Does epiblast-specific Snai1 deletion result in embryonic lethality due to multiple vascular defects?
These studies demonstrate that lethality in the Snai1-conditional mutant embryos is caused by multiple defects in the cardiovascular system.
This study suggests that PHECPs cannot accurately identify crash victims with positive serum alcohol concentrations. Selection bias and retrospective design are significant limitations of this study. Future studies should develop and evaluate methods to improve PHECPs' accuracy in assessing alcohol use in motor-vehicle crash victims.
