Analysis of Circulating Plasma MicroRNA Profile in Low-Grade and High-Grade Glioma – A Cross-Sectional Study

Background Glioma is the second most common type of brain tumor, accounting for 24% of all brain tumor cases. The current diagnostic procedure is through an invasive tissue sampling to obtain histopathological analysis, however, not all patients are able to undergo a high-risk procedure. Circulating microRNAs (miRNAs) are considered as promising biomarkers for glioma due to their sensitivity, specificity, and non-invasive properties. There is currently no defined miRNA profile that contributes to determining the grade of glioma. This study aims to find the answer for “Is there any significant miRNA that able to distinguish different grades of glioma?”. Methods This study was conducted to compare the expression of miRNAs between low-grade glioma (LGG) and high-grade glioma (HGG). Eighteen blood plasma samples from glioma patients and 6 healthy controls were analyzed for 798 human miRNA profiles using NanoString nCounter Human v3 miRNA Expression Assay. The differential expressions of miRNAs were then analyzed to identify the differences in miRNA expression between LGG and HGG. Results Analyses showed significant expressions in 12 miRNAs between LGG and HGG, where all of them were downregulated. Out of these significant miRNAs, miR-518b, miR-1271-3p, and miR-598-3p showed the highest potential for distinguishing HGG from LGG, with area under curve (AUC) values of 0.912, 0.889, and 0.991, respectively. Conclusion miR-518b, miR-1271-3p, and miR-598-3p demonstrate significant potentials in distinguishing LGG and HGG.

Ultrasensitive Room Temperature Formaldehyde Sensors Based on F Doped ZnO Nanostructures Activated by UV Light.

It is urgent to develop an ultrasensitive formaldehyde (HCHO) sensor that can operate at room temperature and has a low detection limit. Metal oxide semiconductors are excellent gas sensitive materials. Therefore, in this paper, we present the synthesis of fluorine (F) doped zinc oxide (ZnO) porous nanomaterials through a straightforward one-pot method with the optimization of F doping levels to achieve the detection of low concentrations of HCHO under UV light at room temperature. Under 375 nm UV light, the sensor exhibits a response value of 386% to 10 ppm of HCHO, which is 2.6 times higher than that of pure ZnO, and its detection limit is as low as 75 ppb. It has excellent selectivity, stability, and moisture resistance, which can meet the requirements of HCHO detection in daily life. Analysis reveals that doping ZnO with F not only increases the material's specific surface area but also introduces active sites. Furthermore, it alters the state of HCHO on the material's surface from physical adsorption to chemical adsorption. The above reasons together enhance the adsorption of HCHO on the gas sensitive material, thereby improving its gas sensitivity performance. Overall, this work demonstrates that F-doped ZnO is a potential material for ultrasensitive HCHO sensors and provides insights into the interpretation of the effect of doping on the gas sensitivity properties of materials.

Theoretical Calculation of Dissolved Gas in Transformer Oil Using the Gas Sensitive Properties of Sc- and Ti-Modified ZrS2.

To guarantee the secure functioning of the complete power system and minimize the risks associated with oil-filled transformers during their operation, it is greatly important to carry out gas sensing studies of dissolved gases in transformer research. Through the utilization of first-principles density functional theory calculations, the adsorption energy, electronic characteristics, and recuperation duration of ZrS2 modified with Sc and Ti were examined. The results show that compared to those of the initial ZrS2 material, the doping of TM atoms Sc and Ti significantly improved the adsorption properties of the material, and the adsorption of CO and C2H4 showed chemisorption. The adsorption capacity for gases decrease in the following order: C2H4 > CO > H2. The calculated recovery times indicate that Sc-ZrS2 and Ti-ZrS2 were ideal carbon monoxide sensing materials under the specific conditions. The results of this work can establish a fundamental rationale for the use of ZrS2 in sensing the conditions of oil-immersed transformers.

Cr3+-Activated Deep Trap Electron-Trapping Biphasic Mixture of Zn (Al,Ga)2O4 and Zn2GeO4 for Multilevel Information Storage by Trap Multiplexing and Wavelength Multiplexing.

Double wavelength emitting phosphors with hypersensitive thermal response are important for optical/thermal sensors and multiplexing optical data storage technology. However, it is a daunting challenge to develop multicolor electron-trapping materials with superheat sensitivity and anomalous quenching luminescence characteristics for information storage. Here, based on the selection of host lattice and the control of doping ion types, we have designed Mn2+- and/or Cr3+-activated persistent materials with excellent fluorescence properties. Among these phosphors, Mn,Cr co-activated biphasic mixture exhibits not only sensitive anomalous thermosensitive fluorescence properties but also multicolor and multimode fluorescence emission characteristics derived from Mn and Cr simultaneously. The corresponding multimode fluorescence mechanism is proposed based on afterglow energy transfer and deepening trap effect. Especially, based on the excellent fluorescence performances, these phosphors as information storage medium demonstrate multilevel information storage by a combination of the trap multiplexing and wavelength multiplexing technologies. The study here provides not only the ideas for designing and synthesizing new electronic materials but also a material foundation for the fourth generation of optical information storage and encryption.

JWST Observations of Young protoStars (JOYS)

Context. Due to the high visual extinction and lack of sensitive mid-infrared (MIR) telescopes, the origin and properties of outflows and jets from embedded Class 0 protostars are still poorly constrained. Aims. We aim to characterise the physical, kinematic, and dynamical properties of the HH 211 jet and outflow, one of the youngest protostellar flows. Methods. We used the James Webb Space Telescope (JWST) and its Mid-InfraRed Instrument (MIRI) in the 5–28 µm range to study the embedded HH 211 flow. We mapped a 0′.95 × 0′.22 region, covering the full extent of the blueshifted lobe, the central protostellar region, and a small portion of the redshifted lobe. We extracted spectra along the jet and outflow and constructed line and excitation maps of both atomic and molecular lines. Additional JWST NIRCam H2 narrow-band images (at 2.122 and 3.235 µm) provide a visualextinction map of the whole flow, and are used to deredden our data. Results. The jet-driving source is not detected even at the longest MIR wavelengths. The overall morphology of the flow consists of a highly collimated jet, which is mostly molecular (H2, HD) with an inner atomic ([Fe I], [Fe II], [S I], [Ni II]) structure. The jet shocks the ambient medium, producing several large bow shocks (BSs) that are rich in forbidden atomic ([Fe II], [S I], [Ni II], [Cl I], [Cl II], [Ar II], [Co II], [Ne II], [S III]) and molecular lines (H2, HD, CO, OH, H2O, CO2, HCO+), and is driving an H2 molecular outflow that is mostly traced by low- J, v = 0 transitions. Moreover, H2 0-0 S(1) uncollimated emission is also detected down to 2″-3″ (~650–1000 au) from the source, tracing a cold (T=200–400 K), less dense, and poorly collimated molecular wind. Two H2 components (warm, T =300–1000 K, and hot, T =1000–3500 K) are detected along the jet and outflow. The atomic jet ([Fe II] at 26 µm) is detected down to ~130 au from the source, whereas the lack of H2 emission (at 17 µm) close to the source is likely due to the large visual extinction (AV > 80 mag). Dust-continuum emission is detected at the terminal BSs and in the blue- and redshifted jet, and is likely attributable to dust lifted from the disc. Conclusions. The jet shows an onion-like structure, with layers of different size, velocity, temperature, and chemical composition. Moreover, moving from the inner jet to the outer BSs, different physical, kinematic, and excitation conditions for both molecular and atomic gas are observed. The mass-flux rate and momentum of the jet, as well as the momentum flux of the warm H2 component, are up to one order of magnitude higher than those inferred from the atomic jet component. Our findings indicate that the warm H2 red component is the main driver of the outflow, that is to say it is the most significant dynamical component of the jet, in contrast to jets from more evolved YSOs, where the atomic component is dominant.

Perovskite-structured LaFeO3 gas sensor modified by polyoxometalate electron acceptor with high sensitivity and low detection limit for acetone gas☆

Lanthanum ferrite is a representative perovskite-structured rare earth-based bimetallic oxide, which has been widely studied in magnetic materials, sensors, catalysts and batteries. Herein, we designed and prepared polyoxometalate electron acceptor decorated LaFeO3 gas-sensitive composite materials with one-dimensional nanoribbons morphology by electrospinning. The effects of different mass fraction of Keggin type phosphotungstic acid (PW12) on the gas-sensitive properties of LaFeO3 nanoribbons were investigated. The results show that the response value of LaFeO3/PW12 sensor to acetone gas first increases and then decreases with the increase of PW12 content. The LaFeO3/3%PW12 sensor exhibits a maximum response of 3.35 to 5 ppm acetone at 250 °C, a 2.6 times increase in response value and a 90 °C reduction in operating temperature compared to pure LaFeO3 nanoribbons. The LaFeO3/3%PW12 sensor exhibits good linear relation in ppb-level concentrations and the lowest detection concentration is 100 ppb. The sensors also show good repeatability in 6 tests and excellent long-term stability in 30 d. The improvement of the gas sensitive properties of the composite can be attributed to the synergistic effect between the two components. As an electron acceptor, PW12 promotes carrier migration between PW12 and LaFeO3, thereby improving the gas sensing performance of LaFeO3. This work promotes the practical application of polyoxometalate to promote rare earth-based gas sensitive materials in sensing field.

Role of Ti-6Al-4V addition in modulating crack sensitivity, solidification microstructure and mechanical properties of laser powder bed fused γ-TiAl alloys

Solidification cracking is still the primary challenge for laser powder bed fusion (LPBF) without high-temperature preheating of γ-TiAl alloys. Circumventing the peritectic reaction and promoting β-solidification by adding the β-stablizing elements have been proved to be an effective way to suppressing the crack formation. In this work, we attempted a more economic method to realize β-solidification via the addition of Ti-6Al-4V (TC4) pre-alloyed powder. The results showed that the TC4 addition successfully changed the solidification path from L→L+β→L+α→α→α+γ→α2+γ to L→L+β→β→α+β→α2+β/B2. As a result, the solidified microstructure was mainly comprised of primary α2 phase and small amount of retained β/B2 (8.5 %) phase distributed along the molten pool boundary. What's more important was that the TC4 addition led to a 44.6 % decrease in crack density. Contributions to low hot cracking sensitivity were found to mainly origin from the relatively lower cooling rate, higher fraction of low-angle grain boundaries (LAGBs) and smaller dendrite coalescence undercooling induced by the TC4 addition. Besides, the smaller temperature interval (10.63K) in the final solidification stage (0.90<fs < 0.94) for the TC4/TiAl alloy was also conducive to facilitate the liquid feeding and dendrite coalescence.

Effect of waste crab shell powder on matrix asphalt

Abstract In order to solve the problems of depleting petroleum asphalt resources and deteriorating pollution of marine products, a systematic study was carried out on the application prospect of waste crab shell (WS) powder as asphalt modifier. In this study, the physical properties of WS powder modified asphalt (WSA) were tested by blending different contents of WS powder into matrix asphalt; the high and low temperature rheological properties of WS powder modified asphalt were characterized by using Dynamic shear rheometer, Bending beam rheometer, and Multiple stress creep recovery test. In addition, the microscopic chemical properties and modification mechanism were analyzed by Differential scanning calorimetry, Fourier transform infrared spectroscopy, Atomic force microscopy, and Scanning electron microscope. It was shown that the WS powder enhanced the viscoelastic properties, temperature sensitivity properties, and permanent deformation resistance of asphalt. In addition, there was no obvious chemical reaction between the WS powder and the matrix asphalt, and no new chemical substances were generated; at the microscopic level, the WS powder and the matrix asphalt had good compatibility. In conclusion, the use of WS powder as a bio-based asphalt modifier to improve the resources and environmental issues have certain prospects.

Preparation of PAMgA/GL/GO antifreeze conductive hydrogel for wearable strain sensor based on physically cross-linked network

Conductive hydrogels have promising prospects in wearable strain sensor applications. However, the complex and diverse application scenarios put forward higher requirements on the conductivity, anti-freezing, tensile, self-healing, adhesion, and moisture retention properties of the conductive hydrogel. In this study, a polymagnesium acrylate/glycerol/graphene oxide (PAMgA/GL/GO) conductive hydrogel is prepared by free radical polymerization method, with magnesium acrylate (AMgA) as the polymer monomer, glycerol (GL) as the antifreeze filler, and graphene oxide (GO) as the conductive filler. Adding GL not only enhances the antifreeze properties of the composite hydrogels but also improves the moisture retention. The addition of GO increases the conductivity and the gauge factor (GF) of the composite hydrogels. When the GO content is 0.6 wt.%, the PAMgA/GL/GO conductive hydrogel demonstrates excellent properties of antifreeze, conductivity, self-healing, adhesion, and sensitivity. These excellent properties make it suitable as a wearable strain sensor for accurately monitoring human joint movements and subtle physiological signals.

The effects of ultrasound-assisted glycation on the allergenicity and functional properties of peanut proteins

This study investigated the effects of ultrasound-assisted glycation on the allergenicity and functional properties of peanut proteins. Results showed that ultrasound-assisted glycation increased the degree of glycation reaction of peanut proteins significantly (P < 0.05). ELISA results indicated that the binding of peanut allergens with serum immunoglobulin G (IgG) and immunoglobulin E (IgE) was significantly decreased (P < 0.05). Furthermore, secondary structure analysis revealed a significant increase in β-sheet content, alongside decreases in α-helix, β-turn, and random coil contents (P < 0.05). In addition, intrinsic fluorescence intensity, surface hydrophobicity, and ultraviolet (UV) spectra intensity were diminished (P < 0.05), indicating notable changes in both secondary and tertiary structures of peanut proteins. Moreover, emulsification property, antioxidant activity and in vitro digestibility of peanut proteins showed the most obvious improvements following ultrasound-assisted glycation, and the solubility was increased while turbidity was decreased significantly (P < 0.05). In conclusion, this study demonstrated that ultrasound-assisted glycation not only effectively reduced the allergenicity of peanut allergens, but also improved the overall functional properties of peanut proteins, and the changes in sensitization and functional properties might be closely related to structural changes. This study will provide a theoretical basis for the development of peanut products.

Synthesis of a Multi-Stimulus Responsive RGB Fluorescent Organic Molecule Based on Dark Through-Bond Energy Transfer Mechanism.

In this study, a novel multi-stimulus responsive RGB fluorescent organic molecule, RTPE-NH2, was designed and synthesized based on the combination of aggregation-induced emission tetraphenylethylene (TPE) luminophore and acid-responsive fluorescent molecular switch Rhodamine B. RTPE-NH2 exhibits aggregation-induced emission behavior, as well as UV irradiation-stimulus and acid-stimulus responsive fluorescence properties. It could emit orange-red (R), green(G), and blue(B) light in both solution and PMMA film under 365 nm excitation. The dark through-bond energy transfer (DTBET) mechanism was proposed and supported by control experiments and TD-DFT calculations. The synthesis and application of RTPE-NH2 could accelerate the development of organic smart materials with high sensitivity and excellent optical properties.

A novel 3D polymer gel dosimeter based on polymethyl methacrylate gel (PMMAG) for radiotherapy: Ultrasonic evaluation

This study investigates the characteristics of a novel polymer gel dosimeter (PMMAG) for radiotherapy applications, focusing on its radiation absorption and sensitivity properties. The PMMAG dosimeters were evaluated using both UV–vis spectrophotometry and ultrasonic techniques. The results of the study, UV–vis analysis revealed a significant increase in dose response with the introduction of a cross-linker, peaking at a monomer-to-cross-linker ratio of 5:3. Sensitivity analysis indicated optimal sensitivity at this ratio, with values reaching 0.021 a.u./Gy. Ultrasound evaluation showed that the speed of sound and attenuation coefficient demonstrated a linear relationship and a strong positive correlation with an increase in the applied radiation dose, with the highest sensitivity observed at 8 Gy. The optimal sample exhibited the highest dose-response values at both 4 Gy and 8 Gy doses. Sensitivity values ranged from 2.1 to 2.75. The ultrasonic measurements demonstrated a significantly larger dynamic range in dose response curves compared to UV–vis dose-response data. It is concluded that ultrasound shows great potential as a technique for the evaluation of polymer gel dosimeters. The PMMAG can be introduced as a novel dosimeter for ionizing radiation dosimetry, validated through both optical and ultrasound assessment methods. The consistent and reliable performance of the PMMAG dosimeters makes them suitable for various applications in radiation therapy.

Particle Focusing and Separation in the Low Aspect Ratio Serpentine‐Hook Shape Microarray

ABSTRACTIn recent years, researchers have been heavily focused on developing effective techniques for isolating and counting particles. Particle separation methods are enhancing disease point of care and treatment applications. Separation techniques not only increase the chance of early detection of illness but also greatly improve the success rate of treatment. This article introduces a passive microarray separator with a low aspect ratio (&lt;20%). By incorporating a low aspect ratio design, the flow inertial term is effectively diminished, leading to a creeping flow at the channel. This strategy results in negligible lift force and mixing effect on particles. Terminating the mentioned factors provides a channel with sensitive focusing properties. In the proposed research we enhanced a hook‐shaped geometry to increase regional centrifugal force. This configuration results in size‐base particle separation. An expansion was also added to improve the performance of the channel. To validate the functionality and limitations of the designed channel numerical simulation and experimental tests were conducted. To provide better insights into the low aspect ratio separator a numerical simulation using COMSOL Multiphysics has been established. The experiments indicated 91% purity at an input flow of 720 µL/min.

We examining the wave phenomena using 2D and 3D diagrams along with a projection of contour plots. Through the use of the computational program Mathematica, the research confirms the computed solutions to the WBBM equations.

Thermally Driven Spin Transport of Epitaxial FeRh Films with a Non-magnetic Pt Layer via the Longitudinal Spin Seebeck Effect.

FeRh has been demonstrated to be an important material for the observation of magnetic phase transitions, such as the first-order transition from an antiferromagnetic (AFM) to a ferromagnetic (FM) state, in response to changes in the temperature. This is because of the magnetic moment induced in Rh atoms above the magnetic phase transition temperature. In the present study, we focus on the longitudinal spin Seebeck effect (LSSE), which involves the generation of spin voltage as a result of a temperature gradient in FM materials or FM insulators, and experimentally assess the effect of the crystalline quality of FeRh films and the properties of the substrate on the LSSE thermopower during the FM-AFM phase transition. The measured LSSE thermopower of an epitaxial (110)-oriented FeRh film grown on an Al2O3 substrate is approximately 60 times higher than that of a polycrystalline FeRh film on a SiO2/Si substrate. This can be explained by the high magnetic sensitivity and superior FM properties of (110)-oriented epitaxial FeRh films. Furthermore, by comparing the transverse thermoelectric voltage for in-plane magnetized (IM) and perpendicularly magnetized (PM) configurations, we quantitively evaluate the contribution of the exclusive anomalous Nernst effect (ANE) to the LSSE signals in the FeRh/Al2O3 structure, finding it to be approximately 15-30% over a temperature range of 75-300 K. LSSE measurements in Pt/FeRh films are thus demonstrated to provide a versatile pathway for the development of thermoelectric power generation applications and other practical spintronics and neuromorphic computing devices.

Perovskite CsPbBr3 quantum dots enhanced In2O3 nanospheres for triethylamine detection at low temperature

In recent years, the vigorous industrial development of the country has brought about serious air pollution, and the development of low-temperature gas sensors with high response and short response/recovery time has become ideal for monitoring the industrial environment. This work demonstrates a composite gas sensor based on CsPbBr3 perovskite quantum dots (QDs) and In2O3 nanospheres for the detection of TEA gases at low temperatures. Compared with pure In2O3, the best responsive gas for the In2O3-CsPbBr3 QDs composite was triethylamine (TEA), with a response value of 52.92 at an optimal operating temperature of 60 °C. In addition, due to the sensitive optical properties of the CsPbBr3 QDs, UV irradiation of the In2O3-CsPbBr3 composites was performed, and the samples were found to have response values as high as 156.42. The In2O3-CsPbBr3 composite also has a short response recovery time (1/19 s), which is favorable for timely warning. The results of the gas-sensing experiments showed that the sensor has good sensitivity, reproducibility, and stability for triethylamine.

Fluorescence and temperature sensitive properties of Tb and Eu co-doped 8YSZ thermosensitive ceramic

Incorporating a small amount of rare-earth luminescent elements into thermal barrier coatings is currently the most promising method for determining the temperature distribution of engine blade coatings. In this study, Tb and Eu co-doped 8YSZ ceramic powder (8YSZ:Tb3+&Eu3+) was synthesized using chemical co-precipitation method, and the optimal powder was sintered into ceramic sheet through dry pressing. The phase, morphology, fluorescence properties and temperature sensitivity of 8YSZ:Tb3+&Eu3+ ceramic were studied. Results indicated that 8YSZ:Tb3+&Eu3+ was tetragonal with average grain size ranging from 22 to 28 nm. The luminescence intensity and lifetime of 8YSZ:Tb3+&Eu3+ both reach their maximum when the doping amount of Tb3+ is 1.5 mol%, with the existence of energy transfer from Tb3+ to Eu3+. And the forming processes has little influence on fluorescence performance of 8YSZ:Tb3+&Eu3+ materials. Meanwhile, 8YSZ:1.5Tb&1Eu ceramic reveals excellent temperature sensitivity. At 500 K, the relative sensitivities are 0.519% K-1 and 0.369% K-1 respectively for 8YSZ:1.5Tb&1Eu powder and sheet, while absolute sensitivities are 0.731% K-1 and 0.751% K-1. Consequently, 8YSZ:Tb3+&Eu3+ ceramic is a potential temperature detection material for practical applications.

Molecular regulation of lignin multi-level structure and conformational evolution for the self-powered fire alarm sensors

Many studies are still limited to focusing on the primary structure of biomass macromolecules, ignoring the impact of the multi-level structure of macromolecules and their conformational evolution on the high-value utilization of biomass. In this paper, a novel and clever strategy is designed and executed to regulate and immobilize the multi-level structure of lignin macromolecules. Lignin with different spatial conformations exhibits differences in physical properties and processability, despite their chemical primary structures being highly similar. In order to clearly and intuitively study the impact of multi-level structures, lignin-based carbon nanofibers (CFs) with high requirements for processing and precursor properties have been selected as the high-value utilization. The introduction of lignin with optimized multi-level structures effectively improves fiber morphology, uniform diameter, and flexibility. The resulting lignin-based CFs exhibit excellent refractoriness, stability, flame sensitivity (response time of only 1 s), and good energy storage properties (specific capacitance up to 226.1F/g). Furthermore, the CFs moist-electric generator has a high power generation efficiency, and the output voltage of a single device reaches 0.649 V and the output current is up to 160 μA. This work may explain a long-standing issue: why do lignin macromolecules with similar primary structures exhibit many differences in physical and processing properties, which is of great significance for promoting the industrial utilization of lignin macromolecules.

The Role of Starch Incorporation into Waterborne Acrylic-Hybrid Nanoparticles for Film-Forming Applications.

The use of biopolymers as an alternative to petroleum-based polymers offers a sustainable solution with benefits such as biodegradability and unique functionalities. In this study, starch/zein bioparticles (BPs) obtained by nanoprecipitation were employed to synthesize acrylic polymer/biopolymer waterborne nanoparticles with excellent film formation capability. These hybrid nanoparticle dispersions were obtained through a semibatch emulsion polymerization using the previously synthesized BPs as seed and variable monomeric formulations composed of butyl acrylate and methyl methacrylate. A synergetic effect between acrylic and biopolymer phases was evidenced where the incorporation of BPs had a fundamental role in improving sensitive properties, such as film blocking resistance, while attaining smooth films at room temperature. These excellent film-forming properties of starch/acrylic hybrid latexes without requiring the addition of formulation agents, which depict an important benefit from an environmental viewpoint, demonstrate that they represent a promising alternative for the development of a new generation of eco-friendly binders.
