Dermatoglyphic total patterns on palms, finger-tips and soles in twins. | 110 palms of MZ twins and 111 like-sexed pairs of DZ twins have been compared in respect of a concordance rate of the palmar, sole and finger-tip total pattern types. Dermatoglyphic patterns have been classified according to the topological method, and the distributions of the numbers of discordant pattern elements fro... | 569,454 | [

Functions of cytoplasmic fibers in intracellular movements in BHK-21 cells. | After trypsinization and replating, BHK-21 cells spread and change shape from a rounded to a fibroblastic form. Time-lapse movies of spreading cells reveal that organelles are redistributed by saltatory movements from a juxtanuclear position into the expanding regions of cytoplasm. Bidirectional saltations are seen alo... | 569,659 | [
