Developing Genetic Resources Within The Chenopodium Genus To Advance Quinoa Breeding And The De Novo Domestication Of C. Berlandieri, Clayton David Ludwig

Doctoral Dissertations

Quinoa (Chenopodium quinoa), an orphan crop native to South America, is tolerant of drought and saline soils and produces a highly nutritious grain. Given these qualities, the demand for this pseudocereal has been steadily increasing, and quinoa breeding programs can now be found throughout the world. I believe the introduction of quinoa-like cultivars developed specifically for Northern New England (NNE) with the region’s climate and disease pressures taken into consideration will benefit local farmers and consumers. Quinoa breeding efforts must consider its allopolyploid (2n = 4x = 36: AABB) genome composition as well as its reticulate ancestry, having descended via …

Kinesiology

Background: Taking inspiration from the classical 1974, “moving room experiment” by Lee and Aronson, a “virtual moving room paradigm (Vroom)” was designed using virtual reality (VR) to assess postural control behavior. Methods: Thirty healthy adults (age: 21 ± 1 years; height: 166.5 ± 7.3 cm; mass: 71.7 ± 16.2 kg) were tested for postural stability in a virtual moving room paradigm (Vroom). The Vroom consisted of randomized virtual and visual perturbations of the virtual room moving toward and away from the individual, during both unexpected and expected trials. Objective postural sway variables and subjective experiences to VR using the simulator …

Examining The Relations Between Obsessive Compulsive Disorder And Quality Of Life In A Transdiagnostic Eating Disorder Sample., Madison Rose Ortman

College of Arts & Sciences Senior Theses

Background: Eating disorders (EDs) are life threatening psychological disorders characterized by obsessions related to food, weight, and exercise. The presence of an eating disorders has been linked to poorer quality of life (QOL) and clinical impairment. Obsessive compulsive disorder (OCD) is a psychiatric disorder characterized by intrusive thoughts and ritualistic behaviors. EDs and OCD have similar symptom structure as well as similar independent relationships to QOL. The present study aimed to validate these relationships and extend the findings into a more fine-grained symptom analysis of the relationship between EDs, OCD and QOL. Method: Participants (N = 109) were those …

The lifespan extension induced by 40% caloric restriction (CR) in rodents is accompanied by postponement of disease, preservation of function, and increased stress resistance. Whether CR elicits the same physiological and molecular responses in humans remains mostly unexplored. In the CALERIE study, 12% CR for 2 years in healthy humans induced minor losses of muscle mass (leg lean mass) without changes of muscle strength, but mechanisms for muscle quality preservation remained unclear. We performed high-depth RNA-Seq (387–618 million paired reads) on human vastus lateralis muscle biopsies collected from the CALERIE participants at baseline, 12- and 24-month follow-up from the 90 …

Cultural Control Tactics For Managing Spotted Wing Drosophila, Drosophila Suzukii, In New Hampshire Highbush Blueberry, Catherine Doheny Coverdale

Master's Theses and Capstones

Spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an economically important pest that damages small, soft-skinned fruits. Female spotted wing drosophila (SWD) have a heavily sclerotized, serrated ovipositor which allows them to lay their eggs in ripe and ripening fruits. Woven polyethylene weed mat has been reported to influence ambient temperature and relative humidity within blueberry canopies. There is a lack of context-specific evidence regarding the mechanisms impacting its efficacy and how it may interact with other control methods, like crop sanitizer sprays containing peroxyacetic acid (PAA) and hydrogen peroxide (HP).This study was a two-year, split-plot field experiment in …

Single-Cell Analysis In Hypersaline Brines Predicts A Water-Activity Limit Of Microbial Anabolic Activity, Emily R. Paris, Nestor Arandia-Gorostidi, Benjamin Klempay, Jeff S. Bowman, Alexandra Pontefract, Claire E. Elbon, Jennifer B. Glass, Ellery D. Ingall, Peter T. Doran, Sanjoy M. Som, Britney E. Schmidt, Anne E. Dekas

Faculty Publications

Hypersaline brines provide excellent opportunities to study extreme microbial life. Here, we investigated anabolic activity in nearly 6000 individual cells from solar saltern sites with water activities (aw) ranging from 0.982 to 0.409 (seawater to extreme brine). Average anabolic activity decreased exponentially with aw, with nuanced trends evident at the single-cell level: The proportion of active cells remained high (>50%) even after NaCl saturation, and subsets of cells spiked in activity as aw decreased. Intracommunity heterogeneity in activity increased as seawater transitioned to brine, suggesting increased phenotypic heterogeneity with increased physiological stress. No microbial activity was detected in the …

The Impact Of The Covid-19 Pandemic Response On Food Safety Violations Observed In Southern Nevada Food Establishments, Samantha Morales

UNLV Theses, Dissertations, Professional Papers, and Capstones

Food poisoning is a common term used to describe what is actually foodborne illness. Despite the fact these illnesses can become deadly, foodborne illnesses are endemic and common in the United States. Nonetheless, they are completely preventable simply by following proper food safety procedures. The Food and Drug Administration identified the most common foodborne pathogens responsible for most foodborne infections, as well as the five risk factor categories to target in order to decrease the risk of cases and outbreaks.

To ensure foodborne outbreaks and cases are prevented, health authorities are tasked with conducting routine inspections on permitted food establishments. …

Assessing The Effects Of Non-Native Flowering Plants And Anti-Herbivory Plastic (Vexar®) Tubes On Insect Visitation To Native Plants, Emily R. Sun

Boise State University Theses and Dissertations

Bees (Hymenoptera: Apoidea) are among the most prominent pollinators of the flowering plants and play an essential role in maintaining ecosystem function. Disruption of plant-pollinator interactions is a growing global concern because of the implications for biodiversity, ecosystem health, and agriculture. The incursion of non-native plants globally is seen to adversely affect native plants and alter plant-pollinator communities. In chapter one, I examined the effects of a non-native weed, Sisymbrium altissimum (tall tumblemustard), on bee visitation to nearby native Sphaeralcea munroana (Munro’s globemallow), including genera-specific differences among bees. The most common bee genera were Andrena, Colletes, Diadasia, Halictus, and …

Mapping Density And Distribution Of Ptarmigan And Arctic Ground Squirrels Within Gyrfalcon Breeding Territories In Western Alaska, Michaela L. Gustafson

Boise State University Theses and Dissertations

Shifting climate patterns are modifying Arctic habitats, stressing the need to understand how rapid climate and habitat changes affect Arctic trophic webs. Despite their crucial role in illuminating the impacts of Arctic changes and their ripple effects on predators, like Gyrfalcons, small Arctic primary consumers remain insufficiently studied across their range. To address this gap, I sought to estimate the distribution and abundance of Gyrfalcons' top three prey species (Willow Ptarmigan, Rock Ptarmigan, and Arctic ground squirrels) within Gyrfalcon breeding territories on the Seward Peninsula, Alaska, USA. I also aimed to discern the relationships between different habitats and species’ abundance. …

Integrating Lawyers Into Perinatal Care Teams To Address Unmet, Health-Harming Legal Needs, Loral Patchen, Roxana Richardson, Asli Mccullers, Vicki W. Girard

Georgetown Law Faculty Publications and Other Works

Across the United States, historically imposed structural, social, and environmental variables are intimately connected to poor obstetric outcomes and high maternal and infant mortality rates among Black pregnancy-capable people. Efforts to diminish the effect of these variables include integrating screening for social determinants of health during the perinatal period and treating them with social services, mental health support, and other referrals, including connections to community-based resources. Although helpful, some of these social determinants cannot be overcome without legal advocacy. Medical–legal partnerships, which integrate lawyers into health care, fill this gap. This commentary by an interprofessional team of authors relies on …

Serum amyloid A (SAA) is a family of proteins, the plasma levels of which may increase >1000-fold in acute inflammatory states. We investigated the role of SAA in sepsis using mice deficient in all three acute-phase SAA isoforms (SAA-TKO). SAA deficiency significantly increased mortality rates in the three experimental sepsis mouse models: cecal ligation and puncture (CLP), cecal slurry (CS) injection, and lipopolysaccharide (LPS) treatments. SAA-TKO mice had exacerbated lung pathology compared to wild-type (WT) mice after CLP. A bulk RNA sequencing performed on lung tissues excised 24 h after CLP indicated significant enrichment in the expression of genes associated …

Leukocyte Cell-Derived Chemotaxin 2 Correlates With Pediatric Non-Alcoholic Fatty Liver Disease., Diego Paine-Cabrera, Lisa Harvey, Dakota R. Robarts, Michele T. Pritchard, John Thyfault, Steven A. Weinman, Udayan Apte, Voytek Slowik

Manuscripts, Articles, Book Chapters and Other Papers

Non-alcoholic fatty liver disease (NAFLD), newly renamed metabolic dysfunction-associated liver disease (MASLD), is a leading cause of liver disease in children and adults. There is a paucity of data surrounding potential biomarkers and therapeutic targets, especially in pediatric NAFLD. Leukocyte cell-derived chemotaxin 2 (LECT2) is a chemokine associated with both liver disease and skeletal muscle insulin resistance. Our aim was to determine associations between LECT2 and common clinical findings of NAFLD in pediatric patients. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum LECT2 concentrations in children (aged 2-17 years) with and without NAFLD. LECT2 concentrations were then correlated to …
