Vaccination with naked DNA elicits cellular and humoral immune responses that have a T helper cell type 1 bias. However, plasmid vectors expressing large amounts of gene product do not necessarily induce immune responses to the encoded antigens. Instead, the immunogenicity of plasmid DNA (pDNA) requires short immunostimulatory DNA sequences (ISS) that(More)
This paper describes a subsystem for the Windows NT 4.0 Operating System which implements a kernel-mode execution environment for Win32 compatible tasks and threads that have hard real-time performance characteristics (deterministic interrupt response and dispatch la-tencies). This subsystem is a proper OS extension which requires no modifications to the(More)
BACKGROUND Acupuncture is increasingly being used for many conditions including chronic neck pain. However the evidence remains inconclusive, indicating the need for further well-designed research. The aim of this study was to conduct a pilot randomised controlled parallel arm trial, to establish key features required for the design and implementation of a(More)
Natural products chemistry is the discipline that lies at the heart of modern pharmacognosy. The field encompasses qualitative and quantitative analytical tools that range from spectroscopy and spectrometry to chromatography. Among other things, modern research on crude botanicals is engaged in the discovery of the phytochemical constituents necessary for(More)
BACKGROUND Uridine is a therapy for hereditary orotic aciduria and is being investigated in other disorders caused by mitochondrial dysfunction, including toxicities resulting from treatment with nucleoside reverse transcriptase inhibitors in HIV. Historically, the use of uridine as a therapeutic agent has been limited by poor bioavailability. A food(More)
Platelet endothelial cell adhesion molecule (PECAM or CD31) is a cell adhesion molecule expressed on circulating leukocytes and endothelial cells that plays an important role in mediating neutrophil and monocyte transendothelial migration in vivo. In this study, we investigated whether eosinophils, like neutrophils and monocytes, utilize PECAM for tissue(More)
We have investigated the importance of cell-surface serine- and/or threonine-linked oligosaccharide adhesion molecules synthesized by the Golgi enzyme core 2 beta-1,6-N-acetylglucosaminyltransferase (C2GlcNAcT) in mediating eosinophil trafficking to the lung in studies utilizing C2GlcNAcT-I-deficient mice. The number of bronchoalveolar eosinophils, the(More)
