BACKGROUND It has become increasingly apparent that the trophectoderm (TE) at blastocyst stage is much more mosaic than has been appreciated. Whether preimplantation genetic screening (PGS), utilizing a single TE biopsy (TEB), can reliably determine embryo ploidy has, therefore, increasingly been questioned in parallel. METHODS We for that reason here established 2 mathematical models to asse...

ferdous al-hekma book is one of the traditional medicine resources in the islamic civi-lization legacy. ali ibn rabn tabari, its author, has lived in the third century ah. his-torians disagree on the author’s correct name, but the name of ali ibn rabn tabari is of the most interest to them. this name seems more correctly because rabn means “our teacher” in judaism and the author of the book was...

Intracranial stent placement is emerging as an effective treatment for acute stroke. As a means to avoid stent-associated complications and capitalize on stent-placement-related advantages, the concept of a "temporary endovascular bypass" (TEB) for stroke therapy was recently reported. In this technique, a stent is temporarily deployed for instant recanalization. Once sufficient flow is establi...

Thin, amorphous boron-carbon films were deposited at low temperature (400-600 °C) by thermally activated CVD using the organoborane triethylboron (TEB) as a single precursor. Two different carrier gases were tested. At 600 °C using argon as carrier gas the deposition rate was close to 1 μm/h. The film had a density of 2.14 g/cm with a B/C-ratio of 3.7. When hydrogen was used as carrier gas the ...

The root-knot nematode Meloidogyne incognita infects a variety of plants, including Arabidopsis thaliana. During migration, root-knot nematodes secrete different proteins to modify cell walls, which include pectolytic enzymes. However, the contribution of host cell wall proteins has not been described during this process. The function of two DUF642 cell wall proteins, BIIDXI (BDX, At4g32460) an...

Although p120-catenin (p120) is crucial for E-cadherin function, ablation experiments in epithelial tissues from different organ systems reveal markedly different effects. Here, we examine for the first time the consequences of p120 knockout during mouse mammary gland development. An MMTV-Cre driver was used to target knockout to the epithelium at the onset of puberty. p120 ablation was detecte...
