The fine structure of spermatid differentiation in the mussel, Mytilus edulis, Linn

Creator:: Longo, Frank J., 1939-
Abstract:: The spermiogenesis of Mytilus edulis (a marine mussel) has been studied, employing techniques of light and electron microscopy and cytochemical preparations. The observations trace the development of the acrosomal complex, the nucleus, the mitochondrial middle-piece, and the flagellum. In early spermatids numerous membrane-bounded proacrosomal vesicles arise from several Golgi complexes...

Time-lapse and electron microscope study of cultured epithelium subjected to calcium depletion with EDTA and its subsequent recovery

Creator:: Whitehead, Russell Albert
Abstract:: Primary monolayer cultures of chick renal epithelial cells grown on plastic coverslips were reversibly dissociated with the chelating agent ethylenediaminetetraacetic acid (EDTA). The cellular responses during dissociation and reaggregation in Hank's balanced salt solution (BSS) were observed with phase optics and recorded by time-lapse cinemicrography. The epithelial cells grow as...

A study of powdered corncob as a disintegrating agent in compressed tablets

Creator:: Fakouhi, Taghi
Abstract:: The efficiency of powdered corncob as a tablet disintegrating agent was compared to that of a number of wood products and to starch, the most popular agent used today. Corncob appeared to be superior in its disintegrating effectiveness. The optimum particle size, at which powdered corncob produced its best disintegrating...

Contributions to the plant ecology of the Oregon coastal sand dunes

Creator:: Wiedemann, Alfred M.
Abstract:: Sand dunes are found along the coasts of most of the large land masses of the world. Because of their proximity to man and his activities, the maritime sand dunes of Europe, particularly Germany, France, Holland and Scandinavia, have the longest history of stabilization activities and botanical investigation. There are...
