We performed a prospective randomized clinical trial to investigate whether long distance oocyte transport prior to an intracytoplasmic sperm injection (ICSI) procedure influences fertilization rates, embryo quality and/or embryo implantation rates. After informed consent, 100 infertile couples booked for ICSI treatment were randomized into two groups. In group 1 (n = 50), patients were stimula...
BACKGROUND We have previously reported the retrospective observation that when at least one embryo, transferred on day 3, expressed sHLA-G above the geometric mean (sHLA-G+) 46 h post-ICSI, there was a marked improvement in both pregnancy (PR) and implantation (IR) rates. METHODS The media surrounding individual embryos derived from ICSI performed on oocytes from 482 women < or =43 years of a...
In vitro regeneration of two cultivars of carnation, namely, ‘Nelson’ and ‘Impulse’ was studied through direct somatic embryogenesis. Somatic embryos were formed directly on petal explants cultured on Murashige and Skoog (MS) medium containing different concentrations (0.2, 0.5, 1, 2, 4, 6 mg 1-1) of picloram. Maximum embryogenesis was obtained with 1 and 2 mg/l picloram. Globular shaped embryo...
A total of 41 patients requested thawing of supernumerary embryos in an intracytoplasmic sperm injection (ICSI) programme. Mean patient age was 30.8 +/- 3.8 years. Embryo freezing by the ultrarapid method was performed at room temperature in 3 mol/l DMSO and 0.25 mol/l sucrose. Total freezing time was 2.5 min including filling of the straw. In the thawing process, the embryos were removed from ...

abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
P-101: Effects of Ethanol and Strontium on Growth and Development of Two-Cell Arrested Mouse Embryos
Background: Arresting in a certain step of development like two-cell stage could be one of the reasons of infertility. The aim of this study is evaluating the effects of ethanol and strontium on growth and development of two-cell arrested mouse embryos. Materials and Methods: The females were coupled with male following superovulation. Positive vaginal plug mice were killed 48 hours after hCG i...
the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
