The rapid and sensitive detection of Salmonella typhymurium based on the use of a polyclonal antibody immobilized by the Langmuir-Blodgett method on the surface of a quartz crystal acoustic wave device was demonstrated. The binding of bacteria to the surface changed the crystal resonance parameters; these were quantified by the output voltage of the sensor… (More)
The potential use of weapons of mass destruction (nuclear, biological or chemical) by terrorist organizations represents a major threat to world peace and safety. Only a limited number of vaccines are available to protect the general population from the medical consequences of these weapons. In addition there are major health concerns associated with a… (More)
A widely applicable three-dimensional QSAR pharmacophore model for antimalarial activity was developed from a set of 17 substituted antimalarial indolo[2,1-b]quinazoline-6,12-diones (tryptanthrins) that exhibited remarkable in vitro activity (below 100 ng/mL) against sensitive and multidrug-resistant Plasmodium falciparum malaria. The pharmacophore, which… (More)
ASSLNIA, a peptide selected for murine myofibers using phage display technology, was immobilized onto an acoustic wave sensor. The sensor responded to murine and feline muscle homogenates indicating crosspieces interactions. Kidney, liver, and brain preparations produced insignificant responses.
Previous work has suggested that a free radical mechanism is involved in some types of muscle fatigue and that there can be free radicals released extracellularly. Because muscle fatigue may be an important factor in respiratory failure, the authors tested the hypothesis that increased concentrations of free radicals could be detected in the blood of… (More)
The artemisinin derivatives artelinic acid and artesunic acid are members of a class of compounds that have shown promise for the treatment of multidrug resistant strains of Plasmodium falciparum. Unfortunately, these compounds exhibit poor solubility and stability in aqueous solution. The research presented herein was conducted to determine whether… (More)
