An attempt to improve the SOS chromotest responses

Journal of Applied Toxicology, 1993
AbstractThe SOS Chromotest was carried out on leachates of ten industrial wastes with the standard procedure and a miniaturized version with microplates. The two methods gave identical results in nine samples (eight negative and one positive). A simple additional manipulation is described for the identification of the false positive response that is ...

Induction of the SOS Response by IS1 Transposase

Journal of Molecular Biology, 1994
We find that IS1 transposase, like that of Tn10, can induce the SOS response when produced at high levels. Most of the activity (> 80%) requires IS1 ends in cis to the transposase gene and depends strictly on the presence of RecBCD function. This implies that processing of transposase-induced cleavages is responsible for generating the response ...

So not mothers: responsibility for surrogate orphans

Journal of Medical Ethics, 2018
The law ordinarily recognises the woman who gives birth as the mother of a child, but in certain jurisdictions, it will recognise the commissioning couple as the legal parents of a child born to a commercial surrogate. Some commissioning parents have, however, effectively abandoned the children they commission, and in such cases, commercial surrogates ...

Response: Not So…

The Review of Politics, 2004
It was not the exquisite self-consciousness of a Henry James that I had in mind when I wondered about equality and hierarchy in Locke, but the assertive self-consciousness or—what is for Locke ultimately the same—self-interestedness of an Andrew Carnegie, as exemplified both in the acquisition and the dispersion of his fortune.

Not So Fast: A Response to Raskin

Journal of Humanistic Psychology, 2018
In our response to Raskin, we caution that combining incompatible vocabularies usually results in a linguistic muddle from which it becomes increasingly difficult to escape. Although omnibus terms such as “psychosocial” and “biopsychosocial” sound reasonable, they function merely as slogans, without any clear meaning or explanatory power.

SoS GaP Slicer: Slicing SoS Goal and PRISM Models for Change-Responsive Verification of SoS

2017 24th Asia-Pacific Software Engineering Conference (APSEC), 2017
A System-of-Systems (SoS) is a collection of systems, which consists of independent constituent systems to achieve higher-level goals. As an SoS changes constantly due to external and internal factors, dynamic reconfiguration and evolutionary development must be performed effectively.

Modulation of the SOS response by truncated RecA proteins

Molecular and General Genetics MGG, 1989
RecA protein plays several key roles in the SOS response. We have constructed truncated proteins and examined their capacity to accomplish Weigle reactivation and mutagenesis of bacteriophage lambda and recombination in Escherichia coli. Our data indicate that the 17 carboxyl terminal amino acids are not essential to RecA function.

Induction of SOS Response by Autoregulatory Factors of Microorganisms

Russian Journal of Genetics, 2003
Among examined microbial growth regulators of alkyl hydroxybenzene group (hexylresorcinol, methylresorcinol, and hydroxyethylphenol), only hexylresorcinol induces cellular SOS response, demonstrating a dose-dependent increase of the induction factor in the SOS chromotest with the Escherichia coli PQ37 strain.

Bacterial SOS response: a food safety perspective

Current Opinion in Biotechnology, 2011
The SOS response is a conserved inducible pathway in bacteria that is involved in DNA repair and restart of stalled replication forks. Activation of the SOS response can result in stress resistance and mutagenesis. In food processing facilities and during food preservation, bacteria are exposed to stresses and stimuli that potentially activate the SOS ...

SOS response as an adaptive response to DNA damage in prokaryotes

1996
Escherichia coli possesses an elaborate adaptive mechanism called the "SOS response" to cope with various types of DNA damage. More than 20 SOS genes, most of which are known to be involved in the functions that promote the survival of DNA-damaged cells, are induced by treatments that damage DNA or inhibit DNA synthesis. All the SOS genes share similar
