LFTS procedures were performed on 12 canine hindlimb cadaveric models divided into five groups: (1) Intact group, (2) cranial cruciate ligament-deficient (CCL) group, and (3-5) stifles fixed at 90°, 105°, and 135° (L90, L105, L135). Suture tension was quantitatively measured using a tensioner. Postoperative evaluations included pedobarography, tibial rotation angle, patellofemoral contact pressure, and femorotibial contact pressure, analyzed via force-sensitive resistors and pressure-sensitive films. Pressure mapping visualizations were used to evaluate joint mechanics and pressure distribution. Statistical analyzes were conducted using two-way ANOVA with post-hoc testing. The applied suture tension differed significantly among angle-fixed groups (P<0.05). Significant correlations were observed between experimental groups and pad pressure distribution (P<0.001). No significant difference in femorotibial contact pressure was noted between the L105 and intact groups. These results suggest that a stifle angle of 105° during LFTS most closely replicates normal joint contact mechanics, offering practical insights for optimizing tensioning protocols in small dogs.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report observations from four genetically identical cloned working dogs exposed to different environments, including an airport and a police station, for two years. Hair and fecal samples were collected to assess potential environmental influences on mineral content and intestinal microbiota composition. The concentrations of toxic minerals, such as Pb and Ni, were significantly higher in the hair mineral analysis of the dog exposed to the airport compared to those of the three police station-working dogs. Fecal microbiota analysis showed that the intestinal microbiota of the airport-exposed dog was simplified, with an increased proportion of Actinobacteria and a decreased proportion of Lachnospiraceae and Fusobacteria. Our observations suggest that environmental conditions may influence the accumulation of harmful substances in the body and affect intestinal microbiota community. This finding also highlights the potential of non-invasive methods for evaluating workplace-related environmental influences on working dogs. These results suggest that different environments may contribute to physiological differences even among genetically identical individuals. Future studies should investigate the mechanisms underlying these variations and assess their long-term implications for canine health monitoring with larger sample sizes.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1141-1148"},"PeriodicalIF":1.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12508561/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144976723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate their interaction in the tick Haemaphysalic longicornis, we employed AlphaFold2 to model the β-barrel domain of the midgut-synthesized paralog HlVtg1 and the first three ligand-binding repeats (LBR1-3) of HlVtgR. Subsequent protein-protein docking in Molecular Operating Environment (MOE) revealed a recurrent binding interface centered on HlVtg1's Glu87, which formed persistent electrostatic interactions with LBR1-3 across top-ranking poses. Our results support a \"monomeric engagement\" model, where a single HlVtg1 monomer simultaneously engages all three low-density lipoprotein receptor class-A (LDLRA) domains of HlVtgR. This mechanism contrasts with the classical dimeric model and challenges prior inferences about stoichiometry and symmetry of binding sites. The predicted contact residues defined here may serve as a useful basis for evaluating candidate epitopes for interventions aimed at disrupting oocyte maturation and transovarial transmission of pathogens in H. longicornis.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the prevalence, genotype distribution, and phylogenetic characteristics of PaBV in captive psittacine birds in Thailand. A total of 231 birds from three families (Psittaculidae, Psittacidae, and Cacatuidae) were sampled across five regions in Thailand. Nested PCR targeting the nucleoprotein gene detected PaBV in 13.85% (n=38) of samples, with 81.58% of positive cases being asymptomatic, suggesting a potential carrier state. Choanal swabs were the most effective for detecting PaBV, although some positive cases were identified exclusively in other specimen types, indicating the importance of using multiple sample types for accurate diagnosis. Genotyping revealed the presence of two viral variants: PaBV-2 and the more prevalent PaBV-4, with the latter being predominant and further classified into two distinct groups. The continued presence of PaBV in captive birds raises concern over possible spillover into native wild psittacine populations, several of which are classified as \"Near Threatened\" by the IUCN. These findings underscore the importance of regular monitoring and molecular surveillance in both captive and wild bird populations to inform effective disease management and conservation strategies.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six cats with colorectal adenocarcinoma underwent tumor resection using Swenson's pull-through technique were included. Clinical records were retrospectively reviewed to assess perioperative complications, completeness of resection, disease-free survival (DFS), and overall survival (OS). All tumors, with a resection margin of 2cm, were involved the pelvic cavity, and the median tumor size was 2.0 cm. In all cases, the horizontal resection margins were histologically clear, and metastasis was histologically confirmed in the left colonic lymph nodes. Five cats experienced diarrhea as a short-term postoperative complication during hospitalization, which resolved within approximately 1 month. One cat developed colonic stenosis that was managed with balloon dilation. The median DFS and OS were 150 and 225 days, respectively.

In this study, we examined fecal samples collected from wild birds in two prefectures of Japan between 2021 and 2024 using both deoxycholate-hydrogen sulfide-lactose (DHL) agar media and antimicrobial-containing DHL agar media. Of the 252 fecal samples from 11 bird species, 159 E. coli were isolated from 70 samples (27.8%) of six species, and resistance was found in 4.4% of isolates from DHL media. Using nalidixic acid (NAL)- and cefotaxime (CTX)-containing media, NAL-resistant isolates were isolated from great cormorants and spot-billed ducks, and an extended-spectrum β-lactamase (ESBL)/AmpC β-lactamase producer was isolated from great cormorants. Next-generation sequencing analysis of 19 E. coli isolates exhibiting resistance to NAL and/or CTX indicated diverse genotypes. Genetic analysis indicated that amino acid substitution of quinolone-resistance-determining-regions and qnrS were responsible for NAL resistance, and CTX-Ms (blaCTX-M-14 in three isolates, and blaCTX-M-15 and blaCTX-M-55 in each) and AmpC β-lactamase (blaMOX-4 and blaCMY-2 in each) were responsible for CTX resistance.
