混样核酸检测联合酶免法筛查献血者乙肝病毒感染的残余风险分析

open access: yesZhongguo shiyan zhenduanxue, 2021
目的了解无偿献血者血液筛查中血液标本的输血传播乙型肝炎病毒(HBV)残余风险,评估应用混样核酸检验联合酶免法在降低输血传播乙肝病毒残余风险的作用。方法选取2016年1月-2019年12月焦作市中心血站无偿献血者182 525人,所有献血者献血前均已同意献血且献血者末梢血体检合格。分别用酶免法和混样核酸检验法(8人/份)筛查献血者HBV,并对混样核酸检验有反应的样本进行拆分单测,对核酸检测阳性献血者追踪检测。结果 2016年1月-2019年12月混样核酸检验联合酶免法共检测出1 493份不合格样本 ...

肝素结合蛋白,降钙素原,中性粒细胞载脂蛋白联合检测对重症急性胰腺炎患者继发感染的评估作用

open access: yesZhongguo shiyan zhenduanxue, 2020
目的探讨肝素结合蛋白(HBP)、降钙素原(PCT)和中性粒细胞载脂蛋白(HNL)联合检测对重症急性胰腺炎(SAP)继发感染的评估价值。方法筛选SAP患者82例分为炎症组45例和非炎症组37例,检测两组患者血清的HBP、PCT和HNL水平,并比较这3种指标单独检测与联合检测诊断SAP继发感染的特异性、敏感性、阳性预测值、阴性预测值和符合率。结果炎症组患者血清HBP、PCT和HNL水平均显著高于非炎症组 ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

open access: yesConservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

open access: yesConservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

open access: yesConservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Psychometric framework for coexistence with large carnivores

open access: yesConservation Biology, EarlyView.
Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

HPV-DNA、TCT联合检测在宫颈癌中的诊断价值

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨分析联合检测HPV-DNA和TCT对宫颈癌的诊断价值。方法选择来我院进行妇科检查的女性486例,进行HPV-DNA、TCT检测。结果单项检测HPV-DNA敏感性最高(84.87%),但特异性(52.69%)以及阳性预测值(44.95%)最低;HPV-DNA+TCT联合检测的特异性(81.63%)、阳性预测值(64.61%)和诊断符合率(81.28%)都明显高于两者的单独检测,差异有统计学意义 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
