Abstract: The invention provides for tripyrrane compounds of the formula ##STR1## wherein: each Q represents, typically, an alkyl group, cycloalkyl group, aryl group, or a heteroaryl group; and each R represents hydrogen, an alkyl group, alcohol group, or a carbonyl-containing group.Additionally, there are described methods to prepare such compounds, for example, comprising the steps of:(a) reacting a compound of the formula:Q--CHO or Q--CH(OS)(OS')wherein S and S' are independently lower alkyl, an aryl group containing from 5 to 14 ring atoms, and --(CH.sub.2).sub.n -- where n =2-4;with a stoichiometric excess of a pyrrole having the formula: ##STR2## in the presence of a catalytic amount of an acid; (b) removing the unreacted pyrrole or any other solvents used in (a) by evaporation to form a residue; and(c) treating the residue to remove high molecular weight polymeric materials and the corresponding dipyrromethane by-product, leaving the desired compound.

Abstract: Methods for diagnosing thrombosis are disclosed. The methods comprise contacting a biological fluid of a subject with an antibody which binds specifically to the peptide liberated when thrombin receptors are activated.

Abstract: An occlusive implant delivery assembly includes a rapid response decoupling or detachment mechanism that does not effect significant migration of the implant during release. The assembly includes an occlusive implant device, such as an embolic coil, a pusher or device to carry the implant to the selected location, and an expandable coupling-decoupling mechanism for releasing the implant at the selected site. The mechanical construction provides rapid release times. In addition, the releasing mechanism generally operates without exerting any significant force on the implant, thereby avoiding any significant displacement of the implant during release.

Abstract: The present invention is directed to methods of obtaining plant-derived delipidated extracts that inhibit apoptosis, the extracts obtained, compositions containing said extracts and methods of using said compositions. FIG. 11 is a bar graph which illustrates a lower incidence of diarrhea in rats treated with methotrexate and fed a diet of compositions of the claimed invention as compared to controls.

Abstract: A drive device for driving a matrix-type LCD apparatus comprises a voltage signal supply means for outputting a plurality of voltage signals with different levels. The voltage signals have alternately positive and negative levels with respect to an AC reference voltage applied to a counter-electrode of the LCD apparatus. The AC reference voltage is approximately 180.degree. out-of-phase with the voltage signals. The drive device also comprises a signal electrode drive means which selects one of the voltage signals depending upon an input digital video signal, and which supplies the selected voltage signal to a signal electrode of the LCD apparatus.

Abstract: This invention is a surgical device. It is a guidewire for use in a catheter and is used for accessing a targeted site within a system of lumen within a patient's body. The guidewire may be of a high elasticity metal alloy, preferably a Ni-Ti alloy, having specified physical parameters, and is especially useful for accessing peripheral or soft tissue targets. The "necked" guidewire tip also forms a specific parameter of the invention.

Abstract: Improvements in the existing procedures and materials for conduct of high gradient magnetic separation (HGMS) are disclosed. Superior superparamagnetic particles, optionally coated with a polysaccharide or other, usually organic, materials can be prepared in uniform compositions with homogeneous magnetizations. The coating can conveniently be conjugated to a specific binding moiety complementary to a biological material whose purification or separation is desired. In addition, plastic coated matrices which form superior magnetic gradient-intensifying supports are disclosed, along with improved methods and apparatus to conduct HGMS.

Abstract: Neutral lipids are provided characterized by binding to phorboid and ingenoid receptors. These lipids are found in a wide variety of cellular sources as well as milk and may be isolated by specific extraction and chromatographic procedures. Depending upon the source, the glycerides may be mono- or di-glycerides, wherein the total number of carbon atoms of the fatty acis is in the range of 18 to 26, so that the monoglyceride has a fatty acid of at least 18 carbon atoms, while the di-glyceride has a fatty acid of at least 14 carbon atoms. The long chain fatty acids have at least one site of olefinic unsaturation.
