Google Maps Timeline: An open-access digital tool to monitor walking abilities in people with multiple sclerosis.

Introduction: Gait impairment is common in multiple sclerosis (MS), but difficult to evaluate in clinical practice. In this proof-of-concept observational study, we compared walking ability recorded by Google Maps Timeline to conventional clinical measures in people with MS.

Methods: We used open-access Google Maps Timeline to record the total number of days with walking activity, walking distance, walking time, and walking speed.

Effect of thyroid state on rate and sites of H2O2 production in rat skeletal muscle mitochondria.

The purpose of this study was to investigate the effects of thyroid state on rates and sites of H(2)O(2) production in rat muscle mitochondria. With Complex I- and Complex II-linked substrates, hypothyroidism decreased and hyperthyroidism increased the rates of O(2) consumption during State 4 and State 3 respiration and the rates of H(2)O(2) release during State 4 respiration. During State 3, the rates of H(2)O(2) release were not affected by thyroid state.
