Early Detection of Alzheimer’s Disease Using Non-invasive Near-Infrared Spectroscopy

Frontiers in Aging Neuroscience, 2018
Mild cognitive impairment (MCI) is a cognitive disorder characterized by memory impairment, wherein patients have an increased likelihood of developing Alzheimer’s disease (AD).

Cortical pain responses in human infants [PDF]

, 2006
Despite the recent increase in our understanding of the development of pain processing, it is still not known whether premature infants are capable of processing pain at a cortical level.

Oral premedication with pregabalin or clonidine for hemodynamic stability during laryngoscopy and laparoscopic cholecystectomy: A comparative evaluation

Saudi Journal of Anaesthesia, 2011
Background: Hemodynamic responses of laryngoscopy and laparoscopy should be attenuated by the appropriate premedication, smooth induction, and rapid intubation.

Goal-directed therapy in intraoperative fluid and hemodynamic management. [PDF]

, 2013
Intraoperative fluid management is pivotal to the outcome and success of surgery, especially in high-risk procedures. Empirical formula and invasive static monitoring have been traditionally used to guide intraoperative fluid management and assess volume

A Systematic Comparison of Motion Artifact Correction Techniques for Functional Near-Infrared Spectroscopy

Frontiers in Neuroscience, 2012
Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp. These artifacts can be very damaging to the utility of functional NIRS, particularly in challenging subject groups ...

Comparative evaluation of hemodynamic responses and ease of intubation with airtraq video laryngoscope versus macintosh laryngoscope in patients with ischemic heart disease

Annals of Cardiac Anaesthesia, 2019
Introduction: Hemodynamic responses during laryngoscopy can potentially precipitate ischemia in patients with coronary artery disease. There are conflicting reports regarding the hemodynamic stress responses between the conventional Macintosh and video ...

A hierarchical model for simultaneous detection and estimation in multi-subject fMRI Studies [PDF]

NeuroImage 98, 2014, p. 61-72, 2014
In this paper we introduce a new hierarchical model for the simultaneous detection of brain activation and estimation of the shape of the hemodynamic response in multi-subject fMRI studies. The proposed approach circumvents a major stumbling block in standard multi-subject fMRI data analysis, in that it both allows the shape of the hemodynamic response

Comparing the effect of dexmedetomidine with magnesium sulfate on hemodynamic changes in patients undergoing laparoscopic cholecystectomy [PDF]

Fiyz̤, 2023
Background: Evolution of laparoscopic surgery has been enormous help to both patient and surgeon, although incidence of pneumoperitoneum as consequence of laparoscopic surgery would cause hemodynamic instability.

A hemodynamic decomposition model for detecting cognitive load using functional near-infrared spectroscopy [PDF]

arXiv, 2020
In the current paper, we introduce a parametric data-driven model for functional near-infrared spectroscopy that decomposes a signal into a series of independent, rescaled, time-shifted, hemodynamic basis functions. Each decomposed waveform retains relevant biological information about the expected hemodynamic behavior.
