Mechanism-Based Personalized Medicine for Cystic Fibrosis by Suppressing Pseudo Exon Inclusion

Cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that compromise its chloride channel activity. Here, we present a therapeutic strategy to ameliorate RNA splicing deficiency of CFTR with a small molecule. The 3,849 + 10 kb C>T is the most common splicing mutation in CF, creating a pseudo exon with premature stop codon. We reveal that the 3,849 + 10 kb C>T-induced CFTR pseudo exon is regulated by phosphorylation of serine/arginine-rich splicing factors, and their functional inhibition by a CDC-like kinase inhibitor restores normal splicing of CFTR. Subsequent screening of our focused chemical library identified CaNDY as a rectifier of the aberrant splicing. CaNDY treatment restored normal splicing of CFTR with the 3,849 + 10 kb C>T in CF patient cells and functional CFTR protein expression in the CF model cells. Our findings open the door for mechanism-based personalized medicine for pseudo-exon-type genetic diseases.

Using layered double hydroxides and anion exchange resin to improve the mechanical properties and chloride binding capacity of cement mortars

Chloride-induced corrosion results in the deterioration of concrete structures. To resolve this issue, two types of synthetic layered double hydroxides (LDHs) 2D nanoflakes based on CaFe-NO3 and CaFeAl-NO3 and a strongly basic anion exchange resin (SBAER) were developed for removing chloride ions from simulated sea sand (SSS) mortars. We investigated the combined effect of SSS mortars blended with chloride adsorbents using the response surface methodology (RSM). A Box-Behnken Design (BBD) was used to discuss the independent variables (CaFe-NO3 LDHs, CaFeAl-NO3 LDHs, and SBAER) and evaluate the response of compressive strength and free chloride content concerning admixture content. Experimental results showed that the free chloride content of the samples decreased upon the addition of LDHs and SBAER due to a synergistic effect, which resulted in the formation of LDHs-Cl, [N+(CH3)(3)Cl], Friedel’s salt (FS), and Kuzel’s salt (KS). The optimal range of the admixture content was determined to be 0.3-0.6 wt% CaFe-NO3 LDHs, 0.2-0.5 wt% CaFeAl-NO3 LDHs, and 0.2-0.5 wt% SBAER. In conclusion, LDHs and SBAER exhibited excellent chloride binding capacity, which makes them promising candidates for use as high-efficiency and stable chloride composite adsorbents in marine concrete.

Enhancement of the corrosion inhibition of carbon fibre via the effect of the chloride ions on its anodic corrosion

The results of this study showed the beneficial effect of chloride ion to enhance the corrosion inhibition and prevent direct oxidation of carbon fibres under anodic polarization. The corrosion rate of carbon fibre sharply decreased after introducing chloride ions. Uniaxial tensile test performed after the simulated ICCP tests showed that the tensile strength of the carbon fibre bundles was higher when the electrolyte contained chloride ions. The application of carbon fibre as the anode material is found to be particularly well suited for coastal reinforced concrete structures. (C) 2020 Elsevier Ltd. All rights reserved.

Zeta potential changing nanoemulsions based on a simple zwitterion

Hypothesis: Simple zwitterions used as auxiliary agents might have the potential to change the zeta potential of oil-in-water (o/w) nanoemulsions on the mucosa. Experiments: The zwitterion phosphorylated tyramine (p-Tyr) was synthesized by phosphorylation of Boc-tyramine (Boc-Tyr) using phosphoryl chloride (POCl3). It was incorporated with 2% (m/v) in a self emulsifying lipophilic phase comprising Captex 35, Cremophor EL, Capmul MCM and glycerol 85 at a ratio of 30:30:30:10 v/v. Phosphate release and resulting change in zeta potential were evaluated by incubating p-Tyr containing nanoemulsion with isolated intestinal alkaline phosphatase (AP). Mucus permeating behavior was evaluated across mucus obtained from porcine small intestinal mucosa. Subsequently, cellular uptake studies were accomplished on Caco-2 cells. Findings: The p-Tyr loaded nanoemulsion exhibited a mean droplet size of 43 1.7 nm and zeta potential of -8.40 mV. Phosphate moieties were rapidly cleaved from p-Tyr loaded nanoemulsions after incubation with isolated AP resulting in a shift in zeta potential from -8.40 mV to +1.2 mV. p-Tyr loaded nanoemulsion revealed a significantly (p <= 0.001) improved mucus permeation compared to the same nanoemulsion having been pre-treated with AP. Cellular uptake of the zeta potential changing oily droplets was 2.4-fold improved. Phosphorylated zwitterions seem to be an alternative to cationic surfactants and considered as promising auxiliary agents for zeta potential changing nanoemulsions. (C) 2020 The Authors.

Performance of engineered cementitious composites incorporating crumb rubber as aggregate

Engineered cementitious composites (ECC) are a special type of fiber reinforced cementitious composites that are reinforced with Polyvinyl alcohol fibers. ECC exhibits outstanding deformable and durability properties. However, the limited availability and high cost of silica sand required for the production of ECC have limited its widespread applications. Hence, it is imminent to find materials that can be used as alternatives to partially or totally replace the silica sand in ECC. This paper presents the results from a feasibility study on the use of crumb rubber which is a recycled material as aggregates in ECC mixtures. In this study, crumb rubber was incorporated to replace the silica sand up to 100% and the influence on the performance evaluated. The study showed that the incorporation of crumb rubber causes a reduction in the strength of the ECC, though these ECC qualify to be used in the structural application. Also, the ductility and the durability of ECC incorporating crumb rubber was improved with the incorporation of crumb rubber. The mid-span deflection and tensile strain of ECC incorporating only crumb rubber as aggregate were found to be 96.8% and 110.2%, respectively higher than the ECC made with only silica sand as aggregate. Also, the incorporation of crumb rubber as aggregate into the mixtures resulted in a reduction in the permeability properties of the composites. The porosity, water absorption and chloride penetration of ECC were reduced by 33%, 36% and 12%, respectively when crumb rubber was used as a 100% replacement of silica sand. (C) 2020 Elsevier Ltd.

A review on the synthesis of fully aromatic polyamide reverse osmosis membranes

Reverse osmosis (RO) membranes have been used for desalination for over 40 years. This review focuses on the lab-scale synthesis of fully aromatic polyamide layers used to create RO membranes using the interfacial polymerization (IP) process between an amine monomer, m-phenylenediamine (MPD), and an acyl chloride monomer, trimesoyl chloride (TMC). This review extensively covers the numerous lab-scale synthesis protocols used in research labs and proposed mechanisms and kinetics for synthesizing these fully aromatic polyamide layers using IP. Emphasis is placed on the support membrane used and the reaction conditions such as monomer concentration, solution volume, aqueous solution soaking time, reaction time, reaction temperature, and the use of nonreactive additives in the reaction solution. The effect of processing techniques for removing the aqueous solution and for post-reaction cross-linking are discussed. These variables are compared by investigating their effect on the membrane desalination performance. The numerous methods used to characterize the polyamide layers are reviewed. The synthesis of fully aromatic polyamide layers on hollow fiber membranes is briefly discussed. The goal of this review is to discuss the numerous synthesis parameters in reported lab-scale studies for control membranes, which may help researchers to synthesize and improve RO membranes more effectively.

An Integrated HOCl-Producing E-Scaffold Is Active against Monomicrobial and Polymicrobial Biofilms

Oxidizing agents like hypochlorous acid (HOCl) have antimicrobial activity. We developed an integrated electrochemical scaffold, or e-scaffold, that delivers a continuous low dose of HOCl aimed at targeting microbial biofilms without exceeding concentrations toxic to humans as a prototype of a device being developed to treat wound infections in humans. In this work, we tested the device against 33 isolates of bacteria (including isolates with acquired antibiotic resistance) grown as in vitro biofilms alongside 12 combinations of dual-species in vitro biofilms. Biofilms were grown on the bottoms of 12-well plates for 24 h. An integrated e-scaffold was placed atop each biofilm and polarized at 1.5 V for 1, 2, or 4 h. HOCl was produced electrochemically by oxidizing chloride ions (Cl-) in solution to chlorine (Cl-2); dissolved Cl-2, spontaneously dissociates in water to produce HOCl. The cumulative concentration of HOCl produced at the working electrode in each well was estimated to be 7.89, 13.46, and 29.50 mM after 1, 2, and 4 h of polarization, respectively. Four hours of polarization caused an average reduction of 6.13 log(10) CFU/cm(2) (+/- 1.99 log(10) CFU/cm(2)) of viable cell counts of monospecies biofilms and 5.53 log(10) CFU/cm(2) (+/- 2.31 log(10) CFU/cm(2)) for the 12 dual-species biofilms studied. The described integrated e-scaffold reduces viable bacterial cell counts in biofilms formed by an array of antibiotic-susceptible and -resistant bacteria alone and in combination.

Mechanical and durability properties of recycled aggregate concrete produced from recycled and natural aggregate blended based on the Densified Mixture Design Algorithm method

The aim of this study was to reuse recycled concrete aggregates for concrete production by using the Densified Mixture Design Algorithm (DMDA) method for blended aggregates and mixing design based on the evaluation of characteristics of recycled aggregate concrete (RAC). Recycled coarse aggregate (RCA) was used to replace 30%, 40%, and 50% of the natural coarse aggregate (NCA), respectively, by volume in the samples, and the fine aggregate was a combination of 70% natural fine aggregate (NFA) and 30% recycled fine aggregate (RFA) by volume. A series of tests, including compressive strength, splitting tensile strength, ultrasonic pulse velocity (UPV), electrical surface resistivity (ESR), thermal conductivity (TC), water absorption, and the rapid chloride penetration test (RCPT) were conducted in accordance with the relevant standards. The results illustrated that blending aggregates following to DMDA method suggested an optimum proportion of RCA level which exhibited with highest volume of aggregate per unit volume of combination of RCA and NCA. The results revealed 40% RCA content as the optimum replacement level. Furthermore, the 40% RCA concrete mix exhibited good hardening properties in terms of being only slightly below the 30% RCA mix and significantly higher than the 50% RCA mix. All of the RAC mixtures designed by DMDA method with low cement consumption exhibited good strength development and good durability through 120 days of curing.

On the ligand exchange, redox, and disproportionation processes of tetrachloroaurate in the presence of a pyridine derivative

The potential applications of Au-I precursors and pyridine derivatives for shape-directed nanoparticle growth has provided an impetus for the present study of the chemistry of tetrachloroaurate (AuCl4-) in the presence of 4-methoxypyridine (Py-/). Electrochemical experiments show that the addition of Py-/ to AuCl4-leads to the co-existence of both Au-III and Au-I species as evidenced by the observation of two reduction events in the cyclic voltammetry. Kinetic analyses have been used to show that multiple ligand exchange processes occur over the course of several minutes and result in the formation of a Au-III species with two Py-/ and a variable number of chloro and hydroxo ligands in the inner sphere. The kinetics of the initial Py-/ substitution reaction are shown to follow a modified form of the two-term rate law typical of square planar complexes. The observation of a slow, but spontaneous, conversion of Au-III species to Au-I species has been explained by estimating the standard reduction potential for the pyridine/pyridine-N-oxide redox couple and demonstrating that it can drive a galvanic reaction with the AuPy/Cl-2(q)(OH)(2-q)(+)/AuPy2/+ redox couple. The previously reported tendency of this system to form highly anisotropic gold nanoparticles on conductive metal oxide electrodes is explained by a thermodynamic analysis of the disproportionation reaction of AuPy2/+ (C) 2020 Elsevier Ltd.
