Summary: In this study, a simple and label-free method using differential pulse voltammetry (DPV) was proposed for the sensitive detection of menthol. Silica microspheres (SiO2) were introduced for better modification and enrichment of ferrocene (Fc) on the electrode surface to improve detection sensitivity. The electrochemical signal of Fc was inhibited due to the inclusion action of Fc and ss-cyclodextrins (ss-CD), but showed remarkable recovery in the presence of menthol. The recovered electrochemical signal increased linearly with the concentration of menthol, providing a high sensitivity for quantitative detection.

Summary: Emerging multifunctional nanoparticulate formulations, with nano-meter scale size and surface chemistry, can act as therapeutic delivery agents and diagnostic tools for non-invasive real-time monitoring using imaging technologies. This study evaluated the selective uptake of 18 nm and 80 nm sized gold nanoparticles (AuNPs) by ovarian cancer (OC) cells in vitro, and found that the 18 nm AuNPs were taken up 4 times more by SKOV3 cells compared to OVCAR5 cells. Luteinizing hormone-releasing hormone (LHRH) was conjugated to the surface of the AuNPs, making them potential contrast agents for novel spectral photon-counting CT imaging technology and a promising approach for targeted therapy of ovarian cancer.

Summary: This study evaluated the effectiveness of the combination therapy of UV-4B and EIDD-1931 against SARS-CoV-2 beta, delta, and omicron BA.2 variants. The results demonstrated that the combination therapy significantly enhanced the antiviral activity against these three variants compared to monotherapy. The analysis using the Greco model also identified the interaction between UV-4B and EIDD-1931 as additive against the beta and omicron variants and synergistic against the delta variant.

Summary: The COVID-19 breakout had a devastating impact globally, resulting in millions of deaths and significant economic burdens. However, the determination of the SARS-CoV-2 genetic sequence and global efforts to develop potential vaccines have provided a glimmer of hope. Adenoviral vector-based vaccines have shown promise due to their higher immune response, better manufacturing processes, safety, efficacy, and manageable storage procedures. As of April 2022, the WHO has approved three adenoviral vector-based vaccines, among a total of 10 vaccines approved worldwide for COVID-19.

Summary: In a previous study, it was shown that the nucleoside analogue favipiravir (FAV) can inhibit Zika virus (ZIKV) replication in human-derived cell lines. This study aimed to explain the variation in FAV activity and investigate its mechanism of action and the host cell factors that contribute to tissue-specific differences in drug effect. The results revealed that FAV therapy caused an increase in mutations and the production of defective viral particles in all cell lines, with a higher proportion of defective particles released from HeLa cells. Overall, these companion papers highlight the lethal mutagenesis effect of FAV against ZIKV and demonstrate the influence of host cell factors on the activation and antiviral activity of nucleoside analogues.

Summary: This review discusses the potential of tailored graphene-based nanomaterials (GBNs) for the treatment of Parkinson's disease (PD). GBNs show promise in targeting mechanisms contributing to PD neurodegeneration, such as alpha-synuclein aggregation, autophagy, inflammation, and oxidative stress. Furthermore, GBNs can be applied in nanomedicine, regenerative medicine, and biosensors, but so far, their use is limited to computational and early-stage experimental studies, and their biocompatibility and safety need further evaluation.
