The deposition and storage of hepatic lipids in the frog Ascaphus truei (Stejneger) : an electron microscopic histochemical and chromatographic study

Creator:: Belton, John Clair
Abstract:: Electron microscopic, histochemical and thin-layer chromatographic techniques have been used to study some cytological changes associated with seasonal lipid deposition in the liver of Ascaphus. Histochemical and chromatographic information has shown that unsaturated triglycerides occur in great quantities in the liver of pre-ovulatory females and may serve as a solvent...

Fine structure of the interstitial cells of the antebrachial organ Lemur catta

Creator:: Kneeland, Jean Elisabeth
Abstract:: Tissue obtained by punch biopsy from the antebrachial organ of Lemur catta has been studied with the electron microscope. This study describes the fine structure of the interstitial cells found between apocrine sweat glands in the antebrachial organ. These large polygonal cells are of three types: light cells, dark cells,...

The comparative histology of light organs in four Pacific myctophids of the genus, Lampanyctus

Creator:: Wyandt, Herman Edwin, 1939-
Abstract:: A comparative study was made of the morphology and histology of three major groups of light organs in the genus Lampanyctus of the family Myctophidae for the species, L. leucopsarus, L. ritteri, L. nannochir, and L. regalis. The species can be divided according to their ranges in depth, the first...

Study of the human Y chromosome in the interphase nucleus by light microscopy, quinacrine fluoromicroscopy and autoradiography

Creator:: Wyandt, Herman Edwin, 1939-
Abstract:: Part of the Y chromosome in humans is detectable as a brightly fluorescing body in interphase nuclei stained with quinacrine dyes. This fluorescent body when stained with quinacrine mustard dihydrochloride, in cells from some 15 human subjects, was seen to manifest a variable morphology which appeared to be related to...

New perspectives in archosaur biology

Creator:: Harwell, Amy E.
Abstract:: The respiratory and metabolic biology of dinosaurs is poorly, if at all, reflected in the fossil record. By comparing anatomical features of modern taxa that are functionally linked to specific biology with the remains of theropod dinosaurs (Archosauria: Theropoda) and early birds, we may reasonably infer the physiology of long...

New insights into the biology of theropod dinosaurs

Creator:: Quick, Devon E.
Abstract:: There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...

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...

Life cycle and host specificity of Diclidophora sp. (Monogenea-Diclidophoridae), a parasite of embiotocid fishes

Creator:: Hanson, Alfred Warren
Abstract:: The life cycle of a monogenean, Diclidophora sp., was studied with special attention to the time required for developmental stages to occur. Eggs are produced by adult worms at the rate of one every 13.5 minutes and require 32 days to hatch when incubated at 12.5°C and 30.9‰ salinity. Rate...
