Impacts of early clinical exposure on undergraduate student professionalism-a qualitative study.

Introduction: Early clinical exposure (ECE), or authentic human contact in a social or clinical context during preclinical training, has been adopted by many medical schools. This study aims to investigate how medical students' sense of professionalism changed after ECE intervention, with the aim of informing curriculum design to enhance student awareness of the importance of medical professionalism.

Method: Focus groups of ECE students were held to collect data for the study.

Lin-28B expression promotes transformation and invasion in human hepatocellular carcinoma.

MicroRNAs (miRNAs) play critical roles in embryonic development and are frequently deregulated in human cancers. The let-7 family members are tumor-suppressing miRNAs and are frequently downregulated in cancer cells. Lin-28 and Lin-28B are RNA-binding proteins highly expressed in embryonic tissues.
