Objective(s):Dependence and tolerance to opioid analgesics are major problems limiting their clinical application. a-Terpineol is a monoterpenoid alcohol with neuroprotective effects which is found in several medicinal plants such as Myrtus communis, Laurus nobilis, and Stachys byzantina. It has been shown that some of these medicinal plants such as S. byzantina attenuate dependence and toleran...
Introduction: Stress inhibits the development of tolerance to morphine analgesia via activating Hypothalamic- Pituitary-Adrenal (HPA) axis. Modified catecholamine systems have been reported following morphine tolerance development. In the current study we tried to evaluate changes in the gene expression levels for MAO-A, MAO-B, COMT and thyrosine hydroxylase (TyH) enzymes following chronic p...
Intorduction: Today, social tolerance is a necessary precondition for living in higher population densities and types of cultural behavior. The purpose of this study was to measure social tolerance and its social related factors in Bandar Abbas. Method: The strategy of this research is comparative and the survey technique and questionnaire tools have been used to collect data. The statistical...
Chlorine and sulfate toxicity in water and soils are the main factors limiting growth and yield of most plants. Tolerance and sensitive indexes related to Cl and SO4 in irrigation water and effect of nitrogen fertilizer on barley were evaluated in a completely randomized design with three replications, under greenhouse conditions. Quantity salinity tolerance and susceptibility indices such as M...
Introduction: Sex differences are observed in the development of tolerance to antinociceptive effect of opioid drugs such as morphine, but the underlying mechanisms remain unclear. Critical role of glutamate in the development and maintenance of opioid tolerance has been reported by many investigators. There are also evidences about interaction between gonadal hormones and neuromodulatory sy...
Abstract The researchers have been interested to explore the impact of personality traits on second or foreign language learning. The current study is an attempt to investigate whether there exists a statistically significant relationship between introvert and extrovert EFL learners’ willingness to communicate and ambiguity tolerance. To this end, a total of 150 EFL learners completed the Intro...
This study was conducted at the Research Farm of Isfahan University of Technology in 2003 to evaluate drought tolerance potential of 20 oat (Avena sativa L.) genotypes including 14 cultivars released in Canada, two cultivars released in the United States of America and Switzerland and four Turkish breeding lines. A randomized complete block design with three replications was used in each irriga...
Background and Aims: The opioid system plays a key role in opioid tolerance and dependence. On the other hand, they have shown that the opioid system plays a role in the analgesic effects of Ferula gummosa extract. Therefore, the aim of the present study is to investigate the effect of Ferula gummosa essential oil (FGEO) on morphine tolerance and dependence in mice. Materials and Methods: In t...
environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...
Drought stress is one of the most important abiotic factors which adversely affects growth, metabolism and yield of crops worldwide. The goal of the research was identify drought tolerate canola genotypes using the different drought tolerance indices. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricult...
