男性不育症 微小核糖核酸-145
2021/3/17
探讨男性不育症患者精浆中miR-145 的表达水平及其临床意义。方法 招募2017 年1 月~ 2018 年9 月 男性不育症患者130 例和同期体检正常的生育男性50 例为正常对照组。采用实时荧光定量PCR 检测精浆中miR-145 的 表达水平，精液常规参数采用WLJY-9000 伟力彩色精子检测系统进行分析。应用ROC 曲线分析miR-145 对男性不育症 的诊断价值，采用Pearson 相...
医学专家发现新的人未成熟卵母细胞体外培养模式
未成熟卵母细胞 新华网 培养模式
2023/4/3
记者从安徽医科大学获悉，该校曹云霞教授领导的第一附属医院生殖医学团队探索研究了褪黑激素对控制性超促排卵周期（COH）中人未成熟卵母细胞体外发育潜能影响，首次建立了新的人未成熟卵母细胞体外培养模式，可以增加试管婴儿周期中女性卵子再利用率。这一成果近日发表在国际主流学术期刊《松果体研究（Journal of Pineal Research）》上。

雌激素拮抗剂对三疣梭子蟹卵巢发育及相关基因表达的影响
三疣梭子蟹 卵巢发育 雌激素拮抗剂 基因表达
2019/1/22
通过活体注射、养殖实验和荧光定量PCR等方法，研究了不同浓度他莫昔芬（TAM）对三疣梭子蟹雌体成活率、卵巢指数、肝胰腺指数及卵巢发育相关基因表达的影响。结果显示，不同浓度TAM对雌体存活率和肝胰腺指数均显著影响，但在一定程度上抑制了卵巢指数。不同组织中的卵黄蛋白原（Vg）、雌激素相关受体（ERR）、维甲酸受体（RXR）和蜕皮激素受体（EcR）基因表达均受到了TAM的影响，Vg基因在卵巢和肝胰腺中的...
