Using ultrasound we recently demonstrated that in central elastic arteries as well as in large muscular arteries in humans there is a distinct longitudinal displacement of the arterial wall during the cardiac cycle. Further, for the first time, we also demonstrated that the inner parts of the vessel wall, the intima-media complex, in these vessels exhibit a larger longitudinal displacement than th

Hormones and neurobiological factors may be regulated differently in suicidal versus non-suicidal depressive patients. There is currently limited knowledge about the relation of substances in the Renin-Angiotensin-Aldosterone system to depression and suicidality. We therefore investigated whether plasma levels of renin and aldosterone differ between suicide attempters, non-suicidal depressive pati

Maternal enterovirus infections during pregnancy may increase the risk of offspring developing type 1 diabetes during childhood. The aim of this study was to investigate whether gestational enterovirus infections increase the offspring's risk of type 1 diabetes later in life. Serum samples from 30 mothers without diabetes whose offspring developed type 1 diabetes between 15 and 25 years of age wer

INTRODUCTION: Many competitive breath-hold divers employ the technique of glossopharyngeal insufflation in order to increase their lung gas volume for a dive. After a maximal inspiration, using the oral and pharyngeal muscles repeatedly, air in the mouth is compressed and forced into the lungs. Such overexpansion of the lungs is associated with a high transpulmonary pressure, which could possibly

PURPOSE: Tamoxifen is one of many standard therapeutic options currently available for estrogen receptor-alpha-positive breast cancer patients. Emerging data have suggested that levels of estrogen receptor coregulatory proteins play a significant role in acquiring resistance to antiestrogen action. It has been suggested that high levels of estrogen receptor coactivators and its mislocalization may

The effect of changing climatic conditions on wild populations has been the subject of much recent research. Most attention has been on the direct effects of climate changes on species of lower trophic levels and on the negative consequences of climate change. However, a deeper understanding of how climate change affects apex predators is vital, as they are keystone species that have a disproporti

Primary immunodeficiencies (IDs) are a heterogenic group of inherited disorders of the immune system. Immunodeficiency patients have increased susceptibility to recurrent and persistent, even life-threatening infections. Mutations in a large number of genes can cause defects in different cellular functions and lead to impaired immune response. To date, approximately 150 IDs and more than 100 affec

Background: General practice is a common setting for medical students' clinical training. However, little is known about patients' views on consulting with senior students. Aims: To investigate patients' attitudes to consultations conducted by senior students alone, before patients saw their GP; and to enquire into patients' perception of their teaching role. Method: Adult patients attending 50 he

BACKGROUND: The development of persistent itchy nodules at the injection site following hyposensitization therapy with aluminium-precipitated antigen extract has been described in several reports. Occasionally, contact allergy to aluminium has been reported in individuals with such nodules. OBJECTIVES: To investigate if hyposensitization therapy can induce contact allergy to aluminium and examine

New non-invasive techniques enabling frequent or continuous assessments of various pathophysiological conditions might be used to improve in-hospital outcome by enabling earlier and more reliable bedside detection of medical deterioration. In this preclinical study, three modern non-invasive optical techniques, laser Doppler imaging (LDI), near-infrared spectroscopy (NIRS), and tissue viability im

Introduction ECG stress testing is an inexpensive and non-invasive detector of myocardial ischemia; addition of high-frequency QRS analysis (HFQRS) may improve accuracy. This study compared HFQRS during exercise in patients with and without ischemia as defined by multiple criteria. Material and methods High-resolution ECGs were recorded for 139 patients undergoing T99-sestamibi/T201-thallium stre

The aim of this paper is to describe and analyse the repurposing of Facebook into a tool for learning in teacher training, and how information literacies are enacted in the process. The study is informed by a socio-cultural view on information literacy which implies that learning and literacies are situated, tool-based practices. An ethnographic study of a Facebook Group with two hundred Swedish

Single nucleotide polymorphisms (SNPs) are the most common form of genetic variation in humans. The number of SNPs identified in the human genome is growing rapidly, but attaining experimental knowledge about the possible disease association of variants is laborious and time-consuming. Several computational methods have been developed for the classification of SNPs according to their predicted pat

Anaplastic thyroid cancer (ATC) is a rare but highly aggressive disease with largely unexplained etiology and molecular pathogenesis. In this study, we analyzed genome-wide copy number changes, BRAF (V-raf sarcoma viral oncogene homolog B1) mutations, and p16 and cyclin D1 expressions in a panel of ATC primary tumors. Three ATCs harbored the common BRAF mutation V600E. Using array-comparative geno

The crucial role of dopamine (DA) in movement control is illustrated by the spectrum of motor disorders caused by either a deficiency or a hyperactivity of dopaminergic transmission in the basal ganglia. The degeneration of nigrostriatal DA neurons in Parkinson's disease causes poverty and slowness of movement. These symptoms are greatly improved by pharmacological DA replacement with l-3,4-dihydr

Goniometry of the wrist is a feasible method for studying wrist movements in most hand-intensive work. The precision and accuracy of the method per se is good. For the knowledge on validity of field measurements, the size of imprecision is of importance. This study evaluated this condition during standardized circumstances. Six women performed three different hand-intensive work tasks: 'materials
