Liver disease of different etiologies confers significant morbidity and mortality and hence it constitutes a major health concern worldwide. Stemming from a range of causes, such as viral, drug-induced, alcoholic, or autoimmune, the rate of...
Pseudomonas aeruginosa is the leading cause of morbidity and mortality amongst cystic fibrosis (CF) patients. Following initial colonization of the CF lung by P. aeruginosa , the bacterium establishes chronic, long-term infections. Chronic P....
Autoimmune hepatitis (AIH) is an autoimmune liver disease characterized by immune-mediated necroinflammatory liver damage associated with CD4 + T cell infiltration in liver parenchyma. Despite advances in the understanding of AIH, its etiology...
Behavior during interracial contact is sometimes positive but often negative. Previous work has examined individual differences, such as racial attitudes and motivations to respond without prejudice, as predictors of behavior during interracial...
As the visual effect and movie industries are striving for realism and high fidelity images, physically based lighting, global illumination, realistic materials, and highly tessellated geometry are gradually accepted and used in movie and game...
Yeast vacuole fusion involves three transmembrane SNAREs and a unique soluble SNARE, Vam7p. This SNARE cycles between vacuolar membrane-bound and cytosolic state. In its membrane-bound state, it is able to participate in vacuolar fusion by...
Pseudomonas aeruginosa is a virulent opportunistic pathogen that is frequently cultured from infectious sites, and is estimated to cause ~12% of nosocomial infections worldwide [1]. P. aeruginosa infections occur in a majority of adults with the...
A fundamental question in decision neuroscience is how cognitive processes underlying decision-making give rise to efficient decisions, especially in complex situations with multiple choice options, and each option consisting of multiple attributes...
Quantitative Risk Analysis of Computer Networks (QSRA) addresses the problem of risk opacity of software in networks. It allows risk managers to get a detailed and comprehensive snapshot of the constitutive software on the network, assess its risk...
Prion diseases are fatal neurodegenerative disorders which affect a variety of different animal species including humans. The central pathogenic event underlying prion diseases is the conformational conversion of the cellular prion protein (PrP C )...
Every moment of our waking lives, our brains filter large quantities of sensory data for goal relevant information. This ability to modulate our sensitivity to incoming inputs is critical in the face of an otherwise overwhelming world, and...
Proper chromosome alignment and segregation depends on the formation and maintenance of a bipolar mitotic spindle with focused poles. It has been shown that microtubules are focused at spindle poles through the combined actions of centrosomes and a...
The brain is a vastly interconnected information processing network. In humans, this network supports the rich mental space at the root of the imagination and enables many flexible cognitive abilities such as scientific and artistic creativity. How...
Aneuploidy is frequently detected in human cancers and is implicated in carcinogenesis. Pharmacological targeting of aneuploidy is an attractive therapeutic strategy, as this would preferentially eliminate malignant over normal cells. Our prior...
Humans have a seemingly unique capacity to reflect upon information about the self to form evaluative attitudes that influence their quality of life and predict mental health outcomes. While psychologists have devoted decades of research to the...
Developmental prosopagnosia (DP) is a neurodevelopmental disorder defined by impaired face recognition in the absence of brain damage, low-level visual deficits, or broad cognitive problems. Behavioral and neural findings suggest different types of...
Visual pigments. ; Cellular signal transduction. ; Rhodopsin. ; G proteins. ; Phosphorylation. ; Photoreceptors. ; Retinal degeneration.
Arrestins are regulatory proteins that participate in the termination of G protein-mediated signal transduction. The major arrestin in the Drosophila visual system, Arrestin 2 (Arr2), has been demonstrated to be essential for the termination of the...
Plasma instabilities. ; Ionospheric electron density. ; Ionosphere.
As a result of an unstable plasma stratification the nighttime equatorial ionosphere is subject to a variety of plasma instabilities known commonly as equatorial spread-F. In its fully developed form spread-F consists of large wedges of depleted...
Congenital heart disease in children -- Surgery -- Evaluation. ; Heart -- Abnormalities -- Surgery -- Evaluation. ; Outcome assessment (Medical care).
Hypoplastic left heart syndrome (HLHS) is a heart malformation that requires surgical intervention for survival. Without surgery, 95% of neonates with HLHS die in the first month of life. Two surgical approaches are available, a series of...
Clinical medicine -- Practice. ; Medicine -- Practice. ; Group medical practice.
Health care micro-systems are small, organized groups of clinicians and staff working together with a shared clinical purpose to provide care for a defined set of patients. The size of individual micro-systems vary--a micro-system must be large...
Chromium -- Toxicity testing. ; Glutathione. ; Vitamin C -- Physiological effect. ; Carcinogenesis. ; DNA damage.
Chromium(VI) is a human carcinogen and causes DNA damage following reduction by intracellular reductants. In order to explore the effects of intracellular reductants on the carcinogenicity of Cr(VI), the roles of glutathione and ascorbate in...
This research has established feasibility of surface temperature characterization using ruby fluorescence. Study was performed in pin-on-disk geometry, with balls made of different plastics sliding against the sapphire disk. Fluorescence signal was...
Protein kinase C activators and microtubule damaging drugs stimulate BCL2 phosphorylation, which has been associated with either enhancement or inhibition of cell viability. In a Burkitt lymphoma cell line, both types of agents likewise stimulated...
Cellulase -- Biotechnology. ; Hydrolysis. ; Paper industry -- Technological innovations. ; Biomass energy -- Economic aspects. ; Saccharomyces cerevisiae -- Genetics. ; Enzymes -- Industrial applications.
Paper sludge is the largest solid waste stream produced by pulp and paper industry, and is also an attractive feedstock for emergent technologies based on processing of cellulosic biomass featuring enzymatic hydrolysis. This study focuses on...
Digital cinematography. ; Cinematography -- Lighting -- Data processing -- Evaluation. ; Cinematography -- Special effects -- Data processing -- Evaluation. ; User interfaces (Computer systems) -- Evaluation.
We define appearance design as the creation and editing of scene content such as lighting and surface materials in computer graphics. The appearance design process takes a significant amount of time relative to other production tasks and poses...
Arabidopsis thaliana -- Genetics. Transcription factors. Iron -- Metabolism. Iron deficiency diseases in plants -- Genetic aspects.
In order to preserve a balance between the requirement for iron and its toxicity, plants likely maintain tight control over iron homeostasis. We are interested in identifying factors involved in the regulation of iron uptake and have examined this...
Microtubule motors are essential for cell division. Although the functions of some mitotic motor proteins have been elucidated, the precise mechanisms by which they govern spindle assembly and chromosome segregation remain largely unknown. This...
