Charge transfer between the Au(111) surface and adsorbed C-60: Resonant photoemission and new core-hole decay channels

The interaction of C-60 with the Au(111) surface has been investigated using synchrotron radiation-based electron spectroscopy. Resonant photoelectron spectroscopy and autoionization spectroscopy have been used to probe the coupling between the molecule and the substrate. Three distinct high energy spectator Auger features were observed that are only evident for a monolayer of C-60 chemisorbed to

Is increased joint loading detrimental to obese patients with knee osteoarthritis? A secondary data analysis from a randomized trial

Objective: To investigate whether increased knee joint loading due to improved ambulatory function and walking speed following weight loss achieved over 16 weeks accelerates symptomatic and structural disease progression over a subsequent 1 year weight maintenance period in an obese population with knee osteoarthritis (OA). Methods: Data from a prospective study of weight loss in obese patients wi

Reproducibility of ankle dorsiflexor muscle strength measurements in individuals with post-polio syndrome

The aim of this study was to assess the reproducibility of isokinetic and isometric ankle dorsiflexor strength measurements in individuals with post-polio syndrome (PPS). Thirty-one men and women (mean age 63 +/- 7.0 years) with verified PPS, participated in an intra-rater test-retest reproducibility study. Strength of the ankle dorsiflexor muscles in both lower limbs were measured twice, seven da

Influence of hydrogen content on impact toughness of Zr-2.5Nb pressure tube alloy

Influence of hydrogen content on the impact toughness of Zr-2.5% Nb alloy was examined by carrying out instrumented drop weight tests in the temperature range of 25-250 degrees C using curved Charpy specimens fabricated from unirradiated pressure tubes of Indian Pressurized Heavy Water Reactor (IPHWR). Hydrogen content of the samples was between 10 and 170 ppm by weight (wppm). Sharp ductile-to-br

Intercomparison of cloud condensation nuclei and hygroscopic fraction measurements: Coated soot particles investigated during the LACIS Experiment in November (LExNo)

Four cloud condensation nuclei (CCN) instruments were used to sample size-selected particles prepared at the Leipzig Aerosol Cloud Interaction Simulator facility. Included were two Wyoming static diffusion CCN instruments, the continuous flow instrument built by Droplet Measurement Technologies, and the continuous flow Leipzig instrument. The aerosols were composed of ammonium sulfate, levoglucosa

Tracing the 1271-1246 Ma Central Scandinavian Dolerite Group mafic magmatism in Fennoscandia: U-Pb baddeleyite and Hf isotope data on the Moslatt and Borgefjell dolerites

Between 1271 and 1246 Ma, dolerite dykes and sills of the Central Scandinavian Dolerite Group intruded into the Fennoscandian Shield during three distinct magmatic pulses. They are distributed around five large magmatic complexes extending from Sweden to western Finland and record large-scale intracratonic tensional stress. Coeval plutonism is observed in the westernmost terrane of the Sveconorweg

Cellobiose dehydrogenase modified electrodes: advances by materials science and biochemical engineering

The flavocytochrome cellobiose dehydrogenase (CDH) is a versatile biorecognition element capable of detecting carbohydrates as well as quinones and catecholamines. In addition, it can be used as an anode biocatalyst for enzymatic biofuel cells to power miniaturised sensor-transmitter systems. Various electrode materials and designs have been tested in the past decade to utilize and enhance the dir

Acceptor switching and axial rotation of the water dimer in matrices, observed by infrared spectroscopy.

Several isotopologues of the water dimer have been studied in different matrices (Ne, Ar, Kr, and p-H(2)) at very low temperatures. A fine structure, which is more or less matrix independent and very similar for different intramolecular fundamentals of the same isotopologic dimer, is present on the high wavenumber side of the main component. The bound OD (OH) stretches of the donor have temperatur

Stroke Prevention Worldwide - What Could Make It Work?

The global burden of stroke is of continual major importance for global health. The present report addresses some of the core principles that could make stroke prevention work. The prevention of stroke shares many common features with other non-communicable diseases (NCDs); stroke prevention should therefore be part of the joint actions on NCD led by the WHO and member states. Stroke prevention is

Retinol May Counteract the Negative Effect of Cadmium on Bone

Cadmium and high vitamin A intake are both proposed risk factors for low bone mineral density (BMD), but potential interactions have not been studied. Within the Women's Health in the Lund Area, a population-based study in southern Sweden, we measured retinol in serum among 606 women aged 54-64 y. Data on BMD were measured by DXA at the distal forearm. Parathyroid hormone (PTH), bone alkaline phos

The impact of inflammatory lipid mediators on colon cancer-initiating cells.

The role of inflammatory lipid-mediators in tumor progression is well recognized in colorectal cancer; however, if this includes promotion of cancer-initiating cells remains unclear. We show that the inflammatory lipid-mediators leukotriene D4 and prostaglandin E2 increased the Aldehyde dehydrogenase (ALDH(+) ) population, the colony formation capacity, and tumor growth in a xenograft model of col

Search for resonant diboson production in the WW/WZ -> lvjj decay channels with the ATLAS detector at root s=7 TeV

A search for resonant diboson production using a data sample corresponding to 4.7 fb(-1) of integrated luminosity collected by the ATLAS experiment at the Large Hadron Collider in pp collisions at root s = 7 TeV is presented. The search for a narrow resonance in the WW or WZ mass distribution is conducted in a final state with an electron or a muon, missing transverse momentum, and at least two je

An encephalomyelitis-specific locus on chromosome 16 in mouse controls disease development and expression of immune-regulatory genes.

A locus on mouse chromosome 16 was found to control experimental autoimmune encephalomyelitis (EAE) in studies using congenic mice. Genes within the congenic region control encephalomyelitis but not arthritis, indicating the presence of genes in this region involved in central nervous system (CNS) specific mechanisms. Flow cytometry analyses of expression of two candidate genes within the linked l

Relationship of plasma apolipoprotein M with proprotein convertase subtilisin-kexin type 9 levels in non-diabetic subjects

Purpose: Apolipoprotein M (apoM) retards atherosclerosis development in murine models, and may be regulated by pathways involved in LDL metabolism. Proprotein convertase subtilisin-kexin type 9 (PCSK9) plays a key role in LDL receptor processing. We determined the extent to which plasma apoM is related to PCSK9 levels in subjects with varying degrees of obesity. Methods: We sought correlations bet
