The elucidation of the molecular mechanisms by which soluble proteins convert into their amyloid forms is a fundamental prerequisite for understanding and controlling disorders that are linked to protein aggregation, such as Alzheimer's and Parkinson's diseases. However, because of the complexity associated with aggregation reaction networks, the analysis of kinetic data of protein aggregation to

Attention-deficit/hyperactivity disorder (ADHD) predisposes to drug abuse (DA) and twin studies suggest shared genetic effects. We here seek to determine, using adoption and adoption-like samples, the magnitude of the cross-generational transmission from DA in parents to ADHD in their children and clarify the degree to which this arises from genetic v. rearing effects.

Purpose: Orthostatic hypotension (OH) is common and increases with age. OH is part of the autonomic dysfunction in dementia with Lewy bodies (DLB). Commonly OH is diagnosed when the patient falls which is a risk factor of premature death. Our objective was to systematically investigate the clinical symptoms associated with measurement of OH in different neurodegenerative dementias and normal contr

Genetic variants associated with venous thromboembolism (VTE) have been suggested to be involved in the pathogenesis of pre-eclampsia/eclampsia (PEC/EC). This nationwide study aimed to determine whether VTE shares familial susceptibility with PEC/EC.

Amyloid diseases are defined by tissue deposition of insoluble, fibrillar beta-sheet polymers of specific proteins, but it appears that toxic oligomeric species rather than the fibrils are the main cause of tissue degeneration. Many proteins can form amyloid-like fibrils in vitro, but only similar to 30 proteins have been found to cause mammalian amyloid disease, suggesting that physiological mech

We aimed to estimate stratified absolute (cumulative) and relative (standardized incidence ratios; SIRs) risks of non-Hodgkin lymphoma (NHL) in relatives of NHL patients. A cohort of 169 830 first-degree relatives of 45 406 NHL patients who were diagnosed between 1955 and 2010 in five European countries was followed for cancer incidence. The lifetime (0-79 year) cumulative risk of NHL in siblings

AIMS/HYPOTHESIS: Type 2 diabetes is a chronic metabolic disorder associated with devastating microvascular complications. Genome-wide association studies have identified more than 60 genetic variants associated with type 2 diabetes and/or glucose and insulin traits, but their role in the progression of diabetes is not established. The aim of this study was to explore whether these variants were al

We assessed blood pressure (BP) trends in patients with type 2 diabetes from a national diabetes register using three cross-sectional samples (aged 30-85 years) in 2005, 2007 and 2009, and in patients from 2005 followed individually until 2009. The prevalence of hypertension was 87% among all 180 369 patients in 2009, although lower in subgroups with ages 30-39, 40-49 and 50-59 years: 40%, 60% and

Purpose: To assess performance of a biomarker-based score that predicts the five-year risk of diabetes (Diabetes Risk Score, DRS) in an independent cohort that included 15-year follow-up. Method: DRS was developed on the Inter99 cohort, and validated on the Botnia cohort. Performance was benchmarked against other risk-assessment tools comparing calibration, time to event analysis, and net reclassi

BACKGROUND: Stroke is common in cancer patients, but risk estimates for different cancer sites/types have not been determined. The aim of this nationwide study was to examine whether there is an association between cancer and first hospitalisation for haemorrhagic or ischaemic stroke. METHODS: All 820,491 individuals in Sweden with a diagnosis of cancer between 1st January 1987 and 31st December 2

MIG/CXCL9 belongs to the CXC family of chemokines and participates in the regulation of leukocyte-trafficking and angiogenesis. Certain chemokines, including human MIG/CXCL9, exert strong antibacterial activity in vitro, although the importance of this property in vivo is unknown. In the present study, we investigated the expression and a possible role for MIG/CXCL9 in host defense during mucosal

This article presents a protocol for assessing team performance in terms of control based on cognitive systems engineering theory. The protocol changes the focus of team performance assessment from good and bad behaviours towards team activity. By using Hollnagel’s contextual control model (COCOM), a protocol is developed so that team activity can be described as four control modes. Data is collec

The complement system has vital protective functions as a humoral component of the innate immune system and also through interactions with the adaptive immune system; however, when inappropriately activated or regulated, complement can cause inflammation and organ damage, and such processes are involved in the pathogenesis of many inflammatory conditions, not least rheumatic diseases. Furthermore,

There are ethnic differences in the incidence of venous thromboembolism. This is the first nationwide study to examine whether there is an association between country of birth in first-generation immigrants and first hospitalisation for venous thrombosis (VT) and pulmonary embolism (PE), and to study whether a similar association exists in second-generation immigrants.

The incidences of both type 1 diabetes (T1D) and T2D are increasing worldwide. T2D is associated with many cancers. However, no data are available on cancer of unknown primary (CUP), a relatively common, fatal cancer for which tobacco smoking is the only known risk factor. At diagnosis, CUP metastases are found in various organs, which has implications for prognosis. We carried out a nationwide st

It is uncertain whether the incidence of stroke is increased in patients with chronic obstructive pulmonary disease (COPD), and whether COPD is associated with all subtypes of stroke (i.e. ischemic stroke, intracerebral haemorrhage and subarachnoid haemorrhage). We evaluated the association between COPD and incidence of stroke in a nation-wide cohort study. All individuals between 40 and 84 years

Psychosocial stress in adulthood is associated with a higher risk of type 2 diabetes, possibly mediated by behavioural and physiological factors. However, it is unknown whether low stress resilience earlier in life is related to subsequent development of type 2 diabetes. We examined whether low stress resilience in late adolescence is associated with an increased risk of type 2 diabetes in adultho

Switching of the group-III element in III-V nanowire heterostructures is difficult due to the high solubility of group-III atoms in the Au seed particle. In addition, switching from Sb to a different group-V element has not been achieved in binary materials, largely due to its high solubility in Au. In MOVPE growth the use of Sb precursors presents further complications due to reactor background c
