1. Applying Different Sample Treatment Strategies for Evaluating Phosphorus Distribution in Orange Juice
Assessment of phosphorus in fruit juices is of great interest due to its essentiality and nutritional properties. This study applied sample treatment strategies to determine phosphorus in fractions of juices. Firstly, total phosphorus (Ptotal) was determined from digestion and sample suspension exploring direct analysis by inductively coupled plasma optical

2. VALIDAÇÃO DE MÉTODO POR MEFS-HS/CG-EM PARA DETERMINAÇÃO DE CARBARIL EM PLASMA SANGUÍNEO
The aim this research is to develop a HS-SPME/GC-MS method to analyze the carbaryl in blood plasma samples of the rural workers, who live round the perimeter of Chapada do Apodi-CE. This was achieved by chromatographic signal of the 1-naftol, degradation product of carbaryl with the intention of evaluating the degree of exposure of the workers to pesticides,

3. Low-temperature Plasma Assisted Thermochemical Treatments of AISI 420 Steel: Comparative Study of Obtained Layers
Formation of metastable C–, N–, or even Formation of metastable C–, N–, or even C/N– expanded phases can be observed for typical non-equilibrium conditions attained at the plasma assisted thermochemical treatments when temperatures relatively low are used. In present work, kinetics data are considered in a comparative study comprising low-temperatu

4. Topics in Present-day Science Technology and Innovation: Ultrafast Relaxation Processes in Semiconductors
The nowadays notable development of all the modern technology, fundamental for the progress and well being of world society, imposes a great deal of stress in the realm of basic Physics, more precisely on Thermo-Mechanical Statistics. In electronics and optoelectronics we face situations involving physical-chemical systems far-removed-from equilibrium, where

5. Interaction of lipophorin with Rhodnius prolixus oocytes: biochemical properties and the importance of blood feeding
Lipophorin (Lp) is the main haemolymphatic lipoprotein in insects and transports lipids between different organs. In adult females, lipophorin delivers lipids to growing oocytes. In this study, the interaction of this lipoprotein with the ovaries of Rhodnius prolixus was characterised using an oocyte membrane preparation and purified radiolabelled Lp (125I-L

6. Efeitos da Acupuntura, Eletroacupuntura e Metformina Sobre o Estresse Oxidativo, InflamaÃÃo e Glicemia em Ratas Sadias Submetidas a EstÃmulo EstrogÃnico / EFFECTS OF ACUPUNCTURE, ELETROACUPUNCTURE AND METFORMIN ON OXIDATIVE STRESS, INFLAMMATION AND BLOOD GLUCOSE IN HEALTHY RATS SUBMITTED TO ESTROGENIC STIMULATION
The physiological performance of cellular activity requires a balance between the production of free radicals and their deactivation by regulators and surge protectors. When this balance is broken, the oxidative stress takes place. Several experimental studies using estrogens to induction of ovarian and metabolic disorders, with emphasis on the polycystic ov

7. Desenvolvimento de métodos cromatográficos para análises de antimicrobianos em amostras complexas / Development of chromatographic methods for analysis of antimicrobials in complex samples
This work describes the development of chromatographic methods in combination with microextraction techniques for the determination of parabens in cosmetic and human milk samples and of rifampicin in plasma samples. The design of a molecularly imprinted extraction phase for the solid-phase extraction (SPE) analysis of parabens in human milk samples is also r

8. Associação entre haplótipos de metaloproteinase-9 de matriz extracelular (MMP-9) e obesidade infantil : efeitos sobre a concentração plasmática de MMP-9 / Association between haplotypes of matrix metalloproteinase-9 extracellular matrix (MMP-9) and childhood obesity : effects on plasma concentration of MMP-9
The childhood obesity is important risk factor for cardiovascular diseases, in particular, atherosclerose. This condition is characterized by the accumulation of lipids and fibrous elements in the large arteries in which inflammatory mechanisms and vascular remodeling are involved. In this context, matrix metalloproteinase 9 (MMP-9) - endopeptidade capable o

9. Measurement of the plasma boundary shift and approximation of the magnetic surfaces on the IR-T1 Tokamak
In this research we measured the plasma boundary shift using array of magnetic pick- up coils on the IR- T1 tokamak. Also we approximated the magnetic surfaces by an equilibrium calculation. Firstly, four magnetic probes were designed, constructed, and installed on outer surface of the IR- T1 tokamak chamber and then plasma boundary displacement measured fro

10. Effect of electron inertial delay on Debye sheath formation
Present contribution deals with the role of weak but finite electron inertia on the sheath formation condition. As reported earlier this becomes effective when the ions' drift velocity exceeds the phase velocity of the acoustic wave fluctuations. Such situation has natural existence near the sheath edge. Keeping this in mind we have revisited the problem of

11. Desenvolvimento das barras imunosorventes de agitação e avaliação das técnicas extração sortiva em barra de agitação, microextração em sorvente empacotado e cromatografia líquida para análise de antidepressivos em amostras de plasma / Development of immunosorbent stir bars and evaluation of stir bar sorptive extraction, microextraction by packed sorbent and liquid chromatography for the analysis of antidepressants in plasma samples
In this work, polyclonal and monoclonal anti-fluoxetine antibodies were developed in rabbits and mice by immunization with fluoxetine-bovine albumin conjugate, respectively. The developed antibodies were characterized on the basis of the specificity against the drug by ELISA (enzyme linked immunosorbent assay) and, subsequently they were purified by labmade

12. Apolipoprotein CIII polymorphism and triglyceride levels of a japanese population living in southern Brazil
Apolipoprotein CIII (apo-CIII) participates in the regulation of triglyceride-rich lipoprotein metabolism. Several polymorphic sites have been detected within and around the apo-CIII gene. Here, we examined the relationship between apo-CIII Sst I polymorphism (CC, CG, GG genotypes) and plasma triglyceride (TG) levels in a group of 159 Japanese individuals li
