The European anchovy, Engraulis encrasicolus, is currently one of the principal target species for commercial fisheries in Europe. In this study, the mitochondrial Control Region (CR) and the Cytochrome Oxidase I (COI) mitochondrial gene were analyzed in 74 specimens of E. encrasicolus from four localities in the central Mediterranean. In both populations, the two markers revealed the presence ...

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'. We establish that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioidentification system ...

Communities of interest (COI) have been applied in a variety of environments ranging from characterizing the online buying behavior of individuals to detecting fraud in telephone networks. The common thread among these applications is that the historical COI of an individual can be used to predict future behavior as well as the behavior of other members of the COI. It would clearly be beneficia...

The population structure of the Chinese carmine spider mite Tetranychus cinnabarinus (Boisduval) was investigated by amplifying and sequencing a portion of the mitochondrial DNA gene coding for cytochrome oxidase I (COI, 453bp) and a portion in the second internal transcribed spacer (ITS2, ̃645bp) of rDNA. Nineteen T. cinnabarinus populations of various geographical origins were sampled from al...

BACKGROUND Previous studies have found associations between mitochondrial DNA (mtDNA) mutations and several cancer types. Recently, we found that mutations in the mtDNA gene cytochrome c oxidase subunit 1 (COI) were both linked to and associated with prostate cancer (PCa) in Caucasian men. Here we examine the association between COI mutations and PCa in African American men. METHODS The entir...

BACKGROUND Best practices for conflict-of-interest (COI) policies in medical schools have evolved rapidly over the past decade, in part motivated by the American Medical Student Association (AMSA) scorecard that has publicly graded schools since 2007. This report describes the methodological update and impact of revisions to the scorecard in 2014. METHODS The original AMSA scorecard (used ann...

Throughout the year, I receive questions from our Editorial Board members, reviewers, and authors about conflict of interest (COI) and disclosure—what it means, how comprehensive it should be, and how it impacts the validity of a study. Concerns arise on many fronts, from the impartiality (or lack thereof) of authors who submit a study about a product in which they are somehow invested to the r...

Conflict of interest (COI) affects every aspect of medicine, including clinical care, teaching, and research. According to one definition, “A conflict of interest exists when professional judgment concerning a primary interest (such as patients' welfare or the validity of research) may be influenced by a secondary interest (such as financial gain). Perceptions of conflict of interest are as imp...

b a ckground: anoph eles fluviatilis , one of the major malaria vectors in iran, is assumed to be a complex of sibling species. the aim of this study was to evaluate cytochrome oxidase i (coi) gene alongside 28s-d3 as a diagnostic tool for identification of an. fluviatilis sibling species in iran. m e t hods: dna sample belonging to 24 an. fluviatilis mosquitoes from different geographical area...
