Molecular spiders are synthetic molecular motors featuring multiple legs that each can interact with a substrate through binding and cleavage. Experimental studies suggest the motion of the spider in a matrix is biased toward uncleaved substrates and that spider properties such as processivity can be altered by changing the binding strength of the legs to substrate [R.

Cognitive ability strongly aggregates in families, and prior twin and adoption studies have suggested that this is the result of both genetic and environmental factors. In this study, we used a powerful design-home-reared and adopted-away cosibling controls-to investigate the role of the rearing environment in cognitive ability. We identified, from a complete national Swedish sample of male-male s
Background: The role of estrogen and progesterone in the development of endometrial cancer is well documented. Few studies have examined the association of genetic variants in sex hormone-related genes with endometrial cancer risk. Methods: We conducted a case-control study nested within three cohorts to examine the association of endometrial cancer risk with polymorphisms in hormone-related genes
OBJECTIVES: We examined whether the association between hormone therapy (HT) use and coronary heart disease (CHD) risk differed between women with and without vasomotor symptoms (VMS). STUDY DESIGN: We used data from a Dutch (EPOS) and Swedish (WHILA) population-based sample of 8865 women, aged 46-64 years, and free of CHD, stroke, venous thrombosis/pulmonary embolism or cancer at baseline. Data o
Moderate alcohol consumption has been suggested to protect against venous thromboembolism (VTE). However, it is not known how alcohol abuse and its associated somatic complications affect the risk of VTE. The present study determined the risk of pulmonary embolism (PE) and deep vein thrombosis (DVT) of the lower extremities in patients with alcohol use disorders (AUDs) in Sweden. All inpatients wi
Many men with elevated prostate-specific antigen (PSA) levels in serum do not have aggressive prostate cancer and undergo unnecessary biopsy. Retrospective studies using cryopreserved serum suggest that four kallikrein markers can predict biopsy outcome.
Vibrationally resolved valence-shell photoionization spectra of H(2), N(2) and CO have been measured in the photon energy range 20-300 eV using third-generation synchrotron radiation. Young's double-slit interferences lead to oscillations in the corresponding vibrational ratios, showing that the molecules behave as two-center electron-wave emitters and that the associated interferences leave their
Mental disorders are associated with premature mortality, and the magnitudes of risk have commonly been estimated using hospital data. However, psychiatric patients who are hospitalized have more severe illness and do not adequately represent mental disorders in the general population. We conducted a national cohort study using outpatient and inpatient diagnoses for the entire Swedish adult popula
IMPORTANCE Peer deviance (PD) strongly predicts externalizing psychopathologic conditions but has not been previously assessable in population cohorts. We sought to develop such an index of PD and to clarify its effects on risk of drug abuse (DA). OBJECTIVES To examine how strongly PD increases the risk of DA and whether this community-level liability indicator interacts with key DA risk factors a
Background: Genetic counselling and testing for Lynch syndrome have recently been introduced in several South American countries, though yet not available in the public health care system. Methods: We compiled data from publications and hereditary cancer registries to characterize the Lynch syndrome mutation spectrum in South America. In total, data from 267 families that fulfilled the Amsterdam c
The aim of this study was to estimate the prevalence and incidence of mood disorders, anxiety disorders, and stress and adjustment disorders in primary health care in Sweden and to analyse the relationship between socioeconomic and demographic factors and incidence of these disorders. Prevalence and incidence data on the study population was retrieved from a Swedish primary health care database. A
Throughout the Western world, response rates are falling in population surveys. The aim of the study was to explore for the presence of non-response bias in two Swedish research projects on HIV ['HIV in Sweden' (HIS11)] and sexuality ['Sex and health' (UngKAB09)].
Little is known about the association between neighborhood linking social capital and psychiatric medication in the elderly. The present study analyzes whether there is an association between linking social capital (a theoretical concept describing the amount of trust between individuals and societal institutions) and prescription of antipsychotics, anxiolytics, hypnotics/sedatives, antidepressant
Polytypism in III-V semiconductor nanowires is a topic that has received considerable attention in recent years. Achieving a pure nanowire crystal phase requires well-controlled and advanced parameter tuning for most III-V materials. Additionally, the new and unusual phases sometimes observed may present unique material properties if they can be controllably fabricated. With the prospect of using
Recent reports on adult fracture epidemiology have focused mainly on the hip in elderly where increasing rates lately have changed to a decline. New reports of the preponderance of non-hip fractures in expenditure call for a wider scope. We therefore examined current overall and site-specific fracture epidemiology in adults. We ascertained all fractures diagnosed in in- and out-patient care in all
Lymph node dissection (LND) in prostate cancer patients may increase complications. An association of LND with thromboembolic events has been suggested. We compared the incidence and investigated predictors of deep venous thrombosis (DVT) and pulmonary embolism (PE) among other complications in patients undergoing or not undergoing LND during open (ORP) and robot-assisted laparoscopic radical pros
Objective: To describe non-lymphoma hematological malignancies in systemic lupus erythematosus (SLE). Methods: A large SLE cohort was linked to cancer registries. We examined the types of non-lymphoma hematological cancers. Results: In 16,409 patients, 115 hematological cancers [including myelodysplastic syndrome (MDS)] occurred. Among these, 33 were non-lymphoma. Of the 33 non-lymphoma cases, 13
BACKGROUND: Previous studies have found insomnia and long sleep duration to be independently associated with subsequent disability pension (DP). However, the issue of a possible gender-based pattern in this context has received little attention. PURPOSE: This study aims to assess the impact of insomnia symptoms and sleep duration on the DP rates among Swedish women and men during a 12-year follow-
