A potential contributor to impaired motor imagery in amputees is an alteration of the body schema as a result of the presence of a phantom limb. However, the nature of the relationship between motor imagery and phantom experiences remains unknown. In this study, the influence of phantom limb perception on motor imagery was investigated using a hand mental(More)
Subjects may voluntarily implement an internal or external strategy during mental rotation (MR) task. However, few studies have reported the spatiotemporal differences of brain activation between the two MR strategies. This study aims to compare the two strategies from the perspective of behavioral performance and spatiotemporal brain activations in each(More)
To investigate the reorganization of functional brain network following amputation, twenty-two right-hand amputees and twenty-four age- and education-matched controls participated in a resting-state EEG study. EEG networks in alpha and beta bands were constructed using phase synchronization. Both global and local network parameters were compared between(More)
Depressed patients have a demonstrated cognitive bias in emotional information processing. However, it is unknown how early perceptual processing is modulated by emotional stimuli in depression. To examine this question, we studied 22 depressed patients and 22 healthy controls performing a cued target-response task with emotional facial expression as the(More)
OBJECTIVE Mental rotation of body parts involves sequential cognitive processes, including visual processing, categorization and the mental rotation process itself. However, how these processes are affected by the amputation of a limb is still unclear. METHODS Twenty-five right upper-limb amputees and the same number of matched healthy controls(More)
Long non-coding RNAs (lncRNAs) play a pivotal role in tumorigenesis, exemplified by the recent finding that lncRNA maternally expressed gene 3 (MEG3) inhibits tumor growth in a p53-dependent manner. Acute myeloid leukemia (AML) is the most common malignant myeloid disorder in adults, and TP53 mutations or loss are frequently detected in patients with(More)
Amputation of a limb induces changes in the so-called body schema, which might be influenced by the use of prosthetic devices. Changes in the body representation associated with prosthesis use could be investigated using a hand mental rotation task. However, direct neurophysiologic evidence for the effect of prosthesis use on hand mental rotation is still(More)
OBJECTIVE To compare of carotid-femoral pulse wave velocity (cf-PWV) and brachial-ankle PWV (ba-PWV) in the association with conventional cardiovascular risk factors and target organ damages (TODs).(Figure is included in full-text article.) DESIGN AND METHOD : 1599 community-dwelling elderly subjects (age>65 years old) in the northern Shanghai were(More)
Amputation of the dominant hand forces patients to use their non-dominant hand exclusively. Whether this chronic forced use of the non-dominant hand would affect the handedness preference remains an open question. In this study, the handedness preference in amputees was evaluated using a hand laterality judgment task by comparing recognition speeds of their(More)
