Alzheimer's disease (AD) brain tissue can act as a seed to accelerate aggregation of amyloid-β (Aβ) into plaques in AD transgenic mice. Aβ seeds have been hypothesized to accelerate plaque formation in a prion-like manner of templated seeding and intercellular propagation. However, the structure(s) and location(s) of the Aβ seeds remain unknown. Moreover, in contrast to tau and α-synuclein, an in

Many workers are occupationally exposed to polycyclic aromatic hydrocarbons (PAHs), which may cause various health problems, and some PAHs are known or suspected carcinogens. PAH exposure is primarily monitored by air sampling, but contamination may also occur through dermal exposure. PAHs adsorbed to the skin can be sampled by tape-stripping, but subsequent extraction of sampling tapes in organic

Background: Flexible Assertive Community Treatment (Flexible ACT) has been implemented in Sweden during recent years due to increasing interest in integrated services for people with severe mental illness. To date, few studies have been done on Flexible ACT effectiveness. Aims: The overall aim of this study was to explore the extent to which clients assigned to the Flexible ACT board for ACT inten

Vi betalar för tjänster som Facebook och Google genom att dessa företag får reda på mycket om oss. Men det oerhört svårt att se hur din data används och följa vart den tar vägen. Det krävs mer öppenhet, skriver experten Stefan Larsson.

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor tem- perature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature.

The Franco-Chinese migrant woman writer Shan Sa left Beijing for Paris at the age of almost eighteen in 1990. After her settlement in France, French soon became her additional, increasingly dominant language of literary creation. This article examines Shan’s three self-acclaimed ‘historical’ novels about ancient China – Les Quatre vies du saule (Prix Cazes 1999), La Cithare nue (2010), and Impérat

This paper has re-analysed and compared data between three studies conducted in the United Kingdom and in Sweden (the OPUS ‘Older People's Use of Unfamiliar Space’ study in the United Kingdom and the Swedish studies ‘Let's Go for a Walk’ and ‘Walking in Old Age’) to provide a comprehensive account of the issues facing older people in the outdoor environment. All three studies draw on the ‘fit’ bet

Objective: To examine prenatal APAP exposure in relation to language development in offspring at 30 months of age. Method: A population-based pregnancy cohort study including 754 women who enrolled in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA) study in pregnancy week 8-13. Two exposure measures were used: (1) maternally reported number of APAP tablets take

OBJECTIVES: Depression can negatively impact work capacity, but treatment effects on sick leave and employment are unclear. This study evaluates if internet-based cognitive behavioural therapy (ICBT) or physical exercise (PE), with already reported positive effects on clinical outcome and short-term work ability, has better effects on employment, sick leave and long-term work ability compared with

I vår kropp finns en myriad av proteiner och celler med viktiga funktioner och de flesta av dem är täckta av kolhydrater. Galektiner är en familj proteiner som har en ficka där olika kolhydrater kan binda in. Genom att kolhydrater på celler eller andra proteiner binder in till denna ficka kan galektiner påverka cellulära funktioner. Vid cancer och inflammation har överproduktion av vissa galektineGalectins are a class of β-galactoside-binding proteins that bind glycoconjugates and have been implicated in cancer, regulation of immunity and inflammation. Design and synthesis have achieved highly potent and selective galectin ligands that can inhibit interactions with glycoproteins and have consequent cellular effects. These ligands can be used as tools to further elucidate the roles of galec

Background: Vitamin D is crucial for mineralized tissue formation and immunological functions. The purpose of this study was to evaluate the association between vitamin D status and dental status in healthy children with vitamin D supplementation in infancy and at 6 years of age. Method: Eight-year-old children who had participated in a vitamin D intervention project when they were 6 years old wer

For a pair of closely located and cooperating user equipments (UEs), a precoder is designed at the base station (BS) which considers the UE cooperation. The UEs collaborate over an out-of-band side-link with a finite capacity. The side-link may be used for interference cancellation (IC) or for relaying decoded symbols. The precoder has two parts, a cooperative part based on channel inversion and a

Development of single-molecule localization microscopy techniques has allowed nanometre scale localization accuracy inside cells, permitting the resolution of ultra-fine cell structure and the elucidation of crucial molecular mechanisms. Application of these methodologies to understanding processes underlying DNA replication and repair has been limited to defined in vitro biochemical analysis and

STUDY QUESTION: What is the relationship between the number of oocytes collected in fresh IVF treatments and the likelihood of cumulative delivery rate (fresh and frozen) per oocyte aspiration, severe ovarian hyperstimulation syndrome (OHSS) and thromboembolic events? SUMMARY ANSWER: Cumulative delivery rate per aspiration increases up to 20 oocytes retrieved and then evens out while the incidence
