Visual discomfort, neural inefficiency and the cortical haemodynamic response

Academia Biology
We show that visual perception of an image becomes uncomfortable when the image evokes a large haemodynamic response. The aversion of gaze that results therefore has the potential to reduce the use of energy by the brain.

To evaluate the effects of dexmedetomidine on intraocular pressure and haemodynamic changes in response to laryngoscopy and tracheal intubation

Journal of Neuroanaesthesiology and Critical Care, 2014
Background: The most important prerequisites for neurosurgeries are brain relaxation, need of stable haemodynamics with less fluctuation in intracranial pressure and speedy recovery from anaesthesia. Endotracheal intubation is the major stressful stimuli

Measuring Cerebral Activation From fNIRS Signals: An Approach Based on Compressive Sensing and Taylor-Fourier Model [PDF]

, 2016
Functional near-infrared spectroscopy (fNIRS) is a noninvasive and portable neuroimaging technique that uses NIR light to monitor cerebral activity by the so-called haemodynamic responses (HRs).

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

FEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

Hemodynamic response to endotracheal intubation using C-Trach assembly and direct laryngoscopy

Saudi Journal of Anaesthesia, 2015
Purpose: Our objective was to study the pressor response to endotracheal intubation through laryngeal mask airway C-Trach and compare it to the hemodynamic response to intubation with direct laryngoscopy (DL).

Microvascular dysfunction in the immediate aftermath of chronic total coronary occlusion recanalization [PDF]

, 2016
Objectives The aim of this study was to compare microvascular resistance under both baseline and hyperemic conditions immediately after percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) with an unobstructed reference vessel in ...

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Comparison of the effect of intravenous dexmedetomidine and lignocaine spray instilled into the endotracheal tube on extubation response in patients undergoing spine surgery

Journal of Neuroanaesthesiology and Critical Care, 2016
Background: In spine surgery rapid emergence and extubation with haemodynamic stability is crucial for early neurological examination. Here, we have studied the effect of α2 agonist – dexmedetomidine intravenous (IV) and lignocaine spray instilled into ...

The effects of locomotion on sensory-evoked haemodynamic responses in the cortex of awake mice

Scientific Reports, 2022
Investigating neurovascular coupling in awake rodents is becoming ever more popular due, in part, to our increasing knowledge of the profound impacts that anaesthesia can have upon brain physiology.
