In a prospective, longitudinal, population-based cohort study of familial and environmental influences on the development of wheezing respiratory illness in early childhood, we identified infant length, weight, gender, and exposure to maternal cigarette smoking as significant determinants of lung function during the first year of life. A cohort of 237(More)
In a prospective double-blind study of 535 medium-risk pregnancies, growth data obtained by ultrasonography and Doppler flow velocity waveform systolic to diastolic ratios were recorded at 18, 24, 28, and 34 weeks' gestation. A significant association was observed between uteroplacental systolic to diastolic ratios at 24 weeks' gestation and subsequent(More)
Unrelated bone marrow donor-recipient pairs were assessed retrospectively for matching of the HLA-B, -C region (beta-block) and HLA-DR, DQ region (delta block) of the major histocompatibility complex (MHC) using a new DNA-based method referred to as MHC-block typing. The method utilises non-HLA DNA polymorphisms in the MHC as markers of blocks of ancestral(More)
OBJECTIVE To conduct a cross-sectional, community-based, point prevalence study of inflammatory joint disease and other rheumatic disorders in 12-year-old children in a metropolitan community. METHODS After completion of a pilot study of 816 10-year-old children, a cross-sectional prevalence study was performed 2 years later on a randomized sample of 2241(More)
OBJECTIVE To test whether the introduction of Doppler waveform analysis into the ultrasound department of a tertiary level hospital reduces neonatal morbidity and improves obstetric management. DESIGN A randomized controlled trial. SETTING Department of Ultrasound, King Edward Memorial Hospital, Perth, Western Australia. SUBJECTS 505 women with(More)
The advances in computing and information storage have provided vast amounts of data. The challenge has been to extract knowledge from this raw data; this has lead to new methods and techniques such as data mining that can bridge the knowledge gap. This research aimed to assess these new data mining techniques and apply them to a soil science database to(More)
The ability of farmers to acquire knowledge to make decisions is limited by the information quality and applicability. Inconsistencies in information delivery and standards for the integration of information also limit decision making processes. This research uses a similar approach to the Knowledge Discovery in Databases (KDD) methodology to develop an ICT(More)
This paper examines the grains value chain in agriculture, and identifies the importance in developing strategies which could better secure food production. The study highlights examples of successful integration of ICTs in agricultural supply and value chains. The development of strategies to integrate these ICTs into the supply chain will be proposed. It(More)
Wheat grain proteins responses to mixing and thermal treatment were investigated using Mixolab-dough analysis systems with flour from two cultivars, Ventura-26 (normal amylose content) and Ventura-19 (reduced amylose content). Size exclusion high performance liquid chromatography (SE-HPLC) and two-dimensional gel electrophoresis (2-DGE) analysis revealed(More)
