The new electrochemical DNA sensor for detection of Mycobacterium tuberculosis and its drug resistance gene [PDF]
, 2016 耐药结核分枝杆菌，尤其是耐多药结核分枝杆菌的出现给结核病的检测和治疗带来了巨大的挑战，对人类健康产生了极大威胁。目前临床上常用的结核病的检测方法分别存在操作繁琐、仪器昂贵、耗时较长及易污染等不足。电化学DNA传感器是近几年发展起来的一种新型生物传感器，因其简单、灵敏、特异性强、易微型化等特点受到研究者的青睐，已被应用于多个领域的研究。然而电化学DNA传感器易受其他因素的干扰造成结果不稳定。实验前期构建的BSA单分子层控制组装界面为基础的电化学DNA传感器，有效地提高了体系的稳定性。本文在前期研究基础上 ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Compliance in Regulatory Gray Areas: The Case of the Organic Seed Standard
Policy Studies Journal, EarlyView.ABSTRACT Adaptive regulations, designed to balance flexibility with accountability, can embed provisions that unintentionally leave room for firms to shirk on their responsibilities by exploiting flexibility. We call these provisions “regulatory gray areas,” and ask: how should we understand (non‐)compliance in adaptive regulatory settings?
