Orientador: Carlos Alan Candido Dias Junior<br>Resumo: As desordens hipertensivas gestacionais são complicações que acometem em torno de 5-10% das gestações. Essas desordens são as maiores causas de morbidade e mortalidade tanto materna quanto fetal. Estudos demonstram redução da biodisponibilidade do óxido nítrico (NO) em doenças hipertensivas gestacionais, tornando uma das condições responsáveis por agravar a disfunção endotelial durante o curso desta doença. Neste sentido, trabalhos demonstram que a administração oral de nitrito de sódio (NaNO2) e a administração de citrato de sildenafil po

Abstract:
The discovery that negatively charged aggregates of C60 fullerene are stable in aqueous environments has elicited concerns regarding the potential environmental and health effects of these aggregates. Although many previous studies have used aggregates synthesized using intermediate organic solvents, this work primarily employed an aggregate production method that more closely emulates the fate of C60 upon accidental release into the environment â extended mixing in water. The aggregates formed via this method (aqu/nC60) differ from those produced using the more common solvent exchange met

Abstract:
Post process application of antimicrobials is one method to control recontamination of Listeria monocytogenes on cooked RTE meat products. This study evaluated the antilisterial effect of externally applied solutions of nisin, buffered solution of sodium citrate supplemented with sodium diacetate (SCSD) and a combined solution of the two antimicrobials on commercial beef frankfurters formulated without antimicrobials. Autoclaved frankfurters were inoculated (104 -105 CFU/g), dipped (5 min, 25 ± 2°C) in treatments consisting of 2000; 4000;or 6000 IU/ml nisin, and buffered solutions of 2.5; 3.0;

Abstract:
Background: A number of anticoagulants are available in clinical use to preserve blood samples in liquid form until a suitable time for laboratory testing. Rotational thromboelastography is usually performed on a blood sample that has been anticoagulated with sodium citrate and then recalcified immediately prior to testing. In our institution we have had shortages of citrated Vacutainer® sample tubes. The use of a single in vitro anticoagulant promises to cut costs, simplify laboratory processes as well as limit the amount of blood drawn from patients. This together with the known problems wit

Abstract:
A precipitação e cristalização de proteínas são operações unitárias amplamente utilizadas na indústria biotecnológica. A formação de precipitado nestas operações é muitas vezes atingida por meio da adição de um sal que diminui a solubilidade da proteína, ou seja, o chamado fenômeno de saltingout. A principal informação para o estudo da precipitação e da cristalização é o diagrama de fases, em que a solubilidade da proteína é apresentada em função das variáveis do sistema (temperatura, pH, concentração de sal). Outra medida importante é o segundo coeficiente virial, que é uma medida indireta da

These nuclei grow in size by assimilating solute from the bulk. Stabilizers or capping agents compete with solute for adsorption on the surface of a growing par
