Correlation analysis was performed to explore the correlation between fecal flora,Hcy, and depressive cognitive function.RESULTSElevated serum levels of Hcy were seen in patients with MDD compared to healthy individuals. Patients withMDD indicated significant decreases in cognitive scores (P < 0.001) in six modules: Speed of processing, workingmemory, visual learning, reasoning and problem-solving, social cognition, and total scores. Hcy levels showed anegative correlation with processing speed, social cognition, and total MDD scores (P < 0.05). Hcy was alsosignificantly negatively correlated with Alistipes, Ruminococcae, Tenericides, and Porphyromonas (P < 0.05).CONCLUSIONOur results highlight that Hcy was correlated with cognition and gut microbiome in MDD. This interaction may berelated to the physiological and pathological mechanisms underlying cognitive deficits in depression.展开更多

Differences in functional outcomes between stroke survivors with and without impaired cognition may be attributed to age, level of cognitive impairment, and severity of stroke. Materials and Methods: A retrospective secondary data analysis was conducted using health-related administrative data acquired from a Southwestern Ontario hospital’s stroke rehabilitation database. The aim was to explore potential linkages between post-stroke impaired cognition and functional gains, rehabilitation stays, and living settings after discharge from rehabilitation. Results: An aggregate sample of 393 males and 314 females subclassified as experiencing mild, moderate, and severe stroke was analyzed. At inpatient rehabilitation admission, 21.5% (n = 152) of these patients had no impaired cognition, 33.7% (n = 238) had mild impaired cognition, 22.2% (n = 157) had moderate impaired cognition, and 22.6% (n = 160) had severe impaired cognition. Cognitively impaired stroke patients were significantly (p 0.001) older, had (mostly) moderate to severe stroke with significantly (p = 0.012) more moderate cognitive impairment, had significantly (p 0.001) longer rehabilitation stays, and a high propensity for being discharged to longer-term care facilities compared to non-cognitively impaired patients. Conclusion: Presence of significant dissimilarity in rehabilitation stays and post-discharge destinations among stroke survivors with and without cognitive impairment is attributed to the age of the patient, level of cognitive impairment, and rigorous rehabilitation interventions.展开更多

文摘The emergence of embodied cognition theory has altered our traditional understanding of children’s language learning,emphasizing the close connection between the body,environment,and movement.This paper discusses the opportunities,challenges,and future directions of research on children’s language learning from the perspective of embodied cognition.It concludes that multisensory engagement can greatly improve children’s comprehension and memorization of language knowledge and that language acquisition is intimately tied to bodily perception,movement,and emotional experience.In addition,children’s language acquisition can also be effectively aided by embodied cognition techniques as multimedia aids,gesture and enactment,and imagery.Based on previous evidence,we propose an integrated language learning framework and a new relevance-integration taxonomy for children’s language learning from the perspectives of embodied cognition and cognitive load theories.In order to support the long-term growth of children’s language education,future research should focus more on the requirement of embodied language learning in the preschool-primary transition and optimize the teaching objectives and contents.

文摘In patients with Alzheimer’s disease,gamma-glutamyl transferase 5(GGT5)expression has been observed to be downregulated in cerebrovascular endothelial cells.However,the functional role of GGT5 in the development of Alzheimer’s disease remains unclear.This study aimed to explore the effect of GGT5 on cognitive function and brain pathology in an APP/PS1 mouse model of Alzheimer’s disease,as well as the underlying mechanism.We observed a significant reduction in GGT5 expression in two in vitro models of Alzheimer’s disease(Aβ_(1-42)-treated hCMEC/D3 and bEnd.3 cells),as well as in the APP/PS1 mouse model.Additionally,injection of APP/PS1 mice with an adeno-associated virus encoding GGT5 enhanced hippocampal synaptic plasticity and mitigated cognitive deficits.Interestingly,increasing GGT5 expression in cerebrovascular endothelial cells reduced levels of both soluble and insoluble amyloid-βin the brains of APP/PS1 mice.This effect may be attributable to inhibition of the expression ofβ-site APP cleaving enzyme 1,which is mediated by nuclear factor-kappa B.Our findings demonstrate that GGT5 expression in cerebrovascular endothelial cells is inversely associated with Alzheimer’s disease pathogenesis,and that GGT5 upregulation mitigates cognitive deficits in APP/PS1 mice.These findings suggest that GGT5 expression in cerebrovascular endothelial cells is a potential therapeutic target and biomarker for Alzheimer’s disease.

文摘BACKGROUND Cognitive impairment is one of the common clinical manifestations of depression,causing negative distress to patients.Elevated homocysteine(Hcy)concentrations and gut microbiome dysfunction may be observed in patients with depression.AIM To investigate the relationship between Hcy,microbiome,and cognition in depressive patients.METHODS We recruited 67 patients with major depressive disorder(MDD)(MDD group)and 94 healthy controls(HCs)individuals(HCs group).Serum Hcy levels were determined using the enzyme circulation method.16s rRNA sequencing was used to classify and identify the fecal bacteria.17 Hamilton depression rating scale and MATRICS consensus cognitive battery were used to evaluate mood states and cognition in patients with MDD. Correlation analysis was performed to explore the correlation between fecal flora,Hcy, and depressive cognitive function.RESULTSElevated serum levels of Hcy were seen in patients with MDD compared to healthy individuals. Patients withMDD indicated significant decreases in cognitive scores (P < 0.001) in six modules: Speed of processing, workingmemory, visual learning, reasoning and problem-solving, social cognition, and total scores. Hcy levels showed anegative correlation with processing speed, social cognition, and total MDD scores (P < 0.05). Hcy was alsosignificantly negatively correlated with Alistipes, Ruminococcae, Tenericides, and Porphyromonas (P < 0.05).CONCLUSIONOur results highlight that Hcy was correlated with cognition and gut microbiome in MDD. This interaction may berelated to the physiological and pathological mechanisms underlying cognitive deficits in depression.
文摘BACKGROUND Ischemic stroke(IS)survivors face an elevated risk of epileptic seizures,and recurrent seizures following the first episode often signal worsening functional outcomes.AIM To investigate risk factors associated with seizure recurrence after a first episode in patients with IS and explore their associations with cognitive function,anxiety,and depression.METHODS A total of 100 patients with IS admitted to Shaanxi Provincial People’s Hospital between January 2017 and January 2024 were enrolled in this study.After a 1-5-year follow-up,patients were categorized into recurrence(n=43)and nonrecurrence(n=57)groups.Their medical records were collected and analyzed using univariate and multivariate analyses to determine potential predictors of seizure recurrence.Variables with statistical significance in the univariate analysis were incorporated into a binary logistic regression model for multivariate analysis.The risk model’s predictive performance was evaluated using the receiver operating characteristic curve.How independent risk factors,identified in multivariate analysis,related to cognitive[Montreal Cognitive Assessment(MoCA)]and emotional[Self-Rating Anxiety Scale(SAS)/Self-Rating Depression Scale(SDS)]outcomes,were assessed.RESULTS Recurrent seizures were significantly associated with age,stroke severity(National Institutes of Health Stroke Scale),late-onset seizures,electroenceph-alogram abnormalities,cortical involvement,hemorrhagic infarction,and extensive cerebral infarctions,with lateonset seizures,cortical involvement,and hemorrhagic infarction serving as independent predictors.The risk model revealed an area under the curve of 0.732,with 88.37%specificity and 42.11%sensitivity.These three were also correlated with lower MoCA scores and higher SAS and SDS scores.CONCLUSION In patients with IS,recurrent seizures after the first episode can be independently predicted by late-onset seizures,cortical involvement,and hemorrhagic cerebral infarction-factors also correlating with cognitive impairment and emotional distress.These findings underscore the need for close clinical monitoring and targeted interventions(e.g.,cognitive rehabilitation and psychological support)to mitigate seizure recurrence in high-risk individuals.

文摘This paper aims to explore the cognition and demand of nature education.Through the analysis of its connotation,significance,current situation and challenges,corresponding countermeasures and suggestions are put forward.Nature education is a kind of education mode based on the natural environment,which enables learners to integrate with nature through scientific and effective means.This kind of education method has a far-reaching impact on shaping the overall quality of teenagers and cultivating the correct world outlook and values.By means of literature review,case analysis and other means,combined with the development practice of nature education at home and abroad,this study deeply analyzes the cognitive status and demand characteristics of nature education,which provides guidance and basis for the dissemination and development of nature education.
文摘The utilization of millimeter-wave frequencies and cognitive radio(CR)are promising ways to increase the spectral efficiency of wireless communication systems.However,conventional CR spectrum sensing techniques entail sampling the received signal at a Nyquist rate,and they are not viable for wideband signals due to their high cost.This paper expounds on how sub-Nyquist sampling in conjunction with deep learning can be leveraged to remove this limitation.To this end,we propose a multi-task learning(MTL)framework using convolutional neural networks for the joint inference of the underlying narrowband signal number,their modulation scheme,and their location in a wideband spectrum.We demonstrate the effectiveness of the proposed framework for real-world millimeter-wave wideband signals collected by physical devices,exhibiting a 91.7% accuracy in the joint inference task when considering up to two narrowband signals over a wideband spectrum.Ultimately,the proposed data-driven approach enables on-the-fly wideband spectrum sensing,combining accuracy,and computational efficiency,which are indispensable for CR and opportunistic networking.

文摘BACKGROUND Apolipoprotein E epsilon 4(APOE4)is recognized as a genetic risk factor for cognitive decline and neurodegeneration in both type 2 diabetes mellitus(T2DM)and Alzheimer’s disease,while glycated hemoglobin(HbA1c)reflects persistent hyperglycemia and serves as a key indicator of long-term glycemic control in T2DM.Although both factors have been individually linked to neurobehavioral deficits,it remains uncertain whether HbA1c contributes to APOE4-related cognitive and olfactory impairment in individuals with T2DM.AIM To investigate the role of HbA1c in APOE4-associated cognitive and olfactory dysfunction in patients with T2DM.METHODS Of 636 T2DM patients were recruited from five medical centers in Wuhan,Hubei Province,China.APOE genotyping was evaluated by polymerase chain reaction using Gerard’s method.Cognitive and olfactory functions were assessed by mini-mental state examination and Connecticut chemosensory clinical research center test,respectively.Regression analysis was employed to assess the independent and interactive effects of HbA1c on APOE4-associated cognitive and olfactory function.RESULTS APOE4 was associated with increased risks of cognitive impairment[odds ratios(OR)=1.815,P=0.021]and olfactory dysfunction(OR=2.588,P<0.001).Higher HbA1c levels were also related to worse cognitive(OR=1.189,P<0.001)and olfactory performance(OR=1.149,P=0.011).HbA1c exerted a moderating effect,yet not a mediating effect,between APOE4 and its impacts on cognition and olfaction.Specifically,a higher level of HbA1c exacerbated the damaging effect of APOE4,as shown by significant interaction effects on both cognitive impairment(OR=2.687,P<0.001)and olfactory dysfunction(OR=1.440,P=0.027).CONCLUSION Elevated HbA1c levels are associated with increased risks of cognitive and olfactory impairments in patients with T2DM and may exacerbate the detrimental effects of APOE4.These findings underscore the need for early preventive strategies targeting individuals with both poor glycemic control and APOE4 carriage to mitigate neurodegenerative risk.

文摘Artificial intelligence is currently achieving impressive success in all fields.However,autonomous navigation remains a major challenge for AI.Reinforcement learning is used for target navigation to simulate the interaction between the brain and the environment at the behavioral level,but the Artificial Neural Network trained by reinforcement learning cannot match the autonomous mobility of humans and animals.The hippocampus–striatum circuits are considered as key circuits for target navigation planning and decision-making.This paper aims to construct a bionic navigation model of reinforcement learning corresponding to the nervous system to improve the autonomous navigation performance of the robot.The ventral striatum is considered to be the behavioral evaluation region,and the hippocampal–striatum circuit constitutes the position–reward association.In this paper,a set of episode cognition and reinforcement learning system simulating the mechanism of hippocampus and ventral striatum is constructed,which is used to provide target guidance for the robot to perform autonomous tasks.Compared with traditional methods,this system reflects the high efficiency of learning and better Environmental Adaptability.Our research is an exploration of the intersection and fusion of artificial intelligence and neuroscience,which is conducive to the development of artificial intelligence and the understanding of the nervous system.

文摘Memory deficit,which is often associated with aging and many psychiatric,neurological,and neurodegenerative diseases,has been a challenging issue for treatment.Up till now,all potential drug candidates have failed to produce satisfa ctory effects.Therefore,in the search for a solution,we found that a treatment with the gene corresponding to the RGS14414protein in visual area V2,a brain area connected with brain circuits of the ventral stream and the medial temporal lobe,which is crucial for object recognition memory(ORM),can induce enhancement of ORM.In this study,we demonstrated that the same treatment with RGS14414in visual area V2,which is relatively unaffected in neurodegenerative diseases such as Alzheimer s disease,produced longlasting enhancement of ORM in young animals and prevent ORM deficits in rodent models of aging and Alzheimer’s disease.Furthermore,we found that the prevention of memory deficits was mediated through the upregulation of neuronal arbo rization and spine density,as well as an increase in brain-derived neurotrophic factor(BDNF).A knockdown of BDNF gene in RGS14414-treated aging rats and Alzheimer s disease model mice caused complete loss in the upregulation of neuronal structural plasticity and in the prevention of ORM deficits.These findings suggest that BDNF-mediated neuronal structural plasticity in area V2 is crucial in the prevention of memory deficits in RGS14414-treated rodent models of aging and Alzheimer’s disease.Therefore,our findings of RGS14414gene-mediated activation of neuronal circuits in visual area V2 have therapeutic relevance in the treatment of memory deficits.
文摘In recent years,embodied cognition has ushered in a new research upsurge in the academic field,and has become a hot topic in the field of cognitive psychology.In this paper,from the perspective of embodied cognition,the interaction ways of a landscape device for children were discussed to achieve a more real and harmonious interaction between children and scenes.The research data of embodied cognition used by children was analyzed,and the drawbacks and breakthrough points of current landscape devices for children were discussed.The core characteristics of children’s growth period were extracted to establish children’s interaction model and summarize the interactive design methods of landscape devices for children.Embodied cognition has become the most intuitive way for children to know and understand the environment,and plays a pivotal role in children’s growth.Based on embodied cognition principle and interactive behavior mode,the interactive design of a landscape device for children was studied,and three interactive design modes,including simple and convenient interaction mode,multi-sensory interaction mode and game natural interaction mode were summarized.On the basis of this research,relevant design practice and research were carried out to bring a new vision to the design of children’s landscape.
文摘Background: Stroke survivors who exhibit impaired cognition at admission to inpatient rehabilitation may experience participation challenges and poorer functional outcomes than those without impaired cognition. Differences in functional outcomes between stroke survivors with and without impaired cognition may be attributed to age, level of cognitive impairment, and severity of stroke. Materials and Methods: A retrospective secondary data analysis was conducted using health-related administrative data acquired from a Southwestern Ontario hospital’s stroke rehabilitation database. The aim was to explore potential linkages between post-stroke impaired cognition and functional gains, rehabilitation stays, and living settings after discharge from rehabilitation. Results: An aggregate sample of 393 males and 314 females subclassified as experiencing mild, moderate, and severe stroke was analyzed. At inpatient rehabilitation admission, 21.5% (n = 152) of these patients had no impaired cognition, 33.7% (n = 238) had mild impaired cognition, 22.2% (n = 157) had moderate impaired cognition, and 22.6% (n = 160) had severe impaired cognition. Cognitively impaired stroke patients were significantly (p 0.001) older, had (mostly) moderate to severe stroke with significantly (p = 0.012) more moderate cognitive impairment, had significantly (p 0.001) longer rehabilitation stays, and a high propensity for being discharged to longer-term care facilities compared to non-cognitively impaired patients. Conclusion: Presence of significant dissimilarity in rehabilitation stays and post-discharge destinations among stroke survivors with and without cognitive impairment is attributed to the age of the patient, level of cognitive impairment, and rigorous rehabilitation interventions.
文摘Inspired by Maurice Merleau-Ponty’s phenomenology of perception and the concept of“body-subject”,this study advances a new paradigm of“embodied”design thinking.This approach not only investigates how design can foster an organic connection between people and the world but also delves into the“embodiment of emotions”within design practices,thereby strengthening emotional resonance and empathy between design works and individuals.This transformation in design thinking holds significant importance for advancing and deepening research into design methodologies.The research aims to enhance the understanding of the intrinsic logic within design,aiding designers in creating works that resonate more profoundly with human daily productivity and life,and facilitating an emotional dialogue between the design and its users.Originating from a profound human-centered design philosophy and guided by Don Ihde’s theory of embodiment,the study begins with the functional relationships of bodily embodiment,employing phenomenological methods in design,enriched by in-depth case study analysis.Our research analysis has revealed three core logics of bodily embodiment in design:The logic of behavioral embodiment emphasizes innate and acquired human behavioral patterns;the logic of organ embodiment pertains to the interactions between internal organs and the external environment;and the logic of scenographic embodiment includes the design of empathetic scenes and subtler environmental layouts.In essence,this study underscores that modern design logic should consider the interplay between the human body,behavior,and the environment.Such Embodied Design logic offers new theoretical perspectives and guiding principles for future research and practical applications in design methodologies.

文摘In recent years,the suicide rate of adolescents has been increasing year by year,and life and health problems have become the most important in education.It is urgent to promote the construction of the curriculum of life education effectively.In view of the“vacuity”and“fragmented”state of traditional life education,this paper combs the teaching objectives,teaching contents,teaching methods,and teaching evaluation of life education from the perspective of embodied cognition theory,to explore the construction of positive experience of life education curriculum.
文摘Edutainment,in the kindergarten education stage,emphasizes the game as the basic activity and combines the content of education with the form of the game,thus it also forms the educational method of gamification teaching.Through investigation and analysis,it is found that the current kindergarten game activity design has the problem of improper combination of educational content and game form.The current kindergarten game activity design has problems such as stereotypes,children’s lack of active learning opportunities in activities,teachers’insufficient theoretical understanding,inappropriate teacher guidance methods,and so on.Embodied cognition theory attaches importance to the important role of the body in the development of cognition,provides new guidance for classroom teaching,and opens up a new path for classroom teaching reform.Based on the perspective of embodied cognition theory,the concept of body and mind integration should be adhered to in kindergarten teaching with games as the basic activity,experiential teaching situation should be created,children’s subjective experience should be respected,and games and interactions should be designed to promote children’s physical and mental participation,thus laying a foundation for the realization of children’s individual freedom,autonomy,and all-round development.Therefore,this paper aims at the existing problems in the current kindergarten gamification teaching and discusses the design strategy of children’s game activities based on embodied cognition theory.
文摘BACKGROUND Propofol and sevoflurane are commonly used anesthetic agents for maintenance anesthesia during radical resection of gastric cancer.However,there is a debate concerning their differential effects on cognitive function,anxiety,and depression in patients undergoing this procedure.AIM To compare the effects of propofol and sevoflurane anesthesia on postoperative cognitive function,anxiety,depression,and organ function in patients undergoing radical resection of gastric cancer.METHODS A total of 80 patients were involved in this research.The subjects were divided into two groups:Propofol group and sevoflurane group.The evaluation scale for cognitive function was the Loewenstein occupational therapy cognitive assessment(LOTCA),and anxiety and depression were assessed with the aid of the self-rating anxiety scale(SAS)and self-rating depression scale(SDS).Hemodynamic indicators,oxidative stress levels,and pulmonary function were also measured.RESULTS The LOTCA score at 1 d after surgery was significantly lower in the propofol group than in the sevoflurane group.Additionally,the SAS and SDS scores of the sevoflurane group were significantly lower than those of the propofol group.The sevoflurane group showed greater stability in heart rate as well as the mean arterial pressure compared to the propofol group.Moreover,the sevoflurane group displayed better pulmonary function and less lung injury than the propofol group.CONCLUSION Both propofol and sevoflurane could be utilized as maintenance anesthesia during radical resection of gastric cancer.Propofol anesthesia has a minimal effect on patients'pulmonary function,consequently enhancing their postoperative recovery.Sevoflurane anesthesia causes less impairment on patients'cognitive function and mitigates negative emotions,leading to an improved postoperative mental state.Therefore,the selection of anesthetic agents should be based on the individual patient's specific circumstances.
