In this study, the influence of fullerene junction on the chemical features of 16 different drugs including Captopril, Clonidine, Methyldopa, Naphazoline, Oxymetazoline, Tetrahydrozoline, Xylometazoline, Tolazoline, Clemastine, Procyclidine, Tyramine, Nicotine, Dextroamphetamine, Fluoxetine, Metoprolol and Enalapril was investigated computationally. For this purpose, the mentioned drugs were pl...

Session Information for Program Number 14 Print Close window Abstract Content Program Nr: Tyramine Modulates Foraging Behavior and Head Movements. , Melissa Hunter-Ensor, Niels Ringstad, Bob Horvitz. HHMI, Dept. Biology, MIT, Cambridge, MA 02139, USA. Tyramine and octopamine are biogenic amines implicated in several invertebrate behaviors. Tyramine biosynthesis requires the decarboxylation of t...

BACKGROUND Cardiac transplantation (CT) causes total cardiac denervation. METHODS AND RESULTS To test directly for sympathetic reinnervation in humans, we measured the cardiac release of norepinephrine (NE) in response to tyramine (an agent that causes NE release from intact sympathetic nerve terminals) and sustained handgrip exercise (a reflex sympathetic stimulus) in 12 patients less than 5...

wall carbohydrates, and organic acids. The hydroxycinnamic acid amides with tyramine and octopamine are also common types of conjugates.2) The formation of the amides serves a defensive purpose in solanaceous plants such as potato,3・4) tobacco5) and tomato.6) Various forms of stress, including physical injury, infection with pathogens and elicitor-treatments, induce the accumulation of hydroxyc...

Contractile responses of vascular smooth muscle strips (rabbit aorta) to angiotensin, vasopressin and serotonin are potentiated by amounts of metanephrine, ephedrine or tyramine that produce no contractions by themselves. Epinephrine and norepinephrine contractions of aortic strips are not potentiated. Phentolamine and bretylium prevent this potentiating effect of metanephrine and ephedrine; th...

The current study was aimed at investigating the effect of Areca catechu nut dichloromethane fraction (7 mg/kg) on monoamines (serotonin and dopamine) modulation (5-hydroxytryptophan-induced tremors and phenylethylamine-induced stereotypes) and its interaction with tyramine (cheese effect). The dichloromethane fraction caused pronounced increase in 5-HTP-induced tremors (50%) with negligible PE...

Bioactive-directed fractionation of n-butanol extract from fresh fruits of Randia siamensis led to isolate of 4 new pseudoginsenoside compounds: pseudoginsenosides-RT2, -RT3, RT4 and -RT5, together with 7 known compounds: tyramine, pseudoginsenosides-RT1 methyl ester, pseudoginsenosides-RT1, pseudoginsenoside-RP1, kaempferol-3-O-β-D-xylose(1-2)-βgalactose, kaempferol-3-O-β-D-galactose, and 5-O...
