Mapping energy transfer channels in fucoxanthin-chlorophyll protein complex.

Fucoxanthin-chlorophyll protein (FCP) is the key molecular complex performing the light-harvesting function in diatoms, which, being a major group of algae, are responsible for up to one quarter of the total primary production on Earth. These photosynthetic organisms contain an unusually large amount of the carotenoid fucoxanthin, which absorbs the light in the blue-green spectral region and trans

Effects of glazing colour type on perception of daylight quality, arousal, and switch-on patterns of electric light in office rooms

A study is presented about the effects of three glazing colour types (blue, neutral, bronze) on daylight quality, arousal and switch-on patterns for electric lights. This study was carried out using a scale model (1:4) of an office room, where subjective evaluations of the luminous conditions were performed by 36 participants (mean age 23.8 years) with their upper bodies immersed in the model. The

Sexual debut before the age of 14 leads to poorer psychosocial health and risky behaviour in later life

Aim: This study investigated the relationship between sexual debut before 14 years of age and socio-demographics, sexual experience, health, experience of child abuse and behaviour at 18 years of age. Methods: A sample of 3432 Swedish high school seniors completed a survey about sexuality, health and abuse at the age of 18. Results: Early debut was positively correlated with risky behaviours, such

Perivascular mesenchymal stem cells in the adult human brain: a future target for neuroregeneration?

Perivascular adult stem cells have been isolated from several tissues, including the adult human brain. They have unique signatures resembling both pericytes and mesenchymal stem cells. Understanding the nature of these cells in their specific vascular niches is important to determine their clinical potential as a new adult stem cell source. Indeed, they have promising features in vitro in terms o

Sexuality in diasporic space: rural-to-urban migrant women negotiating gender and marriage in contemporary China

Feminist geographers use the term diasporic subjectivity to emphasize the relational quality of identity as it is constructed in the dynamic in-between space occupied by the migrant and traversed by norms and practices associated with the village community, migrant peers, and urban consumer society, as well as nation-states. Using ethnographic methods, I explore how young, single rural Chinese wom

Spatial analysis of diffusion tensor tractography statistics along the inferior fronto-occipital fasciculus with application in progressive supranuclear palsy

The purpose of the study was to develop a method for analysis of diffusion parameters along white matter (WM) tracts, using spatial normalization based on anatomical landmarks, and to introduce the apparent area coefficient (AAC). The method's applicability was tested in the inferior fronto-occipital fasciculus (IFO) in patients with progressive supranuclear palsy (PSP) and healthy controls (HCs).

Combined impact of healthy lifestyle factors on colorectal cancer: a large European cohort study

Background: Excess body weight, physical activity, smoking, alcohol consumption and certain dietary factors are individually related to colorectal cancer (CRC) risk; however, little is known about their joint effects. The aim of this study was to develop a healthy lifestyle index (HLI) composed of five potentially modifiable lifestyle factors healthy weight, physical activity, non-smoking, limited

Commodifying Danish housing commons

Housing was a backbone of the Danish welfare state, but this has been profoundly challenged by the past decades of neoliberal housing politics. In this article we outline the rise of the Danish model of association-based housing on the edge of the market economy (and the state). From this, we demonstrate how homes in private cooperatives through political interventions in the context of a booming

Effects of stream predator richness on the prey community and ecosystem attributes.

It is important to understand the role that different predators can have to be able to predict how changes in the predator assemblage may affect the prey community and ecosystem attributes. We tested the effects of different stream predators on macroinvertebrates and ecosystem attributes, in terms of benthic algal biomass and accumulation of detritus, in artificial stream channels. Predator richne

Prediction of 30-day Mortality after Transcatheter Aortic Valve Implantation: A Comparison of Logistic EuroSCORE, STS score, and EuroSCORE II

Background and aim of the study: The logistic EuroSCORE and STS score have been used for the selection of suitable TAVI patients, but their predictive ability is unsatisfactory. The study aim was to evaluate the performance of the EuroSCORE II in predicting 30-day mortality after TAVI in comparison to the logistic EuroSCORE and STS scoring systems. Methods: Between January 2008 and April 2013, a t

Inhibition of Amyloid beta Protein Fibrillation by Polymeric Nanoparticles

Copolymeric NiPAM:BAM nanoparticles of varying hydrophobicity were found to retard fibrillation of the Alzheimer's disease-associated amyloid beta protein (A beta). We found that these nanoparticles affect mainly the nucleation step of A beta fibrillation. The elongation step is largely unaffected by the particles, and once the M is nucleated, the fibrillation process occurs with the same rate as

Autofluorescence imaging videoendoscopy in the diagnosis of chronic atrophic fundal gastritis

Purpose: Diagnosis of chronic atrophic fundal gastritis (CAFG) is important to understand the pathogenesis of gastric diseases and assess the risk of gastric cancer. Autofluorescence imaging videoendoscopy (AFI) may enable the detection of mucosal features not apparent by conventional white-light endoscopy. The purpose of this study was to estimate the diagnostic ability of AFI in CAFG. Methods: A

Enhanced organic mass fraction and decreased hygroscopicity of cloud condensation nuclei (CCN) during new particle formation events

In a forested near-urban location in central Germany, the CCN efficiency of particles smaller than 100 nm decreases significantly during periods of new particle formation. This results in an increase of average activation diameters, ranging from 5 to 8% at supersaturations of 0.33% and 0.74%, respectively. At the same time, the organic mass fraction in the sub-100-nm size range increases from appr

Patients with Osteoarthritis in all Three Knee Compartments and Patients with Medial Knee Osteoarthritis Have a Phenotype with High Bone Mass and High Fat Mass but Proportionally Low Lean Mass.

Cross-sectional studies have shown that patients with primary hip osteoarthritis (OA) have higher bone mineral density (BMD), higher BMI, lower lean body mass, and higher fat content. But it is unknown if this phenotype is found also in patients with knee OA and if it precedes OA or manifests as a result of the disease.

"We are in the Congo now" : Sweden and the trinity of peacekeeping during the Congo crisis 1960-1964

his work examines the contemporaneous Swedish experience from participation in the United Nations operation in the Congo, ONUC, from 1960 to 1964. Inspired by Carl von Clausewitz’s understanding of war as a trinity consisting of three ‘nodes’: the political authority, the people and the military, this study focuses on the ONUC experience as described by the government in Sweden, leading Swedish ne
