Recent observations suggest that the basic supranucleosomal structure of chromatin is a zigzag helical ribbon with a repeat unit made of two nucleosomes connected by a relaxed spacer DNA. A remarkable feature of one particular ribbon is that it solves the apparent paradox between the number of DNA turns per nucleosome and the total linking number of a(More)
Several methods have been used recently to determine gene expression profiles of cell populations. Here we demonstrate the strength of combining two approaches, serial analysis of gene expression (SAGE) and DNA arrays, to help elucidate pathways in breast cancer progression by finding genes consistently expressed at different levels in primary breast(More)
AIM The use of physical intervention on psychiatric inpatient units continues to be a source of debate and controversy. Some studies and national clinical guidelines have identified particular restraint positions as both dangerous and undesirable. The following study attempts to identify clinical variables that may make physical restraint in a particular(More)

This study investigates evolving methodologies for radar and merged gauge–radar quantitative precipitation estimation (QPE) to determine their influence on the flow predictions of a distributed hydrologic model. These methods include the National Mosaic and QPE algorithm package (NMQ), under development at the National Severe Storms Laboratory (NSSL), and(More)
We report a new measurement of the Cabibbo-Kobayashi-Maskawa parameter Vub made with a sample of 9.7 x 10(6) BB- events collected with the CLEO II detector. Using heavy quark theory, we combine the observed yield of leptons from semileptonic B decay in the end-point momentum interval 2.2-2.6 GeV/c with recent CLEO II data on B-->X(s)gamma to find Vub =(More)
In this paper, we discuss the possibility of using x-ray Compton scattering as a probe of the outer electronic structure of ions immersed in warm dense matter. It is proposed that the x-ray free-electron lasers currently under construction will provide an ideal tool for this, with the main pulse being used to create a uniform well-defined sample and the(More)
Three hundred and eighty-one women with operable breast cancer aged over 70 years were randomly allocated to 40 mg tamoxifen daily and optimal surgery or to tamoxifen alone. At a median follow-up of 34 months there was no demonstrable difference in survival rate or in quality of life between the two treatment groups. More patients treated with tamoxifen(More)
BACKGROUND Breast cancer has been considered a more indolent disease in the elderly, who are less tolerant of aggressive therapy. This trial tested the hypothesis that tamoxifen without surgery would provide adequate control of breast cancer for the remainder of life in elderly women, thereby sparing them surgery. METHOD Women aged over 70 years with(More)
Transcriptionally regulated growth-response genes play a pivotal role in the determination of the fate of a cell. p53 is known to transcriptionally regulate genes important in regulating cell growth potential. Using differential reverse transcription-PCR analysis of rat embryo fibroblast cells containing a temperature-sensitive p53 allele, we were able to(More)
Physical restraint of people experiencing mental health problems is a coercive and traumatic procedure which is only legally permitted if it is proportionate to the risk presented. This study sought to examine the decision-making processes used by mental health staff involved in a series of restraint episodes in an acute care setting. Thirty nurses were(More)
