BACKGROUND CD4(+)CD25(+) regulatory T cells (Tregs) are important for the maintenance of immune homeostasis by virtue of their ability to control T-cell proliferation in the peripheral blood (PB). We recently demonstrated that the prevalence of Tregs is decreased, whereas that of Th17 cells is increased, in the PB and decidua samples of patients with unexplained recurrent miscarriage (RM). In t...

Enzyme engineering has been facilitated by recombination of close homologues, followed by functional screening. In one such effort, chimeras of two class-A β-lactamases - TEM-1 and PSE-4 - were created according to structure-guided protein recombination and selected for their capacity to promote bacterial proliferation in the presence of ampicillin (Voigt et al., Nat. Struct. Biol. 2002 9:553)....

PURPOSE Health care initiatives focusing on prenatal testing and premarital genetic screening aiming to reduce the incidence of β-thalassemia have emerged during the last decade. In Palestine, 4% of the population are known thalassemia carriers with new cases continuing to appear despite the availability of prenatal testing. This study aims to identify factors that influence the decision to ret...

The aim of this study was to evaluate the concentrations of reproductive hormones in blood plasma and in follicular fluids of different sized follicles during various stages of the estrous cycle in Holstein cattle. Jugular blood samples from 42 adult Holstein cattle were collected immediately after the slaughter. Antral fluids from small (4-5 mm), medium (6-9 mm) and large (10-20 mm) follicles ...

BACKGROUND AND OBJECTIVE The association between sleep and obesity has been described in different age groups. However, there are not sufficient data to clarify the inconsistent results reported in adolescents. Our objective was to study the associations between sleep duration and adiposity at 13 and at 17 years of age, with both cross-sectional and longitudinal approaches. METHODS We evaluat...
