Climate change has already triggered species distribution shifts in many parts of the world. Increasing impacts are expected for the future, yet few studies have aimed for a general understanding of the regional basis for species vulnerability. We projected late 21st century distributions for 1,350 European plants species under seven climate change scenarios. Application of the International Union

Background: Identifying individuals at high risk of developing Alzheimer's disease (AD) is important for future therapeutic strategies, and there is a clinical need for diagnostic biomarkers to identify incipient AD. Objective: The aim of the present study was to investigate if the AD-associated A beta peptide pattern recently found in cerebrospinal fluid (CSF) could discriminate between patients

The article’s findings show how in the Chinese reform-era of the 1980s and 90s, language control and strategic management of political discourse exercised by cadres in China's communist party propaganda apparatus helped forestall a development along Soviet lines ending with the sudden collapse of the socialist state. The findings indicate that the post-reform future—which in parts of China has, in

In this part of our studies, dealing with new approaches to the analysis of enzymatically hydrolyzed methyl cellulose, five different enzymes or enzyme preparations containing endoglucanases (from Bacillus agaradhaerens Cel 5A, Trichoderma reesei, Trichoderma Viride, and two obtained from Trichoderma longibrachiatum) were used to hydrolyze six different methyl celluloses (MCs). The main goal was t

A steady state agglomerate model for the MCFC cathode which takes into account the heterogeneous structure of this porous electrode is presented. The resulting model equations are solved by means of the finite element method. Calculations have been performed on two different test structures and include the influence of kinetics, porosity, outer surface area and distribution of electrolyte film. Co

We report a novel a lift-off method for nanoimprint lithography. This is a bi-layer method, using a polymethyl methacrylate (PMMA) on lift-off layer (LOL) resist scheme. For the imprint step, direct evidence for good pattern transfer down to 20 nm is shown. Oxygen plasma ashing is required to remove residual PMMA. A liquid solvent, MF 319, is used to transfer the pattern down to the silicon. The L

We assessed the effects of deep brain stimulation of the subthalamic nucleus (STN-DBS) or internal pallidum (GPi-DBS) on health-related quality of life (HrQoL) in patients with advanced Parkinson's disease participating in a previously reported multicenter trial. Sickness Impact Profile (SIP) questionnaires were available for analysis in a Subgroup of n = 20/20 patients with GPi-DBS and n = 45/49

The major histocompatibility complex (Mhc) of the ring-necked pheasant contains two polymorphic Mhc class II B genes. We show here, by screening of a cDNA library and RT-PCR from RNA, that both of these loci, Phco-DAB1 and Phco-DAB2, normally are transcribed in the spleen. They differ mainly in the 3' untranslated (UT) region, with the transcript lengths, not including the poly(A) tails, being 1,1

Cyclic dynamics of bird and mammal populations are commonly reported in northern latitudes throughout the world, and recent European observations on rodents and grouse suggest that cycle periods decline towards southern latitudes. To investigate latitudinal patterns of cyclic dynamics in North America, we assembled 27 long-term data sets collected between 1939 and 2001 for three grouse species. By

Experiments were performed in the temperature range of 294 - 1143 K in pure CO2 using high-resolution rotational coherent anti-Stokes Raman spectroscopy (CARS), in the dual-broadband approach. Experimental single-shot spectra were recorded with high spectral resolution using a single-mode Nd:YAG laser and a relay imaging lens system on the exit of a 1 m spectrometer. A theoretical rotational CARS

Pharyngeal constrictor paresis (PHCP) is sometimes found in videoradiography of the swallowing act in patients complaining of dysphagia. Ten patients with PHCP and 10 dysphagic, age- and sex-matched controls with normal videoradiography were neurologically evaluated and examined with magnetic resonance imaging (MRI) of the brain and brainstem in order to learn the pathogenetic process behind PHCP.

The Nef protein of human and simian immunodeficiency virus (HIV/SIV) is believed to interfere with T cell activation signals by forming a signaling complex at the plasma membrane. Composition and function of the complex are not fully understood. Here we report that Nef recruits the Polycomb Group (PcG) protein Eed, so far known as a nuclear factor and repressor of transcription, to the membrane of
