United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Grassland degradation has accelerated in recent decades in response to increased climate variability and human activity. Rangeland and grassland conditions directly affect forage quality, livestock production, and regional grassland resources. In this study, we examined the potential of integrating synthetic aperture radar (SAR, Sentinel-1) and optical remote sensing (Landsat-8 and Sentinel-2) data to monitor the conditions of a native pasture and an introduced pasture in Oklahoma, USA. Leaf area index (LAI) and aboveground biomass (AGB) were used as indicators of pasture conditions under varying climate and human activities. We estimated the seasonal dynamics of LAI and AGB using Sentinel-1 (S1), …

Revision Of The Genus Gilia Of Utah, Zachariah Jaramillo, Dr. Leigh Johnson

Journal of Undergraduate Research

The genus Gilia has historically been difficult to work with because identification of the genus via a dichotomous key relies heavily on the absence of characteristics instead of the presence of unique characteristics (Johnson et al., 2004). This has caused Gilia to become a polyphyletic group that serves as a “dumping ground” for odd species that do not easily fit in any other genus within the family. Studies using morphological and molecular data have identified species traditionally placed in Gilia that are really more closely related to other genera. For example, Gilia gilioides belongs in Allophyllum, Gilia capillaris belongs in …

Perception Of Speech And Song In Religious Music: A Neurological Approach, Dagan Pielstick, Francesca Lawson

Journal of Undergraduate Research

The relationship between speech and song has been an area of interest in evolutionary biology and neuroscience over the past two decades. Some evolutionary biologists have hypothesized that music and language descended from a protolanguage in early human communication (Brown 2000). At the same time, developments in technology have made it possible to analyze the activation of different parts of the brain, allowing us to see traces of this evolutionary history in the neural pathways of the brain (Patel 2008). Recent studies on language-music relationships both support and contradict the theory of a common protolanguage base for music and language …

Damselfies Of Vanuatu, Madison Lallatin, Seth Bybee

Journal of Undergraduate Research

Vanuatu is a string of active volcanic islands in Micronesia near Fiji and Australia. The islands undergo regular submersion and emersion from the ocean, and the most recent emergence was 2 million years ago (Hamilton et al. 2010). As a result, all organisms on the islands of Vanuatu have migrated there, likely from other islands, within the past 2 million years. Fiji is one likely candidate for contributing species, being geographically close to Vanuatu and exhibiting similar species. Fourteen of us went to Vanuatu for 6 weeks on a study abroad led by Dr. Seth Bybee to collect and observe …

Using Remote Video Systems To Measure Effectiveness Of Small Scale Mpas In Saipipi, Samoa, Calvin Quigley, Dr. Richard Gill

Journal of Undergraduate Research

Coral reefs represent an invaluable natural, providing $30 billion dollars of fishing and recreational profits worldwide, and housing nearly a quarter of the oceans species [1, 2]. However, threats such as climate change, ocean acidification, coastal development and overharvesting have destroyed more than a fifth of the worlds coral reefs in recent decades[3]. One of the most common management plans that has been implemented to help protect and restore coral reefs is the establishment of marine protected areas (MPAs)[4]. MPAs have been proven to be effective in helping restore fish populations and coral cover, however the majority of MPAs are …

Effectiveness Of Hospital Disinfectants Against Clostridium Spores, Bejamin Ogilvie, Richard Robinson

Journal of Undergraduate Research

Clostridium is a genus of anaerobic spore-forming bacteria notable for causing human infections. C. difficile has an especially high impact, affecting roughly 453,000 individuals in the U.S. in 2011 (1). C. tetani and C. perfringens infections occur much less frequently, although they remain clinically important. Disinfecting objects contaminated with Clostridium is challenging, as Clostridium spores are resistant to extreme temperature, desiccation, and most chemicals (2, 3). Clostridium is also frequently found within soil, making it a likely contaminant on almost any piece of medical equipment (3).

Currently, the U.S. EPA only requires sporicidal disinfectant efficacy tests against C. sporogenes, a …

Could Tk1 Suppress The Immune System And Promote Tumor Development?, Joshua Keller, Roman Kovtun, Kim O'Neill

Journal of Undergraduate Research

Cancer is a widespread disease that affects millions of people worldwide and in many cases is difficult to treat. In order to find new and better treatment, it is important to understand how this disease progresses. Thymidine Kinase 1 (TK1) is a recognized biomarker that is upregulated in cancer cells compared to healthy tissue. Although this protein is normally found inside the cells (cytosol), it becomes upregulated on the surface of malignant cells. Moreover, recent research shows that TK1 expression is further upregulated in breast cancer tissues that undergo a transition from stationary (epithelial) cells to more mobile (mesenchymal) cells. …

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.

Journal of Undergraduate Research

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 …

Nrf2 In Protecting Against Valproic Acid-¬‐Induced Oxidative Injury During Cellular Differentiation, Alyssa Palmer, Jason Hansen

Journal of Undergraduate Research

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 …

Towards On-Demand E. Coli-Based Cell-Free Protein Synthesis Of Tissue Plasminogen Activator, Seung-Ook Yang, Gregory H. Nielsen, Kristen M. Wilding, Merideth A. Cooper, David W. Wood, Bradley Charles Bundy

Faculty Publications

Stroke is the leading cause of death with over 5 million deaths worldwide each year. About 80% of strokes are ischemic strokes caused by blood clots. Tissue plasminogen activator (tPa) is the only FDA-approved drug to treat ischemic stroke with a wholesale price over $6000. tPa is now off patent although no biosimilar has been developed. The production of tPa is complicated by the 17 disulfide bonds that exist in correctly folded tPA. Here, we present an Escherichia coli-based cell-free protein synthesis platform for tPa expression and report conditions which resulted in the production of active tPa. While the activity …

Schrank, Dan Svedarsky, Steven Travis, Nancy Tuchman, Lisamarie Windham-Myers

United States Department of Agriculture Wildlife Services: Staff Publications

Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and forming monodominant vegetation stands due to traits such as robust size, rapid growth rate, and rhizomatic expansion. Increased nutrient inputs into wetlands and altered hydrologic regimes are among the principal anthropogenic drivers of Typha invasion. Typha is associated with a wide range of negative ecological impacts to wetland and agricultural …

Pediatric Palliative Care Oral History Project

Dr. Liben credits his initial venture into pediatric palliative care to his experiences of witnessing "unnecessary suffering" during his career in pediatric critical care. Dr. Liben states that he was attracted to how much "promise" that pediatric palliative care held in addressing more than just the medical needs of children and their families. He then recalls experiences he had with international leaders in the emerging field of pediatric palliative care. Dr. Liben describes how the field has evolved to be more patient- and family-centric while spanning across the intersections of pain management, chronic care, and complex care. Dr. Liben also …

Cd5 Deficient Mice Exhibit Altered Cognitive Function In Behavioral Studies, Tyler Cox, Dr. Scott Weber

Journal of Undergraduate Research

The immune system plays a role in protecting and maintaining the central nervous system (CNS). 1Dysfunctions within the immune system can affect the CNS and it is associated with diseases such as Multiple Sclerosis, Alzheimer’s and Parkinson’s disease. Having an imbalanced activation of immune cells within CNS results in cognitive impairments. CD5 is a protein on the surface of T cells and certain B cells that inhibits cellular activation and prevents immune cells from reacting too strongly to antigens and causing autoimmunity to our own tissues. Modulating CD5 and the immune system could affect the CNS and cognitive function. Observations …

Characterization Of Mutant Chemokine (C-C) Motif Receptor-Like 2 (Ccrl2) And Its Role In Inflammation And Alzheimer’S Disease, Meganne Ferrel, Dr. John S. K. Kauwe

Journal of Undergraduate Research

Alzheimer’s Disease (AD) is identified as a proteopathic disease that results from an extensive accumulation of amyloid plaques and neurofibrillary tangles in the brain. Several researchers have discovered that cerebrospinal fluid (CSF) contains biomarkers for AD such as Amyloid-beta and tau. Neuritic plaques in AD are surrounded by activated microglia and astrocytes which can initiate complement and inflammation in the presence of amyloid-beta. Macrophage inflammatory protein chemokine (C-C motif) ligand 4 (CCL4) is a biomarker found in CSF. A high level of expression is associated with risk of developing AD. CCL4 is expressed in a subpopulation of reactive astrocytes and …
