概括

维生素B12缺乏会给健康带来风险,尤其是素食饮食. 目前的建议可能无法确保足够的可巴拉明状态,特别是对于孕妇和婴儿.

科学领域:

营养科学营养科学
公共卫生公共卫生

背景情况:

维生素B12 (科巴胺) 对新陈代谢功能至关重要;缺乏维生素B12会对健康产生不良影响.
西方国家越来越多的素食主义可能会增加B12缺乏的风险.
设定足够的B12摄入量建议是具有挑战性的,因为可变的吸收,扩散的症状,和不清楚的缺陷值.

研究的目的:

评估当前维生素B12建议的充分性.
调查孕妇和婴儿等弱势群体的维生素B12状态.
倡导基于生物化学标记而不是临床迹象的摄入建议.

主要方法:

对北欧人口维生素B12摄入量数据的分析.
对孕妇和婴儿维生素B12状况的审查.
通过饮食摄入量与已建立的营养建议进行比较.

主要成果:

尽管报告的摄入量低于推值,但在挪威的孕妇和婴儿中,维生素B12缺乏是普遍存在的.
目前关于通过母乳进行足够的B12转移的假设是可疑的.
现有的建议可能不能保证最佳的可巴拉胺状态.

结论:

维生素B12缺乏是令人担忧的,特别是在婴儿和孕妇中.
目前的维生素B12摄入量建议可能不足.
评估维生素B12状态应依赖于生化标志物,以获得最佳的健康结果.

Applications Of NMR In Biology

Applications Of NMR In Biology

Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an analytical tool. F. Bloch and E. Purcell formulated NMR in 1946 and won the 1952 Nobel Prize in Physics for their work. Biological macromolecules such as proteins, nucleic acids, lipids, and organic molecules including pharmaceutical compounds, can be studied using this versatile tool that exploits the magnetic properties of certain nuclei.
