PURPOSE Primary lung tumors in children are rare. A wide range of histopathologic tumor types occurs. The incidence of these lesions and their outcomes are still largely unknown. This study aims to determine the incidence of different primary lung tumors in children and to contribute data leading to the development of evidence-based treatment models. (More)
BACKGROUND Components of the mitogen-activated protein kinase (MAPK) cascade have been implicated in apoptotic regulation. This study used gene expression profiling analysis to identify and implicate mitogen-activated protein kinase kinase (MEK5)-BMK1 (big mitogen-activated kinase-1)/extracellular signal related protein kinase (ERK5) pathway as a novel(More)
PURPOSE The purpose of this study was to evaluate recurrence and survival outcomes in pediatric adrenal cortical neoplasms. METHODS A 90-year retrospective review of children with adrenal cortical neoplasms was performed using multivariate Cox regression analysis to identify factors associated with recurrence and tumor-related mortality. RESULTS The(More)
Widespread use of MCF-7 human breast carcinoma cells as a model system for breast cancer has led to variations in these cells between different laboratories. Although several reports have addressed these differences in terms of proliferation and estrogenic response, variations in sensitivity to apoptosis have not yet been described. Tumor necrosis factor(More)
The mitogen-activated protein kinase (MAPK) cascade is a critical component in the regulation of cell survival and proliferation decisions. In breast carcinoma cells, activation of the p38-MAPK member of this family occurs in response to pro-inflammatory cytokines and cellular stress. The involvement of p38-MAPK in the activation of the transcription(More)
PURPOSE Low birth weight is the most important risk factor for developing necrotizing enterocolitis (NEC). We aimed to establish birth weight-based benchmarks for in-hospital mortality in neonates with NEC. METHODS Five hundred eleven centers belonging to the Vermont Oxford Network prospectively evaluated 71,808 neonates with birth weight of 501 to 1500 g(More)
The MCF-7 cell line was derived from a patient with metastatic breast cancer in 1970. Since then it has become a prominent model system for the study of estrogen receptor-positive breast cancer. With this model as a focus, this review summarizes important studies addressing tumor necrosis factor-alpha as a prototypical apoptosis-inducing cytokine in MCF-7(More)
Renal Medullary Carcinoma (RMC) is an aggressive malignancy that affects young black individuals with sickle cell trait. No effective treatment is available, resulting in an ominous clinical course, with overall survival averaging less than four months. We report rearrangement of the ALK receptor tyrosine kinase in a pediatric case of RMC harboring a(More)
BACKGROUND Nuclear factor-kappa B (NF-kappa B) is a known survival pathway, and it may explain differential sensitivity to tumor necrosis factor-alpha (TNF-alpha) and chemotherapeutic-induced apoptosis in apoptotically sensitive (APO+) and apoptotically resistant (APO-) Michigan Cancer Foundation-7 breast cancer cells. METHODS Crystal violet viability and(More)
OBJECTIVE The objective of our study was to compare the preoperative diagnostic accuracy of axial, multiplanar, and 3D MDCT images for evaluating congenital lung anomalies in pediatric patients and to assess the potential added diagnostic value of multiplanar and 3D MDCT images in this setting. MATERIALS AND METHODS We used our hospital information system(More)
