Summary:

In this study, we investigated a novel approach for HCC treatment by inducing overexpression of GRK2 in human HCC cells. We found that overexpression of GRK2 through recombinant adenovirus transduction inhibits the growth of human HCC cells. BrdU incorporation assay showed that the growth inhibition caused by elevated GRK2 level was due tot he reduced cell proliferation but not apoptosis. To examine the anti-proliferative function of increased GRK2 level, we performed cell cycle analysis using propidium iodide staining. We found that the proliferation suppression was associated with G2/M phase cell cycle arrest by the wild type GRK2 but not …

Conclusions:

Use of liver grafts from older donors presents similar survival outcomes as grafts from younger donor age. Therefore, it offers a viable option to expand the donor pool and increase number of OLTs.

However, there is higher incidence of retransplantation due to primary graft non-function, and longer hospital length of stay observed in the older donor age group.

Further studies using larger patient populations are needed to validate our results.

BACKGROUND: The purpose of this study was to evaluate the use of simulated patients in conjunction with anatomic and tissue task-training models to assess skills.

METHODS: Faculty reviewed the objectives of the clerkship to identify skills to be acquired. Three cases were developed related to rectal examination, suturing, and inserting intravenous lines and nasogastric tubes. Student scores were based on their ability to gather data from simulated patients and perform procedures on simulation models.

RESULTS: A total of 670 students were assessed between 2006 and 2009. Alpha reliability coefficients were .97 for Communication/Interpersonal Skills, .71 for Procedures, and .58 for …
