Assessment of Distinct Electrophysiological Parameters in Rectal Biopsies for the Choice of the Best Diagnosis/Prognosis Biomarkers for Cystic Fibrosis

Most cases of Cystic Fibrosis (CF) are diagnosed early in life. However, people with atypical CF forms pose diagnosis dilemmas, requiring laboratory support for diagnosis confirmation/exclusion. Ex vivo analysis of fresh rectal biopsies by Ussing chamber has been the best discriminant biomarker for CF diagnosis/prognosis so far. Here we aimed to evaluate different electrophysiological parameters from Ussing chamber analysis of rectal biopsies from people with CF (PwCF) to establish the one with highest correlations with clinical features as the best CF diagnosis/prognosis biomarker. We analyzed measurements of CFTR-mediated Cl- secretion in rectal biopsies from 143 individuals (similar to 592 biopsies), the largest cohort so far analyzed by this approach. New parameters were analyzed and compared with the previous biomarker, i.e., the IBMX (I)/Forskolin (F)/Carbachol (C)-stimulated short-circuit current (I'(sc-I/F/C)). Correlations with clinical features showed that the best parameter corresponded to voltage measurements of the I/F + (I/F/CCH) response (VI/F+I/F/C), with higher correlations vs. I'(sc-I/F/C) for: sweat chloride (59 vs. 52%), fecal elastase (69 vs. 55%) and lung function, measured by FEV1 (27 vs. 20%). Altogether data show that VI/F+I/F/C is the most sensitive, reproducible, and robust predictive biomarker for CF diagnosis/prognosis effectively discriminating classical, atypical CF and non-CF groups.

Jute fiber based micro-mesoporous carbon: A biomass derived anode material with high-performance for lithium-ion batteries

Jute fiber has been used as carbon precursor to prepare micro-mesoporous carbon material applying as anode materials for lithium ion battery. The main step was to use different quantity of zinc chloride as an activator under the carbonization at high temperature in the air atmosphere, and then an activated carbon material with prosper porosity and high specific surface area of 1028.614 m(2) g(-1) was obtained and named JFAC. The obtained micro-mesoporous structure benefits the lithium transfer in the active anode material. The impact of JFACs on the electrochemical performance was evaluated, showing its outstanding cycle stability and specific capacity with 742.7 mA h g(-1) after 100 cycles at 0.2C. A discussion of the quantity of zinc chloride activator was exhibited and this method finally shows the high efficiency of zinc chloride for the activation of biomass carbon materials.

Application of semibatch technology on the investigation of homogeneously catalyzed consecutive and parallel-consecutive liquid-phase reactions: Kinetic measurements and modelling

Experimental measurements of the reaction kinetics of complex consecutive and parallel-consecutive reactions is a challenge, because the reaction rates of the sequence are often very different, the primary reactions being much more rapid while the secondary and tertiary reactions might be much slower requiring very long kinetic experiments. An approach to surmount this dilemma is proposed for homogeneously catalyzed liquid-phase reactions by adding the catalyst gradually into the reaction mixture: in this way the primary reactions are slowed down but the secondary and tertiary reactions are accelerated. A mathematical model for this approach was developed and complex reaction systems were simulated numerically in the Damkohler space. The applicability of the approach was illustrated with experimental data obtained for the formation of mono- and diesters from carboxylic acids and dialcohols in the presence of homogeneous strong acid catalysts. Acetic acid and ethylene glycol were used as reagents in the experimental work and aqueous hydrogen chloride was the homogeneous catalyst. Rate equations for this reaction systems were derived based on molecular mechanisms and the kinetic parameters in the rate equations were estimated with regression analysis. Simulation of the esterification model illustrated the benefits of the proposed experimental semibatch approach for complex reaction systems. (C) 2021 Elsevier Ltd. All rights reserved.

Influence of dry-wet ratio on properties and microstructure of concrete under sulfate attack

This experimental study aims to determine the effect of dry-wet ratio on properties and microstructure of concrete under sulfate attack. Under the condition of oven drying, four different dry-wet time ratios were designed: 1:1, 3:1, 5:1, and 7:1. In this paper, the deterioration law of concrete under sulfate attack was investigated through compressive strength, splitting tensile strength and relative dynamic elastic modulus (RDEM). Moreover, microstructure and phase composition were investigated by SEM and XRD respectively, and evolution of the pore characteristics of the concrete were examined by MIP. The results show that when the dry-wet ratio is 3:1, sulfate deteriorate concrete the most. Wetting time affects chemical attack strength of sulfate and the capability of concrete to accommodate the expansion phase, the drying process only deteriorate the concrete in the middle and late stages of erosion. The generation and filling of micro-voids are the main reasons for the evolution of concrete performance, in this process, concrete has experienced fatigue damage of steady state-unsteady state-new steady state.

One-Step Activation of Anode Materials from Spent Lithium-Ion Batteries as High-Performance Electrodes for Capacitive Deionization

Mesophase microporous carbon spheres (MMCS), are the anode materials of spent lithium-ion batteries (LIB), existing in large amounts on the earth that result in resource wastes and ecological pollution. In order to utilize the above waste resources, a new idea of recycling scrapped LIB anode materials was exploited to apply for capacitive deionization (CDI). Herein, the activated microporous carbon spheres (AMCS) were synthesized by a one-step KOH activation of mesophase microporous carbon spheres (MMCS). By controlling the weight ratios of KOH to MMCS, the fabricated AMCS with the optimal specific surface area of 2626 m(2) g(-1) and the pore volume of 0.98 cm(3) g(-1) were fabricated. The AMCS3-1 with a weight ratio of KOH to MMCS of 3 : 1 exhibits higher specific capacitance (196.9 F g(-1)) and lower charge transfer resistance. Importantly, the AMCS3-1 electrode demonstrates excellent electrosorption capacity of 12.73 mg g(-1) and fast salt adsorption rate of 2.64 mg g(-1) min(-1) at 1.2 V. In addition, the excellent repeatability over 50 regeneration cycles could be obtained for AMCS3-1 electrode compared with commercial activated carbon electrode. The results reveal that the AMCS3-1 is a promising candidate as high-performance electrodes for CDI. The strategy of recycling MMCS from waste LIB anode materials for CDI is desirable, which displays great potential in the removal of sodium chloride (NaCl).

Blend membranes based on N1-alkyl-substituted imidazolium functionalized polymers and aromatic polyethers: influence of N1-alkyl substituent on properties and alkaline stability

N1-alkyl (octyl and dodecyl)-substituted imidazolium-based PVBC homopolymers have been synthesized via N-quaternization reaction of N1-alkyl imidazole and PVBC precursor homopolymer bearing reactive benzyl chloride moieties. Due to their poor film forming properties and water solubility, these homopolymers were blended with aromatic polyethers bearing main chain pyridine units at different compositions in order to study the effect of alkyl chain length on morphology, water uptake, swelling ability and chemical stability of the prepared membranes. The B2 blend membrane with the highest N1-dodecyl-substituted imidazolium PVBC content (65 wt%) exhibited the highest water uptake (54%) despite its lower IEC value compared to the corresponding one containing N1-octyl-substituted imidazolium PVBC, low swelling ratio and a phase separated morphology. Evaluation of the chemical stability in 3.6 M KOH solution at 80 degrees C for 7 days revealed the degradation of imidazolium via ring opening, as evidenced by ATR-FT-IR spectroscopy. Therefore, new blends having as second constituent, the N1-alkyl-substituted imidazolium functionalized poly(PVBC-co-AA(20)) copolymers containing acrylic acid units were fabricated targeting to the improvement of chemical stability via ionic cross linking. The prepared D1 and D2 blend membranes containing 60 and 65 wt% dodecyl-imidazolium functionalized poly(PVBC-co-AA(20)) copolymer content, respectively, were flexible, exhibited moderate IECs (1.47-1.60 meq/g) and sufficient water uptakes (up to 30%). D2 blend membrane showed excellent chemical stability after testing in 3.6 M KOH solution at 80 degrees C for 30 days, as confirmed by ATR-FT-IR spectroscopy and TGA analysis. The excellent chemical stability can probably be attributed to the steric hindrance effect of N1 dodecyl substituent which effectively protects the C2 position of imidazolium from hydroxide attack as well as to the formation of a dense, ionic cross-linked structure that hinders hydroxide penetration.

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.

Lithium as a possible therapeutic strategy for Cornelia de Lange syndrome

Cornelia de Lange Syndrome (CdLS) is a rare developmental disorder affecting a multitude of organs including the central nervous system, inducing a variable neurodevelopmental delay. CdLS malformations derive from the deregulation of developmental pathways, inclusive of the canonical WNT pathway. We have evaluated MRI anomalies and behavioral and neurological clinical manifestations in CdLS patients. Importantly, we observed in our cohort a significant association between behavioral disturbance and structural abnormalities in brain structures of hindbrain embryonic origin. Considering the cumulative evidence on the cohesin-WNT-hindbrain shaping cascade, we have explored possible ameliorative effects of chemical activation of the canonical WNT pathway with lithium chloride in different models: (I) Drosophila melanogaster CdLS model showing a significant rescue of mushroom bodies morphology in the adult flies; (II) mouse neural stem cells restoring physiological levels in proliferation rate and differentiation capabilities toward the neuronal lineage; (III) lymphoblastoid cell lines from CdLS patients and healthy donors restoring cellular proliferation rate and inducing the expression of CyclinD1. This work supports a role for WNT-pathway regulation of CdLS brain and behavioral abnormalities and a consistent phenotype rescue by lithium in experimental models.

Comparative study of embedded functionalised MWCNTs and GO in Ultrafiltration (UF) PVC membrane: interaction mechanisms and performance

This work presents the development of polyvinyl chloride/functionalised multi-carbon nanotube (PVC/F-MWCNT) membranes and PVC/graphene oxide (PVC/GO) membranes for the improved removal of chemical oxygen demand (COD) from actual petroleum wastewater. Also, this work for the first time presents the proposed interaction mechanism between the contents of PVC/GO and PVC/F-MWCNT membranes as well as the interaction mechanism of each composite membrane with water molecules. The effect of both F-MWCNT and GO content on the characteristics and performance of the PVC/F-MWCNT membrane and PVC/GO membrane were studied. Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM), contact angle (CA), differential scanning calorimetry (DSC), porosity and tensile strength were used to examine the properties of F-MWCNT, GO, PVC/F-MWCNT and PVC/GO membranes. The composite membranes’ performance was studied by measuring the rejection of chemical oxygen demand (COD) and mass flux. It was found that F-MWCNTs and GO played significant roles in the membranes’ structural morphology. A significant improvement was obtained in the CA, porosity and tensile strength of the membranes by embedding the PVC casting solution with 0.12 wt% of each F-MWCNTand GO. The PVC/F-MWCNTs membrane showed higher performance in term of mass flux and COD rejection that reached 88.9%, which makes using a PVC/F-MWCNTs membrane preferable to remove COD from petroleum wastewater.
