A solar-responsive zinc oxide photoanode for solar-photon-harvester photoelectrochemical (PEC) cells.

A highly efficient, nanostructured, solar-responsive zinc-oxide (SRZO) photoanode has been achieved by utilization of a versatile solution precursor plasma spray (SPPS) deposition technique. For the first time, it is demonstrated that a front-illumination type SRZO photo-anode fabricated with a ZnO/stainless steel (SS-304) configuration can generate an enhanced photo-electrochemical (PEC) current of 390 μA cm, under solar radiation from a solar simulator with an AM1.5 global filter (∼1 sun).

Diffusion-weighted versus volumetric imaging of the striatum in early symptomatic Huntington disease.

Measurement of striatal volume using magnetic resonance imaging (MRI) provides a marker of striatal degeneration in Huntington disease (HD). Recent evidence suggests that diffusion-weighted MRI (DWI) may also detect striatal damage in HD. Here, we compared the sensitivities of volumetric MRI and DWI at distinguishing 10 patients with early symptomatic HD from 12 age-matched controls.

Walking ability after implantation of a pallidal stimulator: analysis of plantar force distribution in patients with Parkinson's disease.

This preliminary study aimed to analyse the roll-off of the foot during gait before and after implantation of a unilateral pallidal electrode in severely affected patients with Parkinson's disease (PD). Five subjects were tested in a gait laboratory during the "on" phase of the medication cycle. Spatiotemporal variables demonstrated a pronounced increase of stride length and gait speed in three patients.

Turning in Parkinson's disease patients and controls: the effect of auditory cues.

Turning is an impaired activity in persons with Parkinson's disease (PwPD). The current study examines the turning characteristics in PwPD (9 freezers and 10 nonfreezers) and 9 controls, and explores the effect of rhythmic auditory cues while turning. Turning parameters were collected from a 180 degrees left U-turn during a noncued and a cued condition, using a 3D measuring system.

A 52-week open-label study of the long-term safety of ropinirole in patients with restless legs syndrome.

Objective: To assess the long-term safety and efficacy of ropinirole in the treatment of patients with restless legs syndrome (RLS) over 52 weeks.

Methods: A 52-week, multicentre, open-label continuation study involving 310 patients, conducted in 11 countries. Eligible patients from four parent studies were invited to participate.
