The susceptibility of Xanthomonas maltophilia strains to beta-lactams is known to vary according to the type of growth media used. We have assayed the divalent cation content of various susceptibility testing media and correlated this with the susceptibility to imipenem of 30 strains of X. maltophilia, by calculating the IC50. No correlation was found with(More)
BACKGROUND Aluminium toxicity as a cause of dementia, osteodystrophy and anaemia in patients receiving renal dialysis was first described in the 1970s and led to the regular monitoring of aluminium in plasma and dialysate water. However, aluminium phosphate binders have now been replaced by calcium-based binders or sevelamer and reverse osmosis (RO) water(More)
Threat-relevant stimuli such as fear faces are prioritized by the human visual system. Recent research suggests that this prioritization begins during unconscious processing: A specialized (possibly subcortical) pathway evaluates the threat relevance of visual input, resulting in preferential access to awareness for threat stimuli. Our data challenge this(More)
The Flåt Nickel mine at Evje in southern Norway was mined extensively from 1914 to 1945 with little regard for any potential environmental effect. Much of the ore extracted was smelted at a site adjacent to the river Otra south of Evje. Recent studies have revealed heavy metal pollution in the land surrounding the smelter and in water draining from the mine(More)

The present study was undertaken to establish the relationship between serum and urine silicon and improve renal function and examine whether the increased urinary excretion of aluminium observed after successful renal transplantation was associated with silicon. The changes in silicon and aluminium concentrations in serum and urine were measured in 15(More)
Urinary aluminium was measured in 48 patients with primary graft function for 14 days following renal transplantation. The plasma aluminium prior to transplantation was greater in those prescribed aluminium-containing phosphate binders (1.7 +/- 0.2 vs 0.6 +/- 0.2 mumol/L, P less than 0.05) and correlated with the duration of dialysis therapy (r = 0.42, P(More)
Protoporphyrin and zinc-protoporphyrin were measured in the erythrocytes of normal subjects, workers exposed to lead and patients with iron deficiency and erythropoietic protoporphyria (EPP). Results showed significantly higher levels of zinc-protoporphyrin in the lead-exposed workers (P < 0.0001), patients with iron deficiency (P < 0.0001) and EPP patients(More)
Urinary aluminium excretion was prospectively monitored during the first year following first cadaver renal allograft transplantation in 79 consecutive patients. Plasma and urinary aluminium concentrations steadily declined with time. Thirty-five patients had 0-1 episodes of acute graft rejection compared to 44 with two or more rejections; more of the(More)
