Lipid rafts are small laterally mobile microdomains that are highly enriched in lymphocyte signaling molecules. GM1 gangliosides are a common lipid raft component and have been shown to be important in many T-cell functions. The aggregation of specific GM1 lipid rafts can control many T-cell activation events, including their novel association with T-cell integrins. We found that clustering GM1...
Novel Mg (0.58, 0.97, 1.98 and 2.5) vol. % TiN nanocomposites containing titanium nitride (TiN) nanoparticulates of ~20 nm size are successfully synthesized by a disintegrated melt deposition technique followed by hot extrusion. Microstructural characterization of Mg-TiN nanocomposites indicate significant grain refinement with Mg 2.5 vol. % TiN exhibiting a minimum grain size of ~11 μm. X-ray ...
INTRODUCTION Zambia is facing a chronic shortage of health care workers. The paper aimed at understanding how the Medical Education Partnership Initiative (MEPI) program facilitated strengthening and expanding of the national capacity and quality of medical education as well as processes for retaining faculty in Zambia. METHODS Data generated through documentary review, key informant intervie...
This paper presents seven ‘theses’ that capture some important theoretical, methodological and empirical trends regarding research on happiness, and, more in general, theoretical economics and policy making. The trends concern: (1) the advent of new neuroscience techniques and the strengthening of existing ones: these are producing sound knowledge on animals’ and people’s brain mechanisms under...
Orientation selectivity (OS) of visual cortical neurons is progressively sharpened during development. However, synaptic circuit mechanisms underlying the OS sharpening remain unclear. In the current study, in vivo whole-cell voltage-clamp recordings from layer 4 excitatory neurons in the developing mouse primary visual cortex revealed changes of orientation tuning profiles of their excitatory ...
