Effects of a Heated Anesthesia Breathing Circuit on Body Temperature in Anesthetized Rhesus Macaques ().

This study evaluated the effects of using a heated anesthesia breathing circuit in addition to forced-air warming on body temperature in anesthetized rhesus macaques as compared with forced-air warming alone. Hypothermia is a common perianesthetic and intraoperative complication that can increase the risk of negative outcomes. Body heat is lost through 4 mechanisms during anesthesia: radiation, conduction, convection, and evaporation.

Mid-Tibiofibular Amputation as a Method of Terminal Blood Collection in .

The African clawed frog, , is a widely used model for biomedical research. could be more useful as a model with a better method for collection and analysis of its blood and serum. However, blood collection in can be challenging due to their small size, lack of peripheral vascular access, and species-specific hematology variables.

A Yorkshire swine (Sus scrofa domesticus) model for nerve regeneration and ischemia based on the sciatic nerve and femoral artery.

Animal studies are essential to biomedical research and the cornerstone is a reproducible animal model. While there are many reports on rodent peripheral nerve injury models, a large animal model is essential to confirm the effects of nerve regeneration over the longer distances of regeneration required in humans. Swine have long been used as a large animal model for other surgical and biomedical studies.

Effect of Home Cage Bedding in the Induction Chamber on Serum Cortisol and Corticosterone Levels in Response to Isoflurane-induced Anesthesia in C57BL/6J Mice.

Mice are routinely anesthetized with isoflurane in an induction chamber. The AVMA Guidelines for the Euthanasia of Animals states that distress should be minimized during euthanasia but does not address this point in regard to induction of anesthesia. Here we evaluated the potential for familiar surroundings to reduce the adrenocortical response of mice during anesthesia induction with isoflurane.
