Potential Mechanisms Linking Nutrition And Neuroendocrine Control Of Reproduction In The Sheep, Adam Bradley Dobbins
Potential Mechanisms Linking Nutrition And Neuroendocrine Control Of Reproduction In The Sheep, Adam Bradley Dobbins
Graduate Theses, Dissertations, and Problem Reports (ETD)
Nutrition and reproduction are linked in that the nutritional status of an individual influences its reproductive performance, i.e. an individual in negative energy balance will have decreased ability to reproduce. The mechanisms in which nutrition influences reproduction are not understood. My data suggest that reductions in lutenizing hormone secretion resulting from photoperiod-induced increases in sensitivity to testosterone negative feedback may be mediated, at least in part, by elevated neuropeptide Y (NPY), a hypothalamic neuropeptide shown to alter gonadotropin releasing hormone release and potently affect food intake. The results from my second study support our hypothesis that the growth hormone mediated …

Pentosidine As A Biomarker For Age In Birds And Museum-Prepared Study Skins, Jesse A. Fallon
Pentosidine As A Biomarker For Age In Birds And Museum-Prepared Study Skins, Jesse A. Fallon
Graduate Theses, Dissertations, and Problem Reports (ETD)
The phenomenon of aging is progressive, irreversible and universal to all living things. One unavoidable outcome of aging is the modification of proteins by sugars, which, through a non-enzymatic process, can lead to the formation of crosslinked compounds termed advanced glycation endproducts. One such endproduct, pentosidine (Ps), is an indicator, or biomarker, of biological age. Because most birds have no reliable markers of age beyond adulthood, this investigation examines the accumulation of Ps as an estimator of chronological age in birds. The first study herein examines interspecies comparison of Ps accumulation in Ruffed grouse and Double-crested cormorants. The second investigates …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Fresh weight, dry weight, and macronutrient content of corollas, ovaries, and styles were measured during the development and senescence of several wild-type and transgenic Petunia x hybrida plants. Flowers of age-related senescence exhibited growth, maintenance, and senescence phases during development. Flowers terminated by pollination-induced senescence exhibited only growth and senescence phases. Fresh and dry weight of Mitchell, V26, and SAG12-IPT corollas followed patterns previously observed in climacteric flowers. SAG12-IPT, a cytokinin overproducing plant, exhibited a prolonged maintenance phase compared to V26. A temporary increase in fresh weight, dry weight, and macronutrients of Mitchell corollas occurred at the expected onset of …
Effect Of Grain Particle Size, Feed Form And Pellet Texture On Broiler Performance, Carcass Quality, True Metabolizable Energy, Feed Passage Time And Preference, Amy S. Parsons
Graduate Theses, Dissertations, and Problem Reports (ETD)
Treatments consisted of five mash diets (781 microns, 950 microns, 1,042 microns, 1,109 microns, 2,242 microns) and two pelleted diets (water (soft) and binder (hard) inclusion). Water and binder addition produced similar pellet durability (90.4% and 86.2% respectively) and fines (44.5% and 40.3% respectively).;Broilers fed mash diets exhibited decreased live weight gain and breast yield with increased gizzard, compared to broilers fed pelleted diets. As diet particle size increased, feed intake and gizzard yield increased and feed efficiency decreased. Broiler true metabolizable energy increased then decreased when diet particle size increased. Hard pellets increased live weight gain. Fines of the …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Context. The obesity epidemic is now threatening youth. Yet little is known regarding the factors associated with adolescent weight status.;Objective. To determine whether dietary intakes, physical activity, and hours spent viewing television are related to the body weight status of West Virginia adolescents.;Design, setting, and participants. This descriptive study included survey, diet recall, and body mass index data from 1,036, 14--20 year olds attending West Virginia high schools during the years 2002 to 2003.;Results. Overweight students consumed less kilocalories (∼378) (P < .001), less servings of total grains (P < .01) and a greater percentage of their energy from protein (P = .01). A significantly less amount of overweight students reported participating in strengthening/toning physical activities on three or more days of the week (P < .01).;Conclusion. Overweight adolescents within the state of West Virginia appear more likely to restrict their energy intake rather than exercise to lose weight. Thus, public health intervention strategies to help these students reach a healthy weight while maintaining adequate nutrition are imperative.

Use Of A Token Economy To Increase Exercise In Children With Cystic Fibrosis, Rebecca S. Bernard
Use Of A Token Economy To Increase Exercise In Children With Cystic Fibrosis, Rebecca S. Bernard
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cystic fibrosis is a chronic illness that affects several major organ systems, primarily the respiratory system and the exocrine glands of the pancreatic system. The treatment regimen is extensive (e.g., medications, vitamins, high fat diet, airway clearance sessions). Although adherence to medications is high, adherence to the airway clearance techniques (chest physiotherapy and exercise) is less consistent. Increasing exercise adherence is of utmost importance because pulmonary difficulties are associated with the highest mortality rate and exercise is more beneficial than other airway clearance methods. Despite this, very little research has focused on increasing exercise adherence in this population. The purpose …
