Acute Nitrate Exposure Causes Proteomic Changes Consistent with the Regulation of Reactive Oxygen and Nitrogen Species
… most common ionic form of nitrogen in aquatic ecosystems. Although nitrate is known to affect ecosystems at high levels through eutrophication, hypoxia and loss of biodiversity, it is considered to be physiologically inert to the individual aquatic organism. To test the physiological effects of …

The Effect of Cellular Dehydration on Glucose Regulation in Lean and Obese Females
<p>A chronically elevated vasopressin level has been associated with an impaired glucose regulation system in humans. A recent study in patients with diabetes suggested that low water intake is associated with impaired glucose regulation. The aim of this study was to examine the effect of …

Cold Tolerance, Temperature Mediated Discontinuous Gas Exchange, and Emergence of the Blue Orchard Mason Bee (<i>Osmia lignaria</i>)
… relationship between low temperatures, emergence and supercooling point of <em>Osmia lignaria </em>were the subject of this study. One hundred sixty-eight bees were subjected to 5 pre-wintering temperature treatments (two constant temperature controls - 22<sup>o</sup>C, 14<sup>o</sup>C, one of …

Cold Tolerance, Diapause and Winter Survival of the Brown Marmorated Stink Bug (<i>Halyomorpha halys</i>)
… halys, </em>is native to eastern Asia and is an invasive pest in the United States. Limited research has been done regarding the factors influencing this species’ winter survival within invaded northern regions. Cold tolerance has been previously evaluated in the eastern United States, …

The Elasmobranch-Microbe Relationship: Trimethylamine n-oxide Synthesis, Urea Hydrolysis, and Microbe-Osmolyte Interactions in the Atlantic Stingray, <i>Dasyatis sabina</i>
… of nitrogenous compounds, primarily urea and trimethylamine n¬-oxide (TMAO). Despite the abundance of these plasma osmolytes, it is notable that elasmobranchs appear to lack urease and TMA oxidase (Tmase), enzymes that scavenge urea-nitrogen and synthesize TMAO, respectively. However, …

Cloning of a <i>CHLAMYDOMONAS REINHARDTII</i> Marker into a RNA Interference Construct to Test Whether the Photoreceptor Chlamyrhodopsin Is Involved in Circadian Clock Resetting
… organism to study the circadian clock in plants and animals. Rhodopsins are blue/green-light photoreceptors also found in <i>C. reinhardtii</i>. Chlamyrhodopsin (COP), the most abundant eyespot protein, was reported to have no role in the phototactic and photophobic responses in <i>C. …

Characterization of Andrenocortical Tissue Morphology, Histology, and Steroid Synthesis Among Finetooth (<i>Carcharhinus isodon</i>), Blacktip (<i>Carcharhinus limbatus</i>), Atlantic Sharpnose (<i>Rhizoprionodon terraenovae</i>), and Bonnethead (<i>Sphyrna tiburo</i>) Sharks
… corticosteroids involved in the stress response and hydromineral balance. Previous research characterizing the elasmobranch interrenal suggests that the number of interrenal bodies that produce the single primary corticosteroid, 1a-hydroxycorticosterone (1a-OHB), varies among species. However, …

Regulation of Endothelial Nitric Oxide Synthase in Pulmonary Myofibroblasts
… lung disease leading to decreased lung volume and eventual respiratory failure. At present, the median post-diagnosis lifespan is between three and six years. Myofibroblasts are collagen-secreting cells essential for wound healing, but also implicated in the fibroproliferation and extra …

Effects of Pre-Release Physical Stressors on Post-Release Success of Hatchery-Reared Spotted Seatrout
… of habitat associated with coastal development and increased demand for food and recreation can result in the depletion of fisheries resources such as the Spotted Seatrout (Cynoscion nebulosus), the Gulf of Mexico’s most popular recreational fish. Stock enhancement, or the release of cultured …

Aging and Sympathetic Neurotransmission in Two Strains of Rats that Differ in Longevity and Immune Profiles
… signaling via betaadrenergic receptor (β-AR) and reduced proliferation of lymphocytes are evident with increasing age. Although SNA progressively rises with age, effects of age on sympathetic factors may be different across rat strains. If causal relationships exist between sympathetic …

Adding Upstream Sequence and a Downstream Reporter to the Bile Acid Inducible Promoter of <I>CLOSTRIDIUM scindens</I> VPI 12708
… intestines of animals serve to breakdown fats and fatsoluble vitamins. Most of the bile acids are reabsorbed into the enterohepatic circulation, but approximately five percent of these bile acids pass into the large intestine. These bile acids are swiftly deconjugated by the bacterial …

A PROOF OF CONCEPT FOR DETECTION OF PALATO-LINGUAL CONTACT WITHOUT INTRAORAL ELECTRODES IN A HUMAN PARTICIPANT
<p>The author of this thesis conceived and investigated an unexpected electrical signal that may not be noticed during regular electroglottography (EGG) when electrodes are conventionally placed on the anterior surface of the throat. It appears that there is a measurable electrical signal from the …
