Alcohol Consumption And Its Effects On The Liver, Eveline Weinreb Jan 2023

Alcohol Consumption And Its Effects On The Liver, Eveline Weinreb

The Science Journal of the Lander College of Arts and Sciences

Thousands of people die each year in the United States from alcohol related deaths. Why does the metabolism of alcohol cause severe damage to the body? Ethanol enters the body in the form of wine, and other alcoholic beverages and travels through the digestive system and then to the liver where it is metabolized. There are a series of steps involved in the breakdown of ethanol, and toxic byproducts are formed such as reactive oxygen species (ROS). These oxygen radicals can lead to damaged deoxyribonucleic acid (DNA) and to the formation of adducts. Chronic alcohol consumption can lead to liver …

Differences In The Neurological Pathways Of Innate And Learned Fear, Efrat Jacob Jan 2023

Differences In The Neurological Pathways Of Innate And Learned Fear, Efrat Jacob

The Science Journal of the Lander College of Arts and Sciences

Fear is a fundamental emotion for survival. However, not all fears are the same, leading to a necessary distinction between the two main subsections of fear; innate and learned. This research paper investigates whether the neural pathways underlying innate and learned fear are independent of each other. Using optogenetics and pharmacology, researchers have manipulated specific brain regions and circuits involved in fear processing, such as the amygdala, hypothalamus, and PAG (periaqueductal gray). By measuring the behavioral and physiological indicators of fear in rodents exposed to different types of stimuli, research suggests that there may be partial overlap between the neural …

Is Growth Hormone The Fountain Of Youth?, David Youlus Jan 2023

Is Growth Hormone The Fountain Of Youth?, David Youlus

The Science Journal of the Lander College of Arts and Sciences

Finding the cure for aging has been a sought-after quest for as long as the world has existed. Growth hormone has been shown as a possible treatment to negate the phenotypic effects of aging. Growth hormone is released from the adenohypophysis in response to sleep, exercise and stress. This in turn stimulates insulin-like growth factor-1 (IGF-1) secretion from the liver. Growth hormone circulation decreases in volume during aging. Studies on growth hormone therapy have indicated youth-like benefits, such as the reversal of sarcopenia, improved cognitive function, and boosted immunity. However, creating an imbalance of growth hormone and insulin-like factor-1 also …

Epilepsy And Treatment Resistance, Eva Kowalsky Jan 2023

Epilepsy And Treatment Resistance, Eva Kowalsky

The Science Journal of the Lander College of Arts and Sciences

Epilepsy is one of the most common debilitating neurological conditions. Individuals with epilepsy experience frequent seizures. Seizures are caused by hyperexcitable and hyper-synchronized neurons. Anti-seizure medications typically work to normalize the electrical activity in the brain. Many epileptic disorders are caused by genetic mutations, most of which cause mutations in ion channel mechanics. 30% of individuals with epilepsy do not respond to classic anti-seizure medications. A combination of factors typically contributes to treatment resistance. Individuals with drug-resistant epilepsy must turn to novel approaches for seizure relief. These approaches include following a ketogenic diet, using CBD products, utilizing a neurostimulator device, …

Stroke Recovery, Laya Brodie Jan 2023

Stroke Recovery, Laya Brodie

The Science Journal of the Lander College of Arts and Sciences

For years the brain was thought not to be regenerative, yet research has highlighted the role of neuroplasticity, neurogenesis, and deep brain stimulation in promoting brain recovery and enhancing stroke rehabilitation. Neuroplasticity is the brain’s ability to reorganize neural pathways in response to environmental or structural changes. Stroke recovery is possible due to the plasticity of the brain; the brain can create new neural pathways and neurons. Traditionally it was believed that humans were limited to generating new neurons in the brain, recent studies have shown that neurogenesis occurs throughout adulthood, particularly in the hippocampus, a region as- sociated with …

What Is The Best Treatment For Osteoporosis?, Joshua Sodden Jan 2023

What Is The Best Treatment For Osteoporosis?, Joshua Sodden

The Science Journal of the Lander College of Arts and Sciences

Osteoporosis is a bone disease that leads to frail bones, caused by osteoclasts destroying more bone than osteoblasts can create. It is more common among elderly people due to a lack of growth factors that promote osteoblasts. Estrogen plays a very important role in bone homeostasis of women; therefore post-menopausal women are most commonly affected because of their lack of estrogen production. Currently the FDA has approved eleven different drug treatments for osteoporosis. These treatments include anabolic treatments such as parathyroid hormone and anti-sclerostin, as well as catabolic treatments which include bisphosphonates, estrogen hormone, SERMs and anti-RANKL.

Epinephrine And Cardiac Arrest: The Catch-22, Shaina Friedman Jan 2023

Epinephrine And Cardiac Arrest: The Catch-22, Shaina Friedman

The Science Journal of the Lander College of Arts and Sciences

Epinephrine has been a standard of care treatment for cardiac arrest for the last century; however, the use of epinephrine began without a significant amount of research. In recent years, many have started to question whether epinephrine is an appropriate treatment for cardiac arrest. While epinephrine causes vasoconstriction of the blood vessels and directs much-needed blood flow to the heart, it has also been shown to harm the microvessels of the brain, causing ischemia and neurological damage. Many trials, studies, and surveys were conducted to determine the correct course of action involving the use of epinephrine during cardiac arrest. Additional …

Immunosuppression After Cardiac Transplantation: What Is The Best Approach?, Sara Batya Friedman Jan 2023

Immunosuppression After Cardiac Transplantation: What Is The Best Approach?, Sara Batya Friedman

The Science Journal of the Lander College of Arts and Sciences

Cardiac transplantation is a life-saving procedure for patients in end-stage heart failure. Since the first heart transplant in 1967, survival rates have steadily increased. This is largely on account of advancing immunosuppressive therapies, although immuno- suppression protocol still varies greatly among transplant centers, with no ideal regimen to follow. A fine balance lies between under-immunosuppression leading to rejection, and over-immunosuppression causing complications, toxicity, and adverse effects. Some successful therapies include steroids, lymphocyte proliferation inhibitors, and calcineurin inhibitors. Much of the available evidence as to which regimens have been successful is from retrospective analyses, indicating the need for more studies to …

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

Undergraduate Research Posters

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Epithelial Membrane Protein 3 (Emp3b) Is A Novel Regulator Of Sympathetic Nervous System Development In Zebrafish., Jessica M. White Jan 2023

Epithelial Membrane Protein 3 (Emp3b) Is A Novel Regulator Of Sympathetic Nervous System Development In Zebrafish., Jessica M. White

Theses and Dissertations

Notable progress has been made in understanding the development of the neural crest (NC). Neural crest cells (NCCs) can be divided into 4-5 subpopulations. A major lineage among trunk NC derivatives are sympathoadrenal (SA) cells, which give rise to the sympathetic nervous system (SNS). Trunk NCCs follow a ventromedial migration pathway where signals derived from the dorsal aorta instruct migrating NCCs to a SA cell fate. Defects in NC development can result in syndromes known as neurocristopathies. Neuroblastoma is one of the most common forms of pediatric cancer affecting nearly 800 infants each year in the United States (Takita et …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski Jan 2023

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Differences In Drifting Invertebrate Communities Across Arctic Ecozones And The Influence On Potential Growth Of Grayling (Thymallus Arcticus), Charles Chanyi

Theses and Dissertations (Comprehensive)

Invertebrate drift is a key process that potentially affects multiple levels of food web organization within stream environments. However, our understanding of the mechanistic drivers of drift in high latitude streams and subsequent bottom-up control that drift may have on fish predators in these environments remains understudied. This project aimed to gain the baseline knowledge of how drift functions across two major high latitude ecozones, the boreal forest and tundra, and how those possible differences in drifting community characteristics may impact drift-feeding Arctic grayling (Thymallus arcticus). These objectives were accomplished by characterizing stream environments across both ecozones, sampling …
