Summary: The study found that age and sex have an impact on the cerebral white matter integrity of older adults, with a more significant effect on certain white matter tracts. Females exhibited lower global FA compared to males, but had higher MD in the anterior cingulum and superior longitudinal fasciculus. Age influenced both global FA and specific tract FA, while APOE epsilon 4 status did not show predictive power.

Summary: Using diffusion tensor tractography (DTT), this study explored the aging of the mesolibic tract (MLT) in normal human participants and found a significant negative correlation between age and the voxel number (VN) of MLT, as well as a positive correlation between age and the apparent diffusion coefficient (ADC). Aging of MLT was observed to begin in the 20s or 30s and steadily progress throughout life until significant degeneration occurred in the 60s. This may play a role in the decline of memory and social interaction with aging in normal participants.

Summary: ZOOMit DKI and CEST imaging can be valuable in predicting the WHO/ISUP grade and pathological T stage in ccRCC. Tumors with higher WHO/ISUP grades and pT stages tend to have lower ADC, MD, and S-sat (3.5 ppm)/S-0 values, while higher MK and MTRasym (3.5 ppm) values. The combination of MTRasym (3.5 ppm) and MD showed the best diagnostic performance for WHO/ISUP grading.

Summary: The study investigated cerebral white matter integrity in antipsychotic-naive, first-episode schizophrenia patients using diffusion tensor imaging (DTI) and magnetization transfer imaging (MTI. The results suggest disorganized white matter microstructure in patients, potentially related to neuroinflammation based on higher extracellular free-water concentrations in substance-free patients. Psychopathology was not significantly associated with the observed patterns, highlighting the importance of considering recreational substance use as a confounding factor in future white matter studies.

Summary: This study found that older participants had lower gray matter volumes in several brain areas, but these did not correlate with TBPM performance. On the other hand, a decline in white matter integrity was correlated with TBPM performance, indicating a disconnection process that occurs in aging and contributes to cognitive decline.

Summary: Diffusion tensor imaging provides increased sensitivity to microstructural tissue changes compared to conventional anatomical imaging, but presents limited specificity. To address this issue, the DIAMOND model subdivides voxel content into diffusion compartments and estimates compartmental non-central matrix-variate Gamma distributions of diffusion tensors. Incorporating tensor-valued diffusion encoding, the Magic DIAMOND model demonstrates improved accuracy in estimating brain microstructural features, particularly in regions of fiber crossing.

Summary: The study proposes the Compensation Related Utilization of Neural Circuits Hypothesis (CRUNCH) to explain the brain activity changes in healthy aging and task complexity. The findings suggest that all adults show increased brain activation with task complexity, older adults have more brain activation compared to younger adults at low complexity levels, and older adults are able to increase neural resources as task demands increase. These results indicate that older adults exhibit compensatory brain activation and maintain the capacity to adapt to task demands.

Summary: Aging is associated with structural and metabolic changes in the brain. Previous research has focused on individual brain regions, but the relationship among metabolites across the brain has been less studied. Using 1H-MRS, this study investigated the relationship among metabolite concentrations in different brain regions in young and older adults. The results showed age-related differences in metabolite concentrations and revealed associative patterns between metabolites across brain regions, which differed between age groups.

Summary: This study investigates the impact of training and testing condition differences on the predictions of a convolutional neural network (CNN) for myoelectric simultaneous and proportional control (SPC). A dataset of electromyogram (EMG) signals and joint angular accelerations recorded during a star drawing task was utilized. CNNs were trained using specific combinations of motion amplitude and frequency and tested under different combinations. The predictive performance was evaluated using normalized root mean squared error (NRMSE), correlation, and linear regression slope. The results showed that the predictive performance declined differently depending on the increase or decrease of confounding factors. Correlation decreased as the factors decreased, while slope deteriorated when the factors increased. NRMSE worsened in both increasing and decreasing factor scenarios. The study suggests that differences in EMG signal-to-noise ratio (SNR) between training and testing may affect the noise robustness of the CNNs' learned internal features, leading to worse correlations. Additionally, the inability of the networks to predict accelerations outside the training range may contribute to slope deterioration. These findings provide opportunities for developing strategies to mitigate the negative impact of confounding factors on myoelectric SPC devices.

Summary: This study explored the structural brain connectomes in children with spastic unilateral cerebral palsy (uCP) and its relationship to sensory-motor function using graph theory. The results showed a hyperconnectivity pattern in the CDGM-lesion group compared to the PWM-lesion group, with higher clustering coefficient, characteristic path length, and local efficiency. The CST-wiring pattern was found to be the strongest predictor for motor function. The findings highlight the potential of structural connectomics in understanding disease severity and brain development in children with uCP.

Summary: Cognitive impairment is a common issue after cancer treatment, and it negatively affects the quality of life for cancer survivors. This study investigated the potential of a mindfulness-based intervention to impact the mechanisms of cancer-related cognitive impairment (CRCI). Breast cancer survivors with cognitive complaints were assigned to a mindfulness, physical training, or waitlist control group. The results showed that physical training had the most pronounced effects on functional network organization and biomarkers of inflammation, which are believed to be involved in CRCI.
