The combined effects of external carbonation and internal chloride transport are the main reasons leading to the degradation of concrete structures manufactured with sea sand. To evaluate the degradation process of sea-sand concrete structures, a mathematical model for describing the redistribution of internal chlorides in sea-sand concrete exposed to atmospheric carbonation was proposed in this study. In the proposed model, changes in porosity, saturation degree, and the release of bound chlorides under the carbonation were considered. The numerical simulation of proposed model was executed by COMSOL software in a concrete model generated with random aggregates, which is verified to fit well with the experimental data obtained from a case study. In the modelling results, the chloride concentration in pore solution was decreased with the deeper depth after redistribution. However, on the chloride profile with the unit of wt% of concrete, a ‘pseudo enrichment’ of chlorides content was found after chloride redistribution and verified to be caused by the unit conversion. In conclusion, the proposed model could be used to predict the service life of sea-sand concrete structures exposed to atmospheric environment. (C) 2020 Elsevier Ltd. All rights reserved.

Background: Khaya gum is a bark exudate from Khaya senegalensis (Maliaecae) that has drug carrier potential. This study aimed to formulate and comparatively evaluate metformin-loaded microspheres using blends of khaya gum and sodium alginate. Khaya gum was extracted and subjected to preformulation studies using established protocols while three formulations (FA; FB and FC) of metformin (1% w/v)-loaded microspheres were prepared by the ionic gelation method using 5% zinc chloride solution as the cross-linker. The formulations contained 2% w/v blends of khaya gum and sodium alginate in the ratios of 2:3, 9:11, and 1:1, respectively. The microspheres were evaluated by scanning electron microscopy, Fourier transform-infrared spectroscopy, differential scanning calorimetry, entrapment efficiency, swelling index, and in vitro release studies. Results: Yield of 28.48%, pH of 4.00 0.05, moisture content (14.59% +/- 0.50), and fair flow properties (Carr’s index 23.68 +/- 1.91 and Hausner’s ratio 1.31 +/- 0.03) of the khaya gum were obtained. FTIR analyses showed no significant interaction between pure metformin hydrochloride with excipients. Discrete spherical microspheres with sizes ranging from 1200 to 1420 mu m were obtained. Drug entrapment efficiency of the microspheres ranged from 65.6 to 81.5%. The release of the drug from microspheres was sustained for the 9 h of the study as the cumulative release was 62% (FA), 73% (FB), and 80% (FC). The release kinetics followed Korsmeyer-Peppas model with super case-II transport mechanism. Conclusion: Blends of Khaya senegalensis gum and sodium alginate are promising polymer combination for the preparation of controlled-release formulations. The blend of the khaya gum and sodium alginate produced microspheres with controlled release properties. However, the formulation containing 2:3 ratio of khaya gum and sodium alginate respectively produced microspheres with comparable controlled release profiles to the commercial brand metformin tablet.

Anoctamin1 (ANO1), a calcium-activated chloride ion channel (CaCC), is associated with various physiological functions including cancer progression and metastasis/invasion. ANO1 has been considered as a promising target for cancer therapeutics as ANO1 is over-expressed in a variety of cancers including glioblastoma (GBM) and inhibition of ANO1 has been reported to suppress cell proliferation, migration and invasion in GBM. GBM is one of the most common and aggressive cancers with poor prognosis with median survival for 15 months. Lack of effective treatment options against GBM emphasizes urgent necessity of effective GBM therapeutics. In an effort to discover potent and selective ANO1 inhibitors capable of inhibiting GBM cells, we have designed and synthesized a series of new 2-aminothiophene-3-carboxamide derivatives and performed SAR studies using both fluorescent cellular membrane potential assay and whole-cell patch-clamp recording. We observed that among these substances, 9c and 10q strongly suppress ANO1 channel activities and possess remarkable selectivity over ANO2. Unique structural feature of 10q, a cyclopentane-fused thiophene-3-carboxamide derivative, is the presence of benzoylthiourea functionality which dramatically contributes to activity. Both 9c and 10q suppress more strongly proliferation of GBM cells than four reference compounds including 3, Ani-9 and are also capable of inhibiting much more strongly colony formation than reference compounds in both 2D colony formation assay and 3D soft agar assay using U251 glioma cells. In addition, 9c and 10q suppress far more strongly migration/invasion of GBM cells than reference compounds. We, for the first time, found that the combination of ANO1 inhibitor (9c or 3) and temozolomide (TMZ) brings about remarkable synergistic effects in suppressing proliferation of GBM cells. Our study may provide an insight into designing selective and potent ANO1 inhibitors aiming at GBM treatment. (C) 2020 Published by Elsevier Masson SAS.

Ethnopharmacological relevance: Launaea acanthodes (Boiss.) O. Kuntze is native to semiarid regions of central Iran, traditionally used in the treatment of numerous disorders including diabetes. Aim of the study: The current study aimed to explore hypoglycemic activity of Launaea acanthodes extract in streptozotocin-induced diabetic rats. Furthermore, gene expression study was carried out to examine expression levels of key glucose metabolism-related genes. Methods: For in vitro study, Folin-Ciocalteus, DPPH and aluminum chloride colorimetric assays were used to determine the total phenolic content, antioxidant capacity and total flavonoid content of extracts, respectively. For in vivo study, streptozotocin-induced diabetic Wistar rats were orally administered with metformin (50 mg/ kg) and various doses of extracts (100, 200 and 400 mg/kg body weight) for 28 days. Fasting blood glucose, body weight, food and water intake were assessed during the course of treatment. At the end of the intervention, oral glucose tolerance test (OGTT), lipid profile and glycated hemoglobin (HbA1c) were evaluated. Furthermore, functional liver enzymes, oxidative stress markers and histopathology of pancreas were examined. Lastly, quantitative real time polymerase chain reaction (qRT-PCR) was applied to explore the mRNA levels of genes relevant to glucose metabolism in the pancreas and liver tissues of diabetic rats. Results: Based on the in vitro results, the hydroalcoholic extract revealed potential radical scavenging activity and contained highest amount of phenolic and flavonoid. The in vivo results demonstrated that the extract lowered fasting blood glucose level, increased the body weight, restored the alterations in the levels of water and food intake, attenuated HbA1c, improved lipid profile and ameliorated the OGTT in diabetic rats. The extract administration alleviated the histopathological changes in the pancreas, suppressed malondialdehyde (MDA) level and further restored attenuated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutathione peroxidase (GPx) and superoxide dismutase (SOD) in diabetic rats. Analysis of real time PCR data showed that extract administration reversed the expression levels of hepatic glucokinase (GK), phosphenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase). Meanwhile, the extract upregulated the expression level of glucose transporter-2 (GLUT-2) and pancreatic-duodenal homeobox (PDX-1) in diabetic rats. Conclusion: Collectively, the results demonstrate that Launaea acanthodes hydroalcoholic extract exerts hypoglycemic effect possibly via regulating key enzymes of glucose metabolism and ameliorating pancreatic dysfunction through its antioxidant properties.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 81927-55-1, Name is Benzyl 2,2,2-trichloroacetimidate, SMILES is ClC(Cl)(Cl)C(=N)OCC1=CC=CC=C1, in an article , author is Hu, Neng, once mentioned of 81927-55-1, SDS of cas: 81927-55-1.

The risk of extensive exposure of the human epidermis to solar ultraviolet radiation is significantly increased nowadays. It not only induces skin aging and solar erythema but also increases the possibility of skin cancer. Therefore, a simply prepared, highly sensitive, and optically readable device for monitoring the solar ultraviolet radiation is highly desired for the skin health management. Because of the photoinitiated polymerization triggered by graphene-carbon nitride (g-C3N4) under ultraviolet radiation, g-C3N4 is homogeneously distributed in the hybrid hydrogels containing N-isopropylacrymide (NIPAM), poly(ethylene glycol) methyl ether methacrylate (OEGMA(300)), and sodium alginate (SA). By further immersing the hybrid hydrogels into calcium chloride solution, hybrid alginate-Ca2+/P(NIPAM-co-OEGMA(300))/g-C3N4 interpenetrating polymeric network (IPN) hydrogels are obtained. Due to the homogeneous distribution of g-C3N4 and the existence of thermoresponsive polymers, the hybrid IPN hydrogels present good adsorption capability and high degradation efficiency for methylene blue (MB) especially at high temperature under ultraviolet radiation. Based on this unique property, the bracelet monitoring skin health is prepared by simply immersing the hybrid IPN hydrogels into the MB solution and then wrapping it with PET foil. Because the immersion time for the top, middle, and bottom parts of the hybrid IPN hydrogels is gradually increased, their colors vary from light to dark blue. A longer time is required for the discoloration of the darker part under solar ultraviolet radiation. Thus, the bracelet can be used to conveniently monitor the dose of solar ultraviolet radiation by simply checking the discoloration in the bracelet under sunshine. Due to the facile preparation and low cost of the bracelet, it is a promising candidate for wearable devices for skin health management.

The volatilization of heavy metals during combustion of polyvinyl chloride after hydrothermal carbonization

This paper experimentally investigated the volatilization characteristic of five heavy metals (cadmium, chromium, nickel, lead and zinc) during combustion of hydrochars of polyvinyl chloride with hydrothermal carbonization pretreatment. The differences of volatilization rate of cadmium and lead between polyvinyl chloride and hydrochars were within 5%, indicating that hydrothermal carbonization had no significant effects on their volatilization behavior. Higher hydrothermal carbonization temperature and lower combustion temperature resulted in lower volatilization rate of zinc. For chromium and nickel, although their volatilization rates were lowered, the absolute volatilization rates increased remarkably because of the increase of original concentrations. Nevertheless, the total emissions of heavy metals studied reduced. Hydrothermal carbonization performed at 230 degrees C showed the most significant absolute volatilization rates reductions ranged from 79.2% to 86.8% depending on combustion temperature. The highest concentrations of chromium and nickel in bottom ash reached up to 20.1 g/kg and 7.9 g/kg, respectively. (C) 2020 Elsevier Ltd. All rights reserved.

Succinyl chitosan gold nanocomposite: Preparation, characterization, in vitro and in vivo anticandidal activity

Herein, we have successfully synthesized a novel N-Succinyl chitosan/gold nanocomposite (N-SuC/Au NC) using N-SuC and gold(III) chloride, and investigated the biocompatibility and antifungal activity. The synthesized N-SuC/Au NC was characterized by UV-visible spectroscopy, X-ray diffraction, field emission scanning electron microscope, and inductively coupled plasma atomic emission spectroscopy. The N-SuC/Au NC exhibited a strong inhibition effect towards pathogenic Candida albicans. Morphological analysis revealed the destruction of C. albicans cell membrane due to N-SuC/Au NC treatment. The in vitro and in vivo toxicity of N-SuC/Au NC was analyzed with HEK293T mammalian cells and zebrafish larvae, respectively. The synthesized N-SuC/Au NC demonstrated no cytotoxicity towards HEK293T cells up to 1200 mu g/mL concentration. The survival rate of the zebrafish larvae at 120 hpf, was found as 100% up to 1200 mu g/mL of N-SuC/Au NC exposure. The in vivo studies further confirmed the inhibitory effects of N-SuC/Au NC on the formation of C. albicans hyphae in infected zebrafish muscle tissue. (C) 2020 Elsevier B.V. All rights reserved.

Enhancement of the thermal analysis of power cables installed in polyvinyl chloride (PVC) ducts under continuous and cyclic current loading conditions

A study of the performance of power cables installed inside non-metallic ducts is presented here. Cable capacity calculations for this type of installation are done. The thermal analysis of cables inside ducts which are installed in air as riser or buried in soils is presented. According to IEC 60287 cables can be installed in fibre ducts in concrete layer surrounded by the soil, in this article it is proposed to install the cables in PVC ducts directly buried in the soil. Based on IEC 60287-1-3 and IEC 60853-2 standards proposed models in steady state and dynamic cable loadings are constructed. The proposed equivalent thermal models are used in the calculations of the cable components temperature for cables installed in ducts. It is concluded that very high increase in cable conductor temperature is observed when the cable is installed in duct and used as riser or even when it is installed in duct buried in soil. Significant decrease in the temperature of the cable conductor can be noticed when the cable is directly buried in the soil compared with that installed in ducts.

Chronic tribasic copper chloride exposure induces rat liver damage by disrupting the mitophagy and apoptosis pathways

Despite the fact that copper (Cu) is a vital micronutrient to maintain body function, high doses of Cu through environmental exposure damage various organs, especially the liver, which is the main metabolic organ. To investigate the influence of long-term Cu-induced toxicity on mitophagy and apoptosis in rat liver, 96 sevenmonth-old male Sprague-Dawley rats were fed TBCC for 24 weeks. The results revealed that exposure to high Cu concentrations could promote oxidative stress liver injury by increasing the hepatic function index (ALT, AST and ALP) and MDA content, while reducing the activity of antioxidant enzymes (T-SOD, GSH-Px and CAT) related to oxidative stress. Consistent with histopathological observations, proper dietary Cu (15-60 mg/kg) could improve antioxidant stress levels and induce a dose-dependent increase in the mRNA expression of mitophagy-related genes, whereas a high Cu concentration (120 mg/kg) could cause severe liver impairment and ultrastructural changes and a reduction in mitophagosomes, accompanied by downregulation of Atg5, Beclin1, Pink1, Parkin, NIX, P62 and LC3B. The expression of apoptosis-related genes (Bax, Bax/Bcl-2, Caspase3, Cytc and p53) and proteins (Caspase3 and p53) was upregulated with the addition of dietary Cu. The results demonstrated that an appropriate dose of TBCC could improve liver function by promoting mitophagy and Cu enzymes that play antioxidative roles, while the accumulation of excess Cu could induce liver lesions by enhancing apoptosis and inhibiting mitophagy pathways.
