Examination Of Blueberry Anthocyanins In Prevention Of Age-Related Macular Degeneration Through Retinal Pigment Epithelial Cell Culture Study, Naomi Marie Sundalius

LSU Master's Theses

This research investigated the ability of blueberry anthocyanins to inhibit the uptake of N-retinyl-N-retinylidene ethanolamine (A2E) by retinal pigment epithelial (RPE) cells as quantified by pigment epithelial derived factor (PEDF) levels in RPE cells. The A2E was synthesized and identified by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Freeze dried blueberry powder of 50/50 blend (Tifblue/Rubel) anthocyanins were extracted by acetone and concentrated through chromatography. A RPE cell culture study investigating four treatments using a combination of 100 ìM A2E in DMSO and 100 ìg of blueberry anthocyanins in DMSO was tested. The treatments included: (A) control RPE cells; (B) RPE …

The Utilization Of Red Blood Cells In Diets For Swine And Poultry, Emily Dawn Frugé

LSU Master's Theses

The purpose of this research was to determine if increasing levels of RBC would affect growth performance and carcass characteristics of finishing pigs and growth performance of broilers. Three experiments were conducted to determine the effect of incremental levels of red blood cells (RBC; 0 to 4% and 0 to 2%), and thus increasing levels of dietary Leu on growth performance and linear carcass measurements of finishing pigs. Our results suggest that feeding 3 or 4% RBC causes a decrease in growth performance. However, feeding 1 or 2% RBC in the diets of finishing pigs had no detrimental effects on …

Succession Of Coleoptera On Freshly Killed Loblolly Pine (Pinus Taeda L.) And Southern Red Oak (Quercus Falcata Michaux) In Louisiana, Stephanie Gil

LSU Master's Theses

Wood is important in forest ecology because its large biomass serves as a nutritional substrate and habitat for many organisms, including Coleoptera, and beetles contribute greatly to nutrient recycling in forests. Overlapping complexes of beetles invade dead wood according to the species of tree, ambient conditions, and most importantly, stage of decomposition. Beetle succession was studied in loblolly pines (Pinus taeda L.) and southern red oaks (Quercus falcata Michx.) by documenting beetle arrival and residency in cut, reassembled, and standing bolts. Twelve trees of each species at Feliciana Preserve in West Feliciana parish, LA were felled during October 2004 and …

Feed Comparison For Dietary Standardization Of The Sea Urchin Lytechinus Variegatus And Assessment Of Parental Dietary Copper Toxicity By Fertilization And Embryological Tests, Heath W. Garris

All ETDs from UAB

Toxicity tests monitoring the effects of anthropogenic substances on marine systems are considered an important part of environmental management. Sea urchin fertilization and embryological toxicity tests are successful in producing a graded response to toxicants, but standards for controlling the quality of parental urchins have not been developed. In Chapter 1, experimental populations of Lytechinus variegatus were fed either organic romaine lettuce and organic carrots, or a feed formulated for sea urchins for 13 weeks. Growth demographics were assessed and F1 progeny were compared for sensitivity to the toxicants copper sulfate, 1,3,5-trinitrobenzene, and sodium dodecyl sulfate by acute embryonic and …

An increasing demand for organic crops in the US represents a considerable opportunity for organic, as well as conventional growers interested in exploring the transition to organic production. Renewed interest in organic farming has resulted in a need for research involving organic fertilizers. Limited research has been conducted on organic vegetable production with previous research conducted primarily outside the Deep South US. Field studies were conducted at the Louisiana State University (LSU) AgCenter Burden Center to investigate the effect of three levels of pre-plant organic NPK fertilizer (8-5-5, Nature Safe) combined with a sidedress application of organic NPK fertilizer (13-0-0, …

Resistant Starch Is Effective In Lowering Body Fat In A Rat Model Of Human Endocrine Obesity, Julina Ann Robert

LSU Master's Theses

Two studies were performed to determine the effects of resistant starch (RS) on body weight and fat. A 2x2 factorial design was used in both studies, and results were considered significant when p<0.05 for both studies. The first study examined the effects of RS in a high fat diet (44.8% of energy) on weight, fat, peptide-YY (PYY) levels, and cecal pH in male Sprague-Dawley rats. Rats were fed a low fat energy control diet for one week prior to diet treatment. On week two, rats were blocked by weight and fed one of the following diets for 12 weeks (n=10): low fat, energy control (LFEC); LF resistant starch (LFRS); high fat, energy control (HFEC); or high fat resistant starch (HFRS). RS did not lower weight or fat with either the HF or LF diets. RS consumption resulted in greater full and empty cecal weights, and a lower pH for the LFRS diet. This data indicate fermentation, even though weight and fat loss did not occur. This is contrary to previous reports with RS, which has been shown to decrease body fat compared to controls. The second study examined the effects of RS on the weight, fat, PYY levels, and glucagon-like peptide-1 (GLP-1) levels in female Sprague-Dawley rats. Ovariectomized (OVX) rats were used to represent rats prone to gaining weight, and sham rats represented normal rats. Rats were assigned to one of four groups (n=10): OVEC, OVRS, SHEC, or SHRS. Rats were fed the EC diet for 6 weeks prior to diet treatment to gain weight after surgery, and then blocked by weight and fat into diet treatment groups, and spent 13 weeks on treatment diets. Energy intake, total gastrointestinal weight, large intestine/cecum weight, and small intestine weight were all higher in RS fed rats relative to EC fed rats. Mesenteric, ovarian, perirenal, retroperitoneal, and total fat pads were lower in RS rats relative to EC rats. Although RS was not effective in lowering body weight or body fat in the first study, the data indicates that resistant starch may lower body weight and fat in postmenopausal women.

We Believe In The Systems That Keep Us Alive, Ezra Kellerman

LSU Master's Theses

ABSTRACT We Believe In the Systems That Keep Us Alive is a body of work that uses parallels identified between writing and media critique of contemporary events. The parallels are labeled as four specific systems: nutritional, administrative, life-support, and nurturing. Through a combination of interactive and object based sculpture, each system is represented with visual metaphor and allegory to place the viewer in a direct and specialized paradox. Paradoxes audience members encounter are intended to illustrate to the audience what conflicts can arise by being included in a system where governing agency of any sort does not meet with individual …

Food Handling Practices Of High-Risk Populations, Bobby Babak Rasulnia

Socioeconomic Disparities In Health: A Symposium On The Relationships Between Poverty And Health, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The disparities in health between the rich and poor are so striking, and the results so dire, that reducing the gap is an ethical imperative.

A strong and consistent finding of epidemiological research is that socioeconomic status (SES) is correlated with morbidity, mortality, and functioning. SES is a complex combination of income, education, and occupation. Theorists posit that material disadvantage, diminished control over life's circumstances, and lack of social acceptance all contribute to poor health outcomes. The relationship between SES and health often is referred to as a "gradient" because of the graded and continuous nature of the association; health …

Gonadal Cycle Of Northern Quahogs, Mercenaria Mercenaria (Linne, 1758), From Fished And Non-Fished Subpopulations In Narragansett Bay, Dora C. Marroquin-Mora, Michael A. Rice

Fisheries, Animal and Veterinary Sciences Faculty Publications

To determine if population density in areas closed to fishing in Narragansett Bay is causing differences in the reproductive potential of the organisms, this study used two approaches to determine the reproductive condition of the animals. The first approach consisted in employing a gravimetric condition index (CI) to evaluate the general condition of quahogs from nine different sites, 3 sites open conditionally for fishing (conditional areas) and 6 sites closed to fishing. The second approach was a determination of gonadal index (GI) of a subset of the sample sites, by histological observation of gonadal tissue sections. Initial sampling included determination …

The Balancing Act, David Weaver

Conference papers and presentations

Nutrient management is as much a global issue as a local one with a balance required between economics and environment, inherent biological limitations and expectations of nutrient use efficiency, and traditional fertiliser practices and actual enterprise nutrient requirements. The concept of nutrient balance depends on context and scale. Nutrient balance can be considered at a global scale, where issues of nutrient stocks, cycles, depletion and transfer of a particular element are important. For a single farm enterprise, nutrient balance might be considered in terms of phosphorus (P) inputs into and outputs from the enterprise. This is commonly known as a …

Reclamation Of Saline Soils Through Revegetation In Australia: Plants, Processes And People, Edward G. Barrett-Lennard

Conference papers and presentations

Secondary salinity (salinity induced by human activity) is a major world problem. Hydrological imbalances in landscapes cause watertables to rise, drawing salt from deeper in the soil profile to the soil surface, where the combined stresses of salinity and waterlogging threaten the growth of crops and pastures. The reversal of salinity by the broad‐scale reintroduction of perennial plants back into landscapes may not be economically feasible, but watertables may be at least partly directly drawn‐down by the grow th of salt tolerant plants (halophytes) on saltland . This review summarises data from Australia in which the water use by perennial …

Using Systematic Screening To Integrate Health Services In India And Senegal: Pilot Study Versus Scale-Up Results, James R. Foreit

Reproductive Health

This study examines the effectiveness of using systematic screening to integrate health services in India and Senegal. First, a pilot study of relatively small-scale experiments was undertaken to determine if systematic screening for unmet needs for health services could increase the number of preventive care services clients receive at healthcare visits. FRONTIERS then participated in the scale-up to test the effect of different supervision and training strategies on the frequency of provider screening. Results show that systematic screening may have the potential to produce important increases in the number of services provided in many developing country settings at the pilot …

Reproductive Health

The Population Council’s USAID-funded Frontiers in Reproductive Health (FRONTIERS) program, in collaboration with the Egyptian Ministry of Health and Population and the NGO Social Planning, Analysis and Administration Consultants, conducted an operations research study to measure the acceptability and effectiveness of two birth spacing message models in Upper Egypt. Overall, the study found that providing birth spacing messages to low-parity women during antenatal and postpartum care and also to husbands through community awareness activities was feasible and acceptable. As a result, birth spacing messages have been integrated into service delivery guidelines for antenatal and postpartum care, and IEC materials on …

Promoting Healthy Timing And Spacing Of Births In India Through A Community-Based Approach, M.E. Khan, Mary Philip Sebastian, Usha Sharma, Rukma Idnani, Kaushal Kumari, Bharati Maheshwari, Shahid Ashraf

Reproductive Health

The Indian Family Welfare Program, though successful in increasing contraceptive use among couples who have achieved their desired family size, has failed in educating people about the importance and need of using contraceptive methods for spacing births. With its Indian collaborators, the Population Council’s Frontiers in Reproductive Health (FRONTIERS) program undertook a study to test a model to increase use of postpartum contraception among young pregnant women with a parity of 0 or 1. The study showed that the Behavior Change Communication (BCC) model developed to promote Healthy Timing and Spacing of Pregnancy (HTSP) was effective in promoting the lactational …

Increasing The Accessibility, Acceptability And Use Of The Iud In Gujarat, India, M.E. Khan, Sitanshu Sekhar Kar, Vikas Kishor Desai, Pratibha Patel, B.P. Itare, Sandhya Barge

Reproductive Health

The USAID-funded FRONTIERS Program of the Population Council, in collaboration with the Department of Health & Family Welfare, Government of Gujarat, and the Center for Operations Research and Training, Vadodara, conducted an operations research study in India to test the hypothesis that by improving the demand for the IUD and simultaneously strengthening the technical competencies and counseling skills of the providers, use of the IUD use would increase. The findings show that demand-generation activities and provision of good-quality IUD services, together with a supportive programmatic environment, when carried out simultaneously showed increased acceptance of the IUD. The intervention could be …

Development Of A Quality Assurance Procedure For Reproductive Health Services For District Public Health Systems: Implementation And Scale-Up In The State Of Gujarat, M.E. Khan, Anurag Mishra, Vivek Sharma, Leila Caleb-Varkey

Reproductive Health

This project was carried out in India, in two districts each in Gujarat and Maharashtra states. It confirmed that quality assurance (QA) checklists and an implementation manual, developed by the USAID-funded Frontiers in Reproductive Health (FRONTIERS) Program of the Population Council in collaboration with UNFPA/India, are useful and effective tools that the Ministry of Health and Social Welfare (MOHFW) can use to monitor the quality of services provided by health facilities. It also demonstrated that this QA mechanism can be easily institutionalized at the district level management. One key lesson has been the critical role that the commitment of state …

Taking Critical Services To The Home: Scaling-Up Home-Based Maternal And Postnatal Care, Including Family Planning, Through Community Midwifery In Kenya, Annie Mwangi, Charlotte E. Warren

Reproductive Health

With support from USAID, the Population Council’s Frontiers in Reproductive Health (FRONTIERS) project supported the scaling up of a community-based model in Kenya that enabled women to give birth safely at home or be referred to a hospital when attended by a self-employed skilled midwife living in the community. To strengthen the sustainability of this approach FRONTIERS engaged a microfinance NGO to develop a training curriculum on basic business skills and financial literacy, and encouraged the community midwives (CMs) to form clusters or informal associations so that they could be trained in business skills. Following these interventions, CMs proved more …
