We report the results of a double-blind, placebo-controlled trial in nine cystic fibrosis (CF) subjects receiving cationic liposome complexed with a complementary DNA encoding the CF transmembrane conductance regulator (CFTR), and six CF subjects receiving only liposome to the nasal epithelium. No adverse clinical effects were seen and nasal biopsies showed(More)
It is now well known that the initial phase of graft-versus-host disease (GVHD) involves cytokine release during preconditioning of the recipient of an allogeneic bone marrow transplant (BMT). Tumor necrosis factor (TNF), in particular, has been implicated in pathological damage and is released pretransplant due to irradiation and cytotoxic preconditioning(More)
Respiratory samples from cystic fibrosis outpatients were cultured on Sabouraud's dextrose agar (SABD) containing antibiotics, Mycosel, and Scedosporium-selective medium (SceSel+). Thirty-two (14.7%) of 218 specimens from 11/69 (15.9%) patients yielded a Scedosporium sp., most frequently Scedosporium aurantiacum (17/218). Scedosporium was recovered on(More)
Aerosolized hypertonic saline is currently being investigated as a new agent for the treatment of impaired mucociliary clearance which occurs in many respiratory diseases. Mannitol aerosols, in particular dry powder inhalers, have been proposed as an alternative treatment to saline, offering the same osmotic load with other benefits. However, the effects of(More)
This paper shows how the concepts of lean manufacturing can be successfully transferred from the manufacture of cars and electrical goods to software development. The key lean concept is to minimize work in progress, so quickly forcing any production problems into the open. Production is then halted to allow each problem with the system producing the goods,(More)
STUDY OBJECTIVES To evaluate the ability of the Sonomat to diagnose obstructive sleep apnea (OSA). DESIGN Prospective and randomized. SETTING Sleep laboratory and home. PARTICIPANTS 62 subjects; 54 with a clinical history of OSA and 8 normal control subjects. INTERVENTIONS N/A. MEASUREMENTS AND RESULTS Simultaneous PSG and Sonomat recordings were(More)
The proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) is strongly implicated in graft-versus-host disease (GVHD) and other acute bone marrow transplant (BMT) complications. The antiinflammatory interleukin-10 (IL-10) antagonizes TNF-alpha and reduces GVHD. We previously showed association of recipient TNF (TNFd) and IL-10 (IL-10(-1064)) gene(More)
Human telomeres consist of arrays of the sequence TTAGGG up to 15-20 kb in length, which are essential for the maintenance of normal chromosomal stability. It has been suggested that genomic instability observed in tumours may be due to loss of telomere sequences. Somatic cells that are dividing continuously appear to progressively lose telomere sequences,(More)
It has been suggested that congenital bilateral absence of the vas deferens (CBAVD), an important cause of male infertility, is a variant of cystic fibrosis (CF). This study describes a defect in chloride conductance across the nasal epithelium of subjects with CBAVD which is dissimilar to that found in patients with CF. It also demonstrates normal sodium(More)
Proinflammatory cytokines including interferon-gamma (IFNgamma), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNFalpha) are implicated in the pathogenesis of acute graft-versus-host disease (aGVHD). Cytokine gene polymorphism is associated with functional differences in cytokine regulation and altered clinical performance in a variety of diseases.(More)
