The Progression of Liver Fibrosis Is Related with Overexpression of the miR-199 and 200 Families
Chronic hepatitis C (CH) can develop into liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Liver fibrosis and HCC development are strongly correlated, but there is no effective treatment against fibrosis because the critical mechanism of progression of liver fibrosis is not fully understood. microRNAs (miRNAs) are now essential to the molecular mechanisms of several biological processes. In order to clarify how the aberrant expression of miRNAs participates in development of the liver fibrosis, we analyzed the liver fibrosis in mouse liver fibrosis model and human clinical samples
The shifting discourses of educational leadership:International trends and Scotlandâs response
Increasing emphasis has been placed on leadership within educational theory, policy and practice. Drawing on a wide range of academic literature and policy documents, this paper explores how the discourse of leadership has shifted and for what purposes. The authors are critical of the lack of conceptual underpinning for that discourse, evident both nationally and internationally, and they identify key issues that the teaching profession has been left to try to understand and make sense of. They caution that, despite attempts to align contemporary policy developments to position leadership as inherent in the role of every teacher, flaws in the conceptualisation of leadership, and particularly in favoured forms such as âdistributed leadershipâ and âteacher leadershipâ, pose significant challenges to a serious attempt to âreprofessionaliseâ teachers. Contemporary developments in Scottish education are referred to, exemplifying key tensions inherent in translating international trends into practice
