The main goal is to rise clients' information about their skin disease, skin cell therapy and to provide Rooyan’s Center informations, specialists list, addresses, presentations, clips and relevant photos of the disease. Methods: To identify the information, a researc...
Background: Chlamydia trachomatis(CT) is an obligate intracellular bacteria, requires living cells to replicate itself. CT infection can remain up to 4 years in the couple and affect their fertility. The relationship between CT and infertility is very important because most patients are asymptomatic and untreated. After infection with CT, NK activation signals begin through interactions of its ...
Background: Epigenetic modifications are involved in different cellular processes through regulating chromatin dynamics. histone methylation is an important modification that can be dynamically regulated by histone methyltransferase and histone demethylase enzymes. JMJD1A (also known as JHDM2A and KDM3A) is a histone demethylase specific for H3K9me2/me1. JMJD1A is a key epigenetic regulator tha...
Background Assisted reproductive techniques (ART) are used with increasing frequency worldwide. The present research was conducted to determine the effects of ART on hearing defects and ear abnormalities. MaterialsAndMethods n a descriptive, cross-sectional, non-randomized study, the status of hearing and ear abnormalities was assessed in 300 newborns conceived by ART at Royan Institute, Tehran...
Background: Diminished ovarian reserve (DOR) is a heterogeneous disorder causing infertility, characterized by a decreased number of oocytes and high FSH level, the genetic cause of which is still unknown. The association between FMR1 premutations(50-200 CGG repeats) and the premature ovarian failure( POF) disease has suggested that FMR1 gene acts as a risk factor for POF and recently for DOR p...
Introduction: Type I diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. A new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. Methods: Human embryonic stem cell lines (Royan H1) were used to produce embryoid bodies. Differentiation carried out by growth factor-mediated se...
Background and purpose : Infertility with an incidence of about 15% has mainly been one of the community burdens that have even been threatening to the continuity of the family life. One of the most prevalent causes of women infertility is ovarian causes particularly PCOS. The aim of this study was to determine the outcome of IVF & ET in women with PCOS in comparison with tubal factor. Mat...
Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...
Background With aging, the ovarian reserve is decreased and that is a major contributor to poor ovarian response to exogenous gonadotropins. The aim of the present study is to evaluate the role of Dexamethasone on ovarian response in infertile patients aged over 35 years undergoing IVF/ICSI cycles. MaterialsAndMethods In this triple blind placbo-control clinical trial study, a total of 72 infer...
