2Magnesium degradation under physiological conditions - Best practice显示文摘This review focusses on the application of physiological conditions for the mechanistic understanding of magnesium degradation.Despite the undisputed relevance of simplified laboratory setups for alloy screening purposes,realistic and predictive in vitro setups are needed.Due to the complexity of these systems,the review gives an overview about technical measures,defines some caveats and can be used as a guideline for the establishment of harmonized laboratory approaches.Jorge Gonzalez Rui Qing Hou Eshwara P.S.Nidadavolu Regine Willumeit-Romer Frank Feyerabend 2018Bioactive Materials2018,3,2:8
3In vitro antibacterial effect of aqueous and ethanolic Moringa leaf extracts显示文摘Objective:To evaluate the antibacterial effect of aqueous and ethanolic moringa leaf extracts (Moringa oleifera) on the growth of gram-positive and negative bacteria.Methods:Paper disks were soaked with 100,200,300 and 400μL of extract at 20 g/180mL and 10 g/190 mL.All extracts were tested against Escherichia coli(ATCC25922),Staphylococcus aureus(ATCC25923),Vibrio parahaemolyticus,Enterococcus faecalis(ATCC29212),Pseudomonas aeruginosa(ATCC27853), Salmonella enteritidis(IH) and Aeromonas caviae.The susceptibility tests were performed using the modified disk diffusion method.Results:The strains E.coli,P.aeruginosa and S.enteritidis (IH) were resistant to all treatments.In general,disks with 400μL extract were the most efficient against S.aureus,V.parahaemolyticus,E.faecalis and A.caviae.Conclusions:The study indicates a promising potential for aqueous and ethanolic Moringa leaf extracts as alternative treatment of infections caused by the tested strains.Jackson Rafael Oliveira Peixoto Giselle Cristina Silva Renata Albuquerque Costa Joseires Lira de Sousa Fontenelle Gustavo Hitzschky Fernandes Vieira Antonio Adauto Fonteles Filho Regine Helena Silva dos Fernandes Vieira 2011Asian Pacific Journal of Tropical Medicine2011,4,3:7
4Alloying effect of silver in magnesium on the development of microstructure and mechanical properties by indirect extrusion显示文摘The effect of Ag in solid solution on the microstructure,texture and the deformation behaviour of indirectly extruded Mg was investigated.Ag as a solid solution strengthener affects the behaviour during extrusion,resulting in enhanced deformation related heating and corresponding coarser grained microstructures.No substantial effect on the texture development is revealed.The mechanical properties simultaneously increase in stress and strain levels with increasing Ag content,especially in tension as a result of the changing impact of the slip modes which can be associated with a decrease of the lattice parameters as well as the c/a ratio of the hcp lattice structure.In compression tests with twin dominated flow,the impact is much smaller on the compressive yield stress but higher with respect to the twinning related strain hardening rate.Solid solution strength functions for Fleischer and Labusch were determined,also confirming the anisotropic behaviour of the extruded Mg alloys.Bjorn Wiese Regine Willumeit-Römer Dietmar Letzig Jan Bohlen 2021Journal of Magnesium and Alloys2021,9,1:3

6Deteriorated corrosion performance of micro-alloyed Mg-Zn alloy after heat treatment and mechanical processing显示文摘The corrosion performances of the as-cast and solution-treated Mg-0.5Zn samples were investigated in 0.9%Na Cl solution and compared.From the electrochemical measurement results and corrosion morphology observations,it is found that the corrosion resistance of Mg-0.5Zn deteriorated with the extension of solution treatment duration.The main reason was the formation of Fe-Si precipitates with higher Fe concentrations during heat treatment.The Fe-Si precipitates,especially the ones with high Fe contents influenced the corrosion initiation and propagation significantly.In regard of corrosion performance,the solution-treated and then extruded sample was also performing not as good as the cast and then directly extruded sample.Yiming Jin Carsten Blawert Hong Yang Bjorn Wiese Jan Bohlen Di Mei Min Deng Frank Feyerabend Regine Willumeit 2021Journal of Materials Science & Technology2021,,33:3

8An electronic nose using a single graphene FET and machine learning for water, methanol, and ethanol显示文摘The poor gas selectivity problem has been a long-standing issue for miniaturized chemical-resistor gas sensors.The electronic nose(e-nose)was proposed in the 1980s to tackle the selectivity issue,but it required top-down chemical functionalization processes to deposit multiple functional materials.Here,we report a novel gas-sensing scheme using a single graphene field-effect transistor(GFET)and machine learning to realize gas selectivity under particular conditions by combining the unique properties of the GFET and e-nose concept.Instead of using multiple functional materials,the gas-sensing conductivity profiles of a GFET are recorded and decoupled into four distinctive physical properties and projected onto a feature space as 4D output vectors and classified to differentiated target gases by using machine-learning analyses.Our single-GFET approach coupled with trained pattern recognition algorithms was able to classify water,methanol,and ethanol vapors with high accuracy quantitatively when they were tested individually.Furthermore,the gas-sensing patterns of methanol were qualitatively distinguished from those of water vapor in a binary mixture condition,suggesting that the proposed scheme is capable of differentiating a gas from the realistic scenario of an ambient environment with background humidity.As such,this work offers a new class of gas-sensing schemes using a single GFET without multiple functional materials toward miniaturized e-noses.Takeshi Hayasaka Albert Lin Vernalyn C.Copa Lorenzo P.Lopez Jr Regine A.Loberternos Laureen Ida M.Ballesteros Yoshihiro Kubota Yumeng Liu Arnel A.Salvador Liwei Lin 2020Microsystems & Nanoengineering2020,6,1:2
9Proteome analysis of human mesenchymal stem cells undergoing chondrogenesis when exposed to the products of various magnesium-based materials degradation显示文摘Treatment of physeal fractures(15%–30%of all paediatric fractures)remains a challenge as in approximately 10%of the cases,significant growth disturbance may occur.Bioresorbable Magnesium-based implants represent a strategy to minimize damage(i.e.,load support until bone healing without second surgery).Nevertheless,the absence of harmful effects of magnesium-implants and their degradation products on the growth plate should be confirmed.Here,the proteome of human mesenchymal stem cells undergoing chondrogenesis was evaluated when exposed to the products of various Magnesium-based materials degradation.The results of this study indicate that the materials induced regulation of proteins associated with cell chondrogenesis and cartilage formation,which should be beneficial for cartilage regeneration.Adela Helvia Martínez Sánchez Maryam Omidi Marcus Wurlitzer Marceline Manka Fuh Frank Feyerabend Hartmut Schlüter Regine Willumeit-Römer Bérengère J.C.Luthringer 2019Bioactive Materials2019,4,1:2
10Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19.Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral 2021Cellular & Molecular Immunology2021,18,9:2

12High-resolution ex vivo analysis of the degradation and osseointegration of Mg-xGd implant screws in 3D显示文摘Biodegradable magnesium(Mg)alloys can revolutionize osteosynthesis,because they have mechanical properties similar to those of the bone,and degrade over time,avoiding the need of removal surgery.However,they are not yet routinely applied because their degradation behavior is not fully understood.In this study we have investigated and quantified the degradation and osseointegration behavior of two biodegradable Mg alloys based on gadolinium(Gd)at high resolution.Mg-5Gd and Mg-10Gd screws were inserted in rat tibia for 4,8 and 12 weeks.Afterward,the degradation rate and degradation homogeneity,as well as bone-to-implant interface,were studied with synchrotron radiation micro computed tomography and histology.Titanium(Ti)and polyether ether ketone(PEEK)were used as controls material to evaluate osseointegration.Our results showed that Mg-5Gd degraded faster and less homogeneously than Mg-10Gd.Both alloys gradually form a stable degradation layer at the interface and were surrounded by new bone tissue.The results were correlated to in vitro data obtained from the same material and shape.The average bone-to-implant contact of the Mg-xGd implants was comparable to that of Ti and higher than for PEEK.The results suggest that both Mg-xGd alloys are suitable as materials for bone implants.Diana Krüger Silvia Galli Berit Zeller-Plumhoff D.C.Florian Wieland Niccolo Peruzzi Bjorn Wiese Philipp Heuser Julian Moosmann Ann Wennerberg Regine Willumeit-Romer 2022Bioactive Materials2022,7,7:2
