Published: June 2023

AbstractVoltage-gated potassium (Kv) channels in the KCNQ subfamily serve essential roles in the nervous system, heart, muscle and epithelia. Different heteromeric KCNQ complexes likely serve distinct functions in the brain but heteromer subtype-specific small molecules for research or therapy are lacking. Rosemary (Salvia rosmarinus) is an evergreen plant used medicinally for millennia for neurological and other disorders. Here, we report that rosemary extract is a highly efficacious opener of heteromeric KCNQ3/5 channels, with weak effects on KCNQ2/3. Using functional screening we find that carnosic acid, a phenolic diterpene from rosemary, is a potent, highly efficacious, PIP2 depletion-resistant KCNQ3 opener with lesser effects on KCNQ5 and none on KCNQ1 or KCNQ2. Carnosic acid is also highly selective for KCNQ3/5 over KCNQ2/3 heteromers. Medicinal chemistry, in silico docking, and mutagenesis reveal that carboxylate-guanidinium ionic bonding with an S4-5 linker arginine underlies the KCNQ3 opening proficiency of carnosic acid, the effects of which on KCNQ3/5 suggest unique therapeutic potential and a molecular basis for ancient neurotherapeutic use of rosemary.

Published: June 2023

AbstractFragment-based drug discovery is an established methodology for finding hit molecules that can be elaborated into lead compounds. However it is currently challenging to predict whether fragment hits that do not bind to an orthosteric site could be elaborated into allosteric modulators, as in these cases binding does not necessarily translate into a functional effect. We propose a workflow using Markov State Models (MSMs) with steered molecular dynamics (sMD) to assess the allosteric potential of known binders. sMD simulations are employed to sample protein conformational space inaccessible to routine equilibrium MD timescales. Protein conformations sampled by sMD provide starting points for seeded MD simulations, which are combined into MSMs. The methodology is demonstrated on a dataset of protein tyrosine phosphatase 1B ligands. Experimentally confirmed allosteric inhibitors are correctly classified as inhibitors, whereas the deconstructed analogues show reduced inhibitory activity. Analysis of the MSMs provide insights into preferred protein-ligand arrangements that correlate with functional outcomes. The present methodology may find applications for progressing fragments towards lead molecules in FBDD campaigns.

AbstractPlastic pollution in the world’s rivers and ocean is increasingly threatening ecosystem health and human livelihood. In contrast to what is commonly assumed, most mismanaged plastic waste that enters the environment is not exported into the ocean. Rivers are therefore not only conduits but also reservoirs of plastic pollution. Plastic mobilization, transport and retention dynamics are influenced by hydrological processes and river catchment features (for example, land use, vegetation and river morphology). Increased river discharge has been associated with elevated plastic transport rates, although the exact relation between the two can vary over time and space. However, the precise role of an extreme discharge event on plastic transport is still unknown. Here we show that fluvial floods drive macroplastic (>2.5 cm) transport (items h−1) and accumulation (items m−2) in river systems. We collected unique observational evidence during the July 2021 flood along the whole Dutch part of the Meuse. Plastic transport multiplied by a factor of over 100 compared with non-flood conditions (3.3 × 104versus 2.3 × 102items h−1). Over one-third of the modelled annual plastic item transport was estimated to occur within 6 days of extreme discharge. Between Maastricht and Ravenstein (291 km and 131 km from the river mouth), plastic transport during the flood period decreased by 90%, suggesting that the dispersal of plastic mobilized during the flood is limited due to the entrapment on riverbanks, in vegetation and on the floodplains. Plastic transport and accumulation on the riverbanks decreased significantly along the river, corroborating the river’s function as a plastic reservoir. Using new observational evidence, we demonstrate the crucial role of floods as drivers of plastic transport and accumulation in river systems. Floods amplify the mobilization of plastics, but the effects are local, and the river-scale dispersal is limited. We anticipate that our findings will serve as a starting point for improving global estimates of river plastic transport, retention and export into the sea. Moreover, our results provide essential insights for future large-scale and long-term quantitative assessments of river plastic pollution. Reliable observations and a fundamental understanding of plastic transport are key to designing effective prevention and reduction strategies.

Abstract
Background Aortic valve replacement with mechanical valves is the standard treatment for aortic valve disease in Indonesia. Its usage is associated with high cost, risk of endocarditis and thromboembolic event, and lifetime consumption of anticoagulants. We performed a novel replacement technique of the aortic valve using an autologous pericardium and evaluated the short-term outcomes.
Methods From April 2017 to April 2020, 16 patients underwent aortic valve replacement with a single-strip autologous pericardium. Outcomes of the left ventricular reverse remodeling (LVRR), 6-minute walk test (6MWT), and soluble suppression of tumorigenicity-2 (sST-2) were measured at 6 months postoperation.
Results A total of 16 surgeries were performed using aortic valve replacement with single-strip pericardium without conversion to mechanical valve replacement. The patients included eight males and eight females, and the mean age was 49.63 ± 12.54 years. The most common diagnosis was mixed aortic valve stenosis and regurgitation (9 cases). Five patients underwent a concomitant coronary artery bypass graft (CABG) procedure and 12 patients underwent either mitral or tricuspid valve repair. The mean aortic cross-clamp time was 139.88 ± 23.21 minutes and cardiopulmonary bypass time was 174.37 ± 33.53 minutes. At 6 months postoperation, there was an increase in the distance walked at the 6MWT (p = 0.006) and a decrease of the sST-2 level (p = 0.098). Echocardiogram showed two patients had LVRR. Survival and freedom from reoperation are 100% at 1 year of follow-up.
Conclusion Aortic valve replacement with a single strip of pericardium is a good alternative to aortic valve replacement with a mechanical valve. Short-term evaluation at 6 months postoperation showed improvement in clinical status and echocardiographic parameters compared to baseline.
Paratexts as a site of cultural reflection
Authors: Moratto Riccardo , Xu Qianqian 
Published: June 2023

Abstract
In the Ming and Qing dynasties the translation of Western books fueled the phenomenon known as Eastward
Transmission of Western Sciences. In this context, the collaborative translation of The Chinese Classics by James
Legge (1815–1897) and Wang Tao (1828–1897) was of particular significance because it promoted the transmission of Eastern learning
to the West in the late Qing dynasty. This process of collaborative translation provided an opportunity for cultural interaction
between China and the West; at the same time, it also generated competition between the two cultures. This paper sets out to
investigate the paratexts written by the two co-translators, namely Legge and Wang, and aims to answer the following questions:
How did the translation process of The Chinese Classics generate a dialectical interaction and why did it create
a cultural struggle between the two translators? What impact did such a cultural collision exert on the translation and
interpretation of The Chinese Classics and its reception in the West?
Influence of binder and solvents on the electrochemical performance of screen-printed MXene electrodes
Authors: Chavan Rutuja A , Ghule Anil Vithal 
Published: June 2023

Abstract
The present study is concerned with the use of binders and solvents in fabricating MXene electrodes, which play a vital role in influencing supercapacitive performance. The electrodes were prepared by screen printing MXene on flexible stainless steel mesh (FSSM) substrate, which is a straightforward, efficient, and cost-effective approach. The influence of binder and solvent on the electrochemical performance was investigated by fabricating them with and without using a binder i.e. only organic solvents ethanol and n-methyl-2-pyrrolidone (NMP). The electrode with the binder is abbreviated as MX-B@FSSM and was prepared with the composition of acetylene black conducting material, polyvinylidene fluoride (PVDF) polymer binder, and MXene (MX) as active material. While electrodes without binder were prepared by a slurry of MXene using organic solvent ethanol and NMP and are abbreviated as MX-E@FSSM and MX-N@FSSM, respectively. The electrochemical performance of these MX-B@FSSM, MX-E@FSSM and MX-N@FSSM electrodes was examined by cyclic voltammetry, chronopotentiometry, and electrochemical impedance spectroscopy. The influence of the binder altered the electrochemical performance. The samples MX-B@FSSM, MX-E@FSSM, and MX-N@FSSM show the specific capacitance of 35.60, 490.80, and 339.6 F g−1, respectively at 2 mA cm−2 current density. The MX-E@FSSM electrode exhibited marginally the best electrochemical performance. Furthermore, MnO2/MXene//MX-E asymmetric supercapacitor device exhibits 252 F g−1 specific capacitance at 35.2 Wh kg−1 energy density demonstrating a promising electrode for the supercapacitor.
Physical mechanism of electrode coatings to suppress wire particle’s firefly motion under DC stress and selecting criterion for in situ applications

Published: June 2023

Abstract
The Wire metal particles in gas-insulated equipment such as GIS (Gas-Insulated Substation) and GIL (Gas-Insulated transmission lines) under DC stress present a special firefly motion behaviour, namely a long-term levitation on the surface of conductors. However, the electrode coating, as a key device available to suppress the movement of particles, lacks of a theoretical basis as well as an effective selecting criterion to suppress wire particle’s firefly. In this paper, a test platform is established to obtain the charge dynamics and ionic wind characteristics of the wire particles on the coated electrodes. Experimental results illustrate that, the polarity alternation of wire particle charge due to the space charge accumulation near the wire particles as well as the ionic wind generated by the wire particles, is the key impact factor upon firefly motion. The coated electrodes will reduce the surface conduction current and thereby suppress the particle corona discharge, consequently suppressing the firefly motion by limiting the charge acquisition and ionic wind speed of the wire particles. Based on the above research, a selecting criterion of electrode coating material is further proposed. Electrode coatings is primarily expected to increase the corona onset voltage of the wire particles on the coating surface, so as to lower the ionic wind at the end of the particles less than 1 m s−1. Regarding the high voltage conductor, the coating material with relatively large conductivity is recommended, while for the grounded enclosure, the coating material with smaller conductivity is preferable as to constrain the particles adhere to the enclosure, thereby preventing the firefly motion of wire particle. Both the clarified physical mechanism and the proposed selecting criterion of electrode coating presents theoretical and quantitative guidance for DC GIL design from a specific point of view in suppressing the firefly motion.
Uphill inflation
Authors: Briaud Vadim , Vennin Vincent 
Published: June 2023

Abstract
Primordial black holes (PBH) may form from large cosmological perturbations, produced during inflation when the inflaton's velocity is sufficiently slowed down. This usually requires very flat regions in the inflationary potential. In this paper we investigate another possibility, namely that the inflaton climbs up its potential. When it turns back, its velocity crosses zero, which triggers a short phase of “uphill inflation” during which cosmological perturbations grow at a very fast rate. This naturally occurs in double-well potentials if the width of the well is close to the Planck scale. We include the effect of quantum diffusion in this scenario, which plays a crucial role, by means of the stochastic-δN formalism. We find that ultra-light black holes are produced with very high abundances, which do not depend on the energy scale at which uphill inflation occurs, and which suffer from substantially less fine tuning than in alternative PBH-production models. They are such that PBHs later drive a phase of PBH domination.

Abstract

Objective. Monoamine dysfunction has been implicated as a pathophysiological basis of several mental disorders, including anxiety and depression. Transcranial ultrasound stimulation (TUS) is a noninvasive nerve stimulation technic showing great potential in treating depression/anxiety disorders. This study aims to investigate whether TUS can ameliorate depression with anxiety in mice by regulating brain monoamine levels. Approach. Mice received repeated subcutaneous injections of corticosterone (CORT, 20 mg kg−1) for 3 weeks to produce depression- and anxiety-like behaviors. Ultrasound stimulated the dorsal lateral nucleus (DRN) for 30 min daily for 3 weeks without interruption of CORT injection. Behavioral phenotypes of depression and anxiety were estimated by sucrose preference test (SPT), tail suspension test (TST), and elevated plus-maze test (EPM). Liquid chromatography–mass spectrometry (LC–MS) was used to quantify brain levels of serotonin (5-HT), norepinephrine (NE), and dopamine (DA). Western blotting was performed to detect brain-derived neurotrophic factor (BDNF) levels in hippocampal. Main results. TUS of DRN significantly ameliorated the depression-like behaviors in SPT (p = 0.0004) and TST (p = 0.0003) as well as anxiety-like behaviors in EPM (open arm entry frequencies, p < 0.05). Moreover, TUS increased c-Fos-positive cell expression (p = 0.0127) and induced no tissue damage. LC–MS results showed TUS of DRN resulted in a non-significant increase in the 5-HT levels and a significant decrease in the NE levels, but did not affect the levels of DA and BDNF. Significance. These results suggest TUS of DRN has safely and effectively ameliorated CORT-induced depression- and anxiety-like behaviors, possibly by restoring brain levels of 5-HT and NE. TUS may be a safe and effective technique for remedying depression and anxiety comorbidity.

Authors: Panda S. , Das M.K. , Mohapatra N. 
Published: June 2023

Abstract
Here, we report the magnetic properties of LaMnO3, LaFeO3 thin films and their heterostructures, fabricated using Pulse laser deposition technique (PLD) on SrTiO3(001) substrate. The crystal structure, surface morphology signifies the phase pure epitaxial growth of LaMnO3 and LaFeO3 films and their heterostructure. The magnetic characteristics of individual LaMnO3 and LaFeO3 films along with their heterostructures were studied to explore the proximity effect of the different antiferromagnets. We demonstrate that LaMnO3 thin film shows ferromagnetic signal with inconspicuous Tc. The ferromagnetic signal is stronger in case of LaMnO3 grown on buffered LaFeO3 and LaFeO3 on top of LaMnO3. The change of Tc is analyzed in heterostructures as compared to the bare LaMnO3. Additionally, our study illustrates the variation of anisotropic energy and spin flop coupling between the interface with alternate growth sequence of heterojunctions.

Published: June 2023

Abstract
With increasing industrialization in the modern era, the detection of hazardous gases like NH3 became a global issue due to its detrimental effect on mankind. MXene has emerged as an outstanding gas sensing candidate among two-dimensional materials due to its favorable characteristics like an abundance of interaction sites, metallic conductivity, tunable surface properties, band gap, and excellent mechanical strength. In the present work, a highly sensitive and selective NH3 gas sensor has been fabricated using MXene-based nanostructures. The morphological and structural characterizations of nanostructures have been performed using X-ray diffraction, field-emission scanning electron microscopy, and transmission electron microscopy. The successful etching of Al reveals the formation of MXene having exfoliated multilayered morphology with an average interlayer spacing of ~53 nm. The response kinetics of the sensor has been investigated by estimating their response and selectivity toward different oxidizing and reducing gases. The sensor exhibits high response transient curves toward 5–100 ppm of NH3 at room temperature (30 °C) with fast response and recovery time. Density functional theory has been used to elucidate the interaction mechanism between NH3 molecules and MXene surface.

AbstractIn this work, we show evidence of enhanced photocatalytic activity in mechanically activated graphite-zinc oxide (ZnO) composites using time-resolved photoluminescence (TRPL) and time-integrated photoluminescence (TIPL) spectroscopy. The graphite-ZnO composites were synthesized through facile mixing and grinding of graphite and ZnO precursors without any heat treatment. The precursors were ground at room temperature with varying graphite to ZnO mass ratios of 3:1, 2:2, and 1:3 for 0, 2, and 4 h. Raman spectroscopy and x-ray diffractometry confirm the presence of both graphite and ZnO and corroborate the graphite-to-ZnO ratio. XRD results also show a hexagonal wurtzite ZnO crystal structure. To determine the photocatalytic activity of the composites, the degradation of methylene blue (MB) under UV light was measured with a UV–vis spectrophotometer. Nearly full degradation was achieved within a half hour for all composite samples. The kinetic rates of 0.10 min−1were also estimated for mixed and unground samples and samples ground for 2 h. Time-resolved photoluminescence (TRPL) and time-integrated photoluminescence (TIPL) spectroscopy reveal longer lifetimes and more intense UV emissions, respectively, for composite samples compared to pure ZnO. We propose that the even agglomeration of zinc oxide particles on graphite due to grinding enhances the photocatalytic degradation by the zinc oxide. TRPL and TIPL spectroscopy implies the excellent binding between ZnO and graphite, which greatly contributes to the decreased charge recombination resulting in the superior photocatalytic activity observed with our samples.
Abstraction and semantic presuppositions
Authors: Assadian Bahram 
Published: June 2023

Abstract
According to the neo-Fregean abstractionism, numerical expressions of the form ‘the number of Fs’, introduced by Hume’s Principle, should be read as purportedly referential singular terms. I will explore the prospects of a version of abstractionism in which such expressions have presuppositional content, as in Strawson’s account. I will argue that the thesis that ‘the number of Fs’ semantically presupposes the existence of a number is inconsistent with the required ‘modest’ stipulative character of the truth of Hume’s Principle: since Hume’s Principle is true and provably presupposes that numbers exist, what it presupposes is also true; and so numbers exist. This, however, means that numbers are conjured into existence by a direct stipulation.

Abstract

Ophthalmic pharmaceutical preparation containing antazoline (ANT) and tetryzoline (TET) is prescribed widely as an over the counter medication for allergic conjunctivitis treatment. Development of a selective, simple and environmentally friendly thin-layer chromatographic method established to determine both ANT and TET in their pure forms, pharmaceutical formulation and spiked aqueous humor samples. By using silica gel plates and means of a developing system consists of ethyl acetate:ethanol (5:5, by volume), the studied drugs separation was achieved, and scanning was carried out at 220.0 nm for the separated bands with a 0.2–18.0 μg/band concentration range for each of ANT and TET. Standard addition technique application was carried out to determine the proposed method validity. Statistical comparison was made between the proposed method and the official methods ANT and TET showing no significant difference concerning accuracy and precision. Furthermore, greenness profile assessment was accomplished by means of four metric tools, namely, analytical greenness, green analytical procedure index, analytical eco-scale and national environmental method index.
