Ventricular fibrillation (VF) during reperfusion (rVF) in ST-segment elevation myocardial infarction (STEMI) is an infrequent but serious event that complicates coronary interventions. The aim of this study was to analyze clinical predictors of rVF in an unselected population of patients with STEMI treated with percutaneous coronary intervention (PCI). Consecutive patients with STEMI admitted to a

The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at root s(NN) = 2: 76 TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies

Raised blood pressure (BP) is a major risk factor for cardiovascular disease. Previous studies have identified 47 distinct genetic variants robustly associated with BP, but collectively these explain only a few percent of the heritability for BP phenotypes. To find additional BP loci, we used a bespoke gene-centric array to genotype an independent discovery sample of 25,118 individuals that combin

Infections in cystic fibrosis (CF), often involving Pseudomonas aeruginosa, result from a dysregulated airway immunity where one hallmark is the accumulation of necrotic and apoptotic immune cells, in particular neutrophils. In addition, neutrophils actively release DNA, forming neutrophil extracellular traps (NETs) that contain antimicrobial proteins. Altogether, free DNA in complex with actin ac

Platelets have been reported to contribute to inflammation and inflammatory disorders. In the present study, we demonstrate that platelets contribute to the acute response to bacterial infection in a mouse model of invasive Streptococcus pyogenes infection. Thrombocytopenia occurred rapidly in infected animals and this was associated with platelet activation, formation of platelet-neutrophil compl

Background: Alloreactive memory T cells are a major obstacle to transplantation acceptance due to their capacity for accelerated rejection. Methods: C57BL/6 mice that had rejected BALB/c skin grafts 4 weeks earlier were used as recipients. The recipient mice were treated with anti-CD154/LFA-1 with or without anti-CD70 during the primary skin transplantation and anti-CD154/LFA-1 or not during the s

This article seeks to advance existing research on conditional cash transfers (CCTs) by centring the analysis of their long-term impact on the reproduc- tion of poverty and exclusion. To date, most analyses and assessments of CCTs’ long-term impact have been based on simulations focused on specific parameters such as income changes and educational attainment. This study takes as its starting point

Abstract Objective. Previous studies have identified a significant volume-outcome relationship for hospitals performing pancreaticoduodenectomy (PD). However, scant information exists concerning the effects of increased caseload of PD within the same hospital. Here, we describe the effects of becoming a high-volume provider of PD. Material and methods. The study group comprised 221 patients who un

This paper presents a general criterion to classify a channel as micro-channel or macro-channel. Experimental results of saturated-flow boiling heat transfer in micro/mini-channels for both multi- and single-channel configurations were obtained from the literature. The collected database contains 4228 data points, covering a wide range of working fluids, operational conditions, and different micro

AimTo assess which factors are associated with change in quality of life of people with dementia who have recently been admitted to long-term care facilities. BackgroundMany people with dementia will be admitted to long-term care facilities at some point during their disease. It is currently unknown which factors are associated with improvement and/or deterioration of quality of life immediately f

Co-adsorption reactions between metal ions and anionic ligands play important roles in controlling availability and transport of chemical species in natural aquatic environments as well as in industrial processes. A molecular understanding of the properties of the surface species formed provides means to model these reactions in a predictive manner and to exploit them in synthetic routes of modifi

From 1989 to 2004 the donor community provided approximately $400 billion in debt relief to developing countries in an attempt to promote growth and reduce poverty. Using a sample of 118 developing countries, this paper empirically assesses the impact of debt relief on growth via (1) resources made available for investment from reduced debt service payments and (2)improved incentives to invest fro

Gemcitabine requires transporter proteins to cross cell membranes. Low expression of human equilibrative nucleoside transporter-1 (hENT1) may result in gemcitabine resistance in pancreatic ductal adenocarcinoma (PDAC). CO-101, a lipid-drug conjugate of gemcitabine, was rationally designed to enter cells independently of hENT1. We conducted a randomized controlled trial to determine whether CO-101

Acoustic standing wave technology combined with ligand complexed microbeads offers a means for affinity specific selection of target analytes from complex samples. When realized in a microfluidic format we can capitalize on laminar flow and acoustic forces that can drive cells or microbeads across fluid interfaces. Given this, we have the ability to perform carrier fluid (suspending medium) exchan

Along with chronic neurotoxic effects, the long-term consumption of amphetamines has been associated to psychiatric symptoms and memory disturbances. Dendritic spine dynamics have been discussed as a possible morphological correlate. However, the underlying mechanisms are still elusive. 3,4-Methylenedioxyamphetamine (MDA), a major drug of abuse and a main metabolite after 3,4-methylenedioxymethamp
