The light-driven photocycle of rhodopsin begins the photoreceptor cascade that underlies visual response. In a sequence of events, the retinal covalently attached to the rhodopsin protein undergoes a conformational change that communicates local changes to a global conformational change throughout the whole protein. In turn, the large-scale protein change(More)
Little is known about the nature of the microbiology in tap waters delivered to consumers via public drinking water distribution systems (DWDSs). In order to establish a broader understanding of the microbial complexity of public drinking waters we sampled tap water from seventeen different cities between the headwaters of the Arkansas River and the mouth(More)
The goal of this study was to determine the composition and diversity of microorganisms associated with bioaerosols in a heavily trafficked metropolitan subway environment. We collected bioaerosols by fluid impingement on several New York City subway platforms and associated sites in three sampling sessions over a 1.5-year period. The types and quantities(More)
RATIONALE Oropharyngeal (OP) swabs and induced sputum (IS) are used for airway bacteria surveillance in nonexpectorating children with cystic fibrosis (CF). Molecular analyses of these airway samples detect complex microbial communities. However, the optimal noninvasive sampling approach for microbiota analyses and the clinical relevance of microbiota,(More)
Personality traits were examined in relation to job satisfaction and career satisfaction for 1059 information technology (IT) professionals. As hypothesized, eight traits were significantly related to both job and Regression analyses indicated that sets of three and four traits accounted for 17 and 25%, respectively, of job and career satisfaction variance.(More)
BACKGROUND This study determined the prevalence, types, and attitudes towards complementary and alternative medicines (CAMs) and therapies in cancer patients actively undergoing conventional cancer treatment at a regional cancer centre. METHODS Data were collected using a self-administered questionnaire provided to adult cancer patients attending a(More)
We present coarse-grained simulations of fusion between two liposomes from which a detailed picture of lipid movements emerges. In these simulations the bilayers dilate at the contact edge, and the resulting increase in the area per lipid produces a tilting of the individual molecules as predicted. Fusion is initiated when some of these tilted lipids splay(More)
A minimal model of lipid molecules consisting of bead-spring representation is developed. The basic interactions are hydrophobic and polar interactions. Essential physical features of lipid bilayers are maintained using this model, and relatively long times can be simulated in comparison to atomistic models. Self-assembly from a random starting(More)
Phragmatopoma Californica builds a tubular dwelling by gluing bits of sand and seashell together underwater with a proteinaceous adhesive. In the lab, the animals will build with 0.5 mm glass beads. Two spots of glue with a consistent volume of about 100 pL each are deposited on the glass beads before placement on the end of the tube. The animals wriggled(More)
The composition and metabolic activities of microbes in drinking water distribution systems can affect water quality and distribution system integrity. In order to understand regional variations in drinking water microbiology in the upper Ohio River watershed, the chemical and microbiological constituents of 17 municipal distribution systems were assessed.(More)
