咖啡因

Caffeine improved the memory skills and reactions times of the volunteers. In addition, caffeine increased brain activity in two locations-the memory-rich frontal lobe and the attention-controlling anterior cingulum.

咖啡因提高了志愿者记忆的技巧和反应时间，此外，咖啡因能够活跃两个地方的大脑组织：位于额叶的记忆区带和位于扣带回的情绪调控区带。

John Kassotis, MD, associate professor of medicine at SUNY Downstate, said, The protection against death from heart disease in the elderly afforded by caffeine is likely due to caffeine's enhancement of blood pressure.

"约翰kassotis医学博士，副教授，中医在纽约州立大学downstate说，"保护，防止严重心脏病的中老年人所给予的咖啡因，可能是由于咖啡因的提升血压。

Three hours after you drink a cup of coffee, the level of caffeine in your blood will be half of what it was at its peak.

喝下一杯咖啡，三个小时后，在你血液中的咖啡因有一半被高度吸收；六个小时后，大部分的咖啡因在你体内体统消除。

Methods: Sixty-five male C57BL/6J mice were randomly assigned to five groups: caffeine (10 mg/kg), caffeine (50 mg/kg), DPCPX (5 mg/kg),SCH58261 (5 mg/kg) and saline,by intraperitoneal injection right after the completion of the behavioral training.

C57BL/6J雄性小鼠65只，分成咖啡因低剂量组（10 mg/kg，n =15）、咖啡因高剂量组（50 mg/kg，n=15）、DPCPX组（5 mg/kg，n=10）、SCH58261组（5 mg/kg，n=10）和生理盐水对照组（n=15）。

The reciprocity between PPCG and caffeine molecule was also simulated and calculated.It was found that the caffeine molecule was selectively distributed in CO2 habitat,but never in γ-butyrolactone habitat.

通过对PPCG与药物分子咖啡因相互作用的分子模拟和计算，进一步了解咖啡因分子是选择性地分布到CO2结构单元的区域中，而在GBL区域无分布。

Two synthetic routes of Caffeine have been determined and investigated after the analyzing and trying for the literal synthetic methods. In one route, the target compound was prepared from chloroacetyl chloride through six steps, the total yield is 50.5 %. In another route, the target compound was obtained from cyanoacetic acid through six steps, the total yield is 45%.

对目前咖啡因工业生产工艺进行了研究，并分析了咖啡因工业生产中所存在的问题，本文提出两条可行的工业化合成路线：一条是以氯乙酰氯为起始原料，经过六步反应制得目标化合物，总收率50.5％；另一条是以氰基乙酸为起始原料经过六步反应制得目标化合物，总收率45％。

However, continuous use of caffeine devitalizes the body to the point that the body cannot function without it.
