The objective of this retrospective study was to evaluate the efficacy of vitrification and slow freezing for the cryopreservation of human cleavage stage embryos in terms of post-warming survival rate, post-warming embryo morphology and clinical outcomes. The embryos of 305 patients at cleavage stages were cryopreserved either with vitrification (153(More)
The aim of this study was to determine if laser zona thinning could improve the rates of pregnancy and implantation for vitrified-warmed embryo transfer at the cleavage stage. A total of 400 vitrified-warmed embryo transfer cycles were randomly assigned to either the test group or the control group. The zona pellucida of vitrified-warmed embryos in the(More)
BACKGROUND The aim of this study is to investigate the effect of ISM1 culture medium on embryo development, quality and outcomes of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. This study compares culture medium commonly used in the laboratory setting for oocyte recovery and embryo development with a medium from MediCult. We(More)
OBJECTIVE Chromosomal abnormalities and poor quality are correlated with DNA damage in the pre-implantation stage in humans. This study aimed to explore the altered expression of DNA damage signalling pathways - including apoptosis, cell cycle and DNA repair pathways - in poor-quality pre-implantation human embryos with complex aneuploidy.

This paper reports studies on the effects of re-vitrification by the CPS (Closed Pulled Straw) method on the development of 4-cell stage mouse embryos. The procedure involved culturing 2-cell mouse embryos in G-1 medium until the 4-cell stage followed by the division of the normal 4-cell stage embryos into a control group (non-vitrified) and two(More)
This study evaluates the relationship between sperm intracellular reactive oxygen species (ROS; H2 O2 , O2 ), DNA fragmentation (DF), low mitochondria membrane potential (MMP) of sperm and normal pronuclear formation among intracytoplasmic sperm injection (ICSI) patients. Semen samples were obtained from 62 infertile male who were candidates for ICSI(More)
The two water-soluble designed platinum(II) complex, [Pt(Oct-dtc)(bpy)]NO(3) (Oct-dtc = Octyldithiocarbamate and bpy = 2,2' -bipyridine) and palladium(II) complex, [Pd(Oct-dtc)(bpy)]NO(3), have been synthesized and characterized by elemental analyses, molar conductivity measurements, IR, (1)H NMR, and electronic spectra studies. Studies of antitumor(More)
BACKGROUND Nitric oxide (NO) involves in polycystic ovary syndrome (PCOS), a cause of infertility in women during the reproductive age. The PCOS is now categorized as an inflammatory phenomenon. The aim of this study was to evaluate the role of NO, a proinflammatory agent, in this syndrome at histological and biochemical levels. MATERIALS AND METHODS In(More)
Increasing amount of data and demand to process and analyze them induces enterprises to employ alternative computing paradigms to overcome computing capacity shortages. Cloud Computing is a new emerged computing approach that promises scalability of resources, on-demand availability and pay-as-you-go economic model instead of heavy investment on IT(More)
The software engineering process has been described in many ways. Today, few of these deal specifically with the use of formal methods in software engineering. New software engineering uses formal specification languages in system analysis, requirement analysis, and system design to develop software for critical-safety systems. Formal specification(More)
