Disclosed herein are novel medical devices, particular well-suited for sustained delivery of therapeutically-significant substances. Also disclosed are methods of making and using these delivery devices. Using these devices and methods, the present invention teaches sustained, targeted and reversible delivery of immunostimulating agents, as well as therapeutic agents such as enzymes, hormones and neurotransmitters, to name but a few.

Sustained delivery device and methods of making and using the same

Homozygous gene replacement can be created in unicellular diploid organisms by individually targeting each allele of a gene with genetic constructs containing two different and independent selectable markers. Selection for both markers indicates replacement of both alleles of the gene, or portion thereof. The method can be used to study gene function in these organisms and to create mutant organisms such as attenuated strains of parasitic protozoans for use in live vaccines.

Double targeted gene replacement in unicellular diploid organisms
