Gastrointestinal (GI) involvement in Lewy body diseases (LBDs) has been observed since the initial descriptions of patients by James Parkinson. Recent experimental and human observational studies raise the possibility that pathogenic alpha-synuclein (⍺-syn) might develop in the GI tract and subsequently spread to susceptible brain regions. The cellular and mechanistic origins of ⍺-syn propagation in disease are under intense investigation.

Background: The clinical manifestations of PI4KA-related disorders are characterized by considerable variability, predominantly featuring neurological impairments, gastrointestinal symptoms, and a combined immunodeficiency. The aim of this study was to delineate the novel spectrum of PI4KA variants detected prenatally and to assess their influence on fetal development.
Methods: A thorough fetal ultrasound screening was conducted, supplemented by both antenatal and post-abortion magnetic resonance imaging (MRI) studies.
Stress landscape of folding brain serves as a map for axonal pathfinding.

Understanding the mechanics linking cortical folding and brain connectivity is crucial for both healthy and abnormal brain development. Despite the importance of this relationship, existing models fail to explain how growing axon bundles navigate the stress field within a folding brain or how this bidirectional and dynamic interaction shapes the resulting surface morphologies and connectivity patterns. Here, we propose the concept of "axon reorientation" and formulate a mechanical model to uncover the dynamic multiscale mechanics of the linkages between cortical folding and connectivity development.

Objective: The aim of the present study is to examine the relationship between EEG measures and functional recovery in right-hemisphere stroke patients.
Methods: Participants with stroke (PS) and neurologically unimpaired controls (UC) were enrolled. At enrolment, all participants were assessed for motor and cognitive functioning with specific scales (motricity index, trunk control test, Level of Cognitive Functioning, and Functional Independence Measure (FIM).
Chryxanthone A, an extracted substance from endophytic fungal Aspergillus versicolor, produces anti-oxidant neuroprotection possibly via the action on mTOR/CREB axis.

Translational Medicine Center of Pain, Emotion and Cognition, Health Science Center, Ningbo University, Ningbo 315211 Zhejiang, China. Electronic address:
Background: Neurons are susceptible to oxidative stress due to the elevated reactive oxygen species (ROS) production and the limited antioxidant defense mechanisms. Therefore, it is possible to treat oxidative stress-related neurological disorders via the inhibition of oxidative stress. Chryxanthone A is an extracted substance derived from the endophytic fungal Aspergillus versicolor, with an atypical dihydropyran ring.
