Gene Ontology (GO) has been developed to provide concepts for the functional annotation of biological entities. This development has already contributed to significant biomedical research results. Nonetheless, GO could have provided even stronger support to biomedical text mining, if it delivered domain-independent logical definitions of its concepts. We present a method that extracts the seman...

A model of major ejection events in Galactic superluminal sources GRO J 1655-40 and GRS 1915-105 is proposed, in which episodes of e−e+ pair creation give rise to the formation of optically thick outflows accelerating protons to the limiting Lorentz factor of order 2-3. Probable source of e−e+ pairs is pion production in nucleon collisions. Subsequent deceleration of ejecta and formation of rad...

A rhenium-oxo complex such as methyltrioxorhenium (MTO) has been homogeneously immobilized on a Schiff base modified graphene oxide (GrO) support via covalent bonding. The loading of MTO on GrO nanosheets was monitored by FTIR, TG-DTA, and elemental analyses. The developed heterogeneous catalyst is found to be efficient for the oxidation of various amines to the corresponding N-oxides using hyd...

Semantic querying over the biomedical literature has gained popularity, where a semantic representation of biomedical documents is required. Previous BioNLP Shared Tasks exercised semantic event extraction with a small number of pre-defined event concepts. The GRO task of the BioNLP’13-ST imposes the challenge of dealing with over 100 GRO concepts. Its annotated corpus consists of 300 MEDLINE a...

Interleukin-8 (IL-8) and the structurally related cytokines neutrophil-activating peptide-2 (NAP-2) and GRO alpha are powerful chemotactic agents for human neutrophils. Although these three chemokines act by binding to overlapping but not identical receptor subsets, the data available to date have stressed the similarities in their mechanisms of action. The present studies were undertaken to fu...
