Team IHMC at the 2020 Cybathlon: a user-centered approach towards personal mobility exoskeletons.

Background: The past few decades have seen rapid advancements in exoskeleton technology, with a considerable shift towards applications involving users with gait pathologies. Commercial devices from ReWalk, Ekso Bionics, and Indego, mainly designed for rehabilitation purposes, have inspired the development of many research platforms aimed at extending capabilities for use as safe and effective personal mobility devices. The 2016 Cybathlon featured an impressive demonstration of exoskeletons designed to enable mobility for individuals with spinal cord injury, however, not a single team completed every task and only two completed the stairs.

Matrix-Bound Nanovesicles Recapitulate Extracellular Matrix Effects on Macrophage Phenotype.

The early macrophage response to biomaterials has been shown to be a critical and predictive determinant of downstream outcomes. When properly prepared, bioscaffolds composed of mammalian extracellular matrix (ECM) have been shown to promote a transition in macrophage behavior from a proinflammatory to a regulatory/anti-inflammatory phenotype, which in turn has been associated with constructive and functional tissue repair. The mechanism by which ECM bioscaffolds promote this phenotypic transition, however, is poorly understood.

Evaluation of an evidence-based intervention implemented with African-American women to prevent substance abuse, strengthen relationship skills and reduce risk for HIV/AIDS.

African-American females in the U.S. are disproportionately affected by HIV/AIDS, and a large majority of new infections in this population are attributed to heterosexual contact.

Applying the creating lasting family connections marriage enhancement program to marriages affected by prison reentry.

Divorce proportions are currently high in the US and they are even higher among those who are incarcerated with substance abuse problems. Although much research has examined marital interventions, only two studies have examined marital interventions with prison populations. There is some empirical evidence that incarcerated couples benefit from traditional marital therapy (O'Farrell and Fals-Stewart, 1999, Addictions: A comprehensive guidebook, New York, Oxford University Press).
