noradrenaline/potato

This study was undertaken to investigate some cardiovascular effects of Hypoxis hemerocallidea Fisch & CA Mey (Hypoxidaceae) corm (African potato) aqueous extract in experimental animal paradigms. The effect of the corm aqueous extract (APE) on myocardial contractile performance was evaluated on

o-Diphenoloxidase from potato tubers is inactivated in the course of the oxidation reaction of o-diphenols at the level of the enzyme-substrate complex. At 25 degrees C of the reaction mixture the enzyme inactivation rate constants (Kin) in oxidation of 10 mM solutions of the substrates were: for

Antioxidants are added to foods and drugs to inhibit their oxidation. As these additives are somewhat toxic, it is necessary to control the amount added to any food or drug. Liquid chromatography (LC) is a powerful tool for this purpose. Many antioxidants are electroactive molecules which enables

The Avr9 peptide elicitor from the fungus Cladosporium fulvum, the bacterial pathogen Pseudomonas syringae pathovar tomato carrying the avirulence gene avrPto (Pst (avrPto)), and the organophosphorous insecticide fenitrothion induce resistance-related responses in tomato lines carrying the Cf-9,

The mammalian pineal hormone melatonin (N-acetyl-5-methoxytryptamine), an aminoindole produced by the metabolism of serotonin (5-hydroxytryptamine), has been shown to be a potent scavenger for the highly toxic hydroxyl radical. Three substances that are very important in animal physiology (e.g., in
