With the arrival of X-ray Free Electron Lasers (XFELs), 2D area detectors with a large dynamic range for detection of hard X-rays with fast readout rates are required for many types of experiments. Extracting the desired information from these detectors has been challenging due to unpredicted fluctuations in the measured images. For techniques such as time-resolved X-ray Diffuse Scattering (XDS),

OBJECTIVE: Recordings of blood flow velocity waveform in the ductus venosus (DV) and the umbilical vein (UV) are routinely used in order to predict the fetal condition in high-risk pregnancies. This study investigates the relationship between pathological blood flow in the two vessels and perinatal outcome. METHODS: High-risk pregnancies (n=11865) admitted during 1993-2011 for blood flow examinati

To create normative data in children from binocular multifocal ERG (mfERG) recordings and compare results with the macular thickness.

The stratum corneum (SC) is an effective permeability barrier. One strategy to increase drug delivery across skin is to increase the hydration. A detailed description of how hydration affects skin permeability requires characterization of both macroscopic and molecular properties and how they respond to hydration. We explore this issue by performing impedance experiments on excised skin membranes

The composition of the gut microbiota can vary widely between individual mice of the same batch and thereby affect the resulting outcome in experimental studies. Therefore, an efficient method is needed to equalize the gut microbiota prior to the start of critical experiments. In order to minimize variations in gut microbiota between animals and provide the animals with a Gram-negative flora expos

Objectives: To characterize intraocular pressure (IOP) changes during 6 years of follow-up among patients with early, newly diagnosed glaucoma randomized to no initial treatment in the Early Manifest Glaucoma Trial (control group) and to evaluate factors associated with IOP changes in this group. Methods: Early Manifest Glaucoma Trial control patients, aged 50 to 80 years at baseline, were followe

Abstract Objective. Population-based data on the impact of bacterial infections on the course of compensated and decompensated cirrhosis as well as the occurrence, predictors of infection-related acute-on-chronic liver failure (ACLF) and its fatal outcome are limited. Material and methods. All patients with incident cirrhosis in the period 2001-2010, residing in an area of 600,000 inhabitants, wer

Orthostatic hypotension has been linked with increased mortality and cardiovascular morbidity; however, the underlying mechanisms are still unknown. The aim of the study was to assess markers of coagulability in patients with and without orthostatic hypotension who suffered transient loss of consciousness.

Cardiovascular dysfunction is common after out-of-hospital cardiac arrest as part of the postcardiac arrest syndrome, and hypothermia may pose additional impact on hemodynamics. The aim was to investigate systemic vascular resistance index (SVRI), cardiac index, and myocardial performance at a targeted temperature management of 33°C (TTM33) versus 36°C (TTM36).

Objectives To evaluate in a prospective, randomized clinical trial (RCT), symptom response among obese knee osteoarthritis (OA) patients following a feasible. intensive weight-loss program for 16 weeks Methods Eligible patients were obese [body mass index (BMI)> 30 kg/m(2)], >50 years old, with primary knee OA Participants were randomized to either a very-low-energy diet (VLED) or a low-energy die

ObjectiveWe undertook a 2-part, phase I, double-blind, placebo-controlled study to evaluate the safety and pharmacokinetics of multiple intravenous infusions of sirukumab, a human anti-interleukin-6 monoclonal antibody, in patients with cutaneous lupus erythematosus (CLE) or systemic lupus erythematosus (SLE). MethodsIn part A, patients with histologically confirmed CLE were randomized to 4 infusi

The identity of the cells that contribute to brain tumor structure and progression remains unclear. Mesenchymal stem cells (MSCs) have recently been isolated from normal mouse brain. Here, we report the infiltration of MSC-like cells into the GL261 murine glioma model. These Brain Tumor derived Mesenchymal Stem Cells (BT-MSCs) are defined with the phenotype (Lin-Sca-1+CD9+CD44+CD166+/-) and have m

A dynamic model was developed for long-term simulation of a heavy duty gas turbine. The model includes the essential control algorithm of the gas turbine as well as the most common outputs and other important intermediate variables. Control algorithm details, such as wind up protection and load limiter algorithm which have large effect on gas turbine transient behavior, are included. The model par

More and more user groups are using medical devices. Heart starters are, for example, available in public places and used by non-professionals. Different mobile medical applications, designed to help people manage their own health, are now being added to the medical device spectra. Users handling medical devices make errors, but by involving users in the risk management process, it is possible to

This is achieved through the use of efficient mixers with improved out-of-band suppression, including rejection of the second harmonic, and an local-oscillator generator achievin

Lack or dysfunction of insulin producing β cells results in the development of type 1 and type 2 diabetes mellitus, respectively. Insulin secretion is controlled by metabolic stimuli (glucose, fatty acids), but also by monoamine neurotransmitters, like dopamine, serotonin, and norepinephrine. Intracellular monoamine levels are controlled by monoamine oxidases (Mao) A and B. Here we show that MaoA

Being able to move around in the community including using different modes of transport is a prerequisite for being able to participate in activities outside home. This can be particular challenging for people with cognitive impairments. Still, research regarding public transport for people with cognitive impairments is scarce. In this narrative review scientific literature focusing on people with

In order to push the development of nanowire-based solar cells further using optimized nanowire diameter and pitch, a doping evaluation of the nanowire geometry is necessary. We report on a doping evaluation of n-type InP nanowires with diameters optimized for light absorption, grown by the use of metal-organic vapor phase epitaxy in particle-assisted growth mode using tetraethyltin (TESn) as the

The sigma-1 receptor (Sig-1R) is a single 25 kD polypeptide and a chaperone protein immersed in lipid rafts of the endoplasmic reticulum (ER) where it interacts with mitochondria at the mitochondria-associated ER membrane domain (MAM). Upon activation, the Sig-1R binds to the inositol trisphosphate receptor (IP3R), and modulates cellular calcium (Ca(2+)) homeostasis. Also, the activated Sig-1R mod
