Summary: Ischemic stroke leads to white matter damage and neurological deficits. In this study, the characteristics of white matter injury and repair after stroke were investigated using a mouse stroke model. The researchers found that white matter damage was most severe on Day 7 after the stroke, and gradually recovered from Day 7 to Day 30. They also discovered that CD11c(+) microglia play critical roles in white matter repair and functional recovery after stroke. These findings suggest that spontaneous white matter repair occurs after ischemic stroke, with CD11c(+) microglia being key players in this restorative process.

Summary: This study used unsupervised multivariate pattern analysis to analyze a large sample of magnetic resonance imaging data, revealing coordinated patterns of white matter maturation during the early postnatal period and the contributions of microstructural indices. By comparing the findings with histological features, it provides a concise and effective representation of early postnatal white matter reorganization.

Summary: Mild traumatic brain injury (mTBI) is common in military personnel and is associated with age-related neurodegenerative disorders affecting white matter in the brain. Non-negative matrix factorization (NMF) was used to detect covarying patterns of fractional anisotropy (FA) associated with mTBI in a large dataset of military Veterans. The study showed significant age-dependent differences in WM alterations between Veterans with and without TBI, highlighting the importance of considering age in assessing the effects of mTBI.

Summary: MRI-based tractography is not widely used in brain tumor surgery due to method heterogeneity and lack of a turn-key system. This work evaluated the robustness and reliability of tractography results in healthy subjects, demonstrating promising potential for future validation and implementation in clinical populations.

Summary: This study aimed to identify potential risk factors associated with periventricular white matter injury (PVWMI) in term-born children with cerebral palsy (CP). The results showed that pregnancy complications, antenatal toxin exposure, perinatal infection, and perinatal adversity were associated with PVWMI in these children.

Summary: This study evaluated the influence of punctate white matter lesions (PWML) on long-term neurodevelopmental outcomes in preterm infants. The findings showed a correlation between PWML and motor delay, as well as between PWML and cognitive and behavioral outcomes. The severity and types of impairments were found to be related to the number and location of PWML.

Summary: In this study, the development of white matter in infants from 0 to 6 months was investigated using diffusion MRI and quantitative MRI measurements. The researchers found that the longitudinal relaxation rate (R1) of white matter increased over time, with faster development in less mature areas of white matter in newborns.

Summary: The study revealed significant changes in brain metabolites in both the hippocampus and cerebellum during the later post-natal period of male rats, including decreased taurine and increased glutamate in the hippocampus, as well as a constant increase in myo-inositol and choline-containing compounds. These findings suggest the importance of considering changes in neurometabolites beyond the conventionally accepted cut off for adulthood in experimental design and data interpretation in this animal model.

Summary: Prematurity disrupts brain development and network organization, leading to increased segregation and decreased integration capacity in preterm infants. Compared to full-term infants, preterm infants demonstrate delayed transition in brain network architecture and decreased connectivity strength in specific regions, potentially underlying behavioral and social cognition difficulties.

Summary: The study compares the image quality of 2D high-resolution image acquisition with 3D reconstruction from low-resolution images in neonatal subjects, finding that they have comparable quality for clinical and morphometric assessments, with no loss of anatomical details and similar edge definition. Quantitative assessments show the reconstructed images accurately detect fine anatomical structures and allow for comparable morphometric measurements.

Summary: Although low- and middle-income countries face a high burden of neonatal encephalopathy, there is limited evidence on prevention and management in these settings. Interventions based on high-income countries' evidence may not always be applicable to LMICs, and more research is needed to evaluate effective treatments specifically for these regions. Careful attention to supportive care is likely to improve outcomes until specific neuroprotective or neurorestorative therapies are available.

Summary: Fetal growth restriction (FGR) is mainly caused by suboptimal placental function, leading to limited nutrient and oxygen supply to the developing fetus, particularly affecting brain development. FGR results in altered brain morphology, disrupted connectivity, and region-specific brain network disturbances, which are associated with cognitive and behavioral impairments.

Summary: Research indicates that even during the newborn period, familiar music and unfamiliar music are processed differently by the brain. After music listening, functional connectivity between brain regions in all newborns is modulated. Premature infants exposed to music experience enhanced functional connectivity between brain regions after listening to music.

Summary: This study analyzed the T-2* anisotropy and T-2* decay of Achilles and patellar tendons using a variable-echo-time sequence. The results showed that changes in fiber-to-field angle significantly affected T-2* values, indicating the importance of being aware of T-2* anisotropy in quantitative T-2* mapping of tendons to avoid misinterpretation.

Summary: This study demonstrates that lactoferrin (Lf) supplementation attenuates acute and long-term cerebral injuries caused by hypoxia-ischemia in a dose-dependent manner. The optimal dose of 1 g/kg of Lf showed the best effects, reducing brain volume decreases and other detrimental effects. The research emphasizes the need for better understanding of Lf's effects and potential harmful effects on immature brains.
