Background and aims. Cigarette smoke can induce oral cancer by its free radicals and oxidative damage. Salivary anti-oxidants system is believed to have an important role in defense mechanisms against oxidative stress. This study was compared total antioxidant capacity (TAoC) of saliva in smokers and nonsmokers. Materials and methods . In this cross-sectional study, 30 male smokers with mean ag...

INTRODUCTION There is a pressing need to better understand the complex biochemical pathways that lead to the pathogenesis of obesity. Increased oxidative stress and decreased antioxidant capacity have been identified to be associated with obesity. Therefore, the objectives of this study were to determine the plasma total antioxidant capacity (TAC) levels of Malaysian subjects and to evaluate it...

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 ...

Aim: To assess and correlate the level of stress to the total anti­ oxidant capacity of saliva of university exam­going students study­ ing at KLE Vishwanath Katti Institute of Dental Sciences, Belagavi, Karnataka, India, on the day of examination (stressed condition) and in the postexamination period (nonstressed condition). Materials and methods: Saliva samples of 30 students evaluated by the...

OBJECTIVE Dental caries is one of the most common infectious diseases worldwide. Saliva has many functions in the oral cavity and is the first line defense against dental caries. Oxidative stress can affect initiation and progression of many inflammatory and infectious diseases such as dental caries. Thus the aim of this study was to evaluate the relationship between total antioxidant capacity ...

The antioxidant capacity and antioxidant constituents of two filamentous fungi (Acremonium charticola and Rhizopus oryzae) isolated from the Indonesian fermented dried cassava (gathot) were evaluated in the present study. The antioxidant capacity of the fungal crude extracts was assessed based on the 2,2'-azino-bis(3-ethyl-benzthiazolin-6-sulfonicacid) (ABTS) method. Total phenolics were determ...

BACKGROUND Dietary antioxidant intake has been suggested to protect against oxidative damage and related clinical complications. The aim of the present study was to assess the potential relationships between the dietary total antioxidant capacity (TAC) and obesity-related features in children and adolescents. MATERIALS AND METHODS Anthropometric variables from 369 children and adolescents wer...

The total antioxidant capacities (TAC) of feces of mammalian herbivores and carnivores were compared. TAC were estimated using three different methods: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS*) reduction, 1,1-diphenyl-2-picrylhydrazyl radical (DPPH*) reduction, and ferric reducing antioxidant power (FRAP). TAC of 18 herbivorous species were generally higher with res...

Total antioxidant capacity (TAC) of some Rosmarinus officinalis L. (rosemary) extracts was investigated by an “in batch” analytical method based on chemiluminescence (CL). This method is based on a CL reaction between luminol and hydroxyl radicals generated by the hydrogen peroxide in the presence of Co(II) ions complexed with ethylene diamine tetraacetic acid (EDTA) disodium salt, according to...

Purpose: Our aim was to investigate the serum cross-linked N-telopeptides of type I collagen levels and total antioxidant capacity in patients with type 2 diabetes mellitus. Methods: 46 patients with type 2 diabetes mellitus (24M, 22F) aged 41 to 68 years (54.36 ± 7.92) and 34 healthy controls (17M, 17F) aged 40 to 69 years (52.91 ± 8.04) were enrolled in the study. Serum cross-linked N-telopep...
