BACKGROUND AND PURPOSE Sickle cell anemia is associated with compromised oxygen-carrying capability of hemoglobin and a high incidence of overt and silent stroke. However, in children with no evidence of cerebral infarction, there are changes in brain morphometry relative to healthy controls, which may be related to chronic anemia and oxygen desaturation. METHODS A whole-brain tract-based spa...

The effects of electromagnetic fields (EMFs) radiation at the frequency of 940 MHz on the structure and function of human adult and fetal hemoglobin (HbA and HbF) were studied. After extraction and purification of HbA and HbF, the oxygen absorption values for exposed and unexposed HbA and HbF to EMF were compared. The slope of oxygen absorption curve for exposed HbA was increased while that for...

A nitroxide spin-label probe was attached directly to a propionic acid group of heme in either the a or the P chain of hemoglobin. The electron paramagnetic resonance (EPR) spectrum of the spin label is altered by the spin-state change of the heme iron to which the spin label is attached. These hybrid hemoglobins showed normal optical and functional properties, indicating that the attachment of...

Critical ill patients experience acute physiological changes because the body cannot fulfill the oxygen demand to perform normal aerobic metabolism. Factors determining oxygen delivery include cardiac output, hemoglobin, and oxygen saturation. Incapability to fulfill adequate oxygen of the body to produce adenosine triphosphate (ATP) may occur due to decreased oxygen delivery and/or increased o...

Chronic obstructive pulmonary disease (COPD) is a syndrome with progressive and irreversible airflow limitation. The aim of this study was to evaluate the effect of Atorvastatins on blood parameters including blood gasses in patients with COPD. This randomized double-blind, controlled clinical trial study was conducted on  the case and control groups of patients with COPD in Vali-e-asr hos...
