Hypervitaminosis D leads to toxic effects, including hypercalcemia, which can cause severe damage to various organs. Fetuin-A, a glycoprotein with anti-inflammatory properties, may protect tissues from such damage. This study explores the role of Fetuin-A in mitigating hypervitaminosis D-induced damage in renal, hepatic, and cardiac tissues.

The development of small-diameter vascular grafts (SDVGs) still faces significant challenges, particularly in overcoming blockages within vessels. A key issue is the foreign-body response (FBR) triggered by the implants, which impairs the integration between grafts and native vessels. In this study, we applied an interfacial infiltration strategy to create a stable, hydrophilic, and passivated hydrogel coating on SDVGs.

Objective: To comprehensively understand the COVID-19 vaccination and infection status among patients with systemic sclerosis (SSc).
Methods: We conducted a retrospective analysis of patients diagnosed with SSc who were hospitalized in the Rheumatology and Immunology Department of Peking University People' s Hospital from January 2016 to March 2023. We collected detailed clinical cha-racteristics, vaccination status, and infection details through a systematic review of medical records and telephone follow-ups with the SSc patients.
A Novel Polymer Film to Develop Heart Valve Prostheses.

Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves. Advances in modern organic chemistry provide a wide range of polymers that can replace biological material in the production of valve prostheses.
