Here, the authors describe playback studies on the alarm call system of two colobine species, the King colobus (Colobus polykomos) of Taï Forest, Ivory Coast, and the Guereza colobus (C. Guereza) of Budongo Forest, Uganda. Both species produce two basic alarm call types, snorts and acoustically variable roaring phrases, when confronted with leopards or crowned eagles. OBJECTIVE: To assess Australian radiation and medical oncologists\' self-reported knowledge about and attitudes towards a range of non-traditional therapies used by people with cancer.DESIGN: Postal survey during May and June 1997 of all 265 radiation and medical oncologists practising in Australia.PARTICIPANTS: 161 oncologists returned surveys (61% response rate).MAIN OUTCOME MEASURES: Oncologists\' own level of knowledge, and, for each known therapy, their perceptions of its likely harm or benefit in patients being treated curatively and palliatively, and of the prevalence of use among their patients.RESULTS: Oncologists reported knowing most about acupuncture, antioxidant therapy and meditation and least about cellular therapy, magnetotherapy and psychic surgery. The therapies most likely to be considered helpful were meditation, acupuncture and hypnotherapy. Those most likely to be considered harmful were coffee enemas, psychic surgery, Iscador therapy and diet therapies. The associations between nonsteroidal anti-inflammatory drugs (NSAIDs) and the presence and complications of gastroduodenal erosions and ulcers are well established. Evidence that acid aggravates NSAID-induced injury provides a rationale for minimising such damage by acid suppression. Other strategies discussed include avoidance of NSAIDs or minimising their dosage, selecting NSAIDs known to cause less damage, and co-prescription of various agents. Sequence analysis of human immunodeficiency virus type 1 (HIV-1) from 74 persons with acute infections identified eight strains with mutations in the reverse transcriptase (RT) gene at positions 41, 67, 68, 70, 215, and 219 associated with resistance to the nucleoside analogue air Max zidovudine (AZT). Follow-up of the fate of these resistant HIV-1 strains in four newly infected individuals revealed that they were readily replaced by sensitive strains. The RT of the resistant viruses changed at amino acid 215 from tyrosine (Y) to aspartic acid (D) or serine (S), with asparagine (N) as a transient intermediate, indicating the establishment of new wild types. The primary objective of this study was to determine the complete remission (CR) rate achieved with the air Max Nz FLAG (fludarabine phosphate, cytarabine and granulocyte colony-stimulating factor) regimen in patients with relapsed or refractory acute myeloid leukaemia (AML) or de novo refractory anaemia with excess of Air Max Thea blasts air Max Thea Nz in transformation (RAEB-t). Secondary objectives were to evaluate survival and toxicity. Induction treatment consisted of between one and two courses of FLAG.
