Background Anemia is associated with morbidity and mortality and frequently leads to transfusion of erythrocytes. The authors sought to directly compare the effect of high inspired oxygen fraction versus transfusion of erythrocytes on the anemia-induced increased heart rate (HR) in humans undergoing experimental acute isovolemic anemia. Methods The authors combined HR data from healthy subjects undergoing experimental isovolemic anemia in seven studies performed by the group.

Abstract:

Pesticides are chemicals used to control insects, fungi, weeds, and others. Unrestrained use of pesticides leads to poisoning that has an impact on inflammation and anemia. To provide evidence for this notion, acetylcholinesterase enzyme levels, blood sedimentation rates, and blood hemoglobin levels of farmers exposed to pesticides have been studied. The study design was quantitative in a cross-sectional manner. The participants of the study were all members of the Kurnia Makmur farmer group in Landasan Ulin Utara District, Banjarbaru with a total sample of 60 people. An examination of acetylc

Abstract:

The clam Solemya reidi, which survives in sulfide-rich sediments, houses intracellular sulfide-oxidizing bacteria as symbionts in its gills. The gill bacteriocytes also contain a high concentration of cytoplasmic hemoglobin. Although the in situ hemoglobin optical spectrum was not altered in the presence of hydrogen sulfide, hemoglobin deoxygenation was significantly slowed and incomplete when sulfide was present. A sulfide-mediated decrease in oxygen consumption rate, a shift in intracellular pH or the conversion of hemoglobin to an unusual derivative could all slow in situ hemoglobin deoxyge

Abstract. Chronic kidney disease (CKD) is characterized by a decrease in glomerular filtration rate (GFR) <60 ml/min/1.73 that occurs for more than 3 months. Glomerular filtration rate is one of the parameters commonly used to assess kidney function and can describe the degree of kidney damage. Further deterioration of kidney function can lead to serious complications, including decreased hemoglobin levels that manifest clinically in symptoms of anemia. Changes in hemoglobin levels are one of the indicators that can be used to assess the occurrence of these complications. This study aims to

Experimental measurements have suggested a consumption rate of nitric oxide (NO) by red blood cells (RBCs) that is orders of magnitude smaller than that of an equivalent concentration of free hemoglobin in solution. This difference has been attributed to external diffusion limitations in the transport of NO from the plasma to the surface of the RBC or to resistance in the transport through the erythrocytic membrane.

Abstract:

Abstract Alpha hemoglobin stabilizing protein (AHSP) is an abundant erythroid factor that specifically binds and stabilizes free α hemoglobin (Kihm et al., Nature 417:758, Gell et al., JBC, 277:40602). In mice, AHSP deficiency causes oxidative stress, mild anemia, and reticulocytosis. Furthermore, loss of AHSP exacerbates α globin precipitation and anemia in a murine model for β thalassemia. These data suggest that AHSP operates as a molecular chaperone to stabilize free α hemoglobin and inhibit its ability to catalyze redox chemistry. We investigated how AHSP associates with α hemoglobin and

Abstract:

Background Erythrocytes are transfused to improve oxygen delivery and prevent or treat inadequate oxygenation of tissues. Acute isovolemic anemia subtly slows human data processing and degrades memory, increases heart rate, and decreases self-assessed energy level. Erythrocyte transfusion is efficacious in reversing these effects of acute anemia. We tested the hypothesis that increasing arterial oxygen pressure (Pao2) to 350 mmHg or greater would supply sufficient oxygen to be equivalent to augmenting hemoglobin concentration by 2-3 g/dl and thus reverse the effects of acute anemia.

Abstract:

AbstractHemoglobin (Hb) constitutes a vital link between ambient O2 availability and aerobic metabolism by transporting oxygen (O2) from the respiratory surfaces of the lungs or gills to the O2‐consuming tissues. The amount of O2 available to tissues depends on the blood‐perfusion rate, as well as the arterio‐venous difference in blood O2 contents, which is determined by the respective loading and unloading O2 tensions and Hb‐O2‐affinity. Short‐term adjustments in tissue oxygen delivery in response to decreased O2 supply or increased O2 demand (under exercise, hypoxia at high altitude, cardiov

Background. In patients with diabetes mellitus, pathologic changes occur in multiple organs and systems, the pathogenesis of which involves inflammatory reactions. The chronic inflammatory process can lead to the development of anemia. Several changes in red blood cells have been found to affect the processes of hemoglobin glycation, making it difficult to diagnose carbohydrate metabolism disorders. The aim of the present study was to analyze the relationship between the level of glycated hemoglobin (HbA1c) and the concentration of hemoglobin and erythrocyte parameters. Materials and methods.
