Knowledge of bisphosphonate-related osteonecrosis of the jaw (BRONJ) is mostly based on adult cases, however bisphosphonates are also currently recommended for different paediatric diseases resulting in osteoporosis. The aim of this study was to review the literature on the risk of developing BRONJ in children and adolescents. The PubMed, LILACS, Web of Science, Scopus, and Cochrane databases were searched using the key words “bisphosphonates”, “osteonecrosis”, “jaw”, and “children”. Literature reviews,...

The objective was to introduce a new technique for visualizing the three-dimensional (3D) movements of velopharyngeal-related muscles using high-speed cine-magnetic resonance imaging (MRI) based on T2-weighted sequences. The evaluation of phonation- and water swallowing-related events was performed in 11 healthy subjects. Specifically, whether cine-MRI could precisely visualize normal velopharyngeal function during these two events was examined. The 3D movements of the soft palate, superior pharyngeal...

Publication date: Available online 26 August 2019Source: Aggression and Violent BehaviorAuthor(s): Tony WardAbstractEffective and ethical psychological practice relies on good science, and good science takes theory construction very seriously, as seriously as data collection. There is little point in developing valid research designs and sophisticated data analytic techniques if the ideas driving research are mistaken or trivial. In this paper I explore the problem of theoretical illiteracy for correctional...

When treating anaphylaxis, epinephrine is generally given via an intramuscular (IM) route. This is well established to be effective and life-saving. One advantage of IM administration is immediate use (without requiring intravenous access), including by patient auto-injection. IM epinephrine is doubtless the best approach for patient self-treatment, for first responders, and for immediate treatment in […] EMCrit Project by Josh Farkas.

Abstract Interface modification is an effective strategy to improve the performance of perovskite solar cells (PSCs). In this work, edible materials like glycerol and choline chloride were used to modify the surface of hole transport layer (HTL) NiOx. CH3NH3PbI3 (MAPbI3) film fabricated on the modified NiOx has a smoother surface and more uniform grains. It enables an improvement in short-circuit current density (JSC) of PSC from 17.77 ± 0.18 to 20.35 ± 0.36 mA cm−2, leading...

Abstract We apply an alloying strategy to single-layer PtN2 and PtP2, aiming to obtain a single-layer Pt–P–N alloy with a relatively low formation energy with reference to its bulk structure. We perform structure search based on a cluster-expansion method and predict single-layer and bulk PtPN consisting of pentagonal networks. The formation energy of single-layer PtPN is significantly lower in comparison with that of single-layer PtP2. The predicted bulk structure of PtPN adopts...

Abstract A controlled acidic precipitation is reported for the direct synthesis of nanosheets self-assembled hierarchical tungstic acid microspheres, and their annealing-dependent thermal conversion into WO3 microstructures is studied for the first time. The synthesis was carried out without the use of any structure directing agents and hydrothermal conditions. The microspheres were found to be consisting of many single-crystalline and highly oriented nanosheets that were hierarchically...

Abstract To address the need for production of a large number of microspheres for use in various fields such as tissue engineering, we developed a 3D coaxial multi-nozzle flow focusing device fabricated via a simple 3D printing method that demonstrates a high rate of microsphere production per nozzle. This device has six coaxial microscale nozzles that produce hydrogel microspheres. Two individual parts—the inlet and nozzle—can be made separately by a 3D printer and bonded together...

Abstract To study the formation mechanism of a conductive layer in a laser-processed AlN ceramic plate, nanosecond laser treatment on an AlN ceramic was performed to generate an Al layer, which created conductivity on the surface. Changes in the resistance for different energy densities, pulse durations, line spacings and scanning speeds were studied by means of XPS and scanning electron microscopy. The results show that the resistance is inversely proportional to the duration...

Abstract Fuel cells capable of synthetic glucose catalysis have revolved around the implementation of abiotic catalysts that require extreme acid and alkaline environments. These are not compatible with implantable medical sensor systems, and hence, there is a need to develop abiotic catalysts that operate at neutral pH. This paper presents structural and electrochemical characteristics of a nanoporous electrode designed for abiotic glucose oxidation in the presence of oxygen...

Abstract A series of FeNi–MgO nanogranular soft magnetic films with different sputtering powers of MgO were deposited by co-sputtering at room temperature on naturally oxidized silicon substrates. By adjusting the sputtering power of MgO, the average grain size of FeNi–MgO granular film reduces from 6.5 to 4 nm. The easy-axis coercivity Hce decreases from 8 to 0.3 Oe and saturation field Hs decreases from 14 to 1 Oe. When the sputtering power of MgO is above 60 W, Hce and Hs...

Abstract For the first time, a porous CoSe2/C microsphere interwoven by ultrathin CoSe2 and carbon nanosheets is synthesized by a simple solvothermal method. Compared with bare CoSe2, the CoSe2/C hybrid exhibits much better performance for hydrogen evolution reaction (HER): The hybrid demonstrates a Tafel mechanism rather than the Heyrovsky mechanism of CoSe2; it has a low onset potential (− 189 mV vs RHE) and an ultra-low Tafel slope (34 mV dec−1); current density increases...
