    随着越来越多的口腔癌诊断和指导建议患者向医生或牙医进行评估,在搜索有关口腔癌的信息时,患者可以先看看他们的牙科诊所网站。这项研究旨在评估牙科实践网站上提供的有关口腔癌的患者信息的差异。
    曼彻斯特地区有活跃网站的牙科实践包括评估是否提供了有关减少口腔癌风险因素的任何信息,需要注意的迹象,以及口腔癌筛查是否被包括在一般检查中,根据英国和爱尔兰口腔医学会(BISOM)和英国癌症研究中心(CRUK)关于口腔癌诊断和预防的联合声明,使用3分得分。
    总共,66.6%(n=60)的实践在其网站上没有提供有关口腔癌筛查和预防的可访问信息。只有12.2%(n=11)讨论了口服筛查的所有三个因素,症状和减少危险因素。作为常规检查的一部分,筛查最常被提及,占27%(n=24),23%(n=21)的实践和13%(n=12)的症状讨论了危险因素.
    牙科诊所网站上缺乏关于口腔癌的患者信息。为了克服互联网上缺乏质量保证的问题,牙医可以通过他们的牙科实践网站提供事实信息。这可以帮助提高患者的意识,从而帮助早期发现,改善患者预后。
    UNASSIGNED: With increasing numbers of oral cancer diagnoses and guidance recommending that patients approach their doctors or dentists for assessments, when searching for information regarding mouth cancer, patients may first look to their dental practice website. This study aimed to evaluate the variance of patient information provided regarding oral cancer on dental practice websites.
    UNASSIGNED: Dental practices within the Manchester area with an active website were included with assessment of whether there was any information provided regarding reducing oral cancer risk factors, signs to look out for and if oral cancer screening was included as part of the general check-up, using a three-point score based on the joint statement from the British and Irish Society for Oral Medicine (BISOM) and Cancer Research UK (CRUK) regarding oral cancer diagnosis and prevention.
    UNASSIGNED: In total, 66.6% (n=60) of practices provided no accessible information regarding oral cancer screening and prevention on their websites. Only 12.2% (n=11) discussed all three factors of oral screening, symptoms and reducing risk factors. Screening as part of routine examination was most frequently mentioned at 27% (n=24), risk factors were discussed by 23% (n=21) of practices and symptoms to be aware of by 13% (n=12).
    UNASSIGNED: There is a lack of information available to patients on dental practice websites regarding oral cancer. To overcome lack of quality assurance on the internet, dentists can provide factual information via their dental practice websites. This could help with improving patient awareness and therefore aiding in early detection, improving patient outcomes.

    翻译延伸因子1α(EF1α)蛋白是一种高度保守的G蛋白,对于所有真核生物中的蛋白质翻译至关重要。EF1α在42°C的温度下在体外处理2h迅速变得不溶,但即使在长时间暴露于高达45°C的温度后,通常仍可在体内溶解,这表明在热胁迫下存在保持EF1α在植物细胞中可溶的保护机制。当暴露于45°C时,EF1α在体内快速不溶解,导致约40%的蛋白质在9小时后聚集。鉴于其在蛋白质翻译中的既定作用,热诱导的聚集最有可能影响伸长因子的功能。EF1α的GTP结合形式和GDP结合形式的组成型突变体的过表达导致耐热性显着降低。这些发现为支持EF1α的关键作用提供了证据,一种热敏蛋白,植物的耐热性。
    The translation elongation factor 1α (EF1α) protein is a highly conserved G protein that is crucial for protein translation in all eukaryotic organisms. EF1α quickly became insoluble at temperatures 42 °C treatment for 2h in vitro, but generally remained soluble in vivo even after being exposed to temperatures as high as 45 °C for an extended period, which suggests that protective mechanisms exist for keeping EF1α soluble in plant cells under heat stress. EF1α had fast in vivo insolubilization when exposed to 45 °C, resulting in about 40% of the protein aggregating after 9 h. Given its established role in protein translation, heat-induced aggregation is most likely to impact the function of the elongation factor. Overexpression of constitutive mutants in both GTP-bound and GDP-bound forms of EF1α resulted in significantly decreased heat tolerance. These findings provide evidence to support the critical role of EF1α, a thermosensitive protein, in the heat tolerance of plants.

    目前尚不清楚国内生产总值(GDP)和绿色是否对空气污染与呼吸系统疾病之间的关联具有额外的调节作用。利用分布滞后线性模型的时间分层案例交叉设计,我们分析了2016年1月1日至2019年12月31日北京6种污染物(PM2.5,PM10,NO2,SO2,O3和CO)与555,498例呼吸住院患者之间的关联.我们采用条件逻辑回归,根据气象条件进行调整,假期和流感,计算住院风险的百分比变化。随后,我们使用双样本z检验进行了亚组分析以研究潜在的效应修饰.PM2.5,PM10,NO2,SO2和O3每增加10μg/m3,导致0.26%的增加(95CI:0.17%,0.35%),0.15%(95CI:0.09%,0.22%),0.61%(95CI:0.44%,0.77%),1.72%(95CI:1.24%,2.21%),和0.32%(95CI:0.20%,0.43%)在招生中,分别。此外,CO水平增加1mg/m3导致2.50%(95CI:1.96%,3.04%)录取率上升。与NO2的链接(p<0.001),SO2(p<0.001),O3(在温暖的季节,p<0.001),居住在绿色水平较高的地区的患者中,CO(p<0.001)明显较弱。没有观察到GDP的显着修饰作用。绿色可以帮助减轻空气污染物的影响,而GDP的作用需要进一步研究。
    It is unclear whether Gross Domestic Product (GDP) and greenness have additional modifying effects on the association between air pollution and respiratory system disease. Utilizing a time-stratified case-crossover design with a distributed lag linear model, we analyzed the association between six pollutants (PM2.5, PM10, NO2, SO2, O3, and CO) and 555,498 respiratory hospital admissions in Beijing from 1st January 2016 to 31st December 2019. We employed conditional logistic regression, adjusting for meteorological conditions, holidays and influenza, to calculate percent change of hospitalization risk. Subsequently, we performed subgroup analysis to investigate potential effect modifications using a two-sample z test. Every 10 μg/m3 increase in PM2.5, PM10, NO2, SO2, and O3 led to increases of 0.26% (95%CI: 0.17%, 0.35%), 0.15% (95%CI: 0.09%, 0.22%), 0.61% (95%CI: 0.44%, 0.77%), 1.72% (95%CI: 1.24%, 2.21%), and 0.32% (95%CI: 0.20%, 0.43%) in admissions, respectively. Also, a 1 mg/m3 increase in CO levels resulted in a 2.50% (95%CI: 1.96%, 3.04%) rise in admissions. The links with NO2 (p < 0.001), SO2 (p < 0.001), O3 (during the warm season, p < 0.001), and CO (p < 0.001) were significantly weaker among patients residing in areas with higher levels of greenness. No significant modifying role of GDP was observed. Greenness can help mitigate the effects of air pollutants, while the role of GDP needs further investigation.

    微塑料(MP)污染正在发展成为全球最紧迫的环境问题之一。这项研究评估了经济活动对中国北方17个特大城市大气MP污染的影响,分析大气MPs沉积通量与城市人口等变量之间的相关性,国内生产总值(GDP),和产业结构。结果表明,MP污染明显受到与GDP增长相关的人类活动的影响,人口,以及第三产业,其中MP污染与GDP增长关系最为密切。聚丙烯,聚酰胺,聚氨酯,和聚乙烯被确定为大气MPs的主要成分。大气降尘中MPs的平均粒径为78.3µm,并且MP颗粒的频率随着颗粒尺寸的减小而增加。研究结果强调了社会经济发展与大气MP积累之间的复杂关系,为制定有针对性的减排战略提供必要的见解。
    Microplastic (MP) pollution is evolving into one of the most pressing environmental concerns worldwide. This study assessed the impact of economic activities on atmospheric MP pollution across 17 megacities in northern China, analyzing the correlation between the deposition flux of atmospheric MPs and variables such as city population, gross domestic product (GDP), and industrial structure. The results have shown that the MP pollution is obviously impacted by human activities related to increased GDP, population, as well as tertiary service sector, in which the MP pollution shows most close relationship with the GDP growth. Polypropylene, polyamide, polyurethane, and polyethylene were identified as the primary components of atmospheric MPs. The average particle size of MPs in atmospheric dustfall is 78.3 µm, and the frequency of MP particles increases as the particle size decreases. The findings highlight the complex relationship between socio-economic development and atmospheric MP accumulation, providing essential insights for the formulation of targeted emission reduction strategies.

    经济损失估计对于决策者制定在大流行紧急情况下平衡经济和健康问题的政策至关重要。然而,这项任务既耗时又资源密集,在紧急情况下面临挑战。
    为了解决这个问题,我们建议使用用电量(EC)和夜间灯光(NTL)数据集来估计总量,商业,以及菲律宾COVID-19封锁造成的工业经济损失。采用回归模型建立GDP与EC和NTL的关系。然后,使用基本统计数据和天气数据开发了模型来估计反事实EC和NTL,从中得出反事实GDP。从2020年到2021年,实际GDP和反事实GDP之间的差异产生了经济损失。
    本文重点介绍了三个发现。首先,回归模型结果表明,基于EC(adj-R2≥0.978)的模型比使用NTL(adj-R2≥0.663)的模型更好地解释GDP;然而,结合EC和NTL改善了预测(adj-R2≥0.979)。第二,可以使用基于统计数据和天气数据的模型来估计反事实EC和NTL,这些数据解释了大流行前值的81%以上。最后,预计2020年总损失为2.9万亿PhP,2021年为3.2万亿PhP。超过三分之二的损失发生在商业部门,因为它对政策和COVID-19病例激增做出了反应。相比之下,工业部门主要受到封锁实施的影响。
    这种方法可以监测长期和大规模危害(如COVID-19大流行)造成的经济损失。这些发现可以作为经验证据,用于倡导在大流行情景中平衡公共卫生和经济的针对性策略。
    Economic loss estimation is critical for policymakers to craft policies that balance economic and health concerns during pandemic emergencies. However, this task is time-consuming and resource-intensive, posing challenges during emergencies.
    To address this, we proposed using electricity consumption (EC) and nighttime lights (NTL) datasets to estimate the total, commercial, and industrial economic losses from COVID-19 lockdowns in the Philippines. Regression models were employed to establish the relationship of GDP with EC and NTL. Then, models using basic statistics and weather data were developed to estimate the counterfactual EC and NTL, from which counterfactual GDP was derived. The difference between the actual and the counterfactual GDP from 2020 to 2021 yielded economic loss.
    This paper highlights three findings. First, the regression model results established that models based on EC (adj-R2 ≥ 0.978) were better at explaining GDP than models using NTL (adj-R2 ≥ 0.663); however, combining both EC and NTL improved the prediction (adj-R2 ≥ 0.979). Second, counterfactual EC and NTL could be estimated using models based on statistics and weather data explaining more than 81% of the pre-pandemic values. Last, the estimated total loss amounted to 2.9 trillion PhP in 2020 and 3.2 trillion PhP in 2021. More than two-thirds of the losses were in the commercial sector as it responded to both policies and the COVID-19 case surge. In contrast, the industrial sector was affected primarily by the lockdown implementation.
    This method allowed monitoring of economic losses resulting from long-term and large-scale hazards such as the COVID-19 pandemic. These findings can serve as empirical evidence for advocating targeted strategies that balance public health and the economy during pandemic scenarios.

    预期寿命可以反映气候政策的健康益处和实施成本。然而,文献中很少有研究量化预期寿命与气候政策之间的关系。在本文中,我们试图通过研究预期寿命与中国全国排放交易计划(CNETS)的关系来缩小研究差距。为了实现这一研究目标,采用可计算一般均衡(CGE)模型来模拟经济系统的运行和减排的政策冲击。CGE模型结果表明,预期寿命因GDP而延长,但因排放而缩短,GDP对预期寿命的影响大于排放影响。气候政策对预期寿命有双重影响,因为它既减轻了排放的负面影响,也减轻了GDP对寿命的积极影响;它对预期寿命的净影响是积极的。预期寿命对GDP有积极影响,这种影响受到气候政策的缓和;具体地说,气候政策加强了预期寿命对GDP的积极影响。在气候政策实施期间,预期寿命对碳排放的影响最小;换句话说,它对减排的影响最小。这些发现意味着气候政策和预期寿命是相辅相成的;政府可以实施气候政策来延长寿命或延长预期寿命,以促进政策实施。
    Life expectancy can reflect both health benefit and implementation cost of climate policy. Nevertheless, little research has quantified the relation between life expectancy and climate policy in literature. In this paper, we attempt to narrow the research gap by studying how life expectancy is related to the Chinese nationwide emission trading scheme (CNETS). To achieve this research target, a Computable General Equilibrium (CGE) model is employed to simulate the operation of the economic system and the policy shock from emission abatement. The CGE model results show that life expectancy is prolonged by GDP but shortened by emissions, and the GDP impact on life expectancy is larger than the emission impact. Climate policy has dual effects on life expectancy because it relieves both negative emission impacts and positive GDP impacts on lifespan; its net effect on life expectancy is positive. Life expectancy positively impacts GDP, and this impact is moderated by climate policy; specifically, climate policy reinforces the positive impact of life expectancy on GDP. Life expectancy minimally affects carbon emissions during climate policy implementation; in other words, it has minimal impacts on emission abatement. These findings imply that climate policy and life expectancy complement each other; the government could implement climate policy to increase lifespan or prolong life expectancy to facilitate policy implementation.

    本研究调查了金砖国家资本外逃的潜在决定因素。我们使用剩余法估计资本外逃,并采用GMM测试方法。我们发现金砖国家的资本外逃量激增,尤其是在全球金融危机之后。实证结果表明,资本外逃的过去价值,实际GDP增长率,汇率贬值,失业率,商业信心指数和金融稳定性指标是导致金砖国家居民资本外流的重要因素。这些发现要求财政和货币当局建立有效的政策框架。
    This study investigates the potential determinants of capital flight from BRICS countries. We use the residual method to estimate capital flight and employ GMM testing approach. We find a surge in the volume of capital flight from BRICS especially in the aftermath of global financial crisis. The empirical results suggest that, past values of the capital flight, real GDP growth rates, exchange rate depreciation, unemployment rate, business confidence index and financial stability indicator as significant factors causing resident capital outflows from BRICS nations. These findings call for an effective policy framework by the fiscal and monetary authorities.

    近年来,不断增加的二氧化碳(CO2)排放量和人类活动对环境的其他负面影响引起了人们对地球未来的担忧。快速工业化,城市化,经济活动显示二氧化碳排放量激增,导致全球变暖和气候变化。这项研究的主要目的是研究诸如国内生产总值,国内生产总值平方,外国直接投资,环境外交,环境外交安全,和可再生能源消费对环境退化的影响。本研究使用1991年至2020年的面板数据计量经济学方法,为OECD国家的环境外交提供了新的视角。它有助于我们了解环境和经济因素在减少二氧化碳排放中的作用。面板数据也通过CD分析,CIPS,FMOLS,娃娃,和PMG-ARDL测试。然而,根据这项研究的结果,所有因素都显著影响环境退化(Co2排放)。通过这种方法,可以在经合组织国家的框架内找到数据来确认或否认环境库兹涅茨曲线理论的有效性。该政策框架试图通过强调合作与可持续性并将环境因素纳入经合组织国家的经济决策过程来解决环境外交与经济关切之间的问题。
    In recent years, rising carbon dioxide (CO2) emissions and other negative environmental effects of human activity have raised concerns about the planet\'s future. Rapid industrialization, urbanization, and economic activity have shown a surge in CO2 emissions, contributing to global warming and climate change. The main purpose of this study is to examine the impact of such as gross domestic product, gross domestic product square, foreign direct investment, environmental diplomacy, environmental diplomacy security, and renewable energy consumption on environmental degradation. This study provides a new perspective on environmental diplomacy in OECD countries using panel data econometric methodologies from 1991 to 2020. It contributes to our understanding of the role of environmental and economic factors in reducing CO2 emissions. The panel data is also analyzed by CD, CIPS, FMOLS, DOLS, and PMG-ARDL tests. However, as per the findings of this research, all the factors significantly impact environmental degradation (Co2 emission). Finding data to either confirm or deny the efficacy of the Environmental Kuznets Curve theory within the framework of OECD countries is possible through this approach. This policy framework attempts to solve the issues at the connection of environmental diplomacy and economic concerns by emphasizing cooperation and sustainability and incorporating environmental considerations into economic decision-making processes in OECD countries.

    连接2030倡议,由国际电信联盟发起,符合联合国2030年议程的可持续发展目标。它的主要目标是实现通用连接,与环境问题密切相关的目标。该主题目前受到研究人员和政策制定者的关注。鉴于这些考虑,我们的研究调查了信息和通信技术对2009年至2020年84个国家的二氧化碳排放的影响。使用主成分分析,我们构建了一个包含国际带宽的ICT指数,反映了普遍的连通性,参与国际数据交换。实证分析应用了混合均值组面板自回归分布滞后(PMG-ARDL)方法来估计CO2排放决定因素的长期和短期系数。我们的研究结果表明,ICT和可再生能源可以减少二氧化碳排放,与金融发展不同,GDP,和不可再生能源,这对整个样本的排放有很大贡献。这些结果表明,在一般和国际带宽方面促进信通技术,作为通用连接的一部分,改善全球环境的质量。
    The Connect 2030 initiative, launched by the International Telecommunication Union, is in alignment with the Sustainable Development Goals (SDGs) of the United Nations Agenda 2030. Its main objective is to achieve universal connectivity, a goal that is closely related to environmental issues. This topic currently receives attention from researchers and policymakers. Given these considerations, our study investigates the impact of information and communication technologies on carbon dioxide emissions for a panel of 84 countries spanning the years 2009 to 2020. Using principal component analysis, we construct an ICT index that encompasses international bandwidth, reflecting the universal connectivity, and participation in international data exchanges. The empirical analysis applies the pooled mean group-panel autoregressive distributive lag (PMG-ARDL) approach to estimate both the long-run and short-run coefficients of CO2 emissions\' determinants. Our findings show that ICT and renewable energy mitigate CO2 emissions, unlike financial development, GDP, and non-renewable energy, which contribute significantly to emissions for the full sample. These outcomes suggest that promoting ICTs in general and international bandwidth in particular, as part of universal connectivity, improves the quality of the global environment.
