However, the relationship between ligaments surrounding the joint and joint instability remains unclear.

Acute abdomen by red degeneration of a parasitic leiomyoma: A case report and literature review.

A 43-year-old woman, with a history of uterine fibroids and multiple myomectomy, presented with acute lower abdominal pain. Computed tomography revealed multiple tumors, including a high-density mass in the left lower abdomen indicative of a parasitic leiomyoma undergoing red degeneration. This uncommon condition is due to acute occlusion, often caused by peripheral venous thrombosis at the fibroid edge.

Functionalized Polyamine Synthesis with Photoredox Catalysis.

Polyamines, such as putrescine and spermidine, are pivotal in various biological processes across living organisms.
