Cardiac fibroblasts (CFs) play a key role in response to injury and remodeling of the heart. Nucleotide (P2) receptors regulate the heart but limited information is available regarding such receptors in CFs. We thus sought to determine if extracellular nucleotides regulate fibrotic responses (e.g., proliferation, migration and expression of profibrotic markers) of CFs in primary culture. UTP incre

BACKGROUND: Mild hypothermia is currently standard of care for cardiac arrest patients in many hospitals and a common belief is that hypothermia attenuates platelet aggregation. We wanted to examine the effects of clopidogrel on platelet aggregation during hypothermia.METHODS: Platelet reactivity at 37° C and 33° C was evaluated by light transmission aggregometry and vasodilator-stimulated phospho

Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and thermal stability. Studies o

Aim To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4 months of life. Methods Full-term infants (n = 382) were randomised to delayed (≥180 sec) or early cord clamping (≤10 sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4 months. Immunoglobulin G

We describe three cases of community-acquired pneumonia, in which the causative agent was methicillin sensitive S. Aureus positive for Panton-Valentine leukocidin (PVL). The patients were previously healthy children (2 weeks, 12 years and 15 years old). No epidemiologic connection existed, confirmed by spa-typing. Two cases were primary pneumonias with signs of necrosis, and the third case was a p

Rheumatoid arthritis-associated joint pain is frequently observed independent of disease activity, suggesting unidentified pain mechanisms. We demonstrate that antibodies binding to cartilage, specific for collagen type II (CII) or cartilage oligomeric matrix protein (COMP), elicit mechanical hypersensitivity in mice, uncoupled from visual, histological and molecular indications of inflammation. C

Background: The aim of this study was to determine whether lymph node metastasis on pre-treatment 18F-choline PET/CT is an independent prognostic factor for biochemical recurrence (BCR), skeletal metastasis, and cancer specific mortality (CSM), after radical local treatment (radical prostatectomy and/or radiotherapy) in men with high-risk prostate cancer. Medical records were reviewed for men with

The stiffness assessment of the trackbed should include an assessment of ballast, subballast and formation (e.g sub-ballast depth, groundwater profile). Furthermore, a lack of a systematic monitoring brings to the impossibility to produce an effective long term track management system, by allocating budget where emergencies come. Consequently, there is an increasing importance in obtaining a consi

Railway tracks are complex systems, made up numerous critical components such as rails, sleepers/ties, fasteners, ballast, joints, crossings, switches, that require regular monitoring in order to ensure track safety and optimize track efficiency. Many large railways make use of expensive Track Geometry Cars in order to measure railway asset condition through the measurement of rail geometry (gauge

The present paper reports different applications which have a common data source: Automatic Road Analyzer (ARAN) of the Transport Infrastructure Laboratory of the University of Catania. Data surveyed with ARAN were used to develop performance indicators of the road asset. A BIM model makes possible to improve the flexibility in information access and to merge data with the aim to allow a complete

Safety performance functions (SPFs) are crucial to science-based road safety management. Success in developing and applying SPFs, apart data quality and availability, depends fundamentally on two key factors: the validity of the statistical inferences for the available data and on how well the data can be organized into distinct homogeneous entities. The latter aspect plays a key role in the ident
