Clinical and radiological features of cerebral venous thrombosis by the example of clinical cases

open access: yesКлинический разбор в общей медицине, 2023
Venous blood accounts for more than 80% of cerebral blood flow. At the same time, the incidence of cerebral venous thrombosis in patients with ischaemic stroke is only 3%.

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Why should we report posterior fossa emissary veins?

open access: yesDiagnostic and Interventional Radiology, 2014
Posterior fossa emissary veins are valveless veins that pass through cranial apertures. They participate in extracranial venous drainage of the posterior fossa dural sinuses.

Physical Intelligence in Small‐Scale Robots and Machines

open access: yesAdvanced Materials, EarlyView.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...
