Increases in the prevalence of multiply resistant microbes have necessitated the search for new molecules with antimicrobial properties. One noteworthy avenue in this search is inspired by the presence of native antimicrobial peptides in the skin of amphibians. Having the second highest diversity of frogs worldwide, Colombian anurans represent an extensive natural reservoir that could be tapped in this search. Among this diversity, species such as Boana pugnax (the Chirique-Flusse Treefrog) are particularly notable, in that they thrive in a diversity of marginal habitats, utilize both aquatic and arboreal habitats, and are members of one of few genera that are ...
Lack Of Consensus On An Aging Biology Paradigm? A Global Survey Reveals An Agreement To Disagree, And The Need For An Interdisciplinary Framework, Alan A. Cohen, Anne M. Bronikowski, Luigi Ferrucci, Et Al.
Ecology, Evolution and Organismal Biology Publications
At a recent symposium on aging biology, a debate was held as to whether or not we know what biological aging is. Most of the participants were struck not only by the lack of consensus on this core question, but also on many basic tenets of the field. Accordingly, we undertook a systematic survey of our 71 participants on key questions that were raised during the debate and symposium, eliciting 37 responses. The results confirmed the impression from the symposium: there is marked disagreement on the most fundamental questions in the field, and little consensus on anything other than the ...
Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, 2020 Union University
Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush
Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover site and 4 ...
Ethical Implications Of The Legal Definition Of Brain Death In Light Of Modern Technological Advancements, 2020 Saint Michael's College
Ethical Implications Of The Legal Definition Of Brain Death In Light Of Modern Technological Advancements, Jordyn E. Fullaway
The Macksey Journal
Modern medical advancements in resuscitation and life support shifted the idea of death from a cardio-respiratory view to that of a neurocentric view. As a result, the definition of brain death (BD) emerged, which is the irreversible loss of brain function in both the brainstem and cerebral cortex. Consequentially, guidelines for determining BD were defined under law, and it is now legal to remove a patient from life support if they are diagnosed as brain dead. According to policy, one is considered brain dead if they have no brainstem reflexes, a lack of cerebral blood flow, and an absence of ...

Assessing Vulture Translocation As A Management Tool To Mitigate Airport Bird Strikes, Weber Galvão Novaes, Tarcísio Lyra Dos Santos Abreu, Rafael Soave Guerta
Collisions between wildlife and aircraft are a major safety concern for international aviation. In the Americas, vultures (Cathartidae) are considered to be one of the most hazardous bird species to airport operations. In this study, we evaluated the use of translocations as a management technique to reduce vulture abundance near the Manaus International Airport (MAO), Manaus, Brazil. The MAO is one of the busiest and most strategically important airports in South America, often referred to as the gateway to the Brazilian Amazon. We captured, wing-tagged, and translocated 98 vultures between August and October 2013 and between January and April 2014 ...
Three Gastrointestinal Assays, 2020 State University of New York College at Brockport
Three Gastrointestinal Assays, Bailey Majtyka
Senior Honors Theses
Gastrointestinal (GI) functionality relies on the spontaneous, rhythmic and coordinated propagation of muscular contractions in the GI tract, or GI motility. Without these coordinated motor patterns, digestion falters, and results in problems with digestion. Disrupted or un-coordinated motor patterns are associated with altered GI transit times. GI transit is the amount of time necessary for intestinal contents to move through the GI tract. GI transit is measured in patients complaining about abdominal discomfort to determine if discomfort results from a true dysmotility or from idiopathic symptoms. GI transit assays help to determine appropriate treatments but idiopathic symptoms, or pain from ...

An Investigation Into The Role Of Arf6 In Mch-Mediated Rearrangements In 3t3-L1 Preadipocytes, Bohdan Smich
Senior Honors Theses
Obesity has become a pandemic in our society. One potential method to alleviate this crisis is the use of pharmaceutical therapy to manage how our bodies metabolize the energy that we consume. Chronic overconsumption can lead to the activation of inflammatory responses and metabolic dysregulation, such as insulin resistance, and promote the obese condition. The pathways involved in the motility of pre-adipocyte cells are important in understanding how our bodies interpret and react to specific biochemical signals. This research is focused on a pathway that activates the expansion and migration of pre-adipocytes. Melanin-concentrating Hormone (MCH) is a neuropeptide that is ...

Regulation Of Innate Immunity In The C. Elegans Intestine By Olfactory Neurons, Kyle J. Foster
GSBS Dissertations and Theses
The intestinal epithelium represents one of the first lines of defense against pathogenic bacteria. Immune regulation at this critical barrier is necessary to maintain organismal fitness, and mis-regulation here has been linked to numerous debilitating diseases. Functional relationships between the nervous system and immune system have been found to be critical in the proper coordination of immune defenses at barrier surfaces, however the precise mechanisms underlying theses interactions remains unclear.
Through conducting a forward genetic screen utilizing the model organism Caenorhabditis elegans, we uncovered a surprising requirement for the olfactory neuron gene olrn-1 in the regulation of intestinal epithelial immunity ...
The Influence Of The Cellular Environment On Z-Dna Formation, 2020 State University of New York College at Brockport
The Influence Of The Cellular Environment On Z-Dna Formation, Amanda Hange
Senior Honors Theses
In the cell, chemically diverse solutes known as osmolytes accumulate in response to environmental stresses. To add to the understanding of how the environment inside a cell affects nucleic acid folding and function, we investigated the influence of cosolutes on the transition from B-DNA to Z-DNA in model DNA duplexes. Distinct from the familiar right-handed BDNA helical conformation, Z-DNA is a left-handed double helical structure with its phosphodiester backbone arranged in a zig-zag pattern that is unique to Z-DNA. Moreover, due to the correlation between Z-DNA formation potential and regions of active transcription, ZDNA is believed to serve a vital ...
The Significance Of The Nuclear Gene Ku80 In Mitochondrial Genome Stability Of Saccharomyces Cerevisiae, 2020 State University of New York College at Brockport
The Significance Of The Nuclear Gene Ku80 In Mitochondrial Genome Stability Of Saccharomyces Cerevisiae, Brooke Scott
Senior Honors Theses
Mitochondria are essential organelles in eukaryotes. They are often referred to as the powerhouse of the cell because mitochondria manufacture ATP, which is required for the successful completion of many cellular processes. Mitochondria have individual genomes, separate from the nuclear DNA, which encode proteins required for respiration. In humans, mutations in the mitochondrial DNA (mtDNA) result in the loss of mitochondrial function which leads to neuromuscular and neurodegenerative disorders. The focus of this study is to determine the role of the nuclear gene KU80 in maintaining mtDNA stability in the budding yeast, Saccharomyces cerevisiae. The product of the KU80 gene ...

International Journal of Speleology
White-Nose Disease (WND) has killed millions of hibernating bats in the US and Canada. Its causative agent, the fungus Pseudogymnoascus destructans was introduced to North America, but is native to Europe and Asia, where it is not associated with mass mortality. Although it is nearly impossible to eradicate an emerging wildlife disease, research on P. destructans spread mechanisms can aid in prevention of new introductions and development of better environmental management strategies. It is of particular importance to quantify the potential role of people visiting caves (cavers, tourists, bat researchers, etc.) whom inadvertently move P. destructans spores between sites, and ...

The COVID‐19 outbreak has infected over 6 million people across the world. The origin of COVID‐19 coronavirus (CoV) remains unknown, although pangolins have been suggested as potential hosts. We investigated two pangolins seized in Guangdong Province, China. Molecular screening revealed CoV in one pangolin (“Dahu”), while another (“Meidong”) was infected by Ehrlichia ruminantium. Dahu exhibited difficulty breathing, infections of lung, intestines, and nostrils, as revealed by computed tomography imaging and necropsy. Previous phylogenetic analyses showed bat coronavirus RaTG13 is closer to COVID‐19 CoV compared to pangolin coronavirus. Over 20 caregivers have had close physical contact with CoV ...

Great Lakes Snake: Estimating The Occupancy And Detection Probabilities Of The Eastern Massasauga Rattlesnake (Sistrurus Catenatus), Arin June Thacker
Detailed knowledge of a species’ range and distribution is important for understanding species persistence and developing species management plans. This issue is particularly pronounced in threatened species with wide-spread range and a low detectability in their natural environment, as surveying and successfully encountering this type of species is oftentimes difficult. One such species is the eastern massasauga rattlesnake (Sistrurus catenatus), a smallbodied pit viper with a distribution centered around the Great Lakes region. We used singleseason occupancy modeling in order to reassess the status of historic massasauga occurrences. We evaluated factors affecting eastern massasauga detection probability from a long-term dataset ...

Department of Biochemistry and Molecular Biology Faculty Papers
The genome-packaging motor of tailed bacteriophages and herpesviruses is a multisubunit protein complex formed by several copies of a large (TerL) and a small (TerS) terminase subunit. The motor assembles transiently at the portal protein vertex of an empty precursor capsid to power the energy-dependent packaging of viral DNA. Both the ATPase and nuclease activities associated with genome packaging reside in TerL. Structural studies of TerL from bacteriophage P22 have been hindered by the conformational flexibility of this enzyme and its susceptibility to proteolysis. Here, an unbiased, synthetic phage-display Fab library was screened and a panel of high-affinity Fabs against ...
Long‐Distance Natal Dispersal Is Relatively Frequent And Correlated With Environmental Factors In A Widespread Raptor, Hanna M. Mccaslin, T. Trevor Caughlin, Julie A. Heath
Biology Faculty Publications and Presentations
- Dispersal is a critical process influencing population dynamics and responses to global change. Long‐distance dispersal (LDD) can be especially important for gene flow and adaptability, although little is known about the factors influencing LDD because studying large‐scale movements is challenging and LDD tends to be observed less frequently than shorter‐distance dispersal (SDD).
- We sought to understand patterns of natal dispersal at a large scale, specifically aiming to understand the relative frequency of LDD compared to SDD and correlates of dispersal distances.
- We used bird banding and encounter data for American kestrels (Falco sparverius) to investigate the effects ...
