The leaf-level emission factor of volatile isoprenoids: caveats, model algorithms, response shapes and scaling

In models of plant volatile isoprenoid emissions, the instantaneous compound emission rate typically scales with the plant's emission potential under specified environmental conditions, also called as the emission factor, ES. In the most widely employed plant isoprenoid emission models, the algorithms developed by Guenther and colleagues (1991, 1993), instantaneous variation of the steady-state em

Randomised controlled trial for emphysema with a selective agonist of the gamma-type retinoic acid receptor

Palovarotene is an oral gamma-selective retinoid agonist. In animal emphysema models, palovarotene reduced inflammation, promoted structural repair and functional improvement. REPAIR (Retinoid treatment of Emphysema in Patients on the alpha(1)-antitrypsin International Registry), was an investigator-initiated, double-blind, placebo-controlled randomised study to assess the safety and efficacy of 5

Vicariance and marine migration in continental island populations of a frog endemic to the Atlantic Coastal forest

The theory of island biogeography is most often studied in the context of oceanic islands where all island inhabitants are descendants from founding events involving migration from mainland source populations. Far fewer studies have considered predictions of island biogeography in the case of continental islands, where island formation typically splits continuous populations and thus vicariance al

Gas-phase dehydration of glycerol to acrolein over Al2O3-, SiO2- and TiO2-supported Nb- and W-oxide catalysts

Hypothetical monolayers loadings of niobium and tungsten oxide supported on alumina, silica and titania were investigated as catalysts for the dehydration of glycerol to produce acrolein. Besides activity measurements, to have information about the supported structures the catalysts were characterized by XRD, Raman spectroscopy, XPS, XANES and FTIR combined with adsorption of pyridine and CO2. Com

Anthropometric measures and bladder cancer risk: A prospective study in the EPIC cohort

Anthropometric measures have been related to risk of several cancers. For bladder cancer, however, evidence is sparse. Comparability of existing studies is hampered by use of different obesity-measures, inadequate control for smoking, and few female cases. This study examined associations between height, weight, waist and hip circumference, waist-hip ratio, waist-height ratio, body mass index (BMI

A beta 1-15/16 as a Potential Diagnostic Marker in Neurodegenerative Diseases

Cerebrospinal fluid (CSF) biomarkers for Alzheimer's disease (AD) reflect brain biochemistry. Using combined immunoprecipitation and mass spectrometry, we have shown that amyloid beta 1-15 (A beta 1-15) is produced by concerted beta- and alpha-secretase cleavage of amyloid precursor protein (APP) and that the relative levels of A beta 1-16 in AD compared to controls are increased. Furthermore, dru

Null Referential Subjects in Övdalian

In this article, Övdalian null subjects are introduced and analysed. A general background to Övdalian is provided, whereupon the possible null subjects (wįð ('we') and ið ('you')) are presented. Interestingly, these null subjects do not appear in the same syntactic positions; whereas null ið seems to be unrestricted, null wįð may only appear in positions immediately preceding the finite verb. It i

Endovascular Technique for Arterial Shunting to Prevent Intraoperative Ischemia.

The use of an intraoperative shunt is an established technique used to reduce the ischemic time after acute arterial obstruction or in the prevention of hypoperfusion due to complex open vascular or endovascular operative procedures. To date, described methods of temporary extremity blood perfusion have required open surgical techniques.

snoRNPs Regulate Telomerase Activity in Neuroblastoma and Are Associated with Poor Prognosis.

Amplification of the MYCN oncogene is strongly associated with poor prognosis in neuroblastoma (NB). In addition to MYCN amplification, many studies have focused on identifying patients with a poor prognosis based on gene expression profiling. The majority of prognostic signatures today are comprised of large gene lists limiting their clinical application. In addition, although of prognostic signi

Impact of gene dosage, loss of wild-type allele, and FLT3 ligand on Flt3-ITD-induced myeloproliferation

Acquisition of homozygous activating growth factor receptor mutations might accelerate cancer progression through a simple gene-dosage effect. Internal tandem duplications (ITDs) of FLT3 occur in approximately 25% cases of acute myeloid leukemia and induce ligand-independent constitutive signaling. Homozygous FLT3-ITDs confer an adverse prognosis and are frequently detected at relapse. Using a mou

Search for nonpointing photons in the diphoton and E-T(miss) final state in root s=7 TeV proton-proton collisions using the ATLAS detector

A search has been performed for photons originating in the decay of a neutral long-lived particle, exploiting the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction of photons, as well as the calorimeter's excellent time resolution. The search has been made in the diphoton plus missing transverse energy final state, using the full data sample

Importance of the Infusion Rate for the Plasma Expanding Effect of 5% Albumin, 6% HES 130/0.4, 4% Gelatin, and 0.9% NaCl in the Septic Rat.

OBJECTIVES:: To compare the plasma volume (PV) expanding effect of a fast infusion rate with that of a slow infusion rate of a fixed volume of 5% albumin, of the synthetic colloids, 6% hydroxyethyl starch 130/0.4 and 4% gelatin, and of 0.9% NaCl in a rat sepsis model and to compare the plasma-expanding effect among these fluids. DESIGN:: Prospective, randomized animal study. SETTING:: University h

An Evolutionary Genomic Approach to Identify Genes Involved in Human Birth Timing

Coordination of fetal maturation with birth timing is essential for mammalian reproduction. In humans, preterm birth is a disorder of profound global health significance. The signals initiating parturition in humans have remained elusive, due to divergence in physiological mechanisms between humans and model organisms typically studied. Because of relatively large human head size and narrow birth

Increased plasma level of soluble urokinase plasminogen activator receptor is associated with incidence of heart failure but not atrial fibrillation.

Soluble urokinase plasminogen activator receptor (suPAR) in plasma is a novel inflammatory marker thought to be released from the cell surface of neutrophils, T cells, and macrophages. Other inflammatory markers, mainly acute phase proteins produced in the liver, have been associated with the incidence of heart failure (HF) and atrial fibrillation (AF). We investigated the association between suPA

Nonpharmacologic Interventions Need Outcomes for Evaluating Complex Interventions in Rheumatic Diseases

Introduction. Nonpharmacologic interventions are themselves complex and are often combined with drugs and other interventions in the treatment of rheumatic diseases. Therefore, overall strategies for treatment are complex interventions. These should be evaluated regarding their processes and outcomes. Methods. The CARE network, an international organization of health professionals (physicians and

Modern treatment of acute mesenteric ischaemia.

Diagnosis of acute mesenteric ischaemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischaemia may be treated with urgent intestinal revascularization.

Stability Analysis of Transportation Networks with Multiscale Driver Decisions

Stability of Wardrop equilibria is analyzed for dynamical transportation networks in which the drivers' route choices are influenced by information at multiple temporal and spatial scales. The considered model involves a continuum of nonatomic indistinguishable drivers commuting between a common origin-destination pair in an acyclic transportation network. The drivers' route choices are affected b
