Reduction Of Oxidative Stress And Storage Lesions (Rcsl) In Red Blood Cells - Analysis Of Ascorbic Acid (Aa), N-Acetylcysteine Amide (Ad4), And Serotonin (5-Ht), Shanmuka Gadiraju
Reduction Of Oxidative Stress And Storage Lesions (Rcsl) In Red Blood Cells - Analysis Of Ascorbic Acid (Aa), N-Acetylcysteine Amide (Ad4), And Serotonin (5-Ht), Shanmuka Gadiraju

Oxidative stress is a common occurrence in red blood cell (RBC) storage in blood banks throughout the world. Typically RBC units stored under routine standard protocol (stored in SAGM-CPD additive solution) can only be kept up to 42 days for transfusion usage before being discarded. I am studying the effects of Ascorbic Acid (AA), N-acetylcysteine amide (AD4), and Serotonin (5-HT) as additives in blood bank storage because I want to find out if these additives can reduce storage-induced oxidative stress on red blood cells (RBCs), in order to help my reader understand how potential blood storage additives can affect the …

Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …

The Impact Of Urbanization On Mosquito-Borne Viruses, Nikhita Puthuveetil
Undergraduate Research Posters
Mosquito-borne diseases such as yellow fever, dengue, and West Nile are rapidly emerging across the globe. Their emergence is often aided by the growth of their vector population, or the organisms that transmit the virus to the host. Urbanization and land use often destroys the habitat of the virus and its vector. However, the virus and its vector often survive despite the changes to its environment. The goal of this paper is to find out exactly how urbanization and changes in land use affect mosquito-borne viruses and how these viruses survive despite the destruction of their habitats. To understand how …

Community assemblages provide insight into ecosystem processes, both spatially and temporally. They interact with biotic and abiotic factors that vary with habitat structure, influencing community composition. Ecological theory demonstrates that species have the potential for a wide fundamental niche, but habitat range may be restricted by factors exposed to species in their realized niche. In barrier island ecosystems, edaphic and environmental characteristics (e.g. elevation and distance to shoreline) are major drivers determining where and how plant communities establish. Physical stressors, such as salt stress and drought influence community grouping and can alter plant function within the environment. With projected increases …

The literature shows an inverse association between exercise and mental disorders. The aim of this study is to further elaborate on this association with regards to exercise and its relationship with anxiety and depression in a college sample. The subject group focused on seniors in the Spit for Science data set which incorporated a total of 821 students. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ) to estimate the overall metabolic equivalents (MET’s) each student spent in walking, moderate, or vigorous activity levels in the previous week. Sum scores were used to measure depression and anxiety. Overall,the …

The axon initial segment (AIS) is fundamental for neuronal communication and action potential initiation, a characteristic which has been shown to be disrupted in inflammatory diseases such as Multiple Sclerosis (MS). Previous work from our lab has shown AIS breakdown in layer 5 of the cortex in a mouse model of MS known as experimental autoimmune encephalomyelitis (EAE). Moreover, it was shown that AIS breakdown was independent of demyelination but temporally correlated with microglial inflammatory reactivity. In order to determine if this pathology is specific to the cortex or affects other regions of the brain, we exploited these EAE induced …
Potential For Aerobic Exercise To Release Growth Factors To Induce Cognitive Changes In Children With Autism Spectrum Disorder, Maya Harrington
Potential For Aerobic Exercise To Release Growth Factors To Induce Cognitive Changes In Children With Autism Spectrum Disorder, Maya Harrington

Autism Spectrum Disorder (ASD) is becoming increasingly prevalent among adolescents, and while the number of individuals diagnosed with the disorder grows, there continues to be no cure or even a clear treatment path for ASD. This study analyzes the biological stimulations that create cognitive changes—which are induced by intensive aerobic exercise—within the brains of individuals ages 8-18 diagnosed with autism. I studied journal articles on the current treatments available for ASD, the increasing prevalence of the disease, the cognitive alterations of the autistic brain relative to the brains of individuals without the disease, the release of growth factors due to …

Chemical signatures that can indicate growth medium recipes or other key aspects of the production conditions are an important goal for forensic and biodefense agencies. In this study, Fatty Acid Methyl Ester (FAME) profiles were analyzed from Bacillus thuringiensis spores grown five different published medium recipes. B. thuringiensis was chosen due to its biochemical, structural, and genetic similarity to B. anthracis, a Biosafety Level III select agent and the organisms used in the Amerithrax attacks in 2001. The relative abundance of 13 different fatty acid biomarkers, spanning four structure classes, was compared across all spore samples. Differences in the …
