SUMMARY is a major human pathogen. It can cause many types of infections, in particular bacteremia, which frequently leads to infective endocarditis, osteomyelitis, sepsis, and other debilitating diseases. The development of secondary infections is based on the bacterium's ability to associate with endothelial cells lining blood vessels.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Background: External volume expansion (EVE) devices has been demonstrated to enhance the survival of fat grafts. Decellularized adipose tissue (DAT) serves as a promising scaffold for adipose regeneration; however, the effectiveness of adipose regeneration in DAT remains limited, and the underlying mechanisms of its regeneration require further investigation.
Objective: This study explores the potential of EVE technology to enhance DAT-mediated adipogenesis by facilitating cellular recruitment and establishing a microenvironment conducive to adipose tissue regeneration.

Vascular function is impaired by conditions such as hypertension, dyslipidemia, and diabetes as well as coronary risk factors including age, smoking, obesity, menopause and physical inactivity. Measurement of vascular function is useful not only for assessment of atherosclerosis itself but also in many other aspects such as understanding the pathophysiology, assessing treatment efficacy, and predicting prognosis of cardiovascular events. It is therefore important to accurately assess the extent of vascular function.

Diabetic wounds present multiple functional impairments, including neurovascular dysregulation, oxidative imbalance, and immune dysfunction, making wound healing particularly challenging, while traditional therapeutical strategies fail to address these complex issues effectively. Herein, we propose a strategy utilizing dual-layer microneedles to deliver therapeutic gases by modulating neurovascular coupling and immune functions for diabetic wound treatment. The microneedle can respond to reactive oxygen species (ROS) in the diabetic microenvironment and subsequently generate oxygen (O) and nitric oxide (NO).
