1. Bacterial Cellulose Membranes as a Potential Drug Delivery System for Photodynamic Therapy of Skin Cancer
The development of drug delivery systems for photodynamic therapy (PDT) is increasingly demanded due to the hydrophobicity presented by most of photosensitizers molecules. Bacterial cellulose (BC), a highly pure cellulose produced by bacteria, possesses the essential features for applications in drug delivery systems, such as large surface area and excellent

2. Skin microcirculatory changes reflect early the circulatory deterioration in a fulminant sepsis model in the pig
PURPOSE: In the pathophysiology of sepsis tissue perfusion dysfunction is a crucial driving force. Thus the early recognition is highly important. Concerning the early hours of bacteremia, and the systemic inflammatory response reaction leading to sepsis we aimed to investigate the micro- and macrocirculatory changes. METHODS: In 20 juvenile Hungahib pigs w

3. Nanoparticles containing curcuminoids (Curcuma longa): development of topical delivery formulation
Solid lipid nanoparticles incorporating Curcuma longa L., Zingiberaceae, curcuminoids were produced by the hot melt emulsion method. A Box–Behnken factorial design was adopted to study the nanoparticles production at different levels of factors such as the percentage of curcuminoids, time of homogenization and surfactant ratio. The optimized nanoparticles

4. Laboratory animals and respiratory allergies: The prevalence of allergies among laboratory animal workers and the need for prophylaxis
OBJECTIVE: Subjects exposed to laboratory animals are at a heightened risk of developing respiratory and allergic diseases. These diseases can be prevented by simple measures such as the use of personal protective equipment. We report here the primary findings of the Laboratory Animals and Respiratory Allergies Study regarding the prevalence of allergic dis

5. Anti-candidal activity of Astragalus verus in the in vitro and in vivo guinea pig models of cutaneous and systemic candidiasis
This study was design to evaluate the anti-candidal activity of Astragalus verus Olivier, Fabaceae (Av). The GC/MS analysis of essential oils of Av showed that aqueous extract contains thymol while hexadecanoic acid, 1,2-benzenedicarboxylic acid, diisooctyl ester and phytol were found as major components of methanol and acetone extracts. The aqueous extract

6. Fungal microbiota isolated from healthy pig skin / Microbiota fúngica isolada da pele de suínos sadios
Background: Researches have been developed to observe the normal microbiota of different animal species. This subject is of major importance for the control of potential infection risks. Fungi can be found in various substrates, foodstuffs (cereals, meat, milk, vegetables) and also in the skin, mucosae, respiratory and gastrointestinal tracts of animals. Wit

7. Avaliação da penetração cutânea de nanocápsulas de isotretinoína por tape stripping in vitro em pele humana e suína / Assessment of cutaneous penetration of isotretinoin-loaded nanocapsules by tape stripping in vitro in human and pig skin
Objetivos: objetivo geral deste trabalho foi avaliar a penetração cutânea da isotretinoína nanoencapsulada e livre utilizando técnicas de microdiálise e tape stripping in vitro. Métodos: A viabilidade da utilização da técnica de microdiálise para avaliar o perfil farmacocinético da isotretinoína após aplicação tópica foi investigada através

8. Extração e caracterização de gelatina de pele de tilapia e aplicação como agente encapsulante de oleo de salmão em microparticulas obtidas por coacervação complexa. / Extraction and characterization of fish skin gelatin and application as encapsulate agent of salmon oil in microparticles obtained by complex coacervation.
Two great challenges in the pisciculture production chain are the use of by-products generated during the fish processing and the production of more attractive microparticles for fish larvae feeding. The aim of this work was to extract and to characterize gelatin from tilapia skin to use it as a substitute of mammalian gelatins in the formation of matrix of

9. Analise histologica do aparato venenifero e caracterização farmaco-bioquimica da peçonha de Vitalius dubius (Araneae, Theraphosidae) / Histological analysis of the venom apparatus and biochemical and pharmacological characterization of venom from Vitalius dubius (Araneae, Theraphosidae)
Vitalius dubius is a medium-sized, non-aggressive tarantula found in southeastern Brazil. In this work, we examined the histological organization of the venom apparatus of V. dubius and investigated some biochemical and pharmacological properties of this spider´s venom. The venom apparatus consisted of two chelicerae fitted with large fangs for prey immobil

10. Padronização de um teste de potência de toxóide de Clostridium septicum em linhagem contínua de célula
Clostridium septicum is the pathogen that causes the malignat edema. Because of its strong cytotoxic alpha toxin, infections are often lethal. To prevent losses in animal, vaccination with alpha toxóide vaccines is carried out. The potency test of the vaccines have to be done by neutralization test in mice or intradermally into guinea-pig skin. An alternati

11. Rheology and transition shapes of elastic liposomes in nanopores membranes / Reologia e transição de formas de lipossomas elasticos em membranas de nanoporos
In this work, liposomes prepared with comercial egg lecithin and octaoxyethylenelaurate-ester (PEG-8L) were characterized and studied in respect to PEG-8L incorporation, shape transitions, elasticity and rheology in nanopores membranes. Conventional liposomes (without PEG-8L) were used as control. The concentrated caffeine, extracted of guarana seeds, was in

12. Estratégias para prospecção e predição de peptídeos bioativos
Chapters one and two deal with the isolation and identification of bioactive peptides from the skin secretion of Phyllomedusa hypochondrialis. The first chapter demonstrates the use of protemic techniques, mainly mass spectrometry, for the study of bradykinin related peptides (BRPs) present in the amphibians secretion and freshly dissected skin fragments.
