Summary: Magnetic nanometer combined with microwave thawing (MN-MT) can be a novel solution for uneven and overheating challenges in microwave thawing (MT), while maintaining high thawing efficiency compared to conventional water immersion thawing (WT). This study applied MN-MT to thaw lychee fruit for the first time and evaluated it compared to WT, MT, and water immersion combined with microwave thawing (WI-MT). The results showed that MN-MT significantly reduced the thawing time of frozen lychee by 80.67%, 25.86%, and 18.83% compared to WT, MT, and WI-MT, respectively. MN-MT also enhanced the release of quercetin-3-O-rutinose-7-O-alpha-L- rhamnoside and protected thermal-sensitive compounds from degradation.

Summary: This study successfully identified fish freshness by combining hyperspectral imaging and multivariate data, establishing PLSR and MLSR models and optimizing algorithms. By generating spatial distribution maps of EC values at the pixel level, the freshness of fish fillets stored under different thawing methods can be effectively predicted.

Summary: Ultrasound assisted thawing (UAT) is an emerging thawing method that can shorten thawing time and improve the quality of thawed sea bass. The effect of frequency and power on UAT in aquatic products has not been systematically studied. This experiment evaluated the effect of frequency, alone or in combination, and different power levels during UAT on thawing time, water-holding capacity, quality, and myofibrillar protein structure in sea bass. The study found that UAT can improve the quality of thawed sea bass, especially at specific power and frequency settings.

Summary: The study found that magnetic nanoparticles combined with ultrasonic-microwave thawing (NUMT) can improve the water holding capacity of jumbo squid mantles, reduce oxidation levels, and effectively reduce protein aggregation and degradation, thus stabilizing the protein structure. NUMT treatment also resulted in a denser and more orderly muscle fiber structure, smoother surface, and smaller and uniformly distributed fiber network gaps.

Summary: The presence of magnetic nanoparticles (MNPs) suppresses ice nucleation and growth during freezing and thawing. In this study, the effects of MNPs-assisted cryogenic freezing integrated with MNP-combined microwave thawing (NNMT) on the thermodynamic and quality changes of salmon fillets were investigated. NNMT treatment significantly improved the storage stability, water holding capacity, texture, color, and other quality characteristics of salmon fillets, with minimal impact on their freezing-thawing quality.

Summary: This study retrospectively reviewed 81 patients with multifocal hepatocellular carcinoma who underwent combined hepatectomy and microwave ablation, finding an overall survival rate of 54% at 5 years. The major complication rate post-surgery was 10%, with certain factors like des-gamma-carboxy prothrombin level and tumor characteristics identified as independent risk factors for survival outcomes. The study concludes that the combined procedure is safe and feasible for selected patients with multifocal HCC.

Summary: The study found that microwave irradiation can rapidly thaw frozen soil, with the strength decreasing quickly, and the efficiency of microwave irradiation is 140 times higher than traditional conduction heating. Nuclear magnetic resonance tests revealed that the fundamental reason for thawing frozen soil is the presence of a certain amount of unfrozen water between ice and soil grains.

Summary: The study found that the pulsed electric field treatment affects lipid oxidation in fish samples, leading to yellowing of the fish flesh. However, the oxidative status quality of the sea bass samples remained acceptable under the specified standards. Moreover, protein oxidation was significantly influenced by electroporation.

Summary: The study showed that microwave combined with air convection thawing (MAT) was more effective in retaining the properties and tertiary structure of myofibrillar proteins (MPs) from porcine longissimus dorsi muscle compared to other thawing methods, making the properties of MPs in MAT closer to fresh meat. Additionally, there was a tighter interaction between water and muscle protein in MAT compared to fresh meat.

Summary: The ability to control neuronal mobility and organization is crucial for developing neuronal interfaces and therapeutic approaches. Magnetic forces offer a promising method for remote manipulation of neuronal cells, but the use of magnetic iron oxide nanoparticles as internal actuators may have adverse effects. In this study, we have developed a magnetic system based on streptavidin-biotin interaction to decorate cellular membrane with magnetic elements. By applying pre-designed magnetic fields, we demonstrated remote control of cell movement and formation of organized networks of cells using micro-patterned magnetic devices.

Summary: The effects of different thawing methods on the properties, oxidation, and structure of frozen mutton were investigated. The ultrasound combined with slightly acidic electrolyzed water thawing (UST) treatment showed significant improvements in myofibrillar protein (MP) properties, reduced protein aggregation, enhanced stability, and inhibited protein oxidation. UST treatment also minimized damage to MP secondary and tertiary structure compared to other thawing methods.
