It has long been recognised that nitric oxide (NO) and nitrogen dioxide (NO2) can promote the oxidation of methane and other hydrocarbons under various fuel-lean and fuel-rich conditions and a range of temperatures and pressures conditions. However, despite the ease with which NO and NO2 interconvert under the oxidation conditions, the reactions responsible for initiating the oxidation process for

Duchenne muscular dystrophy (DMD) is a severe neuromuscular disorder, and one of the most frequently encountered, but one for which there is as yet no treatment. Laminin-111 protein therapy was recently shown to be a promising approach to prevent muscle disease in the mdx mouse model of DMD. The present study demonstrated that transgenic expression of laminin α1 chain in mdx animals, resulting in

The dynamics of ionization-induced electron injection in the high density (similar to 1.2 x 10(19)cm(-3)) regime of Laser Wakefield Acceleration (LWFA) was investigated by analyzing betatron X-ray emission inside dielectric capillary tubes. A comparative study of the electron and betatron X-ray properties was performed for both self-injection and ionization-induced injection. Direct experimental e

BackgroundMany malignancies, including multiple myeloma and its precursor, monoclonal gammopathy of unknown significant, are associated with an elevated risk of thromboembolism. There is limited information on the risk of thrombosis in patients with Waldenstrom macroglobulinemia (WM) and lymphoplasmacytic lymphoma (LPL). ObjectivesTo assess the risk of venous and arterial thrombosis in WM/LPL pati

OBJECTIVES: We examined whether the association between hormone therapy (HT) use and coronary heart disease (CHD) risk differed between women with and without vasomotor symptoms (VMS). STUDY DESIGN: We used data from a Dutch (EPOS) and Swedish (WHILA) population-based sample of 8865 women, aged 46-64 years, and free of CHD, stroke, venous thrombosis/pulmonary embolism or cancer at baseline. Data o

Study Design. Multicenter randomized controlled trial.Objective. To compare the efficacy and safety of balloon kyphoplasty (BKP) to non-surgical management (NSM) over 24 months in patients with painful vertebral compression fractures (VCF).Summary of Background Data. Recently, several large randomized controlled trials have been conducted and reported how vertebral augmentation compares with NSM f

BACKGROUND: The main objectives of this study were to clarify the contents of and attitudes to morning conferences for physicians at Swedish departments of anaesthesiology and intensive care medicine. METHODS: A prospective cross-sectional three-part study was carried out. Heads of departments responded to a national survey on the structure and content of morning conferences. A questionnaire on at

Class switch recombination (CSR) diversifies antibodies for productive immune responses while maintaining stability of the B-cell genome. Transcription at the immunoglobulin heavy chain (Igh) locus targets CSR-associated DNA damage and is promoted by the BRCT domain-containing PTIP (Pax transactivation domain-interacting protein). Although PTIP is a unique component of the mixed-lineage leukemia 3

Finger jointing of unseasoned Norway Spruce was studied with respect to tensile strength, adhesive penetration and durability. Finger joints were manufactured with 1) unseasoned wood and one component polyurethane (PUR) adhesive, 2) dried wood and PUR adhesive and 3) dried wood and phenol resorcinol formaldehyde (PRF) adhesive. Two levels of wood density were used. The tensile strength of the f

During the past 40 years brain tissue grafting techniques have been used both to study fundamental neurobiological questions and to treat neurological diseases. Motor symptoms of Parkinson's disease are largely due to degeneration of midbrain dopamine neurones. Because the nigrostriatal pathology is relatively focused anatomically, Parkinson's disease is considered the ideal candidate for brain re

Posterior corrective surgery using "all pedicle screw construct" carries risk of neurovascular complications. The study aims were to assess the screw placement in patients with adolescent idiopathic scoliosis using CT with low-radiation dose, and to evaluate the clinical outcome in patients with misplaced pedicle screws. CTs of 49 consecutive patients (873 screws, 79% thoracic) were retrospectivel

BackgroundPast research has identified aortic stenosis (AS) as a major risk factor for adverse outcomes in noncardiac surgery; however, more contemporary studies have questioned the grave prognosis. To further our understanding of this, the risks of a 30-day major adverse cardiovascular event (MACE) and all-cause mortality were investigated in a contemporary Danish cohort. HypothesisAS is not an i

Gene amplification is a common phenomenon in malignant neoplasms of all types. One mechanism behind increased gene copy number is the formation of ring chromosomes. Such structures are mitotically unstable and during tumor progression they accumulate material from many different parts of the genome. Hence, their content varies considerably between and within tumors. Partly due to this extensive va

An emerging number of diseases and therapeutic approaches with defined involvement of the complement system justify a need for specific markers reflecting activation of particular effector arms of the complement cascade. Measurement of such soluble markers in circulation is a challenge since the specificity of antibodies must be limited to activated complement fragments but not predominant and ubi

PURPOSE: To describe a heretofore unreported complication involving the Zenith Low Profile (LP) stent-graft. CASE REPORT: Two men, aged 75 and 67 years, respectively, underwent abdominal aortic aneurysm repair with a Zenith LP device. At 4 and 3 years, respectively, computed tomography angiography revealed separation of the proximal fixation stent from the stent-graft. In the first patient, ther

For development and evaluation of methods for predicting the effects of variations, benchmark datasets are needed. Some previously developed datasets are available for this purpose, but newer and larger benchmark sets for benign variants have largely been missing. VariSNP datasets are selected from dbSNP. These subsets were filtered against disease-related variants in the ClinVar, UniProtKB/Swiss-

Microparticles (MP) are small (100-1000 nm) membrane vesicles shed by cells as a response to activation, stress or apoptosis. Platelet-derived MP (PMP) has been shown to reflect the pathophysiological processes of a range of cardiovascular diseases and there is a potential clinical value in using PMPs as biomarkers, as well as a need to better understand the biology of these vesicles. The current

Engineers in large-scale software development have to manage large amounts of information, spread across many artifacts. Several researchers have proposed expressing retrieval of trace links among artifacts, i.e. trace recovery, as an Information Retrieval (IR) problem. The objective of this study is to produce a map of work on IR-based trace recovery, with a particular focus on previous evaluatio

We present new major and trace element data, as well as Sm–Nd isotope compositions for Archaean supracrustal rocks and a gabbro-anorthosite complex from the island of Storø in Godthåbsfjord, southern West Greenland. We also provide new U–Pb isotope data for zircon extracted from these rocks. The Storø rocks have experienced amphibolite facies metamorphism, and the entire sequence forms an east-dip
