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

International 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.

A Quantitative Comparison of Clinically Employed Parameters in the Assessment of Acute Cerebral Ischemia Using Dynamic Susceptibility Contrast Magnetic Resonance Imaging

Frontiers in Physiology, 2019
Purpose: Perfusion magnetic resonance imaging (P-MRI) is part of the mismatch concept employed for therapy decisions in acute ischemic stroke. Using dynamic susceptibility contrast (DSC) MRI the time-to-maximum (Tmax) parameter is quite popular, but its ...

Bionic Visual‐Auditory Perceptual System Based on Ionotronic Neuromorphic Transistor for Information Encryption and Decryption with Sound Recognition Functions

Advanced Electronic Materials, EarlyView.
A bionic visual‐auditory perceptual system is proposed. The system exhibits remarkable multi‐modal sensory abilities to sound and light, enabling diverse functions including encrypted sound information transmission and information decoding. The perceptual system can also perform sound recognition, resulting in the implementation of a sound lock ...

Tongxinluo enhances the effect of atorvastatin on the treatment of atherosclerosis with chronic obstructive pulmonary disease by maintaining the pulmonary microvascular barrier

Food Science &Nutrition, Volume 11, Issue 1, Page 390-407, January 2023., 2023
COPD aggravates AS, possibly through the destruction of pulmonary microvascular barrier function; thus, lung inflammation triggers systemic inflammation. In treating COPD with AS, TXL enhances the antiatherosclerotic effect of Ato, protecting the pulmonary microvascular barrier.

Calibrating Doppler imaging of preterm intracerebral circulation using a microvessel flow phantom

Frontiers in Human Neuroscience, 2015
Introduction. Preterm infants are born during critical stages of brain development, in which the adaptive capacity of the fetus to extra-uterine environment is limited. Inadequate brain perfusion has been directly linked to preterm brain damage. Advanced

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

Human 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.

Clinical outcomes of upfront combination therapy for portopulmonary hypertension

International Journal of Cardiology. Cardiovascular Risk and Prevention
Background: Limited data exists on upfront combination therapy for portopulmonary hypertension. We evaluated the clinical efficacy, long-term outcomes, and safety of upfront combination therapy in patients with portopulmonary hypertension.

HDL‐Apolipoprotein in Alzheimer's Disease Revisited: From Periphery to CNS

AGING MEDICINE, EarlyView.
HDL‐apolipoproteins in the periphery and CNS contribute differently to Alzheimer's disease, influencing Aβ, p‐tau, brain structures, and cognition. Apolipoprotein AI and E, key HDL components in blood and CSF, may either protect against or accelerate AD, depending on their location. Created with BioGDP.com. ABSTRACT High‐density lipoprotein (HDL), as a

Generalized models for quantifying laterality using functional transcranial Doppler ultrasound

Human Brain Mapping, Volume 44, Issue 1, Page 35-48, January 2023., 2023
Transcranial functional Doppler Ultrasound has been used to assess brain lateralization, but the methods used to extract a laterality index (LI) have involved simple averaging over a period of interest. Here, we compare results from that method with results from a generalized linear models (GLM) approach similar to that used in functional magnetic ...

Pharmacoeconomical assessment of сerebrolysin in the treatment of the acute disturbances of cerebral circulation

Фармакоэкономика, 2015
: the acute disturbances of cerebral circulation incidence accounts for nearly 70-80% of all such diseases in population, while this annual rate in Russian health care is about 2,19 cases on 1000 individuals. Pharmacoeconomic evaluation of this pathology
