OBJECTIVE To standardize outcome measures in systemic lupus erythematosus (SLE). Three indices were identified which could adequately describe outcome (disease activity, damage from disease, and health status); we describe here the development of the Disease Activity Index. METHODS Twenty-four variables were identified as important factors in a disease(More)
BACKGROUND Despite notable technical advances in therapy for malignant gliomas during the past decade, improved patient survival has not been clearly documented, suggesting that pretreatment prognostic factors influence outcome more than minor modifications in therapy. Age, performance status, and tumor histopathology have been identified as the(More)
In a prospective randomized trial designed to study the effectiveness of adjuvant chemotherapy following standard surgical treatment and radiation therapy, 233 eligible patients with medulloblastoma were treated by members of the Children's Cancer Study Group and the Radiation Therapy Oncology Group. Eligible patients were randomly assigned to receive(More)
Recently, the RTOG and ECOG concluded a joint randomized study on malignant gliomas that was in progress for the past five years. A total of 626 patients entered this protocol. Sixty-seven percent of the 535 evaluable patients have died and thus this represents a preliminary report of a major joint clinical trial. The objective of this study was to evaluate(More)
Alveolar soft part sarcoma is a rare, highly malignant tumor. It usually arises in the skeletal muscles in the extremities of patients in their second or third decade with a female preponderance of 2:1. Three additional cases, including the angiographic findings, have been presented. The literature pertaining to this subject also has been reviewed.
Most inbred strains of mice are susceptible to Leishmania amazonensis infection. We have examined the mechanism(s) underlying this generalized susceptibility using mice deficient in T cell development or in the expression of either MHC class I or class II. In contrast to wild-type C57BL/6 (B6) mice that uniformly developed large ulcerating lesions, mice(More)
The products of the yeast CDC73 and PAF1 genes were originally identified as RNA polymerase II-associated proteins. Paf1p is a nuclear protein important for cell growth and transcriptional regulation of a subset of yeast genes. In this study we demonstrate that the product of CDC73 is a nuclear protein that interacts directly with purified RNA polymerase II(More)
BACKGROUND Success of human oocyte cryopreservation depends on multiple cryobiological factors that could influence the developmental potential of the oocytes. The objective of this study was to examine the effects of different sucrose concentrations on the developmental potential of human frozen-thawed oocytes at different maturity stages. METHODS A(More)
