Near-infrared spectra absorbance of blood from sickle cell patients and normal individuals

Absorption Spectra of Normal Adults and Patients with Sickle Cell Anaemia Haemoglobins Treated with Hydrogen Peroxide at Two pH Values

Background: The aim of the present study was application of haemoglobin absorption spectroscopy as a distinguishing tool for identification of two haemoglobin types-HbA and HbS. Material and Methods: Millimolar absorptivities of normal adult haemoglobin (HbA) and sickle cell haemoglobin (HbS) were monitored at pH values of 7.2 and 5.0, within the ultra violet and visible spectral range (250-...

background: the aim of the present study was application of haemoglobin absorption spectroscopy as a distinguishing tool for identification of two haemoglobin types-hba and hbs. material and methods: millimolar absorptivities of normal adult haemoglobin (hba) and sickle cell haemoglobin (hbs) were monitored at ph values of 7.2 and 5.0, within the ultra violet and visible spectral range (250-650...

Characteristics of Blood Samples From Normal Donors and Sickle Cell Anemia Patients

Recent findings that hemoglobin S gelation was greatly increased only between blood and sickling are pH-dependent and also pH 7.4 and 7.2 (cell pH 7.2 and 7.0. a shift influence oxygen affinity suggested that that strongly affects gelation). with L log the red cells containing this hemoglobin p50/ L pH -0.92 to -0.99 (normal variant might show an abnormal Bohr 0.42 to 0.46). Thus a drop in SS b...

Near-Infrared Spectra of Ultraluminous Infrared Galaxies.

Near-infrared spectra with a resolution of lambda&solm0;Deltalambda approximately 1100 in the rest-wavelength range of 1.8-2.2 µm have been obtained for a complete sample of 33 ultraluminous infrared galaxies (ULIRGs). Of the 33 objects observed, two show evidence of a central active galactic nucleus (AGN) through either a broad Paschen-alpha line or emission in the 1.963 µm fine structure of [...
