Actin polymerization in cellular oxidant injury
(Elsevier, 1991-08-01)
Microfilaments undergo an ATP-dependent disruption into shortened bundles following cellular exposure to oxidants. This phenomenon does not require a net change in the amount of polymerized actin. However, increased amounts ...
Entropy and heat capacity of europium(III) bromide from 5 to 340 K
(Elsevier, 1975-07)
The heat capacity of a polycrystalline sample of EuBr3 has been measured from 5 to 340 K and found to be without transitions in this region. Values of the thermodynamic functions Cp(T), {So(T) - So(5 K)}, and {Ho(T) - Ho(5 ...
Gas chromatographic separtion of low molecular weight fluorocarbons
(Elsevier, 1968)
Application of gas-solid chromatography techiques to the separation of low molecular weight fluorocarbons incorporates a number of advantages over previous analysis techniques. These advantages include isothermal operation ...
Progress in Practice: Exploring the Cooperative and Collaborative Dimensions of Group Learning
(Springer-Verlag; Springer-Verlag New York, Inc., 1996-03)
We all participate in a variety of groups as part of our daily lives, from families to social and work communities. As chemists, we are part of our college departments, our professional societies, our research groups, and ...
Conversion of dehydroepiandrosterone sulfate to androst-5-enediol-3-sulfate by soluble extracts of rat testis
(Elsevier, 1965-09)
3H-Androst-5-ene-17-one-3[beta]-y1 sulfate is converted to 3H-androst-5-ene-17[beta]-o1-3[beta]-y1 sulfate by soluble extracts of rat testis in the presence of added NADH2 or NADPH2.The conversion was approximately 4 times ...
Cycloaddition of vinyl aziridines with unsaturated substrates. A novel rearrangement of an unsaturated nitro compound.
(Elsevier, 1981)
Vinylaziridine undergoes reaction with electrophilic acetylenes and olefins to produce 7-membered azepine derivatives. With [beta]-nitro-styrene however, a novel rearrangement occurs, presumably via an ene reaction to ...
Probing the temperature sensitivity of induction time in latent cure epoxy resins
(John Wiley & Sons, Ltd, 2013-10)
Two dynamic viscosity datasets for epoxy resins cured at temperatures between 100 and 150 °C were re‐analyzed to compare the interpretation of gel times and activation energies using two mathematical models. © 2012 Society ...
Characterization of nucleic acid higher order structure by gas-phase H/D exchange in a quadrupole-FT-ICR mass spectrometer
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Nucleic acid higher order structure is of intense interest in antisense and antigene strategies toward novel chemotherapeutic agents. Understanding how structural characteristics affect solution-phase properties is essential ...
