概括

在诱导白质溶解后,奶牛的无细胞DNA (cfDNA) 水平上升. 这表明cfDNA可以作为检测白色溶解的血生物标志物,有助于生殖周期管理.

科学领域:

生殖生物学生殖生物学
生物化学生物化学
兽医医学兽医医学兽医医学

背景情况:

细胞死亡释放无细胞DNA (cfDNA) 进入循环.
质细胞在结构性质溶解过程中经历了亡,以启动新的雌性循环.

研究的目的:

为了调查cfDNA度是否会在骑自行车的奶牛中诱导解后增加.
评估cfDNA作为解的潜在生物标志物.

主要方法:

十五只安格斯奶牛进行了同步治疗,并接受了前列腺素F2α (PGF2α) 或对照的治疗.
使用超声波 (CL-A,LBP%) 和血孕激素 (P4) 监测流体溶解.
血cfDNA度在治疗后的四天内被测量.

主要成果:

PGF2α治疗成功诱导了白色分解,在12小时内减少P4和CL-A.
在PGF2α注射后36小时,状血 perfusion (LBP%) 显著降低.
在PGF2α应用后48小时观察到cfDNA度的显著增加.

结论:

在奶牛中诱导的解导致血cfDNA的显著升高.
cfDNA显示出作为一种非侵入性生物标志物的潜力,用于检测牛血中的解.

关键词:

cfDNA DNA 的时间.黄体体 (Corpus luteum) 是一个体.

Feedback Regulation of Calcium Concentration

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
