Evolution and mechanism of the mitochondrial cox1 intron horizontal transfer in Angiosperms
(Canadian Society of Plant Biologists, 2017)
The most frequent case of horizontal gene transfer in angiosperms involves the group I intron in the cox1 mitochondrial gene, originally acquired from a fungal donor and followed by more than 100 subsequent inferred ...
Physico-chemical parameter correlations in the [RuCl2(CO)(L)(PPh3)2] complexes (L = N-heterocycles)
(1998-12-01)
Fourteen complexes in the series [RuCl2(CO)(L)(PPh3)2] (where L = N-heterocycles) have been prepared and characterized by IR and NMR spectroscopies, and cyclic voltammetry. A good correlation is found between observed and ...

Ultrastructural characterisation of young and aged dental enamel by atomic force microscopy
(2022)
Recent advances in atomic force microscopy (AFM) have allowed the characterisation of dental-associated biomaterials and biological surfaces with high resolution. In this context, the topography of dental enamel - the ...
Voltammetric study of the redox chemistry of 2,3-dihydroxy-quinoxaline and its zinc complexes in non-aqueous medium
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
The electrochemical behaviours of 2,3-dihydroxy-quinoxaline (2,3-DH(2)Qx) and the complex species formed with zinc(II) have been studied in non-aqueous media. Using dimethylsulphoxide or N,N-dimethylformamide as solvents ...
