Study Design: A retrospective study.
Purpose: We report our experience with 5-aminolevulinic acid (5-ALA)-assisted resection of spinal cord ependymomas in adults.
Overview Of Literature: Ependymoma is the most frequent primary spinal cord tumor in adults.
Background: TNM staging of cancer is used to establish the treatment and prognosis for cancer patients, and also allows the assessment of screening programmes and hospital performance. Collection of staging data is becoming a cornerstone for cancer registries. The objective of the study was to assess the completeness of T, N, M and stage grouping registration for all cancers in the Mallorca Cancer Registry in 2006-2008 and to explore differences in T, N, M and stage grouping completeness by site, gender, age and type of hospital.

Molecular dynamics simulations (MD) and quasi-elastic neutron scattering (QENS) measurements give new insights into the dynamical properties of this protein with respect to its eukaryotic and mesophilic homologue. Results obtained by MD are supported by QENS data and are interpreted within the framework of a fractional Brownian dynamics model for the characterization of protein relaxation dynamics.
