Background – The caninised monoclonal antibody lokivetmab (LKV), directed at interleukin (IL)‐31, is very effective at controlling pruritus in most dogs with atopic dermatitis (AD). However, evidence exists that IL‐31 is not required for the induction of acute allergic skin inflammation, which might explain why this treatment is less efficacious in ...

Factors that shape large‐scale gradients in clonality
Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

General‐purpose genotypes and evolution of higher plasticity in clonality underlie knotweed invasion
Summary Many widespread invasive plant species express high phenotypic variation across novel environments, providing a unique opportunity to examine ecological and evolutionary dynamics under global change. However, studies often lack information about the origin of introduced populations, limiting our understanding of post‐introduction evolution.

Long‐term use of lokivetmab in dogs with atopic dermatitis
Background – Lokivetmab, a caninised monoclonal antibody against interleukin (IL)‐31, is an effective treatment for the pruritus associated with canine atopic dermatitis (cAD). Objectives – To investigate the efficacy and safety of lokivetmab during long‐term treatment defined as at least three consecutive lokivetmab injections in atopic dogs under ...

【目的】构建人瘦素基因 cDNA 克隆, 并进行序列分析。【方法】用逆转录聚合酶链反应扩增人瘦素基因 cDNA , 获得片段( 640 bp)连接至 pUC19 载体, 并转化大肠杆菌 DH5α。以末端终止法进行序列测定。【结果】所克隆的人瘦素 cDNA 含全长的人瘦素基因编码区,仅 287 位的腺苷酸被鸟苷酸代替, 导致 96 位编码谷氨酰胺的密码子 CAA 改变为编码精氨酸的 CGA, 其意义尚待阐明。【结论】以逆转录聚合酶链反应方法成功地构建了人瘦素基因 cDNA 克隆。

根据GenBank上已发表的H6N2亚型的非结构蛋白基因(NS)序列,设计一对特异性引物,成功从本实验室分离、保存的H6N2禽流感病毒分离株A/Mallard/SanJiang/151/06(H6N2)中克隆到NS基因序列。该克隆基因全长860bp,编码NS1和NS2两种非结构蛋白,与其他H6N2亚型的NS基因进行同源性比较,同源性为71.1%~97.2%,推导的氨基酸序列同源性为62.0%~94.6%。
