Enhanced Embolic Signal Analysis through Ensemble Deep Learning Techniques Utilizing Transfer Learning and Layer Freezing Strategies

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 12, December 2025.
A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Electroacupuncture Prevents Against AD‐Like Phenotypes in APP/PS1 Mice: Investigation of the Mechanisms From Cerebral Microangiopathy

open access: yesCNS Neuroscience &Therapeutics, Volume 31, Issue 12, December 2025.
Electroacupuncture at combined acupoints GV20, CV4, and ST36 ameliorates AD‐like phenotypes, potentially through preventing microangiopathy and enhancing CBF. These findings provide novel insights for early intervention strategies to halt cognitive decline in AD.

The value of flow velocity alterations measured by carotid Doppler in the diagnosis of acute anterior ischemic stroke

open access: yesHong Kong Journal of Emergency Medicine, Volume 32, Issue 6, December 2025.
Abstract Background Acute ischemic stroke is a leading cause of mortality and long‐term disability. Conventional imaging methods like CT and MRI, while essential, are limited by cost, accessibility, and the need for patient transport. Carotid Doppler ultrasonography is a non‐invasive, low‐cost tool that can be performed bedside, yet its utility in ...

Advances in the study methods of cerebral venous sinus hemodynamics

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery
Cerebral venous system diseases can lead to idiopathic intracranial hypertension (IIH), cerebral venous thrombosis (CVT) and pulsatile tinnitus (PT), and accurate evaluation of cerebral venous sinus hemodynamics is very important for the diagnosis and ...

Integrative cardiovascular dose–response to graded lower‐body negative pressure

open access: yesExperimental Physiology, Volume 110, Issue 12, Page 1852-1879, December 1, 2025.
ABSTRACT Lower‐body negative pressure (LBNP) has been posited as a potential spaceflight countermeasure to counteract the physiological deconditioning related to fluid shifts in microgravity. However, open questions remain regarding the magnitude of LBNP that should be applied.

Hemodynamic predictors of early neurological deterioration and clinical outcome after endovascular treatment in large artery occlusion

open access: yesHeliyon
Objective: Half of the patients with acute large artery occlusion (LAO) have poor outcomes after endovascular treatment (EVT). Early complications such as cerebral edema and symptomatic intracranial hemorrhage (sICH) can lead to early neurological ...

A comparative analysis of transcranial Doppler parameters acquired during carotid stenting and semi-eversion carotid endarterectomy

open access: yesJornal Vascular Brasileiro
Background Carotid endarterectomy (CEA) and carotid artery stenting (CAS) have both been proposed for treatment of critical atherosclerotic stenosis located at the carotid bifurcation. Monitoring of hyperintense microembolic signals (MES) by transcranial
