How to misuse echo contrast

Background: Primary intracardiac tumours are rare, there are however several entities that can mimic tumours. Contrast echocardiography has been suggested to aid the differentiation of various suspected masses. We present a case where transthoracic echocardiography completely misdiagnosed a left atrial mass, partly due to use of echo contrast. Case presentation: An 80 year-old woman was referred f

Measurement of inclusive and dijet D* meson cross sections in photoproduction at HERA

The inclusive photoproduction of D* mesons and of D*-tagged dijets is investigated with the H1 detector at the ep collider HERA. The kinematic region covers small photon virtualities Q(2) < 2 GeV2 and photon-proton centre-of-mass energies of 100< W-gamma p < 285 GeV. Inclusive D* meson differential cross sections are measured for central rapidities vertical bar eta(D*)vertical bar < 1.5 and transv

Azurophil Granule Proteins Constitute the Major Mycobactericidal Proteins in Human Neutrophils and Enhance the Killing of Mycobacteria in Macrophages

Pathogenic mycobacteria reside in, and are in turn controlled by, macrophages. However, emerging data suggest that neutrophils also play a critical role in innate immunity to tuberculosis, presumably by their different antibacterial granule proteins. In this study, we purified neutrophil azurophil and specific granules and systematically analyzed the antimycobacterial activity of some purified azu

Vitamin K-dependent protein S - studies of synthesis, structure and function

This thesis is based on four projects with the overall aim to investigate vitamin K-dependent protein S functions in relation to its structure. The anticoagulant functions of protein S can be divided in three: 1) cofactor for activated protein C (APC), 2) cofactor for tissue factor pathway inhibitor (TFPI) and 3) APC and TFPI-independent anticoagulant functions. Microparticles might be shed from

Uncertainty regarding waste handling in everyday life

According to our study, based on interviews with households in a residential area in Sweden, uncertainty is a cultural barrier to improved recycling. Four causes of uncertainty are identified. Firstly, professional categories not matching cultural categories—people easily discriminate between certain categories (e.g., materials such as plastic and paper) but not between others (e.g., packaging and

Fatty fish consumption and risk of latent autoimmune diabetes in adults.

It has been suggested that intake of fatty fish may protect against both type 1 and type 2 diabetes. Hypotheses rest on the high marine omega-3 fatty acid eicosapentaenoic acid+docosahexaenoic acid (EPA+DHA) and vitamin D contents, with possible beneficial effects on immune function and glucose metabolism. Our aim was to investigate, for the first time, fatty fish consumption in relation to the ri

Multi-Scale Characterization of Lyotropic Liquid Crystals Using 2H and Diffusion MRI with Spatial Resolution in Three Dimensions.

The ability of lyotropic liquid crystals to form intricate structures on a range of length scales can be utilized for the synthesis of structurally complex inorganic materials, as well as in devices for controlled drug delivery. Here we employ magnetic resonance imaging (MRI) for non-invasive characterization of nano-, micro-, and millimeter scale structures in liquid crystals. The structure is mi

Differential Capacitance of Room Temperature Ionic Liquids: The Role of Dispersion Forces

We investigate theoretical models of room temperature ionic liquids, and find that the experimentally observed camel-shape of the differential capacitance is strongly related to dispersion interactions in these systems. At low surface charge densities, the loss of dispersion interactions in the vicinity of the electrodes generates depleted densities, with a concomitant drop of the differential cap

Lighting control systems in individual offices at high latitude: measurements of electricity savings and users preferences

Abstract in UndeterminedAn efficient lighting control systems (LCS) should take advantage of the natural light available, but this presents some technical challenges as well as user related issues. So far, the assessment of lighting energy consumption of LCS has been based on technical features rather than the occupants’ acceptance.This article presents the results of a monitoring study providing

Individual resiliency factors from a genetic perspective: results from a twin study.

This article is part of the Twin Mother's Study, a study that examines influences on maternal adjustment. A number of studies have investigated the importance of genetic factors for mental health, but few of these examine how genes and the environment influence resiliency/salutogenic factors. This article investigates the relative importance of genetic and environmental influences on resiliency/sa

Sämre läkarkontinuitet efter vårdvalet för patienter med diabetes - En jämförelse före och efter införande av hälsoval Skåne i Malmö.

Continuity of care is one of the core values of family medicine and both patients and doctors consider it a vital aspect of the care of patients with chronic diseases. In 2009 a national health care reform was implemented in primary care in Sweden. This study compared the longitudinal continuity of care in primary care before and after this reform in 7121 adult diabetes patients living in Malmö. O

Local and translational dynamics in DNA-lipid assemblies monitored by solid-state and diffusion NMR.

The influence of electrostatic interactions on the dynamic properties of complexes containing DNA and mixtures of cationic- (DDA) and zwitterionic (DLPC) lipids are studied by means of NMR. The systems are arranged in lamellar membrane stacks intercalated by DNA molecules. This is confirmed by 31P-NMR, where a superposition of an axially symmetric powder pattern arising from the phospholipid membr

International myeloma working group (IMWG) consensus statement and guidelines regarding the current status of stem cell collection and high-dose therapy for multiple myeloma and the role of plerixafor (AMD 3100)

Multiple myeloma is the most common indication for high-dose chemotherapy with autologous stem cell support (ASCT) in North America today. Stem cell procurement for ASCT has most commonly been performed with stem cell mobilization using colony-stimulating factors with or without prior chemotherapy. The target CD34+ cell dose to be collected as well as the number of apheresis performed varies throu

Mesozoic marine tetrapod diversity: mass extinctions and temporal heterogeneity in geological megabiases affecting vertebrates

The fossil record is our only direct means for evaluating shifts in biodiversity through Earth's history. However, analyses of fossil marine invertebrates have demonstrated that geological megabiases profoundly influence fossil preservation and discovery, obscuring true diversity signals. Comparable studies of vertebrate palaeodiversity patterns remain in their infancy. A new species-level dataset

Why we should ever bother about wh-questions: On NPI-licensing properties of wh-questions in Swedish

This paper is an attempt to solve the somewhat elusive polarity item licensing properties of wh-questions in Swedish. As has been observed by Klima (1964) for English, NPIs are gener¬ally not compatible with genuinely information seeking wh-questions, but tend to induce rhe¬torical interpretations. Distin-guishing between three types of wh-questions and the kind of information they request, I will

Diabetic Vascular Complications & Inflammation - role of NFAT and TNFalpha

Vascular complications of diabetes account for the majority of morbidity and mortality among diabetic patients. Large clinical trials have identified hyperglycemia as a risk factor in the development of diabetic vascular complications. The effects of hyperglycemia on the vessel wall are not fully understood, but chronic vascular inflammation has been implicated to play a major role in the pathogen

Interleukin-6 concentrations in the urine and dipstick analyses were related to bacteriuria but not symptoms in the elderly: a cross sectional study of 421 nursing home residents

Background: Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) in

Dating Components of Human Atherosclerotic Plaques

Rationale: Atherosclerotic plaques that give rise to acute clinical symptoms are typically characterized by degradation of the connective tissue and plaque rupture. Experimental studies have shown that mechanisms to repair vulnerable lesions exist, but the rate of remodeling of human plaque tissue has not been studied. Objective: In the present study, we determined the biological age of different

A physico-chemical characterisation of new raw materials for microcrystalline cellulose manufacturing

A detailed physico-chemical characterisation of potential new cellulose sources (rice husk, hemp stalk, and coniferous needles), and microcrystalline cellulose (MCC) manufactured from them, was made in this work. The length and the width of the cellulose crystallites were determined by wide-angle X-ray scattering (WAXS), crystallinities were studied by means of WAXS and solid state cross polarisat
