Production And Application Of Antibodies Produced Against The Flagella And Hemolysin Of Vibrio Parahaemolyticus, Shreya Datta
Production And Application Of Antibodies Produced Against The Flagella And Hemolysin Of Vibrio Parahaemolyticus, Shreya Datta
LSU Doctoral Dissertations
Vibrio parahaemolyticus is a marine bacterium which is the leading cause of bacterial gastroenteritis due to consumption of raw or undercooked bivalve molluscan shellfish in United States and is considered an important seafood-borne pathogen throughout the world. The conventional methods for enumerating this bacteria from seafood is laborious and time consuming, hence the objective of our study was to develop antibody based method which would be sensitive, user-friendly and less time consuming to detect and enumerate Vibrio parahaemolyticus from oysters. In order to condense time and material two rapid and specific antibody based test methods were developed. In the first …

Characterization Of The Common Eland (Taurotragus Oryx) Estrous Cycle, Parker M. Pennington
Characterization Of The Common Eland (Taurotragus Oryx) Estrous Cycle, Parker M. Pennington
LSU Master's Theses
Three oryx species and nine of eighteen antelope species across three tribes are considered endangered by the IUCN. Though the common eland (Taurotragus oryx) is not endangered, it lends itself well to the adaption of domestic assisted reproductive techniques due to its large size and calm temperament (Hansen et al., 1985). For these techniques to be used efficiently however, the details of the estrous cycle need to be defined within this and other species. Previously, Nowak (1999) proposed the eland estrous cycle to be ~21 days. In addition to cycle length, specifics of the estrous cycle have yet to be …

A Comparison Of Isotonic And Elastic Resistance Exercise On Trapezius Muscle Balance In Overhead Athletes, Phillip Page
LSU Doctoral Dissertations
The scaption exercise (elevation of the arm in the scapular plane) is often performed in shoulder rehabilitation and preventive exercise programs. Three studies were performed to better understand the activation characteristics of the upper trapezius (UT) and lower trapezius (LT) muscles during scaption. The purpose of these studies was to 1) quantify and compare trapezius muscle activation ratios and onset of activation in normal subjects, 2) compare the findings from normal subjects with overhead athletes, and 3) compare the activation ratios and onset of the trapezius with 2 modes of resistance (elastic and isotonic) in overhead athletes. Methods. Healthy college-aged …
Survivorship, Tunneling And Feeding Behaviors Of Formosan Subterranean Termite (Isoptera: Rhinotermitidae) In Response To Trans-Caryophyllene, Qiaoling Qi
LSU Master's Theses
The Formosan subterranean termite, Coptotermes formosanus Shiraki, an invasive species from southern China, is one of the most destructive wood pests in the United States. Presently, termites are managed through chemical control. However, some synthetic chemicals cause serious environmental problems due to their persistence and toxicity. There is growing interest in using natural compounds with low toxicity to mammals to control termites. Trans-caryophyllene is a component of essential oil found in many flowering plants. It is especially abundant in clove oil. It has also been found to be released from the roots of maize damaged by insects. I investigated caryophyllene …

Biophysical Economic Analysis Of Nutrient And Sediment Management Practices In The Mississippi Alluvial Valley, Augustus Nyako Matekole
LSU Doctoral Dissertations
Conventional drainage systems and poorly drained soils tend to increase row crop agriculture nutrient and sediment effluent loads. Best management practices help reduce row crop production environmental pollution. This dissertation looked at nutrient and tillage management practices that could help farmers address future total maximum daily loads (TMDLs) for the Cabin-Teele sub-watershed, within the lower Mississippi River Basin. The dissertation had two objectives. The first objective was to examine the economic and environmental impact of tillage and nutrient management practices in reducing agricultural pollutants to meet TMDL requirements. Relative cost effectiveness of different tillage and nutrient management practices were analyzed …

An Evaluation Of Endurance And Combined Endurance And Resistance Training On Fitness And C-Reactive Protein, Laura A. Daray
LSU Master's Theses
PURPOSE: This study was designed to determine whether endurance or endurance + resistance training would influence circulating C-reactive protein (CRP) levels and if these changes are related to alterations in aerobic fitness and/or body composition. METHODS: Fifty eight healthy young adults aged 18-24 yrs (78% female) were assigned to one of three groups: 1) endurance training (E) (n=18), 2) endurance + resistance training (ER) (n=11), or 3) active control (AC) (n=29). The E group completed 15 weeks of endurance training for either a half marathon (n=6) or full marathon (n=12). The ER group performed 15 weeks of periodized resistance training …
Development And Application Of An Optimization Model For Elite Level Shot Putting, Michael Young
Development And Application Of An Optimization Model For Elite Level Shot Putting, Michael Young
LSU Doctoral Dissertations
Shot putting is one of the most ancient forms of athletic competition. Considerable research has been performed on the event. Despite this fact, research examining performance in the women’s shot put and using the spin technique is very limited. Also, only one attempt has been made to optimize the movement of elite shot putting and no attempts have been made to use the optimization model as a standard for technical training intervention. A series of three experiments were used to explore the development of an optimization model for shot putting and its application as a basis for technical intervention for …

One of the major concerns of the hot sauce manufacturers is separation of sediments and layering of the sauce. Separation is an undesirable production condition because consumers view this as a defect which consequently increases manufacturing costs. Pectins play an important role in pepper processing since it forms gels and influences the final viscosity of the sauce. Hence, its integrity during processing influences the quality of the final product. Failures in pectin stability can sometimes be related to the presence of enzymes. Understanding how the pectin enzymes function during fermentation of pepper sauce is a necessary step in controlling the …
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
LSU Master's Theses
The application of static stretching (SS) has previously been shown to limit performance in force production, reaction time, balance and vertical jump height. When looking at the effect of SS on jump performance, researchers have previously used changes in jump height, in squat jumps (SQ), countermovement jumps (CMJ) and drop jumping (DJ) from self selected heights. To date no one has looked at the effect of SS across a range of drop heights. 30 subjects (15 male and 15 female) participated in 1 familiarization trial and four performance trials. All subjects undertook two days of stretching (ST) and two days …
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
LSU Master's Theses
Transgene expression in stably transgenic organisms is affected by many factors, including the copy number of the transgene in the genome, and by interactions between the transgene and flanking DNA sequences. Transgene copy number has also been shown to effect genetic stability in transgenic plants. Two commonly used methods for transfecting cells are liposome mediated transfection and electroporation. Little is known about the mean transgene copy number or variability of the copy number with these techniques. Quantitative PCR (Q-PCR) has been shown to be an effective method for determining transgene copy number. The objective of this study was to determine …
A Divided-Attention Timed Stepping Accuracy Task As A Procedural Learning Intervention Improves Balance And Functional Performance In Healthy Older Adults, Susan Joy Leach
LSU Doctoral Dissertations
For both healthy individuals and individuals at high risk of falling, certain environments, such as a dual-task situation, require more resources than others to prevent a loss of balance. Stepping assessment tasks can be used to predict falls, and it has been suggested that impaired voluntary stepping may be a contributing factor to falls (Lord & Fitzpatrick, 2001). In this research, a stepping task was used not as an assessment, but as a therapeutic intervention. The purpose of this research was to determine how training with a task that provides a procedural learning environment can affect balance and functional outcomes. …
Three Essays On Environmental Issues Associated With Broiler Production In Louisiana, Nirmala Adhikari Devkota
Three Essays On Environmental Issues Associated With Broiler Production In Louisiana, Nirmala Adhikari Devkota
LSU Doctoral Dissertations
The increasing trends of integrated and concentrated broiler production results in a serious threat to environment through excessive litter production and lack of its proper disposal. Production concentration in limited area is a major source of surface as well as ground water pollution. Nonpoint source pollution from broiler litter applied on land remains a major concern in Louisiana and elsewhere in Southeastern USA. This study examines alternative approaches to reduce pollution originating from broiler production. First, I evaluate why some producers adopt BMP faster than others and what kind of factors affect the time to adoption decision. The duration model …

Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams
LSU Doctoral Dissertations
Nuclear transfer (NT) results in low success rates and research has reported problems with the welfare of cloned animals produced. Evidence suggests the use of a less differentiated donor cell, such as a stem cell, may lead to an increase in the efficiency of the NT procedure. Stem cell characteristics must be clearly defined in order to isolate, identify and optimally culture potential donor cells. Stem cell characteristics such as self-renewal and differentiation have not been identified in stem cells from porcine adipose tissue, an easily attainable tissue resource. The phenotypic profile of cell surface proteins and chromosomal stability of …

LSU Doctoral Dissertations
This research was conducted with broilers to investigate the interactive effects of P and Ca on P requirement, digestibility, utilization, and phytase efficacy. Each treatment had a minimum of 6 replications. One experiment with 3 trials was conducted to identify the nonphytate P (nPP) requirement of 0 to 14 d old broilers. The nPP levels fed ranged from 0.30 to 0.60% with a Ca:nPP of 2.22:1 or 1.9:1. Requirement estimates for 0 to 14 d ranged from 0.52 to 0.60% nPP. One experiment with 2 trials was conducted to identify the nPP requirement of 14 to 28 d old broilers. …
Effects Of Exercising With A Weighted Vest On The Output Of Lower Limb Joints In Countermovement Jumping, Behdad Tahayori
Effects Of Exercising With A Weighted Vest On The Output Of Lower Limb Joints In Countermovement Jumping, Behdad Tahayori
LSU Master's Theses
The effect of exercising with a weighted vest equal to 15% of body mass on vertical jump height was assessed. It was hypothesized that the defined treatment protocol could enhance jumping performance by increasing hip, knee and ankle joint power. The findings of this study showed that the defined active stretching protocol significantly increases jump height in male participants (0.3364 m compared to0. 3456 m from pre to post exercise respectively) but did not yield a significant increase in females. No significant changes in joint angle, torque, power or velocity were observed between the pre and post exercise jumping. However, …
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
LSU Master's Theses
Considerable research has been conducted comparing the effect of continuous and some form of rotational stocking method on animal and forage performance, but most research utilizes put-and-take stocking rates. The purpose of this research was to determine the effect of 12-paddock rotational stocking method (ROT) or continuous stocking method (CONT) of winter wheat (Triticum aestivum) and annual ryegrass (Lolium multiflorum) pastures on beef heifer and forage performance while maintaining a continuous stocking rate of 3.7 heifers/ha. Two experiments were conducted and analyzed separately due to confounding year and location. Heifer ADG and WG/ha tended to be increased by ROT compared …
