Regional Effects Of Streptozotocin-Induced Diabetes On Shortening And Calcium Transport In Epicardial And Endocardial Myocytes From Rat Left Ventricle, Manal M.A. Smaill, Muhammad A. Qureshi, Anatoliy Shmygol, Murat Oz, Jaipaul Singh, Vadym Sydorenko, Alya Arabi, Frank C. Howarth, Lina Al Kury

All Works

© 2016 The Authors. In the heart, the left ventricle pumps blood at higher pressure than the right ventricle. Within the left ventricle, the electromechanical properties of ventricular cardiac myocytes vary transmurally and this may be related to the gradients of stress and strain experienced in vivo across the ventricular wall. Diabetes is also associated with alterations in hemodynamic function. The aim of this study was to investigate shortening and Ca2+ transport in epicardial (EPI) and endocardial (ENDO) left ventricular myocytes in the streptozotocin (STZ)-induced diabetic rat. Shortening, intracellular Ca2+ and L-type Ca2+ current (ICa,L) were measured by video detection, …

Evaluation Of Parameter Estimation And Field Application Of Transgenerational Genetic Mark-Recapture, Ryan W. Whitmore

Cal Poly Humboldt theses and projects

Use of a genetic-based analogue of the traditional mark-recapture method (transgenerational genetic mark-recapture, tGMR) is rapidly expanding as a means to estimate total escapement of Pacific salmon. The tGMR approach is similar to the simple Lincoln-Peterson mark-recapture method. In tGMR, adults returning to fresh water to spawn are collected in the first sampling occasion and their juvenile offspring that are migrating out to sea are collected during the second sampling occasion. Recaptures are determined by the number of parent-offspring pairs identified through genetic parentage analysis of the adult and juvenile collections. Two versions of tGMR are currently in use, referred …

This thesis includes a series of terse vignettes and a pastoral section. Both groups of poems share a connection to imagism and are invested in latency, given that the fraught images hint at violences just beyond the reader's sensual periphery.

Color Associations As Advertising Strategies: An Analysis Of Consumer Attitudes Toward The Healthfulness Of Energy Bar Packaging, Rachel Lotz

University Honors Theses

Color plays a strong role in shaping consumers’ attitude toward brands, expectations, and likeability in the field of advertising. Associations with colors are formed within consumers’ culture and are often universal in meaning. Through three studies, the role of color in relationship to perceived healthfulness on energy bar packaging is observed. The results show a strong correlation between a particular color associated with healthfulness due to preconceived color associations often highlighted in advertising strategies. However the results raised unexpected, yet insightful correlations with other colors, which participants identified as healthy. When participants were asked to pick the energy bar that …

Integration Of Movement/Posture: A Dynamic Adaptive Process Model, Daniel A. Akins

University Honors Theses

Structural Integration (SI) is a process of manual therapy and sensorimotor education that aims to facilitate sustainable improvement in whole-body biomechanical functioning and a sense of ease and coherence in normal movement/posture. Traditional and currently widespread explanations for the physiological mechanisms underlying SI theory and practice have focused on notions of fascial tissue change and postural alignment, while recent challenges to these explanations advocate a shift away from these interests toward a neurocentric model that emphasizes movement, pain, and biopsychosocial factors. SI seeks to professionalize and become an auxiliary to healthcare, so it must embrace scientific standards while maintaining its …

Defining Protein Interactions: Ankle Link Proteins Of Stereocilia In Hair Cells, Ladan Yazdidoust

University Honors Theses

Hearing loss presenting without any other defects is referred to as nonsyndromic, whereas hearing loss in combination with one or more defects is referred to as syndromic hearing loss. Usher syndrome, one example of syndromic hearing loss, is a genetic disorder that affects both hearing and vision. There are several genes associated with Usher syndrome. The genes GPR98 and USH2A are critical for ankle link formation and when mutated result in deafness. Our lab (Barr-Gillespie Lab at OHSU) is interested in further characterizing the protein-protein interactions required to form the ankle links. This includes two genes (PDZD7 and MYO7A …

Precipitation Intensity Required For Landslide Initiation In Rwanda, Angela N. Piller

University Honors Theses

Rwanda has a high density of landslides, heavy precipitation events and a shortage of resources to study them, making it an excellent candidate for study using satellite-based remote sensing data. To assess landslide hazards countrywide, I first built a landslide inventory of 254 landslides and used a statistical methodology. Using logistic regression on 24 test variables, I determined that slope and population density are statistically most relevant to landslide occurrence in Rwanda. A preliminary predictive hazard map for Rwanda was produced, with an overall predictive accuracy of 79.6%. Second, I worked to define a relationship between precipitation intensity and landslide …

Carbon Dioxide Concentrations: An Examination Of Carbon Sequestration Via Global Reforestation, Jordan Bertagnolli

University Honors Theses

Deforestation has resulted in a dramatic change to Earth’s landscape, climate, and ecosystems. To date, 46% of all forests have been cut since the onset of agriculture about 12,000 years ago (Crowther et al., 2015). During that same time, greenhouse gas concentrations have grown by 51.8% (Crowther et al., 2015). A solution to this problem could be vast carbon capture initiatives involving tree planting. Historical reforestation efforts have thus far been conducted regionally and currently make up less than 1% of the forest cover that they are replacing. With current CO₂ concentrations at a record high of 402.26 ppm …

Fitness And Fatness: The Conflation Of Weight With Health, And The Consequences Of Fat-Shaming, Kristin Spurkland

University Honors Theses

Obesity is widely accepted as one of the major health crises facing the United States, and increasingly, the world. Labeled a disease by the American Medical Association, and frequently characterized as an epidemic, obesity is the target of high profile national health interventions, media campaigns, and a multi-billion dollar self-help industry. The message produced by public health agencies is that obesity is a killer, and that reducing weight is a beneficial and achievable goal generating many positive health outcomes. This paper presents two primary arguments that counter the prevailing attitudes towards obesity: that as a stand-alone measure, Body Mass Index …

Animal Hoarding: An In Depth Look At The Issues And Interventions, Amanda Mooneyham

University Honors Theses

Animal hoarding cases in regard to 501(c)3 nonprofit agencies have been on the rise in recent decades and current intervention strategies are struggling to address this complex social problem. Animal hoarding not only affects the animals being abused, but it has adverse effects on humans and the environment. This paper examines the complexities surrounding animal hoarding, specifically focusing on the rescue hoarder mentality. The current intervention methods used are criminal prosecution, civil/regulatory enforcement, and mental health evaluations/treatments. Criminal prosecution is effective for some animal hoarders, but a lack of laws protecting animals along with animals being viewed as property translates …

The Controversy Over Community Water Fluoridation : An Analysis Of Its Effects And Reasons Behind The Arguments, Grace Noda

University Honors Theses

This thesis explores different viewpoints on the history of community water fluoridation and reflects on the arguments made by the pro- and anti-fluoridationists in the United States. Community water fluoridation has been controversial in the United States since it was first proposed in 1945. Since then, fluoridation has been a major factor in reducing the prevalence and severity of dental cavities in the United States (U.S.).

Fluoride safely and effectively prevents dental cavities and is available from multiple sources. Community water fluoridation is one of these sources, providing fluoride to all people regardless of their position within the community. Even …

Expression And Purification Of Recombinant Protein To Generate A Monoclonal Antibody To The Px Domain Of Tks5 Α Isoform In Cancer Cells, Eva Y. Chan

University Honors Theses

Tyrosine kinase Src substrates, Tks4 and Tks5, are involved in the formation of podosomes and invadopodia during cell migration and cancer cell metastasis. Most recently, the α isoform of Tks5 has been discovered highly expressed in cancer cells, suggesting that the Tks5 α isoform plays essential roles in the regulation of invadopodia. In the Tks protein family, only the Tks5 α isoform contains a PX domain, which binds an important second messenger, PI (3,4) P2. Using a monoclonal antibody as an antigen-specific-probe to detect the protein of interest could be a useful tool that would provide a highly specific recognition …

Regarding The Treatment Of Women, Where Did Jesus Set The Bar?, Katerina Paetzhold

University Honors Theses

This thesis crafts an argument for greater female education, teaching, and leadership within modern day Christian churches. By examining three key interactions between Jesus and women as recorded in the four canonical gospels, a clear example for gender equality within Christianity emerges. The manner in which Jesus speaks with the Samaritan Woman, Mary of Bethany, and the women at the resurrection, as well as the roles and responsibilities he places on them demonstrates that Christ saw women as capable of learning, teaching, and leading. As the canon of Christianity, Jesus' life on earth is the template that sets the bar …

Cofactor Binding Determinants In The Nadph-Dependent Nitrile-Oxidoreductase Quef, Spencer William Cohen

University Honors Theses

The NADPH-dependent nitrile-oxidioreductase, QueF is the only known enzyme capable of reducing a nitrile group to an amine. This ability makes it an attractive alternative to conventional industrial nitrile reduction. Understating how QueF binds NADPH may lead to the development of an enzyme capable of using the less expensive reductive cofactor NADH. A cofactor docking model indicates that key residues, Q60 and Y21, interact with the ribose phosphate moiety unique to NADPH. Mutants of these residues (Q60A, Q60N, Q60E, Y21A and Y21F) were developed for steady-state kinetic analysis. Modification to either residue resulted in a decrease in binding and catalytic …

Fetal Stress And Neurogenesis In Thamnophis Sirtalis Parietalis, Kalera Stratton

University Honors Theses

Little is currently known about normal brain development and the growth of new nerve cells, known as neurogenesis, in most species, let alone how exposure to prenatal stress affects these processes. Using red-sided garter snakes as our animal model, we have a unique opportunity to study the impact of exposure to elevated maternal glucocorticoids, commonly known as "stress hormones", on brain development. This species is viviparous, with a proto-placental structure through which developing fetuses receive nutrients from the dam. Adult snakes also exhibit high rates of seasonal changes in neurogenesis. We captured mated female snakes and treated one-third of them …
