introduction there are one million deaths from asphyxia in newborn annually. management of this newborn is only supportive. autologuse stem cell therapy may reduce mortality and long term morbidity. outcome of asphyxiated newborn is related to damage cns cells. stem cells prevent apoptosis and induce repairmen of injured neurons. methods in a review study all article related to three keywords o...

dental pulp stem cells (dpscs) can be found within the cell rich zone of dental pulp. these stem cells, under specific stimuli, differentiate into many cell types which have wide therapeutic applications.   the dental stem cells are derived from both deciduous and permanent teeth. the viable dental stem cells are very simple to collect, without any mortality and morbidity. dental pulp stem cell...

background: to date, several imaging techniques to track stem cells are used such as positron emission tomography (pet), single photon emission computed tomography (spect), bioluminescence imaging (bli), fluorescence imaging, ct scan and magnetic resonance imaging (mri). although, overall sensitivity of mri compared to spect and bioluminescence techniques are lower, but due to high spatial reso...

considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. in enzymatic digestion method extracted teeth as denta...

background  buccal fat pad is known as anatomic structure in between the masticatory muscles that separate these muscles from each other and surrounding bone. ease of access, through the intraoral route makes it suitable choice for obtaining adipose derived stem cells. methods  intraoral incisions for getting access to the buccal fat of pad are; retromolar incision, incision in medial of pteryg...

introduction nowadays, due to drug abuse the world community has suffered  considerable  losses,  resulting  from productivity loss;  transmission  of  infectious  diseases; physical,  mental,  social  and  family  problems  and disabilities; increased crime rates; the need for providing health care  practices;  threatened  personal  safety;  and decreased life quality.   crack, a cheap, highly...

the use of animal models in modeling of human genetic disease has many advantages. in some cases, however, this method may not be applicable due to some limitations, such as differences in tissue composition, anatomy and physiology of humans and animals. isogenic human disease models are a population of cells that are selected or engineered to model a specific genetic disease, in vitro. they ar...

autoimmune hepatitis is a chronic hepatitis that occurs in children and adults of all ages. diagnosis is based upon characteristic serologic and histologic findings and the exclusion of other forms of chronic liver disease. guidelines issued by the aasld suggest the following diagnostic considerations: the diagnosis should be made in patients with compatible clinical signs, symptoms, and labora...

prebiotic: a nondigestible food ingredient that benefits the host by selectively stimulating the favorable growth and/ or activity of 1 or more indigenous prebiotic bacteria. prebiotics can modify the intestinal flora and interact with the immune system of the host against specific pathogens. however clinical trials are currently limited and a beneficial effect of prebiotic in treatment acute d...

introduction: diarrheal diseases are a serious health problem and important causes of growth retardation and death in the developing world, especially those of prolonged duration. since diarrhea is constantly found in children with zinc deficiency, very studies supported zinc supplements beneficial on the duration and severity of diarrhea among children. we review the impact of zinc effects on ...
