HDAC3 Downregulation Improves Cerebral Ischemic Injury via Regulation of the SDC1-Dependent JAK1/STAT3 Signaling Pathway Through miR-19a Upregulation

Histone deacetylase (HDAC) inhibitors can protect the brain from ischemic injury. This study aimed to identify the regulation of HDAC3 in cerebral ischemic injury. Middle cerebral artery occlusion (MCAO) was performed to establish a mouse model with cerebral ischemic injury, in which expression of HDAC3 and miR-19a was evaluated using RT-qPCR. In MCAO mice with silencing of HDAC3, infarct volume was determined using 2,3,5-triphenyl tetrazolium chloride (TTC) staining, and serum levels of TNF-alpha, IL-6, and IL-8 were measured using ELISA. An in vitro model was constructed in human umbilical vein endothelial cells (HUVECs) with oxygen-glucose deprivation/reoxygenation (OGD/R), followed by gain- and loss-of-function experiments. Relationships among miR-19a, HDAC3, and syndecan-1 (SDC1) were explored using RIP, ChIP, and dual-luciferase reporter assays. The expression of HDAC3, SDC1, JAK1, and STAT3 along with the extent of JAK1 and STAT3 phosphorylation was measured by Western blot analysis. HUVEC viability, apoptosis, and angiogenesis were assessed by CCK-8, flow cytometry, and angiogenesis assays in vitro separately. We found elevated HDAC3 and downregulated miR-19a expression in the MCAO mice. Decreased TNF-alpha, IL-6, and IL-8 serum levels were observed in response to silencing of HDAC3. HDAC3 inhibited the expression of miR-19a, which in turn targeted SDC1, leading to JAK1/STAT3 signaling pathway activation. HDAC3 overexpression or miR-19a inhibition repressed HUVEC viability and angiogenesis but enhanced HUVEC apoptosis. Our data unraveled the mechanism whereby HDAC3 inhibition ameliorated cerebral ischemic injury by activating the JAK1/STAT3 signaling pathway through miR-19a-mediated SDC1 inhibition.

A Promoted Mesoporous Silica-Based Material for SO2 Adsorption

Mesoporous materials have been widely used in the adsorption of air pollutants because of their uniform pore structure and large specific surface area. In this study, hexadecyltrimethylammonium chloride and tetramethylammonium hydroxide pentahydrate were used as structure-directing agents, silica as a silicon source, and tetramethylammonium silicate as a functional group to prepare a mesoporous silica-based material (MSBM) by a designed hydrothermal reaction. The synthetic materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunner-Emmet-Teller (BET), Fourier-transform infrared spectroscopy (FITR), and thermogravimetric analysis (TGA). The adsorption efficiency of MSBM for SO2 in simulated flue gas under different conditions was studied. The results showed that the structure of the MSBM was the hexagonally ordered MCM-41 structure. It had the characteristics of uniform appearance, large specific surface area, rich surface groups, and strong thermal stability. The static activity of SO2 in flue gas could reach 32.1 mg/g under optimal conditions, which was slightly inferior to activated carbon. Therefore, MSBM has great practical application potential in the treatment of SO2 in flue gas.

Embodied impacts of window systems: A comparative assessment of framing and glazing alternatives

The embodied impacts of window materials can be considered as hidden impacts. However, as buildings have become more energy efficient, the impacts of the windows are recognized as being increasingly significant and have not been thoroughly analyzed. Thus, comprehensive analysis should be performed to inform the wise selection of energy-efficient windows with lower embodied impacts. This article proposes an approach based on embodied impact assessment and Pareto optimal frontier to support environmentally friendly design of windows. A comprehensive assessment of the embodied environmental impacts of a standard size window was implemented for 32 alternative systems, considering four framing materials (aluminum, fiberglass, polyvinyl chloride, wood) and eight glazing solutions (for single-, double, tripled-glazed). Environmental impacts were calculated for non-renewable primary energy, global warming, acidification, eutrophication, and ozone layer depletion. Pareto optimal frontiers were identified, showing the trade-offs between environmental impacts and thermal transmittance (U-value). The components of the two main parts of a window (frame and glass) have been characterized to identify those that contribute most to the total embodied impacts. The results show that tempered or laminated glass and the glass coating (low-E film) increase the embodied impacts of glazing solutions. Of the framing materials, wood has the lowest embodied impacts in all categories, while aluminum has the highest impacts for the double and triple-glazed solutions. The breakdown of the embodied impacts of aluminum-framed window systems shows that the frame has higher impacts than the glazing, as it accounts for 60-80% of total embodied impacts. In the windows with polyvinyl chloride (PVC) and fiberglass frames, the frame is responsible for most of the embodied impacts for single-glazed windows (58-86%) and almost the same proportion for double-glazed windows (46-54%), but lower for triple-glazed (22-40%). The contribution of a wood frame (<30%) is much less significant. Pareto optimal frontiers are identified for the window systems and the non-dominated solutions are discussed for the various environmental impact categories. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Ammonium produced from Shewanella strain 0409 contributes to antiviral activity against Betanodavirus

Nervous necrosis virus (NNV) (genus: Betanodavirus) attacks aquacultured fish. Biocontrol may prevent and control the disease caused by NNV infection. Shewanella strain 0409 was isolated from the micmbiome of grouper intestines, and its culture supernatant (CS0409) could inhibit NNV replication in vitro. The present study elucidated the antiviral mechanism of Shewanella strain 0409 against NNV in vitro. In NNV-infected GF-1 cells, CS0409 reduced both NNV RNA synthesis and the percentage of cells expressing NNV RNA-dependent RNA polymerase (RdRp) within 24 hpi. However, NNV RdRp activity was not inhibited by CS0490 treatment. The most favorable time for CS0409 treatment in NNV-infected GF-1 cells was the period of viral adsorption, which revealed a high inhibition level of NNV RNA synthesis. Shewanella strain 0409 produced ammonium in CS0409. When ammonium in CS0409 was removed by heating with evaporation, the anti-NNV activity of CS0409 decreased. Moreover, ammonium in CS0409 inhibited the acidification of acidic organelles. Furthermore, the morphology of NNV virions changed to empty particles after exposure to pH 5 and 6, indicating that NNV uncoating required the acidic environment of endosomes. Therefore, ammonium in CS0409 is responsible for the anti-NNV activity in vitro by inhibiting the acidification of endosomes and then suppressing NNV uncoating.

Hydrophobic thermoplastic starch supramolecularly-induced by a functional sucrose based ionic liquid crystal

It is still a big challenge to obtain hydrophobic thermoplastic starch with outstanding mechanical performance due to the inevitable usage of typical hydrophilic plasticizers like glycerol during processing. Herein, we report a novel hydrophobic thermoplastic starch using a supramolecularly induced thermoplasticization technique. To achieve this aim, a functional sucrose-based ionic liquid crystal (ILC) including numerous chloride atoms has been firstly synthesized, and the obtained ILC molecules are then used as supramolecular inducers to thermoplasticize corn starch granules. Thermoplasticity and hydrophobicity of the prepared supramolecularly induced thermoplastic starch (STPS) with different ILC contents have been extensively investigated. Mechanism of the supramolecularly induced thermoplasticization has been investigated using molecular simulation as well. The prepared STPS with the maximum tensile strength of 8.4 MPa and water contact angle of about 117 degrees show large potential applications in green and sustainable packaging materials.

Characterization of surface films on constructional steel in carbonated media containing chloride and nitrite ions

The inhibition effect of NaNO2 on the electronic properties of the passive film was investigated for carbon steel exposed to solutions of pH=13 and pH= 9 keeping the ratio [inhibitor]/[chloride]=1. Cyclic voltammograms, polarization curves, electrochemical impedance spectroscopy, Mott-Schottky plots and Xray photoelectron spectra were analyzed. Steel is passive at pH=13 and active at pH=9 (carbonated solutions). Passivity can be regained in carbonated solutions when nitrite ions are also present. The thickness and composition of the surface films depend on alkalinity. Both films behave as n-type semiconductors. Donor density values are similar for films grown in solutions containing nitrite ions, regardless of the presence of carbonate ions and the difference in alkalinity. Nitrite ions inhibit pitting in both solutions, although the difference between pitting and open circuit potentials is 2.7 times higher at pH=13. Donor density values cannot be used as the single parameter to evaluate pitting risk. (C) 2020 Elsevier Ltd. All rights reserved.

Consequence of Galvanic Displacement Reaction on Digital Photocorrosion of GaAs/Al0.35Ga0.65As Nanoheterostructures

GaAs/AlGaAs semiconductor nanoheterostructures have found attractive application in the field of biosensing based on the effect of digital photocorrosion (DIP). The sensitivity of semiconductor-nanoheterostructure-based biosensors depends on the precision of controlling the process of DIP, which is highly sensitive to the surface presence of electrically charged biomolecules. To explore further this process, we have investigated the role of a galvanic displacement (GD) reaction on DIP of GaAs/Al0.35Ga0.65As (001) nanoheterostructures. Deposition of ionic gold on the GaAs surface induces spontaneous electron transfer between the semiconductor and ionic gold, which affects the photocorrosion of GaAs/AlGaAs layers observed simultaneously with the photoluminescence effect. The immediate consequence of the electron transfer from GaAs toward Au3+ is a significantly increased rate of DIP. At the same time, the formation of neutralized gold nanoparticles and Au-Ga alloy takes place on the surface of photocorroding nanoheterostructures. In the presence of 2.8% solution of ammonia and 0.1 mM gold chloride, a significantly reduced rate of deposition of gold nanoparticles is observed. This allows achieving layer-by-layer removal of the investigated material, which is sensitive to perturbations induced by surface immobilized electrically charged molecules. We have elaborated various factors stimulating photocorrosion of the GaAs/Al0.35Ga0.65As nanoheterostructures and we demonstrate the biosensing potential of an innovative GD-based DIP sensor.

Kraft Lignin Solubility and Its Chemical Modification in Deep Eutectic Solvents

Lignin stands as a promising raw material to produce commodities and specialty chemicals, yet its poor solubility remains a big challenge. Recently, deep eutectic solvents (DES) have been proposed as sustainable solvents with high potential to dissolve and valorize lignin. In the present study, the ability of DES based on cholinium chloride ([Ch]Cl) combined with alcohols and carboxylic acids as hydrogen bond donors (HBDs) to dissolve kraft lignin and to change its chemical structure was examined. The influence of the chemical nature of HBDs, water content, and HBD:hydrogen bond acceptor (HBA) molar ratio on the solubility of kraft lignin in DES was studied (313.15 K). The kraft lignin solubility was enhanced by increasing both the HBD’s carbon chain length and the molar ratio, with [Ch]Cl:HEXA (1,6-hexanediol) and [Ch]Cl:MaleA (maleic acid) being the best studied solvents for kraft lignin dissolution, while the addition of water was a negative factor. The thermal treatments (393.15 K) of kraft lignin show that carboxylic acid-based DES promote chemical modifications to kraft lignin, including the disruption of several C-O covalent type bonds (e.g., beta-O-4, alpha-O-4 and alpha-O-alpha), while alcohol-based DES were found to be nonderivatizing solvents maintaining the lignin chemical structure. These results show the versatility of DES, which, depending on their chemical nature, may offer distinct strategies for lignin valorization.

Chloride Diffusion and Induced Reinforcement Corrosion in Concrete with Fly Ash and Ground-Granulated Blast-Furnace Slag Exposed to Marine Submerged Zone(1)

This paper investigates the influence of mineral admixtures fly ash (FA) and ground-granulated blast-furnace slag (GGBS), the byproducts of industry, on chloride ions migration and corrosion resistance performance. A novel preparation method of wire beam electrode (WEB) was also introduced to explore the excellent corrosion-resistant capacity of concrete with mineral admixtures. By comparing concrete specimens with and without FA and GGBS, the test result of wire beam electrode, rapid chloride migration (RCM), and electrochemical tests highlight the positive impact of fly ash and GGBS against chloride ions migration, respectively. Concrete with fly ash and GGBS supplies an advanced protection effect of ordinary Portland cement; meanwhile, CO2 emission amount can be significantly reduced. Moreover, homemade wire beam electrode was proved to be a novel and reliable test method against corrosion, which has agreement with the test result of an electrochemical device.

Retention of anions in cobalt hydroxide with Ni substitution to emphasize the role of anions and cations for high current density in oxygen evolution reactions

Herein, we report the fabrication of remarkably fine nickel-substituted alpha-Co(OH)(2) sheets using an ingenious co-precipitation method at a lower pH value. An alpha-CoNiOOH sheet retains the parent alpha-Co(OH)(2) structure consisting of both tetrahedral (Td) and octahedral (Oh) sites with the retention of interlayer chloride ions, which is in contrast to the previous reports. The as-synthesized alpha-CoNiOOH sheet exhibits excellent oxygen evolution reactions (OERs) and produces a current of 10 mA cm(-2) at an overpotential of merely 190 mV in an alkaline environment. Moreover, the alpha-CoNiOOH sheet attains an exceptionally high current density of 100 mA cm(-2) at a low overpotential of only 270 mV. Additionally, this electrocatalyst possesses a 33 mV dec(-1) Tafel slope with higher values of TOF (11 s(-1)) and double-layer capacitance (7.76 mF cm(-2)). This enhancement is attributed partially to the substitution of Ni during the conversion of alpha-Co(OH)(2) to alpha-CoNiOOH and partially to the exceptionally thin sheets allowing potential octahedral sites for improved oxygen evolution reactions.
