Investigation Of Cnt-Induced Escherichia Coli Lysis And Protein Release, Abdollah Mosleh
Investigation Of Cnt-Induced Escherichia Coli Lysis And Protein Release, Abdollah Mosleh
Graduate Theses and Dissertations
This research investigated the use of carbon nanotubes (CNTs) as a treatment to increase the permeability of a bacterial cell wall. Recombinant Escherichia coli BL21 (DE3) containing a plasmid that expressed Green Fluorescent Protein (GFP) and -lactamase were exposed to CNTs under various levels of agitation for different times. Fluorescence assay for GFP, optical absorbance for -lactamase activity, and Transmission Electron Microscopy (TEM) were used to determine the amount of released protein, and visually examine the permeability enhancement of the cells, respectively. It was found that more -lactamase was present in the culture fluid after treatment with CNTs in a …
Identification Of Biomarkers Associated With Rous Sarcoma Virus-Induced Tumors In Two Divergently Selected Chicken Lines, Ashley Hayden
Identification Of Biomarkers Associated With Rous Sarcoma Virus-Induced Tumors In Two Divergently Selected Chicken Lines, Ashley Hayden
Graduate Theses and Dissertations
Poultry has become especially important to genetic research due to breeding feasibility, short generation turnover, and ease of maintaining large populations. The discovery of virus induced cancer has paved the way for further genetic studies. Rous Sarcoma Virus (RSV) is a tumor-causing virus that infects poultry. While not prevalent today, it can serve as a model for virus-induced cancer in humans and create additional insight to marker assisted selection in poultry. Genetically selected Arkansas Progressor (AP) and Arkansas Regressor (AR) chicken lines have been established and maintained at the Arkansas Experimental Station (AES) in Fayetteville, AR. Previous research has investigated …
Comparisons Of Selected Household And Commercial Disinfectants Against Poultry Salmonella Isolates And A Survey Of Internal Parasites In Backyard Poultry In Arkansas, Kayleigh Moyle
Graduate Theses and Dissertations
Backyard and exhibition poultry have been gaining in popularity and as such there has been a large increase in the number of small flocks. As the interaction with poultry has increased, so has the opportunity for diseases and parasites, for both birds and people. One of the major zoonotic illnesses is caused by the bacteria Salmonella, which can be found in commercial and small flocks. Salmonella is the number 2 contributor of foodborne illnesses so its prevalence in commercial flocks is of high concern. Despite improved cleaning, disinfection, and biosecurity practices, there is still potential for disease outbreaks and infections …
A Molecular Approach To Understanding The Effects Of Original-Xpc On The Modulation Of The Cecal Microbiota And The Survival Of Salmonella In The Poultry Host, Stephanie Roto
Graduate Theses and Dissertations
Salmonella is a foodborne pathogen commonly associated with poultry products; the economic burden to the U.S. is estimated to be approximately $693 million (without factoring in contaminated eggs). Recently, there has been pressure to withdraw sub-therapeutic levels of antibiotics (also known as antibiotic growth promoters; AGP) from poultry due to concern over antibiotic-resistant bacteria spreading to the human population. Therefore, various feed additives have been researched for their ability in providing protection against harmful pathogens and their potential growth promoting effects, both of which were attributes of poultry treated with AGP. This thesis consists of a comprehensive literature review that …
Effect Of Passive Heating On Males And Females With Elevated Arterial Stiffness, Forrest Blake Robinson
Effect Of Passive Heating On Males And Females With Elevated Arterial Stiffness, Forrest Blake Robinson
Graduate Theses and Dissertations
Context: Cardiovascular disease (CVD) is one of the leading causes of mortality in the United States, accounting for about 1 in every 4 deaths annually. Studies have shown that passive heating does have some degree of effect on arterial stiffness, but not much is known about populations with higher stiffness. Objective: To examine the independent effect of core temperature increase during passive heating on arterial stiffness. Methods: Participants visited the lab three times; one familiarization and two experimental trials. The experimental trials consisted of subjects being passively heated in an environment of 40°C / 40% relative humidity (HEAT) or normal …
Efficacy Of A Novel Intranasal Zinc Solution On The Microbiome, Health, And Growth Performance Of High-Risk, Newly Received Stocker Cattle, Makenzie Foster
Efficacy Of A Novel Intranasal Zinc Solution On The Microbiome, Health, And Growth Performance Of High-Risk, Newly Received Stocker Cattle, Makenzie Foster
Graduate Theses and Dissertations
The objective of this study was to determine if using an intranasal zinc (Zn) solution would impact health and growth performance of high-risk stocker cattle. Male beef calves (n = 239; 3 arrival dates [block]; initial BW = 276 ± 2.4 kg) were stratified by arrival gender and BW and assigned to 1 of 2 treatments: 1) treated with 3 ml of a Zn solution containing 36.24 mg of Zn administered intranasally, or 2) control, in which calves were not treated. Calves were observed daily and if exhibiting signs of morbidity and a rectal temperature ≥ 40° C they were …
