Cytokinesis-Blocking Micronucleus Assay for Assessing Nuclear Chromatin Integrity Abnormalities in Dog's Somatic Cells After Exposure to HVAD-Produced Silver Nanoparticles.

The widespread use of silver nanoparticles in many industries is increasing every year. Along with this use, there is growing concern about the potential unintentional exposure of human and animal organisms to these nanomaterials. It has been shown that AgNPs have the ability to penetrate organisms and can have harmful effects on cells and organs in the body.

The impact of controlled breathing on autonomic nervous system modulation: analysis using phase-rectified signal averaging, entropy and heart rate variability.

The present study investigated how breathing stimuli affect both non-linear and linear metrics of the autonomic nervous system (ANS).The analysed dataset consisted of 70 young, healthy volunteers, in whom arterial blood pressure (ABP) was measured noninvasively during 5 min sessions of controlled breathing at three different frequencies: 6, 10 and 15 breaths min. COconcentration and respiratory rate were continuously monitored throughout the controlled breathing sessions.

Analysis of phase shift between pulse oscillations of macro- and microvascular cerebral blood flow in patients with traumatic brain injury.

Purpose: After a traumatic brain injury (TBI), monitoring of both macrovascular and microvascular blood circulation can potentially yield a better understanding of pathophysiology of potential secondary brain lesions. We investigated the changes in phase shift (PS) between cardiac-induced oscillations of cerebral blood flow (CBF) measured at macro (ultrasound Doppler) and microvascular (laser Doppler) level. Further we assessed the impact of intracranial pressure (ICP) on PS in TBI patients.

Advanced neuromonitoring powered by ICM+ and its place in the Brand New AI World, reflections at the 20th anniversary boundary.

Introduction: Adoption of the ICM+® brain monitoring software by clinical research centres worldwide has been continuously growing over the past 20 years. This has necessitated ongoing updates to accommodate evolving neuromonitoring research needs, including recent explosion of artificial intelligence (AI).

Research Question: We sought to provide an update on the current features of the software.

Quantitative analysis of similarity between cerebral arterial blood volume and intracranial pressure pulse waveforms during intracranial pressure plateau waves.

Introduction: Both intracranial pressure (ICP) and cerebral arterial blood volume (CBV) have a pulsatile character related to the cardiac cycle. The evolution of the shape of ICP pulses under increasing ICP or decreasing intracranial compliance is well documented. Nevertheless, the exact origin of the alterations in the ICP morphology remains unclear.
