Mitochondrial Oxidative And Nitrosative Stress And Alzheimer Disease, D. Allan Butterfield, Debra Boyd-Kimball Sep 2020

Mitochondrial Oxidative And Nitrosative Stress And Alzheimer Disease, D. Allan Butterfield, Debra Boyd-Kimball

Chemistry Faculty Publications

Oxidative and nitrosative stress are widely recognized as critical factors in the pathogenesis and progression of Alzheimer disease (AD) and its earlier stage, amnestic mild cognitive impairment (MCI). A major source of free radicals that lead to oxidative and nitrosative damage is mitochondria. This review paper discusses oxidative and nitrosative stress and markers thereof in the brain, along with redox proteomics, which are techniques that have been pioneered in the Butterfield laboratory. Selected biological alterations in—and oxidative and nitrosative modifications of—mitochondria in AD and MCI and systems of relevance thereof also are presented. The review article concludes with a section …


Trace Mineral Leaching From Equine Compost, Ashley L. Fowler, Mieke Brummer-Holder, Karl A. Dawson Sep 2020

Trace Mineral Leaching From Equine Compost, Ashley L. Fowler, Mieke Brummer-Holder, Karl A. Dawson

Animal and Food Sciences Faculty Publications

Mineral leaching from compost can be environmentally disruptive. Little information is available regarding trace mineral leaching from equine-sourced compost. The objective of this study was to quantify the mineral content and leaching potential of compost produced from feces of horses fed different amounts and forms (organic or inorganic) of trace minerals. Nine horses were fed three treatments in a 3 × 3 replicated Latin Square design. The dietary treatments were provided as a daily pellet: CON (pellet without added trace minerals), ING (added inorganic trace minerals), and ORG (added organic trace minerals). The added trace minerals were Co, Cu, Mn, …

Pathways To Social Evolution And Their Evolutionary Feedbacks, Yimen G. Araya-Ajoy, David F. Westneat, Jonathan Wright Sep 2020

Pathways To Social Evolution And Their Evolutionary Feedbacks, Yimen G. Araya-Ajoy, David F. Westneat, Jonathan Wright

Biology Faculty Publications

In the context of social evolution, the ecological drivers of selection are the phenotypes of other individuals. The social environment can thus evolve, potentially changing the adaptive value for different social strategies. Different branches of evolutionary biology have traditionally focused on different aspects of these feedbacks. Here, we synthesize behavioral ecology theory concerning evolutionarily stable strategies when fitness is frequency dependent with quantitative genetic models providing statistical descriptions of evolutionary responses to social selection. Using path analyses, we review how social interactions influence the strength of selection and how social responsiveness, social impact, and non-random social assortment affect responses to …


Occupancy And Abundance Of Stream Salamanders Along A Specific Conductance Gradient, Jacob M. Hutton, Steven J. Price, Simon J. Bonner, Stephen C. Richter, Christopher D. Barton Sep 2020

Occupancy And Abundance Of Stream Salamanders Along A Specific Conductance Gradient, Jacob M. Hutton, Steven J. Price, Simon J. Bonner, Stephen C. Richter, Christopher D. Barton

Forestry and Natural Resources Faculty Publications

In the Central Appalachians (USA), mountaintop-removal mining accompanied by valley fills often leads to streams with elevated specific conductivity (SC). Thus, the ionic composition of freshwaters in this region is hypothesized to be a driver of the distribution and abundance of freshwater taxa, including stream salamanders. We examined the association between SC and stream salamander populations by conducting salamander counts in 30 southeastern Kentucky streams across a continuous gradient of SC that ranged from 30 to 1966 μS/cm. We counted 2319 salamanders across 5 species and, using a hierarchical Bayesian version of the N-mixture model, found a negative association between …


Aluminum Reproductive Toxicity: A Summary And Interpretation Of Scientific Reports, Robert A. Yokel Sep 2020

Aluminum Reproductive Toxicity: A Summary And Interpretation Of Scientific Reports, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Publications addressing aluminum (Al)-induced reproductive toxicity were reviewed. Key details were compiled in summary tables. Approximate systemic Al exposure, a measure of bioavailability, was calculated for each exposure, based on the Al percentage in the dosed Al species, Al bioavailability, and absorption time course reports for the exposure route. This was limited to laboratory animal studies because no controlled-exposure human studies were found. Intended Al exposure was compared to unintended dietary Al exposure. The considerable and variable Al content of laboratory animal diets creates uncertainty about reproductive function in the absence of Al. Aluminum-induced reproductive toxicity in female mice and …

The National Health and Nutrition Examination Survey (NHANES) is a scheme of studies with the objective of measuring the health and nutritional status of adults and children in the United States. The survey is unique in that it has a clinical component (NCT00005154), and combines interviews and physical examinations into its data sets. NHANES is an important program of the National Center for Health Statistics (NCHS). NCHS is a unit of the Centers for Disease Control and Prevention (CDC) and has the responsibility for producing vital and health statistics for the United States. Data from the NHANES studies …

Potential For Bacteriophage Cocktail To Complement Commercial Sanitizer Use On Produce Against Escherichia Coli O157:H7, Badrinath Vengarai Jagannathan, Steven Kitchens, Paul Priyesh Vijayakumar, Stuart Price, Melissa Morgan

Animal and Food Sciences Faculty Publications

The increasing concern for food safety has created a need to evaluate novel techniques to eliminate or control pathogens, resulting in safe food. In this study, four bacteriophages of bovine origin, specific to E. coli O157:H7, were successfully isolated and characterized. A microplate reader assay demonstrated the efficacy of the bacteriophage (phage) cocktail against E. coli O157:H7 resulting in a significant reduction (p < 0.01) in the target pathogen population. The phage cocktail demonstrated significant efficacy (p < 0.05) against E. coli O157:H7 in the presence of the most utilized sanitizers in the United States, namely 100 parts per million (ppm) free chlorine and 100-ppm peroxyacetic acid. Survival in the sanitizer concentrations demonstrates the potential …

Plant and Soil Sciences Faculty Publications

Previous results from our lab have shown that using an optical sorter to identify Fusarium head blight (FHB) resistant breeding lines was effective at reducing the toxin deoxynivalenol (DON) and FHB-associated kernel damage. In this paper we quantified the proportion of desirable genotypes at FHB resistance QTL in lines from three selection cycles of optical sorting. Breeding lines were genotyped at loci on chromosomes 3BS, 2DL, and 5A using the following DNA markers: TaHRC, CFD233, and GWM304. TaHRC is a KASP marker for Fhb1, a major FHB resistance QTL on chromosome 3BS. CFD233 is an SSR marker for Qfhs.nau-2DL …

Behaviors may enhance fitness in some situations while being detrimental in others. Linked behaviors (behavioral syndromes) may be central to understanding the maintenance of behavioral variability in natural populations. The spillover hypothesis of premating sexual cannibalism by females explains genetically determined female aggression towards both prey and males: growth to a larger size translates into higher fecundity, but at the risk of insufficient sperm acquisition. Here, we use an individual-based model to determine the ecological scenarios under which this spillover strategy is more likely to evolve over a strategy in which females attack approaching males only once the female has …
