BACKGROUND: New developments in processing of digital radiographs (DR), including multi-frequency processing (MFP), allow optimization of image quality and radiation dose. This is particularly promising in children as they are believed to be more sensitive to ionizing radiation than adults. OBJECTIVE: To examine whether the use of MFP software reduces the radiation dose without compromising qualit

An international consensus report on postresuscitation care after cardiac arrest has recently been published. Its content and main messages are in line with the recommendations from The Swedish Resuscitation Council, which include: diagnosing and treating the underlying disease, offering good general intensive care, considering hypothermia treatment, standardising prognostication and follow-up.

We consider the COST259 directional channel model (DCM) in relation to other existing channel models. The COST259 DCM is a general model for the mobile radio channel that includes narrowband power (field strength), power delay profiles, and directions of arrival. For comparison purposes, it is desirable that the channel models forming the basis of earlier simulations are contained as special cases

We have developed an algorithm for arterial luminal diameter measurement by means of ultrasound and evaluated the algorithm on agar vessel phantoms and in vivo. The algorithm utilises relative threshold detection on the inner slopes of the arterial walls before the resolution is improved by solving the equation of a straight line between the samples around the threshold value. Further, correction

BACKGROUND: The contrast medium (CM) dose-to-eGFR (estimated glomerular filtration rate) ratio has recently been advocated to express systemic exposure to CM in assessing the risk of contrast medium-induced nephropathy (CIN). PURPOSE: To evaluate how CIN risk might vary with decreasing eGFR at fixed CM-dose/eGFR ratios and other CIN risk factors, and to find a relatively safe CM-dose/eGFR ratio. M

BACKGROUND: As recently pinpointed by a genome-wide association study the serine/threonine kinase 39 (STK39) is a candidate gene for hypertension. This kinase is strongly implicated in sodium reabsorption by the kidney through its modulating effect on furosemide-sensitive and thiazide-sensitive channels. The aim of our study was to test the effects of the STK39 rs35929607A>G polymorphism on blood

Radiative lifetimes and stimulated emission have been studied in two-photon-excited carbon atoms. A strong fluorescence enhancement was detected in the direction of the exciting laser beam. Rate equations for the energy levels involved have been calculated in order to obtain number densities from the emitted light. Lifetimes were measured for the 2p3p 3p and 3D states and for the A 3[Pi]g state of

OBJECTIVE: To investigate the association between political trust in the Riksdag and lack of belief in the possibility to influence one's own health (external locus of control), taking horizontal trust into account. Design/setting/participants/measurements: The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample of 28,19

Given a weighted directed graph where some arcs can fail while others are reliable, we aim to compute a shortest pair of failure-disjoint paths. If a reliable arc is used by both paths, its cost is counted only once. We present a polynomial time algorithm to solve the problem.
