The widespread nitrogen oxides(NOx,mainly in NO)in the atmosphere have threatened human health and ecological environment.The dilute NO(ppb)is difficult to efficiently remove via the traditional process due to its characteristics of low concentration,wide range,large total amount,etc.Photocatalysis can utilize solar energy to purify NO pollutants under mild conditions,but its application is limited due to the low selectivity of nitrate and poor activity of NO removal.The underlying reason is that the interface mechanism of NO oxidation is not clearly understood,which leads to the inability to accurately regulate the NO oxidation process.Herein,the recent advances in the photocatalytic oxidation of NO are summarized.Firstly,the common strategies to effectively regulate carrier dynamics such as morphology control,facet engineering,defect engineering,plasma coupling,heterojunction and single-atom catalysts are discussed.Secondly,the progress of enhancing the adsorption and activation of reactants such as NO and O_(2) during NO oxidation is described in detail,and the corresponding NO oxidation mechanisms are enumerated.Finally,the challenges and prospects of photocatalytic NO oxidation are presented in term of nanotechnology for air pollution control.This review can shed light on the interface mechanism of NO oxidation and provide illuminating information on designing novel catalysts for efficient NOx control.

Developing a mucosal vaccine against SARS-CoV-2 is critical for combatting the epidemic.Here,we investigated long-term immune responses and protection against SARS-CoV-2 for the intranasal vaccination of a triple receptor-binding domain(RBD)scaffold protein(3R-NC)adjuvanted with a flagellin protein(KFD)(3R-NC+KFDi.n).In mice,the vaccination elicited RBD-specific broad-neutralizing antibody responses in both serum and mucosal sites sustained at high level over a year.This long-lasting humoral immunity was correlated with the presence of long-lived RBD-specific IgG-and IgA-producing plasma cells,alongside the Th17 and Tfh17-biased T-cell responses driven by the KFD adjuvant.Based upon these preclinical findings,an open labeled clinical trial was conducted in individuals who had been primed with the inactivated SARS-CoV-2(IAV)vaccine.With a favorable safety profile,the 3R-NC+KFDi.n boost elicited enduring broad-neutralizing IgG in plasma and IgA in salivary secretions.To meet the challenge of frequently emerged variants,we further designed an updated triple-RBD scaffold protein with mutated RBD combinations,which can induce adaptable antibody responses to neutralize the newly emerging variants,including JN.1.Our findings highlight the potential of the KFD-adjuvanted triple-RBD scaffold protein is a promising prototype for the development of a mucosal vaccine against SARS-CoV-2 infection.

Male pseudohermaphroditism is a rare disorders of sex development(DSD)that is manifested by a female-like appearance or incompletely differentiated external genitalia in an individual with a Y chromosome.In this paper,we report our investigation of the case of a 33-year-old Chinese female who was diagnosed with a malignant mixed germ-cell tumor of the ovary.To confirm the sex of the female,we utilized genetic approaches to detect amelogenin and Y-STR loci.Y chromosome microdeletion was performed to identify existing deletions in the AZF regions and SRY.Chromosome karyotyping and whole-exome sequencing(WES)were then applied to reveal the deletion of sex chromosome segments and pathogenic variations in DNA sequences.Using DNA-STR genotyping,we detected both AMEL-X and AMEL-Y fragments.We also found haplotype Y-STR loci and detected all alleles.Furthermore,no microdeletion was detected in the AZF regions and SRY.The chromosome karyotyping was 46,XY.WES revealed a transversion mutation of 58T→C in the androgen receptor exon 1,which could be the pathogenic variant in this case of abnormal sexual development.Sex determination in forensic DNA typing is based on the amelogenin system.It is important that forensic biologists should master various genetic approaches to overcome the issue of gender ambiguity caused by DSDs.

中小学校评价作为教育治理的重要环节,是学校改革的关键突破点,亦是教育高质量发展的保障。在我国中小学校评价全面实施的过程中,评价理念从效率优先转向强调质量、评价话语从分散模糊转向科学规范、评价内容从松散单一转向系统多元、评价机制从凝闭独白转向开放对话。为更加有效推进中小学校评价高质量发展,破除“唯分数”“唯升学”等限制性导向,应高度重视评价中的价值偏差、主体失衡、关系缺位、方法阻隔等关键问题,在价值论上持守“人本”底色、提倡价值“多维”,在主体论上凸显“治理”实效、推进“实质性参与”,在关系论上迈向“关系”联通、弥合互动间隙,在方法论上助推深度融合、实现数字“赋能”。

草酸钴合成过程是钴湿法冶炼的关键单元操作,其粒度分布是重要的质量指标,然而难以在线实时测量。同时,草酸钴合成过程通常存在非线性、多约束和慢时变特征。因此,提出一种集成慢特征分析(slow feature analysis,SFA)与最小二乘支持向量回归(least square support vector regression,LSSVR)的草酸钴粒度预报模型对草酸钴合成过程质量指标实现在线测量。在该方法中,首先,SFA方法可以有效地捕获过程的慢特征向量,解决慢时变问题;然后,利用LSSVR方法建立慢特征与粒度之间的非线性关系模型,进而实现质量指标在线预报。最后,应用非线性的数值案例以及草酸钴合成过程数据,验证该方法的有效性。实验结果显示:相较于单一的径向基函数神经网络(radial basis function neural network,RBFNN)、LSSVR预测模型以及SFA与NN相结合的预报模型,所提方法在数值案例中的预测精度分别提升了13.31%、2.26%、1.72%;在草酸钴合成过程中的预测精度分别提升了13.27%、9.96%、8.92%。

DearEditor,Indole-3-carboxaldehyde(ICA)is a gut microbe-derived tryptophan metabolite.Here,we explored the role of ICA in atherosclerosis.Plasma tryptophan metabolites were measured in healthy individuals and patients with atherosclerosis(Supplementary Table S1).The latter group showed disturbed tryptophan metabolism,while no difference was observed in tryptophan levels between the two groups(Fig.1a).ICA concentration is lower in the patients group(Fig.1b),consistent with previous clinical studies.1 The concentration of other metabolites of kynurenine or serotonin pathway showed no variations between the control and the patients(Supplementary Fig.1a).
