1. Sunscreen lotions in the dermatological prescription: review of concepts and controversies
Abstract The skin is regularly exposed to several environmental aggressions, including solar radiation, whose biological effects can induce sunburn, dyschromia, skin aging and cancer. Among the photoprotection measures, sunscreens comprise a relevant part of the strategy aimed to prevent solar radiation damage and, for effective action, the patient must adhe

2. Nitrogen Oxides Levels in the Atmosphere of Different Brazilian Urban Centers, by Passive Sampling
Urban air pollution is still an emerging environmental problem, it causes damage to health and is difficult to be controlled in urban centers. The population of large metropolises is often exposed to concentrations of nitrogen oxides (NOx), mainly due to vehicle emissions. Epidemiological studies claim that exposure to these oxides is strongly correlated wit

3. DURABILITY OF HDPE GEOMEMBRANES: AN OVERVIEW
The polymer demand for geotechnical applications has been growing. The geomembrane is a geosynthetic, manufactured, polymeric product and is often specified in environmental projects. Geomembranes started to be used in the 1930s but became more widespread in the 1940s. In the 1970s, geomembranes began to be specified for landfills. Over the past forty years,

4. Aspectos genéticos do envelhecimento e doenças associadas: uma complexa rede de interações entre genes e ambiente
Resumo O envelhecimento é um processo dinâmico, no qual ocorrem modificações do nível molecular ao morfo-fisiológico, logo após a maturidade, que induzem ao declínio orgânico, aumentando a susceptibilidade e vulnerabilidade a doenças e à morte. A genética do envelhecimento dedica-se ao estudo da contribuição hereditária da espécie e sua inter

8. Active ingredients, mechanisms of action and efficacy tests of antipollution cosmetic and personal care products
Urban population around the globe is direct exposed to the pollution caused by several sources (vehicles, industries, smokes etc.) and primary pollutants are divided in particulate matter and toxic gases. Current researches in populous countries indicated that exposure to pollution could affect sebum composition, stratum corneum quality and signs of skin agi

9. Materiales eco-compatibles reforzados a base de almidón de mandioca para aplicaciones agronómicas
ABSTRACT Plastic mulch is used in various crops production in order to increase yield, extend growing season, weed control, increase fertilizers efficiency and improve soil conditions. However, since such plastics removal and disposal represent not only an additional cost, but also a source of environmental pollution, interest in starch-based materials as a

10. Role of non-coding RNAs in non-aging-related neurological disorders
Protein coding sequences represent only 2% of the human genome. Recent advances have demonstrated that a significant portion of the genome is actively transcribed as non-coding RNA molecules. These non-coding RNAs are emerging as key players in the regulation of biological processes, and act as "fine-tuners" of gene expression. Neurological disorders are cau

12. Effectiveness of Arsenic Co-Precipitation with Fe-Al Hydroxides for Treatment of Contaminated Water
ABSTRACT Wastewater treatment is a challenging problem faced by the mining industry, especially when mine effluents include acid mine drainage with elevated arsenic levels. Iron (hydr)oxides are known to be effective in removal of As from wastewater, and although the resulting compounds are relatively unstable, the presence of structural Al enhances their st
