Oxidative stress has been proposed to be involved in the immunologic defeat observed in effector calls of the immune system as well as in lymphocyte cell death and viral replication in human immunodeficiency virus (HIV)-infected patients. Because thiol-containing antioxidants such as N-acetyl-L-cysteine have been shown to have beneficial effects on CD4+ lymphocyte survival and to inhibit progra...

The effects of alkalization on antioxidant activity and physical properties of chocolate were studied during conching using a chocolate recipe of the Indonesian Coffee and Cocoa Research Institute. The study was designed according to Response Surface Methodology in two variables. Alkali concentration and conching temperature were plotted in the range of 1 − 15 g kg-1 and 40 – 80°C, respectively...

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 proce...

Background and aim: Extraction of natural antioxidant compounds has recently attracted the attention of researchers. Almond is one of the native products of  Iran, which annually during the process of production , large volumes of waste is achieved. The aim of this study is investigating the impact of two parameters (time and ethanol percentage) on the extraction of phenol and ...

objective: oxidative stress as a consequence of aging can induce infertility in males. in this study, we have investigated the effects of aging on sperm parameters, intra-spermatic water soluble antioxidants, reactive oxygen species (ros), and in vitro blastocyst formation. methods: we chose 5 older nmri male mice (10-12 months) and 5 younger nmri male mice (2-3 months). sperm parameters, ros, ...

objectives:crocin is one of constituents of saffron and has antioxidant property. zinc chloride is one of the common compounds of zinc with antioxidant activity. the present study was aimed to investigate separate and combined treatment effects of crocin and zinc chloride on blood levels of zinc and metabolic and oxidative parameters in diabetic rats. materials and methods:diabetes was induced ...

drought, withnegative impacts on plant growth and development, isa major abiotic stress. in order to decreasing drought stress injuries and recognizing red peppers tolerance physiology against drought stress in greenhouse conditions, an experiment with three levels of drought stress (irrigation at 100, 60 and 30% of field capacity) and four concentrations of 5-aminolevolinic acid ((ala; 0, 0.25...

background: sperm dna damage is an important factor in the etiology of male infertility. objective: the aim of the study was to evaluate the association of oxidative stress induced sperm dna damage with the pathogenesis of male infertility. materials and methods: the study comprised a total of 66 subjects, including fertile men (n=25) and infertile men (n=41) matched by age. seminal malondialde...

This study examined the effects of a 2-mo antioxidant vitamin treatment on acute hematological and hemorheological alterations induced by exhausting exercise; both sedentary and trained individuals were employed. Eighteen young male, human subjects (9 sedentary, 9 trained by regular exercise) participated in the study and performed an initial maximal aerobic cycle ergometer exercise with freque...

introduction oxidative stress is metabolic and physiologic status caused by imbalance between free radical production and antioxidant defense of body. in some physiological status such as rapid growth, parturition, disease and high production rate that imbalance would occur. high producing dairy animals are suspected to oxidative stress and require to antioxidant supplementation. negative energ...
