Clinical-Epidemiology Aspect of Inpatients With Moderate or Severe COVID-19 in a Brazilian Macroregion: Disease and Countermeasures.

COVID-19, also known as coronavirus disease 2019, is an infectious viral disease caused by SARS-CoV-2, a novel coronavirus. Since its emergence, its epidemiology has been explored; however, for some regions of the world, COVID-19's behavior, incidence, and impact remain unclear. In continental nations like Brazil, this lack of knowledge results in nonuniform control, prevention, and treatment measures, which can be controversial in some locations.

Tyrosine kinase inhibitor TKI-258 inhibits cell motility in oral squamous cell carcinoma in vitro.

Background: Oral squamous cell carcinoma is extremely invasive, and this behavior is regulated by binding of extracellular molecules to the cell membrane receptors. The TKI-258 inhibits phosphorylation of FGFRs VEGFRs and PDGFRs. Our aim was to analyze the effect of TKI-258 treatment in cell movement using SCC-4 cell line from human oral squamous cell carcinoma.
