Taxifolin improves disorders of glucose metabolism and water-salt metabolism in kidney via PI3K/AKT signaling pathway in metabolic syndrome rats

Aims: Our study was designed to explore the function and mechanism of taxifolin on glucose metabolism and water-salt metabolism in kidney with metabolic syndrome (MS) rats. Main methods: Spontaneous hypertensive rats were induced by fructose to establish MS model. Systolic blood pressure (SBP) and homeostasis model assessment of insulin resistance (HOMA-IR) were measured after 7 weeks of continuous administration with taxifolin. Kidney injury indices and histopathological evaluation were done. The apoptosis rate of primary kidney cells was detected by flow cytometry. Insulin signaling pathway related proteins and renal glucose transport-related proteins were detected by western blotting. We assessed the effects of taxifolin on sodium water retention and renin-angiotensin-aldosterone system (RAAS) in MS rats. We examined not only changes in urine volume, osmotic pressure, urinary sodium and urinary chloride excretion, but also the effects on NA(+)/K+-ATPase and RAAS indicators. We also detected changes in inflammatory factors by immunohistochemical staining and immunofluorescence. In vitro experiment, high glucose and salt stimulated NRK-52E cells. By adding the PI3K inhibitor (wortmannin) to inhibit the PI3K, the effects of inhibiting the PI3K/ AKT signaling pathway on glucose metabolism, water-sodium retention and inflammatory response were discussed. Key findings: Taxifolin effectively reversed SBP, HOMA-IR, the kidney indices and abnormal histopathological changes induced by MS. Besides, taxifolin called back the protein associated with the downstream glucose metabolism pathway of PI3K/AKT. It also inhibited overactivation of RAAS and inflammatory response. In vitro experiments have demonstrated that the PI3K/AKT signaling pathway plays an important role in this process. Significance: Taxifolin can improve homeostasis of glucose, inhibit overactivation of RAAS and reduce inflammatory response by PI3K/AKT signaling pathway.

Iron oxide nanoparticle synthesis using trigonella and tomato extracts and their antibacterial activity

Iron oxide nanoparticles (IONPs) were synthesised by combining the extracts of new plants (trigonella and tomato) with ferric chloride salt (FeCl3) via a simple chemical method at 200 degrees C for 2 hours. The biomolecules in the extracts play an important part in transforming FeCl3 to FeO NPs, which demonstrate antibacterial properties. IONPs were characterised via X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and Fourier-transform infrared spectroscopy (FT-IR). XRD revealed a crystallite size of 17 nm with a body centre cubic (BCC) structure (wustite) phase for FeO NPs made using trigonella extract. FeO NPs synthesised using tomato extract were 41 nm, and the diffraction peaks revealed a BCC structure phase with excellent crystal quality. FE-SEM images demonstrated that the average grain size of Fe2O3 without using any plant extract was approximately 31.36 to 125.5 nm, while for the FeO NPs using tomato extract, it was approximately 48.18 to 77.54 nm, and for trigonella extract, 27.91 to 40.94 nm. In the FT-IR spectra of IONPs with and without plant extract, a strong peak appeared at 699 cm(-1) for FeO NPs using trigonella extract and 655 cm(-1) using tomato extract. Antibacterial activity of IONPs was determined by growth inhibition zones of the gram-negative bacteria Klebsiellapneumonia and gram-positive bacteria Staphylococcus aureus. The growth inhibition zones for FeO NPs using trigonella extract were 42 and 47 mm, respectively. The zones for FeO NPs using tomato extract were smaller (30 mm and 35 mm, respectively). These NPs may be effective in healing infections caused by these bacteria.

Design and characterization of a chloride-free organic copper solution: Electrochemical synthesis of Zn/Cu/Sn precursor stack for CZTS-based photoconversion devices

In the present study, an ethylene glycol-based electrolyte is used to electrodeposit copper onto zinc for the synthesis of the Zn/Cu/Sn stack, precursor of Cu2ZnSnS4. The employed solution contains diethanolamine (DEA) which supports the formation of amine-complexes, whose features are studied by UV-vis absorption, ESI-MS, and FTIR measurements, providing insight on the optimal concentration of DEA for copper complexation. Cyclic voltammetries (CVs) are carried out at increasing [DEA]/[Cu2+] ratios, highlighting the amine effect on the reduction potential of the copper species. The displacement reaction between copper and zinc is investigated by immersion potential measurements, showing a direct correlation to the voltammetric data. The optimized copper solution resulted in a negligible displacement contribution, allowing the electrochemical synthesis of Mo-(sub)/Zn/Cu/Sn stack on a relatively large area (4 cm(2)). The metallic precursor is analyzed by SEM/EDS, AFM, XRD, and GDOES techniques. Finally, the kesterite CZTS phase is obtained through reactive annealing with elemental sulfur and it is characterized by SEM/EDS, XRD, and Raman spectroscopy. Photoelectrochemical water splitting on CZTS/CdS/Pt heterostructure is carried out in an aqueous solution at pH 6.85, showing a photocurrent of -5.05 mA/cm(2) at 0 V vs RHE. A maximum applied bias photon-to-current efficiency (ABPE) value of 2.15% was found at 0.84 V bias. (C) 2021 Elsevier Ltd. All rights reserved.

Corrosion behavior of carbon steel in dilute ammonia solution

This study explores the corrosion of carbon steel in ammonia solutions containing dissolved oxygen and chloride, simulating boilers under wet layup conditions. An adsorption mechanism is proposed in which ammonia is postulated to be an inhibiting species at low NH3 (i.e. 9.061 x 10(-5) M) but is an activating species at high concentration (0.001M-0.1 M) via the formation of a Fe(NH3)n(2+), with an apparent activation potential at about-0.4 VSCE. At higher potentials, the steel passivates through the formation of a defective oxide barrier layer that exhibits chloride-induced breakdown with the breakdown potential decreasing with increasing Cl-. However, oxide breakdown is inhibited by ammonia, which is postulated to be due to NH3 competing with Cl- for oxygen vacancies in the surface of the barrier oxide layer. Chloride accelerates steel corrosion, with the anodic branch of Fe electrodissolution shifting in the positive potential direction in solutions with increasing oxygen content. (C) 2020 Elsevier Ltd.

Veno-occlusive unloading of the heart reduces infarct size in experimental ischemia-reperfusion

Mechanical unloading of the left ventricle reduces infarct size after acute myocardial infarction by reducing cardiac work. Left ventricular veno-occlusive unloading reduces cardiac work and may reduce ischemia and reperfusion injury. In a porcine model of myocardial ischemia-reperfusion injury we randomized 18 pigs to either control or veno-occlusive unloading using a balloon engaged from the femoral vein into the inferior caval vein and inflated at onset of ischemia. Evans blue and 2,3,5-triphenyltetrazolium chloride were used to determine the myocardial area at risk and infarct size, respectively. Pressure-volume loops were recorded to calculate cardiac work, left ventricular (LV) volumes and ejection fraction. Veno-occlusive unloading reduced infarct size compared with controls (Unloading 13.9 +/- 8.2% versus Control 22.4 +/- 6.6%; p = 0.04). Unloading increased myocardial salvage (54.8 +/- 23.4% vs 28.5 +/- 14.0%; p = 0.02), while the area at risk was similar (28.4 +/- 6.7% vs 27.4 +/- 5.8%; p = 0.74). LV ejection fraction was preserved in the unloaded group, while the control group showed a reduced LV ejection fraction. Veno-occlusive unloading reduced myocardial infarct size and preserved LV ejection fraction in an experimental acute ischemia-reperfusion model. This proof-of-concept study demonstrated the potential of veno-occlusive unloading as an adjunctive cardioprotective therapy in patients undergoing revascularization for acute myocardial infarction.

The impact of chloride and chlorine radical on nitrite formation during vacuum UV photolysis of water

The impact of chloride ion and chlorine radical on the formation of nitrite was investigated under Vacuum-UV (VUV) photolysis of nitrate contaminatingwater. An increase in chloride concentration reduced nitrite formation in part due to the relatively high VUV absorption of chloride. The use of various radical scavengers, such as acetate and acetone, helped delineate the specific roles of hydroxyl radical (HO center dot) and chlorine radical (Cl-center dot) in oxidation and VUV photolysis of nitrate, and the subsequent formation of nitrite. HO center dot reduced nitrite formation due to its high reaction rate constant with nitrite. Nitrite formation in both chloride and dissolved organic carbon (DOC) containing solution depended primarily on their relative concentrations. Carbamazepine (CBZ) was also used to analyze the effect of Cl-center dot on both the degradation of CBZ and the formation of nitrite. Cl-center dot showed to significantly increase the degradation of CBZ, but it had little impact on the formation of nitrite. This paper, utilizing detailed experimental data combinedwith kineticmodeling andmechanistic analysis of VUV photolysis in the presence of chloride and nitrate, provides the necessary scientific guidance towards more effective and optimized applications of VUV technology for drinking water treatment.

Indirect Quantification of Glyphosate by SERS Using an Incubation Process With Hemin as the Reporter Molecule: A Contribution to Signal Amplification Mechanism

The indirect determination of the most used herbicide worldwide, glyphosate, was achieved by the SERS technique using hemin chloride as the reporter molecule. An incubation process between hemin and glyphosate solutions was required to obtain a reproducible Raman signal on SERS substrates consisting of silicon decorated with Ag nanoparticles (Si-AgNPs). At 780 nm of excitation wavelength, SERS spectra from hemin solutions do not show extra bands in the presence of glyphosate. However, the hemin bands increase in intensity as a function of glyphosate concentration. This allows the quantification of the herbicide using as marker band the signal associated with the ring breathing mode of pyridine at 745 cm(-1). The linear range was from 1 x 10(-10) to 1 x 10(-5) M and the limit of detection (LOD) was 9.59 x 10(-12) M. This methodology was successfully applied to the quantification of the herbicide in honey. From Raman experiments with and without silver nanoparticles, it was possible to state that the hemin is the species responsible for the absorption in the absence or the presence of the herbicide via vinyl groups. Likewise, when the glyphosate concentration increases, a subtle increase occurs in the planar orientation of the vinyl group at position 2 in the porphyrin ring of hemin over the silver surface, favoring the reduction of the molecule. The total Raman signal of the hemin-glyphosate incubated solutions includes a maximized electromagnetic contribution by the use of the appropriate laser excitation, and chemical contributions related to charge transfer between silver and hemin, and from resonance properties of Raman scattering of hemin. Incubation of the reporter molecule with the analyte before the conjugation with the SERS substrate has not been explored before and could be extrapolated to other reporter-analyte systems that depend on a binding equilibrium process.

Solvent and catalyst-free synthesis, corrosion protection, thermodynamic, MDS and DFT calculation of two environmentally friendly inhibitors: Bis-phosphonic acids

Solvent and catalyst-free synthesis of two bis-phosphonic acids were realized adopting one-pot reaction of 2,6-bis (hydroxymethyl)-4-methoxyphenol or 4-chloro- 2,6-bis (hydroxymethyl) phenol with trialkyl phosphite. Their structures were confirmed by H-1, C-13, P-31 NMR and IR spectroscopies. The molecular structures have been optimized using DFT, and the related calculated vibrational frequencies and NMR shift confirm the proposed structures. Chemical and electrochemical tests evaluated the inhibitive capabilities on the XC48 steel corrosion against 1 M HCl. The weight loss (chemical one) shows that the adsorption on the XC48 steel surface obeys to Langmuir isotherm, while the polarization measurements suggest that the inhibition process is mixt, the results of Electrochemical Impedance Spectroscopy (EIS) prove an increase of the inhibition efficiency with the increase of inhibitor concentrations. The surface topographies were analyzed by the Atomic Force Microscopy (AFM). The Density Functional Theory (DFT) with B3LYP as correlation function and 6-31G (p, d) as basis sets were used to determine some theoretical physic-chemical parameters affecting the corrosion inhibition and on the other hand the DFT develop the Frontier Molecular Orbitals (FMOs) and the Molecular Electrostatic Potentials (MEP) and through a discussion was made about their relationship with the inhibition of the corrosion. At the end, Molecular Dynamics Simulations (MDS) based on Monte-Carlo calculations were accomplished to simulate the interface configuration between the inhibitor molecules and Fe (110)/H2O.

Microwave-assisted extraction, partial purification and biological activity in vitro of polysaccharides from bladder-wrack (Fucus vesiculosus) by using deep eutectic solvents

Based on natural deep eutectic solvents (DESs), microwave-assisted green extraction was applied for production of polysaccharides from bladder-wrack (Fucus vesiculosus). In this study, nine different combinations of deep eutectic solvents were evaluated for extraction of polysaccharides from bladder-wrack, and the results showed that DES system composed of choline chloride and 1,4-butanediol with molar ratio of 1:5 possessed the optimal extraction efficiency for polysaccharides. A three-level and four-variable Box-Behnken design (BBD), a specific design of response surface methodology (RSM), was used to determine the optimum extraction conditions for the maximum yields of polysaccharides from bladder-wrack by using DESs. The maximum yields of polysaccharides attained 116.33 mg/g within DES water content of 32%, extraction time of 35 min, extraction temperature of 168 degrees C and solid-liquid ratio of 39 mg/mL. After partial separation and purification of the polysaccharides extracted by DESs, antioxidant activity and anticancer activity in vitro were evaluated. The results revealed that polysaccharides extracted from bladder-wrack exhibited excellent antioxidant activities in vitro including DPPH and ABTS radical-scavenging activity. For human cervical cancer HeLa cells, the polysaccharides possessed a strong inhibition effect on the growth rate. So these results indicate that deep eutectic solvent, as an environmentally-friendly solvent, can be applied to extract polysaccharides from multifarious plant materials.

Deep eutectic solvent assisted synthesis of carbon dots using Sophora flavescens Aiton modified with polyethyleneimine: Application in myricetin sensing and cell imaging

Here, an efficient method for synthesizing carbon dots (CDs) using a deep eutectic solvent (DES) was developed. To investigate the influence of different DESs on the quantum yield of CDs, different hydrogen-bonding acceptors (HBAs) and hydrogen-bonding donors (HBDs) were used to synthesize the DES and prepare CDs. Using Sophora flavescens Aiton as precursor, CDs were prepared using choline chloride (ChCl)/urea based DES as reaction media and doping agent in the presence of water. The CDs showed strong blue fluorescence and were further modified with polyethyleneimine (CDs@PEI). The fluorescence intensity of CDs@PEI was selectively quenched by myricetin with a limit of detection (LOD) of 10 nM. Furthermore, CDs@PEI was used to analyze myricetin in the extracts that were fluorescent by DES with satisfactory performance of Abelmoschus manihot (Linn.) Medicus flowers, vine teas and blueberries. Finally, the bio-imaging application of CDs@PEI was tested and the results confirmed its potential application in bio-imaging.
