Medical Communication Services after Traumatic Spinal Cord Injury.

It is difficult to assess and monitor the spinal cord injury (SCI) because of its pathophysiology after injury, with different degrees of prognosis and various treatment methods, including laminectomy, durotomy, and myelotomy. Medical communication services with different factors such as time of surgical intervention, procedure choice, spinal cord perfusion pressure (SCPP), and intraspinal pressure (ISP) contribute a significant role in improving neurological outcomes. This review aims to show the benefits of communication services and factors such as ISP, SCPP, and surgical intervention time in order to achieve positive long-term outcomes after an appropriate treatment method in SCI patients.

Diverse preparation methods for small intestinal submucosa (SIS): Decellularization, components, and structure.

The native extracellular matrix (ECM) biomaterial derived from small intestinal submucosa (SIS) is widely applied in tissue engineering for tissue repair and regeneration. SIS ECM is obtained through physical and chemical methods to remove the intrinsic cells, which would otherwise cause adverse immune reactions when the SIS ECM is implanted into the host body. Several research teams have reported diverse SIS decellularization methods.
