A massive open online course (MOOC) in canine theriogenology was offered for dog owners and breeders and for veterinary professionals as a partnership between the University of Minnesota and Coursera. The six-week course was composed of short video lectures, multiple-choice quizzes with instant feedback to assess understanding, weekly case studies with peer evaluation to promote integration of course materials, and discussion forums to promote participant interaction. Peak enrollment was 8,796 students. The grading policy for completion was strict and was upheld; completion rate for all participants was 7.5%. About 12% of participants achieved a grade of over 90% in the course, with those who had any deficiency mostly missing one quiz or assignment. Ninety-nine individuals were enrolled in a for-cost, credentialed pathway, and 50% of those individuals completed all required course components. Pre- and postcourse surveys were used to demonstrate that learning objectives were met by the participants and to identify that lack of time to commit to study was the biggest impediment to completion. Positive aspects of the course were active engagement by participants from all over the world and the ability of this university and instructor to reach those learners. Negative aspects concerned technical support and negative feedback from some participants who were unable to meet course requirements for reasons beyond the control of the instructor.

Ultrasonographic computer-assisted quantification of the intraluminal uterine content in female dogs.

In dogs, the characterization of intraluminal uterine contents has been subjectively carried out by the operators. The aims of this study were: 1) To ultrasonographically describe and compare the echogenicity and heterogeneity of the intraluminal uterine contents in bitches using digital analysis; 2) To assess the cytology of the uterine contents; 3) To evaluate the effect of clinical, ultrasonographic, bacteriological and cytological parameters on intraluminal contents echogenicity and heterogeneity. Twenty-one intact, 3-24 kg, 1-12 years of age, female dogs with ultrasonographically detected uterine content were included.

Understanding the molecular characteristics and metabolic processes of the mammalian endometrium is crucial for advancing biological research, particularly in veterinary obstetrics and pathology. This study established and analyzed organoids from the endometrial epithelial stem cells of five mammals with different placental types: cows (cotyledonary), dogs and cats (zonary), pigs (diffuse), and rats (discoid). The organoids from these five species were maintained for over 13 passages, successfully frozen-thawed, and confirmed by pathological analysis to retain the characteristics of the original tissues.

Article Synopsis
- - The study focused on evaluating the uterine artery resistivity index (RI) through Doppler ultrasonography to assess canine fetal and placental conditions during pregnancy, particularly in relation to embryo resorption rates.
- - It examined 44 bitches of varying breeds and weights, conducting ultrasounds 25 days post-ovulation to gather data on embryo viability and resorption sites, along with factors like age and size group.
- - Statistical analysis revealed a significant relationship between the RI and gestational age and the percentage of embryo resorptions, indicating that these factors may influence uterine blood flow in pregnant dogs.

Importance: The intravenous administration of adipose tissue-derived mesenchymal stem cells (AdMSCs) in veterinary medicine is a promising regenerative therapy, but it can lead to severe complications, including pulmonary thromboembolism (PTE).
Objective: As part of an ongoing study, this study examined the impact of medications, such as heparin, aspirin, and sodium nitroprusside (SNP), on the factors linked to PTE after an intravenous injection of canine mesenchymal stem cell into experimental animals.
Methods: Fluorescently labeled canine AdMSCs were administered intravenously into the tail veins of five-week-old male BALB/c hairless mice.

Companion animals, such as dogs and cats, have gained considerable attention in translational medicine due to their potential as models for human diseases. The use of these animals in research has opened new avenues for developing treatments that can benefit both human and veterinary patients, aligning with the One Health approach. Unlike traditional laboratory models like mice, rats, and rabbits, companion animals naturally develop diseases that closely mirror those in humans, including but not limited to diabetes, aging, cancer, and neurological disorders, making them particularly valuable in translational research.
