DNA methylation polymorphisms precede any histological sign of atherosclerosis in mice lacking apolipoprotein E

The present work investigates the occurrence and significance of aberrant DNA methylation patterns during early stages of atherosclerosis. To this end, we asked whether the genetically atherosclerosis-prone APOEnull mice show any changes in DNA methylation patterns before the appearance of histologically detectable vascular lesion. We exploited a combination of various techniques: DNA fingerprinti

Experiences of stigma among people with severe mental illness. Reliability, acceptability and construct validity of the Swedish versions of two stigma scales measuring devaluation/discrimination and rejection experiences

Stigma has been identified as one of the most important obstacles for a successful integration of people with mental illness into the society. Research about stigma has shown negative attitudes among the public towards people with mental illness. Studies so far have, however, put little emphasis on how these negative attitudes are perceived by the mentally ill persons. The aim of the present study

OMERACT/OARSI initiative to define states of severity and indication for joint replacement in hip and knee osteoarthritis

Objective. Time to theoretical indication of joint replacement surgery has been proposed as a primary outcome for potential structure-modifying interventions for osteoarthritis (OA). The objectives of this OMERACT/OARSI Working Group were to identify pain, physical function, and structure states that represent the progression from early to late disease for individuals with OA of the hip and knee,

The Malmo International Brother Study (MIBS): further support for genetic predisposition to inhibitor development in hemophilia patients

The issue of factors predisposing for inhibitor development in haemophilia patients is still largely unresolved. In an attempt to address this problem, we initiated a registry in 1996 of siblings with haemophilia and with or without a history of inhibitors. Four hundred and sixty families have accrued, of whom 388 suffer from haemophilia A and 72 haemophilia B. Twenty-five of the brother pairs are

Systemic interleukin-6 response to colorectal surgery originates from the bowel.

Background: Surgical trauma evokes a systemic cytokine response which is enhanced in patients with colorectal cancer. The aim of this study was to locate the origin of the systemic cytokine response to colorectal surgery. Methods: The concentrations of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) were analysed in systemic and mesenteric venous blood in 12 patients operated on

Revealing the mechanisms of sexual isolation in a case of sympatric and parallel ecological divergence

Two ecotypes of a marine intertidal snail (Littorina saxatilis), living at different microhabitats and shore levels, have evolved in sympatry and in parallel across the Galician rocky shore. These ecotypes differ in many traits (including size) due to differential adaptation. They meet, mate assortatively, and partially hybridize at the mid shore where the two microhabitats overlap. The partial se

Insulin and free oestradiol are independent risk factors for benign prostatic hyperplasia

The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied were 184 representative men, aged 72-76 y

Calculating the soot particle size distribution function in turbulent diffusion flames using a sectional method

Soot formation in a turbulent jet diffusion flame is modeled using an unsteady flamelet approach in post-process. In the present work, we apply a detailed kinetic soot model with a sectional method, and study the evolution of the particle size distribution. Detailed information on the evolution of the soot particle size distribution function is acquired. It is found that the particle size distribu

Propofol sedation and gastric emptying in volunteers

BACKGROUND: The purpose of this study was to evaluate the effects of light propofol sedation on gastric emptying and orocecal transit time (OCT). METHODS: Ten healthy male volunteers were studied on 2 occasions separated by at least 1 week and were randomly allocated to receive either propofol sedation or i.v. saline as a control. During propofol sedation the volunteers were sedated to grade 2-3 o

Cryptochromes and activity markers co-localize in bird retina during magnetic orientation

Migratory birds can use a magnetic compass for orientation during their migratory journeys covering thousands of kilometers. But how do they sense the reference direction provided by the Earth's magnetic field? Behavioral evidence and theoretical considerations have suggested that radical-pair processes in differently oriented, light-sensitive molecules of the retina could enable migratory birds t

Normal ultrasonic fetal growth ratios evaluated in cases of fetal disproportion

During a 2-year period, 5476 normal routine obstetrical ultrasound investigations were performed in the 2nd trimester (16th to 20th week). Data on biparietal diameter (BPD), abdominal diameter (AD) and femur length (FL) have been obtained from this material. Ratios between BPD/AD and BPD/FL have been calculated, and from these ratios, graphs were constructed. Only nine normal fetuses (0.2%) were f

Using burden of disease/cost-effectiveness as an instrument for district health planning: experiences from Uganda.

The burden of disease/cost-effectiveness analysis (BoD/CE) was introduced as a method for detailed planning and budgeting in 13 districts of Uganda. This endeavor can be seen as a “natural experiment”, attempting to pursue policy implementation by means of a heavy focus on rationalistic/technical arguments as a main supportive factor. However, modern theory of policy implementation, e.g. the new i

Radiation-induced increase in hyaluronan and fibronectin in bronchoalveolar lavage fluid from breast cancer patients is suppressed by smoking

Bronchoalveolar lavage (BAL) fluid was analysed from 21 patients with breast cancer, stage T1N0M0, who had undergone tumour resection and post-operative local irradiation (accumulated dose 56 Gy). The lavage was performed two months after radiotherapy, in the anterior part of the lingula (left side) or of the right middle lobe (right side), depending on which side had been exposed to radiation. Th

Effect of particle size on biogas yield from sisal fibre waste

The degradation and biogas production potential of sisal fibre waste could be significantly increased by pre-treatment for reduction of particle size. Batch-wise anaerobic digestion of sisal fibre waste was carried out in 1-l digesters with fibre sizes ranging from 2 to 100 mm, at an ambient temperature of 33 °C. Sediment from a stabilisation pond at a sisal production plant was used as starter se

A night vision brain area in migratory songbirds

Twice each year, millions of night-migratory songbirds migrate thousands of kilometers. To find their way, they must process and integrate spatiotemporal information from a variety of cues including the Earth's magnetic field and the night-time starry sky. By using sensory-driven gene expression, we discovered that night-migratory songbirds possess a tight cluster of brain regions highly active on

Treatment potential for cholesterol management in patients with coronary heart disease in 15 European countries: Findings from the EUROASPIRE II survey

Background: During the last decade, the evidence of beneficial effects of cholesterol lowering in patients with coronary heart disease (CHD) has been proven in several clinical trials. This has prompted international guidelines on prevention of CHD to include recommendations on dietary and pharmacological treatment of hyperlipidaernia with set goals on total- and LDL-cholesterol. Methods: The firs

Global patterns of gene regulation associated with the development of ectomycorrhiza between birch (Betula pendula Roth.) and Paxillus involutus (Batsch) fr.

The formation of ectomycorrhizal (ECM) root tissue is characterized by distinct morphological and developmental stages, such as preinfection and adhesion, mantle, and Hartig net formation. The global pattern of gene expression during these stages in the birch (Betula pendula)-Paxillus involutus ECM association was analyzed using cDNA microarrays. In comparison with nonsymbiotic conditions, 251 fun
