This article reviews the basic principles of frequency-domain near-infrared spectroscopy (FD-
NIRS), which relies on intensity-modulated light sources and phase-sensitive optical …

Near-infrared spectroscopy (NIRS) is used to monitor regional cerebral oxygenation (rScO2)
during cardiac surgery but is less established during non-cardiac surgery. This systematic …

The level of tissue oxygenation provides information related to the balance between oxygen
delivery, oxygen utilization, tissue reactivity and morphology during physiological conditions …

Antecedentes: El cerebro es un órgano que tiene una amplia perfusión sanguínea. Muchos
factores como la hipoxia, la anestesia, el stress o la presencia de CO2, iones hidrogeno en …

Evidence points to heightened physiological arousal in response to acute stress exposure
as both a prospective indicator and a core characteristic of posttraumatic stress disorder …

Nerve agents (NAs) are potent organophosphorus (OP) compounds with applications in
chemical warfare. OP compounds act by inhibiting acetylcholinesterase (AChE). Soman (O …

Over the past several decades, near-infrared spectroscopy (NIRS) has become a popular
research and clinical tool for non-invasively measuring the oxygenation of biological tissues …

Stress response is regulated by two primary neuroendocrine systems—the
hypothalamuspituitary-adrenocortical (HPA) and sympathetic adrenomedullary (SAM) …

Previous studies showed that the cerebrovasodilation response to hypercapnia is
attenuated with aging. The purpose of this study was to determine if normal aging attenuates …
