Detection of systolic ejection click using time growing neural network.

In this paper, we present a novel neural network for classification of short-duration heart sounds: the time growing neural network (TGNN). The input to the network is the spectral power in adjacent frequency bands as computed in time windows of growing length. Children with heart systolic ejection click (SEC) and normal children are the two groups subjected to analysis. The performance of the TGN

Biomarker discovery study design for type 1 diabetes in The Environmental Determinants of Diabetes in the Young (TEDDY) study

Aims The Environmental Determinants of Diabetes in the Young planned biomarker discovery studies on longitudinal samples for persistent confirmed islet cell autoantibodies and type 1 diabetes using dietary biomarkers, metabolomics, microbiome/viral metagenomics and gene expression. Methods This article describes the details of planning The Environmental Determinants of Diabetes in the Young biomar

Human Leukocyte Antigen Matching in Heart Transplantation: Systematic Review and Meta-analysis.

Allocation of donors with regard to human leukocyte antigen (HLA) is controversial in heart transplantation. This paper is a systematic review and meta-analysis of the available evidence. PubMed, Embase, and the Cochrane Library were searched systematically for studies that addressed the effects of HLA matching on outcome after heart transplantation. Fifty-seven studies met the eligibility criteri

Reduced morbidity at diagnosis and improved glycemic control in children previously enrolled in DiPiS follow-up

Aims/hypothesis: Children participating in longitudinal type 1 diabetes prediction studies were reported to have less severe disease at diabetes diagnosis. Our aim was to investigate children who from birth participated in the Diabetes Prediction in Skane (DiPiS) study for metabolic status at diagnosis and then continued to be followed for 2 yr of regular clinical care. Methods: Children, followed

Psychometric properties of the Swedish version of the Scleroderma Health Assessment Questionnaire and the Cochin Hand Function Scale in patients with systemic sclerosis.

Objectives: To translate the visual analogue scales (VAS) in the Scleroderma Health Assessment Questionnaire (SSc HAQ) and the Cochin Hand Function Scale (CHFS) and to examine the reliability and validity of the Swedish versions of the instruments. Method: The reproducibility, internal consistency, acceptability, and validity of the instruments were evaluated. Eighty-three consecutive patients par

Genetic linkage facilitates cloning of Ert-m regulating plant architecture in barley and identified a strong candidate of Ant1 involved in anthocyanin biosynthesis.

The erectoides-m anthocyanin-less 1 (ert-m ant1) double mutants are among the very few examples of induced double mutants in barley. From phenotypic observations of mutant plants it is known that the Ert-m gene product regulates plant architecture whereas the Ant1 gene product is involved in anthocyanin biosynthesis. We used a near-isogenic line of the cultivar Bowman, BW316 (ert-m.34), to create

Peripheral Microvascular Function is Altered in Young Individuals at Risk for Hypertrophic Cardiomyopathy and Correlates with Myocardial Diastolic Function.

Hypertrophic cardiomyopathy (HCM) is a major cause of sudden cardiac death in the young. Based on previous reports of functional abnormalities in not only coronary but also peripheral vessels in adults with HCM, we aimed to assess both peripheral vascular and myocardial diastolic function in young individuals with early stage of HCM and in individuals at risk for HCM. Children, adolescents and you

Charge transfer between the Au(111) surface and adsorbed C-60: Resonant photoemission and new core-hole decay channels

The interaction of C-60 with the Au(111) surface has been investigated using synchrotron radiation-based electron spectroscopy. Resonant photoelectron spectroscopy and autoionization spectroscopy have been used to probe the coupling between the molecule and the substrate. Three distinct high energy spectator Auger features were observed that are only evident for a monolayer of C-60 chemisorbed to

Is increased joint loading detrimental to obese patients with knee osteoarthritis? A secondary data analysis from a randomized trial

Objective: To investigate whether increased knee joint loading due to improved ambulatory function and walking speed following weight loss achieved over 16 weeks accelerates symptomatic and structural disease progression over a subsequent 1 year weight maintenance period in an obese population with knee osteoarthritis (OA). Methods: Data from a prospective study of weight loss in obese patients wi

Reproducibility of ankle dorsiflexor muscle strength measurements in individuals with post-polio syndrome

The aim of this study was to assess the reproducibility of isokinetic and isometric ankle dorsiflexor strength measurements in individuals with post-polio syndrome (PPS). Thirty-one men and women (mean age 63 +/- 7.0 years) with verified PPS, participated in an intra-rater test-retest reproducibility study. Strength of the ankle dorsiflexor muscles in both lower limbs were measured twice, seven da

Influence of hydrogen content on impact toughness of Zr-2.5Nb pressure tube alloy

Influence of hydrogen content on the impact toughness of Zr-2.5% Nb alloy was examined by carrying out instrumented drop weight tests in the temperature range of 25-250 degrees C using curved Charpy specimens fabricated from unirradiated pressure tubes of Indian Pressurized Heavy Water Reactor (IPHWR). Hydrogen content of the samples was between 10 and 170 ppm by weight (wppm). Sharp ductile-to-br

Intercomparison of cloud condensation nuclei and hygroscopic fraction measurements: Coated soot particles investigated during the LACIS Experiment in November (LExNo)

Four cloud condensation nuclei (CCN) instruments were used to sample size-selected particles prepared at the Leipzig Aerosol Cloud Interaction Simulator facility. Included were two Wyoming static diffusion CCN instruments, the continuous flow instrument built by Droplet Measurement Technologies, and the continuous flow Leipzig instrument. The aerosols were composed of ammonium sulfate, levoglucosa

Tracing the 1271-1246 Ma Central Scandinavian Dolerite Group mafic magmatism in Fennoscandia: U-Pb baddeleyite and Hf isotope data on the Moslatt and Borgefjell dolerites

Between 1271 and 1246 Ma, dolerite dykes and sills of the Central Scandinavian Dolerite Group intruded into the Fennoscandian Shield during three distinct magmatic pulses. They are distributed around five large magmatic complexes extending from Sweden to western Finland and record large-scale intracratonic tensional stress. Coeval plutonism is observed in the westernmost terrane of the Sveconorweg

Cellobiose dehydrogenase modified electrodes: advances by materials science and biochemical engineering

The flavocytochrome cellobiose dehydrogenase (CDH) is a versatile biorecognition element capable of detecting carbohydrates as well as quinones and catecholamines. In addition, it can be used as an anode biocatalyst for enzymatic biofuel cells to power miniaturised sensor-transmitter systems. Various electrode materials and designs have been tested in the past decade to utilize and enhance the dir

Acceptor switching and axial rotation of the water dimer in matrices, observed by infrared spectroscopy.

Several isotopologues of the water dimer have been studied in different matrices (Ne, Ar, Kr, and p-H(2)) at very low temperatures. A fine structure, which is more or less matrix independent and very similar for different intramolecular fundamentals of the same isotopologic dimer, is present on the high wavenumber side of the main component. The bound OD (OH) stretches of the donor have temperatur

Stroke Prevention Worldwide - What Could Make It Work?

The global burden of stroke is of continual major importance for global health. The present report addresses some of the core principles that could make stroke prevention work. The prevention of stroke shares many common features with other non-communicable diseases (NCDs); stroke prevention should therefore be part of the joint actions on NCD led by the WHO and member states. Stroke prevention is

Retinol May Counteract the Negative Effect of Cadmium on Bone

Cadmium and high vitamin A intake are both proposed risk factors for low bone mineral density (BMD), but potential interactions have not been studied. Within the Women's Health in the Lund Area, a population-based study in southern Sweden, we measured retinol in serum among 606 women aged 54-64 y. Data on BMD were measured by DXA at the distal forearm. Parathyroid hormone (PTH), bone alkaline phos
