Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Illegal poaching and overexploitation for the international pet trade are among the greatest threats to freshwater turtles in Southeast Asia. Expanding consumer research in China is crucial to filling knowledge gaps about the scale and structure of illegal trade and developing audience‐targeted and relevant interventions that may reduce demand

Study on Remote Monitoring System for Fish Activity and Water Quality Environment in Offshore Fish Cage [PDF]
, 2016 在全球海洋渔业资源日益衰减的今天，深水网箱以其抗风浪、耐海流能力强、养殖容量大、高产高效、环保等优势成为现代耕海牧渔的发展方向。深水网箱养殖过程中，由于网箱离岸远，范围广，水体浑浊，不容易观察鱼群活动状态，同时也往往难以把握合适的投饲量，投饵过少将影响鱼类生长健康，过多则增大养殖饲料成本，同时剩余饵料又会污染环境。为了进行鱼群状态监测和避免饲养投喂的随意性和盲目性，急需加强深水网箱鱼群状态与水质环境监测，为正确判断鱼群食欲、科学进行投饲提供重要参考依据。本文根据深水网箱养殖环境的特殊要求 ...

Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

野生动物学报, 2015 目前,在石林龙晖野生动物科研中心有限公司饲养场里有80头犀牛,在人工圈养时,每头犀牛的采食量也不尽相同,采食量的多少受很多方面的影响,比如年龄、性别、体重、活动量、饲草的适口性等。通过长时间的观察,大多数犀牛更喜欢采食黑麦草、苜蓿干草、玉米秸秆、野豌豆等饲草,所以在饲养场里我们以这几种饲草作为主要饲草来对白犀牛进行人工饲喂。本文通过白犀牛日采食量和营养需要量来确定其合理的饲喂方案,这种方法更有利于白犀牛的科学饲养,在保证其日采食量的基础上,满足其营养需要,使白犀牛达到健康标准。

oleoylethanolamide improves spatial cognitive deficits through enhancing hippocampal neurogenesis after cerebral ischemia [PDF]
, 2015 我们先前的研究表明油酰乙醇胺（OEA）对急性脑缺血损伤具有神经保护作用。本研究的目的是探讨OEA对脑缺血引起的空间认知障碍，海马长时程增强作用（LTP）的抑制作用和海马神经发生的影响。结果表明：OEA30mg/kg显著改善大鼠脑缺血后空间认知功能障碍，促进海马长时程增强。另外，我们证实OEA通过促进海马神经发生改善脑缺血后的认知障碍。进一步的研究表明，OEA明显增加海马组织脑源性神经营养因子（BDNF）和过氧化物酶体增殖活化受体（PPARα）的表达 ...

Veterinary Dermatology, Volume 35, Issue 5, Page 524-535, October 2024.Background – Cytological detection of acantholytic keratinocytes (acantholytic cells [AC]) helps to identify canine pemphigus foliaceus (cPF) yet AC also occurs in superficial pyoderma (SP), the main differential diagnosis. Hypothesis/Objectives – To compare selected cytomorphological features of cPF and SP and to establish cytological diagnostic ...

Study of Pelo deficiency mediated antiviral activity [PDF]
, 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 ...

Design and Implementation of Pork Safety Traceability System Based on Open-source Framework [PDF]
, 2015 社会发展和人们生活水平日益提高，国内个别食品安全事件的出现，政府和消费者都开始重视畜产品质量安全问题。猪肉的生产在畜产品中占有较高的比例，而我国作为最大的猪肉消费量国，近年来食品安全问题频发，因此，研究畜产品质量管理体系，进一步提高猪肉生产质量，具有重大的理论价值和必要的现实意义。然而，由于供给体系的复杂化以及缺乏生产信息的有效传递方式，猪肉安全生产、监督和管理面临着很多问题。可追溯系统被认为是猪肉食品质量安全管理的有效手段，已经受到消费者及食品质量监管部门的普遍关注 ...

Veterinary Dermatology, Volume 35, Issue 4, Page 408-417, August 2024.Background – Supplementation of polyunsaturated fatty acids (PUFA) enables dose reduction of prednisolone and ciclosporin in canine atopic dermatitis (cAD). Objective – To determine if oral administration of PUFA can reduce the dose of oclacitinib for cAD. Conclusion – Oral supplementation of PUFA allowed dose reduction of oclacitinib and improved pVAS,
