Ii analysis of veterinary drug residues in raw milk . testing parameters include aminoglycosides , - lactams , macrolides , polypeptides , quinolones , sulfonamides , tetracyclines , lincomycin , spectinomycin , trimethoprim , chloramphenicol and synthetic hormones . the laboratory maintains its accreditation status on the tests for pesticide residues in vegetables and veterinary drug residues in milk under the hong kong laboratory accreditation scheme Ii测试未经加工的奶类所含残馀兽药，包括是否含有氨基糖类类药物-内胺类药物大环内脂类药物多类药物诺酮类药物磺胺类药物四环素类药物林可霉素大观霉素甲氧苄氨嘧啶氯霉素和人造激素。
Large numbers of evidences indicate that isoflavones prevent and cure cardiovascular diseases through influencing lipid metabolism , anti - oxidation of low - density lipoprotein and lipid peroxidation , affecting vascular smooth muscle cell and blood vessel compliance , inducing anti - thrombotic effect , as well as influencing the expression of atherosclerosis related gene 大量研究表明，大量与黄酮通过对脂类代谢的影响、抗低密度脂蛋白氧化及脂质过氧化作用、对血管平滑肌细胞和血管顺应性的作用、抗血栓生成作用、对动脉粥样硬化相关基因表达影响等方面，来预防和治疗心血管疾病。
By compressing a monolayer film , the coexistence of liquid condensed ( lc ) and liquid expanded ( le ) phases can be reached . the transition from le to lc is usually regarded as a first - order one , so the theory of crystallization can be applied . in this article we review our recent studies on the growth of lc domains in the le - lc coexistence region driven by the illumination of a fluorescent microscope . the mechanism of this unusual 2d domain growth phenomenon is discussed . the formation of faceted , dendritic and fractal - like domains as well as the evolution and the transition of these patterns are investigated 当处于气液界面的类脂类化合物的单分子膜被压缩时,随着分子间距的缩小,单分子膜将经历一系列相变过程.通过荧光显微术可以观测到新相的成核和生长过程.由于单分子膜的二维特性,该系统中的实验观测对于检验和发展二维界面生长理论尤为重要.本文总结了近年来本课题组与相关单位合作,在单分子膜系统中发现的实验现象以及对其生长机制的系列研究.内容包括对单分子膜系统中的成核、界面稳定性、枝晶生长、形态演变等的观测和分析

Apolipoprotein e , a 34kda protein composed of 299 amino acids , is a multifunctional molecular , which is an important functional component of chylomicrons and very low density lipoprotein , intermediate density lipoprotein and high density lipoproteins . as a ligand for the low density lipoprotein receptor ( ldlr ) , it plays an important role in the metabolism of plasma lipoproteins 载脂蛋白e ( apoe )是34kda大小的多功能分子，由299个氨基酸组成，是cm 、 vldl 、 idl和部分hdl的组分，通过ldl受体途径调控脂蛋白代谢，在脂类代谢中发挥重要作用。
Testing parameters include aminoglycosides , - lactams , macrolides , polypeptides , quinolones , sulfonamides , tetracyclines , lincomycin , spectinomycin , trimethoprim and chloramphenicol . in august 2004 , the hong kong accreditation services made a re - assessment visit to the man kam to food laboratory . the laboratory succeeded in re - affirming its accreditation status and extending its accreditation scope to cover the testing of vegetables and milk for more pesticide residues and veterinary drug residues respectively , under the hong kong laboratory accreditation scheme hoklas Ii测试未经加工的奶类所含残馀兽药，包括是否含有氨基糖类类药物-内胺类药物大环内脂类药物多类药物诺酮类药物磺胺类药物四环素类药物林可霉素大观霉素甲氧苄氨嘧啶和氯霉素。
Bsp ( boyine seminal plasma ) protein is the cardinal protein in bovine sperm , which can combine with choline or phosphycholine and then adhere to the surface of sperm to promote the sperm capacitation induced by heparin and high density lipoproteins ( hdl ) . moreover , bsp protein can combine with heterogeneous collagen , fibrinogen , heparin , calmoduline , igf - ii and apoa - i . bsp can also inhibit the migration of cholesterol on the sperm membrane 前言bsp ( bovineseminalplasma )蛋白是牛精浆中的主要蛋白质， bsp蛋白可以与胆碱或磷脂胆碱结合，黏附于精子表面，可促进由肝素、 hdl等诱导的获能过程，另外bsp蛋白与不同来源的胶原、纤维蛋白原、肝素、钙调蛋白、 igf - 、 apoa -等结合， bsp蛋白还可抑制精子胞膜上的胆固醇迁移，这些都暗示了bsp蛋白在精子胞膜的脂类代谢及调节精子的获能以及顶体反应方面发挥重要作用。
