PAV-05 Naphthoquinone Potently Inhibit Zika Virus Replication in Infected Cells.

Background: Zika (ZIKV) is a virus transmitted by mosquitoes that can cause Guillain- Barré syndrome and congenital malformations like microcephaly. Given its explosive resurgence and the resulting epidemics in 2016, the search for effective antiviral drugs has become absolutely necessary.

Methods: In this study, we examined the potential of naphthoquinone derivatives that have a sulfonamide or sulfonate group to inhibit ZIKV replication in primary cultured neurons and in Vero cells.

Curcumin-coated iron oxide nanoparticles for photodynamic therapy of breast cancer.

Breast cancer is the deadliest cancer among women and its treatment using traditional methods leads the patient to experience adverse effects. However, photodynamic therapy (PDT) is a non-invasive therapy modality that works through a photosensitizing agent, which treating activated by a suitable light source, releases reactive oxygen species capable of treating cancer. Furthermore, recent research indicates that combining PDT and nanoparticles can enhance therapeutic effects.

Deletion of and genes in serovars induces a comparable immune response to wild-type infection in different chicken lineages.

It was previously reported that utilization of tetrathionate and 1,2-propanediol by spp. through the metabolic pathways encoded by and operons are related to overgrowth and out-competing microbiota in an anaerobic environment. However, recent knowledge demonstrated which strains in the absence of and genes provoke both higher intestinal colonization and spreading bacteria on faeces in relation to their respective wild-type strain, and generate more prominent inflammation as well.

MPXV: Update on Morphological and Morphogenesis Aspects Through Transmission and Scanning Electron Microscopies and 3D Reconstruction.

An unprecedented global outbreak caused by the monkeypox virus (MPXV) prompted the World Health Organization to declare a public health emergency of international concern on July 23, 2022. Therapeutics and vaccines for MPXV are not widely available, necessitating further studies, particularly in drug repurposing area. To this end, the standardization of in vitro infection systems is essential.

Silver Nanoparticles-Functionalized Textile against SARS-CoV-2: Antiviral Activity of the Capping Oleylamine Molecule.

COVID-19 disease, triggered by SARS-CoV-2 virus infection, has led to more than 7.0 million deaths worldwide, with a significant fraction of recovered infected people reporting postviral symptoms. Smart surfaces functionalized with nanoparticles are a powerful tool to inactivate the virus and prevent the further spreading of the disease.
