We have compiled eight promising strategies for enhancing the specificity and selectivity of nanozymes,as depicted in the comprehensive summary above.Enzymes exhibit intricate and sophisticated structures,including substrate channels and active sites,which can inform the design of nanozymes.Replication of these structural features and the application of facet engineering/doping techniques can significantly enhance the catalytic specificity of nanozymes.Alternatively,the use of Molecularly Imprinted Polymers(MiPs)to coat nanozymes represents an effective approach to impart substrate specificity.Furthermore,several straightforward stopgap strategies have been devised to improve nanozyme specificity for analytical applications,such as the integration of biorecognition elements and nanozyme sensor arrays through surface modification.
This study utilized a longitudinal design to examine the relationships between the specific components of executive function(EF)and the internalizing and externalizing behavior across different genders and contexts in Chinese cultural background.Inhibition,cognitive flexibility,and working memory of EF based on 101 preschool children’s(48 boys and 53 girls)(M_(T1)=4.25,SD=0.76)performances were measured when completing tasks in NIH Toolbox.Twelve months later,boys’and girls’internalizing and externalizing behavior in home-and school-settings was assessed through mother’s feedback on the Strengths and Difficulties Questionnaire and teachers’reports of the Child Behavior Rating Scale.The results show that boys’inhibition,cognitive flexibility,and working memory negatively predict their externalizing behavior in the home context,while their cognitive flexibility negatively predicts externalizing behavior in the school context.Additionally,boys’inhibition positively predicts their internalizing behavior only in the school context.For girls,their cognitive flexibility positively predicts externalizing behavior only in the school context.No significant relationship is found among the girls between EF and problem behavior in the home context.These findings suggest that gender differences and a shift in contexts could alternate the relationship between EF and children’s problem behavior.This study sheds light on targeted preventions and interventions based on contexts and gender.
BACKGROUND Radiotherapy stands as a promising therapeutic modality for colorectal cancer(CRC);yet,the formidable challenge posed by radio-resistance significantly undermines its efficacy in achieving CRC remission.AIM To elucidate the role played by microRNA-298(miR-298)in CRC radio-resistance.METHODS To establish a radio-resistant CRC cell line,HT-29 cells underwent exposure to 5 gray ionizing radiation that was followed by a 7-d recovery period.The quantification of miR-298 levels within CRC cells was conducted through quantitative RT-PCR,and protein expression determination was realized through Western blotting.Cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and proliferation by clonogenic assay.Radio-induced apoptosis was discerned through flow cytometry analysis.RESULTS We observed a marked upregulation of miR-298 in radio-resistant CRC cells.MiR-298 emerged as a key determinant of cell survival following radiation exposure,as its overexpression led to a notable reduction in radiation-induced apoptosis.Intriguingly,miR-298 expression exhibited a strong correlation with CRC cell viability.Further investigation unveiled human dual-specificity tyrosine(Y)-regulated kinase 1A(DYRK1A)as miR-298’s direct target.CONCLUSION Taken together,our findings underline the role played by miR-298 in bolstering radio-resistance in CRC cells by means of DYRK1A downregulation,thereby positioning miR-298 as a promising candidate for mitigating radioresistance in CRC.
