1. Mineral content, phenolic compounds and bioactive amines of cheese bread enriched with cowpea
ABSTRACT Cheese bread presents great acceptance and market expansion. Due to the lack of standardization in its manufacturing, various ingredients can be added. It was aimed to determine the content of minerals, bioactive compounds and antioxidant activity in cheese bread enriched with biofortified cowpea. Two formulations were prepared, standard cheese brea

2. Metais traço e aminas bioativas em alface proveniente da agricultura urbana
Urban agriculture is an activity being practiced in every city of the world. Its practice has provided several benefits to growers, among them, availability of fresh vegetables, source of vitamins, minerals and bioactive compounds such as polyamines, which have shown antioxidant activity. However, urban agriculture can be a risk in case the vegetables are co

3. Retinal protective effects of topically administered agmatine on ischemic ocular injury caused by transient occlusion of the ophthalmic artery
Agmatine, an endogenous polyamine and putative neuromodulator, is known to have neuroprotective effects on various neurons in the central nervous system. We determined whether or not topically administered agmatine could reduce ischemic retinal injury. Transient ocular ischemia was achieved by intraluminal occlusion of the middle cerebral artery of ddY mice

5. Protective mechanism of agmatine pretreatment on RGC-5 cells injured by oxidative stress
Agmatine has neuroprotective effects on retinal ganglion cells (RGCs) as well as cortical and spinal neurons. It protects RGCs from oxidative stress even when it is not present at the time of injury. As agmatine has high affinity for various cellular receptors, we assessed protective mechanisms of agmatine using transformed RGCs (RGC-5 cell line). Differenti

7. Caracterização de pacientes e de dietas enterais artesanais de centros de alta complexidade em oncologia quanto aos teores de poliaminas
CARACTERIZATION OF PATIENTS AND OF ENTERAL HOMEMADE DIETS FROM CENTERS OF HIGH COMPLEXITY IN ONCOLOGY WITH RESPECT TO POLYAMINES. The five Centers of High Complexity in Oncology (CACON) from Belo Horizonte, MG were included in this study. Questionnaires were filled out by the person in charge regarding the homemade enteral diets prescribed to patients under

8. MECANISMOS ENVOLVIDOS NA ANTINOCICEPÇÃO CAUSADA PELA AGMATINA EM CAMUNDONGOS / MECHANISMS INVOLVED IN THE ANTINOCICEPTION CAUSED BY AGMATINE IN MICE
A agmatina é uma poliamina endógena, formada pela descarboxilação da L-arginina. Recentemente foi verificado que a agmatina é um importante neurotransmissor em mamíferos, estando relacionada com mecanismos de neuroproteção pós-injúria, ansiedade, epilepsia, depressão e com mecanismos antinociceptivos. O presente estudo avaliou os efeitos antinocic

9. Biogenic amines, volatile amines, free tryptophan and urea as chemical indices for quality and freshness evaluation of fish and sellfish. / Aminas biogenicas, aminas volateis, triptofano livre e ureia como indices quimicos de qualidade e frescor do pescado.
Fish and shellfish muscle is highly susceptible to spoilage during storage. Because quality quickly decreases during storage reliable chemical indices for quality and freshness evaluation are greatly needed. Total volatile bases-nitrogen (TVB-N), trimethylamine (TMA), biogenic amines, nucleotides, urea and free tryptophan have been suggested as freshness ind

10. Effects of central imidazolinergic and alpha2-adrenergic activation on water intake
Non-adrenergic ligands that bind to imidazoline receptors (I-R), a selective ligand that binds to alpha2-adrenoceptors (alpha2-AR) and mixed ligands that bind to both receptors were tested for their action on water intake behavior of 24-h water-deprived rats. All drugs were injected into the third cerebral ventricle. Except for agmatine (80 nmol), mixed liga

11. Transport of diamines by Enterococcus faecalis is mediated by an agmatine-putrescine antiporter.
Enterococcus faecalis ATCC 11700 is able to use arginine and the diamine agmatine as a sole energy source. Via the highly homologous deiminase pathways, arginine and agmatine are converted into CO2, NH3, and the end products ornithine and putrescine, respectively. In the arginine deiminase pathway, uptake of arginine and excretion of ornithine are mediated b

12. Enzymes of agmatine degradation and the control of their synthesis in Streptococcus faecalis.
Streptococcus faecalis ATCC 11700 uses agmatine as its sole energy source for growth. Agmatine deiminase and putrescine carbamoyltransferase are coinduced by growth on agmatine. Glucose and arginine were found to exert catabolite repression on the agmatine deiminase pathway. Four mutants unable to utilize agmatine as an energy source, isolated from the wild-
