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...

introduction: colonoscopy is an invasive method that is painful for patient especially for children. the objective of this research was investigation into the effect of supermint oral drop (peppermint essence) on the patient and colonoscopist group satisfaction during colonoscopy.   material and methods: in this clinical trial study, 101 children candidate colonoscopy (7-14 years old) in childr...

introduction:  the aim of the present study was to investigate the presence and the frequency of eaec as etiologic agent of diarrhea in shiraz. enteroaggregative e. coli (eaec) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide.   materials and...

introduction: endoscopy is an invasive and painful procedure in children. since children can not tolerate pain and stress, sedation is necessary in pediatric endoscopy. the aim of this study was comparison of propofol versus intravenous midazolam for reducing anxiety in children.   materials and methods: in this study, 103 patients (2-14 years old) in whom endoscopy was indicated were divided i...

congenital hepatic fibrosis (chf) is a rare disease that affects both the liver and kidneys.  congenital hepatic fibrosis (chf) is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. affected individuals also have impaired renal function, usually caused, in children and teenagers, by an...
