Correspondence: [email protected] Department of Oncological Sciences, Icahn School of Medicine at Mount Sinai , One Gustave L. Levy place, New York, 10029, USA Full list of author information is available at the end of the article Abstract Eukaryotic cells carry two genomes, nuclear (nDNA) and mitochondrial (mtDNA), which are ostensibly decoupled in their replication, segregation and inherita...
Geographic surveys of allozymes, microsatellites, nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) have detected several genetic subdivisions among European anchovy populations. However, these studies have been limited in their power to detect some aspects of population structure by the use of a single or a few molecular markers, or by limited geographic sampling. We use a multi-marker approach...
The study of processes driving diversification requires a fully sampled and well resolved phylogeny, although a lack of phylogenetic markers remains a limitation for many non-model groups. Multilocus approaches to the study of recent diversification provide a powerful means to study the evolutionary process, but their application remains restricted because multiple unlinked loci with suitable v...
Förster resonance energy transfer (FRET) is a nonradiative process for the transfer of energy from an optically excited donor molecule (D) to an acceptor molecule (A) in the ground state. The underlying theory predicting the dependence of the FRET efficiency on the sixth power of the distance between D and A has stood the test of time. In contrast, a comprehensive kinetic-based theory developed...
میتوکندری ها در تمام یوکاریوت ها وجود دارند و برای بقاء ضروری هستند. وظیفه اولیه آنها پشتیبانی از تنفس هوازی و فراهم کردن انرژی لازم برای مسیرهای متابولیکی است. به دلیل نقش اساسی میتوکندری ها در بدن انسان هر گونه نقص در فعالیت میتوکندری می تواند پیامدهای وخیمی را به همراه داشته باشد. نقص های متابولیسم میتوکندریایی باعث طیف وسیعی از بیماری های انسانی می شود. بیماری های میتوکندریایی می توانند ناش...
mitochondria are membrane-enclosed organelle found in most eukaryotic cells, which known as power house in cells. this organelle transforms energy into forms that are usable by the cell. the most common psychiatric disorders such as depression and anxiety can be linked to mitochondrial disorders. furthermore, mutations of mitochondrial or nuclear dna (mtdna and ndna, respectively) have been lin...
The results of morphological and genetic analyses forms/species the Coregonus lavaretus pidschian (Gmelin, 1789) complex from Indigirka Kolyma river basins are presented in context there being recent postglacial speciation events. It has been found that studied whitefishes belong to sparsely rakered low lateral-line forms have previously described as n. jucagiricus Drjagin (Berg), 1932. Based o...
Gaidropsarus Rafinesque, 1810 is a genus of marine teleost characterized by high ecological diversity and species inhabiting from the intertidal zone to deep-sea. Several taxonomic conundrums have been historically present in this taxon due its conservative morphology lack available specimens. Species delimitation analyses were carried out multiple datasets combining both mitochondrial (COI, Cy...
abstract bachground and aim: mutation analysis of mitochondrial genome and brca genes are helpful in the early diagnosis of familial breast cancers. in this study, we investigated mitochondrial common deletion and brca mutations through multiplex pcr and clinical parameters for the detection of familial breast cancers in archival breast cancer samples. methods: the multiplex pcr was conducted o...
