Fitness: Philosophical Problems, Grant Ramsey, Charles H. Pence
Fitness: Philosophical Problems, Grant Ramsey, Charles H. Pence
Faculty Publications
Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the subject of an extensive philosophical literature, which has primarily centred on the way to understand the relationship between fitness values and reproductive outcomes. If fitness is a probabilistic or statistical quantity, how is it to be defined in general theoretical contexts? How can it be measured? Can a single conceptual model for fitness be offered that applies to all biological cases, or must fitness measures be case-specific? Philosophers have …

Changes In Plasma Melanocyte Stimulating Hormone, Acth, Prolactin, Gh, Lh, Fsh, And Thyroid Stimulating Hormone In Response To Injection Of Sulpiride, Thyrotropin Releasing Hormone, Or Vehicle In Insulin Sensitive And Insensitive Mares, Nicole Arana Valencia
LSU Master's Theses
Six insulin sensitive and six insensitive mares were used in a replicated 3 x 3 Latin square design to determine the pituitary hormonal responses (compared to vehicle) to sulpiride and thyrotropin-releasing hormone (TRH), two compounds commonly used to diagnose pituitary pars intermedia dysfunction (PPID) in horses. Mares were classified as insulin sensitive or insensitive by their previous glucose responses to direct injection of human recombinant insulin. Treatment days were February 25 and March 10 and 24, 2012. Treatments were sulpiride (racemic mixture, 0.01 mg/kg BW), TRH (0.002 mg/kg BW), and vehicle (saline, 0.01 mL/kg BW) administered intravenously. Blood samples were …
Insulin Secretagogue Activity Of Ellagic Acid-Rich Muscadine (Vitis Rotundifolia) And Indian Gooseberry (Emblica Officinalis) Extracts On Pancreatic Beta Cells, Srikanth Earpina
Insulin Secretagogue Activity Of Ellagic Acid-Rich Muscadine (Vitis Rotundifolia) And Indian Gooseberry (Emblica Officinalis) Extracts On Pancreatic Beta Cells, Srikanth Earpina
LSU Master's Theses
Diabetes is an inflammatory disease associated with hyperglycemia. Chronic exposure of pancreatic â-cells to glucolipotoxicity stimulates a low-grade inflammation associated with the release of pro-inflammatory cytokines such as interleukin-1â (IL-1â). Increased levels of IL-1â can initially lead to decreased insulin secretion and finally â-cell death. Ellagic acid and quercetin have been reported to be anti-inflammatory in several studies. Vitis rotundifolia (muscadine) or Emblica officinalis (amla) are good sources of ellagic acid and quercetin. Ellagic acid or quercetin is bioavailable as is or are metabolized into bioavailable urolithins or isorhamnetin, respectively. The objective of this study was to evaluate the effect …
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
LSU Master's Theses
The Louisiana broiler production region is located in North Central and Northwestern Louisiana. The region consists of twelve parishes in Northwestern and North Central Louisiana. The broiler production region is a significant contributor of nonpoint source (NPS) pollution to nearby waterways. This pollution is a consequence of sediment, nitrogen and phosphorus runoff caused by agricultural production. NPS pollution is difficult to mitigate due to uncertainties in its point of origin as well as a host of other factors ranging from rainfall to topographical parameters. Best Management Practices (BMPS) have been shown to be a reliable method for reducing nonpoint source …
Potential Roles Of Wrky Transcription Factors In Resistance To Aspergillus Flavus Colonization Of Immature Maize Kernels, Jake Clayton Fountain
Potential Roles Of Wrky Transcription Factors In Resistance To Aspergillus Flavus Colonization Of Immature Maize Kernels, Jake Clayton Fountain
LSU Master's Theses
The infection and colonization of maize (Zea mays L.) by the necrotrophic fungal pathogen Aspergillus flavus results in contamination of kernel tissues with carcinogenic mycotoxins known as aflatoxins, resulting in severe economic losses as well as negative effects on human and animal health. Resistance to A. flavus is mediated by both inducible and constitutively expressed defense proteins; however the mechanism regulating the expression of these defenses is poorly understood. This study examined the potential roles of six maize WRKY transcription factors, ZmWRKY19, ZmWRKY21, ZmWRKY53, ZmWRKY53.1, ZmWRKY67, and ZmWRKY68, in regulating defense responses against …

The Development Of Gluten-Free Milk-Free French Bread, Annette Camnetar Bentley
LSU Master's Theses
Approximately 6% of children and approximately 4% of adults in the western countries including the United States (US) have food allergies. Milk allergy is reported to be one of the most common food allergies affecting as high as 7% in the US. Celiac disease affects approximately 1% of the US population. Such individuals are required to maintain diets restricting milk and gluten. Autism is estimated to affect over 673,000 in the US. A milk-free gluten-free diet is recommended for autism. The gluten grains identified are wheat, oats, barley and rye and any by-products or cross-bred grains of these products. Foods …
Treatments To Reduce The Risk Of Vibrio Species In Vitro And In Shucked Oysters, Ronson Renard Scott
Treatments To Reduce The Risk Of Vibrio Species In Vitro And In Shucked Oysters, Ronson Renard Scott
LSU Master's Theses
"Vibrio parahaemolyticus" (Vp) and "Vibrio vulnificus" (Vv) are halophilic bacteria naturally occurring in estuarine environments that may concentrate in filter feeding shellfish. Consumption of raw or under-cooked seafood contaminated with Vp or Vv may lead to the development of acute gastroenteritis or fatal septicemia in at-risk individuals, respectively. This research encompassed two separate but related projects: evaluation of a low temperature pasteurization (LTP) technique for the reduction of Vp and Vv in commercial quantities of shucked oysters (SO) and the investigation of the efficacy of a citrus fruit extract, BIOSECUR® F440D in reducing/eliminating Vv in vitro. Commercially available SO ("Crassostrea …
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
LSU Master's Theses
Consumers are becoming conscious of their diet, increasing protein intake and avoiding carbohydrates and fats. Whey proteins have branch chain amino acids responsible for muscle building. Whey protein isolate (WPI) contains more than 90% protein. The effect of incremental addition of WPI on probiotic characteristics of pure cultures and cultures in yogurt and yogurt characteristics are not known. The hypothesis was that “added” WPI will influence the characteristics of yogurt culture bacteria in pure form and in yogurt. The objectives were: to determine the influence of added WPI on (1) acid and bile tolerance, growth and protease activity of pure …
Effects Of Meal Timing On Growth Hormones, Ghrelin, And Insulin Sensitivity In Male Holstein Calves, Erica Lynn Chartier
Effects Of Meal Timing On Growth Hormones, Ghrelin, And Insulin Sensitivity In Male Holstein Calves, Erica Lynn Chartier
LSU Master's Theses
Eighteen neonatal Holstein bull calves (38.85 ± 4.71 kg) were assigned to one of two treatments at birth to determine the effect of feeding time on growth, nutrient intake, metabolic hormone secretion, and energy metabolism. Regularly fed calves (n = 9) were fed MR daily at 0630 h, and irregularly fed calves (n = 9) at 1030, 0800, 0630, 0830, 0530, 0930, and 0730 Monday through Sunday. Body weights were measured weekly from birth to 9 weeks. Water intake, fecal scores, and starter intake were measured daily. Serial blood collections were conducted at 2, 4, 6, and 8 weeks for …
Determination Of Cane Berry Pomaces Benefits Through In Vitro Model For Human Colonic Fermentation, M'Famara Goita
Determination Of Cane Berry Pomaces Benefits Through In Vitro Model For Human Colonic Fermentation, M'Famara Goita
LSU Master's Theses
Cane berry pomaces have traditionally been considered waste products with little or no value. Yet these pomaces’ high levels of phenolic compounds such as anthocyanins, is a good source of dietary fiber. Because the pomaces are low in sugar and rich in fiber and dietary antioxidants, they have potential as food ingredients for the health food market. The pomace delivers health benefits associated with high fiber and the antioxidant polyphenolic compounds associated with whole fruits and juices without the high sugar content. Some dietary fibers are substrates for anaerobic fermentation by the microbiome in the lower gastrointestinal (GI) tract. The …
Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
LSU Master's Theses
Weaning, one of the first major stressors encountered by the calf, has a negative effect on the immune system and increases the likelihood of infection of novel pathogens such as those that cause bovine respiratory disease. Fenceline contact at weaning has been shown to reduce the stress on the calf during the time following maternal separation. Preconditioning programs have been shown to reduce feedlot morbidity and mortality. Combining these two management practices could reduce the length of time calves need to be held in a preconditioning program. A multi-year study was conducted to evaluate if fenceline weaning will allow for …
Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante
Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante
LSU Master's Theses
Reducing added salt in processed foods is one of the major challenges facing food industry worldwide. Salt (NaCl) replacement in a Cheddar cheese has been successfully achieved up to 25%, which qualifies it as “reduced sodium”. However, a low sodium cheddar cheese (less than 140 mg Na/ 50 g cheese) requires at least 50% of salt reduction. Bitterness is one obstacle for development of an acceptable low sodium cheddar cheese. In this study, sensory optimization of low sodium white cheddar cheese was performed. A 3-component mixture design was used: NaCl (30-60%), KCl (45-65%) and glycine (5-10%). A fixed level of …
