1.  Restoration of MPTP-induced deficits by exercise and Milmed® co-treatment 
PeerJ  2014;2:e531.
1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induces permanent neurochemical and functional deficits. Following the administration of either two or four injections of the dopamine neurotoxin, MPTP, at a dose of 40 mg/kg, C57/BL6 mice were given access to running-wheels (30-min sessions, four times/week, Monday–Thursday) and treatment with the treated yeast, Milmed® (four times/week, Monday–Thursday), or simply running-wheel exercise by itself, over ten weeks. It was observed that the combination of physical exercise and Milmed® treatment, the MPTP + Exercise + Yeast (MC) group [MPTP + Exercise + Milmed® (MC)], restored spontaneous motor activity markedly by test day 10, restored completely subthreshold L-Dopa-induced activity, and dopamine concentration to 76% of control values, in the condition wherein two administrations of MPTP (2 × 40 mg/kg) were given prior to initiation of exercise and/or Milmed® treatment. Physical exercise by itself, MPTP + Exercise (MC) group, attenuated these deficits only partially. Administration of MPTP four times (i.e., 40 mg/kg, s.c., once weekly over four weeks for a total of 160 mg/kg, MPTP + Exercise + Yeast (MC) group [MPTP + Exercise + Milmed® (SC)] and MPTP + Exercise (SC), induced a lesioning effect that was far too severe for either exercise alone or the exercise + Milmed® combination to ameliorate. Nevertheless, these findings indicate a powerful effect of physical exercise reinforced by Milmed® treatment in restoring MPTP-induced deficits of motor function and dopamine neurochemistry in mice.

3.  Brief alcohol intervention in a psychiatric outpatient setting: a randomized controlled study 
Background
Although brief alcohol intervention (BI) is widely studied, studies from psychiatric outpatient settings are rare. The aim of this study was to investigate the effects of two variants of BI in psychiatric outpatients. By using clinical psychiatric staff to perform the interventions, we sought to collect information of the usefulness of BI in the clinical setting.
Methods
Psychiatric outpatients with Alcohol Use Disorders Identification Test (AUDIT) scores indicating hazardous or harmful drinking were invited to participate in the study. The outpatients were randomized to minimal (assessment, feedback, and an informational leaflet) or BI (personalized advice added). Measurements were performed at baseline and at six and 12 months after the intervention. The primary outcome was change in AUDIT score at the 12-month follow-up.
Results
In all, 150 patients were enrolled and received either a minimal intervention (n = 68) or BI (n = 82). At 12 months, there was a small reduction in AUDIT score in both groups, with no significant differences in outcome between groups. At 12-month follow-up, 21% of participants had improved from a hazardous AUDIT score level to a nonhazardous level, and 8% had improved from a harmful level to a hazardous level (8%).
Conclusions
Brief alcohol interventions may result in a reduction of AUDIT score to a small extent in psychiatric patients with hazardous or harmful alcohol use. Results suggest that BI may be of some value in the psychiatric outpatient setting. Still, more profound forms of alcohol interventions with risky-drinking psychiatric patients need elaboration.
