The effect of the menstrual cycle on hemoglobin mass
The impact of the menstrual cycle on oxygen-carrying capacity remains equivocal. Previous studies reported either reductions or no significant changes in hemoglobin concentration during the follicular phase when compared to the luteal phase of the menstrual cycle. Changes in plasma volume …

Effects of Hyperoxia on Thermal Tolerance and Indicators of Hypoxic Stress in Antarctic Fishes That Differ in Expression of Oxygen-Binding Proteins
… Channichthyidae) are unique in lacking the oxygen carrier hemoglobin (Hb) in their blood, leaving them with only 10% of the oxygen-carrying capacity observed in closely related red-blooded fishes. Previous studies have shown that icefishes have lower critical thermal maxima …

Factors limiting the exercise tolerance of patients with end-stage renal failure undergoing maintenance haemodialysis
Exercise tolerance, measured as peak oxygen consumption (VO₂ peak), is very low in patients with end-stage renal failure undergoing maintenance haemodialysis. Due to their associated anaemia and low peak heart rates during maximal exercise it has been argued that the reduced blood oxygen carrying …

Influx and Efflux of Adenine Nucleotides From Erythrocytes Regulate Oxygen Transport and Systemic Metabolism
… responsible for ensuring a sufficient supply of oxygen to meet activity demands. The mammalian erythrocytes primarily modulate their oxygen-carrying capacity by varying the levels of organic phosphates, such as 2,3-BPG. In other organisms, such as fish, ATP instead of 2,3-BPG is used to modulate …

Different Methodologies to Characterize and Diagnose Sickle Cell Disease in Both Developed and Developing Nations
… protein hemoglobin. This disease causes reduced oxygen carrying capacity of RBC resulting in painful crisis, hemolytic anemia, and infection susceptibility. SCD affects around 100,000 individuals in USA alone and 14 million people globally. SCD affected individuals have high mortality rates. …

Rheological aspects of sickle cell anemia and related hemoglobinopathies
… of certain hemoglobinopathies with respect to oxygen tension, the concept of optimum hematocrit was employed. The optimum hematocrit is defined as the hematocrit at which the erythrocyte flow rate is the greatest. It therefore represents the optimum oxygen carrying capacity of blood. Using a …

Endothelin-1 and Hypoxic Vascular Remodeling in Ovine Fetal Cerebral Arteries
… hypoxia resulting from decreased maternal oxygen uptake, insufficient oxygen carrying capacity, or compromised oxygen delivery to the fetus jeopardizes fetal oxygen delivery, detrimentally affecting growth and development of the immature vasculature. Hypoxia transiently increases Hypoxia …

FROM CELL TO SYMBOL: A BIOCULTURAL STUDY OF ANEMIA AND SUBJECTIVITY AMONG THE POQOMCHI' MAYA IN GUATEMALA
… nearly 2 billion people worldwide by reducing oxygen carrying capacity in the blood. Practitioners of Western biomedicine consider anemia to be an easily treatable ‘symptom’ that results from some other disease, injury, or pregnancy. Conversely, in impoverished communities anemia has multiple …

Chemical Looping for Selective Oxidations
… of reactions (viz. abstraction or insertion of oxygen), this technology is based upon the use of oxygen carriers. These materials, typically metal oxides, reversibly store and release oxygen, and there is growing interest in using these materials for selective oxidations. This Dissertation …

Multispectral Imaging of Skin Oxygenation
… for quantitative measurement of skin tissue oxygen saturation (StO2). Oxygen saturation is the percentage of oxygen carried in the blood over the total oxygen carrying capacity of blood. Skin StO2 is an important indicator of skin tissue clinical status. Measurement of skin tissue oxygenation …

System and Reactor Design, and Materials Testing, for Efficient Thermochemical Solar Fuel Production in Temperature/Pressure Swing Redox Cycles
… oxides like doped ferrites or ceria in a low oxygen environment. The reduced metal oxide is then used to split water at ~ 800℃ and atmospheric pressure. The large temperature and pressure swings severely penalize heat-to-fuel conversion efficiency if measures like heat recovery and pressure …
