introduction: mesenchymal stem cells can be isolated from adult tissues, such as the adipose tissue, or other sources. among all these sources, adipose tissue because of easy access, and placenta due to its immunomodulatory properties, in addition to another useful properties, were attracted more attention to themselves. isolation and comparing these two different sources can help us for access...

introduction  insulin-like growth factor i (igf-i) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. igf-i plays the roles via the receptor (igf-ir) signaling pathway. igf-ir unlike igf-i is expressed strongly in the developing liver, but much more weakly in adults. objective:  we hypothesiz...

background  the mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. this source of stem cells avoids invasive procedures and the ethical controversy of embr...

background  multiple procedures (lumbar puncture and bone marrow aspiration /biopsy) cause pain, stress, depression and etc for the patients and their families. various methods have been recommended for pain reduction during invasive procedures. the aim of this study is to report the complications following general anesthesia. methods in this prospective observational study, two hundred and two...

background sall gene family represent a group of evolutionary conserved zinc finger transcription factors which are involved in normal development. it includes four members (sall1 to sall4). sall4 has significant roles in the maintenance of pluripotency and self-renewal, efficient proliferation /stabilization and cell fate decision of embryonic stem cells (escs). our aim in this study was to an...

stem cell-based therapy has great potential in treating health conditions including cardiovascular, autoimmune, type i diabetes, neurodegenerative and bone and cartilage diseases also in spinal cord injuries, malformations and cancer. in addition to their potential use to treat systemic diseases, stem cell-based therapy also provides a powerful tool to treat oral and dental diseases such as cra...

introduction: chemokine receptors are found on the surface of stem cells. there have been 19 distinct chemokine receptors described in mammals. chemokines are major players in migration and homing. therefore, changes in their levels or function can help us to increase the migratory potential of these cells. valproic acid differs in structure from other drugs in common use. the way in which valp...

refractory celiac disease (rcd) is when malabsorption symptoms and villous atrophy persist despite strict adherence to a gluten free diet (gfd) for more than 12 months and other causes of villous atrophy have been ruled out.  rcd is considered a rare disease and almost exclusively occurs in adults. persistent diarrhea, abdominal pain, weight loss are the most common symptoms in rcd. also, anemi...

the diagnosis of functional constipation (fc) is usually straightforward. almost 95% of childhood constipation is functional in nature. the remaining 5% can be attributed to wide variety of conditions. many of these etiologies are obvious by history and examination and many have other specific symptoms besides constipation. it is especially important to look for presence of any symptoms or sign...
