The Use of Simulators in Training for Bovine Reproductive Procedures: A Scoping...
Azuaga Filho, Heitor; Colaço, Bruno; Payan-Carreira, RitaTraining in bovine reproduction requires not only technical proficiency but also ethical responsibility and adherence to animal-welfare standards. Traditional instruction relies heavily on repeated practice in abattoir-collected specimens and live cattle, raising concerns about stress, variability, logistical constraints, and student anxiety. Simulation-based education (SBE) has therefore emerged as a pedagogic...
Exploring canine mast cell tumors: An investigation into demographic characteri...
Catarino, José; Pinello, Katia; Niza-Ribeiro, João; Santos, Joana; Payan-Carreira, Rita; Reis, Joana; Faísca, PedroMast cell tumors (MCT) are among the most common neoplasia in dogs, representing up to 21 % of skin tumors. However, etiology and risk factors for its development remain unclear. This study aimed to reduce this knowledge gap by comprehensively analyzing 905 MCT cases diagnosed in Portugal between 2019 and 2021, using descriptive and inferential analyses. Most tumors affected the skin, with 69.9 % and 21.2 % cla...
Donkey endometrium: Characterization of resident immune cells.
Radar-Chafirovitch, Ariana; Quaresma, Miguel; Yánez-Ortiz, Ivan; Leiva, Belen; Ferreria-Dias, Graça; Payan-Carreira, Rita; Miro, JordiThe Burro de Miranda is an endangered donkey breed. The dynamics of the immune system of the donkey's reproductive tract are essential to manage the fertility of these animals for the improvement and survival of the species. In mares, high numbers of immune cells infiltrating the endometrium promote endometrosis, which is still to be confirmed in jennies. Uterine biopsies of 32 jennies were evaluated based on t...
Immunocastration as Welfare Improvement in Outdoor Pig Production Systems
Botelho-Fontela, Sofia; Paixão, Gustavo; Payan-Carreira, Rita; Esteves, AlexandraRenowned for their high-quality meat from autochthonous breeds like the Iberian and Bísaro pigs, extensive pig farms prioritize animals’ welfare as a crucial factor in maintaining meat quality. In these systems, pig welfare results from the importance of providing abundant space, allowing for the full expression of the species’ behavior, and proper care. Immunocastration is a tool that might positively contribu...
Utero-placental expression and functional implications of HSD11B1 and HSD11B2 i...
Tavares Pereira, Miguel; Schuler, G.; Aslan, S; Payan-Carreira, Rita; Reichler, I.M.; Reynaud, K; Kowalewski, M.P.Apart from being stress mediators, glucocorticoids modulate the feto-maternal interface during the induction of parturition. In the dog, the prepartum rise of cortisol in the maternal circulation appears to be erratic, and information about its contribution to the prepartum luteolytic cascade is scarce. However, the local placental upregulation of glucocorticoid receptor (GR/NR3C1) at term led to the hypothesis...
Training Critical Thinking and Decision-Making Using SWOT Matrices
Payan-Carreira, Rita; Silva, Ruben; Rebelo, Hugo; Sebastião, LuisThe SWOT analysis, originally a strategic planning tool used in business, has been spread into different contexts, namely as a pedagogical approach to inculcate critical thinking skills, enabling individuals to better assess situations and make informed decisions. The SWOT matrix can be a useful tool for training informed decision-making and strengthen students critical thinking skills. Critical thinking skills...
Changes in critical thinking using a blended curriculum in a veterinary gynecol...
Payan-Carreira, Rita; Sacau, Ana; Silva, Ruben; Rebelo, Hugo; Sebastião, LuisThe Think4Jobs Project aimed to integrate critical thinking (CT) into apprenticeships and courses, focusing on assessing changes in CT skills and dispositions. In the second term of the 2022/23 academic year, in the Gynecology, Andrology, and Obstetrics course within the Veterinary Medicine Master’s Programme at the University of Évora, a CT blended curriculum was developed, engrained in case-based strategies a...
Exploring Morphometric Features of the Female Reproductive Tract in Brazilian P...
Azuaga-Filho, Heitor; Payan-Carreira, Rita; Colaço, BrunoThe cattle in the Pantanal region show a notable influence from Bos indicus breeds and their crossbreeds. However, a comprehensive biometric assessment of the reproductive system in these animals is currently lacking. This study evaluated the effects of breed, age, carcass weight, and estrous cycle phase on female reproductive system morphometry. A total of 124 healthy, non-pregnant reproductive tracts (83 Nelo...
Antioxidant enzyme dynamics suggest the absence of oxidative stress in the cani...
Payan-Carreira, Rita; Santos, Celso; Santos, DarioOxidative stress plays a vital role in female fertility, yet the mechanisms regulating oxidative balance in the canine endometrium remain poorly understood. This study investigates the dynamics of the antioxidant enzyme system in the canine endometrium, focusing on superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GSR), and glutathione-S-transferase (GST), along wi...
Development of a New Simulator for Training Nelore Artificial Insemination
Azuaga Filho, Heitor; Colaço, Bruno; Payan-Carreira, RitaBackground Regular training is crucial for student and novice operators conducting artificial insemination to ensure successful cattle reproduction. Standardized repetitions help generate autonomy and self-confidence. It is also essential for proficiency in the technique, assuring consistency and success in the procedure. Training live animals for AI procedures raises ethical concerns and requires a regular sup...
