Preparation Of Nanoprobes And Their Possible Applications In Nanoscale Scanning Electrochemical Microscopy For Studying Electrocatalytic Oxygen And Hydrogen Reactions, Xing-Xing Chen

Journal of Electrochemistry

Scanning electrochemical microscopy (SECM) is a type of scanning probe microscopy, which can not only provide the topographical information, but also offer the electrochemical properties of different samples. The interrelationship of physical and electrochemical properties of a sample can be searched at a high-resolution scale due to the introduction of ultramicroelectrode (UME). With the continuous development of modern nanotechnology, the SECM probe has been improved with drastically decreasing its size down to nanometer. Meanwhile, to evaluate and understand the electrochemical performance of various electrocatalysts for both oxygen and hydrogen reactions with high-efficiency is highly demanded in the research area of …

Wildland Resources Faculty Publications

Demonstrating disease impacts on the vital rates of free‐ranging mammalian hosts typically requires intensive, long‐term study. Evidence for chronic pathogens affecting reproduction but not survival is rare, but has the potential for wide‐ranging effects. Accurately quantifying disease‐associated reductions in fecundity is important for advancing theory, generating accurate predictive models, and achieving effective management. We investigated the impacts of brucellosis (Brucella abortus) on elk (Cervus canadensis) productivity using serological data from over 6,000 captures since 1990 in the Greater Yellowstone Ecosystem, USA. Over 1,000 of these records included known age and pregnancy status. Using Bayesian multilevel models, …

Does An(Y) Order Exist Within The Structural Art, Feti Selmani

UBT International Conference

Many authors have treated the beauty and aesthetics from the social and phylosofic point of view [Kant, Plato], whereas very few of them have meditated within the domain of Architecture let alone Structural Engineering [Leonhardt]. The Beautiful is beautiful, and the Ugly is ugly, but subjectivity apart, is any mean of defining a way or some Principles which can be of Guide for the designer. Is there any mathematics within the beauty, i.e., can the beauty be described in a mathematical way. It is a simple, yet a very difficult question answering, since both the beauty and aesthetics falls into …

Interaction Of Nanofibers With Epithelial Cells In The Digestive System, Agron Millaku

UBT International Conference

In this study, we provide the evidence of interaction of tungsten nanofibres (NF- WOx) with epithelial cells in the digestive tube of a test organism, woodlouse Porcellio Scaber studied by scanning electron microscopy (SEM). When the nanofibers enter the body through food, not all of them pass through the digestive system, without an interaction with the epithelial cells. The result has provided us that in some areas nanofibers can react with epithelial cells on the digestive tube very fast. The images which were taken in the treated samples through scanning electron microscopy and energy dispersive spectroscopy analysis clearly show such …

Department of Nutrition and Health Sciences: Faculty Publications

Background: The tetracycline-responsive system (Tet-ON/OFF) has proven to be a valuable tool for manipulating gene expression in an inducible, temporal, and tissue-specific manner. The purpose of this study was to create and characterize a new transgenic mouse strain utilizing the human skeletal muscle α-actin (HSA) promoter to drive skeletal muscle-specific expression of the reverse tetracycline transactivator (rtTA) gene which we have designated as the HSA-rtTA mouse. Methods: To confirm the HSA-rtTA mouse was capable of driving skeletal muscle-specific expression, we crossed the HSA-rtTA mouse with the tetracycline-responsive histone H2B-green fluorescent protein (H2B-GFP) transgenic mouse in order to label myonuclei. Results: …

On Continuum Beliefs And Psychiatric Stigma: Similarity To A Person With Schizophrenia Can Feel Too Close For Comfort, Ryan Thibodeau, Karlie M. Peterson

Psychology Faculty/Staff Publications

Continuum belief interventions that blur boundaries between “normal” individuals and individuals with psychiatric problems have shown promise in reducing psychiatric stigma. Interventions to date have afforded participants considerable psychological distance from individuals with mental illness. An intervention that compels psychological closeness to individuals with mental illness may lead to increased anxiety/threat and an attenuated intervention effect on stigma. In a randomized experiment, one hundred thirty-five participants listened to a bogus interview involving an ostensible person with schizophrenia who shared numerous characteristics in common with participants. In the interview, the target person (1) did not verbally broach issues of similarity to …

Review Of Methods For Intraoperative Margin Detection For Breast Conserving Surgery, Benjamin W. Maloney, David M. Mcclatchy, Brian W. Pogue, Keith D. Paulsen, Wendy A. Wells, Richard J. Barth

Dartmouth Scholarship

Breast conserving surgery (BCS) is an effective treatment for early-stage cancers as long as the margins of the resected tissue are free of disease according to consensus guidelines for patient management. However, 15% to 35% of patients undergo a second surgery since malignant cells are found close to or at the margins of the original resection specimen. This review highlights imaging approaches being investigated to reduce the rate of positive margins, and they are reviewed with the assumption that a new system would need high sensitivity near 95% and specificity near 85%. The problem appears to be twofold. The first …

Publications

PURPOSE: Lifestyle factors associated with personal behavior can alter tumor-associated biological pathways and thereby increase cancer risk, growth, and disease recurrence. Advanced glycation end products (AGEs) are reactive metabolites produced endogenously as a by-product of normal metabolism. A Western lifestyle also promotes AGE accumulation in the body which is associated with disease phenotypes through modification of the genome, protein crosslinking/dysfunction, and aberrant cell signaling. Given the links between lifestyle, AGEs, and disease, we examined the association between dietary-AGEs and breast cancer. METHODS: We evaluated AGE levels in bio-specimens from estrogen receptor-positive (ER+) and estrogen receptor-negative (ER-) breast cancer patients, examined …

Sleep Disorders In Children With Autism Spectrum Disorder: A Pilot Study Of An Assessment Of Pediatric Providers' Practices And Perceptions, Kristin Lynn Edwards

USF Tampa Graduate Theses and Dissertations

Children with Autism Spectrum Disorder (ASD) have increased rates for sleep problems compared with typically developing children. Although physicians practicing in pediatric primary care settings have the potential to detect and address sleep problems at an early age, research investigating the sleep management practices of pediatricians in primary care is scant and does not particularly address children with ASD. This study investigated the frequency of sleep screening measures utilized by pediatric providers during well-child examinations, the most frequently recommended treatments, the barriers and facilitators to screening for sleep problems, and the perceived confidence of pediatricians with regard to screening for …

Bacterial Contamination Of Platelets For Transfusion: Strategies For Prevention., Jerrold H. Levy, Matthew D. Neal, Jay H. Herman

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Platelet transfusions carry greater risks of infection, sepsis, and death than any other blood product, owing primarily to bacterial contamination. Many patients may be at particular risk, including critically ill patients in the intensive care unit. This narrative review provides an overview of the problem and an update on strategies for the prevention, detection, and reduction/inactivation of bacterial contaminants in platelets. Bacterial contamination and septic transfusion reactions are major sources of morbidity and mortality. Between 1:1000 and 1:2500 platelet units are bacterially contaminated. The skin bacterial microflora is a primary source of contamination, and enteric contaminants are rare but may …
