Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

Ibrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

The epidemiology and pathogenesis of uterine fibroids

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Uterine fibroids, or leiomyomas, are the most common benign tumors of the female reproductive tract, ultimately affecting a majority of women worldwide, primarily during their reproductive years. While their origin appears genetic, manifesting in monoclonal tumors, diverse features and mechanisms contribute to their growth and further ...

Effects of 1267 nm Illumination on Microcirculation Regulatory Mechanisms

Journal of Biophotonics, EarlyView.
The question of activation of blood flow regulatory mechanisms during laser illumination remains open to date. This study showed the effect of laser exposure on the microcirculatory bed, which appears in the form of endothelium‐dependent vascular activity.
