It is constantly in motion as the heart pumps blood through arteries to the different organs and cells of the body. The blood is returned back to the heart by the veins.

Blood consists of: · red blood cells containing hemoglobin that

A simple‚ rapid‚ specific and highly sensitive spectrofluorimetric method has been developed for the quantification of dabigatran etexilate mesylate (DAB) in bulk and capsule dosage form. A linear relationship was found between fluorescence intensity and DAB concentration in the range of 0.01-1.0 μg/ml in DMSO as solvent at an emission wavelength of 391 nm after excitation at 334 nm‚ with a good correlation coefficient (0.989). The detection and quantification limits were found to be 0.005 and 0
