麝的群体饲养

open access: yes野生动物学报, 1982
人工养麝已经取得了笼养、舍养及小型圈养的成功经验,但在群体饲养方面,迄今尚未见报道。笼养和舍养纯属个体饲养,至于一雄多雌或多雄、多雌的小型圈养,因其饲养目的和管理措施均无集群要求,故基本上也是个体性质的饲养方式。从理论上讲,麝的先天独居性可能是群养的主要障碍 ...

Functions of DHP and its nuclear receptor on reproductive neuroendocrine in zebrafish (Danio rerio) [PDF]

open access: yes, 2016
本文研究了DHP对野生型和孕酮核受体敲除纯合型两种类型雄性斑马鱼垂体中促性腺激素β亚基基因(fshb和lhb)、脑中多巴胺合成限速酶酪氨酸羟基化酶基因(th2)及多巴胺二型受体基因(drd2a和drd2b)和促性腺激素释放激素基因(gnrh2和gnrh3)mRNA表达的影响。主要研究结果如下: 1.野生型雄性斑马鱼垂体中促性腺激素β亚基基因(fshb和lhb)mRNA表达呈现周日变化趋势,可分为基础表达期、上升表达期和高峰表达期3个期,高峰表达期的mRNA表达量显著高于其它2个期 ...

An open‐label pilot study on an adsorbent mousse containing adelmidrol in client‐owned cats with feline atopic skin syndrome and associated seborrhoea

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 638-646, October 2025.
Background – Besides pruritus and skin lesions, cats with feline atopic skin syndrome (FASS) may have seborrhoea. Hypothesis/Objectives – The aim of this pilot study was to investigate whether an adsorbent mousse containing tapioca starch, adelmidrol and a nonpharmacological antimicrobial complex could decrease FASS‐associated seborrhoea in cats ...

Validation of the Equine Urticaria Activity Score for the assessment of chronic recurrent urticaria in horses

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 630-637, October 2025.
Background – Recurrent urticaria is common in horses. The pathophysiology is poorly understood and treatment options are limited. Often only glucocorticoids are effective for controlling clinical signs, albeit with potential adverse effects. Studies investigating new treatments need a validated objective scoring system for the grading of skin lesions ...

人工饲养麝鼠有十大好处

open access: yes野生动物学报, 1988
麝鼠又名耗子,青根貂,是珍贵的小型细毛皮动物之一。近年来,我国将野生麝鼠逐渐驯化,开始人工饲养获得成功。人工饲养麝鼠成本低,收入高,是一项很有发展前途的家庭饲养业。1、增加收入:人工饲养麝鼠是一项投资少,见效快,收益高的家庭饲养业。饲养一对麝鼠,仅年产毛皮一项收益360元左右,如果饲养10对麝鼠就是3600元左右(现行麝鼠皮县城以上收购价格,每张13元左右。)

Study on Roles of Dlk2 in Skeletal Muscle Development [PDF]

open access: yes, 2015
Dlk2(Delta-like2homolog)属EGF样跨膜蛋白,与同家族成员Dlk1(Delta-like1homolog)高度同源。现有研究发现Dlk1在包括脂肪生成和肌肉生成在内的多个发育过程中发挥重要作用。但是目前对Dlk2的研究还主要限于脂肪生成过程,迄今为止尚未见Dlk2在骨骼肌生成方面的报道。 本研究首次考察了Dlk2在骨骼肌发育中的作用。首先,通过检测不同发育时期的鸡骨骼肌组织中cDLK2的表达水平,我们发现其在胚胎骨骼肌发育早期较高,而随发育的进行逐渐降低并在出壳后维持较低水平 ...

Amphibians and Reptiles of Ethiopia—Biogeography, Conservation Priority Areas, and Potentials for “One Plan Approach” Conservation Measures 埃塞俄比亚的两栖爬行动物——生物地理学、保育优先区及“一体化方案”保育措施的潜力

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 442-463, September 2025.
In this study, we analyze the conservation status of Ethiopia's amphibian and reptile diversity in terms of coverage with protected areas and global representation in conservation breeding facilities. We identify conservation gaps and suggest priorities for improvement.

Study of Pelo deficiency mediated antiviral activity [PDF]

open access: yes, 2012
果蝇是研究抗病毒天然免疫以及病毒与宿主相互作用的理想模型。我们以果蝇C病毒(DrosophilaCVirus,DCV)为病原体对已有的突变体果蝇库进行筛选,找到了一个对DCV感染更为抵抗的果蝇株并鉴定出其体内Pelo基因的表达量下降。通过基因敲除和表型回复实验,我们证实了Pelo基因的缺失的确可以使果蝇对DCV的感染更为抵抗。此外,DCV以及其他多种病毒的复制在Pelo基因敲除型果蝇中都变慢,说明Pelo基因缺陷可能介导了广谱的抗病毒免疫。 我们研究发现,Pelo并不参与目前已知的果蝇抗病毒免疫途径 ...
