Background & Objective: The purpose of study, was to investigate the effect of 8weeks incremental aerobic training with zinc supplementation on muscular enzymatic activity of superoxide dismutase and serum leptine in wistar rats. Materials & Methods: 32 Wistar rats, randomly divided into 4groups (control, training, training +zinc and zinc). The training protocol consisted of running on treadmil...
Activity of the enzymes can give information on the kind and duration of the effects of pollutants on the metabolic activity of soil. Results of studies on the dehydrogenase activity in soils experimentally contaminated with diesel fuel, with and without modification used in investigation over biodegradation process (including fertilization, stirring and inoculation) were presented in paper. St...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Introduction: Tobacco smoke is involved in the pathogenesis of several diseases in different body systems. Saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. The aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...
The objective of this study was to relate earthworm assemblage structure with three different soil use intensities, and to indentify the physical, chemical, and microbiological soil variables that are associated to the observed differences. Three soil uses were evaluated: 1-Fifty year old naturalized grasslands, low use intensity; 2-Recent agricultural fields, intermediate use intensity, and 3-...
Background and Objectives: Cinnamon contains phenolic and non-phenolic bioactive compounds. The aim of this research was investigating the antimicrobial and anti-enzymatic properties of cinnamon (Cinnamomum verum) hydrosol. Materials and Methods: In this laboratory study, chemical composition of cinnamon hydrosol was analyzed by Gas chromatography–mass spectrometry method. Antibacterial effec...
Phenolic compounds are intermediary transformation products of many naturally occurring substances and synthetic chemicals, including crop residues, organic wastes, pesticides and industrial products. They are suitable substrates for the phenolases and peroxidases produced by the soil microflora. Although measurement of the enzymatic oxidation of phenolic compounds is an important measure of th...
Silicon (Si) can protect some plants from biotic and abiotic stresses. In this research, effects of three exogenous Si levels (0, 0.85 and 1.7 mM) on growth, lipid peroxidation, lipoxygenase activity, proline content, H2O2 accumulation, and activity of non-enzymatic and enzymatic antioxidants (catalase and ascorbate peroxidase) under powdery mildew disease stress by Sphaerotheca fuliginea on pu...
