ABSTRACT

BACKGROUND: Volunteers are expected to play a key role in children's hospice. However, there is a lack of information about how to cultivate effective volunteer training programs. OBJECTIVE: To verify the effect of a training program on volunteers' confidence in providing learning support and sharing experiences with children with life-threatening conditions and their families in a children's hospice. METHODS: In this pre-post study, participants were 48 undergraduate and graduate students from 3 universities in Japan. They received 5 lectures on children's hospice learning support. They evaluated the training program by rating their self-confidence in meeting each of the 15 program goals on a questionnaire. RESULTS: An exploratory factor analysis of the questionnaire yielded 12 goals in 4 factors: understanding of one's own and others' mental state, accommodating the learning needs of children with life-threatening conditions, understanding and accommodating the physical state of children with life-threatening conditions, and understanding the significance of children's hospice. A paired t test revealed that participants' self-confidence had increased significantly in 3 of these 4 factors after the program. However, the score for accommodating the learning needs of children with life-threatening conditions decreased but not significantly. CONCLUSION: Although it needs some improvements, the program was effective for improving volunteers' self-confidence in and understanding of learning support and sharing experiences with children with life-threatening conditions.

ABSTRACT

Follistatin is a functional antagonist of several members of the TGF-beta family of secreted signaling factors, including myostatin, the most powerful inhibitor of muscle growth characterized to date. Myostatin inhibition offers a novel therapeutic strategy for muscular dystrophy by restoring skeletal muscle mass and suppressing the progression of muscle degeneration. To assess the potential benefits of follistatin in treating muscle degenerative diseases, we examined the expression of myostatin and follistatin in Mdx mice, a model for Duchenne muscular dystrophy, and in B10 mice as a control. Our results demonstrated a temporary and coincident expression of follistatin and myostatin in both mouse strains, but this expression was significantly higher in Mdx mice than in B10 mice. The maximum expression of follistatin and myostatin in the presence of restoring necrotic muscle was detected 4 weeks after birth in Mdx mice. Interestingly, during the stage of complete regeneration, the absence of myostatin and follistatin proteins and a marked decrease in the expression of both genes were observed 9 weeks after birth in both mouse strains. These findings suggest that follistatin not only blocks myostatin but also allows other activators to function in muscle development, emphasizing that follistatin could be a very potent molecule in combating muscle loss during dystrophies and muscle ageing, disuse, or denervation.

ABSTRACT

The purpose of this study was to elucidate the relationship between large tubules and dentin caries by using human deciduous incisors that showed various levels of attrition but no macroscopical lesions resulting from caries. The teeth were cut longitudinally in the mesio-distal direction and the exposed surfaces observed with a high-resolution field emission scanning electron microscope. The inside of each large tubule showed dense collagen fibers running parallel to its long axis and small spherical bodies of aggregated crystals, but no marked attrition. In teeth where attrition had exposed dentin at the incisal edge, oral bacteria had infiltrated the large tubules. Furthermore, in teeth with advanced attrition, it was difficult to distinguish between the large tubules and the surrounding dentin matrix, and numerous bacteria were observed in both areas. These findings support the hypothesis that large tubules play a role in the pathway of caries formation in coronal dentin when incisal dentin is exposed by attrition. This suggests that early treatment of exposed dentin surfaces might be effective in preventing dental caries.
