Changes in spatiotemporal gait patterns during flat ground walking and obstacle crossing 1 year after bariatric surgery.

Background: Obesity has a negative impact on motor function, leading to an increase in fall risk. Massive weight loss improves some aspects of gait on flat ground. However, we have little information about whether gait changes during flat-ground walking and during more complex motor tasks beyond flat-ground walking.

The Importance of Interdisciplinary Research Training and Community Dissemination.

Funding agencies and institutions are creating initiatives to encourage interdisciplinary research that can be more easily translated into community initiatives to enhance health. Therefore, the current research environment calls for interdisciplinary education and skills to create sustained partnerships with community institutions. However, formalized opportunities in both of these areas are limited for students embarking on research careers.

Diamagnetic Ru(2+) in Na2La2Ti2RuO10-x (0 < x < 2): A Series of Complex Oxides Prepared by Topochemical Reduction.

Reaction of the n = 3 Ruddlesden-Popper phase Na2La2Ti2RuO10 with a 5% H2/95% N2 atmosphere between 300 and 900 °C leads to the formation of phases of composition Na2La2Ti2RuO10-x (0 < x < 2) via topochemical reduction. Magnetization data collected from Na2La2Ti2RuO10-x samples in the range 0 < x < 1 show a rapid decline in susceptibility with increasing x, consistent with the conversion of S = 1, Ru(4+) centers at x = 0 to S = 0, Ru(2+) centers at x = 1. We believe this is the first report of diamagnetic Ru(2+) centers in an extended oxide phase.
