Centrosome Abnormalities and Polyploidy in Murine Mammary Carcinomas with Different Degrees of Hormone Responsiveness.

Centrosome amplification leads to aberrant mitosis, giving rise to aneuploidy and it has been associated with poor prognosis in human cancers. This study aimed to evaluate the relationship between polyploidy, centrosome abnormalities, and response to endocrine treatment in progestin-induced mouse mammary carcinomas. We found cells with three or more centrosomes in the polyploid tumors.

First custom next-generation sequencing infertility panel in Latin America: design and first results.

Objective: To present the development of the first custom gene panel for the diagnosis of male and female infertility in Latin America.

Methods: We developed a next-generation sequencing (NGS) panel that assesses genes associated with infertility. The panel targeted exons and their flanking regions.

Effect of sperm DNA fragmentation on embryo development: clinical and biological aspects.

Objective: The aim of this study was to investigate the effect of sperm DNA fragmentation on fertilization rate, embryo development (blastulation rate), and pregnancy outcomes for ICSI cycles performed in a cohort of couples using donor eggs and to assess the remaining embryos that were not transferred or frozen for apoptotic markers.

Methods: Eighty-two women (egg recipients) were included in the study (2016) were included in the study. The recipients' mean age was 41.
