On The Road To Better Health? Impacts Of New Market Access On Food Security, Nutrition, And Well-Being In Nepal, Himalaya, Michelle Ursula Grocke Jan 2016

On The Road To Better Health? Impacts Of New Market Access On Food Security, Nutrition, And Well-Being In Nepal, Himalaya, Michelle Ursula Grocke

Graduate Student Theses, Dissertations, & Professional Papers

The first road to be built into Humla, Nepal has connected this once-remote Himalayan region to a market in China. This dissertation research assesses the impacts of this road on villagers’ food security, diet and nutrition, and subjective well-being, and investigates the link between objective and subjective health outcomes. The primary aim of this study is to decipher whether villagers’ ‘proximity to road’ is the strongest predictor of the aforementioned health outcomes, or whether other sociocultural and economic variables play a more significant role. A mixedmethods approach and a case-control ethnographic research design were implemented in order to investigate this …

In an effort to understand limitations on the effectiveness of global programs, this research addresses the following question: What do physicians know about global programs for TB? Mixed methods, involving both quantitative and qualitative data, were used to obtain the results of …


Integration Of Movement/Posture: A Dynamic Adaptive Process Model, Daniel A. Akins Jan 2016

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 …

Gi Zoonoses In Companion Pets Of The Homeless : The Effects Of Environment And Behavior On The Prevalence Of Gi Parasites, And The Role Of Veterinarians In Public Health Education, Matthew Edwards

University Honors Theses

Veterinarians are the front-line in the world of pet-health and zoonoses which means they are also at the front-line of human health and have an important role of educating clients on behaviors that would both reduce the risk of human and pet contracting a disease. In this study we collected 85 stool samples in Portland OR, USA and examined these by centrifugal fecal flotation, direct smears and for a small number (n=15) ELISA snap-tests. Parasitic prevalence was found to be 27.1% total including 2.4% Ancyclostoma Sp., 4.7% Cryptosporidium Sp., 7.1% Cystoisopora Sp., 9.4% Taenia Sp., 2.4% Giardia Sp., and 2.4% …


Fitness And Fatness: The Conflation Of Weight With Health, And The Consequences Of Fat-Shaming, Kristin Spurkland Jan 2016

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 …

Since PQRS will continue to be used in its current form through 2017 and will be incorporated into a new program starting in 2018, it is necessary to assess the weakness and strengths of this program. Addressing these are crucial for the successful continuation of PQRS and improving …


Review: A Novel Multiple Sclerosis Model Utilizing Cuprizone And Rapamycin, Mara Bahri Jan 2016

Review: A Novel Multiple Sclerosis Model Utilizing Cuprizone And Rapamycin, Mara Bahri

University Honors Theses

Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system leading to debilitating long-term neurologic damage, primarily due to the limited ability of remyelination in the adult human brain. This review summarizes the current knowledge regarding the combined administration of Cuprizone (CPZ) and rapamycin as a novel animal model for MS. Utilization of CPZ induces non-immune mediated demyelination, therefore bypassing complexities of the immune system and allowing analysis of de-/remyelination. Furthermore, remyelination occurs simultaneous with demyelination due to ongoing oligodendrocyte progenitor cells (OPCs) differentiation into mature oligodendrocytes (OLGs).

The immunosuppressive agent, rapamycin inhibits the regulatory pathway Akt/mTOR, …


Diabetes And Physical Activity, Jameela Banu Jan 2016

Diabetes And Physical Activity, Jameela Banu

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Diabetes has been on the rise globally. Although many factors contribute to the increasing risk and manifestation of this disease lack and decreased physical activity/ exercise stands out as one of the major factors. Treatment interventions for prediabetic and diabetic patients include diet and lifestyle changes with enhanced physical activity/ exercise. Several types of physical activity are available for these patients but, recommendations have to be made on an individual basis after giving due consideration to the comorbidities and other risks and barriers. Implementation of progressive resistance therapy may be successful in maintaining glucose homeostasis in diabetic patients.

Gras-Fed Americans: Sick Of Lax Regulation Of Food Additives, Martha Dragich Jan 2016

Gras-Fed Americans: Sick Of Lax Regulation Of Food Additives, Martha Dragich

Faculty Publications

Americans are “GRAS-fed” because of a “loophole” in the strict regime Congress provided for the regulation of food additives. Additives - and food products containing them - are exempt from this strict regime if they are accorded GRAS (Generally Recognized as Safe) status. The guidelines Congress provided for achieving that status by scientific evidence of safety are no longer observed. Most additives are determined by the producer alone to be GRAS. At the same time, Americans’ consumption of highly processed foods continues to rise, giving rise to long-term health problems that are increasingly tied to diet. The average American’s diet …


A Qualitative Pilot Study Of Aging Women’S Physical Activity Experiences In One University Fitness And Wellness Center, Alexis Hobbs Jan 2016

A Qualitative Pilot Study Of Aging Women’S Physical Activity Experiences In One University Fitness And Wellness Center, Alexis Hobbs

Online Theses and Dissertations

Physical inactivity is one of the driving risk factors for developing health problems such as obesity, diabetes, and cardiovascular diseases (World Health Organization, 2003). The prevalence of these diseases increases with the aging process, which renders participation in physical activity crucial among the aging population. There is strong evidence that physical activity reduces the risk of these health disparities and disabilities (Young & Dinan, 2005), however despite these well-documented benefits, aging women still remain sedentary. This study examined the phenomenon of women 55 years of age or older and their lived experiences of participating in physical activity within a university …


An Unprecedented Research Project Into The Alcohol Retention Variation Of Flavored Spirits, Armanda Fae Mcfadden Jan 2016

An Unprecedented Research Project Into The Alcohol Retention Variation Of Flavored Spirits, Armanda Fae Mcfadden

Online Theses and Dissertations

Accurate determination of alcohol by volume (ABV) is necessary, but previously used techniques are proving inaccurate with new flavored spirits. Specifically, control experiments showed that increasing concentrations of sugar led to increasingly inaccurate ABV determination. We hypothesize the intermolecular forces present in these beverages are significantly altered by the presence of sugar, which in turn leads to the observed inaccuracies in ABV measured through distillation. We used additives such as NaCl and NaOH to strategically and systematically vary intermolecular interactions and the influences of these additives on ABV were tested through distillation, densitometry, and nuclear magnetic resonance spectroscopy (NMR). Given …

Turkish Journal of Veterinary & Animal Sciences

The effects of in ovo administration of β-hydroxy-β-methylbutyrate (HMB) on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative (no injection) and positive (physiologic serum injection) controls and three HMB treatment groups. HMB solution was injected at 0.1% (Group 1), 0.2% (Group 2), and 0.3% (Group 3) concentrations. There were no significant differences between the groups for live weight gain, feed conversion rate, and hot carcass, breast meat, liver, and heart weight. However, the gizzard weight in Group 1 was significantly higher than those in the other groups (P < 0.05). Although the intestinal villi lengths in the treatment Groups 1 and 3 on day 20 were greater than those in the control groups (P < 0.01), at the end of the experiment there were no significant differences among the groups. For antibody levels, the differences between groups on days 4 and 42 were highly significant (P < 0.01), and the antibody levels in Group 2 were higher than those in the other groups. Separately, growth performance and antibody levels were positively correlated with the length of villi in Group 2 (HMB 0.2%).
