Submicroscopic Morphology of Protoplasm
SUBMICROSCOPIC MORPHOLOGY OF PROTOPLASM. By A. Frey-Wyssling. 2d English Ed. Houston, Elsevier, 1953. 411 pp., 181 figs. $8.00. This is really the third edition of Frey-Wyssling's famous monograph, for the first English edition (1948) was actually a revision of the original German edition (1938). Following an orienting introduction, the book is divided, as in previous editions, into three parts...
متن کاملThe submicroscopic morphology of Gaucher cells.
IT IS the purpose of this paper to describe the submicroscopic morphology of the large cells characteristic of Gaucher’s disease. Electron micrographs of sternal bone marrowbiopsy specimens from three patients with Gaucher’s disease are presented. For comparison we have included descriptions of the cells as cxamined in Wright’s stained preparations with the bright field microscope, and unstaine...
متن کاملSome Features of the Submicroscopic Morphology of Synapses in Frog and Earthworm
Electron micrographs are presented of synaptic regions encountered in sections of frog sympathetic ganglia and earthworm nerve cord neuropile. Pre- and postsynaptic neuronal elements each appear to have a membrane 70 to 100 A thick, separated from each other over the synaptic area by an intermembranal space 100 to 150 A across. A granular or vesicular component, here designated the synaptic ves...
متن کاملSubmicroscopic Deterministic Quantum Mechanics
So-called hidden variables introduced in quantum mechanics by Louis de Broglie and David Bohm have been revived in the recent works by the author. However, the variables, as such, have changed their initial enigmatic meanings and acquired quite reasonable outlines of real and measurable characteristics. The success in the deepest description of quantum systems becomes possible due to the detail...
متن کاملElectron Microscopic Observations on the Submicroscopic Morphology of the Meiotic Nucleus and Chromosomes
Thin sections of the testicular follicles of the grasshopper Laplatacris dispar were studied under the electron microscope. In the primary spermatocytes, during meiotic prophase, three main regions can be recognized within the nucleus: (1) the nucleolus and associated nucleolar material; (2) the interchromosomal regions with the dense particles; and (3) the chromosomes. The nucleolus is general...
