    为了帮助评估是否有潜在的抗微生物材料,表面,或涂层提供抗菌功效,国际上已经开发了许多标准化的测试方法。理想情况下,这些方法应生成支持材料功效的数据,当部署在预期的最终用途应用程序中时。这些方法可以根据其方法学方法进行分类,如悬浮试验,琼脂平板/区域扩散试验,表面接种试验,表面生长试验或表面粘附试验。为了支持那些对抗菌涂层功效感兴趣的人,这篇综述汇集了详尽的方法列表(用于多孔和非多孔材料),探索用于量化抗菌的方法学和环境参数,抗真菌药,或抗病毒活性。该分析表明,通常缺乏测试真菌或病毒的抗菌功效方法,而测试细菌的方法,真菌和病毒不是为了模拟最终用途/缺乏现实条件而设计的。因此,在医疗触摸屏中抗菌活性的许多应用,医用纺织品和手套以及运输座椅纺织品作为示例应用进行了探索,提供有关修改现有方法的指导,这些方法可以更好地模拟抗微生物材料的预期最终用途。
    To help assess whether a potentially antimicrobial material, surface, or coating provides antimicrobial efficacy, a number of standardised test methods have been developed internationally. Ideally, these methods should generate data that supports the materials efficacy when deployed in the intended end-use application. These methods can be categorised based on their methodological approach such as suspension tests, agar plate/zone diffusion tests, surface inoculation tests, surface growth tests or surface adhesion tests. To support those interested in antimicrobial coating efficacy, this review brings together an exhaustive list of methods (for porous and non-porous materials), exploring the methodological and environmental parameters used to quantify antibacterial, antifungal, or antiviral activity. This analysis demonstrates that antimicrobial efficacy methods that test either fungi or viruses are generally lacking, whilst methods that test bacteria, fungi and viruses are not designed to simulate end-use/lack realistic conditions. As such, a number of applications for antimicrobial activity across medical touch screens, medical textiles and gloves and transport seat textiles are explored as example applications, providing guidance on modifications to existing methods that may better simulate the intended end-use of antimicrobial materials.

    由于全球变暖和人类活动的增加,ThujakoraiensisNakai的野生种群(T.koraiensis)已经下降,把它置于危险之中。了解红杉对气候变化的响应以及确定优先保护区对于适当保护至关重要。利用69个红曲霉分布点和7个环境因子,Maxent模型用于预测T.koraiensis的潜在合适区域和空间变异模式,并使用Marxan保护规划模型来评估保护缺口区域。研究表明,影响红杉潜在适宜区域分布的主要环境因素包括海拔,最干旱月份的降水,等温线和最潮湿的四分之一的降水。在目前的气候条件下,红豆杉的适宜区域主要分布在三吉永县和白山市的长白山,Hamgyong-Bukto省西部的Hamgyong山脉,和江原道内的T\'aeback-Sanmaek山脉,熊岗山特别行政区和江原道。在未来的气候条件下,红杉适宜面积呈下降趋势,合适的区域将缩小到更高的海拔,咸镜山可能会成为避难所。基于GAP分析,69.69%的优先保护区位于自然保护区之外,这些保护空白区主要位于长白山南部和江原道。
    Due to global warming and increased human activity, the wild population of Thuja koraiensis Nakai (T. koraiensis) has dropped, placing it in danger. An understanding of the response of T. koraiensis to climate change and the determination of priority conservation areas are tremendously critical for proper conservation. Using sixty-nine T. koraiensis distribution points and seven environmental factors, the Maxent model was used to predict potentially suitable areas and spatial variation patterns of T. koraiensis and the Marxan conservation planning model was used to evaluate conservation gap areas. Research shows that the dominant environmental factors affecting the distribution of potentially suitable areas for T. koraiensis included elevation, precipitation of the driest month, isothermality and precipitation of the wettest quarter. Under the current climatic conditions, highly suitable areas for T. koraiensis are mainly distributed in the Changbai Mountains within Samjiyon County and Baishan City, the Hamgyong Mountains within the western part of Hamgyong-Bukto Province, and the T\'aeback-Sanmaek Mountains within Gangwon-do, Kumgangsan Special Administrative Region and Kangwon-do. Under future climate conditions, suitable areas for T. koraiensis show a decreasing trend, and the suitable area will be reduced to higher elevations, and the Hamgyong Mountains may become a refuge. Based on GAP analysis, 69.69% of the priority conservation areas of T. koraiensis are located outside of the nature reserve, and these conservation gap areas are primarily in the southern part of the Changbai Mountains and Kangwon-do.

    背景:我们对报告成人RSV发病率的观察性研究进行了全球综合文献综述,并确定了目前的证据差距。
    方法:搜索PubMed和Embase报告RSV发病率/累积发病率的英文出版物(2000-2022)和国会摘要(2019-2021)。横断面研究,案例系列,和其他仅估计RSV频率的设计被排除。搜索包括所有地理区域;数据是按年龄组和潜在条件提取的。
    结果:确定了528条潜在相关记录,其中37项主要研究与本综述相关.大多数证据来自高收入地区。大约三分之二的研究报告了RSV在医院环境中的发病率。15项研究包括或专门针对具有潜在疾病的成人人群的RSV发病率。研究在发病率的测量和呈现方面各不相同。RSV发病率估计值在地理区域内和地理区域之间差异很大。总的来说,RSV发病率随着年龄的增长而增加,在有潜在疾病的成年人中发病率最高。
    结论:RSV发病率的估计值在人群和地域之间差异很大。需要进一步的基于人群的研究,明确一致的病例定义和监测策略,以准确和可比地估计RSV发病率。特别是在差距分析确定的地理区域。
    BACKGROUND: We conducted a global comprehensive literature review of observational studies reporting RSV incidence in adults and determined current evidence gaps.
    METHODS: PubMed and Embase were searched for English-language publications (2000-2022) and congress abstracts (2019-2021) reporting RSV incidence rates/cumulative incidence. Cross-sectional studies, case series, and other designs estimating only RSV frequency were excluded. The search included all geographic areas; data were extracted by age group and underlying condition where available.
    RESULTS: 528 potentially relevant records were identified, of which 37 primary studies were relevant to this review. Most evidence was from high-income regions. Approximately two-thirds of the studies reported RSV incidence in the hospital setting. Fifteen studies included or focused exclusively on RSV incidence in adult populations with underlying conditions. Studies varied in their measurement and presentation of incidence. RSV incidence estimates were highly variable within and between geographic regions. Overall, RSV incidence tended to increase with age and was highest in adults with underlying conditions.
    CONCLUSIONS: Estimates of RSV incidence are highly variable across populations and geographies. Further population-based studies with well-defined consistent case definitions and surveillance strategies are needed for accurate and comparable estimates of RSV incidence, particularly in the geographic regions identified by the gap analysis.

    到目前为止,保护行动追踪器包含4126个树种的保护行动信息,包括2161种濒危物种,其中659人被归类为弱势群体,783濒临灭绝,719是极度濒危的。它涵盖了每个国家至少一种树种的保护行动信息;然而,89%的弱势群体需要更多信息,87%的濒危和77%的濒危树种。
    监测物种保护行动可以通过分享知识来支持保护实践的优先次序和扩大规模,加强合作,能够识别保护差距,并提供信息供决策者使用。跟踪物种一级的保护行动是,因此,对指导未来的保护工作至关重要。增加保护行动追踪器中的数据量将提高该工具指导未来保护工作的能力,避免树种灭绝。
    UNASSIGNED: The GlobalTree Portal, hosted by Botanic Gardens Conservation International, provides access to information on the approximately 58,000 tree species worldwide. Included in the GlobalTree Portal is the Conservation Action Tracker, a dynamic and collaborative database to identify and monitor conservation actions for tree species globally.
    UNASSIGNED: The Conservation Action Tracker collates conservation action information at the species level, including species recovery/action plans, ex situ collections, propagation protocols, in situ management, species protection policy, and education/awareness campaigns.
    UNASSIGNED: To date, the Conservation Action Tracker contains conservation action information for 4126 tree species, including 2161 threatened species, of which 659 are classified as Vulnerable, 783 as Endangered, and 719 as Critically Endangered. It covers conservation action information for at least one tree species in every country; however, more information is needed for 89% of Vulnerable, 87% of Endangered, and 77% of Critically Endangered tree species.
    UNASSIGNED: Monitoring species conservation actions can support the prioritization and scaling up of conservation practices by sharing knowledge, increasing collaboration, enabling the identification of conservation gaps, and making the information available to be used by decision-makers. Tracking conservation actions at the species level is, therefore, essential to guide future conservation efforts. Increasing the amount of data in the Conservation Action Tracker will improve the tool\'s ability to guide future conservation efforts and avoid the extinction of tree species.

    这项研究调查了黄喉men(Martesflavigula)和豹猫(Prionailurusbengalensis)的核心栖息地,韩国对栖息地破碎化敏感的两种濒危森林物种。覆盖InVEST-HQ和MaxEnt模型,通过分析当前保护区的差距,确定了优先保护区。InVEST-HQ模型显示,在0至1的尺度上,生境质量范围为0至0.86,而在环境保护价值评估图上,最适合的区域大部分为,指定为1级,是正确得出的。MaxEnt模型分析准确地捕获了黄喉貂和豹猫的生态特征,并确定了可能的发生区域。通过叠加两个结果,我们分析了最合适的黄喉貂和豹猫栖息地。差距分析确定了现有保护区的差距,并确定了优先保护区。核心区(14.7%)主要分布在庆北等地区的白杜干山保护区等森林中,庆南,和江原;12.9%在保护区之外,只有1.8%受到保护。将保护区和非保护区之间的重叠结果与不同的土地利用类型进行了比较。保护优先区域被确定为森林覆盖率超过95%的区域,为这两个物种提供适当的栖息地。这些发现可用于通过客观的生境分析确定优先保护区,并作为保护区指定和评估濒危物种生境保护的基础,从而促进生物多样性和生态系统保护。
    This study investigated core habitat areas for yellow-throated martens (Martes flavigula) and leopard cats (Prionailurus bengalensis), two endangered forest species sensitive to habitat fragmentation in Korea. Overlaying the InVEST-HQ and MaxEnt models, priority conservation areas were identified by analyzing gaps in currently protected areas. The InVEST-HQ model showed that habitat quality ranged from 0 to 0.86 on a scale from 0 to 1, and the majority of the most suitable areas on the Environmental Conservation Value Assessment Map, designated as grade 1, were derived correctly. The MaxEnt model analysis accurately captured the ecological characteristics of the yellow-throated marten and the leopard cat and identified probable regions of occurrence. We analyzed the most suitable yellow-throated marten and leopard cat habitats by superimposing the two results. Gap analysis determined gaps in existing protected areas and identified priority conservation areas. The core area (14.7%) was mainly distributed in forests such as the Baekdudaegan Mountains Reserve in regions such as Gyeongbuk, Gyeongnam, and Gangwon; 12.9% was outside protected areas, and only 1.8% was protected. The overlap results between protected and non-protected areas were compared with different land use types. Conservation priority areas were identified as those with more than 95% forest cover, offering an appropriate habitat for the two species. These findings can be used to identify priority conservation areas through objective habitat analysis and as a basis for protected area designation and assessment of endangered species habitat conservation, thereby contributing to biodiversity and ecosystem conservation.

    为了准确描述人类健康危害,人类,动物,必须整合机械数据,并且必须考虑所有三条证据与研究问题的相关性。机械数据通常对于动物和人类数据的完全整合以及表征相关性和不确定性至关重要。这种新颖的证据集成框架(EIF)提供了一种综合数据的方法,系统,流行病学和毒理学文献的基于质量的评估,包括体内和体外机理研究。它根据观察到的人类健康影响和化学物质的作用机理组织数据,提供一种支持证据综合的方法。基于疾病的组成部分使用最佳质量流行病学文献中研究的人类健康结果的证据,根据作者陈述的目的组织毒理学数据,与疾病的病理生理学确定毒理学数据的潜在相关性。基于机制的组件根据所提出的效果机制和数据支持事件来组织数据,从而导致每个端点,流行病学数据可能提供确凿的信息。EIF包括一种交叉分类和描述数据一致性的方法,并描述其不确定性。有时,两种组织数据的方法可能会导致不同的结论。这有助于识别知识差距,并显示不确定性对因果推理强度的影响。
    To accurately characterize human health hazards, human, animal, and mechanistic data must be integrated and the relevance to the research question of all three lines of evidence must be considered. Mechanistic data are often critical to the full integration of animal and human data and to characterizing relevance and uncertainty. This novel evidence integration framework (EIF) provides a method for synthesizing data from comprehensive, systematic, quality-based assessments of the epidemiological and toxicological literature, including in vivo and in vitro mechanistic studies. It organizes data according to both the observed human health effects and the mechanism of action of the chemical, providing a method to support evidence synthesis. The disease-based component uses the evidence of human health outcomes studied in the best quality epidemiological literature to organize the toxicological data according to authors\' stated purpose, with the pathophysiology of the disease determining the potential relevance of the toxicological data. The mechanism-based component organizes the data based on the proposed mechanisms of effect and data supporting events leading to each endpoint, with the epidemiological data potentially providing corroborating information. The EIF includes a method to cross-classify and describe the concordance of the data, and to characterize its uncertainty. At times, the two methods of organizing the data may lead to different conclusions. This facilitates identification of knowledge gaps and shows the impact of uncertainties on the strength of causal inference.

    预测全球环境变化对物种分布的影响是保护的首要任务,特别是对于大型食肉动物,有助于调节和维护生态系统。作为最广泛和适应性最强的大型猫科动物,遍布非洲和亚洲,豹子作为梯形和伞形物种对许多生态系统至关重要,然而,他们在他们的范围内受到威胁。我们使用种内物种分布模型(SDM)来预测未来气候和土地利用变化下豹子的范围适应性变化,并确定保护差距和机会。我们为三个西部豹子亚种生成了种内SDM,非洲,帕迪斯帕迪斯;阿拉伯人,Pantherapardusnimr;和波斯人,Pantherapardustulliana,豹子,以及与保护区(PA)覆盖范围重叠的预测。我们表明豹子亚种在环境关联和对未来变化的脆弱性方面有所不同。非洲和阿拉伯豹子预计将损失目前合适范围的约25%和约14%,分别,而波斯豹预计将经历约12%的射程增益。我们发现大多数预测合适的地区都没有受到保护,只有4%-16%的亚种范围属于PA,这些比例将来会减少。我们发现豹子亚种之间的高度可变响应凸显了在模拟气候和土地利用变化的脆弱性时考虑种内变异的重要性。预计落入PAs内的合适范围比例下降,威胁到全球有效保护豹子的能力,因为由于迫害,PAs外的存活率大大降低。因此,重要的是与当地社区合作,以解决负面的人与野生动物相互作用,并恢复栖息地,以保持PA覆盖率低的景观连通性。另一方面,预计南欧范围适用性的增加为其当代范围之外的扩张提供了机会,利用欧洲野化计划。
    Predicting the effects of global environmental changes on species distribution is a top conservation priority, particularly for large carnivores, that contribute to regulating and maintaining ecosystems. As the most widespread and adaptable large felid, ranging across Africa and Asia, leopards are crucial to many ecosystems as both keystone and umbrella species, yet they are threatened across their ranges. We used intraspecific species distribution models (SDMs) to predict changes in range suitability for leopards under future climate and land-use change and identify conservation gaps and opportunities. We generated intraspecific SDMs for the three western leopard subspecies, the African, Panthera pardus pardus; Arabian, Panthera pardus nimr; and Persian, Panthera pardus tulliana, leopards, and overlapped predictions with protected areas (PAs) coverage. We show that leopard subspecies differ in their environmental associations and vulnerability to future changes. The African and Arabian leopards are predicted to lose ~25% and ~14% of their currently suitable range, respectively, while the Persian leopard is predicted to experience ~12% range gains. We found that most areas predicted to be suitable were not protected, with only 4%-16% of the subspecies\' ranges falling inside PAs, and that these proportions will decrease in the future. The highly variable responses we found between leopard subspecies highlight the importance of considering intraspecific variation when modelling vulnerability to climate and land-use changes. The predicted decrease in proportion of suitable ranges falling inside PAs threatens global capacity to effectively conserve leopards because survival rates are substantially lower outside PAs due to persecution. Hence, it is important to work with local communities to address negative human-wildlife interactions and to restore habitats to retain landscape connectivity where PA coverage is low. On the other hand, the predicted increase in range suitability across southern Europe presents opportunities for expansion outside of their contemporary range, capitalising on European rewilding schemes.

    湿地是高度依赖湿地的水鸟最重要的栖息地之一,但由于人为活动的加剧,它们的栖息地不断丧失和退化。人类和自然资源的稀缺使有效的栖息地保护成为一个重要问题。这里,我们旨在研究安徽省水鸟栖息地保护方法,中国,东亚-澳大利亚高速公路上的重要中途停留和越冬区,具有丰富的湿地资源,会遭受严重的栖息地丧失和退化。我们评估了306个越冬水鸟栖息地的状况和重要性,并使用熵权法和广义加法模型确定了关键的环境影响和当前的保护差距。我们在安徽省发现了73个重要的水鸟栖息地,根据自然不连续方法将其分为重要级别(从I到V递减)。一级和二级生境主要位于长江洪泛区和淮河洪泛区的四级生境。差距分析显示,42个重要的水鸟栖息地存在保护差距,占总面积的57.53%。水鸟栖息地的重要性与海拔显着相关,归一化植被指数,湖区,和湖泊周长,但与道路距离或人口密度无关。本研究结果为水鸟栖息地保护规划提供了科学依据,这对于维持湿地生态系统功能至关重要。
    Wetlands are among the most important habitats of highly wetland-dependent waterbirds but are subject to ongoing habitat loss and degradation owing to intensified anthropogenic activities. The scarcity of human and natural resources makes effective habitat protection an important concern. Here, we aimed to investigate waterbird habitat protection methods for Anhui Province, China, a critical stopover and wintering area on the East Asian-Australasian Flyway that features rich wetland resources subject to significant habitat loss and degradation. We evaluated the status and importance of 306 wintering waterbird habitats and identified the key environmental influences and current protection gaps using the entropy weights method and generalized additive modeling. We found 73 important habitats for waterbirds in Anhui Province, which were classified into levels of importance (descending from I to V) according to the natural discontinuity method. Level I and Level II habitats were mainly located in the Yangtze River floodplain and Level IV habitats in the Huaihe River floodplain. The gap analysis showed that 42 important waterbird habitats had protection gaps, accounting for 57.53% of the total area. Waterbird habitat importance was significantly correlated with elevation, normalized vegetation index, lake area, and lake circumference but not with distance from roads or population density. The results of this study provide scientific information for waterbird habitat conservation planning, which is crucial for maintaining wetland ecosystem functions.

    对-苯二胺(PPD)在过去的五十年中已经用作氧化性毛发染料生产中的主要前体。许多健康危险与PPD的短期和长期使用有关,引起人们对其安全性的担忧。例如,越来越多的数据表明PPD与皮炎和过敏病例有关。
    通过在混合市售染发剂的成分后测量PPD浓度来量化染发剂中的PPD含量。
    总共测试了290种永久性染发剂。进行RP-HPLC-DAD分析以测定和定量PPD含量。
    PPD限值的估计平均值为0.89(95%CI[0.81-0.96])。在290个测试的染发剂中,混合后7.2%(n=21)超过推荐的PPD浓度。与其他地区的染料相比,印度和中国制造的染发剂在混合后的PPD含量明显超过2%(P=0.001)。此外,印度和阿联酋制造的染发剂更有可能对标签上的使用条件和警告有不完整的描述(P=0.002)。
    应重新评估与这些产品相关的现行法规的有效性。此外,通过使用良好的制造程序(GMPs),研究,以及不良反应的报告,染发剂应在其安全性和质量方面进行更好的控制和监测。
    UNASSIGNED: p-Phenylenediamine (PPD) has been used over the past five decades as a primary precursor in the production of oxidative hair dyes. Numerous health dangers are associated with the short- and long-term use of PPD, raising concerns about its safety. For instance, mounting data suggests that PPD is linked to dermatitis and allergy cases.
    UNASSIGNED: To quantify the PPD content in hair dyes by measuring the PPD concentration after mixing the ingredients of commercial hair dyes.
    UNASSIGNED: A total of 290 permanent hair dyes were tested. RP-HPLC-DAD analysis was performed to determine and quantify the PPD content.
    UNASSIGNED: The estimated mean of the PPD limit was 0.89 (95% CI [0.81-0.96]). Of the 290 tested hair dyes, 7.2% (n = 21) exceeded the recommended PPD concentration after mixing. Significantly more hair dyes manufactured in India and China had a PPD content exceeding 2% after mixing compared to dyes from other regions (P = 0.001). Moreover, hair dyes manufactured in India and the UAE were more likely to have incomplete descriptions of the conditions of use and warnings on the label (P = 0.002).
    UNASSIGNED: The effectiveness of the current regulations relevant to these products should be reevaluated. Moreover, through the use of good manufacturing procedures (GMPs), research, and the reporting of adverse reactions, hair dyes should be subjected to better control and monitoring in terms of their safety and quality.
