Effect Of Concentrations Of Progesterone On Follicular Development And Fertility In Beef Cows, Jason Brian Candler Aug 2001

Effect Of Concentrations Of Progesterone On Follicular Development And Fertility In Beef Cows, Jason Brian Candler

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present study was performed to investigate the effects of low ascending concentrations of progesterone on fertility in lactating beef cattle. Cows on the low ascending progesterone treatment received PGF2alpha from days 3 to 4 after estrus. All cows received PGF2alpha on day 9, and estradiol benzoate on day 11. Cows were inseminated artificially 12 hours after estrus. Concentrations of progesterone were lower in treated versus control cows. Pregnancy rate did not differ between treated and control cows. Pregnancy rate was greater in cows that ovulated a follicle from the right (78%) versus left (52%) ovary (p < 0.01). Low ascending progesterone early in the estrous cycle did not decrease fertility to the same extent seen with extended periods of low progesterone.

Damage Mechanics Of Human Cortical Bone, Gagik Parsam Parsamian Aug 2001

Damage Mechanics Of Human Cortical Bone, Gagik Parsam Parsamian

Graduate Theses, Dissertations, and Problem Reports (ETD)

Skeletal fragility is an important orthopedic concern including the prevention of osteoporosis, long-term stability of prosthetic implants and stress fractures. Damage in human cortical bone has been implicated as a cause of increased fragility and is thought to initiate bone remodeling. Therefore, characterization of the mechanisms of damage initiation and accumulation in bone is challenging not only from the engineering prospective but also has a potential of revealing new insights in its physiology. The main objectives of this dissertation work were to study the early stages of damage development in human cortical bone and develop a constitutive formulation describing damage …

Seasonal Plasticity Of A15 Dopaminergic Neurons In The Ewe, Van Lee Adams Aug 2001

Seasonal Plasticity Of A15 Dopaminergic Neurons In The Ewe, Van Lee Adams

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the ewe, anestrus is caused by increased sensitivity to E2 negative feedback that is mediated by A15 dopaminergic neurons that are only responsive to E2 in anestrus. Experiment 1, tested the hypothesis that synaptic input on A15 neurons varies with season by examining synapsin-positive close contacts on A15 cells using immunofluorescence and confocal microscopy. The number of contacts on dendrites, but not somata, increased during anestrus. There were also corresponding changes in dendritic morphology including an increase in dendritic length, surface area, and number of bifurcations. Because thyroid hormones are necessary for the transition to anestrus, we next examined …

Functional Profiles Of Growth-Related Genes During Embryogenesis And Postnatal Development Of Chicken And Mouse Skeletal Muscle, Hakan Kocamis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reverse-transcription polymerase chain reaction (RT-PCR) was performed to measure myostatin, follistatin, activin-B gene expressions during chicken embryonic development. Strong myostatin expression was found in the early chicken embryos (E 0, E 1) and the developmental expression pattern of myostatin mRNA coincided with the periods of primary and secondary muscle fiber formation. Follistatin transcripts followed a linear expression pattern from E 0 to E 20, while activin-B had a quadratic pattern. The ontogeny of myostatin gene expression was nearly identical in satellite cells isolated from pectoralis major (PM) and biceps femoris (BF) muscles of chicken. Activin-B mRNA level in PM satellite …

Induction Of Fertile Estrus During Seasonal Anestrus In Ewes And Fall Born Ewe Lambs, Marlon Knights May 2001

Induction Of Fertile Estrus During Seasonal Anestrus In Ewes And Fall Born Ewe Lambs, Marlon Knights

Graduate Theses, Dissertations, and Problem Reports (ETD)

The quantity of progesterone (P4) delivered by a new P 4 releasing intravaginal insert (polycapralactone [PCL] insert), was inadequate to increase serum concentrations of P4 to that observed in cycling ewes during the luteal phase. Percentage of ewes in estrus was greater in P4 treated than in control ewes. Estrous response was greater after treatment with P4 for 5 than for 12 d. Progesterone increased the percentage of ewes lambing to both service periods by 20 percentage points. Prolificacy to the first service period in ewes treated with FSH was greater than the prolificacy in control and all ewes lambing …

Attention Deficit Hyperactivity Disorder: Families Choosing Alternate Management Approaches., Christina Mary Lavorata

Graduate Theses, Dissertations, and Problem Reports (ETD)

Attention Deficit Hyperactivity Disorder affects approximately two million American school children by making them distractible and impulsive, and by causing them to have a short attention span in both scholastic and social situations. These characteristics generally result in the students receiving poor marks in academic subjects, being reprimanded frequently, and being labeled as disruptive and difficult to control by both their parents and teachers. Pediatricians and psychiatrists most often prescribe psychostimulant medications to control the syndrome, and this is an effective treatment in sixty to seventy percent of cases. There are questions about the safety of long-term use of medication, …

Testing The River Continuum Concept: Exploring Ecological Processes In The Wheeling Creek Watershed., Deborah Ann Carpenter Jan 2001

Testing The River Continuum Concept: Exploring Ecological Processes In The Wheeling Creek Watershed., Deborah Ann Carpenter

Graduate Theses, Dissertations, and Problem Reports (ETD)

The river continuum concept (RCC) asserts that the biological community in a stream system is largely regulated by geomorphological factors (Vannote, et al., 1980, 131). The concept states that community structure in natural stream systems is structured in order to capitalize on the most efficient energy utilization throughout. The objective of this research is to test the RCC in the Wheeling Creek watershed of northern West Virginia and southwestern Pennsylvania and to compare the results with those hypothesized under the RCC. One of the strongest criticisms of the RCC is that the continuum assumes an undisturbed stream system. Anomalies found …

Effects Of A High Salt Diet On The Microcirculation In Normotensive Rats: The Role Of Reactive Oxygen Species., Deborah M. Lenda Jan 2001

Effects Of A High Salt Diet On The Microcirculation In Normotensive Rats: The Role Of Reactive Oxygen Species., Deborah M. Lenda

Graduate Theses, Dissertations, and Problem Reports (ETD)

In normotensive rats fed high salt, arteriolar responsiveness to endothelium-dependent dilators is reduced due to suppression of local nitric oxide (NO) bioavailability. In the first study we evaluated the possibility that an increase in microvascular reactive oxygen species (ROS) may account for this decrease in NO activity. Arcade arterioles in the spinotrapezius muscle of Sprague-Dawley rats fed either a low (0.45%, LS) or high (7%, HS) salt diet for 4–5 weeks were examined. Arteriolar responses to acetylcholine (ACh) were significantly reduced in the HS rats but could be returned to normal in the presence of the ROS scavengers superoxide dismutase …

The Role Of Accessory Proteins In Controlling The Thyroid Hormone Regulation Of Transcription Of The Malic Enzyme Gene., Yutong Wang Jan 2001

The Role Of Accessory Proteins In Controlling The Thyroid Hormone Regulation Of Transcription Of The Malic Enzyme Gene., Yutong Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Triiodothyronine (T3) stimulates a 70-fold or greater increase in transcription of the malic enzyme gene in chick embryo hepatocytes. Previous work has shown that the effects of T3 on malic enzyme transcription are mediated in large part by sequence elements located within a liver-specific and T3-inducible DNase I hypersensitive region in the 5′-flanking DNA of the malic enzyme gene. Within this DNase I hypersensitive region is a cluster of nuclear T3 receptor (TR) binding sites that together constitute a T3 response unit (TAU). Flanking the T3RU are accessory elements that enhance T3 regulation conferred by the T3RU in chick embryo …

Diversity Of Ectomycorrhizal Fungi On Two Reclaimed Surface Mines Differing In Soil Properties, Betsy S. Kurnik Dec 2000

Diversity Of Ectomycorrhizal Fungi On Two Reclaimed Surface Mines Differing In Soil Properties, Betsy S. Kurnik

Graduate Theses, Dissertations, and Problem Reports (ETD)

I analyzed community structure of ectomycorrhizal fungi on white pine (Pinus strobus) on two reclaimed surface mines in eastern Ohio. One site was acidic and metal-stressed, the other was alkaline. Completely different community composition was found on the two sites by PCR/ITS/RFLP analyses of field collected mycorrhizae. However, Shannon-Wiener index values indicated that the two communities were equally diverse. A population of isolates of one species common to both sites was obtained from trap cultures planted with white pine. The identity of this species as Wilcoxina mikolae was established through DNA sequencing of the ITS region. The W. mikolae populations …

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell Dec 2000

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diabetes is a serious disease that effects a large number of West Virginia's population. A study was conducted using 591 diabetic and non-diabetic subjects who attended the "Dining with Diabetes" program. Subjects completed a demographic form, pretest, and posttest. Pearson's correlation and ANOVA were used to determine the effect of a diabetes intervention program on nutrition knowledge, diabetes behaviors, and practices. The results indicated that there was no significant difference in nutrition knowledge between diabetic and non-diabetic subjects. Interaction was noted when subjects were placed into groups based on their pretest score (p < 0.07). The change in score (posttest score-pretest score) was negatively correlated with pretest score (r = -0.75, p < 0.00). Significant association was also noted between nutrition knowledge score and several behavior and diabetic practices. The results conclude that diabetes education programs may significantly affect some behaviors and diabetic practices.

Evaluation Of Survival And Recovery Characteristics Of Bifidobacteria As Indicators Of Fecal Pollution Of Water, John Elmer Ravenscroft Jr. Dec 2000

Evaluation Of Survival And Recovery Characteristics Of Bifidobacteria As Indicators Of Fecal Pollution Of Water, John Elmer Ravenscroft Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The examination of aquatic environments for bacterial indicator organisms has proven to be a useful and well-established practice for the purpose of monitoring microbiological water quality. An ideal indicator of fecal pollution should be present in sufficient density to allow detection, present simultaneous with pathogen(s), incapable of aftergrowth in external aquatic environments, easy to enumerate, and exclusively of fecal origin. Unfortunately, none of the indicator organisms presently in use today meet all of these requirements. Bifidobacteria show promise as indicators of fecal pollution in water with the additional ability of potentially distinguishing between fecal pollution of human and animal origin. …

Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland Dec 2000

Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many women do not initiate breastfeeding although breastfeeding promotes their baby's health. Three reasons why women do not breastfeed are women's mental organization, cultural beliefs about breastfeeding, and women's breastfeeding personal efficacy beliefs. The conceptual framework for personal efficacy beliefs is Bandura's social-cognitive theory (1992, 1995, 1997). This dissertation used a new research instrument to examine women university students' breastfeeding personal efficacy beliefs. The instrument was tested by mail survey techniques that resulted in a 70.6% respondent rate. University women's personal efficacy beliefs about breastfeeding factored into five factor subscales. In order of magnitude, the personal efficacy belief factors were …

Evidence For A Systemic Embryotoxic Effect Of Early Luteal Regression In The Ewe, Beth Alyson Costine Dec 2000

Evidence For A Systemic Embryotoxic Effect Of Early Luteal Regression In The Ewe, Beth Alyson Costine

Graduate Theses, Dissertations, and Problem Reports (ETD)

Experiments were performed to determine if a short-lived corpus luteum was embryotoxic in ewes given supplemental progesterone and the route of transfer of embryotoxic products. Mated ewes were lutectomized or sham lutectomized on day 4 after estrus. Following surgery, ewes received saline or PGF 2alpha through days 6 or 7. Pregnancy rate was reduced after treatment with PGF2alpha (P < 0.001) compared to controls and was increased in PGF2alpha-treated ewes by lutectomy (P < 0.05). Mated ewes with bilateral ovulations were unilaterally lutectomized, and each uterine horn was ligated to eliminate intercornual flow on day 4 after estrus. Treatment with PGF2alpha on day 5 through 8 reduced pregnancy rates (P < 0.01), but embryonic survival did not differ in the uterine horns ipsilateral or contralateral to the regressing CL. The regressing CL is embryotoxic in progesterone-supplemented ewes, and embryotoxic luteal products have been shown to act by non-local pathways.

Adapting Parent -Child Interaction Therapy To Train Head Start Teachers In Behavior Management, Alisa B. Bahl Aug 2000

Adapting Parent -Child Interaction Therapy To Train Head Start Teachers In Behavior Management, Alisa B. Bahl

Graduate Theses, Dissertations, and Problem Reports (ETD)

Efforts toward greater inclusion of children with a range of presenting problems have resulted in increasingly more children with difficult behavior in non-specialized classrooms. Unfortunately, teachers report that they have not been trained adequately to work with children who exhibit extreme behaviors. It is important, therefore, that effective methods of training teachers are empirically investigated. In clinical settings, strategies for training parents of young children with disruptive behavior disorders have substantial empirical support. Therefore, using these techniques to train teachers is a logical step. Parent-Child Interaction Therapy is one empirically validated parent training approach that uses coaching as a means …
