Counterregulatory roles of GLI2 and GLI3 in osteogenic differentiation via Gli1 expression.

J Cell Sci

January 2025

Department of Physiological Chemistry, Graduate School of Pharmaceutical Sciences, Kyoto University, Kyoto 606-8501, Japan.

The GLI1/GLI2/GLI3 transcription factors mediate Hedgehog (Hh) signaling, which is crucial for bone development. During intramembranous ossification, mesenchymal stem cells (MSCs) are directly differentiated into osteoblasts. Under basal and Hh pathway-stimulated conditions, primary cilia play essential roles in proteolytic processing of GLI3 to its repressor form (GLI3R), and in activation of GLI2.

Background: The Wolff-Parkinson-White pattern is a delta wave frequently detected in school-based cardiovascular screening programs in Japan. Although most children with Wolff-Parkinson-White pattern are asymptomatic, initial symptoms may include syncope or sudden death, necessitating accurate diagnosis and management. Delta waves can also indicate a fasciculoventricular pathway, which poses no risk and does not require management.

The novel case report of a temporary arrhythmia that developed after a positional change in a patient under general anesthesia emphasizes the possibility of potentially lethal cardiac arrhythmias that may develop owing to caudal movement of the peripherally inserted central venous catheter ([CVC] PICC) tip when changing patient positions. We present a case of temporary arrhythmia that developed after a positional change in a 44-year-old female patient scheduled for laparoscopic adrenalectomy under general anesthesia. She had undergone preoperative insertion of a PICC using an electrocardiogram (ECG)-guided tip confirmation system (TCS).

Transjugular transcatheter edge-to-edge mitral valve repair in a patient with functional mitral regurgitation: a case report.

Eur Heart J Case Rep

January 2025

Department of Cardiovascular Medicine, Sendai Kousei Hospital, 1-20 Tsutsumidori-amamiya, Aoba Ward, Sendai, Miyagi 9810914, Japan.

Article Synopsis
  • The transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is usually done via the transfemoral approach, but the transjugular approach can be a viable alternative when the former isn't possible.
  • A 57-year-old man with heart failure and severe functional mitral regurgitation could not undergo the transfemoral approach due to an occluded inferior vena cava, leading to the decision to use the transjugular technique instead.
  • The procedure was successful with no complications, significantly reducing the patient's mitral regurgitation, and he showed sustained improvement a year later.
