Rare Metals, EarlyView.ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites
Rare Metals, EarlyView.ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Shuitu Baochi Xuebao, 2007 在连续6年稻麦轮作系统中，研究不同秸秆施用方式下接种蚯蚓对土壤微生物生物量、活性（基础呼吸）及群落功能多样性（BIOLOG单一碳源利用指纹方法）的影响，试验设5个处理：对照（CK）、秸秆表施（M）、秸秆混施（I）、秸秆表施且接种蚯蚓（ME）、秸秆混施且接种蚯蚓（IE）。不同秸秆施用下接种蚯蚓均对土壤微生物生物量、微生物生物活性和群落碳源利用能力产生显著影响：两种秸秆施用方式下接种蚯蚓均增加微生物生物量；秸秆表施并接种蚯蚓导致微生物活性、碳源利用丰富度和多样性指数均降低，而在秸秆混施下则均升高 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Assessing the Effect of Deservingness Cues on Tolerance for Administrative Burdens
Policy Studies Journal, EarlyView.ABSTRACT Beneficiaries of public programs must overcome several administrative challenges. Given what we know about the politics of the welfare state, it seems likely that the public's willingness to support reductions in burdens may be associated with the characteristics of potential policy targets including their life circumstances and their race ...
