PURPOSE PCNL (percutaneous nephrolithotripsy) is usually performed in the prone position. The supine position has potential advantages comparing with the prone position. Our objective is comparison between the outcome of PCNL in the complete supine position and the standard prone position. MATERIAL AND METHODS A total of 80 patients who underwent PCNL(More)
BACKGROUND The failure of regeneration after spinal cord injury (SCI) has been attributed to axonal demyelination and neuronal death. Cellular replacement and white matter regeneration are both necessary for SCI repair. In this study, we evaluated the co-transplantation of olfactory ensheathing cells (OEC) and embryonic stem (ES) cell-derived motor neurons(More)
The aim of this study was to evaluate the effect of sperm DNA damage and protamine deficiency on fertilization and embryo development post-intracytoplasmic sperm injection (ICSI), and also to assess the effect of protamine deficiency on DNA damage. Semen samples were collected from 28 patients participating in the ICSI programme. Following sperm preparation(More)
To associate glucose-6-phosphate dehydrogenase (G6PDH) activity in goat oocytes with intracellular glutathione (GSH) content, meiotic competence, developmental potential, and relative abundance of Bax and Bcl-2 genes transcripts. Goat oocytes were exposed to brilliant cresyl blue (BCB) staining test and categorized into BCB+ (blue-cytoplasm), and BCB−(More)
OBJECTIVE To describe the possible effects of cryotop vitrification on maturation rate and ultrastructural morphology of human in vitro matured germinal vesicle (GV) oocytes. STUDY DESIGN A total of 301surplus immature GV oocytes obtained from infertile patients were allocated into two groups: (i) GV oocytes (n=150) matured in vitro (fIVM), and (ii) GV(More)
Friedreich ataxia (FRDA) is the most frequent progressive autosomal recessive disorder associated with unstable expansion of GAA trinucleotide repeats in the first intron of the FXN gene, which encodes for the mitochondrial frataxin protein. The number of repeats correlates with disease severity, where impaired transcription of the FXN gene results in(More)
The purpose of this study was to fabricate a conductive aligned nanofibrous substrate and evaluate its suitability and cytocompatibility with neural cells for nerve tissue engineering purposes. In order to reach these goals, we first used electrospinning to fabricate single-walled carbon-nanotube (SWCNT) incorporated poly(L-lactic acid) (PLLA) nanofibrous(More)
Activated protein C (APC) is a serine protease with anticoagulant, anti-inflammatory, and cytoprotective properties. Using recombinant APC, we identified a class of single-stranded DNA aptamers (HS02) that selectively bind to APC with high affinity. Interaction of HS02 with APC modulates the protease activity in a way such that the anticoagulant functions(More)
OBJECTIVE Nuclear transfer-embryonic stem cells (NT-ESCs) are genetically identical to the donor's cells; provide a renewable source of tissue for replacement, and therefore, decrease the risk of immune rejection. Trichostatin A (TSA) as a histone deacetylase in- hibitor (HDACi) plays an important role in the reorganization of the genome and epigenetic(More)
