DSCA: A Digital Subtraction Angiography Sequence Dataset and Spatio-Temporal Model for Cerebral Artery Segmentation [PDF]
Cerebrovascular diseases (CVDs) remain a leading cause of global disability and mortality. Digital Subtraction Angiography (DSA) sequences, recognized as the gold standard for diagnosing CVDs, can clearly visualize the dynamic flow and reveal pathological conditions within the cerebrovasculature.

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation
Advanced Materials Interfaces, EarlyView.Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Vascular co‐option and vasculogenic mimicry mediate resistance to antiangiogenic strategies
Cancer Reports, Volume 5, Issue 12, December 2022., 2022 Abstract Background The concept that all the tumors need the formation of new vessels to grow inspired the hypothesis that inhibition of angiogenesis would have led to “cure” cancer. The expectancy that this type of therapy would have avoided the insurgence of resistance was based on the concept that targeting normal vessels, instead of the cancer ...

Ultrasound Coded Vector Doppler Imaging of Blood Flow Velocity and
Resistivity, Acta Physica Sinica, vol. 74, no. 1, 2025Dynamic and precise measurement of cerebral blood flow velocity is crucial in neuroscience and the diagnosis of cerebrovascular diseases. Traditional color Doppler ultrasound can only measure the velocity component along the ultrasound beam, which restricts its ability to accurately capture the complete blood flow vector in complex environments.

Narrative Visualization to Communicate Neurological Diseases [PDF]
arXiv, 2022 While narrative visualization has been used successfully in various applications to communicate scientific data in the format of a story to a general audience, the same has not been true for medical data. There are only a few exceptions that present tabular medical data to non-experts.

MRI features of cerebral small vessel disease [PDF]
, 2019 Cerebral small vessel disease affects brain vessels with the smallest caliber - small arteries, arterioles, venules, capillaries. There is strong association with cognitive impairment, dementia, psychiatric conditions, gait disturbances. The main markers

Advanced Materials Interfaces, EarlyView.An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

Population Imaging of Cerebral Small Vessel Disease [PDF]
, 2012 As we grow older, our brain tends to shrink. We become increasingly vul nerable to dementia and stroke, two common disorders in the elderly that have great impact on brain functioning and the way people live their lives.
