The major challenge for a greater dissemination of in vitro produced (IVP) bovine embryos is to improve embryonic survival after cryopreservation. The involvement of embryonic lipids on this issue is well documented. However, it has been recognized that not only the amount of lipids that affects embryo cryotolerance, but the embryo survival capacity after cryopreservation is a rather multifactorial event. In this review, some strategies to improve embryonic lipid composition and postcryopreservation survival by modifying the embryos themselves to make them more cryopreservable are overviewed. The use of semi-defined and defined serum-free culture media, the addition of some chemicals in the culture media to modify embryo lipid composition, and the modulation of embryo cell membrane fluidity by cholesterol or unsaturated fatty acids added to the culture media and oocyte/embryo donor nutritional management with a diet enriched in polyunsaturated fatty acids, were described as alternatives for the improvement of IVP embryo survival after cryopreservation.

The eletrochemotherapy is a new treatment option for neoplasms that involves the application of chemotherapeutic drugs endovenously or intralesionally, associated with local severe and short duration electrical pulses. The electrical pulses promote destabilization of the cell membrane, causing transitory pore formation and facilitating the entry of chemotherapeutic agents inside the cells, increasing its cytotoxicity. This therapy allows for lower doses of chemotherapy drugs compared to conventional chemotherapy, resulting in the decrease of side effects and costs of treatment. The eletrochemotherapy has proved effective in the treatment of cancer regardless of its histological origin and location. This review aims to highlight possibilities to use this treatment in Veterinary Oncology
