The first excited 2(+) state of the unstable isotope Sn-110 has been studied in safe Coulomb excitation at 2.82 MeV/u using the MINIBALL array at the REX-ISOLDE post accelerator at CERN. This is the first measurement of the reduced transition probability of this state using this method for a neutron deficient Sn isotope. The strength of the approach lies in the excellent peak-to-background ratio t

Background: Collagenous colitis is a chronic inflammatory bowel disease accompanied mainly by nonbloody diarrhea. The objectives of treatment are to alleviate the symptoms and minimize the deleterious effects on health-related quality of life (HRQOL). There is still no generally accepted clinical definition of remission or relapse. The purpose of this study was to analyze the impact of bowel sympt

Chemokine signaling has been implicated in directing colonization of the fetal thymus by hematopoietic precursors. However, the patterns of expression of the chemokine receptors responsible for directing thymic colonization by the earliest thymic migrants remain unknown. We have identified heterogeneity within the earliest thymus seeding cells based on chemokine receptor expression. By analyzing t

The aggregation behavior of an amphiphilic supramolecular system, with potential application as a tumor-specific magnetic resonance imaging contrast agent, has been studied in detail by dynamic light scattering, small-angle neutron scattering and cryotransmission electron microscopy. The system was constituted of mixed aggregates formed by an anionic unimer containing the DTPAGlu, a chelating agen

Conflicting results have been reported of the long-term effects of treatment with inhaled corticosteroids (ICS) on bone. The objective of this study was to compare ICS users and non-users regarding bone mineral density (BMD) in a large population. A total of 65 225 adults participated in a cross-sectional study in the Nord-Trondelag Health Study 1995-1997. Those reporting asthma or asthma-related

The scope of this work is a new methodology to correct conventional near-infrared (NIR) data for scattering effects. The technique aims at measuring the absorption coefficient of the samples rather than the total attenuation measured in conventional NIR spectroscopy. The main advantage of this is that the absorption coefficient is independent of the path length of the light inside the sample and t

It is possible that the low levels of production of exopolysaccharides (EPSs) by lactic acid bacteria could be improved by altering the levels of enzymes in the central metabolism that influence the production of precursor nucleotide sugars. To test this hypothesis, we identified and cloned the galU gene, which codes for UDP glucose pyrophosphorylase (GalU) in Streptococcus thermophilus LY03. Homo

OBJECTIVES: To standardise the colorimetric assay based on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) for the rapid detection of rifampicin-resistant Mycobacterium tuberculosis in clinical practice and to evaluate the assay on a collection of 92 clinical isolates. DESIGN: The Bactec method was used as the reference method. Rifampicin was used for the susceptibility testing

Unexpected outcomes in breast cancer demand a refinement of prognostic criteria. This study therefore investigated the prognostic relevance of cyclin expression in a cohort of 332 T1-T2 NO infiltrating ductal carcinomas with long-term follow-up (median 99 months). By univariate analysis, tumour size, histopathological grade, hormone receptor content, cyclin E, cyclin B, and the Ki-S5 (Ki-67) index

Long-term training of breath-hold diving reduces the hypercapnic ventilatory response (HCVR), an index of the CO(2) sensitivity. The aim of the present study was to elucidate whether also short-term apnea training (repeating apneas with short intervals) reduces the HCVR, thereby being one contributing factor explaining the progressively increasing breath-holding time (BHT) with repetition of apnea

High-order harmonic generation in gases by use of femtosecond lasers is a source of ultrashort pulses in the extreme-ultraviolet (XUV). For many applications it is necessary to select radiation of only one specific harmonic order without affecting the duration of the ultrashort pulse. A three-grating monochromator that meets this demand has been designed and modeled by ray tracing as well as by wa

The pressure dependencies of the crystal structures of the polymeric metallocenes lithium cyclopentadienide (LiCp) and potassium cyclopentadienide (KCp) have been determined by synchrotron X-ray powder diffraction. The decrease of the volume of LiCp by 34% up to a pressure of p = 12.2 GPa and of KCp by 23% at p = 5.3 GPa as well as the bulk moduli of K = 7.7 GPa for LiCp and 4.9 GPa for KCp indica

In this paper a new perspective on modeling of transient phenomena in the context of sinusoidal audio modeling and coding is presented. In our approach the task of finding time-varying amplitudes for sinusoidal models is viewed as an AM demodulation problem. A general perfect reconstruction framework for amplitude modulated sinusoids is introduced and model reductions lead to a model for audio com

We demonstrate a new scheme for extreme ultraviolet (xuv) Fourier-transform spectroscopy based on the generation of two phase-locked high-harmonic beams. It allows us to measure for the first time interferograms at wavelengths as short as 90 nm, and open the perspective of performing high-resolution Fourier-transform absorption spectroscopy in the xuv. Our measurements also demonstrate that a prec

The mufti-layer dynamic soil chemistry SAFE model was used to study the dynamics of recovery in the F1 catchment at Lake Gardsjon, Sweden. The influence of (F) sulphate adsorption, and (2) changes in marine deposition, oil model predictions of recovery was studied. Sulphate adsorption/desorption in SAFE is modeled by all isotherm in which sulphate adsorption is dependent oil both the sulphate conc

Herpes simplex virus (HSV) induces a receptor on infected cells that is able to bind the Fc part of immunoglobulin G (IgG). We have examined some basic physicochemical and binding properties of the Fc receptor induced on HSV-1 infected green monkey kidney (GMK) cells in its interaction with rabbit IgG. Fixation of HSV-1 infected cells with glutaraldehyde, formaldehyde, acetone or ethanol did not i

Atmospheric mercury species/fractions were measured near a chlor-alkali plant in Sweden during August 28 to September 4, 2001. The concentration of total gaseous mercury in the plume from the plant was measured using TEKRAN and GARDIS instruments. Gaseous elemental mercury was measured using a light detection and ranging (LIDAR) technique. From vertical LIDAR sweeps through the plume from the chlo

This study was conducted to compare the reactogenicity, immunogenicity and safety of a combined two-dose (0, 6 months) hepatitis A and B vaccine (720ELU HAV, 20 mcg HBsAg) with the established three-dose (0, 1 and 6 months) hepatitis A and B vaccine (360ELU HAV, 10 mcg HBsAg). A total of 511 children aged 1-11 years who had not previously received a hepatitis A or B vaccine were enrolled in the st

Heat transfer enhancement technology provides many advantages in heat exchanger applications. It becomes even more significant in the retrofit design of shell-and-tube heat exchangers, where additional heat transfer area is often required. Tube inserts are frequently used in such applications to avoid additional exchangers, which can lead to significant cost saving. This paper discusses the select
