Introduction: At high magnetic field strengths (≥3T) the RF wavelength becomes smaller than the sample size, making transmit magnetic field (B1) inhomogeneity more prominent. RF-shimming [1] and Transmit SENSE [2] have been proposed as methods to minimize this inhomogeneity. To take advantage of these methods it is important to accurately map the B1 field. Saturation prepared with 2 RApid Gradi...

Siglec-G is an inhibitory receptor on B1 cells. Siglec-G-deficient mice show a large B1 cell expansion, owing to higher BCR-induced Ca(2+) signaling and enhanced cellular survival. It was unknown why Siglec-G shows a B1 cell-restricted inhibitory function. With a new mAb we could show a comparable Siglec-G expression on B1 cells and conventional B2 cells. However, Siglec-G has a different ligan...

Introduction B1 inhomogeneity in a human body increases as the strength of static magnetic field increases and the RF wavelength becomes smaller. Recently, various RF control methods have been developed to reduce B1 inhomogeneity. For example, some methods involve devices such as dielectric pads [1,2] or coupling coils [3,4], or techniques such as B1 shimming [5,6]. However, B1 inhomogeneity st...

Fong, Choong Yi, Linhua Pang, Elaine Holland, and Alan J. Knox. TGF-b1 stimulates IL-8 release, COX-2 expression, and PGE2 release in human airway smooth muscle cells. Am J Physiol Lung Cell Mol Physiol 279: L201–L207, 2000.—We have recently shown that endogenous prostanoids are critical in bradykinin-stimulated interleukin (IL)-8 release from human airway smooth muscle (ASM) cells. In this stu...

Let A be a non empty set, let B be a set, let B1 be a set, and let y1 be a function from B1 into A. Let us assume that B1 ⊆ B. The functor cylinder0(A,B,B1, y1) yields a non empty subset of A B and is defined by: (Def. 1) cylinder0(A,B,B1, y1) = {y : B → A: y B1 = y1}. Let A be a non empty set and let B be a set. A non empty subset of AB is said to be a thin cylinder of A and B if: (Def. 2) The...

Signaling through the semaphorin 4D (Sema4D) receptor plexin-B1 is modulated by its interaction with tyrosine kinases ErbB-2 and Met. In cells expressing the plexin-B1-ErbB-2 receptor complex, ligand stimulation results in the activation of small GTPase RhoA and stimulation of cellular migration. By contrast, in cells expressing plexin-B1 and Met, ligand stimulation results in an association wi...

We have synthesized bulk Mg(B1−xCx)2 from a mixture of elemental Mg, B, and the binary compound B4C. Carbon incorporation was dramatically improved by a two step reaction process at an elevated temperature of 1200 C. This reaction process results in a solubility limit near x∼0.07. We found that impurities in the starting B cause an additive suppression of Tc. We combine these data with Tc and H...

In a field test to examine attractancy of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), relative to release rates, equal moles of racemic ceralure B1 and trimedlure isomer C were compared on cotton wicks. Data were collected at 2, 4, and 7 d. The substrates were analyzed for longevity and overall persistence in the field. Ceralure B1 was equally attractive as trimedlure C for the fir...

Kinins exert cardioprotective effects via 2 G-protein-coupled receptors, B1 and B2. Using B1 kinin receptor gene knockout mice (B1-/-), we tested the hypotheses that the B1 receptor plays an important role in preservation of cardiac function, whereas lack of B1 may accelerate cardiac remodeling and dysfunction after myocardial infarction, and that B2 receptors may compensate for lack of B1, whe...
