GMOs, or “genetically modified organisms,” are plants or animals created
through the gene splicing techniques of biotechnology (also called genetic
engineering, or GE). This experimental technology merges DNA from different
species, creating unstable combinations of plant, animal, bacterial and

Canola 油的迷思與真相
大約是十幾年前，市面上突然出現了一種新的烹飪油，英文叫做 Canola Oil。起先只
有在專賣 ”健康自然產品” 的店裡才能看到，但是因為政府及私人公司都廣為宣傳這
種油的好處：純植物提煉、不飽和性脂肪、低膽固醇、 比別的植物油還理想…云云。
既然連政府都這麼說，大概是不會錯 了；於是乎關心自己和家人健康的朋友，都紛紛
買回去做菜。它在北美洲的銷路直線上升，沒多久也引進了台灣。
但是，Canola 油 到底是什麼東西做的呢？其他的油都可以從名字望文生義：... 阅读全帖 |

热备份其实也不定要串联。但是主节点和次级之间一定要有一个ACID MQ。这个是必须
的。
为了保证partition resilience这个ACID MQ甚至可以跨DC。
我说了热备份其实也不定要串联。也可以用基于multicast的架构。
这个设计有其特殊性，就是上行和下行的流量可能差几个数量级。每天票就那么多张，
几千万的量级。但是查询和抢票请求可能有几十上百亿。但是只有抢到的票才会影响状
态。
ACID MQ保证了抢到的票的durability。MQ两端任何一端挂掉，都能按照顺序完全恢复
。hotstandby转换成primary也是借助ACID MQ恢复状态。
问题是，机器挂掉，是百八十年不遇的。真挂了，短暂几秒钟不能提供服务，没啥大不
了的。关键是，状态确实能够完全恢复。而且前端后端也能恢复。
再次强调。这个case有其特殊性。更像股票市场。每天qoute比真正的trade多成百上千
倍。 |

发帖数: 424 | 12 不是医生，只能提些建议。最好还是多咨询医生。
1. 保护孩子首先。
2. 从你描述的症状来看。应该是不能代谢长链脂肪酸, 没法beta-oxidation
LCHAD=Long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency
VLCAD=Very long-chain acyl-coenzyme A dehydrogenase deficiency
最后导致长链脂肪酸堆积，导致肝损伤，直至肝硬化。
3.避免长链脂肪酸。这类的疾病用Carnitine or MCT (medium chain triglycerides)
oil supplement.跳过长链脂肪酸代谢那一步(请尊医嘱)
4.我想应该是long chain FA氧化通路上的基因的mutation导致的。
Arnold W. Strauss, MD

我的目的是：定量植物中的Salicylic acid （SA）。用的 extraction internal

好，可是最近不知什么原因，原本单一漂亮的SA的峰变成了两个：一个大的，一个很小

个，一个大的和一个很小的。为什么会这么不稳定呢？如果是柱子的原因，那如何改良
柱子呢？我中间没有做什么来改变柱子啊！真是奇怪。谢谢大家了。 |

carboxylic acid基的碳混合体系里，硼酸是先跟水键和还是跟carboxylic acid基键和
？理论上，应该取决于什么物理参数来决定以上键合可能性？是否也取决于在酸处理后
的炭材料上的acidic site多少？如果有任何推荐的文献，也请给与帮助。 本人不是化

在工作中很多时候有些简称什么的让人摸不着头脑，在这希望和大家交流一下，要如何
学习这些"slang" ,在哪里能找到医院里常有的简称呢？
A banana bag is an intravenous nutritional supplement that commonly is
prescribed to hospital patients who have nutritional deficiencies or
chemical imbalances. It contains a liter of saline solution that includes a
10 milliliter ampoule of multivitamin injection (MVI); one milligram of

Abstract
Organoarsenic compounds, such as roxarsone (3-nitro-4-hydroxyphenylarsonic
acid, ROX) and p-arsanilic acid (ASA), are widely used as animal feed
additives, while animal wastes bearing these compounds are often used to
fertilize agricultural land, which can cause arsenic pollution of soil,
surface water, and groundwater. Determination of a number of inorganic and
organic arsenic species in a variety of enviro... 阅读全帖 |

REALLY? for REAL?
大家千萬别吃 Canola 油
大約是十幾年前，市面上突然出現了一種新的烹飪油，英文叫做Canola Oil。起先只有
在專賣”健康自然產品”的店裡才能看到，但是因為政府及私人公司都廣為宣傳這種油
的好處：純植物提煉、不飽和性脂肪、低膽固醇、比別的植物油還理想…云云。既然連
政府都這麼說，大概是不會錯了；於是乎關心自己和家人健康的朋友，都紛紛買回去做
菜。它在北美洲的銷路直線上升，沒多久也引進了台灣。
但是，Canola油到底是什麼東西做的呢？其他的油都可以從名字望文生義：如橄欖油，
當然是橄欖的油；花生油是花生仁的油；椰子油是椰子果實的油…等等。筆者心生疑惑
，查了極詳備的東華大辭典，竟然沒有這個字。
去年某日，筆者重聽雷博士在四、五年前演講的錄音帶，赫然得到了答案。正巧又有一
位琉璃光的朋友轉來一篇網上有關此油的文章，恰印證了雷博士所言。筆者知道有不少
朋友還在用這種油，當即轉發此文給一些能看英文的朋友。數天之後，有一位本地朋友
很急切的告訴我說：”好可怕啊！我們家這... 阅读全帖 |

http://en.wikipedia.org/wiki/Soybean_oil
Soybean oil has a relatively high proportion, 7–10%, of oxidation-prone
linolenic acid, which is an undesirable property for continuous service,
such as in a restaurant. In the early nineties, Iowa State University
developed soybean oil with 1% linolenic acid in the oil. Three companies,
Monsanto Company, DuPont/Bunge, and Asoyia in 2004 introduced low linolenic,
(C18:3; cis-9, cis-12, cis-15 octadecatrienoic acid) Roundup Ready soybeans

linolenic fatty acid is a healthy contributor for your hearts because it is
unsaturated,but it is not stable in a high temperature such as frying.
linolenic fatty acid 在高温下（油炸）会容易降解，和转化为trans-fatty acid,so
linolenic is not good for a frying oil in restaurants and food industries.
high linolenic soy oil was reduced to a low concentration by hydrogenation
to improve the quality for frying purpose. but this processing produced
saturated trans-fat. GM soybean frying oil contains low lin and |

活熊取胆迷思。
最近因为归真堂要IPO，之前沉寂了很久的归真堂活熊取胆的老底又被人翻了出来。动
物保护组织，爱护动物的人士，各种评论专家纷纷跳出来居高临下地抨击活熊取胆，从
各个方面证明活熊取胆不“熊”道。那么，事实真的如人们所说的一样吗？
第一、 这些抨击活熊取胆的人士一个最重要的论点是熊胆的主要成分是牛磺熊去氧
胆酸，而现在合成的纯品熊去氧胆酸很便宜，因此活熊取胆没有意义且很不人道。这个
观点看似正确，其实大谬。为什么这么说呢？我们从牛磺熊去氧胆酸的结构说起。牛磺
熊去氧胆酸是熊胆汁中一种特有的有效成分，有非常重要的药用作用，不仅能溶解胆结
石，有研究表明还能治疗帕金森氏症以及亨廷顿舞蹈症，以及保护中枢神经的作用。根
据熊种的不同，熊胆干粉含有47%-76%的牛磺熊去氧胆酸，少量的鹅去氧胆酸以及微量
