A third fraction of O2- combines with NO, having a similar affinity to this oxygen radical as SODs, to give peroxynitrite, a source of hydroxyl and carbonate radicals as well as NO2, in other words, an additional origin of destruction and nitration of proteins [ 198] or aromates [ 168, 198].
The possibility of a role for cells of myeloid origin, such as macrophages/microglia, as an additional source of IFN- γ is controversial and has received little attention (for review on this matter see ref. 26).
Whether of ancestral or foreign origin, the duplication of resident genes serves as an additional source of genetic novelty.
As an additional advantage, the origin of the two factors of the goalkeeper-model can be deduced plausibly from the perspective of Wolbachia's evolutionary past.
As an additional investigation into the origins of these genes in eukaryotic organisms, the intron positions were examined in the eukaryotic homologs (Figure S3).
Here we utilize lead isotopes as an additional isotopic tracer to identify origins.
With both sets of breakpoints, we found associations with previously known features tRNAs, Tys, and LTRs and we also identified origins of replication as an additional element associated with genome fragility.
Recently, the epigenetic origins of cancer have been suggested as an additional mechanism giving rise to the malignant phenotype.
"Some schools asked for parents' birth certificates, for applicants country of origin, whether they were UK nationals, whether the spoke English as an additional language and if they had any medical issues," it added.
As an additional control, the IROme assay was tested on genomic DNA of a previously described family of Algerian origin, affected by LCA or early onset retinal degeneration [ 14].
