Ácido glicólico: Agente despigmentante e rejuvenescedor

The skin pigmentation caused by ultraviolet light irradiation as a defense against the carcinogenic action of solar light may lead to early skin aging and to hyperchromia, which treatment requires the use of photo-protective, depigmenting and rejuvenating agents. Recently, there have been used many substances for the prevention and/or treatment of skin aging as well as to lowering the skin pigmentation. Glycolic acid is the alpha-hydroxy acid most commonly used in cosmetic and dermatological prepatations. This use is due to its depigmentating and rejuvenating properties and its efficacy at different concentrations, when incorporated to different kind of excipients.

Emprego do reagente de fenton como agente coagulante na remoção de substâncias húmicas de água por meio da flotação por ar dissolvido e filtração

Fenton 's reagent was used as coagulant agent to treat water with high true color (100 ± 5 HU) caused by the introduction of humic substances extracted from peat, using dissolved air flotation. The pair value of coagulant dosage x coagulation pH was optimized to posterior construction of coagulation diagrams, reaching apparent color removal efficiency slightly superior to 60%. It was tried to simulate a treatment with complete cycle, carrying out an experiment with sand filtration after flotation, obtaining an effluent with excellent quality, presenting remnant apparent color, turbidity and absorbance of 253.7 nm less or equal to 2 HU, 0.40 TU and 0.009 cm -1, respectively, and residual total iron < 0.005 mg/L and DOC < 0.001 mg/L.

A identidade do agente comunitário de saúde: Uma abordagem fenomenológica

The structure of Brazil's National Health System (SUS) is being firmed up through programs adding a new element to its multi-professional healthcare teams: Community Healthcare Agents. This study examines psycho-social factors that are significant for the construction of this identity, from the standpoint of these Community Healthcare Agents, using the hermeneutic phenomenology of Paul Ricoeur as its reference methodology. The subjects of this survey were seven Community Healthcare Agents who were asked during interviews (with informed consent and after approval by the Research Ethics Committee) to: 'Tell me about your experience as Community Healthcare Agent'. The analysis of their replies indicated the following topics: previous experience; capacity-building for the job; bonding; building up expertise; gratifying experience; feelings of power(lessness); communications; daily work routines, personal growth; criticisms of the institution; user-agent experiences; and insertion into the social reality. The overall analysis disclosed the phenomenon through the convergence and divergence of the grouping of these topics, viewed from the standpoint of these Community Healthcare Agents and the psycho-social aspects constructing their identity.

Avaliação da transferência de imunidade passiva em cordeiros com até 30 dias de idade

The aim of this study was to determine the serum concentrations of immunoglobulin G, TP and the γ globulin electrophoretic fraction, as well as the enzymatic activities of GGT and ALP. This was done in order to explore the possibility of using changes in activities of these enzymes as indirect indicators of adequate humoral immunity and/ or failure of immune passive transfer in lambs. Pearson correlation was performed between variable of four groups of age during the first 30 days of life. Blood samples (191) from lambs from 21 different farms in Araçatuba region- São Paulo. The following tests were perfomed: radial immunodiffusion, spectrophotometry and electrophoresis to stain the amount of IgG, TP and γ globulin, respectively. GGT and ALP values were determinate using commercial kits. There was a statistically significant correlation between ALP and GGT. The same correlation was observed from TP, IgG and GGT. A positive γ globulin correlation was found between GGT, IgG and TP. ALP activity cannot be used as an indicator of immune passive transfer.
