Background
Bcl11b, previously CTIP2, is a zinc finger nuclear transcription factor involved in the development of keratinocytes, teeth, T lymphocytes, and nervous tissue. Expression of Bcl11b has been reported in human head and neck squamous cell carcinoma (HNSCC) and increased expression correlates with poorly differentiated tumors. This study aimed to...
Cobalamin (vitamin B12) is a water-soluble vitamin that plays a role as an indicator of gastrointestinal disease in dogs. In addition, supplementation of vitamin B12 to dogs deficient in cobalamin has been shown to improve clinical signs of intestinal disease.1,2 Low serum cobalamin has been found in dogs with food-responsive,...
An integral component to understanding lithospheric rheology, fault mechanics, and geodynamic processes is knowledge of the subsurface thermal regime. This study presents thermal data from 26 new borehole sites drilled during the installation of borehole strain meters as part of the Plate Boundary Observatory (PBO). These data extends existing coverage...
Ultrastructural analysis and chemical inhibition studies were
carried out on first cleavage of Mytilus zygotes to determine possible
relationships between the mitotic apparatus and the cortex during
polar lobe formation.
The stages of mitosis correlated with the appearance of the
polar lobe were first determined by light microscopy. The polar...
Oogenesis in the sea urchin Strongylocentrotus purpuratus was
studied at the fine structural level, with special emphasis on the relationship
between the two main cell types within the ovary: the egg cells
and the nutritive phagocytes, or accessory cells. The nutritive
phagocytes are flagellated cells with extensive pseudopods which store...
The gastrula of the sea urchin Strongylocentrotus purpuratus
was dissociated into single cells. In culture these cells appeared
apolar, but reassembled into quasi-normal embryos composed of
structures with polarized cells. In this study emphasis was placed on
those morphological events coincident with the reestablishment of a
polar orientation within the...
The objective of this project was, "To establish, in Oregon, a coastwide red abalone sport fishery and a limited commercial fishery as stocks dictate." Starting in 1967, abalone were planted at Whale Cove in Lincoln County, and were later planted at the Rogue River Reef in the Gold Beach area...
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...
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...
Oögenesis in the sea urchin Strongylocentrotus purpuratus
was studied by histological methods and by histochemical techniques
for polysaccharides, lipids, and nucleic acids Urchins were
collected at Yaquina Head, Oregon at regular intervals between
April 1966 and March 1967. An attempt was made to correlate
seasonal variations in the coastal water...
