Evaluation of Mono and Bimetallic Ferrocene-Based 1,2,3-Triazolyl Compounds as Burning Rate Catalysts for Solid Rocket Motor.

We reported mono and bimetallic ferrocene-based 1,2,3-triazolyl compounds as potential burning rate catalysts in their neutral and ionic forms. All complexes reported here were characterized using H and C NMR, elemental analysis, and Mössbauer spectroscopy, which was performed for neutral and oxide compounds. The complexes present quasireversible redox potentials with higher oxidative ability than ferrocene and catocene under the same conditions.

Unrecognized Postoperative Opioid-Induced Movement Disorder: A Case Report.

A 22-year-old man, with a medical history significant for posttraumatic stress disorder and chronic pain, underwent ankle surgery at the United States Naval Hospital, Yokosuka, Japan. His immediate postoperative course was complicated by episodic muscle rigidity, necessitating admission for diagnostic evaluation. The differential was necessarily broad and included local anesthetic toxicity, medication mediated effect, seizures, serotonin syndrome, and malignant hyperthermia.

Genetic counseling and presymptomatic testing programs for Machado-Joseph Disease: lessons from Brazil and Portugal.

Machado-Joseph disease (MJD) is an autosomal dominant, late-onset neurological disorder and the most common form of spinocerebellar ataxia (SCA) worldwide. Diagnostic genetic testing is available to detect the disease-causing mutation by direct sizing of the CAG repeat tract in the ataxin 3 gene. Presymptomatic testing (PST) can be used to identify persons at risk of developing the disease.

Presymptomatic testing for neurogenetic diseases in Brazil: assessing who seeks and who follows through with testing.

Diagnostic tests are available to detect several mutations related to adult-onset, autosomal dominant, neurodegenerative diseases. We aimed to describe our experience in a presymptomatic testing program run by the Brazilian Public Health System from 1999 to 2009. A total of 184 individuals were eligible for presymptomatic testing due to a risk for spinocerebellar ataxia (SCA) - SCA3 (80%), Huntington's disease (11.
