We present the results of fitting ASCA spectra of six narrow-line Seyfert 1 (NLS1) galaxies with the ionised reflection models of Ross & Fabian (1993). We find that five of the galaxies (TON S 180, PKS 0558–504, Ark 564, Mrk 335 and PG 1244+026) are well fit by the ionised disc model, and these are often better fits than the alternative models considered. The sixth galaxy, NGC 4051, has additio...

To evaluate the effect of positive ionisation of inspired air on bronchial reactivity, 12 asthmatic children were twice challenged by exercise in random order. During one test positively ionised air (5-10 X 10(5) ions/cm) was breathed. All challenges were matched in terms of basal lung function and exercise tests were matched in terms of ventilation and respiratory heat loss. Exercise induced a...

Objective: To describe the toxicity of deliberate guanidine thiocyanate ingestion and it's treatment including dialysis. Case report: A 52-year-old male presented to hospital with abdominal pain after giving a history of ingesting bottled water. His initial vital signs and examination were normal. Soon after the patient became confused and agitated, necessitating intubation and ventilation for ...

Accepted for publication 23 March 1994 Abstract Changes in biliary lipid composition, pH, ionised calcium, total and unconjugated bilirubin, and cholesterol nucleation time of gall bladder bile samples were examined in six patients who had undergone subtotal or total colectomy between five months and seven years previously, and values were compared with those in control patients with no gall st...

The intravenous Na2EDTA infusion technique allows effective specific chelation of circulating Ca2+ leading to a progressive hypocalcaemia. Methods previously used were not described in detail and results obtained by monitoring total and free ionic calcium were not comparable due to differences in sampling and analysis. This paper describes a standardized EDTA infusion technique that allowed com...

Aims. We investigate the link between ionised Fe X-ray line emission and continuum emission in a bright nearby AGN, Mrk 766. Methods. A new long (433 ks) XMM-Newton observation is analysed, together with archival data from 2000 and 2001. The contribution from ionised line emission is measured and its time variations on short (5–20 ks) timescales are correlated with the continuum emission. Resul...
