Results from these studies indicate that the mouse PPARα is required to mediate hepatocarcinogenesis induced by GW7647 in mice and that activation of the human PPARα with GW7647 in PPARA-humanized mice are diminished compared to wild-type mice. Ppara-null and PPARA-humanized mice are valuable tools for examining species differences in the mechanisms of PPARα-induced hepatocarcinogenesis, but background levels of liver cancer observed in aged Ppara-null and PPARA-humanized mice must be considered when interpreting results from studies that use these models. These results also demonstrate that early life exposure to a potent human PPARα agonist does not enhance sensitivity to hepatocarcinogenesis. We aimed to evaluate the characteristics and outcomes of critically ill children managed in an intensive care unit because of coronavirus disease (COVID-19) pneumonia with respiratory support requirements. We performed a single-center retrospective observational study in a pediatric intensive care unit (PICU) with 32 beds in Ankara City Hospital, Ankara, Turkey, from 13 March 2020 to 31 December 2020. Patients who needed positive-pressure ventilation (PPV) therapy for COVID-19 pneumonia were included in the study. Demographic, clinical and laboratory data were extracted from the patients' electronic medical records. As outcomes, the hospitalization rate of all pediatric patients diagnosed as having with COVID-19 by Polymerase Chaın Reactıon(PCR), PICU admission rate for COVID-19 pneumonia among all hospitalized patients, PPV support rate, intensive care hospitalization duration (days), total hospitalization duration (days), survival rate and tracheotomy requirement were evaluated. During the study period, 7033 children tested positive for COVID-19 in PCR tests. Of these patients, 1219 were hospit
