OBJECTIVE To examine the presence and extent of apoptosis as well as the affected cell types in human lung tissue before, during, and after transplantation. SUMMARY BACKGROUND DATA Apoptosis has been described in various human and animal models of ischemia-reperfusion injury, including heart, liver, and kidney, but not in lungs. Therefore, the presence of(More)
Ischemia-reperfusion (IR) injury is a major cause of organ dysfunction following lung transplantation. We have recently described increased apoptosis in transplanted human lungs after graft reperfusion. However, a direct correlation between ischemic time, cell death, and posttransplant lung function has not yet been demonstrated. We hypothesized that an(More)
BACKGROUND Gene therapy's potential to modify donor organs to better withstand the process of transplantation has yet to be realized. To determine whether gene transfection is feasible to treat the early post-transplant injury of ischemia-reperfusion, we compared transfection of lungs in the donor prior to organ procurement with transfection of harvested ex(More)
BACKGROUND It is a common perception that preoperative radiation increases the incidence of urologic complications following composite resection, but there is little evidence to support or refute this claim. METHODS Patients who underwent ureteric reconstruction as a component of en bloc resection for locally advanced or recurrent colorectal cancer were(More)
We examined the effect of adenovirus-mediated transtracheal transfer of the human interleukin 10 (hIL-10) gene on lung ischemia-reperfusion (IR) injury, which is the insult due to hypothermic preservation plus graft reperfusion, and posttransplant lung function in Lewis rat lungs. Thirty rats were divided into 6 groups (n = 5). Groups 1 and 4 received 5 x(More)
BACKGROUND We have previously shown that cell death is a pathophysiologic consequence of ischemia-reperfusion and that interleukin-10 gene therapy improves the function of transplanted lungs. Interleukin-10 downregulates the inflammatory response and can inhibit apoptosis. The objective was to determine whether donor lung transfection with the(More)
RATIONALE Meta-analyses demonstrate that surveillance following curative-intent colorectal cancer (CRC) surgery can improve survival. Our multidisciplinary team adopted a stringent CRC follow-up (FU) guideline in 2000. The purpose of this study was to assess adherence and barriers to FU for CRC. METHODS Patients with primary CRC aged 19-75 years, treated(More)
BACKGROUND The effects of the ischemia-reperfusion process of organ transplantation on nitric oxide (NO) synthase (NOS) in humans are unknown. The effects of NO inhalation on endogenous NOS expression and activity are controversial. The authors hypothesized that NO inhalation may affect ischemia-reperfusion-induced alterations of the endogenous NOS system.(More)
Many cell culture models have been developed to study ischemia-reperfusion injury; however, none is specific to the conditions of lung preservation and transplantation. The objective of this study was to design a cell culture model that mimics clinical lung transplantation, in which preservation is aerobic and hypothermic. A549 cells, a human pulmonary(More)
