Response of Antioxidant Enzymes in Pyrchantha Coccnia as Biomarkers for the Detection of Pb in Urban Atmosphere
The utility of antioxidant enzymes, via superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione peroxidase (GPX), as biomarkers of lead pollution in urban atmosphere of Baku was investigated by using the Pyrchantha coccnia. At higher lead concentrations (105.74 ppm), CAT, SOD, APX and GPX exhibited remarkable induction (22.9968, 3.3664, 3.324 and 81.318 unit g-1 FW, respectively) with increasing ... إقراء المزيد

Detection and partial characterization of a putative closterovirus affecting Ficus carica: molecular, ultrastructural and physiological aspects of infected leaves
_Fig mosaic disease_ (FMD) was systemically transmitted to susceptible fig plants by grafting and led to development of symptoms including a wide array of discoloration, green blisters, mottling, crinkling and deformation of leaves and fruits. A sensitive assay for the detection of FMV using specific enzyme-linked immune sorbent assay and reverse transcription-polymerase chain reaction was developed. A double-stranded RNA ca. ... إقراء المزيد

Contamination of environment by radionuclides in territories under urboecosystem conditions is an actual problem. The search for new express methods for radioactivity determination of environment is an important task of research. The present work evaluated the ability to use _Eucalyptus globulus_ leaves to act as bio-monitor for environmental radionuclides air pollution. The accumulation features of radionuclides (226Ra, 232Th, 40K) in ... إقراء المزيد

Behavioral, hepato-morphological, and biochemical studies on the possible protective effect of black seed and water bath against change-mediated heat stress on pigeon
Background: Heat stress condition (34 °C, Egyptian summer season) in pigeon leads to a lot of negative impacts on behavior, physiology, hepatic architecture, and biochemical parameter changes. The aim of this study was to evaluate the effect of water bath as a managerial and low-quality diet (wheat) as well as some feed additives (propolis or black seed) as nutritional factors ... إقراء المزيد

Protective Effect of Lycium Barbarum Extract as Antioxidant Agent on Roridin A: Induced Hepatotoxicity in Male Rat
Abstract The fruit goji berry of Lyciumbarbarym, a traditional Chinese herbal medicine, has been widely used in healthy diets due to its potential role in the prevention of chronic diseases. We studied the effects ofroridin A toxin in male rat liver and their amelioration by goji extract. Thirtymale adult albino rats were divided into three groups (10 rats each). Group ... إقراء المزيد
