Short-acting β2-agonists (SABA) are widely used in the emergency department (ED) to treat patients with decompensated chronic obstructive pulmonary disease (COPD). We sought to model the effectiveness of nebulized SABA (terbutaline) on clinically relevant parameters associated with a reduction in work of breathing or respiratory muscle fatigue in decompensated COPD patients admitted to the ED.F...

During persistent infection, optimal expression of bacterial factors is required to match the ever-changing host environment. The gastric pathogen Helicobacter pylori has a large set of simple sequence repeats (SSR), which constitute contingency loci. Through a slipped strand mispairing mechanism, the SSRs generate heterogeneous populations that facilitate adaptation. Here, we present a model t...

Asthma often starts before six years of age. However, there remains uncertainty as to when and how a preschool-age child with symptoms suggestive of asthma can be diagnosed with this condition. This delays treatment and contributes to both short- and long-term morbidity. Members of the Canadian Thoracic Society Asthma Clinical Assembly partnered with the Canadian Paediatric Society to develop a...

Karnal bunt of wheat, caused by the fungus Tilletia indica, is an internationally regulated disease. Since its first detection in central Texas in 1997, regions in which the disease was detected have been under strict federal quarantine regulations resulting in significant economic losses. A study was conducted to determine the effect of weather factors on incidence of the disease since its fir...

BACKGROUND Traditional Asian and African medicine use immature okra fruits (Abelmoschus esculentus) as mucilaginous food to combat gastritis. Its effectiveness is due to polysaccharides that inhibit the adhesion of Helicobacter pylori to stomach tissue. The present study investigates the antiadhesive effect in mechanistic detail. METHODOLOGY A standardized aqueous fresh extract (Okra FE) from...

BACKGROUND Asthma management in Australia is suboptimal. The "Guidelines for provision of a Pharmacist Only medicine: short acting beta agonists" (SABA guidelines) and a novel West Australian "Asthma Action Plan card" (AAP card) were concurrently developed to improve asthma management. The aim of this qualitative research was to evaluate the collaborative, multidisciplinary and multifaceted imp...

A novel method to implement a sub-band adaptive beamforming array (SABA) is proposed. The lower and the higher sub-band signals are generated from the incoming full band signal and both the subband signals are optimised directly instead of decimation or down sampling. After optimisation the outputs of both the sub-bands are combined without interpolation or up sampling to generate the desired s...
