The aim of this study was to evaluate the potential effects of isomaltodextrin (IMD), a dietary saccharide polymer derived from enzymatically produced from starch, on the ability to alter immune response (IR) bias to hen egg ovalbumin (Ova) induced allergic inflammation in mice. Groups of Balb/c mice were pre-treated with various doses of IMD in drinking water (1.0, 2.5, and 5.0% w/v) for 6 weeks and subsequently sensitized to the Ova together with continuous administration of IMD. To evaluate changes in immune response bias, immunoglobulin isotype-associated antibody activity, concentrations of type 1 and 2 cytokines and the percentage of T-regulatory …

Emerging evidence shows that phytochemicals, the secondary plant metabolites present in a large variety of foods, have the potential ability in reducing the risk of cardiovascular diseases. However, the dosages of phytochemicals in the cellular and animal studies are too high to reach in humans by relevant foods or dietary supplement intake. The aims of this study were to investigate whether and how combined curcumin and luteolin synergistically inhibit tumor necrosis factor-alpha (TNF-α)-induced monocytes adhesion endothelium, a crucial step of the development of endothelial dysfunction, both in human vascular cells and mouse aortic endothelium. Our results show that combined curcumin …

Prevalence, Antibiotic-Resistance And Growth Profile Of Vibrio Spp., Isolated From Imported Fish In The Local Markets, Tarfa Ali Mohamed
Theses
Seafood and fish are important food components for a large section of the world population. Seafood is prone to bacterial contamination, many are pathogenic to human and marine animals, and three species, Vibrio mimicus, Vibrio parahaemolyticus, and Vibrio vulnificus, are responsible for most cases of seafood-related human illness caused by Vibrio species. The study on the prevalence of these microorganisms in seafood of the United Arab Emirates is vital due to the cultural background of the Emiratis as a coastal heritage.

Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith
Department of Food Science and Technology: Dissertations, Theses, and Student Research
There is potential to increase microbiota accessible carbohydrates (MAC) in whole grains through food processing. Therefore, different processing conditions for boiling and extrusion of whole wheat flour were studied for their effect on MAC. Processing conditions had a minimal effect on fermentation response using 2 fecal samples of disparate composition. However, the processing method had an impact on the fermentation of non-digestible carbohydrates and subsequent short chain fatty acids production, but only for a microbiome with high diversity and a predominance of microbes associated with dietary fiber intake. Subsequently, five processing methods: boiling, extrusion, unleavened bread, yeast bread, and sourdough …
