Effect of organic phosphates on the sulfhydryl reactivities of oxyhemoglobins A and S. [PDF]

open access: yesJournal of Biological Chemistry, 1980
The /393 sulfhydryl groups of oxyhemoglobins A and S display a difference in reactivity with 5,5’-dithiobis- 2-nitrobenzoic acid. It is concluded that this difference arises from differences in tertiary structure in the vicinity of the p”“ site ...

rTMS Therapy Reduces Hypofrontality in Patients With Depression as Measured by fNIRS

open access: yesFrontiers in Psychiatry, 2022
Multichannel functional near-infrared spectroscopy (fNIRS) is a tool used to capture changes in cerebral blood flow. A consistent result for depression is a decrease in blood flow in the frontal cortex leading to hypofrontality, which indicates ...

Magnetic properties of oxyhemoglobin. [PDF]

open access: yesProceedings 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.

Formation of meso, N-diphenylprotoporphyrin IX by an aerobic reaction of phenylhydrazine with oxyhemoglobins. [PDF]

open access: yes, 2003
Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis.

Variation of quadrupole splitting in modified oxyhemoglobin: A Mössbauer effect study [PDF]

open access: yes, 2000
Human adult hemoglobin modified by both pyridoxal-5′-phosphate and glutaraldehyde in the oxy-form was studied by Mössbauer spectroscopy. Mössbauer spectra were measured at 87 and 295 K (hemoglobin in lyophilized form) and at 87 K (hemoglobin in frozen ...
