ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Selective Isolation, Identification and Biological Activity Investigation of Rare Actinomycetes from Rhizosphere Soil [PDF]
天然产物是新药制备的重要原料,绝大多数来源于微生物的天然产物都分离自放线菌,尤其是链霉菌。链霉菌是放线菌的重要组成成员,能合成结构类型丰富、生物活性多样的次级代谢产物,可用于创制抗生素、抗肿瘤药物、免疫抑制药物、抗虫药物等,在医疗、农业、食品等领域具有重要的应用价值。然而,随着对链霉菌持续的开发利用,目前从链霉菌中发现新型、高活性的次级代谢产物的几率在不断下降,来源于链霉菌的新药研发速度明显放缓。为了解决链霉菌活性次级代谢产物资源日趋枯竭的问题 ...

ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

The Role and Mechaninsm study of IL-20-related Cytokines contribute to Autoimmune Myocarditis in Mice [PDF]
目的:免疫相关因素与心肌炎引起的心肌纤维化密切相关。前期研究表明,IL-10家族成员在心肌炎慢性期心肌纤维化的形成过程中发挥重要作用。IL-20是最新发现的IL-10家族成员之一,具有调节细胞增殖和分化的作用。但IL-20是否参与心肌炎心肌纤维化过程尚不清楚。本课题通过实验探讨IL-20及其相关因子对小鼠自身免疫性心肌炎(EAM)心肌纤维化的影响及可能的分子调节机制。 方法:利用小鼠心肌肌球蛋白多肽MyHC6l4-629和完全弗氏佐剂充分混合后,于第0天和第7天皮下注射建立小鼠EAM模型;组织切片H ...
