main aim of this research was comparing mild swimming and recoveries jacuzzis recovery on blood lactic acid and blood pressure of swimmers. we used descriptive statistics (placebo, median, mean, variance, and standard deviation) for analyzing data in order to compare changes of saturated percentage of blood cell. we collected data from pools of mashhad and we used from 45 person for collecting ...

In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...

ventricular fibrillation is the cause of the most sudden deaths. the recent findings have clearly proved the correlation between the slope of restitution curve with ventricular fibrillation. cellular automata is a powerful tool for simulating complex phenomena in a simple language. in this paper, a simple model is proposed for the simulation of the property of restitution in a single cardiac ce...

Background: The hematopoietic system is sensitive to the adverse effects of ionizing radiation. Cellular therapies utilizing mesenchymal stem cells or vascular endothelial cells have been explored as potential countermeasures for radiation hematopoietic injuries. We investigated cells cultured from amnion                ...

objective: cryopreservation of immature testicular tissue should be considered as an important factor for fertility preservation in young boys with cancer. the objective of this study is to investigate whether immature testicular tissue of mice can be successfully cryopreserved using a simple vitrification procedure to maintain testicular cell viability, proliferation, and differentiation capac...

Neurogenic bladder (NGB) secondary to spinal cord injury (SCI) is accompanied with several complications such as urinary tract deterioration, urinary incontinence, and consequently lower quality of life (QoL), significant morbidities, and occasionally death. Current therapeutic methods have some side effects and there is no treatment for the upper urinary tract injuries. Stem cell therapy is a ...

spinal cord injury (sci) is a destructive condition that the cord can't send signals below the level of the injury. despite advances in the medical and surgical care of sci patients, no effective treatment exists for the neurological deficits of sci. cell therapy is a new approach for sci, and preclinical models demonstrate that cell transplantation can improve some secondary events throug...
