The whole cell variant of the patch clamp technique was used to investigate the actions of the polyamine amide spider toxin, argiotoxin-636, on the excitability of cultured dorsal root ganglion neurones. Synthesized argiotoxin-636 (0.1-100 microM) reduced neuronal excitability when applied to the extracellular environment by low pressure ejection or to the(More)
Pseudomonas aeruginosa is known to have an inducible uptake system for the enterobacterial siderophore enterobactin. In this work we have examined iron transport mediated by the biosynthetic precursor 2,3-dihydroxybenzoic acid and N-(2,3-dihydroxybenzoyl)-L-serine, a breakdown product of enterobactin. Iron complexed with 2,3-dihydroxybenzoyl-L-serine was(More)
Synthetic funnel web spider toxin (sFTX-3.3) is a polyamine amide analogue of FTX, a toxin fraction isolated from the venom of the funnel web spider, Agelenopsis aperta, that blocks P-type Ca2+ channels. The structures of these polyamine containing compounds are not identical: sFTX-3.3 contains an amide carbonyl oxygen that is absent from the predicted(More)
A polyamine component of Agelenopsis aperta spider venom designated FTX is reported to be a selective antagonist of P-type calcium channels in the mammalian brain. Consequently, this component has frequently been used as a pharmacological tool to determine the presence, distribution, and function of P-type channels in physiological systems. We describe(More)
A hybrid neural network-first principles modelling scheme is used in this paper, to model an induction motor and to develop a fault detection and isolation (FDI) scheme. The hybrid model combines a partial first principles model, which incorporates the available prior knowledge about the process being modelled, with a neural network which serves as an(More)
