The southern cattle tick (Rhipicephalus (Boophilus) microplus) is a hematophagous external parasite that vectors the causative agents of bovine babesiosis or cattle tick fever, Babesia bovis and B. bigemina, and anaplasmosis, Anaplasma marginale. The southern cattle tick is a threat to the livestock industry in many locations throughout the world. Control methods include the use of chemical aca...

Interstitial cystitis/painful bladder syndrome (IC) is a chronic syndrome of unknown etiology that presents with bladder pain, urinary frequency, and urgency. The lack of specific biomarkers and a poor understanding of underlying molecular mechanisms present challenges for disease diagnosis and therapy. The goals of this study were to identify noninvasive biomarker candidates for IC from urine ...

The responses of the blood vessels of the hand to intra-arterial infusion of tyramine and to application of ice to the forehead were examined in patients with Raynaud's phenomenon and in normal subjects. The vasoconstrictor responses to tyramine and to ice were not significantly different in the patients and control subjects. Following intra-arterial administration of reserpine the vasoconstric...

A biotin-tyramine conjugate (1) was found to covalently cross-link with peroxidase antibody 7G12 upon the catalytic oxidation of the tyramine moiety in the presence of hydrogen peroxide (H2O2). On the basis of this observation, a novel strategy was developed to select mutants of 7G12 Fab with enhanced peroxidase activity from a library of phage displayed antibodies. In such a selection, tyramin...

Barley offers several advantages as a model system for studies of the role of alkaloids in plant metabolism. Two distinct classes of alkaloids are synthesized by analogous yet separate mechanisms: N-methylated tyramine (1) and N-methylated indole derivatives (2). Because these alkaloids are made by young plants rather than by mature or flowering plants, large quantities of plant material can be...

The administration of antlpsychotlc drugs to the mouse caused a reduction in stnatal p-tyramme but did not change or increase m-tyramlne, these effects were observed for drugs such as chlorpromazlne, thioproperazlne, fluphenazine, halopendol, splperone, mohndone at low doses, ~-flupenthlxol and (+)-butaclamol (Juono, 1977a, 1979a, 1980a, Boulton & Juorlo, 1979) In contrast, the administration o...

Biogenic amines (BA) are nitrogenous compounds that possess biological activity. The source of production is the microbial decarboxylation of amino acids. This compounds are found in various types of cheese. The aim of this work was to evaluate the BA content of some traditional cheeses in West Azerbaijan province Iran. For this purpose, 70 samples of Koopeh, 10 samples of Lighvan and 5 samples...
