An efficient method is proposed for the evaluation of the absorption and the transport scattering coefficients from a time-resolved reflectance or transmittance distribution. The procedure is based on a library of Monte Carlo simulations and is fast enough to be used in a nonlinear fitting algorithm. Tests performed against both Monte Carlo simulations and experimental measurements on tissue phant

The influence of two different concentrations of iv naloxone infusion on the analgesia and adverse effects of epidural morphine were compared in a double-blind, placebo-controlled study. Forty-five patients undergoing gallbladder surgery were provided postoperative analgesia by 4 mg epidural morphine; they then received an iv infusion over a 12-h period consisting of either 5 micrograms X kg-1 X h

Introduction Angiotensin-receptor blockers may exert favourable anti-arrhythmic effects in atrial fibrillation (AF), but their mechanisms are not fully understood. In this study, we tested the hypotheses that (i) candesartan reduces atrial fibrillatory rate and (ii) fibrillatory rate and its response to candesartan are related with the outcome of cardioversion. For this purpose, a post hoc subanal

We monitored gastrin release in response to locally applied candidate messengers in intact conscious rats. Earlier studies have been performed on anaesthetized animals, isolated pieces of antrum, or purified preparations of gastrin cells. In this study we created an experimental situation to resemble physiological conditions, using reverse microdialysis to administer regulatory peptides and amines

Adjuvant pelvic radiotherapy has the potential to eradicate micrometastases within the irradiated field but has not resulted in survival improvements in randomized studies. This illustrates the need for systemic therapy. Chemotherapy, mainly with anthracyclines, platinum compounds, and taxanes, renders high response rates although this unfortunately translates in only modest improvements in progre

Aim. The aim of this study was to investigate the role of two candidate gene polymorphisms for insulin resistance and lipid levels in obese children and adolescents. Methods. Two markers of insulin resistance and lipid levels, Pro12Ala in peroxisome proliferator-activated receptor-gamma2 (PPARG) and G276T in adiponectin (ADIPOQ), were genotyped in 285 obese children and adolescents. As the apolipo

A possible downstream effect of high in-hospital bed occupancy is that patients in the emergency department (ED) who would benefit from in-hospital care are denied admission. The present study aimed at evaluating this hypothesis through investigating associations between in-hospital bed occupancy at the time of presentation in the ED and the probability for unplanned 72-hour (72-h) revisits to the

Structural flexibility is an essential attribute, without which few proteins could carry out their biological functions. Much information about protein flexibility has come from x-ray crystallography, in the form of atomic mean-square displacements (AMSDs) or B factors. Profiles showing the AMSD variation along the polypeptide chain are usually interpreted in dynamical terms but are ultimately gov

The t(5;12) translocation, associated with chronic myelomonocytic leukemia, generates a novel gene encoding a protein, TEL-PDGF beta R, composed of the 154 amino-terminal amino acids of the transcription factor TEL and the transmembrane and intracellular part of the PDGF beta-receptor (PDGF beta R). TEL also occurs as a tumor-associated fusion partner for the tyrosine kinases c-ABL, JAK2 and TRK-C

Background: There are clinical similarities between frontotemporal dementia (FTD) and depression. The aim is to study co-aggregation of depression in families with FTD, indicating the existence of common aetiological factors. Methods: The study included 74 index patients with FTD and their 540 first-degree relatives above the age of 15 years. Occurrence of depression was studied at 3 different lev

AIMS: The aims of this study were primarily to investigate the prevalence, severity and impact on daily life of Lower Urinary Tract Symptoms (LUTS) in a clinical sample of stroke patients and secondly to identify factors associated with LUTS. MATERIALS AND METHODS: This was a cross-sectional, hospital based survey whereby stroke patients were invited by letter to complete The Danish Prostatic Symp

Increasing awareness of atrial fibrillation (AF) and its impact on public health revives interest in identification of noninvasive markers of predisposition to AF and ECG-based risk stratification. P-wave duration is generally accepted as the most reliable noninvasive marker of atrial conduction, and its prolongation has been associated with history of AF. However, patients with paroxysmal AF with

To determine the value of magnetic resonance imaging (MRI) of bones and joints in patients with recent-onset rheumatoid arthritis (RA) treated for 2 years from diagnosis with disease-modifying anti-rheumatic drugs (DMARDs) and glucocorticoids.

Summary Approximately 10% of the patients diagnosed with type 2 diabetes (T2D) have detectable serum levels of glutamic acid decarboxylase 65 autoantibodies (GADA). These patients usually progress to insulin dependency within a few years, and are classified as being latent autoimmune diabetes in adults (LADA). A decrease in the frequency of peripheral blood natural killer (NK) cells has been repor

OBJECTIVES: The purpose of this study was to determine whether statin treatment is effective and safe in very elderly (80 years and older) acute myocardial infarction (AMI) patients. BACKGROUND: Elderly individuals constitute an increasing percentage of patients admitted to hospitals for AMI. Despite that these patients have a higher mortality risk, the application of evidence-based medicine remai

Background Increased cancer risk after psoriasis has been observed in previous studies, whereas little is known about the prognosis in cancer patients with previously diagnosed psoriasis. Objectives We aimed at examining the cancer-specific and overall mortality among psoriatic cancer patients compared with the reference population. Methods The population-based Swedish registers were used to ident

Bile duct obstruction is associated with hepatic accumulation of leukocytes and liver injury. Emerging data suggest that platelets may play an important role in tissue damage and inflammation. Herein, we characterized the platelet response in cholestatic liver injury and evaluated the role of Rho-kinase signaling. For this purpose, C57BL/6 mice were treated with the Rho-kinase inhibitor Y-27632 (1

The propagation of a pulsed elastic wave in the following geometry is considered. An elastic half-space has a surface layer of a different material and the layer furthermore contains a bounded 3-D inhomogeneity. The exciting source is an explosion, modelled as an isotropic pressure point source with Gaussian behaviour in time. The time-harmonic problem is solved using the null field approach (the
