Food that are high in purines include:
Red meat
Animal organs, such as liver, kidney, brain
Other meat, such as bacon, veal, venison, and turkey
Fish, especially mackerel, herring, sardines, codfish, trout, haddock, and
anchovies
Shellfish, such as scallops and mussels

precision medicine (PM) 主要的aim就是通过genomic/genetic analysis来 帮助
临床诊断, 临床治疗指南,推动 靶向治疗药物的研发。 PM有希望 完全改变临床 癌
症诊断 和 治疗的指南。
接下来的20年,NIH NCI 会往PM里面扔很多钱,估计PI们来申请 PM相关的科研,主要
的目的可能会有几个方向:
1. 哪些突变 容易引起某系癌症? (如同bmwcar说的)但是,这个领域,已经基本上
被挖光了。。。 类似BCL-ABL 的 determinant gene 导致 的 癌症,估计已经发现的
差不多了 (BRCA,VHL,BCL-ABL, NF1, NF2,........ 一大堆)。

Purines - 嘌呤
Gout - 痛风
Uric acid - 尿酸。
痛风是尿酸代谢疾病。尿酸是嘌呤代谢产物。一般人可以把尿酸排掉。
但是一些人无法排掉。就是痛风。
痛风的人要少吃嘌呤
很多健康食物有不少嘌呤. 包括海鲜,鱼类,肉类,菜花,豆类,蘑菇,燕麦.
that most of the purine-containing foods included within the World's
Healthiest Foods - asparagus, cauliflower, chicken, kidney beans, lima beans
, mushrooms, navy beans, oatmeal, peas salmon, spinach, and tuna
所以没有必要考虑嘌呤过多. 对一般人.this is the bottom line

尿酸当然跟purine有关,是purine的代谢产物
事实上,痛风就是尿酸的析出结晶引发组织炎症

鱼子酱含有丰富的营养成份,如蛋白质、脂肪、维生素,另外含有淋巴糅和维生素
B3酸,具有非常显著的保健作用,是许多人的大爱。但你知道吗?鱼子酱大量食用会引
起痛风的。今天小于老师就来告诉你为什么,还有哪些食物也会让人得痛风呢?
痛风的由来
首先我们了解一下痛风的由来。痛风是众多“富贵病”中的典型代表,在物质匮乏
年代是很少出现痛风的。本质上来说,痛风是一种嘌呤(purine)代谢出现异常导致的一
种晶体性关节炎,少数人是因基因缺陷而出现的遗传性疾病,更多的人是过度饮食所致
,也就是吃出来的病。痛风常伴随着腹型肥胖、高脂血症、高血压、2型糖尿病及心血
管病等表现,并且发病呈年轻化趋势。
鱼子酱为什么会让人得痛风
鱼子酱中的嘌呤含量极高,可以说高的变态,平均值为140mg/100g,属于嘌呤含量
非常高的一类食物。适当的嘌呤摄入,人体完全可以接受,并转化为尿酸排出体外;但
如果摄入量过高,就会造成代谢出来的尿酸无法在短时间排出体外,从而在体内大量蓄
积,出现尿酸盐结晶,时间长了,这些结晶就会游走到肢体的最末端,造成晶体性关节
炎,影响... 阅读全帖 |

p***n 发帖数: 17190 | 13 這個我有研究過一點點
關鍵在水
水是 HOH
然後是碳
COH
COH 接在一起就是糖
purine pyrimidine
是碳氮合
碳好說話
要抓氮就得雙鍵不然氮不開心會兩個氮跑掉自己開小灶
胺基酸
則是氮碳合加上水的-OH
所以一切的關鍵
是水

现在号称较健康的是 grass fed, organic, natural, 前2者好像是FDA regulate
后者有漏洞, 有的就是在屠宰前放到外面一两天
关于uric acid 我也不是很明白, 大概记得是purine 转化的, 有没有明白的说说?

cholesterol测到过健康值的下限。注意,cholesterol是身体必须的,如果低于下限
就是不健康的.事实上美国很多严格执行low fat diet plan的妇女胆固醇缺乏

跟ketone bodies没关系
跟海鲜和肉有关
这个跟结石一样,是high protein intake的潜在风险
只不过原文拍也拍错了位置,跟ketone bodies扯到一起去了
我现在其实一天40%的蛋白是来自whey protein

According to traditional Chinese medical theory, acupuncture points are
situated on meridians along which qi, the vital energy, flows. However, I

b*****h 发帖数: 783 | 34 1. INHX is over-valued with cap near 1B.
its major pipeline INX-189 is a purine nucleotide, which is in the same
class as VRUS's PSI-938.
It is not necessary to predict the same side effect of INX-189, but as PSI-
938 has shown bad sign of liver function, the risk of INX-189 sharing the
similar profile is increased.
2. Gilead's deal is not 100% sure thing, if Gilead turn off the deal, INHX
will also suffer.
not worth of taking huge risk to bet small profit..
