Investigating sperm cryopreservation in a model tunicate, Ciona intestinalis sp. A.

In cryopreservation procedures, the capacity to protect the cells from freezing and thawing processes is sensitive to the choice of the cryoprotective agent (CPA) and to its optimal concentration. The advancement of research on Tunicate model species has raised interest in liquid nitrogen cryopreservation for the storage and distribution of genetic resources. Ciona intestinalis (Linnè, 1767) consists of a complex of cryptic taxa that are central to several areas of investigation, from comparative genomics to invasive biology.

Primary ovarian leiomyosarcoma as a new component in the nevoid basal cell carcinoma syndrome: a case report.

The case of primary leiomyosarcoma of the ovary in a 20-year-old Italian woman with nevoid basal cell carcinoma syndrome (NBCC) is described. This report first shows the association of ovarian leiomyosarcoma with NBCC, expanding the complex nature of this syndrome.
