Summary: In this study, the thermal and chemical non-equilibrium properties of arc plasmas in gas-metal arc-welding (GMAW) processes were investigated. A non-equilibrium model was developed to determine the influence of iron vapor on the arc plasma, highlighting the importance of iron vapor concentration in affecting the thermal equilibrium of the arc in GMAW processes.

Summary: We developed an in silico model to simulate the response of B16F10 melanoma cells to a helium atmospheric pressure plasma jet (APPJ) and doxorubicin drug (DOX). The simulation results showed that increasing plasma duration and DOX concentration resulted in increased cytotoxicity and a higher apoptosis probability compared to mitosis probability. Furthermore, combining plasma treatment and drug application enhanced cell cytotoxicity. This in silico model is valuable in the field of plasma medicine for understanding the response of different cancers to APPJ and cancer drugs.

Summary: Melanoma, with its high morbidity and mortality, has gained significant attention in recent years. Conventional treatment methods still have limitations, leading to the continuous development of novel approaches. Silver nanoparticles (AgNPs) have shown great potential in cancer research, particularly in melanoma treatment, due to their diverse abilities including antioxidant, antiproliferative, anti-inflammatory, antibacterial, antifungal, and antitumor effects. This review mainly focuses on the applications of AgNPs in preventing, diagnosing, and treating cutaneous melanoma, discussing the strategies of photodynamic therapy (PDT), photothermal therapy (PTT), and chemotherapy. Overall, AgNPs play an increasingly crucial role in cutaneous melanoma treatment and hold promising prospects for future applications.

Summary: In this study, a new method for determining both the gas temperature and the air fraction in non-thermal atmospheric helium plasmas is presented. This technique, based on UV-Atomic Emission Spectroscopy and the measurement of collisional broadening of specific emission lines, is particularly sensitive under low gas temperature conditions and suitable for diagnosing cold helium plasmas used in biomedical applications. Quantifying the air content is crucial for understanding the chemistry and clinical effects of these plasmas.
