conclusions traumatic abdominal wall hernia tawh, although uncommon, is associated with significant rate of morbidity and mortality in cases of delayed diagnosis and intervention. early intervention leads to a significantly better outcome. introduction acute abdominal wall rupture with visceral herniation due to blunt traumas and bowel incarceration or perforation are generally rare phenomena. ...

background: nicotine can activate dopaminergic neurons within the ventral tegmental area (vta). however, there is no evidence about complete inhibition of vta on nicotine reinforcement. methods: in the present study, we used conditioned-place preference (cpp) method to study the effect of transient inhibition of left and/or right side of the vta by lidocaine on nicotine reward properties. male ...

background and objectives: studies have documented the morhplogical, neurochemical and functional difference between the dorsal and ventral zones of hippocampus. the aim of this study was to assess the effects of chronic diabetes mellitus type1 on ventral and dorsal zones of hippocampus. methods: experimental diabetes was induced by stereptozotocin at a dose of 60 mg/kg. at the end of 8 weeks ...

background trocar site, incisional hernia is one of the serious complications of laparoscopic surgery. as a result, many surgeons prefer to close the fascia, especially in those sites where a trocar of 10 mm in size or larger has been inserted. on the other hand, suturing the fascia may lead to damage of other tissues, such as the intestines; hence, some surgeons prefer not to close the fascia....

the catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. studies reported that mor...

introduction: the most common interpretation for the mechanisms of antidepression is the increase of the brain monoamine levels such as dopamine (da). the increase of da can reduce depression but it can also decrease the monoamine release because of autoreceptor inhibition. although bupropion can decrease the dopamine release, there is evidence about stimulatory effects of chronic application o...

absracta rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. the superior root of the ansa cervicalis was formed by the c1 ventralramus. it accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. moreover the c1 ventral ramus formed fromthe sheath and joined the inferior root from c2 and c3 ventr...
