High diversity of microsporidian parasites and new planktonic hosts in freshwater and marine ecosystems
Authors: Chauvet Marina , Monjot Arthur , Lepère Cécile 
Published: February 2023

AbstractMicrosporidia are a large group of obligate intracellular eukaryotic parasites related to fungi primarily known as parasites of vertebrates and invertebrates. They are well described as parasites of organisms of interest (e.g., edible fish and crustaceans, honeybees, bioindicators such as daphnia, humans) on which they can have an important impact (e.g., reduced survival or fecundity and sex ratio distortion). However, their diversity in aquatic environments, especially in marine ecosystems, has been greatly understudied since they are not targeted by classical eukaryotic primers used in metabarcoding studies. Moreover, little is known about their hosts among protists or microzooplankton and therefore about their impact on the trophic food web functioning. In this work, we sampled 15 different sites across marine and freshwater environments, size‐fractioned the samples, and used microsporidian specific primers associated with metabarcoding to study the microsporidian diversity (and the associated spatial variation). Co‐occurrence networks as well as tyramide signal amplification‐fluorescent in situ hybridization were used to link potential hosts (planktonic eukaryotes < 150 μm) and Microsporidia diversity. Our analysis unraveled a large microsporidian diversity which was widely divergent between the two environments studied. In both of them, an important part of this diversity was not affiliated to a genus, suggesting an important reservoir of new microsporidian species and thus new hosts among planktonic eukaryotes. Co‐occurrence networks and fluorescence microscopy showed for the first‐time associations between Microsporidia and dinoflagellates in freshwater and marine environments.

AbstractGraphene oxide (GO) is an oxidized form of graphene, laced with oxygen‐containing groups. In recent years, the cost‐effective and efficient synthesis of GO remains a significant issue. Hummer's method has become popular due to its simple top‐down synthesis, however, there is an issue due to the release of nitrate gaseous which is harmful to the environment. This research is carried out using regenerated carbon from waste tire as a source of synthesize process through the Hummers Method (HM) and Improved Hummers Method (IHM). The Raman peaks of IHM GO show that the D band and G band are at 1369.12 and 1583 cm−1, respectively and the intensity ratio of the D band relative to the G band (ID/IG) is 0.84. The morphology and structure of graphene oxide show that a nanosize particle stalked together on the surface of the sample structure, bumping pieces, and a coarse surface. The elemental composition of carbon (C) is higher than the oxygen (O) element which showed a good composition of graphene oxide. The XRD spectroscopy indicates the crystal structure of the material and the interlayer spacing between the material and atoms. In this study, the improved method is used by replacing sodium nitrate (NaNO3) with phosphoric acid (H3PO4) during the synthesis process to help increase interlayer distance and helps oxidation on the basal planes. This result confirms that the graphene oxide can be synthesized from regenerated carbon from waste tire using an improved Hummer's method.

AbstractOne of the recent and actively researched areas is the synthesis of bimetallic nanoparticles (BMNPs). Silver and gold BMNPs are prepared from aqueous AgNO3 and HAuCL4 as the precursors using the as prepared culture filtrate of Rhodopseudomonas faecalis as a reducing agent in aqueous medium. An ambient temperature of 25°C is maintained throughout the process, where the AgNO3 and HAuCL4 solution in 1:1 v/v is stirred continuously and culture filtrate is added. The synthesis of gold and silver nanoparticles is shown by the brown color which indicates the formation of composite nanoparticles. The characterization is done using different kinds of techniques. Synthesized nanoparticles size is in the range between 31.71 and 153.7 nm. Scanning electron microscopy (SEM) analysis shows that the nanoparticles are in small and round in shape. The anticancer and antimicrobial activities of the BMNPs are investigated. Anticancer activity of composite nanoparticles reveals that the composite nanoparticles show more cytotoxicity toward cancer cell lines HT‐29 and MCF‐7. The synthesized composite nanoparticles can be used as efficient antimicrobials and anticancer agents for diagnosis, treatment of various infections, and cancers.

AbstractCharcoal prepared from Kail Sawdust (waste obtained from carpenter shop) has been used as adsorbent for the simultaneous removal of red RB (RRB) and yellow M4G (YMG) dyes from water. The interactive effect of both dyes is found as antagonistic. The experiments are performed on optimized operating parameters, which are based on individual dye adsorption. Experimental results are tested for Langmuir, Freundlich, and Temkin adsorption isotherm models but the equilibrium data fitt well with Langmuir isotherm model. Adsorption kinetics fit well pseudo second order kinetic model. FTIR, SEM, and BET analysis are used to characterize the adsorbent. Adsorption process is spontaneous, feasible, and exothermic as proved by thermodynamic parameters. From the outcomes, it is presumed that removal of dyes by KSC (bioadsorbent) can be proved as successful and green innovation for the treatment of textile industrial wastewater.

Published: February 2023

AbstractPiezoelectric MEMS (Micro‐Electro‐Mechanical Systems) Cantilevers have successfully been used in a wide variety of applications in recent years. This paper is a simulation‐based study on Micro‐cantilever based Piezoelectric MEMS biosensors for Chikungunya Virus (CHIKV) detection. In addition to providing early detection, the proposed method is label‐free, faster, and more reliable. The proposed biosensor detects CHIKV E2 protein via MEMS Sensor. The basic principle involves using piezoelectric material on a micro‐cantilever for biomaterial detection. A piezoelectric MEMS cantilever is simulated in COMSOL Multiphysics and compared for voltage, stress, and displacement for three materials (silicon, gold, and PDMS). Analytical equations are derived. Post‐processing for biosensor design is done in SIMULINK. Simulated voltage, stress, and displacement show a linear relationship with the viral load. PDMS also provided the highest voltage and displacement among the three materials used for MEMS simulation. The graphs show the comparison between simulated and analytical values. Simulation results are also compared to clinical results to prove the biosensor's validity. MEMS Biosensor performance matches with the RT‐PCR results, with the added advantage of faster results. Diagnostic tests in the medical field can be performed using the proposed biosensor.

AbstractElectrical energy plays an important role in the day‐to‐day life and backbone for the industries. Today life without electricity cannot be imagined. Because of the unnecessary actions taken by human beings, wastage and theft of power are increasing day by day. Theft of electricity is the criminal practice of stealing electrical power. It is a crime and is punishable by fines and/or incarceration. It belongs to the non‐technical losses. The objective of this work is to design a system that will try to minimize the illegal use of electricity and also reduce the chances of theft, and if theft happens appropriate actions will be taken. To identify and control power theft here, an intelligent system is introduced. It consists of two current transformers that are used to measure the actual load current and the other is to measure the turning back or neutral current. Those two current signals are fed to the micro controller. The micro controller will compare these two current signals. Depending on the comparison made by the micro controller it concludes whether power is theft through bypassing the energy.

The governance of rent‐seeking behavior in carbon asset pledge financing: An evolutionary game perspective
Authors: Fu Shuaishuai , Chen Weida , Ding Junfei 
Published: February 2023

AbstractAs an emerging financing model in the carbon financial market, carbon asset pledge financing (CAPF) has received extensive attention from governments and firms with the advance of low‐carbon economy. Since enterprises, banks, third‐party carbon asset evaluation agencies (TCAs), governments, etc, are involved in the operation of CAPF, driven by information asymmetry and the interaction among different stakeholders, rent‐seeking behavior is easy to occur in CAPF. This paper develops an evolutionary game model to investigate the rent‐seeking behavior in CAPF among different stakeholders. In addition, the risk‐sharing and penalty mechanisms are also taken into account. Subsequently, we examine the effect of relevant parameters on the dynamic evolution strategy of all parties in CAPF rent‐seeking through numerical examples. The results show that the governance of rent‐seeking behavior in CAPF needs the cooperation of different participating entities, the improvement of carbon financial market can reduce the occurrence of rent‐seeking behavior in CAPF. Compared with firms, TCAs are more susceptible to opportunism. Additionally, both the risk‐sharing mechanism and the penalty mechanism can effectively reduce the occurrence of rent‐seeking behavior. This paper contributes to the management of CAPF, and managerial insights for the governance of rent‐seeking behavior in CAPF are also provided.

AbstractObjectiveImproving mitochondrial function is a promising strategy for intervention in type 2 diabetes mellitus. This study investigated the preventive effects of sodium ferrous citrate (SFC) and 5‐aminolevulinic acid phosphate (ALA) on several metabolic dysfunctions associated with obesity because they have been shown to alleviate abnormal glucose metabolism in humans.MethodsSix‐week‐old male C57BL/6J mice were fed with a normal diet, a high‐fat diet, or a high‐fat diet supplemented with SFC and ALA for 15 weeks.ResultsThe simultaneous supplementation of SFC + ALA to high‐fat diet‐fed mice prevented loss of muscle mass, improved muscle strength, and reduced obesity and insulin resistance. SFC + ALA prevented abnormalities in mitochondrial morphology and reverted the diet effect on the skeletal muscle transcriptome, including the expression of glucose uptake and mitochondrial oxidative phosphorylation‐related genes. In addition, SFC + ALA prevented the decline in mitochondrial DNA copy number by enhancing mitochondrial DNA maintenance and antioxidant transcription activity, both of which are impaired in high‐fat diet‐fed mice during long‐term fasting.ConclusionsThese findings suggest that SFC + ALA supplementation exerts its preventive effects in type 2 diabetes mellitus via improved skeletal muscle and mitochondrial health, further validating its application as a promising strategy for the prevention of obesity‐induced metabolic disorders.

AbstractHepatic angiosarcoma (HAS) is an aggressive mesenchymal malignancy that remains underexplored with respect to its etiology and mutational landscapes. To clarify the association between HAS and end‐stage renal disease (ESRD), we used nationwide data of the National Health Insurance Research Database (NHIRD) in Taiwan, covering ~99% of the population, from 2001 to 2016. To investigate molecular signatures, we performed whole‐exome sequencing (WES) in 27 surgical specimens, including nine ESRD‐associated cases. The NHIRD analysis demonstrated that HAS ranked second among all angiosarcomas in Taiwan, with the incidence rates of HAS being 0.08, 2.49, and 5.71 per 100,000 person‐years in the general population, chronic kidney disease (CKD), and ESRD patients, respectively. The standardized incidence ratios of HAS in CKD and ESRD patients were 29.99 and 68.77, respectively. In comparison with nonhepatic angiosarcoma, the multivariate regression analysis of our institutional cohort confirmed CKD/ESRD as an independent risk factor for HAS (odds ratio: 9.521, 95% confidence interval: 2.995–30.261, p < 0.001). WES identified a high tumor mutation burden (TMB; median: 8.66 variants per megabase) and dominant A:T‐to‐T:A transversion in HAS with frequent TP53 (81%) and ATRX (41%) mutations, KDR amplifications/gains (56%), and CDKN2A/B deletions (48%). Notably, ESRD‐associated HAS had a significantly higher TMB (17.62 variants per megabase, p = 0.01) and enriched mutational signatures of aristolochic acid exposure (COSMIC SBS22, p < 0.001). In summary, a significant proportion of HAS in Taiwan is associated with ESRD and harbors a distinctive mutational signature, which concomitantly links nephrotoxicity and mutagenesis resulting from exposure to aristolochic acid or related compounds. A high TMB may support the eligibility for immunotherapy in treating ESRD‐associated HAS. © 2023 The Pathological Society of Great Britain and Ireland.

AbstractAntimicrobial susceptibility testing (AST) is a critical function of the clinical microbiology laboratory and is essential for optimizing care of patients with infectious diseases, monitoring antimicrobial resistance (AMR) trends, and informing public health initiatives. Several methods are available for performing AST including broth microdilution, agar dilution, and disk diffusion. Technological advances such as the development of commercial automated susceptibility testing platforms and the advent of rapid diagnostic tests have improved the rapidity, robustness, and clinical application of AST. Numerous accrediting and regulatory agencies are involved in the process of AST and setting and revising breakpoints, including the U.S. Food and Drug Administration and the Clinical and Laboratory Standards Institute. Challenges to optimizing AST include the emergence of new resistance mechanisms, the development of new antimicrobial agents, and generation of new data requiring updates and revisions to established methods and breakpoints. Together, the challenges in AST methods and their interpretation create important opportunities for well‐informed clinicians to improve patient outcomes and provide value to antimicrobial stewardship programs, especially in the setting of rapidly changing and increasing AMR. Addressing AST challenges will involve continued development of new technologies along with collaboration between clinicians and the laboratory to facilitate optimal antimicrobial use, combat the increasing burden of AMR, and inform the development of novel antimicrobials. This updated primer serves to reinforce important principles of AST, and to provide guidance on their implementation and optimization.

AbstractHerein, high‐efficiency microwave shielding networks are constructed in multi‐walled carbon nanotube/poly(ε‐caprolactone) (CNT/PCL) composites by adding carbon black (CB) or graphene nano‐plates (GNPs). The synergistic effect of carbonaceous fillers with different rdimensions is investigated to obtain the optimal electromagnetic shielding performance of the composites. The CNT/GNP/PCL, CNT/CB/PCL and CB/GNP/PCL composites with different ratios were prepared by melt mixing and hot press molding for the microwave shielding evaluation. Because of the synergistic effect, the microwave shielding effectiveness values of 53.8 and 54.6 dB, which are achieved in the CNT9/CB1/PCL (CNT:CB = 9:1) and CNT9/GNP1/PCL (CNT:GNP = 9:1) composites, respectively, are higher than the value of 46.4 dB for the CNT/PCL composites with the same filler content of 4.12 vol%. The synergistic effect between carbonaceous fillers is attributed to the high‐efficiency shielding networks which can be easily formed by carbonaceous fillers with different dimensions. © 2023 Society of Industrial Chemistry.
