Gelatin-based membrane containing usnic acid-loaded liposome improves dermal burn healing in a porcine model.

There are a range of products available which claim to accelerate the healing of burns; these include topical agents, interactive dressings and biomembranes. The aim of this study was to assess the effect of a gelatin-based membrane containing usnic acid/liposomes on the healing of burns in comparison to silver sulfadiazine ointment and duoDerme dressing, as well as examining its quantification by high performance liquid chromatography. The quantification of the usnic acid/liposomes was examined using high performance liquid chromatography (HPLC) by performing separate in vitro studies of the efficiency of the biomembranes in terms of encapsulation, drug release and transdermal absorption.

Silver Nanocomposite Biosynthesis: Antibacterial Activity against Multidrug-Resistant Strains of Pseudomonas aeruginosa and Acinetobacter baumannii.

Bacterial resistance is an emerging public health issue that is disseminated worldwide. Silver nanocomposite can be an alternative strategy to avoid Gram-positive and Gram-negative bacteria growth, including multidrug-resistant strains. In the present study a silver nanocomposite was synthesized, using a new green chemistry process, by the addition of silver nitrate (1.

[Ethical issues in a market dispute between clinical laboratories and a health plan: case report].

In Brazil the private health plans appear as an alternative to the public health assistance. This segment suffered great intensification in the seventies and eighties, culminating in the entry of large insurance company in the scenario of supplementary medicine. Quickly, the service providers associated with these insurance companies, consolidating them in the market and triggering a relationship of dependency.

[Trichomoniasis: prevalence in the female gender in 2004-2005 in Sergipe State, Brazil].

Trichomoniasis is a disease caused by the protozoan Trichomonas vaginalis, which initiates a wide variety of clinical manifestations. It may be associated with human immunodeficiency virus, cervical cancer, infertility and other diseases. Its incidence ranges from 20% up to 40% in Brazil.

[Occurrence of enteroparasitosis in carriers of mental disease assisted at São Marcello nursing home in Aracaju, Sergipe State].

The interhuman transmission, low level of personal hygiene, coprophagic habits, among others, may contribute to the dissemination of enteroparasitosis in individuals with mental diseases. The object of this paper was to verify the occurrence of enteroparasitosis in individuals with mental diseases assisted at São Marcello Nursing Home in Aracaju, Sergipe State, in the period between February and May at 2006, and track epidemiological aspects of the transmission. So, coproparasitologic exams were performed, and samples were manipulated by Hoffmann, Pons or Janner (1932) technique.
