Use of consumer insights to inform behavior change interventions aimed at illegal pet turtle trade in China

open access: yesConservation 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

oleoylethanolamide improves spatial cognitive deficits through enhancing hippocampal neurogenesis after cerebral ischemia [PDF]

open access: yes, 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 ...

Cytological evaluation, culture and genomics to evaluate the microbiome in healthy rabbit external ear canals

open access: yesVeterinary 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

利用日采食量和营养需要量确定白犀牛的日粮标准

open access: yes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。

Study on Remote Monitoring System for Fish Activity and Water Quality Environment in Offshore Fish Cage [PDF]

open access: yes, 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 ...

Comparison of selected cytomorphological features of canine pemphigus foliaceus and superficial pyoderma

open access: yesVeterinary 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]

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 ...

A prospective study evaluating the correlation between local weather conditions, pollen counts and pruritus of dogs with atopic dermatitis

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 500-507, October 2024.
Abstract Background Canine atopic dermatitis (cAD) is a hereditary, generally pruritic and predominantly T‐cell‐driven inflammatory skin disease, involving an interplay between skin barrier abnormalities, allergen sensitisation and microbial dysbiosis.

An experimental study about the restrictive fluid resuscitation for burns shock [PDF]

open access: yes, 2015
研究目的 本研究通过颈内静脉置管大鼠烫伤休克模型,探讨限制性液体复苏在烧伤休克救治中的应用的可行性,为临床采用限制性液体复苏方案提供实验理论依据。 研究方法 将60只Wistar雄性大鼠按随机数字表法分成对照组、单纯颈内静脉置管组(单纯组)、实验1组、实验2组、实验3组、实验4组,每组10只。单纯颈内静脉置管组和实验1、2、3、4组均进行颈内静脉置管术,对照组颈部不做处理;所有大鼠均进行背部及双侧脱毛,术后大鼠单笼饲养1天;次日,实验1、2、3、4组大鼠麻醉后背部、双侧浸于100˚ ...
