Mitochondrial DNA sequence variation can be used to infer honey bee evolutionary relationships. We examined DNA sequence diversity in the cytochrome C oxidase I (COI or Cox1) gene segment of the mitochondrial genome in 112 samples of Apis mellifera from 15 different populations in Turkey. Six novel haplotypes were found for the COI gene segment. There were eight variable sites in the COI g...
Sharing information across diverse teams is increasingly important in military operations, intelligence analysis, emergency response, and multi-institutional scientific studies. Communities of Interest (COIs) are an approach by which such information sharing can be realized. Widespread adoption of COIs has been hampered by a lack of adequate methodologies and software tools to support the COI l...
آرتمیا سخت پوست کوچکی با ارزش اقتصادی بالاست که مدل تحقیقاتی بسیار مناسبی برای محققان میباشد. این موجود با تحمل محدودههای بسیار متنوع از شرایط بسیار مختلف اکولوژیک در بیش از 600 نقطه زمین و نیز 18 زیستگاه در ایران توزیع شده است. دریاچه طشک در استان فارس یکی از زیستگاه های طبیعی آرتمیای پارتنوژنز در ایران میباشد. با توجه به وجود یک آرتمیای دو جنسی ناشناخته در این دریاچه، گونه این جمعیت غیر بو...
The barcode of life project has assembled a tremendous number of mitochondrial cytochrome c oxidase I (COI) sequences. Although these sequences were gathered to develop a DNA-based system for species identification, it has been suggested that further biological inferences may also be derived from this wealth of data. Recurrent selective sweeps have been invoked as an evolutionary mechanism to e...
We aimed to examine the effect of Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA⁺-M2BP) level on survival comparing with other laboratory liver fibrosis markers in hepatitis C virus (HCV)-related compensated liver cirrhosis (LC) (n = 165). For assessing prognostic performance of continuous fibrosis markers, we adapted time-dependent receiver operating characteristics (ROC) c...
Cytochrome c oxidase I (COI) is a powerful marker for DNA barcoding of animals, with good taxonomic resolution and a large reference database. However, when used for DNA metabarcoding, estimation of taxa abundances and species detection are limited due to primer bias caused by highly variable primer binding sites across the COI gene. Therefore, we explored the ability of the 16S ribosomal DNA g...
Online learning communities are entering the realm of web-based learning as a means of reflective collaborative learning. The purpose of this article is to describe the formation of an online learning community using a community of inquiry (COI) conceptual framework. Operative clinical simulation dental students at the University of British Columbia in Canada have been involved in an online COI...
The COI gene as the core of the DNA barcoding system for animals has received significant attention. The observed wide overlap between intraand interspecific sequence variability has led researchers to envisage the primary COI-based method. The sequences of 16S rDNA, COI, and Cyt b genes of Nezara virudula (L.) (Hemiptera: Pentatomidae) from 13 countries and the same sequences of N. antennata S...
BACKGROUND There has been significant discussion about the need to manage conflict of interest (COI) in medical journals. This has lead many journals to implement policies to manage COI for authors and reviewers; however, surprisingly little attention has been focused on the COI of journal editors. OBJECTIVE The goal of this exploratory study was to determine whether the policies were accessi...
DNA-based identification system using the mitochondrial cytochrome oxidase subunit I (COI) gene has enabled validation of many species in certain taxonomic groups. These primer combinations were able to work universally across Insecta. Here, a set of three primer pairs were successful in amplifying COI of Mansonia annulata mosquito, a potential vector of Brugia malayi. By merging all three ampl...
