1. Twenty-three lines of chickens, obtained from grandparent stocks of 4 Australian breeding companies, were analysed to determine the incidence of early embryonic mortality attributable to chromosome abnormalities. The lines included 10 layer strains, consisting of 6 White Leghorn, 2 New Hampshire and 2 Australorp lines, and 13 broiler lines. 2. A total of(More)
The deceleration phase of the pitching mechanism requires forceful eccentric contraction of the posterior rotator cuff. Because traditional isotonic strengthening may not be specific to this eccentric pattern, a more effective and functional means of strengthening the posterior rotator cuff is needed. Twelve collegiate baseball pitchers performed a moderate(More)
Sixteen haploid-diploid chickens, four diploid-triploids, and one haploid-diploid-triploid chicken have been found in a layer line of crossbred origin. Live haploid-euploid vertebrates have not been reported previously. Flow cytometric analysis revealed 1-80% haploid red blood cells (RBCs) in the haploid-euploid chickens and 5-30% triploid RBCs in the(More)
BACKGROUND The purpose of this study was to determine the effect of moderate physical activity/fitness on the immune response to a defined antigen, in particular, the hemagglutinin-inhibition response to the H1 (A/Texas/36/91) and H3 (A/Johannesburg/33/94) components of the 1995-96 Influenza virus vaccine. METHODS Sixty-seven volunteers 18-30 years of age(More)
Hamman's crunch of pneumomediastinum is an unusual, adventitious sound heard on auscultation of the chest. Its rarity and dramatic nature frequently result in an expensive evaluation and hospitalization. Once recognized, it can be managed on an outpatient basis with serial chest radiographs to resolution of the pneumomediastinum or pneumothorax.
A prospective study of women's flag football injuries was carried out over a 4 year period at Mississippi State University. Data was gathered on 114 injuries. Organized intramural flag football activities caused 93% of the injuries observed (7% were injured in pick-up games). The finger accounted for 39%, knee for 16%, and ankle for 8% of these injuries.(More)
In this case of ophthalmooestriasis externa in a 20-year-old white male student attending Mississippi State University, three first instar larvae from the sheep nasal bot fly, Oestrus ovis, were removed. The patient responded well to application of sulfa eye drops. The exact means by which the patient acquired the larvae was not determined.
Of 72 patients with chronic myelogenous leukemia (CML), 37 were Ph1 positive, eight were negative, and 27 were not evaluated for the Ph1 chromosome. Of the 37 patients positive for Ph1, 31 had adequate evaluation. These 31 patients were reviewed for survival with reference to spleen size. Seventeen patients with spleens 3 cm or less below the left costal(More)
