The Health And Nutrition Of Migrant Farm Workers In South Carolina, Abel Caballero
The Health And Nutrition Of Migrant Farm Workers In South Carolina, Abel Caballero
All Theses
ABSTRACT
Migrant farm workers--a high percentage of which are Hispanic--are an extremely disadvantaged population that experiences several barriers, including language, nutrition, transportation, and access to health services. This population also suffers from numerous diseases (obesity, diabetes, and heart disease) and experiences various hazards associated with risky work, such as pesticide exposure. This study included data collection on basic health and nutrition barriers to identify areas where programs and policies can be modified to better serve migrant farm workers. In addition, data was examined to determine the effect of all-inclusive educational intervention on nutrition, dental, fitness, and food safety issues by …
The Effects Of Suspended Sediment On The Aquatic Organisms Daphnia Magna And Pimephales Promelas, Neil Capper
The Effects Of Suspended Sediment On The Aquatic Organisms Daphnia Magna And Pimephales Promelas, Neil Capper
All Theses
Land use change results in significant amounts of soil migrating into aquatic streams during storm events. This suspended sediment, even in the absence of adsorbed contaminants, may be a significant stressor to aquatic organisms. The data on ecological effects of suspended sediment has mainly focused on salmonids or ecosystem level consequences such as habitat alteration. Few studies have quantified physiologic effects of suspended solids on water column organisms. The purpose of this research was to determine the effects of suspended clay on Daphnia magna and Pimephales promelas. Results of 7 d toxicity tests with D. magna in natural and …
Pro-Inflammatory Properties Of Flavobacterium Columnare Cells And Products On Channel Catfish (Ictalurus Punctatus) Neutrophils, Shannon Billings
Pro-Inflammatory Properties Of Flavobacterium Columnare Cells And Products On Channel Catfish (Ictalurus Punctatus) Neutrophils, Shannon Billings
All Theses
Flavobacterium columnare and Edwardsiella ictaluri are the leading causes for losses in the aquaculture industry. The losses from the diseases caused by these pathogens total $2.5 million for catfish and $100 million for total aquaculture. F. columnare's infection rates and stressors associated with outbreaks have been well-characterized, but the specific inflammatory responses of catfish neutrophils to the bacteria have not been studied. The objective, therefore, was to investigate the pro-inflammatory effects of the outer membrane proteins, extracellular products, and whole live bacteria, heat-killed (HK), and formalin-killed (FK) F. columnare and E. ictaluri to determine the effects on channel catfish phagocyte …
Comparison Of Bioactivities And Composition Of Curcumin-Free Turmeric (Curcuma Longa L.) Oils From Different Sources, Yongxiang Yu
Comparison Of Bioactivities And Composition Of Curcumin-Free Turmeric (Curcuma Longa L.) Oils From Different Sources, Yongxiang Yu
All Theses
Composition, antioxidant capacities and cell inhibition properties of curcumin-free turmeric (Curcuma longa L.) oils from different sources were evaluated by chromatographic method, two different in vitro antioxidative activity assays (DPPH* free radical scavenging assay and reducing power assay) and two different cancer cell lines (Caco-2 and MCF-7). Turmeric oil A (TOA) contains zingiberene, turmerone, and ar-turmerone, while turmeric oil B (TOB) contains 1-phellandrene and α-terpinolene as the major compounds. The antioxidant tests showed that both turmeric oils possessed strong free radical scavenging activities and high reducing powers compared with standard antioxidants such as BHT and commercial rosemary oil (RO). …
Revision Of The Males Of The Hydrospyche Scalaris Group In North America (Trichoptera: Hydropsychidae), James Korecki
Revision Of The Males Of The Hydrospyche Scalaris Group In North America (Trichoptera: Hydropsychidae), James Korecki
All Theses
The genus Hydrospsyche Pictet sensu stricto in North America is divided into three species groups, the Hydrospyche cuanis Ross Group Ross, the Hydropsyche depravata Hagen Group Ross, and the Hydropsyche scalaris Hagen Group Banks. Thirty-one of thirty-six described species are recognized in the Hydropsyche scalaris Group. Examination of adult males resulted in 5 junior subjective synonyms and one possible new species based on a single exemplar from Sevier County, Utah. Hydropsyche bidens Ross 1938, H. orris Ross 1938, and H. alvata Denning 1949 are junior synonyms of Hydropsyche incommoda Hagen 1861. Hydrospyche rossi Flint, Voshell and Parker, 1979 and H. …
Heat Inactivation Of Thermo-Resistant Bacteria Isolated From Poultry Offal, Lina Ramirez-Lopez
Heat Inactivation Of Thermo-Resistant Bacteria Isolated From Poultry Offal, Lina Ramirez-Lopez
All Theses
ABSTRACT The presence of thermo-resistant bacteria in products from the rendering industry is a concern in the United States because only about 80% of the rendering industries use thermal processing to eliminate bacteria. The objective of this study was to determine the thermal inactivation characteristics of thermo-resistant bacteria from raw rendering materials. Ground beef with 21% protein, 19% fat, and 60% moisture was used as a model media to simulate raw rendering material. Raw animal co-products were heated at 91, 95, 96¡C for 90 min, then surviving bacteria were recovered. These heat resistant isolates were inoculated into meat samples then …
Child Feeding Practices And Nutrition Education Needs Of The Latino Population In South Carolina, Claire Kirkpatrick
Child Feeding Practices And Nutrition Education Needs Of The Latino Population In South Carolina, Claire Kirkpatrick
All Theses
The Latino population in South Carolina is rapidly growing. Much of this population is low-income and many have a low level of education. Latinos have a greater incidence of obesity and the resulting diseases than other ethnicities and Latino children are no exception. It is important to provide nutrition education to caregivers so that child overweight and obesity can be prevented in this population. In order to provide effective nutrition education it is essential to know what behaviors need to be targeted. This study used qualitative and quantitative methods to examine the child feeding practices used by this population to …
