Should Physical Activity Be Included In Nutrition Education? A Comparison Of Nutrition Outcomes With And Without In-Class Activities, Debra M. Palmer-Keenan, Kirsten Corda

Journal of Extension

Limited-resource adults' dietary intakes and nutrition behaviors improve as a result of Expanded Food and Nutrition Education Program (EFNEP)/Supplemental Nutrition Assistance Program Education (SNAP-Ed) participation; however, physical activity education is needed for improved health. The experimental study reported here assessed if spending time doing physical activity education affected dietary impact results and activity among participants. Standard dietary assessments showed no significant differences between groups, and interviews showed greater physical activity improvements/intentions by the experimental group, which suggests that nutrition education can be shortened 15-20 minutes for physical activity demonstrations to improve activity behaviors without adversely affecting nutrition-related behavioral improvements outcomes.

Osteoblast Oncostatin M Signaling In Modeled Spaceflight, Jacob Goyden

Boise State University Theses and Dissertations

Bone deterioration is a challenge in long-term spaceflight with significant connections to terrestrial disuse bone loss. Prolonged unloading and radiation exposure, defining characteristics of space travel, have both been associated with changes in inflammatory signaling via IL-6 class cytokines in bone. While there is also some evidence for perturbed IL-6 class signaling in spaceflight, there has been scant examination of the connections between free fall, radiation, and inflammatory stimuli in bone. Our lab and others have shown that the IL-6 class cytokine oncostatin M (OSM) is an important regulator of bone remodeling. We hypothesize that spaceflight alters osteoblast OSM signaling, …

New Beginnings: A Discussion Guide Adaptation For Living With Diabetes Among An Urban American Indian Community, Eudora Lynette Claw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diabetes is a chronic disease where the body has the inability to control the sugar levels in the blood to convert into to usable energy needed to fuel the body's cells. Some common diabetic complications include heart disease, stroke, amputations, and possibly blindness. It can be successfully managed with routine care of monitoring of sugar levels, eating a healthy diet, and daily exercise. The occurrence of type 2 diabetes is rising rapidly worldwide, but is a burden for AI/ANs (American Indian/Alaska Natives) at a substantially disproportionate rate. The purpose of this pilot study was to participate in a one-day curriculum …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to investigate lower extremity kinematics and muscle activation patterns in inclined backward walking (IBW) versus traditional backward walking (BW). This purpose was achieved by evaluating performance of individuals walking backward on a treadmill at inclines of 0%, 6%, 8%, 10%, and 12%. Eleven participants (24.9 ± 4.8 yrs, 71.9 ± 11.6 kg, 1.7 ± 0.09m) recruited from the UNLV student body went through a familiarization training program before any data were collected. The familiarization training, which took place across 3 different days, served to: 1) help the participants become comfortable and familiar with BW …

Development And Testing Of The Home Safety And Beautification Checklist With Mothers Referred For Child Neglect And Substance Abuse, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unintentional injury is the leading cause of death among children in the United States accounting for nearly 40 percent of deaths in this age group. Approximately 50 percent of nonfatal injuries, and 40 percent of fatalities, occur in and around the home. Elevated rates of child injury in the home environment are associated with parental substance abuse and neglectful behaviors. Childhood injuries are preventable, yet practical and cost-effective measures to identify child home safety risks are limited. This study involved a retrospective preliminary examination of the Home Safety and Beautification Checklist (HSBC) in a sample of drug-abusing mothers referred by …

The Wetsuit Effect: Physiological Response To Wearing A Wetsuit, Aaron Prado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Furthermore, the position (i.e., upright vs. prone) as well as the wetsuit size were explored as possible factors that influence the cardiovascular parameters. Twelve male participants (79.1±5.1 kg, 178.4±2.9 cm, 33.3±12.1 years) granted written consent and were assigned two wetsuits based on height, weight, and corresponding manufacturer recommendations. SWS signified the smallest possible wetsuit the subject could fit into according to recommendations, LWS signified the largest wetsuit the subject could …

The Impact Of Managerial Styles And Job Satisfaction On Employee Turnover In The Hospitality Industry, Amanda Ayres

UNLV Theses, Dissertations, Professional Papers, and Capstones

The hospitality industry in Las Vegas is a business that relies heavily on the competences of their employees. Unique to this industry, is the delivery of experiences rather than actual products or tangible goods. Due to the nature of this business, management styles, employee retention and standards of the employees are of the utmost importance to employers (Faldetta, Fasone and Provenzano, 2013). In summary, the stability among employees becomes an essential characteristic of the positive functionality of a hospitality organization. The irony in this is that high, employee turnover rates are common to these corporations. Employee turnover is a component …

Effects Of Lipopolysaccharide Induced Inflammatory Response On Early Embryo Survival In Ewes, Megan Renee Graham

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early pregnant ewes, 5 or 6 day post coitus (dpc) were used as a model to study early embryonic loss via gram-negative bacterial infections, such as mastitis. Ewes 5/6 dpc were injected with a gram-negative bacteria cell wall component, lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-&agr;), to induce an innate immune system acute phase response (APR). The induction of the APR and its reactant molecules, such as TNF-&agr; and acute phase proteins (APP), haptoglobin (Hp) and serum amyloid A (SAA), were initiated to study their effects on embryonic loss. In addition, ewes were also injected with LPS plus dexamethasone (Dex) …

West Virginia also faces health disparities and limited prenatal health resources, especially in at-risk areas. In an effort to improve resources in at-risk areas of the state, the "Health Education for Prenatal Providers in Appalachia (HEPPA), using the ACOG 5As smoking cessation intervention and breastfeeding promotion, was developed for delivery to interprofessional providers. Method: The HEPPA program delivered to healthcare and social service providers in four contiguous counties was evaluated by comparing pre-test …

The Effects Of Chronic Stress And Exercise On Mouse Pancreatic Islet Of Langerhans Morphology And Muscle Atrophy Gene Expression, Travis Parkulo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chronic stress has been implicated as a possible contributing factor to the onset of Type 2 Diabetes Mellitus through its negative effects on peripheral insulin sensitivity and the insulin producing beta cells of the pancreas. Exercise could serve as a possible countermeasure to the damaging effects of chronic stress due to its proven ability to increase insulin sensitivity at the level of the muscle and improve or maintain beta cell function and mass. To date, no published research has examined the effects of chronic stress in combination with voluntary wheel running on murine islet morphology and skeletal muscle atrophy. The …

Functional Characterization Of Phosphodiesterase-4a In Behavior And Obesity, Rolf T. Hansen Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cognitive disorders such as depression, anxiety, and senescent-induced memory loss are a growing pandemic in the world. Anxiety is the most common psychiatric disorder in America, affecting upwards of 50 million people a year; depression has a lifetime prevalence of 20% of the population, and it's predicted pathological memory disorders such as Alzheimer's disease (AD) will reach exponential levels by the year 2050. While there are treatments for anxiety and depression, far less success has been reached with therapeutics for AD. Phosphodiesterases (PDEs) may be a potential novel target for future therapeutics aimed at combatting these psychiatric illnesses and neurodegenerative …

Effects Of Dietary Immunomodulation On Parasite Load In Commercial Crossbred Lambs, Rebecca Christine Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multidrug resistant gastrointestinal nematodes have left sheep producers with little options to control the detrimental effects of parasitism on their flocks. Immunomodulation has been used in many autoimmune diseases in an effort to downregulate the immune system and alleviate pathology. However, upregulation of immune responses by use of dietary immunosaccharides may allow parasite susceptible sheep to clear a Haemonchus contortus infection. To test this hypothesis, Dorset-Texel lambs were fed a ration including CelmanaxRTM at 1g/hd/day for one week prior to receiving an experimental infection of 10,000 L3 stage H. contortus larvae; which continued until the completion of the study. Increases …

Functional And Genetic Analysis Of Choroid Plexus Development In Zebrafish, Hannah Elizabeth Henson

Theses and Dissertations (ETD)

The choroid plexus (CP) is an epithelial based structure localized within the brain ventricles and functions as the blood-cerebrospinal fluid barrier (BCSFB). Under normal conditions, the CP is responsible for generating the cerebrospinal fluid (CSF) and regulating its components. Abnormal CP function has been associated with neurodegenerative diseases, tumor formation in CP epithelia (CPe), and hydrocephalus. Despite the significant role of the CP in these disorders, little research has been done to characterize its functional properties and genetically dissect the pathways involved in normal CP development and disease. For this study, we have utilized zebrafish, (Danio rerio), as a model …

Probiotic Potential Of Bacterial Isolates From ‘Amabere Amaruranu’ Cultured Milk, Blaise B. Boyiri

Electronic Theses and Dissertations

Probiotics are viable nonpathogenic microbes that positively affect host health. Probiotics inhibit infection, activate immunity, and promote mucosal-barrier development. Many microbes have probiotic activity. Nonetheless, the selection of stable strains and their specific mechanism(s) of action are not fully elucidated. Bacteria from ‘Amabere amaruranu’ cultured milk from Kenya were isolated and identified by PCR sequence analysis of the 16S rRNA gene. Isolates were examined for stability to acid and bile, antimicrobial activity, mucin production, and degradation and sensitivity to antibiotics, hence their potential for probiotics. Lactobacillus isolates were acid unstable, bile-stable, nonmucinolytic, and presented antibacterial activity. L. rhamnosus cell fractions …

An Empirical Analysis Of The Role Of Geography In Sustainability Education, Makayla Jane Bonney

Theses

Many within and outside of the discipline of geography see it as a highly appropriate home for sustainability studies. Despite a history of human-environment education within geography and support from professional research or education organizations, some studies show that geography has not developed a lead role in sustainability education. This study examines the role of geography in offering "Sustainability Focused" courses as reported by AASHE STARS institutions with geography programs. The results show that although geography departments are highly utilized when available at an institution -offering the highest proportion of sustainability courses, averaging 14% of "Sustainability Focused" curriculum- there is …

Rorα Binds To E2f1 To Inhibit Cell Proliferation And Regulate Mammary Gland Branching Morphogenesis, Gaofeng Xiong, Ren Xu

Markey Cancer Center Faculty Publications

Retinoic acid receptor-related orphan nuclear receptor alpha (RORα) is a potent tumor suppressor that reduces cell proliferation and inhibits tumor growth. However, the molecular mechanism by which it inhibits cell proliferation remains unknown. We demonstrate a noncanonical nuclear receptor pathway in which RORα binds to E2F1 to inhibit cell cycle progression. We showed that RORα bound to the heptad repeat and marked box region of E2F1 and suppressed E2F1-regulated transcription in epithelial cells. Binding of RORα inhibited E2F1 acetylation and its DNA-binding activity by recruiting histone deacetylase 1 (HDAC1) to the protein complexes. Knockdown of HDAC1 or inhibition of HDAC …

Examining The Influence Of Farmers' Market Motivations On Access To Healthful Foods And Business Opportunities For Farms, Rachel K. Ward

Electronic Theses and Dissertations

Farmers’ markets are increasingly promoted as mechanisms for improving access to healthful foods for low-income households, as they are relatively inexpensive to establish and they can provide affordable food for low-income households by offering Supplemental Nutrition Assistance Program Electronic Benefit Transfer (SNAP/EBT). SNAP/EBT at markets also expands revenue opportunities for participating farmers. Market mangers provide a critical role in overseeing SNAP/EBT at markets and influencing business opportunities for farmers. Using a mixed-method approach, this study aimed to evaluate how managers’ motivations influence SNAP/EBT availability and participation at markets and business opportunities for small- and moderate- sized farms.

Characterizing Populations Of Non-Coding Rnas In Karenia Brevis At Different Times Of The Diel Cycle, Scott Boyd Anglin

Master's Theses

Karenia brevis is a mixotrophic, marine dinoflagellate found in the Gulf of Mexico that generates periodic, if not annual, harmful algal blooms (also known as “red tides”) in certain coastal areas. In an effort to better understand the biology of this organism, a functional genomics project has been initiated. As part of that project, it has been determined that a significant number of natural antisense transcripts (NATs) as well as double-stranded RNA (dsRNA) molecules exist within the transcriptome of K. brevis. I hypothesize that the non-coding NATs, similar to microRNAs (miRNAs) in other organisms play a role in regulating …

Predictors Of Major Commitment, Anna Jill Womack

Master's Theses

Contextual (e.g. job fit, job involvement), individual (e.g. job satisfaction, need for achievement), and demographic (e.g. gender, educational level) factors have been related to forms of career commitment (i.e. affective, continuance, and normative commitment), highlighting that the commitment one feels toward his or her career is a complex variable. Furthermore, commitment has been associated with intent to remain within a profession or organization (Bowling, Beehr, & Lepisto, 2006; Den Hartog & Belschak, 2007; Duffy, Dik, & Steger, 2011; Goulet & Singh, 2002), suggesting that commitment is an important component of retention within a career. Correspondingly, commitment to one's academic major …

Effects Of Selective Grazing By Microzooplankton On Phytoplankton Composition In A Subtropical Estuary, Amanda Marie Mcgehee

Master's Theses

Rates of phytoplankton growth and microzooplankton grazing were measured at two locations within the Bay of St. Louis, MS, over the course of three months to explore the dynamics of the phytoplankton community. Community growth rates were estimated based on the changes in chlorophyll a (chl a) concentration using the dilution technique, (Landry and Hassett, 1982) and a C-specific rate was obtained using chl a labeling (Redalje and Laws, 1981). Concentrations of chl a were determined using high performance liquid chromatography (HPLC) and fluorometry. HPLC was also employed to obtain class specific growth and grazing rates, using either marker pigments …

Role Of Msaa Gene In Regulation Of The Msaabcr Operon And Biofilm Development In Staphylococcus Aureus, Ahmed Alzuway

Master's Theses

Staphylococcus aureus is an important human pathogen that causes wide variety of diseases ranging from chronic biofilm associated infection to acute life threatening infection such as bacteremia, pneumonia, osteomyelitis, or endocarditis, despite the progress with antibiotics used in the treatment of bacterial infections. Furthermore, increased use of prosthetic and indwelling devices in modern medical practices has led to increased infections due to S. aureus. Treating S. aureus infections have become difficult owing to its ability to resist most of the antibiotics; this problem is further exacerbated by ability of MRSA strains to form biofilms. Emergence of community-acquired methicillin resistance …

The Effects Of The Nat Turner Slave Revolt On The Health And Welfare Of 19th-Century Slaves In Southeastern Virginia, Jeffrey Clifford Auerbach

Master's Theses

The Nat Turner Slave Revolt stands as a major turning point in the history of American slavery and represents a fundamental shift in the master slave relationship. This event shattered the previous paternalistic view and caused a fundamental reorganization of slave life. Included in this reorganization was a shift in the subsistence practice, moving away from morenutritious food grown by the slaves themselves to poor quality rations provided by the masters. This change in subsistence practices dealt a serious blow to the nutritional health of those living in the area surrounding the revolt.

By examining stature recorded in the County …

Mental Health Impairment And Human Capital Acquisition: Underage Drinking As A Predictor Of Concomitant Alcohol Dependence And Poor Educational Attainment, Euchay Ngozi Horsman

Dissertations

Underage drinking has featured prominently in both scholarly and conventional literature in recent decades as a major health and socio-economic concern in the United States. As new evidence emerges associating underage drinking with a host of negative outcomes for both the youth who drinks and society in general, a closer examination of the long-term effects of underage drinking is critical. This exploratory study was designed to examine predictor variables and their ramifications (1) using logistic regression to identify a model for underage drinking history (UDHISTORY) as a predictor of concomitant alcohol dependence and poor educational attainment (CADAPEA) among individuals aged …
