Descripción general

Hemoglobin (Hb) is the protein responsible for storage and transport of oxygen and other gaseous ligands in red blood cells (RBC). Hb is also the pioneer material for synthesis of Hb-based oxygen carriers (HBOCs) that can be used as substitutes for RBC. [1]

Aplicación

The solubility of α-elastin has been applied to construction of elastin-mimetic biomaterials.

Acciones bioquímicas o fisiológicas

Oxygen transporter, NO scavenger
Oxygen transporter. The Fe2+/Fe3+ balance is a physiological indicator of blood oxygenation; deoxygenated hemoglobin accessorizes a feedback loop by reducing nitrite to NO, a vasodilator which enhances blood flow to oxygen-deprived tissues.

Precaución

Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin.

Hemoglobin-based oxygen carriers (HBOC) are currently being developed as red blood cell (RBC) substitutes for use in transfusion medicine. Despite significant commercial development, late stage clinical results of polymerized hemoglobin (PolyHb) solutions hamper development. We synthesized two types of PolyHbs

The reduction of trial-to-trial variability (TTV) in task-evoked functional near-infrared spectroscopy signals by considering the correlated low-frequency spontaneous fluctuations that account for the resting-state functional connectivity in the brain is investigated. A resting-state session followed by a task-state session of

In conventional functional near-infrared spectroscopy (fNIRS), systemic physiological fluctuations evoked by a body's motion and psychophysiological changes often contaminate fNIRS signals. We propose a novel method for separating functional and systemic signals based on their hemodynamic differences. Considering their physiological
