Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

Advanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

Lactate‐Activated GPR132‐Src Signal Induces Macrophage Senescence and Aggravates Atherosclerosis Under Diabetes

Advanced Science, EarlyView.
Elevated lactate in diabetes activates the GPR132‐Src pathway in macrophages, inducing macrophage senescence and further enhancing foam cell formation. This mechanism exacerbates atherosclerotic progression. Abstract Diabetes is widely acknowledged as a significant risk factor for atherosclerosis, facilitating plaque formation through various ...

Coronary angioplasty in iatrogenic coronary artery stenosis

The Journal of Thoracic and Cardiovascular Surgery, 1983
Iatrogenic coronary artery stenosis as a serious complication of aortic valve procedures is a difficult condition to solve. We present a case in which both ostia were involved. As the patient refused reoperation, percutaneous transluminal coronary angioplasty (PTCA) was used.

Identification of Schwann Cells in Human Intracranial Arteries: Potential Regulatory Role in Atherosclerotic Plaque Progression

Advanced Science, EarlyView.
Schwann cells may facilitate intracranial plaque progression via neurovascular remodelingcting with vascular smooth muscle cells in atherosclerotic plaques, with the SPP1 ‐ ITGB1 signaling axis mediating this interaction as a novel mechanism. Abstract Intracranial atherosclerosis (ICAS), a common cause of ischemic stroke, remains a therapeutic ...
