A method is presented that improves the effectiveness of RF-spoiling whenever an image consists of the averaging of several identical single acquisitions. Using this method, it becomes possible to reduce the necessary moment of the spoiler gradient by a factor equal to the number of averages. The idea is to perform the collection of k-space lines such that the averaging takes over a part of the...

New projects being implemented or planned at CERN, such as the LHC Injectors Upgrade (LIU), High-Luminosity (HL-LHC) Future Circular Collider (FCC), motivate change of several architectural paradigms in Low Level RF systems (LLRF). In upgraded Super Proton Synchrotron (SPS) LLRF, distribution RF, revolution frequency, settings and synchronization timings will rely on a deterministic link, White...

INTRODUCTION Rituximab (RTX) therapy of rheumatoid arthritis (RA) exhibits enhanced effectiveness in seropositive patients. Using patient sera, we tested if this improved efficacy was associated with enhanced RTX mediated complement-dependent cytotoxicity (RTX-CDC). METHODS We developed an in vitro assay for RTX-CDC using patient sera and the Daudi human B cell line. Using propidium iodide up...

The cysteinyl leukotrienes, leukotriene (LT) C(4), LTD(4), and LTE(4), are lipid mediators that have been implicated in the pathogenesis of several inflammatory processes, including asthma. The human LTD(4) receptor, CysLT(1)R, was recently cloned and characterized. We had previously shown that HL-60 cells differentiated toward the eosinophilic lineage (HL-60/eos) developed specific functional ...

A method of moment with an enhanced model to design high-temperature superconductor (HTS) RF surface coils for magnetic resonant image (MRI) is presented. The resonant frequency and quality factor ( ) of HTS RF spiral coils are simulated using this method. The agreements of resonant frequencies and s between the simulation and measurement are excellent with differences less than 1% and 3%, resp...

Our previous studies showed that urinary Tamm-Horsfall glycoprotein (THP) potently enhanced polymorphonuclear neutrophil (PMN) phagocytosis. However, the domain structure(s), signaling pathway and the intracellular events responsible for THP-enhanced PMN phagocytosis remain to be elucidated. THP was purified from normal human urine. The human promyelocytic leukemia cell line HL-60 was induced t...

We investigate the collapse of granular rodpiles as a function of particle (length/diameter) and pile (height/radius) aspect ratio. We find that, for all particle aspect ratios below 24, there exists a critical height Hl below which the pile never collapses, maintaining its initial shape as a solid, and a second height Hu above which the pile always collapses. Intermediate heights between Hl an...

We studied the effect of hematopoietic growth factors (granulocyte-macrophage colony-stimulating factor [GM-CSF], granulocyte [G]-CSF, interleukin (IL)-1, IL-3, IL-5, IL-6, and macrophage [M]-CSF) on differentiation and functional activity of human eosinophilic HL-60 cells (Eos-HL-60) and compared them with effects on parental HL-60 promyelocytic leukemia cells. Purified biosynthetic GM-CSF and...

background : who focuses on developing health literacy (hl) referring to cognitive and social skills. our objectives were to develop a scale for evaluating the hl level of thai childhood overweight, and develop a path model of health behavior (hb) for preventing obesity. study design: a cross-sectional study. methods : this research used a mixed method. overall, 2,000 school students were aged ...
