A nuclear polyhedrosis virus isolated from infected Bombyx mori, BmNPV, was used to inoculate silkworms to determine salivary gland cell susceptibility. The salivary gland was removed from infected silkworms at different times post-inoculation and examined by light microscopy. The salivary gland cells did not exhibit any signs.. Read More»

B chromosomes, also called supernumerary or accessory chromosomes, have been characterized as extra elements found in the karyotypes of different eukaryotic species. B chromosomes are nonvital and only occur in some individuals within a species. Moreover, the chromosomes contain silenced genes, and they exhibit heterochromatinization and the accumulation ..

In the present study, the tissue-specific and temporal gene expression profiles of four catalogues of gonadal development-related genes (sex differentiation-related, steroid receptor, steroidogenic, and structural genes) were detected in nine tissues and during 11 successive developmental stages in the Pengze crucian carp (Pcc..

The growth arrest-specific 6 gene (GAS6) is a member of the family of plasma vitamin K-dependent proteins, which are able to bind to phospholipids using an N-terminal gamma-carboxyglutamic acid domain. A recent report has demonstrated that the GAS6 gene can promote fat deposition and is associated with an increased number of fat cells in mice. In order to.. Read More»

Porcine epidemic diarrhea poses significant sanitation problems in the porcine industry, and has negatively affected the economy in recent years. In this study, 48 fecal specimens were collected from piglets from four intensive swine farms located in the Gansu Province of China. The molecular diversity and phylogenetic relatio.. Read More»

DNA sequence diversity in the tRNAleu-COII portion of the mitochondrial genome was investigated in samples of Apis cerana from Yunnan, China. A fragment of about 480 bp in tRNAleu-COII, including a noncoding area and part of COII, was sequenced. The noncoding area was 97-98 bp; 8 haplotypes were found, among which 5 had been reported previously, while 3 w.. Read More»

The aim of this study was to investigate the abilities of cartilage-derived morphogenetic protein 1 (CDMP1) transgenic cell sheets in repairing rabbit cartilage defects. Rabbit CDMP1 transgenic bone marrow mesenchymal stem cell (BMSC) sheets (CDMP1-BMSCs) were cultured on temperature-sensitive culture dishes, and CDMP1 expression and type II collagen prot..

We investigated the effect of neural stem cells (NSC) and erythropoietin (EPO) on axon regeneration in adult rats with transected spinal cord injury, and provided an experimental basis for clinical treatment. Forty Wistar rats with T10-transected spinal cord injury were randomly divided into four groups of ten rats: a control group (group A), an NSC-trans.. Read More»

Previous study has indicated that exposure to anesthesia in early development leads to neuro-apoptosis and is followed by long-term cognitive dysfunction. Given that larger numbers of pregnant women currently receive anesthesia during the first trimester, we wanted to mimic this process in vitro using mouse embryonic stem cells (mESCs) and to explore how ..

A joint growth-carcass model using random regression was used to estimate the (co)variance components of beef cattle body weights and carcass quality traits and correlations between them. During a four-year period (1994-1997) of the Australian “southern crossbreeding project”, mature Hereford cows (N = 581) were ma.. Read More»
