Study on an Agglutinin Isolated from Serum of Grass Carp (Ctenopharyngodon idellus)(草鱼血清凝集素的研究)
Zhejiang Daxue xuebao. Lixue ban, 1999 从草鱼血清分离到一种天然的凝集素分子，能够凝集多种不同的抗原物质，其组成成分为糖蛋白，具有耐热和耐酸碱性，对β－巯基乙醇敏感.凝集反应受温度、反应介质的pH、离子强度以及时间等因素的影响.经糖的专一性抑制实验显示，半乳糖和乳糖对凝集反应的抑制作用最强，甘露糖和N－乙酰葡萄糖胺也有一定的抑制作用，说明这4种糖分子可能在凝集过程中起主要作用.

Disasters, Volume 47, Issue 2, Page 437-463, April 2023., 2023 Efforts to reduce the gap between the research evidence base and humanitarian responses have focused on producing quality evidence and ensuring its use in decision‐making. Yet, how evidence translates into field‐level implementation is not well understood in humanitarian contexts.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

World Medical &Health Policy, Volume 17, Issue 4, Page 745-766, December 2025.ABSTRACT This paper aimed to describe and analyze the factors that shaped the political priority of global neurosurgery from 2015 to 2022. The neurosurgery community formed a movement (that can be described as a global health network) to advocate for the neurosurgical patient to ensure safe, timely, and affordable neurosurgical care for all, and ...

Zhongguo shiyan zhenduanxue, 2008 目的观察不同肝病患者血清碱性磷酸酶凝集素结合率的变化。方法采用凝集素亲和沉降法对39例健康者、41例原发性肝癌患者及98例其它肝病、消化道肿瘤患者和孕妇等血清碱性磷酸酶L型红腰豆凝集素、小扁豆凝集素、蔓陀萝凝集素结合率进行测定。结果原发性肝癌患者血清碱性磷酸酶三种凝集素结合率均明显升高,尤以L型红腰豆凝集素结合率升高显著。结论血清碱性磷酸酶凝集素结合率测定可用于原发性肝癌的实验诊断和鉴别诊断。

Phaseolus lunatus Linn vel aff的种子中A型血专一性凝集素的研究
四川大学学报. 自然科学版, 1991 用亲和层析法从Phaseolus lunatus Linn vel aff的种子中纯化出一种对人类A型血专一的凝集素.该凝集素的粗浸提液都只对A型血细胞凝集,而对B、O型绝不凝集.当纯化的凝集素浓度为0.98μg/mL时,即能凝集A型血细胞,GalNAc、对硝基苯酚-β-D-吡喃半乳糖苷能抑制其凝集作用;酚—硫酸法测得凝集素含有3.8％的中性糖;该凝集素是一个促有丝分裂原,其细胞转化为67.9％;它的分子量为56500,有两种亚基,分子量分别为17200和14600.凝集素分子中亮氨酸和缬氨酸含量较高 ...
