PURPOSE Most patients with advanced pancreas cancer experience pain and must limit their daily activities because of tumor-related symptoms. To date, no treatment has had a significant impact on the disease. In early studies with gemcitabine, patients with pancreas cancer experienced an improvement in disease-related symptoms. Based on those findings, a(More)
A simple and efficient method for synthesizing pure single stranded RNAs of virtually any structure is described. This in vitro transcription system is based on the unusually specific RNA synthesis by bacteriophage SP6 RNA polymerase which initiates transcription exclusively at an SP6 promoter. We have constructed convenient cloning vectors that contain an(More)
This review represents an update of the nomenclature system for the UDP glucuronosyltransferase gene superfamily, which is based on divergent evolution. Since the previous review in 1991, sequences of many related UDP glycosyltransferases from lower organisms have appeared in the database, which expand our database considerably. At latest count, in animals,(More)
In this paper, we report that when the low-level features of targets and distractors are held constant, visual search performance can be strongly influenced by familiarity. In the first condition, a [symbol: see text] was the target amid [symbol: see text]s as distractors, and vice versa. The response time increased steeply as a function of number of(More)
BACKGROUND AND METHODS MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) has been the standard treatment for Hodgkin's disease for almost 20 years. In a randomized, multicenter trial, we compared three regimens of primary systemic therapy for newly diagnosed advanced Hodgkin's disease in Stages IIIA2, IIIB, and IVA or IVB: (1) MOPP alone(More)
In higher eukaryotes, the polypyrimidine-tract (Py-tract) adjacent to the 3' splice site is recognized by several proteins, including the essential splicing factor U2AF65, the splicing regulator Sex-lethal (Sxl), and polypyrimidine tract-binding protein (PTB), whose function is unknown. Iterative in vitro genetic selection was used to show that these(More)
PURPOSE To examine the individual and joint effect of various pretreatment clinical characteristics on the survival of patients with mesothelioma treated by the Cancer and Leukemia Group B (CALGB). PATIENTS AND METHODS Between June 1984 and September 1994, 337 patients with malignant mesothelioma and no prior chemotherapy were accrued to seven phase II(More)
BACKGROUND Results from phase II studies in patients with stage IIIA non-small-cell lung cancer with ipsilateral mediastinal nodal metastases (N2) have shown the feasibility of resection after concurrent chemotherapy and radiotherapy with promising rates of survival. We therefore did this phase III trial to compare concurrent chemotherapy and radiotherapy(More)
PURPOSE To evaluate the technical feasibility and safety of video-assisted thoracic surgery (VATS) lobectomy for small lung cancers. PATIENTS AND METHODS The Cancer and Leukemia Group B 39802 trial was a prospective, multi-institutional study designed to elucidate the technical feasibility of VATS in early non-small-cell lung cancer (NSCLC) using a(More)
Pre-mRNA splicing complex assembly is mediated by two specific pre-mRNA-snRNP interactions: U1 snRNP binds to the 5' splice site and U2 snRNP binds to the branch point. Here we show that unlike a purified U1 snRNP, which can bind to a 5' splice site, a partially purified U2 snRNP cannot interact with its target pre-mRNA sequence. We identify a previously(More)
