Filter by:In this study, high-throughput screening and multi-omics (transcriptomics and proteomics) joint analysis technology will be employed to explore potential CTE/TES biomarkers (RNA and protein) in blood and its exosomes. Thereafter, these biomarkers will be combined with the reported TBI biomarkers to create a novel set of CTE/TES molecular diagnostic signatures. The findings may open a new avenue for the clinical diagnosis of the disease and the future research on its therapeutic strategy.
The objective of this study is to evaluate, using MRI, the microstructural consequences and the onset of any cognitive impairment in professional soccer players at the end of their career, who have experienced repeated minor head injuries. Over the long term, these head injuries could lead to morphological lesions and have an impact on soccer players' cognitive skills. The main evaluation criterion corresponds to the modifications found on MRI in the professional soccer player group (diffusion tensor, cerebral perfusion, fMRI, cerebral volumetry and cortical thickness, spectroscopy, susceptibility imaging). This is an exposure/nonexposure study assessing the onset of MRI abnormalities (diffusion tensor, cerebral perfusion, fMRI, volumetry and cortical thickness, spectroscopy, susceptibility imaging) in professional soccer players exposed to repeated mild head injuries, who are either at the end of their career or retired for approximately 10 years, compared to high-level athletes not exposed to head injuries.
As a common white matter (WM) disease in preterm neonates, punctate white matter lesion (PWML) frequently leads to the abnormalities of brain development (e.g. the motor, visual and auditory disorders), even to cerebral palsy (CP) and amblyopia during childhood. However, it is lack of certain methods in identifying the prognosis of PWML. Through using various advanced MRI techniques, neuro-behavioral and visual assessments, a multicenter longitudinal study would be conducted to follow-up the PWML neonates with varying spatial-position and degree lesions. Through tracking the variations in WM microstructures from neonate period to childhood (2 years old and 3 years old), this study aims to explore (1) the potential relations between varying PWMLs and motor and visual disorders (2) the relations between WM MRI-metrics and neurodevelopmental assessment results, and thus determine the early biomarkers to identify CP and amblyopia.
