Dyspnoea-12 and Multidimensional Dyspnea Profile : Systematic Review of Use and Properties

Context: The Dyspnoea-12 (D-12) and Multidimensional Dyspnea Profile (MDP) were specifically developed for assessment of multiple sensations of breathlessness. Objectives: This systematic review aimed to identify the use and measurement properties of the D-12 and MDP across populations, settings and languages. Methods: Electronic databases were searched for primary studies (2008-2020) reporting us

Changes in numbers and distribution of wintering waterbirds around Gotland 1969–2020

THE COASTAL AREAS of the island of Gotland in the center of the Baltic Sea is an important wintering site for water-birds in Sweden. Gotland offers extensive areas of shallow feeding grounds and, due to its location, some open waters remain available even during harsh winters. Wintering waterbirds have been counted annually on the island since the start of the international waterbird counts in 196

Grazing incidence small angle neutron scattering as a tool to study curved biomembranes on nanostructured surfaces

Curvature in lipid-based biomembranes provides compartmentalization in cells and can act as regulator of biological activity in living systems. The study of these biomembranes require novel model systems and new methods. In this work I have used a supported phospholipid bilayer on a hexagonal array of silicon nanowires. The nanowires impose curvature on the supported lipid bilayer and the resultin

Analysis on breakup dynamics of hydrogen taylor bubble formation in a cross-junction microchannel

The pinch-off dynamics during hydrogen bubble formation was experimentally investigated in a cross-junction microchannel. A binarization interface recognizing and key frame tracking method was established. By analyzing the breakup dynamics through spatial and time domains, the effects of interfacial tension and viscosity on hydrogen bubble pinch-off were revealed. A transitional stage between a li

Is the Nagoya Protocol designed to conserve biodiversity?

We have entered a monumental era in terms of realizing the impact of biodiversity loss on our everyday lives. We suffer from the consequences of biodiversity loss due to overexploitation of natural resources as we continue failing to restore biodiversity. One of the major consequences of biodiversity loss is the emergence of global pandemics. We are in urgent need of realizing the full potential o

Decreased Pain Sensitivity and Alterations of Cerebrospinal Fluid and Plasma Inflammatory Mediators After Total Hip Arthroplasty in Patients with Disabling Osteoarthritis

Background: Proinflammatory mechanisms are implicated in pain states. Recent research indicates that patients with osteoarthritis (OA) with signs of central sensitization exhibit elevated cerebrospinal fluid (CSF) levels of interferon gamma-induced protein 10 (IP-10), Fms-related tyrosine kinase 1 (Flt-1), and monocyte chemoattractant protein 1 (MCP-1).Methods: The current prospective cohort study

Pathways linking sleep, neuroimmune signaling and pain: an integrative approach

Background and objectives: Neuroinflammation is implicated in the development and maintenance of persistent pain states, but there is limited data linking cerebrospinal fluid (CSF) inflammatory mediators with neurophysiological pain processes in humans. Study I aimed to investigate whether there are coherent changes in CSF inflammation associated with central sensitization (CS), and to evaluate po

Immune delineation of laryngeal papilloma reveals enhanced neutrophil associated gene profile

Laryngeal papilloma (LP) is a rare benign disease, caused by recurrent multisite papillomas that are referred to as recurrent respiratory papillomatosis (RRP). RRP is caused primarily by two types of human papillomavirus (HPV): HPV6 and HPV11. The immune dysregulation within the microenvironment of the lesions has been shown to likely play a role in the development of RRP. The present study aimed

Real-Time EEG-Based Cognitive Workload Monitoring on Wearable Devices

Objective: Cognitive workload monitoring (CWM) can enhance human-machine interaction by supporting task execution assistance considering the operators cognitive state. Therefore, we propose a machine learning design methodology and a data processing strategy to enable CWM on resource-constrained wearable devices. Methods: Our CWM solution is built upon edge computing on a simple wearable system, w

Authoritarianism and Immigration Attitudes in the UK

Opposition to immigration has featured prominently in the “cultural backlash” to globalization in Western nations and was a key determinant of Britain’s Brexit referendum. In this article, we draw on theories of intergroup threat to examine the effect of “right-wing authoritarianism” on immigration attitudes in the UK. Previous research suggests that cultural aspects of immigration are especially

Payment Systems as a Driver for Platform Growth in E-Commerce: Network Effects and Business Models

This chapter visits some of the fundamental concepts from platform economics, network effects, and network externalities. Further on, it discusses definitions of two-sided and multi-sided markets, how they are treated as business models. These concepts are further compared to the concept service ecosystem. A case of a payment service provider whose business model contributes to the growth of e-com

Detection of bacterial DNA in synovial fluid in dogs with arthritis : a comparison between bacterial culture and 16S rRNA polymerase chain reaction

Background: Septic arthritis (SA) is a serious condition in dogs that requires a prompt diagnosis and treatment to minimize long-term joint pathology. Although bacterial detection in synovial fluid (SF) through culture or cytology is often performed to confirm diagnosis, the sensitivity of these tests is low. The need for a reliable diagnostic tool to confirm the presence of bacteria in SF in huma

Asymmetric Spacer in Dion–Jacobson Halide Perovskites Induces Staggered Alignment to Direct Out-of-Plane Carrier Transport and Enhance Ambient Stability Simultaneously

Dion–Jacobson (DJ)-type 2D halide perovskites present superior environmental stability and a narrower bandgap, yet a contradiction between charge transport and stability remains to be resolved. Herein, it is shown that both symmetry and substitution of the organic spacer in DJ perovskites synergistically direct the narrow interlayer spacing, staggered spacer alignment, and regular phase arrangemen

How are reasons for encounter associated with influenza-like illness and acute respiratory infection diagnoses and interventions? A cohort study in eight Italian general practice populations

Background: Influenza-like illness (ILI) and Acute Respiratory Infections (ARI) are a considerable health problem in Europe. Most diagnoses are made by family physicians (FPs) and based on symptoms and clinical signs rather than on diagnostic testing. The International Classification of Primary Care (ICPC) advocates that FPs record patients’ ‘Reasons for Encounters’ (RfEs) as they are presented to

Safety Aspects of Perinatal Ultrasound

Ultrasound safety is of particular importance in fetal and neonatal scanning. Fetal tissues are vulnerable and often still developing, the scanning depth may be low, and potential biological effects have been insufficiently investigated. On the other hand, the clinical benefit may be considerable. The perinatal period is probably less vulnerable than the first and second trimesters of pregnancy, a

A quality optimization approach to image Achilles tendon microstructure by phase-contrast enhanced synchrotron micro-tomography

Achilles tendons are mechanosensitive, and their complex hierarchical structure is in part the result of the mechanical stimulation conveyed by the muscles. To fully understand how their microstructure responds to mechanical loading a non-invasive approach for 3D high resolution imaging suitable for soft tissue is required. Here we propose a protocol that can capture the complex 3D organization of
