Obliterative airway disease (OAD) is the major complication after lung transplantations that limits long term survival (1-7). To study the pathophysiology, treatment and prevention of OAD, different animal models of tracheal transplantation in rodents have been developed (1-7). Here, we use two established models of trachea transplantation, the heterotopic and orthotopic model and demonstrate t...
Acute aortic dissection is one of the rare aortic complications that occur after orthotopic heart transplantation. We report the second case of successful surgical treatment of aortic dissection confined to the donor aorta in a recipient of an orthotopic cardiac allograft. A 68-year-old patient was admitted with chest pain and shortness of breath 7 years after orthotopic heart transplantation. ...
Long considered oncologically hazardous or functionally damaging, radical cystectomy with orthotopic urinary diversion is the accepted standard of care for invasive bladder cancer. A number of anatomical and clinical observations have come together to make orthotopic urinary diversion possible for female patients. Not only have these observations led to the development of an oncologically safe,...
BACKGROUND Wilms tumor (WT) is a pediatric tumor of the kidney, the treatment of which includes heavy chemotherapy. Affected children would likely benefit from more targeted therapies with limited side effects. Establishment of relevant orthotopic WT xenografts is important to better understand mechanisms of WT growth and for preclinical drug testing. PROCEDURE Here we established and charact...
Advanced tumors produce an excessive amount of transforming growth factor β (TGFβ), which promotes tumor progression at late stages of malignancy. The purpose of this study was to develop anti-TGFβ therapeutics for cancer. We synthesized a novel small-molecule TGFβ receptor I kinase (activin receptor-like kinase 5) inhibitor termed N-[[4-([1,2,4]triazolo[1,5-a]pyridin-6-yl)-5-(6-methylpyridin-2...
Objective. Although a large debate exists regarding the need for reflux prevention in ileal orthotopic neobladders, it is our policy to continue performing nonrefluxing ureteroileal anastomoses for our patients. An ideal uretero-ileal anastomosis must be simple, nonrefluxing, as well as non-obstructive. Here, we present a new antireflux mechanism for orthotopic ileal neobladders. Methods. 12 ra...
We describe the development of an aggressive orthotopic metastatic model of esophageal cancer, which is visualized in real time with combined magnetic resonance imaging (MRI) and fluorescence imaging. The aim of the study was to describe the development of a novel model of metastatic tumor disease of esophageal carcinoma and use this model to evaluate fluorescence and MRI in early detection of ...
OBJECTIVES The purpose of the present study was to develop and validate noninvasive bioluminescence imaging methods for differentially monitoring primary and abdominal metastatic tumor growth in mouse orthotopic models of pancreatic cancer. METHODS A semiautomated maximum entropy segmentation method was implemented for the primary tumor region of interest, and a rule-based method for manually...
PURPOSE Brain tumor xenografts initiated from human glioblastoma (GBM) stem-like cells (TSC) simulate the biological characteristics of GBMs in situ. Therefore, to determine whether the brain microenvironment affects the intrinsic radiosensitivity of GBM cells, we compared the radioresponse of GBM TSCs grown in vitro and as brain tumor xenografts. EXPERIMENTAL DESIGN As indicators of DNA doub...
