Production, characterization and kinetic model of biosurfactant produced by lactic acid bacteria

BACKGROUND Biosurfactants are surface active molecules produced by microorganisms which have the ability to disrupt the plasma membrane. Biosurfactant properties are important in the food, pharmaceu tical and oil industries. Lactic acid bacteria can produce cell-bound and excreted biosurfactants. RESULTS...

Efeito da endotoxemia na temperatura corporal, pressão arterial média e nas concentrações de nitrato e lactato plasmáticos em ratos

Na endotoxemia e na sepse alterações nos sinais vitais e em biomarcadores estão presentes e sinalizam o grau de comprometimento fisiológico. Embora a interpretação sobre as concentrações do óxido nítrico (NO) e do lactato plasmáticos na pressão arterial sejam bem estabelecidas na literatura, ...

Hepatic toxicity caused by PLGA-microspheres containing usnic acid from the lichen C ladonia substellata (AHTI) during pregnancy in Wistar rats

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT This study aimed to evaluate the teratogenic and hepatotoxic potential of the usnic acid encapsulated into PLGA-microspheres. In total, 12 female Wistar rats in pregnancy were randomly distributed in the control group (n= 6) that received 1.0 mL of physiological solution and treatment group (n= ...

Is heart rate variability a feasible method to determine anaerobic threshold in progressive resistance exercise in coronary artery disease?

ABSTRACT Background Recent studies have shown that the magnitude of the metabolic and autonomic responses during progressive resistance exercise (PRE) is associated with the determination of the anaerobic threshold (AT). AT is an important parameter to determine intensity in dynamic exercise. Objective...

Biocompatibilidad de células madres mesenquimales de tejido gingival humano en cultivoconun andamiaje de polímero sintético de ácido poliláctico (OPLA)

Int. j. morphol; 32 (3), 2014
La ingeniería tisular se plantea como tratamiento ideal para la regeneración de tejidos con la utilización de andamiajes, células madres y factores de crecimiento. Las células madres de origen gingival plantean ventajas de obtención, mientras que el OPLA 3D permite cultivos de alta densidad celular...
