查询词典 modulator-demodulator

In the basis of comparing the developing projects on the optical interconnection networks, combining with the actual probability of realization, we proposed the scheme of free space optical crossbar interconnection network using spatial light modulator . This interconnect structure is the most powerful single level interconnect network with the characteristics of reconfiguration and non-blocking. It can achieve arbitrary point-to-point link. Even more has it the ability of broadcasting and funnelling.

It is one of the key pathogeneses of postmenapausal osteoporosis that estrogen deficiency leads to the decrease of OPG、TGFβ expression and the increasing expression of some bone-resorbing cytokines as OPGL、M-CSF and TRAIL, then stimulates osteoclast differentiation and activity, which potentiates bone resorption and bone loss:(2) ICI182780 shows partial transactivating function in osteoblasts, so it should belong to a kind of selective estrogen receptor modulators .

雌激素缺乏可能导致HOB中OPG、TGFβ的表达减少，而解除了对OPGL、M-CSF和TRAIL等刺激OC生成和活化的细胞因子的抑制作用，OC的数量和活性增加，导致骨吸收增强和骨量丢失，这是导致绝经后骨质疏松症的一个重要的发病机制；ICI182780在成骨细胞内表现出促转录活性，因此它并非纯ER拮抗剂，而应属于选择性雌激素受体调节剂(selective estrogen receptor modulator，SERM)。
