J Biomed Inform 2019 Apr 19:103182. Epub 2019 Apr 19.

Department of Bio and Brain Engineering, KAIST, Daejeon, Republic of Korea. Electronic address:

There have been many attempts to identify relationships among concepts corresponding to terms from biomedical information ontologies such as the Unified Medical Language System (UMLS). In particular, vector representation of such concepts using information from UMLS definition texts is widely used to measure the relatedness between two biological concepts. However, conventional relatedness measures have a limited range of applicable word coverage, which limits the performance of these models. Read More

The European cross-border health data exchange roadmap: case study in the Italian setting.

J Biomed Inform 2019 Apr 19:103183. Epub 2019 Apr 19.

Insitute of Cristallography - CNR, Rome, Italy.

Health data exchange is a major challenge due to the sensitive information and the privacy issues entailed. Considering the European context, in which health data must be exchanged between different European Union (EU) Member States, each having a different national regulatory framework as well as different national healthcare system structures/organizations, the challenge is even greater. Europe has tried to address this challenge by launching in 2008, the epSOS ("Smart Open Services for European Patients") project, which was a European large-scale pilot on cross-border sharing of specific health data and services.

Computational models for the assessment of manufactured nanomaterials: Development of model reporting standards and mapping of the model landscape.

Comput Toxicol 2019 Feb;9:143-151

European Commission, Joint Research Centre (JRC), Ispra, Italy.

Different types of computational models have been developed for predicting the biokinetics, environmental fate, exposure levels and toxicological effects of chemicals and manufactured nanomaterials (MNs). However, these models are not described in a consistent manner in the scientific literature, which is one of the barriers to their broader use and acceptance, especially for regulatory purposes. Quantitative structure-activity relationships (QSARs) are models based on the assumption that the activity of a substance is related to its chemical structure. Read More

Adult Learning Theories in Context: A Quick Guide for Healthcare Professional Educators.

J Med Educ Curric Dev 2019 Jan-Dec;6:2382120519840332. Epub 2019 Apr 10.

Department of Pharmacy & Pharmacology, University of Bath, Bath, UK.

Background: Adult learning theories play a pivotal role in the design and implementation of education programs, including healthcare professional programs. There is a variation in the use of theories in healthcare professional education programs and this is may be in part due to a lack of understanding of the range of learning theories available and paucity of specific, in-context examples, to help educators in considering alternative theories relevant to their teaching setting. This article seeks to synthesize key learning theories applicable in the learning and teaching of healthcare professionals and to provide examples of their use in context. Read More

Hypermentalizing as a marker of borderline personality disorder in Italian adolescents: a cross-cultural replication of Sharp and colleagues' (2011) findings.

Borderline Personal Disord Emot Dysregul 2019 10;6. Epub 2019 Apr 10.

1Faculty of Psychology, Vita-Salute San Raffaele University, via Stamira d'Ancona 20, 20127 Milan, Italy.

Background: Extant literature indicates that Borderline Personality Disorder (BPD) may be reliably assessed in adolescence. Sharp and colleagues' (2011) suggested that mentalization could be an important early target for intervention in BPD adolescents and showed that hypermentalizing may represent an important marker to distinguish emerging BPD from adolescent turmoil. We aimed at testing if both dimensionally-assessed and categorically-diagnosed BPD was selectively associated with hypermentalizing errors on the Movie for the Assessment of Social Cognition (MASC) task in Italian adolescent inpatients and community adolescents.

Geometry of the Kahan discretizations of planar quadratic Hamiltonian systems.

Proc Math Phys Eng Sci 2019 Mar 13;475(2223):20180761. Epub 2019 Mar 13.

Institut für Mathematik, MA 7-1, Technische Universität Berlin, Straße des 17. Juni 136, 10623 Berlin, Germany.

Kahan discretization is applicable to any quadratic vector field and produces a birational map which approximates the shift along the phase flow. For a planar quadratic canonical Hamiltonian vector field, this map is known to be integrable and to preserve a pencil of cubic curves. Generically, the nine base points of this pencil include three points at infinity (corresponding to the asymptotic directions of cubic curves) and six finite points lying on a conic. Read More

An easily applicable method to analyse the ankle-foot power absorption and production during walking.

Gait Posture 2019 Apr 11;71:56-61. Epub 2019 Apr 11.

Movement Biomechanics and Motor Control Lab, DEIB, Politecnico di Milano, Milan, Italy.

Background: Power and work at the ankle joint during gait are usually computed considering the foot as a rigid body [1-6] (Ankle Joint method, AJ). The foot is instead a deformable structure and can absorb and produce work by pronation/supination, foot arch deformation and other intrinsic movements. A different approach, named "the Distal Shank method (DS)" [7-12] considers all these aspects without increasing the complexity of the protocol, and thus it seems promising for clinical applications [12].

A generally applicable atomic-charge dependent London dispersion correction.

J Chem Phys 2019 Apr;150(15):154122

Mulliken Center for Theoretical Chemistry, Institut für Physikalische und Theoretische Chemie der Universität Bonn, Beringstr. 4, D-53115 Bonn, Germany.

The so-called D4 model is presented for the accurate computation of London dispersion interactions in density functional theory approximations (DFT-D4) and generally for atomistic modeling methods. In this successor to the DFT-D3 model, the atomic coordination-dependent dipole polarizabilities are scaled based on atomic partial charges which can be taken from various sources. For this purpose, a new charge-dependent parameter-economic scaling function is designed. Read More

Using a hybrid read-across method to evaluate chemical toxicity based on chemical structure and biological data.

Ecotoxicol Environ Saf 2019 Apr 17;178:178-187. Epub 2019 Apr 17.

Center for Computational and Integrative Biology, Rutgers University, Camden, NJ, USA; Department of Chemistry, Rutgers University, Camden, NJ, USA. Electronic address:

Read-across has become a primary approach to fill data gaps for chemical safety assessments. Chemical similarity based on structure, reactivity, and physic-chemical property information is a traditional approach applied for read-across toxicity studies. However, toxicity mechanisms are usually complicated in a biological system, so only using chemical similarity to perform the read-across for new compounds was not satisfactory for most toxicity endpoints, especially when the chemically similar compounds show dissimilar toxicities.

A new adhesive bone conduction hearing system effectively treats conductive hearing loss in children.

Int J Pediatr Otorhinolaryngol 2019 Apr 3;122:117-125. Epub 2019 Apr 3.

Department of Otorhinolaryngology, Head and Neck Surgery, St. Elisabeth-Hospital, Ruhr University Bochum, Bochum, Germany.

Objectives: Bone conduction hearing devices integrated in softbands (BCDSs) are frequently not well accepted by children with conductive hearing loss due to pressure on the head, sweating, or cosmetic stigma. A non-surgical hearing system (ADHEAR) uses a new bone conduction concept consisting of an audio processor connected to an adhesive adapter fixed behind the ear. This study is the first to evaluate the audiological and clinical outcome of this novel system, comparing it with conventional BCDSs in a short- and mid-term follow-up in children under 10 years of age.

Identification of sugar response complex in the metallothionein OsMT2b gene promoter for enhancement of foreign protein production in transgenic rice.

Plant Cell Rep 2019 Apr 19. Epub 2019 Apr 19.

Department of BioAgricultural Sciences, National Chiayi University, Chiayi, 60004, Taiwan.

Key Message: A 146-bp sugar response complex MTSRC is identified in the promoter of rice metallothionein OsMT2b gene conferring high-level expression of luciferase reporter gene and bioactive recombinant haFGF in transgenic rice. A rice subfamily type 2 plant metallothionein (pMT) gene, OsMT2b, encoding a reactive oxygen species (ROS) scavenger protein, has been previously shown to exhibit the most abundant gene expression in young rice seedling. Expression of OsMT2b was found to be regulated negatively by ethylene and hydrogen peroxide in rice stem node under flooding stress, but little is known about its response to sugar depletion.

Applicability of the mutation-selection balance model to population genetics of heterozygous protein-truncating variants in humans.

Mol Biol Evol 2019 Apr 19. Epub 2019 Apr 19.

Brigham and Women's Hospital, Division of Genetics, Harvard Medical School, Boston, MA, USA.

The fate of alleles in the human population is believed to be highly affected by the stochastic force of genetic drift. Estimation of the strength of natural selection in humans generally necessitates a careful modeling of drift including complex effects of the population history and structure. Protein-truncating variants (PTVs) are expected to evolve under strong purifying selection and to have a relatively high per-gene mutation rate. Read More

On Behind the Physics of the Thermoelectricity of Topological Insulators.

Sci Rep 2019 Apr 19;9(1):6324. Epub 2019 Apr 19.

Departamento de Física Aplicada, Instituto de Investigacións Tecnolóxicas. Universidade de Santiago de Compostela, E-15782, Campus Vida s/n, Santiago de Compostela, Spain.

Topological Insulators are the best thermoelectric materials involving a sophisticated physics beyond their solid state and electronic structure. We show that exists a topological contribution to the thermoelectric effect that arises between topological and thermal quantum field theories applied at very low energies. This formalism provides us with a quantized topological mass proportional to the temperature T leading, through an electric potential V, to a Seebeck coefficient where we identify an anomalous contribution that can be associated to the creation of real electron-hole Schwinger's pairs close to the topological bands.

Ultrasonic Vascular Vector Flow Mapping for 2-D Flow Estimation.

Ultrasound Med Biol 2019 Apr 16. Epub 2019 Apr 16.

Healthcare Business Unit, Hitachi, Ltd., Tokyo, Japan.

A vascular vector flow mapping (VFM) method visualizes 2-D cardiac flow dynamics by estimating the radial component of flow from the Doppler velocities and wall motion velocities using the mass conservation equation. Although VFM provides 2-D flow, the algorithm is applicable only to bounded regions. Here, a modified VFM algorithm, vascular VFM, is proposed so that the velocities are estimated regardless of the flow geometry. Read More

Allele Frequency Difference ⁻An Intuitive Alternative to for Quantifying Genetic Population Differentiation.

Authors:
Daniel Berner

Genes (Basel) 2019 Apr 18;10(4). Epub 2019 Apr 18.

Department of Environmental Sciences, Zoology, University of Basel, Vesalgasse 1, CH-4051 Basel, Switzerland.

Measuring the magnitude of differentiation between populations based on genetic markers is commonplace in ecology, evolution, and conservation biology. The predominant differentiation metric used for this purpose is F. Based on a qualitative survey, numerical analyses, simulations, and empirical data, I here argue that F does not express the relationship to allele frequency differentiation between populations generally considered interpretable and desirable by researchers.
