Since the antigen affinity of B cells varies from cell to cell, functional analysis in each has been difficult technical aspects. Especially autoimmune diseases, promising pathogenic have not adequately studied date because rarity. Here, we analyzed single-cell function autoantigen-reactive systemic sclerosis (SSc). Topo I-reactive were extracted peripheral blood SSc patients. mRNA expression a...

objective(s): this study focused on determining cytotoxic effects of copper oxide nanoparticles (cuo nps) on chronic myeloid leukemia (cml) k562 cell line in a cell-specific manner and its possible mechanism of cell death. we investigated the cytotoxicity of cuo nps against k562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). materials and methods: the toxicity w...

Plants activate antioxidant defense mechanisms under stress, which help maintaining the structural integrity of cell components and possibly reduces oxidative damage.  Low temperature stress leads to the production of reactive oxygen species and oxidative damage to plants. In this study, the effect of putrescine and proline on reducing the production of reactive oxygen species and increasing th...
