Differential prooxidative effect of adult and fetal hemoglobin
(1986)
Human fetal hemoglobin assayed in a peroxidizing system shows an increased prooxidative effect when compared to human adult hemoglobin. This effect is related only to the oxyhemoglobin form since both fetal and adult ...
Crystallization and X-ray diffraction data analysis of oxyhemoglobin-I from the catfish Liposarcus anisitsi (pisces)
(1997-12-01)
Hemoglobin remains, despite the enormous amount of research involving this molecule, as a prototype for allosteric models and new conformations. Functional studies carried out on Hemoglobin-I from the South-American Catfish ...

Analysis of the expression and activity of nitric oxide synthase from marine photosynthetic microorganisms
(Springer, 2016-04)
Nitric oxide (NO) functions as a signaling molecule in many biological processes in species belonging to all kingdoms of life. In animal cells, NO is synthesized primarily by NO synthase (NOS), an enzyme that catalyze the ...
Prevalence and severity of sleep apnea in a group of morbidly obese patients
(2007)
Background: Obesity is the most important risk factor for obstructive sleep apnea. It is estimated that 70% of sleep apnea patients are obese. In the morbidly obese, the prevalence may reach 80% in men and 50% in women. ...

Healy, Katherine, Alain B. Labrique, J. Jaime Miranda, Robert H. Gilman, David Danz, Victor G. Davila-Roman, Luis Huicho, Fabiola Leon-Velarde, and William Checkley. Dark adaptation at high altitude: an unexpected pupillary ...
Effects of sildenafil on autonomic nervous function during sleep in obstructive sleep apnea
(Faculdade de Medicina / USP, 2010-01-01)
OBJECTIVE: To evaluate the effects of sildenafil on the autonomic nervous system in patients with severe obstructive sleep apnea. METHODS: Thirteen male patients with severe obstructive sleep apnea (mean age 43±10 years ...
The water effect on allosteric regulation of hemoglobin probed in water glucose and water glycine solutions
(Amer Soc Biochemistry Molecular Biology Inc, 2014)
