Argon does not affect cerebral circulation or metabolism in male humans [PDF]

, 2017
Objective: Accumulating data have recently underlined argońs neuroprotective potential. However, to the best of our knowledge, no data are available on the cerebrovascular effects of argon (Ar) in humans.

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Effect of antenatal maternal anxiety on the reactivity of fetal cerebral circulation to auditory stimulation, and early child development [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2019
Introduction/Objective. Antenatal maternal anxiety (AMA) can have negative impact on a child’s preand postnatal development. The aim of the study was to examine the effect of AMA on changes in fetal blood flow through the middle cerebral artery (MCA ...

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

Directed Navigation of Magnetotactic Bacteria via Magnetotaxis in a 3D Vasculature‐On‐A‐Chip

Advanced Materials Technologies, EarlyView.
A perfusable vascular network is developed to investigate MTB at the single‐microorganism level. MTB is demonstrated to successfully align and navigate along the magnetic field inside the microvessels. Abstract Magnetotactic bacteria (MTB), inherently motile and self‐powered, are promising biorobotic candidates for targeted anti‐cancer drug delivery ...

Vascular Dynamics of Cerebral Gliomas Investigated with Selective Catheter Angiography, Perfusion CT and MRI [PDF]

, 2018
Purpose:: To assess if intratumoral blood circulation parameters from dynamic susceptibility contrast (DSC) MRI and dynamic CT deliver comparable results and to compare tumor-related changes in regional cerebral blood flow (rCBF) and regional cerebral ...

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

Advanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Fractal Analysis of Retinal Vessels and their Relationship with Cerebral Microcirculation Pathology – A Narrative Review

Applied Medical Informatics, 2020
One of the most reliable in vivo examination methods of human microvasculature is represented by ophthalmoscopy. Due to ophthalmoscopy, retinal circulation can reveal multiple morphological details that can serve as diagnosis biomarkers for retinal ...

ATF5‐Dependent GDF15 Expression Mediates Anesthesia‐Induced Neuroprotection Against Stroke

Advanced Science, EarlyView.
Anesthesia‐induced preconditioning protects against perioperative stroke. By manipulating ATF5 in excitatory neurons, it is shown that anesthesia‐driven ATF5 upregulation activates the mitochondrial unfolded protein response (UPRmt) and elevates GDF15 expression.

Evolutionary changes leading to efficient glymphatic circulation in the mammalian brain

Nature Communications
The functional significance of the morphological and genetic changes that occurred in the brain during evolution is not fully understood. Here we show the relationships between evolutionary changes of the brain and glymphatic circulation.
