This report describes the development of small DNA microarrays of fully defined genes suitable for projects requiring detailed analysis of gene expression in sheep and/or cattle. Two arrays have been developed; the first is a small reference microarray (RIGRA) that has been used to validate experimental design and methodology; the second, a larger array(More)
BACKGROUND AND OBJECTIVES Encapsulating peritoneal sclerosis (EPS) is a severe peritoneal fibrotic reaction in patients on long-term peritoneal dialysis (PD). The early clinical features may be nonspecific. The purpose of the study is to assess the reliability and diagnostic utility of abdominal CT scanning in the diagnosis of EPS. DESIGN, SETTING,(More)
BACKGROUND Macrophage infiltration and cytokine production are important in the pathogenesis of crescentic glomerulonephritis in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis. The aim of this study was to investigate whether urinary levels of chemokines, monocyte chemoattractant protein-1 (MCP-1) and fractalkine, were useful tools for(More)
PROBLEM Bacteraemia in dialysis units accounts for major morbidity, mortality, and antibiotic usage. Risk is much greater when lines rather than fistulas are used for haemodialysis. Surveillance is critical for infection control, but no standardised surveillance scheme exists in the United Kingdom. DESIGN Prospective study in a London dialysis unit of the(More)
BACKGROUND AND PURPOSE An accurate prognosis is useful for patients, family, and service providers after acute stroke. METHODS We validated the Stroke subtype, Oxfordshire Community Stroke Project Classification, Age, and prestroke Rankin stroke score in predicting inpatient and 7-day mortality using data from 8 National Health Service hospital trusts in(More)
Substantial works have recently been reported on the mobility management in single-hop wireless networks (e.g. cellular networks and WLAN hotspots), while there has been an increased interest in multi-hop communications. This has made mobility management in heterogeneous multi-hop wireless networks (HMWNs) really interesting so that both single-hop and(More)
BACKGROUND Stroke is the third leading cause of death in developed countries and the leading cause of long-term disability worldwide. A series of national stroke audits in the UK highlighted the differences in stroke care between hospitals. The study aims to describe variation in outcomes following stroke and to identify the characteristics of services that(More)
One of the research challenges for 4G wireless systems is the design of mobility management techniques that integrate cellular and ad-hoc networks. Currently there are no structured mobility management schemes for these heterogeneous multi-hop networks. In this paper we propose an adaptive protocol for Mobility Management in Multi-Hop Heterogeneous Networks(More)
