Leisure-time physical activities and the risk of cardiovascular mortality in the Malmö diet and Cancer study

BACKGROUND: The association between leisure-time physical activity and cardiovascular mortality has been previously studied, but few studies have focused on specific activities and intensities.METHODS: The association between different leisure-time physical activities and cardiovascular mortality was investigated among 25,876 individuals without diabetes or cardiovascular disease from the populati

Improving texture and microstructure homogeneity in high-purity ta sheets by warm cross rolling and annealing

The evolution of texture and microstructure uniformity in high-purity tantalum (Ta) sheets during 135◦ warm cross rolling (WCR) was analyzed in detail. X-ray diffraction suggested that relatively uniform ‘ideal’ deformation texture distribution across the thickness could be obtained from WCR, since more potential slip systems could be activated. Electron backscatter diffraction (EBSD) results indi

Anaeramoebae are a divergent lineage of eukaryotes that shed light on the transition from anaerobic mitochondria to hydrogenosomes

Discoveries of diverse microbial eukaryotes and their inclusion in comprehensive phylogenomic analyses have crucially re-shaped the eukaryotic tree of life in the 21st century.1 At the deepest level, eukaryotic diversity comprises 9-10 "supergroups." One of these supergroups, the Metamonada, is particularly important to our understanding of the evolutionary dynamics of eukaryotic cells, including

Block Copolymer Nanolithography for Sub-50 nm Structure Applications

När de kritiska mönsterdimensionerna för högteknologiska enheter fortsätter krympa och mönstertätheten fortsätter öka, behöver även litografin att gå i samma riktning. En lovande teknologi är sampolymerlitografi, som har en upplösning under 10 nm, en mönsterperiodicitet omkring 7-200 nm, och lätt kan skalas upp till större ytor till en låg kostnad. Användandet av sampolymerer där de ingående blockAs high technology device patterns are continuing to move towards decreasing critical dimensions and increasing pattern density, there is a need for lithography to move in the same direction. Block copolymer (BCP) lithography is a promising technique, which has single digit nanometer resolution, has a pattern periodicity of about 7-200 nm, and easily scales up to large area at a low cost. The use

Thermistor-based biosensing

In this review a universal thermistor-based biosensor system is described with examples from clinical chemistry, bioprocess monitoring and environmental control. The technique is based on the measurement of the small temperature changes associated with enzymatic reactions occurring in a microreactor with immobilized enzyme. The system has good operational stability and a sensitivity that permits m

Reality shifting: psychological features of an emergent online daydreaming culture

Reality shifting (RS) is a trendy mental activity that emerged abruptly following the flare-up of the COVID-19 pandemicin 2020 and seems to be practiced mainly by members of the post-millennial generation. RS, described as the experience ofbeing able to transcend one’s physical confines and visit alternate, mostly fictional, universes, is discussed by many on Internetplatforms. One RS forum boasts

Haemoglobin and red blood cell reference intervals during infancy

OBJECTIVES: There is a need for updated haematological reference data in infancy. This study aimed to define intervals for haemoglobin and red blood cell biomarkers based on data from a large cohort of longitudinally followed Swedish infants. DESIGN: Longitudinal cohort study. SETTING: Two Swedish study centres. PARTICIPANTS: Three community-based populations including 442 presumably healthy infan

It's much more grey than black and white : clinical geneticists' views on the oversight of consumer genomics in Europe

Aim: Direct-to-consumer (DTC) genetic tests (GT) have created controversy regarding their risks and benefits. In view of recent regulatory developments, this article aims to explore the attitudes of European clinical geneticists toward the oversight of DTC GT. Materials & methods: Fifteen semi-structured interviews were performed with clinical geneticists based in ten European countries. The t

How to responsibly acknowledge research work in the era of big data and biobanks : ethical aspects of the Bioresource Research Impact Factor (BRIF)

Currently, a great deal of biomedical research in fields such as epidemiology, clinical trials and genetics is reliant on vast amounts of biological and phenotypic information collected and assembled in biobanks. While many resources are being invested to ensure that comprehensive and well-organised biobanks are able to provide increased access to, and sharing of biomedical samples and information

Direct-to-consumer genetic testing : where and how does genetic counseling fit?

Direct-to-consumer genetic testing for disease ranges from well-validated diagnostic and predictive tests to 'research' results conferring increased risks. While being targeted at public curious about their health, they are also marketed for use in reproductive decision-making or management of disease. By virtue of being 'direct-to-consumer' much of this testing bypasses traditional healthcare sys

The challenges of the expanded availability of genomic information : an agenda-setting paper

Rapid advances in microarray and sequencing technologies are making genotyping and genome sequencing more affordable and readily available. There is an expectation that genomic sequencing technologies improve personalized diagnosis and personalized drug therapy. Concurrently, provision of direct-to-consumer genetic testing by commercial providers has enabled individuals' direct access to their gen

DeveLoP—A Rationale and Toolbox for Democratic Landscape Planning

A rationale for an individuals-oriented landscape approach to sustainable land-use planning based on an analysis of bio-geo-physical components as well as the human components of the landscape is presented. A toolbox for analysing individuals’ decision-making and valuations in the landscape is described. The toolbox can provide evidence on the drivers of individuals’ decision-making in the landsca

Regulating the advertising of genetic tests in Europe : a balancing act

Direct-to-consumer (DTC) genetic tests (GT) have provoked criticism over their potential adverse impact on public health. The European Parliament called for a ban on DTC advertising of GT during the debate for the adoption of a European Regulation on in vitro diagnostic medical devices. This proposal, however, was not ultimately retained in the final text. Instead, the regulation includes an artic

Whole-genome sequencing in newborn screening? : A statement on the continued importance of targeted approaches in newborn screening programmes

The advent and refinement of sequencing technologies has resulted in a decrease in both the cost and time needed to generate data on the entire sequence of the human genome. This has increased the accessibility of using whole-genome sequencing and whole-exome sequencing approaches for analysis in both the research and clinical contexts. The expectation is that more services based on these and othe

Ethical issues raised by whole genome sequencing

While there is ongoing discussion about the details of implementation of whole genome sequencing (WGS) and whole exome sequencing (WES), there appears to be a consensus amongst geneticists that the widespread use of these approaches is not only inevitable, but will also be beneficial [1]. However, at the present time, we are unable to anticipate the full range of uses, consequences and impact of i

Is There a Right Time to Know? : The Right Not to Know and Genetic Testing in Children

The increasing implementation of next-generation sequencing technologies in the clinical context and the expanding commercial offer of genetic tests directly-toconsumers has increased the availability of previously inaccessible genetic information. A particular concern in both situations is how the volume of novel information will affect the processing of genetic and genomic information from minor
