Common Genetic Variants and Modification of Penetrance of BRCA2-Associated Breast Cancer

The considerable uncertainty regarding cancer risks associated with inherited mutations of BRCA2 is due to unknown factors. To investigate whether common genetic variants modify penetrance for BRCA2 mutation carriers, we undertook a two-staged genome-wide association study in BRCA2 mutation carriers. In stage 1 using the Affymetrix 6.0 platform, 592,163 filtered SNPs genotyped were available on 89

Pressure and Phase Equilibria in Interacting Active Brownian Spheres

We derive a microscopic expression for the mechanical pressure P in a system of spherical active Brownian particles at density ρ. Our exact result relates P, defined as the force per unit area on a bounding wall, to bulk correlation functions evaluated far away from the wall. It shows that (i) P(ρ) is a state function, independent of the particle-wall interaction; (ii) interactions contribute two

Oncogenic activation of FOXR1 by 11q23 intrachromosomal deletion-fusions in neuroblastoma

Neuroblastoma tumors frequently show loss of heterozygosity of chromosome 11q with a shortest region of overlap in the 11q23 region. These deletions are thought to cause inactivation of tumor suppressor genes leading to haploinsufficiency. Alternatively, micro-deletions could lead to gene fusion products that are tumor driving. To identify such events we analyzed a series of neuroblastomas by comp

The effects of aeration on growth and toxicity of Prymnesium parvum grown with and without algal prey

We investigated the effects of aeration on growth and toxicity of the haptophyte Prymnesium parvum in the presence and absence of the algal prey Rhodomonas sauna. Batch monocultures of P-limited P. parvum and N and P sufficient R. sauna and mixed cultures of the two microalgae were grown with no, low (20) and high (100) ml min(-1) aeration for 18 days. Cell growth of P. parvum and R. salina and ce

Post-Genomic Update on a Classical Candidate Gene for Coronary Artery Disease: ESR1

Background-After age, sex is the most important risk factor for coronary artery disease (CAD). The mechanism through which women are protected from CAD is still largely unknown, but the observed sex difference suggests the involvement of the reproductive steroid hormone signaling system. Genetic association studies of the gene-encoding Estrogen Receptor alpha (ESR1) have shown conflicting results,

Nocturnal insects use optic flow for flight control.

To avoid collisions when navigating through cluttered environments, flying insects must control their flight so that their sensory systems have time to detect obstacles and avoid them. To do this, day-active insects rely primarily on the pattern of apparent motion generated on the retina during flight (optic flow). However, many flying insects are active at night, when obtaining reliable visual in

Iterative merging heuristics for correlation clustering

A straightforward natural iterative heuristic for correlation clustering in the general setting is to start from singleton clusters and whenever merging two clusters improves the current quality score merge them into a single cluster. We analyse the approximation and complexity aspects of this heuristic and its three simple deterministic or random refinements.

Dissociation of severity of stroke and aphasia recovery early after intravenous recombinant tissue plasminogen activator thrombolysis.

Clinical observation suggested to us that aphasia recovers relatively better than other deficits early after intravenous recombinant tissue plasminogen activator (IV-rtPA) treatment in stroke patients with minor deficits, while the reverse seemed the case in those with severe deficits. Retrospective analysis of acute ischemic stroke patients with aphasia admitted within 3hours from symptom onset a

CONVERSION FACTORS FOR ESTIMATION OF EFFECTIVE DOSE IN PAEDIATRIC CHEST TOMOSYNTHESIS.

For chest tomosynthesis in adults, a conversion factor of 0.26 mSv/Gy cm(2) has been reported for calculating the effective dose from the registered dose-area-product. The aim of this study was to determine conversion factors for chest tomosynthesis in children. Using the Monte Carlo-based computer software PCXMC 2.0, simulations were performed on modified phantoms for males and females aged 8-19

Unravelling causes of defects in construction

The purpose of this study is to identify the primary root causes of defects in terms of why they persist in construction, despite the increasing implementation of quality systems. Defects in construction continue to be a source of concern in the construction industry. There have been studies that have tried to identify causes of defects. Although concepts are usually related to organisational fact

Optimizing network load balancing: an hybridization approach of metaheuristics with column generation

Given a capacitated telecommunications network with single path routing and an estimated traffic demand matrix, we aim to determine the routing path of each traffic commodity such that the whole set of paths provide an optimal network load balancing. In a recent paper, we have proposed a column generation based heuristic where, in the first step, we use column generation to solve a linear programm

European Resuscitation Council and European Society of Intensive Care Medicine 2015 guidelines for post-resuscitation care.

The European Resuscitation Council and the European Society of Intensive Care Medicine have collaborated to produce these post-resuscitation care guidelines, which are based on the 2015 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. Recent changes in post-resuscitation care include: (a) greater emphasis on the need for urgent coronary catheterisati

miR-145 suppress the androgen receptor in prostate cancer cells and correlates to prostate cancer prognosis.

Androgen signalling through the androgen receptor (AR) is essential for prostate cancer initiation, progression and transformation to the lethal castration-resistant state. The aim of this study was to characterize the mechanisms by which miR-145 deregulation contribute to prostate cancer progression. The miR-145 levels, measured by quantitative reverse transcription-polymerase chain reaction, wer

Chromosome 19 Annotations with Disease Speciation - A First Report from the Global Research Consortium

A first research development progress report of the Chromosome 19 Consortium with members from Sweden, Norway, Spain, USA, China and India, a part of the Chromosome-Centric Human Proteome Project (C-HPP) global initiative is presented (http://www.c-hpp.org). From the chromosome 19 peptide-targeted library constituting 6159 peptides, a pilot study was conducted using a sub-set with 125 isotope-labe

The +1444C>T polymorphism in the CRP gene: a study on personality traits and suicidal behaviour.

OBJECTIVES: Numerous studies have shown associations between an on-going depression and elevated serum levels of the acute-phase reactant C-reactive protein (CRP). Also, in suicidal behaviour, a proinflammatory state has been suggested to be of importance for the pathophysiology. There is a genetic susceptibility to suicidal behaviour, but studies with respect to genes related to inflammation are

Marriage in the canons of the council in Trullo

This study presents the historical development of marriage as a legal object in Eastern Orthodox canon law. The argument of the article is that the need of the ecclesial policy to adapt to a new situation following the Islamic conquests of the seventh century led to the development an ecclesiastical common law independent of Byzantine-Roman civil law in order to survive under Muslim rule. The sour

Urinary BPA measurements in children and mothers from six European member states: Overall results and determinants of exposure.

For the first time in Europe, both European-wide and country-specific levels of urinary Bisphenol A (BPA) were obtained through a harmonized protocol for participant recruitment, sampling and quality controlled biomarker analysis in the frame of the twin projects COPHES and DEMOCOPHES. 674 child-mother pairs were recruited through schools or population registers from six European member states (Be

Towards the modelling of ageing and atherosclerosis effects in ApoE(-/-) mice aortic tissue.

The goal of this work consists in a quantitative analysis and constitutive modelling of ageing processes associated to plaque formation in mice arteries. Reliable information on the characteristic evolution of pressure-stretch curves due to the ageing effects is extracted from previous inflation test experiments. Furthermore, characteristic age-dependent material parameters are identified on the b
