The fibrillogenic L178H variant of apolipoprotein A-I forms helical fibrils.

A number of amyloidogenic variants of apolipoprotein A-I (apoA-I) have been discovered but most have not been analyzed. Previously, we showed that the G26R mutation of apoA-I leads to increased β-strand structure, increased N-terminal protease susceptibility and increased fibril formation after several days of incubation. In vivo, this and other variants mutated in the N-terminal domain (residues

Strategies for reducing inhibitor formation in severe haemophilia

The greatest barrier to successful haemophilia A care in resource-rich countries is the development of inhibitors to therapeutic factor VIII. Children with inhibitors suffer through increased bleeding and joint damage as well as frequent venepuncture. Costs associated with inhibitors are beyond many healthcare systems. Over the last two decades, there has been no improvement in our ability to redu

Unipolar and bipolar operation of InAs/InSb nanowire heterostructure field-effect transistors

We present temperature dependent electrical measurements on n-type InAs/InSb nanowire heterostructure field-effect transistors. The barrier height of the heterostructure junction is determined to be 220 meV, indicating a broken bandgap alignment. A clear asymmetry is observed when applying a bias to either the InAs or the InSb side of the junction. Impact ionization and band-to-band tunneling is m

Contrasting effects of low and high nitrogen additions on soil CO2 flux components and ectomycorrhizal fungal sporocarp production in a boreal forest

Nitrogen (N) added through atmospheric deposition or as fertilizer to boreal and temperate forests reduces both soil decomposer activity (heterotrophic respiration) and the activity of roots and mycorrhizal fungi (autotrophic respiration). However, these negative effects have been found in studies that applied relatively high levels of N, whereas the responses to ambient atmospheric N deposition r

BDNF increases survival and neuronal differentiation of human neural precursor cells cotransplanted with a nanofiber gel to the auditory nerve in a rat model of neuronal damage.

Objectives. To study possible nerve regeneration of a damaged auditory nerve by the use of stem cell transplantation. Methods. We transplanted HNPCs to the rat AN trunk by the internal auditory meatus (IAM). Furthermore, we studied if addition of BDNF affects survival and phenotypic differentiation of the grafted HNPCs. A bioactive nanofiber gel (PA gel), in selected groups mixed with BDNF, was ap

The PSEN1 I143T mutation in a Swedish family with Alzheimer's disease: clinical report and quantification of A beta in different brain regions

Early-onset dominantly inherited forms of Alzheimer's disease (AD) are rare, but studies of such cases have revealed important information about the disease mechanisms. Importantly, mutations in amyloid precursor protein (APP), presenilin 1 (PSEN1) and PSEN2, alter the APP processing and lead to an increased amyloid beta-peptide (A beta) 42/40 ratio. This, together with other studies on pathogenic

Visual navigation in starfish: first evidence for the use of vision and eyes in starfish.

Most known starfish species possess a compound eye at the tip of each arm, which, except for the lack of true optics, resembles an arthropod compound eye. Although these compound eyes have been known for about two centuries, no visually guided behaviour has ever been directly associated with their presence. There are indications that they are involved in negative phototaxis but this may also be go

Ceramics and change. An overview of pottery production

In southern African Iron Age studies, there are few attempts to systematically apply and include laboratory analyses when studying archaeological ceramic materials. As demonstrated in this paper, such analyses help to understand technological aspects such as raw materials, manufacturing techniques and vessel function. Combined with vessel shape and decoration as well as ethnographic studies the re

Life years lost-comparing potentially fatal late complications after radiotherapy for pediatric medulloblastoma on a common scale

BACKGROUND: The authors developed a framework for estimating and comparing the risks of various long-term complications on a common scale and applied it to 3 different techniques for craniospinal irradiation in patients with pediatric medulloblastoma. METHODS: Radiation dose-response parameters related to excess hazard ratios for secondary breast, lung, stomach, and thyroid cancer; heart failure,

Abnormal atrial activation is common in patients with arrhythmogenic right ventricular cardiomyopathy.

INTRODUCTION: Structural right atrial abnormalities have been described in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, little is known about electrocardiographic signs of atrial involvement in ARVC because no systematic studies have been conducted. METHODS: P-wave-triggered signal-averaged orthogonal electrocardiogram from 40 ARVC patients (46 ± 15 years, 16 fema

Long-Term Outcome of Mustard/Senning Correction for Transposition of the Great Arteries (TGA) in Sweden and Denmark.

-The atrial switch operation Mustard- or Senning operation for transposition of the great arteries (TGA) was introduced in the late 1950s and was the preferred surgery for TGA until the early 1990s. The Mustard- and Senning operation involves extensive surgery in the atria and leaves the right ventricle as the systemic ventricle. The Mustard and Senning cohort is now well into adulthood and we beg

Between empowerment and powerlessness: Separated minors in Sweden

This article analyzes the migration experiences of thirteen separated minors who arrived in Sweden between 1943 and 2008. Using the framework of the “liberated self” this chapter shows that the experiences of separated minors are shaped in the intersection between contexts and conditions of transnational migration and the Swedish reception system. Their efforts to continue living based on the past

Systemic Lupus Erythematosus Prevalence in Sweden in 2010: What Do National Registers Say?

Objective. Worldwide prevalence estimates of systemic lupus erythematosus (SLE) range from 3 to 207 per 100,000, depending on region and population, SLE definition, case sources, and other methodologic considerations. We aimed to determine the prevalence of SLE in Sweden on January 1, 2010, using population-based registers. Methods. Linking multiple national registers, we identified all possible i

Blue laccase from Galerina sp.: Properties and potential for Kraft lignin demethylation

We purified a laccase isoenzyme, Lad 1 from Galerina sp. HC1 using a combination of anion exchange- and hydrophobic interaction chromatography. Lad l has a molecular mass of 64 kDa, an isoelectric point of 4, and 3.35 copper atoms/enzyme molecule. The enzyme has features typical of fungal blue laccases. The sequences of two internal peptides were highly similar to reported laccase sequences from o
