The purpose of this study is to clarify the presence of so much insoluble microparticles in the injections and to confirm the usefulness of the final filter for its removal. The test drugs used were Doyle 1 g vial, Cefotax 1 g vial, Minomycin 100 mg vial, Omegacin 0.3 g vial, Maxipime 1 g vial, Rocephin 1 g vial, Isovorin 25 mg vial, Diamox 500 mg vial and Fungizone 50 mg vial. 1) An appropriat...

Remote ischemic conditioning (RCond) induced by short periods of ischemia and reperfusion of an organ or tissue before myocardial reperfusion is an attractive strategy of cardioprotection in the context of acute myocardial infarction. Nonetheless, its mechanism remains unknown. A humoral factor appears to be involved, although its identity is currently unknown. We hypothesized that the circulat...

RATIONALE Endothelial activation and apoptosis release membrane-shed microparticles (EMP) that emerge as important biological effectors. OBJECTIVE Because laminar shear stress (SS) is a major physiological regulator of endothelial survival, we tested the hypothesis that SS regulates EMP release. METHODS AND RESULTS EMP levels were quantified by flow cytometry in medium of endothelial cells ...

This paper describes an acoustic trap consisting of a multi-foci Fresnel lens on 127 μm thick lead zirconate titanate sheet. The multi-foci Fresnel lens was designed to have similar working mechanism to an Axicon lens and generates an acoustic Bessel beam, and has negative axial radiation force capable of trapping one or more microparticle(s). The fabricated acoustic tweezers trapped lipid part...

Sera from 2,148 patients were tested with a third-generation microparticle enzyme immunoassay (MEIA), a confirmatory assay, and a reverse transcription-PCR. Overall, 85.6% of reactivities were confirmed, 13.2% were shown to be unspecifically reactive, and 1.2% were indeterminate. The rate of confirmed MEIA reactivities clearly depended on the strength of the reactivity.

When a laser beam scatters from a microparticle whose shape deviates from that of a sphere, a number of partial waves of the incident beam couple to a given partial wave of the scattered and interior fields. As a result, partial-wave coupling caused by small surface irregularities of a liquid droplet provides the mechanism for exciting low-radial-order morphology-dependent resonances.

A chip with which to manipulate microparticles using wireless power transfer and pulse-driven dielectrophoresis has been designed and fabricated using a 0.18-μm CMOS process. The chip enables microparticle manipulation under a 0.7-V power supply and a 13-MHz clock, which are generated on the chip by means of an on-chip coil, a rectifier, and a Schmitt trigger circuit.

Metal-capping of one hemisphere of a nano or microparticle breaks the particle’s optical symmetry, allowing its orientation to be tracked using fluorescence and reflection. Tracking orientation and rotation allows the torques acting on the particles be inferred. In addition to serving as rotational nanoviscometers these probes report on local Brownian, magnetic and biomechanical torques. r 2005...

The marginal fracture toughness of several types of composite resins was determined by means of the rattler test. Microparticle-filled resins showed significantly higher marginal fracture toughness than conventional composites. Posterior restorative composites were intermediate between MFRs and conventional composites. Amalgams were inferior to restorative resins. These data correspond with the...
