CREB1 protects against the renal injury in a rat model of kidney stone disease and calcium oxalate monohydrate crystals-induced injury in NRK-52E cells

Kidney stone disease (KSD) is a common urinary disease with increasing prevalence worldwide. In this study, we investigated the effect of cyclic AMP responsive element binding protein (CREB) 1 in a KSD model of rat and calcium oxalate monohydrate (COM) crystals-treated NRK-52E cells. Rats were pretreated with lentivirus (LV)CREB1 vector or LV-control vector and administrated with ethylene glycol + ammonium chloride to induce KSD. It was found that CREB1 was activated in the renal tissue of non-treated KSD rats. Pretreating with LV-CREB1 vector significantly enhanced CREB1 expression in KSD rats. Biochemical analysis for serum and urine showed that upregulation of CREB1 could improve the renal function of KSD rats. Histological analysis confirmed that upregulation of CREB1 alleviated the renal injury in KSD rats. Moreover, the upregulation of CREB1 suppressed the apoptosis in renal tissue of KSD rats through regulating apoptosis-associated proteins. Further study showed that the upregulation of CREB1 could attenuate the oxidative stress in KSD rats as well. More interestingly, the upregulation of CREB1 enhanced the activity of complex I and complex III and the expression of mitochondrial cytochrome c, implicating the effect of CREB1 on improving mitochondrial function in KSD rats. In vitro study confirmed that upregulation of CREB1 inhibited the apoptosis and oxidative stress, while improved the mitochondrial function of NRK-52E cells treated with COM crystals, demonstrating the protective effect of CREB1 on COM crystals-induced renal epithelial cell injury. Therefore, CREB1 might be served as a promising target in the prophylaxis and treatment of KSD.

Combined effects of supplementary cementitious materials (silica fume, GGBS, fly ash and rice husk ash) and steel fiber on the hardened properties of recycled aggregate concrete

Recycled aggregate concrete (RAC) is now getting much more attention than ever as a likely substitute for natural aggregate concrete, credited to the growing interest of many countries towards the sustainable environment and economy. To increase the goodwill of RAC its performance in terms of strength and durability needs to be optimized. This research article presents the effects of combined incorporation of supplementary cementitious materials (SCMs) and hook-ended steel fibers (HSF) on compressive behavior and durability of RAC. In this study, four different SCMs (i.e. silica fume (SF), ground granulated blast furnace slag (GGBS), fly ash (FA), and rice husk ash (RHA)) were used in RAC with 0% and 1% HSF, respectively. SF, GGBS, FA, and RHA were respectively used as 10%, 30%, 20%, and 15% by mass replacement of ordinary Portland cement (OPC). Studied properties included compressive strength, elastic modulus, splitting tensile strength, water absorption (WA), chloride penetration (CP), and acid attack resistance (AAR). The results of testing indicate that mechanical strength and durability of RAC can be improved substantially by the combined incorporation of SCMs and HSF reinforcement. SCMs show more contribution towards the development of durability properties of RAC, whereas, HSF shows more contribution towards the development of mechanical properties and AAR. 10%SF + 1% HSF and 15%RHA + 1% HSF helped in the production of RAC having superior mechanical and durability properties compared to that of the plain RAC. Moreover, the benefits of combined addition of HSF and SCMs are notably higher than the sum of the benefits achieved through individual incorporation of HSF and SCMs. (C) 2020 Elsevier Ltd.

High conductivity and alkali-resistant stability of imidazole side chain crosslinked anion exchange membrane

Poly (aryl ether ketone) polymers (PAEKS) were synthesized by polycondensation of trimethyl hydroquinone, allyl bisphenol S and 4,4-difluorodiphenyl ketone as monomers. A series of uncrosslinked and crosslinked anion exchange membranes (AEMs) with diverse contents of 1-allyl-3-methylimidazolium chloride and 1-vinylimidazole were prepared by grafting and bromination reaction. The 1-vinylimidazole in the AEMs was simultaneously present as a crosslinked agent. (HNMR)-H-1 and FT-IR spectra demonstrated the structure of the above PAEKS and AEMs, respectively. TEM images and SAXS profiles showed the formation of distinct hydrophilic/hydrophobic microphase separation in the TCImP membranes, which offered vast of channels for ion transmission. Among them, TCImP-3 membrane showed the highest hydroxide conductivity of 0.144 S/cm at 80 degrees C. Compared with the uncrosslinked AEMs, the crosslinked AEMs exhibited slightly lower water uptake and swelling ratio. The crosslinked structures in the AEMs were helpful to improve the mechanical property and alkali-resistant stability of AEMs. The hydroxide conductivity of the TCImP-3 membrane kept 0.117 S/cm in 2 M NaOH solutions at 80 degrees C for 400 h. Meanwhile, crosslinked AEMs showed excellent thermostability. We believe that TCImP membranes are a promising AEMs material.

Effect of Environment on the Work Hardening Behavior of AA 7004

The influence of 3.5 wt pct NaCl on the work-hardening response of AA 7004 is investigated through subjecting the tensile data to Kock-Mecking analysis. Due to the exposure to chloride, the decay in the work-hardening rate (-d theta/d sigma) increases by similar to 28 pct when the alloy has GP zones and decreases by similar to 22 pct when eta ‘/eta precipitates are present. In contrast, no significant variation in ultimate tensile strength and elongation values are observed for the alloy, although it suffered embrittlement which results in tearing topography surfaces. Accordingly, -d theta/d sigma seems to be a more reliable parameter to assess the environmentally assisted cracking (EAC) susceptibility of the less EAC susceptible AA 7004.

Synthetic Route of 95-69-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 95-69-2 is helpful to your research.

Service life of reinforced concrete seawalls suffering from chloride attack: Theoretical modelling and analysis

This paper presents a theoretical model for predicting the service life of reinforced concrete (RC) seawalls under chloride attack. The developed theoretical model not only takes into account the effects of chloride-induced degradation, but also properly considers the external water and earth pressures acting on the RC seawalls. To theoretically model the service life of the RC seawall, the whole service life is divided into the initiation stage for chloride ions diffusion and the propagation stage for corrosion products development. The diffusion of chloride ions in the seawall is simulated by a two-sided chloride diffusion model on the basis of the Fick’s second law, which is sufficiently validated by the corresponding ABAQUS numerical model. The propagation stage is modeled by a mechanical model that considers both the external pressures and the internal expansive pressure induced by the rust productions. Example analyses are conducted to illustrate the application of the model and investigate the effects of some key factors on the service life of RC seawall. The results show that the service life of reinforced concrete seawall increases with cover thickness, tensile strength of concrete, threshold chloride concentration, burial depth and surface load, while decreases with the increase of rebar diameter and water-cement ratio. The proposed theoretical model can serve as a theoretical base and benchmark for design and prediction of service life of coastal structures. (C) 2020 Elsevier Ltd. All rights reserved.

Characterization and corrosion behavior of electroless Ni-Mo-P/Ni-P composite coating in CO2/H2S/Cl- brine: Effects of Mo addition and heat treatment

The electroless Ni-Mo-P/Ni-P composite coating was applied on N80 carbon steel, and the effects of Mo addition and heat treatment on the corrosion resistance enhancement in CO2/H2S/Cl- brine were studied by electrochemical measurements and surface analysis techniques. The Mo addition in the as-deposited Ni-P coating causes the microstructural transformation from amorphous to crystalline due to the reduced P content, thereby suffering severe corrosion. The impaired corrosion performance of as-deposited Mo-incorporated coating is also originated from the absence of the oxide film on the coating surface. Nonetheless, the heat-treated Ni-Mo-P/Ni-P coating exhibits desirable corrosion resistance, which is reflected by the outstanding corrosion inhibition efficiency (eta = 96.1%). Heat treatment facilitates the formation of Ni4Mo phase and more importantly, the growth of an oxide film consisting of nickel and molybdenum oxides (H2S-immuned MoO3) with better passivation properties, which accounts for the remarkable corrosion resistance improvement.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 139631-62-2. Category: chlorides-buliding-blocks.

Elucidating the Role of Embedded Metal-Organic Frameworks in Water and Ion Transport Properties in Polymer Nanocomposite Membranes

Metal-organic frameworks (MOFs) have been extensively studied as promising nanofillers in developing high-performance polymer nanocomposite membranes (PNMs) for efficient water/ion separation applications. However, given the ambiguous role of embedded MOFs, achieving simultaneous improvement in both water permeability and water/ion selectivity of PNMs remains challenging. Here, we elucidates fundamental water and ion transport properties of MOF/PNMs to better understand the role of embedded MOFs in polymer matrices. We prepared freestanding PNMs consisting of a cross-linked poly(ethylene glycol) (XPEG)-based hydrogel and nanoporous zeolitic imidazole framework-8 (ZIF-8) exhibiting high diffusivity selectivity. The transport studies and material characterizations, especially with Raman mapping analysis showing a homogeneous distribution of permeating water molecules throughout ZIF-8/XPEG PNM, revealed that the incorporated ZIF-8 acts as an additional water-permselective channel inside the polymeric matrix, which leads to an unusual reverse-selective ion transport behavior. Ultimately, 20 wt % of ZIF-8 loading could significantly enhance both water permeability (similar to 240%) and water/NaCl selectivity (similar to 160%) compared to a pure polymer membrane by overcoming the conventional permeability-selectivity trade-off limitation. Our finding provides new insights for developing advanced PNMs for water/ion separation.

Imaging spectroscopies to characterize a 13th century Japanese handscroll, The Miraculous Interventions of Jizo Bosatsu

Scientific imaging of a large fragile work of art can be especially challenging, but especially rewarding to better grasp the complexity and changes that have occurred during its creation and lifetime. Here, noninvasive imaging, macro X-ray fluorescence (MAXRF) imaging spectroscopy and reflectance imaging spectroscopy, from the visible to the near infrared spectral range, are utilized to document a 14-m-long Japanese narrative handscroll, The Miraculous Interventions of Jizo Bosatsu. Due to the scroll’s age and its handling during past use as a teaching tool, it has a number of conservation needs and shows evidence of past repairs. The scroll has extensive and severe creasing, breaks and tears, as well as unstable and powdering pigments. Microscopic observation and scientific analyses were performed both to document the current condition of the scroll and to better understand its long history. Combining RIS and MAXRF allowed for pigment characterization through elemental and molecular information. While RIS and MAXRF previously have been applied to the study of other painted materials, their application to East Asian paintings is rare. The obstacles of the scroll’s length and fragile uneven surface were overcome by optimizing the setups of the two imaging systems. The MAXRF and RIS analyses, here focused on a select scene of the scroll, found certain original pigments common in early Japanese scroll paintings were used frequently, such as vermilion, iron-based compounds (yellow and red ochres), and copper-containing greens, while others occurred sparingly, such as azurite and red lead. A chloride-containing lead-based white pigment was employed. Faded organic colorants, notably indigo as well as an organic yellow/brown, could be detected but their vibrancy has been muted over the centuries. In the case of indigo, it may be visibly observed in some areas; however, analysis revealed its previously unknown presence mixed with a copper green in a select area. This focused study sets a foundation for further studies on both this object and other Asian works of art.

Uranium chemical species in LiCl-KCl eutectic under different conditions for the dissolution of U3O8

As a typical uranium oxide, the electrochemical behaviors of U3O8 in molten salt have attracted many research endeavors, but its dissolution behavior and related mechanism in molten salt has been less well understood. In this work, we reported the dissolution of U3O8 in LiCl-KCl eutectic with the assistance of NH4Cl, which has potential significance for the pyrochemical reprocessing of spent oxide fuels. The spectroscopic techniques such as fluorescence emission spectroscopy, UV-Vis absorption spectroscopy, and X-ray Absorption Fine Structure (XAFS) were used to determine the chemical species during the dissolution process of U3O8. The results show that U3O8 can be completely dissolved in molten salt under the air atmosphere, and it exists in the form of [UO2Cl4](2-). In contrast, under an argon atmosphere, the soluble [UO2Cl4](3-) and insoluble UO2 were detected as the main products. (C) 2020 Elsevier B.V. All rights reserved.

Salting Up and Salting Down of Bovine Serum Albumin Layers at the Air-Water Interface

The surface adsorption of bovine serum albumin in pure water and salted aqueous solutions was studied by neutron reflection. With the contrast match technique, the surface excess in null reflecting water as a function of the protein concentration was revealed. It is found that, in a concentration range from 1 ppm (parts per million, mg/L) to 1000 ppm, without salts, the surface excess shows a profound peak at around 20 ppm; with salts, the surface excess increases steadily with the protein concentration. When the surface excess at a specific protein concentration is viewed, the introduction of sodium chloride causes either a salting down effect (surface adsorption decline) or a salting up effect (surface adsorption increase), depending upon the protein concentration. The salting up effect is observed at the low (similar to 1 ppm) and high (similar to 1000 ppm) concentrations, and the salting down effect dominates the intermediate concentration range. The change in solution pH relative to the isoelectric point (PI) can act as a simple indicator for the salting up or salting down behavior. When the solution pH is shifted toward the PI by adding salts, surface adsorption enhances; when the solution pH is shifted away from the PI by adding salts, surface adsorption declines.
