Heart Rate Estimation from Dual Pressure Sensors of a Dialysis Machine

Dialysis patients often suffer from cardiovascular dis- eases, motivating the use of continuous monitoring of car- diac activity in clinical routine. Cardiac pressure pulses propagate through the vascular system and enter the ex- tracorporeal blood circuit of a dialysis machine, where the pulses are captured by pressure sensors. The cardiac pulses are obscured by the much stronger pressure pulses

Genetic loci for bone architecture determined by three-dimensional CT in crosses with the diabetic GK rat.

The F344 rat carries alleles contributing to bone fragility while the GK rat spontaneously develops type-2 diabetes. These characteristics make F344xGK crosses well suited for the identification of genes related to bone size and allow for future investigation on the association with type-2 diabetes. The aim of this study was to identify quantitative trait loci (QTLs) for bone size phenotypes measu

Regional integration and productivity growth: The case of the EU

Recent research has emphasised the role of trade in productivity growth. The purpose of the present paper is to investigate how regional integration, and the different treatment of member and non-member imports, affects the relation between imports and productivity growth. We focus on the European Union and find intra-union imports to have more of an effect on total factor productivity growth than

Multifocal electroretinogram for functional evaluation of retinal injury following ischemia-reperfusion in pigs.

BACKGROUND: Multifocal electroretinogram (mfERG) has the power to discriminate between localized functional losses and overall retinal changes when evaluating retinal injury. So far, full-field ERG has been the gold standard for examining retinal ischemia and the effects of different neuroprotectants in experimental conditions. The aim of the present study was to establish mfERG, with simultaneous

0250 Occupational exposure and stroke - A critical review of chemical and physical exposures.

Stroke is the third most common cause of death in developed countries, exceeded only by coronary heart disease and cancer. There is substantial scientific literature on the association between occupational exposures and coronary heart disease, but much less is known about stroke. This systematic critical review was performed to assess the strength of evidence for causal associations between chemic

Predictive Validity and Cut-Off Scores in Four Diagnostic Tests for Falls – A Study in Frail Older People at Home

No study has investigated the predictive validity and cut-off scores in diagnostic tests for falls used in in-home assessment in frail older people. The objective was to investigate the predictive validity for falls in the Downton Fall Risk Index (DFRI), Timed Up and Go (TUG) and Romberg test (RT) used in in-home assessment of frail older people (65+ years). Data on the diagnostic tests were colle

Neurogenin2 directs granule neuroblast production and amplification while NeuroD1 specifies neuronal fate during hippocampal neurogenesis.

The specification and differentiation of dentate gyrus granule neurons in the hippocampus require temporally and spatially coordinated actions of both intrinsic and extrinsic molecules. The basic helix-loop-helix transcription factor Neurogenin2 (Ngn2) and NeuroD1 are key regulators in these processes. Based on existing classification, we analyzed the molecular events occurring during hippocampal

Microwave-assisted rapid characterization of lipase selectivities.

A rapid screening procedure for characterization of lipase selectivities using microwaves was developed. The rate of reaction of various commercial lipases (porcine pancreas, Mucor miehei, Candida rugosa, Pseudomonas cepacia) as well as lipases from laboratory isolates-Bacillus stearothermophilus and Burkholderia cepacia RGP-10 for triolein hydrolysis was 7- to 12-fold higher in a microwave oven a

The bootstrap particle filtering bias

Particle filter methods constitute a class of iterative genetic-type algorithms which provide powerful tools for obtaining approximate solutions to non-linear and/or non-Gaussian filtering problems. The aim of this paper is to, using standard tools from probability theory, study the bias of Monte Carlo integration estimates obtained by the bootstrap particle filter. A bound on this bias, which is

Systematic Analysis of MicroRNAs Targeting the Androgen Receptor in Prostate Cancer Cells.

Androgen receptor (AR) is expressed in all stages of prostate cancer progression, including in castration-resistant tumors. Eliminating AR function continues to represent a focus of therapeutic investigation, but AR regulatory mechanisms remain poorly understood. To systematically characterize mechanisms involving microRNAs (miRNAs), we conducted a gain-of function screen of 1129 miRNA molecules i
