Tetrabromocinnamic Acid (TBCA) is a new class of specific protein kinase CK2 inhibitors [1].
Protein kinases have been involved in catalyzing the phosphorylation of serine, threonine and tyrosine residues in protein substrates that play dominant roles in controlling nearly all cellular functions. The Ser/Thr-specific protein kinase CK2 has been implicated in signal transduction, gene expression, DNA repair, RNA and protein synthesis. CK2 is invariably elevated in a wide spectrum of tumours [1].
In vitro: TBCA was a selective, cell-permeable inhibitor of CK2 with an IC50 of 0.11 μM. The Ki value was 77 nM. TBCA showed minimal effect on a panel of 28 other kinases. TBCA induced cell death in Jurkat adult T cell leukemia cells with an DC50 of 7.7 μM [1]. TBCA dose-dependently inhibited platelet aggregation and secretion induced by various agonists including 2-MeSADP, AYPGKF, SFLLRN, and CRP [2]. TBCA also significantly inhibited agonist-induced thromboxane A2 (TxA2) generation and ERK phosphorylation. TBCA significantly inhibited platelet spreading on immobilized fibrinogen surface and clot retraction mediated by integrin αIIbβ3 signaling [2].

我想咨询的是ELIX的处理柱(好象叫PRO-GUARD),多长时间换一次,我们这里在用水不是很大量的情况下半年就不行了,总是提示低压报警,现在刚换了三个月,又开始报警了,是否我们这里水质极差还是机器有问题?
该怎么解决呢,一个柱子近3000大洋,太贵了,还不如直接买纯净水划的来
主要看你具体的需要,
适合你的才是最好的。
纯水机是属于科学仪器,用途在于实验室科研,工艺技术相较于净水器复杂很多,设备所用的组件和耗材也比净水器多,原则上可以说:净水器的超级升级版就是纯水机。
水中的杂质有微小颗粒、无机离子(钙离子、钠离子、镁离子等)、微生物(内毒素、热原)、弱电解质、有机物。
净水器是将水中的有害物质(污染物)净化成可直接饮用的水,但是水中仍有较多的无机离子和部分有机物,这对人体无害,甚至可被人体吸收利用;纯水机又分为初级纯水机和超纯水机,力求纯化后只剩下水,不含其它任何物质。
净水器的工艺是:预处理-反渗透;
纯水机的工艺是:预处理-反渗透-紫外消毒-DI离子交换-超滤(若需要);
净水器售价在几千元即可,最高不超过一万;纯水器可由近万元至十多万。
好?急盼提供建议,多谢多谢!
功能:过虑掉自来水中所有物质,出来的水是纯净水,如果需要和矿泉水,可以单加一个麦饭石,这样出来的就是矿物质比较丰富的矿泉水了,当然,这样的矿泉水肯定比净水机出来的可以生饮的水好,净水机出来的水虽然有矿物质,但是只是自来水含有的,很多矿物质是自来水无法提供的。一句话:纯水机出来的水相当于外面卖的瓶装的纯净水,如果加上麦饭石,相当于卖的矿泉水;至于净水机,出来的水是有部分自来水中矿物质的可以生饮的净化水。
特点:有电机,需要电源,有储水罐,一般为五级过滤,第一级为滤芯,第二和第三级为活性炭,第四级为用于宇航技术的RO逆渗透膜(此为核心),第五级为精致活性炭,主要用于改善口感。可加第六级放置麦饭石。
净水机:
功能:能够过滤掉自来水氯、杂质等,最后出来的水能够达到生饮的标准,保留了自来水中的对人体有用的矿物质;
特点:没有电机,不需要电源,靠水压驱动过滤。没有储水罐,一般为五级过滤,第一级为滤芯,第二和第三级为活性炭,第四级为中空丝膜或陶瓷过滤,第五级为精致活性炭,主要用于改善口感。
直饮机
管道直饮机,是在饮水机的基础功能上增加进水自动控制器,使用时只需将管道直饮机与饮用水管道直接联接,实现自动进水,可直接饮用的饮水机。是现代住宅小区、写字楼供水的终端饮水设备。
