Identification Of Actinobacillus Spp Cell-Surface Antigens Using Monoclonal Antibodies, Kall S. Symons

Undergraduate Honors Capstone Projects

Though a senior project is required for graduation from U.S.U. with the Honors Program, there are no written guidelines describing the requirements of a U.S.U. Honors Senior Project. This proposal seeks to show how the present research project from the College of Agriculture should meet the intended project requirements of the Honors Director.

Comparative Study Of Elongated Chromosomes In Sheep And Goats And A Proposed Standard, Stephen H. Mensher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A cell synchronization technique was used that consistently yielded numerous elongated chromosomes, which are necessary for producing high-resolution G-banding. The prometaphase stage of contraction was determined to have the greatest utility for detailed comparative analysis and, therefore, was used in the preparation of the proposed standard high-resolution karyotypes and idiogram.

A proposed standard high-resolution G-band karyotype of the domestic sheep and goat is presented, along with a high-resolution G-band idiogram of the goat. The karyotypes presented contain considerably more bands than contemporary karyotypes and provide much greater resolution for linear differentiation. The X chromosome of the sheep is acrocentric, rather …

An Otopathological Assessment Of Dogs Exposed To Excessive Dietary Fluoride And/Or Suspected Water Borne Toxins, Barbara Ann Hannah

Masters Theses

In 1970, a once very productive Allegan, Michigan dog kennel began experiencing a rash o£ unexplained perinatal deaths and reproductive anomalies in Shetland pups. Anomalies including cleft palate and lip, kinked tails, twisted feet and convulsions immediately before death plagued the neonates. The adult dogs were reported to have tooth mottling, exostoses and auditory and vestibular problems.

Because the dogs had been on high fluoride diets and because the kennel well water was suspected of harboring toxins, a group of 20 Shetland dogs was used to try to find if there was any correlation between the reproductive problems and the …

The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell

Masters Theses

Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …
