BACKGROUND: In the last decades, several efforts have been done to clarify the role of BRCA mutational status in women with advanced ovarian cancer demonstrating its role in cancer development, as well as the prognostic significance of BRCA genotype. OBJCTIVE: Our aim is to evaluate the correlation between BRCA mutational status and disease presentation in a large series of advanced high-grade serous ovarian cancer patients. STUDY DESIGN: this is a retrospective multicenter study including a consecutive series of newly diagnosed high-grade serous ovarian cancer patients with FIGO Stage IIIC-IV disease, at least 18 months of follow-up time, tested for BRCA 1/2 germline mutation status...

The goal of this work is to understand adsorption-induced deformation of hierarchically structured porous silica exhibiting well-defined cylindrical mesopores. For this purpose, we performed an in situ dilatometry measurement on a calcined and sintered monolithic silica sample during the adsorption of N2 at 77 K. To analyze the experimental data, we extended the adsorption stress model to account for the anisotropy of cylindrical mesopores, i.e., we explicitly derived the adsorption stress tensor components in the axial and radial direction of the pore...

Previous studies suggest that, while both medical students and professional anatomists recognise the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy (Morgan et al., 2014, 2016). To further investigate these issue, we provided second year medical students at Cardiff University (n=293) and at the University of Paris Descartes, Sorbonne Paris Cité (n= 142) and professional anatomists in Europe (n= 208) with a questionnaire inviting them to address the possibility that gender factors within anatomical imagery (both historical and contemporary) hinder the dispassionate representation of anatomy...

BACKGROUND AND PURPOSE: To evaluate hyperacute management of pediatric arterial ischemic stroke, setting up dedicated management pathways is the first recommended step to prove the feasibility and safety of such treatments. A regional pediatric stroke alert protocol including 2 centers in the Paris-Ile-de-France area, France, was established. METHODS: Consecutive pediatric patients (28 days-18 years) with confirmed arterial ischemic stroke who had acute recanalization treatment (intravenous r-tPA [recombinant tissue-type plasminogen activator], endovascular procedure, or both) according to the regional pediatric stroke alert were retrospectively reviewed during a 40-month period...

Objectives Outbreaks of Kingella kingae invasive infections have recently been reported in day-care centers. Pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) revealed that although the invasive strains had a widespread dissemination in the day-care population, less virulent strains were also found to be circulating in the facility. However, these typing tools are costly, time-consuming and labor-intensive, and provide delayed results. A study was conducted to assess the performance of a rapid and cost-effective genotyping tool targeting the DNA uptake sequence (DUS) in the investigation of outbreaks of K...

The prevalence of non-autonomous class II transposable elements (TEs) in plant genomes may serve as a tool for relatively rapid and low-cost development of gene-associated molecular markers. Miniature inverted-repeat transposable element (MITE) copies inserted within introns can be exploited as potential intron length polymorphism (ILP) markers. ILPs can be detected by PCR with primers anchored in exon sequences flanking the target introns. Here, we designed primers for 209 DcSto (Daucus carota Stowaway-like) MITE insertion sites within introns along the carrot genome and validated them as candidate ILP markers in order to develop a set of markers for genotyping the carrot...

The concept of hypofractionation is gaining momentum in radiation oncology centres, enabled by recent advances in radiotherapy apparatus. The gain of efficacy of this innovative treatment must be defined. We present a computer model based on translational murine data for in silico testing and optimization of various radiotherapy protocols with respect to tumour resistance and the microenvironment heterogeneity. This model combines automata approaches with image processing algorithms to simulate the cellular response of tumours exposed to ionizing radiation, modelling the alteration of oxygen permeabilization in blood vessels against repeated doses, and introducing mitotic catastrophe (as opposed to arbitrary delayed cell-death) as a means of modelling radiation-induced cell death...

Characteristics of late maturity in fruit are good agronomic traits for extending the harvest period and marketing time. However, underlying molecular basis of the late-maturing mechanism in fruit is largely unknown. In this study, RNA sequencing (RNA-Seq) technology was used to identify differentially expressed genes (DEGs) related to late-maturing characteristics from a late-maturing mutant 'Huawan Wuzishatangju' (HWWZSTJ) (Citrus reticulata Blanco) and its original line 'Wuzishatangju' (WZSTJ). A total of approximately 17...

The ACR Incidental Findings Committee (IFC) presents recommendations for managing pancreatic cysts that are incidentally detected on CT or MRI. These recommendations represent an update from the pancreatic component of the JACR 2010 white paper on managing incidental findings in the adrenal glands, kidneys, liver, and pancreas. The Pancreas Subcommittee-which included abdominal radiologists, a gastroenterologist, and a pancreatic surgeon-developed this algorithm. The recommendations draw from published evidence and expert opinion, and were finalized by informal iterative consensus...

Transfusion-dependent hereditary anemias such as β-thalassemia (β-thal), predispose patients to iron overload and its numerous clinical sequelae. Accurate assessment of overall iron status and prompt initiation of chelation therapy to prevent irreversible end-organ damage can be achieved using magnetic resonance imaging (MRI) to measure liver iron concentration (LIC) as a surrogate marker of total body iron; however, its access may be associated with long wait times and delay in treatment. We report an observational cohort study at a single tertiary care center assessing the theoretical role of transient elastography (TE), which measures liver stiffness, in estimating LIC compared to other established diagnostic measures...

Antibacterial polyolefins surfaces, combining biocidal and antiadhesive properties, were elaborated by a covalent grafting of antimicrobial peptides (AMPs), able to kill adherent bacteria, on a pre-immobilized hyaluronic acid (HA) layer, able to repel the micro-organisms. Different HA activation rate for its immobilization, were used to change HA layer morphology and number of residual free carboxylic acid functions for AMPs grafting. Based on adhesion tests on Staphylococcus epidermidis and microscopy fluorescent observations, the presence of the two combined properties was shown to be depended on the HA activation rate...

An original concept for the property tuning of semiconductors is demonstrated by the synthesis of a p-type zinc oxide (ZnO)-like metal-organic framework (MOF), (ZnC2O3H2)n, which can be regarded as a possible alternative for ZnO, a natural n-type semiconductor. When small oxygen-rich organic linkers are introduced to the Zn-O system, oxygen vacancies and a deep valence-band maximum, the two obstacles for generating p-type behavior in ZnO, are restrained and raised, respectively. Further studies of this material on the doping and photoluminescence behaviors confirm its resemblance to metal oxides (MOs)...

This study aimed to distinguish the rhizomes of Paris polyphylla var. yunnanensis (Franch) Hand Mazz (PPY) and Paris veitnamensis (Takht.) H. Li (PV) using metabolomics-based ultra high-performance liquid chromatography coupled with quadrupole time-of-fligh mass spectrometry (UHPLC/Q-TOF MS). First, the UHPLC/Q-TOF MS approach was optimized for metabolite profiling. Then, the MS data were processed using UNIFI™ combined with an in-house library to automatically characterize the metabolites. Based on the exact mass information, the fragmentation characteristics, and the retention time of compounds, and the fragmentation mechanism and retention behavior of steroidal glycosides in the references, the structures identified by UNIFI were further verified...

INTRODUCTION: Microsurgical techniques are essential in plastic surgery; however, inconsistent training practices, acquiring these skills can be difficult. To address this, we designed a standardised laboratory-based microsurgical training programme, which allows trainees to develop their dexterity, visuospatial ability, operative flow and judgement as separate components. METHOD: Thirty trainees completed an initial microsurgical anastomosis on a chicken femoral artery, assessed using the structured assessment of microsurgical skills (SAMS) method...

After the november 19th 2015 Paris terrorist attacks, there was a clear need to update the Medical Intervention Plans (MIP) for Mass Casualty Events (MCE) in the Brussels Capital Region (BCR), because they only offered a response to single-site MCE in a peace-time context. We compared the organisation and the resources of the BCR and cities like Paris and Lille, we discussed with our french colleagues and formed a Multisite Attack Task-force that produced a specific multisite MIP, which had to be put to use only a few days after its creation...
