Traumatic brain injury involves a primary mechanical injury that is followed by a secondary<br/>inflammatory cascade. The inflammatory cascade in the CNS releases cytokines which are<br/>associated with leukocytosis and a systemic immune response. Acute changes to peripheral<br/>immune cell populations post-TBI include a 4.5-fold increase of neutrophils 3 hours post-injury,<br/>and 2.7-fold or higher increase of monocytes 24 hours post-injury. Flow Cytometry is a<br/>technique that integrates fluidics, optics, and electronics to characterize cells based on their light<br/>scatter and antigen expression via monoclonal antibodies conjugated to fluorochromes. Flow<br/>cytometry is a valuable tool in cell characterization however the standard technique for data<br/>analysis, manual gating, is associated with inefficiency, subjectivity, and irreproducibility.<br/>Unsupervised analysis that uses algorithms packaged as plug-ins for flow cytometry analysis<br/>software has been discussed as a solution to the limits of manual gating and as an alternative<br/>method of data visualization and exploration. This investigation evaluated the use of tSNE<br/>(dimensionality reduction algorithm) and FlowSOM (population clustering algorithm)<br/>unsupervised flow cytometry analysis of immune cell population changes in female mice that<br/>have been exposed to a LPS-induced systemic inflammatory challenge, results were compared to<br/>those of manual gating. Flow cytometry data was obtained from blood samples taken prior to and<br/>24 hours after LPS injection. Unsupervised analysis was able to identify populations of<br/>neutrophils and pro-inflammatory/anti-inflammatory monocytes, it also identified several more<br/>populations however further inquiry with a more specific fluorescent panel would be required to<br/>establish the specificity and validity of these populations. Unsupervised analysis with tSNE and<br/>FlowSOM demonstrated the efficient and intuitive nature of the technique, however it also<br/>illustrated the importance of the investigator in preparing data and modulating plug-in settings.

All organisms perform best at a balanced point of intake where nutrients are ingested in specific amounts to confer optimal performance. However, when faced with limited nutrient availability, organisms are forced to make decisions which prioritize intake of certain macronutrients. While intake regulation has been more thoroughly studied in omnivores and carnivores, no research exists regarding lipid regulation in generalist herbivores. Traditionally, proteins and carbohydrates were thought to be the most important macronutrient for herbivore intake; however the large differences in lipid nutritional content between different plant species offers lots of potential for regulation of an important macronutrient. We studied whether generalist herbivores can regulate lipid intake, using the migratory locust (Locusta migratoria). Though herbivore protein and carbohydrate intake is well studied, less research studies regulation of lipid intake. We tested this by offering choice diets of varying carbohydrate and lipid content makeup and measuring consumption of each diet choice to determine overall carbohydrate and lipid intake. Four different lipid sources were used in order to control for taste or texture related confounds; canola oil, sunflower oil, grapeseed oil, and a lab designed synthetic oil based on the four most abundant fatty acids in common plant oils. On three out of four diet sources, groups evidences strong regulation of narrow intake target, with little disparity in overall intake of carbohydrate and lipid content between various choice diet treatments. Groups feeding on canola oil and sunflower oil based diets displayed the best regulation based on their having small disparities in intake between treatments, while those feeding on grapeseed oil based diets displayed wide variation in feeding behavior between treatments. Groups feeding on the synthetic oil based diet choice unexpectedly consumed much more carbohydrates than lipids when compared to all other groups. In conclusion, generalist herbivores are capable of regulating lipid intake.

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.
