Safety of positive gastrointestinal contrast media. Updated guidelines by the ESUR Contrast Media Safety Committee.
European radiology 36(7), 6007 - 6013 () [10.1007/s00330-026-12399-6]
Many reports on adverse effects related to positive gastrointestinal (GI) contrast media (CM) predate 2000; therefore, a literature review on their current safety profile was warranted. This article reviews the literature and updates the Contrast Media Safety Committee guidelines of the European Society of Urogenital Radiology on the safety of positive GI iodine-based and barium sulphate-based CM.

New neurons flatten social hierarchies.
As complex individualized behaviors in mice arise even when genes and environment are held constant, emerging social group structures should also depend on individual behavior. Adult hippocampal neurogenesis drives individual behavior and is involved in certain social behaviors. [...]

Sleep deprivation increases levels of the synaptic density marker SV2A in the human brain.
PLoS biology 24(6), e3003816 () [10.1371/journal.pbio.3003816]
Sleep is essential for synaptic homeostasis, a proposed mechanism whereby wakefulness leads to synaptic potentiation and sleep facilitates synaptic down-selection. Synaptic vesicle glycoprotein 2A (SV2A), whose availability is quantifiable by [¹⁸F]SynVesT-1 positron emission tomography (PET), is commonly interpreted as a proxy for synaptic density. [...]

Transitional Life Events in Friedreich Ataxia: Differential Age at Onset Perspectives.
Friedreich's ataxia (FA) is a rare, autosomal recessive neurodegenerative disease that primarily affects children and adolescents in their transition to adulthood, which is associated with several adverse life events caused by the disease progression. This article aims to describe life events associated with FA and their impact on patient-reported outcomes in pediatric and adult onsets. [...]

Circulating sphingosine-1-phosphate depletion is associated with endothelial activation and altered brain-endothelial S1P pathway expression in ischemic stroke.
Ischemic stroke remains a leading cause of disability and mortality worldwide, with limited acute therapeutic options. Sphingosine-1-phosphate (S1P) is a bioactive lipid that regulates endothelial function, vascular integrity, and immune responses, and reduced circulating S1P levels have been reported in ischemic stroke. [...]

Dataset: The retrotransposable element-silencing factor Daxx controls microglia identity and function in the adult brain
Gene Expression Omnibus ()
Death domain-associated protein (Daxx) is one of the two main H3.3 chaperones in mammalian cells and acts as key repressor of RTEs of viral origin. In present study, we found that Daxx is an IFN-stimulated gene mediating repression of RTEs and IFN-stimulated genes (ISGs) upon inflammatory stimuli in microglia. [...]

Default-mode network activity is retained in the isolated hemisphere of people after hemispherotomy.
Hemispherotomy is a surgical intervention for severe drug-resistant epilepsy that fully disconnects the lesional brain hemisphere from the rest of the nervous system. This creates a rare opportunity to explore whether consciousness can be sustained without external input. [...]
