Development of techniques for the preservation and use of gonadal tissues are increasingly needed for the genetic management of the endangered African painted dog (). Here we evaluated two cryopreservation techniques for ovarian tissue (2 × 2 × 1 mm fragments, = 11 individuals): needle immersed vitrification (NIV), with equilibration in a 7.5% dimethyl sulfoxide (DMSO) and 7.

- The study aimed to measure plasma fentanyl concentrations, pain response, and respiratory effects following the use of transdermal fentanyl patches in ball pythons and to compare findings with turtles.
- A total of 44 ball pythons and 10 turtles were tested with varying fentanyl dosages, and significant plasma concentrations were observed without changes in pain response, suggesting an inherent resistance to the pain-relieving effects of μ-opioid receptors.
- While fentanyl application led to decreased breathing rates in ball pythons, the results showed that their response to pain relief did not improve, indicating limited efficacy of μ-opioid treatment in this species.
