and kidney disease. However, the impact of short term high fat intake on the etiology of kidney disease has not been well-studied. Therefore, this study examined the impact of a six week HFD (60% fat) on kidney structure and function in young male Sprague-Dawley rats. Previous studies have shown that these animals develop indices of diabetes compared to rats fed a standard rodent chow (5% fat) for six weeks. The hypothesis of this study is that six weeks of HFD will lead to early stages of kidney disease as evidenced by morphological and functional changes in the kidney. Alterations in morphology were determined by measuring structural changes in the kidneys (changes in mass, fatty acid infiltration, and structural damage). Alterations in kidney function were measured by analyzing urinary biomarkers of oxidative RNA/DNA damage, renal tissue lipid peroxidation, urinary markers of impaired kidney function (urinary protein, creatinine, and hydrogen peroxide (H2O2)), markers of inflammation (tumor necrosis factor alpha (TNFα) and interleukin 6 (IL-6)), as well as cystatin C, a plasma biomarker of kidney function. The results of these studies determined that short term HFD intake is not sufficient to induce early stage kidney disease. Beyond increases in renal mass, there were no significant differences between the markers of renal structure and function in the HFD and standard rodent chow-fed rats.
Reducing the amount of error and introduced data variability increases the accuracy of Western blot results. In this study, different methods of normalization for loading differences and data alignment were explored with respect to their impact on Western blot results. GAPDH was compared to the LI-COR Revert total protein stain as a loading control. The impact of normalizing data to a control condition, which is commonly done to align Western blot data distributed over several immunoblots, was also investigated. Specifically, this study addressed whether normalization to a small subset of distinct controls on each immunoblot increases pooled data variability compared to a larger set of controls. Protein expression data for NOX-2 and SOD-2 from a study investigating the protective role of the bradykinin type 1 receptor in angiotensin-II induced left ventricle remodeling were used to address these questions but are also discussed in the context of the original study. The comparison of GAPDH and Revert total protein stain as a loading control was done by assessing their correlation and comparing how they affected protein expression results. Additionally, the impact of treatment on GAPDH was investigated. To assess how normalization to different combinations of controls influences data variability, protein data were normalized to the average of 5 controls, the average of 2 controls, or an average vehicle and the results by treatment were compared. The results of this study demonstrated that GAPDH expression is not affected by angiotensin-II or bradykinin type 1 receptor antagonist R-954 and is a less sensitive loading control compared to Revert total protein stain. Normalization to the average of 5 controls tended to reduce pooled data variability compared to 2 controls. Lastly, the results of this study provided preliminary evidence that R-954 does not alter the expression of NOX-2 or SOD-2 to an expression profile that would be expected to explain the protection it confers against Ang-II induced left ventricle remodeling.
The purpose of this cookbook and ingredient index is to simplify the reasoning behind eating a plant based diet--including how it can be beneficial to your health, and what benefits each ingredient provides. These recipes have been cultivated and modified over time to provide nutritious meals that are also tasty. I was introduced to healthy eating at a young age, and have been fascinated by it ever since. The recipes and information conveyed about a plant based diet have come from the many books read and research I have done on the subject. This paper will walk you through how I started this journey, and go on to show a basic overview of what makes up the foods we consume and why we need them. The cookbook portion of my Thesis contains recipes for breakfast, lunch, dinner, snacks, sauces, and dessert. Following the cookbook is an ingredient index that goes through the majority of ingredients used in my recipes, and what health benefits they provide. I hope that by reading this, others will be inspired to use more plant-based whole foods in their diet, and realize the healing that can come from them.
As mindsets on wellness change, dietary restrictions become more prevalent, and there is more food and beverage innovation, the general public desires more options in daily life. Holistic wellness trends and plant-based options are being welcomed into many personal routines. With substantial commitments and dietary restrictions, guests onboard cruises need additional food and beverage options. Values of Millennials and Generation Z will also need to be considered as they mature into adulthood and gain more buying power. Both generations value experiences over material items, holistic wellness, and inclusivity. Thus, minor additions of plant-based, allergy-friendly, and/or nutritional items onboard would be beneficial to ships within the rapidly growing cruise line industry. Many cruise lines have already begun to make slight changes to their menus and selections, such as plant-based juice bars and notations on menus for vegan or allergy-friendly items. While it is difficult to satisfy all, cruise lines must be more proactive in catering to the lifestyle changes being made by guests if they hope to remain competitive in the leisure travel market.
