Antagonism of MR ablates the normal synthesis of progesterone in response to hCG although the mechanism remains unclear.;It was also concluded that even though mural granulosa cells are less likely to proliferate in response to exogenous stimulus in the form of epidermal growth factor after hCG, proliferation can be enforced in even luteinizing granulosa cells using insulin.

Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4
从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D(图1),被用来决定病人体内维生素D情况的1,2,3,4;25-羟基维生素D在肾中被25-羟基维生素D1羟化酶(CYP27B1)转变为有活性的1,25-二羟基维生素D 。1,2,3,4由肾产生1,25-二羟基维生素D是被血浆甲状旁腺激素和血清钙,磷水平紧密调节。1,2,3,4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1,25-二羟维生素D合成。5 在1,25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2,3,6 它也包括25-羟四- 24 -羟化酶的表达(CYP24),且将1,25二羟基维生素D和25羟基维生素D异化成无生物活性,水溶性的维生素D3-23羧酸。2,3,4

The thiopeptides, by binding within a cleft located between the ribosomal protein L11 and helices 43 and 44 of the 23S rRNA, overlap with the position of domain V of EF-G, thus explaining how this class of drugs perturbs translation factor binding to the ribosome.
核糖体蛋白L11和23SrRNA的43/44螺旋结构形成裂隙,L11的构象变化能够加宽该裂隙从而允许延伸因子EF-G插入,促使GTP水解,为肽链延伸合成过程中核糖体的构象变化提供能量,而Thio能够与L11和23sRNA结合,阻止L11的构象变化,使该裂隙处于闭合状态,抑制EF-G在延伸过程中的作用。

For the first time, we found that the EHFV propagated in HUVEC has a potentiating stimulation to ET-1 and PGI〓 secretion , which may be respensible for the increased plasma ET -1 level and PGI〓 concentration in patients with EHF during the early phase of the disease.
我们的研究结果提示,HUVEC对EHFV敏感,EHFV感染未引起HUVEC的细胞病变,但可抑制HUVEC的增殖,这有可能改变EC的基因调节,或低调,如Ⅷ R:Ag合成障碍,引起止血功能异常;或高调,如主要组织相容性复合物Ⅱ型抗原、干扰素β和内皮细胞白细胞粘附因子的表达增加,增强EC的炎症反应。
