The present study aimed to develop a minimally invasive technique by employing a cytobrush for collecting endometrial cell samples retrieved from cattle and buffalo and to establish and characterize the cells. The study was divided into two experiments. Experiment I evaluated the tissue invasiveness associated with different brush cytology rotations for 3, 5, 7, and 9 rounds compared with biopsy samples. In total, 30 areas of endometrial tissue samples from the uteri of six fresh, healthy, non-pregnant bovines from a slaughterhouse were examined histologically to determine tissue invasiveness based on the perpetual endometrial layer. The seven rounds of cytobrush rotation provided optimal results with detached epithelial cell lining and sloughed-off basement membrane while maintaining intact endometrial stroma, suggesting its suitability for subsequent cell culture. In Experiment II, primary endometrial cell cultures were established employing the 7-round brush cytology method from ten healthy, Holstein Friesian and swamp buffalo cows (n = 5, each). Endometrial cells were subcultured up to the third passage for further validation. Physical characterization utilized immunocytochemistry with pan-cytokeratin and vimentin co-staining. The cultured cells were functionally assessed by quantifying prostaglandin F2 alpha (PGF2α) secretion following 0 and 100 nM oxytocin challenge. Our findings showed that cytobrush sampling yielded sufficient seeding cells for culture. The proportions of endometrial epithelial cells relative to the stromal cells at passage 3 were 89.98 ± 7.21 % and 85.18 ± 2.66 % for cows and buffaloes, respectively. The secretion of PGF2α at 24 h increased significantly in bovine endometrial cell culture with 100 nM oxytocin (931.37 ± 292.69 pg/mL) compared with 0 nM oxytocin (194.06 ± 43.95 pg/mL; <em>p</em> = 0.026), as well as in bubaline endometrial cell culture, at 100 nM oxytocin (5.17 ± 1.54 pg/mL) compared 0 nM oxytocin (1.92 ± 0.76 pg/mL; <em>p</em> &gt; 0.05).

The SIAC (Information System for Companion Animals) registry now provides a robust dataset for analyzing dog demographics in Portugal. This study examines SIAC data (2004–2023), analyzing breed, sex, reproductive status, age, and geographic distribution. Chi-square tests with post-hoc residual analysis identified significant demographic and breed variations across districts, while clustering based on standardized residuals grouped districts by distinct profiles. Geographic and socioeconomic distributions were assessed using the European Deprivation Index and urbanicity classification, with spatial visualizations generated in R and QGIS. The dataset includes 2,581,870 dogs, with a predominance of younger dogs (ages 2–3 years), a slight male majority (51.6 %), and 54.4 % neutered. Mixed-breed dogs were most common (39.6 %), followed by Portuguese Podengo (10.9 %) and Labrador Retriever (6.1 %). Age distributions varied geographically, with younger dogs in rural areas and older dogs in urban settings. Rural regions had higher dog-to-household ratios, while urban and economically deprived areas had higher absolute dog numbers but lower ratios. The findings establish baseline data for canine studies and highlight social patterns in the dog population. They underscore the role of rural areas in preserving native Portuguese breeds and the need for targeted public health and veterinary initiatives. By integrating demographic, geographic, and socioeconomic factors, this study provides key insights to inform public health and animal welfare policies, advocating for tailored strategies to meet the diverse needs of urban and rural canine populations.</div></div>","PeriodicalId":23505,"journal":{"name":"Veterinary journal","volume":"312 ","pages":"Article 106349"},"PeriodicalIF":2.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, there is no universal objective assessment method for DJD-associated pain in cats. Developing an accurate evaluation model could enable earlier treatment, slow disease progression, and improve cats’ well-being. This study aimed to predict early signs of DJD in cats using accelerometers and machine learning techniques.

Fifty-six cats were fitted with collar-mounted sensors that collected accelerometry data over 14 days, with data from 51 cats included in the analysis.

The main objective of the study was to develop and optimize a method for isolating equine adipocytes and to characterize their metabolic activity. Using slaughterhouse-derived horse visceral adipose tissue, we developed a protocol to isolate mature adipocytes. Metabolic activity of cells was assessed by examining their sensitivity to lipolytic factors: isoproterenol (0.001–10 µM), epinephrine (0.001–1 µM), and forskolin (0.001–1 µM)—and lipogenesis intensity after stimulation with insulin. We obtained mature equine adipocytes with diameters ranging from 50 to 160 µm. These cells demonstrated full metabolic functionality, responding to lipolytic factors such as isoproterenol (all doses: p &lt; 0.001), epinephrine (0.01 µM: p &lt; 0.05; 0.1–1 µM: p &lt; 0.0001), and forskolin (0.001 µM: p &lt; 0.0001).

The AHMF targeted key developmental areas: welfare advocacy, clinical expertise, communication, kit content and maintenance, and clinical governance. Monthly assessments were carried out using the AHMF scoring tool, and the results were analyzed using the Friedman test across these five competencies. The results showed statistically significant improvements in all aspects.

The average total AHMF score of the participants increased from 13.14 to 22.37, thus emphasizing all-rounded improvements in veterinary practices. The outcomes suggest that formal mentoring through the AHMF significantly enhances veterinary professionals' ethical and technical competencies, particularly in resource-poor settings.
