The effects of cysteamine ( cs ) and chromium yeast ( cry ) on growth performance , serum metabolites , and lipid metabolism were studied in growing swine 本研究探讨了半胱胺和酵母铬对仔猪和生长猪的生产性能、脂类代谢及神经内分泌的影响。
Transportation and based on chemical professing factory . we had a set of product line of annual productive sulfur bearing acerbity 100 thousand tons and a set of cysteamine hydrochloride line of annual productive dimethyl 我厂有年产10万吨硫磺制酸生产线一套，年产1500吨半胱胺盐酸盐及年产5000吨硫酸二甲酯生产线各一套，年产3000吨合成蒽醌和年产800吨二乙基蒽醌生产线各一
Rob van dam , a harvard scientist and the lead author of the journal of the american medical a ociation review , acknowledged that caffeine could increase blood pre ure and slightly increase levels of the amino acid homocysteine , po ibly raising the risk for heart disease 《美国医学会杂志》评论的主要作者哈佛大学科学家罗布?范?达姆承认，开咖啡因可能会增加血压并能轻微增加高半胱胺酸的水平，这可能会增加心脏病的发病风险。

A novel protein immobilization approach for piezoelectric immunosensors based on the sam of derivative aa has been proposed , which is formed by coupling merca ptoprorionic acid ( mpa ) to alginic acid sodium salt via edc and nhs . ( 1 ) the tr antibody is immobilized via edc and nhs . comparing with the mpa sam method , this new approach shows greater frequency response and high sensitivity 应用edc和nhs使褐藻酸钠与胱胺偶合形成衍生褐藻酸钠作新的自组装材料，用于蛋白固定，应用这一新方法， ( 1 )实现了转铁蛋白抗体分子的固定，并对转铁蛋白参考血清进行了测定，该方法可在0 . 08 25 . 7 g / ml范围内对转铁蛋白进行测定。
The main work is introcuced as follows : ( 1 ) the inorganic - organic nanocomposite of nanogold and chitosan , which have high biocompatibility , was synthesized in situ and used for the immobilization of antibodies . an amplified piezoelectric immunosensor for detection of normal human igg was designed with this nanocomposite film . comparing with self - assembling film of semi - cystamine , the inorganic - organic nanocomposite film could immobilize more antibodies with the activity of antibodis well retained 与半胱胺自组装膜比较,纳米金-壳聚糖复合物膜较大的比表面积使其可固载更多的抗体,同时可较好地保持抗体的反应活性;纳米金的物理吸附作用使更多的沉淀结合于石英晶体表面,以其为载体制备的传感器具有更大的频率响应值。
