Tissue Eng Regen Med
January 2025
College of Materials Science and Engineering, Hunan University, Changsha, 410072, People's Republic of China.
Background: Tissue engineering holds promise for vascular repair and regeneration by mimicking the extracellular matrix of blood vessels. However, achieving a functional and thick vascular wall with aligned fiber architecture by electrospinning remains a significant challenge.
Methods: A novel electrospinning setup was developed that utilizes an auxiliary electrode and a spring.
The serum level of sclerostin decreases in radiographic axial spondyloarthritis patients with fatty lesions.

Department of Rheumatology, the Fifth Affiliated Hospital of Sun Yat-sen University, 52 Meihua East Road, Zhuhai, People's Republic of China.
Background: Currently, the pathophysiology of new bone formation in radiographic axial spondyloarthritis (r-axSpA) remains unclear. Cellular elements and their secreted bone turnover markers might be one of the underlying mechanisms that drive the new bone formation. Our study aimed to investigate the role of bone turnover markers in r-axSpA patients with fatty lesions.

Naphthalene acetic acid (NAA) is an auxin plant growth regulator (PGR) and widely used to regulate the growth process of plants. As excessive NAA enter the environment, it damages the ecological environment and endangers human life and health. Layered bimetallic hydroxides (LDHs) are widely used for the adsorption of pollutants due to their large surface area and excellent structural properties.

Electronic address:
Electrical stimulation displayed tremendous potential in promoting nerve regeneration. However, the current electrical stimulation therapy required complex traversing wires and external power sources, which significantly limited its practical application. Herein, a self-powered nerve scaffold based on primary battery principle was gradient printed by laser additive manufacturing technique.
