The metabolism of endogenous lipids in hepatocellular carcinoma [PDF]
研究背景:原发性肝细胞癌(以下简称原发性肝癌)是肝脏主要的恶性肿瘤,由于其起病隐匿,进展迅速,确诊时大多数患者已达到晚期或发生远处转移,治疗困难,因此提高原发性肝癌的诊断及愈后至关重要。有研究证明内源性大麻素系统可以通过多条通路产生抗肿瘤作用,但其与原发性肝癌发生发展的关系及治疗作用尚未完全阐明。 目的:本课题通过相关实验技术研究内源性大麻素系统与原发性肝癌之间的内在联系,探讨相关机制,以期发现原发性肝癌发生早期的生物标志物;并通过调控内源性脂质,探讨有效治疗原发性肝癌的特异性靶标。 方法 ...

The collective application of shorebird tracking data to conservation
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

How much biotic nativeness matters across human demographic groups
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Informing spatial conservation prioritization with species’ traits
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.
