Background: The current synthetic strategies for carbon dots (CDs) are usually time-consuming, rely on complicated processes, and need high temperatures and energy. Recent studies have successfully synthesized CDs at room temperature. Unfortunately, most CDs synthesized at room temperature are obtained under harsh reaction conditions, prepared using aromatic precursors, or need a long time to generate.

Aim: To assess the management of penile curvature correction in PD patients undergoing IPP procedures within a large multinational, multicenter cohort.
Methods: A retrospective analysis was conducted on PD patients treated with IPP by 11 experienced prosthetic surgeons.
Article Synopsis
- The study aimed to analyze pre- and intraoperative factors influencing the integrity of corporal bodies after placing an inflatable penile prosthesis (IPP), focusing on the occurrence of intraoperative and postoperative complications.
- Researchers reviewed a database of over 5,400 IPP surgeries conducted between 2016 and 2021, identifying significant predictors for complications linked to corporal integrity.
- Key predictors for complications included revision surgery, older age, and medical conditions like coronary artery disease or peripheral vascular disease, indicating the need for consideration of these factors during IPP placement to reduce risks.
Article Synopsis
- The study investigates the necessity of frozen section during sentinel lymph node biopsy (SLNB) for early breast cancer, highlighting that while it prevents a second surgery, it has its drawbacks.* -
- In a retrospective analysis of 147 patients at Salmaniya Medical Complex, the frozen section showed an 84.6% sensitivity with a 15.4% false-negative rate, and only a small percentage required immediate axillary dissection.* -
- The findings suggest that routine frozen section is often unnecessary, indicating that permanent section alone can maintain quality care in most early breast cancer cases.*
Two-dimensional (2D) culture models and animal experiments have been widely used to study the pathogenesis of periodontal and peri-implant diseases and to test new treatment approaches. However, neither of them can reproduce the complexity of human periodontal tissues, making the development of a successful 3D oral mucosal model a necessity. The soft-tissue attachment formed around a tooth or an implant function like a biologic seal, protecting the deeper tissues from bacterial infection.
