Target definition in radiotherapy of prostate cancer using magnetic resonance imaging only workflow

In magnetic resonance (MR) only radiotherapy, the target delineation needs to be performed without computed tomography (CT). We investigated in thirteenpatients with prostate cancer, how the clinical target volume (CTV) was affected, when the target delineation procedure was changed from using both CT and MRimages to using MR images only. The mean volume of the CTVCT/MR was 61.0 cm3 as compared to

Promoting eco-innovation in academic eco-systems

University incubators are an opportunity to promote the dissemination of research, change teaching practices and contribute to territorial economic development. In this article we present a structural and dynamic analysis of such an innovation system of a Swedish eco-innovation system by proposing elements for analysing the success of such innovation systems.

Prognostication after cardiac arrest : Results of an international, multi-professional survey

Aim: We explored preferences for prognostic test performance characteristics and error tolerance in decisions regarding withdrawal or continuation of life-sustaining therapy (LST) after cardiac arrest in a diverse cohort of medical providers. Methodology: We distributed a survey through professional societies and research networks. We asked demographic characteristics, preferences for prognostic t

Observer Backstepping for a Class of Nonminimum-Phase Systems

In this paper the stabilization of nonlinear nonminimum-phase systems is considered. In particular the observer backstepping design of Krstic et al. [12] is extended to stabilization of a class of nonlinear syst ems in output-feedback form with linear unstable zero-dynamics.

Nonlinear Observers and Output Feedback Control with Application to Dynamically Positioned Ships

The decomposition of nonlinear output feedback control into an observer and a state feedback control is an open problem. A solution for dynamic positioning of ships has been proposed by Fossen and Grøvlen (1998) and Grøvlen and Fossen (1996), where an observer-based backstepping method is used.The suggested observer design in Fossen and Grøvlen (1998) and Grøvlen and Fossen (1996) does not cover u

p120ctn-Mediated Organ Patterning Precedes and Determines Pancreatic Progenitor Fate

The mechanism of how organ shape emerges and specifies cell fate is not understood. Pancreatic duct and endocrine lineages arise in a spatially distinct domain from the acinar lineage. Whether these lineages are pre-determined or settle once these niches have been established remains unknown. Here, we reconcile these two apparently opposing models, demonstrating that pancreatic progenitors re-loca

Experimental and theoretical 2p core-level spectra of size-selected gas-phase aluminum and silicon cluster cations : Chemical shifts, geometric structure, and coordination-dependent screening

We present 2p core-level spectra of size-selected aluminum and silicon cluster cations from soft X-ray photoionization efficiency curves and density functional theory. The experimental and theoretical results are in very good quantitative agreement and allow for geometric structure determination. New ground state geometries for Al 12 + , Si 15 + , Si 16 + , and Si 19 + are proposed on thi

Alternative splicing and ACMG-AMP-2015-based classification of PALB2 genetic variants : An ENIGMA report

Background: PALB2 monoallelic loss-of-function germ-line variants confer a breast cancer risk comparable to the average BRCA2 pathogenic variant. Recommendations for risk reduction strategies in carriers are similar. Elaborating robust criteria to identify loss-of-function variants in PALB2 - without incurring overprediction - is thus of paramount clinical relevance. Towards this aim, we have perf

Atrial fibrillation in cryptogenic stroke and transient ischaemic attack – The Nordic Atrial Fibrillation and Stroke (NOR-FIB) Study : Rationale and design

Purpose: Paroxysmal atrial fibrillation is often suspected as a probable cause of cryptogenic stroke. Continuous long-term ECG monitoring using insertable cardiac monitors is a clinically effective technique to screen for atrial fibrillation and superior to conventional follow-up in cryptogenic stroke. However, more studies are needed to identify factors which can help selecting patients with the

Meta-Analysis of Genomewide Association Studies Reveals Genetic Variants for Hip Bone Geometry

Hip geometry is an important predictor of fracture. We performed a meta-analysis of GWAS studies in adults to identify genetic variants that are associated with proximal femur geometry phenotypes. We analyzed four phenotypes: (i) femoral neck length; (ii) neck-shaft angle; (iii) femoral neck width, and (iv) femoral neck section modulus, estimated from DXA scans using algorithms of hip structure a

Regulatory changes in pterin and carotenoid genes underlie balanced color polymorphisms in the wall lizard

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors. These conspicuous colors serve a diversity of signaling functions, but their molecular basis remains unresolved. Here, we show that the genomes of sympatric color morphs of the European common wall lizard (Podarcis muralis), which differ in orange and yellow pigmentation and in their ecology and behavior, are vi

Associations between intraoperative factors and surgeons’ self-assessed operative satisfaction

Background: Little is known concerning what may influence surgeon satisfaction with a surgical procedure and its associations with intraoperative factors. The objective was to explore the relationships between surgeons’ self-assessed satisfaction with performed radical prostatectomies and intraoperative factors such as technical difficulties and intraoperative complications as reported by the surg
