Rage And Sage: Therapeutic Modalities For Copd, Paul Reynolds Jun 2019

Rage And Sage: Therapeutic Modalities For Copd, Paul Reynolds

Journal of Undergraduate Research

Funding available through this MEG award has provided an opportunity for me to meet many academic objectives I’ve determined to be important at BYU. We have been successful in conducting pilot studies that reveal possible roles for SAGEs in ameliorating mechanisms of lung inflammation induced by and cigarette smoke (CS). Despite improvement in personal air quality during the past few decades, the rationale for studying mechanisms leading to adverse health effects remains important. This MEG award specifically provided opportunities for students to conduct meaningful research that led to the observation that alveolar epithelial cells and bronchiolar epithelial cells experience elevated …

The causes of the majority of birth defects remain largely unknown today. However, many chemicals known to cause defects are also known inducers of oxidative stress, resulting in faulty cellular function. This suggests an important link between oxidative stress and normal and abnormal embryonic development [1]. Oxidative stress is a phenomenon caused by an imbalance in the production of reactive molecules derived from oxygen called reactive oxygen species (ROS). Although basal levels of ROS are necessary in order for normal cell function to occur, an overabundance of ROS interact with molecules that they shouldn’t, disrupting vital cellular pathways. This is …


Regulation Of Trophoblast Invasion By Pyruvate Kinase Isozyme M2 (Pkm2): Preemptive To Pkm2 Activation Decreases Iugr Symptoms In Mice Exposed To Second-Hand Smoke, Juan Mejia, Juan Arroyo, Ph.D. Jun 2019

The placenta is an organ composed of highly vascular tissue. It plays an essential role in healthy fetal development as a mediator of gases and nutrients between the mother and fetus. Many complications can occur in this stage of fetal development, such as intrauterine growth restriction (IUGR) when the placenta’s invasive and vascular roles are inhibited. IUGR is an obstetric complication that affects over 10% of the population causing harmful symptoms to the fetus and mother. Physiologically, in the first trimester, high trophoblast cell invasion occurs, and the spiral arteries dilate to create a low resistance, high capacity vessel capable …


Antenatal Exposure To Secondhand Smoke Impacts Growth And Cardiopulmonary Energetics In 4-Week-Old Mice, Kaleb Egbert, Paul Reynolds Jun 2019

Antenatal Exposure To Secondhand Smoke Impacts Growth And Cardiopulmonary Energetics In 4-Week-Old Mice, Kaleb Egbert, Paul Reynolds

Journal of Undergraduate Research

Secondhand smoke (SHS) is a well-established cause of respiratory illness in infants and children who live in environments where exposure is common. Recent studies have been performed to examine the potential effects of SHS exposure on fetus’s before they are born1. The data collected suggests that antenatal exposure to SHS impacts cardiovascular and respiratory function through childhood and may even have lifelong ramifications, even if the exposure is terminated shortly after birth. In our study, we sought to determine the impact of SHS exposure during development in the womb would have on 4 week-old mice, or the equivalent of an …


Microbiota Composition Trends Among High Risk Asd Individuals, Hyrum Eddington, John M. Chaston Jun 2019

Autism Spectrum Disorder is a neurodevelopmental condition which significantly affects an individual’s social behavior and ability to function in daily living. Although there is a genetic component to the disorder, current research suggests that there are other factors that influence the onset of the disease. One of these factors is the gut microbiota of the individual. Because the human microbiome is a complex system that significantly varies from person to person, finding microbial markers indicative of certain disease can be challenging and problematic. Currently, there are no established protocols that can diagnosis an individual with autism on any criteria save …
