIAL AND METHODS Forty-eight children aged 6-10 years selected and divided into three groups of sixteen (8 males, 8 females). In group A and B, samples consisted of two class II dental composite or amalgam restoration...

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). It is characterized by loss of myelin, the fatty tissue that surrounds and protects nerve fibres allowing them to conduct electrical impulses. Recent data indicate that oxidative stress (OS) plays a major role in the pathogenesis of multiple sclerosis (MS). The aim of this study was to estimate level ...

Epidemiological studies have demonstrated that many antioxidants and the total antioxidant capacity (TAC) of the diet may protect against cancers and cardiovascular disease. Common fruits and vegetables are good sources of antioxidants, although in some Mediterranean areas traditional wild greens are responsible for a significant percentage of total dietary antioxidant intake. In the European P...

Three different apple-carrot juice blends (60:40, 75:25 and 90:10, v/v) were prepared and treated with ultrasound with comparison to the conventional thermal pasteurization. Total aerobic viable count (TAC) were significantly lower in juice blends with lower pH (apple-carrot ratio of 90:10, v/v) than the blends with higher pH after one month storage at 4 ̊C. TAC were similar in ultrasound-treate...

Total Antioxidant Capacity (TAC) is a biomarker often used in order to investigate oxidative stress in many pathological conditions. Saliva and urine can be collected noninvasively and represent attractive diagnostic fluids for detecting biomarkers of various pathological conditions. The reviewed case-control and intervention studies that measured salivary or urinary TAC revealed that diseases,...

BACKGROUND Recent studies have shown that oxidative stress (OS) is the most important indicator in the pathogenesis of Alzheimer's disease (AD), but the results in previous studies are conflicting. This study aimed to assess the plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as DNA oxidative damage marker and total antioxidant capacity (TAC) in patients with AD versus control group. ME...

Background: Varicoceles are the abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis. Recently, studies evaluating the role of oxidative stress in male infertility have shown that infertile men with varicocele have elevated levels of sperm and testicular tissue-derived reactive oxygen species (ROS). Therefore current study was designed to evaluate prot...

BACKGROUND Premenstrual syndrome (PMS) is one of the important health problems with high incidence in young women. The exact cause of this syndrome is not clear and some theories have been declared from hormonal factors to nutritional disorders. OBJECTIVE We investigated the correlation between serum zinc and antioxidant status with PMS. MATERIALS AND METHODS In this case-control study, for...

Objective: Pili (Canarium ovatum, Engl.) pomace is an underutilized agricultural waste that possesses great potential to be regarded as a functional food ingredient. The aim of this study was to measure the polyphenol content and antioxidant activity of pili pomace drink and determine the influence of heating on these parameters. Moreover, it sought to assess the acute effects of thermally proc...

This study was conducted to assess the effect of ginger supplementation on malondialdehyde (MDA) level, as an oxidative stress marker, and total antioxidant capacity (TAC) in broiler chicks. Two hundred male 1-day-old chicks were assigned randomly to four dietary treatments (basal diet as control group and basal diet containing 2.5, 5.0 and 7.5 g/kg ginger, respectively), with five replicates a...
