Certain types of bacteria accumulate on the papillae (the small bumps that cover the tongue) and create blood pigments
, which can make the tongue look black.
Expanded porphyrin is a term we introduced into the literature in 1988 to describe larger homologues of natural blood pigments
, such as the dyes (called heme) that make blood red.
At the same time metabolic rate is reduced at lower temperatures, with the consequence that in some species blood pigments may be less important (for hemocyanin, see Mauro and Mangum, 1982b; Burnett et al., 1988).
However, the capacity of their blood pigment, hemocyanin, for carrying oxygen is constrained by the low concentration of an extracellular pigment.
Low-molecular-weight organic substances that contribute to blood pigment function in vertebrates or crustaceans are not found in this group.
Comparison of hemocyanin oxygen binding in cephalopods of different metabolic rates and from various latitudes should show how hemocyanin oxygen transport has adapted to different temperature regimes at various levels of metabolic activity and how blood pigment function contributes to the oxygen limitation of thermal tolerance.
senoi hemocyanin but so high in the blood pigment of cold-adapted giant squid (cf.
The measurement of the blood pigments oxyhemoglobin, methemoglobin, and bilirubin in cerebrospinal fluid (CSF) has been useful in the differential diagnosis of various hemorrhaggc and traumatic disorders of the brain (1-9).
A solution to this problem was found in the mathematical step-by-step (iterative) unraveling of the main absorbance scan into the scans of the individual blood pigments via the iterative process.
Concentrations of the blood pigments were then calculated with a mathematical approximation technique (iteration procedure).
The linearity of the method was investigated by increasing the concentration of one of the blood pigments in a solution containing high concentrations (3 [micro]mol/L) of the other two pigments.
The cooling roll-on applicator refreshes the eye area delivering a mix of mineral pigments to cover your dark circles and Haloxyl to absorb coloured blood pigments
, firm and tone.
