Critical Embodied Praxis For Social Justice And Peace Educators: A Story Of Personal Transformation Through Analysis Of My Jewish And Settler Identities, Cara Michelle Silverberg

Capstone Collection

In this paper, I examine definitions of and relationships between violence, oppression, peace, liberation, and embodiment in the context of critical pedagogy in order to construct a theory of critical embodied praxis for social justice and peace educators. Considering the body to be a tangible vessel through which narratives and mechanisms of violence are expressed and maintained, I explore the potential of the body to be a vessel through which liberatory narratives may be generated and shared. After constructing a theory of critical embodied praxis, I illustrate this framework in action through a personal narrative that explores the intersections …

Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom

Masters Theses

Mammalian dental anatomy has evolved in accordance with the physical properties of its diet, and multiple features on each tooth have specific functions related to the breakdown of food during mastication and ingestion. Tooth structure is under tight genetic control and much of the anatomical variation in dentition across species is related to adaptation to a specific dietary regime. This diet-dentition relationship can be exploited to reconstruct mammalian diets from fossil specimens through calculation of dental topographic metrics. To date, most studies of dietary reconstruction using dental topography have focused on mandibular molars; thus, this study seeks to test whether …

The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring: Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species, Robert J. Posont

Department of Animal Science: Dissertations, Theses, and Student Research

Our first study identified the effects of maternal inflammation-induced intrauterine growth restriction (MI-IUGR) on growth and muscle glucose metabolism in offspring supplemented with curcumin. MI-IUGR lambs exhibited asymmetric growth restriction at birth and 30d of age, but normal glucose-stimulated insulin secretion. Hindlimb glucose oxidation was reduced by MI-IUGR and not improved by curcumin supplementation. Ex vivo muscle glucose oxidation was reduced by MI-IUGR but improved somewhat by curcumin. These finding indicate that fetal programming responses to MI contribute to neonatal growth and metabolic deficits. Neonatal curcumin supplementation had minimal effect on growth deficits but may improve glucose metabolism. …

In the first stage, participants performed 1 set of …

The Effects Of Bacterial Endotoxin Lps On Synaptic Transmission At The Neuromuscular Junction, Robin L. Cooper, Micaiah Mcnabb, Jeremy Nadolski

Biology Faculty Publications

The direct action of bacterial lipopolysaccharides (LPS) endotoxin was shown to enhance synaptic transmission and hyperpolarize the membrane potential at low doses, but block glutamatergic receptors and decrease observable spontaneous events at a high dosage. The dosage effects are LPS type specific. The hyperpolarization is not due to voltage-gated potassium channels or to activation of nitric oxide synthase (NOS). The effects are induced directly by LPS, independent of an immune response.

Impact Of Intrinsic Physiological Factors In The Population Recovery Of Myotis Lucifugus (Little Brown Myotis) From White-Nose Syndrome, Caroline Burke, Caitlin Looney, Alissah Sillah, Christopher Richardson

Lesley University Community of Scholars Day

White-nose Syndrome (WNS) has decimated populations of hibernating bats in the US. In particular, Myotis lucifugus (little brown myotis) has been one of the most affected. We investigated the energetic cost of innate immune response and Pseudogymnoascus destructans (Pd) fungal activity on post-hibernating little brown myotis and the link with the recovery of local populations in New England from WNS. We captured bats at one of each of 4 colonies in Eastern Massachusetts and Southern New Hampshire, consecutively, every 14 days to minimize disturbance to the colony. Blood samples were collected from each bat. Respirometry trials were performed on each …

Computational Modelling Of Peptides Containing Non-Standard Amino Acids, David W. Kastner

Undergraduate Honors Theses

Peptides represent a class of abundant and potent pharmaceutic compounds. Despite their appeal, the design, synthesis, and engineering of biologically relevant peptides remain a challenge. Chapter 1 introduces the various computational methods that will be used. Chapter 2 focuses on the incorporation of a special class of amino acids called bulky dehydroamino acids into the turn of β-hairpins to proteolytically stabilize peptides. Our results suggest that dehydroamino acids confer proteolytic stability by favoring a more folded state. Chapter 3 describes the structural calculations of a rare anticancer peptide called Yaku’amide using a combined molecular mechanics/quantum mechanics hybrid method. The …

A Critical Evaluation Of The Biological Construct Skeletal Muscle Hypertrophy: Size Matters But So Does The Measurement, Cody T. Haun, Christopher G. Vann, Brandon M. Roberts, Andrew D. Vigotsky, Brad J. Schoenfeld, Michael D. Roberts

Publications and Research

Skeletal muscle is highly adaptable and has consistently been shown to morphologically respond to exercise training. Skeletal muscle growth during periods of resistance training has traditionally been referred to as skeletal muscle hypertrophy, and this manifests as increases in muscle mass, muscle thickness, muscle area, muscle volume, and muscle fiber cross-sectional area (fCSA). Delicate electron microscopy and biochemical techniques have also been used to demonstrate that resistance exercise promotes ultrastructural adaptations within muscle fibers. Decades of research in this area of exercise physiology have promulgated a widespread hypothetical model of training-induced skeletal muscle hypertrophy; specifically, fCSA increases are accompanied by …

Participants ran a 2.4 km (1.5 m) bout, at prescribed RPE4, and another at prescribed RPE7, following 10 min passive recovery. Separate 2 (trial) x 6 …

Deciphering The Consequences Of Yolk Testosterone Metabolism In Birds, Nicole A. Campbell

Theses and Dissertations

Maternal steroids transferred to eggs can elicit permanent effects on various aspects of offspring phenotype. Although, testosterone was thought to be a key mediator of maternal effects in birds, we now know that vertebrate embryos actively regulate their exposure to maternal testosterone through steroid metabolism, suggesting testosterone metabolites may elicit the observed phenotypic effects. To address the role steroid metabolism plays in mediating yolk testosterone effects, we used European starling (Sturnus vulgaris) eggs to characterize the timing of testosterone metabolism and determine whether etiocholanolone, a prominent testosterone metabolite in avian embryos, is capable of influencing early embryonic development. Tritiated testosterone …

Dennd5b Regulates Intestinal Triglyceride Absorption And Body Mass, Scott M. Gordon, Edward B. Neufeld, Zhihong Yang, Milton Pryor, Lita A. Freeman, Xiao Fan, Iftikhar J. Kullo, Leslie G. Biesecker, Alan T. Remaley

Saha Cardiovascular Research Center Faculty Publications

Regulation of lipid absorption by enterocytes can influence metabolic status in humans and contribute to obesity and related complications. The intracellular steps of chylomicron biogenesis and transport from the Endoplasmic Reticulum (ER) to the Golgi complex have been described, but the mechanisms for post-Golgi transport and secretion of chylomicrons have not been identified. Using a newly generated Dennd5b^−/− mouse, we demonstrate an essential role for this gene in Golgi to plasma membrane transport of chylomicron secretory vesicles. In mice, loss of Dennd5b results in resistance to western diet induced obesity, changes in plasma lipids, and reduced aortic atherosclerosis. In …

Physiological Response To Exercise With Naturally-Occurring Carbon Dioxide Exposure, Megan Johnson

UNO Student Research and Creative Activity Fair

BACKGROUND: Carbon dioxide (CO₂) plays a normal part in gas exchange and acid-base equilibrium in the human body. With added stress or exposure, CO₂ levels can accumulate in the blood and tissues, causing hypercapnia. Research has shown that exposure to CO₂ at 4% or 40,000 ppm will cause cardio-respiratory changes, both at rest and during exercise. Lower levels may still cause changes under conditions of added stress, but this has not been elucidated. Preliminary data from our laboratory chamber suggests physiological changes at levels of CO₂ reaching 0.08% or 8,000 ppm during experiments with exercising …

Effect Of Local Cold Application During Exercise On Mitochondrial Gene Expression, Ben Meister

UNO Student Research and Creative Activity Fair

BACKGROUND: Different modes of exercise and temperatures can elicit different responses in mitochondrial gene expression. Stresses including exercise and cold exposure act to trigger the transcription of genes associated with mitochondrial growth (biogenesis). Traditional endurance exercise is known to have a potent effect on mitochondrial growth biogenesis. However, limited knowledge exists on the effect of local cold application during endurance exercise. Additionally, it is currently unknown how cold exposure impacts mitochondrial breakdown (mitophagy). PURPOSE: Therefore, the purpose of this study is to determine the impact of local muscle cooling during endurance exercise on human skeletal muscle gene expression related to …
