Mechanistic Insights in the Mode of Action of Bifunctional Pyrrolidine-Squaramide-derived Organocatalysts
(Wiley-VCH, 2016)
The modes of catalytic action of three squaramide-derived
bifunctional organocatalysts have been investigated using DFT
methods. The [5+2] cycloaddition between oxidopyrilium ylides and
enals has been used as model ...
Snail heterogeneity in clear cell renal cell carcinoma
(Biomed Central, 2016-03-08)
Background: Intratumor heterogeneity may be responsible of the unpredictable aggressive clinical behavior that some clear cell renal cell carcinomas display. This clinical uncertainty may be caused by insufficient sampling, ...
Expression and Localization of Opioid Receptors in Male Germ Cells and the Implication for Mouse Spermatogenesis
(Public Library Science, 2016-03-31)
The presence of endogenous opioid peptides in different testicular cell types has been extensively characterized and provides evidence for the participation of the opioid system in the regulation of testicular function. ...
Streptococcus pyogenes Pneumonia in Adults: Clinical Presentation and Molecular Characterization of Isolates 2006-2015
(Public Library Science, 2016-03-30)
Introduction
In the preantibiotic era Streptococcus pyogenes was a common cause of severe pneumonia but currently, except for postinfluenza complications, it is not considered a common cause of community-acquired pneumonia ...
Low‑cost origami fabrication of 3D self‑aligned hybrid microfluidic structures
(Springer, 2016-08)
[EN] 3D microfluidic device fabrication methods are normally quite expensive and tedious. In this paper, we present an easy and cheap alternative wherein thin cyclic olefin polymer (COP) sheets and pressure sensitive ...
Identification of Sex and Female’s Reproductive Stage in Commercial Fish Species through the Quantification of Ribosomal Transcripts in Gonads
(Public Library Science, 2016-02-26)
The estimation of maturity and sex of fish stocks in European waters is a requirement of the EU Data Collection Framework as part of the policy to improve fisheries management. On the other hand, research on fish biology ...
Number of Players and Relative Pitch Area per Player: Comparing Their Influence on Heart Rate and Physical Demands in Under-12 and Under-13 Football Players
(Public Library Science, 2016-01-11)
The aim of the present study is to analyse the influence of different large-sided games (LSGs) on the physical and physiological variables in under-12s (U12) and -13s (U13) soccer players. The effects of the combination ...
Feedback on the Rate and Depth of Chest Compressions during Cardiopulmonary Resuscitation Using Only Accelerometers
(Public Library Science, 2016-03-01)
Background
Quality of cardiopulmonary resuscitation (CPR) is key to increase survival from cardiac arrest. Providing chest compressions with adequate rate and depth is difficult even for well-trained rescuers. The use ...
Eurobalise-Train communication modelling to assess interferences in railway control signalling systems
(Macrothink Institute, 2016-05-10)
The evolution of the railway sector depends, to a great extent, on the deployment of advanced railway signalling systems. These signalling systems are based on communication architectures that must cope with complex ...
Biomass Pyrolysis Solids as Reducing Agents: Comparison with Commercial Reducing Agents
(MDPI, 2016-01)
Biomass is one of the most suitable options to be used as renewable energy source due to its extensive availability and its contribution to reduce greenhouse gas emissions. Pyrolysis of lignocellulosic biomass under ...
