oxidation of low density lipoprotein (ldl) particles plays a key role in the etiology of atherosclerosis and coronary artery disease (cad). oxidative stress enhances the likelihood of ldl oxidation and atherosclerotic plaque development. paraoxonase (poni) is an enzyme associated with hdl that metabolizes organophosphates and has antioxidant activity. in order to investigate the relationship be...

Abstract Objective Amaranths leaves are rich in ascorbic acid and polyphenol compounds which have antioxidant activity. The aim of this study was to evaluate their vivo effect consumption Amaranth leaf extract on activity, catalase enzyme activity H 2 O induced oxidative stress Drosophila melanogaster flies assessed. Results Consumption associated with increased survival exposure o a dose depen...

Berries have shown several cardiovascular health benefits and have been associated with antioxidant functions in experimental models. Clinical studies are limited. We examined the antioxidant effects of freeze-dried strawberries (FDS) in adults [n = 60; age: 49 ± 10 years; BMI: 36 ± 5 kg/m(2) (mean ± SD)] with abdominal adiposity and elevated serum lipids. Participants were randomized to one of...

background: the rosemary extract (re) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. in this study, we postulated which doses of re have a more effect on the hippocampus of middle-aged rats.   methods : in this experimental study, thirty-two middle-aged male wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of re (containing 40% carnosic ac...

Cryopreservation of seabass (Lates calcarifer) semen is an approach to increase the quantity and quality of seabass fry in aquaculture. However, cold shock can induce sperm injury leading to structural damage of the plasma membrane and loss of motility. Thus, the effect of cryopreservation on fatty acid composition and antioxidant enzyme activities of seabass sperm was determined. In cryopreser...

Rare earth element pollution (REEs) and acid rain (AR) pollution simultaneously occur in many regions, which resulted in a new environmental issue, the combined pollution of REEs and AR. The effects of the combined pollution on the antioxidant enzyme system of plant roots have not been reported. Here, the combined effects of lanthanum ion (La3+), one type of REE, and AR on the antioxidant enzym...

Oxidative stress, an important factor in modulation of glycolytic pathway and induction of stress activated genes, is further augmented due to reduced antioxidant defense system, which promotes cancer progression via inducing angiogenesis. Curcumin, a naturally occurring chemopreventive phytochemical, is reported to inhibit carcinogenesis in various experimental animal models. However, the unde...

In most southern provinces of Iran, Soil Salinity is a growing problem particularly in the irrigated agricultural areas and has been found to reduce crop yields. In order to investigate the role of pod removal in seed germination, seedling growth and antioxidant enzymes activity in annual medics (Medicago scutella L.) under salinity stress conditions, a factorial experiment was conducted at Col...

seedlings of five canola genotypes (hyola308, hyola401, hyola60, optlon50, and rgs003), were grown in hoagland nutrient solution containing s1=0, s2=100, s3=200 and s4=300 mm nacl in controlled environment. such antioxidant activities as catalase (cat), ascobrate peroxidase (apx) and guaiacol peroxidase (gpx), as well as osmolyte concentration (proline), chlorophyll fluorescence and some enzyme...

Marine actinomycetes are potential source for the discovery of novel compounds and enzymes. Though extensive research on marine actinomycetes is underway globally, the actinomycetes research from Indian marine ecosystem is unexplored and understudied. Hence, the present research is focussed on the screening of bioactive compounds from marine actinomycetes isolated from Indian coastal region. Th...
