This article summarizes the key stages, applications, clinical potential, and recommendations for data standardization in 3D morphometrics. Datasets are typically acquired using radiological modalities, including computed tomography (CT), magnetic resonance imaging (MRI), and 3D surface scanning, each offering specific advantages and constraints contingent on the research context. Standardized landmark sets are essential in 3D morphometric studies to ensure reproducibility and comparability of results across independent investigations. Consistent use of reference landmarks enables repeatable analyses, but the number of landmarks directly influences the required sample size and statistical power. Consequently, a minimal yet balanced landmark configuration is critical. This article proposes a standardized, minimal landmark set for the skulls of horses, cattle, and sheep to enhance inter-study reproducibility and comparability. Landmark selection prioritizes anatomically distinct points to avoid excessive landmarking, which may complicate analyses or compromise interpretability. Applications of 3D morphometric methods include orthopedic surgical planning, biomechanical modeling, and assessment of congenital anomalies, providing enhanced precision in diagnostics and research. In conclusion, 3D geometric morphometric methods represent a robust analytical framework in veterinary anatomy, morphology, and clinical research. Their significance is poised to grow through integration with automated landmarking, artificial intelligence-driven analyses, and international data-sharing networks, thereby advancing scientific inquiry in novel dimensions.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"29 1","pages":"147-156"},"PeriodicalIF":1.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147489001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long-term hyperglycemia triggers molecular changes that damage retinal neuronal tissues and blood vessels, leading to degeneration, inflammation, and vision impairment.

We hypothesized that the deletion of either RAGE or Diaph1 would be beneficial and prevent or delay damage to the retinal structure in diabetes. Wild-type, RAGE and Diaph1 knockout mice were used in the study. The mice were randomly selected and divided into control and diabetic groups. Diabetes was induced with Streptozotocin injections, and six months after diabetes induction all mice were sacrificed, samples collected and processed for morphometric analysis. Our analysis revealed a reduction in retinal depth across all layers between control and diabetic samples. The effect of RAGE or Diaph1 deletion on retinal structure differed, indicating that both proteins may play independent if not interchangeable roles in retina function and structure, highlighting their potential role in the pathogenesis of diabetic retinal complications.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"29 1","pages":"127-131"},"PeriodicalIF":1.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147489152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, humans often have forms of MVR that do not qualify for conventional heart surgery or existing minimally invasive mitral valve repair methods. Transapical Transcatheter Edge-to-Edge Repair (TEER) of the MV is an innovative new method that uses special clips that are inserted into the heart through apical punctures. This technique enables effective closure of the defective valve without necessitating a traditional thoracotomy or opening the heart.

In this study, 150 fresh fecal samples from wild birds living alongside humans (crows and seagulls living along the coastlines, and pigeons living in tourist areas in the city center) were collected from various regions of Istanbul, Türkiye. For Campylobacter isolation, mCCDA agar was inoculated, and suspected isolates identified as Campylobacter spp. by biochemical tests were identified by PCR. The phenotypic and genotypic antimicrobial susceptibility profiles of the isolated strains were determined. When fecal samples were examined using conventional methods, Campylobacter spp. was isolated from 2/150 (1.33%). As a result of mPCR applied to DNAs obtained directly from the examination samples, 16 Campylobacter spp. were found in 15/150 (10%). 14 of these (93.3%) were identified as C. coli, and 2 (12.5%) were identified as C. jejuni. Campylobacter was detected in 11 of 127 pigeons (8.66%), while 10 (7.87%) were identified as C. coli, and 2 (1.57%) were identified as C. jejuni; Campylobacter was detected in 4 of 22 seagulls (18.18%), and all were identified as C. coli. When the sample collection regions were compared, the frequency of Campylobacter spp. was highest in Beyazıt Square (60%), followed by Küçükçekmece Beach (40%). As a result of antimicrobial susceptibility tests and PCR performed for the presence of tet(O), aphA-3 and gyrA genes, gyrA gene was found in both isolates, while tet(O) and aphA-3 genes were not detected.

A key pathological outcome of PEDV infection is the induction of oxidative stress, which significantly exacerbates intestinal injury and accelerates disease progression. Natural bioactive compounds, sourced from plants, animals, and microorganisms, have been extensively studied for their diverse biological properties, including potent antioxidant, anti-inflammatory, and antiviral activities. These compounds demonstrate significant potential in alleviating oxidative stress and playing a pivotal role in the prevention and management of PEDV infections. This review provides a comprehensive analysis of the mechanisms by which natural bioactive compounds enhance the antioxidant defence system and suppress PEDV replication. Current evidence indicates that these compounds alleviate oxidative stress primarily through the modulation of antioxidant enzyme systems, such as superoxide dismutase (SOD) and glutathione peroxidase (GPx), and the activation of key signalling pathways, including the Nrf2/ARE axis. These actions collectively contribute to reduced viral loads and improved health outcomes in PEDV-infected pigs. Although these findings underscore the potential of natural bioactive compounds, several critical challenges persist, particularly the incomplete elucidation of their mechanisms of action and the substantial costs associated with large-scale applications. Addressing these challenges necessitates further research aimed at uncovering the precise molecular pathways underlying their effects and developing cost-effective strategies to facilitate their practical implementation in the swine industry.","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"29 1","pages":"165-174"},"PeriodicalIF":1.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147489057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
