  • Differences in Frequency of the Deletion Polymorphism of the Angiotensin-Converting Enzyme Gene in Different Ethnic Groups
    作者:James Mathew、Khaja Basheeruddin、Suresha Prabhakar
    DOI:10.1177/000331970105200602
    日期:2001.6

    A polymorphism characterized by the insertion or deletion of a 287-bp Alu repeat sequence in intron 16 of the angiotensin-converting enzyme gene determines about half the serum angiotensin-converting enzyme level variability among individuals. The deletion polymorphism is associated with higher levels of angiotensin-converting enzyme and perhaps with a greater risk of cardiovascular diseases. The relative frequency of this genetic polymorphism in different ethnic groups is not known. The objective of this study was to compare the frequency of angiotensin-converting enzyme gene insertion/deletion polymorphism in different ethnic groups. Angiotensin-converting enzyme genotype was determined in middle-aged healthy hospital workers of three different ethnic origins (African Americans, whites, and Indians). There were 142 African Americans, 136 Indians, and 82 whites. The distribution of the deletion-deletion, insertion-deletion, and insertion-insertion genotypes in African Americans (29%, 60%, and 11 %, respectively), Indians (19%, 50%, and 31 %, respectively) and whites (29%, 40%, and 31 %, respectively) was significantly different (p = < 0.005). The frequency of the deletion allele among African Americans, Indians, and whites (0.59, 0.49, and 0.44, respectively) was also significantly different (p = 0.05). African Americans had the highest frequency of deletion allele and the lowest frequency of the insertion-insertion genotype among the three groups. The frequency of the deletion polymorphism of the angiotensin-converting enzyme gene is different among African Americans, whites, and Indians. This may be important in relation to the high risk of cardiovascular morbidity and mortality in African Americans and may be relevant in explaining differences in cardiovascular diseases in different populations. This finding also emphasizes the importance of studying angiotensin-converting enzyme gene polymorphism in genetically homogenous populations. Because of the small size of this study, however, these findings need further confirmation.

    一种多态性特征,由血管紧张素转换酶基因内含子16中的287-bp Alu重复序列的插入或缺失决定了个体间大约一半血清血管紧张素转换酶水平的变异性。缺失多态性与更高水平的血管紧张素转换酶以及可能更高的心血管疾病风险相关联。不同种族群体中这种遗传多态性的相对频率尚不清楚。本研究的目的是比较不同种族群体中血管紧张素转换酶基因插入/缺失多态性的频率。在三个不同种族起源(非裔美国人、白人和印第安人)的中年健康医院工作者中确定了血管紧张素转换酶基因型。有142名非裔美国人、136名印第安人和82名白人。非裔美国人(分别为29%、60%和11%)、印第安人(分别为19%、50%和31%)和白人(分别为29%、40%和31%)的缺失-缺失、插入-缺失和插入-插入基因型的分布显著不同(p = <0.005)。非裔美国人、印第安人和白人的缺失等位基因频率(分别为0.59、0.49和0.44)也显著不同(p = 0.05)。非裔美国人的缺失等位基因频率最高,插入-插入基因型频率最低。血管紧张素转换酶基因的缺失多态性在非裔美国人、白人和印第安人中不同。这可能与非裔美国人心血管发病率和死亡率高的情况相关,并可能有助于解释不同人群心血管疾病的差异。这一发现也强调了在遗传同质人群中研究血管紧张素转换酶基因多态性的重要性。然而,由于本研究规模较小,这些发现需要进一步确认。
  • Direct Synthesis of Renewable Dodecanol and Dodecane with Methyl Isobutyl Ketone over Dual-Bed Catalyst Systems
    作者:Xueru Sheng、Ning Li、Guangyi Li、Wentao Wang、Aiqin Wang、Yu Cong、Xiaodong Wang、Tao Zhang

    For the first time, we demonstrated two integrated processes for the direct synthesis of dodecanol or 2,4,8‐trimethylnonane (a jet fuel range C12‐branched alkane) using methyl isobutyl ketone (MIBK) that can be derived from lignocellulose. The reactions were carried out in dual‐bed continuous flow reactors. In the first bed, MIBK was selectively converted to a mixture of C12 alcohol and ketone. Over
    首次,我们展示了使用可以衍生自木质纤维素的甲基异丁基酮(MIBK)直接合成十二烷醇或2,4,8-三甲基壬烷(喷气燃料C 12支链烷烃)的两种集成工艺。反应在双床连续流反应器中进行。在第一床中,将MIBK选择性转化为C 12醇和酮的混合物。在Pd改性的镁铝水滑石(Pd-MgAl-HT)催化剂上,在温和的条件下可以实现较高的C 12含氧化合物总碳收率(73.0%)。在第二张床上,C 12在第一个床中生成的含氧化合物在Ru / C催化剂上氢化为十二烷醇,或在Cu / SiO 2催化剂上加氢脱氧为2,4,8-三甲基壬烷。如此获得的十二烷醇可用作十二烷基硫酸钠(SDS)和十二烷基苯磺酸钠(SDBS)的生产原料,它们被广泛用作表面活性剂或清洁剂。所获得的2,4,8-三甲基壬烷无需加氢异构化即可掺入常规喷气燃料中。

    日期:1946.8
    IN connexion with the communication on this subject by Hickinbottom and Schlüchterer1, we think it would be of general interest to record similar observations made in and since June 1945 in the course of work on hydrocarbon syntheses for the Institute of Petroleum.
    关于 Hickinbottom 和 Schl¼chterer1 就这一主题所做的交流,我们认为,记录下 1945 年 6 月及以后在为石油研究所进行碳氢化合物合成工作期间所做的类似观察,将具有普遍意义。
