Van Cauter's team found that when the 12 men in their study slept for four hours on two consecutive nights, their levels of leptin were 18 percent lower and their levels of ghrelin were 28 percent higher than they were after two nights of spending 10 hours in bed.

科学家还发现，缺乏睡眠的男子对自己的食量和"饥饿等级"的评估也平均上升了24%，他们要的食物多是一些甜食，或者炸薯条和坚果之类的咸食，还有淀粉含量很高的面包和通心粉等。

Results We found GM1 antibody in 36% and cephalin antibody in 43% of MS patients in serum,GM1 antibody in 11% and cephalin antibody 18% in cerebrospinal fluid.The levels of antibody in serum of treated_MS patients were significantly lower than those in active MS patients.The levels of myelin basic protein in serum and cerebrospinal fluid in MS were significantly higher than those in control group.

结果 多发性硬化患者血清GM1抗体阳性率 36%，脑磷脂抗体为43%；脑脊液GM1抗体为11%，脑磷脂抗体为18%，与对照组比较差异均有显著性；血清和脑脊液的髓鞘碱性蛋白增高亦有意义。

More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点，首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合，发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大，具有单分散性；较多的纳米粒子导致较大的乳液粒径；反应温度升高，凝聚物含量下降，而乳液粘度和乳胶粒粒径增加，在相同的反应温度下，纳米粒子降低了聚合过程中的凝聚物含量，增加了乳液聚合物的粘度和粒径；不论纳米粒子是否存在，当无皂乳液核组成中亲水单体AA和HEMA用量增加时，乳胶粒粒径均减少。

In particular, transgenic maize expressing higher levels of a protein designed to exhibit increased toxicity toward Coleopteran pests deliver superior levels of insect protection and are less likely to sponsor development of populations of target insects that are resistant to the insecticidally active protein.

特别是，设计一种蛋白以表现出对鞘翅目害虫提高的毒性，表达较高水平的这种蛋白的转基因玉米表现出优越的昆虫防治水平，并不太可能引起产生抗所述杀虫活性蛋白的目标昆虫群体。

It goes without saying that the higher levels should maintain close relations with the lower levels and that these should be comradely.

毫无疑义，上下级的关系应当密切，应当是一种同志的关系。

An index is calculated as the ratio of the economic loss estimated by using the continuity method and the economic loss calculated by using the discrete method with different seismic performance levels.The minimum number of performance levels is considered as the rational result when the index is within a prescribed small range.

这在1994年美国北岭、1995年日本阪神和1999年台湾集集地震中，由于不能有效地控制结构破坏而带来了巨大的经济损失[4-5]，远远超出了预先的估计。

At that level, the main difference of the system to provincial and prefecture levels is the callback counterfoil subsystem of certificates, seals and marks. The subsystem was divided into three levels from simple to intricacy.

县级证章标志管理与省级、市级明显不同之处是证章标志回收工作，该系统将回收子系统从简到繁在三个层次上对证章标志回收进行管理，满足对回收票据不同层次上的信息管理需求。

According to the Theory of Levels of Processing (Craik, 1972), memory is a dynamic activity of mind which may be affected by different levels or degrees of information processing.

该理论认为，人类大脑对信息的记忆和存储是一个动态过程，它可以反映出大脑在信息加工时对信息感知和理解的程度。

Then, the high and low tidal levels for engineering design were calculated based on the predicted results, and the tidal level corresponding to the cumulative frequency 99% of hourly-varied data series of tidal levels accorded with that corresponding to the cumulative frequency 90% of the data of low tidal level.

利用预报结果计算了工程设计高、低潮位，时序潮位累积频率99%对应的潮位与低潮位序列数据累积频率90%对应的潮位一致。

The levels of FOXP3, GITR and CD25mRNA in peripheral blood mononuclear cells were measured by the Light Cycler fluorescence quantitative PCR instrument, and the levels of serum thyroid hormone, TPOAb and TGAb were measured by electrochemiluminescence.

应用实时荧光定量PCR法检测各组外周血单个核细胞中FOXP3、GITR及CD25 mRNA含量，同时利用电化学发光的方法测定各组血清甲状腺激素水平及甲状腺过氧化酶抗体、甲状腺球蛋白抗体的水平。
