Histochemical Studies on the Hypothalamo-hypophysial Neurosecretory System. III. Vitamin C, Phosphatase, Peroxydase and Zinc

Hypothalamo-hypophysial control of ovulation in the vole (Microtus agrestis).

Electrical stimulation of the anterior hypothalamus of the vole, Microtus agrestis, usually results in ovulation, whereas stimulation of areas in the posterior hypothalamus do not. Ovulation can also be elicited by injections of sheep median-eminence extracts, and by preparations ofsheep luteinizing hormone. Observations on the number of corpora lutea formed, and ripe Graafian follicles remaini...

Histochemical and biochemical studies on leukocyte alkaline phosphatase activity.

History of the neurovascular concept of hypothalamo-hypophysial control.

It is indeed a great honor to be selected by the Society to receive the Hartman Award and I am most grateful. 1 was an ardent admirer of Carl Hartman from the time I first met him in the early ‘40’s at Stanford University. He was a personal friend of Joe Markee with whom I worked and whom 1 accompanied to Duke University and I had the benefit of numerous discussions while Hartman was visiting M...

Developmental changes in gonadotropin-inhibitory hormone in the Japanese quail (Coturnix japonica) hypothalamo-hypophysial system.

We previously isolated a novel dodecapeptide containing a C-terminal -Arg-Phe-NH(2) sequence, SIKPSAYLPLRF-NH(2) (RFamide peptide), from the Japanese quail (Coturnix japonica) brain. This novel quail peptide was shown to be located in neurons of the paraventricular nucleus (PVN) and their terminals in the median eminence (ME), and to decrease gonadotropin release from cultured anterior pituitar...

Adsorption of Vitamin C on a Fullerene Surface: DFT Studies

Density functional theory (DFT) calculations were performed to investigate adsorptions of vitamin C (Vit) on the surface a fullerene structure (Ful) in gaseous and water–solvated systems. Two models of Vit including OVit and MVit were created based on the original structure of Vit for OVit and methylation of all hydroxyl groups for MVit. All singular and hybrid structures were optimized and the...
