Repair of a Large Ventral Hernia in a Rhesus Macaque (Macaca mulatta) by Using an Abdominal Compo...
Here we present a 32-y-old rhesus macaque (Macaca mulatta) with a large recurrent ventral incisional hernia. The initial surgery included midline celiotomy for treatment of endometriosis, in which the animal developed a hernia that was repaired with in...
Methods for Investigating the Motivation of Mice to Explore and Access Food Rewards
Methods for Investigating the Motivation of Mice to Explore and Access Food Rewards
The emotional state of domestic animals is an essential component of the assessment of their welfare. In addition, sensitivity to various rewards can be a valuable indicator when investigating these states.
Animal Models of Aspergillosis
Animal Models of Aspergillosis
Aspergillosis is an airborne fungal disease caused by Aspergillus spp., a group of ubiquitous molds. This disease causes high morbidity and mortality in both humans and animals.

To protect the biosecurity of research rodent colonies, research institutions frequently require a quarantine period for live animals transferred into their facilities. Quarantine practices often include antibiotic and antiparasitic treatment with drug...
Systemic Iron Deficiency in a Nonhuman Primate Model of Endometriosis
Systemic Iron Deficiency in a Nonhuman Primate Model of Endometriosis
Endometriosis is characterized by endometrial tissue development outside the uterus. Anemia and iron depletion do not commonly accompany endometriosis in women, despite chronic abdominal inflammation and heavy menstrual bleeding.

Analgesic Efficacy of Subcutaneous´┐ŻOral Dosage of Tramadol after Surgery in C57BL/6J Mice
This study investigated the analgesic activity of tramadol in female C57BL/6J mice by using a single subcutaneous injection (25 mg/kg) of tramadol combined with the same dose given in drinking water for 24 h. We then evaluated the pharmacokinetics of t...
Out Like a Light? The Effects of a Diurnal Husbandry Schedule on Mouse Sleep and Behavior
Out Like a Light? The Effects of a Diurnal Husbandry Schedule on Mouse Sleep and Behavior
Sleep disruption in humans, caused by shift work, can be detrimental to physical and behavioral health. Nocturnal laboratory mice may experience a similar disruption caused by human daytime activities, but whether this disruption affects their welfare ...
Reproductive Performance after Unilateral or Bilateral Oviduct Transfer of 2-Cell Embryos in Mice
Reproductive Performance after Unilateral or Bilateral Oviduct Transfer of 2-Cell Embryos in Mice
Embryo transfer (ET) is a frequent procedure in contemporary animal and transgenic facilities. We compared the reproductive performance of mice after unilateral and bilateral ET of 15 to 18 two-cell embryos per recipient.
