Preferred isolates are more susceptible to a number of sterol synthesis and metabolic inhibitors relative to wild type isolates. Further provided are methods to identify sterol methyltransferase inhibitors and methods to screen for antifungals or metabolic inhibitors which are not normally permeable to the fungal cell.

Abstract: A guide catheter includes a body and a centering mechanism. The body has an elongatable section and a lumen with a stop. The centering mechanism is a plurality of bias elements that forms a self-expanding basket attached to the body so that the elongatable section is within the basket. A straightening catheter engages the stop to stretch the elongatable section and to flatten the basket against the body. The guide catheter can be inserted into a vessel and the centering mechanism can be positioned at a desired treatment site by means of an over-the-wire guidewire system. The straightening catheter can be removed to allow the self-expanding basket to center the guide catheter in the vessel. A dosing device can then be inserted into the guide catheter and located at the centered basket to deliver the brachytherapy to prevent restenosis.

Abstract: Devices and methods are disclosed for the percutaneous administration of a composition to a desired in vivo location.

Also described are polyclonal antibody preparations for use in methods for detecting APE and methods for modulating expression susceptibility of cells to apoptosis.

Abstract: Compositions and methods are disclosed for filling prostheses for implantation into human soft tissue. The compositions comprise at least one nonionic surfactant, such as a polysorbate, which can be provided to fill a physiologically compatible shell or containment sac of the prosthesis. The liquid compositions of the present invention have a relatively high viscosity and are quickly absorbed from body tissues, metabolized and excreted with no known adverse effect. The compositions can be injected into the physiologically compatible shell either before, during or after the surgical implantation procedure.

Abstract: Methods for screening for risk of Alzheimer's disease involve assaying for a guanine to thymine substitution at position 1924 of the gene encoding the human amyloid precursor protein. Also described are transgenic non-human mammals, especially transgenic mice, harboring an expressable gene sequence encoding human amyloid precursor protein having a phenyalanine for valine amino acid substitution in the transmembrane domain of the amyloid precursor protein.

Abstract: The invention provides a device having two components: a needle advancing apparatus slidable longitudinally along a catheter to advance needles into a tissue membrane, such as a blood vessel wall, around an opening in the membrane; and, a suture retrieval assembly insertable through the catheter beyond a distal side of the tissue membrane. The needle advancing apparatus advances suture through the tissue wall. The suture retrieval assembly grabs the suture on the distal side of the tissue membrane for extraction thereof through the opening in the tissue membrane. A method for suturing a membrane beneath the patient's skin is also disclosed.
