BACKGROUND/AIMS Several lines of evidence point to the role of neurobiological mechanisms and genetic background in bipolar disorder (BD). The interleukin-1 receptor antagonist (IL-1Ra) is the principal regulator of IL-1α and IL-1β bioactivities. This study aimed to investigate the potential role of the variable number of tandem repeats (VNTR) polymorphisms(More)
Research about potential use of stem cells for the development of germ line cells in vitro had been challenged. In the present study, we reported a novel protocol consisting of cocktail growth factor addition for germ cell differentiation followed by transfection. The cells were purificated based on the expression on the cell surface of a protein. This(More)
BACKGROUND Mesenchymal Stem Cells (MSCs) are multipotent cells that can be collected from different sources. Under specific conditions, MSCs can be differentiated to tissue specific cells in vitro. Human Umbilical Cord mesenchymal Stem Cells (hUCMSCs) can easily be harvested and cultured in in vitro conditions. Production of germ cells from mesenchymal stem(More)
BACKGROUND Catsper proteins are responsible for entering Ca(2+) to the cell and play an important role in sperm motility and male fertility. Antioxidants are vital for sperm motility too. Escanbil (Calligonum) extract possess some of the important antioxidant like Catechin and Quercetin. OBJECTIVE Here we investigated the effects of Escanbil (Calligonum)(More)
OBJECTIVES Mesenchymal stem cells (MSCs) derived from Wharton's jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. MATERIALS AND METHODS MSCs were isolated from human Wharton's jelly and treated with BMP4,(More)
Human umbilical Wharton’s jelly-derived mesenchymal stem cells (HWJMSCs) are the best candidate to get plentiful stem cells and differentiate them to germ cells under appropriate conditions to treat infertility. We sought to determine under which conditions HWJMSCs could form male germ cells in vitro. So, HWJMSCs were differentiated to male germ cells under(More)
BACKGROUND Endometrial integrin expression changes might be a reason for implantation failure in polycystic ovarian syndromes (PCOS). Objective : Assessment of integrin genes and proteins expression upon endometrium in the PCOS experimental mouse model was the main goal of this study. MATERIALS AND METHODS 30 NMRI female mice were equally divided into(More)
OBJECTIVES Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial(More)
Background: Some evidences showed that the secretion of uterine tube, vagina and follicular fluid (FF) affects X and Y-chromosome populations. Sperm selection with X or Y chromosome can added to oocyte for gender desired. The isolation of X, Y sperm have done and all efforts in this field are done to make culture media similar to in vivo condition. The(More)
OBJECTIVES P In vitro chemosensitivity and resistance assays (CSRAs) are a promising tool for personalized treatment of glioblastoma multiform (GBM). These assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. We aimed to assess the feasibility and validity of utilizing stereotactic biopsies of GBM in(More)
