Assessing and Mediating Pain in Dairy Cows with Experimentally-Induced Clinical Mastitis
… enrolled in a lipopolysaccharide (LPS) endotoxin challenge study, where one mammary quarter was infused with 25 µg of Escherichia coli (E. coli) LPS endotoxin. Subsequently, a subcutaneous injection of either a non-steroidal anti-inflammatory drug (NSAID) (meloxicam; n=12) or placebo (n=12) was …

EXAMINATION OF THE EFFECTIVENESS OF PROVISION OF FUNCTIONAL AMINO ACIDS TO ENHANCE ROBUSTNESS IN ENTERIC CHALLENGED PIGS
… supplementation in Salmonella Typhimurium (ST)-challenged pigs and its interaction with dietary protein content and source, and with pig birth weight. The impact of adaptation period to FAA before a ST challenge was also evaluated. A disease challenge study revealed improved growth performance …

Validation of dog treats and bones for the presence of Salmonella through in-plant analysis and inoculation challenge studies
… various dog treats through an in-plant analysis study and an inoculation challenge study. For the in -plant analysis study, thirty raw and thirty cooked samples of lamb lung cubes, weasands (weasands), pizzles (steer pizzles), and jumbo pizzles were delivered to the Texas Tech University Food …

Female hairdressers - Respiratory symptoms, mechanisms, and health-related quality of life and their views on the work environment
… associated nasal symptoms (S+) responded in a challenge study with increasing symptoms and albumin in nasal lavage at a nasal challenge with persulphate, and atopic females to a lesser intent. The reaction of the S+ did not seem to be IgE-mediated. After a month's work S+ reacted with …

Modified atmosphere packaging of hard grated cheeses
The objective of this study was to use MAP technology to produce safe, shelf-stable, high quality, hard grated cheeses not requiring preservatives or refrigeration during distribution and sale. Initially, a challenge study with Staphylococcus aureus (S. aureus) was conducted to determine the water …

The Effectiveness of Potassium Lactate and Lactic Acid Against Campylobacter Species and Psychrotrophic Bacteria
This study examined the efficacy of potassium lactate and lactic acid to control Campylobacter sp. and psychrotrophic bacteria on chicken. The objectives of the two studies conducted were to determine the optimal combination of potassium lactate and lactic acid to inhibit Campylobacter sp. in a …

Proteomics in Nasal Lavage Fluids from Persulfate Challenged Hairdressers
… in nasal lavage fluids (NLF) from hairdressers challenged with persulfates. Proteins regulate most biological processes in the human body. Changes in protein levels may therefore provide a better understanding of disease pathogenesis and/or candidate biomarkers for persulfate exposure, effect …

Inferring Determinants of Viral Transmission using Short-Read Sequence Data
… selection for an influenza transmission study in pigs, employing my model to deduce a generally narrow transmission bottleneck in these animals. Finally, I consider an influenza human challenge study and compute an effective single-segment within-host selection profile on the basis of an …

Elucidating the Immunogenicity and Protective Immune Response of a Trivalent Vaccine for Sudan Ebola, Marburg, and Lassa Fever Viruses
… measures are limited. Considering the challenges associated with production costs and delivery, particularly to populations with restricted access to healthcare, the development of a multivalent vaccine candidate with the aim of eliciting protection against all three viruses presents a …

Production of plant-expressed virus-like particle vaccines against infectious bronchitis coronavirus and vaccine efficacy in chickens
… economic losses to the poultry industry. In this study, virus-like particles (VLPs) were produced using Agrobacteriummediated transient protein expression in Nicotiana benthamiana plants as potential vaccines against IBV. Modifying the full-length IBV Spike (S) protein resulted in high levels of …

Automated Design of Additive Manufactured Flow Components
… applications. Despite the potential of AM, a key challenge is to design complex parts for AM. In practice, a common approach is to manually create the 3D geometry of parts using computer-aided design (CAD) tools. However, a manual design process can lead to several challenges. First, it requires …

Characterization of virulence-attenuated Listeria monocytogenes common among food and food-associated environments but rarely associated with disease
… and (ii) confer protection against a subsequent challenge by a fully-virulent strain. Results provided evidence that after exposure to L. monocytogenes carrying a VA SNP in inlA, there is an expansion of Listeria-specific CD8+ T effector cells that ultimately lead to a stably maintained pool of …
