Benzobicyclo[8.4.0(1,6)0(8,13]tetradecenones: ring CD-taxoid models by planar tether controlled cycloaddition.

[structure: see text]. A general approach to functionalized hexahydroanthracene dione skeletons is described. The planar dicarbonyl triene 15 cyclized spontaneously upon oxidation of the precursor diol 14 to the tricyclicdiketone 16.

Hospital accounting and information systems: a critical assessment.

Public sector organisations seem to be caught up in the global wave of 'neo-Thatcherism'. As such, they are being held 'accountable' today by their respective government finance departments for the costs and benefits of the services they provide to the general public. As the public purse tightens, hospitals (and related health service units) more and more compete with other public sector organisations (old-age pensions and services, post-secondary education, day-care centres, port authorities, unemployment insurance, parks and recreation, elite sport programs, aboriginal peoples aid and development, and so on) for a diminishing piece of what seems a smaller and smaller pie.

Passive transfer of HIV antibody by hepatitis B immune globulin.

Two newborns of mothers carrying hepatitis B and at high risk for human immunodeficiency virus (HIV) infection developed HIV-positive test results by enzyme-linked immunosorbent assay and Western blot tests after birth. Both had been administered hepatitis B immune globulin within 48 hours of birth. Serological tests detected HIV antibody as long as 17 days after birth.

Postnatal development of the cutaneous flexor reflex: comparative study of preterm infants and newborn rat pups.

Cutaneous flexor reflex thresholds have been used as a measure of somatosensory function: the authors measured threshold in preterm infants and newborn rat pups. Preterm infants of less than 30 weeks postconceptional age (PCA) had very low thresholds of less than 1.0 g, but by 37.

A new approach to design and use of management information.

Information, that is both accurate and timely, is probably the most important resource needed by managers to make sound decisions regarding the problems and issues facing their organizations. Unfortunately, sophisticated information systems often fail to meet this need. Managers complain that the data produced by information systems arrive too late, are too general and lack accuracy.
