Hybrid Repair of Ascending Aortic Intramural Hematoma and Arch Ulcer in a 74-Year-Old Woman - A Case Report.

BACKGROUND Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lacks an intimal tear, influencing both clinical presentation and treatment strategy. This report describes a 74-year-old hypertensive woman with type A IMH and a penetrating atherosclerotic ulcer (PAU), managed with a hybrid surgical approach that combines external Dacron wrapping of the ascending aorta and endovascular stenting of the aortic arch with in-situ fenestration of the supra-aortic arteries.

BCL6 Alleviates Hepatic Ischemia/Reperfusion Injury Via Recruiting SIRT1 to Repress the NF-κB/NLRP3 Pathway.

Outcomes included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs).

Exceptional Uptake, Limited Protein Expression: Liver Macrophages Lost in Translation of Synthetic mRNA.

Most gene therapies exert their actions via manipulation of hepatocytes (parenchymal cells) and the reasons behind the suboptimal performance of synthetic mRNA in non-parenchymal cells (NPC) such as Kupffer cells (KC), and liver macrophages, remain unclear. Here, the spatio-temporal distribution of mRNA encoding enhanced green fluorescent protein (Egfp), siRNA, or both co-encapsulated into lipid nanoparticles (LNP) in the liver in vivo using real-time intravital imaging is investigated. Although both KC and hepatocytes demonstrate comparable high and rapid uptake of mRNA-LNP and siRNA-LNP in vivo, the translation of Egfp mRNA occurs exclusively in hepatocytes during intravital imaging.
