Pfalzer AC, Choi SW, Tammen SA, Park LK, Bottiglieri T, Parnell LD, Lamon-Fava S. S-adenosylmethionine mediates inhibition of inflammatory response and changes in DNA methylation in human macrophages. Physiol Genomics 46: 617–623, 2014. First published July 15, 2014; doi:10.1152/physiolgenomics.00056.2014.—S-adenosylmethionine (SAM), the unique methyl donor in DNA methylation, has been shown to...

Smoothing approaches to the Simultaneous Localization and Mapping (SLAM) problem in robotics are superior to the more common filtering approaches in being exact, better equipped to deal with non-linearities, and computing the entire robot trajectory. However, while filtering algorithms that perform map updates in constant time exist, no analogous smoothing method is available. We aim to rectify...

The suppressive effects on acute alcoholic liver injury of S-adenosylmethionine (SAM) and the sake yeast, Saccharomyces cerevisiae Kyokai No. 9, have been shown previously. To enhance the suppression of acute alcoholic liver injury by sake yeast, we prepared SAM-accumulating sake yeast (SAM yeast). Male C57BL/6 mice that had been fed on a diet containing 0.25% SAM yeast or sake yeast for two we...

Ethylene, a gaseous hormone in plants, is involved in the regulation of a wide range of plant physiological processes, including leaf abscission, fruit ripening, and flower senescence (Yang and Hoffman, 1984). SAM or Adomet synthetase (ATP:L-methionine S-adenosyltransferase; EC 2.5.1.6) catalyzes the conversion of Met to SAM in the presence of ATP and Mg2+, which is the first step in ethylene b...

The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...

A further development of the synchronous array method (SAM) as a medium access control scheme for large-scale ad hoc wireless networks is presented. Under SAM, all transmissions of data packets between adjacent nodes are synchronized on a frame-byframe basis, and the spacing between concurrent cochannel transmissions of data packets is properly controlled. An opportunistic SAM (O-SAM) is presen...

Hydroxyapatite formation was examined at the surface of self-assembled monolayers (SAMs) modified with four functional groups, -COOH, -NH(2), -CH(3), and -OH. For COOH-SAM and NH(2)-SAM, scanning electron spectroscopic observation showed that flake-like sheet crystals covered the whole wafer and small broccoli-like crystals were observed occasionally on the flake-like crystal base layer. For CH...

Metabolism of levodopa via the enzyme catechol-O-methyltransferase requires S-adenosylmethionine (SAM) as a methyl donor. SAM caused Parkinson disease (PD)-like symptoms in rodents. Therefore, SAM could contribute to a decreased efficacy of levodopa in the long term. SAM levels were significantly reduced in levodopa-treated PD patients, but they showed increased enzyme methionine adenosyl trans...

This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...
