The establishment and utility of Sweha-Reg: a Swedish population-based registry to understand hereditary angioedema

ABSTRACT: BACKGROUND: The importance of acquiring comprehensive epidemiological and clinical data on hereditary angioedema has increasingly caught the attention of physicians and scientists around the world. The development of networks and creation of comprehensive policies to improve care of people suffering from rare diseases, such as hereditary angioedema, is a stated top priority of the Europe

Programmed cross flow asymmetrical flow field-flow fractionation for the size separation of pullulans and hydroxypropyl cellulose

Different functions for the programming of the cross flow in asymmetrical flow field-flow fractionation were studied with the aim to find the flow conditions most suitable for the molar mass distribution analysis of high molecular weight polysaccharides. A mixture of four differently sized pullulans covering the molar mass range 5.8 x 10(3)-1.6 x 106 g mol(-1) were used as a model sample. Two type

Urinary excretion of oligosaccharides induced by galactose given orally or intravenously

The effect of oral administration of galactose, lactose, and sucrose and intravenous injection of galactose on the urinary excretion of blood-group-active oligosaccharides has been studied. Galactose given either as the free sugar, a glycoside (lactose) or a constituent of normal diet was an absolute requirement for the formation and excretion of A-trisaccharide, B-trisaccharide and 2'-fucosylgala

Brandteknisk dimensionering med riskbaserade ekvationer

The aim of this study was to derive simple risk-based equations to be used in fire safety design. Design values for the equations are derived from a specific target risk, usually described as the target reliability index β. Using the design values with accepted calculation methods would result in an accepted engineering solution to the problem. This approach is commonly used in structural engineer

Improved methods for prepurification and detection of Staphylococcal Enterotoxin B from cell-free culture filtrate

An improved ELISA method for the detection of Staphylococcal. Enterotoxin B (SEB) in protein A preparations is presented. Fab fragments were obtained by digestion with papain of anti-SEB IgG bound to SEB immobilized on Sepharose 4B. Anti-SEB and peroxidase-labeled Fab fragments from secondary antibodies were successfully used in a modified ELISA of SEB in protein A preparations. SEB-Sepharose was

Silicon neural interfaces -Design and biomedical aspects-

This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon. A method

Impact of postprandial glycaemia on health and prevention of disease.

Postprandial glucose, together with related hyperinsulinemia and lipidaemia, has been implicated in the development of chronic metabolic diseases like obesity, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). In this review, available evidence is discussed on postprandial glucose in relation to body weight control, the development of oxidative stress, T2DM, and CVD and in maintain

Elucidation of the sex-pheromone biosynthesis producing 5,7-dodecadienes in Dendrolimus punctatus (Lepidoptera: Lasiocampidae) reveals Delta11- and Delta9-desaturases with unusual catalytic properties

Sex pheromones produced by female moths of the Lasiocampidae family include conjugated 5,7-dodecadiene components with various oxygenated terminal groups. Here we describe the molecular cloning, heterologous expression and functional characterization of desaturases associated with the biosynthesis of these unusual chemicals. By homology-based PCR screening we characterized five cDNAs from the fema

Gender equality in the work of local research ethics committees in Europe: a study of practice in five countries

Background: Funding organisations and research ethics committees (RECs) should play a part in strengthening attention to gender equality in clinical research. In the research policy of European Union (EU), funding measures have been taken to realise this, but such measures are lacking in the EU policy regarding RECs. Objective: To explore how RECs in Austria, Germany, Ireland, The Netherlands and

On the biologically effective dose (BED)-using convolution for calculating the effects of repair: I. Analytical considerations.

This work presents a new mathematical formulation of biologically effective dose (BED) for radiation therapy where effects of repair need to be considered. The formulation is based on the observation that the effects of repair, both during protracted irradiation and of incomplete repair between fractions, can be written using a convolution, i.e. [Formula: see text] where T is the total irradiation

Second primary malignancies among women with uterine sarcoma

Objective. Uterine sarcomas (US) are rare malignancies with unclear aetiology. Studies on uterine sarcomas in the setting of second primary malignant tumours can provide clues to aetiology and identify side effects of different treatments. Methods. A cohort of 8606 cases of US was extracted from the data from 13 cancer registries and followed for second primary cancers within the period 1943-2000.

Culture-independent quantification of Salmonella enterica in carcass gauze swabs by flotation prior to real-time PCR

To facilitate quantitative risk assessment in the meat production chain, there is a need for culture-independent quantification methods. The aim of this study was to evaluate the use of flotation, a non-destructive sample preparation method based on traditional buoyant density centrifugation, for culture-independent quantification of intact Salmonella in pig carcass gauze swabs (100 cm(2)) prior t

Clustering of MS spectra for improved protein identification rate and screening for protein variants and modifications by MALDI-MS/MS

It is an established fact that allelic variation and post-translational modifications create different variants of proteins, which are observed as isoelectric and size subspecies in two-dimensional gel based proteomics. Here we explore the stromal proteome of spinach and Arabidopsis chloroplast and show that clustering of mass spectra is a useful tool for investigating such variants and detecting

Complications to Cerebrospinal Fluid Drainage and Predictors of Spinal Cord Ischemia in Patients With Aortic Disease Undergoing Advanced Endovascular Therapy

Objective: To study the complications after cerebrospinal fluid (CSF) drainage and predictors of spinal cord ischemia (SCI) after advanced endovascular therapy with CSF drainage for complex aortic disease. Methods: Between 2009 and 2012, 88 attempts of CSF drainage insertions/84 operations/83 patients, of the 658 operations for aortoiliac diseases, were performed. Results: Indications for therapy

Thermal Behavior of Poly(L-lactide) Having Low L-Isomer Content of 94% after Compressed CO2 Treatment

The effect of compressed CO2 treatment on the thermal behavior of poly(L-lactide) (PLLA) with low L-isomer content of 94% was studied by using differential scanning calorimetry (DSC) and temperature modulated DSC. It was shown that the treated samples displayed rich thermal transition signals during DSC heating, which is differ from the PLLA having high L-isomer content, including enthalpy relaxat
