Abstract The objective of this study was to determine the influence of nonionic surfactants on the effectiveness of preservatives used in emulsions containing high surfactant content. Mixtures of different concentrations were prepared between polyethoxylated (40) hydrogenated castor oil (PHCO) and polyox...
Introducción. Las sorderas o hipoacusias prelinguales son de etiología genética entre el 60 y el 68% de los casos; de estos, del 20 al 40% son malformaciones del oído interno. De los casos de hipoacusia no sindrómica ligada al X se han descrito siete tipos. De las malformaciones de oído in...

Abstract In this study, microemulsions containing etofenamate were prepared and evaluated as dermal delivery carriers. The developed microemulsions consist of oleic acid, Span 80, Tween 20, Cremophor EL, Transcutol and ethanol. The percentage of etofenamate loading in the microemulsions was 5% (w/w). The...
Bisphenol-A is currently considered an environmental pollutant, capable of interfering in the endocrine system of organisms and causing alterations in its development and reproductive system. An alternative method to the chemical treatment of this pollutant has been the use of oxidative enzymes, especial...

ABSTRACT Objective : to determine the functional and morphological effects at rabbits retina of PS80 concentration used in the preparation of intravitreal drugs. Methods: eleven New Zealand rabbits received a intravitreal injection of 0.1ml of PS80. As control, the contralateral eye of each rabbit rece...
A zidovudina (AZT), fármaco antirretroviral utilizado no tratamento da AIDS, apresenta biodisponibilidade oral em torno de 60% e seu uso prolongado pode ocasionar efeitos tóxicos e tolerância ao tratamento. A lamivudina (3TC), apesar de demonstrar menor citotoxicidade e menor resistência viral, é co...
Abstract Various chemical compounds, including surfactants, when introduced to culture media may increase the permeability of cellular membranes and thereby affect the quantity of metabolites excreted by cells. The aim of the present study was to evaluate the impact of detergents including Triton X-100, ...

The objective of this study was to develop a pharmaceutical O/W emulsion containing plant-derived polyphenol extracts and evaluate its stability and antioxidant activity. O/W emulsions were prepared using ionic surfactant polysorbate 80 (Tween 80®). The odorwas adjusted with few drops of blue sea fragra...
Os autores estabeleceram método polarográfico para determinar ácido Lsascórbico na presença de polissorbato eo ou 80 em produtos de panificação, devido à imprecisão na sua determinação pelos métodos usuais. A oxidação anódica do ácido ascórbíco foi realizada em presença da solução-ta...
