Study Of Three Potential Variables That May Impact The Maximum Shear Force And Shear Variation During The Growth And Transport Of Mixed Sex Broilers Grown In Commercial Poultry Houses, 2018 University of Arkansas, Fayetteville
Study Of Three Potential Variables That May Impact The Maximum Shear Force And Shear Variation During The Growth And Transport Of Mixed Sex Broilers Grown In Commercial Poultry Houses, Mark Christie
Theses and Dissertations
Temperature conditions during the transportation to the processing facility of commercial broilers have a direct impact on the meat texture, specifically maximum shear force and shear variation of cooked breast meat. Analysis of a calendar year of flock data (N=346), reveals that the largest impact of transport conditions, specifically temperature, is on the standard deviation of the flocks range of cooked shear values. The optimal transport temperature that yields broiler breast meat with average flock minimum shear and standard deviation values is approximately 60°F. The shear values for flocks at or near 60°F are on average 1 ...
Optimizing Methods To Determine Metabolizable Energy Values Of Feed Ingredients For Broilers, 2018 University of Arkansas, Fayetteville
Optimizing Methods To Determine Metabolizable Energy Values Of Feed Ingredients For Broilers, Skyler P. West
Theses and Dissertations
Determination of metabolizable energy (ME) and amino acid (AA) digestibility values of single feed indigents continues to be two of the most important aspects for successful least-cost poultry feed formulation. It would be advantageous if a common diet type could be utilized to determine both ME and AA digestibility values of feed ingredients within a single assay. Two experiments were conducted to evaluate the effect of basal diet type and excreta collection method on the ME value of single feed ingredients determined in broiler chicks using the regression method. In experiment 1, the objective was to investigate the influence of ...
No Evidence For Kin Protection In The Expression Of Sickness Behaviors In House Mice, 2018 Chapman University
No Evidence For Kin Protection In The Expression Of Sickness Behaviors In House Mice, Patricia C. Lopes, Per Block, Alice Pontiggia, Anna K. Lindholm, Barbara König
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
When infected, animals change their behaviors in several ways, including by decreasing their activity, their food and water intake, and their interest in social interactions. These behavioral alterations are collectively called sickness behaviors and, for several decades, the main hypotheses put forward to explain this phenomenon were that engaging in sickness behaviors facilitated the fever response and improved the likelihood of host survival. However, a new hypothesis was recently proposed suggesting that engaging in sickness behaviors may serve to protect kin. We tested this kin protection hypothesis by combining a field and a laboratory experiment in house mice. In both ...
Development Of A Pd-L1 Pet Imaging Biomarker, 2018 University of Louisville
Development Of A Pd-L1 Pet Imaging Biomarker, Caleb Jack Bridgwater
Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.
The purpose of this study ...

Cannabinoid Transmission In The Basolateral Amygdala Modulates Prefrontal Cortex And Ventral Hippocampal Activity, 2018 The University of Western Ontario
Cannabinoid Transmission In The Basolateral Amygdala Modulates Prefrontal Cortex And Ventral Hippocampal Activity, Brian J. Pereira
Electronic Thesis and Dissertation Repository
The cannabinoid system is important for maintaining neuron-to-neuron communication within the mammalian brain. One of the most commonly used substances to alter the cannabinoid system is cannabis. Individuals who are exposed to cannabis report having dissociable effects; both positive and negative. High amounts of THC have been commonly associated with the negative effects of cannabis, whereas CBD can be used to counter these. Pre-clinical evidence suggests that the combination of the two compounds can produce a therapeutic benefit for individuals who are susceptible to the effects of THC. The present study investigates whether the combination of THC+CBD can prevent ...

Measurement And Protection Of Lung Health In Poultry Farmers Of Southwestern Ontario, 2018 The University of Western Ontario
Measurement And Protection Of Lung Health In Poultry Farmers Of Southwestern Ontario, Rose-Marie Doyon Dolinar
Electronic Thesis and Dissertation Repository
Chronic obstructive lung disease (COPD), develops gradually, and tends to be noticed by farmers only after there has been a significant loss of lung function. People with symptoms of COPD often present for health care in later stages of disease, because they accept cough or breathlessness as “normal”.
Measurement of lung health for those at risk of developing COPD provides an opportunity for early detection of lung disease, and deter the progression toward irreversible damage to the lungs. COPD is, however, under-diagnosed.
The importance of bringing primary care providers and farmers together, and acknowledging the high-risk nature of occupational exposures ...
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, 2018 Purdue University
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low
The Summer Undergraduate Research Fellowship (SURF) Symposium
In patients over the age of 65 especially, bone fractures represent a significant disease burden. Non-invasive drug therapies are not available for bone fractures which represents a problem for this population. Vasoactive intestinal peptide (VIP) and Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP), two neuromodulator peptides in the glucagon superfamily, have demonstrated positive regulation of osteoblast proliferation and activity. Using acidic oligopeptides, we have developed ligands that target to and accumulate at fracture sites. These targeting ligands can be synthesized in sequence with bone anabolic peptides to minimize off target effects and increase potency at the fracture site to create safer and ...

Identifying The 5’End Of The Camta1 Genes In Zebrafish, 2018 Brigham Young University
Identifying The 5’End Of The Camta1 Genes In Zebrafish, Morgan Fronk
Undergraduate Honors Theses
Congenital heart diseases (CHDs) are a significant cause of infant death and are frequently caused by mutations in transcription factors. Camta1 (calmodulin binding transcription activator 1) is a transcription factor that has been proposed as a modulator in embryonic heart development and a possible cause of CHDs. The only other known member of its family in vertebrates is involved in activating a hypertrophy gene program in adult heart failure. Unlike camta2, camta1 is expressed in the embryonic heart during heart looping. However, few studies have been done on camta1. In zebrafish, there are two camta1 ohnologs (homologs created through a ...
Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), 2018 Western Kentucky University
Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), Kathryn C. Laslie
Masters Theses & Specialist Projects
While substrate-borne vibrations are utilized by different reptile species, true conspecific communication via biotremors has not yet been demonstrated in reptiles. This study follows a preliminary report that the veiled chameleon (Chamaeleo calyptratus) could produce biotremors in communicative contexts. I tested chameleon behavioral sensitivity to vibrations by placing them on a dowel attached to a shaker emitting vibrations of 25, 50, 150, 300, and 600 Hz and then measured their changes in velocity before and after the stimulus. I then paired chameleons in various social contexts [anthropogenic disturbance (human disruption of animal); dominance (malemale; female-female C. calyptratus); courtship (male-female C ...

Regulons, which serve as co-regulated gene groups contributing to the transcriptional regulation of microbial genomes, have the potential to aid in understanding of underlying regulatory mechanisms. In this study, we designed a novel computational pipeline, regulon identification based on comparative genomics and transcriptomics analysis (RECTA), for regulon prediction related to the gene regulatory network under certain conditions. To demonstrate the effectiveness of this tool, we implemented RECTA on Lactococcus lactis MG1363 data to elucidate acid-response regulons. A total of 51 regulons were identified, 14 of which have computational-verified significance. Among these 14 regulons, five of them were computationally predicted to ...

Performing systematic reviews (SR) and meta-analyses is an arduous and time-consuming process that involves not only comprehensive literature searching but also record de-duplication, title/abstract and full-text screening, data extraction, quality assessment, statistical analysis, data visualization, report writing, and the creation of a bibliography. In the past several years, several digital tools and software have become available to facilitate different steps of the systematic review process. However, due to the growing number of tools, it can be difficult for systematic reviewers to make fully informed decisions about which tool(s) to use. Here, we (1) compile a comprehensive list of ...
Juvenile Amphibian Response To Oak And Maple Leaf Litter, 2018 University of Connecticut - Storrs
Juvenile Amphibian Response To Oak And Maple Leaf Litter, Benjamin Breslau
Honors Scholar Theses
The composition of tree species within New England forests has changed significantly in recent decades, with an increase in maple (Acer spp.) abundance and a decrease in oak (Quercus spp.) abundance. Changing forest structure results in changing leaf litter composition of the forest floor, which influences the ground-dwelling amphibians that live in the litter. To better understand how changes to forest composition alters amphibian habitat quality, we recorded the growth and survival of 27 juvenile wood frogs (Lithobates sylvaticus or Rana sylvatica) and 27 juvenile American toads (Anaxyrus americanus) in response to leaf litter type. Between early August and late ...
The Effect Of Diet On Craniofacial Growth In Osteogenesis Imperfecta Mouse Model, 2018 University of North Texas Health Science Center at Fort Worth
The Effect Of Diet On Craniofacial Growth In Osteogenesis Imperfecta Mouse Model, Summer H. Ladd
Theses and Dissertations
Osteogenesis imperfecta (OI, or “brittle bone disease”) is a rare disorder that is caused by genetic point mutations (COL1A1/COL1A2) that affect type 1 collagen. In OI type III (severe) patients, limb bones are more susceptible to skeletal fractures and the bones of the craniofacial region are underdeveloped. Some OI type III patients also suffer from dental malocclusions or fractures (dentinogenesis imperfecta, DI). The goals of this project are 1) to describe the facial phenotype in an OI mouse model, to see if this model can be used to test potential behavioral and pharmaceutical interventions; and 2) to determine if ...
