Disease progression and costs of care in Alzheimer's disease patients treated with donepezil: a longitudinal naturalistic cohort.

BACKGROUND/AIMS: Improved data and methods are needed for modeling disease progression in Alzheimer's disease (AD) for economic evaluation of treatments. The aim is to estimate prediction models for long-term AD progression and subsequently economic outcomes. METHODS: Three-year follow-up data on 435 patients treated with the cholinesterase inhibitor donepezil in clinical practise were analyzed.

Intensive agriculture reduces soil biodiversity across Europe

Soil biodiversity plays a key role in regulating the processes that underpin the delivery of ecosystem goods and services in terrestrial ecosystems. Agricultural intensification is known to change the diversity of individual groups of soil biota, but less is known about how intensification affects biodiversity of the soil food web as a whole, and whether or not these effects may be generalized acr

Standard Guidelines for the Chromosome-Centric Human Proteome Project

The objective of the international Chromosome-Centric Human Proteome Project (C-HPP) is to map and annotate all proteins encoded by the genes on each human chromosome. The C-FIPP consortium was established to organize a collaborative network among the research teams responsible for protein mapping of individual chromosomes and to identify compelling biological and genetic mechanisms influencing co

Increased serum type I interferon activity in early systemic sclerosis patients is associated with antibodies against Sjögren's syndrome antigens and nuclear ribonucleoprotein antigens.

Objective: To study serum type I interferon (IFN) activity in patients with early systemic sclerosis (SSc). Method: Serum type I IFN activity was measured in 33 consecutive patients with SSc and a disease duration of < 2 years and in 13 healthy individuals by calculating a type I IFN score according to the induction of six IFN-α regulated genes in a reporter cell line. Results: Twenty-seven per ce

Regime shifts in shallow lakes: the importance of seasonal fish migration

Shallow eutrophic lakes commonly exist in two alternative stable states: a clear-water state and a turbid water state. A number of mechanisms, including both abiotic and biotic processes, buffer the respective states against changes, whereas other mechanisms likely drive transitions between states. Our earlier research shows that a large proportion of zooplanktivorous fish populations in shallow l

European Union funded project on the development of a whole complement deficiency screening ELISA-A story of success and an exceptional manager: Mohamed R. Daha.

A whole complement ELISA-based assay kit, primarily designed to screen for deficiencies in components of the complement system was developed during a European Union grant involving more than a dozen European scientists and a small-medium enterprise company (Wieslab, which later merged into Eurodiagnostica). The consortium was led by Prof. Mohamed R. Daha who had already guided a preceding European

Glucocorticoids improve erythroid progenitor maintenance and dampen Trp53 response in a mouse model of Diamond-Blackfan anaemia.

Diamond-Blackfan anaemia (DBA) is a rare congenital disease causing severe anaemia and progressive bone marrow failure. The majority of patients carry mutations in ribosomal proteins, which leads to depletion of erythroid progenitors in the bone marrow. As many as 40% of all DBA patients receive glucocorticoids to alleviate their anaemia. However, despite their use in DBA treatment for more than h

Willingness to pay for wholesome canteen takeaway

The primary objective of this study was to estimate the willingness to pay (WTP) for a new intervention at the workplace: wholesome canteen takeaways (CTA), i.e. a low fat meal with a large amount of vegetables prepared at the workplace canteen that only requires re-heating. The contingent valuation method was used to elicit the WTP. Two surveys were carried out in Denmark; one large-scale Interne

Financial Development and Sustainable Exports: Evidence from Firm-product Data

We combine a novel measure of export-related financial needs at the product level with a unique database of firm-product export data (including names of the exporting firms) from five developing countries. Using the tools of survival analysis and taking into account firms’ and products’ heterogeneity, we then examine the impact of financial development on the long-term trade. Finance matters for s

Dopant Concentration and Short-Range Structure Dependence of Diffusional Proton Dynamics in Hydrated BaInxZr1-xO3-x/2 (x=0.10 and 0.50)

We investigate proton self-dynamics in the acceptor-doped and hydrated proton-conducting perovskite-type oxides BaInxZr1-xO3-x/2 (x = 0.10 and 0.50) on a microscopic length scale for temperatures in the range 470-525 K, using neutron spin-echo spectroscopy. For the highly doped material (x = 0.50), we observe a wide range of translational diffusional rates of the protons in the Structure, oil the

Treatment of Parkinson's disease using cell transplantation.

The clinical trials with intrastriatal transplantation of human fetal mesencephalic tissue, rich in dopaminergic neurons, in Parkinson's disease (PD) patients show that cell replacement can work and in some cases induce major, long-lasting improvement. However, owing to poor tissue availability, this approach can only be applied in very few patients, and standardization is difficult, leading to wi

Calcium efflux of plasma membrane vesicles exposed to ELF magnetic fieldsutest of a nuclear magnetic resonance interaction model

The question whether very weak, low frequency magnetic fields can affect biological matter is still under debate. The theoretical possibility of such an interaction is often questioned and the site of interaction in the cell is unknown. In the present study, the influence of extremely weak 60?Hz magnetic fields on the transport of Ca2+ was studied in a biological system consisting of highly purifi

The cocaine- and amphetamine-regulated transcript mediates ligand-independent activation of ER alpha, and is an independent prognostic factor in node-negative breast cancer

Personalized medicine requires the identification of unambiguous prognostic and predictive biomarkers to inform therapeutic decisions. Within this context, the management of lymph node-negative breast cancer is the subject of much debate with particular emphasis on the requirement for adjuvant chemotherapy. The identification of prognostic and predictive biomarkers in this group of patients is cru

Knee arthroscopies: who gets them, what does the radiologist report, and what does the surgeon find?

Background and purpose - Several randomized controlled trials have not shown any added benefit of arthroscopy over placebo surgery or physiotherapy in middle-aged patients with knee symptoms without trauma. We studied the characteristics of the knee arthroscopies performed in southern Sweden. Patients and methods - From the orthopedic surgical records from 2007-2009 in the Skåne region of Sweden (

Sub-adult Ravens Synchronize their Play : A Case of Emotional Contagion?

Emotional contagion – the alignment of emotions between individuals through behavioral synchronization – is proposed as a key, basic component of human social cognition and empathy. In the field of cognitive zoology, contagious behaviors have also received attention. Several such behaviors have been documented in various species. Nevertheless, emotional and behavioral contagion differ. Emotional c

Bee pollination improves crop quality, shelf life and commercial value.

Pollination improves the yield of most crop species and contributes to one-third of global crop production, but comprehensive benefits including crop quality are still unknown. Hence, pollination is underestimated by international policies, which is particularly alarming in times of agricultural intensification and diminishing pollination services. In this study, exclusion experiments with strawbe

Impact of Climate Conditions on Occupational Health and Related Economic Losses: A New Feature of Global and Urban Health in the Context of Climate Change.

One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this h
