However, diagnosing heart disease generally requires specialized techniques such as ultrasonography. This study focused on cardiac hormones that can be used to detect cardiac disease from blood tests. We measured concentrations of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in healthy young Japanese macaques (Macaca fuscata) housed individually indoors, with no abnormalities in thoracic X-rays, electrocardiograms, echocardiograms, or complete blood counts and serum biochemistry tests, to establish reference values. The monkeys used in this study comprised 29 males (28-47 months old) and 29 females (22-65 months old). ANP levels were determined by immunoradiometric assay. BNP levels were determined by chemiluminescent enzyme immunoassay. Mean ANP level was 25.7 ± 9.6 pg/mL for all 58 Japanese macaques, 26.7 ± 9.6 pg/mL for the 29 males, and 24.7 ± 9.5 pg/mL for the 29 females. No significant difference was identified between sexes. No correlation was seen between ANP and age but excluded monkeys showed result of outside these range. BNP was also measured, with 22 of the 58 monkeys showing levels below the lower limit of detection (<4.0 pg/mL). Taking levels in these 22 animals as 4.0 pg/mL, mean BNP level was 5.1 ± 1.6 pg/mL and BNP elevated in two excluded monkeys. These results establish mean values for cardiac hormones in young Japanese macaques. These standards may provide useful indicators for the early detection of cardiac disease in animal models.</p>","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143434174","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}

Adjuvant chemotherapy administration is commonly applied in MIBC cases, but patients sometimes experience treatment failure and recurrence. Therefore, supplements with anticancer properties, such as traditional Chinese medicines (TCMs), are required, and they have been widely used in Japanese human medicine and may be useful in veterinary medicine. Furthermore, organoid cultures can mimic the characteristics of their original tissues, such as self-renewal and organization. We previously established a novel experimental model for MIBC using a dog BC organoid (DBCO) culture. Herein, we examined the antiproliferative effects and mechanisms of 39 substances, consisting of TCMs, TCM supplements, and crude drug extracts, on DBCOs. Among the TCMs, D3 (also known as Shibe-ria), which is a mixture of chaga (Inonotus obliquus) and notoginseng (Panax notoginseng), significantly diminished the cell viability of DBCOs. The expression of BC stem cell markers, CD44 and SOX2, was reduced considerably in the D3-treated DBCOs. Among the components of D3, chaga exerted an antiproliferative effect on DBCO, whereas notoginseng did not. The administration of D3 also significantly reduced the volume of DBCO xenografted tumors in mice in vivo.

With the growing challenge of acaricidal resistance, the demand for alternative control measures is urgent. However, effective PRM research, particularly in acaricidal efficacy and new drug discovery, hinges on the availability of reliable laboratory colonies. In this study, we successfully established a stable PRM laboratory colony, originally isolated from the field in 2021 and maintained under controlled conditions at the Research Institute for Animal Science in Biochemistry and Toxicology (RIAS). We investigated the growth kinetics and population dynamics of the laboratory colony within a Styrofoam-based maintenance box (SBMB) containing chicks. PRM propagation was tracked over 28 days, with mites collected every seven days. The average bulk weight of the mites in the trap increased from 4.3 ± 1.2 mg on day 7 to 201.4 ± 56.5 mg on day 28, despite seasonal variations, indicating optimal conditions for population growth. The collected mites spanned various blood-feeding developmental stages such as protonymph, deutonymph, and adult stages, enabling comprehensive assessments of molting and egg-laying efficiency.

Body size and mechanical stress impact the bone formation and homeostasis, yet the specific developmental processes remain unclear. Here, we demonstrate the histological changes in whale long bones from fetal to mature stages using the radius of Antarctic minke whales in comparison with domestic cats and cattle. Through intramembranous ossification and remodeling, long bones enlarge their diameters and marrow cavities, respectively. It has been demonstrated that relatively small animals, such as cats, develop the radially arranged \"primary osteonal bone\", whereas larger animals, including cattle, form \"laminar bone\" initiated by the formation of circumferentially arranged hypercalcified lines during intramembranous ossification. Here, we demonstrated that whales form laminar bones, transitioning from circumferential in the fetus to radial during postnatal growth, and thereafter cortical bones become compact. After maturation, bone remodeling primarily occurs in the lateral and medial regions of long bones, while the bone layers in the cranial-caudal region never undergo complete resorption. As a result, these layers remain as a wire-netting structure composed of thin bone layers, without forming an open medullary cavity. These data suggest that whales enlarge their long bones through laminar bone formation and form long bones without a marrow cavity by regulating bone resorption areas during the developmental process and in maintaining homeostasis.</p>","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143410894","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}
