The Effects Of Skeletal Muscle Specific Cpt1b Knock Out On Genetically Obese Ay Mice, Allison Stone

LSU Master's Theses

Fatty acid oxidation inhibition is one approach to reducing blood glucose levels in type II diabetes. Skeletal muscle specific Carnitine Palmitoyltransferase 1b knockout mice (Cpt1b^m-/-) cannot transport long-chain fatty acids into the mitochondria to be oxidized in order to produce energy. Cpt1b^m-/- mice have debilitated fat oxidation, less fat mass and improved glucose utilization compared to control C57BL/6 mice fed a 25% fat diet.

We hypothesized that CPT1b inhibition could reduce fat mass and lower blood glucose levels in a genetic mouse model of obesity and diabetes. To test this, we bred Cpt1b^m-/- mice to A …

Geometric Visual Illusion Effects On Visual Perception And Visuomotor Control: Emphasis On The Vertical-Horizontal Illusion, Shijun Yan

LSU Doctoral Dissertations

The focus of this dissertation was to explore the effects of potential vertical-horizontal (V-H) illusory influences on perceptuomotor control. As part of this focus, we examined the potential use of separate cortical visual streams: the ventral visual stream for perception and the dorsal visual stream for action. Three studies were conducted to determine the effects of the V-H illusion influences on length estimations using upper limb point-to-point movements and lower limb stepping movements, involving various illusory configurations, movement directions, gaze directions. After a short introduction (Chapter 1) and a more detailed review of existing literature (Chapter 2), we present manuscripts …

Characterization Of Drosophila Boundary Element Associated Factor Beaf-32b Interactions With Transcription Factors And Chromatin Remodeling Complexes., Yuankai Dong

LSU Doctoral Dissertations

BEAF (Boundary Element-Associated Factor) was originally identified as a chromatin domain insulator binding protein, suggesting that it might play a role in linking gene regulation to chromatin organization and dynamics. Genome-wide mapping found that BEAF is usually found near transcription start sites, often of housekeeping genes, suggesting that it might play a role in promoter function. This would be a nontraditional role for an insulator binding protein. To gain insight into molecular mechanisms of BEAF function, we identified proteins that interact with BEAF using yeast 2-hybrid assays. Here we focus on three identified transcription factors: Bcd, Scr and Sry-δ. Interactions …

Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, Giovana Matos Franco

LSU Master's Theses

The crapemyrtle bark scale (CMBS), Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an important pest of crapemyrtles, Lagerstromia spp. (Myrtales: Lythraceae) since its damage results in an unpleasant aesthetic. Current CMBS management methods depend heavily on pesticides which impact on beneficial insects. Biopesticides show potential for pest control, host specificity, and low impact towards non-target organisms. The objectives of my thesis were to determine (1) if biopesticides are effective against CMBS infestations when applied in different seasons, and (2) their effects towards coccinellids known to attack CMBS.

To test the efficacy of selected biopesticides, treatments were delivered to potted plants or …

Larval Survival And Movement Of The Fall Armyworm And Corn Earworm (Lepidoptera: Noctuidae) In Seed Blends Of Non-Bt And Pyramided Bt Corn: Implications For Resistance Management, Marcelo Dimase

LSU Master's Theses

A seed blend refuge has been used in the U.S. Corn Belt for Bt corn insect resistance management (IRM). The fall armyworm, Spodoptera frugiperda (F.), and corn earworm, Helicoverpa zea (Boddie) are major target pests of Bt corn in the Americas. One major concern for the use of a seed blend refuge is that larval movement of insects among non-Bt and Bt plants could affect its efficacy for resistance management. To address this concern, field and greenhouse trials were conducted to determine 1) if seed blend refugia could provide comparable levels of susceptible S. frugiperda (aabb) as structured refugia and …

The Effects Of Oral And Venereal Transmission Of Deformed Wing Virus On Honey Bee (Apis Mellifera) Queen And Colony Health, Sarah Lang

LSU Master's Theses

Honey bees are important pollinators necessary for the production of many foods. Managed honey bee colonies have been experiencing high levels of colony loss over the last decade due to a combination of different factors. Parasites, pathogens, and queen failure are repeatedly reported as major causes for colony loss, but there is little research exploring the relationship between honey bee viruses and queens. Deformed wing virus, a major honey bee virus, has a worldwide distribution, is extremely prevalent, and can infect all castes and life stages. Honey bee queens can be infected with the virus through multiple transmission routes …

Applications Of Unmanned Aerial Vehicles For Conducting Mesocarnivore And Breeding Waterfowl Surveys In Southern Manitoba, Jacob Bushaw

LSU Master's Theses

Unmanned aerial vehicles (UAVs) are becoming an increasingly important tool for wildlife surveys and equipping UAVs with thermal imaging cameras could make these surveys even more effective. In my thesis I examined the feasibility of using a UAV equipped with a thermal imaging camera to conduct mesocarnivore surveys, search for duck nests built over water, and conduct duck brood surveys in southern Manitoba.

For my first objective, I conducted nighttime mesocarnivore surveys with the UAV and thermal camera. I used a modified point-count survey from six waypoints and surveyed 29.5 ha in each replicate. I conducted a total of 200 …

Influence Of Health Beneficial Monk Fruit Sweetener On Microbial And Physicochemical Characteristics Of Camel Milk Yogurt, Alina Buchilina

LSU Master's Theses

Camel milk contains all the essential nutrients found in cow’s milk and has potentially health beneficial compounds such as anti-carcinogenic, anti-hypertensive, anti-inflammatory, and insulin and insulin-like substances. Camel milk has been reported as a treatment for diseases such as diabetes and autism. Camel milk favorably alters gut microbiota to a higher abundance of bifidobacteria.

Sweetness is one of the most desirable tastes in people’s diet; however, the surplus consumption of sugar has a negative effect on human health. Monk fruit sweetener is a natural zero caloric sweetener with many health beneficial properties, namely, prevention of asthma, prevention of oxidation, liver …
