In the context of musical analysis, we propose an algorithm that automatically induces patterns from polyphonies. We define patterns as “perceptible repetitions in a musical piece”. The algorithm that measures the repetitions relies on some general perceptive notions: it is non-linear, non-symetric and non-transitive. The model can analyse any music of any genre that contains a beat. The analys...

Cytogenetic abnormalities are frequently detected in patients with acute lymphoblastic leukemia (ALL). Comprehensive karyotype was related to poor prognosis frequently in ALL. We present a comprehensive karyotype in an adult ALL by spectral karyotyping (SKY) and R-banding. SKY not only confirmed the abnormalities previously seen by R-banding but also improved comprehensive karyotype analysis wit...

Background: Karyotype analysis has been the standard and reliable procedure for prenatal cytogenetic diagnosis since the 1970s. However, the major limitation remains requirement for cell culture, resulting in a delay of as much as 14 days to get the test results.CGH array technology has proven to be useful in detecting causative genomic imbalances or genetic mutations in as many as 15% of child...

OBJECTIVE To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype. DATA SOURCES Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on. DATA SYNTHESIS Congenital ...

Objective To compare the roles of fluorescence in situ hybridization (FISH) and karyotype analysis on chorionic villus in spontaneous abortion. Methods A total of 201 cases were included in this study and were randomly divided into 2 groups by the same gestational age. The villi from 100 cases (group A) were cultured and used for karyotype analysis, while the uncultured villi from 101 women (gr...

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...

In acute myeloid leukemia, the karyotype of the leukemic cell is the most powerful predictor of treatment outcome. Approximately 30% of cases of AML have an unfavorable karyotype, and if treated with conventional chemotherapy, a complete response rate of about 50% and a 5-year overall survival of 10% to 20% are expected. Of those in the unfavorable group, almost half will have a complex karyoty...

Mixed phenotype acute leukemia (MPAL) is a complex entity expressing both lymphoid and myeloid immunophenotyping. In the present study, 47 MPAL, 60 lymphoid antigen-positive acute myeloid leukemia (Ly(+)AML), and 90 acute myeloid leukemia with common myeloid immunophenotype (Ly(-)AML) patients were investigated. We found that, in MPAL patients, there were high proportions of blast cells in bone...

In this case report we present a child with an additional chromosome in the karyotype. The karyotypes of the boy and his parents were analyzed by use of a conventional banding technique (GTG) and fluorescence in situ hybridization (FISH). Probes painting whole chromosomes 12 and 18 were used in FISH. Cytogenetic examination of the parents revealed that his mother was carrying balanced reciproca...
