Fully tunable, non-invasive thermal biasing of gated nanostructures suitable for low-temperature studies.

There is much recent interest in the thermoelectric (TE) characterization of single nanostructures at low temperatures, because such measurements yield information that is complementary to traditional conductance measurements, and because they may lead to novel paradigms for TE energy conversion. However, previously reported techniques for thermal biasing of nanostructures are difficult to use at

Report from the third international consensus meeting to harmonise core outcome measures for atopic eczema/dermatitis clinical trials (HOME)

This report provides a summary of the third meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in San Diego, CA, U.S.A., 6-7 April 2013 (HOME III). The meeting addressed the four domains that had previously been agreed should be measured in every eczema clinical trial: clinical signs, patient-reported symptoms, long-term control and quality of life. Formal presentations

A diabetes-predictive amino acid score and future cardiovascular disease.

AimsWe recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts dev

Lab-based Ultrafast Molecular Structure.

The proliferation of various laser-driven approaches to sub-picosecond hard X-ray and short-wavelength radiation generation in the past few decades has opened many avenues for the laboratory-based development of traditionally facility-based short wavelength ultrafast molecular structure science. Together with the introduction of microcalorimeter detection schemes, this opens the floodgates to wide

Identification of a novel A4GALT exon reveals the genetic basis of the P1/P2 histo-blood groups.

The A4GALT locus encodes a glycosyltransferase that synthesizes the terminal Galα1-4Gal of the P(k)(Gb3/CD77) glycosphingolipid, important in transfusion medicine, obstetrics and pathogen susceptibility. Critical nucleotide changes in A4GALT not only abolish P(k) formation but also another Galα1-4Gal-defined antigen, P1, which belongs to the only blood group system for which the responsible locus

Double Electron-Electron Resonance Probes Ca2+-Induced Conformational Changes and Dimerization of Recoverin

Recoverin a member of the neuronal calcium sensor (NCS) branch of the calmodulin superfamily, is expressed in retinal photoreceptor cells and serves as a calcium sensor in vision. Ca2+-induced conformational changes in recoverin cause extrusion of its covalently attached myristate (termed Ca2+-myristoyl switch) that promotes translocation of recoverin to disk membranes during phototransduction in

Suppression of glypican-1 autodegradation by NO-deprivation correlates with nuclear accumulation of amyloid beta in normal fibroblasts.

Heparan sulfate (HS)-containing, S-nitrosylated (SNO) glypican-1 (Gpc-1) releases anhydromannose-containing HS (anMan-HS) by SNO-catalyzed autodegradation in endosomes. Transport of anMan-HS to the nucleus requires processing of the amyloid precursor protein (APP) to amyloid beta peptides (Aβ). To further examine the relationship between APP and Gpc-1 processing in normal fibroblasts we have suppr

Ring-based versus disc-based separation of spatial scales: a case study on the impact of arable land proportions on invertebrates in freshwater streams

The impact of different land-use types on species is traditionally estimated by correlating landscape proportions recorded in buffer areas around focal points with species data observed at these sites. If a high proportion of a specific land-use type exists within a small radius, it will be accumulated in larger buffers and may confound the interpretation at larger scales. We sampled freshwater in

An investigation of the iterative reconstruction method iDose(4) on a Philips CT Brilliance 64 using a Catphan 600 phantom

The number of CT examinations giving a relatively high patient exposure is increasing. It is therefore important to optimize the imaging conditions at these investigations. Many steps have been taken to reduce the radiation doses in CT examinations. Currently much work is related to iterative image reconstruction methods as alternative to the filtered back projection method. The aim of this work w

Impaired Fibrous Repair: A Possible Contributor to Atherosclerotic Plaque Vulnerability in Patients With Type II Diabetes.

Diabetes mellitus (DM) type II is increasing rapidly worldwide. Patients with DM II have a greater atherosclerotic burden and higher risk of developing cardiovascular complications. Inflammation has been proposed as the main cause for the high risk of atherosclerotic disease in DM II. In this study, we compared markers of inflammation and fibrous repair in plaques from subjects with and without DM

Perfusion quantification by model-free arterial spin labeling using nonlinear stochastic regularization deconvolution.

Purpose: Quantification of cerebral blood flow can be accomplished by model-free arterial spin labeling using the quantitative STAR labeling of arterial regions (QUASAR) sequence. The required deconvolution is normally based on block-circulant singular value decomposition (cSVD)/oscillation SVD (oSVD), an algorithm associated with nonphysiological residue functions and potential effects of arteria

22q11.2 microduplication in two patients with bladder exstrophy and hearing impairment

Bladder exstrophy is a congenital malformation of the bladder and urethra. The genetic basis of this malformation is unknown however it is well known that chromosomal aberrations can lead to defects in organ development. A few bladder exstrophy patients have been described to carry chromosomal aberrations. Chromosomal rearrangements of 22q11.2 are implicated in several genomic disorders i.e. DiGeo

Transient Structures of PdO during CO Oxidation over Pd(100)

In situ high-energy surface X-ray diffraction was employed to determine the surface structure dynamics of a Pd(100) single crystal surface acting as a model catalyst to promote CO oxidation. The measurements were performed under semirealistic conditions, i.e., 100 mbar total gas pressure and 600 K sample temperature. The surface structure was studied in detail both in a steady gas flow and in a gr

Structural and spectroscopic characterization of tetranuclear iron complexes containing a (P2N2Ph)-N-R bridge

A pair of tetranuclear iron complexes consisting of two Fe-2(Cl(2)bdt)(CO)(5) subunits (Cl(2)bdt = 3,6-dicholorobenzene-1,2-dithiolate) bridged by different cyclic 1,5-diaza-3,7-diphosphacyclooctane (P2N2) ligands were prepared and structurally characterized. In the solid state, the P2N2 ligands adopt a boat conformation, which results in rather short distances between the two Fe-2(Cl(2)bdt)(CO)(5

Effects of a continuum of care intervention on frail older persons' life satisfaction: a randomized controlled study.

The aim of this study was to analyse effects of a comprehensive continuum of care (intervention group) on frail older persons' life satisfaction, as compared to those receiving usual care (control group). The intervention included geriatric assessment, case management, interprofessional collaboration, support for relatives and organising of care-planning meetings in older persons' own homes.
