Evaluation of filaggrin 2 expression in dogs with atopic dermatitis before and after oclacitinib maleate administration

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 453-461, August 2025.
Background – Canine atopic dermatitis (cAD) is a chronic, inflammatory, multifactorial and pruritic disease. The presence of skin barrier impairment (e.g. filaggrin alterations), along with abnormal immune responses, can negatively impact cutaneous barrier function.

Establishment of An Effective System to Develop Avian Polyclonal Antibodies and Its Primary Application [PDF]

open access: yes, 2016
小鼠单克隆抗体技术已成为生物医药领域不可或缺的研究工具,在疾病的诊断和治疗领域也得到广泛应用。然而,由于小鼠自身免疫系统的局限,某些抗原或表位,特别是同为哺乳动物的人体抗原在小鼠体内可能因为种属相近而不易产生好的免疫应答,给制备相应的小鼠单克隆抗体造成一定的困难。因此,有必要基于其它种属动物开发新的抗体制备技术。禽源抗体技术也称卵黄抗体技术(简称IgY技术),是用免疫原刺激禽类动物,产生相应的特异性抗体,该抗体会转运、储存在卵黄中,经特殊的提取技术,可从卵黄中获得大量特异性的多克隆抗体的一种抗体制备技术。

Drought decreases carbon flux but not transport speed of newly fixed carbon from leaves to sinks in a giant bamboo forest

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1746-1759, July 2025.
In forests dominated by large clonal plants, such as giant moso bamboo, drought can alter the allocation of newly assimilated C within the tissues of source ramet but may not affect its allocation among interconnected ramets or within plant–soil systems.

Clone、construction and expression of Synechocystis sp.PCC 6803 Acetyl- CoA carboxylase gene for fat production [PDF]

open access: yes, 2016
在化石燃料日益枯竭、环境污染逐渐威胁人类生存的今天,生物柴油在提供可再生能源的同时还可以减少温室气体,从而受到世界各国的广泛重视。蓝藻为光合自养微生物,是大气碳循环主要贡献者,其生物柴油产量是油料作物的8~24倍。乙酰辅酶A羧化酶(acetyl-coenzymeAcarboxylase,ACCase)是生物体内脂肪生物合成的关键酶,研究发现,过量表达ACCase能够促进生物体脂肪的合成。相对于蓝藻,大肠杆菌具有遗传背景清楚、生长速度快等特点 ...

General‐purpose genotypes and evolution of higher plasticity in clonality underlie knotweed invasion

open access: yesNew Phytologist, Volume 246, Issue 2, Page 758-768, April 2025.
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.

Preparation and Application of Monoclonal Antibody against Puerarin [PDF]

open access: yes, 2012
葛根为豆科植物野葛或粉葛的干燥根,为常用中药之一,具有解肌退热、生津、透疹、升阳止泻的功效,多用于治疗外感发热、头痛、项强、消渴、麻疹不透、热痢、泄泻、高血压等症状。葛根素(Puerarin,PU)是葛根的主要活性成分,属于黄酮类化合物,药理作用广泛,是一种很有开发前景的药物。 本实验采用杂交瘤技术制备葛根素的单克隆抗体,在此基础上建立葛根素的酶联免疫吸附分析法检测技术,对葛根中药及中成药中葛根素的含量进行检测和评价。 主要的实验结果如下: (1)采用高碘酸钠法合成免疫人工抗原PU ...

银鲫果糖-1,6-二磷酸酶的分子克隆与表达分析 [PDF]

open access: yes, 2010
果糖-1,6-二磷酸酶(EC 3.1.3.11)是糖异生中的关键限速酶之一,在糖代谢中起重要作用。哺乳动物存在肝脏型和肌肉型两种果糖-1,6-二磷酸酶同工酶,分别由Fbp1和Fbp2编码。银鲫作为我国重要的经济养殖鱼类,尚无果糖-1,6-二磷酸酶基因的有关资料,其组织分布特征和胚胎发育模式亦不清楚。本研究采用RACE方法从银鲫原肠胚SMART cDNA文库中扩增了果糖-1,6-二磷酸酶基因的全长cDNA,其长度为1170 bp,编码337个氨基酸残基,多重序列比对和系统发育分析表明该基因为肝脏型果糖 ...
