Background: The present study examined the possible role of endogenous opioidergic system in effect of food deprivation on formalin-induced nociceptive behaviors in male and female rats. Also, we investigated the effect of food deprivation on the plasma level of beta-endorphin and sex hormones. Methods: Food was withdrawn 48 h prior to performing the formalin test, but water continued to be ava...

introduction: the concentration of noradrenalin and corticosterone as the two nociception modulators change after fasting or stress situation. the aim of present study was to investigate the effect of food deprivation on formalin-induced nociceptive behaviours and plasma levels of noradrenalin and corticosterone in rats. methods: food was withdrawn 12, 24 and 48 h prior to performing the formal...

Background and Aims: It is well-recognized that endogenous opioidergic system plays an important role in pain sensitivity, pain perception, and response to some stressing situations. The present study examined the probable role of endogenous opioidergic system in effects of food deprivation on formalin-induced nociceptive behaviors in male and female rats. Methods: To make short-term food d...

objective: the goals of the study are evaluation the effect(s) of food deprivation as a social stress on testis structure. we also investigated the effects of melatonin treatment as an antioxidant component and inequality on the effect(s) of food deprivation. methods: we investigated the improving effects of melatonin and social stress (food deprivation) on 42 male rats in 7 groups including co...

OBJECTIVE Although the sociodemographic characteristics of food-insecure households have been well documented, there has been little examination of neighbourhood characteristics in relation to this problem. In the present study we examined the association between household food security and neighbourhood features including geographic food access and perceived neighbourhood social capital. DES...
