Study of the blood supply of the brain in sheep

The Iraqi Journal of Veterinary Medicine, 1999
The brain of the sheep receives its blood supply through the carotid rete and the basilar artery. The carotid rete formed of contribution of internal carotid artery and branches from maxillary artery.

Endothelial BMP6 Drives Hemodynamic‐Dependent VSMCs Calcification in Carotid Atherosclerosis

Advanced Science, EarlyView.
The study demonstrates that endothelial cell (EC)‐derived BMP6 promotes the osteogenic differentiation of vascular smooth muscle cells (VSMCs) through cell‐cell interactions. Additionally, the researchers preliminarily explore the driving effect of hemodynamic factors on BMP6‐induced calcification and reveal the regulatory role of KLF4 on BMP6.

Regulation of Neuroinflammation by Microglial DUBA‐IRAK1‐IKKβ Signaling Loop

Advanced Science, EarlyView.
The protein levels of deubiquitinating enzyme A (DUBA) are rapidly upregulated in microglia after activation of Toll‐like receptor 4 (TLR4). In turn, DUBA potentiates TLR4‐induced proinflammatory signal transduction in microglia by stabilizing interleukin‐1 receptor activated kinase 1 (IRAK1) through K48 deubiquitination.

A Hypoxia‐Responsive Single‐Atom Sonozyme for Targeted Sonocatalytic Therapy in Alleviating Atherosclerotic Plaque

Advanced Science, EarlyView.
A tetranitrogen‐coordinated single‐atom manganese catalyst (SMC) is fabricated with outstanding sonosensitization efficiency and multi‐enzyme‐like catalytic properties. To enable better targeting of M1 macrophages, hyaluronic acid (HA) is applied to modify the surface of SMC, yielding SMC‐HA nanozymes.

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome

Advanced Science, EarlyView.
Shear‐activated nanoparticles carrying nitroglycerin selectively target high‐shear stress collateral vessels during ischaemic stroke, enhancing blood flow to at‐risk brain without systemic side effects. This novel approach significantly improves outcomes in animal models, outperforming conventional nitroglycerin delivery.
