Effect of terbutaline on hyperpnoea-induced bronchoconstriction and urinary club cell protein 16 in athletes

Repeated injury of the airway epithelium caused by hyperpnoea of poorly conditioned air has been proposed as a key factor in the pathogenesis of exercise-induced bronchoconstriction (EIB) in athletes. In animals, the short-acting beta(2)-agonist terbutaline has been shown to reduce dry airflow-induced bronchoconstriction and the associated shedding of airway epithelial cells. Our aim was to test t

Apleurotropis Girault (Hymenoptera: Eulophidae) new to tropical America, including six new species and biological records

The genus Apleurotropis Girault is here reported for the first time from tropical America. The genus is diagnosed and compared to Achrysocharoides Girault with which it shares important characters. Changes are suggested in two existing keys to Neotropical/Nearctic genera of Eulophidae to include Apleurotropis. Included in Apleurotropis are also six newly described species: A. albicaulis, A. albisc

Country of birth, socioeconomic factors and risk factor control in patients with type 2 diabetes: A Swedish study from 25 primary health care centers.

BACKGROUND: Few large-scale studies have examined the association between sociodemographic factors and the probability of reaching the recommended levels of HbA1c and blood lipids in patients with type 2 diabetes. The aim was to investigate whether sociodemographic characteristics of type 2 diabetes patients affected the odds that they would reach recommended levels of blood lipids and HbA1c. METH

Strategy-proof social choice on multiple and multi-dimensional single-peaked domains

We generalize the traditional concept of single-peaked preference domains in two ways. First, we introduce the concept of a multiple single-peaked domain, where the set of alternatives is equipped with several underlying orderings with respect to which a preference can be single-peaked, and we argue that these domains are appropriate to represent preferences over political parties. Second, we defi

The MM/PBSA and MM/GBSA methods to estimate ligand-binding affinities

Introduction: The molecular mechanics energies combined with the Poisson-Boltzmann or generalized Born and surface area continuum solvation (MM/PBSA and MM/GBSA) methods are popular approaches to estimate the free energy of the binding of small ligands to biological macromolecules. They are typically based on molecular dynamics simulations of the receptor-ligand complex and are therefore intermedi

Low atrial fibrillatory rate is associated with spontaneous conversion of recent-onset atrial fibrillation.

AIMS: Atrial fibrillatory rate (AFR) is considered a non-invasive index of atrial remodelling. Low AFR has been associated with favourable outcome of interventions in patients with persistent atrial fibrillation (AF). However, AFR has never been studied in unselected patients with short duration of AF, prone to regain sinus rhythm (SR) spontaneously. The aim of the study was to assess if AFR can p

Development of Frequency of Stools over Time in Children with Hirschsprung Disease Posttransanal Endorectal One-Stage Pull-through.

Background The transanal endorectal one-stage pull-through (TERPT) procedure in children with Hirschsprung disease (HD) is frequently used worldwide. To give the children's families realistic expectations and to plan the medical care for the period after TERPT, the outcome is of great importance. Aim The aim of this article is to collect information on the number of stools passed daily after one-s

Induced magnetism of carbon atoms at the graphene/Ni(111) interface

We report an element-specific investigation of electronic and magnetic properties of the graphene/Ni(111) system. Using x-ray magnetic circular dichroism, the occurrence of an induced magnetism of the carbon atoms in the graphene layer is observed. We attribute this magnetic moment to the strong hybridization between C pi and Ni 3d valence band states. The net magnetic moment of carbon in the grap

Immunomodulatory nanoparticles as adjuvants and allergen-delivery system to human dendritic cells: Implications for specific immunotherapy.

Novel adjuvants and antigen-delivery systems with immunomodulatory properties that shift the allergenic Th2 response towards a Th1 or regulatory T cell response are desired for allergen-specific immunotherapy. This study demonstrates that 200-nm sized biodegradable poly(gamma-glutamic acid) (gamma-PGA) nanoparticles (NPs) are activators of human monocyte-derived dendritic cells (MoDCs). gamma-PGA

Immunologic findings in young children with early onset of acute otitis media.

Abstract Conclusion: No significant differences in the number of immune aberrations were seen between children with or without severe recurrent acute otitis media (rAOM); however, subnormal values of immunological markers were found more often than expected, and 4 of the 60 children had treatment-requiring immune deficiencies.

Flap Dynamics in Aspartic Proteases : A Computational Perspective

Recent advances in biochemistry and drug design have placed proteases as one of the critical target groups for developing novel small-molecule inhibitors. Among all proteases, aspartic proteases have gained significant attention due to their role in HIV/AIDS, malaria, Alzheimer's disease, etc. The binding cleft is covered by one or two β-hairpins (flaps) which need to be opened before a ligand can

Ultrafast photoinduced dynamics in quantum dot-based systems for light harvesting

Colloidal semiconductor nanocrystals, referred to as quantum dots, offer simple low-temperature solution-based methods for constructing optoelectronic devices such as light emitting diodes and solar cells. We review recent progress in the understanding of photoinduced processes in key components of a certain type of quantum dot solar cells where the dots sensitize a suitable metal oxide, such as Z

Bumble bees show trait-dependent vulnerability to landscape simplification

Agricultural intensification has resulted in large-scale loss of bee pollinators, but while some species have been negatively affected others seem to endure changed conditions. It has been suggested that certain morphological, ecological and life-history traits make some species more vulnerable to landscape changes. Information on which traits make species vulnerable and why may aid conservation o

Search for excited leptons in proton-proton collisions at root s=7 TeV with the ATLAS detector

The ATLAS detector is used to search for excited leptons in the electromagnetic radiative decay channel l* -> l gamma. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 2.05 fb(-1). No evidence for excited leptons is found, and limits are set on the compositeness scale Lambda as a function of the excited le
