Yang, Jung-Eun published the artcileSkin-protective and anti-inflammatory effects of Hibiscus syriacus L. (Mugunghwa): a comparative study of five parts of the plant, HPLC of Formula: 30931-67-0, the publication is Pharmacognosy Magazine (2020), 16(67), 183-191, database is CAplus.

Aim: The skin barrier is vulnerable to internal and external elements. However, certain plant extracts have promise for protecting the skin. Hibiscus syriacus L. is a Korean national plant (mugunghwa) that has been traditionally used to treat some skin diseases; however, its pharmacol. activities are poorly understood. The present study has evaluated the skin-protective effect of mugunghwa flowers (MF), cortexes (MC), roots (MR), leaves (ML), and seeds (MS) in external factor-stimulated human epidermal keratinocytes (HaCaTs), normal human dermal fibroblasts (NHDFs), and a widely used murine macrophage cell line (RAW 264.7 cells). Materials and Methods and Results: The active components were identified as palmitic acid and linoleic acid by high-performance liquid chromatog. anal. The parts of mugunghwa had low 2,2-diphenyl-1-picrylhydrazyl scavenging activities but moderate 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt scavenging capacity. All parts’ extracts at 100μg/mL decreased nitric oxide production in inflammation-induced RAW 264.7 cells and mRNA expression of the cytokines interleukin-6/1β and the enzymes inducible nitric oxide synthase/cyclooxygenase-2. On HaCaTs, MF, MC, and MR (10-50μg/mL) significantly increased hyaluronan production over that of controls. Moreover, MF activated NAD (P) H:quinone oxidoreductase 1 and heme oxygenase-1 and inhibited intracellular reactive oxygen species production Treatment with MF, MC, MR, ML, and MS (10μg/mL) reduced the scratching wound site in NHDFs to be considered by vascular endothelial growth factor signaling activation. Conclusion: Taken together, among all the five parts of the mugunghwa plant, MF effectively inhibited lipopolysaccharide, UV B irradiation, and scratching wound-induced inflammation in skin cells.

Mendes, Sophia F. published the artcileUltrafiltration process for lignin-lean black liquor treatment at different acid conditions, Related Products of thiazole, the publication is Separation Science and Technology (Philadelphia, PA, United States) (2022), 57(12), 1936-1947, database is CAplus.

Black liquor treatment by acid precipitation produces two main streams: the high purity precipitated lignin and the lignin-lean black liquor (a diluted lignin solution). Here, we evaluated the ultrafiltration process for lignin recovery from lignin-lean black liquor at different pH values (9.0, 9.5 and 10.0). The ultrafiltration process was able to retain 83 ± 0.5% of lignin from the lignin-lean black liquor at pH 9.0. The permeate flux increased with the decrease in pH value (steady state flux of 5.3 ± 0.0 L h-1m-2 at pH 9.0). Cake formation was the main fouling occurrence during lignin-lean black liquor filtrations. The weight average mol. weight of the lignin-lean black liquor decreased from 1866 to 1208 Da after the ultrafiltration process. The pH value did not significantly influence the mol. weight of permeate stream. Permeate samples presented lower hydroxyl content and higher syringyl(S):guaiacyl(G) ratios than feed samples. Thus, the ultrafiltration process was able to concentrate lignin from the lignin-lean black liquor and to produce a permeate with a narrow mol. weight distribution. The precipitation at more acid conditions is suggested to improve permeate flux lignin retention from lignin-lean black liquor.

Gorjanovic, Stanislava Z. published the artcileSerbian aromatized wine “Bermet”: electrochemical, chemiluminescent and spectrophotometric determination of antioxidant activity, SDS of cas: 30931-67-0, the publication is Journal of the Serbian Chemical Society (2020), 85(4), 517-529, database is CAplus.

Serbian aromatized wine “Bermet” from grapes grown on Fruska Gora Mountain has been in production since the 15th century. Ten com. Bermets produced according to the traditional procedure by different manufacturers, and six prepared within the scope of this study were assessed for antioxidant (AO) activity using electrochem., chemiluminescent and spectrophotometric AO assays. D.c. polarog. assay based on the decrease of anodic current of [hydrogen(peroxido)(1-)]hydroxidomercury(II) complex formation in alk. H₂O₂ solution at potential of mercury oxidation, chemiluminescent H₂O₂ scavenging assay, as well as commonly used spectrophotometric assays (2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) based Trolox equivalent antioxidant capacity (TEAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP)) were used. Total phenolic content (TPC) was determined by Folin-Ciocalteu assay. The results obtained were correlated using regression anal., ANOVA and F-test. An integrated approach to AO capacity determination allowed a more comprehensive comparison between samples. The approach is based on the introduction of the relative antioxidant capacity index, calculated by assigning each AO assay equal weight, and by PCA anal. In addition, the introduction of phenolic antioxidant coefficients, calculated as the ratio between individual AO capacity and TPC, enabled a better understanding of their relation.

Chalmpes, Nikolaos published the artcileGraphene oxide-cytochrome C multilayered structures for biocatalytic applications: Role of surfactant in Langmuir-Schaefer layer deposition, Recommanded Product: Ammonium 2,2′-(hydrazine-1,2-diylidene)bis(3-ethyl-2,3-dihydrobenzo[d]thiazole-6-sulfonate), the publication is ACS Applied Materials & Interfaces (2022), 14(22), 26204-26215, database is CAplus and MEDLINE.

Graphene, a two-dimensional single-layer carbon allotrope, has attracted tremendous scientific interest due to its outstanding physicochem. properties. Its monat. thickness, high sp. surface area, and chem. stability render it an ideal building block for the development of well-ordered layered nanostructures with tailored properties. Herein, biohybrid graphene-based layer-by-layer structures are prepared by means of conventional and surfactant-assisted Langmuir-Schaefer layer deposition techniques, whereby cytochrome C mols. are accommodated within ordered layers of graphene oxide. The biocatalytic activity of the as-developed nanobio-architectures toward the enzymic oxidation of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt and decolorization of pinacyanol chloride is tested. The results show that the multilayer structures exhibit high biocatalytic activity and stability in the absence of surfactant mols. during the deposition of the monolayers.

Saha, Rituparna published the artcileElectrochemical analysis of Catechol polymerization in presence of Trametes versicolor laccase and the mediator ABTS, Safety of Ammonium 2,2′-(hydrazine-1,2-diylidene)bis(3-ethyl-2,3-dihydrobenzo[d]thiazole-6-sulfonate), the publication is Enzyme and Microbial Technology (2022), 109934, database is CAplus and MEDLINE.

The phenolic compound catechol has found various applications in the industry but is often discharged untreated in industrial effluents. Catechol is highly toxic and adversely affects the environment. This has increased extensive investigation into elucidating the effects of various synthetic elements or different biocatalysts on catechol, thereby leading the way to its bioremediation. Hence, an electrochem.-based study on catechol in the presence of the enzyme laccase could provide a basic understanding of the unique characteristics exhibited by catechol, thus facilitating a distinct perspective to its subsequent treatment and removal. The present study focuses on the electrochem. characterization of catechol based on the oxidation of laccase and the redox mediator 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Catechol exhibited distinct electrochem. behavior across various concentrations The unique electroactive nature of ABTS assisted in the polymerization of catechol which was found to be concentration-dependent. Laccase produced a higher oxidation-reduction rate, thereby producing a much more stable condition for the polymerization of catechol. However, with the laccase-mediator system (LMS), the catechol polymerization rate was distinctly higher and more gradual with the enzyme utilizing the electroactive species produced by ABTS to increase the electron transfer and producing a combinatorial impact on the phenolic compound This study could rightly serve as the building block in developing future technologies like wastewater treatment and biosensors for catechol bioremediation.

Tran, Tai Duc published the artcileDNA-copper hybrid nanoflowers as efficient laccase mimics for colorimetric detection of phenolic compounds in paper microfluidic devices, Formula: C18H24N6O6S4, the publication is Biosensors & Bioelectronics (2021), 113187, database is CAplus and MEDLINE.

Laccases are important multicopper oxidases that are involved in many biotechnol. processes; however, they suffer from poor stability as well as high cost for production/purification Herein, we found that DNA-copper hybrid nanoflowers, prepared via simple self-assembly of DNA and copper ions, exhibit an intrinsic laccase-mimicking activity, which is significantly higher than that of control materials formed in the absence of DNA. Upon testing all four nucleobases, we found that hybrid nanoflowers composed of guanine-rich ssDNA and copper phosphate (GNFs) showed the highest catalytic activity, presumably due to the affirmative coordination between guanine and copper ions. At the same mass concentration, GNFs had similar Km but 3.5-fold higher Vmax compared with those of free laccase, and furthermore, they exhibited significantly-enhanced stability in ranges of pH, temperature, ionic strength, and incubation period of time. Based on these advantageous features, GNFs were applied to paper microfluidic devices for colorimetric detection of diverse phenolic compounds such as dopamine, catechol, and hydroquinone. In the presence of phenolic compounds, GNFs catalyzed their oxidation to react with 4-aminoantipyrine for producing a colored adduct, which was conveniently quantified from an image acquired using a conventional smartphone with ImageJ software. Besides, GNFs successfully catalyzed the decolorization of neutral red dye much faster than free laccase. This work will facilitate the development of nanoflower-type nanozymes for a wide range of applications in biosensors and bioremediation.

Kaseke, Tafadzwa published the artcileOxidative stability of pomegranate seed oil from blanched and microwave pretreated seeds: Kinetic and thermodynamic studiaaafes under accelerated conditions, HPLC of Formula: 30931-67-0, the publication is Journal of Food Processing and Preservation (2021), 45(10), e15798, database is CAplus.

This work aimed to evaluate the effects of blanching and microwave heating of pomegranate seed on the oxidative stability and shelf-life of ultrasound-assisted and ethanol extracted oil. Pomegranate seeds (cv. Herskawitz) were independently blanched at 95°C for 3 min and microwave heated at 261 W for 102 s. The oil samples were subjected to accelerated oxidation (30, 40, and 50°C) to evaluate lipid oxidation kinetics, thermodn. parameters, and estimate the shelf-life. The Arrhenius model and activated complex theory were used to estimate the energy for activation (E_a), enthalpy (ΔH ), entropy (ΔS ), and Gibbs-free energy (ΔG ), which varied from 6.2 to 8.59 kJ/mol, 3.69 to 6.38 kJ/mol, -146.62 to -155.06 J/K mol^-1, and 48.13 to 64.74 kJ/mol, resp. According to the thermodn. parameters, the lipid oxidation reactions in all oil samples were non-spontaneous, endothermic, and endergonic. Based on the developed Arrhenius models, blanching of pomegranate seed increased the oil shelf-life at 25°C from 21 to 24 days, while microwave pretreatment did not change the oil shelf-life. Seed pretreatment is a novel approach that could be used to enhance the oil antioxidant properties. This study has established that the blanching of seeds is beneficial in enhancing the storability and shelf life of pomegranate seed oil (PSO). In addition, the study has demonstrated that antioxidant compounds and fatty acid composition are indispensable factors in PSO oxidation The findings are useful in the design and establishment of PSO packaging, storage conditions, and application of modern technologies such as encapsulation to maximize its storability and retain the health-promoting properties.

The balsam poplar (Populus balsamifera L.) buds that grow in Lithuania are a polyphenol-rich plant material with a chem. composition close to that of propolis. In order to potentially adapt the extracts of this plant’s raw material for therapeutic purposes, it is important to carry out detailed studies on the chem. composition and biol. activity of balsam poplar buds. An important step is to evaluate the yield of polyphenols by different extraction methods and using different solvents. According to our research, extracts of balsam poplar buds collected in Lithuania are dominated by p-coumaric (496.9-13,291.2μg/g), cinnamic acid (32.9-11,788.5μg/g), pinobanksin (34.9-1775.5μg/g) and salicin (215.3-1190.7μg/g). The antioxidant activity of poplar buds was evaluated by the ABTS (2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (ferric-reducing antioxidant power) methods, all extracts showed antioxidant activity and the obtained results correlated with the obtained amounts of total phenolic compounds in the extracts (ABTS r = 0.974; DPPH r = 0.986; FRAP r = 0.955, p <0.01). Studies of antimicrobial activity have shown that ethanolic extracts have an antimicrobal activity effect against Staphylococcus aureus, Enterococcus faecalis and Escherichia coli. The extracts showed a better antimicrobal activity against gram-pos. bacteria.

In this study, the degradation of polyaromatic hydrocarbons (PAH) present in naturally contaminated soil by laccases was evaluated. For that purpose, laccase was produced by solid-state fermentation (SSF) on agroindustrial residues by Trametes versicolor and Agrocybe aegerita. At the same time, com. laccases from T. versicolor and Aspergillus sp. (Novozym 51,003) were used. Material and methods: Contaminated soil was collected at a dumping site in Lagos, Nigeria, 15-30 cm depth, with a total measurement of 74.87 mg kg-1 of PAH (UHPLC) and 235.26 mg kg-1 of metals (ICP). Soil rehabilitation was evaluated in amber bottles containing 20 g contaminated soil, 20 mL of 10 U g-1 of different laccases and 1 mM of mediators (ABTS, ferulic and coumaric acid) for 12 days. Results and discussion: After 12 days of treatment with laccases and mediators, the total PAH in soil was reduced to 28.20 mg kg-1 and 33.40 mg kg-1 by the laccases from A. aegerita and T. versicolor strains studied in this work, resp., and to 42.23 mg kg-1 and 39.46 mg kg-1 by the action of the com. laccases from T. versicolor laccase and Aspergillus sp., resp. Despite redox mediators such as 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), ferulic acid and coumaric acid were studied; it was observed that laccase alone could also achieve high degradation of the contaminants load. In general, ABTS and ferulic acid were the most effective mediators in PAH degradation Despite the high price, laccases and laccase-mediator system (LMS) may degrade or transform different pollutants in real environment and work very efficiently in a first approach to the rehabilitation of soil.
