Administration of nicotine leads to incentive and behavioral tolerance in human and animals. Ascorbic acid administration inhibits some effects of nicotine. In the present study, the effects of ascorbic acid administration on the expression and development of nicotine-induced behavioral tolerance in female Swiss-Webster mice (20-25 g) was investigated. Animals were injected with nicotine (0.5 m...

the subject of transplant immunosuppression has generated significant interest in recent years. excellent immunosuppression, advances in surgical technique, post-transplantation care, and infection control have resulted in excellent outcomes. there is widespread support for the notion that the fundamental objective in transplant immunology should be the achievement of specific graft tolerance. ...

hyperglycemia and gestational diabetes mellitus are complications of pregnancy. both mothers and newborns are typically at increased risk for complications. this study sought to determine effect of zinc supplementation on serum glucose levels, insulin resistance, energy and macronutrients intakes in pregnant women with impaired glucose tolerance.in this clinical trial 44 pregnant women with imp...

introduction: the need to have a safe relationship with other people is something substantial. on the basis of the fact that human beings have various lingual, ethnical, cultural, social as well as economical differences, social leniency is supposed to be the only way to provide a sound relationship without existence of any type of quarrel among people. the significance of attention to such a c...

salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...

in several parts of the world, important yield losses are caused to faba bean due to attack by the black bean aphid aphis fabae scopoli. although resistance could be a good alternative to chemical control, its genetic basis is still largely unknown; and its phenotypic expression is still poorly described, making crucial the permanent evaluation of genetic resources available in different countr...

a solution culture experiment was conducted to evaluate the salinity tolerance of 15 tomato genotypes in hoagland’s nutrient solution with three levels of nacl (0, 75, and 150 mm). the experiment was conducted in completely randomized design with three replicates. after 30 days of imposition of salt stress, gas exchange parameters including transpiration rate, stomatal conductance, co2 assimila...
