Tyramine degradation and tyramine/histamine production by lactic acid bacteria and Kocuria strains [PDF]

open access: yes, 2001
Of 53 strains of lactic acid bacteria and Kocuria, screened for production or degradation of biogenic amines, 29 Kocuria varians and four strains of Enterococcus faecalis produced tyramine and, at lower concentrations, histamine.

THE CHEMICAL ESTIMATION OF TYROSINE AND TYRAMINE

open access: yesJournal of Biological Chemistry, 1952
SUMMARY 1. 1-Nitroso-2-naphthol reacts with both tyrosine and tyramine to form a red-colored product which gradually changes to a stable yellow chromo- phore. 2. The yellow compound obtained by treating tyramine with nitroso- naphthol has been isolated. Analysis indicates it to be the product of combination of 1 mole equivalent of each with the loss of

Radiotherapy Enhances the Oncolytic Efficacy of the Novel Oncolytic Herpesvirus VG161 and Amplifies Its Antitumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
RT promotes VG161 replication in BC and its immunostimulatory transgenes expression, which is mediated by the upregulation of GADD34 and HVEM caused by RT. The combination therapy with VG161 and RT increases the abundances of tumor‐infiltrating lymphocytes and elicits potent systemic antitumor immunity, thereby effectively inhibiting local tumors and ...

Effect of hemorrhagic shock on release of norepinephrine by tyramine [PDF]

open access: yes, 1964
This study was undertaken to determine if the sympathetic discharge which accompanies hemorrhagic shock modifies the response to tyramine. In eight dogs the dose of tyramine equipressor to 1.0 µg/kg min of norepinephrine was 85 ± 8 µg/kg min in the ...
