Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Understanding venous leg ulcers [PDF]

, 2018
Venous leg ulcers are open lesions between the knee and the ankle joint, which occur in the presence of venous insufficiency. There are theories to explain the causes of venous insufficiency, which ultimately leads to venous hypertension and can result ...

Revisiting Heinz-Lippman disease as a complication of chronic venous insufficiency

Journal of Vascular Surgery Cases and Innovative Techniques
Chronic venous insufficiency with and without ulceration is a common complication of varicose veins. Heinz-Lippmann disease is a potentially underreported complication of chronic venous insufficiency that involves heterotopic ossification of the peri ...

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Chronic venous insufficiency and post-thrombotic syndrome

, 2018
Chronic venous disease is a common problem with a significant impact upon both afflicted individuals and the healthcare system. Normal venous function requires patency of the axial veins with a series of venous valves, and muscle pumps.

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

Advanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Photoplethysmography in the assessment of venous insufficiency [PDF]

Journal of Vascular Surgery, 1987
Photoplethysmography has been used simultaneously with ambulatory venous pressure measurements to study 32 patients. Of the 62 limbs studied, 24 were normal, 20 had primary varicose veins, and 18 had deep valvular incompetence. The results indicate that the photoplethysmographic refilling time can provide a good separation between the three groups when

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution

Advanced Healthcare Materials, EarlyView.
Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.
