人体内脂肪酸(FFA)与糖相比具有贮量大、单位质量贮能高等特点,是长时间运动的理想能源。研究认为有氧训练可以提高骨骼肌对脂肪的氧化能力,但有关脂肪的研究远没有对糖的研究那样深入与广泛。结合近来的有关脂肪代谢的研究成果从脂肪组织的脂解和FFA的运输、FFA跨肌肉细胞膜的运转、FFA跨线粒体膜的运转、肌肉中甘油三酯(IMTG)的动用4个方面作几点探讨,旨在对运动与脂肪代谢的研究做一点贡献。 相似文献

Two kinds of activated ways are used to prepare activated coal gangue fine powder, one is calcining coal gangue
at 800 ℃ (gangue A), and the other is calcining coal gangue with a certain calcite at 800 ℃ (gangue B). The experiment
shows that strengths of blended cement mortar with coal gangue B are higher than that of blended cement with coal gangue
A. Hydration of cements with the two kinds of activated coal gangue is investigated through a differential thermal analysis.
The weight loss due to Ca(OH)2 decomposition of hydration products by differential thermal analysis/thermo gravimetric
(DTA/TG) can be used to quantify the pozzolanic reaction. A new method based on the composition of hydration cement is
proposed to determine the degree of pozzolanic reaction. The results obtained suggest that the degree of pozzolanic reaction
of gangue B is faster than that of gangue A. 相似文献

采用热重法(TG)测定了2-(4-甲氧羰基苯基)-5-氨基-6-羟基苯并嗯唑(MAB)的热分解过程,测定了MAB及其在热分解过程中不同阶段产物的红外光谱,运用量子化学GAMESS软件计算了MAB分子的键级,推断了MAB的热分解机理,结果表明MAB的热分解过程是一个五阶段过程,起始步骤是甲基酯的分解、根据不同升温速率下的热重曲线计算得到MAB第一阶段热分解反应的表观活化能Eα=157.1kJ·mol^-1和指前因子A=3.715×10^13。 相似文献

生成语法与笛卡尔天赋观念的再认识 总被引:2,自引:0,他引:2
何宏华 《北京师范大学学报(社会科学版)》2000,(4)
评析乔姆斯基生成语法理论与笛卡尔天赋观念说之间的关系 ,提出前者并非是对后者的简单继承 ,而是在扬弃了后者的基础上 ,以 2 0世纪中期西方哲学与自然科学的认识论和方法论为依托发展起来的当代语言学理论 ,澄清了国内外学者对二者之间关系的误解 相似文献

The present study was undertaken to explore the relationship of plasma homocysteine with other biochemical parameters in ischemic
heart disease. Plasma levels of total homocysteine was measured by HPLC—fluorescence detection with internal standard in 60
ischemic heart disease patients and were compared with 30 age matched normal healthy controls. The significant increase of
plasma homocysteine was observed in both myocardial infarction and chronic stable ischemic heart disease patients when compared
with the controls. The hyperhomocysteinemia appears be to due to increased body demand of vitamins such as folic acid, vitamin
B12, B6, B2 either alone or in combination to regulate normal homocysteine metabolism. 相似文献

Type 2 diabetes mellitus (DM) is a multifactorial disease where both genetic and environmental factors contribute to its pathogenesis.
Estrogen plays an important role in type 2 DM pathogenesis. A number of polymorphisms have been reported in the estrogen receptor
(ESR1), including the XbaI and PvuII restriction enzyme polymorphisms of ESR1,which may be involved in disease pathogenesis. Metallothioneins (MT) act as potent
antioxidants against various oxidative damages. Very few studies have indicated the association between Estrogen Receptor-α,
MT1 gene polymorphisms with type2 DM. A total of 100 type 2 diabetic women and 100 age, sex matched controls were recruited.
Using the PCR based RFLP method, the PvuII and XbaI polymorphisms of ESR1 and in MT1A (rs8052394 and rs11076161) gene polymorphisms were analysed. The genotype distribution and frequency of mutated allele showed no significant differences
between diabetic and non-diabetic groups in PvuII (χ2 = 2.443; P = 0.1181) or XbaI (χ2 = 1.789; P = 0.1812) and rs8052394 (χ2 = 1.154; P = 0.2840) or rs11076161 (χ2 = 0.4141; P = 0.5199), polymorphisms. This is the first Indian study to conclude that ESR1 and MT1 gene polymorphisms are not associated
with increased susceptibility to type 2 diabetes in Indian women. 相似文献
