We have studied partially edited molecules for the cytochrome-c oxidase subunit III (COIII) transcript from two species of the insect trypanosome Herpetomonas. We found unexpected patterns of editing, in which editing does not proceed strictly 3' to 5', in 24 of 61 partially edited clones. A comparison of the partially edited molecules between the two kinetoplastid species revealed an 8- to 10-...

A cobalt salen pentenoate complex [salen=(R,R)-N,N?-bis(3,5-di-tertbutylsalicylidene)-1,2-cyclohexanediamine] is rationally designed as the catalyst for ring-opening copolymerization (ROCOP) of epoxides/anhydrides/CO2. Via migratory insertion carbon monoxide (CO) into Co?O bonds, ROCOP-active species ?-alkene-?-O-CoIII(salen) can be rapidly and quantitatively transformed ?-alkene-?-O2C-CoIII(sa...

Background With some exceptions, mitochondria within the class Insecta have the same gene content, and generally, a similar gene order allowing the proposal of an ancestral gene order. The principal exceptions are several orders within the Hemipteroid assemblage including the order Thysanoptera, a sister group of the order Hemiptera. Within the Hemiptera, there are available a number of complet...

Complex wastewater with massive components is now a serious environmental issue facing humanity. Selective removal of low-concentration contaminants in mixed constituents holds great promise for increasing water supplies. Bioenzymes like horseradish peroxidase exhibit oxidizing power and selectivity. Here, we manufactured its mimic through immobilizing non-heme oxamate anionic cobalt(III) compl...

The coastal octopus at Saint Paul and Amsterdam Islands is Octopus vulgaris Cuvier 1797. Meristic and morphological characters, along with phylogenetic analysis of COI and COIII DNA sequences, were used to identify 11 animals collected in 2000 or 2001. The range of the species is therefore expanded to include the oceanic islands of the central southern Indian Ocean. The trees also depicted the ...
