Structural synaptic reorganizations needed to permanently embed novel memories in the brain involve complex plasticity-enhancing and plasticity-inhibiting systems. Increased neural activity is linked to rapid downregulation of Nogo receptor 1 (NgR1), needed to allow local structural synaptic plasticity. This local regulation of plasticity is thought to be moderated by global systems, such as the ascending cholinergic and monoaminergic systems, adding significance to locally increased neural activity. Here we address the reverse possibility that the global systems may also be influenced by the status of local plasticity. Using NgR1-overexpressing mice, with impaired plasticity and long-term memory, we measured the ability to release dopamine (DA), implicated in regulating plasticity and memory. In vivo chronoamperometric recording with high temporal and spatial resolution revealed severe impairment of potassium chloride (KCI)-induced increase of extracellular DA in the dorsal striatum of mice overexpressing NgR1 in forebrain neurons. A similar, but lesser, impairment of DA release was seen following amphetamine delivery. In contrast, potassium chloride-evoked DA release in NgR1 knockout (KO) mice led to increased levels of extracellular DA. That NgR1 can impair DA signaling, thereby further dampening synaptic plasticity, suggests a new role for NgR1 signaling, acting in synergy with DA signaling to control synaptic plasticity. Significance Statement: The inverse correlation between local NgR1 levels and magnitude of KCl-inducible amounts of DA release in the striatum reinforces the rule of NgR1 as a regulator of structural synaptic plasticity and suggests synergy between local and global plasticity regulating systems.

#REF!

High-stability, zirconium-based metal-organic frameworks are attractive as heterogeneous catalysts and as model supports for uniform arrays of subsequently constructed heterogeneous catalysts-for example, MOF-node-grafted metal-oxy and metal-sulfur clusters. For hexa-Zr(IV)-MOFs characterized by nodes that are less than 12-connected, sites not used for linkers are ideally occupied by reactive and displaceable OH/H2O pairs. The desired pairs are ideal for grafting the aforementioned catalytic clusters, while aqua-ligand lability renders them effective for exposing highly Lewis-acidic Zr(IV) sites (catalytic sites) to candidate reactants. New single-crystal X-ray studies of an eight-connected Zr-MOF, NU-1000, reveal that conventional activation fully removes modulator ligands, but replaces them with three node-blocking formate ligands (from solvent decomposition) and only one OH/H2O pair, not four-a largely overlooked complication that now appears to be general for Zr-MOFs. Here we describe an alternative activation protocol that effectively removes modulators, avoids formate, and installs the full complement of terminal OH/H2O pairs. It does so via an unusual isolatable intermediate featuring eight aqua ligands and four non-ligated chlorides-again as supported by single-crystal X-ray data. We find that complete replacement of node-blocking modulators/formate with the originally envisioned OH/OH2 pairs has striking consequences; here we touch upon just three. First, elimination of unrecognized formate renders aqua ligands much more thermally labile, enabling open Zr(IV) sites to be obtained at lower temperature. Second, in the absence of formate, which otherwise links and locks pairs of node Zr(IV) ions, reversible removal of aqua ligands engenders reversible contraction of MOF meso- and micropores, as evidenced by X-ray diffraction. Third, formate replacement with OH/OH2 pairs renders NU-1000 ca.10X more active for catalytic hydrolytic degradation of a representative simulant of G- type chemical warfare agents.

In this work, the recycled acrylonitrile-butadiene-styrene (rABS)/anhydrous zinc chloride (ZnCl2) composites were prepared and the reinforcing effects of the rABS/ZnCl2 composites were investigated using various characterization techniques. During heat pressing at 190 degrees C, a strong coordination interaction occurred between Zn2+ of ZnCl2 particles and -CN groups of rABS matrix, which resulting in an enhancement of mechanical and thermal properties in comparison with the neat rABS. Fourier transform infrared spectroscopy, dissolution experiments, ultraviolet-visible spectroscopy, and X-ray photoelectron spectroscopy were applied to prove the coordination reaction. Scanning electron microscopy showed ZnCl2 particles were homogeneously dispersed in the rABS matrix. Tensile test analysis showed that the flexural strength and tensile strength of rABS/ZnCl2 composites increased by around 12.07% and 18.17%, respectively, when adding 7 phr of ZnCl2 into the rABS resin. Furthermore, heat deflection temperature analysis, thermogravimetric analysis as well as dynamic mechanical analysis proved that the coordination reaction dramatically improved the heat resistance of rABS matrix. Besides, the recycling ability of the composites had also been proved.

Pathological thrombosis within a vessel hampers blood flow and is the mainspring of numerous fatal cardiovascular complications. In order to specifically image and dissolve a thrombus, we rationally designed a functionalized polymeric hybrid micelle (PHM) system self-assembled from amphiphilic polycaprolactone-polyethylenimine (PCL-PEI) and polycaprolactone-polyethylene glycol (PCL-PEG). Based on a biological component of thrombi, activated coagulation factor XIII (FXIIIa), which is responsible for fibrin crosslinking, we further developed FXIIIa-targeted near infrared imaging and thrombolytic nanoparticles, termed IR780/FPHM/LK NPs, through chemical conjugation of peptides to the system. In a ferric chloride (FeCl3)-induced mouse carotid thrombosis model, IR780/FPHM/LK NPs specifically targeted the thrombus and significantly enhanced the photoacoustic signal for an accurate diagnosis. When loaded with the fibrinolytic drug lumbrokinase (LK), FPHM remarkably dissociated the thrombus accompanied by an increase in the D-dimer level, a fibrin degradation product, and alleviation of fatal nonspecific hemorrhagic risk. Given its thrombus-specific imaging along with potent therapeutic activities, IR780/FPHM/LK NPs hold promise for developing nanotheranostic agents in preclinical thrombotic vascular disease models. Statement of significance In this study, we developed a functionalized polymeric hybrid micelle system self assembled from amphiphilic copolymers, polycaprolactone-polyethylenimine (PCL-PEI) and polycaprolactone-polyethyleneglycol (PCL-PEG). The conjugation of FXIII peptide could facilitate the specific delivery of the system to the FXIIIa-rich thrombosis site. In a FeCl3-induced mouse arterial thrombosis model, the system could specifically image thrombosed vessels and exert significant thrombolytic effect without affecting normal hemostatic function, through the delivery of near-infrared imaging probe and fibrinolytic drug simultaneously. Therefore, this system has great potential for high-performance delivery of proteinase and near-infrared probe to thrombosis site, achieving diagnosis and treatment of arterial thrombosis disease.(C) 2020 Acta Materialia Inc.

Application of recycled aggregate concrete (RAC) in engineering practice today remains relatively limited. One of the main reasons may be that the material’s durability has not been comprehensively understood. No sufficiently accurate formulas are available for predicting its resistance to chloride infiltration. This study was therefore designed to investigate the commonest factors influencing chloride penetration in RAC using mesoscale finite element models. The variables of interest were the geometric shape of coarse aggregate pieces, their location distribution, the volume content of recycled material, the relative strength of the old to new mortar, the adhering content of old mortar, the bonding property of interfacial transition zones (ITZs) and the mixing method used. After performing a series of numerical simulations, a genetic programming (GP) method was lastly adopted to establish an explicit expression for correlating the RAC’s effective chloride diffusivity with the identified key factors. Numerical results indicate that the RAC’s diffusion coefficient was negligibly influenced by the aggregate shape or the old ITZ property, and commonly grows with increasing water-to-cement ratio, the amount of old mortar, the new ITZ’s diffusivity as well with the replacing content of recycled aggregates. Equivalent mortar volume method can efficiently decrease the material’s chloride diffusivity, especially at low water-to-cement ratios in the attached mortar. Finally, the expression provided by the GP method can adequately predict all these trends and is very convenient for investigating the RAC’s chloride diffusion performance. (C) 2020 Elsevier Ltd.

Developing one-step modification strategy for highly efficient metal-free g-C3N4 photocatalyst has always been challenging and yet demanding. In this study, we have demonstrated an in-situ low-temperature production of porous S-doped g-C3N4 nanosheets, using ammonium chloride (NH4Cl) as a gaseous-bubble template (GBT) to boost the visible-light photocatalytic degradation of organic pollutant dyes. The photocatalytic activities of GBT-induced porous S-doped g-C3N4 nanosheets (so-called p-SCN-x, x = mass ratio of NH4Cl/thiourea) were examined towards the degradation of Rhodamine B (Rh.B) under visible light. Importantly, both surface area and photocatalytic activities of the p-SCN-xsample were optimized by adjusting the mass fraction of thiourea/NH4Cl. The optimized p-SCN-2 exhibited a maximum photocatalytic degradation of 97.50%, which is 7.75-fold higher than that of GBT-free analogue (so-called bulk SCN-O). Moreover, the p-SCN-2 was tested for colorless tetracycline hydrochloride as an emerging pollutant, demonstrating 87% degradation under visible light irradiation. The enhanced performance of p-SCN-2photocatalyst was mainly attributed to an improved surface area, boosted light-harvesting range, and efficient electron-hole separation, and facilitated transfer of charge carriers by dyesensitization mechanism. Moreover, the scavengers quenching study proved that the superoxide anion (O-center dot(2)-) radicals and holes (h(+)) were the leading active sorts. In situ fabrication of p-SCN-x nanosheets at low temperature provided an inexpensive and green synthetic route for highly active g-C3N4-based photocatalysts that can resolve environmental pollution and clean energy issues.

Proton-dependent inhibition, inverted voltage activation, and slow gating of CLC-0 Chloride Channel

CLC-0, a prototype Cl- channel in the CLC family, employs two gating mechanisms that control its ion-permeation pore: fast gating and slow gating. The negatively-charged sidechain of a pore glutamate residue, E166, is known to be the fast gate, and the swinging of this sidechain opens or closes the pore of CLC-0 on the millisecond time scale. The other gating mechanism, slow gating, operates with much slower kinetics in the range of seconds to tens or even hundreds of seconds, and it is thought to involve still-unknown conformational rearrangements. Here, we find that low intracellular pH (pH(i)) facilitates the closure of the CLC-0’s slow gate, thus generating current inhibition. The rate of low pH(i)-induced current inhibition increases with intracellular H+ concentration ([H+](i))-the time constants of current inhibition by low pH(i) = 4.5, 5.5 and 6 are roughly 0.1, 1 and 10 sec, respectively, at room temperature. In comparison, the time constant of the slow gate closure at pH(i) = 7.4 at room temperature is hundreds of seconds. The inhibition by low pH(i) is significantly less prominent in mutants favoring the slow-gate open state (such as C212S and Y512A), further supporting the fact that intracellular H+ enhances the slow-gate closure in CLC-0. A fast inhibition by low pH(i) causes an apparent inverted voltage-dependent activation in the wild-type CLC-0, a behavior similar to those in some channel mutants such as V490W in which only membrane hyperpolarization can open the channel. Interestingly, when V490W mutation is constructed in the background of C212S or Y512A mutation, the inverted voltage-dependent activation disappears. We propose that the slow kinetics of CLC-0’s slow-gate closure may be due to low [H+](i) rather than due to the proposed large conformational change of the channel protein. Our results also suggest that the inverted voltage-dependent opening observed in some mutant channels may result from fast closure of the slow gate by the mutations.
