stress refers to the degree of force used in producing a syllable. all of the words in lexicon regardless of the apparent structure and the number of their syllables have their own stress. given that the regularities governing stress assignment in persian depend on the type of lexical category and that persian speakers have a tendency to assign stress at the end of words, the goal of the presen...

to evaluate the effect of different levels of drought stress on some physiological parameters in strawberry, potted experiment involing strawberry cultivars  ‘marak٫ , ‘camarosa٫ and ‘gaviota٫ was conducted during summer 2009. the experiment consisted of three drought stress levels in three replications. the experimental arrangement was a factorial one, based upon a randomized complete block de...

objective: lc/na system is activator of hypothalamic–pituitar–adrenal (hpa) axis and cold stress triggers an equally robust increase in plasma na. increased lhrh content probably due to absence or decrease of ne release from the lc and positive feedback action of e2 on lh secretion show that in late proestrous phase na, lh and e2 have a strong link. this study was conducted to evaluate the effe...

Introduction: The role of different parts of the extended amygdala in metabolic signs of stress is not well understood. In the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (NAc) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat.  Methods: Male Wistar rats (W: 230-250 g) were canuulated un...

experimental study of the cyclic behavior of unsaturated materials is more complex than that of the saturated materials due to the required equipment, experience and time. furthering investigations in the field of unsaturated materials is necessary to better understand its complexity and sensitivity of unsaturated cyclic parameters to different determinants such as suction path, stress path, lo...

Stress and chronic pain have been shown to prevent the development of tolerance to morphine analgesia, which appears to be related to neuroendocrine activity and alternation in neurochemicals. Also the involvement of nitric oxide (NO) has been implicated in tolerance to morphine analgesia. In our pervious study, we showed that co-administration of swim stress (ss) with chronic morphine, prevent...
