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. Biogenic, sedimentary, and metamorphic limestone: a comparative characterization of soil amendment
RESUMO A correção da acidez é fundamental para a atividade agrícola em solos ácidos, assim como a caracterização e estudo do efeito no solo de fontes alternativas de corretivos. Objetivou-se caracterizar os calcários de origem biológica, sedimentar e metamórfica. Os calcários estudados foram: biogênico (CB), sedimentar (CS), comercial (CC) e o m�

5. 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

6. Composição elementar do aerossol atmosférico na região central da Bacia Amazônica
The processes and sources that regulate the elemental composition of aerosol particles were investigated in both fine and coarse modes during the dry and wet seasons. One hundred and nine samples were collected from the biological reserve Cuieiras - Manaus from February to October 2008, and analyzed together with 668 samples that were previously collected at

7. Inhalable particulate matter characterization in a medium-sized urban region in Brazil (São José dos Campos Town) - Part I: Morphology
In this study, the concentration and morphological characteristics of inhalable particulate material (PM10) were evaluated and associated with climatic conditions. The mean annual concentration was 11.0 µg m−3, varying between 0,647 µg m−3 and 36.8 µg m−3. Wind speed has a higher influence on PM10 dispersion, but direction was associated with partic

8. Estabilidade da sílica biogênica extraída de capim Jaraguá (Hyparrhenia rufa) em solução de NaOH
Biogenic silica is used to describe compounds of hydrated silica (SiO2.nH2O), with specific shapes and sizes, deposited in plants. The chemical composition of biogenic silica and its stability in Jaraguá grass was studied in increasing concentration of NaOH. The analytical results demonstrated high concentration of Si, Al, Fe, Mg, P and low of Cu, Cd and Zn

9. Uma peculiar tafocenose controlada por ação biogênica no triássico médio do Rio Grande do Sul, Brasil
We present here an outcrop with a peculiar fossil assemblage, including a distinct taphocoenosis in comparison to other fossiliferous outcrops of the Santa Maria Formation (Triassic, Paraná Basin). Fossil concentration in this outcrop is made-up of herbivorous non-mammalian cynodonts (Synapsida, Therapsida) only, tentatively assigned to Massetognathus. The

10. Biogenic fossil concentration in fluvial settings: an example of a cynodont taphocoenosis from the middle triassic of southern Brazil
Perto da cidade de Santa Cruz do Sul (região central do Rio Grande do Sul, Brasil), um afloramento Triássico da Formação Santa Maria apresenta uma assembléia fóssil bastante incomum, consistindo de uma concentração de restos esqueletais de terápsidos desarticulados, com predomínio de ossos de cinodontes herbívoros e carnívoros. Apenas um espécim

11. DETERMINAÇÃO DE MARCADORES ORGÂNICOS NO PERFIL SEDIMENTAR DO COMPLEXO ESTUARINO DE PARANAGUÁ (PR) POR CG-EM
The input evaluation of the organic matter in aquatic environment by anthropic activity can be done by the identification and quantification of molecular markers. Many studies point the application of the molecular markers for this objective but few of them evaluate the variation of the compound concentration through a long period of time registered on the s

12. Concentrações biogênicas em sistemas fluviais, fácies de planície de inundação : Sítio Linha Várzea, um estudo de caso para o triássico sul-brasileiro
O Sítio Linha Várzea, localizado a cerca de 4 km a nordeste da cidade de Paraíso do Sul – RS é composto por três afloramentos principais, situados às margens de três açudes artificiais de captação de água, o LV1/Base, o LV1/Topo, ambos subdivididos em Margem Leste e Oeste, e o LV2. Estes afloramentos são formados por siltitos avermelhados, cara
