As doenças parasitárias, também chamadas de “doenças negligenciadas”, continuam sendo uma grande dificuldade para o desenvolvimento social e econômico dos países mais pobres. Podemos citar como exemplo dessas doenças, a leishmaniose e a doença de Chagas. A leishmaniose é causada por ...

Pullulan as a stabilizer agent of polymeric nanocapsules for drug delivery

Braz. j. pharm. sci; 52 (4), 2016
ABSTRACT Polymeric stabilizers have received attention in the preparation of nanostructured systems due to their ability to enhance formulation stability. Considering this, the objective of this work was to prepare poly(ε-caprolactone) nanocapsules using the pullulan as a polymeric stabilizer. The n...

Gelatin-based microspheres crosslinked with glutaraldehyde and rutin oriented to cosmetics

Braz. j. pharm. sci; 52 (4), 2016
ABSTRACT Glutaraldehyde (GTA) has been extensively used as a gelatin crosslinking agent, however, new natural ones have been suggested as more biocompatible. Polyphenols are possible candidates and the flavonols, such as rutin (RUT), also exhibit potential synergism with sunscreens and antioxidant agents...

Possibility of using apple pomaces in the process of propionic-acetic fermentation

Electron. j. biotechnol; 19 (5), 2016
Background: In 2014, apple production in EU countries amounted to 11.8 million tonnes. A constant increase in the production of these fruits will lead to the accumulation of thousands of tonnes of apple pomace (production waste). The amount of industrial apples is the highest - their proportiononthe mark...
