Triatoma rubrofasciata (De Geer) is the first species of triatomine described, and little is known on its vector biology. Studies are restricted to starvation resistance, interspecific morphometric variability, morphometry of testis follicles, coloration of the testicular peritoneal sheath, ultrastructure of the male accessory glands, phylogeny and cytogenetics. Thus, this study aims to address...

The genus Mesoplodon (Cetacea: Odontoceti: Ziphiidae) is one of the few cetacean genera with the karyotype 2n = 42. The 2n = 42 karyotype of M. europaeus and M. carlhubbsi is largely consistent with the general cetacean karyotype 2n = 44, although other 2n = 42 karyotypes do not exhibit clear homologies with the general cetacean karyotype. Therefore, the chromosomes of Mesoplodon species may be...

STUDY QUESTION Do women with Turner karyotype have increased mortality and morbidity in the years after childbirth? SUMMARY ANSWER No mortality occurred during pregnancy and follow-up in women with Turner karyotype, but a higher rate of circulatory and endocrine diseases and a high risk of aortic aneurysm were confirmed. WHAT IS KNOWN ALREADY Pregnancies in women with Turner karyotype are h...

the autism spectrum disorders (asds) are common neurodevelopmental disorders estimated to affect 1 in 88 children. asd is a complex condition, result of genetic, epigenetic and environmental factors. however, genetic comopnent seems to play an important role. the loss/gain of 1kb and more nucleotides, copy number variation (cnv), is the significant genetic factor in the etiology of asd. the cnv...

background: carriers of translocations may have an increased risk of an unbalanced progeny due to imbalances and delays in meiosis. case: a 24-year-old pregnant iranian female was referred to the genetic department of yazd clinical and research centre for infertility because of her pregnancy history. she had three previous pregnancies, two of which ended in abortion. the one live born infant wa...

Background & Aims: Induced pluripotent stem cells (iPSCs) have the capability to undergo unlimited selfrenewal and differentiation into all cell types in the body. These cells are artificially derived from a nonpluripotent cell, typically human dermal fibroblasts (HDFs). The study of cytogenetic stability of these cells, in order to use iPS cells and apply studies in therapeutic applications, i...

the aim of this study is to investigate the relationship between dividend policy with stock liquidity and information asymmetry considering the characteristics of the company as controlling variables in tehran stock exchange. for this purpose, all listed companies in tehran stock exchange as the statistical population was considered during the period 2009 to 2014, that after screening by simple...

A 45,X karyotype is one of the common chromosomal abnormalities characterized by short stature, lack of development of secondary sexual characteristics, webbed neck and cubitus valgus. This phenotype was described by Turner in 1938 and was called Turner syndrome (TS). About 40-60% of the patients with TS phenotype have a 45,X karyotype, the rest either have a structurally abnormal X or Y chromo...

In order to investigate the influence of the molecular karyotype based on single nucleotide polymorphism (SNP) microarray on embryonic development potential in preimplantation genetic diagnosis (PGD), we retrospectively analyzed the clinical data generated by PGD using embryos retrieved from parents with chromosome rearrangements in our center. In total, 929 embryos from 119 couples had exact d...
