Global patterns of diversity and community structure in marine bacterioplankton
Because of their small size, great abundance and easy dispersal, it is often assumed that marine planktonic microorganisms have a ubiquitous distribution that prevents any structured assembly into local communities. To challenge this view, marine bacterioplankton communities from coastal waters at nine locations distributed world-wide were examined through the use of comprehensive clone libraries
Clinical efficacy and pharmacokinetic profiles of intranasal and oral cetirizine in a repeated allergen challenge model of allergic rhinitis.
Background: Intranasal and oral antihistamines are effective in treating allergic rhinitis. Studies comparing these routes of administration of an antihistamine regarding efficacy and pharmacokinetic profile are lacking. Objective: To compare topical and oral routes of administration of cetirizine regarding efficacy, plasma exudation, and systemic drug levels in a repeated allergen challenge model
Quantum chemistry predicts multiply bonded diuranium compounds to be stable
Results from quantum chemical calculations that predict the existence of a series of diuranium molecules are reported. Two diuranium chlorides, U2Cl6 and U2Cl82-, and three different carboxylates, U-2(OCHO)(4), U-2(OCHO)(6), and U-2(OCHO)(4)Cl-2 have been studied. All species have been found to be stable with a multiply bonded U-2 unit.
Content validity and clinical applicability of the Irena Daily Activity assessment measuring occupational performance in adults with developmental disability
The purpose of this study was to investigate the validity of the Irena Daily Activity (IDA) assessment which measures occupational performance in adults with developmental disabilities. The instrument's content validity was investigated by elucidating its general appropriateness, its clinical applicability and the feasibility of the measurement procedure. Data were collected from a multidisciplina
The IFCC reference measurement system for HbA(1)C: A 6-year progress report
BACKGROUND: The IFCC Reference Measurement System for hemoglobin (Hb)A(1)c (IFCC-RM) has been developed within the framework of metrologic traceability and is embedded in a network of 14 reference laboratories. This paper describes the outcome of 12 intercomparison studies (periodic evaluations to control essential elements of the IFCC-RM). METHODS: Each study included: unknown samples (to test in
Natural history and outcome in 32 Swedish patients with small duct primary sclerosing cholangitis (PSC)
Background/Aims: This study aims at describing the natural history and outcome of small duct primary sclerosing cholangitis (PSC). Methods: Thirty-two patients with small duct PSC were studied. The average time taken for diagnosis was 69 (1-168) months. The median follow-up time was 63 (1-194) months. Results: All patients including one who underwent liver transplantation because of end-stage live
The Blend station - a new ratio control structure
The paper treats the problem of ratio control. Previous solutionsbased on simple Ratio stations perform poorly during transientscaused by setpoint changes. A new solution, the Blend station, thatimproves control during transients, is proposed. Both a constant-gainand an adaptive version are presented.
Biglycan organizes collagen VI into hexagonal-like networks resembling tissue structures.
The ability of the leucine-rich repeat (LRR) proteins biglycan, decorin and chondroadherin to interact with collagen VI and influence its assembly to supramolecular structures was studied by electron microscopy and surface plasmon resonance measurements in the BIAcore 2000 system. Biglycan showed a unique ability to organize collagen VI into extensive hexagonal-like networks over a time period of
Racemic ketamine does not abolish cerebrovascular autoregulation in the pig.
Background: Little is known about the influence of racemic ketamine on autoregulation of cerebral blood flow (CBF), and available reports regarding its influence on cerebral hemodynamics are contradictory. This study was designed to evaluate cerebrovascular responses to changes in the mean arterial pressure (MAP) during ketamine anesthesia. Methods: In eight normoventilated pigs anesthesia was in
Modular name analysis for Java using JastAdd
Name analysis for Java is challenging with its complex visibility rules involving nested scopes, inheritance, qualified access, and syntactic ambiguities. We show how Java name analysis including ambiguities related to names of variables, fields, and packages, can be implemented in a declarative and modular manner using the JastAdd compiler construction system. Declarative attributes and context-d
Smad5 is dispensable for adult murine hematopoiesis.
Smad5 is known to transduce intracellular signals from bone morphogenetic proteins (BMPs), which belong to the transforming growth factor-beta (TGF-beta) superfamily and are involved in the regulation of hematopoiesis. Recent findings suggest that BMP4 stimulates proliferation of human primitive hematopoietic progenitors in vitro, while early progenitors from mice deficient in Smad5 display increa
Titanium dioxide thin-film growth on silicon(111) by chemical vapor deposition of titanium(IV) isopropoxide
The initial stages of TiO2 growth on Si(111) under ultra-high vacuum conditions is studied using core level photoelectron spectroscopy, x-ray absorption spectroscopy, and scanning tunneling microscopy. The TiO2 film was formed by means of chemical vapor deposition of titanium(IV) isopropoxide at a sample temperature of 500 degreesC. The thickness and composition of the amorphous interface layer an
The lower Wenlock Hangvar Formation - a sequence previously split between the Hogklint and Slite beds (Silurian, Gotland, Sweden)
Conodont faunas solve the long-standing problem regarding the relationships between the Hogklint, Tofta, and lower Slite. The name Hangvar Formation is here formally introduced for the strata identified between the Tofta Formation and the Slite Group. The Hangvar Fm. includes marls as far SW as near Paviken (previously Slite Marl), argillaceous limestones (seen only in the most distal areas access
Suicidal intent and psychiatric symptoms among inpatient suicide attempters.
The objective of this study was to investigate associations between suicidal intent and psychiatric symptoms, and to study the usefulness of the Suicidal Intent Scale (SIS) and the Comprehensive Psychopathological Rating Scale (CPRS) for suicide risk assessment in an inpatient population. One hundred and ninety-six suicide attempters, of whom 15 eventually committed suicide, were admitted to a psy
Revolutionary Cuba at 50 Growth with Equity Revisited
A balance sheet of the Cuban Revolution in terms of growth performance, equity, and the satisfaction of basic needs after 50 years is a mixed bag. Growth performance has been disappointing during most of the past 25 years, although there are today some encouraging new trends. Income distribution that was quite equal in 1985 has seen some deterioration since 1990. Agriculture has been one of the fa
Trait interactions help explain plant invasion success in the German flora
On the global existence of solutions to quasilinear parabolic equations
We prove, under quite general assumptions, the global existence of classical solutions for quasilinear parabolic equations in bounded domains with homogeneous Dirichlet boundary conditions. The same results for weakly coupled reaction-diffusion systems are also given. 2000 Mathematics Subject Classification.
Application of artificial neural networks in the diagnosis of urological dysfunctions
In this article, we evaluate the work out of some artificial neural network models as tools for support in the medical diagnosis of urological dysfunctions. We develop two types of unsupervised and one supervised neural network. This scheme is meant to help the urologists in obtaining a diagnosis for complex multi-variable diseases and to reduce painful and costly medical treatments since neurolog
