Magnetic properties of oxyhemoglobin. [PDF]
Proceedings of the National Academy of Sciences, 1977 When the magnetic susceptibility of frozen aqueous solutions of human oxyhemoglobin was measured in the range between 25 and 250 K, it showed a temperature-dependent behavior typical of a thermal equilibrium between a ground singlet state and an excited triplet state for two electrons per heme, the energy separation being [2J] = 146 cm-1.

Transnitrosation Signals Oxyhemoglobin Desaturation [PDF]
Circulation Research, 2008 See related article, pages 545–553 Erythrocytes dilate peripheral blood vessels as a function of oxyhemoglobin desaturation.1 This effect increases regional blood flow to hypoxic tissues. The mechanisms underlying the peripheral vasodilatory effects of desaturating erythrocytes are incompletely understood but do not involve activation of local ...

The oxyhemoglobin reaction of nitric oxide [PDF]
Proceedings of the National Academy of Sciences, 1999 The oxidation of nitric oxide (NO) to nitrate by oxyhemoglobin is a fundamental reaction that shapes our understanding of NO biology. This reaction is considered to be the major pathway for NO elimination from the body; it is the basis for a prevalent NO assay; it is a critical feature in the modeling of NO diffusion in the ...

Nitroxyl Accelerates the Oxidation of Oxyhemoglobin by Nitrite [PDF]
Free Radical Biology and Medicine, 2011 Angeli's salt (Na₂N₂O₃) decomposes into nitroxyl (HNO) and nitrite (NO₂(-)), compounds of physiological and therapeutic interest for their impact on biological signaling both through nitric oxide and nitric oxide independent pathways. Both nitrite and HNO oxidize oxygenated hemoglobin to methemoglobin.

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) and obstructive sleep apnea (OSA) are comorbid conditions that synergistically increase cardiovascular risk through systemic inflammation and insulin resistance. While continuous positive airway pressure (CPAP) is the standard treatment for OSA, its efficacy in improving hepatic ...

Awake Blue Light vs. KTP Laser Treatment for Vocal Fold Lesions: A Randomized Controlled Trial
The Laryngoscope, EarlyView.In this pilot randomized controlled clinical trial, the BL laser demonstrated clinical efficacy comparable to the KTP laser for office‐based treatment of benign vocal fold lesions. Both laser modalities were associated with significant improvements in patient‐perceived voice handicap, minimal post‐procedural pain, and favorable stroboscopic outcomes ...

Laser &Photonics Reviews, EarlyView.Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Lasers in Surgery and Medicine, EarlyView.ABSTRACT Objectives Paronychia is a common and often painful cutaneous adverse event of epidermal growth factor receptor inhibitor therapy that can impair function and quality of life. We report the first known case of amivantamab‐associated paronychia successfully treated with 532‐nm potassium‐titanyl‐phosphate laser.
