Objective: Considering that cannabinoids protect neurons against neurodegeneration, in this study, the neuroprotective effect of WIN55,212-2 in paraoxon induced neurotoxicity in PC12 cells and the role of the N-methyl-D-aspartate (NMDA) receptor were evaluated. Materials and Methods: In this study PC12 cells were maintained in Dulbecco's modified eagle’s medium (DMEM+F12) culture medium supplem...

Production and activity of interleukin (IL)-1β are kept under strict control in our body, because of its powerful inflammation-promoting capacity. Control of IL-1β production and activity allows IL-1 to exert its defensive activities without causing extensive tissue damage. Monocytes are the major producers of IL-1β during inflammation, but they are also able to produce significant amounts of I...

Evidence suggests that individuals who are more obese may be more responsive to stress. Stress activates the sympathetic nervous system (SNS) and the adipose-tissue cytokine leptin stimulates SNS activity in animals. We examined the relationship between adiposity, leptin and physiological responses to acute laboratory stress in 67 women. We predicted that individuals with greater adiposity and/...

(1) Background: Preoptic region of hypothalamus is responsible to control maternal behavior, which was hypothesized be associated with gene expressional changes. (2) Methods: Transcriptome sequencing first applied in the preoptic rat dams comparison a group mothers whose pups were taken away immediately after parturition and did not exhibit caring behavior 10 days later. (3) Results: Differenti...

Aldosterone is traditionally viewed as a hormone regulating electrolyte and blood pressure homeostasis. Recent studies suggest that Aldo can cause microvascular damage, oxidative stress and endothelial dysfunction. However, its exact cellular mechanisms remain obscure. This study was undertaken to examine the effect of Aldo on superoxide production in human umbilical artery endothelial cel...

Although the epileptogenic properties of estrogens have been widely demonstrated in several models and species, the mechanism(s) by which estrogens can acutely change seizure parameters including after discharge and seizure duration remain remains to be determined. In the present study, we examined the role of NMDA (N-methyl-D-aspartate), non-NMDA and estrogenic receptors in estradiol benzoate ...

We tested the hypothesis that combined administration of IL-1 and TNF antagonists would protect fracture healing from inhibition by chronic ethanol exposure. Adult male rats were fed a liquid diet +/- ethanol (CON and ETOH) by intragastric infusion for three weeks prior to and three weeks after creation of an externally fixated tibial fracture. Beginning the day of fracture, one-half of each di...

To investigate the role of the pro-inflammatory cytokine interleukin-1β (IL-1β) in postoperative cognitive dysfunction (POCD) in aged rats, we used laparotomy to mimic human abdominal surgery in adult (3 months) and aged (24 months) F344/BN rats. We demonstrated that memory consolidation of the hippocampal-dependent contextual fear-conditioning task is significantly impaired in aged but not you...
