conclusions the most effected parts in asd are lateral connections of hmasd. two-sided connections which are completely symmetric become more active, and cause extra synchronization. on the other hand, due to special characteristic of two-sided connections and their ability to simulate the same phased dynamics, they cause unnatural asymmetry in children’s eeg signal. these results are consisten...

BACKGROUND We previously found that a normal karyotype in a previous miscarriage is a predictor of subsequent miscarriage. However, the prevalence of recurrent miscarriage caused by an abnormal embryonic karyotype has not yet been reported, since embryonic karyotype is not typically analyzed during conventional examinations. METHODS A total of 482 patients who underwent both embryonic karyoty...

background : turner syndrome (ts) is a sporadic disorder caused by the absence of all or some parts one x-chromosome with major developmental consequences such as short stature and ovarian failure etc. the minor manifestations of ts are cubitus valgus, micrognatism, high-arched palate, short and/or webbed neck, hypothyroidism, etc. different karyotype abnormalities may lead to different clinica...

Information asymmetry in stock market can increase the risk of investment which in turn increases the capital cost of firms. Bhattacharya (1979) proposed a hypothesis that states dividend can act as a powerful signal in order to solve information asymmetry problem. We measured information asymmetry by lack of earnings transparency. Therefore we examine the effect of earnings transparency on cap...

the karyotype of zagros tooth-carp, aphanius vladykovi (coad) has been investigated byexamining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. the diploidchromosome number of this species was 2n=48. the karyotype consisted of 8 submetacentric and 40subtelocentric chromosomes (8sm+40 st). the arm number (nf) was 28. sex chromosomes werecytologically indistinguishab...

Placental mesenchymal dysplasia (PMD) is a rare benign placental abnormality. It is characterized by hydropic degeneration of stem villi, placentomegaly, and increased maternal serum alpha-fetoprotein(AFP). It can be associated with different congenital abnormalities, karyotype abnormalities, and feto-maternal morbidities. It is difficult to differentiate PMDfrom partial mole, complete mole wit...

introduction: most of the hematologic malignancies are heterogenous with regard to morphology, immunophenotype, and genetic rearrangements. multiple recurrent chromosomal aberrations have been identified by conventional cytogenetic analysis, which is now widely recognized as one of the most important diagnostic and prognostic determinants in these patients. patients and methods: bone marrow sam...

In this study, for the first time in Iran, the karyotype of bigmouth Lotak, Cyprinion macrostomum Heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from Godarkhosh River in Ilam Province. To stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (PHA). The cell divisions we...
