Multivariate analysis considering caveolin-1 immunoreactivity in addition to the established prognostic parameters such as pT stage, pN in these patients confirmed that caveolin-1 is an independent functional predictor of poor survival. We further revealed that up-regulated caveolin-1 in CL cells is necessary for mediating filopodia formation which may enhance the invasive ability of lung adenocarcinoma cells.

利用多变数分析的方法分析Caveolin-1及其他已知会影响预后的变数，例如肿瘤大小及淋巴结转移状况等，证实Caveolin-1的确是影响预后的独立变数，最后我们发现Caveolin-1会引起肺腺癌细胞产生伪足，这可能是Caveolin-1造成癌细胞侵袭性增加的原因。

It is thought that the mechanism behind excess nutrients affecting the reefs is due to increased light and oxygen competition from algae,[9] but unless herbivory is unusually low, this will not create a phase shift from the Great Barrier Reef being primarily made up of coral to being primarily made up of algae.

有人认为，珊瑚之所以受到了营养物质过剩的影响，背后的原因是海藻导致了光照和氧气竞争的加剧。除非植食生物出现异常性减少，大堡礁的珊瑚被海藻所替代的情况就不可能出现。

A number of key findings can be identified:(1) Planned behavior in the form of saving points towards some particular redemption goal is common and acts as a motivator to continue purchasing with the retailer;(2) Attainment of these specific goals, however, is less likely due to a variety of intercepting events (Soman, 1998), including goalswitching and impulse redemption
