embryonic stem cells (escs) are originally derived from the icm of blastocysts and are characterized by their ability to self-renew and their pluripotencies. only a few reports have been published on esc isolations and line establishment in animals, even fewer in horses. however, it is still important to isolate equine escs for animal biotechnology and therapeutic applications. in the present s...

One hundred and twenty-four erythromycin-resistant pneumococcal isolates were examined for the presence of macrolide resistance genes. The erm(B) gene was detected in 118 (95.2%) isolates and the mef(A) gene in 83 (66.9%) isolates. Both the mef(A) and erm(B) genes were detected in 77 (62.1%) isolates. DNA macrorestriction analysis of these isolates identified them as belonging to a single multi...

Introduction Pectinolytic enzymes are of great importance for the clarification process “Vinho Verde” wine must, contributing to reduction haze development. During last decade, a growing body knowledge has been established about effects electric fields on activation important food enzymes. However, influence electrical parameters catalytic activity is enzyme-dependent and should be evaluated ca...

Erythromycin-resistant Streptococcus pneumoniae isolates from young carriers were tested for their antimicrobial susceptibility; additionally, inducibility of macrolide and clindamycin resistance was investigated in pneumococci carrying erm(A), erm(B), or mef(A). Of 125 strains tested, 101 (81%) were multidrug resistant. Different levels of induction were observed with erythromycin, miocamycin,...

Moderate electric field (MEF) was employed to sunflower protein isolate (SPI) and sodium caseinate (CAS) change their structural thermo-physical properties with a non-thermal approach. MEF treatment significantly reduced the average particle size noticeable changes in uniformity of SPI CAS solutions. A maximum 10% reduction surface tension observed for 0.2% w/w sample by applying 150 V 20 s. Th...

Aberrant regulation of glycogen synthase kinase-3 (GSK-3) is implicated in Alzheimer's disease (AD), but the mechanisms involved remain elusive. Our recent study shows that GSK-3 impairs lysosomal acidification and that inhibition of GSK-3 re-acidified lysosomes in brains of AD mice. This effect was accompanied by reductions in β-amyloid pathology and amelioration of cognitive deficits. Preseni...

this study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. one-cell mouse embryos were obtained from nmrimice after superovulation by an intraperitoneal injection of 5 iu equine chorionic gonadotrophin (ecg)followed 48 hrs later by 5 iu human chorionic gonadotrophin (hcg). mouse embryonic fibrobla...

Identifying potential adverse drug reactions (ADRs) is critically important for drug discovery and public health. Here we developed a multiple evidence fusion (MEF) method for the large-scale prediction of drug ADRs that can handle both approved drugs and novel molecules. MEF is based on the similarity reference by collaborative filtering, and integrates multiple similarity measures from variou...

In bone marrow, the differentiation of osteoblasts and adipocytes is reciprocally regulated. This inverse regulation occurs mainly through complex signaling crosstalk between transcriptional factors such as peroxisome proliferator-activated receptor-γ (PPARγ) and runt-related transcription factor 2 (Runx2). This commentary addresses the role of myeloid elf-1 like factor (MEF) and distal-less ho...

The Social Security Administration (SSA) receives reports of earnings for the U.S. working population each year. Earnings data are used to administer the Social Security programs and to conduct research on the populations served by those programs. The administrative needs of SSA and other agencies have changed over time and, as a result, there have been numerous changes to the main source of SS...
