BACKGROUND Several studies suggest that defects of regulatory T-cells (Tregs) and impaired cellular immunity are secondary to an imbalance between auto-aggressive T-cells and Tregs in lupus patients. Discrepancies in Tregs and effector T-cells (Teff) in active lupus patients are shown to be restored in patients upon receiving immunosuppressive therapy. Therefore, our main aim was to observe fre...

The study was conducted in Assosa district of Benishangul-Gumuz regional state, western Ethiopia, to assess major farm enterprises, agricultural risks and demand for micro-insurance services. Two peasant associations namely, Selga-23 and Kushmengel were selected to represent settler and native farming communities, respectively. Using simple randomized techniques, 86 respondents were selected fo...

Tumor infiltration with effector CD8þ T cells (Teff) predicts longer recurrence-free survival in many types of human cancer, illustrating the broad significance of Teff for effective immunosurveillance. Colorectal tumors with reduced accumulation of Teff express low levels of Teff-attracting chemokines such as CXCL10/IP10 and CCL5/RANTES. In this study, we investigated the feasibility of enhanc...

We report the discovery of two new ZZ Ceti pulsators, LP 133−144 and HE 1258+0123, selected on the basis of model atmosphere fits to optical spectroscopic data. The atmospheric parameters for LP 133−144, Teff = 11, 800 ± 200 K and log g = 7.87 ± 0.05, and for HE 1258+0123, Teff = 11, 410 ± 200 K and log g = 8.04 ± 0.05, place them within the empirical boundaries of the ZZ Ceti instability strip...

Published pre-Fukushima food monitoring data from 1963 to 1995 were used to study the long-term presence of 137Cs and 90Sr in rice and wheat. Effective half-lives (Teff) were calculated for rice (137Cs: 5.6 years; 90Sr: 6.7 years) and wheat (137Cs: 3.5 years; 90Sr: 6.2 years), respectively. In rice, 137Cs exhibits a longer Teff because putrefaction processes will lead to the formation of NH4+ i...

a sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (mwcnt/gce), was developed for determination of fenitrothion. determining the surface area of mwcnt/gce showed that this surface is three times more active than that of a glassy carbon electrode. the experimental parameters, such as the amount of mwcnts, ph of the fenitrothion solution, preconcentration potential an...

Abstract Background Teff is a warm-season cereal crop and the tiniest grain on planet. It one of underutilized crops that can contribute to food security diversification. nutritious well adapted growing conditions in Ethiopia, but little has been invested expand its potential domestic or international markets. Method Comprehensive empirical review was carried out emphasizing spatial, temporal p...

Context. The discovery of the Spite plateau in the abundances of 7Li for metal-poor stars led to the determination of an observationally deduced primordial lithium abundance. However, after the success of the Wilkinson Microwave Anisotropy Probe (WMAP) in determining the baryon density, ΩBh, there was a discrepancy between observationally determined and theoretically determined abundances in th...
