ÐTask scheduling is essential for the proper functioning of parallel processor systems. Scheduling of tasks onto networks of parallel processors is an interesting problem that is well-defined and documented in the literature. However, most of the available techniques are based on heuristics that solve certain instances of the scheduling problem very(More)
The discovery of Australopithecus anamensis fossils from strata lying between tephra dated at 4.17 and 4.12 million years ago, and from slightly higher strata not well constrained in age by overlying dated units, provoked the claim that more than one species might be represented: it was suggested that the stratigraphically higher fossils, which include the(More)
During beneficial inflammation, potentially tissue-damaging granulocytes undergo apoptosis before being cleared by phagocytes in a non-phlogistic manner. Here we show that the rate of constitutive apoptosis in human neutrophils and eosinophils is greatly accelerated in both a rapid and concentration-dependent manner by the fungal metabolite gliotoxin, but(More)
PURPOSE The aim of this study was to examine the effect of 0.3 g x kg(-1) of NaHCO3, 0.21 g x kg(-1) of NaCl, and a low-calorie placebo control (PC) on high-intensity arm ergometry in eight college wrestlers (aged 20.6 +/- 0.8 yr, body mass 70.4 +/- 2.1 kg). METHODS Subjects performed eight 15-s intervals of maximal effort arm ergometry separated by 20 s(More)
BACKGROUND The reticular basement membrane (Rbm) in smokers and especially smokers with COPD is fragmented with "clefts" containing cells staining for the collagenase matrix-metalloproteinase-9 (MMP-9) and fibroblast protein, S100A4. These cells are also present in the basal epithelium. Such changes are likely hallmarks of epithelial mesenchymal transition(More)
Niemann-Pick disease type C is a clinically heterogeneous storage disorder with an unknown primary metabolic defect. We have undertaken somatic cell hybridisation experiments using skin fibroblast strains from 12 patients representing a wide clinical spectrum. Preliminary experiments using filipin staining of free cholesterol as a marker for complementation(More)
To describe the use of recombinant activated factor VII (rFVIIa) in patients with life-threatening haemorrhage. We report a case series of Australian patients with life-threatening haemorrhage who were treated with rFVIIa prior to August 2002 namely 21 patients, median age 45 years (range 22-79 years), 33% (seven of 21) female. The major causes for bleeding(More)
UNLABELLED We describe our institutional efficacy experience of azithromycin 250 mg thrice weekly in adult non-cystic fibrosis bronchiectasis. METHODS Eligibility criteria for prophylactic azithromycin included 3 exacerbations requiring rescue antibiotics over the previous 6 months. The clinical records of 56 bronchiectasis patients on azithromycin were(More)
BACKGROUND AND OBJECTIVE In COPD, the airways are chronically inflamed, and we have now observed fragmentation of the reticular basement membrane (Rbm). This appears to be a hallmark of the process known as epithelial mesenchymal transition (EMT), in which epithelial cells migrate through the Rbm and differentiate into fibroblasts. The aim of this study was(More)
BACKGROUND There are few data in asthma relating airway physiology, inflammation and remodelling and the relative effects of inhaled corticosteroid (ICS) treatment on these parameters. A study of the relationships between spirometric indices, airway inflammation, airway remodelling, and bronchial hyperreactivity (BHR) before and after treatment with high(More)
