Misgurnus anguillicaudatus has several natural ploidy types. To investigate whether nuclear polyploidy have an impact on mitochondrial DNA (mtDNA), the complete mitochondrial genomes (mitogenomes) of five distinct ploidy M. anguillicaudatus (natural diploid, triploid, tetraploid, pentaploid and hexaploid), which were collected in central China, were sequenced and analyzed. The five mitogenomes ...

results using these two sets, we identified h1069q mutation in four patients, c.2335t > g mutation in three, c.3061-1g > a splice site mutation in five, c.3305t > c mutation in one, and c.3809a > g mutation in two patients. conclusions the multiplex arms assay used in this study can be an efficient, reliable, and cost effective method as a primary screen for patients with wilson disease. patien...

quinolones are a large and widely consumed class of synthetic drugs. expanded-spectrum quinolones, like ciprofloxacin are highly effective against gram-negative bacteria, especially escherichia coli. in e. coli the major target for quinolones is dna gyrase. this enzyme is composed of two subunits, gyra and gyrb encoding by gyra and gyrb, respectively. mutations in either of these genes cause qu...

background: iran has a large group of patients with severe congenital factor xiii deficiency (fxiiid) and trp187arg mutation that is most disease causing mutation of fxiii in the world is only observed in southeast of iran with 352 patients with fxiiid. 743 patients with fxiiid was observed in 17 provinces of iran but tehran city with more than 12 million population has no any registered patien...

background: non-dystrophic myotonias are a heterogeneous set of skeletal, muscular channelopathies, which have been associated with point mutations within sodium channel α-subunit (scn4a) gene. because exons 22 and 24 of scn4a gene are recognized as hot spots for this disease, the purpose of the study is to identify mutation in exons 22 and 24 of scn4a gene in iranian non-dystrophic myotonias p...

Abstract Background Von Willebrand disease (VWD) is an autosomal recessive congenital bleeding disorder with deficiency or dysfunction of von Willebrand factor (VWF). The gene encoding for the VWF is located on chromosome 12, which is 178 Kb with 52 exons. Various mutations of this gene is responsible for the clinical features of VWD, but some single nucleotide polymorphisms make the molecu...
