1. Evaluation of ex vivo melanogenic response to UVB, UVA, and visible light in facial melasma and unaffected adjacent skin,
Abstract Background: The independent role of solar radiation in the differential melanogenesis between melasma and adjacent skin is unknown. Objectives: To assess the melanogenic responses of skin with facial melasma and of the adjacent skin to UVB, UVA, and visible light, in an ex vivo model. Methods: This was a quasi-experimental study involving 22 pati

2. UVB, UVA, and visible light (blue-violet range) transmittance of clothing used in Brazil,
Resumo A adoção do marco teórico marxista nos cursos de Serviço Social configura-se como parte fundamental da contestação ao conservadorismo na prática profissional. Contudo, o cotidiano do fazer profissional, pautado pelos interesses hegemônicos que demandam o trabalho dos assistentes sociais, segue apresentando a contradição entre os limites enco

3. Standardization of organoid culture for evaluation of melanogenesis induced by UVB, UVA and visible light,
Abstract Background: Organoid cultures are primary cultures that maintain architectural characteristics and the relationships between cells, as well as the extracellular matrix. They are alternatives for pathophysiological or therapeutic investigation rather than animal and in vitro tests. Objective: Development of a cutaneous organoid culture model, aimin

4. Transmittance of UVB, UVA, and visible light (blue-violet) among the main Brazilian commercial opaque sunscreens,
Abstract These are cutaneous diseases caused by insects, worms, protozoa, or coelenterates which may or may not have a parasitic life. In this review the main ethological agents, clinical aspects, laboratory exams, and treatments of these dermatological diseases will be studied.

5. Layered double hydroxides as fillers in poly(l-lactide) nanocomposites, obtained by in situ bulk polymerization
Abstract In this study in situ bulk polymerization of L-lactide filled with layered double hydroxides (LDH) was investigated. Four different LDHs intercalated with two different organic anions (salicylate and sebacate) were synthesized and characterized. After characterization, these synthetic layered compounds were used as fillers in poly(L-lactide) (PLLA)

6. Oxidative Modifications in Crystallin Proteins and Lens Epithelial Cells Associated with Photosensitized Reactions Mediated by the Major Chromophore Arising from Glucose Degradation
Deleterious effect mediated by glucose degradation, as a parallel pathway to Maillard reaction, was analyzed in terms of the feasibility of inducing photo-crosslinking in isolated bovine crystalline proteins when exposed to ultraviolet A (UVA)-visible light. These experiments showed evidence supporting the generation of a glucose-derived chromophore (GDC). T

7. Estudo da remoÃÃo e degradaÃÃo dos corantes Remazol Black B e Remazol Red RB 133%, e do fÃrmaco Ganciclovir, com aplicaÃÃo de Processos Oxidativos AvanÃados
The contamination of rivers, seas, lakes and oceans is one of the major problems of modern society, caused in large part by industrial activities. Textile processing, particularly generate great amounts of effluent characterized by a high organic load, strong color and toxic chemical compounds, which, depending on the dye, can also contain mutagenic, carcino

8. Poli(oxido de etileno-co-epicloridrina) : degradação foto-oxidativa e termica, e blenda com polipropileno
Polymers derived from ethylene oxide and epichlorohydrin, like poly(epichlorohydrin-co-ethylene oxide) elastomer, are studied as polymer electrolyte for application in photo-electrochemical devices. These materiaIs present the ability to form complexes with alkali salts, presenting high ionic conductivity. In these devices the conversion of the solar energy

9. Specificity and Photomorphogenic Nature of Ultraviolet-B-Induced Cotyledon Curling in Brassica napus L.
Three general classes of photomorphogenic photoreceptors have been characterized in higher plants: phytochrome, a blue light/ultraviolet (UV)-A photoreceptor(s), and a UV-B sensory system(s). Although a great deal is known about phytochrome and the blue light/UV-A photoreceptor(s), little is known about UV-B detection processes. One reason for this is the la

10. Photosynthetic Response of Seagrasses to Ultraviolet-A Radiation and the Influence of Visible Light Intensity 1
Inhibition of photosynthesis by ultraviolet-A radiation (UV-A, 315-380 nanometers) was examined in three marine angiosperms: Halophila engelmannii Aschers, Halodule wrightii Aschers, and Syringodium filiforme Kütz. Sensitivity to UV-A and photosensitization to UV-A by photosynthetically active radiation (PAR, 380-700 nanometers) were characterized.

11. Transdermal photopolymerization for minimally invasive implantation
Photopolymerizations are widely used in medicine to create polymer networks for use in applications such as bone restorations and coatings for artificial implants. These photopolymerizations occur by directly exposing materials to light in “open” environments such as the oral cavity or during invasive procedures such as surgery. We hypothesized that ligh

12. Sunlight Inactivation of Enterococci and Fecal Coliforms in Sewage Effluent Diluted in Seawater
Inactivation (loss of culturability) by sunlight of enterococci and fecal coliforms within sewage effluent diluted in seawater was investigated in field experiments. In most experiments, 500-ml flasks of pure silica were used to confine activated sludge effluent diluted to 2% (vol/vol) in seawater. Inactivation of bacteria in these flasks (diameter, 0.1 m) w
