Salinity stress is one of the limiting factor determining plant growth and development through negative effects on plant physiological processes. Interaction of salinity and certain plant growth regulators such as gibberellin affected physiological and biochemical responses in plants. In present research, the effects of different concentrations of sodium chloride (0, 30, 60, 90 and 120 mM NaCl)...
Introduction: One of the main mechanisms by which diabetic complications occur is an alteration of the structure and function of proteins due to hyperglycemia. Aspirin (ASA) affects cellular pathways through different mechanisms, including glycation inhibition and antioxidant activity. The aim of the present study, as a follow up to our previous one, is to investigate the effect of long-term, h...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
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...
potato tuberworm, phthorimaea operculella zeller (lepidoptera; gelechiidae) is a worldwide pest of solanaceous crops. larvae feed inside galleries in foliage, stems and tubers making chemical control unsuccessful, so other control methods should be applied. in recent years many plants have received genes that encode toxic proteins as a strategy to resist insect pests. in this study, optimal ph ...
World industrialization and population growth are the main reasons for the increase in environmental contamination with aromatic hydrocarbons. The presence of these compounds in the environment leads to a variety of stresses in plants and finally reduces their growth. Pyrene is one of the major toxic contaminants belonging to polycyclic aromatic hydrocarbons. Hence, in this research, the effect...
The effect of stocking density and dietary aflatoxin B1 along with including rosemary and thyme powders on digestive enzymes activity of rainbow trout was evaluated. 600 fish with an average weight of 90±3 were randomly allotted into six experimental groups consisted of (1) stocking at 15 kg.m-3- feeding diet devoid of aflatoxin, (2) stocking at 45 kg.m-3-feeding diet devoid of aflatoxin, (3) s...
