The dynamic process of the development of the immune system can in itself result in age-related immune malfunctions. In this study, we analysed lymphocyte subsets in the peripheral blood of 60 healthy donors, divided into groups of children, adolescents, and adults, focusing on effector (Teff) and regulatory (Treg) T lymphocytes and STAT1/STAT5 signalling response in helper T lymphocytes (Th) i...

We have established a comprehensive in vivo mouse model for the CD4(+) T cell response to an "innocuous" versus "dangerous" exogenous Ag and developed an in vivo test for tolerance. In this model, specific gene-expression signatures, distinctive upregulation of early T cell-communication molecules, and differential expansion of effector T cells (Teff) and regulatory T cells (Treg) were identifi...

New opacity distribution functions (ODFs) for several metallicities have been computed. The main improvements upon previous ODFs computed by Kurucz (1990) are: (1) the replacement of the solar abundances from Anders & Grevesse (1989) with those from Grevesse & Sauval (1998); (2) the replacement of the TiO lines provided by Kurucz (1993) with the TiO lines from Schwenke (1998), as distributed by...

Antitumor immunity is strongly influenced by the balance of tumor antigen-specific effector T cells (Teff) and regulatory T cells (Treg). However, the impact that vaccine adjuvants have in regulating the balance of antigen-specific T-cell populations is not well understood. We found that antigen-specific Tregs were induced following subcutaneous vaccination with either OVA or melanoma-derived p...

Teff and amaranth are gluten-free cereals with significant nutritional health benefits. However, they underutilized known in limited areas of the world. The present study evaluated fatty acid profile, crude fat, squalene content lipid quality seven teff (Eragrostis (Zucc.) Trotter) three (Amaranthus caudatus L.) varieties from Ethiopia. fat ranged 2.92 to 3.34% (averaging 3.06%) 8.28 9.21% 8.6%...

Teff is one of the major crops grown in central and north western zones Tigray regional state. However, its productivity low due to soil fertility as a result intensive long history cultivation erosion. Therefore, field experiment was carried out on farmer’s Medebay zana Tahtay koraro districts (Adekemalk Beles kebelles) during 2017 2018 main cropping seasons evaluate response NPSZnB fert...

In northwestern Ethiopia, a conventional teff (Eragrostis tef (Zucc.) Trotter) monoculture was converted into rotational agroforestry system (teff-Acacia agroforestry), which consists of the sequence i) teff-Acacia decurrens intercropping (1st year), ii) grass-A. silvopasture (2nd iii) A. plantation (3rd–4th and iv) on-site charcoal production from (end 4th year). This study is first one to com...
