The Feeling of Fatigue Scale for Brazilian Fighter Pilots.

Introduction: Fighter pilots are a population particularly vulnerable to developing mental fatigue, which puts the safety of military operations at risk. Although there is no gold standard tool for its assessment, Yoshitake's Feeling of Fatigue Scale (FFS) appears promising for application to fighter pilots as it has already been validated for Brazilian commercial airline pilots. The objective of this study was to evaluate the psychometric properties of the FFS in Brazilian fighter pilots.

Biodegradable seeds of holmium don't change neurological function after implant in brain of rats.

Aim: To evaluate the surgical procedure and parenchymal abnormalities related to implantation of ceramic seeds with holmium-165 in rats' brain.

Background: An effective method of cancer treatment is brachytherapy in which radioactive seeds are implanted in the tumor, generating a high local dose of ionizing radiation that can eliminate tumor cells while protecting the surrounding healthy tissue. Biodegradable Ho-ceramic-seeds have been addressed recently.
