The focus of this study was on-site measurement technology. We evaluated the usefulness of resistive pulse sensing (RPS) particle measurement in comparison with standard measurement and the clinical findings of udder quarters in cows. We measured the particle count in milk samples collected from healthy udder quarters, calculated statistically normal values, and judged cases with significantly deviated values as abnormal. We found that abnormal values detected using RPS measurement corresponded to those using standard measurement. Furthermore, it was possible to identify which specific udder quarter was causing the abnormality, and this matched the abnormalities observed in clinical findings. RPS also enabled the detection of subclinical abnormalities in udder quarters showing no visible symptoms. RPS is a simple particle measurement method, and it cannot be used to diagnose disease directly; however, its use on-site can facilitate the early detection of abnormalities and help to maintain milk quality. Because the device used in RPS mainly measures electrical current, it can be manufactured at low cost, making RPS a promising tool for future point-of-care testing.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148882409","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}

The number of blood vessels was significantly greater in pedunculated masses than in nodular masses. Immunohistochemically, spindle- and stellate-shaped cells were positive for progesterone receptor in all 26 lesions, estrogen receptor in 5 of 26 lesions, desmin in 20 of 26 lesions, and α-smooth muscle actin (αSMA) in 8 of 26 lesions. Lesions in neutered dogs exhibited lower progesterone receptor expression and higher estrogen receptor expression than those in intact females. No significant differences in desmin or αSMA expression were observed between the two groups.

However, the information on the vascular pattern of this gland in pigs remains limited. This study elucidates the morphoanatomy and arterial supply of the gland in three breeds: Landrace (L), Large White (W), and Crossbreed (LWD). Two hundred twelve pigs were used and dissected to observe the arteries supplying blood to the gland. As a result, the gland was classified into three types based on its appearance: pear-shaped, butterfly-shaped, or partially separated. Moreover, the arteries supplying the gland were observed and then compared among breeds. The arterial supply of the thyroid gland on the cranial side consisted of branches from the cranial laryngeal artery, cranial thyroid artery, superficial cervical artery, and common carotid artery. Otherwise, the caudal side was supplied by the caudal thyroid artery, superficial cervical artery, bicarotid trunk, internal thoracic artery, and external thoracic artery. Furthermore, significant differences were identified between L and LWD, as well as between W and LWD, in the pattern of arterial origin on the cranial right side of the thyroid gland. Similarly, on the left side, significant differences were observed not only between L and W but also between W and LWD. On the caudal side, significant differences were found between L and W, as well as between W and LWD. These anatomical variations provide important insights for research and clinical applications involving the thyroid gland in pigs.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1285-1295"},"PeriodicalIF":1.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13616608/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148320331","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}

In recent years, MRSA (methicillin-resistant Staphylococcus aureus) has emerged as an important cause of chronic and recurrent mastitis, posing additional challenges for herd health management. The aim of this study was to conduct a comparative analysis of recurrent mastitis in Holstein-Friesian cows caused by MRSA and non-MRSA S. aureus, with a particular focus on the number of recurrences, somatic cell count (SCC), milk production, and risk factors. The study included 120 cows, divided into two groups of 60, raised under identical conditions on a single farm. Milk samples were collected under sterile conditions, cultured on Blood agar and Mannitol Salt agar, and analyzed for the presence of MRSA using PCR for the mecA gene. Cows were monitored for the number of recurrences, SCC, daily milk yield, and response to therapy. Statistical analyses included t-tests, ANOVA, correlation analysis, and logistic regression. The results showed that MRSA-infected cows had significantly higher recurrence rates, along with elevated SCC and reduced milk yield compared to the non-MRSA group. MRSA was identified as the strongest independent risk factor for mastitis recurrence. These findings highlight the importance of regular bacteriological monitoring, appropriate therapy, and preventive measures to reduce economic losses and protect herd health.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1371-1376"},"PeriodicalIF":1.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13612955/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148431367","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}

NCX plays essential roles in diverse physiological processes, including cardiac contraction, neuronal signaling, and hormone secretion, while its dysregulation is implicated in a wide range of pathophysiological conditions such as heart failure, ischemia, and neurodegenerative diseases. Recent advances in structural biology, particularly cryo-electron microscopy, have provided detailed insights into the molecular architecture of eukaryotic NCX, revealing the mechanisms underlying ion transport, regulation, and inactivation. These studies have highlighted the functional importance of conserved structural elements, including the α1- and α2-repeats and cytosolic regulatory domains, in governing exchanger activity. In parallel, pharmacological studies have identified a variety of NCX modulators with distinct mode and isoform selectivity. While classical inhibitors predominantly target the reverse mode, emerging compounds-including highly selective inhibitors and novel activators-demonstrate diverse mechanisms of action, often involving allosteric modulation rather than direct interaction with the ion-binding site. This review integrates current knowledge of NCX structure, function, and pharmacology, with a particular focus on the relationship between structural determinants and transport mode selectivity. We also discuss the challenges that have limited the clinical translation of NCX-targeting drugs and outline future perspectives for the rational design of next-generation NCX modulators.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1407-1418"},"PeriodicalIF":1.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13612953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148431424","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}
