Evidence indicates that protein kinase C (PKC) plays a pivotal role in hypoxia-induced pulmonary hypertension (PH), but PKC isoform-specific protein expression in pulmonary arteries and their involvement in hypoxia-induced PH are unclear. Male SD rats (200-250 g) were exposed to normobaric hypoxia (10% oxygen) for 1, 3, 7, 14 and ...

Coronary artery perforation (CAP) after percutaneous coronary intervention is a rare, but serious complication. It can cause cardiac tamponade, acute myocardial infarction or death. The treatments of CAP involve prolonged balloon inflation, emergent surgery, coil embolization, and implantation of covered stent. We have successfully performed the emergent microcoil embolization in ...

Arteriovenous (AV) differentiation is a critical step during blood vessel formation and stabilization. Defects in arterial or venous fate lead to inappropriate fusion of vessels, resulting in damaging arteriovenous shunts. While many studies have unraveled the molecular underpinnings that drive AV fate, surprisingly, the spatiotemporal emergence of arteries and veins ...

Rectus sheath hematoma (RSH) is an uncommon clinical event usually associated with trauma or coagulation disorders. It can also occur spontaneously. RSH usually runs a benign course but it can present with hypovolemic shock. When conservative management fails, surgical exploration becomes mandatory. We propose a technique of emergency ligation of ...

BACKGROUND AND IMPORTANCE: Balloon-assisted coil placement is an important technique for coil embolization of broad-neck aneurysms. With this technique, we can prevent coil migration into a parent artery during a procedure. Complications of intraprocedural coil migration have been reported in the literature. However, delayed coil migration is extremely rare. We ...
