BACKGROUND Preclinical studies indicate that the enzyme cyclooxygenase 2 plays an important role in ultraviolet-induced skin cancers. We evaluated the efficacy and safety of celecoxib, a cyclooxygenase 2 inhibitor, as a chemopreventive agent for actinic keratoses, the premalignant precursor of nonmelanoma skin cancers, and for nonmelanoma skin cancers,(More)
PURPOSE This study was conducted to evaluate the clinical significance of the localization of epidermal growth factor receptor (EGF-r), transforming growth factor (TGF)-alpha, and erbB-2 in the development, progression and prognosis of squamous cell cancers (SCCs) of the lung. EXPERIMENTAL DESIGN The localization of EGF-r, TGF-alpha, and erbB-2 was(More)
Sinonasal teratocarcinosarcoma is a highly malignant, polymorphous neoplasm that combines features of carcinosarcoma and teratoma. We describe the clinicopathologic features and management of a well-documented example of this unique entity that involved a 41-year-old Hispanic man. The patient presented with a history of multiple episodes of epistaxis, nasal(More)
BACKGROUND Local recurrence remains the major cause of death in patients with retroperitoneal sarcoma (RPS). There is no consensus regarding management of patients with recurrent RPS. STUDY DESIGN We performed a retrospective review of patients with recurrent RPS managed at 2 tertiary care centers between 1983 and 2008. Presentation, treatments, and(More)
The aim of this study was to examine the influence of different fat diets on serotonin receptor and transporter binding. Male Sprague-Dawley rats were fed a diet of either high saturated fat, omega-6 polyunsaturated fatty acid, omega-3 polyunsaturated fatty acid or low fat (control) for eight weeks. Using Beta-Imager quantification techniques,(More)
Sialidase (neuraminidase; acylneuraminyl hydrolase; EC erythrocytes obtained from different species are susceptible to rapid elimination from the circulation and are sequestered in the liver and spleen. The present studies were concerned with the mechanism of this clearance and how it may relate to the normal physiological process of(More)
The availability of human tissues to support biomedical research is critical to advance translational research focused on identifying and characterizing approaches to individualized (personalized) medical care. Providing such tissues relies on three acceptable models - a tissue banking model, a prospective collection model and a combination of these two(More)
Correlation of elevated levels of the lipogenic enzyme, fatty acid synthase (FASE), with advanced stages of some cancers has drawn attention to this enzyme as a possible marker of poor prognosis. Because recent studies have shown that cancer cells are dependent on fatty acid synthetic activity and pharmacologic inhibitors of this enzyme are selectively(More)
Myositis ossificans circumscriptus (MOC) or heterotopic ossification is a rare, benign soft tissue proliferation characterized by non-neoplastic heterotopic bone formation. It commonly occurs in young, adult male athletes, and is often, but not always, associated with trauma. Muscle and soft tissue, especially flexor muscles in the upper extremities and(More)
