introduction: according to previous studies, colchicine causes neuronal destruction and learning depression. in this project, effects of colchicine injection into the ca1 and interaction between colchicine and nitric oxide (no) in this area on the expression of drug-seeking behavior were investigated. methods: wistar rats (250-300 g) were bilaterally cannulated at the ca1 area. colchicine (2-8 ...
Background: Various investigations have established that carbon tetrachloride (CCl4), a clear, colourless, volatile, heavy and nonflammable liquid, causes generation of free radicals in many tissues such as testis. a wide range of side effects such as reproductive toxicity has been observed following the administration of this liquid in experimental animals. Numerous studies have shown that amo...
the choice of an efficient breeding procedure depends to a large extent on knowledge of the genetic system controlling the character to be selected. the objective of this study was to determine genetic parameters for yield and other traits including some of the yield components under three planting densities, using analysis of generation means (p1, p2, f1, f2, bc1 and bc2) derived from crosses ...
Accelerated aging test to estimate the percentage of emergence are designed to lay the seeds for life, as well as an indicator to determine the power of the seed used. In this study, the effects of aging zero (control), 2, 4 and 6 days on germination index of rapeseed genotypes including Okapi, R15, BAL11, L109, BAL2 Were detected in a factorial experiment based on completely randomized design ...
objective : in this study, the effects of estradiol valerate and raloxifenea selective estrogen receptor modulator; (serm) on morphine induced sensitization were examined in mice memory, according to the step-down passive avoidance task. method: the mice received morphine or estradiol and raloxifene for three days alone or in combination with morphine. after a drug free period of 5 days, the su...
This study assessed how parents who placed their children in a model infant and toddler center were, over time, influenced by three salient features of the center: its child-centered focus, its social orientation, and its support for men in nurturing roles.
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
One of the major field constraints to seed production in safflower has proven tobe soil born pathogens, Phytophthora drechsleri and Pythium ultimum. In order toevaluate the efficiency of a field-laboratory selection method to improve resistanceof safflower against soil born pathogens, Ph. drechsleri and P. ultimum, a two-yearinvestigation was conducted. The results showed that selection is an e...
