Article Synopsis
  • HDL is well-known for its protective effects against atherosclerosis, but its role in heart failure (HF) is still unclear and debated.
  • * Research suggests that HDL may help protect the heart through its antioxidant, anti-inflammatory, and endothelial functions, with high levels of HDL-C linked to lower instances of HF.
  • * The primary protein in HDL, Apo A-I, and the enzyme PON-1 are key components in mediating HDL's protective effects, potentially influencing the progression of heart failure.

Despite standard treatment for non-small cell lung cancer (NSCLC) being surgical resection, cancer recurrence and complications, such as induction of malignant pleural effusion (MPE) and significant postoperative pain, usually result in treatment failure. In this study, an alginate-based hybrid hydrogel (SOG) is developed that can be injected into the resection surface of the lungs during surgery. Briefly, endoplasmic reticulum-modified liposomes (MSLs) pre-loaded with the signal transducer and activator of transcription 3 (STAT3) small interfering RNA and lidocaine hydrochloride are encapsulated in SOG.
