We report on the synthesis of non-tapered wurtzite (WZ) GaP nanowires by use of in-situ etching and the structural and optical characterization thereof. HCl was evaluated as an in-situ etchant in order to impede the onset of radial growth since the WZ crystal phase in GaP nanowires preferentially grows at relatively high growth temperatures around 600 degrees C, at which strong radial growth typic
Background Alpha-1-antitrypsin (A1AT) deficiency is the only recognised genetic risk factor for chronic obstructive pulmonary disease (COPD), a leading cause of morbidity and mortality worldwide. Since A1AT is the major inhibitor of neutrophil elastase (NE), this enzyme has become widely implicated in the pathogenesis of COPD in general; however, there is currently no specific biomarker for its pr

Objective: This study evaluated the tolerability and efficacy of inhaled AZD4818, a CCR1 antagonist, in patients with COPD. Methods: This double-blind, placebo-controlled study (NCT00629239) randomised patients with moderate to severe COPD to AZD4818 300 mu g or placebo twice daily via Turbuhaler (R) for 4 weeks. Safety, lung function, functional capacity and health status measures were measured.
Interannual variations in CO2 exchange across Amazonia, as deduced from atmospheric inversions, correlate with El Nino occurrence. They are thought to result from changes in net ecosystem exchange and fire incidence that are both related to drought intensity. Alterations to net ecosystem production (NEP) are caused by changes in gross primary production (GPP) and ecosystem respiration (R-eco). Her
ABSTRACT: BACKGROUND: Objective was to describe variations in how social insurance officers conceive the cooperation with the health care in their daily work with sick leave. METHODS: Fifteen social insurance officers (SIOs) working with administration of sickness benefits were interviewed. They were purposefully recruited to represent different parts of the social insurance office organization, d
Therapy-induced resistance remains a significant hurdle to achieve long-lasting responses and cures in cancer patients. We investigated the long-term consequences of genetically impaired angiogenesis by engineering multiple tumor models deprived of endoglin, a co-receptor for TGF-beta in endothelial cells actively engaged in angiogenesis. Tumors from endoglin-deficient mice adapted to the weakened
Direct photons are a powerful probe to study the property of quark–gluon plasma (QGP) in high energy heavy-ion collisions. In non-central collisions, the anisotropy of the collision region produces the different pressure gradients and particle density that results in different anisotropy of particle emission, depending on the production processes of photons. Therefore, an azimuthal anisotropy para
Three recent randomised trials have shown a lack of effect of EGDT for the treatment of severe sepsis and septic shock. Notably, control group care was excellent in all trials, including early recognition, early and aggressive fluid resuscitation and prompt administration of antibiotics, and was reflected in a lower than expected mortality.The discussion emphasizes the need for continued vigilanceThree recent randomised trials have shown a lack of effect of EGDT for the treatment of severe sepsis and septic shock.

Cerebellar Purkinje cells can learn to respond to a conditioned stimulus with an adaptively timed pause in firing. This response was usually ascribed to long-term depression of parallel fiber to Purkinje cell synapses but has recently been shown to be due to a previously unknown form of learning involving an intrinsic cellular timing mechanism. Here, we investigate how these responses are elicited
Patients with antineutrophil cytoplasm antibody-associated vasculitis (AAV) requiring dialysis at diagnosis are at risk for developing end-stage renal disease (ESRD) or dying. Shortterm results of a trial comparing plasma exchange (PLEX) to intravenous methylprednisolone (IV MeP) suggested PLEX improved renal recovery. Here we conducted long-term follow-up to see if this trend persisted. A total o
This paper addresses a problem related to control of web servers. Due to architectual issues, relevant measurements can only be taken over a limited part of the server system, which leaves the controller unaware of what happens in buffers proceeding the actual web-server (for instance, in the TCP/IP layers). In earlier presented work we modeled such a system and proved that the unmeasured bufferin
OBJECTIVE - The purpose of this study was to compare the incidence of vascular lower-limb amputation (LLA) in the diabetic and nondiabetic general population. RESEARCH DESIGN AND METHODS - A population-based cohort study was conducted in a representative Swedish region. All vascular LLAs (at or proximal to the transmetatarsal level) performed from 1997 through 2006 were consecutively registered an
Popular Abstract in Swedish De övergripand syftena med dessa studier var att undersöka vilka konsekvenser höftbesvär och höftledsartros har på hälsorelaterad livskvalité, fysisk förmåga och tilltro till egen förmåga. Höftledsartros är ofta förknippad med svår smärta och påverkar både fysiska funktioner och livskvalité. Förekomsten av höftbesvär, i en befolkningsgrupp i södra Sverige, var 32%, och The overall aims of this work were to investigate the consequences of hip disorders and hip osteoarthritis (OA) on health-related quality of life (HRQL) physical function and self-efficacy. The condition, hip OA, is often associated with significant pain and has a strong impact on physical function and quality of life. The prevalence of hip disorders were 32% and among the individuals reporting h
