The molecule of antibacterial peptide displays α-helical structure of amphipathicity, which can form the ion-channel to induce the death of pathogen on the protoplasmic membrane of bacterium, eumycete and parasite.

抗菌肽分子呈双亲性的α-螺旋结构可使细菌、真菌、寄生虫的质膜形成离子通道，从而导致这些病原体死亡。

No extrarenal arterial blood supply of renal m alignancy was found in 74 patients, including 41 patients with and 33 patients without the renal capsule breakthrough with m alignancy.

对116例肾恶性肿瘤患者行多层螺旋CT增强扫描，分析其肾外供血动脉的特征及形成机制。

The Filicales is much the largest living group of ferns, and they normally have large spirally arranged leaflike fronds derived from lateral branches of the main axis, some or all of which bear sporangia on their margins or undersurfaces.

薄囊蕨纲是现存蕨类植物中数量最多的一个类群，他们通常具有很大的、螺旋状排列的、从主轴的侧枝上形成的叶（巨型叶 MEGAPHYLIS ），其中一部分或绝大多数都是在叶边缘或背面产生孢子囊群。

O After making this contact, have these people in their DNA 6,8 and also 10 helices.

o 这个接触形成之后，这些人就有他们的第6，8和也有第10个 DNA 螺旋。

Other helices can be formed by bringing together two or more individual helical strands.

其他螺旋可以由带来两个或多个各自的螺线子线形成。

Reaction of the ligand with CdI2 or Cu(NO3)2 afforded dinuclear monohelical complexes 1 and 2 equipped with the aromatic rings, and the complex interacted each other through cooperative C-H...π and π...π interactions to form homochiral 2D layer along ab plane.

配体与CdI2和Cu(NO3)2反应得到双核单螺旋化合物1和2，在化合物2中，由于C-H…π和π…π的协同相互作用沿ab面形成单一手性的二维平面。

Both three-dimensional chiral compounds have intriguing chiral channels, which are built up of homochiral intertwined double helices. The circular dichroism spectra of 1 and 2 in water have shown they are stable in solution, which document they will be significantly useful in asymmetric catalysis and chiral medicine.

以Keggin结构多金属氧酸盐为建筑单元，通过手性的铜-脯氨酸配合物作为模板剂构筑了2个基于Keggin结构多金属氧酸盐的3D纯手性化合物，化合物1和2是一对对映体，代表了世界上第一例3D手性多酸化合物，具有由同手性螺旋缠绕形成的手性孔道，水溶液中的圆二色谱表征这个3D手性化合物可稳定存在，显示这个物种可以在不对称催化及手性药物方面有潜在的巨大的应用价值。
