Compared to skin, wound healing in oral mucosa is faster and produces less scarring, but the mechanisms involved are incompletely understood. Studies in mice have linked high expression of CD26 to a profibrotic fibroblast phenotype, but this has not been tested in models more relevant for humans. We hypothesized that CD26 is highly expressed by human skin fibroblasts (SFBLs), and this associates with a profibrotic phenotype distinct from gingival fibroblasts (GFBLs). We compared CD26 expression in human gingiva and skin and in gingival and hypertrophic-like scar-forming skin wound healing in a pig model, and used three-dimensional cultures of human GFBLs and SFBLs...

The energy density of rechargeable batteries utilizing metals as anodes surpasses Li-ion batteries, which employ carbon instead. Among possible metals, magnesium represents a potential alternative to the conventional choice, lithium, in terms of storage density, safety, stability, and cost. However, a major obstacle for metal-based batteries is the identification of electrolytes that show reversible deposition/dissolution of the metal anode and support reversible intercalation of ions into a cathode. Traditional Grignard-based Mg electrolytes are excellent toward reversible deposition of Mg, but their limited anodic stability and compatibility with oxide cathodes hinder their applicability in Mg batteries with higher voltage...

The realization of antipulverization electrode structures, especially using low-carbon-content anode materials, is crucial for developing high-energy and long-life lithium-ion batteries (LIBs); however, this technology remains challenging. This study shows that SnO2 triple-shelled hollow superstructures (TSHSs) with a low carbon content (4.83%) constructed by layer-by-layer assembly of various nanostructure units can withstand a huge volume expansion of ≈231.8% and deliver a high reversible capacity of 1099 mAh g(-1) even after 1450 cycles...

Stacey L Peek, Kar Men Mah, Joshua A Weiner
The protocadherins (Pcdhs), which make up the most diverse group within the cadherin superfamily, were first discovered in the early 1990s. Data implicating the Pcdhs, including ~60 proteins encoded by the tandem Pcdha, Pcdhb, and Pcdhg gene clusters and another ~10 non-clustered Pcdhs, in the regulation of neural development have continually accumulated, with a significant expansion of the field over the past decade. Here, we review the many roles played by clustered and non-clustered Pcdhs in multiple steps important for the formation and function of neural circuits, including dendrite arborization, axon outgrowth and targeting, synaptogenesis, and synapse elimination...

The aim of this study was to compare the accuracy of six intraoral scanners as regards clinically relevant distances using a new method of evaluation. An additional objective was to compare intraoral scanners with the indirect digitization of model scanners. A resin master model was created by 3D printing and drilled in five places to reflect the following distances: intermolar width (IMW), intercanine width (ICW), and arch length (AL). To determine a gold standard, the distances were measured with a coordinate measuring instrument (Zeiss O-Inspect 422)...

Adamantyl-based compounds are clinically important for the treatments of type 2 diabetes and for their antiviral abilities, while many more are under development for other pharmaceutical uses. This study focused on the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of adamantyl-based ester derivatives with various substituents on the phenyl ring using Ellman's colorimetric method. Compound 2e with a 2,4-dichloro electron-withdrawing substituent on the phenyl ring exhibited the strongest inhibition effect against AChE, with an IC50 value of 77...

A study was performed to evaluate the effect of thermal hydrolysis pretreatment (THP) temperature on subsequent digestion performance and operation, as well as downstream parameters such as dewatering and cake quality. A blend of primary and secondary solids from the Blue Plains treatment plant in Washington, DC was dewatered to about 16% total solids (TS), and thermally hydrolyzed at five different temperatures 130, 140, 150, 160, 170 °C. The thermally hydrolyzed solids were then fed to five separate, 10 L laboratory digesters using the same feed concentration, 10...

Sodium-ion batteries are potential low-cost alternatives to current lithium-ion technology, yet their performance still fall short of expectation due to the lack of suitable electrode materials with large capacity, long-term cycling stability and high-rate performance. In this work, we demonstrated that ultrasmall (~5 nm) iron selenide (FeSe2) nanoparticles exhibited a remarkable performance for sodium-ion storage. They were prepared from a high-temperature solution method with a narrow size distribution and high yield, and could be readily redispersed in non-polar organic solvents...

Aqueous rechargeable batteries provide the safety, robustness, affordability, and environmental friendliness necessary for grid storage and electric vehicle operations, but their adoption is plagued by poor cycle life due to the structural and chemical instability of the anode materials. Here we report quinones as stable anode materials by exploiting their structurally stable ion-coordination charge storage mechanism and chemical inertness towards aqueous electrolytes. Upon rational selection/design of quinone structures, we demonstrate three systems that coupled with industrially established cathodes and electrolytes exhibit long cycle life (up to 3,000 cycles/3,500 h), fast kinetics (≥20C), high anode specific capacity (up to 200-395 mAh g(-1)), and several examples of state-of-the-art specific energy/energy density (up to 76-92 Wh kg(-1)/ 161-208 Wh l(-1)) for several operational pH values (-1 to 15), charge carrier species (H(+), Li(+), Na(+), K(+), Mg(2+)), temperature (-35 to 25 °C), and atmosphere (with/without O2), making them a universal anode approach for any aqueous battery technology...

We report a highly performing anode material for sodium-ion batteries (SIBs), composed of graphene decorated indium sulfide (In2S3). The composite material is synthesized by adopting a facile hydrothermal pathway with subsequent annealing, and characterized by defined structure and well-tailored morphology, as indeed demonstrated by X-ray diffraction, spectroscopy as well as high resolution microscopy. These optimal characteristics allow the electrode to perform remarkably in sodium cell by achieving a maximum specific capacity as high as 620 mAh g-1, and the still relevant value of 335 mAh g-1 at an extremely high current (i...

Mg-Li hybrid batteries have attracted wide interest in recent years because of the potential safety as well as the cost benefit and high volumetric capacity. However, the slow kinetic properties strongly hinder their commercial application. In this study, we prepare spinel LiCrTiO4 by the solid-state reaction and conduct a comprehensive study on the improvement of its performance in Mg-Li hybrid batteries by optimizing the dual-salt electrolytes. It is found that LiCrTiO4 shows the reversible discharge/charge capacity of 178/169 mAh g-1 in the electrolyte of 1 M LiCl and 0...

A Cr(3+) and F(-) composite-doped LiNi0.5Mn1.5O4 cathode material was synthesized by the solid-state method, and the influence of the doping amount on the material's physical and electrochemical properties was investigated. The structure and morphology of the cathode material were characterized by XRD, SEM, TEM, and HRTEM, and the results revealed that the sample exhibited clear spinel features. No Cr(3+) and F(-) impurity phases were found, and the spinel structure became more stable. The results of the charge/discharge tests, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) test results suggested that LiCr0...

Radiochromic film for spot-scanning QA provides high spatial resolution and efficiency gains from one-shot irradiation for multiple depths. However, calibration can be a tedious procedure which may limit widespread use. Moreover, since there may be an energy dependence, which manifests as a depth dependence, this may require additional measurements for each patient. We present a one-scan protocol to simplify the procedure. A calibration using an EBT3 film, exposed by a 6-level step-wedge plan on a Proteus(®)PLUS proton system (IBA, Belgium), was performed at depths of 18, 20, 24cm using Plastic Water(®) (CIRS, Norfolk, VA)...

Recent assignment of some goniasterid-like Ophidiasteridae into the Goniasteridae has led to further re-evaluation of other ophidiasterids as possible goniasterids. This led to the discovery of new genera and species supported by a distinctive set of characteristics which support a new subfamily, the Ferdininae, a group originally outlined by Marsh and Price (1991) within the Goniasteridae. The historical Ophidiasteridae is paraphyletic and includes several nominal ophidiasterid genera (e.g., Fromia, Neoferdina, etc...

A new type of Li-Cu composite powder electrode (Li-Cu CE) was fabricated via mechanical blending of Li and Cu powders. The new Li-Cu electrode is capable of replacing Li metal anodes in Li metal secondary battery (LMSB) systems without exhibiting typical intrinsic problems such as dendrite growth, volume change, and electrolyte depletion. Thus, Li-Cu CE cells can offer longer lives and very high capacities. The Li particles in Li-Cu CEs are surrounded by Cu particles and thus cannot form networks that extend throughout the electrode...

By utilizing small sheets of graphene oxide, the partitioned-pomegranate-like structure was constructed (SnO2@C@half-rGO), in which the porous clusters of SnO2 nanoparticles are partially supported by reduced graphene oxide sheets while the rest part is exposed (half-supported), like partitioned pomegranates. When served as anode for lithium-ion batteries, SnO2@C@half-rGO exhibited considerably high specific capacity (1034...
