The cation radical film exhibits an ageing effect, i.e. the changes in the physical or chemical properties of the film with time, following its deposition. It was found that because of a strong intermolecular interaction, ageing effect resulted in different aggregation states of cation radicals in the deposited film, and the film lost its reoxidation activity.

The Hedgehog morphogen governs cell differentiation and proliferation in a diverse array of patterning events in many animal species, ranging from insects to mammals. The seven-transmembrane protein Smoothened transduces the HH signal across the plasma membrane but molecular mechanisms of its activation are poorly understood. Zhao et al .

Hedgehog形态发生素在从昆虫到哺乳动物在内的很多不同动物物种的各种不同成形事件中决定细胞的分化和增殖。7-跨膜蛋白Smo跨越胞质膜传导Hh信号，但科学家对Smo激发的分子机制却很不了解。

Almost all CF was released from Dansyl-PE by CTX-IX that osmosed the Dansyl-PE liposome like detergent; CF releases from PE or PS liposome induced by CTX-IX were related with both of CTX-IX and phospholipid concentrations, this indicated that the phase seperation should be a reasonable mechanism for CF permeability of PS or PE liposome in the presence of CTX-IX rather than CTX-IX channel formation on the membrane. CTX-IX influence of CF release of PC liposome was very slight. CF release from Dansyl-PE、PE or PE liposome in response to CTX-IX could be inhibited by Ca〓.

CTX-IX对靶脂如此种种强烈的作用，使得它引起含Dansyl-PE脂质体CF的泄漏犹如击污剂那样强烈；引起含PS或PE脂质体CF渗透的增加为一个与CTX-IX及磷脂浓度有关的二级反应过程，这种动力学特征提示渗透性增加的机制可能是CTX-IX在脂膜上产生的脂质分子相分离，而不是CTX-IX脂膜上形成通道；CTX-IX对PC脂质体渗透性几乎没有影响，而对上述脂质体渗透性增加作用均可被Ca〓所抑制。

The gene launches a biochemical process in which a molecule called plasmin perforates the membranes of tissues, causing the membranes to break down and allowing the cancer cells to escape into the bloodstream and to adjacent tissues.
