Several studies suggest that hormonal mechanisms may be associated with the development of uveal melanoma. Therefore, the association between the risk of uveal melanoma and exposure to hormonal exposures was investigated in a case-control study from nine European countries. Incident cases of uveal melanoma were frequency-matched to population and hospital controls by country, age, and sex. Female
When exposed to intermediate glucose concentrations (6-16 mol/l), pancreatic beta-cells in intact islets generate bursts of action potentials (superimposed on depolarised plateaux) separated by repolarised electrically silent intervals. First described more than 40 years ago, these oscillations have continued to intrigue beta-cell electrophysiologists. To date, most studies of beta-cell ion channe
Genetic studies have implicated the neuronal ubiquitin C-terminal hydrolase (UCH) protein UCH-L1 in Parkinson's disease (PD) pathogenesis. Moreover, the function of UCH-L1 may be lost in the brains of PD and Alzheimer's disease patients. We have previously reported that the UCH-L1 polymorphic variant S18Y, potentially protective against PD in population studies, demonstrates specific antioxidant f
Scatter-hoarding passerine birds have become a model system for research on spatial memory capacity. This research has focussed on two families, the Corvidae (crows, jays, nutcrackers, etc.) and the Paridae (titmice and chickadees). Corvids are considered to have highly developed cognitive skills that sometimes have been compared with the great apes. Even though pilfering, or stealing of caches ma
The presence of different time scales in a dynamic model significantly hampers the efficiency of its simulation. In multibody systems the fact is particularly relevant, as the mentioned time scales may be very different, due for example to the coexistence of mechanical components controlled by electronic drive units, and may also appear in conjunction with significant nonlinearities. This paper pr
BACKGROUND: Interventions aimed at reducing the number of smokers are generally believed to be cost effective. However as the cost of the interventions should be paid up front whereas the gains in life years only appear in the future--the budgetary consequences might be a barrier to implementing such interventions. AIMS: The aim of the present paper was to assess the long-term cost effectiveness
Dietary fibre and whole grains are recommended to prevent the development of type 2 diabetes. Low glycaemic index foods that are rich in fibre are recommended to control blood glucose levels. Gastric emptying, together with other factors, regulate the postprandial blood glucose response. A delay in the gastric emptying rate (GER) leads to a lower postprandial blood glucose concentration. However,
The article discusses the identity, roles, and duties of the professional historian in an era in which the historical dimension is no longer a historian's monopoly. It is argued that the standard modern framework of understanding a historian as someone highly specialized in the production of 'new' history has to give way to a new understanding that situates the historian in historical culture, whi
In order to ensure that ovarian cancer patients access appropriate treatment to improve the outcome of this disease, accurate characterization before any surgery on ovarian pathology is essential. The International Ovarian Tumor Analysis (IOTA) collaboration has standardized the approach to the ultrasound description of adnexal pathology. A prospectively collected large database enabled previously
Popular Abstract in Swedish Syftet med denna studie var att undersöka hur tvångsvård av alkoholmissbrukare upplevs av den som döms till det. Majoriteten av dessa personer är negativa till tvångsvård. I studien har också tagits hänsyn till att resultaten ses utifrån ett bredare perspektiv. Det som också undersökts är alkoholmissbruk generellt, varför klienterna dricker i den utsträckning de gör samThe aim of this study was to investigate how compulsary treatment of alcohol abuse is experienced by persons forced to submit to it, the majority of whom are negative in their attitude toward treatment of this sort. The importance of considering the resluts obtained not in isolation but within a larger context is emphasized. Among the elements of this context examined are alcohol abuse generally,
Twenty-eight haemodialysis patients were randomized to L-carnitine, 2 g i.v. three times a week, and saline over a 6-week period. No obvious deficiency of carnitine was found in vastus lateralis with a median value of 12.9 mmol/kg dry weight; range 6.2-21.4. Female patients had lower total plasma carnitine compared to female controls, p less than 0.002, whereas no decrease was found in males. No r
Objectives: To determine the direction and magnitude of participation bias in end-of-life research. Methods: Within the framework of a European survey on medical end-of-life decisions, a non-response study was conducted among physicians in Denmark, the Netherlands, Sweden and Switzerland. People were asked about their attitudes and experiences in the area of medial end-of-life decision. The respon
The purpose of this study was to explore neuroretinal transplantation in a large animal model of severe retinitis pigmentosa and to establish graft development, long-term survival, graft-host integration, and effects on the host retina. Methods Rhodopsin transgenic pigs, aged 6 months, received in one eye a fetal full-thickness neuroretinal sheet in the subretinal space by means of vitrectomy and
OBJECTIVE - To elucidate whether family characteristics and stressful life events were associated with onset of autoimmune type 1 diabetes in young adults. RESEARCH DESIGN AND METHODS - This investigation was based on a nation-wide study (Diabetes Incidence Study in Sweden) of newly diagnosed patients aged 15-34 years. Patients clinically classified as type 1 diabetic with antibodies to islet cell
This essay focuses on the reception of Pauline ideas in the Pseudo-Clementine Homilies, commonly dated to the early fourth century. At first, the claim that the Pseudo-Clementine Homilies contain Pauline ideas may seem surprising, since the Homilies are commonly considered “Jewish Christian” and thus anti-Pauline. However, new readings of Paul generated by the “Paul within Judaism” perspective, al
Lake–atmosphere carbon exchanges can be significantly affected by photochemical dissolved organic matter (DOM) mineralization. However, our understanding of how increasing allochthonous organic carbon input affects the photoreactivity of DOM per unit of absorbed incoming light is incomplete. Here, we measured the absorption of ultraviolet (UV) light and subsequent photochemical DOM decay in 148 la
Sexual activity online may result in positive experiences for young people, or lead them to engage in risky behaviours possibly resulting in sexual assault or abuse. The aim of our study was to investigate associations between online sexual behaviours among Swedish youth and background factors as well as aspects of wellbeing. The behaviours investigated were: having sex online with a contact met o
Internationalisation of higher education is a strategic theme in current research on higher education and policy debate. Both at national and institutional levels, in many countries, internationalisation is stated to be an educational goal. However, the dominant discourse on internationalisation of higher education in research and research-based discussions tends to be framed by political, economi
