Parametric quantification of myocardial ischaemia using real-time perfusion adenosine stress echocardiography images, with SPECT as reference method.

Summary Background: Real-time perfusion (RTP) adenosine stress echocardiography (ASE) can be used to visually evaluate myocardial ischaemia. The RTP power modulation technique, provides images for off-line parametric perfusion quantification using Qontrast((R)) software. From replenishment curves, this generates parametric images of peak signal intensity (A), myocardial blood flow velocity (beta)

Team-based rehabilitation improves long-term aerobic capacity and health-related quality of life in patients with chronic inflammatory arthritis.

Purpose. To examine the effect of an interdisciplinary, out-patient rehabilitation programme for patients with chronic inflammatory arthritis on aerobic capacity and health-related quality of life (HRQOL). Method. One hundred and seventy-four patients, 115 with peripheral arthritis (PA) (91 women, mean age 53 years, disease duration 16 years) and 59 with spondylarthropathies (SpA), (27 women, mean

Sexual Health in Patients with Rheumatoid Arthritis: Experiences, Needs and Communication with Health Care Professionals.

Pain, fatigue and decreased joint mobility caused by rheumatoid arthritis (RA) often decrease sexual health in RA patients. Regular physiotherapy interventions in patients with RA are often aimed at improving those factors. The aim of the present study was to explore the experiences and views of patients concerning the impact of RA on their sexual health, the possible impact of physiotherapy inter

Absolute quantification of cerebral blood flow: correlation between dynamic susceptibility contrast MRI and model-free arterial spin labeling.

PURPOSE: To compare absolute cerebral blood flow (CBF) estimates obtained by model-free arterial spin labeling (ASL) and dynamic susceptibility contrast MRI (DSC-MRI), corrected for partial volume effects (PVEs). METHODS: CBF was measured using DSC-MRI and model-free ASL (quantitative signal targeting with alternating radiofrequency labeling of arterial regions) at 3 T in 15 subjects with brain tu

Embodied identity-A deeper understanding of body awareness.

The aims of this study were to explore and generate an understanding of the meaning of body awareness through explanations of the experience of body awareness given by professionals and patients in psychiatric rehabilitation. A total of 20 strategically selected healthy informants were interviewed individually and in groups. Thirteen previous interviews with physiotherapists and 11 previous interv

Inhibition of TIR domain signaling by TcpC: MyD88-dependent and independent effects on Escherichia coli virulence.

Toll-like receptor signaling requires functional Toll/interleukin-1 (IL-1) receptor (TIR) domains to activate innate immunity. By producing TIR homologous proteins, microbes inhibit host response induction and improve their own survival. The TIR homologous protein TcpC was recently identified as a virulence factor in uropathogenic Escherichia coli (E. coli), suppressing innate immunity by binding

Frequent deletion of the CDKN2A locus in chordoma: analysis of chromosomal imbalances using array comparative genomic hybridisation.

The initiating somatic genetic events in chordoma development have not yet been identified. Most cytogenetically investigated chordomas have displayed near-diploid or moderately hypodiploid karyotypes, with several numerical and structural rearrangements. However, no consistent structural chromosome aberration has been reported. This is the first array-based study characterising DNA copy number ch

Radiative lifetime measurements and transition probabilities of astrophysical interest in ErIII

Radiative lifetimes of seven excited states of Er iii have been measured using time-resolved laser-induced fluorescence following two-photon excitation. Relativistic Hartree-Fock calculations taking core-polarization effects into account are found to be in excellent agreement with the experimental results. A large set of new calculated transition probabilities is presented for many transitions of

Prognostic value of cell adhesion in esophageal adenocarcinomas.

Increased understanding of the molecular processes associated with the dysplasia-adenocarcinoma sequence linked to Barrett's esophagus may be beneficial for early tumor detection and refined diagnosis as well as for improved prognostication. We applied immunohistochemical staining for the markers Ki-67, p53, beta-catenin and E-cadherin in order to evaluate their prognostic importance in 59 Barrett

Comprehensive CT Evaluation in Acute Ischemic Stroke: Impact on Diagnosis and Treatment Decisions.

Background. With modern CT imaging a comprehensive overview of cerebral macro- and microcirculation can be obtained within minutes in acute ischemic stroke. This opens for patient stratification and individualized treatment. Methods. Four patients with acute ischemic stroke of different aetiologies and/or treatments were chosen for illustration of the comprehensive CT protocol and its value in sub

An open access technique to create pneumoperitoneum in laparoscopic surgery.

BACKGROUND: An open access technique might reduce severe vascular and visceral injuries. An open access technique through the umbilical cicatrix tube has been developed as a routine method with the goal to be easy, safe and used by all surgeons in patients without a previous midline incision. AIM: To evaluate the open technique in a prospective study in 100 consecutive laparoscopic operations rega

CFD Approach to Analyze Transport Phenomena Coupled Chemical Reactions Relevant for Methane Reformers

Various transport phenomena in conjunction with chemical reactions are strongly affected by reformer configurations and the properties of the involved porous catalyst layers. The considered composite duct is relevant for a methane steam reformer and consists of a porous layer for the catalytic chemical reactions, the fuel gas flow duct and the solid plate. In this paper, a fully three-dimensional

Factor H dysfunction in patients with atypical hemolytic uremic syndrome contributes to complement deposition on platelets and their activation.

Atypical hemolytic uremic syndrome (aHUS) may be associated with mutations at the C-terminal of factor H (FH). FH binds to platelets via the C-terminal as previously shown using a construct consisting of short consensus repeats (SCRs) 15-20. Four FH mutations, in SCR15 (C870R) and SCR20 (V1168E, E1198K, E1198Stop) in aHUS patients, were studied regarding their ability to allow complement activatio

Antibody formation and specificity in Bethesda-negative brother pairs with haemophilia A.

Antibodies directed towards non-neutralizing epitopes on the factor VIII protein (FVIII) may be detected in patients with haemophilia A. We evaluated the prevalence of non-neutralizing antibodies, in 201 inhibitor-negative brother pairs with severe haemophilia A, enrolled in the Malmö International Brother Study and the Haemophilia Inhibitor Genetics Study. To evaluate binding specificity of the a

Calcium binding and thermostability of carbohydrate binding module CBM4-2 of Xyn10A from Rhodothermus marinus.

Calcium binding to carbohydrate binding module CBM4-2 of xylanase 10A (Xyn10A) from Rhodothermus marinus was explored using calorimetry, NMR, fluorescence, and absorbance spectroscopy. CBM4-2 binds two calcium ions, one with moderate affinity and one with extremely high affinity. The moderate-affinity site has an association constant of (1.3 +/- 0.3) x 10(5) M(-1) and a binding enthalpy DeltaH(a)

Reproductive hormones in plasma over the menstrual cycle in primary dysmenorrhea compared with healthy subjects.

The pathogenesis of primary dysmenorrhea is still poorly understood. The objective of the present investigation was to study differences in plasma concentrations of reproductive hormones in women with primary dysmenorrhea vs. healthy controls. In a prospective, parallel-group study we determined the plasma concentrations of oxytocin, vasopressin, follicle-stimulating hormone (FSH), luteinizing hor
