Plasmodium Falciparum Infection Increases Anopheles Gambiae Attraction To Nectar Sources And Sugar Uptake, Vincent O. Nyasembe, Peter E.A. Teal, Patrick Sawa, James H. Tumlinson, Christian Borgemeister, Baldwyn Torto

All Peer-Reviewed Publications

Plasmodium parasites are known to manipulate the behavior of their vectors so as to enhance transmission [1-4]. From an evolutionary standpoint, behavior manipulation by the parasite should expose the vector to limited risk of early mortality while ensuring sufficient energy supply for both it and the vector [5, 6]. However, it is unknown whether this vector manipulation also affects vector-plant interaction and sugar uptake. Here, we show that the attraction of Anopheles gambiae s.s. to plant odors increased by 30% and 24% after infection with the oocyst and sporozoite stages of Plasmodium falciparum, respectively, while probing activity increased by 77% …

Optimization Of Wind Turbine Airfoils/Blades And Wind Farm Layouts, Xiaomin Chen

All Theses and Dissertations (ETDs)

Shape optimization is widely used in the design of wind turbine blades. In this dissertation, a numerical optimization method called Genetic Algorithm (GA) is applied to address the shape optimization of wind turbine airfoils and blades. In recent years, the airfoil sections with blunt trailing edge (called flatback airfoils) have been proposed for the inboard regions of large wind-turbine blades because they provide several structural and aerodynamic performance advantages. The FX, DU and NACA 64 series airfoils are thick airfoils widely used for wind turbine blade application. They have several advantages in meeting the intrinsic requirements for wind turbines in …

Biochemical Analysis Of Blood Of Native Cattle In The Hilly Area Of Bangladesh, M. A. Mamun, M. M. Hassan, A. H. Shaikat, S.K.M.A. Islam, M. A. Hoque, M. Uddin, M. B. Hossain

Biochemistry Collection

A yearlong study was carried out in indigenous cattle of five upazila namely Khagrachari Sadar, Laxmichari, Matiranga, Mahalchari and Dighinala in Khagrachari Hill District, Bangladesh for determination of statuses of various biochemical parameters. Apparently healthy cattle (100) were selected and blood samples were collected aseptically. Biochemical analysis of carbohydrates, proteins, fats, minerals, electrolytes and enzymes were performed by using automated biochemical analyzer (Humalizer®-3000). The results showed that, the variations of parameters were not significant (P>0.05) between male and female. Although there was a slight increase of calcium 8.01±0.32mg/dl, glucose 69.21±2.31mg/dl, LDL 5.69±0.22mg/dl and uric acid 3.85±0.34mg/dl of female compared …

Effectiveness Of Rodenticides For Managing Invasive Roof Rats And Native Deer Mice In Orchards, Roger A. Baldwin, Niamh Quinn, David H. Davis, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Roof rats (Rattus rattus) and deer mice (Peromyscus maniculatus) are occasional pests of nut and tree fruit orchards throughout California and in many other parts of the USA and beyond. In general, the most practical and cost-effective control method for rodents in many agricultural environments is the use of rodenticides (toxic baits), but little or no information exists on the efficacy of current rodenticides in controlling roof rats and deer mice in orchards. Therefore, our goals were to develop an index of rodent activity to monitor efficacy of rodenticides and to subsequently test the efficacy of three California Department of …

Red Meat And Our Health: Separating Scientific Fact From Politics, Emotion And Misinformation, Peter Ballerstedt

Forage Symposium at the Kentucky Cattlemen’s Convention

The 2010 Dietary Guidelines for Americans recommends restricting our intake of saturated fat to less than 7 percent of calories, and our cholesterol intake to less than 300 mg per day (less than two eggs). They promote the use of low-fat milk and lean meat, and the use of “meat substitutes” in school lunches. These recommendations are consistent with the official dietary policy that began in 1977 with the release of the first Dietary Goals for the United States by the United States Senate Select Committee on Nutrition and Human Needs. These guidelines were not justified by the then-available science. …

Animal Welfare--Animal Rights: "Protecting Animals Or A Threat To U.S. Food Production And Our Way Of Life?", W. Roy Burris

How Much Is Enough? Minimal Responses Of Water Quality And Stream Biota To Partial Retrofit Stormwater Management In A Suburban Neighborhood, Allison H. Roy, Lee K. Rhea, Audrey L. Mayer, William D. Shuster, Jake J. Beaulieu, Matthew E. Hopton, Matthew A. Morrison, Ann St. Amand

College of Forest Resources and Environmental Science Publications

Decentralized stormwater management approaches (e.g., biofiltration swales, pervious pavement, green roofs, rain gardens) that capture, detain, infiltrate, and filter runoff are now commonly used to minimize the impacts of stormwater runoff from impervious surfaces on aquatic ecosystems. However, there is little research on the effectiveness of retrofit, parcel-scale stormwater management practices for improving downstream aquatic ecosystem health. A reverse auction was used to encourage homeowners to mitigate stormwater on their property within the suburban, 1.8 km² Shepherd Creek catchment in Cincinnati, Ohio (USA). In 2007–2008, 165 rain barrels and 81 rain gardens were installed on 30% of the properties …

Effect Of Chronic Thoracic Spinal Cord Injury (Sci) On The Peripheral Immune System In Mice, Ji Zha

Open Access Dissertations

Patients with chronic spinal cord injury (SCI) are at higher risk than the general population of developing infections and their prognosis is often much poorer. The disruption of the normal balance between central nervous system and immune system following SCI induces immunodepression, leading to a compromised capacity to combat infections such as influenza virus in patients with SCI. Using a contusion model of SCI at thoracic level 9, we analyzed the chronic effect of SCI on the peripheral immune system in mice, with a focus on T-cell immunity. We found that although the splenic T-cell number was not changed during …

Studies On Theraputic Potential Of Dichloroacetic Acid And Hene Laser In Cancer Treatment: Understanding The Mechanism Of Action, Zeiyad Nassaif Al-Karakooly

Theses and Dissertations

Cancer cells are often characterized by anaerobic glycolysis due to dysfunctional mitochondria that limits pyruvate uptake for aerobic respiration. Dichloroacetic acid (DCA), used in this study as a potential cancer treatment agent, targets mitochondria in cancer cells and is likely to correct mitochondrial dysfunction by resuming pyruvate uptake and therefore normal aerobic respiration. Our results suggest that DCA causes a significantly higher cytotoxicity in aggressive MCF-7 breast cancer cells than in non-aggressive MC3T3 osteoblastic cells. Apparently lower doses of DCA induce apoptosis whereas higher doses lead to non-specific cytotoxicity or necrosis. Increased cytotoxicity might be related to oxidative stress due …

Modeling Of Ice Algal And Pelagic Production And Air-Sea Co2 Exchange In The Arctic Ocean, Meibing Jin

Research Posters

In the Arctic Ocean, both phytoplankton and sea ice algae are important contributors to the primary production and the arctic food web. Copepod in the arctic regions have developed their feeding habit depending on the timing between the ice algal bloom and the subsequent phytoplankton bloom. A mismatch of the timing due to climate changes could have dramatic consequences on the food web as shown by some regional observations. In this study, a global coupled ice- ocean-ecosystem model was used to assess the seasonality of the ice algal and phytoplankton blooms in the arctic. The ice-ocean ecosystem modules are fully …

Autobiography, Biography, And Narrative Ethics, Lev Y. Yampolsky, Michael A. Bouzinier

ETSU Faculty Works

Background: Duplicated genes can indefinately persist in genomes if either both copies retain the original function due to dosage benefit (gene conservation), or one of the copies assumes a novel function (neofunctionalization), or both copies become required to perform the function previously accomplished by a single copy (subfunctionalization), or through a combination of these mechanisms. Different models of duplication retention imply different predictions about substitution rates in the coding portion of paralogs and about asymmetry of these rates. Results: We analyse sequence evolution asymmetry in paralogs present in 12 Drosophila genomes using the nearest non-duplicated orthologous outgroup as a reference. …

"What Does This Graph Mean?" Formative Assessment With Science Inquiry To Improve Data Analysis, Andrea Dawn Leech

Dissertations and Theses

This study investigated the use of formative assessment to improve three specific data analysis skills within the context of a high school chemistry class: graph interpretation, pattern recognition, and making conclusions based on data. Students need to be able to collect data, analyze that data, and produce accurate scientific explanations (NRC, 2011) if they want to be ready for college and careers after high school. This mixed methods study, performed in a high school chemistry classroom, investigated the impact of the formative assessment process on data analysis skills that require higher order thinking. We hypothesized that the use of evaluative …

Effects Of Ethnicity And Gender On Sixth-Grade Students' Environmental Knowledge And Attitudes After Participation In A Year-Long Environmental Education Program, Rachel Stagner

Dissertations and Theses

The goal of environmental education (EE) has always been to increase knowledge about the environment and to foster positive environmental attitudes. Increasingly, as the call for integrating EE programs into mainstream science curriculum intensifies, it is important to continue to evaluate the effectiveness of these programs not only through measures of change in knowledge and attitudes, but through the additional criteria of meeting the needs of different gender and ethnic groups.

The purpose of this research was to identify whether a watershed education program was meeting the needs of diverse learners within the context of a year-long, integrated, sixth-grade science …

Self-Efficacy In Low-Level English Language Learners, Laura F. Blumenthal

Dissertations and Theses

Accounting for differences in second language proficiency attainment is an important area of inquiry in the study of Second Language Acquisition (SLA). Accounts of the language acquisition process have generally come from cognitive or psychological perspectives, which view language learning as primarily an internal mental/emotional process, or from sociocultural or critical perspectives that emphasize the influence of the learner's social environment. Research on variability in language learning has also failed to take into account the learning experiences of low-level learners.

This study adopted a social-psychological perspective on language acquisition that focused on the role of self-efficacy in learning, and applied …

Machine Learning Approaches To Transcription Factor Binding Site Search And Visualization, Chih Lee

Doctoral Dissertations

A transcription factor (TF) is a protein or protein complex. It regulates the expression of its target genes by physically binding to the regulatory regions of these genes. The binding sites of a TF naturally share a common pattern or motif with one another. Given known binding sites of a TF, a TF model can be built to scan sequences for putative binding sites. This is known as a transcription factor binding site (TFBS) search problem. In this dissertation, we investigate the TFBS search problem using machine learning approaches.

In general, the known binding sites of a TF are of …

An Imaging-Based Platform For High-Content, Quantitative Evaluation Of Therapeutic Response In 3d Tumour Models, Jonathan P. Celli, Imran Rizvi, Adam R. Blanden, Iqbal Massodi, Iqbal Massodi, Michael D. Glidden, Brian Pogue, Tayyaba Hasan

Dartmouth Scholarship

While it is increasingly recognized that three-dimensional (3D) cell culture models recapitulate drug responses of human cancers with more fidelity than monolayer cultures, a lack of quantitative analysis methods limit their implementation for reliable and routine assessment of emerging therapies. Here, we introduce an approach based on computational analysis of fluorescence image data to provide high-content readouts of dose-dependent cytotoxicity, growth inhibition, treatment-induced architectural changes and size-dependent response in 3D tumour models. We demonstrate this approach in adherent 3D ovarian and pancreatic multiwell extracellular matrix tumour overlays subjected to a panel of clinically relevant cytotoxic modalities and appropriately designed controls …

Mechanical And Microscopic Properties Of The Reversible Plastic Regime In A 2d Jammed Material, Nathan C. Keim, Paulo E. Arratia

Physics

At the microscopic level, plastic flow of a jammed, disordered material consists of a series of particle rearrangements that cannot be reversed by subsequent deformation. An infinitesimal deformation of the same material has no rearrangements. Yet between these limits, there may be a self-organized plastic regime with rearrangements, but with no net change upon reversing a deformation. We measure the oscillatory response of a jammed interfacial material, and directly observe rearrangements that couple to bulk stress and dissipate energy, but do not always give rise to global irreversibility.

Fabrication Of Cds Nanoparticle Coated Jasmonate Conjugates And Their Interactions With Mammalian Cells, Nazmul Sarker Fcrh '13, Stacey Barnaby Fcrh '11, Ipsita Bannerjee

The Fordham Undergraduate Research Journal

In this work, we have grown CdS nanoparticles on jasmonate nanoassemblies biomimetically and examined their interactions with mammalian cells. In general, plants naturally secrete the phytohormone jasmonic acid during development and in response to biotic and abiotic stress as a defense mechanism (Traw and Bergelson 2003; Sembdner and Parthier 1993). We have developed a new class of nanomaterials by utilizing nanoassemblies of the plant phytohormone jasmonic acid (JA) as templates for the growth of quantum dots, which may have potential applications as sensors and may potentially be utilized for bioimaging applications.

Algebraic Detection Of Flexibility Of Polyhedral Structures With Applications To Robotics And Chemistry, Stephen Fox Fcrh '11, Robert Lewis

The Fordham Undergraduate Research Journal

Many problems arise in biochemistry, robotics, and other fields in which flexibility of a polygonal or polyhedral structure plays an important role. In biochemistry, the flexibility and folding of molecules is an important factor in drug design and is a subject of ongoing research (Erickson et al. 2004). In robotics, stable configurations of manipulators (e.g., a mechanical arm grasping) as well as mechanical joints for locomotion (e.g., walking) must be calculated for safe, smooth movement.
