Effect Of Floor Cooling On Sows Under Heat Stress, Javier Flores

American Journal of Rising Scholar Activities

With temperatures increasing steadily throughout the last century, the hog farrowing industry is beginning to confront an ongoing dilemma. Temperatures are now exceeding ideal conditions for optimal milk production, as well as maximum litter size. Temperatures that exceed optimal conditions can lead to significant heat stress among sows. Efficiently cooling-down sows, while keeping piglets at ideal temperatures, is the focus of this project. A cooling pad was built with copper pipes inside a high-density polyethylene board, covered by an aluminum plate. Experimental treatments included cool water flowing through the copper pipes at different levels depending on the specific sow. Intervals …

Purdue Hog Cooling Pad Experience, Marco Baez

American Journal of Rising Scholar Activities

The demand for food is increasing with the growing population. The pork industry is currently thriving and will continue to prosper as long as sows continue to reproduce. However, the reproduction of pigs is currently facing the problem of heat stress. Environmental temperatures are reaching extremes, and lactating sows produce less milk for offspring when they are in hot weather. The main reason that they produce less is because of undernourishment. Sows eat less when hot, because when they do eat, it actually causes them to heat-up. The goal of the overall cooling pad effort is to reduce the heat …

With the development of the economy and society, more attention is being paid to energy costs and the potential environmental pollution caused by vegetable cultivation. The aim of this study was to investigate the impacts of zero discharge of nutrient solutions on cucumber growth, leaf photosynthesis, and the yield and quality of cucumber under greenhouse conditions. The results show that zero discharge treatment did not change plant height, stem diameter, internode length, leaf area, net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci), transpiration rate (Tr), and leaf relative chlorophyll content on the most measurement days. Only Pn …

Infection Avoidance Behaviors Across Vertebrate Taxa: Patterns, Processes, And Future Directions, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning

Biology, Chemistry, and Environmental Sciences Faculty Books and Book Chapters

An infected animal can behave, smell, sound, and look very different from a healthy version of itself. The same is true when comparing habitats, food, or water sources contaminated with parasite infectious stages to their uncontaminated counterparts. All these differences provide cues or indications of disease risk and thus allow uninfected animals to modify their behaviors in ways that alter disease transmission. This chapter focuses on prophylactic behaviors: host behaviors that reduce the risk of infection. It provides an overview of how infection avoidance behaviors are triggered, then summarizes the avoidance behaviors known to occur in vertebrates, giving special attention …

Why Not Both Nature And Nurture: Using Behavioral Genetic Markers As Sentencing Factors, Seely Kaufmann

Richmond Journal of Law & Technology

On the evening of July 1, 2013, Amos Wells was upset that his pregnant girlfriend, Chanice Reed, would not answer his calls. He then drove to where she, her mother Annette, and ten-year-old brother Eddie, lived. After arguing with Chanice and yelling at the top of his voice in a “bone-chilling scream,” Wells retrieved a handgun from his Chevrolet Tahoe parked in front of the house, and shot Chanice in the front yard as she screamed, “No, no, no.” Her mother then tried to bat the gun away before he shot her too. Further shots were heard before Wells finally …

Coupled Oscillators: Protein And Acoustics, Angelique N. Mcfarlane

Global Variation In Nonstructural Carbohydrate Stores In Response To Climate, Meghan Blumstein, Jess T. Gersony, Jordi Martínez-Vilalta, Anna Sala

Biological Sciences: Faculty Publications

Woody plant species store nonstructural carbohydrates (NSCs) for many functions.While known to buffer against fluctuations in photosynthetic supply, such as at night, NSC stores are also thought to buffer against environmental extremes, such as drought or freezing temperatures by serving as either back-up energy reserves orosmolytes. However, a clear picture of how NSCs are shaped by climate is still lack-ing. Here, we update and leverage a unique global database of seasonal NSC storage measurements to examine whether maximum total NSC stores and the amount of soluble sugars are associated with clinal patterns in low temperatures or aridity, indicating they may …

Women Of The Scriptures In The Relief Society Magazine: An Analysis Of The Role Of Language In Maintaining Gender Norms, Kayla Bach

The protostome leucokinin (LK) signaling system, including LK peptides and their G protein-coupled receptors, has been characterized in several species. Despite the progress, molecular mechanisms governing LK peptide–receptor interactions remain to be elucidated. Previously, we identified a precursor protein for Aplysia leucokinin-like peptides (ALKs) that contains the greatest number of amidated peptides among LK precursors in all species identified so far. Here, we identified the first ALK receptor from Aplysia, ALKR. We used cell-based IP1 activation assays to demonstrate that two ALK peptides with the most copies, ALK1 and ALK2, activated ALKR with high potencies. Other endogenous ALK-derived peptides …

Polymorphism & Parasites: Structure, Diversity And Selection Of The Mhcii Genes In A Weakly Electric Fish, Brachyhypopomus Occidentalis, Bruna L. Silva

Graduate Masters Theses

The major histocompatibility complex (MHC) class II molecules play a key role in inducing an immune response, by presenting foreign peptides to T-lymphocytes. They are considered one of the most polymorphic genes in the vertebrate genome and diversity has been associated with species diversification mediated by parasite, viral and bacterial infections. While MHC genes are well documented in teleost fish, none thus far have been described in the Gymnotiform order – a highly diverse group of neotropical electric fishes. Using a combination of a recently annotated genome and whole genome resequencing data, I identified and characterized both the classical MHCII …

Associations Between The Content And Level Of Parent Concerns Pre-Diagnosis And Timeliness Of Autism Screening And Diagnostic Evaluation Among A Diverse Sample Of Children In Part C Early Intervention, Kohrissa Joseph

Graduate Masters Theses

Though autism can be diagnosed as early as 18 months for many children, the current average age of diagnosis is between 3 and 4 years old. Children of color are diagnosed even later. Several studies have examined this disparity and have found that one significant contributor is pediatric providers’ screening practices. Though the American Academy of Pediatrics (AAP) recommends autism specific screening at 18- and 24-month well-child visits, many pediatricians report only screening if they are concerned or if the parent mentions a concern. In light of recent findings that Black and Latinx parents may have fewer autism-related concerns than …

The Role Of Emotion Regulation In Long-Term Weight Loss Maintenance: A Cross-Sectional Study, Karyn M. Aiello

Graduate Masters Theses

While many weight loss interventions have resulted in significant weight loss, maintaining that weight loss long-term continues to be challenging for most, with long-term weight loss maintenance (LTWLM) rates as low as 20% among participants of clinical weight loss studies. Those who struggle with LTWLM exhibit many shared characteristics, including lower mental health composite scores; high levels of perceived stress; and lower rates of adherence to WLM behaviors. One explanation for this might be that emotion regulation (ER) skills are stronger among those who are successful at LTWLM, and therefore more successful at self-regulating for the goal of LTWLM.

Accurate and efficient classification of variant pathogenicity is critical for research and clinical care. Using data from three large studies, we demonstrate that population-based associations between rare variants and quantitative endophenotypes for three monogenic diseases (low-density-lipoprotein cholesterol for familial hypercholesterolemia, electrocardiographic QTc interval for long QT syndrome, and glycosylated hemoglobin for maturity-onset diabetes of the young) provide evidence for variant pathogenicity. Effect sizes are associated with pathogenic ClinVar assertions (P < 0.001 for each trait) and discriminate pathogenic from non-pathogenic variants (area under the curve 0.82-0.84 across endophenotypes). An effect size threshold of ≥ 0.5 times the endophenotype standard deviation nominates up to 35% of rare variants of uncertain significance or not in ClinVar in disease susceptibility genes with pathogenic potential. We propose that variant associations with quantitative endophenotypes for monogenic diseases can provide evidence supporting pathogenicity.

“The Circle Of Your Acquaintance”: Early 19th Century Ceramic Symbolism And Constructions Of Black Womanhood At The Boston-Higginbotham House, Nantucket, Ma, Lissa J. Herzing

Graduate Masters Theses

During the early 19th century, ideologies of womanhood were beginning to solidify in the national discourse of the United States. The concept of domesticity, the process of homemaking through material and spiritual means, was a key aspect of womanhood during this time, the transition from the Early Republic to the Victorian period. These ideals were prescribed to white middle- and upper-class women but were altered by Black women to serve their needs and adopted to combat negative stereotypes of Black people in a society permeated with racism. This was evident in the work of Maria W. Stewart, the first Black …

Despite having similar histologic features, patients with high-grade serous ovarian carcinoma (HGSC) often experience highly variable outcomes. The underlying determinants for long-term survival (LTS, ≥10 years) versus short-term survival (STS, < 3 years) are largely unknown. The present study sought to identify molecular predictors of LTS for women with HGSC. A cohort of 24 frozen HGSC samples was collected (12 LTS and 12 STS) and analyzed at DNA, RNA, and protein levels. OVCAR5 and OVCAR8 cell lines were used for in vitro validation studies. For in vivo studies, we injected OVCAR8 cells into the peritoneal cavity of female athymic nude mice. From RNAseq analysis, 11 genes were found to be differentially expressed between the STS and LTS groups (fold change > 2; false discovery rate < 0.01). In the subsequent validation cohort, transmembrane protein 62 (TMEM62) was found to be related to LTS. CIBERSORT analysis showed that T cells (follicular helper) were found at higher levels in tumors from LTS than STS groups. In vitro data using OVCAR5 and OVCAR8 cells showed decreased proliferation with TMEM62 overexpression and positive correlation with a longevity-regulating pathway (KEGG HSA04213) at the RNA level. In vivo analysis using the OVCAR8-TMEM62-TetON model showed decreased tumor burden in mice with high- vs. low-expressing TMEM62 tumors. Our results demonstrate that restoring TMEM62 may be a novel approach for treatment of HGSC. These findings may have implications for biomarker and intervention strategies to help improve patient outcomes

Thermodynamic And Structural Quantification Of Metal Ions Binding To The Antimicrobial Peptide Calcitermin, Sohee Choi

Master's Theses

Over the past several decades the number of antibiotic resistant bacteria has grown dramatically, in part due to the over-prescription of antibiotics. This rise in antibiotic resistance has led to development of novel antibiotics. An attractive alternative to treat bacterial infections may be the use of antimicrobial peptides due their little-known resistance from bacteria. One such peptide is calcitermin (VAIALKAAHYHTHKE), a 15-residue peptide found in human airways. Calcitermin has antimicrobial properties that target Gram-positive bacteria and is most active in acidic buffer (pH 5.4) due to protonation of its three histidine residues, which allows it to interact with the negatively …
