Testo completoNd:YAG Q-Switched laser cleaning of soiled stone at 1064 nm can sometimes result in yellower appearances than other conventional cleaning techniques. This yellowing effect can lead to unsightly colour contrasts if different cleaning techniques are used on the same architectural complex, as is the case for the Valois Portal of the Saint-Denis basilica near Paris. One argument made to explain the phenomenon is that the laser yellowing is linked to the creation of nano-sized irradiation residues through the laser beam interaction with soiling matter such as black gypseous crusts. In this study, a multi-scale analytical method extending to the nanoscale has been used to observe and characterize the neo-formed compounds accountable for the yellow discoloration. Samples of model crusts containing hematite and reconstituted crusts prepared with natural black crust have been synthetized. The natural black crust has been characterized in order to identify the compounds that may react under the laser beam and thus contribute to the yellowing effect. Iron oxides (hematite, magnetite and maghemite) and aluminosilicate fly-ashes originating from coal combustion have been discovered. The chemical and structural nature of irradiation products has then been investigated by several techniques including in particular transmission electron microscopy (TEM) coupled with electronic diffraction and energy-dispersive X-ray (EDX) and electron energy-loss (EELS) spectroscopies. Iron containing nanostructures crystallized in the form of nano-spheres and nano-residues have been evidenced and characterized. By studying thoroughly the colour, the colorimetric properties of the yellowing process have been linked to the nature of the neo-formed compounds. Furthermore a case study on the Valois Portal has completed the research while setting it within the reality of the conservation world. Finally experiments with UV light have shown the promising potentiality of this tool as a remedy to the yellowing effect. In summary, this study has demonstrated that the yellowing phenomenon observed at the macroscale is intimately linked to matter transformations occurring at the nanoscale, induced by the interaction between the laser beam and the iron oxides and fly-ashes found in black crusts

Piedra branca é uma infecção de etiologia fúngica caracterizada pela formação de nódulos restritos a porção extrafolicular dos pelos e cabelos, sendo ocasionada por leveduras do gênero Trichosporon. O diagnóstico é clínico e laboratorial micológico, sendo concluído com a identificação precisa do agente etiológico. Esta pesquisa teve como objetivo elaborar um modelo de infecção in vitro da piedra branca, analisar os aspectos morfológicos e ultraestruturais dos nódulos e seus agentes, e autenticar taxonomicamente os isolados por meio de uma abordagem de identificação polifásica. A infecção dos cabelos foi induzida utilizando 18 isolados do gênero Trichosporon, mantidos na Coleção de Culturas Micoteca URM. Para confirmação taxonômica dos isolados, foi adotada métodos empregados na taxonomia clássica, Espectroscopia de Massa (MALDI-TOF MS) e sequenciamento das regiões ITS (ITS1–5.8s-ITS2), IGS1 (Intergenic spacer) e domínios D1/D2 do rDNA. Foi verificado que 15 (83,33%) dos isolados de levedura foram identificados por meio da Espectrometria de Massa MALDI-TOF MS. Os métodos moleculares foram considerados os mais precisos, possibilitando a identificação dos isolados de levedura como: T. asahii (8), T. faecale (3), T. montevideense (5), T. mycotoxinivorans (1) e Hyphopichia burtonii (1). Os nódulos típicos foram formados por 12 isolados, seis formaram nódulo atípico (Quatro de T. asahii e dois de T. montevideense) e dois não formaram nódulo (um de T. montevideense e um de T. faecale). Os constituintes químicos detectados nos nódulos foram carbono, oxigênio, sódio, cálcio, manganês e magnésio. A consistência friável dos nódulos está relacionada com as baixas concentrações de cálcio e enxofre, conferindo a facilidade de rompimento do nódulo. Neste modelo, foi verificado que temperaturas elevadas e umidade excessiva não estão relacionadas com o desenvolvimento desta tricopatia.
White piedra is a fungal infection caused by Trichosporon species. The clinical condition of this mycosis is the production of white nodules adhered to the hair shaft. The diagnosis take in account the clinical feature and mycological laboratory results, which is finalized with the precise etiologic agent identification. This research aimed to develop an in vitro infection model of white piedra, analyzing the morphological and ultrastructural aspects of nodules and aetiological agents, and to identify the isolates by a polyphase approach. The infection of the hair was induced using 18 isolates of the genus Trichosporon, from the Culture Collection Micoteca URM. To taxonomic confirmation of the Trichosporon isolates, were adopted methods used in the classical taxonomy, Mass Spectroscopy (MALDI-TOF MS) and sequencing of the ITS (ITS1-5.8s-ITS2), IGS1 (Intergenic spacer) and D1/D2 domains of rDNA regions. A total of 15 (83.33%) yeast isolates were identified by mass spectrometry MALDI-TOF MS. Molecular tols were considered more accurate, allowing the identification of all yeast isolates as: T. asahii (8), T. faecale (3), T. montevideense (5), T. mycotoxinivorans (1) and Hyphopichia burtonii (1). Typical nodules were formed by 12 isolates, 6 isolates formed atypical nodules (T. asahii (4) and T. montevideense (2)) and 2 isolates did not formed nodules (T. montevideense (1) and T. faecale (1)). The chemical constituents detected in the nodules were carbon, oxygen, sodium, calcium, manganese and magnesium. The softh consistency of the nodules is associated with the low concentrations of calcium and sulfur, that providing ease disruption of the nodule. In this in vitro infection model, it was observed that the temperatures and humidity were not related to the development of this tricopatia.

CAPEs
Piedra preta é uma micose superficial assintomática, caracterizada pela formação de nódulos rígidos e enegrecidos localizados ao longo do fio capilar. É uma micose considerada rara, inócua, podendo acometer tanto o gênero feminino quanto o masculino em qualquer faixa etária. Piedraia hortae, agente etiológico desta micose, é um fungo filamentoso, demáceo que produz o pigmento melanina, caracterizando uma coloração enegrecida na parede celular e nas estruturas fúngicas. Este pigmento, por sua vez, é caracterizado como um potente fator de virulência, favorecendo, desse modo, seu potencial em causar parasitismo no cabelo. Na literatura, não há referências citando que outros fungos demáceos, que formam ascostroma, ascos e ascosporos, semelhantes ao P. hortae, possam ser agente etiológico dessa feohifomicose. Assim, o objetivo desse trabalho foi avaliar a capacidade de fungos demáceos de formarem nódulos na porção extrafolicular de fios de cabelo humano, semelhantes aos da piedra preta. Foram obtidos onze isolados de fungos demáceos, sendo dez da Coleção de Cultura Micoteca URM, UFPE, os quais estavam preservados sob óleo mineral e posteriormente semeados em meio Àgar Batata Dextrose para estimulação do crescimento; e um isolado proveniente do Laboratório de Micologia Médica. Foram preparadas suspensões dos isolados dos fungos demáceos em 2,0 ml de água destilada esterilizada, ajustada para concentração final de 106 células/mL. Em seguida, vertidos separadamente 0,5 mL de cada suspensão sobre os fios de cabelo contidos nas placas de Petri previamente esterilizada e mantidas a temperatura de 28°C e 37°C. O experimento foi conduzido através de observações macroscópicas e microscópicas dos cabelos durante 40 dias e acompanhado em intervalo de 5 dias. Dois isolados (970 e 3334) mostraram um elevado potencial capaz de causar infecção no fio capilar. Entretanto, oito isolados apresentaram apenas uma colonização. Exophiala dermatitidis e Cladosporium tenuissimo foram capazes de formar nódulos semelhantes ao da piedra preta, porém estruturas de reprodução como ascostroma, ascos e ascosporos, não foram vizualizadas.Todavia, podemos inferir que esses fungos apresentam um potencial capaz de parasitar os fios de cabelo, degradando e destruindo a queratina e os componentes cutiulares, sendo o potente agente de tricomicose.
Black piedra is a superficial mycosis asymptomatic, characterized by the formation of hard lumps and blackened located along the capillary yarn. It is a mycosis considered rare, innocuous and can affect both the female and the male at any age. Piedraia hortae, the etiologic agent of this mycosis, is a filamentous fungus, dematiaceous that making the pigment melanin, featuring a blackish color in the cell wall and the fungal structures. This pigment, in turn, is characterized as a potent virulence factor, facilitating there by the potential to cause parasitic hair. In the literature, there are no references citing that other demáceos fungi that form ascostroma, asci and ascospores, similar to P. hortae, may be etiologic agent of this phaeohyphomycosis. The objective of this paper is to demáceos fungal ability to form nodules in extrafollicular portion of human hair, similar to those of black piedra. Eleven isolates of fungi demáceos, obtained of the Culture Collection URM, UFPE, which were preserved under mineral oil and then plated on potato dextrose agar medium for growth promotion; and one isolated from the Medical Mycology Laboratory. Fungal isolates demáceos suspensions were prepared in 2.0 ml of sterile distilled water, adjusted to a final concentration of 106cells / ml. Then separately poured into 0.5 mL of each suspension over the strands of hair contained in the previously sterile Petri dishes and kept at 28 °C and 37 °C. The experiment was conducted by macroscopic and microscopic observations of the hair for 40 days and monitoring in the range of 5 days. Two isolates (970 and 3334) showed a high potential capable of causing infection in the capillary. However, eight isolates showed only colonization. Exophiala dermatitidis and Cladosporium tenuissimo was capable of forming nodules were similar to those of black piedra; however ascostroma structures such as playback, asci and ascosporos were not displayed. However, we can infer that these fungi have the potential able to parasitize the hairs, degrading and destroying the keratin and cuticulares components, the powerful Trichomycosis agent.
