Furazolidone (FZd), a nitrofuran antibiotic used for the treatment of bacterial and protozoal illnesses, generates apprehensions about its potential toxicity and mutagenicity. The swift and dependable identification of FZd in food and biological specimens is essential for public health and regulatory adherence. This study presents a novel electrochemical sensor using a glassy carbon electrode (GCE) modified with a cobalt-based metal-organic framework (Co-MOF) and carbon black (CB) composite (Co-MOF@CB/GCE) for the sensitive detection of FZd. The Co-MOF@CB composite enhances electron transport and expands the electroactive surface area. Characterization investigations confirmed the successful fabrication of the Co-MOF@CB/GCE sensor. Electrochemical analyses revealed an extensive detection range (0.4–610 μmolL −1 ) and a minimal detection limit (0.0875 μmolL −1 ). The sensor exhibited great repeatability, stability, and selectivity, demonstrating efficient FZd detection in milk, honey, and chicken. This sensor provides a reliable, economical tool for FZd detection in regulatory and public health contexts.

The objectives of this study were to investigate the biocompatibility and hemostatic efficacy of silk fibroin nanofibrils (SFNFs). Unlike a conventional dialysis/freeze-drying process, SFNFs were prepared using a novel shear-induced phase-separation method. The morphology, particle size distribution, protein secondary structures, and crystalline structures of the resulting SFNFs were respectively investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), laser diffraction (Ld), Fourier-transform infrared (FTIR) spectroscopy, and x-ray diffraction (XRd) deconvolution analyses. Polar and non-polar extractants of SFNFs under a bath ratio of 0.2 g/mL were collected after individually soaking them into 0.9% normal saline and cottonseed oil. In vitro hemolysis ratios, biocompatibility, and sensitization tests were carried out. Then, the hemostatic efficacy was assayed using a rat liver punch biopsy model. Compared to dialyzed/freeze-dried SF, the harvested SFNFs revealed high surface area in morphology. The median particle size distribution, d50, was 294 μm for SFNFs. Shear-induced hydrogen bonding, crystallization, and phase separation tended to give the SFNFs a high crystalline index (CI) and degree of crystallinity (dC). The hemolysis ratio of SFNFs was 0.86 ± 0.40%, and it was classified as being non-hemolytic (0%∼2%). The test results of toxicity and skin sensitization were both negative. The hemostasis time for SFNFs (2.8 ± 0.6 min) was statistically less than that of oxidized cellulose (4.3 ± 0.9 min) (p © 2023 Elsevier B.V.

Taoyuan City 320315 Taiwan

In this study, we synthesized an amidoximated polyacrylonitrile nanofiber membrane (P-Oxime). Subsequently, we grafted reactive green 19 (RG19) dye onto its surface, resulting in the formation of the P-Oxime-RG19 membrane. Further enhancement was achieved by physically attaching poly(hexamethylene biguanide) hydrochloride (phMB) to the P-Oxime-RG19 membrane, leading to the formation of the P-Oxime-RG19-phMB membrane. Extensive characterization of the nanofiber membranes was conducted, focusing on crucial physical and mechanical properties such as functional group content, morphology, and thermostability. The optimization of various modification conditions, including initial dye and phMB concentrations, duration, temperature, and nitrile group conversion to oxime concentrations, played a pivotal role in achieving superior antibacterial performance in P-Oxime-RG19-phMB nanofiber membranes. In-depth analyses involved the application of kinetic and equilibrium thermodynamic models to unravel the modification processes of RG19 dye and phMB in the nanofiber membranes. Under the carefully tuned optimal modification conditions, the P-Oxime-RG19-phMB nanofiber membrane exhibited remarkable antibacterial efficacy, achieving nearly 100% disinfection of E. coli . In addition to exploring its antimicrobial capabilities, we thoroughly examined the repeatability and biocompatibility of the nanofiber membranes. The results indicated not only the P-Oxime-RG19-phMB nanofiber membrane was a highly promising antibacterial material but also highlighted its potential for diverse applications, particularly in food and textile fabrication, owing to its exceptional performance and suitability.

This study aimed to integrate magnetic resonance imaging (MRI) and related somatosensory evoked potential (SSEP) features to assist in the diagnosis of spinal cord compression (SCC). MRI scans were graded from 0 to 3 according to the changes in the subarachnoid space and scan signals to confirm differences in SCC levels. The amplitude, latency, and time–frequency analysis (TFA) power of preoperative SSEP features were extracted and the changes were used as standard judgments to detect neurological function changes. Then the patient distribution was quantified according to the SSEP feature changes under the same and different MRI compression grades. Significant differences were found in the amplitude and TFA power between MRI grades. We estimated three degrees of amplitude anomalies and power loss under each MRI grade and found the presence or absence of power loss occurs after abnormal changes in amplitude only. For SCC, few integrated approach combines the advantages of both MRI and evoked potentials. However, integrating the amplitude and TFA power changes of SSEP features with MRI grading can help in the diagnosis and speculate progression of SCC. © 2023, The Author(s).

Until recently, sorafenib has been the only treatment approved by the U.S. Food and drug Administration for patients with advanced hepatocellular carcinoma (HCC). Some patients, however, exhibit resistance to this treatment and subsequently experience cancer progression, recurrence, or death. Therefore, identifying a new alternative treatment for patients with little or no response to sorafenib treatment is vital. In this study, we explored the therapeutic potential and underlying molecular mechanism of antrocinol ((3aS,4R,6aS,10aR)-4-(hydroxymethyl)-7,7-dimethyldecahydro-1H-naphtho[1,8a-c]furan-1-one) in patients with HCC. The results indicated that antrocinol was more therapeutically effective than antrocin, Stivarga, and sorafenib against HCC cell lines. Antrocinol also substantially suppressed the expression of KRAS-GTP, p-MEK1/2, p-ERK1/2, and p-AKT in the Huh7 cell line. Additionally, antrocinol-induced apoptosis in the Huh7 cell line, inhibited the formation of tumorspheres, and suppressed the expression of cancer stem cell markers Cd133, KLF4, Cd44, OCT4, SOX2, and c-Myc. Animal studies revealed that antrocinol alone considerably suppressed tumor growth in nonobese diabetic/severe combined immunodeficient mice inoculated with Huh7 tumorspheres. It also synergistically enhanced the anticancer effect of sorafenib, resulting in enhanced suppression of tumor growth (p < 0.001) and tumorsphere formation (p < 0.001). In tumor samples resected from mice treated with antrocinol alone or in combination with sorafenib, immunohistochemical analysis revealed an increase in BAX expression and a decrease in ERK and AKT protein expression. To the best of our knowledge, this is the first report of the anti-HCC activity of antrocinol. With its higher therapeutic efficacy than that of sorafenib, antrocinol is a candidate drug for patients with HCC who demonstrate little or no response to sorafenib treatment. © 2022 Elsevier B.V.

Plastic pollution is a widespread issue that poses a threat to agroecosystems. Recent data on microplastic (MP) pollution from compost and its application to soil have highlighted the potential impact of micropollutants that may be transferred from compost. Thus, we aim with this review to elucidate the distribution-occurrence, characterization, fate/transport, and potential risk of MPs from organic compost to gain comprehensive knowledge and mitigate the adverse impacts of compost application. The concentration of MPs in compost was up to thousands of items/kg. Among micropollutants, fibers, fragments, and films are the most common, with small MPs having a higher potential to absorb other pollutants and cause harm to organisms. Various synthetic polymers, including polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), polyester (PES), and acrylic polymers (AP), have been widely used of plastic items. MPs are emerging pollutants that can have diverse effects on soil ecosystems, as they can transfer potential pollutants from MPs to compost and then to the soil. Following the microbial degradation scheme, the transfer chain from plastics to compost to soil can be broken down into main stages, i.e., colonization - (bio)fragmentation - assimilation - and mineralization. Microorganisms and adding biochar play an essential role during composting, which can be an effective solution to enhance MP degradation. Findings have shown that stimulating free radical generation could promote the biodegradation efficacy of MPs and possibly remove their occurrence in compost, thereby reducing their contribution to ecosystem pollution. Furthermore, future recommendations were discussed to reduce ecosystem risks and health challenges.

In today's era, nanoparticles (NPs) have become an integral part of human life, finding extensive applications in various fields of science, pharmacy, medicine, industry, electronics, and communication. The increasing popularity of NP usage worldwide is a testament to their tremendous potential. However, the widespread deployment of NPs unavoidably leads to their release into the environmental matrices, resulting in persistence in ecosystems and bioaccumulation in organisms. Understanding the environmental behavior of NPs poses a significant challenge due to their nanoscale size. Given the current environmental releases of NPs, known negative consequences, and the limited knowledge available for risk management, comprehending the toxicity of NPs in ecosystems is both awaiting and crucial. The present review aims to unravel the potential environmental influences of nano-scaled materials, and provides in-depth inferences of the current knowledge and understanding in this field. The review comprehensively summarizes the sources, fate, transport, toxicity, health risks, and remediation solutions associated with NP pollution in aquatic and soil ecosystems. Furthermore, it addresses the knowledge gaps and outlines further investigation priorities for the sustainable control of NP pollution in these environments. By gaining a holistic understanding of these aspects, we can work toward ensuring the responsible and sustainable use of NPs in today's fast-growing world.

Microchemical Journal 2024年 200卷

作者： deepak dabur Muhammad Arshad Sanwal Piracha Hui-Fen Wu Department of Chemistry National Sun Yat-Sen University Kaohsiung 70 Lien-Hai Road Kaohsiung 80424 Taiwan International Ph.D. Program for Science National Sun Yat-Sen University Kaohsiung 80424 Taiwan Institute of Medical Science and Technology National Sun Yat-Sen University Kaohsiung 80424 Taiwan Institute of Precision Medicine College of Medicine National Sun Yat-Sen University Kaohsiung 80424 Taiwan School of Pharmacy College of Pharmacy Kaohsiung Medical University Kaohsiung 80708 Taiwan School of Medicine College of Medicine National Sun Yat-Sen University Kaohsiung 80424 Taiwan

We propose an ultrasensitive and cost-effective novel fluorometric approach for effective detection of cysteamine/cancer marker. The synthesis of the 2d nanomaterial is accomplished via the solvothermal process using the ultrasound system which is termed as the two dimensional solvothermal synthesis of ultrasound (2d-STSUS). 2d Hexagonal boron nitride (hBN) has emerged as a promising material for sensing applications due to its exceptional properties like broad bandgap and high thermal stability makes it ideal for application in a wide range of sensors and biosensors. Since hBN cannot effectively absorb or emit light because of broad band gap, it cannot produce fluorescence. On the contrary, using W-doped hexagonal boron nitride nanosheets (hBNW), we were able to successfully increase the method's selectivity, sensitivity, and easy usage by fusing the unique properties of W metal with hBN. For the first time, hBNW nanosheets exhibited a clear blue color transition and were effectively employed to detect varied levels of cysteamine in human urine and aqueous samples. When combined with hBNW nanosheets, cysteamine has excellent outcomes among other drugs and neurotransmitters. The linearity value R 2 = 0.9991 for aqueous was observed in the range of 1 nM to 28 nM and the detection limit was 0.0936 nM under ideal conditions. Additionally, quantification tests were conducted on human serum and urine samples for real sample analysis, yielding R 2 values of 0.9961 and 0.9958, respectively.
