The onset of labor alters corticotropin-releasing hormone type 1 receptor variant expression in human myometrium : putative role of interleukin-1ß
CRH targets the human myometrium during pregnancy. The efficiency of CRH actions is determined by expression of functional receptors (CRH-R), which are dynamically regulated. Studies in myometrial tissue biopsies using quantitative RT-PCR demonstrated that the onset of labor, term or preterm, is associated with a significant 2- to 3-fold increase in CRH-R1 mRNA levels. Detailed analysis of myometrial CRH-R1 mRNA variants showed a decline of the pro-CRH-R1 mRNA encoding the CRH-R1ß variant during labor and increased mRNA levels of CRH-R1d mRNA. Studies in myometrial cells identified IL-1ß as an important regulator of myometrial CRH-R1 gene expression because prolonged treatment of myometrial cells with IL-1ß (1 ng/ml) for 18 h induced expression of CRH-R1 mRNA levels by 1.5- to 2-fold but significantly attenuated CRH-R1ß mRNA expression by 70%. In contrast, IL-1ß had no effect on CRH-R1d mRNA expression. Studies using specific inhibitors suggest that ERK1/2, p38 MAPK, and downstream nuclear translocation of nuclear factor-B mediate IL-1ß effects on myometrial CRH-R1 gene. However, the increased CRH-R1 mRNA expression was associated with a dampening of the receptor efficacy to activate the adenylyl cyclase/cAMP signaling cascade. Thus, our findings suggest that IL-1ß is an important regulator of CRH-R1 expression and functional activity, and this interaction might play a role in the transition of the uterus from quiescence to active contractions necessary for the onset of parturition
Pre-service teachers\u27 use of ICT to collaborate to complete assessment tasks
This research explored the use of ICT products by n = 123 pre-service teachers to complete collaborative assessments. Students responded to a questionnaire relating to the use, benefits and limitations, and what would better enable the use of ICT for collaborative assessment purposes. The ICT products favoured by students did not support some key elements necessary for online collaboration, through either student use or product functionality. Poor Internet access was a commonly cited limitation with the effect of reducing access to available ICT skills training. Suggestions for changes to course structure and content and further research are made
Inquiry-Based Learning (IBL) as a Driver of Curriculum: A Staged Approach
Inquiry-based learning provides students with an opportunity to take ownership of their learning while developing important higher order skills necessary for designing innovative solutions to complex modern health problems. In our undergraduate health sciences program, critical thinking, creativity, research skills and innovative thinking are core program learning outcomes, and thus inquiry-based learning is an important pillar of our curriculum. We have taken a staged approach, integrating inquiry-based learning (IBL) into each year of a four-year undergraduate degree program that scaffolds structure and independence to suit undergraduate student needs from the first to third years and culminating in an independent, student-driven honours thesis in the fourth year. In this paper, we share practical IBL strategies that pair with student needs throughout the four-year continuum and highlight strategies to address challenges at each stage of learning

Getting to know you: Engagement and relationship building: First interim national positive futures case study research report
This report represents the culmination of the first phase of the Positive Futures (PF) Case Studies Research Project rather than a definitive set of findings as such. Rather like the PF programme itself it is very much a work in progress which is evolving all the time in the context of the action research approach we have adopted. This approach involves a cycle of action and reflection, with both the projects and research adapting in relation to the themes that emerge from the study as it progresses. Nevertheless whilst this element of the research has been concerned as much with the establishment of relations with projects and participants as investigating the relationships between them, we have begun to identify a number of tentative themes and findings. These themes are presented in a fashion which is intended to guide the future direction of projects every bit as much as to gain abstract theoretical insight. Yet this recognition of the importance of practicality and direction should not distract from the importance of gaining a wider contextual feel for the programme. For whilst this summary is intended to highlight the key themes emerging from the research and the policy and practice issues associated with them, it is in the detail of the main report that a full appreciation of the PF approach emerges. It is from the more narrative accounts in these subsequent parts that we have drawn the conclusions and recommendations presented here and which will provide the baselines against which we assess future progress. Indeed these accounts are themselves drawn from three regional reports focused on the seven case studies that constitute the overall national research project
