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...
To evaluate the prognostic impact of monosomal karyotype on post-remission outcome in acute myeloid leukemia, we retrospectively analyzed 2,099 patients who had achieved complete remission. Monosomal karyotype was noted in 73 patients (4%). Of these, the probability of overall survival from first complete remission was 14% at four years, which was significantly lower than that reported in patie...
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 clinical...
The chromosomal spread and karyotype of Anjak (Schizocypris altidorsalis) from Hamoun Lake were determined using tissue squashing techniques with an injection of 1 mL/100 g body weight of 0.01% colchicines solution. Kidney and gill epithelia tissues were removed and used for karyotype analysis. The analysis of 145 chromosome spreads revealed the diploid chromosome number of this fish, 2n=48 and...
background and objective: pregnancy termination and recurrent abortion are one of the common complications during pregnancy and in patients with a bad obstetric history. materials and methods: in this study, a total of 154 individuals including 75 couples four single women from different communities and with various incomes were investigated chromosomal abnormalities using blood culture and chr...
genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. the present research focused on the cytological studies of embryogenic (e) and non-embryogenic (ne) callus as well as root meristem cells of in vitro and in vivo grown plants. on the contrary to the previous studies, a diploid viciifolia variety with 2n= 2x= 16 chromosomes was observed for...
the laboratory mouse is recognized as the pre-eminent model for genetic research. awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. we aimed to study mitotic chromosome preparations from nih, c57bl/6 and razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. bone marrow cells we...
خصوصیات کاریوتیپی چهار گونه گون (astragalus) با نامهای a. cornu-carpae ، a. mucronifoliusو a. talimansurensis از بخشه leucocersis و گونه a. crysostachysاز بخشه hymenostegis. مطالعه شدند. گونه ها وجود 2n = 2x = 16 را نشان دادند که تمامی گزارش جدید می باشند. کروموزومها از نوع متا و ساب متا بودند و اندازه آنها ازmm 75/. در a. talimansurensis تا 4 mm در a. cornu-carpaeمتغیر بود. گونه های ...
