A modified vitrification method reduces spindle and chromosome abnormalities

Improvement of the Vitrification Method Suppressing the Disturbance of Meiotic Spindle and Chromosome Systems in Mature Oocytes

Vitrification method is widely used in oocyte cryopreservation for IVF but the birth rates are lower than that of the fresh oocyte. One of the known main reasons is structural instability of meiotic spindle and chromosome systems of mature oocyte. To get the best way for keeping competence of matured oocytes, we studied the best conditions for vitrification focused on equilibration times. The m...

Practice of Consanguinity and Unusual Cases of Inherited Familial Chromosome Abnormalities: A Case Report

We present 2 cases of likely rare event. In case 1, 3rd degree consanguineous marriage revealed inv(6) with same break points in parents who were found to be phenotypically normal. The same inv(6) being inherited in progeny but presented with low AMH (anti Mullerian hormone) and high level of FSH (follicular stimulating hormone) leading to polycystic ovarian syndrome/premature ovarian failure. ...

Epilepsy and chromosome 18 abnormalities: A review

PURPOSE To analyze the various types of epilepsy in subjects with chromosome 18 aberrations in order to define epilepsy and its main clinical, electroclinical and prognostic aspects in chromosome 18 anomalies. METHODS A careful overview of recent works concerning chromosome 18 aberrations and epilepsy has been carried out considering the major groups of chromosomal 18 aberrations, identified ...

Numerical and structural chromosome abnormalities

| Genetic instability, which includes both numerical and structural chromosomal abnormalities, is a hallmark of cancer. Whereas the structural chromosome rearrangements have received substantial attention, the role of whole-chromosome aneuploidy in cancer is much less well-understood. Here we review recent progress in understanding the roles of whole-chromosome aneuploidy in cancer, including t...
