Antifouling, antibacterial and non-cytotoxic transparent cellulose membrane with grafted zwitterion and quaternary ammonium copolymers

Copolymer brushes with different ratios of sulfobetaine methacrylate (SBMA) and [2-(Acryloyloxy)ethyl] trimethylammonium chloride (DAC) were grafted from transparent cellulose membrane (CM) via surface-initiated atom transfer radical polymerization (SI-ATRP) method for improving its antifouling and antibacterial performance. Surface concentrated copolymer grafting on the cellulose membranes can be obtained without significantly sacrificing the transparency and mechanical properties. The zwitterionic PSBMA chains of the copolymers can lead to an extremely hydrophilic surface with significantly reduced non-specific protein adsorption and bacterial attachment, therefore, leading to satisfying antifouling and antibacterial property. While the PDAC chains of the copolymers improved antibacterial performance against both Gram-positive and Gram-negative bacteria due to the presence of quaternary ammonium groups, the PDAC modified CM (CM-1) possessed best antibacterial performance, reaching to 95.1 % against S. aureus and 90.5 % against E. coli, respectively. More importantly, the biocompatibility of all grafted CM was retained, leading to over 100 % cell viability.

Recent advances in catalytic silylation of hydroxyl-bearing compounds: A green technique for protection of alcohols using Si-O bond formations

The development of catalytic silylation of alcohols under ambient reaction conditions plays an important role in organic synthesis. New silyl groups and methods for their introduction and removal are constantly being developed and offer chemists a wider range of options. In recent years, silyl protecting groups have been given expanded roles beyond their traditional use of temporarily rendering inactive alcohols. As silyl ether can be further converted to the parent alcohols in acidic conditions, silylation of alcohols can be regarded as an alternative method for hydroxyl protection under ambient reaction conditions. Merging the silyl protection/deprotection of alcohols with such modern methodologies, as green chemistry and nanoscience, has added additional value to these temporary components of synthetic intermediates. This review describes the historical background of the trimethylsilyl ethers preparation from alcohols using catalytic complexes and also the transformation of trimethylsilyl ethers into alcohol-containing compounds via deprecation techniques.

High conductivity and alkali-resistant stability of imidazole side chain crosslinked anion exchange membrane

Poly (aryl ether ketone) polymers (PAEKS) were synthesized by polycondensation of trimethyl hydroquinone, allyl bisphenol S and 4,4-difluorodiphenyl ketone as monomers. A series of uncrosslinked and crosslinked anion exchange membranes (AEMs) with diverse contents of 1-allyl-3-methylimidazolium chloride and 1-vinylimidazole were prepared by grafting and bromination reaction. The 1-vinylimidazole in the AEMs was simultaneously present as a crosslinked agent. (HNMR)-H-1 and FT-IR spectra demonstrated the structure of the above PAEKS and AEMs, respectively. TEM images and SAXS profiles showed the formation of distinct hydrophilic/hydrophobic microphase separation in the TCImP membranes, which offered vast of channels for ion transmission. Among them, TCImP-3 membrane showed the highest hydroxide conductivity of 0.144 S/cm at 80 degrees C. Compared with the uncrosslinked AEMs, the crosslinked AEMs exhibited slightly lower water uptake and swelling ratio. The crosslinked structures in the AEMs were helpful to improve the mechanical property and alkali-resistant stability of AEMs. The hydroxide conductivity of the TCImP-3 membrane kept 0.117 S/cm in 2 M NaOH solutions at 80 degrees C for 400 h. Meanwhile, crosslinked AEMs showed excellent thermostability. We believe that TCImP membranes are a promising AEMs material.

Does the salt really matter? Impact of the counterion upon ECL signal

The incorporation of counterions into a variety of substances to control a number of their physiochemical properties is vital within a range of fields. Electrochemiluminescence (ECL) based sensors have grown in popularity in recent years with their employment observed across analytical and bioanalytical applications. ECL is typically concerned with the core electroactive functionality of the species of interest, with structural similarities commonly employed to determine the likelihood of a species ECL capability. However, to date no consideration has been given to the impact of different counterions toward an analytes ECL mechanism. Here we report for the first time how a simple alternation to a co-reactants counterion can significantly impact upon its recorded ECL response. Utilizing the tropane alkaloid scopolamine and its hydrobromide and hydrochloride salt forms, we have seen through interrogation with the traditional ruthenium luminophore, that replacement of the bromide anion for the chloride anion can reduce the electroactivity of the species. Direct comparison between the hydrobromide and hydrochloride salt forms relived differences in respect of their emission potentials and intensities. The impact of the salt form upon the ECL response has here been investigated, in respect to predicted concentrations. Results demonstrated how vastly different concentrations were obtained dependent upon the salt form present within the sample and that which was used to produce the calibration curve. The impact of this discovery will be of interest to the electrochemiluminescent and electroanalytical communities, and in particular forensic practitioners where electrochemical and ECL based sensors are of increasing interest. Ultimately the application of an ECL sensor within an analytical environment relies upon its accuracy and hence a thorough understanding of the phenomenon observed will only stand to widen the acceptance of ECL within the wider analytical community and increase its potential future applications.

Evaluation of Anti-depressant and Anti-anxiety Activity of Methanol Extract of Stachys annua L. in Mice

Background and objectives: Development of new medicines with fewer side effects and more efficacy is needed for treatment of depressive and anxiety disorders. The present study was designed to investigate the antidepressant and anti-anxiety effects of Stachys annua L. methanol extract in mice. Methods: The extract was prepared by maceration method and the total phenolic and flavonoid contents were determined by Folin-Ciocalteu and aluminum chloride methods, respectively. Elevated plus-maze (EPM) and open field tests (OFT) were applied to evaluate the anti-anxiety and locomotor activity of animals treated with the intraperitoneal (i.p.) extract (12.5, 25, 50, and100 mg/kg), respectively. Antidepressant activity was evaluated by forced swim test (FST) and tail suspension test (TST). Results: The total phenolic content of the extract was 54.13 +/- 0.01 mg of gallic acid equivalents per gram of dry extract and total flavonoid content was 67.89 +/- 0.005 mg of quercetin as equivalents/ g of extract. Intraperitoneal administration of the extract (50 and 100 mg/kg) significantly increased the percentage of time spent and the percentage of arm entries into the open arms of EPM and decreased locomotor activity, compared with the vehicle control group. In addition, the immobility time of animals significantly decreased in both FST and TST with doses of 25, 50, and 100 mg/kg of the extract, compared with the vehicle control group. Conclusion: The extract of Stachys annua L. might be used as an adjunct therapy in clinical studies for the treatment of depressive and anxiety disorders. However, determination of active ingredients needs further evaluation.

Selective extraction of quinolizidine alkaloids from Sophora flavescens Aiton root using tailor-made deep eutectic solvents and magnetic molecularly imprinted polymers

In this study, an eco-friendly extraction method that used tailor-made deep eutectic solvents (DESs) for the extraction of oxymatrine and matrine from Sophora flavescens Aiton root was implemented for the first time. The extraction parameters, including the DES type, DES water content, solid-to-liquid ratio, extraction time, and extraction temperature, which affected the extraction efficiencies of oxymatrine and matrine were optimised. High-performance liquid chromatography with a diode-array detector and quantitative analysis of the DES components was conducted. The highest oxymatrine and matrine extraction yields (21.04 and 1.53 mg.g(-1), respectively) were obtained using DES-2 (comprising choline chloride and malonic acid; molar ratio of 1:2) with 50% water and DES-8 (comprising choline chloride and ethylene glycol; molar ratio of 1:2) with 30% water as the extraction solvents, respectively. Furthermore, magnetic molecularly imprinted polymers (MMIPs) were successfully synthesised using oxymatrine, acrylic acid, ethylene glycol dimethylacrylate, azobisisobutyronitrile, and acetonitrile-methylbenzene (3:1, v/v) as the template, functional monomer, cross-linker, initiator, and porogen, respectively. The MMIPs were characterised using transmission electron microscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction analyses, and the results demonstrated the successful preparation of MMIPs. The adsorption properties of MMIPs were further analysed using static and dynamic adsorption experiments, and the results indicated that MMIPs presented good adsorption capacities for oxymatrine and matrine (110.8 and 63.4 mg.g(-1), respectively). Lastly, MMIPs were used as sorbents for the extraction and enrichment of oxymatrine and matrine from DES extracts of S. flavescens roots. The extraction efficiencies of oxymatrine and matrine (80.21-89.15% and 85.33-95.28%, respectively) were satisfactory. The proposed DES-based extraction followed by MMIPs secondary enrichment appeared to be an effective method for the selective extraction of specific components from complex samples.

Enhanced removal of aqueous phenol with polyimide ultrafiltration membranes embedded with deep eutectic solvent-coated nanosilica

Novel composite hydrophilic ultrafiltration (UF) membranes, comprising a polyimide (PI) matrix embedded with silica-based nanofillers are established for the enhanced vacuum-filtration removal of small polar organics such as phenol from water. Spherical silica nanoparticles are first prepared by the surfactant-templated sol-gel approach, then coated with choline chloride-ethylene glycol deep eutectic solvent (DES) by post-impregnation. The modified silica nanofillers are introduced into the PI matrix through the casting solution, which is then used to develop the composite UF membranes by phase inversion. The spectroscopy and high-resolution electron microscopy measurements evidence the presence of DES on the surface of the modified silica nanofillers. The topographical atomic force microscopy studies, dynamic water contact angle, and zeta potential measurements conducted on the native polymer membrane and those embedded with bare-silica and DES-coated silica confirm the successful incorporation of nanofillers into the PI matrix. An optimum nanofiller loading of 2 wt% is found to preserve the membrane structure and give the best mechanical properties as well as for the UF performance characteristics in vacuum-filtration studies at 85 kPa. Consistently, the DES-silica modified PI UF membranes (DES@SiO2@PI) exhibit exceptional water permeate flux (300 L m(2) h(-1)) and removal efficiency (96%) for 30 mg L-1 aqueous phenol compared with the native polymer and SiO2-modified membranes. The DES-engineered composite membranes can be operated within a wide feed pH window (pH: 2-10) without displaying significant loss in their removal efficiency. The pH and zeta potential results suggest that the interaction of phenol with the optimized membranes is governed by cooperative adsorption/Lewis acid-base mechanisms via hydrogen bonding and assistive ion-exchange interactions with the ethaline coating.

Determination of 2-acetyl-1-pyrroline in alginate encapsulated pandanus flavorings by static headspace (SHS) and gas chromatography with nitrogen-phosphorus detection (GC-NPD)

A new form of Pandanus flavoring has been developed using the ionic gelation method. Among the four Pandanus species investigated by solid-phase microextraction (SPME)-gas chromatography-mass spectrometry (GC-MS), the leaves of P. amaryllifolius Roxb. contained the highest content of the impact aroma compound, 2-acetyl-1-pyrroline. Some terpene volatiles were identified for the first time in these Pandanus species. Acidic extraction with aqueous tartaric acid at pH 5 was the most suitable solvent for obtaining 2-acetyl-1-pyrroline from Pandanus leaves. Moreover, the extract was directly subjected to ionic gelation with the optimized sodium alginate and calcium chloride concentrations of 1.5 and 3% w/v, respectively. Automated static headspace-gas chromatography with a selective nitrogen-phosphorus detection was developed and validated to determine 2-acetyl-1-pyrroline in the dried green alginate beads. The response surface optimization of headspace sample parameters resulted in an optimal equilibration time of 20 min and oven temperature at 123 degrees C. The 2-acetyl-1-pyrroline standard calibration curve was linear from 1.0 to 640 mu g g(-1) with a correlation coefficient of 0.9998. The limits of detection and quantification were 0.10 and 0.80 mu g g(-1), respectively. On average, a 2-acetyl-1-pyrroline content of 18.49 mu g g(-1) (16.89 to 26.91 mu g g(-1)) was encapsulated in the green dried alginate flavoring products, which was two to three times higher than contained in fresh Pandanus leaves. After 90 days of storage, the 2-acetyl-1-pyrroline content remaining in the green dried alginate beads was 79% of the initial content.

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.
