ABSTRACT

Complex hand dexterity is fundamental to our interactions with the physical, social, and cultural environment. Dexterity can be an expression of creativity and precision in a range of activities, including musical performance. Little is understood about complex hand dexterity or how virtuoso expertise is acquired, due to the versatility of movement combinations available to complete any given task. This has historically limited progress of the field because of difficulties in measuring movements of the hand. Recent developments in methods of motion capture and analysis mean it is now possible to explore the intricate movements of the hand and fingers. These methods allow us insights into the neurophysiological mechanisms underpinning complex hand dexterity and motor learning. They also allow investigation into the key factors that contribute to injury, recovery and functional compensation. The application of such analytical techniques within musical performance provides a multidisciplinary framework for purposeful investigation into the process of learning and skill acquisition in instrumental performance. These highly skilled manual and cognitive tasks present the ultimate achievement in complex hand dexterity. This paper will review methods of assessing instrumental performance in music, focusing specifically on biomechanical measurement and the associated technical challenges faced when measuring highly dexterous activities.

ABSTRACT

BACKGROUND: Massage as a complementary and alternative therapy has been associated with enhancing health and coping with treatment-related side effects in patients with breast cancer worldwide. This systematic review examined whether massage interventions provide any measurable benefit in breast cancer-related symptoms. METHODS: Randomized controlled trials (RCTs) were searched for in PubMed, EMBASE.com and the Cochrane Library through June 2013. We evaluated the quality of the studies included by the Cochrane Handbook 5.2 standards and analyzed the data using the Cochrane Collaboration's RevMan 5.2 software. RESULTS: Eighteen RCTs with a total of 950 participants were included. Compared with the control group, our meta-analysis showed that patients receiving regular use of massage had significantly greater reductions in anger and fatigue symptoms. However, there were no significant differences in depression, anxiety, pain, upper limb lymphedema, cortisol and health-related quality of life. CONCLUSIONS: The current evidence demonstrates that there was mild evidence that massage may be a useful intervention in alleviating negative emotions and fatigue in patients with breast cancer. More trials with longer follow-up are needed to determine the exact long-term efficacy of this class of complementary and alternative medicine on breast cancer-related symptoms and quality of life.

ABSTRACT

Ex vivo expansion of endothelial progenitor cells (EPCs) may be a promising strategy to overcome the clinical problem of limited cell numbers. As the culture medium is the key for the cell characteristics, the effects of different culture media on EPCs were investigated in the present study. Rat bone marrow mononuclear cells were cultured in different media, including M-199 media with 20% fetal bovine serum (FBS) and bovine pituitary extract (M1); M-199 media with 10% FBS, 20 ng/ml vascular endothelial growth factor (VEGF) and 10 ng/ml basic fibroblast growth factor (bFGF; M2) or epidermal growth medium (EGM)-2MV media. The cell morphology and biological functions, such as proliferation, adhesion, migration, tube formation and nitric oxide (NO) production were subsequently assayed in vitro. Moreover, endothelial biomarkers and apoptosis were also analyzed. The results showed that endothelial­like cells appeared in all of the culture systems. First­passage cells, namely early EPCs, tended to form colonies in M2 and EGM-2MV media but showed a fusiform shape in M1 media. The 3rd or 4th generation EPCs, namely late EPCs, cultured in EGM-2MV media exhibited increased adhesion, migration, tube formation and NO production as compared with EPCs in M1 or M2 media. Furthermore, late EPCs cultured in EGM-2MV expressed higher levels of endothelial cell markers, such as von Willibrand factor (vWF)and CD31, but relatively greater levels of apoptosis were observed. In conclusion, cell culture conditions, for example the medium used, affects the biological properties of bone marrow-derived early and late EPCs.
