Este artigo apresenta uma reflexão sobre a pluralidade de conceitos que as imagens envolvem (desde o mundo antigo até os dias de hoje), sua concepção como uma representação material e imaterial e, finalmente, a fotografia como uma possibilidade de imagem construída. Refletimos sobre as potencialidades das fotografias como imagens que contam histórias e representam lugares, que relatam os tempos e registram espaços transformando o passado em nosso contemporâneo. Especificamos que as fotografias revelam o próprio olhar do fotógrafo. Neste sentido, apresentamos o contexto que originou a produção fotográfica de Tony Miyasaka para compreender um pouco da história e da percepção dos lugares do município paulista de Ribeirão Preto.

Proposal of this paper is to reflect on conceptual plurality involved by images (since Antiquity until our times), their conception as a material and immaterial representation and, last but not least, photography as a possibility of a made up image. The paper reflects on pictures as images that can tell stories and represent places, so that they can translate the past into our present. The paper states that pictures show their makers' perceptions. As a case study, we present the context that originated Tony Miyasaka photographic production, in order to understand the history of the city of Ribeirão Preto, in São Paulo State, through pictures representing its space and places.

A partir da descrição e da análise de um evento realizado em 2007 - uma exposição artística, cultural e científica -, são observados potencialidades e desafios das atividades de mediação cultural, com ênfase em seus aspectos formativos e educacionais.

The work examines some of the theoretical and practical implications of the concept of cultural and information mediation. From the description and analysis of an event held in 2007 - an exhibition artistic, cultural and scientific - are observed potentials and challenges of the activities of cultural mediation, with emphasis on training and educational aspects.

Background:  Burning mouth syndrome (BMS) is a burning and painful sensation of the mouth and perioral tissues. Despite several research its causes remain unknown. The treatment of BMS continues to be a challenge. This study investigated the relation between allergy to metals and long-term outcomes in 5 patients with BMS.Methods:  We studied 12 consecutive patients who had received a diagnosis of the BMS (ranging in age from 35 to 71). Mean duration of BMS symptoms was 10 months. We did patch-testing in all patients with dental series. We measured the saliva metal concentrations in each subjects. Of the 12 patients studied, 5 had symptoms which appeared to be related to type 3 BMS. Thus, they were assigned to total metals alloy removal procedures because allergic to at least one metal and had high levels of metals in saliva. No subjects had been receiving drug therapy. The primary outcome was the relief of BMS symptoms. Patients were followed for an average of 1.6 years.Findings:  Of the 5 patients who underwent to total metal alloy removal, 4 had a complete remission and one had showed notable improvement of his symptoms. Three patients were allergic to mercury. Two patients showed an allergy to gold. The saliva mercury and gold levels were significantly over the threshold limit. We also noted in three patients a full recovery of systemic dermatologic manifestations associated with BMS.Conclusions:  We believe that our exploratory investigation adds evidence that allergy to dental metals are involved in BMS.

Background:  Several lines of evidence indicate a potential association between oral lichen-reactions and the presence of dental amalgam fillings.Aim:  We examined the relation between oral lichen reaction cases and the site of amalgam fillings in the oral cavity.Methods:  We conducted an observational study in 5 consecutive patients who had OLR and underwent to dental amalgam replacement. The number of total amalgam surfaces and OLR sites were charted. Saliva samples were taken and levels of total mercury were measured by CV-AAS method. Also we did patch-testing with dental series in all patients. Results: Our observational study revealed that oral lichen reactions may not have an association with the physical proximity the mercury tooth fillings. Unexpectedly, we noted a complete remission in patients with OLR (n = 5). The patients with OLR presented allergies to mercury (n = 4) or gold (n = 1). All patients were negative for HCV/HBV and they had not been taking any drug-induced lichenoid mucositis.Findings:  In this case report series no topographical association was found between OLR and the dental amalgam fillings. All OLR cases were in full recovery after total amalgam removal within three months. Saliva mercury concentrations were significantly elevated in all subjects. After amalgam removal the mercury levels were undetectable. We suggest that dental amalgam removal is important therapeutic option in OLR cases even if the lichenoid lesions are not adjacent to dental amalgam restorations.

A series of experiments was performed on lyophylized melanosomes in order to analyze the melanin in the natural state as polymerized into these organdies and to verify in such biological amorphous material the possibility of obtaining intensity scattering curves from which Bragg distances can be calculated. The results confirm the feasibility of the method and show that melanins in melanosomes maintain many structural features of the purified form and that the biochemical composition of the organelles can be responsible for the observed differences in the diffractograms. The presence in melanosomes of supramolecular paracrystalline aggregates was also clearly demonstrated.

The availability of NMR spectrometers operating in cross polarization/magic angle spinning (CP-MAS) has provided a powerful tool for the structural elucidation of insoluble materials. In this 13C NMR study of eumelanins we report the first direct evidence of the presence of different chemical functionalities in synthetic and natural eumelanins. These spectra contain useful information for the characterization of melanins from different sources.

A new technique, based on the measurement of the phase angle of the photoacoustic signal, was used for investigating the absorption spectra of melanins in the dry state. The main advantages of such a method are the insensitivity to scattering of the light and the applicability to nontransparent or highly adsorbing and thermally thick samples. The spectra obtained on different kinds of natural and synthetic melanins show much more details than the corresponding ones obtained spectrophotometrically on aqueous suspensions of the pigment.Some relevant features of the spectra still cannot be interpreted, yet we were able to show the presence in eumelanins of dopachrome at 475 nm and melanochrome at 540 nm, and in pheomelanins of compounds previously isolated from red chicken feathers. Moreover, the well known trend of the optical absorption, i.e., its decrease with increasing wavelength, was unambiguously confirmed.
