Predictive haemodynamics in a one-dimensional human carotid artery bifurcation. Part II: application to graft design [PDF]

, 2008
A Bayesian surrogate modelling technique is proposed that may be able to predict an optimal bypass graft configuration for patients suffering with stenosis in the internal carotid artery (ICA). At the outset, this statistical technique is considered as a

The contribution of the external carotid artery to cerebral perfusion in carotid disease [PDF]

Journal of Vascular Surgery, 2000
In the presence of carotid occlusion, the external carotid artery (ECA) becomes an important source of cerebral blood flow, especially if the circle of Willis is incomplete. The contribution of the ECA to hemispheric blood flow in patients with severe ipsilateral carotid stenosis has never been previously investigated.One hundred eight patients were ...

A Photo‐Patternable Solid‐State Electrolyte for High‐Performance, Miniaturized, and Implantable Organic Electrochemical Transistor‐Based Circuits

Advanced Materials, EarlyView.
A photo‐patternable solid‐state electrolyte based on 𝜄‐carrageenan (𝜄‐CGN) and poly(ethylene glycol) diacrylate (PEGDA) is developed to enable high‐performance complementary OECT circuits. The successful demonstration of fully implanted devices for vagus nerve stimulation in mice highlights solid‐state 𝜄‐CGN‐based electrolytes as a promising platform ...

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Succinate Dehydrogenase Subunit A (SDHA) Mediated Microglia Extracellular Traps Formation Participating in Cerebral Ischemic Reperfusion Injury

Advanced Science, EarlyView.
This study investigates the mechanism of succinate dehydrogenase (SDH)‐mediated succinate oxidation in microglia extracellular traps (MiETs) formation and neuronal injury after cerebra I/R injury. Dimethyl malonate (DMM), a competitive SDH inhibitor, could reduce MiETosis by inhibiting succinate oxidation and mtROS production during reperfusion ...

An alternative surgical approach reduces variability following filament induction of experimental stroke in mice

Disease Models & Mechanisms, 2017
Animal models are essential for understanding the pathology of stroke and investigating potential treatments. However, in vivo stroke models are associated, particularly in mice, with high variability in lesion volume.

Human iPSC‐Derived Mononuclear Phagocytes Improve Cognition and Neural Health across Multiple Mouse Models of Aging and Alzheimer's Disease

Advanced Science, EarlyView.
Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.
