Qualitative research: An overview of emerging approaches for data collection.

Objective: The aim of this study was to introduce new approaches to conduct qualitative research that may provide valuable insight into issues related to education, training and patient care in psychiatry.

Conclusions: A variety of data-collection tools is available for researchers and practitioners in psychiatry. These can be used independently or in conjunction with other quantitative and qualitative methods.

Regulatory features of interleukin-1beta-mediated prostaglandin E2 synthesis in airway smooth muscle.

Exposure of airway smooth muscle (ASM) cells to the cytokine IL-1beta results in an induction of PGE2 synthesis that affects numerous cell functions. Current dogma posits induction of COX-2 protein as the critical, obligatory event in cytokine-induced PGE2 production, although PGE2 induction can be inhibited without a concomitant inhibition of COX-2. To explore other putative regulatory features we examined the role of phospholipase A2 (PLA2) and PGE synthase (PGES) enzymes in IL-1beta-induced PGE2 production.
