An insoluble complex was synthesized by the reaction of sodium diethyldithiocarbamate trihydrate (DDTC) with CdCl2 X 2.5 H2O (Cd). Elemental analyses of the product yielded a percent composition of each element which was consistent with the postulated structure of two mole equivalents of (DDTC)- and one mole equivalent of Cd++. The DDTC formed a complex with 11 other metal ions tested, but not ...

We incorporate fault tolerance in designing reliable and scalable overlay networks to support topicbased publish/subscribe communication. We propose a new family of optimization problems, named MinAvg-kTCO, that captures the trade-offs among several key dimensions including fault tolerance, scalability, performance, and message dissemination. Roughly speaking, the MinAvg-kTCO problem is: use th...

Many Golgi glycosyltransferases are type II membrane proteins which are cleaved to produce soluble forms that are released from cells. Cho and Cummings recently reported that a soluble form of alpha1, 3-galactosyltransferase was comparable to its membrane bound counterpart in its ability to galactosylate newly synthesized glycoproteins (Cho,S.K. and Cummings,R.D. (1997) J. Biol. Chem., 272, 136...

The noncovalent complexes between the BlaI protein dimer (wild-type and GM2 mutant) and its double-stranded DNA operator were studied by nanospray mass spectrometry and tandem mass spectrometry (MS/MS). Reproducibility problems in the nanospray single-stage mass spectra are emphasized. The relative intensities depend greatly on the shape of the capillary tip and on the capillary-cone distance. ...

Ozone line parameters have been retrieved from high-resolution Fourier transform spectra in the 5-µm and 10-µm spectral regions using a H-shaped cell with two parallel paths described first paper of series (Multi-spectral investigation ozone: Part I. Setup & uncertainty budget). The experimental arrangement allows for quasi simultaneous acquisition at 5 µm 10 consistent ozone pressure. A multis...

GM2 activator protein (GM2AP) is a specific protein cofactor that stimulates the enzymatic hydrolysis of the GalNAc from GM2, a sialic acid containing glycosphingolipid, both in vitro and in lysosomes. While phospholipids together with glycosphingolipids are important membrane constituents, little is known about the possible effect of GM2AP on the hydrolysis of phospholipids. Several recent rep...
