Comparative Studies Of Innate Host Defense Mechanisms Against Virulent And Avirulent Species Of Microsporidia, Amber Lynn Mathews

LSU Master's Theses

Microsporidia are ubiquitous, obligate intracellular eukaryotes that cause chronic diarrhea and disseminated diseases in humans, especially in immunocompromised individuals. Macrophages, cellular components of the innate immune system, are believed to be the source of dissemination of this pathogen throughout the body. Little is known about the innate immune response to microsporidia. Macrophages are a source of interleukin (IL)-12 and IL-23 and play an essential role in the link between innate and adaptive immunity. The focus of this thesis is the investigation of the p38 mitogen-activated protein kinase (MAPK) signaling mechanisms and IL-12 and IL-23 production regulated by Toll-like receptor (TLR) …

Estuarine Phytoplankton Response To Annual And Manipulated River Inputs, Jessica Czubakowski

LSU Master's Theses

River water entering estuaries affects the physical and chemical environment at irregular intervals creating a highly dynamic aquatic habitat. Phytoplankton are important primary producers in estuaries that respond quickly to their changing environment. Since 1991, Breton Sound estuary in southeast Louisiana has been directly influenced by Mississippi River water through the Caernarvon Freshwater Diversion structure. Over a 12 month period, the phytoplankton response was examined, in terms of biomass, abundance, community composition and potential phycotoxin production to seasonal changes in river input into the estuary. Within this 12 month period, a short pulse study was also carried out to examine …

Introgression, Health, And Condition Of Florida, Northern, And Fx Hybrid Largemouth Bass In Louisiana Water Bodies, Melissa Ann Fries

LSU Master's Theses

Since 1982, the Louisiana Department of Wildlife and Fisheries (LDWF) has stocked Florida-strain largemouth bass (FLMB; Micropterus salmoides floridanus) to incorporate Florida alleles into native populations (NLMB; M. s. salmoides) and enhance recreational fishing opportunities. I collected habitat data and largemouth bass samples from 12 LDWF stocked reservoirs and disconnected oxbow lakes to examine the relationships between reservoir characteristics, genetic identity, relative weight (Wr), liver somatic index (LSI), parasite loads, and back-calculated length-at-age. I examined the relationships between water body and genetic identity with Wr, LSI, and back-calculated length-at-age by ANOVA. Parasite loads were analyzed with ordinal regression. Principle component …

Formation Of The Neural Tube Epithelium Basement Membrane During Secondary Neurulation In The Chick Embryo, Leslie Ann Mataya

Honors Program Theses

Neurulation, the formation of the neural tube, is an important process in the development of vertebrates. Because this organ ultimately becomes the central nervous system of the organism, the proper development of a fully-functioning neural tube is paramount to its survival. Neural tube defects, like spina bifida and anencephaly, are among the most common congenital malformations present in live human births. The prevalence of these defects is a definite concern to medicine and human health.

Structure Elucidation Of A Glycosylated Benzyl Ester Of Salicylic Acid From The North American Prairie Plant Oligoneuron Rigidum, Sarah Katherine Miesner

Honors Program Theses

The organic extract from Oligoneuron rigidum displayed anti-microbial activity, indicating a potential future use as a natural food preservative. Three novel compounds were isolated from the active extract. The skeletal structure of the three compounds was determined by spectral methods, and the final structural component that remained to be determined was the locations of the acetate groups. Neutral permethylations were performed on the compounds as the first step in determining the locations of the acetate groups; however, the permethylation technique proved to be ineffective, causing cleavage of the native compounds. The structure elucidation will be complete when a non-degradable method …

Predictors Of Posttraumatic Growth, Shame, And Posttraumatic Stress Symptoms In Survivors Of Intimate Partner Violence: The Roles Of Social Support And Coping, Nancy-Jane Kimberly Doane

Graduate Student Theses, Dissertations, & Professional Papers

Research suggests that college students suffer higher rates of intimate partner violence (IPV) than older adults, with between 30 and 60 percent experiencing one or more violent events by their intimates (O'Hearn & Margolin, 2000). Unfortunately, IPV can result in severe psychological complications, including depression, anxiety, problems with interpersonal relationships, posttraumatic stress disorder (PTSD), and shame (Coker et al., 2002; Coker et al., 2003; Kaura & Lohman, 2007; Taylor, 2003). However, research indicates that certain religious and general coping styles and social support can serve as resilience factors, buffering victims from the negative consequences of IPV (Bosch & Schumm, 2004; …

From Subsistence To Dependence: The Legacy Of Reclamation And Allotment On Quechan Indian Lands, 1700-1940, Ian Michael Smith

Graduate Student Theses, Dissertations, & Professional Papers

The Quechan Indians of southeastern California’s Fort Yuma Indian Reservation have occupied the fertile floodplain near the confluence of the Colorado and Gila rivers for more than 300 years. Since their southward migration to this area sometime in the seventeenth century, tribal members supported themselves through the adoption of a multifaceted subsistence strategy that incorporated cultivated agriculture, the semi-cultivation of wild plants, and the gathering of wild-grown foods. To support their agricultural endeavors, the Quechans relied on the annual flooding of the Colorado River to provide both irrigation water and naturally fertilizing silt to the river-bottom lands on which they …

Expanding The Role Of Criterion A2 In Posttraumatic Stress Disorder, Daniel Evan Dewey

Graduate Student Theses, Dissertations, & Professional Papers

Posttraumatic stress disorder is a psychiatric construct that refers to symptoms that may follow exposure to a traumatic event. The current definition of a traumatic event differentiates between the objective event, criterion A1, and an individual’s subjective response, criterion A2. This study investigated the importance of criterion A2 and other intense negative emotions in the development of PTSD. Self-report measures were used to determine the presence or absence of the event criteria A1 and A2, PTSD symptoms, and intensity of emotion type at the time of an event. Criterion A2 emotions at the time of the event were associated with …

A Chance For Redemption: Revising The "Persecutor Bar" And "Material Support Bar" In The Case Of Child Soldiers, Kathryn White

Vanderbilt Journal of Transnational Law

Armed groups in conflicts around the world frequently exploit child soldiers. Despite the unique experience of child soldiers, who are frequently recruited by means of force and deceit, immigration law as it is currently applied may bar former child soldiers from receiving asylum in the United States. In particular, the prevailing agency interpretation of the "persecutor bar" and the "material support bar" equates child soldiers with adults who have committed serious atrocities. This Note argues that the application of these asylum bars to former child soldiers runs against social values and standards of moral culpability in the United States. Child …
