Suppression of natural killer (NK) cell activity of spleen cells by thymocytes
(Elsevier, 1981-02)
The in vitro influence of thymus cells on natural killer cell activity of spleen cells against prelabeled target cells (YAC-I and RL[male symbol]I) has been studied in syngeneic as well as in allogeneic murine models. In ...
Fusion of mercury a new certified standard for differential scanning calorimetry
(Elsevier, 1990-03)
From the results of adiabatic-calorimetric measurements, mercury has been certified as a standard reference material for temperature and enthalpy of fusion for differential scanning calorimetry. The fusion temperature is ...
Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
Computational analysis of unassigned high-quality MS/MS spectra in proteomic data sets
(WILEY-VCH Verlag, 2010-07)
In a typical shotgun proteomics experiment, a significant number of high-quality MS/MS spectra remain “unassigned.” The main focus of this work is to improve our understanding of various sources of unassigned high-quality ...
Hydroxylation of benzo[a]pyrene and binding of (-)trans 5-7,8-dihydroxy-7,8-dihydrobenzo[a]pyrene metabolites to deoxyribonucleic acid catalyzed by purified forms of rabbit liver microsomal cytochrome P-450 : Effect of 7,8-benzoflavone, butylated hydroxytoluene and ascorbic acid
(Elsevier, 1980-06-15)
The catalytic activities of hepatic microsornes from untreated, phenobarbital-treated and 3-methylcholanthrene-treated adult rabbits with respect to benzo[a]pyrene hydroxylation and the activation of (-)(rflw-7,8-dihydro ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Effect of Coadsorbed Water on Deep Oxidation Mechanisms: Temperature-Programmed Reactions of Benzene and Hydroxyl on the Pt(111) Surface
(Kluwer Academic Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2004-03)
The deep oxidation of benzene by preadsorbed hydroxyl on the Pt(111) surface has been characterized using temperature-programmed reaction spectroscopy. A mechanism for benzene oxidation in the presence of coadsorbed water ...
