Objective: To assess frailty and disability among older adults with and without diabetes or foot ulcers.

Method: A descriptive, comparative, controlled, multicentre study. Equal numbers of participants were allocated to three groups: (I) no diabetes/no foot ulcers (control), (II) diabetes but no foot ulcers or (III) diabetes and foot ulcers.

We report the electrochemical detection of estriol using carbon black nanoballs (CNB) decorated with silver nanoparticles (AgNP) as electrode material. Homogeneous, porous films on glassy carbon electrodes (GCE) were obtained, with diameters of 20 - 25nm for CNB and 5 - 6nm for AgNP. CNB/AgNP electrodes had increased conductivity and electroactive area in comparison with bare GCE and GCE/CNB, according to cyclic voltammetry and electrochemical impedance spectroscopy.

We report on the synthesis, characterization and applications of a Printex L6 carbon-silver hybrid nanomaterial (PC-Ag), which was obtained using a polyol method. In addition, we also highlight the use of Printex L6 nano-carbon as a much cheaper alternative to the use of carbon nanotubes and graphene. The silver nanoparticles (AgNP) were prepared directly on the surface of the Printex 6L carbon "nanocarbon" material using ethylene glycol as the reducing agent.

Objective: The purpose of this study was to examine the effectiveness of the Cognitive-Functional (Cog-Fun) intervention for young children with attention deficit hyperactivity disorder (ADHD).

Method: Nineteen children ages 5-7 yr diagnosed with ADHD were allocated to treatment and wait-list control groups. After the 12-wk intervention, the control group was crossed over to treatment.
