Characterization And Analysis Of Pcs1 Gene From Wheat, Haris Ahmed Khan, Ayaz Ahmad, Sehar Nawaz Nov 2016

Characterization And Analysis Of Pcs1 Gene From Wheat, Haris Ahmed Khan, Ayaz Ahmad, Sehar Nawaz

Journal of Bioresource Management

Wheat (Triticum aestivum) is an important cereal crop grown worldwide on large areas. Yields of wheat are decreasing worldwide due to heavy metal contamination. A number of genes have been characterized as those that confer tolerance to cadmium stress. PCS1 is one of them. Phytochelatins have a key role in the detoxification of heavy metals in plants. However, the mechanism behind the detoxification remains unknown and wheat genes related to detoxification have not yet been identified. Here we report the isolation of cDNA encoding of phytochelatin synthase (PCS) from wheat (var. Galaxy 2013). The AtPCS1 cDNA sequence contained …

Pyruvate Oxidase Of Streptococcus Pneumoniae Contributes To Penumolysin Release, Joseph C. Bryant, Ridge C. Dabbs, Katie L. Oswalt, Lindsey R. Brown, Jason W. Rosch, Keun S. Seo, Janet R. Donaldson, Larry S. Mcdaniel, Justin A. Thornton

Faculty Publications

Background

Streptococcus pneumoniae is one of the leading causes of community acquired pneumonia and acute otitis media. Certain aspects of S. pneumoniae’s virulence are dependent upon expression and release of the protein toxin pneumolysin (PLY) and upon the activity of the peroxide-producing enzyme, pyruvate oxidase (SpxB). We investigated the possible synergy of these two proteins and identified that release of PLY is enhanced by expression of SpxB prior to stationary phase growth.

Results

Mutants lacking the <>spxB gene were defective in PLY release and complementation of spxB restored PLY release. This was demonstrated by cytotoxic effects of sterile filtered …

Radiation Damage In Xfel: Case Study From The Oxygen-Evolving Complex Of Photosystem Ii, Muhamed Amin, Ashraf Badawi, S.S. Obayya

Publications and Research

Structural changes induced by radiation damage in X-ray crystallography hinder the ability to understand the structure/function relationship in chemical reactions. Serial femtosecond crystallography overcomes this problem by exposing the sample to very short and intense laser pulse leading to measurement before destruction. Here we use molecular modeling to map the radiation damage during the 10–50 fs to the intensity, the energy and the time duration of the laser pulse on the oxygen-evolving complex (OEC) of photosystem II. In the model, the nuclei move classically in a fully quantum potential created by electron density under the effect of strong laser pulse …

Responding To Modern Flooding: Old English Place-Names As A Repository Of Traditional Ecological Knowledge, Richard L.C. Jones Nov 2016

Responding To Modern Flooding: Old English Place-Names As A Repository Of Traditional Ecological Knowledge, Richard L.C. Jones

Journal of Ecological Anthropology

Place-names are used to communicate Traditional Ecological Knowledge (TEK) by all indigenous, aboriginal and First Nations people. Here and for the first time, English place-names are examined through a TEK lens. Specifically, place-names formed in Old English—the language of the Anglo-Saxon—and coined between c. 550 and c. 1100 A.D., are explored. This naming horizon provides the basic name stock for the majority of English towns and villages still occupied today. While modern English place-names now simply function as convenient geographical tags Old English toponymy is shown here to exhibit close semantic parallels with many other indigenous place-names around the world. …

Effect Of Microgravity On The Contraction And Cytoskeletal Remodeling Of A7r5 Smooth Muscle Cells, Danielle N. Gibson, Mark Will Casto Jr., Michael E. Fultz Nov 2016

Effect Of Microgravity On The Contraction And Cytoskeletal Remodeling Of A7r5 Smooth Muscle Cells, Danielle N. Gibson, Mark Will Casto Jr., Michael E. Fultz

Posters-at-the-Capitol

Smooth muscle presents several unique contractile properties when compared to striated muscle. Data suggests that differential remodeling of the alpha-actin and beta-actin and the regulation of such remodeling may play an essential role in smooth muscle contraction. At rest both alpha- and beta-actin both exhibit a cable-like appearance. During contraction, alpha-actin appears to undergo significant remodeling with dissolution on the majority of the cables and the formation of podosomes where it demonstrates co-localization with myosin while beta-actin retains a cable-like appearance. While the remodeling of the two actin domains has been characterized under normal gravity little is known regarding cytoskeletal …

Pt-Mal-Lhrh Mediates Breast Cancer Cell Cytotoxicity Through Increased Apoptosis, Kendall E. Collins

Posters-at-the-Capitol

In the United States one in eight women will be afflicted with breast cancer. It is estimated that in 2016 there will be approximately 246,600 new invasive breast cancer cases and 61,000 new non-invasive cases. Triple negative breast cancers account for 15% of all breast cancers and are significantly more aggressive than other subtypes. Treatment options for triple negative breast cancer are limited due to the cancers not expressing the estrogen, progestogen, or herceptin receptors making them unresponsive to hormonal therapy. Our recent work centers around developing a novel chemotherapeutic agent that will direct therapy selectively to triple negative (4T1) …

Development Of A Risk Assessment Framework To Predict Invasive Species Establishment For Multiple Taxonomic Groups And Vectors Of Introduction, Alisha D. Davidson, Abigail J. Fusaro, Rochelle A. Sturtevant, Edward S. Rutherford, Donna R. Kashian

Biological Sciences Faculty Research Publications

A thorough assessment of aquatic nonindigenous species’ risk facilitates successful monitoring and prevention activities. However, species- and vector-specific information is often limited and difficult to synthesize across a single risk framework. To address this need, we developed an assessment framework capable of estimating the potential for introduction, establishment, and impact by aquatic nonindigenous species from diverse spatial origins and taxonomic classification, in novel environments. Our model builds on previous approaches, while taking on a new perspective for evaluation across species, vectors and stages to overcome the limitations imposed by single species and single vector assessments. We applied this globally-relevant framework …

Detritus Quality And Locality Determines Survival And Mass, But Not Export, Of Wood Frogs At Metamorphosis, Joseph Milanovich, Kyle Barrett, John A. Crawford

Biology: Faculty Publications and Other Works

Single-site experiments have demonstrated detritus quality in wetlands can have strongly negative, neutral, and even positive influences on wildlife. However, an examination of the influence of detritus quality across several regions is lacking and can provide information on whether impacts from variation in detritus quality are consistent across species with wide ranges. To address this gap in regional studies we examined effects of emergent and allochthonous detritus of different nutrient qualities on amphibians and assessed a mechanism that may contribute to potential impacts. We used aquatic mesocosms to raise wood frogs (Rana sylvatica) from two regions of the …

Use Of A Modified Greenscreen Tool To Conduct A Screening-Level Comparative Hazard Assessment Of Conventional Silver And Two Forms Of Nanosilver., Jennifer Sass, Lauren Heine, Nina Hwang

Environmental and Occupational Health Faculty Publications

BACKGROUND: Increased concern for potential health and environmental impacts of chemicals, including nanomaterials, in consumer products is driving demand for greater transparency regarding potential risks. Chemical hazard assessment is a powerful tool to inform product design, development and procurement and has been integrated into alternative assessment frameworks. The extent to which assessment methods originally designed for conventionally-sized materials can be used for nanomaterials, which have size-dependent physical and chemical properties, have not been well established. We contracted with a certified GreenScreen profiler to conduct three GreenScreen hazard assessments, for conventional silver and two forms of nanosilver. The contractor summarized publicly …

Neurovascular integrity plays an important role in protecting cognitive and mental health in aging. Lifestyle interventions that sustain neurovascular integrity may thus be critical on preserving brain functions in aging and reducing the risk for age-related neurodegenerative disorders. Here we show that caloric restriction (CR) had an early effect on neurovascular enhancements, and played a critical role in preserving vascular, cognitive and mental health in aging. In particular, we found that CR significantly enhanced cerebral blood flow (CBF) and blood-brain barrier function in young mice at 5-6 months of age. The neurovascular enhancements were associated with reduced mammalian target of …

Entomology Faculty Publications

The development of genetically engineered plants that employ RNA interference (RNAi) to suppress invertebrate pests opens up new avenues for insect control. While this biotechnology shows tremendous promise, the potential for both non-target and off-target impacts, which likely manifest via altered mRNA expression in the exposed organisms, remains a major concern. One powerful tool for the analysis of these un-intended effects is reverse transcriptase-quantitative polymerase chain reaction, a technique for quantifying gene expression using a suite of reference genes for normalization. The seven-spotted ladybeetle Coccinella septempunctata, a commonly used predator in both classical and augmentative biological controls, is a …

Effects Of Antibiotic Mixtures Across Marine Intertidal Trophic Levels: Examining Environmentally-Relevant Contaminant Concentrations, Jaclyn Rebecca Teixeira

Dissertations and Theses

Approximately 48% of Americans use prescription drugs within each 30-day period, and there are signs this trend is increasing. Although many studies track pharmaceuticals’ fates in contaminating waterways, only fairly recent efforts have examined the potential impacts of these drugs on non-target organisms. The antibiotics sulfamethoxazole and trimethoprim, often prescribed together to treat bacterial infections, have been detected worldwide in marine and estuarine environments at concentrations up to 700-800 ng/L each. Toxic effects of these drugs have been identified in freshwater organisms, with synergistic effects observed in short-term studies of mixtures of the two; however, little research has examined possible …

Aquaponics is a sustainable food production system that combines hydroponic plant growth with fish rearing in a recirculating aquaculture system. Nile tilapia (Oreochromis niloticus) are predominantly raised in aquaponics due to their fast growth rates and ability to tolerate a variety of water conditions. As aquaponics becomes more popular in temperate climate zones, farmers are looking for alternative fish species that are more compatible with cooler temperatures and have a higher market value than tilapia. Authors will determine if plant growth factors as well as, the availability of nutrients in aquaponic systems are affected by the difference in nutrient requirements …

Early Nutritional Programming To Enhance The Utilization Of Plant Based Diets In Fish (Largemouth Bass, Micropterus Salmoides), Maya Rene Jackson, Cora Teets, Amit Kumar Yadav, Waldemar Rossi

Posters-at-the-Capitol

Aquaculture has been the fastest growing animal food-producing sector for over half a century. Sustainable aquaculture should include replacement of fish-based feed sources by plant-based ingredients. However, this approach is often impeded by poor growth in carnivorous fish such as largemouth bass (LMB, Micropterus salmoides) fed high levels of plant-based protein. Therefore, our overall goal of the present work was to develop alternative methods of utilizing the plant-based diets (PBD) for sustainable LMB production. When fish is exposed to PBD early in their life, they may accept them more efficiently at later stages (so called Nutritional Programing, NP). Therefore, …

Abstract

Environmental challenges shape the evolution of animal behavior and morphology. For wingless terrestrial invertebrates like ants, pools of water on the forest floor are particularly dangerous. Here we show that ants can overcome this obstacle using a modified gait to transverse the water surface. We compared the locomotor morphology and swimming performance of two arboreal ant species that are common in Kentucky (Camponotus pennsylvanicus and Formica subsericea). We defined performance as speed …
