The present invention provides compositions suitable for use as biomarkers of vulnerable plaques as well as methods for the use of such compositions. In preferred embodiments, specific molecular imaging agents are provided that permit the selective identification of vulnerable plaques in coronary and other arteries using non-invasive imaging methods. Such specific molecular imaging agents comprise a binding partner linked to a detectable label that can be used in vivo to visualize vulnerable plaques. In certain preferred embodiments, the binding partner is a peptide that binds selectively to a component of a vulnerable plaque. In other preferred embodiments, the binding partner is an antibody that binds selectively to a component of a vulnerable plaque. In other preferred embodiments, the binding partner is a portion of a polypeptide displayed by a bacteriophage that binds selectively to a component of a vulnerable plaque. In preferred embodiments, the component of a vulnerable plaque is myeloperoxidase or a portion thereof.
摘要:
Alkaline batteries are disclosed that advantageously include separators comprising at least one porous layer of fine fibers having a diameter of between about 50 nm and about 3000 nm that provide improved combinations of reduced thickness, dendritic barrier against short-circuiting and low ionic resistance as compared with known battery separators. The fine fibers show improved wet-ability in the alkaline electrolytes.

This invention relates to novel processes comprising a protective polymer layer in the fabrication of electronic devices using thick film pastes. The protective polymer layer is fabricated from materials which are insoluble after irradiation in the ester-type solvents contained in the thick film paste. By appropriate selection of protective film polymers, the protective film can be compatible with the thick film paste.
摘要:
An radio frequency (RF)/microwave power amplification circuit is disclosed herein having improved power and frequency characteristics. The RF power circuit is characterized by having the output capacitance of the device resonate with a shunt inductance that is physically closer to the device than provided in conventional RF power circuits. This is realized by mounting a direct current (DC) bypass capacitor directly on the same metalized pad that the device terminal is mounted on. By doing this, the inductance associated with a wire bond connection from the device to the capacitor is eliminated or at least reduced. Also disclosed is a dual cell power circuit that consists of matching the impedance characteristics of the active cells to each other by adjusting the circuit parameters in which the active devices interact with. In addition, an RF power circuit is disclosed that includes a pair of vertical cells in a parallel relationship formed on a thin semiconductor to cause more current flow through a metal layer rather than the lossy substrate. Furthermore, a novel metal-dielectric-metal chip capacitor is disclosed that is fabricated on a refractory metal substrate, which results in a high quality factor (Q) for the capacitor. The capacitor has contacts to both capacitor plates by way of its top metallization surfaces, and access to one of the plates through the bottom, i.e. the mounting surface of the capacitor. Additionally, a high power device is disclosed that encompasses at least some or all of the techniques described above to achieve an amplification that exhibits both high power and high cutoff frequency characteristics.
