查询词典 folate

Studies have shown that adequate intake of folate by women just before and during pregnancy significantly reduces the risk of neural tube birth defects, such as spina bifida or anencephaly.

研究表明，摄入足够的叶酸的妇女只是前和怀孕期间显着减少的风险，神经管先天缺陷，如脊柱裂或anencephaly 。

Since 1998 the US has required mandatory fortification of all grain products with folic acid - the synthetic, bioavailable form of folate - in order to reduce the incidence of neural tube defects - most commonly spina bifida and anencephaly.

从1998年开始美国就要求强化所有谷物中的叶酸含量--它是综合的，生物可利用性形式的叶酸盐--目的是为了减少神经管缺陷的患病风险-最常见的病症是脊椎裂和无脑畸形儿。

Reference: The association of folate, zinc and antioxidant intake with sperm aneuploidy in healthy non-smoking men.

参考：协会的叶酸，锌和抗氧化剂摄入量与精子染色体非整倍体健康的不吸烟的男子。

However, this study cannot prove that high folate intake caused the lower sperm aneuploidy levels, only that there is an association.

不过，这项研究并不能证明高叶酸摄入量较低所造成的精子非整倍体的水平，只是有一个协会。

Objective To explore the association between the level of folate,VitB12 and acute cerebral infarction disease.Methods 88 acute ischemic cerebrovascular stroke disease events were disparted in two subgroups,32 of arteriosclerotic cerebral infarction,56 of lacunar cerebral infarction,and 35 contrast group were set up.All the participants' serum folate,VitB12 were measured when they entered the hospital.

目的 探讨急性脑梗死患者血清叶酸、VitB12水平及其临床意义方法对88例首次发病的急性缺血性脑中风患者分两亚组，动脉硬化性脑梗死组32例，腔隙性脑梗死组56例，并设对照组35例，入院后用罗氏公司Elecsys 2010型全自动电化学发光免疫分析仪测定血清叶酸、VitB12浓度。

AtDFA is dihydrofolate synthase localized in mitochondria, it catalyzes one glutamate added to the dihydropteroate and produces dihydrofolat. AtDFB, AtDFC and AtDFD are folylpolyglutamate synthase localized in plastid, mitochondria and cytosol respectively. A short chain ofγ-linked glutamates can be added by FPGS.Folate molecules exist in vivo mainly as polyglutamates and these are preferred by folate-dependent enzymes.

AtDFA为二氢叶酸合成酶(dihydrofolate synthase，DHFS)，定位于线粒体，在它的催化作用下，一个谷氨酸分子与二氢蝶酸(dihydropteroate ， DHP)相结合，形成二氢叶酸；AtDFB、AtDFC、AtDFD为多聚谷氨酸合成酶(folylpolyglutamate synthase，FPGS)，分别定位于质体、线粒体和细胞质，在多聚谷氨酸合成酶的作用下，谷氨酸分子可以逐一连接到四氢叶酸的谷氨酸γ位。

Glyceryl trinitrate induced dilatation: GTN, high sensitive C reactive protein, tHcy, serum folate, red cell folate and lipids.

干预前、后分别检测血管内皮功能、血管平滑肌功能（硝酸甘油介导的血管平滑肌舒张GTN）、高敏C反应蛋白、血浆总高半胱氨酸、血浆红细胞叶酸盐和血脂。

Glyceryl trinitrate induced dilatation: GTN, high sensitie C reactie protein, tHcy, serum folate, red cell folate and lipids.

干预前、后分别检测血管内皮功能、血管平滑肌功能（硝酸甘油介导的血管平滑肌舒张GTN）、高敏C反应蛋白、血浆总高半胱氨酸、血浆红细胞叶酸盐和血脂。

A 4 weeks folate depletion period was judged to be optimal on the basis of the development of nadirs in both plasma and hepatic folate stores and elevated concentrations of plasma homocysteine.

血浆之叶酸含量及肝脏中储存的叶酸量，餵饲半纯化饲粮的鸡只，在耗竭期的第四周时，已降至谷底；而血浆高半胱胺酸之浓度则随饲养时间的增长而显著升高（P＜0.05），并且持续升高。

These data also support the use of both plasma folate and homocysteine as sensitive response criteria for folate status in pullets.

饲粮中添加不同型态叶酸，对鸡只的平均每日体增重、饲料采食量及饲料利用效率之差异则不大。
