1. Evaluating red meat putrefaction in long term storage in freezing condition based on co-variation of major biogenic amines and Total Volatile Nitrogen
Abstract Nearly all of the rejected frozen carcasses in Asian countries are due to their high amount of total volatile nitrogen (TVN). The main aim of this study was evaluating red meat putrefaction based on putrescine and cadaverine content in red meat as major biogenic amines that contributed in TVN content during long-term storage in freezing condition.

2. Simultaneous Quantification of Plasma Catecholamines and Metanephrines by LC-MS/MS
The quantification of the low levels of catecholamines and metanephrines in biological fluids is important for clinical screening of pheochromocytoma/paraganglioma and diagnosis of overtraining syndrome in athletes. We introduce a novel, accurate and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for simultaneous quantification of

3. EFFECT OF PRE-SLAUGHTER CONFINEMENT STRESS ON PHYSICOCHEMICAL PARAMETERS OF CHICKEN MEAT
Resumo Foi avaliado o efeito do estresse produzido pelo tempo de espera pré-abate sobre a produção de aminas biogênicas, pH e cor pelo sistema CIELab (onde três variáveis L*, a*, b* foram determinadas: L* indica a luminosidade, a* indica o vermelho e b* determina o amarelo) na carne de peito de frango. Antes do abate 25 frangos de carne foram seleciona

4. Bioactive compounds and juice quality from selected grape cultivars
ABSTRACT Grape juices have been valued due to their potential health benefits, which have demanded increased grape productivity and quality. Five grape cultivars grown in Brazil, Isabel Precoce, Carmem, Violeta, Concord and Bordo were evaluated in 2013 and 2014 seasons for bioactive components and also for juice processing quality traits. Production cycle wa

5. Technology and safety assessment for lactic acid bacteria isolated from traditional Bulgarian fermented meat product "lukanka"
Abstract The present work discusses the technological and new selection criteria that should be included for selecting lactic acid bacteria for production of fermented meat. Lactic acid bacteria isolated from Bulgarian traditional fermented "lulanka" salami was studied regarding some positive technological parameters (growth at different temperature, pH, and

6. Central Composite Design to Optimizate the Derivatization Procedure for Analysis of Biogenic Amines by HPLC-UV
A simple benzoylation procedure was optimized for the biogenic amines derivatization prior to high-performance liquid chromatography determination. The significant factors affecting biogenic amine benzoylation yield were optimized by central composite design (CCD). The obtained optimal conditions resulted in a chromatographic peaks area increase with fewer i

7. Bacteria isolated from Korean black raspberry vinegar with low biogenic amine production in wine
Abstract A high concentration of histamine, one of the biogenic amines (BAs) usually found in fermented foods, can cause undesirable physiological side effects in sensitive humans. The objective of this study is to isolate indigenous Acetobacter strains from naturally fermented Bokbunja vinegar in Korea with reduced histamine production during starter fermen

8. Biological characterization of compounds from Rhinella schneideri poison that act on the complement system
Background The skin secretions of toads of the family Bufonidae contain biogenic amines, alkaloids, steroids (bufotoxins), bufodienolides (bufogenin), peptides and proteins. The poison of Rhinella schneideri, formerly classified as Bufo paracnemis, presents components that act on different biological systems, including the complement system. The aim of this

9. The influences of fish infusion broth on the biogenic amines formation by lactic acid bacteria
The influences of fish infusion decarboxylase broth (IDB) on biogenic amines (BA) formation by lactic acid bacteria (LAB) were investigated. BA productions by single LAB strains were tested in five different fish (anchovy, mackerel, white shark, sardine and gilthead seabream) IDB. The result of the study showed that significant differences in ammonia (AMN) a

11. Perfil antipsicótico de alstonina : ação em modelos de sintomas negativos, alterações em aminas biogênicas e efeitos adversos em camundongos / Antipsychotic profile of alstonine : action in animal models of negative symptoms, alterations in biogenic amines and side effects in mice.
A esquizofrenia é um transtorno psiquiátrico grave, caracterizado por distúrbios do pensamento, prejuízo da lógica, alterações cognitivas e emocionais, e/ou isolamento social. Apesar da introdução de novos antipsicóticos, um grupo considerável de pacientes ainda é refratário aos tratamentos disponíveis. Além disso, a alta incidência de efeito
