ASPECTOS GEOLÓGICOS E TECNOLÓGICOS DO GRANITO PRETO PIRACAIA – SP

A rocha ornamental chamada Granito Preto Piracaia constitui o nome comercial dos monzonitos ineqüigranulares de granulação fina, fina/média e média a localmente porfiríticos, de coloração cinza a cinza-escura do Maciço Piracaia. São rochas homogêneas, mas apresentam localmente pequenas variações composicionais. Encontram-se cortadas por veios de composições quartzo-feldspáticas, quartzosas ou sieníticas. As rochas apresentam fraca anisotropia, definida por uma foliação milonítica NE-SW de médio a alto ângulo e famílias de fraturas que apresentam orientações principais NNE-SSW/subvertical, E-W/subvertical, NW-SE/subvertical e suborizontal. Localmente apresentam-se fortemente orientadas, próximas às zonas de falhas. Os parâmetros tecnológicos físicos e físico-mecânicos e petrográficos do Monzonito Piracaia são próximos ou superam os valores médios dos melhores “granitos pretos brasileiros”, permitindo classificá-lo como ideal para revestimento em ambientes internos ou externos. Homogeneidade, coloração escura e fraca alterabilidade dos minerais constituintes valorizam o padrão estético como rocha ornamental.

O pop rock e a escritura poética em Voyages de l’Autre Côté, de Jean-Marie Gustave Le Clezio

A literatura contemporânea expressa o rompimento das fronteiras entre a cultura erudita e a cultura de massa ou comercial, criando formas híbridas que convivem no interior do texto. No romance Voyages de l’autre cote (1975), de Jean-Marie Gustave Le Clézio, as canções do pop rock embalam as viagens da fada Naja Naja e de seus amigos em busca do ‘outro lado’. Desta forma, a impregnação da música popular à escritura poética, parece ajudar a libertar a imaginação, preparando as personagens para o encontro do infinito sensível.

Rock in Rio – um festival (im)pertinente à música brasileira e à redemocratização nacional

A análise histórica sobre a realização do Rock in Rio (Rio de Janeiro, 1985), evento musical que contou com bandas e cantores nacionais e internacionais, permite trazer, além de dados históricos sobre a inédita concretização de um megaevento musical no Brasil, elementos de compreensão acerca da discussão sobre o Festival bem como o próprio rock nacional oitentista no período de redemocratização política brasileira. Pois, as críticas ao Rock in Rio partiram tanto de membros da Igreja Católica quanto perpassaram o campo musical e político, sempre respaldadas, aliás, em reações em defesa da “autêntica” música brasileira contra a “invasão” do rock, bem como sobre o suposto teor alienante e alienado das esferas e estruturas do rock. Além disso, este artigo busca refletir sobre mais um velho-novo gênero musical nos primeiros e mancos passos da redemocratização política brasileira.

Multiple Ornamental Uses of Costus stenophyllus Standl. & LO Williams

Costus stenophyllus or bamboo costus, despite its high ornamental potential, is still little known in the cut flower and ornamental plant market. The bamboo costus is a spiral ginger admired for its beautiful stems that are lined with brown colored alternating bands. This costus has rather straight and upright stems. Conical red inflorescences, which resemble the head of a snake, emerge from the base of the plants. The flowers are light yellow and emerge between the red scales on the rather long-lasting, attractive inflorescences. This study was carried out to evaluate the possibility of using these species as a garden plant, cut flower and cut stem. Thus, the characterization was made based on 28 characters of the plant, the leaves, the flower stem, the flowers, as well as season blooming characteristics and flower postharvest longevity.

Mechanical strain induces the production of spheroid mineralized microparticles in the aortic valve through a RhoA/ROCK-dependent mechanism

Calcific aortic valve disease (CAVD) is a chronic disorder characterized by an abnormal mineralization of the leaflets, which is accelerated in bicuspid aortic valve (BAV). It is suspected that mechanical strain may promote/enhance mineralization of the aortic valve. However, the effect of mechanical strain and the involved pathways during mineralization of the aortic valve remains largely unknown. Valve interstitial cells (VICs) were isolated and studied under strain conditions. Human bicuspid aortic valves were examined as a model relevant to increase mechanical strain. Cyclic strain increased mineralization of VICs by several-fold. Scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analyses revealed that mechanical strain promoted the formation of mineralized spheroid microparticles, which coalesced into larger structure at the surface of apoptotic VICs. Apoptosis and mineralization were closely associated with expression of ENPP1. Inhibition of ENPP1 greatly reduced mineralization of VIC cultures. Through several lines of evidence we showed that mechanical strain promoted the export of ENPP1-containing vesicles to the plasma membrane through a RhoA/ROCK pathway. Studies conducted in human BAV revealed the presence of spheroid mineralized structures along with the expression of ENPP1 in areas of high mechanical strain. Mechanical strain promotes the production and accumulation of spheroid mineralized microparticles by VICs, which may represent one important underlying mechanism involved in aortic valve mineralization. RhoA/ROCK-mediated export of ENPP1 to the plasma membrane promotes strain-induced mineralization of VICs.

Parasitic infections in ornamental cichlid fish in the Peruvian Amazon

The aim of this study was to evaluate the prevalence and seasonal distribution of the main parasite species in Amazonian ornamental cichlids that affect their trade. The study was conducted from August 2007 to September 2009. We sampled 3042 specimens from 9 different species, of which 9.47% had at least one type of external parasite. 81.25% of the cases occurred in the dry season. Crenicichla anthurus (28.57%) was the most parasitized, followed by Aequidens diadema (26.32%), Pterophyllum scalare (22.69%), Cichlasoma sp. (9.52%), Apistogramma sp. (3.88%) and Symphysodon aequifasciatus (3.66%). Monogenea was the most abundant group of parasites, occurring in 66.67% of the cases, of which 96.88% occurred in the dry season. This parasite infested 95.68% of Pterophyllum scalare, 76.67% of Apistogramma sp, 33.33% of Cichlasoma sp. and 23.81% of Symphysodon aequifasciatus cases. Ichthyophthirius multifiliis infested 100% of Aequidens diadema, 76.19% of Symphysodon aequifasciatus, 66.67% of Cichlasoma sp, 41.67% of Crenicichla anthurus and 23.33% of Apistogramma sp cases. Myxosporidia infested 58.33% of Crenicichla anthurus. Trichodina infested 4.32% of Pterophyllum scalare. The prevalence of these parasites is related to the season, preferred habitat, fish behavior, individual susceptibility and handling of animals during transportation by fishermen.
