June 2009 Ongoing requirements for additional insight and CGMPcompliant measurement have led to interest in new technologies that can be applied to the analysis of many different types of particle-containing fluids. Micro-Flow imaging (MFI) is a robust, versatile, and intelligent vision technology that is increasingly used for evaluating populations of microparticles encountered during bioformu...

Pre-shaped mesoporous amorphous rice husk ash (RHA) and MCM-41 derived from RHA as a silica source were transformed into MFI-type zeolites using two different structure-directing agents. Tetrapropylammonium hydroxide (TPAOH) was utilized as an alkali source for silica dissolution and structure control during the direct transformation of RHA into zeolite. A monopropylamine (PA)-containing alkali...

This paper presents a new moving force identification (MFI) algorithm that uses measured accelerations to infer applied vehicle forces on bridges. Previous MFI algorithms use strain or deflection measurements. Statistics of the inferred are used in turn as indicators global bridge damage. The acceleration-based (A-MFI) is validated through numerical simulations with coupled vehicle-bridge dynam...

The authors developed a computer-aided diagnostic (CAD) scheme for classifying focal liver lesions (FLLs) as liver metastasis, hemangioma, and three histologic differentiation types of hepatocellular carcinoma (HCC), by use of microflow imaging (MFI) of contrast-enhanced ultrasonography. One hundred and three FLLs obtained from 97 cases used in this study consisted of 26 metastases (15 hyper- a...

OBJECTIVE Bacterial trigger possibly causes disease exacerbation in enthesitis-related arthritis (ERA) patients. Microbes initiate immune responses through Toll-like receptors (TLRs). We studied TLR expression on blood and SF monocytes and the effect of TLR ligands on peripheral blood (PB) mononuclear cells (PBMCs) in ERA patients. METHODS PB from 26 ERA patients and 19 healthy subjects and p...

PURPOSE Increased bone resorption is a hallmark of multiple myeloma and is attributable to osteoclast activation. Recent studies showed that the receptor activator of nuclear factor kappaB ligand (RANKL) is the key mediator of osteoclastogenesis and plays a crucial role in bone destruction in malignant bone disease. We found that human myeloma cells express RANKL and analyzed the association of...

BACKGROUND Flow cytometry (FC) HLA-B27 typing is still used extensively for the diagnosis of spondyloarthropathies. If patient blood samples are stored for a prolonged duration, this testing can be performed in a batch manner, and in-house cellular controls could easily be procured. In this study, we investigated various methods of storing patient blood samples. METHODS WE COMPARED FOUR STORA...

A series of catalysts based on hybrid intergrowth structure zeolites MFI-MEL, MFI-MTW, and MFI-MCM-41 are studied in the reaction olefins synthesis from dimethyl ether at atmospheric pressure a temperature 340 °C. The total acidity zeolite-based is shown to correlate with their activity. However, use zeolite MFI-MCM-41, which characterized by high content medium acid sites, additionally catalyz...
