It has been proposed that the CD7 molecule is the first antigen expressed on the membrane of cells committed to the T-cell lineage during human fetal T-cell ontogeny. To further identify the pre-T cell subpopulation that migrates to the thymus early in ontogeny, we analyzed the phenotypic and functional characteristics of the fetal liver populations separated on the basis of CD7 expression. Thr...

The CB1 cannabinoid receptor has been implicated in the regulation of bone remodeling and bone mass. A high bone mass (HBM) phenotype was reported in CB1-null mice generated on a CD1 background (CD1 / mice). By contrast, our preliminary studies in cb1 / mice, backcrossed to C57BL/6J mice (C57 / mice), revealed low bone mass (LBM). We therefore analyzed CB1 expression in bone and compared the sk...

background: to ascertain the effects of tropical leaf meals on semen production and semen quality. objective: this study was conducted with the main objective of investigating the effect of neem leaf meal on physiological responses of rabbit bucks fed graded levels of neem leaf (azadirachta indica a. juss) meal. materials and methods: the varying levels of neem leaf meal (nlm) in the different ...

Abstract Most probiotic yeast supplement in fish exhibit beneficial effect at ≤1% of the dietary proportion. This study aimed evaluating specific effects Lypomyces starkeyi CB180 7 strain supplemented proportion on performance juvenile red sea bream ( Pagrus major , 1.9 ± 0.04 g). Five diets were with graded levels 0% (control diet ‘CD1’), 0.05% (D2), 0.1% (D3), 0.5% (D4), and 1.0% (D5). After ...

Three-dimensional (3D) Dirac semimetal materials have great application prospects in broad-spectrum photodetectors (PDs) working at wavebands up to the mid/far infrared region owing their unique topological energy-band architectures and excellent photoelectric properties. However, relatively high dark current most semimetal-based PDs limits photodetection performance, with poor signal-to-noise ...

The experiments described in this article characterize the phenotypic and functional changes in afferent lymph cell populations that occur as a result of in vivo immune stimulation. During the primary immune response (in antigen-naive sheep) there are very transient increases in level of CD1 expression by subpopulations of dendritic cells (DC) but no alterations in cell kinetics or MHC class II...

A universal theoretical model is proposed that explains the observed shift of IR absorption and emission bands in spectra transition metal ions solid solutions semiconductor compounds. The has been used for estimating long-wavelength luminescence with increasing concentration application to crystals ternary systems Zn1 – xMgxSe:Cr2+ Cd1 xMnxTe:Fe2+. Description phenomenon generalized case multi...
