1. Development and application of a test mixture for untargeted liquid chromatography-mass spectrometry analysis of urine samples
Metabolic profiling of complex biological matrices based on liquid chromatography-mass spectrometry (LC-MS) allows detecting a wide range of metabolites with distinct concentrations and physicochemical properties. Given the complexity of samples and the necessity of a comprehensive approach in untargeted metabolomics, quality control strategies are mandatory

2. Evaluation of the Metabolic Profile of Arabica Coffee via NMR in Relation to the Time and Temperature of the Roasting Procedure
Coffee is one of the most popular and consumed products in the world, with high nutritional value and economic importance. However, some factors can change the organoleptic properties of a coffee species, without causing significant damage such as loss of important components. The present study evaluated the chemical profile, via nuclear magnetic resonance (

3. Estudo da atividade metanogênica específica de diferentes lodos anaeróbios
RESUMO O estudo da atividade metanogênica específica (AME) constitui uma importante ferramenta para o controle operacional de reatores anaeróbios, pois apresenta parâmetros de monitoramento da eficiência e estabilidade de um reator biológico. Nesse sentido, o presente trabalho visou determinar a AME de lodos provenientes de reatores anaeróbios de flux

7. Detection of Plasmodium in faeces of the New World primate Alouatta clamitans
Abstract Plasmodium falciparum and Plasmodium vivax have evolved with host switches between non-human primates (NHPs) and humans. Studies on the infection dynamics of Plasmodium species in NHPs will improve our understanding of the evolution of these parasites; however, such studies are hampered by the difficulty of handling animals in the field. The aim of

8. FTIR Spectroscopy Revealing the Effects of Laser and Ionizing Radiation on Biological Hard Tissues
This work evaluated the influence of ionizing and non-ionizing irradiations on the chemical structure of hard tissues using the mid-infrared spectroscopy. Enamel, dentin and bone slabs were submitted to gamma irradiation, as well as to Nd:YAG (λ = 1064 nm) and Er,Cr:YSGG (λ = 2078 nm) laser irradiations. The composition of slabs were evaluated by the Fouri

9. Hematological differences between patients with different subtypes of sickle cell disease on hydroxyurea treatment
OBJECTIVE: Sickle cell anemia and the interaction S/Beta thalassemia differ in hematological values due to microcytosis and hypochromia caused by the thalassemic mutation. The clinical benefit of long-term hydroxyurea treatment is undeniable in sickle cell disease with monitoring of the biological action of the drug being by the complete blood count. The obj

10. Determinação de elementos químicos inorgânicos em amostras de sangue total humano e de animais de experimentação (hamster dourado e cavalo da raça crioula) pela técnica de fluorescência de raios X(EDXRF) / Inorganic elements determination in human and animal whole blood samples by X-ray fluorescence technique (EDXRF)
Blood is a suspension of cells contained in a complex liquid called plasma. The term whole blood refers to samples with both solid and liquid parts. Inorganic elements are responsible for essential functions, such as osmotic regulation, cardiac frequency and contractibility, blood clotting and neuromuscular excitability. The determination of inorganic elemen

11. Current status of PET/CT in the diagnosis and follow up of lymphomas
Lymphomas are a heterogeneous group of malignancies that have a distinct biological behavior according to the subtype and degree of differentiation. Adequate staging, which has a direct impact on prognosis, is essential to properly plan therapy. Structural cross-sectional imaging, such as computed tomography, has been the standard imaging tool to stage and m

12. Toxic effects of cadmium on the microalgae Lingulodinium polyedrum using high performance liquid chromatography coupled to mass spectrometry (LC-MS/MS) / Análise dos efeitos tóxicos de cádmio sobre a microalga Lingulodinium polyedrum utilizando cromatografia líquida de alta eficiência acoplada à espectrometria de massas (LC-MS/MS)
Given the increase of environmentally harmful human activities, in particular the ones injurious to the aquatic environment, it is important to elucidate the defense mechanisms utilized by organisms exposed to damaging agents. Those species can later be suggested to be used as pollution bioindicators or bioremediatiors. Algae are of particular importance bec
