Ethical Foundations For The Lethal Management Of Double-Crested Cormorants (Phalocrocorax Auritus) In The Eastern United States: An Argument Analysis, Chelsea Batavia, Michael Paul Nelson

Chelsea Batavia, PhD

Lethal management of Double-crested Cormorants (Phalocrocorax auritus) has been implemented in many areas of the United States. In this paper, the philosophical method of argument analysis is used to assess ethical premises underlying the proposition that Double-crested Cormorant populations should be culled to reduce pressures on wild fisheries in the Great Lakes region of the eastern USA. This influential argument has been used to justify the destruction of more than half a million Double-crested Cormorants and hundreds of thousands of their nests and eggs. Three versions of the argument are formulated and assessed. It is shown that each of the …

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

David Turay, MD

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It …

Comparison Study Of The Averaged Sediment Microbial Enzyme Activities In Four Fecally-Contaminated Streams In The Same Watershed In Northeast Tennessee To Biochemical Oxygen Demand, Nitrate Concentration, And Phosphate Concentration, Brian G. Evanshen, Kurt J. Maier, Phillip R. Scheuerman

Phillip R. Scheuerman

Microbial enzyme activities (MEA’s) are measurements of microbial metabolism. These activities are dependent on the need for nutrients and respiration. This extended study evaluated four streams in the same watershed that had an approved fecal coliform Total Maximum Daily Load. Sediment and water samples were collected monthly for the first year of each specific stream study, and then quarterly to the end of 2006. Dehydrogenase, a measure of microbial respiration, along with acid phosphatase, alkaline phosphatase, galactosidase and glucosidase activities were measured using colorimetric assays. Biochemical oxygen demand (BOD) was determined using the standard 5-day test (BOD₅). Nitrate …

Comparison Of Microbial Water Quality Parameters Of Four Geographically Similar Creeks In Northeast Tennessee, Kimberlee K. Hall, L. K. Gallagher, Brian G. Evanshen, Kurt J. Maier, Phillip R. Scheuerman

Phillip R. Scheuerman

Four creeks within the Watauga River watershed in Northeast Tennessee are routinely monitored for water quality assessments. To identify sources and monitor remediation, Sinking Creek, Cash Hollow Creek, Buffalo Creek and Boones Creek are monitored for chemical and microbial parameters. These parameters include phosphates, nitrates, BOD and fecal coliforms. Sinking Creek is a tributary of the Watauga River with 10 miles of impaired water. Cash Hollow Creek enters the Watauga River at river mile 11.4 with 3.4 miles of impaired water. Boones Creek contains 18.6 impaired miles while the status of water quality in Buffalo Creek is not yet determined. …

Comparison Study Of Sediment Microbial Enzyme Activities To Biochemical Oxygen Demand, Nitrate Concentration, Phosphate Concentration In The Sediments Of A Fecally-Contaminated Stream In Northeast Tennessee Relative To Season And Land Use, Brian G. Evanshen, Kurt J. Maier, Phillip R. Scheuerman

Phillip R. Scheuerman

Microbial metabolism reacts quickly to environmental conditions. These reactions are dependent on the need for nutrients and respiration and can be measured using an assay of individual microbial enzyme activities (MEA’s). In this study, we measured MEA’s in the sediments of a stream in northeast Tennessee that had an approved fecal coliform Total Maximum Daily Load (TMDL). These values were compared to biochemical oxygen demand (BOD), phosphate concentration and nitrate concentration in the water column of this stream. Comparisons were grouped by season and land use. Stream sediments and water were collected monthly for one year and then quarterly for …

Common Parietal Activation In Musical Mental Transformations Across Pitch And Time, Nicholas E.V. Foster, Andrea Halpern, Robert J. Zatorre

Andrea Halpern

We previously observed that mental manipulation of the pitch level or temporal organization of melodies results in functional activation in the human intraparietal sulcus (IPS), a region also associated with visuospatial transformation and numerical calculation. Two outstanding questions about these musical transformations are whether pitch and time depend on separate or common processing in IPS, and whether IPS recruitment in melodic tasks varies depending upon the degree of transformation required (as it does in mental rotation). In the present study we sought to answer these questions by applying functional magnetic resonance imaging while musicians performed closely matched mental transposition (pitch …

An Ethogram For Benthic Octopods (Cephalopoda: Octopodidae), Jennifer Mather, Jean S. Alupay

Jennifer Mather, PhD

The present paper constructs a general ethogram for the actions of the flexible body as well as the skin displays of octopuses in the family Octopodidae. The actions of 6 sets of structures (mantle–funnel, arms, sucker–stalk, skin–web, head, and mouth) combine to produce behavioral units that involve positioning of parts leading to postures such as the flamboyant, movements of parts of the animal with relation to itself including head bob and grooming, and movements of the whole animal by both jetting in the water and crawling along the substrate. Muscular actions result in 4 key changes in skin display: (a) …

Chronic Hypobaric Hypoxia Modulates Primary Cilia Differently In Adult And Fetal Ovine Kidneys, Kiumars Shamloo, Juan Chen, Jasmine Sardar, Rinzhin T. Sherpa, Rajasekharreddy Pala, Kimberly F. Atkinson, William J. Pearce, Lubo Zhang, Surya M. Nauli

Lubo Zhang, PhD

Hypoxic environments at high altitude have significant effects on kidney injury. Following injury, renal primary cilia display length alterations. Primary cilia are mechanosensory organelles that regulate tubular architecture. The effect of hypoxia on cilia length is still controversial in cultured cells, and no corresponding in vivo study exists. Using fetal and adult sheep, we here study the effect of chronic hypobaric hypoxia on the renal injury, intracellular calcium signaling and the relationship between cilia length and cilia function. Our results show that although long-term hypoxia induces renal fibrosis in both fetal and adult kidneys, fetal kidneys are more susceptible to …

History Of The 3rs In Toxicity Testing: From Russell And Burch To 21st Century Toxicology, Martin L. Stephens, Nina S. Mak

Martin Stephens, PhD

Toxicity testing is a key part of the process of assessing the hazards, safety, or risk that chemicals and other substances pose to humans, animals, or the environment. Standardized methods for such testing, typically involving animals, began to emerge during the first half of the 20th century. In 1959, British scientists William Russell and Rex Burch proposed a framework for reducing, refining, or replacing animal use in toxicology and other forms of biomedical experimentation. This “3Rs” or “alternatives” approach emerged at a time of growing sensitivity to the use of animals in experimentation, and progress in its implementation has been …

Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. Mcgreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell

Paul McGreevy, PhD

Dogs offer unique opportunities to study correlations between morphology and behavior because skull shapes and body shape are so diverse among breeds. Several studies have shown relationships between canine cephalic index (CI: the ratio of skull width to skull length) and neural architecture. Data on the CI of adult, show-quality dogs (six males and six females) were sourced in Australia along with existing data on the breeds’ height, bodyweight and related to data on 36 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49) collected internationally using the Canine Behavioral Assessment and Research Questionnaire …
