Abstract:
:We studied changes in cell cycle and apoptosis in normal keratinocytes and melanocytes after exposure to UV-B radiation. UV-B radiation modulated proliferation rate in the studied cell and produced an apoptosis-modulating effect in epidermal melanocytes.

杂志文章abstract::Tropomyosin (Tpm) is one of the main regulatory proteins in the myocardium. In some heart pathologies, interchain disulfide crosslinking in the Tpm molecule occurs. In the ventricle, this change in the structural properties of the Tpm molecule affects calcium regulation of the actin-myosin interaction. Using an in vit...
