Effects of different polyvinylpyrrolidone concentrations on intracytoplasmic sperm injection

SummaryTo explore whether different polyvinylpyrrolidone (PVP) concentrations affect the results of intracytoplasmic sperm injection (ICSI), a prospective study was conducted for 194 couples undergoing 210 ICSI therapy cycles. These cycles were divided into three groups (10, 7 and 5% groups) using the corresponding concentration of PVP for sperm immobilization. The main outcome measures were analyzed. Results indicated that, with a decrease in PVP concentrations, all of the main outcome measures increased. In particular, the high-quality cleavage embryo rate in the 7% group was significantly lower than in the 5% group (P < 0.01), and the cleavage, high-quality cleavage embryo, and high-quality blastocyst rates in the 5% group were significantly higher than those in the 10% group (all P < 0.001). For high-/intermediate-quality semen, all of the main outcome measures were significantly increased with 5% PVP. For the poor-quality semen, only the high-quality cleavage embryo and high-quality blastocyst rates were significantly higher in the 5% group. Therefore, lowering PVP concentrations greatly promoted the development of embryos in ICSI cycles, with an optimal concentration of 5% for ICSI.

The Poor

Six cuprous oxide antifouling paints, ranging from low to high quality, were exposed to settling larvae of Spirorbis lamellosa Lamarck and S. convexis Wisely. All paints were newly immersed (up to 11 days). The poor quality paint allowed larvae to attach under laboratory conditions or in the sea, and these larvae developed the characteristic spiral tubes of the adults before dying (post-attachment mortality). Under similar conditions the intermediate and high quality paints killed the larvae before they could attach (pre-attachment mortality). These results are compared with those obtained recently for barnacle, bryozoan, and bivalve mollusc larvae.

A Prospective Study

ABSTRACT Introduction In assisted reproduction technique cycles, controlled ovarian stimulation (COS) leads to supraphysiological levels of steroid hormone secretion and the subsequent need for luteal phase support (LPS). Therefore, existing data on the steroid secretion profile in the luteal phase of spontaneous conception cycles and its predictive value for pregnancy outcome need to be discussed against the background of preceding COS. The clinical significance of luteal phase hormones, such as estrogen (E2) and progesterone (P4), in predicting pregnancy after controlled ovarian hyperstimulation protocols for in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is still poorly understood. The aim of the present study was to investigate the role of midluteal serum E2 and P4 level in predicting successful pregnancy in patients undergoing IVF/ICSI. Materials and methods One hundred fifteen women were recruited for the study. They were given gonadotropin-releasing hormone antagonist protocol and human chorionic gonadotropin (hCG) was administered if at least three follicles were more than 18 mm in size. Transvaginal ultrasound-guided oocyte retrieval followed by ICSI and embryo transfer (ET) was done. Post-ET, all women had same LPS. The E2 and P4 measurements were done at day of ET (day 0) and 9 days post-ET (day 9). Levels of E2 and P4 were compared between those who subsequently became pregnant and those who could not achieve pregnancy. Statistical analysis was performed using Statistical Package for the Social Sciences. Results Forty-six (40%) achieved pregnancy. The E2 and P4 levels on day 9 were significantly higher in those who achieved pregnancy (p < 0.01). Out of 46 pregnancies, 38 were ongoing viable pregnancies. Conclusion Luteal phase E2 and P4 can be used as prognostic marker to predict pregnancy in IVF/ICSI cycles. How to cite this article Nigam S, Joy I, Shankar K, Varma TR.

A comprehensive field data were collated analyzed and processed for the validation of open source bathymetry data GEBCO 30 sec arc resolution data in the selected location of the Red sea. Different software and techniques were used to verify the quality of GEBCO data in the field conditions. The image analysis using different software proves the poor quality and resolution of the GEBCO data in the nearshore areas. The analyses also brought out the complex topographical nature of the Red sea and precautions for the usage of open source bathymetric data in the nearshore areas of the Red sea, where high quality and fine resolution data required. The different statistical analyses also verified the results of image analysis. The statistical analysis also shows the poor quality and course resolution of the GEBCO 30sec resolution data in the Red sea especially nearshore areas. The study recommends hydrographic survey data for the nearshore areas, where high quality and resolution data are needed

The 19Th Century

Benefiting from the consequences of cultural and scientific development which kicked off in the 19th century, the Romanian space also felt the lags up till then. The development and organisation deficit of science and culture, the poor quality of their relationships with the social complex, were augmented frequently not necessarily by the poor quality of the Romanian scholars, but by a certain superficiality of theirs in the approach and presentation of the treated matters. Trying to confer reliability, accuracy and transparency to the scientific construction in which he took part, A. Philippide often felt in a negative manner some of the scientific behaviours and results presented by his generation colleagues. In this context, beyond the high quality of his results and his highly responsible attitude, the way in which the scholar from Iași tried to improve the process was the scientific polemic.
