Moreover, the hybridization of PNA to DNA and RNA oligomers is uncompromised or even improved sequence selective.

肽核酸与双螺旋DNA更易形成三螺旋的另一个重要的特性是肽核酸与双螺旋结合时对序列的选择性非但没有降低反而有所升高。

In order to further investigate the relationship of SP and ESCs, we design two level experiments —in vitro and in vivo. In vivo, firstly, We establish the nomal rat full-thickness wounds model, and employ integrin β1 keratin 19(K19)、 keratin 15(K15)、 Brdu as ESCs markers to conform the existence of ESCs in the granulation tissue of Group Capsaicin (rats were subcutaneously injected capsaicin pre-injury to damage sensory neuron and block the secretion of neuropeptides), Group Control, and Group SP (rats were injected SP in the wound postinjury). Secondly, as diabetic skin lacking of SP due to extensive pathological changes of sensory ending, we make a hypothesis:one of the main reason of unhealing wounds on diabetic patients could be insufficient SP which lead to fewer ESCs recruitment around wounds.

在此基础上，为进一步验证P物质促进表皮干细胞向肉芽组织中募集这一重要发现，本研究首先利用β1整合素、K19、K15等干细胞标记物以及干细胞慢周期性的特点，分别在体观察了正常皮肤伤口愈合过程中SP组、辣椒素组采用特异性感觉神经毒性药物辣椒素(capsaicin皮下预注射化学性除去感觉神经从而阻止神经肽分泌、对照组肉芽组织中表皮干细胞分布特点；其次，糖尿病患者皮肤存在周围末梢神经的损伤和神经肽含量的下降，这是否会导致糖尿病皮肤伤口创缘表皮干细胞募集不足，继发伤口难愈？

Attenuation The trp operon is also controlled by attenuation A leader sequence in the polycistronic mRNA upsteam of the coding region of the trpE structural gene encodes a 14 amino acid leader peptide including two tryptophan residues The RNA leader sequence can for several possible stem-loop secondary structures,one of which can act as a transcription terminator whilst a different stem-loop can act as an anti-terminator.

弱化作用 trp 操纵子也受到弱化作用的调控。在trpE结构基因编码区上游的多顺反子mRAN上有一段前导序列，可以编码一个含有14个氨基酸的前导肽，此肽中含有两个色氨酸残基。

Although it has been considered that this effect is due to an inhibition of the release of vasodilatory peptides, recent studies suggest that octreotide has a local vasoconstrictive effect.

虽然有认为这种效应是由于抑制了扩血管肽的释放，但最近的研究显示奥曲肽有局部缩血管效应。

As angiotensin II has a potent vasoconstrictive action, while bradykinin is a vasodilator, the reduced formation of angiotensin II and the inhibition of bradykinin breakdown leads to vasodilation.

由于血管紧张素Ⅱ有一个强有力的血管收缩的行动，而缓激肽是一种血管扩张，减少对血管紧张素 II 和形成的抑制缓激肽破裂导致血管扩张。

The sensory,sympathetic and parasympathetic systems are involved in the development of migraine, there are changes of many kinds of neuropeptides levels relating to vasomotion, and with relative changes of parts endogenous opiate peptides in this disease,and the lowering of β-EP.

结论感觉、交感及副交感神经系统均参与偏头痛的发病，在此过程中有多种与血管舒缩有关的肽类含量改变，同时伴有部分内源性阿片肽的相关变化及β-EP的降低。

The cDNA squence of antibiotic, an antibacterial peptide, a process for preparing the said cDNA and a process for recombining the antibacterial peptide are disclosed. The present frequency of amino acid codens in Attacin A cDNA is analyzed. The high-frequency coden is introdued to its protein sequence to configure its cDNA sequence. The target gene is synthesized by chemical synthesis method or polymerase chain reaction.
