apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing apparently intact organelles. apoptosis occurs in physiological conditions as a regulatory mechanism of tissue growth, where cell proliferation is bal...
enamel matrix derivative emdogain (emd) is widely used in periodontal treatment in spite of the fact that its effect on the developing embryo has not been elucidated. the aim of this study was to investigate the teratogenic effect of emd on the rat embryo neural crest cells. the neural crest is a unique population of cells that migrates from the dorsal neural tube along defined pathways and pro...
The ultrastructure of endogenous stages of Eimeria ninakohlyakimovae was observed in epithelial cells of cecum and colon crypts from a goat experimentally infected with 2.0 x 10(5) oocysts/kg. The secondary meronts developed above the nucleus of the host cell. The nucleus first divides and merozoites then form on the surface of multinucleated meronts. Free merozoites in the parasitophorous vacu...
Introduction: Auger electron based radioimmunotherapy (RIT) using 111In-DOTA-trastuzumab (111In-DOTA-antiHer2) feasibility was studied in vitro on a HER2/neu positive cell line, SkBr3. Methods:111In-DOTA-antiHer2 was prepared according to the optimized conditions followed by quality control tests including radioch...
