Parent-child interaction as a dynamic contributor to learning and cognitive development in typical and atypical development / Influencia dinámica entre la interacción padre/madre-hijo y el aprendizaje y el desarrollo cognitivo en el desarrollo típico y atípico

Abstract

Converging evidence suggests that parent-infant interaction is one of the most crucial formative influences on child development. In neurodevelopmental disorders, however, different timings and trajectories of development may add a layer of difficulty to the existing challenges of dyadic interaction. The current study therefore set out to compare the specific aspects of dyadic interaction (i.e., responsiveness, directiveness, attentiveness, positive affect, liveliness, mutuality and engagement) between parent-infant dyads with Down syndrome, Williams syndrome and typical development. Video clips of parent-infant play interaction were rated using a validated tool, namely, the Social Interaction Measure for Parents and Infants. Significant effects emerged with respect to infant group on the quality of dyadic interaction, with the multiple comparison tests revealing differences between atypically and typically developing infant-parent dyads. The findings are discussed in relation to the effects of dyadic interaction on the linguistic and socio-cognitive development of atypical children.  相似文献   

Structural and physiological changes of the human body upon SARS-CoV-2 infection

Since December 2019, the novel coronavirus(severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)) has spread to many countries around the world, developing into a global pandemic with increasing numbers of deaths reported worldwide. To data, although some vaccines have been developed, there are no ideal drugs to treat novel coronavirus pneumonia(coronavirus disease 2019(COVID-19)). By examining the structure of the coronavirus and briefly describing its possible pathogenesis based on recent autopsy reports conducted by various teams worldwide, this review analyzes the possible structural and functional changes of the human body upon infection with SARS-CoV-2. We observed that the most prominent pathological changes in COVID-19 patients are diffuse alveolar damage(DAD) of the lungs and microthrombus formation,resulting in an imbalance of the ventilation/perfusion ratio and respiratory failure. Although direct evidence of viral infection can also be found in other organs and tissues, the viral load is relatively small. The conclusion that the injuries of the extrapulmonary organs are directly caused by the virus needs further investigation.  相似文献

ADP-ribosylhydrolases: from DNA damage repair to COVID-19     

Lily YU  Xiuhua LIU  Xiaochun YU 《Journal of Zhejiang University. Science. B》2021,22(1):21-30

Adenosine diphosphate(ADP)-ribosylation is a unique post-translational modification that regulates many biological processes,such as DNA damage repair.During DNA repair,ADP-ribosylation needs to be reversed by ADP-ribosylhydrolases.A group of ADP-ribosylhydrolases have a catalytic domain,namely the macrodomain,which is conserved in evolution from prokaryotes to humans.Not all macrodomains remove ADP-ribosylation.One set of macrodomains loses enzymatic activity and only binds to ADP-ribose(ADPR).Here,we summarize the biological functions of these macrodomains in DNA damage repair and compare the structure of enzymatically active and inactive macrodomains.Moreover,small molecular inhibitors have been developed that target macrodomains to suppress DNA damage repair and tumor growth.Macrodomain proteins are also expressed in pathogens,such as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).However,these domains may not be directly involved in DNA damage repair in the hosts or pathogens.Instead,they play key roles in pathogen replication.Thus,by targeting macrodomains it may be possible to treat pathogen-induced diseases,such as coronavirus disease 2019(COVID-19).  相似文献   

难美表现类项目动作失忆现象的机制及其心理特征     

徐晶妮  蒋小波 《军事体育进修学院学报》2011,30(4):112-115

运动失忆现象（Lost Move Syndrome）被定义为运动员一种失去身体位置知觉、特定技能动作的技术意识知觉的心理状况。此现象大多出现在体操、蹦床、跳水等动作复杂、难度高的项目中。这一现象的发生机制尚未清楚,重点综述和探讨了国外学者提出的意识控制破坏动作自动化假设、动作图式遭到破坏假设、动机压抑假设、缺乏社会支持...  相似文献   

导引养生功对失眠综合症治疗的效果研究     

周勇  张珂  仲卫朋  席永平  李靖 《吉林体育学院学报》2011,27(3):68-69

目的：观察导引养生功对失眠综合症的疗效。方法：采用实验法,将50例患者按性别、年龄及失眠程度相当随机均等的分为实验组和对照组,实验组进行导引养生功运动干预和心理暗示治疗;对照组只进行心理暗示治疗,疗程均为20周。结果：实验组和对照组的治疗都有效,但是在总效率改善方面,实验组更有效（P〈0.05）结论：通过观察治疗失眠综合症的过程,得出导引养生功结合心理暗示治疗能更有效的治疗失眠综合症。  相似文献
