Factors Affecting Basal And Post-Exercise Prolactin Secretion In Horses, Lisa C. Digiovanni Jan 2013

Factors Affecting Basal And Post-Exercise Prolactin Secretion In Horses, Lisa C. Digiovanni

LSU Master's Theses

There has been thorough documentation to support the role of dopamine in the control of prolactin production and secretion in various mammalian species, including the horse. However, there is evidence that other factors are involved in prolactin secretion. Seven experiments were conducted to assess factors that potentially might affect prolactin secretion in the horse. The first two experiments were conducted (separately) to test whether arginine vasopressin (AVP) or vasoactive intestinal polypeptide (VIP) affected prolactin secretion. In each experiment, AVP or VIP was administered intravenously and blood samples were collected to determine the effect on prolactin secretion. Neither peptide produced any …


Effects Of Assorted Coating Materials And Room Temperature Storage On Internal Quality And Oxidative Stability Of Shell Eggs, Jinjuta Jirawatjunya Jan 2013

Effects Of Assorted Coating Materials And Room Temperature Storage On Internal Quality And Oxidative Stability Of Shell Eggs, Jinjuta Jirawatjunya

LSU Master's Theses

Surface coating is an effective/inexpensive method to preserve internal quality and minimize weight loss of shell eggs during storage without refrigeration. No research has been done to evaluate effects of coating on oxidative stability of cooked eggs. In the first study, soybean oil (SO) as a coating material was evaluated for its effects on internal quality and flavor volatile compounds of eggs throughout 5-weeks of storage at 25¢XC. Haugh unit (HU) and yolk index (YI) values decreased whereas weight loss increased during storage. After 5-weeks, SO-coated eggs had consistently higher HU (67.72 vs. 48.45) and YI (0.29 vs. 0.40) than …


Differential Effect Of 14 Free Fatty Acids In The Expression Of Inflammation Biomarkers On Human Coronary Arterial Cells, Adriana Soto Rodriguez Gil Jan 2013

Differential Effect Of 14 Free Fatty Acids In The Expression Of Inflammation Biomarkers On Human Coronary Arterial Cells, Adriana Soto Rodriguez Gil

LSU Master's Theses

Cardiovascular disease is the leading cause of death in the US, and circulating free fatty acids (FFAs) are known risk factors associated with cardiovascular inflammation. The influence of 14 dietary FFAs (including saturated, mono-, poly-unsaturated and trans), on the expression of inflammatory markers in human coronary arterial smooth muscle (HACSM) and endothelial (HCAEC) cells using a cell culture model was investigated. HACSM and HCAEC cell cultures were incubated with 200 μM of each FFA for 8 or 24 h respectively at 37 °C in a 5% CO2 humidified incubator. Inflammatory biomarkers were assessed by ELISA or Western Blot in the …


Vitrification Of Equine Expanded Blastocysts, Fabian Andres Diaz Jan 2013

Vitrification Of Equine Expanded Blastocysts, Fabian Andres Diaz

LSU Master's Theses

The cryopreservation of equine expanded blastocysts (>300 um) has been largely unsuccessful primarily due to the low permeability to cryoprotectants and the large size of the equine embryo. Mechanical alternatives may provide means to overcome the capsule barrier and the relative large embryo size. In this regard, multiple experiments were performed in this study to evaluate different approaches of capsule puncture and blastocoele fluid extraction with the objective to develop a cryopreservation protocol for Day 8 equine expanded blastocysts. In the first experiment, twenty-four Day 8 expanded blastocysts were exposed to standard equine embryo vitrification solutions following one- or …
