Pink shrimp (P. brasiliensis and P. paulensis) residue: influence of extraction method on carotenoid concentration.

The main residue from the shrimp processing is formed by head and carapace and represents from 40 to 50% (w/w) of the integral shrimp. The recovery of the carotenoid fraction from this residue stands for an alternative to increase its aggregated value. Therefore, the objective of this study was to use the pink shrimp waste as raw material to obtain carotenoid enriched extracts, evaluating different pre-treatments and extraction methods.

Psychometric properties of the portuguese version of the Jebsen-Taylor test for adults with mild hemiparesis.

Objectives: to evaluate the psychometric properties of the Portuguese version of the Jebsen-Taylor Test (JTT) in patients with stroke.

Methods: forty participants who suffered a stroke in the cerebral hemisphere were videotaped while performing the JTT. Scores were defined by the time taken to perform the tasks, and two physical therapists evaluated the performance of the participants.

Effects of somatosensory stimulation on motor function after subacute stroke.

Background: Previous works showed potentially beneficial effects of a single session of peripheral nerve sensory stimulation (PSS) on motor function of a paretic hand in patients with subacute and chronic stroke.

Objective: To investigate the influence of the use of different stimulus intensities over multiple sessions (repetitive PSS [RPSS]) paired with motor training.

Methods: To address this question, 22 patients were randomized within the second month after a single hemispheric stroke in a parallel design to application of 2-hour RPSS at 1 of 2 stimulus intensities immediately preceding motor training, 3 times a week, for 1 month.

Effects of somatosensory stimulation on motor function in chronic cortico-subcortical strokes.

Somatosensory stimulation enhances aspects of motor function in patients with chronic, predominantly subcortical infarcts. We investigated the effects of somatosensory stimulation on motor function in stroke patients with predominantly cortical involvement in the middle cerebral artery territory in a double-blind, pseudorandomized crossover trial. Motor performance was evaluated with the Jebsen-Taylor test before, after 2-hour somatosensory stimulation, and after subsequent motor training (n=11).
