There have been several studies on the kinetics of . oxygen uptake (VO2) responding to impulse work (Bakker et al., 1980; Hughson et al., 1988; Swanson, 1990; Whipp and Ward, 1991), and it has been demonstrated . that VO2 is composed of two components (phase I and phase II). With regard to these components, Hughson et al. (1988) have suggested that phase I reflects an immediate increase in pulm...

Blood and stripped hemoglobin from Nelore cattle individuals were submitted to oxygen equilibrium experiments in both gasometric and spectrophotometric methods. No difference was detected in oxygen affinity and Bohr effect among Hb A, Hb B and Hb AB in experiments with both blood and stripped hemoglobin, in the presence and absence of the chloride ion. However, n values (Hill plots) were higher...

Blood is a liquid tissue in which dissolved with abundant chemical factors and millions of different cells The reduction of unwanted side effects, especially diseases that emerge through blood such as HIV and hepatitis, has a significant role for modern medicine of transfusion and transplantation. The issues and costs of human blood collection and storage, direct this procedure towards the use ...

BACKGROUND A phenylalanine-free amino acid based protein substitute is necessary to provide the major source of protein in phenylketonuria (PKU). Protein substitutes in PKU are usually given as drinks. These are unpalatable and compliance is often poor. Tablets containing a suitable mixture of phenylalanine-free amino acids (Aminogran Food Supplement, UCB) are now available. AIMS To compare t...

blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. in this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...

Context Measurement of blood haemoglobin (Hb) concentration by pulse oximetry (SpHb) could be of value to determine when erythrocytes should be transfused during surgery, but the effect of infusion fluids on the results is unclear. Objective To study the effect of crystalloid and colloid fluid on the accuracy (bias) and precision of SpHb to indicate the venous Hb concentration in volunteers. De...
