Studies on Digitalis VI
T IS undisputed that the administration of digitalis to patients with many forms of congestive heart failure results in an improvement in both the clinical state and in the abnormal circulatory dynamics that are characteristic of heart failure.'-6 The effects of digitalis in subjects without heart failure are less well defined. Although some glycosides augment the contractile force of nonfailin...
متن کاملComparison Studies on Complexation of Molybdenum(VI) with Aspartic Acid And Glutamic Acid in Different Dielectric Constants1
Equilibria of the reaction of molybdenum(VI) with L-aspartic acid (Asp) and L- Glutamic acid(Glu) have been studied by spectrophotometric measurements in mixed solvent systems at an ionicstrength of 0.2 mol/dm3 sodium perchlorate, employed (15, 20, 25, 30± 0.1°C) at pH ranges of 3.2to 5.5 with a high ratio of ligand to metal. The stability constants of the complexes and theresulting free energy...
متن کاملMetal chelates of glycine and glycine peptides.
Since the advancement by Smith et al. (l-4) of the theory that metal ions are chelated simultaneously to enzyme protein and substrate in various polypeptidases, the nature of metal binding to peptides and proteins has become an important as well as an interesting problem. The chelate structures proposed by Smith (3), and later somewhat revised (5, 6), indicate that the metal is bound, at least ...
متن کاملAmino acid based metal-organic nanofibers.
Long chiral metal-organic nanofibers can be grown using conventional coordination chemistry and biologically derived components in a diffusion controlled growth procedure.
متن کاملFurther studies on the amino acid composition of seed globulins.
Wit,h the recent import,ant advances in methods of analysis of amino acids, our knowledge of the composition of many types of proteins is being rapidly extended. Microbiological procedures which have come to the fore in recent years provide relatively simple and rapid methods of assay, but strict controls are necessary in order to secure satisfactory results. Frequent checks with protein prepar...
