Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective. 相似文献

The study compared teachers’ and parents’ views about elementary school children’s psychosocial adjustment with and without a history of early grade retention. The sample included retained and non-retained students currently in Grades Two and Four (age range 7.5 to 11.6 years) in Cypriot public schools. The retained students experienced early grade retention either in kindergarten or Grade One and, therefore, were one year older than their current classmates. Both parents and teachers of all children completed a psychosocial adjustment inventory designed to assess social, emotional, and school competence as well as behaviour problems. The findings indicated important differences between teachers and parents in their evaluation of children’s psychosocial adjustment, but notable similarities in consistently evaluating early-retained children lower on all aspects of adjustment. Teachers evaluated all students lower than parents in terms of behaviour, school, and social competence. Both groups, however, considered retained students lower in social and school competence regardless of grade level. The implications of these findings in relation to evaluation aspects of psychosocial adjustment and the practice of early-grade retention are discussed. 相似文献

Ability-grouping has been studied extensively in relation to children's academic, but not emotional and behavioral outcomes. The sample comprised 7259 U.K. children (50% male) with data on between-class and within-class ability-grouping at age 7. Peer, emotional, hyperactivity, and conduct problems were measured at ages 7, 11, and 14 years. Children in low within-class ability groups showed more hyperactivity and emotional problems across the study period compared to non-grouped children, after adjustments for the different types of ability grouping and confounding. Additionally, children in the middle within-class ability groups showed more, and those in the top within-class groups less, hyperactivity compared to non-grouped children, after adjustment. Children in lower within-class groups should be monitored closely to ensure that their well-being is not compromised. 相似文献
