introduction: it has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. this phenomenon is named remote preconditioning of trauma. since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-rep...

Introduction: Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-2 (Nox2) is one of the predominant sources of ROS production during myocardial ischemia-reperfusion and can be induced by angiotensin II. The evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. The mechanism...

The incidence and severity of primary cardiac events are inversely related to the plasma concentration of high-density lipoproteins (HDLs). We investigated whether HDLs may exert a direct cardioprotection in buffer-perfused isolated rat hearts, which underwent a 20-minute low-flow ischemia followed by a 30-minute reperfusion. The administration of HDLs at physiological concentrations (0.5 and 1...

introduction: extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. cerebral venous sinus thrombosis (cvst) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. case presentation: a case of cvst masqueraded as high altitude cerebral edema (hace) at 6700 m/22000 ft in karakoram himalayas. atypical ol...

objective: the morphology of anterior cerebral artery (aca) in patients with hydrocephalus was analyzed (hcp), and its importance was discussed in maintaining cerebral perfusion. materials & methods: two groups were created for the study. group 1; patients with hydrocephalus and group 2; as control group without hcp. in both groups, the length of the a2 segment of aca was measured from its orig...

objectives: the high number of cerebral palsy, the severe disability of this disorder, depression in disabilities, and long lasting effects of the child`s disability on the family especially mothers are the common issues. the purpose of this study was investigating the level of depression in mothers with cerebral palsy children and its related factors. methods: this caused comparative study was...

Nanobiotechnology is the assembling of biological molecules into nanodimension complexes. This has been used for the preparation of polyhemoglobin formed by the assembling of hemoglobin molecules into a soluble nanodimension complex. New generations of this approach include the nanobiotechnological assembly of hemoglobin, catalase, and superoxide dismutase into a soluble nanodimension complex. ...
