3. Photochemoprotective effect of quercetin incorporated in microemulsion against skin damages induced by ultraviolet irradiation / Efeito fotoquimioprotetor de quercetina incorporada em microemulsão contra os danos na pele causados pela radiação ultravioleta
The ultraviolet radiation (UVR) exposition may lead to the skin oxidant/antioxidant imbalance injuring its integrity and leading to several disorders, such as ageing and skin cancer. Considering the close relationship between the increase in oxidative stress and UV-induced skin damages, together with the fact that epidemiological studies indicate that the us

5. Estudo dos efeitos biológicos de uma desintegrina recombinante do veneno da serpente Bothrops alternatus, DisBa-01, sobre a musculatura da parede abdominal após indução de hérnia incisional em ratos
INTRODUCTION: The incisional hernia (IH) is one of the most frequent complications after laparotomy, causing high rates of re-operations. Advances in suture material, in the guidelines for incisions, in the techniques of closure and use of dentures (screens), have failed in the elimination of this surgical complication. In this context, advances in the under

7. ObtenÃÃo, caracterizaÃÃo e avaliaÃÃo microbiolÃgica de uma nova forma farmacÃutica contendo hidroquinona
Hydroquinone (HQ) is a drug reported to possess manifold biological activities, such as depigmenting, antimicrobial and antitumour properties. The PluronicLecithin Organogel (PLOme) is a phospholipidic microemulsion particularly implied when a high cutaneous permeability and systemic absorption of a drug is suitable. Once that HQ is highly unstable i

8. Physicochemical Characteristics, Cytotoxicity, and Antioxidant Activity of Three Lipid Nanoparticulate Formulations of Alpha-lipoic Acid
Exogenously supplied alpha-lipoic acid (LA) has proven to be effective as an antioxidant. In an effort to develop a water-soluble formulation for topical administration, LA was formulated in the form of solid lipid nanoparticles (SLN), nanostructure lipid carriers (NLC), and nanoemulsion (NE) and characterized in terms of physical and biological properties.

9. Dendrimers, a New Class of Candidate Topical Microbicides with Activity against Herpes Simplex Virus Infection
Dendrimers are large highly branched macromolecules synthesized from a polyfunctional core. They have shown a variety of biological properties, including, in some instances, antiviral activity. In this study, five dendrimers were evaluated for in vitro activity against herpes simplex virus (HSV) types 1 and 2 by cytopathic effect (CPE) inhibition and plaque

10. Synthetic pyrethroid insecticides: a dermatological evaluation.
Synthetic pyrethroids are lipophilic insecticides whose biological activity seems to be directly related to their chemical structure. In this investigation differences in cutaneous sensation were detected by human participants between synthetic pyrethroids with a cyano group in the (S)-configuration of the 3-phenoxybenzyl alcohol of their molecular structure

11. Nerve growth factor: stimulation of polymorphonuclear leukocyte chemotaxis in vitro.
Topical application of mouse nerve growth factor (NGF) to superficial skin wounds of mice has previously been shown to accelerate the rate of wound contraction. Results of the present study reveal that NGF in the presence of plasma is also chemotactic for human polymorphonuclear leukocytes in vitro, and the concentration of NGF required for this effect is si

12. Recovery of the Decorin-Enriched Fraction, Extract (D), From Human Skin: An Accelerated Protocol
The original extraction procedure of Engel and Catchpole [1] has often been used to recover decorin-enriched material from the skin. This material has a strong inhibitory effect on fibroblast proliferation, and clearly suppresses it in skin except after the first 5–6 days of wounding when new scaffold material is required. The aim of our present study has
