野生动物学报, 2015 对赤大袋鼠进行行为训练有利于建立赤大袋鼠与饲养员的互信关系,减少赤大袋鼠在饲养管理工作中的应激反应。选取4只成年雌性赤大袋鼠进行了为期1个月的行为训练工作。训练目标为:赤大袋鼠能够跟随目标棒移动,并主动上秤进行体重称量。在行为训练过程中经历了脱敏、建立响片条件反射、引入目标棒、跟随目标棒移动、奖励延迟、行为保持等几个阶段。克服了赤大袋鼠白天活跃度低,可视能力弱的训练难点,大大减少了健康体检时赤大袋鼠体重的称量时间。

18F-FDGPET/CT显像检测SD大鼠肝纤维化 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 2019 【目的】探讨18F-FDGPET/CT显像评价SD大鼠肝纤维化疾病。【方法】12只（170±10）g雄性SD大鼠随机分为模型组（TAA组）和对照组，每组6只。模型组大鼠每周两次腹腔注射4%硫代乙酰胺，每次剂量200mg/kg；对照组腹腔注射等比例生理盐水。注射6周后对两组大鼠行18F-FDGPET/CT显像，检测肝组织摄取18F-FDG情况。显像后解剖两组大鼠观察肝脏解剖形态学变化并取其肝脏用于HE染色、Masson染色和羟脯氨酸含量测定。【结果】模型组解剖形态显示肝脏肿胀、表面欠光滑、边缘圆钝 ...

Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, EarlyView.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...
