Reactive oxygen species are important components in cancer treatments

Reactive oxygen species (ROS) are highly reactive chemicals which contain oxygen radicals. Hypochlorous acid, peroxides, superoxide, singlet oxygen, alpha-oxygen and hydroxyl radicals are the major examples of ROS, which are familiar to persons from many walks of life as they are used in many domestic and industrial processes.

SARS-CoV-2 causes ER-stress-activated unfolded protein response leading to cell death

A new study describes the varying ways in which the virus co-opts the machinery of the host cell following infection to evade or modulate the host immune response, alter the pattern of translation of viral proteins, and the release of new viral particles.

Researchers reanalyze COVID RECOVERY trial data on tocilizumab

A Bayesian analysis of the RECOVERY trial suggests the immunosuppressive drug tocilizumab can reduce deaths in hospitalized COVID-19 patients taking corticosteroids as well as patients on oxygen or non-invasive ventilation and likely increases hospital discharge rates. However, it is not clear if patients on invasive ventilation also benefit.
