Mycobacterium-Plant Interactions In Bioremediation Of Polycyclic Aromatic Hydrocarbon Compounds, Robert D. Child

Biology

Five mycobacterium isolates that degrade polycyclic aromatic hydrocarbons colonize the surface of barley roots from a seed inoculum. Colonization was maintained in the presence of an aggressive root-colonizing pseudomonad. All five of the mycobacterium strains utilized components in root washes for growth but they differed in their potential for biofilm formation. Components in the barley root washes did not impede the mineralization of pyrene. An inexpensive, portable, flexible microcosm chamber system was constructed and implemented in pyrene mineralization experiments. The system facilitated control of sterile conditions, air flow-through, and collection of volatilized radiolabeled compounds. Mineralization rates of pyrene were higher …

Catalase Activity Mediates The Inhibitory Actions Of 24,25 Dihydroxyvitamin D3, Sven L. Peery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The steroid hormone 1,25-dihydroxyvitamin D₃ [1,25(OH)₂D₃] rapidly stimulates the uptake of phosphate in isolated chick intestinal cells, while the steroid 24,25-dihydroxyvitamin D₃ [24,25(OH)₂D₃] inhibits the rapid stimulation by 1,25(OH)₂D₃. Earlier work in this laboratory has indicated that a cellular binding protein for the 24,25(OH)₂D₃ is the enzyme catalase. Since binding resulted in decreased catalase activity and increased H₂O₂ production, studies were undertaken to determine if pro-oxidant conditions mimicked the inhibitory actions of 24,25(OH)₂D₃, and anti-oxidant conditions …

Electroporation Of Pediococcus Pentosaceus And The Curing Rate Of Plasmids, Heidi E. Shields

Undergraduate Honors Capstone Projects

Genetic engineering is a relatively new process and is a major focus of research in various fields, such as medicine, plant genetics, and food science. The potential applications of genetic engineering include designer drug production, mass protein production, and enhanced food processing. Finding an appropriate host organism to be used in genetic engineering is an important preliminary step. Pediococcus pentosaceus has been suggested as a bacterial species with such potential. Since plasmids are often the vector of choice in genetic recombination, this research tests the ability of P. pentosaceus to take up and incorporate plasmids into its genome. Two plasmids …

Milk Intake In Early And Late Adulthood And Risk Of Osteoporotic Hip Fractures In Utah, Melanie Jean Slavens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between milk intake and risk of osteoporotic fractures is uncertain. Associations between milk intake and milk avoidance in relation to osteoporotic hip fracture were examined in the Utah Study of Nutrition and Bone Health (USNBH), a statewide case-control study. Cases were ascertained at Utah hospitals treating 98 percent of hip fractures during 1997-2001 and included 1188 men and women aged 50-89 years. Age- and gender-matched controls were randomly selected from Utah driver's license and Medicare databases (N= 1324). In-person interviews were conducted and participants reported frequency of milk intake per week at age 18 and during pregnancy among …

Dysphagia And Nutrition In The Elderly, Amanda Panting

Undergraduate Honors Capstone Projects

Dysphagia and nutrition in the elderly go hand in hand. As age increases, bodily functions decrease. The loss of function causes an increased susceptibility to swallowing disorders and possible malnutrition. Dysphagia in the elderly increases mortality and morbidity rates (3). This paper discusses causes, symptoms and consequences of dysphagia. Swallow studies and various feeding techniques are examined. Alzheimer's disease, dementia and stroke are diseases that are commonly seen among patients with dysphagia (3, 10). Alternative nutrition via enteral feeding has been shown to increase survival rate (14, 15, 16). The ethics of prolonging death or prolonging life through nutrition support …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examined the lifetime exposure of women's employment on cognitive functioning and cognitive decline in late life.

From the Cache County Study on Memory, Health, & Aging data, a sample of 2,588 women, aged 65 and older gave retrospective occupational history and were screened using the Modified Mini-Mental State Exam at study entry and approximately 3 years later. Non-demented women were used.

Ordinary least squares regression was used cross-sectionally and longitudinally to test the association between cognitive complexity level of the longest job and baseline cognitive status, and rate of cognitive decline over approximately 3 years.

Cross-sectional analysis revealed …

Prevalence Of Type 2 Diabetes In Youth And Adolescents, Julie Patterson

Undergraduate Honors Capstone Projects

Until recently, Type 2 diabetes was typically regarded as a disease of the middle-aged and elderly. While it is still true that this age group maintains a higher risk than younger adults, evidence is accumulating that onset in those of a much younger age. Children and adolescents are now part of this epidemic. This new phenomenon brings a serious new aspect to the global diabetes epidemic and heralds an emerging public health problem of major proportions. Prevention and treatment in these youth cannot be taken lightly. Prevention can be maintained through implementing exercise and balanced nutrition. It is essential to …

Food Insecurity And Hunger In America, Elizabeth Zufelt

Undergraduate Honors Capstone Projects

Studies have shown that about twelve percent (13.5 million) of American households experience at least some form of food insecurity in one year. Causes for food insecurity include disability, low income if employed, unemployment within the past six months, and retirement. Hunger and obesity are often seen in the same person at the same time, including children. The effects of hunger and food insecurity seen among children include: anemia, higher levels of anxiety, poorer performance on mathematical tests, depression, aggression, tardiness, a poorer sense of well-being, lower physical abilities, and lower psychosocial abilities. Food insecurity also affects the elderly population. …

Dietary Supplement Use Among The Elderly, Diana Kristine Keith

Undergraduate Honors Capstone Projects

Introduction: According to NHANES data from 1999-2000, 52% of US adults reported talcing a dietary supplement in the last month. Even greater use of dietary supplements is observed among older individuals. Dietary supplements contain a wide range of ingredients from vitamin and minerals (VM) to botanicals, herbs, amino acids, and other ingredients sometimes referred to as non-vitamin and minerals (NVM).

Methods: Data on VM and NVM supplement use was collected in a prospective study of elderly people living in Cache Valley, Utah. The reported supplements were researched to obtain ingredient information and then categorized into groups representing the types of …

An Analysis Of Nutritional Services Available For Persons With Developmental Disabilities, Dawnie Elzinga

Undergraduate Honors Capstone Projects

Developmental disabled (DD) individuals are living longer, more normal lives in the United States. There has been an influx of DD individuals living in residential settings instead of the more traditional institutional setting. Consequently, dietetic professionals will encounter persons with DD in every area of practice. Nutrition therapy is becoming more important in the multidisciplinary treatment of DD individuals. Governmental legislation and community programs have improved the treatment and rights of DD persons over the past decade. Even with these advocacy efforts, DD persons are often not receiving the nutritional treatment they need. Common nutritional problems encountered in the DD …

Nutrition In Traumatic Brain Injuries, Jaylene Dalley

Undergraduate Honors Capstone Projects

Nutrition intervention and support is a critical part of caring for traumatic brain injury (TBI) patients. TBI patients have high energy and protein needs, as well as increased needs for some vitamins and minerals. There are a number of ways to assess energy and protein needs for TBI patients including indirect calorimetry, the Harrris-Benedict Equations and the Glasgow Coma Scale Equation. Most TBI patients are either non-responsive (comatose) or develop some form of dysphagia and, therefore, are unable to consume adequate amounts of nutrition via the oral route. Nutrition support through enteral or parenteral routes may improve the medical outcome …

Influence Of Soil Compaction On Nitrogen Volatilization In A Management Intensive Grazing System: Estimation Of Gaseous N Losses Using Mass Balance In Intact Soil Cores, Luke Alan Petersen

Undergraduate Honors Capstone Projects

Increasing concern about the environmental impacts of greenhouse gases and PM 2.5 particulates has prompted many researchers to examine the processes of gaseous loss of nitrogen (N) from agricultural land. As agricultural production becomes more competitive and producers strive to become more efficient by reducing input costs, they will increasingly employ practices such as the rotational stocking, also called Management Intensive Grazing (MIG). MIG utilizes high animal stocking rates for short periods of time to efficiently harvest pasture crops. Unfortunately, MIG also produces relatively high concentrations of livestock excreta. This has caused intensive grazing practices to become a focal point …

Cystic Fibrosis And Nutrition Risk, Kristen Rae Stokes

Undergraduate Honors Capstone Projects

Introduction: Cystic Fibrosis (CF) is an autosomal recessive disorder with serious pulmonary and nutritional implications. Nutrition status has a direct affect on lung function and longevity. Screening patients for growth velocity makes it possible to identify patients at nutritional risk. This identification is the first step towards appropriate nutritional interventions. The current screening tool used for children and adolescents with CF is not reliable and leaves too much room for clinical judgment. It is for this reason that a new screening tool was developed. Methods: The Cystic Fibrosis Foundation established a panel of experts for the purpose of developing an …

Government Food Assistance Programs: A Nutritional Perspective, Marlee Harris

Undergraduate Honors Capstone Projects

Food security remains a problem in the United States. Historically, the government began to distribute excess agricultural goods to those in nutritional need. Efforts to provide food to people in need continue today through the Food Stamp Program (FSP) and the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Nutrition status of participants in these programs demonstrates the nutritional effectiveness of these programs. These programs provide needed benefits and are making positive changes in food security, but improvements can be made to fully improve the nutrition status of these low-income participants. Nutrition professionals can be key in improving …

The National School Lunch Program: History Of The Past, Challenges Of The Present, Solutions For The Future, Hilary Annie Smith

Undergraduate Honors Capstone Projects

The National School Lunch Program (NSLP) was initially designed to provide nutritious meals to hungry schoolchildren. Over time, it seems as though this focus has shifted to serving as a source of proper nutrition in a society of over-fed yet undernourished children. The stated purpose of the NSLP is to "safeguard the health and well-being of the nation's children and to encourage the domestic consumption of nutritious agricultural commodities and other food." Currently, there are many challenges that the National School Lunch Program faces in meeting its goal of promoting healthful lifestyle practices among school-aged children. Three main challenges include …

Motivation And The Dietitian: Dietitians Must Increase Their Efforts To Motivate And Bring About Long-Term Success In Their Clients, Cory Ann Hansen

Undergraduate Honors Capstone Projects

Perhaps the most difficult aspect of a dietitian's job is motivating clients to make necessary changes in their lives to benefit their health. Although most people are capable of enduring short-term attempts at healthy living, a lifetime of appropriate dietary habits is difficult for virtually everyone. One of the greatest challenges of long-term success is a lack of motivation. This signifies that it is not skills or knowledge that people lack in general. Therefore, dietitians must focus part of their efforts on motivation rather than simply teaching people what they need to do. Methods that have been found to be …

Nutritional Concerns In Pediatric Renal Disease, Rachael Firmage

Undergraduate Honors Capstone Projects

Chronic kidney disease is a growing area of nutritional concern as the number of diagnosed cases increases. Children suffering from these renal diseases require special attention and medical nutrition therapy because of concerns and problems unique to this renal population. Uncontrolled kidney failure in pediatric patients can result in a number of consequences, such as growth retardation, anemia, metabolic imbalances, renal osteodystrophy, anorexia, and malnutrition. With the proper guidance, medical interventions, and dietary prescriptions, these untimely side effects can be reduced or avoided all together.

Health Promoting Aspects Of The Mediterranean Diet, Devrie Fielding

Undergraduate Honors Capstone Projects

In the 1960's information regarding the diet of the Mediterranean Regions was publicized as a healthful way of eating. Information was obtained from the Seven Countries Study conducted by Ancel Keys. This study revealed that residents of these regions had a lower incidence of coronary heart disease and increased longevity. Such health benefits were connected with low intakes of saturated fat. However, several other studies since then have found the Mediterranean dietary patterns to be more than cardioprotective. A decreased risk of cancer, reduced morbidity and mortality, and a decreased risk of several other diseases are also attributed to the …

Diet And Nutritional Concerns Of Hispanic Americans, Valerie Rawlinson

Undergraduate Honors Capstone Projects

Hispanic Americans are the second largest ethnic minority group in the United States today, at 12.5% of the total U.S. population. They face considerable nutrition-related challenges, of which dietitians and other nutrition professionals who serve this population need to be aware. Their diet goes through drastic, rapid changes soon after immigration to the United States, many of which have a strong negative impact on their health, putting them at greater risk for obesity and chronic diseases than the general population. In addition to diet and disease, Hispanic Americans face other issues that hinder their ability to benefit from nutritional counseling, …

Refeeding Practices Of Malnourished Children, Marcianne Wittwer

Undergraduate Honors Capstone Projects

Over 200 million children in developing countries under the age of five are malnourished. Malnutrition contributes to more than half of the nearly 12 million under-five deaths in developing countries each year. The World Health Organization (WHO) defines malnutrition as "the cellular imbalance between the supply of nutrients and energy and the body's demand for them to ensure growth, maintenance, and specific functions." Because of the high demand for energy and essential nutrients, infants and children are at a particular risk for under-nutrition. Malnutrition is a condition that needs to be taken seriously and with proper treatment can save the …

Body Image Among Elementary-Aged Children: Development, Implications, And Interventions, Mindy Beth Probst

Undergraduate Honors Capstone Projects

Body image is the mental image or conception that one has of one's body. Its development is effected by an individual's life experiences beginning at birth. Statistics show that close to half of elementary-aged children are already dissatisfied with their bodies and have begun to develop negative body images. Review of the current literature suggests that family, peers, cultural values and the media, and changes in physical appearance related to adiposity rebound and puberty are the major causes of this unfortunate situation. Research is also showing that children are participating in unhealthy diet and exercise practices as a result of …

The National School Lunch Program, Elizabeth Strasser

Undergraduate Honors Capstone Projects

The National School Lunch (NSLP) Program is a federally assisted meal program that began in 1946 and is designed to provide nutritionally balanced lunches to children. The program started slowly in 1853, in a few school districts around the United States. The efforts spread throughout different cities, and organizations were set in place to serve meals to children in schools under the supervision of the school boards.

The American Dietetic Association believes that all children and adolescents should have access to food and nutrition programs that ensure adequate food supply that promotes optimal physical. and social growth and development.

Nutritional Perspective Of Systemic Lupus Erythematosus, Jessianna Rose

Undergraduate Honors Capstone Projects

Systemic Lupus Erythematosus (SLE) is a chronic, incurable, autoimmune disease that affects as many as two million persons in the United States. Current nutritional guidelines are very basic and revolve around specifics of the treatment of symptoms as seen with drug-nutrient interactions. Although current opinion does not directly see the onset of this disease linked to dietary factors, recent research may indicate that there is a link to a possible deficiency of pantothenic acid. This is not a widely accepted theory, but has some very unique observations which shed a new and interesting light on possible interventions through nutrition.

This landslide did considerable damage to the Logan and Northern canal, which is cut into the slope, and to a residence at the toe of the slope. This event brought many parties together to collaborate on possible solutions to the immediate fix of the slide as well slides that could occur in the future. The purpose of this report is to compile information useful to the study of the area and the possible solutions and/or risk assessment of the Logan Bluff Landslide …

The Integration Of The Nutrition Screening Tool With The Interdisciplinary Plan Of Care Form, Beth Hyatt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Literature Review

Undernutrition in the hospital setting has been shown to cause adverse outcomes. Screening for nutritional risk assists in the detection of undernutrition with subsequent early intervention to prevent further decline. While many nutrition screening tools exist, none are proven to detect undernutrition. Furthermore, many barriers exist for utilizing nurses as primarily responsible for screening patients for nutritional risk.

Background

A hospital reviewed the nutrition screening process and found that the form used and screening factors were insufficient to adequately detect undernutrition and appropriate referrals for dietitians.

Objectives

1) Determine if nursing compliance improved when the nutrition screening form …

Antimicrobial Properties Of Syringopeptin 25a And Rhamnolipids, Prerak T. Desai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increasing bacterial resistance to available antibiotics requires the search for new antibacterial compounds to be broadened. This study investigated the antimicrobial properties of two secondary metabolites from fluorescent pseudomonads -- syringopeptin 25A, a lipodepsipeptide produced by Pseudomonas syringae pv. syringae, and a rhamnolipid mixture produced by Pseudomonas aeruginosa. The rate of antimicrobial action was determined by monitoring the rate of uptake of propidium iodide during exposure to the compounds. Inhibition was also confirmed by the microbroth dilution method to determine the MI Cs. Both the compounds inhibited growth of Gram-positive organisms, including Mycobacterium smegmatis, staphylococci, and …

Use Of Natural Antioxidants To Control Oxidative Rancidity In Cooked Meats, Mihir Vasavada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The research in this dissertation focused on determining antioxidant effects of various natural antioxidants in cooked meat systems. Milk mineral (MM), spices, and raisin paste were used in cooked meat systems to verify their potential antioxidant properties.

The MM study determined the antioxidant activity of 1.5% MM added to uncured cooked beef meatballs, and possible additive effects of MM in combination with 20-ppm or 40-ppm sodium nitrate in cooked beef sausages. There was no additive inhibition of lipid oxidation in samples containing 20-ppm or 40-ppm sodium nitrite plus 1.5% MM. Cooked meat yield was not different between control meatballs and …

Type 2 Diabetes And The Risk Of Osteoporotic Hip Fracture In Utah Men And Women, Megan Bunch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prior studies have unequivocally established a consistent association between osteoporotic hip fracture risk and type 2 diabetes mellitus. One reason this association still remains unclear is primarily due to the limited amount of research conducted in this area. The Utah Study of Nutrition and Bone Health (USNBH) is a case-control study conducted in Utah during the period of 1997-2001 to determine risk factors for osteoporotic hip fracture. All study participants (n = 2590) were determined from Utah residents 50-90 years of age. Cases were determined from 18 Utah hospitals during 1997-2001. Age and gender-matched controls were randomly selected from the …
