However, the foundations of intraventricular blood washout and its exposure to shear stresses have been poorly addressed. We aimed to characterize and quantify these features in a wide population of healthy subjects and assess the ...

Leptomeningeal anastomoses or pial collateral vessels play a critical role in cerebral blood flow (CBF) restoration following ischemic stroke. The magnitude of this adaptive response is postulated to be controlled by the endothelium, although the underlying molecular mechanisms remain under investigation. Here we demonstrated that endothelial genetic deletion, using EphA4fl/fl/Tie2-Cre and EphA4fl/fl/VeCahderin-CreERT2 mice and vessel painting strategies, implicated EphA4 receptor tyrosine kinase as a major suppressor of pial collateral remodeling, CBF, and functional recovery following permanent middle cerebral artery occ...

Additionally, hydrothermal synthesis is a common method to control nanostructures. In practice, researchers paid more attention to the direct effect of “useful ions” on morphology or size of nanostructures, e.g. the combination and decomposition processes of H+ and WO42− to form WO3. Unfortunately, the effects of ot...

However, at room temperature they possess a B2-ordered crystal structure and, therefore, exhibit reduced ductility. Guided by thermodynamic calculations, the Al concentration was systematically reduced in MoCrTi-xAl (x&n...

Authors: Monte A, Nardello F, Pavei G, Moro S, Festa L, Tarperi C, Schena F, Zamparo P Abstract BACKGROUND: The aim of this study was to determine the influence of spring mass model characteristics (e.g. stiffness) and Achilles tendon proprieties in determining the energy cost of running in half marathon runners. METHODS: Achilles tendon characteristics (i.e. cross sectional area -ATCSA- and resting length - ATL-) were measured on 32 males by means of an ultrasound apparatus the day before a half marathon race. After these measurements the energy cost of running (C) was determined while the subjects run on a tr...
