An Investigative Study Toward The Development Of A Crosslinked Porcine Xenograft Meniscus Total Replacement, Patrick Ehren Barton

Theses and Dissertations

Meniscus damage is very common and eventually leads to the deterioration of the entire knee joint. The goal of this study was to provide evidence that supports a proof of concept for a decellularized porcine meniscal xenograft to be used as a treatment method for meniscal injury as a partial or full meniscus transplant. This research adapted an antigen removal protocol for articular cartilage to produce decellularized xenografts in 48% of the time and with no significant difference in DNA content as other current methods. DNA and GAG content, and the compression moduli were significantly lower in the xenograft than …

Application Of Food-Grade Ingredient Treated Nets To Control Tyrophagus Putrescentiae (Schrank) (Sarcoptiformes: Acaridae) Infestations On Dry Cured Hams, Xue Zhang

Theses and Dissertations

Tyrophagus putrescentiae (Schrank) (Sarcoptiformes: Acaridae), also known as the ham mite, may infest dry cured hams during the aging process. The fumigant methyl bromide is currently used to control mite infestations, but eventually will not be available for use since it contributes to the depletion of the ozone layer. The use of ham nets treated with xanthan gum, carrageenan, propylene glycol alginate, propylene glycol (PG), and lard were evaluated for their impact on mite orientation to or oviposition on treated or untreated ham cubes, mite reproduction and population growth over a 10-week period. When nets were infused with gum and …

Introduction Of Iodised Salt Benefits Infants’ Mental Development In A Community-Based Cluster-Randomised Effectiveness Trial In Ethiopia, Karim Bougma, Frances E. Aboud, Tizita M. Lemma, Edward A. Frongillo Jr., Grace S. Marquis

Faculty Publications

The effectiveness of salt iodisation in improving the mental development of young children has not been assessed. We implemented a community-based cluster-randomised effectiveness trial in sixty randomly selected districts in the Amhara region of Ethiopia. We randomly allocated each district to treatment and randomly selected one of its villages. In parallel to national salt iodisation efforts, iodised salt was brought early into the markets of the thirty intervention villages before it became widely available in the thirty control villages 4–6 months later. The primary outcome was children’s mental development scores on the Bayley Scales. This was an intention-to-treat analysis using …

Development Of Herbicide Tolerant Tomato, Gourav Sharma

Theses and Dissertations

Tomato is a major horticulture crop grown across the globe. Unfortunately, its yield is reduced by 25% because of auxin herbicides and glyphosate drift. In this present study, wild germplasm of tomato was screened for herbicide tolerance. From the greenhouse study nine accessions for glyphosate and 2,4-D, eleven accessions for dicamba, five accessions for quinclorac, eight accessions for aminocyclopyrachlor, and two accessions for picloram and aminopyralid were identified to be tolerant. A few accessions were selected from each herbicide tolerant group for field trials at two locations in Mississippi in 2016 and 2017. Results indicated that TOM18 was most tolerant …

An Analysis Of Signaling Processes Leading To A Defense Response In Soybean, Brandon Trey Mcneece

Theses and Dissertations

Plant-parasitic nematodes are the cause of devastating yield loss in vital agricultural crops around the world. Heterodera glycines, also referred to as soybean cyst nematode, is the main pathogen of Glycine max (soybean) causing more loss than all other pathogens of G. max combined. The resultant economic impact due to H. glycines in United States soybean production alone is estimated to account for an annual one-billion-dollar loss. Natural resistant genotypes have been found in trials to combat this pathogen. Of the resistant varieties identified, G. max[Peking/PI 548402] and G. max[PI 88788] are the major sources of resistance. Identification of genes …

A Correlation Study On Soil Selenium Content And Diabetes Mellitus In Contiguous United States, Yang-Chih Tsao

Theses and Dissertations

Selenium, the essential trace element, is well known as its antioxidant function, antiviral properties, and its anti-inflammatory function to human health. The relationships between selenium status and diabetes mellitus have been widely studied, but the consistency of results is lacking. This study used diagnosed diabetes incidence from year 2004 to 2012 and soil selenium content by counties within 48 contiguous states in the U.S. with Generalized Linear Mixed Model- R-Side as the major statistical method to determine whether there is a significant correlation or not. Results showed that the diagnosed diabetes population had been increased from 2004 to 2012 for …

Use Of Software Modeling Tools To Understand Population Health Dynamics: Application To Bovine Respiratory Disease In Us Beef Calves Prior To Weaning, Min Wang

Theses and Dissertations

Bovine respiratory disease (BRD) is a significant health problem for cattle producers in terms of economic cost and animal welfare. In the United States (US), it is one of the leading causes of sickness and death in beef calves prior to weaning. Although much research has been conducted to develop vaccines for prevention and antibiotics for treatment, the morbidity and mortality of BRD in beef calves prior to weaning has not improved over the years. The identification of risk factors associated with BRD is an area of focus which might ultimately allow producers to minimize morbidity and mortality from BRD. …

Controlling Forage Weed Species Detrimental To Livestock Production, David Pierce Russell

Theses and Dissertations

Among the vast diversity of plants in the mid-South to which grazing livestock are exposed, there is a need to address certain species that are potentially harmful to livestock health and production. Field and greenhouse experiments were conducted on endophyte-infected tall fescue [Schedonorus arundinaceus (Schreb.) Dumort = Lolium arundinaceum (Schreb.) Darbysh.], a cool-season perennial forage, and perilla mint, (Perilla frutescens (L.) Britton) an herbaceous annual, to determine management techniques and control measures for healthier pasture and livestock systems. When seedheads reached maturity, spring and autumn glyphosate applications at 1.68 kg ae ha-1, coupled with autumn tillage and summer and winter …

Differences In Survival Of Heat Stress Adapted Cells Of Listeria Monocytogenes Egd (Bug600) In Disinfectants And Essential Oils, Amruta Udaysinh Jadhav

Theses and Dissertations

The objective of this study was to investigate the differences in survival of L. monocytogenes EGD (Bug600) (serotype 1/2a) in various disinfectants and essential oils after sublethal heat stress at 48°C for 60 min. The survival of heat stressed L. monocytogenes cells was decreased in lethal acid (HCl or H3PO4 pH 2.5), lethal oxidative stress (H2O2 1000 ppm) and lethal quaternary ammonium compounds (QAC 2.5-3.5 ppm) compared to non-stressed control cells. By contrast, the survival of heat stressed L. monocytogenes cells was higher in lethal alkali (NaOH or KOH pH 12) than the control cells. Also, the survival of heat …

Does The Hispanic Paradox Extend To Morbidity Changes From 1997-2015?, Randall Brent Lee

Theses and Dissertations

Through the lens of the Hispanic Paradox, this thesis examines healthy and unhealthy life expectancy changes occurring from 1997 to 2015 among Hispanics, non-Hispanic blacks, and non-Hispanic whites in the United States. The goal is to determine how Hispanics –disaggregated by nativity status– fare relative to other racial-ethnic groups in regard to changes in the percentage of total life expectancy that is lived in a healthy state (i.e. compression and expansion of morbidity). Using the Sullivan method, multi-state life tables were created with functional limitation prevalence data from the National Health Interview Survey. Results indicate that most subpopulation groups experienced …

Epidemiology Of Enterohemorrhagic Escherichia Coli: Detection And Ecology In Beef Cattle Systems, Liesel J. Schneider

Theses and Dissertations

Enterohemorrhagic Escherichia coli (EHEC) are important foodborne pathogens with a bovine reservoir. For many years, research and regulations have focused on the EHEC serogroup most commonly associated with severe human illness, EHEC O157. However, six additional EHEC serogroups have been identified as important human foodborne pathogens and have been declared adulterants in raw, non-intact ground beef by the United States Department of Agriculture’s Food Safety Inspection Service. Collectively these seven organisms are referred to as EHEC-7. With the addition of these six pathogens, epidemiological studies are needed to estimate the probability for cattle to carry them and to identify risk …

Experimental Development Of Paleoproxies : Investigation Into Anaerobic Conditions And The Amorphous Calcium Carbonate Precursor For Carbonate Minerals, Brittany M. Garner

Theses and Dissertations

Carbonate geochemistry plays an important role in understanding environmental conditions during the time of precipitation. The studies for this dissertation research were focused on carbonate precipitation and crystallization in different chemical and physical environments. The first project aimed to precipitate aragonite at low oxygen levels to identify a correlation between partitioning of trace elements and anoxic and suboxic conditions. The second study focused on the precipitation of amorphous calcium carbonate in varying magnesium concentrations to determine the identity of crystalline material after transformation of ACC. Lastly, the third project was developed to understand transformation of CaCO3 polymorphs. Specifically, whether or …

Investigating Extra Hepatic Steroid And Eicosanoid Metabolizing Enzymes In Cattle, Megan Pauline Theresa Owen

Theses and Dissertations

Steroid and eicosanoid metabolism occurs in two phases and primarily within hepatic tissues, but localized metabolism has been examined in several extra-hepatic tissues in humans and rodents. Phase I of metabolism is performed by Cytochrome P450s (CYP) that add hydroxyl groups to the carbon ring structure which is further metabolized by phase II UDP-glucuronosyltransferase (UGT). The overall objectives of the following experiments were to: 1) determine the amount of extra-hepatic steroid metabolism within reproductive tissues of cattle across the estrous cycle; 2) determine the amount of extra-hepatic steroid metabolism and an oxylipin profile within reproductive tissues of cattle based on …

Field Methods, Sampling Strategies, Historical Documents, And Data Redundancy: A Study Of Historic Tenant Farmsteads In Leflore County, Mississippi, Jayson Jon Zoino

Theses and Dissertations

Historic tenant farmsteads are often thought to be redundant archaeological resources because of their limited temporal range and function which acts to limit the diversity of their archaeological assemblages. However, work has not been done that confirms this equivalence, and archaeologists often write off tenant farmsteads as being too modern or too disturbed to warrant investigation. This is a problematic approach as tenant farmsteads are quickly eroding from the American landscape and a representative sample of sites need to be investigated and preserved before they’re gone. This thesis tests different sampling strategies and field methods that may allow for the …

Application Of Food Grade Coatings To Prevent Mite Infestations In Dry Cured Ham Processing Facilities, Yan Li Campbell

Theses and Dissertations

The ham mite, Tyrophagus putrescentiae (Schrank) (Sarcoptiformes: Acaridae) is the predominant pest of dry cured hams during aging in the processing facilities. Methyl bromide is currently the only known fumigant that is effective at controlling ham mite infestations in aging houses. However, methyl bromide is being phased out of all industries and will be depleted in the near future. The research objectives were to 1) evaluate dry cured hams that have been treated with previously developed food grade coatings for sensory differences, and 2) to develop and determine the efficacy of ham nets incorporated with food grade coatings on controlling …

Genome Maintenance By Selenoprotein H In The Nucleolus, Li Zhang

Theses and Dissertations

Selenoprotein H (SELENOH) is a nucleolar oxidoreductase with DNA binding properties whose function is not well understood. To determine the functional and physiological roles of SELENOH, a knockout of SELENOH was generated in cell lines using CRISPR/Cas9-mediated genomic deletion and in mice by targeted disruption. Based on the sequenced genome, the results of deduced protein sequences indicated various forms of mutants in the CRISPR/Cas9-mediated knockout, including a frame-shift by aberrant splicing and truncated SELENOH by early termination of the translation process. Loss of SELENOH in HeLa cells induced slow cell proliferation, the formation of giant multinucleated cells, accumulation of unrepaired …

Food accessibility was determined for each Mississippi County, based on data obtained from the Retail Survey regarding common fruits and vegetables in available in food stores. Availability data were correlated with four social-economic/demographic variables: race, median household income, SNAP enrollment, and education. There were negative low magnitude correlations between percentages of Africans American and fresh fruit and vegetables availability, and percentages of SNAP benefits recipients and fresh fruit and vegetables availability. Positive low magnitude correlations were found between income and fresh fruit availability, and education and fruit availability. Lastly, moderate positive correlations were found between education and fruit availability and …

In Vitro And In Vivo Effects Of An Encapsulated Butyric Acid And A Lactic Acid Producing Bacteria Used Alone Or In Combination, Dana Kristen Dittoe

Theses and Dissertations

Lactic acid producing bacteria (LAB) and organic acids have been proposed as effective alternatives to antibiotics, however there is limited literature concerning their combination. Thus, the objective of this thesis was to investigate the effects of LAB, encapsulated butyric acid (EBA), and their combination. Under challenged conditions, the in vitro study demonstrated that both EBA and LAB were capable of reducing pathogen proliferation over time, with greater efficacy at lower initial concentration. However, EBA demonstrated a greater effectiveness on pathogen reduction. Under challenged conditions, the results of the in vivo study indicated that birds fed LAB performed comparatively to that …

Incorporating Fermented By-Products Of Lactobacillus Diolivorans Sp. In Food Grade Coatings Designed For Inhibition Of Tyrophagus Putrescentiae On Dry-Cured Hams, Hector Asis Portillo

Theses and Dissertations

Distillate solutions that were derived from concentrated ferment were incorporated into either a carrageenan (CG) and propylene glycol alginate (PGA) gum blend or into a CG, PGA, and xanthan gum (XG) blend. Distillate treatments were compared against a 10% propylene glycol treatment, a gum only control, and negative control using three hams that were cut into 2.5 cm thick slices and then cut into 2.5×2.5×2.5cm cubes (n=50) that were dipped into solutions prior to conducting mite bioassays. Coated and control ham cubes were inoculated with 20 adult mites from the species T. putrescentiae (Schrank), and incubated for 2 and 3 …

Alternative Post Emergence Nitrogen Management Strategies For Delayed-Flood Rice Production, Richard Edward Turner

Theses and Dissertations

Rice (Oryza sativa L.) that is grown in the U.S. is predominantly grown in the mid-south. Current Mississippi State University recommendations for nitrogen (N) fertilization of rice suggest a single application of 168 kg N ha-1 on soils with CEC ¡Ü 20 and 202 kg N ha-1 on soils with CEC > 20. The primary objective was to identify alternative N management strategies that may potentially be used to reduce costs associated with aerial application of N fertilizer to rice. Research was established at the Delta Research and Extension Center, at Stoneville, MS, on two soil textures during 2015 and 2016. …

The Effect Of Controlling Temperature And Relative Humidity On Tyrophagus Putrescentiae (Schrank) (Sarcoptiformes: Acaridae) Infestations On Dry Cured Hams Treated In Food Grade Ingredient Infused Nets, Jasmine Deneen Hendrix

Theses and Dissertations

Since methyl bromide is an ozone depleting substance, there is a significant need to find effective alternative compounds to control mite infestations on dry cured hams. Therefore, the objective of this study was to determine the most effective relative humidity and/or temperature to minimize mite reproduction and mold growth on dry cured hams in untreated and food grade ingredient infused nets. Mites on ham slices in untreated nets were reduced from the initial inoculum level of 50 mites per ham slice when exposed to 85% RH at 24, 28, and 32°C. Results indicated that hams should be stored at 85% …

Use Of Formative Research To Develop A Healthy Eating Social Marketing Campaign For Low Resource Families In Mississippi, Rahel Mathews

Theses and Dissertations

Mississippi leads the nation in chronic disease, obesity, poverty, and food insecurity. Preventing further growth in disease rates, requires a cultural shift towards a ‘healthy eating’ environment. Healthy patterns of food consumption along with physical activity can prevent and reduce these rates. A state-wide ‘healthy eating’ social marketing campaign could motivate voluntary population behavioral change. Three different methodologies were used to develop a strategy for Mississippi: a systematic review of the literature, a state-wide phone survey (quantitative), and focus groups (qualitative). A systematic review of articles published since January 2007 was conducted, using PRISMA guidelines. Five databases were searched with …

Formulation Of Whey Protein Stabilized Multilayered Microemulsion And Nanoemulsion Systems With Hyperoxidative Curcumin, Soma Mukherjee

Theses and Dissertations

A primary emulsion with whey protein isolate (WPI) and hexanoic acid was prepared, and chitosan (Ch) (0.01%, 0.02%, and 0.03%) was added to evaluate its impact on particle size distribution of the emulsion. NaCl (0, 20, 40, and 80 mM) was added to increase ionic interactions to stabilize the multilayer emulsion. Lecithin (0.5%, 1%, 2%, 3 %, w/v) was mixed with the primary emulsion in order to form a multilayer, and casein hydrolysate (CH) was used to stabilize the tertiary emulsion system without the use of NaCl for 28 d at 4 °C.

Listeria Monocytogenes Response To Sublethal Sodium Hypochlorite Induced Oxidative Stress On Its Biofilm Forming Ability And Antibiotic Resistance, Mohit Bansal

Theses and Dissertations

Listeria monocytogenes response to oxidative stress by sublethal sodium hypochlorite was investigated in this study. Continuous exposure of sublethal chlorine influenced biofilm formation and stress adaptation (homologous and heterologous) in L. monocytogenes. The biofilm forming ability of oxidative stress adapted and control cells were investigated on polystyrene surface at 22°C and 37°C. The oxidative stress adapted cells were found to form less biofilm in the presence of chlorine (p < 0.10) when compared to non-treated control cells at both the temperatures. In addition, the biofilm forming ability of L. monocytogenes was reduced significantly at higher sublethal chlorine concentrations (p < 0.10). In conclusion, oxidative stress adapted L. monocytogenes has developed tolerance to chlorine and some of the antibiotics. However, oxidative stress those cells did demonstrate an antibiofilm effect. This demonstrates that oxidative stress reduces L. monocytogenes biofilm formation but can also increase antibiotic resistance.

Management Practices For Corn Producers Implementing Early Planting As A Production Strategy, Matthew W. Hock

Theses and Dissertations

Producers choosing to implement an early corn planting management strategy often experience several yield limiting biotic and abiotic factors. Field variability, flooding, sub-optimal soil temperatures which leads to poor nutrient uptake, delayed emergence and reduced root growth can limit grain production. Three separate experiments were conducted to address some of the negative effects associated with early corn planting. Experiment 1 evaluated flooding effects on several morpho-physiological traits including root system architecture during early crop development. Hybrids (DKC 6208, Pioneer 1197) were flooded at planting (V0) and growth stages V1, V2, V3 for 0, 6, 12, 24, 48, 96 hours. Plants …
