In these two separate projects, a total of 45 participants with PD were randomly assigned to either a Tai Chi group or a control group. The Tai Chi groups

in both projects completed a 16-week Tai Chi exercise session, GSK621 price while the control groups consisted of either a placebo (i.e., Qi-Gong) or non-exercise group. Tai Chi did not significantly improve Unified Parkinson’s Disease Rating Scale Part III score, selected gait initiation parameters or gait performance in either project. Combined results from both projects suggest that 16 weeks of class-based Tai Chi were ineffective in improving either gait initiation, gait performance, or reducing parkinsonian disability in this subset of persons with PD. Thus the use of short-term Tai Chi exercise should require further study before being considered a valuable therapeutic intervention for these domains in PD. (C) 2013 Elsevier Ltd.

“Objectives:

Assessment of the oral health-related quality of life and the modulating factors of patients demanding dental treatment in the city of Salamanca, through the use of two validated instruments: the OIDP-sp (Oral Impacts on Daily Performance) and OHIP-14 (Oral Health Impact Profile).

Study design: the study was conducted on a consecutive sample of 200 patients aged 18-65 years visiting an Integral Dental Centre in the city of Salamanca. Two validated instruments (OIDP-sp and ACP-196 chemical structure OHIP-14) were used to measure the oral health-related quality of life. An analogue visual scale was used to register oral satisfaction. Data on sociodemographic PHA-739358 chemical structure background, behavioural and clinical factors were also gathered. ANOVA, T Student Test, and both Pearson and Spearman correlations coefficients were used for the statistical analysis.

Results: according to the OIDP,

68.5% suffered from some kind of impact in their oral quality of life, while impact prevalence with the OHIP was 85%. Some other factors influencing the quality of life and degree of satisfaction were revealed.

Conclusions: patients over 45 years, regardless of their gender, from high social class, living in rural areas and with poor hygiene, showed higher impact and lower satisfaction. The study also revealed some clinical conditions closely related to the level of satisfaction.”
“The recent explosion of interest in epigenetics and chromatin biology has made a significant impact on our understanding of the pathophysiology of cerebral ischemia and led to the identification of new treatment strategies for stroke, such as those that employ histone deacetylase inhibitors. These are key advances; however, the rapid pace of discovery in chromatin biology and innovation in the development of chromatin-modifying agents implies there are emerging classes of drugs that may also have potential benefits in stroke.
