Perceived Self-Efficacy Among Liver Transplant Candidates and Recipients

Self-efficacy is defined as one`s belief that one can perform the necessary behaviors to achieve one`s goals. This belief is one of the most powerful motivational predictors of how well a person will perform at almost any endeavor. Limited information is available, however, about self-efficacy in the organ transplantation population. This study aimed to identify the self-efficacy belief among liver transplant candidates and recipients and compare these results with demographic characteristics. The authors analyzed 100 patients who were candidates and recipients for liver transplantation in a Brazilian center. The average self-efficacy score for the candidates was significantly lower than for the recipients. Future investigation is necessary to explore possible interventions to be taken before and after liver transplantation that could influence self-efficacy of the organ transplantation patients.

Integration pattern of HIV-1 based lentiviral vector carrying recombinant coagulation factor VIII in Sk-Hep and 293T cells

293T and Sk-Hep-1 cells were transduced with a replication-defective self-inactivating HIV-1 derived vector carrying FVIII cDNA. The genomic DNA was sequenced to reveal LTR/human genome junctions and integration sites. One hundred and thirty-two sequences matched human sequences, with an identity of at least 98%. The integration sites in 293T-FVIIIDB and in Sk-Hep-FVIIIDB cells were preferentially located in gene regions. The integrations in both cell lines were distant from the CpG islands and from the transcription start sites. A comparison between the two cell lines showed that the lentiviral-transduced DNA had the same preferred regions in the two different cell lines.
