Abstract: Method and apparatus for using magnetic susceptibility measurements to detect ferromagnetic foreign bodies (FFBs) in the eye. The method involves having the patient rotate his or her eyes, modulating the orientation and/or location of the FFB  in relation to the sensing apparatus. This changing orientation or position will modulate the magnetic susceptibility signal from the FFB, without substantially changing the magnetic susceptibility response of the patient's body tissues. Consequently, modulation of the magnetic signal due to the motion of the eye will indicate the presence of an FFB in the eye. Eye movement may also be used in conjunction with the detection of ferromagnetic foreign bodies by means other than magnetic susceptibility measurements, such as x-rays and ultrasound.

Abstract: The present invention provides methods and compositions that enable the experimental determination as to whether any gene in the genome of a diploid  pathogenic organism is essential, and whether it is required for virulence o r pathogenicity. The methods involve the construction of genetic mutants in which one allele of a specific gene is inactivated while the other allele of  the gene is placed under conditional expression. The identification of essential genes and those genes critical to the development of virulent infections, provides a basis for the development of screens for new drugs against such pathogenic organisms. The present invention further provides Candida albicansgenes that are demonstrated to be essential and are potential targets for drug screening. The nucleotide sequence of the target genes can be used for various drug discovery purposes, such as expression of  the recombinant protein, hybridization assay and construction of nucleic aci d arrays. The uses of proteins encoded by the essential genes, and genetically  engineered cells comprising modified alleles of essential genes in various screening methods are also encompassed by the invention.
