HypoxiaInducibleFactorintheCardiovascularSystem
Hypoxia (or low O2 levels) affects various pathologies. First, tissue ischemia, a variation in O2 tension caused by hypoxia/reoxygenation, can lead to endothelial cell changes. For example, long periods of ischemia result in endothelial changes, such as vascular leakage, resulting in varicose veins. In more severe situations, ischemia can lead to myocardial or cerebral infarction and retinal vessel occlusion. Of inte......阅读全文

Rf值－(retention－factor)
Rf值 (retention factor)对于确定的固定相，混合物样品中不同的化合物在层析板上爬升的速度不同，这是由于它们对于固定相的吸附能力不同，对于洗脱剂的溶解能力也不同。改变不同的洗脱溶剂，或用不同溶剂配成混合洗脱剂，化合物的分离效果可自行调节。组分在板上的分离情况一般用比移值（Rf）的大小
