p53 oligomerization status as an indicator of sensitivity of p53-wildtype neuroblastomas to the combination of DNA damaging agent and Chk1 inhibitor.

Neuroblastomas are one of the most common types of solid tumors in infants and children and are responsible for approximately 15% of childhood cancer deaths. Neuroblastomas rarely have mutations in p53, with less than 2% of NB containing mutations in p53, compared to up to 60% for other tumor classes. Previous studies on the therapeutic combination of a DNA damaging agent and checkpoint kinase 1 (Chk1) inhibitor have shown that DNA damage-induced cell cycle arrest can be specifically abrogated in p53-defective tumors.

The Answer to the Silent "Super Spreader": An Innovative Way to Manage Chest Drains on Coronavirus Patients With Active Air Leaks.

The risk of aerosol transmission has been a key factor for the rapid dissemination of the coronavirus pandemic. Transportation of coronavirus disease 2019 (COVID-19)-infected patients with active air leaks could expose unprotected health care personnel and other patients to aerosolized viral particles. We devised a way to avoid aerosolization while the chest tube drain is on water seal.
