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 کاملSpectroscopic Studies of R(+)-α-Lipoic Acid—Cyclodextrin Complexes
α-Lipoic acid (ALA) has a chiral center at the C6 position, and exists as two enantiomers, R(+)-ALA (RALA) and S(-)-ALA (SALA). RALA is naturally occurring, and is a cofactor for mitochondrial enzymes, therefore playing a major role in energy metabolism. However, RALA cannot be used for pharmaceuticals or nutraceuticals because it readily polymerizes via a 1,2-dithiolane ring-opening when expos...
متن کاملAlpha-Lipoic Acid
OBJECTIVE: To evaluate the efficacy and safety of oral treatment with the antioxidant alpha-lipoic acid (ALA) in NIDDM patients with cardiac autonomic neuropathy (CAN), assessed by heart rate variability (HRV). RESEARCH DESIGN AND METHODS: In a randomized, double-blind placebo-controlled multicenter trial (Deutsche Kardiale Autonome Neuropathie [DEKAN] Study), NIDDM patients with reduced HRV we...
متن کاملAlpha Lipoic Acid
Alpha lipoic acid, or just lipoic acid (LA), is a unique and potent antioxidant. It can deliver antioxidant activity in both fatand water-soluble mediums, and it is capable of having an antioxidant effect in both its oxidized (LA) and reduced (DHLA [dihydrolipoic acid]) forms (Goraca et al., 2011). This effectively allows LA to deliver its antioxidant effect to any cell or tissue type, as well ...
