Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

电力设备中,不同类型的放电因放电功率、能量的差异对设备绝缘的损害能力存在差异,即对绝缘的危害程度不同,确定局部放电类型是放电危险度评估的基础。文中对典型缺陷条件下的局部放电谱图提取了基本参量及统计参量等多种特征指纹;为了降低识别参量的维度,定义了特征向量可分性评估准则,并使用浮动前向搜索算法选取了可分性最优的9组特征参量;分别使用主成分分析、线性可分性分析、核主成分分析及通用可分性分析4种方法将特征向量降为2维,结果表明,使用通用可分性分析降维后特征参量可分性最优。之后,提出了多算法联合的模式识别分类器,

为了进一步了解PD-L1和CD8在卵巢癌中的表达情况以及评价其对预后的预测价值,我们建立了近10年来在我院完成初次肿瘤细胞减灭术治疗的卵巢高级别浆液性癌患者的临床病例资料库,进行回顾性分析及随访调查,研究影响卵巢高级别浆液性癌患者预后的相关临床及病理因素。同时制作卵巢高级别浆液性癌患者的病理组织芯片,通过免疫组织化学染色评价相关蛋白在卵巢癌病灶中的定位及表达水平情况,研究PD-L1和CD8在卵巢高级别浆液性癌中是否存在表达差异,同时分析蛋白表达强度与预后是否存在相关性,从而进一步验证PD ...

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.

间皮素、D2-40和Glypican3在卵巢肿瘤中的鉴别诊断意义
卵巢癌是第三大妇科恶性肿瘤,卵巢透明细胞癌临床较少见,约占卵巢上皮性恶性肿瘤的5%-10%,但在妇科病理鉴别诊断中却占有相当比例。与卵巢透明细胞癌相关的鉴别诊断包括原始生殖细胞肿瘤(特别是卵黄囊瘤和无性细胞瘤)及卵巢浆液性囊腺癌,卵巢癌的分类不同与预后及临床处理大不相同,需要更加客观的指标用来鉴别卵巢癌。本文的目的旨在mesothelin、D2-40、Glypican3在卵巢癌诊断和鉴别诊断中的作用加以探讨。

Hobbyist preferences for pet freshwater turtles
Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.

为探讨血清和尿中假尿苷(ψ)对恶性肿瘤的诊断价值,用高效液相色谱法测定了50例正常人、68例鼻咽癌、42例原发性肝癌、41例肺癌、24例急性白血病和相应部位良性疾病患者血清和尿中ψ的含量。正常人的血清和尿中ψ水平分别为3.08±0.49nmol/ml、21.6±2.9nmol/μmol肌酐。鼻咽癌、原发性肝癌、肺癌、急性白血病患者血清ψ分别为4.32±1.40、6.74±3.44、5.10±1.92、6.00±2.01nmol/ml,尿ψ分别为28.6±6.2、36.9±11.7、31.9±8.3、35.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.
