In multiple sclerosis Oligodendrocytes are obliterated by the immune system. neural stem/ progenitor cells (NS/P Cs) have the capacity to differentiate into mature myelinating oligodendrocytes. In embryonic mouse cortex oligodendrocyte progenitor cells (OPCs) are more abundant than the ganglionic eminence. Doing gene set enrichment analysis using DAVID and Panther websites it was shown that Gpr...

Objective: Behcet's disease (BD) is a chronic inflammatory disorder characterized by recurrent oral and genital aphthous ulcers, uveitis and skin lesions. Oxidative stress and inflammation have important role in the pathogenesis of BD. The aim of this study was to assess the effect of Nigella sativa (NS) oil administration on malondialdehyde (MDA), total anti-oxidant c...

objective: nanotechnology focuses on materials having at least one dimension of less than 100 nanometers. nanomaterials such as nanosilver (ns) have unique physical and chemical properties such as size, shape, surface charge. ns particles are thought to induce neuronal degeneration and necrosis in the brain. it has been reported that ns particles generate free radicals and oxidative stress whic...

The aim of this work, to estimate the External exposure, ingestion Exposure and inhalation exposure dose rate from gamma ray released from Natural Radionuclides in cultivated, uncultivated and phosphate soil samples in the area surrounding EL-Naser Factory for phosphate in El-Mahamid, Idfu, Aswan, Upper Egyp by using modeling, this model studied the exposure gamma radiation from different natur...

An analytical procedure was proposed for the determination of 226 Ra at ultratrace levels in sand filters using sector field inductively coupled plasma mass spectrometry (ICP-MS). Radium was preconcentrated using an impregnated manganese dioxide filter and separated from strontium using Eichrom“Sr-resin.” Following the extraction chromatography, polyatomic ions of Pb and W were eliminated by op...
