The impact of heparin and direct thrombin inhibitors on cell-penetrating polymer siRNA transfection.

Gene therapy using siRNA has become a promising strategy to achieve targeted gene knockdown for treatment of cardiovascular pathologies. However, efficient siRNA transfection often relies on cationic delivery vectors such as synthetic cell-penetrating polymers which are susceptible to interference by negatively charged molecules. Anticoagulants such as heparin, which is negatively charged and widely used in cardiovascular applications, may pose a significant barrier to effective siRNA delivery.

Extended 78% Hepatectomy in a Mouse Surgical Model.

Partial 2/3 hepatectomy in mice is used in research to study the liver's regenerative capacity and explore outcomes of liver resection in a number of disease models. In the classical partial 2/3 hepatectomy in mice, two of the five liver lobes, namely the left and median lobes representing approximately 66% of the liver mass, are resected en bloc with an expected postoperative survival of 100%. More aggressive partial hepatectomies are technically more challenging and hence, have seldom been used in mice.

Advancements in Omics and Breakthrough Gene Therapies: A Glimpse into the Future of Peripheral Artery Disease.

Peripheral artery disease (PAD), a highly prevalent global disease, associates with significant morbidity and mortality in affected patients. Despite progress in endovascular and open revascularization techniques for advanced PAD, these interventions grapple with elevated rates of arterial restenosis and vein graft failure attributed to intimal hyperplasia (IH). Novel multiomics technologies, coupled with sophisticated analyses tools recently powered by advances in artificial intelligence, have enabled the study of atherosclerosis and IH with unprecedented single-cell and spatial precision.
