Endovascular interventions often fail due to restenosis, primarily caused by smooth muscle cell (SMC) proliferation, leading to intimal hyperplasia (IH). Current strategies to prevent restenosis are far from perfect and impose significant collateral damage on the fragile endothelial cell (EC), causing profound thrombotic risks. Nicotinamide adenine dinucleotide (NAD) is a co-enzyme and signaling substrate implicated in redox and metabolic homeostasis, with a pleiotropic role in protecting against cardiovascular diseases.

Background: Restenosis poses a significant challenge for individuals afflicted with peripheral artery diseases, often leading to considerable morbidity and necessitating repeated interventions. The primary culprit behind the pathogenesis of restenosis is intimal hyperplasia (IH), in which the hyperproliferative and migratory vascular smooth muscle cell (VSMC) accumulate excessively in the tunica intima. 6-Phosphogluconate dehydrogenase (6PGD), sometimes referred to as PGD, is one of the critical enzymes in pentose phosphate pathway (PPP).

Article Synopsis
  • Research is focused on finding safe alternatives for treating deep vein thrombosis (DVT) due to risks from traditional anticoagulants and thrombolytics.
  • Sonothrombolysis, which uses microbubbles and ultrasound along with thrombolytic agents, is being investigated to enhance the breakdown of blood clots.
  • In a study with mice, sonothrombolysis significantly reduced DVT volume from 52% to 20% after therapy, indicating its potential effectiveness in treating venous thromboembolism.

Deep vein thrombosis (DVT) is a life-threatening condition that can lead to its sequelae pulmonary embolism (PE) or post-thrombotic syndrome (PTS). Murine models of DVT are frequently used in early-stage disease research and to assess potential therapies. This creates the need for the reliable and easy quantification of blood clots.

Objectives: The objectives of the Rural Site Visit Project (SV Project) were to develop a successful model for engaging all 201 communities in rural British Columbia, Canada, build relationships and gather data about community healthcare issues to help modify existing rural healthcare programs and inform government rural healthcare policy.

Design: An adapted version of Boelen's health partnership model was used to identify each community's Health Care Partners: health providers, academics, policy makers, health managers, community representatives and linked sectors. Qualitative data were gathered using a semistructured interview guide.
