Influence of different processing technology on sialic acid content of edible bird's nest products

本文以毛燕为原料,研究浸泡、挑拣、高温灭菌等工艺流程处理后燕窝唾液酸含量的变化。采用LC-MS/MS检测分析燕窝中唾液酸种类,此外,测定了不同加; 工条件下燕窝产品唾液酸含量并分析加工条件对唾液酸含量的影响,进一步分析了唾液酸热稳定性。结果表明:燕窝中唾液酸仅由N-乙酰基神经氨酸(Neu5A; c)组成,经不同工艺条件处理后,Neu5Ac保留率均可高达95%以上,且Neu5Ac热稳定性好,不同情况下Neu5Ac含量无明显差异。说明燕窝经; 过上述加工处理后不会造成燕窝酸的大量流失,并且其受工艺条件变化影响小,燕窝加工产品可以很好地保存燕窝的营养价值,从而稳定发挥其营养功效,具有很高; 的消费价值。In this paper,raw edible bird's nest was used as raw material to study; the change of sialic acid content in edible bird's nest after processed; by technology such as soaking,picking and choosing and high temperature; sterilization.

Serosurveillance and the PCP-FMD

通过一次平衡法考察了pH、离子强度和溶剂介电常数对红壤吸附低分子量有机酸的影响。研究结果表明,随着溶液pH值的升高有机酸的吸附量降低,其中草酸和酒石酸的吸附量在pH3.5～5.0范围内随着pH值的升高而急剧下降,之后缓慢下降（pH5.0～7.0）。柠檬酸、酒石酸和苹果酸的吸附量在1～2mmol/L初始浓度范围内随着离子强度的增加没有明显变化,但在2～20mmol/L初始浓度范围内却随着离子强度的增加而增加。红壤对草酸、柠檬酸、酒石酸和苹果酸的吸附量均随着溶剂介电常数的减小而增加。当溶剂中含6%的乙醇时,草酸、柠檬酸、酒石酸和苹果酸的吸附量分别是对照（不含乙醇）的1.05、1.05、1.11和1.31倍

雷帕霉素衍生物对胰岛的毒性研究

目的探讨雷帕霉素及其衍生物依维莫司、地磷莫司、佐他莫司对胰岛的毒性作用。方法采用小鼠胰岛素瘤细胞(MIN6)作为体外研究胰岛细胞的对象,分别在含有依维莫司、地磷莫司、佐他莫司的培养基中孵育MIN6细胞48小时,通过Brdu检测细胞增殖、CCK8检测细胞活力、PI检测细胞周期、流式细胞术检测细胞凋亡以及ELISA检测细胞分泌胰岛素功能,观察3种雷帕霉素衍生物对MIN6细胞的影响。结果我们发现3种雷帕霉素衍生物均会对MIN6细胞的增殖和活力产生抑制作用。在细胞周期和凋亡实验中,与阴性对照组比较,3种衍生物对MIN6细胞的影响呈现抑制G1期向S期转变的趋势和促进细胞凋亡的趋势,但差异没有统计学意义。另外,3种衍生物与雷帕霉素一样,均可减少MIN6细胞分泌胰岛素,差异具有统计学意义。结论雷帕霉素及其衍生物依维莫司、地磷莫司、佐他莫司均对胰岛产生一定毒性。国家自然科学基金项目(31271038,81302546
