Altered interactions between attentional networks in older adults with mild cognitive impairment.

Previous research using the Attention Network Test (ANT) paradigm has indicated that older adults with mild cognitive impairment (MCI) experience declines in attentional performance across the three core networks: alerting, orienting, and executive control, primarily focusing on main effects. The present study sought to expand these findings by exploring whether interactions between these networks are also affected in the presence of MCI. To achieve this, we used the Revised Attention Network Test (ANT-R) to examine both the individual attentional networks and their interactions in 21 older adults with MCI and 27 healthy controls (HCs) matched on demographic variables.

Elderly's Homesickness: Development of Elderly Homesickness Questionnaire.

Introduction: Homesickness is a result of migration, and is related to adjustment difficulties and health problems, as well as clinical disorders. The aim of this study was to measure and explore the homesickness of Chinese elderly.

Methods: A total of 355 non-local Chinese elderly in Shenzhen were recruited to measure demographic information and homesickness.

Design and simulation analysis of the AOTF full-Stokes imaging spectropolarimeter.

In order to effectively improve the contrast of target identification, an acousto-optic tunable filter (AOTF) full-Stokes imaging spectropolarimeter is proposed, which can measure synchronously polarization information with each spectral band in real time. The full-Stokes vectors are obtained by the division-of-aperture polarization imaging system. The spectral bands are selected by RF of the AOTF electrically.

The Associations of Meteorological and Environmental Factors with Memory Function of the Older Age in Urban Areas.

Individual, meteorological, and environmental factors are associated with cognitive function in older age. However, little is known about how meteorological and environmental factors interact with individual factors in affecting cognitive function in older adults. In the current study, we used mixed effects models to assess the association of individual, meteorological, and environmental factors with cognitive function among older adults in urban areas.

Multi-brightness layers with a genetic optimization algorithm for stereo matching under dramatic illumination changes.

Stereo matching under dramatic illumination changes is a big challenge in imbalanced binocular vision, self-driving cars, and the remote sensing image field. A novel, to the best of our knowledge, multi-brightness layer mechanism with a genetic optimization algorithm is proposed in this paper. The mechanism of multi-brightness layers transforms the two images with dramatic illumination changes into a series of matched pairs with similar brightness by the stretching function and histogram matching principle.

The Association of Meteorological Factors with Cognitive Function in Older Adults.

Individual and meteorological factors are associated with cognitive function in older adults. However, how these two factors interact with each other to affect cognitive function in older adults is still unclear. We used mixed effects models to assess the association of individual and meteorological factors with cognitive function among older adults.

The Weakened Relationship Between Prestimulus Alpha Oscillations and Response Time in Older Adults With Mild Cognitive Impairment.

Prestimulus alpha oscillations associated with preparatory attention have an impact on response time (RT). However, little is known about whether there is a deficit in the relationship between prestimulus alpha oscillations and RT in older adults with mild cognitive impairment (MCI). We collected electroencephalography (EEG) data from 28 older adults with MCI and 28 demographically matched healthy controls (HCs) when they were performing an Eriksen flanker task.

Reduced Capacity of Cognitive Control in Older Adults with Mild Cognitive Impairment.

Cognitive control for the coordination of mental operations is essential in normal cognitive functioning of daily life. Although the decline of cognitive control in older adults with mild cognitive impairment (MCI) has been demonstrated, whether this decline is a core deficit in MCI remains unclear. In this study, we employed a perceptual decision-making task to estimate the capacity of cognitive control (CCC) in older adults with MCI (n = 55) and the age-, sex-, and education-matched healthy controls (HC, n = 55) selected based on a commonly used battery of ten neuropsychological tests in five cognitive domains.

The relationship of anxious and depressive symptoms in Parkinson's disease with voxel-based neuroanatomical and functional connectivity measures.

Background: Anxiety and depression are two frequent comorbidities of Parkinson's disease (PD). However, the underlying neural mechanism is still unclear and the studies on their neural correlates were insufficient.

Methods: Using voxel-based neuroanatomical and functional connectivity (FC) measures, i.

Case report for recurrent and new-onset SLE patients treated by high-dose glucocorticoid therapy: Characteristics of peripheral TCR beta chain CDR3 repertoires.

Rationale: High-dose glucocorticoid therapy has been widely applied in clinical practice in systemic lupus erythematosus (SLE)patients, but less is known about the changes of T cells, especially the T cell receptor (TCR) repertoires, during the treatment. The aim of this paper is to describe the changes of TCR that recurrent and new-onset SLE patients treated by high-dose glucocorticoid therapy.

Patient Concerns: Drugs of clinical treatment of SLE mainly include glucocorticoid, immunosuppressive agents, nonsteroidal anti-inflammatory drugs and B cell targeted drugs, etc, but the clinical symptoms were in remission and recurrent of onset patients with SLE.
