A comparison of rule-based and centroid single-sample multiclass predictors for transcriptomic classification

MOTIVATION: Gene expression-based multiclass prediction, such as tumor subtyping, is a non-trivial bioinformatic problem. Most classifier methods operate by comparing expression levels relative to other samples. Methods that base predictions on the expression pattern within a sample have been proposed as an alternative. As these methods are invariant to the cohort composition and can be applied to

The Price of Synchrony : Evaluating the Resistive Losses in Synchronizing Power Networks

This paper investigates the resistive power losses that are incurred in keeping a network of synchronous generators in a synchronous state. These losses arise due to the transient power-flow fluctuations that occur when the system is perturbed from a synchronous state by a small transient event or in the face of persistent stochastic disturbances. We call these losses the 'price of synchrony,' as

Article leaf apoplast of field-grown potato analyzed by quantitative proteomics and activity-based protein profiling

Multiple biotic and abiotic stresses challenge plants growing in agricultural fields. Most molecular studies have aimed to understand plant responses to challenges under controlled conditions. However, studies on field-grown plants are scarce, limiting application of the findings in agricultural conditions. In this study, we investigated the composition of apoplastic proteomes of potato cultivar B

Drug company payments to General Practices in England: cross-sectional and social network analysis

Although there has been extensive research on pharmaceutical industry payments to healthcare professionals, healthcare organisations with key roles in health systems have received little attention. We seek to contribute to addressing this gap in research by examining drug company payments to General Practices in England in 2015. We combine a publicly available payments database managed by the phar

Vision-based Tracking of Surgical Motion during Live Open-Heart Surgery

AbstractBackgroundMotion tracking during live surgeries may be used to assess surgeons’ intra-operative performance, provide feedback, and predict outcome. Current assessment protocols rely on human observations, controlled laboratory settings, or tracking technologies not suitable for live operating theatres. In this study, a novel method for motion tracking of live open-heart surgery was develop

Effectiveness of smartphone-based community case management on the urgent referral, reconsultation, and hospitalization of children aged under 5 years in malawi : Cluster-randomized, stepped-wedge trial

Background: Integrated community case management (CCM) has led to reductions in child mortality in Malawi resulting from illnesses such as malaria, pneumonia, and diarrhea. However, adherence to CCM guidelines is often poor, potentially leading to inappropriate clinical decisions and poor outcomes. We determined the impact of an e-CCM app on the referral, reconsultation, and hospitalization rates

Sexual and Reproductive Health and Rights: : An Essential Element of Universal Health Coverage. Background document for the Nairobi Summit on ICPD25 - Accelerating the promise

The Nairobi Summit on ICPD25 provided an opportunity to complete the unfinished business of the International Conference on Population and Development Programme of Action and also a chance to commit to a forward-looking sexual and reproductive health and rights agenda to meet the Sustainable Development Goals and targets by 2030.This background document for the Nairobi Summit on ICPD25 was conceiv

Genotype–Phenotype Relations for the Atypical Parkinsonism Genes : MDSGene Systematic Review

This Movement Disorder Society Genetic mutation database Systematic Review focuses on monogenic atypical parkinsonism with mutations in the ATP13A2, DCTN1, DNAJC6, FBXO7, SYNJ1, and VPS13C genes. We screened 673 citations and extracted genotypic and phenotypic data for 140 patients (73 families) from 77 publications. In an exploratory fashion, we applied an automated classification procedure via a

Mapping prostatic microscopic anisotropy using linear and spherical b-tensor encoding : A preliminary study

Purpose: Tensor-valued diffusion encoding provides more specific information than conventional diffusion-weighted imaging (DWI), but has mainly been applied in neuroimaging studies. This study aimed to assess its potential for the imaging of prostate cancer (PCa). Methods: Seventeen patients with histologically proven PCa were enrolled. DWI of the prostate was performed with linear and spherical t

Transcription Factor Programming of Human Pluripotent Stem Cells to Functionally Mature Astrocytes for Monocultures and Cocultures with Neurons

Astrocytes are essential cells for normal brain functionality and have recently emerged as key players in many neurological diseases. However, the limited availability of human primary astrocytes for cell culture studies hinders our understanding of their physiology and precise role in disease development and progression. Here, we describe a detailed step-by-step protocol to rapidly and efficientl

Enhancing protein perdeuteration by experimental evolution of Escherichia coli K-12 for rapid growth in deuterium-based media

Deuterium is a natural low abundance stable hydrogen isotope that in high concentrations negatively affects growth of cells. Here, we have studied growth of Escherichia coli MG1655, a wild-type laboratory strain of E. coli K-12, in deuterated glycerol minimal medium. The growth rate and final biomass in deuterated medium is substantially reduced compared to cells grown in ordinary medium. By using

Methodology to obtain highly resolved SO2 vertical profiles for representation of volcanic emissions in climate models

In this study we describe a methodology to create high-vertical-resolution SO2 profiles from volcanic emissions. We demonstrate the method's performance for the volcanic clouds following the eruption of Sarychev in June 2009. The resulting profiles are based on a combination of satellite SO2 and aerosol retrievals together with trajectory modelling. We use satellite-based measurements, namely lida

Quantifying changes and drivers of runoff in the Kaidu River Basin associated with plausible climate scenarios

Study region: The Kaidu River Basin (KRB) is located on the central southern slope of the Tianshan Mountain in Northwest China. Study focus: This work aimed to assess changes and main drivers of snowmelt-driven runoff in KRB associated with three future climate scenarios. Six versions of the “Cemaneige” snowmelt module embedded in the hydrological model “GR4J” were calibrated and evaluated. The bi

An Unconditional Quantile Regression Based Decomposition of Spatial Welfare Inequalities in Ghana

Ghana has witnessed tremendous economic growth since the 1990s and attained the Millennium Development Goals target of halving poverty. This notwithstanding, inequality in Ghana increased over the same period, suggesting growth benefits were not equitably distributed. This study provides evidence on the determinants of household consumption expenditure and factors that explain rural-urban welfare

A lifestyle intervention with an energy-restricted Mediterranean diet and physical activity enhances HDL function : a substudy of the PREDIMED-Plus randomized controlled trial

BACKGROUND: Consumption of a Mediterranean diet, adequate levels of physical activity, and energy-restricted lifestyle interventions have been individually associated with improvements in HDL functions. Evidence of intensive interventions with calorie restriction and physical activity is, however, scarce. OBJECTIVES: To determine whether an intensive lifestyle intervention with an energy-restricte

Investigation of possible underlying mechanisms behind water-induced glucose reduction in adults with high copeptin

Elevated copeptin, a surrogate marker of vasopressin, is linked to low water intake and increased diabetes risk. Water supplementation in habitual low-drinkers with high copeptin significantly lowers both fasting plasma (fp) copeptin and glucose. This study aims at investigating possible underlying mechanisms. Thirty-one healthy adults with high copeptin (> 10.7 pmol·L−1 (men), > 6.1 pmol−1 (women
