Summary: In this study, chitosan/Fe(III)/deferoxamine nanoparticles were prepared with a unimodal size distribution. These nanoparticles exhibited outstanding antibacterial activity in vitro and in vivo, surpassing that of commercial antibiotics ampicillin and gentamicin. Additionally, the nanoparticles were found to be non-toxic. The introduction of iron ions into the chitosan matrix increased the ability of the nanoparticles to disrupt the integrity of microorganism membranes, and the incorporation of deferoxamine greatly enhanced their membrane destruction effect.

Summary: Cytotoxicity assays are crucial for testing novel immunotherapies for cancer treatment. The Matador-Glo assay utilizes a thermostable variant of Click Beetle Luciferase for luminescence detection and is simple, fast, specific, sensitive, cost-efficient, and not labor-intensive. This assay can also be combined with the marine luciferase-based Matador assay for dual luciferase detection of cell death, and the target cells expressing Luc146-1H2 can be used for in vivo bioluminescence imaging applications.

Summary: This study aimed to compare the volatile phytocomposition of snow mountain garlic (SMG) with normal garlic and investigate its anti-Candida efficacy against multi-drug resistant isolates of Candida species. The results showed that SMG has superior fungicidal power against C. albicans and C. glabrata compared to normal garlic. GC-MS profiling revealed unique volatile compounds and higher saponins content in SMG. In-silico analysis identified a potential inhibitor in SMG, suggesting a plausible anti-Candida mechanism. This study provides valuable insights into the potential use of SMG as a fungal phytotherapy agent.

Summary: COVID-19 patients with happy hypoxia often have higher levels of nitric oxide (NO) compared to non-COVID-19 hypoxemics. Excessive production of reactive oxygen species (ROS) and oxidative stress decrease the level of NO, leading to mitochondrial dysfunction and hypoxia-mediated mortality in COVID-19. NO has a dual role of increasing oxygenation and inhibiting cytokine storm. Precise dosing of NO, along with NOS inhibitors, can help maintain optimal NO levels in patients. Monitoring NO levels is crucial in understanding the pathogenesis of COVID-19 and happy hypoxia.

Summary: The Omicron variant of SARS-CoV-2 exhibits altered peptide sequences in the spike protein, which may contribute to its higher infectivity compared to the original variant. Through analysis and in silico simulations, we predict that these alterations may affect the binding between the spike protein and the receptor Nrp1, potentially explaining the increased infectivity of the Omicron variant.
