比如说prion disease 类别的疯牛病,Creutzfeldt-Jakob Disease ,scrapie disease,
以及Yeast里面类似的prion propagation,就是现在难以解释的,这些病症仅仅需要引起
病症的蛋白聚合体被吞食.比如说CJD就是小岛土著的风俗中食用死者的尸体引起的.几

沾染了疯牛病人的手术器械而被传染疯牛病的,而那手术器械是经过巴斯德消毒过的.
我赞成对转基因食物的警惕,虽然有可能它不具有威胁,但如果真的有危险,这可能是种

瞎扯旦,这一系列文章都谁写的?
Galileo incorrectly stated in 1638 in his
Two New Sciences that this curve was an arc
of a circle. Johann Bernoulli solved the
problem (by reference to the previously
analysed tautochrone curve) before posing
it to readers of Acta Eruditorum in June
1696. Four mathematicians responded with
solutions: Isaac Newton, Jakob Bernoulli
(Johann's brother), Gottfried Leibniz and
Guillaume de l'Hopital. Three of the
solutions (excluding l'Hopital's) were
published in the May 1697 edition |

wrong.
"When confronted with a MRI pattern showing bilateral basal
ganglia lesions, the differential diagnosis includes hypoxic injury
[6], mitochondrial disease [7], vasculitis [8], carbon monoxide
intoxication [9], hypoglycemia [10], extrapontinemyelinolysis [11],
Wilson’s disease [12], Creutzfeldt–Jakob disease [13], and deep
venous thrombosis [14]."
So I guess deep venous thrombosis, and I guess lacunar stroke.

Very nice! What is the diagnosis?
As a physician, the most important thing is that you try to get the history
and do physical by yourself. |

发帖数: 372 | 18 上一章我们谈了十六世纪宗教改革的一些变化，我但要再次强调宗教改革基本上是教
义的改革，而非生活方式的改革。在宗教改革的两侧，出现四个运动实际影响宗教改革之
落实。十六世纪末的亚仁特（Johann Arndt）是德国敬虔主义的先驱，其后继人乃史宾
纳（Phi- lipp Jakob Spener）和法兰克（August Hermann Francke）。敬虔主义把
宗教改革带到德国的草根阶层，所以，这个运动亦可说是神子民的改革运动。与此同时，
英国出现了清教徒运动，进一步扩大落实改革的教义。英国人中有不少信徒开始追求过圣
洁的生活。英国在十八世纪还有一个注重灵命更新的循道主义运动。十八世纪末和十九世
纪初的福音派运动，可算是第四个更新的运动。以上四个更新运动的基础都在于宗教改革
的教义。但在这本书，我只会谈英国清教徒运动的兴起，它的重要性和传奇性，以及对我
们的影响。
清教徒运动的兴起
按照福音派的传统，清教徒运动常被描述为福音派的修院主义运动。但所指的不是这
些人在过修院制度式的生活，而是说他们比任何其他传统的改革派信徒更认真地过圣洁的
生活。这种态度是今天我们福音派的人所缺乏的。我们 |
