Since 1975, the prevalence of obesity has nearly tripled around the world. In 2016, 39% of adults, or 1.9 billion people, were considered overweight, and 13% of adults, or 650 million people, were considered obese. Furthermore, Cardiovascular disease remains to be the leading cause of death for adults in the United States, with 655,000 people dying from related conditions and consequences each year. Including fiber in one’s dietary regimen has been shown to greatly improve health outcomes in regards to these two areas of health. However, not much literature is available on the effects of corn-based fiber, especially detailing the individual components of the grain itself. The purpose of this preliminary study was to test the differences in influence on both LDL-cholesterol and triglycerides between treatments based on whole-grain corn flour, refined corn flour, and 50% refined corn flour + 50% corn bran derived from whole grain cornmeal (excellent fiber) in healthy overweight (BMI ≥ 25.0 kg/m2) adults (ages 18 - 70) with high LDL cholesterol (LDL ≥ 120mg/dL). 20 participants, ages 18 - 64 (10 males, 10 females) were involved. Data was derived from blood draws taken before and after each of the three treatments as well as before and after each treatment’s wash out periods. A general linear model was used to assess the effect of corn products on circulating concentrations of LDL-cholesterol and triglycerides. From the model, it was found that the whole-grain corn flour and the 50% refined corn flour + 50% corn bran drive from whole grain cornmeal treatments produced a higher, similar benefit in reductions in LDL-cholesterol. However, the whole grain flour, refined flour, and bran-based fiber treatments did not influence the triglyceride levels of the participants throughout this study. Further research is needed to elucidate the effects of these fiber items on cardiometabolic disease markers in the long-term as well as with a larger sample size.

The increase of Traumatic Brain Injury (TBI) cases in recent war history has increased the urgency of research regarding how veterans are affected by TBIs. The purpose of this study was to evaluate the effects of TBI on speech recognition in noise. The AzBio Sentence Test was completed for signal-to-noise ratios (S/N) from -10 dB to +15 dB for a control group of ten participants and one US military veteran with history of service-connected TBI. All participants had normal hearing sensitivity defined as thresholds of 20 dB or better at frequencies from 250-8000 Hz in addition to having tympanograms within normal limits. Comparison of the data collected on the control group versus the veteran suggested that the veteran performed worse than the majority of the control group on the AzBio Sentence Test. Further research with more participants would be beneficial to our understanding of how veterans with TBI perform on speech recognition tests in the presence of background noise.

This study was conducted to observe the effects of vitamin C supplementation upon the expression of sICAM-1 in asthmatic subject. Two groups were created, each with a sample size of 4 subjects. One group was the vitamin C group (VC) and the other was the placebo group (PL). The study was analyzed through observing concentrations of biomolecules present within samples of blood plasma and nasal lavages. These included vitamin C, sICAM-1 expression, and histamine. The following P-values calculated from the data collected from this study. The plasma vitamin C screening was p=0.3, and after 18 days of supplementation, p=0.03. For Nasal ICAM p=0.5 at Day 0, p=0.4 at Day 4, and p=0.9 at Day 18. For the Histamine samples p=0.9 at Day 0 and p=0.9 at Day 18. The following P-values calculated from the data collected from both studies. The plasma vitamin C screening was p=0.8, and after 18 days of supplementation, p=0.03. The change of vitamin C at the end of this study and the combined data both had a P-value that was calculated to be lower than 0.05, which meant that this change was significant because it was due to the intervention and not chance. For Nasal ICAM samples p=0.7 at Day 0, p=0.7 at Day 4, and p=1 at Day 18. For the Histamine p=0.7 at Day 0 and p=0.9 at Day 18. This study carries various implications although the study data was unable to show much significance. This was the second study to test this, and as more research is done, and the sample size grows, one will be able to observe whether this really is the mechanism through which vitamin C plays a role in immunological functions.

As a college student, living in an apartment or home with a kitchen, making your own food decisions can be daunting. After spending so much time either living at home and having food cooked for you or living in a dorm where food is provided, it is difficult to suddenly have to put so much thought into something that for so long you didn’t have to think about at all. Not only that, it sometimes feels like the media is screaming from all sides that you need to eat a certain way to be ‘healthy’ or ‘fit’. I hope to be able to make this process a bit easier for you through this guide I have put together from my own experience and education.
‘Healthy’ foods always seem like the best choice, but what does it really mean to be healthy? A ‘healthy diet’ can mean any number of things depending on who you ask and where you look. Media provides an endless sea of tips, tricks, and diets for ‘eating healthy’. Oxford defines health as a state of physical, mental, and social well-being with the absence of disease and infirmity; and healthy as indicative of, conducive to, or promoting good health1. It is easy to get caught up in the excitement of fad diets, but maintaining a healthy eating pattern can be quite simple when put into practice.

The concept of the Mediterranean Diet was described by Ancel Keys from the Seven Countries study, occurring in the 1960s. Unlike other diets, the Mediterranean Diet is a cultural tradition of nations surrounding the Mediterranean Sea. It involves the healthy pattern of food consumption and physical activity, which developed as an outcome of the locality's available food, other environmental resources, and overall cultural characteristics such as the polychromic time orientation of the Mediterranean nations. The Mediterranean Diet is a lifestyle structured around understanding a locality's natural conditions and resources and sustaining positive relationships between individuals, the community, and the components of their environment. The diet is largely plant based, where daily foods include grains, fruits, vegetables, olive oil, and dairy products. Seafood is eaten several times a week, while other animal products (poultry, meats, eggs) and sweets are eaten less often and in moderation. Alcohol, for those who drink it, is consumed several times a week. Research has shown a variety of health benefits from this diet. These benefits include preventing cardiovascular disease, certain cancers, Type 2 diabetes, Alzheimer's disease, age related macular degeneration of the eyes, kidney disease and osteoporosis. It also has been shown to improve conditions of metabolic syndrome, obesity, and depression. These favorable health outcomes are a result of the beneficial components within the foods commonly eaten. Fruits and vegetables are excellent sources of vitamins and minerals, which are needed to support cellular and overall organismal functioning, and nuts, vegetables, and fish also provide essential fatty acids like omega-3 and omega-6. The unifying component for all regions adhering to the Mediterranean Diet is the use of olive oil. Beyond being a healthy source of fat, it contains numerous chemical components with antioxidant properties. The Mediterranean region is an optimal region for olive tree growth and olive harvest, based on temperature and soil conditions. However, geographic differences, nutrient availability and age of olive trees can impact the quality of olive fruits and olive oil. Furthermore, climate change presents a challenge for sustaining the Mediterranean diet as it adds stress to plants and aquatic life environments. However, the diet shows promise of protecting the environment, as plant-based diets are found to have lower negative environmental impacts. In conclusion, the Mediterranean diet is an interconnected system of relationships that adapts to a locality's community, land, and climate.

Neuroinflammation is an important secondary injury response occurring after traumatic brain injury (TBI). Anxiety-like disorders are commonly exacerbated after TBI and are mediated through the amygdala; however, the amygdala remains understudied despite its important contribution in processing emotional and stressful stimuli. Therefore, we wanted to study neuroinflammation after experimental TBI using midline fluid percussion in rodent models. We assessed microglia morphology over time post-injury in two circuit related nuclei of the amygdala, the basolateral amygdala (BLA) and central amygdala of the nucleus (CeA), using skeletal analysis. We also looked at silver staining and glial fibrillary acidic protein (GFAP) to evaluate the role of neuropathology and astrocytosis to evaluate for neuroinflammation in the amygdala. We hypothesized that experimental diffuse TBI leads to microglial activation in the BLA-CeA circuitry over time post-injury due to changes in microglial morphology and increased astrocytosis in the absence of neuropathology. Microglial cell count was found to decrease in the BLA at 1 DPI before returning to sham levels by 28 DPI. No change was found in the CeA. Microglial ramification (process length/cell and endpoints/cell) was found to decrease at 1DPI compared to sham in the CeA, but not in the BLA. Silver staining and GFAP immunoreactivity did not find any evidence of neurodegeneration or activated astrocytes in the respectively. Together, these data indicate that diffuse TBI does not necessarily lead to the same microglial response in the amygdala nuclei, although an alternative mechanism for a neuroinflammatory response in the CeA likely contributes to the widespread neuronal and circuit dysfunction that occurs after TBI.

Annually approximately 1.5 million Americans suffer from a traumatic brain injury (TBI) increasing the risk of developing a further neurological complication later in life [1-3]. The molecular drivers of the subsequent ensuing pathologies after the initial injury event are vast and include signaling processes that may contribute to neurodegenerative diseases such as Alzheimer’s Disease (AD). One such molecular signaling pathway that may link TBI to AD is necroptosis. Necroptosis is an atypical mode of cell death compared with traditional apoptosis, both of which have been demonstrated to be present post-TBI [4-6]. Necroptosis is initiated by tissue necrosis factor (TNF) signaling through the RIPK1/RIPK3/MLKL pathway, leading to cell failure and subsequent death. Prior studies in rodent TBI models report necroptotic activity acutely after injury, within 48 hours. Here, the study objective was to recapitulate prior data and characterize MLKL and RIPK1 cortical expression post-TBI with our lab’s controlled cortical impact mouse model. Using standard immunohistochemistry approaches, it was determined that the tissue sections acquired by prior lab members were of poor quality to conduct robust MLKL and RIPK1 immunostaining assessment. Therefore, the thesis focused on presenting the staining method completed. The discussion also expanded on expected results from these studies regarding the spatial distribution necroptotic signaling in this TBI model.

Traumatic brain injury (TBI) is defined as an injury to the head that disrupts normal brain function. TBI has been described as a disease process that can lead to an increased risk for developing chronic neurodegenerative diseases, like frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS). A pathological hallmark of FTLD and a hallmark of ALS is the nuclear mislocalization of TAR DNA Binding Protein 43 (TDP-43). This project aims to explore neurodegenerative effects of TBI on cortical lesion area using immunohistochemical markers of TDP-43 proteinopathies. We analyzed the total percent of NEUN positive cells displaying TDP-43 nuclear mislocalization. We found that the percent of NEUN positive cells displaying TDP-43 nuclear mislocalization was significantly higher in cortical tissue following TBI when compared to the age-matched control brains. The cortical lesion area was analyzed for each injured brain sample, with respect to days post-injury (DPI), and it was found that there were no statistically significant differences between cortical lesion areas across time points. The percent of NEUN positive cells displaying TDP-43 nuclear mislocalization was analyzed for each cortical tissue sample, with respect to cortical lesion area, and it was found that there were no statistically significant differences between the percent of NEUN positive cells displaying TDP-43 nuclear mislocalization, with respect to cortical lesion area. In conclusion, we found no correlation between the percent of cortical NEUN positive cells displaying TDP-43 nuclear mislocalization with respect to the size of the cortical lesion area.

This paper examines the multifaceted challenges surrounding college students' nutrition, with a specific focus on Arizona State University (ASU). Examining economic shifts, psychological influences, nutrition knowledge, and body image dynamics, it reveals the profound impact on students' food security and eating behaviors. Despite existing initiatives, persistent gaps in resources remain, necessitating comprehensive interventions to support students effectively. In response, "The Ultimate Health Resource for ASU Students," a website, was developed as an innovative solution. This platform aims to empower students by providing a centralized hub to access vital resources, connect with peers, and discover nutritious recipes. Proposed strategies encompass expanding food pantry offerings, developing mobile applications for nutritional guidance, and fostering partnerships with local organizations. By tackling these challenges head-on and fostering a culture of support, ASU can ensure that all students have equitable access to nutritious food options and the necessary resources to thrive academically and personally. The website serves as a place of empowerment, offering practical solutions and fostering a sense of community among ASU students striving for optimal health and well-being.

Chutneys are a form of Indian condiment that can be made in many different flavors and paired with various foods. However, the availability of chutneys in the United States is very limited and many people have not tried them before. With this observation in mind, we founded A2Z Chutneys, which is a business that aims to distribute a variety of organic and locally produced chutneys. Through the Founders Lab program, A2Z Chutneys was created and research was conducted to justify the viability of our business. We were able to gather and interpret data from potential customers, which allowed us to identify a target market. Additionally, time was spent identifying and creating a variety of authentic and unique chutneys that have proven to be desired. This report demonstrates and outlines the feasibility of A2Z Chutneys in providing unique and desirable flavors to the population.
