Saberes em viagem nos manuais pedag��gicos (Portugal - Brasil)

Este trabalho procura sistematizar e aprofundar a problematiza����o acerca do lugar ocupado pelos manuais de Pedagogia, Did��tica, Metodologia e Pr��tica de Ensino utilizados em cursos de forma����o de professores, na produ����o e circula����o intra e internacional do discurso pedag��gico e profissional docente. A reflex��o d�� continuidade a estudos anteriores j�� realizados pelos autores numa perspectiva socioist��rica comparada, no ��mbito de um projeto maior sob o t��tulo: Estudos comparados sobre a escola: Brasil e Portugal (s��culos XIX e XX), financiado na parte brasileira pelo Acordo Capes-ICCTI. Tal colabora����o insere-se tamb��m no ��mbito do Prestige, programa financiado pela Uni��o Europ��ia. O artigo tece considera����es sobre levantamento razoavelmente extenso da literatura produzida sobre manuais escolares e para professores, analisando a predomin��ncia de certos t��picos e de diretrizes espec��ficas de pesquisas na ��rea. Esses elementos ajudam a entender como as produ����es sobre o objeto de estudo foram geradas e postas em circula����o, colaborando para a constru����o da hist��ria da hist��ria dos manuais pedag��gicos e do discurso educacional.

CURCUMINA, O P�� DOURADO DO A��AFR��O-DA-TERRA: INTROSPEC����ES SOBRE QU��MICA E ATIVIDADES BIOL��GICAS

Turmeric, obtained from the dried rhizomes of Curcuma longa (Zingiberaceae), is a golden colored material, commonly used around the world for seasoning and coloring food dishes. Since antiquity, turmeric has been widely used in the treatment of several diseases in traditional Chinese and Indian medicine (Ayurveda), where it is also known by other names such as Kanchani (goddess gold) or also Gauri (having a bright and luminous face), a designation stemming from the gilded appearance of the plant material. Curcumin, the main chemical component of turmeric, is responsible both for its properties as dyes as well as its biological activities. This diarylheptanoid was first isolated almost two centuries ago and had its chemical structure determined in 1910 as being diferuloylmethane. Subsequently, more detailed and relevant data were obtained furthering the understanding of structural features of curcumin. The classical methodology for the synthesis of curcumin and other curcuminoids was described in 1960 by Pabon. Subsequently, different variations on this methodology have been developed, culminating with the synthesis of different curcuminoids. Several studies have been published in recent years on the biological activities exhibited by curcumin including its antioxidant, antitumor, anti-inflammatory, antiviral, antibacterial, antifungal, antimalarial and leishmanicidal activities.

Revisitando el papel del templo en la ciudad: los grandes templos neog��ticos del occidente de M��xico

El trabajo que presentamos quiere analizar el papel de los grandes templos neog��ticos construidos entre el siglo XIX y XX en la trama actual de algunas ciudades mexicanas, tomando como ejemplos de estudio el Templo Expiatorio del Sagrado Coraz��n de Jes��s, en Le��n, en el Estado de Guanajuato y el del templo de San Jos�� Obrero en Arandas en el Estado de Jalisco. Un papel destacado en su actual interrelaci��n con la trama urbana y por el valor simb��lico que los mismos tienen dada su monumentalidad y funci��n para el culto religioso. Ambas son iglesias que quedaron inacabadas por causas pol��ticas y econ��micas y que tras un largo proceso han sido concluidas incorporando las normas del Concilio Vaticano II, convirti��ndose en hitos urbanos con capacidad generar espacios de nueva centralidad para la ciudadan��a.

Syphilis and cirrhosis: a lethal combination in a XIX century individual identified from the Medical Schools Collection at the University of Coimbra (Portugal)

Syphilis is a chronic infection that is categorized by a three-stage progression. The tertiary stage may affect bones and produce distinctive skull lesions called caries sicca. This paper aims to present an unusual case of syphilis associated with a diagnosis of cirrhosis, which was recorded as the cause of death in a 28-year-old female in 1899. The appearance and distribution of the lesions were compatible with acquired syphilis, as observed in the skull from the Medical Schools Collection of the University of Coimbra. However, the cause of death was recorded as "hypertrophic cirrhosis of the liver", this is a condition that is compatible with several liver disorders, including a primary liver disorder, such as cirrhosis provoked by alcoholism, infection of the liver by syphilis pathogens or by damage to the liver from the use of mercury compounds, which was the common treatment for syphilis at the time. This paper represents a contribution to the understanding of the natural evolution of syphilis.

A rota dos estudos sobre a cochonilha em Portugal e no Brasil no s��culo XIX: caminhos desencontrados

For imparting an intense and long-lasting red to fabrics, cochineal remained in high demand during the eighteenth and nineteenth centuries. This period witnessed, accordingly, several initiatives aimed at producing the precious dye: publication of specialized texts, cultivation of the cactus and the insect from which the dye is extracted, and, also, attempts to obtain the secrets of production through espionage. The present paper analyses certain aspects of the measures adopted by the Portuguese government towards Brazil in this field. The work shows how people sought to take part in the network of cochineal production (yet they were unsuccessful most of the time).
