During a presentation at the 2016 ASCO Annual Meeting in Chicago, Illinois, a bioethicist joked that financial conflict of interest (COI) disclosures were the great success of modern bioethics. I appreciated the irony; perhaps our focus on financial COI has overshadowed other competing interests at the intersection of academic medicine and clinical research. Nonfinancial COIs may be equally per...

Although much biological research depends upon species diagnoses, taxonomic expertise is collapsing. We are convinced that the sole prospect for a sustainable identification capability lies in the construction of systems that employ DNA sequences as taxon ‘barcodes’. It was established previously that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioident...

Bactrocera (Bactrocera) kohkongiae Leblanc (Diptera: Tephritidae: Dacinae), from the Koh Kong Province of Cambodia, is described as new. This species belongs to the Oriental fruit fly (B. dorsalis) complex. Genetic sequences (mitochondrial COI and nuclear EF1α and Period) are deposited in GenBank. A haplotype network, based on the COI sequences for 21 specimens, shows high genetic diversity. Ne...

The 72 hour chick embryo heiirt reacts to progressive hypoxia by the appearance of arrhythmias and asystole. In the presence of 4 per cent COi, complete auoxia is tolerated for a period of 30 min. with carbon dioxide apparently augmenting the buffering capacity of the plasma clot which supports the heart. A gaseous environment of 4 per cent OJ/4 per cent COi/92 per cent X. induced a steady and ...

We describe "universal" DNA primers for polymerase chain reaction (PCR) amplification of a 710-bp fragment of the mitochondrial cytochrome c oxidase subunit I gene (COI) from 11 invertebrate phyla: Echinodermata, Mollusca, Annelida, Pogonophora, Arthropoda, Nemertinea, Echiura, Sipuncula, Platyhelminthes, Tardigrada, and Coelenterata, as well as the putative phylum Vestimentifera. Preliminary c...

Channa punctatus is a freshwater fish belonging to family Ophiocephalidae. This fish is available in almost all over the country. In present communication molecular study of COI region of mitochondrial gene was done to find out intraspecific differences in genome of Channa punctatus habitating in different states of India having variable environmental conditions. Result showed minor variations ...

The intermediate hosts of Schistosoma mansoni, in Brazil, Biomphalaria glabrata, B. tenagophila and B. straminea, were identified by restriction fragment length polymorphism analysis of the mitochondrial gene cytochrome oxidase I (COI). We performed digestions with two enzymes (AluI and RsaI), previously selected, based on sequences available in Genbank. The profiles obtained with RsaI showed t...

To elucidate the Anopheles nuneztovari s.l. taxonomic status at a microgeographic level in four malaria endemic localities from Antioquia and Córdoba, Colombia, fragments of the cytochrome oxidase subunit I (COI) and the white gene were used. The COI analysis showed low genetic differentiation with fixation index (F(ST)) levels between -0.02-0.137 and Nm values between 3-∞, indicating the prese...
