BACKGROUND Excess adiposity has been shown to be associated with increased risk for breast cancer recurrence, and a plant-based eating pattern has been hypothesized to be protective. Whether a plant-based diet without specific energy goals will result in weight loss or changes in body composition in women who have been diagnosed with breast cancer has not(More)
Variograms are used to describe the spatial variability of environmental variables. In this study, the parameters that characterize the variogram are obtained from a variogram in a different but comparably polluted area. A procedure is presented for improving the variogram modelling when data become available from the area of interest. Interpolation is(More)
Thioredoxin-1 is a redox protein that, when overexpressed, causes increased cancer-cell growth and inhibited apoptosis. Thioredoxin-1 expression has been reported to be increased in several human primary tumors, but its relationship to tumor progression and patient survival has not been established. We studied the expression of thioredoxin-1 as measured(More)
PURPOSE Barrett's esophagus (BE) is a common premalignant lesion of the distal part of the esophagus that arises as a consequence of chronic duodenogastroesophageal reflux. Interleukin (IL)-6 is a pleiotropic cytokine that regulates immune defense mechanisms and hematopoiesis. In addition, IL-6 may also be involved in malignant transformation and tumor(More)
The distribution of alpha6/alpha3 integrin in adhesion complexes at the basal membrane in human normal and cancer prostate glands was analyzed in 135 biopsies from 61 patients. The levels of the polarized alpha6/alpha3 integrin expression at the basal membrane of prostate tumor glands were determined by quantitative immunohistochemistry. The alpha6/alpha3(More)
OBJECTIVE Gastroesophageal reflux disease (GERD) plays a major role in the development of Barrett's esophagus. Recently, we demonstrated that duration of esophageal acid exposure in the distal esophagus correlates with the length of Barrett's mucosa. The aim of this study was to determine whether there is a relationship between the rate of the change in(More)
OBJECTIVE Clopidogrel decreases recurrent ischemic events and improves intracoronary stent patency. There are scarce data on the effect of short-term and long-term clopidogrel on symptom recurrence and adverse cardiac events following off-pump coronary artery bypass graft surgery (OPCAB). METHODS Postoperative antiplatelet medication use was prospectively(More)
PURPOSE This phase II trial evaluated bevacizumab plus erlotinib in platinum-resistant ovarian cancer; exploratory biomarker analyses, including that of tumor vascular endothelial growth factor A (VEGF-A), were also done. EXPERIMENTAL DESIGN Forty heavily pretreated patients received erlotinib (150 mg/d orally) and bevacizumab (10 mg/kg i.v.) every 2(More)
The 14-3-3 proteins are a set of seven highly conserved proteins that have recently been implicated in having a role in human tumorigenesis. However, the mechanism by which 14-3-3 proteins may act in this capacity is not well understood. In this study, we examined the expression of one of the 14-3-3 family members, 14-3-3σ, since it was shown previously to(More)
Arginine is catabolized by NOS2 and other nitric oxide synthases to form nitric oxide. We evaluated the roles of dietary arginine and Nos2 in Apc-dependent intestinal tumorigenesis in Min mice with and without a functional Nos2 gene. NOS2 protein was expressed only in intestinal tissues of Apc(Min/+) Nos2+/+ mice. NOS3 expression was higher in intestinal(More)
