Use of Magnetic Resonance Imaging for Postoperative Radiation Therapy Planning in Patients with Carbon Fiber-Reinforced Polyetheretherketone Instrumentation.

Purpose: Carbon fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation is being used more frequently in the spinal oncology landscape. Better visualization with this material allows for more precise postoperative stereotactic body radiation therapy (SBRT) planning using either computed tomography (CT)-myelography or magnetic resonance imaging (MRI) studies. We compared the dosimetric planning equivalencies and outcomes.

Comparative Anatomic Study Between Intradural Suboccipital Retrosigmoid and Extradural Transzygomatic Middle Fossa Approaches to Expose the Trigeminal Nerve.

Background: Meckel cave tumors are relatively rare, especially trigeminal nerve (TN) schwannomas. These tumors frequently project through the trigeminal pore, occupying the middle and posterior fossae. The most used routes to this region are the suboccipital retrosigmoid intradural approach (SORSA) and the transzygomatic middle fossa approach (TZMFA).

Effects of L-alanyl-glutamine upon the blood and kidney biochemical parameters in the rat hind limb model of ischemia/reperfusion.

Purpose: To investigate the effects of l-alanyl-glutamine (Ala-Gln) intragastric administration upon blood and kidney metabolic parameters alterations in rats subjected to ischemia/reperfusion of hind limb.

Methods: Forty-eight male rats were randomized in 2 groups offered via gavage either saline 2.0 mL (G-1) or Ala-Gln solution 0.
