Study on the optimal impact stand-off distance of self-excited pulsed supercritical carbon dioxide jet based on resonance effect

open access: yesMeitan xuebao
The supercritical carbon dioxide (SC-CO2) jet has a wide application prospect in drilling engineering, and its low coal breaking pressure threshold and high efficiency can improve drilling efficiency.

Genetic variation in the C-reactive protein gene and arterial stiffness: The Rotterdam Study

open access: yesArtery Research, 2008
Background and aim: Arterial stiffness increases with age and has been found to predict cardiovascular disease. C-reactive protein (CRP) is an inflammation marker and has been found to be associated with arterial stiffness and risk of cardiovascular ...

Hydrogel platforms for 3D cardiac tissue engineering and fibrotic disease modelling

open access: yesFEBS Open Bio, EarlyView.
Hydrogel‐based cardiac tissue models are advancing our understanding of heart health and disease. By incorporating electrical conductivity, aligned structures, and tunable mechanical properties, these platforms better replicate the complex environment of native heart tissue.

How to detect a positive response to a fluid bolus when cardiac output is not measured?

open access: yesAnnals of Intensive Care, 2019
Background Volume expansion is aimed at increasing cardiac output (CO), but this variable is not always directly measured. We assessed the ability of changes in arterial pressure, pulse pressure variation (PPV) and heart rate (HR) or of a combination of ...

Long‐Term Efficacy of Immunotherapy in Autoimmune Autonomic Ganglionopathy—A 10‐Year Follow Up Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune autonomic ganglionopathy (AAG) is a rare but potentially treatable cause of severe autonomic failure. Evidence guiding long‐term immunotherapy, treatment sequencing, and residual autonomic impairment is limited. We evaluated long‐term treatment response, residual autonomic dysfunction, and relapse patterns in patients with

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Pulse Pressure Variation Patterns in a Swine Model of Hypovolemia under Spontaneous Breathing vs. Invasive Positive-Pressure Ventilation

open access: yes, 2014
OBJECTIVE: This study was performed to obtain the title of Master in Medicine, Nov/2012-Jul/2013. Improvement in cardiac output after fluid administration is known as fluid responsiveness.

Variations in the effect of pulse pressure on cognition based on blood pressure

open access: yesThe Journals of Gerontology, Series B: Psychological Sciences and Social Sciences
Abstract Objectives This study examined the predictive utility of pulse pressure relative to blood pressure status for cognition among older adults and the potential differential effects of pulse pressure on cognition based on blood pressure status.

Boundary‐Dependent Sleep–Wake Dysregulation in Idiopathic Hypersomnia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

Patient-ventilator asynchrony affects pulse pressure variation prediction of fluid responsiveness

open access: yes, 2015
During partial ventilatory support, pulse pressure variation (PPV) fails to adequately predict fluid responsiveness. This prospective study aims to investigate whether patient-ventilator asynchrony affects PPV prediction of fluid responsiveness during ...
