Objective. Helicobacter pylori infection is an established risk factor for non-cardia gastric adenocarcinoma. Infection with H. pylori strains harbouring the cagA pathology island may augment this association. H. pylori infection may at the same time reduce the risk for oesophageal carcinoma. However, prospective data on the association between CagA seropositivity and gastric or oesophageal carcin

Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable road users. The possible improvements investigated have been: a) the use of exposure data for vulnerabl

Scolecodonts, polychaete jaws, generally occur abundantly in Silurian shallow marine successions and are known from all continents except Antarctica. The assemblages are typically characterized by taxa with labidognath, placognath and prionognath type jaw apparatuses. They commonly include species of Kettnerites Zebera, 1935, Oenonites Hinde, 1879, Mochtyella Kielan-Jaworowska, 1961, Protarabellit

Objectives Exposure to aluminium compounds, such as fluorides in gaseous and particulate form, places people who work in potrooms at risk for respiratory symptoms. Workers in potrooms, however, also are exposed to a number of other air contaminants. In this study, we present the first report of a dose-response relationship after exposure to potassium aluminium tetrafluoride (KAlF4) and the influen

Eliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived

Over the last two decades there has been a striking and continuous increase in the prevalence of obesity both in industrialized and developing countries. Despite this global consistency there is a variation within countries with a higher prevalence of obesity within rural areas. The overall aim was to explore the prevalence of obesity and factors that influence the development of obesity in a rura

Studying gene-lifestyle interaction may help to identify lifestyle factors that modify genetic susceptibility and uncover genetic loci exerting important subgroup effects. Adequately powered studies with prospective, unbiased, standardised assessment of key behavioural factors for gene-lifestyle studies are lacking. This case-cohort study aims to investigate how genetic and potentially modifiable

Unique measurements of vertical size-resolved aerosol particle concentrations, trace gas concentrations and meteorological data were obtained during the Arctic Summer Cloud Ocean Study (ASCOS, www.ascos.se), an International Polar Year project aimed at establishing the processes responsible for formation and evolution of low-level clouds over the high Arctic summer pack ice. The experiment was con

Study Type - Prognosis inception (cohort) Level of Evidence 2 What's known on the subject? and What does the study add? There are two randomized controlled trials showing that radiotherapy can be beneficial for men with locally advanced prostate cancer. The present study confirms the importance of curative treatment for men with high-risk prostate cancer. OBJECTIVE: • To investigate the influen

Background: Mass screening for celiac disease (CD) as a public health intervention is controversial. Prior to implementation, acceptability to the targeted population should be addressed. We aimed at exploring adolescents' and parents' experiences of having the adolescents' CD detected through mass screening, and their attitudes towards possible future mass screening. Methods: All adolescents (n =

Background: The health status of individuals is determined by multiple factors operating at both micro and macro levels and the interactive effects of them. Measures of health inequalities should reflect such determinants explicitly through sources of levels and combining mean differences at group levels and the variation of individuals, for the benefits of decision making and intervention plannin

The role of estrogen receptor beta (ERβ) in breast cancer has been investigated since its identification in 1996. Studies based on protein expression have indicated that ERβ is a favorable prognostic marker. Further, ERβ expression is lower in obese breast cancer patients. Fewer studies have focused on the prognostic impact of ERβ polymorphisms. Therefore, we analyzed the associations between four

Relative to vascular plants, little is known about what factors control bryophyte communities or how they respond to successional and environmental changes. Bryophytes are abundant in boreal forests, thus changes in moss community composition and functional traits (for example, moisture and nutrient content; rates of photosynthesis and respiration) may have important consequences for ecosystem pro

Shelf and coastal regions are exceptionally important for many countries as they provide the main habitat for many economically important fish and shellfish species. With ongoing climate change and human-induced eutrophication the shelf regions are especially affected, resulting in increased temperatures and stratification as well as oxygen depletion of the bottom waters. In order to be able to pr

Although much attention in recent years has been devoted to methane (CH4) emissions from northern wetlands, measurement based data sets providing full annual budgets are still limited in number. This study was designed to help fill the gap of year-round measurements of CH4 emissions from subarctic mires. We report continuous eddy correlation CH4 flux measurements made during 2006 and 2007 over the
