Noninvasive techniques for prevention of intradialytic hypotension

Episodes of hypotension during hemodialysis treatment constitutes an important clinical problem which has received considerable attention in recent years. Despite the fact that numerous approaches to reducing the frequency of intradialytic hypotension (IDH) have been proposed and evaluated, the problem has not yet found a definitive solution--an observation which, in particular, applies to episode

Meru couples planar cell polarity with apical-basal polarity during asymmetric cell division

Polarity is a shared feature of most cells. In epithelia, apical-basal polarity often coexists, and sometimes intersects with planar cell polarity (PCP), which orients cells in the epithelial plane. From a limited set of core building blocks (e.g. the Par complexes for apical-basal polarity and the Frizzled/Dishevelled complex for PCP), a diverse array of polarized cells and tissues are generated.

Drug effect evaluation during permanent atrial fibrillation using an AV-node model

The purpose of the present study is to evaluate the effect of rate control drugs on the AV node characteristics during atrial fibrillation (AF) using a model-based approach. A statistical model of the AV nodal function is employed, defined by parameters which characterize the arrival rate of atrial impulses, the refractoriness of the fast and the slow AV-nodal pathway and the probability of atrial

Atrial Impulses at the Atrioventricular Node: Arrival versus Conduction during Atrial Fibrillation

The atrioventricular (AV) node plays a central role during atrial fibrillation (AF).We have recently proposed a statistical AV node model defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing the slower of the two AV nodal pathways, the refractory periods of the pathways, and the prolongation of refractory periods. All model parameters are

Statistical modeling of atrioventricular nodal function during atrial fibrillation : An update

This paper introduces a number of advancements of our recently proposed model of atrioventricular (AV) node function during atrial fibrillation (AF). The model is defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing either one of the two AV nodal pathways, the refractory periods of these pathways, and their prolongation. In the updated mo

Architecture Design of a Memory Subsystem for Massive MIMO Baseband Processing

This brief presents an on-chip memory subsystem for massive multiple-input-multiple-output (MIMO) baseband processing at the base station. In massive MIMO systems, the required memory bandwidth and capacity are orders of magnitude higher than those used in conventional wireless systems, due to the large number of serving antennas. These are further combined with design targets on low access latenc

Äldre kyrklig konst på Historiska museet i Lund : en katalog

Samlingen av medeltida kyrklig konst från Skåne på Historiska museet i Lund är unik sett till både kvantitet och kvalitet. Här finns nära en tredjedel av landskapets kyrkor representerade och träskulpturen omspänner allt från verk av lokala konstnärer till firade mästare från kontinenten. På museets tredje våning kan besökaren se det mesta och det bästa i en närmast tidlös installation, designad a

Medieval church art at the Historical Museum in Lund : a catalogue

The collection of medieval Scanian church art at the Historical museum of Lund is unique as to both quantity and quality. Here, nearly a third of the churches in the province are represented and the wood sculpture encompasses everything from works by local artists to celebrated masters from the continent. On the second floor of the museum the visitor can see most and the best of it in a nearly tim

The Historical Museum and archaeological research at Lund University 1805-2005

"This account of the Historical Museum and Archaeological Research at Lund University 1805-2005 consists of two parts; a reprint of the history of the Museum including the Archaeological Department until 1984, published that year, and a part comprimising the development during the subsequent twenty years. It describes and discusses the changges and, if possible, the causes of change.The author, Be

What's normal? Immune profiling of human milk from healthy women living in different geographical and socioeconomic settings

Human milk provides a very wide range of nutrients and bioactive components, including immune factors, human milk oligosaccharides, and a commensal microbiota. These factors are essential for interconnected processes including immunity programming and the development of a normal infant gastrointestinal microbiome. Newborn immune protection mostly relies on maternal immune factors provided through

Serum microRNAs in male subfertility—biomarkers and a potential pathogenetic link to metabolic syndrome

Purpose: The purpose of the study was to identify serum microRNAs providing a link between male subfertility and metabolic syndrome (MetS) and validate their diagnostic potential. Methods: Sera were analyzed for fertility and MetS-related parameters in subfertile men (n = 79) and controls (n = 38). Literature review identified miR-155-5p, miR-122-5p, miR-200a-3p, and miR-200c-3p which previously w

Can flavonoid-rich chocolate modulate arterial elasticity and pathological uterine artery Doppler blood flow in pregnant women? A pilot study

Introduction: Dark chocolate has shown beneficial effects on cardiovascular health and might also modulate hypertensive complications in pregnancy and uteroplacental blood flow. Increased uteroplacental resistance is associated with systemic arterial stiffness. We aimed to investigate the short-term effect of flavonoid-rich chocolate on arterial stiffness and Doppler blood flow velocimetry indexes

Family history of cardiometabolic diseases and its association with arterial stiffness in the Malmö Diet Cancer cohort

OBJECTIVE:: Arterial stiffening increases with age and is associated with increased cardiovascular risk. Several risk factors have been shown to predict the development of arterial stiffening; however, a positive family history (FH+) of cardiometabolic disease (CMD) and hypertension has not been extensively studied. We hypothesize that FH+ of CMD plays a significant role in the development of arte

Dynamic high-sensitivity troponin elevations in atrial fibrillation patients might not be associated with significant coronary artery disease

Background: Since the introduction of high-sensitivity troponin assays a greater proportion of atrial fibrillation (AF) patients present with dynamic troponin elevations. We hypothesize that significant coronary artery disease (CAD) causes relative ischemia in the setting of a rapid heart rate resulting in dynamic troponin elevation. The aim of this study was to examine if patients without known C
