A conflict clause represents a backtracking solver’s analysis of why a conflict occurred. This analysis can be used to further prune the search space and to direct the search heuristic. The use of such clauses has been very important in improving the efficiency of satisfiability (SAT) solvers over the past few years, especially on structured problems coming(More)
In 1979 we initiated a phase III study in the Southwest Oncology Group (SWOG) which was designed to determine the value of chest radiation in limited-stage small-cell lung cancer patients achieving complete response after induction chemotherapy, and to test the use of wide-field v more limited-volume radiation in patients with partial responses (PRs) and(More)
A 55-year-old woman with a history of Stage IA endometrial adenocarcinoma, previously treated with surgery and intracavitary radiation therapy, had an isolated calcaneal metastasis. Normal radiographs led to a delay in the diagnosis of her relapse. An ankle computed tomographic scan finally identified a mass, and the surgical biopsy specimen confirmed the(More)
BACKGROUND Central nervous system primitive neuroectodermal tumours (CNS PNETs) are embryonal tumours occurring predominantly in children. Current lack of knowledge regarding their underlying biology hinders development of more effective treatments. We previously identified WNT/β-catenin pathway activation in one-third of CNS PNETs, which was potentially(More)
1. The objective of this study was to investigate whether it is possible to reduce phosphorus (P) excretion by feeding a lower level of dietary P than that currently recommended, without compromising welfare, and whether this is sensitive to the level of dietary calcium (Ca). 2. A randomised complete block design was used with a total of 224 1-d-old male(More)
Platinum-resistant ovarian cancer continues to be a difficult therapeutic problem. Clearly, molecularly targeted agents should be evaluated in this patient population. Patients were eligible for this phase II study with stage III or IV ovarian cancer, whose tumor expressed Kit (CD117) or platelet-derived growth factor receptor (PDGFR) and with relapse of(More)
Amonafide, a benzisoquinoline-1,3-dione was administered to 38 patients with recurrent or metastatic, bidimensionally measurable endometrial cancer. There were 34 patients with no prior cytotoxic chemotherapy, performance status of 0-2, and normal bone marrow, renal, and hepatic function were eligible for response and toxicity evaluation. Amonafide, 300(More)
This report describes 2 patients with longstanding seropositive rheumatoid arthritis (RA) treated with oral methotrexate (MTX) who developed large cell lymphoma of B cell phenotype. In situ hybridization studies showed nuclear staining for Epstein-Barr virus (EBV) within the malignant lymphoid cells. In both cases, the lymphoma was undetectable several(More)
A novel 2986-base transcript encoded by the antisense strand of the HRES-1 human endogenous retrovirus was isolated from peripheral blood lymphocytes. This transcript codes for a 218-amino acid protein, termed HRES-1/Rab4, based on homology to the Rab4 family of small GTPases. Antibody 13407 raised against recombinant HRES-1/Rab4 detected a native protein(More)
The term soft tissue sarcoma refers to a large variety of malignant tumors arising in extraskeletal connective tissues that connect, support, and surround discrete anatomic structures. All visceral organs also contain a connective stroma that can undergo malignant transformation. Because of the histological similarities of this group of tumors and their(More)
