NF-κB is a kind of important nuclear factors which are relative to lots of cellular activities such as activation of immunocyte, development of T and B lymphocyte, stress reaction, cell apoptosis and so on. NF-κB exists in almost all types of cytoplasm in the unreactive form of heterodimer or homodimer.

核转录因子κB(nuclear transcription factorκB， NF-κB)是一类关键性的核转录因子，通常以同源或异源二聚体非活性形式存在于几乎所有类型细胞的胞质，其与免疫细胞的活化，T，B淋巴细胞的发育，应激性反应，细胞凋亡等多种细胞活动有关。

Its insecticidal active ingredients are sesquiterpenoid polyol esters with a dihydroagarofuran structure. These compounds are stable to light, heat, and pH, and exert a narcotic and toxic poisoning action. Celastrus angulatus contains a plant-origin insecticide with a unique mechanism of action. Celangulins, a 0.2% emulsifiable concentrate has already been developed for insect control.

On his return to Capernaum the collectors of the temple tax (a didrachma, half a sacred shekel), which every Israelite of twenty years old and upwards had to pay (Ex. 30:15), came to Peter and reminded him that Jesus had not paid it Matt.

在他返回罗马收集的庙税（ 1 didrachma ，有一半的神圣谢克尔），其中每一个以色列人的二十年岁以上的已支付（例如30：15 ），来到黄匡源，并提醒他说，耶稣没有支付它

TGF-βbinds to a heteromeric complex of type I and type II receptors. The constitutively active type II receptor phosphorylates and activates the type I receptor which phosphorylates Smad2 and Smad3 (receptor-associated Smads). Receptor-associated Smads bind the common mediator Smad4 and are translocated to the nucleus, where they associate with DNA-binding cofactors to modulategene transcription.

TGF-β与其效应细胞表面的Ⅱ型受体TβRⅡ和Ⅰ型受体TβRⅠ形成的异源二聚体结合，相继激活TβRⅡ和TβRⅠ，活化的TβRⅠ再进一步活化Smad2和Smad3，磷酸化的Smad2/3必须与Smad4结合形成复合物，才能进入细胞核，调节靶基因的转录[6]。

Today (it shall, 1698), from Manchuria Yan Lassan Khutuktu preach,"photo category learning","kosa theory" and "solemn theory" and "meso-Mahayana theory" taught in a multi-Kang area 4 on the and its commentaries, with the upper and lower density homes the same teachings, but also self-cultivation Xianmi two laws, there are 500 monks, but also the three major monasteries of the wave rather Kang village monk the source.

现今（应即1698年），由满洲颜拉散呼图克图宣讲《摄类学》、《俱舍论》、《庄严论》和《中观大乘论》，在多康地区讲授的四论及其注疏，与上下密院的教法相同，而且修行显密二法，有五百名僧人，同时也是三大寺的波颇康村的僧源。

Areas with relatively stable tectonic settings and well preservation conditions,such as Sichuan basin,are characterized by multiple sources,early accumulation,oil-gas conversion,and late finalization;the Middle and Lower Yangtze areas overlain by Mesozoic and Cenozoic strata are characterized by secondary hydrocarbon generation and late re-(servoiring;) while the areas with outcropping carbonates,such as western Hunan and Hubei and Yunnan-Guangxi-Guizhou regions,are characterized by early hydrocarbon generation and late destruction and reformation.
