Electrosynthesis of bismuth nanodendrites/gallium nitride electrode for non-enzymatic hydrogen peroxide detection.

Bismuth nanodendrites (BiNDs) were electrodeposited on planar gallium nitride (GaN) electrode via a differential pulse voltammetric technique to fabricate the non-enzymatic hydrogen peroxide (HO) sensor. SEM images revealed that the as-obtained BiNDs had numerous dendrite sub-branches, whose diameters ranged from 136 to 152nm. The BiNDs/GaN electrode showed linear amperometric responses for HO in the concentration range from 10µM to 1mM with the sensitivity of 60.

Effectiveness of a depression disease management program in improving depression and work function--a pilot study.

Objective: We examined whether there were differences in depression and work function outcomes among primary care and specialty mental health patients treated by the Michigan Depression Outreach and Collaborative Care (M-DOCC), a depression care management program, developed by the University of Michigan Depression Center. In addition, we examined the relationship between depressive symptoms and workplace functioning among M-DOCC enrollees over time.

Method: We used mixed model and logistic regression analyses.
