Cardiac arrest secondary to pulmonary embolism treated with extracorporeal cardiopulmonary resuscitation: Six case reports.

Background: Massive pulmonary embolism (PE) results in extremely high mortality rates. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) can provide circulatory and oxygenation support and rescue patients with massive PE. However, there are relatively few studies of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with cardiac arrest (CA) secondary to PE.

Deciphering the transcriptional regulation of microRNA genes in humans with ACTLocater.

Understanding the transcriptional regulation of microRNAs (miRNAs) is extremely important for determining the specific roles they play in signaling cascades. However, precise identification of transcription factor binding sites (TFBSs) orchestrating the expressions of miRNAs remains a challenge. By combining accessible chromatin sequences of 12 cell types released by the ENCODE Project, we found that a significant fraction (~80%) of such integrated sequences, evolutionary conserved and in regions upstream of human miRNA genes that are independently transcribed, were preserved across cell types.
