Development of a questionnaire to measure consumers' perceptions of service quality in community pharmacies.

Background: Recent changes within community pharmacy have seen a shift towards some pharmacies providing "value-added" services. However, providing high levels of service is resource intensive yet revenues from dispensing are declining. Of significance therefore, is how consumers perceive service quality (SQ).

The role of miR-18b in MDM2-p53 pathway signaling and melanoma progression.

Background: Although p53 is inactivated by point mutations in many tumors, melanomas infrequently harbor mutations in the p53 gene. Here we investigate the biological role of microRNA-18b (miR-18b) in melanoma by targeting the MDM2-p53 pathway.

Methods: Expression of miR-18b was examined in nevi (n = 48) and melanoma (n = 92) samples and in melanoma cell lines and normal melanocytes.
