13. In vitro degradation dynamics of neutral detergent fiber of signal grass according to supplementation with different sources of nitrogenous compounds and carbohydrates / Dinâmica de degradação in vitro da fibra em detergente neutro de capim-braquiária em função de suplementação com diferentes fontes de compostos nitrogenados e carboidratos
Two experiments were carried out to evaluate the utilization of fibrous carbohydrates from high quality grass by ruminal microorganisms. In the first experiment, it was studied the degradation dynamics of neutral detergent fiber (NDF) from high quality signal grass (Brachiaria decumbens Stapf.) according to supplementation with different sources of carbohydr

14. Degradation of the Herbicida Atrazina saw Processes Advanced of Oxidation / DegradaÃÃo do Herbicida Atrazina via Processos AvanÃados de OxidaÃÃo
Herbicide contamination of the aquatic environment is widespread, particularly that caused by the triazine group herbicide Atrazine, which is used for weed-control in sugar-cane crops in the State of Pernambuco in Brazil. Atrazine is a âpriority pollutantâ since it is carcinogenic and is highly resistant to biological breakdown, with a 12 months half-life

15. Perturbing non-linear systems, an approach to the control of chaos. / Perturbando Sistemas Não-Lineares, uma Abordagem do Controle de Caos
Inicialmente, consideramos o mapa Logístico com os vários fenômenos nele presentes, para depois, ao perturbarmos esse mapa, adicionando periodicamente um termo de amplitude constante, identificarmos os novos fenômenos e as alterações que a introdução da perturbação faz aparecer. Apresentamos o circuito eletrônico de Matsumoto e, em seguida, o cons

16. P-Glycoprotein-Mediated Transport of Itraconazole across the Blood-Brain Barrier
The mechanism for the accumulation of itraconazole (ITZ) in its elimination from the brain was studied in rats and mice. The concentration of ITZ in liver tissue declined in parallel with the plasma ITZ concentration until 24 h after intravenous injection of the drug (half-life, 5 h); however, the ITZ in brain tissue rapidly disappeared (half-life, 0.4 h).

17. Influence of molecular weight of DNA on the determination of anti-DNA antibodies in systemic lupus erythematosus (SLE) sera by radioimmunoassay.
Using a radioimmunoassay (RIA) based on the Farr technique with radioactively labeled 3-H-DNA for quantitative measurements of anti-DNA antibodies in sera of patients with systemic lupus erythematosus (SLE), the influence of molecular weight of DNA (ranging from 0.1 times 10-6 to 22.0 times 10-6 daltons) on binding and precipitation in this system has been i

18. Exercise-induced changes in plasma potassium and the ventilatory threshold in man.
1. It has been reported that, during incremental exercise testing, the patterns of change in ventilation (VE) and arterial K+ (Ka+) are similar, suggesting that changing Ka+ may lead to the phenomenon of the ventilatory threshold through its action on the peripheral chemoreceptors. 2. Expiratory ventilation, oxygen consumption, CO2 production (VE, VO2, VCO2)

19. Population Pharmacokinetics of Lamivudine in Adult Human Immunodeficiency Virus-Infected Patients Enrolled in Two Phase III Clinical Trials
Lamivudine population pharmacokinetics were investigated by using nonlinear mixed-effect modelling (NONMEM) analysis of data from 394 human immunodeficiency virus (HIV)-infected patients treated with lamivudine (150 to 300 mg every 12 h) in two large, phase III clinical efficacy-safety trials, NUCA3001 and NUCA3002. Analyses of 1,477 serum lamivudine concent

20. Ozone inactivation of Cryptosporidium parvum in demand-free phosphate buffer determined by in vitro excystation and animal infectivity.
Inactivation of Cryptosporidium parvum oocysts by ozone was performed in ozone demand-free 0.05 M phosphate buffer (pH 6.9) in bench-scale batch reactors at 7 and 22 degrees C. Ozone was added to each trial from a concentrated stock solution for contact times ranging from 5 to 15 min. The viability of the control and treated oocysts was determined by using i

21. Calcium released by photolysis of DM-nitrophen triggers transmitter release at the crayfish neuromuscular junction.
1. Spontaneous and evoked transmitter release at the crayfish neuromuscular junction were potentiated in response to photolytic release of calcium from the 'caged' calcium compound DM-nitrophen, which had previously been injected into presynaptic terminals. 2. The amount of calcium released from DM-nitrophen photolysis depends on the concentration of DM-nitr
