A new ophthalmic formulation containing antiseptics and dexpanthenol: In vitro antimicrobial activity and effects on corneal and conjunctival epithelial cells

Antibiotic resistance is increasing even in ocular pathogens, therefore the interest towards antiseptics in Ophthalmology is growing. The aim of this study was to analyze the in vitro antimicrobial efficacy and the in vitro effects of an ophthalmic formulation containing hexamidine diisethionate 0.05%, polyhexamethylene biguanide (PHMB) 0.0001% disodium edetate (EDTA) 0.01%, dexpanthenol 5% and polyvinyl alcohol 1.25% (Keratosept, Bruschettini, Genova, Italy) on cultured human corneal and conjunctival cells. The in vitro antimicrobial activity was tested on Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Streptococcus pneumoniae, Streptococcus pyogenes and Streptococcus mitis. For each microbial strain 10 mu L of a 0.5 MacFarland standardized bacterial inoculum were incubated at 25 degrees C with 100 mu L of ophthalmic solution for up to 6 h. After different periods of time, samples were inoculated on blood agar with 5% sheep blood. Moreover, a 0.5 MacFarland bacterial inoculum was seeded in triplicate on Mueller-Hinton Agar or on Mueller-Hinton Fastidious Agar; then a cellulose disc soaked with 50 mu L of ophthalmic solution was applied on the surface of agar and plates were incubated for 18 h at 37 degrees C, in order to evaluate the inhibition of bacterial growth around the disc. Human corneal and conjunctival epithelial cells in vitro were incubated for 5, 10 and 15 min with Keratosept or its components. The cytotoxicity was assessed through the release of cytoplasmic enzyme lactate dehydrogenase (LDH) into the medium immediately after exposure to the drugs; the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed to evaluate the metabolic cell activity. Our results show that Keratosept ophthalmic solution gave an average logarithmic (log) reduction of bacterial load of 2.14 +/- 0.35 within 6 h of exposure (p-value < 0.05 versus control saline solution). On agar plates, all microbial strains, excluding P. Aeruginosa, showed an inhibition zone of growth around the Keratosept-soaked discs. Keratosept and its components after 5 and 10 min did not show any cytotoxic effect on cultured corneal and conjunctival cells, and only after 15 min a significant reduction of cell viability and an increase of cytotoxicity compared to control (vehicle) was seen; dexpanthenol 5% and polyvinyl alcohol accelerated the wounding of corneal cells in vitro. In conclusion, Keratosept showed good antimicrobial activity on the tested strains; the ophthalmic solution and its components were safe and non-toxic for the corneal and conjunctival epithelial cells for 5 and 10 min at the concentrations analyzed, and dexpanthenol 5% and polyvinyl alcohol promoted the wounding of corneal cells.

Synthesis, Modification, and Characterization of CuO/ZnO/ZrO2 Mixed Metal Oxide Catalysts for CO2/H-2 Conversion

CuO/ZnO/ZrO2 catalyst systems were synthesized in different ways and comprehensively characterized in order to study synthesis-to-property relations. A series of catalyst samples was prepared by coprecipitation, one-pot synthesis, and wet impregnation. The coprecipitation of multicomponent precipitates is usually a preliminary stage for preparation of mixed oxide catalysts. Cetyltrimethylammonium bromide (CTAB) was used in the surfactant-supported coprecipitation to improve the structural or textural characteristics of the catalytic samples. In the one-pot synthesis, all necessary components are simultaneously converted by evaporation from solutions into solids. During the wet impregnation, zirconium hydroxide is loaded with metal salts. After thermal treatment, all samples formed pure metal oxide forms, which was confirmed by XRD. The specific surface area of the investigated samples and their porous texture were determined by nitrogen adsorption. The reducibility of metal oxides and the kind of CuO phase was characterized by temperature-programmed reduction (TPR), and the surface acid properties by temperature-programmed ammonia desorption (TPAD). The CuO/ZnO/ZrO2 sample with the highest amount of strong acid sites is characterized by the formation of large CuO particles combined with the worst reducibility so that potentially catalytic active Cu/CuO pairs can be formed. One catalyst system was further characterized by in situ diffuse reflection Fourier transform infrared spectroscopy (DRIFTS) to identify surface intermediate species, which may occur during the conversion of CO2/H-2 to methanol.

Vapor-liquid equilibria of HFC-161+HFC-32+DMF ternary mixture for low-grade heat driven absorption refrigeration system

Ternary mixture of fluoroethane (HFC-161) + difluoromethane (HFC-32) + N,N-dimethylformamide (DMF) is a promising working fluid for absorption refrigeration system which is an important energy saving technology receiving more and more attention. Investigation on vapor-liquid equilibrium (VLE) is necessary for further study and the application in absorption system of the ternary mixture. Therefore, an experimental system with continuous vapor-phase circulation is set up, measuring VLE data within temperature range of 283.15 to 323.15 K. The experimental data is correlated with Wilson and NRTL models, and BP-ANN method, respectively. The calculating data of Wilson model has the largest relative deviation of 5.14% and average relative deviation of 2.65% for vapor pressure, being the best one. The deviation of molar fraction data obtained with BP-ANN model has the best average relative deviation 3.07%. However, NRTL model provides a smooth predicted surface. The correlated parameters of the three models are given.

LncRNA XIST protects podocyte from high glucose-induced cell injury in diabetic nephropathy by sponging miR-30 and regulating AVEN expression

Diabetic nephropathy (DN) is one of the most important complications of diabetes mellitus. Thus, it is urgent to develop a novel diagnosis or therapeutic strategy that could suspend DN progression. Moreover, there is increasing evidence demonstrating that long non-coding RNA (lncRNA) acts as critical players in regulating autophagy and are involved in DN. We demonstrated that lncRNA X-inactive specific transcript (XIST) was downregulated in high glucose (HG) treated podocytes, accompanied by increased apoptosis of podocytes. Overexpression of XIST significantly reduced the apoptosis and promoted the number of viable cells of podocyte under HG treatment. Prediction by Targets can and dual-luciferase reporter assay revealed the interaction between miR-30 and XIST and AVEN. Further WB (Western Blot), MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), and flow cytometry confirmed that XIST could reverse the expression of AVEN and ameliorate HG-induced apoptosis. In conclusion, our research revealed that XIST plays a protective effect on podocyte injury induced by HG through miR-30/AVEN axis.

Study on the characteristics of charging/discharging processes in three-phase energy storage coupling in solar air conditioning system

A new combination system of three-phase energy storage and solar absorption refrigeration has been developed in this paper. The operation process of LiBr-H2O three-phase energy storage system is described in detail. Thermodynamic analysis models of charging/discharging processes based on the absorption principle are established in order to understand the dynamic characteristics of three-phase energy storage and release processes. The dynamic simulations of charging/discharging processes are carried out by using MATLAB. The influences of operation parameters on the characteristic parameters of three-phase charging/discharging are analyzed, and the performance evaluation indexes of three-phase energy storage system are obtained. The simulation results showed that the lower initial concentration of LiBr-H2O solution, the smaller mass flow rate of LiBr-H2O sprayed on the heat exchanger in the energy storage tank and the higher heat conductance of the heat exchanger (KA) result in the higher energy storage efficiency and energy storage density. The smaller mass flow rates of LiBr-H2O and the cooling water can make the more stable discharging process with longer cooling time. The research results can provide theoretical guidance for further improving and optimizing the operation performance of three-phase energy storage system coupling in solar air conditioning.

Microbial reduction of bromate: current status and prospects

Bromate is a disinfection byproduct (DBP) that forms during the ozonation of bromide-containing natural water, which may cause health risks to humans. In this review, we provide an overview of the mechanism of bromate formation, microbial communities and bioreactors that are responsible for bromate reduction. Bromate can be formed through two pathways of bromide oxidation by ozone or by OH, and it can be removed by biological approaches. Members belonging to phyla of Spirochaetes, Proteobacteria, Firmicutes, Actinobacteria, Clostridium, Deinococcus-Thermus and Bacteroidetes have been identified as capable of reducing bromate to bromide. Multiple configurations of biofilm bioreactors have been employed to cultivate microbial communities to perform bromate removal. The rapid development of multiomics has and will continue to accelerate the elucidation of the mechanisms involved in bromate and other DBP conversions, as well as the interaction patterns among different bacterial subdivisions in the bioremoval of DBPs.

Salt and bile salt accelerate self-assembly behavior of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) probed by curcumin fluorescence

Understanding self-assembly aspects of block copolymers is of great importance due to their utility in a wide range of applications whether in chemistry, pharmacy, or medicine. In this work, properties of poly(ethylene oxide) -block- poly(propylene oxide) -block- poly(ethylene oxide) (F108) are studied in solution using fluorescence technique and curcumin as the molecular probe. Fluorescence of curcumin has been tracked in solutions of different concentrations of F108. The CMC (critical micellar concentration) and CMT (critical micellar temperature) have been found to be 23.2 mu M and 35 degrees C respectively. First time curcumin fluorescence-based method has been proven to be useful to estimate CMT. Furthermore, fluorescence quenching technique using hydrophobic cetyl pyridinium bromide and hydrophilic KI quenchers has established the position of curcumin is located near the hydrophobic pocket of Stern-layer of F108 micelle. New insight on effect of ionic strength and bile salt on the CMC and CMT values of F108 is evaluated through curcumin probing. CMC has decreased with the increase in the concentration of the three salts except for NaC. The effect has been arranged in decreasing order as follows: NaDC > NaCl > NaC. On the other hand, the effect of the three salts on the CMT of F108 has been found to be less remarkable, with a 1-fold decrease for NaCl and NaDC and almost no change for NaC.

Ivermectin induces autophagy-mediated cell death through the AKT/mTOR signaling pathway in glioma cells

Glioma is one of the most common types of primary brain tumors. Ivermectin (IVM), a broad-spectrum antiparasitic drug, has been identified as a novel anticancer agent due to its inhibitory effects on the proliferation of glioma cells in vitro and in vivo. However, the ability of IVM to induce autophagy and its role in glioma cell death remains unclear. The main objective of the present study was to explore autophagy induced by IVM in glioma U251 and C6 cells, and the deep underlying molecular mechanisms. In addition, we examined the effects of autophagy on apoptosis in glioma cells. In the present study, transmission electronmicroscopy (TEM), immunofluorescence, Western blot and immunohistochemistry were used to evaluate autophagy activated by IVM. Cell viability was measured by 3-(4,5-dimethylthiazol2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and colony formation assay. The apoptosis rate was detected by flow cytometry and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL). Meanwhile, autophagy inhibition was achieved by using chloroquine (CQ). U251-derived xenografts were established for examination of IVM-induced autophagy on glioma in vivo. Taken together, the results of the present study showed that autophagy induced by IVM has a protective effect on cell apoptosis in vitro and in vivo. Mechanistically, IVM induced autophagy through AKT/mTOR signaling and induced energy impairment. Our findings show that IVM is a promising anticancer agent and may be a potential effective treatment for glioma cancers.

A new series of thiazolyl pyrazoline derivatives linked to benzo[1,3]dioxole moiety: Synthesis and evaluation of antimicrobial and anti-proliferative activities

2-(5-(Benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-1-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-substituted phenyl)thiazole (7) and thiazole derivatives (9) were synthesized via reaction of 4,5-dihydro-1H-pyrazoles (5a,b) with substituted phenacyl bromide and a number of alpha-halo-compounds respectively. Also, (E)-2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-1-yl)-4,5 dihydro-1H-pyrazol-1-yl)-4-methyl-5-(substituted phenyldiazenyl)thiazole (11) were prepared through reactions of carbothioamide (5a,b) with hydrazonoyl halides. In addition, thioamides (5a-b) were used as starting materials for preparation of thiazoles (12a-b) and benzylidene thiazoles (13a-b). Most of synthesized compounds show interesting biological properties as antimicrobial and antiproliferative activities, the results of minimum inhibitory concentration showed that pyrazole derivative 7c (MIC: 0.23 mg/mL) showed better results when compared with 11c and 12a (MIC: 0.1-0.125 mg/mL) as obtained from their MIC values. On the other hand, 2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-chlorophenyl) thiazole (7c) can be considered as the most promising anti-proliferative agent against HCT-116 cancer cells owing to its notable inhibitory effect on HCT-116 cells with an IC50 value of 6.19 mu M.
