Evidence for the formation of comet 67p/churyumov-gerasimenko through gravitational collapse of a bound clump of pebbles

The processes that led to the formation of the planetary bodies in the Solar system are still not fully understood. Using the results obtained with the comprehensive suite of instruments onboard the European Space Agency's Rosetta mission, we present evidence that comet 67P/Churyumov-Gerasimenko likely formed through the gentle gravitational collapse of a bound clump of mm-sized dust aggregates ('

Study protocol for an observational register-based study on health and risk factors in patients with hip and knee osteoarthritis

INTRODUCTION: Hip and knee osteoarthritis is a leading cause of disability worldwide. Currently, the course of deterioration in pain and physical functioning in individuals with osteoarthritis is difficult to predict. Factors such as socioeconomic status and comorbidity contribute to progression of osteoarthritis, but clear associations have not been established. There is a need for early identifi

Risk of bladder cancer by disease severity in relation to metabolic factors and smoking : A prospective pooled cohort study of 800,000 men and women

Previous studies on metabolic factors and bladder cancer (BC) risk have shown inconsistent results and have commonly not investigated associations separately by sex, smoking, and tumor invasiveness. Among 811,633 participants in six European cohorts, we investigated sex-specific associations between body mass index (BMI), mid-blood pressure (BP, [systolic + diastolic]/2), plasma glucose, triglycer

In vitro digestion rate and resistant starch content of tortillas stored at two different temperatures

In vitro indicators of starch bioavailability were evaluated in freshly prepared maize tortillas and compared to those exhibited by 24, 48 or 72 h-stored samples. Storage took place either at room temperature (approx. 25 °C) or under refrigeration (4 °C). Potentially available starch (AS) content decreased from 670 g kg-1 in the control tortilla to 583 g kg-1 in 72 h-stored preparations. Concomita

The remote exercise SWEDEHEART study–Rationale and design of a multicenter registry-based cluster randomized crossover clinical trial (RRCT)

Background: Despite proven benefits of exercise-based cardiac rehabilitation (EBCR), few patients with myocardial infarction (MI) participate in and complete these programs. Study design and objectives: The Remote Exercise SWEDEHEART study is a large multicenter registry-based cluster randomized crossover clinical trial with a planned enrollment of 1500 patients with a recent MI. Patients at inter

Effects of wing damage and moult gaps on vertebrate flight performance

Vertebrates capable of powered flight rely on wings, muscles that drive their flapping and sensory inputs to the brain allowing for control of the motor output. In birds, the wings are formed of arrangements of adjacent flight feathers (remiges), whereas the wings of bats consist of double-layered skin membrane stretched out between the forelimb skeleton, body and legs. Bird feathers become worn f

Augmented reality face recognition for musical interaction

This paper reports on early work in a project devoted to the exploration of music, musical quality, interaction design and sensory stimulation for persons with multiple and/or severe impairments. The text focuses on the explorative work done on using face tracking and face recognition for musical interaction. The current design and the design process so far is described. Further developments are o

Pressure injuries are common in children with myelomeningocele : Results from a follow-up programme and register

AIM: To investigate the occurrence of pressure injuries (PIs) in children with myelomeningocele (MMC) and to investigate the association between PIs and orthoses use by disability-specific variables.METHODS: Population-based registry study including participants in the Swedish multidisciplinary follow-up programme for MMC. Risks of PIs were investigated by birth cohort, country of birth, sex, type

Quantification Of Glycosaminoglycans In Knee Synovial Fluid From Different Patient Groups And Knee-Healthy Subjects Using High Performance Liquid Chromatography

Purpose: The glycosaminoglycans chondroitin sulfate (CS) and hyaluronic acid (HA) are important for the normal function of articular cartilage, and changes of their sulfation and concentration may play a role in the pathogenesis of osteoarthritis (OA). Therefore, these glycans may be clinically useful as biomarkers in OA management. The purpose of this study was to analyze the CS and HA pattern in

Technical performance of a proximity extension assay inflammation biomarker panel with synovial fluid

The plasma proteome can provide a deeper understanding of the pathophysiology of different diseases and is a key source for detection of new biomarkers. Proximity extension assay (PEA), developed by Olink Proteomics (Uppsala, Sweden), detects proteins by using pairs of antibodies that are linked to oligonucleotides; upon target binding, the probes anneal when in proximity and the oligonucleotides

The genetic contribution to hand osteoarthritis

Objective: To estimate the genetic contribution to doctor-diagnosed hand osteoarthritis (OA). Methods: Using data from the Swedish Twin Registry and National Patient Register, we conducted a 20-year population-based longitudinal cohort study including 59,970 twins aged 35 years or older. We studied inpatient and outpatient doctor-diagnosed hand OA using ICD-10 codes from 1997 until 2016, including

Polypharmacy and adverse outcomes after hip fracture surgery

Background: We aimed to explore the effects of polypharmacy and specific drug classes on readmissions and mortality after hip surgery. Methods: We analyzed data on 272 consecutive hip fracture patients (72.1% females; age 82±9 years) who underwent acute hip replacement. We collected detailed data on the pharmacological treatment upon admission and discharge. Patients were followed up over a period

Filling the Gap – Improving Awareness and Practice in Hyponatraemia and the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) in the Older Patient : A European Consensus View

Introduction: Causes of hyponatraemia in older patients are multivariate and in the case of SIADH may often be drug induced. Diagnostic and treatment algorithms are unclear for this important age group. Methods: The author group identified 6 broad themes for consensus and formulated 42 separate consensus statements within these 6 themes. Statements were then circulated to geriatricians, general p

Insulin resistance and β-cell function in smokers : Results from the EGIR-RISC European multicentre study

Aims: Tobacco smoking is known to increase the long-term risk of developing Type 2 diabetes mellitus, but the mechanisms involved are poorly understood. This observational, cross-sectional study aims to compare measures of insulin sensitivity and β-cell function in current, ex- and never-smokers. Methods: The study population included 1246 people without diabetes (mean age 44 years, 55% women) fro

Modular and hierarchical specialization in neural networks

Modularity and hierarchy are fundamental notions in structured system design. By subdividing a large and unstructured problem into smaller and tractable chunks, design automation becomes possible. In this paper we discuss the use of modularity and hierarchy for functional specialization during the development of neural networks. We study the behavioral differences and requirements for back-propaga
