In the acute stage of stroke, stress hyperglycemia is common in both diabetic and nondiabetic patients. The associations between stress hyperglycemia and functional outcomes, as well as stroke recurrence were heterogeneous in previous studies. We aimed to demonstrate these associations in a general population of patients with ischemic stroke and transient ischemic attack (TIA).

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

The sub-ventricular zone (SVZ) is the most well-characterized neurogenic area in the mammalian brain. We previously showed that in 65% of patients with glioblastoma (GBM), the SVZ is a reservoir of cancer stem-like cells that contribute to treatment resistance and the emergence of recurrence. Here, we build a single-nucleus RNA-sequencing-based microenvironment landscape of the tumor mass and the SVZ of 15 patients and two histologically normal SVZ samples as controls.

We propose a novel approach to investigate the brain mechanisms that support coordination of behavior between individuals. Brain states in single individuals defined by the patterns of functional connectivity between brain regions are used to create joint symbolic representations of brain states in two or more individuals to investigate symbolic dynamics that are related to interactive behaviors. We apply this approach to electroencephalographic data from pairs of subjects engaged in two different modes of finger-tapping coordination tasks (synchronization and syncopation) under different interaction conditions (uncoupled, leader-follower, and mutual) to explore the neural mechanisms of multi-person motor coordination.

Background: Stress during pregnancy and postpartum periods has been associated with short-term cognitive deficits with potential long-term Alzheimer's disease (AD) risk. However, the biological mechanisms mediating these effects remain poorly understood. This study investigated the impacts of recurrent heat and simulated refugee camp stress across pregnancy and the postpartum period on cognition, affective behaviour, and AD neuropathological changes in primiparous rats.
