A randomized double blind comparison of atosiban in patients with recurrent implantation failure undergoing IVF treatment.

Background: Patients with recurrent implantation failure (RIF) may have more uterine contractions. Several observational studies suggested that atosiban administration around embryo transfer resulted in higher pregnancy rates in RIF patients. This study aimed to evaluate the effect of atosiban given before fresh embryo transfer on pregnancy outcomes of women with RIF.

Critical cultural competence of clinical nurses in China: A cross-sectional survey.

Aim: To determine the level of critical cultural competence (CCC) among Chinese clinical nurses and explore its influencing factors.

Background: Previous research has only focused on the theoretical model of CCC and the development of assessment tools; however, no large-scale study has been conducted on the level of clinical nurses' CCC and its influencing factors.

Method: Clinical nurses in 14 Level A tertiary hospitals (n = 3858) were surveyed using Almutairi's critical cultural competence scale (CCCS).

Cyclosporin A protects JEG-3 cells against oxidative stress-induced apoptosis by inhibiting the p53 and JNK/p38 signaling pathways.

Background: Trophoblast cells are required for the establishment of pregnancy and fetal development. Apoptosis is an essential feature for trophoblast invasion. Uncontrolled trophoblast apoptosis is related to some complicate pregnancies.

Analysis of the interaction of tarantula toxin Jingzhaotoxin-III (β-TRTX-Cj1α) with the voltage sensor of Kv2.1 uncovers the molecular basis for cross-activities on Kv2.1 and Nav1.5 channels.

Animal venoms contain a fascinating array of divergent peptide toxins that have cross-activities on different types of voltage-gated ion channels. However, the underlying mechanism remains poorly understood. Jingzhaotoxin-III (JZTX-III), a 36-residue peptide from the tarantula Chilobrachys jingzhao, is specific for Nav1.

Negative regulation of Vsx1 by its paralog Chx10/Vsx2 is conserved in the vertebrate retina.

Chx10/Vsx2 and Vsx1 are the only Paired-like CVC (Prd-L:CVC) homeobox genes in the mouse genome. Both are expressed in the retina and have important but distinct roles in retinal development. Mutations in Chx10/Vsx2 cause reduced retinal progenitor cell (RPC) proliferation and an absence of bipolar cells, while mutations in Vsx1 impair differentiation of cone bipolar cells.

Isolation of a glial-restricted tripotential cell line from embryonic spinal cord cultures.

Neuroepithelial stem cells (NEPs), glial-restricted precursors (GRPs), and neuron-restricted precursors (NRPs) are present during early differentiation of the spinal cord and can be identified by cell surface markers. In this article, we describe the properties of GRP cells that have been immortalized using a regulatable v-myc retrovirus construct. Immortalized GRP cells can be maintained in an undifferentiated dividing state for long periods and can be induced to differentiate into two types of astrocytes and into oligodendrocytes in culture.
