"Activation of ataxia telangiectasia mutated by DNA strand break-inducing agents correlates closely with the number of DNA double strand breaks.",

AbstractThe protein kinase ataxia telangiectasia mutated (ATM) is activated when cells are exposed to ionizing radiation (IR). It has been assumed that ATM is specifically activated by the few induced DNA double strand breaks (DSBs), although little direct evidence for this assumption has been presented. DSBs constitute only a few percent of the IR-induced DNA damage, whereas the more frequent single strand DNA breaks (SSBs) and base damage account for over 98% of the overall DNA damage. It is therefore unclear whether DSBs are the only IR-induced DNA lesions that activate ATM. To test directly whether or not DSBs are responsible for ATM activation, we exposed cells to drugs and radiation that produce different numbers of DSBs and SSBs. We determined the resulting ATM activation by measuring the amount of phosphorylated Chk2 and the numbers of SSBs and DSBs in the same cells after short incubation periods. We found a strong correlation between the number of DSBs and ATM activation but no correlation with the number of SSBs. In fact, hydrogen peroxide, which, similar to IR, induces DNA damage through hydroxyl radicals but fails to induce DSBs, did not activate ATM. In contrast, we found that calicheamicin-induced strand breaks activated ATM more efficiently than IR and that ATM activation correlated with the relative DSB induction by these agents. Our data indicate that ATM is specifically activated by IR-induced DSBs, with little or no contribution from SSBs and other types of DNA damage. These findings have implications for how ATM might recognize DSBs in cells

"Building Web Ontology for Crop-Pests Domain to Allow Better Search on the Web",
INFOS2005, Faculty of Computers and Information, Cairo University , 19-22 March 2005.
AbstractOntology is the backbone of the semantic web. To apply
the semantic web concept, you should build ontology for
your domain. Building ontologies require cooperation
among domain experts to classify items in the domain,
specify properties, and determine rules for inferring new
information from the ontology. Once ontology was built,
stored in knowledge base system and published on the
web, an intelligent search engine or an inference engine
can query and make inference on this ontology. Also
ontology developers can reuse and extend this ontology. In
this paper we will show how we can build ontology for the
crop pests in the Agriculture domain, specify what the
benefits of this ontology are and how the query result is
more accurate than searching traditional web. In our
process we used the Ontology Web Language (OWL) [1]
as it is the most recent Ontology language proposed by
World Wide Web Consortium W3C (http://www.w3c.org)
and for its powerful features. Also we used protégé2000 as
Ontology Editor as it is suitable for OWL.
