The Effect Of Physical Activity On The Insulin Response To Frequent Meals, Michael E. Holmstrup Dec 2011

The Effect Of Physical Activity On The Insulin Response To Frequent Meals, Michael E. Holmstrup

Exercise Science - Dissertations

Long, uninterrupted bouts of sedentary behavior are thought to negatively influence insulin sensitivity, and may impact metabolic function regardless of adherence to general physical activity guidelines. The purpose of this study was to determine the combined effect of physical activity (1 h continuous exercise v. intermittent exercise throughout the day) and meal consumption on glucose excursions, insulin secretion, and appetite markers in obese individuals with prediabetes. Methods: Eleven healthy, obese subjects (>30 kg/m2) with prediabetes underwent 3, 12 h study days including sedentary behavior (SED), exercise (EX; 1h morning exercise, 60-65% VO2 max), and physical activity (PA; 12 hourly, …

The Effects Of Ovariecotomy On Neuropeptide Y Neurotransmission In Skeletal Muscle Arterioles, Kirk Wendell Evanson May 2011

The Effects Of Ovariecotomy On Neuropeptide Y Neurotransmission In Skeletal Muscle Arterioles, Kirk Wendell Evanson

Graduate Theses and Dissertations

The purpose of this study was to determine the effects of chronic estrogen supplementation on NPY neurotransmission in gastrocnemius first-order arterioles (G1A) of adult female rats. Female rats (4 mo; n = 30) were ovariectomized (OVX) with a subset (n = 15) receiving an estrogen pellet (OVE; 17β-estradiol (4μg / day)). Following conclusion of the treatment phase (8 weeks), red G1A were excised, placed in a physiological saline solution (PSS) bath, and cannulated with micropipettes connected to albumin reservoirs. A sampling port was placed immediately below the vessel to assess NPY overflow. The contralateral red G1A was homogenized in PSS …

The Relationship Between 11-Ketotestosterone, Cortisol, And Testosterone And Condition Index For Poecilia Reticulata, Shelly Gupta, Brandy G. Kalbach Mar 2011

The Relationship Between 11-Ketotestosterone, Cortisol, And Testosterone And Condition Index For Poecilia Reticulata, Shelly Gupta, Brandy G. Kalbach

Biological Sciences

The guppy, Poecilia reticulata, is a common study organism for behavioral and other ecological experiments (Houde, 1997).  As far as we know, no previous data have been compiled regarding hormones and condition index of guppies.  In this experiment we examined the relationship between circulating levels of three hormones (testosterone, 11-ketotestosterone and cortisol) and condition index in males and also made comparisons among the hormone levels, for three guppy sites from the northern range of Trinidad – Aripo River, Marianne River and Small Crayfish River.  Hormone samples were obtained using non-invasive water borne techniques and quantified by our collaborator.  The condition …

Reciprocal Regulation Of Trek-1 Channels By Arachidonic Acid And Crh In Mouse Corticotropes, Andy K. Lee, James L. Smart, Marcelo Rubinstein, Malcolm J. Low, Amy Tse Feb 2011

Reciprocal Regulation Of Trek-1 Channels By Arachidonic Acid And Crh In Mouse Corticotropes, Andy K. Lee, James L. Smart, Marcelo Rubinstein, Malcolm J. Low, Amy Tse

Faculty Publications - Department of Biological & Molecular Science

Arachidonic acid (AA) is generated in the anterior pituitary gland upon stimulation by the ACTH secretagogue, CRH. Using the patch clamp technique,we examined the action of AA on the excitability of single pituitary corticotropes obtained from a transgenic mouse strain that expresses the enhanced green fluorescent protein driven by the proopiomelanocortin promoter. CRH evoked depolarization, but AA caused hyperpolarization. Under voltage clamp condition, AA caused a rapid inhibition of the delayed rectifier K current and then increased a background K current. Inhibition of AA metabolism did not prevent the activation of the K current by AA, suggesting a direct action …

Distinct Functions Of The Fshr Ck2 Consensus Sequence And Ck2 Kinase Activity In Fsh Action, Kerri S. Kluetzman Jan 2011

Distinct Functions Of The Fshr Ck2 Consensus Sequence And Ck2 Kinase Activity In Fsh Action, Kerri S. Kluetzman

Legacy Theses & Dissertations (2009 - 2024)

Human reproduction in the female is a complex process requiring coordinated control of gonadotropic hormone signaling in a temporal, spatial and contextually defined manner. Paracrine and autocrine signaling between granulosa cells and oocytes of the developing ovarian follicle result in production of steroids, inhibin and growth factors that dictate maturation, ovulation or atresia. Follicular stimulating hormone (FSH) stimulation of the FSH receptor (FSHR), a G-protein coupled receptor (GPCR) is a key regulator of these processes. Recent developments in GPCR molecular and structural biology have helped define activation and signaling mechanisms that will aid in further defining the etiology of infertility …

Assessment Of Fertility Potential In Bottlenose Dolphins (Tursiops Truncatus): An Elisa-Based Biomarker Analysis, Leslie Schwierzke Wade Jan 2011

Assessment Of Fertility Potential In Bottlenose Dolphins (Tursiops Truncatus): An Elisa-Based Biomarker Analysis, Leslie Schwierzke Wade

USF Tampa Graduate Theses and Dissertations

As apex predators in coastal systems, bottlenose dolphins (Tursiops truncatus) are susceptible to persistent organic pollutant (POP) accumulation and retention over time, which has prompted continued interest in understanding the extent to which contaminant body burdens or other stressors are sufficient to cause adverse sublethal effects on energetic fitness, immune function, or reproduction. Increasing our knowledge of reproductive endocrinology in bottlenose dolphins may provide insight into changes in reproductive rates, thereby expanding the capacity to assess conservation status. This study used the Enzyme-Linked ImmunoSorbent Assay (ELISA) technique to examine peptide fertility hormones [inhibin A, inhibin B and anti-Müllerian …
