The combined effects of using cinnamaldehyde with catechin, quercetin or eugenol against wood decay fungi were examined by comparing their isoeffective concentrations to that of individual compound. Among all combinations, cinnamaldehyde with eugenol revealed the strongest synergy against Laetiporus sulphureus. The synergism was due to the interference of fungal cell wall synthesis and cell wal...

The methanolic extract of Clerodendrum viscosum Vent. (Verbenaceae) was evaluated for in vitro antioxidant activity by determination of total antioxidant capacity, assay of nitric oxide scavenging activity and reducing power test and in vivo antinociceptive effect in acetic acid induced writhing model in swiss albino mice. The results revealed the presence of pronounced antioxidant property as ...

background: the aim of this study was to analyze the effects of thoron and thermal treatment for aging-related diseases in humans. materials and methods: all subjects inhaled thoron with a high concentration (about 4900 bq/m3) for 2 weeks. blood pressures were measured and blood samples were collected after each treatment 1, 2 and 3 weeks after the first treatment. results: the α-atrial natriur...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

BACKGROUND Rhododendron anthopogonoides Maxim, a kind of traditional Tibetan medicine, has been used to remove body heat, body detoxification, cough, asthma, stomachic and swelling, eliminate abundant phlegm and inflammatory for a long time. In the present study, the total phenols and total flavonoid contents as well as antioxidative properties of the crude extract and solvent fractions of R. a...

OBJECTIVE To investigate the antihyperlipidemic, antioxidant, and cytotoxic effect of aqueous and methanol extract of leaves of Polygonum minus. MATERIALS AND METHODS Acute antihyperlipidemic effect was studied on chemically induced hyperlipidemic rat model. Treated groups received aqueous and methanol extract of leaves of P. minus respectively (1000 mg/kg; oral) whereas standard treated grou...

The avian egg is an excellent source of nutrients consisting of components with beneficial properties but there is limited knowledge on the effect of cooking methods and gastrointestinal digestion on the antioxidant activity of eggs. The present study was focused on the effect of cooking and simulated gastrointestinal digestion on antioxidant activity of eggs using ORAC, ABTS and DPPH assays. T...

BACKGROUND The xanthine structure has proved to be an important scaffold in the process of developing a wide variety of biologically active molecules such as bronchodilator, hypoglycemiant, anticancer and anti-inflammatory agents. It is known that hyperglycemia generates reactive oxygen species which are involved in the progression of diabetes mellitus and its complications. Therefore, the deve...

Placenta, as a reservoir of nutrients, has been widely used in medical and cosmetic materials. Here, we focused on the antioxidant properties of placental extract and attempted to isolate and identify the main antioxidant factors. Porcine placental extracts were prepared through homogenization or acid hydrolysis, and their antioxidant activity was investigated in the human keratinocyte HaCaT ce...

neurotoxicity following cerebral ischemia-reperfusion. Accumulation of ROS, particularly superoxide anion (O ) and hydrogen peroxide (H2O2) causes damage to membrane phospholipids, proteins and DNA. Under normal circumstances, these oxidant species can be effectively scavenged by antioxidant enzymes, namely superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPX). In mammalian SOD...
