Camilo Mejia and Juan Arroyo, PhD, Physiology and Developmental Biology Introduction Pregnancy necessitates interactions between the mother and the fetus, and the placenta is the medium through which this is accomplished. Many complications during pregnancy, such as intrauterine growth restriction (IUGR) and preeclampsia (PE) arise from abnormalities in trophoblast cells of the human placenta. Trophoblast […]

Dani Peterson and Jonathan Wisco, PDBio Introduction Due to its long and complicated trajectory through the cranium, facial nerve VII (CN VII) (see figure 1) can be damaged in surgeries, sometimes resulting in facial muscle paralysis. Surgical removal of acoustic neuromas and parotid tumors, in addition to surgical repair of the temporomandibular joint disorder are […]

Bradley Prince and Jeffery Edwards, PDBIO Each year millions of people are affected by Alzheimer’s disease, one of the most common forms of dementia. Extensive research has shown that Alzheimer’s affects the hippocampus, the part of the brain principally responsible for learning and memory. The mechanisms responsible for learning and memory are just beginning to […]

Nicholas Saguibo and Dr. Marc Hansen, Physiology and Developmental Biology Introduction The TGF-β signaling pathway has been researched extensively over the past few years, and has been shown to be active in the majority of metastatic tumors. Interestingly, tumors expressing TGF-β activity are positively correlated with poorer prognosis in patients, making it a logical target […]

Teresa Nufer (St. Pierre) and Jeffrey G. Edwards, Physiology and Developmental Biology Both stress and exercise have significant physiological effects. Researchers have studied these effects throughout the body, and current evidence suggests that exercise and stress also have profound effects on the brain. While stress decreases brain function, exercise has been show to enhance brain […]

Jacob Trotter and Dr. Jeffrey Edwards, Department of Physiology and Developmental Biology Introduction The hippocampus is an area of the brain that mediates learning and memory by changing the properties of synapses between its neurons. This ability of synapses to change is known as synaptic plasticity. Long-term potentiation (LTP), a long-lasting increase in signal transmission […]

Brandon Herrington and Jonathan Wisco, Department of Physiology and Developmental Biology Introduction As the 6th leading cause of death in the United States1, and because of the significant deterioration it causes in the quality of life of its victims, Alzheimer’s disease is an area where research to improve its early diagnosis is paramount to establishing […]

Braden Tucker and Dr. Benjamin Bikman, Physiology and Developmental Biology Introduction: With the unabated rise in obesity in the United States and globally (1), increasing efforts are being devoted to understand and prevent both the onset and the consequences of excess fat gain. As evidenced by health trends, efforts to curtail weight gain have proven […]

Rachel Schneider and Dr. Jeff Edwards, Physiology and Developmental Biology Introduction My project goal was to understand how G-protein coupled receptor 55, (GPR55), a novel cellular pathway in the hippocampus, contributes to learning and memory. Recent research of neurodegenerative diseases, particularly Alzheimer’s, has primarily focused on understanding how learning occurs and how memories are encoded […]

Mitchell Gleed and Professor David D. Busath, M.D., Physiology and Developmental Biology INTRODUCTION Influenza is responsible for millions of hospitalizations and deaths every year. Treating the influenza virus has become increasingly difficult since mutant viruses have rendered previously viable drugs ineffective. New drug-screening procedures are now necessary in order to speed up the process of viable drug […]
