The biodiversity distribution patterns and their formation history in continental waters are studied based on some model groups such as Daphnia O.F. Müller (Crustacea: Cladocera). Most publications this genus concern the subgenus (Daphnia) while representatives of (Ctenodaphnia), inhabiting mainly temporary waters, poorly studied. We found a new species D. (C.) sinensis complex deserts Arabian ...

A new species of the lacertid genus Eremias Fitzinger, 1834 is described from northwest of Isfahan province, Central Iran. Two mitochondrial genes (cyt b and 12S DNA) were sequenced and analyzed as reliable molecular markers for the separation of this newly discovered species from closely related species within the genus Eremias: E. velox, E. persica, E. papenfussi, E. lalezharica, E. montana, ...

human mitochondrial dna (mtdna) is 16,569 base pairs (bp) in length, coding for 37 genes. during the course of evolution, nearly all the genes expressing ribosomal proteins and ribosomal rnas (rrna) genes have been transferred from the mitochondria to the nucleus. however, mitochondrial dna contains two ribosomal rnas genes (12s and 16s), which have not yet transferred to the nucleus. these two...

Human cysticercosis caused by Taenia crassiceps tapeworm larvae involves the muscles and subcutis mostly in immunocompromised patients and the eye in immunocompetent persons. We report a successfully treated cerebellar infection in an immunocompetent woman. We developed serologic tests, and the parasite was identified by histologic examination and 12s rDNA PCR and sequencing.

Streamflow is essential for maintaining healthy aquatic ecosystems and for supporting human water supply needs. Changes in climate, land use and water use practi...

Re-examination of the holotype of Burmoniscus kitadaitoensis Nunomura, 2009 from Kitadaitojima Island, southern Japan reveals that this species is a junior synonym of B. meeusei (Holthuis, 1947). Partial regions of mitochondrial COI, 12S and 16S rRNA genes, and nuclear 18S and 28S rRNA genes were detected for species identification in the future.

We prove that in a free group the length of the value of each variable in a minimal solution of a standard quadratic equation is bounded by 2s for orientable equation and by 12s for non-orientable equation, where s is the sum of the lengths of the coefficients.

The phylogenetic relationships among members of the Odonates were inferred from mitochondrial DNA 12S ribosomal RNA sequence data. These data show support for a monophyletic Anisoptera suborder, which are consistent with previous phylogenetic work performed on the group. However, the Zygoptera are paraphyletic based on mitochondrial DNA evidence. In particular, the family Lestidae appears more ...

Leukotriene B (LTB), a potent lipid chemotactic factor for neutrophils, is 5S,12R-dihydroxy-6,14-cis,8,10-trans-eicosatetraenoic acid (Fig 1), based upon direct comparison of natural LTB with synthetic 5S,12R-dihydroxy-6,8,10,14-eicosatetraenoic acid (5,12-di-HETE) stereoisomers in three biological assays. Of the six synthetic stereoisomers evaluated, only the 5S,12R,6,14-cis,8,10-trans compoun...
