Long term (13 years) prognosis after primary intracerebral haemorrhage: a prospective population based study of long term mortality, prognostic factors and causes of death.

INTRODUCTION: Many studies have focused on short term mortality after primary intracerebral haemorrhage (ICH) whereas long term prognosis and causes of death have been less studied. We therefore examined these issues in a population based cohort of 1 year ICH survivors. METHODS: ICH patients in a defined Swedish population (1.14 million inhabitants) were prospectively registered during 1996. Patie

Size- and shape-dependent phase diagram of In-Sb nano-alloys

Nano-scale alloy systems with at least one dimension below 100 nm have different phase stabilities than those observed in the macro-scale systems due to a large surface to volume ratio. We have used the semi-empirical thermodynamic modelling, i.e. the CALPHAD method, to predict the phase equilibria of the In-Sb nano-scale systems as a function of size and shape. To calculate the size- and shape-de

Photoemission electron microscopy of localized surface plasmons in silver nanostructures at telecommunication wavelengths

We image the field enhancement at Ag nanostructures using femtosecond laser pulses with a center wavelength of 1.55 mu m. Imaging is based on non-linear photoemission observed in a photoemission electron microscope (PEEM). The images are directly compared to ultra violet PEEM and scanning electron microscopy (SEM) imaging of the same structures. Further, we have carried out atomic scale scanning t

Epitaxial growth and surface studies of the Half Heusler compound NiTiSn (001)

The Half Heuslers are currently an attractive family of compounds for high temperature thermoelectrics research, and recently, there has been renewed interest since some of these compounds are proposed to be topological insulators. NiTiSn belongs to the family of 18 valence electron Half Heuslers that are predicted to be semiconducting, despite being composed entirely of metallic elements. The gro

Familial risks of breast and prostate cancers: Does the definition of the at risk period matter?

Aim: 'Being at familial risk' may have different connotations in studies on familial risk of cancer. The register-based definition of a family history considers individuals with an affected relative at familial risk independently of the family member's diagnostic time. Alternatively, the individuals are classified to be at familial risk only after the diagnosis date of their relative, relevant to

Complaints, Complainants, and Rulings Regarding Drug Promotion in the United Kingdom and Sweden 2004–2012: A Quantitative and Qualitative Study of Pharmaceutical Industry Self-Regulation

Background In many European countries, medicines promotion is governed by voluntary codes of practice administered by the pharmaceutical industry under its own system of self-regulation. Involvement of industry organizations in policing promotion has been proposed to deter illicit conduct, but few detailed studies on self-regulation have been carried out to date. The objective of this study was to

Hole Trapping: The Critical Factor for Quantum Dot Sensitized Solar Cell Performance

The performance of the current quantum dot (QD) solar cells is limited by several deficiencies. One of them is the existence of surface traps, especially hole traps, which are blocking the hole injection into the electrolyte. The trapping can be efficiently suppressed by growing a shell of wider band gap material around the core dot. Optimum parameters of such a shell layer for photovoltaic applic

Dermal uptake study with 4,4'-diphenylmethane diisocyanate led to active sensitization

BACKGROUND:To investigate the dermal uptake of 4,4'-diphenylmethane diisocyanate (4,4'-MDI), a study was performed in which 2 female volunteers were exposed to 10 and 25 mg, respectively, of 4,4'-MDI by applying 2.0% 4,4'-MDI in petrolatum over areas where the surface concentration corresponded to 800 µg/cm(2) . Ten days later, they developed eczematous dermatitis at the area of application.OBJECT

Modification of the Size of Supported Clusters by Coadsorption of an Organic Compound: Gold and l-Cysteine on Rutile TiO(2)(110).

Using X-ray photoelectron spectroscopy we studied the coadsorption of the amino acid l-cysteine and gold on a rutile TiO(2)(110) surface under ultrahigh vacuum conditions. Irrespective of the deposition order, i.e., irrespective of whether l-cysteine or gold is deposited first, the primary interaction between l-cysteine and the gold clusters formed at the surface takes place through the deprotonat

Is the physician's adherence to prescription guidelines associated with the patient's socioeconomic position? - An analysis of statin prescription in South Sweden.

BACKGROUND: Knowledge about the social and economical determinants of prescription is relevant in health care systems like the Swedish one, which is based on the principle of equity, and which aims to allocate resources on the basis of need and not on criteria that are based on social constructs. We therefore investigated the association between patient and health care practice (HCP) characteristi

Moving to Serene Nature May Prevent Poor Mental Health-Results from a Swedish Longitudinal Cohort Study.

Green spaces are recognized for improving mental health, but what particular kind of nature is required is yet not elucidated. This study explores the effect of specific types of recreational nature qualities on mental health. Longitudinal data (1999/2000 and 2005) from a public health survey was distributed to a stratified sample (n = 24,945) of a Swedish population. People from rural or suburban

Misreporting and misclassification: implications for socioeconomic disparities in body-mass index and obesity.

Body-mass index (BMI) has become the standard proxy for obesity in social science research. This study deals with the potential problems related to, first, relying on self-reported weight and height to calculate BMI (misreporting), and, second, the concern that BMI is a deficient measure of body fat (misclassification). Using a regional Swedish sample, we analyze whether socioeconomic disparities

Defining the hematopoietic stem cell niche: the chicken and the egg conundrum

Understanding the in vivo regulation of hematopoietic stem cells (HSCs) will be critical to identifying key factors involved in the regulation of HSC self-renewal and differentiation. The niche (microenvironment) in which HSCs reside has recently regained attention accompanied by a dramatic increase in the understanding of the cellular constituents of the bone marrow HSC niche. The use of sophisti

Clinical aspects of using exhaled NO in asthma diagnosis and management

Background Current guidelines recommend tailoring of asthma management according to disease control, which is largely defined by increased symptoms and deterioration in lung function. These features do not reflect the severity nor the type of the asthmatic airway inflammation. Fractional exhaled nitric oxide (FENO) is a simple, non-invasive and cost-effective online test applicable in both adults

A Six-Year Exercise Program Improves Skeletal Traits without Affecting Fracture Risk - a Prospective Controlled Study in 2621 Children.

Most pediatric exercise intervention studies, that evaluates the effect on skeletal traits include volunteers and follow bone mass for less than three years. We present a population-based six-year controlled exercise intervention study in children with also bone structure and incident fractures as endpoints. Fractures were registered in 417 girls and 500 boys in the intervention group (3969 person

Thermopower as a tool to investigate many-body effects in quantum systems

Measuring the thermopower of a confined quantum system reveals important information about its excitation spectrum. Our simulations show how this kind of transport spectroscopy is able to extract a clear signal for the onset of Wigner localization in a nanowire segment. This demonstrates that thermopower measurements provide a tool for investigating complex many-body quantum effects, which is less

C-Reactive Protein, Fibrinogen, and Cardiovascular Disease Prediction

Background There is debate about the value of assessing levels of C-reactive protein (CRP) and other biomarkers of inflammation for the prediction of first cardiovascular events. Methods We analyzed data from 52 prospective studies that included 246,669 participants without a history of cardiovascular disease to investigate the value of adding CRP or fibrinogen levels to conventional risk factors
