Aberrant autophagy in vascular smooth muscle cells (VSMCs) is associated with the progression of vascular remodeling diseases caused by neointimal hyperplasia. Platelet-derived growth factor-BB (PDGF-BB)-induced vascular remodeling is accompanied by autophagy activation, however, the involvement of circular RNAs (circRNAs) remains unclear. Here, we show the role of PDGF-BB-regulated hsa_circ_0001304 (circ-1304) in neointimal hyperplasia and its potential involvement in VSMC autophagy, while also elucidating the potential mechanisms.

Bone tissue engineering is a promising field that aims to rebuild the bone tissue using biomaterials, cells, and signaling molecules. Materials like natural and synthetic polymers, inorganic materials, and composite materials are used to create scaffolds that mimic the hierarchical microstructure of bone. Stem cells, particularly mesenchymal stem cells (MSCs), play a crucial role in bone tissue engineering by promoting tissue regeneration and modulating the immune response.

Division of Pulmonary, Allergy, and Sleep Medicine, Mayo Clinic Florida, Jacksonville, FL, USA.
Objective: Thromboelastography (TEG) offers a point-of-care and comprehensive evaluation of the coagulation cascade, but its utility in predicting bleeding risk in Interventional Pulmonology (IP) procedures has not been thoroughly investigated. This study aims to evaluate the effectiveness of TEG in assessing bleeding risk in patients undergoing elective IP procedures.
Material And Methods: Retrospective study of patients who underwent elective IP procedures at Mayo Clinic (Jacksonville, FL, USA) from November 2022 to May 2024.
Utility of Thrombopoietin Receptor Agonists (TPO-RAs) for Prolonged Thrombocytopenia After CAR-T Cell Therapy.

Background: Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment landscape for various hematological malignancies. However, it is associated with a range of hematologic complications, including severe and often prolonged thrombocytopenia. Currently, there are no known effective preventative or management measures against CAR-T-induced thrombocytopenia.

Background: Post-acute COVID-19 Syndrome (PACS) occurs in some COVID-19 patients long after acute infection and significantly affects patients' health. However, the mechanism by which PACS develops is unknown. Myosin light chain 9 (Myl9), produced by activated platelets, plays a role in immune dysregulation and microthrombi formation during acute COVID-19.
