Background Obesity is characterized by a deposition of abnormal or excessive fat in adipose tissue, and is linked with a risk of damage to several metabolic and pathological processes associated with oxidative stress. To date, salivary oxidative biomarkers have been minimally explored in obese individuals. Thus, the aim of this study was to assess the concentrations of salivary oxidative biomar...

Background & Aims: Date palm fruit is one of the highly consumed foods with antioxidant compounds and high nutritive value in Iran. In this study, total phenolic compounds and antioxidant capacity of three varieties of date palm (Hajmohamadi, Kabkab, and Khasi) in three stages of ripening were investigated. Methods: This was a laboratory study. Palm fruits of Hajmohamadi, Kabkab, and Khasi vari...

a number of 6-hydroxy-2-benzylidene-3-coumaranones were synthesized from condensation of 6-hydroxy-3-coumaranone with appropriate aldehydes and were evaluated for their antioxidant activities. the antioxidant activity was assessed using two methods, including, 1,1-biphenyl-2-picrylhydrazyl (dpph) radical scavenging, and reducing power assays. some of the benzylidene coumaranones showed antioxid...

Three amidines, N, N’-Diphénylbenzamidine (1), N-Cyclohexyl-N’-phényl-octamidine (2), N, N’diphényldodécamidine (3), were synthesized and investigated for their antioxidant activity using 2, 2-diphenyl-1picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP) and β-carotene/linoleic acid assays. The results indicated that amidines tested possess good antioxidant activi...

In the present study, methanol and aqueous extracts of Parkinsonia aculeata L. leaves were prepared and analyzed for phytochemical analysis and antioxidant potential in different in vitro assays. Antioxidant activity was studied using DPPH, CUPRAC, reducing power assay, deoxyribose degradation (site and nonsite specific), ferric reducing antioxidant potential (FRAP), ferric thiocyanate (FTC), t...

Poverty, drug resistance and other factors including increasing difficulty in the control of mosquitoes (the vector of the causative organism of malaria), have led to a growing interest in phytochemical research. The antioxidant activity of Newbouldia laevis stem bark was investigated. Air dried stem bark of N. laevis was powdered and extracted with 95 % v/v methanol by maceration, and the extr...

The various risk factors for peripheral arterial disease (PAD) are almost identical to those for atherosclerosis and include abnormal levels of lipids or lipoproteins. Lipid peroxidation parameters and total antioxidant capacity in the serum of male patients with PAD before surgery as well as 3-5 days and 7-10 days after surgery were measured. We also compared these parameters with those in a g...
