Frequency Of Rickettsia Sps. In Dermacentor Variabilis And Amblyomma Americanum In Central Hanover County, Virginia, Peggy Ann Keefe
Frequency Of Rickettsia Sps. In Dermacentor Variabilis And Amblyomma Americanum In Central Hanover County, Virginia, Peggy Ann Keefe
Master's Theses
In the eastern United States, Dermacentor variabilis is the primary vector of Rickettsia rickettsii, the etiological agent for Rocky Mountain Spotted Fever. Cases of Rocky Mountain Spotted Fever in eastern United States increased steadily from 1959 to 1979 to a peak of one case per 200,000 people in 1979 (Morbidity and Mortality Weekly Report, 1985). In 1976, 98.9% of the reported cases of Rocky Mountain Spotted Fever were east of the 100th meridian with 1.1% occurring west of the 100th meridian (Burgdorfer, 1977). Hanover County, Virginia is an endemic area for this disease (Sonenshine, 1971); the last reported case was …

Pebble Nest Microhabitats Of Semotilus Species (Pisces: Cyprinidae), James Timothy Magee
Master's Theses
The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deepest. Semotilus corporalis used a greater proportion of larger stones (23 mm or greater) in nest construction than the other three species. There was no significant difference in the electivity index (percentage of nest pebble sizes versus those of the substrate) …

Regulatory Cell Biology Of Growth Hormone And Prolactin In The Cow Mammary Gland, David Andrew Walkup
Regulatory Cell Biology Of Growth Hormone And Prolactin In The Cow Mammary Gland, David Andrew Walkup
Master's Theses
Prolactin (PRL) acts directly on milk secretory cell nuclei to stimulate lactation in rats. In the cow, PRL has been detected in Golgi apparatus, endoplasmic reticulum, and secretory vesicle subcellular fractions of mammary gland , but not nuclear fractions. However, growth hormone {GH) is the galactopoeitic hormone in cows, not PRL. The possibility of GH acting directly on the cow milk secretory cells, and PRL acting on their nuclei was investigated using an immunocytochemical method. PRL and GH were detected in endoplasmic reticular and Golgi apparatus regions of the milk secretory cells, as well as, on nuclear and fat globule …
