EXAMPLES. (i) The multiplicative group A = Gm is the algebraic group whose points over a field are the nonzero elements of the field. Then for any field K, Tor Gm(K) are the roots of unity contained in K. (ii) A = Gm×Gm then Tor(A) = Tor(Gm)×Tor(Gm) = {(x, y) : x, y ∈ K are roots of unity}. (iii) Let A be an elliptic curve. Over the complex numbers we can uniformize A as A = C/L where L is a la...

Phosphoinositol turnover, diacylglycerol generation, protein kinase C (PK-C) activity, and intracellular cyclic nucleotides were studied in an established human leukemia cell line, HL-60, in response to one of the hematopoietic cytokines, granulocyte-macrophage colony-stimulating factor (GM-CSF). Continuous exposure of HL-60 cells to GM-CSF induced the cell differentiation that was evaluated by...

Since the brain's gray matter (GM) and white matter (WM) metabolite concentrations differ, their partial volumes can vary the voxel's ¹H MR spectroscopy (¹H-MRS) signal, reducing sensitivity to changes. While single-voxel ¹H-MRS cannot differentiate between WM and GM signals, partial volume correction is feasible by MR spectroscopic imaging (MRSI) using segmentation of the MRI acquired for VOI ...

We have investigated, both analytically and numerically, accreting supermassive black hole binaries as they inspiral due to gravitational radiation elucidate the decoupling of from their disks inform future multi-messenger observations these systems. Our numerical studies evolve equal-mass initial separations $100 GM/c^2$ until merger, resolving scales small $\sim0.04 GM/c^2$, where $M$ is tota...

Granulocyte-macrophage colony-stimulating factor (GM-CSF) induces various functions, including the proliferation and differentiation of a broad range of hematopoietic cells. We previously reported that at least two distinct pathways are involved in human GM-CSF receptor signaling; both require the box 1 region of the common beta subunit (beta c). This region is essential for the activation of J...

Pulmonary alveolar proteinosis (PAP) is a rare disorder of unknown origin characterized by alveolar fillings with periodic acid-Schiff (PAS)-positive material mainly consisting of phospholipids. Mice defective in the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene or the GM-CSF/interleukin (IL)-3/IL-5-receptor common beta chain (beta c) demonstrate a pathology resembling PAP. A r...

G-CSF and GM-CSF play important roles in regulating neutrophil production, survival, differentiation, and function. However, we have shown previously that G-CSF/GM-CSF double-deficient [knockout (KO)] mice still develop a profound neutrophilia in bone marrow and blood after infection with Candida albicans. This finding suggests the existence of other systems, which can regulate emergency neutro...

Gentamicin (GM) is an effective antibiotic against severe gram-negative infections. However it can produce nephrotoxicity in human. Reactive oxygen species (ROS) have been proposed as the causative factors of the renal side effects the drug. This study was performed to investigate the protective role of antioxidant vitamins against GM-mediated nephropathy in an in situ model of isolated rat kid...

BACKGROUND The Platelia Aspergillus Ag assay (Bio-Rad) is designed for detecting Aspergillus galactomannan (GM) and is widely used for diagnosing invasive aspergillosis but is hampered by variable occurrences of unreproducible positive results. Frequency and origin of these unreproducible results have not been formally studied. METHODS Different technicians simultaneously performed four tests...
