Non‐invasive assessment of intracranial pressure

open access: yesActa Neurologica Scandinavica, 2016
Monitoring of intracranial pressure (ICP) is invaluable in the management of neurosurgical and neurological critically ill patients. Invasive measurement of ventricular or parenchymal pressure is considered the gold standard for accurate measurement of ...

Recent Advancements in Lung Cancer Metastasis Prevention Based on Nanostrategies

open access: yesAdvanced Science, EarlyView.
Metastasis is the leading cause of death in patients with lung cancer. Nanomedicine can be used to prepare efficient drug delivery systems owing to their advantages and plays an important role in the synergistic antimetastasis of lung cancer. This comprehensive review summarizes the emerging nanostrategies against lung cancer metastasis based on the ...

Construction of hybrid 1D‐0D networks for efficient and accurate blood flow simulations

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 262-312, February 2023., 2023
A set of coupling equations to appropriately couple nonlinear 1D and lumped‐parameter (0D) models for blood flow in compliant vessels is defined. Then, a methodology for the high‐order numerical coupling between 1D and 0D vessels through hybrid junctions is proposed.

Clinical Features of Pediatric Idiopathic Intracranial Hypertension and Applicability of New ICHD-3 Criteria [PDF]

open access: yes, 2018
Idiopathic intracranial hypertension (IIH) is characterized by intracranial pressure >28 cmH2O in the absence of identifiable causes. Aim of this paper is to describe the clinical phenotype of pediatric IIH and to analyze the applicability of ICHD-3 ...

The Awakening Brain is Characterized by a Widespread and Spatiotemporally Heterogeneous Increase in High Frequencies

open access: yesAdvanced Science, EarlyView.
This work explores the process of morning awakening of the human brain using polysomnography paired with simultaneous stereo‐electroencephalography, a method that provides high spatial and temporal resolution for examining brain activity. Awakening is characterized by an increase in high‐frequency spectral power and connectivity.

Measuring brain beats: Cardiac‐aligned fast functional magnetic resonance imaging signals

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 280-294, January 2023., 2023
Blood and cerebrospinal fluid (CSF) pulse and flow throughout the brain, driven by the cardiac cycle. We use rapid functional magnetic resonance imaging (fMRI) measurements to assess blood and CSF flow dynamics in a conventional 3 T magnetic resonance imaging scanner.

Phase synchronization in cerebral hemodynamics [PDF]

open access: yesarXiv, 2004
A healthy human brain is perfused with blood flowing laminarly through cerebral vessels, providing brain tissue with substrates such as oxygen and glucose. Under normal conditions, cerebral blood flow is controlled by autoregulation as well as metabolic, chemical and neurogenic regulation.

Non-invasive method of measuring cerebral spinal fluid pressure [PDF]

open access: yes, 2000
The invention provides a method of non-invasively determining intracranial pressure from measurements of an eye. A parameter of an optic nerve of the eye is determined, along with an intraocular pressure of the eye.

Intracranial Hemorrhage Due to Secondary Hypertension from Intracranial Large Vessel Occlusion [PDF]

open access: yes, 2020
Simultaneous hemorrhagic and ischemic strokes have been previously reported in the literature. Typically, these occur in patients secondary to dialysis, cerebral amyloid angiopathy, or thrombotic thrombocytopenic purpura.1,2,3 However, this is the unique
