The incisional biopsies and the whole mass were then histologically evaluated, and a grade was assigned. The agreement between the single biopsy and the definitive histology varied depending on the location of the biopsy (peripheral vs central).

This study aimed to evaluate whether a carbonate buffer mixture (CBM) could alleviate SARA-induced endometritis in dairy goats by modulating the microbiota and metabolic profiles. A total of 30 healthy lactating dairy goats with similar body weight were selected for the experiment. Inflammatory markers were assessed in both uterine tissue and serum. The microbial communities in the rumen and uterus were characterized using 16S rRNA gene sequencing, while alterations in serum metabolites were analyzed <em>via</em> untargeted metabolomics. The results demonstrated that CBM supplementation effectively reversed SARA induced by a high-concentrate diet, reduced neutrophil infiltration, LPS levels, and inflammatory cytokine concentrations in the endometrium, and enhanced the expression of tight junction proteins in uterine tissue. Additionally, CBM mitigated SARA-induced dysbiosis of the uterine microbiota by restoring the relative abundance of key bacterial taxa, including <em>Lachnospiraceae</em>, <em>Prevotella</em>, and <em>Ruminococcus</em>, while also modulating rumen bacterial populations such as <em>Stenotrophomonas</em>, <em>Aerococcus</em>, and <em>Acinetobacter.</em> Metabolomic profiling revealed that SARA significantly increased serum concentrations of creatinine, <span>L</span>-methionine, and <span>L</span>-tyrosine, while decreasing levels of tryptamine, gabapentin, and sphinganine. These findings suggest that CBM may restore rumen pH and microbial balance in SARA-affected goats, thereby influencing systemic metabolite profiles, promoting uterine microbiota homeostasis, reducing endometrial injury, and ultimately alleviating endometritis. Collectively, this study highlights a potential link between the ruminal microenvironment and uterine health, and provides new insights into the therapeutic role of CBM in managing SARA-induced endometritis.</div></div>","PeriodicalId":23505,"journal":{"name":"Veterinary journal","volume":"316 ","pages":"Article 106601"},"PeriodicalIF":3.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146220983","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}

Over two academic years (2022–23, n = 138 students; 2023–24, n = 125 students), two types of quizzes were evaluated: in-class quizzes for resolving doubts and self-assessment quizzes for exam preparation. Participation was generally high (&gt;80 % on average), except for in-class questionnaires in 2022–23 (67.9 %). Students perceived the quizzes as useful for exam preparation (96.2–97.1 %) and supporting learning (51.4–53.9 %). They also found them easy to use (96.2–97.1 %) and recommended their implementation in other subjects (77.1–96.2 %). Quiz completion and performance were generally positively correlated with exam outcomes. Among the different formats, cloze and matching questions were the most effective. However, cloze questions varied in discriminative efficiency, while multiple-choice questions demonstrated significantly lower discrimination. Student perceptions of question difficulty and of which questions best reflected knowledge varied between cohorts.
