Do cytogenetic analyses of human oocytes provide new data on non-disjunction mechanisms and the origin of trisomy 16?
In the present study, we report the finding of a considerable frequency of aneuploidy in oocytes from young donors, with the frequency of PSSC being higher than the frequency of whole-chromosome non-disjunction. In addition, we report vulnerable patterns of meiotic recombination in chromosome 16 that may be at risk of leading to a non-disjunction event. This gives new data on the susceptibility of the control population to conceive a trisomic 16 embryo.
Atorvastatin is a potential candidate for the prevention and therapy of diseases associated with insulin resistance such as type 2 diabetes mellitus and cardiovascular disease. One possible mechanism underlying the effects of atorvastatin on glucose and lipid metabolism may be to ameliorate a state of chronic inflammation.
