BACKGROUND AND PURPOSE Thrombolysis for acute ischemic stroke saves societal costs, but hospitals that practice acute stroke care appear to shoulder the burden of the cost, which exceeds reimbursement. With creation of the diagnosis-related group (DRG) 559, the US Centers for Medicare and Medicaid Services pays hospitals approximately US $6000 more per case when thrombolysis is administered. We...

A procedure permitting the isolation of large amounts of cytochrome b-559 from chloroplasts of barley is described. The isolated cytochrome b-559 has an apparent molecular weight of 120,000. The protein equivalent weight per mole of heme is 30,000. Depending on the electrophoretic conditions used, this molecule can be dissociated into components with apparent molecular weights of 31,000, 30,000...

Diversity and distribution of exotic plant taxa in Kosciuszko National Park in south-eastern Australia were reviewed based on 1103 records of exotics from 18 vegetation surveys conducted between 1986 and 2004. 154 taxa from 23 families were recorded in the alpine to montane zones, with eleven taxa in the alpine, 128 taxa in the subalpine and 69 taxa in the montane zone. Nearly all taxa were ass...

Photosystem II (PSII) is the site of action of a large number of commercial herbicides and it is the site, where photoinhibition appears when plants are exposed to high light intensities. It is known that manganese, calcium and chloride ions are essential for optimal electron flow within PSII. Recently we have found that at very low concentrations (1-1.5 Cu 2+ / reaction center) copper improves...

PURPOSE To review records of children referred to our hospital for developmental dysplasia of the hip (DDH) and evaluate the effectiveness of hip screening in Hong Kong. METHODS Records of children suspected of DDH and referred to our hospital between 1 January 2005 and 31 March 2010 were reviewed. The diagnosis was based on static and dynamic ultrasonography of the hips and/or radiographic f...

I. MAX SUM-RATE SCHEDULING: THE UPLINK CASE We have seen (in the presentation) that, for downlink (broadcast) channels, the strategy maximizing the sum-rate is one which only transmits to the user with best channel reception [1]. We now present a similar result for uplink (multi-access) channels [2]. Consider the single-cell multiuser uplink scenario where the signal received by the base statio...

OBJECTIVE To test the hypothesis that risk for dementia in late life is increased by a history of earlier psychiatric illness, and to examine the specificity of any such association. METHODS Frequency of earlier treated psychiatric illness was established by record searches and informant histories for all persons aged over 60 who were entered on the Camberwell dementia case register over a 2-...
