The neutrophil-recruiting chemokine GCP-2/CXCL6 is expressed in cystic fibrosis airways and retains its functional properties after binding to extracellular DNA.

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 promote bacterial dissemination in a mouse model of streptococcal sepsis.

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

Blockade of CD27/CD70 pathway to reduce the generation of memory T cells and markedly prolong the survival of heart allografts in presensitized mice

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

Conditional Cash Transfers and Social Mobility: The Role of Asymmetric Structures and Segmentation Processes

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

Pancreaticoduodenectomy - the transition from a low- to a high-volume center.

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

A general criterion for evaporative heat transfer in micro/mini-channels

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

Change in quality of life of people with dementia recently admitted to long-term care facilities

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 of Ga(III) and EDTA at the Water-alpha-FeOOH Interface: Spectroscopic Evidence of the Formation of Ternary Surface Complexes

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

Debt Relief, Investment and Growth

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

Randomized, Multicenter, Phase II Study of CO-101 Versus Gemcitabine in Patients With Metastatic Pancreatic Ductal Adenocarcinoma: Including a Prospective Evaluation of the Role of hENT1 in Gemcitabine or CO-101 Sensitivity.

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

Acoustofluidics 11: Affinity specific extraction and sample decomplexing using continuous flow acoustophoresis.

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

Effect of 3,4-Methylenedioxyamphetamine on Dendritic Spines Dynamics in Rat Neocortical Neurons - Involvement of Heat Shock Protein 27.

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

Impact of professionalism in nursing on in-hospital bedside monitoring practice.

AIM: This article reports a study exploring nursing practice of monitoring in-hospital patients including intra- and interprofessional communication and collaboration. BACKGROUND: Sub-optimal care in general in-hospital wards may lead to admission for intensive care, cardiac arrest, or sudden death. Reasons may include infrequent measurements of vital parameters, insufficient knowledge of thei

The problem of confounding in studies of the effect of maternal drug use on pregnancy outcome.

In most epidemilogical studies, the problem of confounding adds to the uncertainty in conclusions drawn. This is also true for studies on the effect of maternal drug use on birth defect risks. This paper describes various types of such confounders and discusses methods to identify and adjust for them. Such confounders can be found in maternal characteristics like age, parity, smoking, use of alcoh
