Spray Drying Technology For The Production And Processing Of Microencapsulated Omega-3 Fish Oil With Egg Powder, Kevin Estuardo Mis Solval

LSU Master's Theses

Protein with essential amino acids is required for recovering, repairing, and building muscles after intensive exercise. A powder produced with egg white (EW) (high quality protein) and fish oil (menhaden (Brevoortia patronus) (MO) oil or salmon oil (SO)) with high DHA and EPA content should be particularly beneficial for athletes. The objective of this study was to develop microencapsulated omega-3 fatty acids fortified EW powders. Two stable emulsions were prepared with 3.43% (MO) or (SO), 56.21% EW, and 40.36% water (E-MO-EW and E-SO-EW). An EW with water solution (without fish oil) (E-EW) was prepared as a control. Two emulsions (E-MO-EW; …

Pharmacological And Non-Pharmacological Approaches To Prevent Hypertension-Induced Renal Disease In The Spontaneously Hypertensive Rate, Carrie Marie Elks

LSU Doctoral Dissertations

Hypertension affects 50 million Americans and remains the second leading cause of renal failure in the United States. Current pharmacological and non-pharmacological approaches to treat hypertension have proven effective, but the complexities of the disease and its renal effects warrant the need for new treatments. The hypothesis of this dissertation was that pharmacological or non-pharmacological approaches to reducing inflammation and oxidative stress would prevent hypertension-induced renal injury in the spontaneously hypertensive rat (SHR). In the first study, we blocked the inflammatory transcription factor, nuclear factor-kappa B (NF-ĸB), with pyrrolidine dithiocarbamate in the SHR kidney. In treated SHR, blood pressure decreased, …

Changes In Select Phenolic Compounds During Ethanol Fermentation And Acetification Of Raspberry, Blueberry And Persimmon, Yen-Ping Tan

LSU Master's Theses

Polyphenols are major dietary components in fruits and vegetables. Many research and epidemiological studies have reported that phenolic compounds, such as anthocyanins, may have a protective effect against various degenerative diseases. Phenolics in grape wine have been extensively studied but information on changes of phenolics in wine and vinegar made from other fruit crops is limited, however. This research started with the objective of determining the effect of proteases in preventing phenolic and, specifically, anthocyanin degradation in the ethanolic fermentation of black raspberries to reduce sugar content. The results of this study led to investigations of changes of other polyphenols …

LSU Master's Theses

The objective of these studies was to determine the association between dietary intakes of selected food groups, macronutrients, and micronutrients in mother-child dyads. This was a secondary analysis of data on low-income Black, Hispanic, and White children 3-5 years-old (y) participating in Head Start (HS) (n=650), and their mothers. Mothers served as a proxy for their child, and self-reported intake during a multiple-pass 24-hour recall interview for one weekend day. One weekend day was chosen since children attended HS during the week, and mothers may not know what their children consumed outside the home. Data were collected on children’s and …

Building Children's Liking And Preferences For Fruits And Vegetables Through School-Based Interventions, Anantha Padmaja Lakkakula

LSU Doctoral Dissertations

Children’s food preferences play a major role in their food choices and consumption. The objectives of these studies were to examine the relationship between children’s preferences for fruits and vegetables (FV) and their weight status and to increase children’s liking of FV by offering repeated opportunities to taste less liked items. A representative sample of elementary school children (1st, 3rd, 4th, and 5th grades) were recruited in the three interventions. In the first study, 341 fourth- and fifth-grade children (43% boys; 68% 4th graders) were measured for height and weight and completed a survey which sought their preferences for 38 …

Resistant Starch In The Diet Of Rodents Promotes An Increase In Fermentation And A Reduction In Body Fat In An Animal Model Of Dietary Obesity, Jason Andrew Charrier

LSU Master's Theses

In previous studies, in has been observed that the addition of resistant starch (RS) in the diet of rodents, a non-digestible fermentable fiber, promotes increases in markers of fermentation and improvements in body weight and body fat analysis when incorporated into low to moderate fat diets. This study investigated whether the same beneficial effects observed with RS addition in these lower fat diets could be obtained in a high fat diet, and if the type of fatty acid consumed in the diet makes a difference in markers of fermentation and body fat. Sprague Dawley rats (n=96) were fed as weight …

Optimization Of Adult Multipotent Stromal Cell-Bioscaffold Interactions For Tissue Regeneration With Bioreactors, Lin Xie

LSU Doctoral Dissertations

Adult multipotent stromal cells (MSCs) in combination with biocompatible scaffolds may augment well-established medical and surgical techniques. Pre-implantation cell loading and viability on scaffold carriers followed by in vitro differentiation and extracellular matrix (ECM) formation contribute to the efficacy of in vivo tissue formation. Given the specificity of the parameters for each cell-scaffold construct, it is vital to assess the relative potential of various combinations to select the best option for various clinical needs. High demand for equine and human bone regeneration especially non-union fracture repair is still largely unaddressed. Therefore osteogenesis potential of both equine and human MSCs engrafted …

Sensory Discrimination Testing With Children, Karen Melissa Garcia

LSU Doctoral Dissertations

Literature concerning children’s performance in sensory discrimination methods is not as extensively published as performance with adults. Therefore, in this dissertation children’s performance in discrimination methods was investigated. First, performance in the triangle and 3-AFC methods was explored with children 6 to 12 years old. The paradox of discriminatory non-discriminators states that the proportion of correct responses in the 3-AFC method will be higher than that of the triangle. However, Thurstonian theory predicts that despite the difference in proportions of correct responses the degree of difference between the stimuli will be similar. The paradox and the Thurstonian predictions were challenged …

Comorbid Psychopathology In Children With Autism Spectrum Disorders - Cut-Off Scores For The Autism Specturm Disorders-Comorbidity For Children (Asd-Cc), Ryan Thomas Thorson

LSU Doctoral Dissertations

Once considered rare, Autism Spectrum Disorders (ASD) are increasingly becoming viewed as common disorders. Prevalence rates of ASD have increased drastically in recent years. Recent studies suggest comorbid psychopathology within ASD to be more common than previously thought. Though these deficits exist, specific instruments to diagnose psychopathology in this population do not yet exist. This highlights the underlying need for instruments to identify psychopathology in individuals with ASD. The aim of this study was to establish cut-off scores for the Autism Spectrum Disorder – Comorbidity for Children, an instrument designed to assess for comorbid psychopathology within individuals with ASD.

Water and an 18% crude protein calf starter were offered ad libitum beginning d 3 throughout the duration of the 56 d trial. Calves remained in their hutches until d 56 of age …

Characterization Of Spiroplasma Mirum And Its Role In Transmissible Spongiform Encephalopathies, Hilari Maree French

LSU Doctoral Dissertations

There are many contradictory reports in the literature involving the culture of Spiroplasma mirum, its resistance to disinfectants and antibiotics, and its potential role in Transmissible Spongiform Encephalopathies (TSEs). These contradictions led to an interest in a possible link between spiroplasma and TSEs and the development of a research plan to elucidate this connection. It was hypothesized that Spiroplasma was associated with a neurodegenerative disease such as TSE. In this work we further characterized S. mirum laboratory strains and continued to evaluate the possible correlations they have with TSE infections and the prion. To optimize recovery of S. mirum from …

Purification Of Fish Oils And Production Of Protein Powders With Epa And Dha Enriched Fish Oils, Huaixia Yin

LSU Doctoral Dissertations

Eicosapentaenoic (EPA) and docosahexaenoic (DHA) in marine oils are known to provide health benefits. However, marine oils are accompanied by saturated fatty acids. By enriching fish oils with EPA and DHA the beneficial effect of fish oils can be increased while limiting the detrimental effect of the saturated fatty acids. Fish oils need to be purified before consumption. A number of methods have been used for extracting and purifying EPA and DHA enriched fish oils; however, thermal degradation and oxidation of polyunsaturated fatty acids (PUFAs) often occurs as a result of exposure to high temperatures, solvents and adverse conditions during …

A literature review was conducted to identify the challenges associated with the assessment and treatment of eating disorders and post-traumatic stress disorder. The literature supports the need for occupation-based interventions, especially in the areas of self-care, meal planning and preparation, sleep and rest, leisure, and various life skills. Guided by the Model of Human Occupation in conjunction with cognitive behavioral therapy techniques, an occupation-based program guide was developed. The …

Children With Gastroesophageal Reflux Disease: A Guide To Therapeutic And Pharmacological Treatments, Rebecca Mcomie

Occupational Therapy Capstones

Gastroesophageal reflux disease (GERD) is becoming a more common diagnosis with young children and babies (PAGER, 2010). GERD is often misdiagnosed and there is no single test available to determine its presence (Eisen, 2001). The term reflux can be confusing and used to mean different things to different people. Often reflux is linked to colic in babies or may be considered a "normal" part of being a baby. But when a sequalae of symptoms arise in an infant, gastroesophageal reflux becomes a serious issue that needs to be addressed through a variety of interventions and sources (Sondheimer, 2006 ).

Pavlovian Conditioning Between Cocaine Stimulant Effects And A Discrete Sensory Cue: Implementation Of An Alternating Conditioning Procedure, Jonathan Miller Wachtel

Honors Papers

Cocaine addiction is associated with an extremely high rate of relapse, the resumption of drug taking behavior following a period of abstinence. Relapse may be induced by exposure to drug-associated cues, stress, or drug challenge. Rodent models of addiction investigate reinstatement, the resumption of drug-seeking behavior following a period of abstinence. This study investigated the necessary procedures for establishing Pavlovian conditioning between a discrete sensory cue and cocaine stimulant effects (15.0 mg/kg, IP). Successful conditioning was indicated by cue induced conditioned hyperactivity. In Experiment 1, a simple discrete visual cue failed to be attributed salience. Cocaine-treated rats showed heightened locomotor …

Disease, Medicine And Health, Diego Armus, A. López Denis

History Faculty Works

This article focuses on three overlapping trends in the historical study of human responses to illness, labeled as “new history of medicine, history of public health, and sociocultural history of disease.” The topics range from colonial epidemiology and pharmacopoeia to twentieth-century public health institutions and urban hygiene. But a consistent focus on the social, cultural, and symbolic components of diseases and cures unifies this historiography and distinguishes it from the narrower scope of the long-established field of the history of medicine.

Improving Community Participation Of The Inactive Elderly: Preferred Learning Style-Based Interventions, Catherine Bailey

Occupational Therapy Capstones

Occupational therapists believe social engagement is vital to the health and well-being of the older adult. Social isolation has been linked to loss of physical, cognitive and emotional health. Elders at risk of social isolation are not specifically addressed by community health programs due to lack of knowledge and resources. Social isolation and loss of meaningful activity are significant precursors to rapid decline in the health and well-being of elderly people living in their communities.

Literature indicates that use of personal learning style preferences to problem solve improves success in occupation. Older adults often lack awareness of their personal learning …

Strategies To Promote Oral Motor Skills And Progression Of Foods For Infants And Young Children With Feeding Concerns, Heather Davis, Anne Winter

Occupational Therapy Capstones

Eating is a primary occupation for individuals from birth through adulthood. However, some infants and young children experience difficulty and frustration as they begin to eat and transition to foods with texture. Field, Garland, and Williams (2003) determined that up to 80% of children with developmental disabilities experienced problems with feeding. There is a need for providing education and support for the families of these children (White-Traut & Norr, 2009). Pilkington (2006) conveyed that supporting and building the parent's capacity for caring for their child resulted in enhanced outcomes for the infant or child. Current resources may not be parent-friendly …

The Advance Directive Registry Or Lockbox: A Model Proposal And Call To Legislative Action, Joseph Karl Grant

Journal Publications

In times of need, what portal or place could we go to easily to retrieve a person's advance directives when we have need to employ and use them? A handful of states have come up with a solution. Nevada, Washington, and Vermont now have legislation in place that allow citizens of those states to electronically store their advance directives on the internet -in an electronic lockbox or portal of sorts. These states have addressed a critical need of their citizens: the need to have their advance directives accessible and readily available to health care providers so that their intent and …
