Effects of surface pressure and internal friction on the dynamics of shear-driven supported lipid bilayers

Supported lipid bilayers (SLBs) are one of the most common model systems for cell membrane studies. We have previously found that when applying a bulk flow of liquid above an SLB the lipid bilayer and its constituents move in the direction of the bulk flow in a rolling type of motion, with the lower monolayer being essentially stationary. In this study, a theoretical platform is developed to model

Complement C4d-specific antibodies for the diagnosis of lung cancer

Development of molecular markers that help to identify high-risk individuals or diagnose indeterminate pulmonary nodules could have a major impact on lung cancer clinical management. In this study, we evaluated the diagnostic potential of a newly-developed ELISA that specifically detects complement C4d. We measured this marker in five independent cohorts of plasma and bronchoalveolar lavage sample

PREPL deficiency : Delineation of the phenotype and development of a functional blood assay

PurposePREPL deficiency causes neonatal hypotonia, ptosis, neonatal feeding difficulties, childhood obesity, xerostomia, and growth hormone deficiency. Different recessive contiguous gene deletion syndromes involving PREPL and a variable combination of SLC3A1 (hypotonia-cystinuria syndrome), CAMKMT (atypical hypotonia-cystinuria syndrome), and PPM1B (2p21 deletion syndrome) have been described. In

Studies on the Proteome of Human Hair - Identification of Histones and Deamidated Keratins

Human hair is laminar-fibrous tissue and an evolutionarily old keratinization product of follicle trichocytes. Studies on the hair proteome can give new insights into hair function and lead to the development of novel biomarkers for hair in health and disease. Human hair proteins were extracted by detergent and detergent-free techniques. We adopted a shotgun proteomics approach, which demonstrated

Cross-Correlation of Large-Scale Parameters in Multi-Link Systems : Analysis using the Box-Cox Transformation

Spatially distributed transmission points connected to the same source, known as distributed antenna systems, can improve system performance compared to single-link traditional systems. However, the anticipated gain depends heavily on the cross-correlation properties of the large-scale parameters (LSPs) of the different links. Usually, measured LSPs—except the large-scale fading&#x2

A Simplified Model to Simulate pH and Alkalinity in the Mixing Zone Downstream of an Acidic Discharge

A modelling methodology was developed that simulates the resulting pH and alkalinity in the mixing zone when acidic water is discharged into a river. The input to the model are the: pH, alkalinity, flow, and temperature of both the river water and the acidic discharge. Two different scenarios were simulated: (1) a change of pH in the acidic discharge, assuming constant flow; and (2) a change in th

Barriers to immunization among newcomers : A systematic review

Introduction: Currently, there is a lack of comprehensive evidence exploring vaccine decision-making among newcomers. We conducted a systematic review of qualitative studies aimed at identifying factors that influence newcomers' decision-making with regards to vaccination. Methods: We conducted a search of MEDLINE, EMBASE, CINAHL and Cochrane Central. To be included, studies needed to employ a qua

Exercise self-efficacy in adults with congenital heart disease

Background Physical activity improves health, exercise tolerance and quality of life in adults with congenital heart disease (CHD), and exercise training is in most patients a high-benefit low risk intervention. However, factors that influence the confidence to perform exercise training, i.e. exercise self-efficacy (ESE), in CHD patients are virtually unknown. We aimed to identify factors related

Targeted proteomic analysis of habitual coffee consumption

Background: Coffee drinking has been implicated in mortality and a variety of diseases but potential mechanisms underlying these associations are unclear. Large-scale systems epidemiological approaches may offer novel insights to mechanisms underlying associations of coffee with health. Objective: We performed an analysis of known and novel protein markers linked to cardiovascular disease and thei

Energy-Optimal Data Aggregation and Dissemination for the Internet of Things

Established approaches to data aggregation in wirelesssensor networks (WSNs) do not cover the variety of new usecases developing with the advent of the Internet of Things. In particular,the current push towards fog computing, in which control,computation, and storage are moved to nodes close to the networkedge, induces a need to collect data at multiple sinks, ratherthan the single sink typically

Potentially inappropriate medication among people with dementia in eight European countries

Objectives: to evaluate the frequency of potentially inappropriate medication (PIM) prescription among older people with dementia (PwD) from eight countries participating in the European study 'RightTimePlaceCare', and to evaluate factors and adverse outcomes associated with PIM prescription.Methods: survey of 2,004 PwD including a baseline assessment and follow-up after 3 months. Interviewers gat

Studying retrograde signaling in plants

Cellular homeostasis requires precise communication between various types of organelles. In particular, the communication between nucleus and semiautonomous organelles, mitochondria and chloroplasts, has received widespread attention. Communication from nucleus to other organelles is known as anterograde signaling, whereas communication from mitochondria or chloroplasts to the nucleus is known as

The Paediatric Cataract Register (PECARE) : an overview of operated childhood cataract in Sweden and Denmark

Aim: To report basic epidemiological data concerning surgically treated childhood cataract in Sweden and Denmark. Methods: Data were derived from the Paediatric Cataract Register (PECARE), a binational, web-based surgical register representing Sweden and Denmark. All children operated before 8 years of age between 1 January 2007 and 31 December 2013 were included. Age-specific prevalence per 100 0

Signals of sedentism : Faunal exploitation as evidence of a delayed-return economy at Norje Sunnansund, an Early Mesolithic site in south-eastern Sweden

Delayed-return foraging strategies connected with a sedentary lifestyle are known from Late Mesolithic Scandinavian settlements. However, recent evidence from the archaeological site of Norje Sunnansund, in south-eastern Sweden, indicates the presence of sedentism from the Early Mesolithic. By analyzing the faunal assemblage from Norje Sunnansund, patterns of delayed-return strategies were examine

Femtosecond laser–assisted cataract surgeries reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery : Baseline characteristics, surgical procedure, and outcomes

Purpose To describe a large cohort of femtosecond laser–assisted cataract surgeries in terms of baseline characteristics and the related outcomes. Setting Eighteen cataract surgery clinics in 9 European countries and Australia. Design Prospective multicenter case series. Methods Data on consecutive eyes having femtosecond laser–assisted cataract surgery in the participating clinics were entered in

Alteration of putaminal fractional anisotropy in Parkinson’s disease : a longitudinal diffusion kurtosis imaging study

Purpose: In Parkinson’s disease (PD), pathological microstructural changes occur that may be detected using diffusion magnetic resonance imaging (dMRI). However, there are few longitudinal studies that explore the effect of disease progression on diffusion indices. Methods: We prospectively included 76 patients with PD and 38 healthy controls (HC), all of whom underwent diffusion kurtosis imaging
