Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Harnessing social media data to track species range shifts

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

CHINA’S LAND FINANCE AS ACTIVE MODE OF LAND DEVELOPMENT AND INFRASTRUCTURE DELIVERY: Reality, History and Prospects

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.
Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World

open access: yesWorld Affairs, Volume 188, Issue 4, Winter 2025.
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Z-十八碳-9-烯-丙磺酰胺对糖尿病认知功能障碍小鼠学习记忆功能的影响 [PDF]

open access: yes, 2018
探索新化合物Z-十八碳-9-烯-丙磺酰胺(N15)对糖尿病认知功能障碍(DACD)小鼠学习记忆功能的作用及机制。采用链脲佐菌素(STZ)连续小剂量腹腔注射以及高脂高糖加STZ诱导2型糖尿病小鼠模型,N15(50和100mg·kg-1·d-1)连续灌胃给药6周,于给药末期进行跳台、避暗以及Morris水迷宫测试以评价小鼠学习记忆功能;对海马内葡萄糖和乳酸水平进行测定;通过realtimePCR测定海马内突触成长相关蛋白-43(GAP-43)、突触素(SYN)、脑源性生长因子(BDNF)和神经营养因子-3 ...

Multi-modal fMRI study on brain structure and function in different factors induced rat chronic obstructive pulmonary disease [PDF]

open access: yes, 2015
慢性阻塞性肺病(chronicobstructivepulmonarydisease,COPD)脑结构和功能的异常在近些年受到了越来越多的研究关注。先前的神经影像学研究已经发现COPD伴随着白质完整性的损害和灰质的丢失,以及功能连接网络的异常。但是吸烟和非吸烟(如慢性肺部炎症)诱导的COPD病人脑部形态学和功能的异同,以及吸烟和感染因素的综合诱导是否加重了脑损害尚不清楚。致病因素和COPD病人脑部异常的特征性对应关系仍待进一步的探究 ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

海洛因及补偿AMP和GMP对大鼠海马组织腺苷脱氨酶的影响

open access: yesZhongguo shiyan zhenduanxue, 2010
目的探讨海洛因及补偿AMP和GMP对海马组织嘌呤核苷酸分解代谢关键酶ADA的影响。方法剂量递增腹腔注射海洛因及嘌呤核苷酸,建立了海洛因及补偿AMP和GMP的给药与依赖大鼠模型,用试剂盒检测海马组织腺苷脱氨酶(ADA)的活性。提取海马组织总RNA,采用逆转录聚合酶链反应检测海马组织ADA mRNA的水平,以β-actin mRNA为内标。结果海马组织中ADA含量测定结果显示,与盐水对照组相比,核苷酸组和海洛因组的海马组织ADA含量明显升高 ...

The role of MiR-23b-3p in the epileptogenesis [PDF]

open access: yes, 2016
癫痫是指脑部持续存在能导致癫痫反复发作,并出现相应的神经生物学、认知、心理学,以及社会学等方面的后果的脑部疾患。目前miRNA在癫痫发生发展中的作用引起越来越多的重视。miR-23b-3p是具有多种生物学作用的miRNA,如调节神经元增殖、分化和凋亡等,参与多种神经退行性疾病的病理机制。 本研究通过腹腔注射海人酸(Kainicacid,KA)构建小鼠癫痫模型,发作达到Racine标准的4-5级作为实验组纳入标准,对照组注射相同剂量的生理盐水,并应用荧光定量PCR法对皮层和海马组织中miR-23b-3p ...

Using online reports of seahorse seizures to track their illegal trade

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...
