Is fragmentation of embryos associated with both necrosis and apoptosis?
Fragments of human embryos exhibited various characteristics of necrosis, such as staining with PI, DNA fragmentation, rapid depletion of ATP, and harmful effects on neighboring blastomeres. We suggest that the fragmentation of embryos is closely associated with both necrosis and apoptosis. Whether this fragmentation is associated with primary or secondary necrosis remains to be elucidated.
Our results revealed that seroprevalence of SFTSV in healthy people in Laizhou County was not significantly different among age groups, but SFTS patients were mainly elderly people, suggesting that age is the critical risk factor or determinant for SFTS morbidity and mortality.
