    背景:目前缺乏用于诊断和监测嗜酸性粒细胞性食管炎(EoE)的非侵入性生物标志物。这项研究评估了血清和唾液中的20种生物标志物,旨在评估其在儿科EoE患者和健康个体中的诊断潜力。
    方法:对接受上消化道内窥镜检查的儿童的血液和唾液进行生物标志物分析,包括绝对嗜酸性粒细胞计数(AEC),嗜酸性粒细胞衍生神经毒素(EDN),总和特异性IgG4抗体(sIgG4),特异性IgE抗体(sIgE)和15-羟基二十碳四烯酸(15(S)-HETE)。一些患者参加了两次,形成一个纵向队列。评估了使用生物标志物预测EoE诊断的能力。
    结果:来自105名儿童的分析分为活跃的EoE,缓解,和健康,显示血清生物标志物水平升高(AEC,EDN,15(S)-HETE,与健康个体相比,活性EoE中的sIgG4和sIgE)。生物标志物的组合(AEC,EDN,sIgE对蛋清和小麦)和症状在区分三组时显示AUC为0.92。我们进一步表明,这些生物标志物的最佳截止值可以区分活性EoE和健康,在区分EoE(活性和缓解)与健康方面的敏感性为88%,特异性为100%。纵向,EDN的水平,sIgG4到Bosd4,Bosd5,Bosd8,麦醇溶蛋白,还有桦木,从活跃的EoE到缓解的患者中,sIgE对牛奶的降低(p<0.05)。
    结论:这项研究确定了与EoE相关的新型生物标志物,并提出了一个小组,连同症状,为了有效区分活跃的EoE,EoE在缓解,和健康的个体。这些发现可能有助于一种侵入性较小的诊断方法,并且可能是儿科EoE患者的潜在监视工具。
    BACKGROUND: Noninvasive biomarkers for diagnosing and monitoring eosinophilic esophagitis (EoE) are currently lacking. This study evaluates 20 biomarkers in serum and saliva, aiming to assess their diagnostic potential in pediatric EoE patients and healthy individuals.
    METHODS: Blood and saliva from children undergoing upper endoscopy were analyzed for biomarkers, including absolute eosinophil count (AEC), eosinophil-derived neurotoxin (EDN), total and specific IgG4-antibodies (sIgG4), specific IgE-antibodies (sIgE) and 15-hydroxyeicosatetraenoic acid (15(S)-HETE). Some patients participated twice, forming a longitudinal cohort. The ability to use the biomarkers to predict the EoE diagnosis was evaluated.
    RESULTS: Analysis from 105 children divided into active EoE, remission, and healthy, revealed elevated levels of serum biomarkers (AEC, EDN, 15(S)-HETE, sIgG4, and sIgE) in active EoE compared to healthy individuals. A combination of biomarkers (AEC, EDN, sIgE to egg white and wheat) and symptoms showed an AUC of 0.92 in distinguishing between the three groups. We further showed that optimal cutoff values for these biomarkers could discriminate between active EoE and healthy with a sensitivity of 88% and a specificity of 100% in distinguishing EoE (active and in remission) from healthy. Longitudinally, levels of EDN, sIgG4 to Bos d 4, Bos d 5, Bos d 8, gliadin, and birch, and sIgE to milk decreased in patients progressing from active EoE to remission (p <.05).
    CONCLUSIONS: This study identified novel biomarkers associated with EoE and proposes a panel, together with symptoms, for effective discrimination between active EoE, EoE in remission, and healthy individuals. The findings may contribute to a less invasive diagnostic method and may be a potential surveillance tool for pediatric EoE patients.

    目标:80岁以上的人很少符合Rowe和Kahn提出的成功衰老标准(SA)。超越个人层面的概念化,我们认为,SA始终在多种环境中运作,而在老年时期,这种环境可能变得最为关键。然而,我们不知道有任何先前的研究提供了一个经验测试的背景下,SA如何在80岁及以上的人群中展开,包括那些生活在机构中的人。
    方法:我们在对老年人进行的多项大型调查中,根据对SA的经典和丰富背景的理解,对成功衰老的患病率进行了估计和比较。即,D80+研究(N=3.233)和NRW80+研究(N[基线]=1.863)。除了跨独立样本复制之外,我们调查了上下文相关SA在不同时间的稳定性。
    结果:根据Rowe和Kahn的数据,在80-84岁的成年人中SA的患病率为9.1%,在90岁或以上的人群中为0.7%。然而,即使不符合Rowe和Kahn的标准,拥有良好环境的人的患病率在所有年龄组中都要高得多(80-84岁:54.9%,90岁及以上:44.4%)。与个人标准相比,在上下文中观察到了更大的两年稳定性。值得注意的是,与4岁晚期相比,发病时环境对SA的积极影响更强.
    结论:我们的发现支持对SA的情境化理解,并告知政策,在第四年龄段进一步发展SA需要在社区层面优化多种情境。
    OBJECTIVE: Few people who are ages 80+ meet the criteria of successful aging (SA) proposed by Rowe and Kahn. Going beyond the individual-level conceptualization, we argue that SA always operates in multiple contexts and that context may become most critical in advanced old age. However, we are not aware of any previous study providing an empirical test of how contexts for SA unfold across persons 80 years and older, including those living in institutions.
    METHODS: We estimated and compared prevalences of successful aging based on a classic versus context-enriched understanding of SA in multiple large surveys of older adults, i.e., the D80+ study (N = 3.233) and the NRW80+ study (N [baseline] = 1.863). In addition to replication across independent samples, we investigated the stability of context-related SA across time.
    RESULTS: Prevalences of SA according to Rowe and Kahn were 9.1% in adults aged 80-84 and 0.7% in persons 90 years or older. However, prevalence rates for those with good contexts at their disposal even if not fulfilling Rowe and Kahn\'s criteria were much higher across all age groups (80-84 years: 54.9%, 90 years and older: 44.4%). Greater two-year stability was observed for contextual compared to individual criteria. Notably, positive effects of context on SA were stronger at onset compared to late fourth age.
    CONCLUSIONS: Our findings support a contextualized understanding of SA and inform policy that furthering SA in the fourth age requires the optimization of multiple contexts at the community level.

    这里提出的工作是集成到PanAir的自动化前后处理器,这是一种基于高阶空气动力学面板方法的软件,用于70年代开发的流量分析,但仍在积极使用,尤其是用于飞机的初步设计。在这项工作中提出的集成环境,操作输入和输出数据和从PanAir成功绕过,否则需要手动操作和使用第三方软件。在具有改进的NLF(1)-0414机翼的塞斯纳210飞机上验证了集成环境。使用PanAir与集成环境一起分析了飞机周围的流量,结果表明,预处理和后处理时间减少,PanAir使用的便利性显着增加。
    The work proposed here is an automated pre and post-processor integrated to PanAir that is is a high-order aerodynamic panel method-based software for flow analysis developed in 70s but still in active use especially for preliminary aircraft design. With the integrated environment proposed in this work, manipulation of input and output data to and from PanAir is bypassed successfully that is otherwise requires manual manipulations and use of third party software. The integrated environment is validated over a Cessna 210 aircraft with a modified NLF (1)-0414 airfoil. The flow around the aircraft is analyzed using PanAir together with the integrated environment and results show that pre and post processing times reduced and ease in PanAir use is increased significantly.

    鲍曼不动杆菌是世界范围内最重要的病原体之一。鲍曼不动杆菌的内在和后天抗性,再加上新型抗菌药物开发的缓慢步伐,对鲍曼不动杆菌的临床抗感染治疗提出了前所未有的巨大挑战。致病性领域的最新研究,抗生素耐药性,鲍曼不动杆菌的生物膜集中在模型菌株上,包括ATCC17978、ATCC19606和AB5075。然而,这些模型菌株仅代表鲍曼不动杆菌异质性的有限部分。此外,这些模型菌株的变体已经出现,不仅在基因型水平上显示出显著的多样性,而且在胶囊的表型水平上也反映出差异,毒力,致病性,抗生素耐药性。鲍曼不动杆菌的研究,一个关键的病原体,将受益于标准化方法,它表征了异质菌株,以便于快速诊断,发现新的治疗靶点,和疗效评估。我们的研究提供并描述了一个标准化的,45种不同鲍曼不动杆菌菌株的基因组和表型异质性小组。此外,我们对该组的几种表型进行了比较分析.我们发现,序列2型(ST2)组表现出明显更高的耐药率,较低的适应健身成本,和更少的生物膜形成。E型大菌落(MTE,文献中报道的平坦中心和波浪形边缘表型)组显示出抗性率和生长速率之间不太明显的相关性,但被观察到产生更多的生物膜。我们的研究揭示了不同菌株中阻力适应性和生物膜形成的复杂相互作用,提供对对抗鲍曼不动杆菌感染至关重要的见解。
    目的:鲍曼不动杆菌在全球范围内臭名昭著,为了对抗这种病原体的传播,几种新兴的候选疗法已经浮出水面。然而,用于测试这些疗法的菌株在研究中有所不同(测试菌株的来源和数量各不相同,并且通常非常大,几乎没有异质性)。这种变化使研究复杂化。此外,鲍曼不动杆菌的标准化资源有限,极大地限制了其生理学研究,致病性,抗生素耐药性。因此,对于研究界来说,获得鲍曼不动杆菌的标准化和异质性小组至关重要。我们的研究从来自中国27个省的64个不同医院的总共2,197个临床分离株中精心选择了45个不同的鲍曼不动杆菌菌株。为研究界提供科学参考。这种援助将大大促进学术研究中的科学交流。
    Acinetobacter baumannii is one of the most important pathogens worldwide. The intrinsic and acquired resistance of A. baumannii, coupled with the slow pace of novel antimicrobial drug development, poses an unprecedented and enormous challenge to clinical anti-infective therapy of A. baumannii. Recent studies in the field of pathogenicity, antibiotic resistance, and biofilms of A. baumannii have focused on the model strains, including ATCC 17978, ATCC 19606, and AB5075. However, these model strains represent only a limited portion of the heterogeneity in A. baumannii. Furthermore, variants of these model strains have emerged that show significant diversity not only at the genotypic level but also reflected in differences at the phenotypic levels of capsule, virulence, pathogenicity, and antibiotic resistance. Research on A. baumannii, a key pathogen, would benefit from a standardized approach, which characterizes heterogeneous strains in order to facilitate rapid diagnosis, discovery of new therapeutic targets, and efficacy assessment. Our study provides and describes a standardized, genomically and phenotypically heterogeneous panel of 45 different A. baumannii strains for the research community. In addition, we performed comparative analyses of several phenotypes of this panel. We found that the sequence type 2 (ST2) group showed significantly higher rates of resistance, lower fitness cost for adaptation, and yet less biofilm formation. The Macrocolony type E (MTE, flat center and wavy edge phenotype reported in the literature) group showed a less clear correlation of resistance rates and growth rate, but was observed to produce more biofilms. Our study sheds light on the complex interplay of resistance fitness and biofilm formation within distinct strains, offering insights crucial for combating A. baumannii infection.
    OBJECTIVE: Acinetobacter baumannii is globally notorious, and in an effort to combat the spread of such pathogens, several emerging candidate therapies have already surfaced. However, the strains used to test these therapies vary across studies (the sources and numbers of test strains are varied and often very large, with little heterogeneity). The variation complicates the studies. Furthermore, the limited standardized resources of A. baumannii strains have greatly restricted the research on the physiology, pathogenicity, and antibiotic resistance. Therefore, it is crucial for the research community to acquire a standardized and heterogeneous panel of A. baumannii. Our study meticulously selected 45 diverse A. baumannii strains from a total of 2,197 clinical isolates collected from 64 different hospitals across 27 provinces in China, providing a scientific reference for the research community. This assistance will significantly facilitate scientific exchange in academic research.

    背景:透明细胞肾细胞癌(ccRCC)是影响泌尿系统的常见恶性肿瘤。由于其预后不良,迫切需要发现ccRCC的早期诊断和治疗的有效方法。广泛的研究一致证明了在人血清中存在稳定的微小RNA(miRNA)。因此,本研究的目的是鉴定血清中一组特定的miRNAs,这些miRNAs可以作为ccRCC早期检测的可靠且非侵入性的生物标志物.
    方法:该研究包括训练和验证阶段,以确定潜在的生物标志物。在训练阶段,使用定量逆转录聚合酶链反应(qRT-PCR),在28例ccRCC患者和28例健康对照(HCs)中鉴定出10种表现出最显著差异表达的miRNA.在随后的验证阶段,使用RT-qPCR评估了另外80例ccRCC患者和84例HC的血清样品中的这10种miRNA。要构建具有最佳诊断能力的面板,进行反向逐步logistic回归分析。此外,对该选定的miRNA组进行生物信息学分析.
    结果:在ccRCC患者中,与健康对照(HCs)相比,miRNA-142-5p的血清表达水平显着升高,而let-7f-5p的表达水平,miRNA-27b-3p,miRNA-212-3p,miRNA-216-5p显著降低。为了评估他们对ccRCC的诊断潜力,受试者工作特征(ROC)曲线分析。分析显示,miRNA-27b-3p,let-7f-5p,miRNA-142-5p对ccRCC表现出中等的诊断能力,曲线下面积(AUC)值分别为0.826、0.828和0.643。为了进一步提高诊断准确性,构建了由这三种miRNA组成的最终诊断小组,具有良好的诊断价值,AUC为0.952。
    结论:miRNA血清生物标志物组(miRNA-27b-3p,let-7f-5p,和miRNA-142-5p)在这项研究中鉴定出,非侵入性,ccRCC的准确诊断。该小组可能在临床环境中提供有价值的工具,以帮助及时检测和管理ccRCC。
    BACKGROUND: Clear cell renal cell carcinoma (ccRCC) is a prevalent malignant tumor affecting the urinary system. Due to its unfavorable prognosis, there is a pressing need to discover effective approaches for early diagnosis and treatment of ccRCC. Extensive research has consistently demonstrated the presence of stable microRNAs (miRNAs) in human serum. Accordingly, the objective of this study was to identify a specific panel of miRNAs in serum that can serve as a reliable and non-invasive biomarker for the early detection of ccRCC.
    METHODS: The study comprised of training and validation phases to identify potential biomarkers. In the training phase, a total of 10 miRNAs exhibiting the most significant differential expression among 28 ccRCC patients and 28 healthy controls (HCs) were identified using quantitative reverse transcription polymerase chain reaction (qRT-PCR). In the subsequent validation phase, these 10 miRNAs were assessed in serum samples obtained from an additional 80 ccRCC patients and 84 HCs using RT-qPCR. To construct a panel with optimal diagnostic capability, backward stepwise logistic regression analysis was conducted. Furthermore, bioinformatics analysis was performed on this selected miRNA panel.
    RESULTS: In ccRCC patients, the serum expression level of miRNA-142-5p was found to be significantly elevated compared to healthy controls (HCs), whereas the expression levels of let-7f-5p, miRNA-27b-3p, miRNA-212-3p, and miRNA-216-5p were significantly reduced. To assess their diagnostic potential for ccRCC, receiver operating characteristic (ROC) curve analysis was performed. The analysis revealed that miRNA-27b-3p, let-7f-5p, and miRNA-142-5p exhibited moderate diagnostic capabilities for ccRCC, with area under the curve (AUC) values of 0.826, 0.828, and 0.643, respectively. To further enhance diagnostic accuracy, a final diagnostic panel consisting of these three miRNAs was constructed, demonstrating good diagnostic value with an AUC of 0.952.
    CONCLUSIONS: The miRNA serum biomarker panel (miRNA-27b-3p, let-7f-5p, and miRNA-142-5p) identified in this study holds promise for early, non-invasive, and accurate diagnosis of ccRCC. This panel could potentially provide a valuable tool in clinical settings to aid in the timely detection and management of ccRCC.

    娱乐媒体内容经常被称为儿童不健康食品消费的根源之一。这可能是由于儿童媒体环境中存在大量不健康食品。然而,人们对食物放置中心的作用知之甚少,也就是说,食物是否相互作用,消费,口头提到,或者显得不显眼。我们也缺乏纵向研究来衡量儿童的不健康和健康食品消费行为作为结果。
    目的是将基于儿童实际媒体饮食的内容分析数据与面板数据联系起来,以解释儿童的食物偏好。此外,这项研究不仅关注儿童接触的健康和不健康食品的数量,还有这些食物是如何呈现的(即,中央或不中央)。此外,我们研究了父母共同观看如何减少(或增强)不健康(或健康)食物描绘的影响的问题,我们测量健康和不健康的消费作为因变量。
    我们对孩子及其父母之一进行了2波小组研究(与2250名父母联系,829回答,有效率为36.84%;648例有效病例,ie,父子对,用于分析),在2个面板波之间有6个月。我们将儿童及其父母的2波面板数据与儿童在6个月内接触的电影(n=113)和电视连续剧(n=134;每个电视连续剧使用3个随机选择的剧集)的内容分析数据相关联。
    随着时间的推移,暴露于不健康的食物呈现与不健康(b=0.008;P=.07)或健康(b=-0.003;P=.57)食物消耗之间没有显着关系。此外,随着时间的推移,健康食物的呈现与不健康(b=0.009;P=.18)或健康(b=0.000;P=.99)食物消耗无关.然而,有一个重要的,不健康食品的呈现与不健康食品消费的呈现中心性之间的正相互作用(b=0.000;P=0.03),这表明不健康食物呈现的影响随着中心性水平的增加而增加。不健康食品的呈现与健康食品消费的呈现中心之间没有相互作用(b=0.000;P=.10)。此外,暴露于健康食物呈现与中心性相互作用(b=-0.001;P=.003)。也就是说,当一个健康的产品以最大的中心地位呈现时,它减少了儿童不健康的食物消费。在解释不健康(b=0.003;P=.08)或健康(b=-0.001;P=.70)的食物消耗时,观察与不健康食物的暴露没有相互作用。
    我们得出的结论是,仅仅提供更多的健康食品不足以对抗儿童的不健康食品偏好。关于儿童媒体中不健康食品的陈述,可能需要进一步的监管。
    UNASSIGNED: Entertainment media content is often mentioned as one of the roots of children\'s unhealthy food consumption. This might be due to the high quantity of unhealthy foods presented in children\'s media environments. However, less is known about the role of the centrality of food placement, that is, whether foods are interacted with, consumed, verbally mentioned, or appear unobtrusively. We also lack longitudinal research measuring both children\'s unhealthy and healthy food consumption behaviors as outcomes.
    UNASSIGNED: The aim is to connect content analytical data based on children\'s actual media diet with panel data in order to explain children\'s food preferences. Moreover, this study not only focuses on the amount of healthy and unhealthy foods children are exposed to, but also on how these foods are presented (ie, centrally or not). Furthermore, we looked at the question of how parental coviewing can diminish (or enhance) the effects of unhealthy (or healthy) food depictions, and we measured healthy and unhealthy consumption as dependent variables.
    UNASSIGNED: We conducted a 2-wave panel study with children and one of their parents (of 2250 parents contacted, 829 responded, for a response rate of 36.84%; 648 valid cases, ie, parent-child pairs, were used for analysis), with 6 months between the 2 panel waves. We linked the 2-wave panel data for the children and their parents to content analytical data for movies (n=113) and TV series (n=134; 3 randomly chosen episodes per TV series were used) that children were exposed to over the course of 6 months.
    UNASSIGNED: There was no significant relationship between exposure to unhealthy food presentation and unhealthy (b=0.008; P=.07) or healthy (b=-0.003; P=.57) food consumption over time. Also, healthy food presentation was unrelated to unhealthy (b=0.009; P=.18) or healthy (b=0.000; P=.99) food consumption over time. However, there was a significant, positive interaction between unhealthy food presentation and presentation centrality on unhealthy food consumption (b=0.000; P=.03), suggesting that the effects of unhealthy food presentation rise with increasing levels of centrality. There was no interaction between unhealthy food presentation and presentation centrality on the consumption of healthy foods (b=0.000; P=.10). Also, exposure to healthy food presentation interacted with centrality (b=-0.001; P=.003). That is, when a healthy product was presented at maximum centrality, it led to less unhealthy food consumption in children. Coviewing did not interact with exposure to unhealthy foods when explaining unhealthy (b=0.003; P=.08) or healthy (b=-0.001; P=.70) food consumption.
    UNASSIGNED: We conclude that simply presenting more healthy foods is not sufficient to combat children\'s unhealthy food preferences. Further regulations may be necessary with respect to representations of unhealthy foods in children\'s media.

    本文的目的是双重的:分析美国能源消耗的平稳性,研究其周期和成对同步。我们研究了1973-2022年期间每月能源消耗的九个时间序列。系列中的四个(即煤炭,天然气,石油,和核电消耗)是不可再生能源,而其余的(水力发电,地热,生物量,太阳能,和风能消费)是可再生能源。我们使用非参数,面板平稳性测试方法。结果表明,大多数系列可能是趋势平稳性的,核能和地热能的消耗是唯一的例外。此外,进行了一系列能源消耗中潜在循环的研究,随后,我们分析了不同能源状态之间以及能源状态与商业周期之间的成对一致性。在后一种分析中检测到显著的相关性,对于化石燃料来源是积极的,对于两种可再生能源是消极的,即地热和生物质能消费。
    The purpose of this paper is twofold: analyzing stationarity of energy consumption by source in the United States and studying their cycles and pairwise synchronization. We study a panel of nine time series of monthly energy consumption for the period 1973-2022. Four of the series (namely coal, natural gas, petroleum, and nuclear electric power consumption) are non-renewables, whereas the remaining ones (hydroelectric power, geothermal, biomass, solar, and wind energy consumption) are renewable energy sources. We employ a nonparametric, panel stationarity testing approach. The results indicate that most of the series may be trend-stationarity, with nuclear and geothermal energy consumption being the only exceptions. Additionally, a study on potential cycles in the series of energy consumption by source is carried out, and subsequently we analyze pairwise concordance between states of different energy sources and between states of energy sources and the business cycle. Significant correlations are detected in the latter analysis, which are positive in the case of fossil fuel sources and negative for two renewable sources, namely geothermal and biomass energy consumption.
