The hypothesis of preimplantation genetic diagnosis (PGS) was first proposed 20 years ago, suggesting that elimination of aneuploid embryos prior to transfer will improve implantation rates of remaining embryos during in vitro fertilization (IVF), increase pregnancy and live birth rates and reduce miscarriages. The aforementioned improved outcome was based on 5 essential assumptions: (i) Most I...

Brush-type macromolecules (BMs) have attracted much attention over the past decades because of their unique properties and potential applications in nanoscience, drug-delivery systems, photonics. A two-step strategy synthesis polycarbonate-grafted copolymers with either star-shaped or brush-typed morphologies using a “grafting from” approach is reported; backbone these all-polycarbonate graft m...

The convection-permitting regional climate model CNRM-AROME was applied on a spatial domain restricted to the northern half of France for analyzing its performances in simulating urban Paris region, and potential added value compared CNRM-ALADIN. In addition fine horizontal resolution (2.5 km 12.5 CNRM-ALADIN), has advantage integrating canopy TEB into land-surface modeling system. A hindcast s...

The aim of the present study was to analyse physicochemical properties and chemical composition soil after years applying varied tillage systems pre-crops. field experiments were carried out in Lipnik Poland. experiment conducted over 25 years, with factor I–3 systems: ploughing (A), ploughless (B) direct sowing (C), II-pre-crop–1–faba bean, 2–sugar beet. Simplified used, increased acidity foun...

one of the important subjects of comparative literature_ in french school_ is studying common contents between literature of different languages and separating literati’s initiatives and borrowing from other authors in the same or another language by them. with this aspect. using analytic – comparative metod, this study compares poems of abu tayyib al-muttanabbi_ as one of the most impressive a...

The increased use of blastocyst transfer has emphasized the importance selecting high-quality embryos. Analyses embryos in a time-lapse incubator system showed that zygotes with shortest intervals between first and second or third mitotic divisions were higher rate. Additionally, developed relatively faster to morulae blastocysts had implantation rates. However, useful indicators predict which ...
