Abstract:
Subjects at risk for developing cancer may be identified by obtaining samples of diagnostic cells from the subjects and determining a measure of cytotoxicity of the cells, the measure of cytotoxicity correlating negatively with the risk of developing cancer. The development of cancer may be prevented in subjects determined to be at risk for developing cancer by administering priming and activating agents to the subject, by increasing the expression of A 1 adenosine receptors in cells of the subject, and increasing the affinity of cells of the subject for A 1 adenosine receptor ligands. The preventative and diagnostic methods of the present invention may be carried out with kits and pharmaceutical liposomal formulations.
Abstract:
This invention relates to compounds of formula (I), Wherein R1 - R4 are defined in the Specification, their uses in the practice of medicine, their medicinal formulations, their use in medical diagnosis, and their preparation.
Abstract:
Methods for treating and preventing tissue injury and sepsis associated with a Yersinia pestis infection, particularly pneumonic plague, are provided. The methods of the invention comprise administering to a subject a therapeutically effective amount of an A1 adenosine receptor antagonist alone or in combination with a t least one additional therapeutic agent, including an antibiotic agent. The present methods find use in biodefense as a means of preventing and treating tissue injury a nd sepsis associated with Y. pestis infection, particularly pneumonic plague, in the event of a bioterrorist attack with this deadly bacterium.
