Abstract
Microwave-induced thermoacoustic (TA) imaging (MTAI) combines pulsed microwave excitation and ultrasound detection to provide high contrast and spatial resolution images through dielectric contrast, which holds great promise for clinical applications. However, artifacts caused by microwave dielectric effect will seriously affect the accuracy of MTAI images that will hinder the clinical translation of MTAI. In this work, we propose a deep learning-based method fully dense generative adversarial network (FD-GAN) for removing artifacts caused by microwave dielectric effect in MTAI. FD-GAN adds the fully dense block to the generative adversarial network (GAN) based on the mutual confrontation between generator and discriminator, which enables it to learn both local and global features related to the removal of artifacts and generate high-quality images. The practical feasibility was tested in simulated, experimental data. The results demonstrate that FD-GAN can effectively remove the artifacts caused by the microwave dielectric effect, and shows superiority in denoising, background suppression, and improvement of image distortion. Our approach is expected to significantly improve the accuracy and quality of MTAI images, thereby enhancing the diagnostic accuracy of this innovative imaging technique.

Abstract
Self-monitoring in tumor therapy is a concept that allows for real-time monitoring of the location and state of applied nanomaterials. This monitoring relies on dynamic signals, such as wave or magnetic signals, which vary in response to changes in the location and state of nanomaterials. Dynamic changes in nanomaterials can be monitored using dynamic signals, making it possible to determine and control the treatment process. Theranostic nanomaterials, which possess unique physical and chemical properties, have recently been explored as a viable option for self-monitoring. With the help of self-monitoring, theranostic nanomaterials can guide themselves to achieve region-selective treatment with higher controllability and safety. In this review, self-monitoring theranostic nanomaterials will be introduced in three parts according to their roles during therapy: tumor accumulation, tumor therapy, and metabolism. The limitations and future challenges of current self-monitoring theranostic nanomaterials will also be discussed.

Abstract
Nanoparticles have demonstrated noteworthy advancements in the management of various complex medical conditions, particularly cancer. In any case, these particles still harbor the potential to improve medicate conveyance to challenging, hard-to-reach loci. The interactions that occur between nanoparticles and red blood cells during their journey throughout the human body, despite exposure to blood, are still not fully understood. Assessment of the ability of nanoparticles to integrate with blood, characterized as nanoparticle compatibility, has been consistently overlooked and undervalued in its import. This review article investigates the effect of nanoparticles on red blood cells, while examining the compatibility of nanoparticles through the angle of hemolysis. This article discusses the main roles of erythrocytes and also provides an informed interpretation of several mechanisms involved in the interaction of nanoparticles and erythrocytes. Throughout the review, significant emphasis is attributed to the investigation of hemocompatibility studies concerning newly designed nanoparticles to promote their successful translation into clinical application. This review article examines the compatibility of magnetic nanoparticles in various fields, including regenerative medicine, cancer therapy, bioimaging, and drug delivery. Our results show that the chemical composition of the nanoparticle surface is a determining factor in hemocompatibility performance and interaction with blood cells. The surface properties of nanoparticles, namely surface charge, geometry, porosity, and surface functionalities of polymers or specific functional groups, represent key determinants of hemocompatibility.

Effect of Mn xO y Nanoparticles Stabilized with Methionine on Germination of Barley Seeds ( Hordeum vulgare L.). NANOMATERIALS (BASEL, SWITZERLAND) 2023; 13:nano13091577. [PMID: 37177122 PMCID: PMC10180524 DOI: 10.3390/nano13091577] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/28/2023] [Accepted: 05/05/2023] [Indexed: 05/15/2023]
Abstract
The aim of this research was to study the effect of MnxOy nanoparticles stabilized with L-methionine on the morphofunctional characteristics of the barley (Hordeum vulgare L.) crop. MnxOy nanoparticles stabilized with L-methionine were synthesized using potassium permanganate and L-methionine. We established that MnxOy nanoparticles have a diameter of 15 to 30 nm. According to quantum chemical modeling and IR spectroscopy, it is shown that the interaction of MnxOy nanoparticles with L-methionine occurs through the amino group. It is found that MnxOy nanoparticles stabilized with L-methionine have positive effects on the roots and seedling length, as well as the seed germination energy. The effect of MnxOy nanoparticles on Hordeum vulgare L. seeds is nonlinear. At a concentration of 0.05 mg/mL, there was a statistically significant increase in the length of seedlings by 68% compared to the control group. We found that the root lengths of samples treated with MnxOy nanoparticle sols with a concentration of 0.05 mg/mL were 62.8%, 32.7%, and 158.9% higher compared to samples treated with L-methionine, KMnO4, and the control sample, respectively. We have shown that at a concentration of 0.05 mg/mL, the germination energy of seeds increases by 50.0% compared to the control sample, by 10.0% compared to the samples treated with L-methionine, and by 13.8% compared to the samples treated with KMnO4.

Abstract
Imaging-guided percutaneous microwave thermotherapy has been regarded as an important alternative nonsurgical therapeutic strategy for hepatocellular carcinoma (HCC) that provides excellent local tumor control and favorable survival benefit. However, providing a high-resolution, real-time, and noninvasive imaging technique for intraoperative guidance and controlling postoperative residual tumor recurrence are urgent needs for the clinical setting. In this study, a cisplatin (CDDP)-loaded nanocapsule (NPs@CDDP) with microwave responsive property was prepared to simultaneously serve as a contrast agent of emerging thermoacoustic imaging and a sensitizing agent of microwave thermo-chemotherapy. Accompanying the enzymolysis in the tumor microenvironment, the NPs@CDDP responsively release l-arginine (l-Arg) and CDDP. l-Arg with excellent microwave-absorbing property allowed it to serve as a thermoacoustic imaging contrast agent for accurately delineating the tumor and remarkably increasing tumor temperature under ultralow power microwave irradiation. Apart from the chemotherapeutic effect, CDDP elevated the intracellular H2O2 level through cascade reactions and further accelerated the continuous transformation of l-Arg to nitric oxide (NO), which endowed the NPs@CDDP with NO-generation capability. Notably, the high concentration of intracellular NO was proved to aggravate lipid peroxidation and greatly improved the efficacy of microwave thermo-chemotherapy. Thereby, NPs@CDDP was expected to serve as a theranostic agent integrating the functions of tumor microenvironment-responsive drug delivery system, contrast agent of thermoacoustic imaging, thermal sensitizing agent, and NO nanogenerator, which was promising to provide a potential imaging-guided therapeutic strategy for HCC.
