The LiNbV(PO4)3 phosphate with the anti-NASICON structure (a = 12.126(1) Å, b = 8.6158(4) Å, c = 8.6959(6) Å, V = 908.5(1) Å3, S.G. Pbcn) has been synthesized using a Pechini sol–gel process. It exhibits reversible multielectron transitions versus Li and Na anodes. In a Li half-cell, it supports a 4e− transfer due to the activation of the Nb5+/Nb3+ and V4+/V2+ redox couples, being the first example of 4d metal redox transitions within the anti-NASICON framework confirmed by XANES measurements. X-ray diffraction performed in ex situ and operando regimes disclosed a single-phase mechanism of lithium (de)intercalation. In a Na half-cell, the material demonstrates reversible uptake of 2.77 Na+ ions. Density functional theory calculations revealed percolation barriers of ∼0.5–0.7 eV for Na+ hopping, thus supporting the activation of Na+ ion diffusion in the NbV(PO4)3 framework. This study introduces a new approach to improve anti-NASICON-structured electrode materials by utilizing redox transitions of 4d elements for energy storage. [ABSTRACT FROM AUTHOR]

Abstract: This paper presents a speckle-displacement measurement technique based on the digital image correlation to study the notch sensitivity and crack bridging of window security film. It is used to protect existing glazing against hurricanes, blast and terrorist explosions. The window security film is laminated to the interior side of the glass window by means of a special adhesive. When the glass is breaking, the window film keeps all glass fragments together. The proposed sub-pixel registration of the displacement field is achieved using a calculation technique based on the centre of mass localization of the complex spectrum. This approach increases the computational efficiency for displacements smaller than one pixel and performs with high precision when optimal values of the input correlation parameters are used. In order to achieve a high accuracy of the algorithm, optimization of these input image correlation parameters is offered. For larger displacements an iterative procedure which preserves the precision is successfully implemented. The speckle pattern is created by small white dots sprayed on the previously black painted film surface. As a result, white light illumination can be used which significantly simplifies the experiments. [Copyright &y& Elsevier]

Simple Summary: One of the most complicated problems during rectal cancer surgery is to determine what part of intestine to remove along with tumor. If the excised fragment will be too small, it could increase the risk of tumor recurrence. On the contrary, the removal of extra tissues could be completely unnecessary and complicate patient life a lot, especially when the region is close to sphincter. To determine the length of fragments to remove, it was necessary to reveal areas without changes in molecule functioning, specific for tumor. We investigated functioning the proteasomes, important cellular components, in patient rectal cancer and different intestine locations and did not reveal tumor-specific characteristics of proteasomes at sphincter side of intestine even at a distance of 2–4 cm from the tumor. This result supports the idea of preserving the sphincter under surgery. Besides, we discovered proteasome subtype that may be a promising target for anti-cancer therapy. A special problem in the surgery of rectal cancer is connected with a need for appropriate removal of intestine parts, along with the tumor, including the fragment close to the sphincter. To determine the length of fragments to remove, it is necessary to reveal areas without changes in molecule functioning, specific for tumor. The purpose of the present study was to investigate functioning the proteasomes, the main actors in protein hydrolysis, in patient rectal adenocarcinoma and different intestine locations. Chymotrypsin-like and caspase-like activities, open to complex influence of different factors, were analyzed in 43–54 samples by Suc-LLVY-AMC- and Z-LLE-AMC-hydrolysis correspondingly. Both activities may be arranged by the decrease in the location row: cancer→adjacent tissue→proximal (8–20 cm from tumor) and distal (2 and 4 cm from tumor) sides. These activities did not differ noticeably in proximal and distal locations. Similar patterns were detected for the activities and expression of immune subunits LMP2 and LMP7 and expression of 19S and PA28αβ activators. The largest changes in tumor were related to proteasome subtype containing LMP2 and PA28αβ that was demonstrated by native electrophoresis. Thus, the results indicate a significance of subtype LMP2-PA28αβ for tumor and absence of changes in proteasome pool in distal fragments of 2–4 cm from tumor. [ABSTRACT FROM AUTHOR]

Platelets play a pivotal role in the pathophysiology of the acute coronary syndromes, and platelet inhibition is a cornerstone in the management of these patients. Patients with profound thrombocytopenia who present with an acute coronary syndrome present a difficult challenge. The authors report a patient with immune thrombocytopenic purpura who presented with acute myocardial infarction despite a very low platelet count and who sustained recurrent infarction after receiving immune globulin treatment. The best management of thrombocytopenic patients with acute coronary syndromes is uncertain, but extreme caution is needed before efforts are made to raise the platelet count in order to allow conventional treatment.
