STUDY OBJECTIVE: Although national variation in short-term prognosis (that is, 30 day mortality) after a patients first hospitalisation for heart failure may depend on individual differences between patients, dissimilarities in hospital practices may also influence prognosis. This study, therefore, sought to disentangle patient determinants from institutional factors that might explain such variat
The recent article by de Souza, Lorenzini and Rizzatti J. A. V. de Souza, F. Lorenzini, and M. R. Rizatti, J. Appl. Phys. 104, 034701 2008 in this journal needs corrections and clarifications on several points. The model used by them is not suitable for the study of erythema. © 2009 American Institute of Physics.

We present a versatile and compact fiber optic probe for real-time determination of the absorption and the reduced scattering coefficients from spatially resolved continuous wave diffuse reflectance measurements. The probe collects the diffuse reflectance at six distances in the range 0.6 - 7.8 mm at four arbitrary wavelengths, which were 660, 785, 805, and 974 nm in these experiments. The maximum
The plasma membrane H+-ATPase is activated by binding of 14-3-3 protein to the phosphorylated C terminus. Considering the large number of 14-3-3 and H+-ATPase isoforms in Arabidopsis (13 and 11 expressed genes, respectively), specificity in binding may exist between 14-3-3 and H+-ATPase isoforms. We now show that the H'-ATPase is the main target for 14-3-3 binding at the plasma membrane, and that
The effectiveness of extracting p,p'-DDT and p,p'-DDE from aged contaminated soil samples by means of pressurized liquid extraction (PLE) was evaluated. Two soil samples, which were contaminated more than 10 years ago, were used in the investigation. The static extraction time was optimised and then validated against the total sum of target analytes obtained from multiple sequential extractions. T
The reported prevalence of malnutrition in pediatric hospitals ranges from 15% to 30% of patients, with an impact on growth, morbidity and mortality. Major deficits in nutrition care have been highlighted in European hospitals, and the implementation of nutrition support teams (NSTs) has been suggested as a means to improve malnutrition diagnosis and nutrition care for hospitalized patients. This
We compare different procedures for combining fixed-order tree-level matrix-element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW and MLM schemes using different matrix-element generators and different parton cascades. We find that although similar results are obtained in all cases, there are i
BACKGROUND. The objective of this study was to identify prognostic factors for predicting survival in patients with advanced renal cell carcinoma (RCC) who had undergone an allogeneic stem cell transplantation after failure on immunotherapy. METHODS. The authors Studied 70 patients with advanced RCC Who underwent allogeneic transplantation with a fludarabine-based, reduced-intensity regimen. Ten p
Heterocyclic amines (HCAs) are potent mutagens/carcinogens to which humans are frequently exposed through the consumption of cooked meat and fish food. The effect of normal intake of HCAs and their role in the aetiology of human cancer is unknown. To some extent, limitations of the existing analytical methods in monitoring the low levels of HCAs in biological samples have hindered obtaining conclu
The aim of this study was to develop, adjust and test two different methods for the estimation of drainage area and potential wetness in ridged fields. The methods were applied to a gridded digital elevation model (DEM) of a potato field in central Sweden. Elevation data were registered by a global positioning system (GPS) receiver. A high-precision real time kinematic (RTK) system was used to rec
OBJECTIVES: Airborne exposure to polycyclic aromatic hydrocarbons (PAH) in the potroom of an aluminum reduction plant was studied in relation to genotoxic or mutagenic effects, and the possibility of host genotypes of different metabolizing enzymes modifying associations between PAH exposure and genotoxic or mutagenic response was assessed. SUBJECTS AND METHODS: Ninety-eight male potroom workers a
Over the years we have seen an increased interest in businesses and in research for how to create conditions for entrepreneurship in established businesses (referring to corporate entrepreneurship). From research we know that access to and use of resources is critical for realizing corporate entrepreneurship activities. Even though the role of resources has been examined this conceptual paper iden
Despite increasing access to antiretroviral treatment (ART) in low-income countries, HIV-related mortality is high, especially in the first months following ART initiation. We aimed to evaluate the impact of TB coinfection on early mortality and to assess gender-specific predictors of mortality in a cohort of Ethiopian adults subjected to intensified casefinding for active TB before starting ART.
A ferrous gel, based on ferrous (Fe) sulphate and agarose, was used with a clinical magnetic resonance imaging (MRI) scanner to obtain relative dose distribution data from therapeutic photon and electron beams. The FeMRI gel was scanned using a new MRI acquisition protocol optimized for T1 measurements. Thorough comparisons with silicon semiconductor detector and ionization chamber measurements, a
The MAX IV facility includes two storage rings operated at 1.5 GeV and 3 GeV. Both rings make use of a 100 MHz RF system and are designed to operate with a uniform multibunch fill pattern aswell as employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. Recently, a discussion on timing modes at the MAX IV storage rings has been initiated by the user community. This i
This study analyzed direct and indirect relationships in water consumption by Macedonian economic sectors using virtual water in an input–output framework. Macedonia was found to be characterized by intensive water consumption, with some sectors having a significant virtual water content in their products. Virtual water multipliers were used to analyze the trade balance and determine whethernation
The close relationship between young children’s living conditions and their healthlater in life is well documented and a safe and healthy environment during earlychildhood promotes cognitive functions and social development during the wholelifespan. Becoming a parent is a major life transition and it is sometimes described as a stressful and vulnerable time involving changes to lifestyle and routi
