Biosilicification of loricate choanoflagellate: organic composition of the nanotubular siliceous costal strips of Stephanoeca diplocostata.

2010

SUMMARY Loricate choanoflagellates (unicellular, eukaryotic flagellates; phylum Choanozoa) synthesize a basket-like siliceous lorica reinforced by costal strips (diameter of approximately 100 nm and length of 3 μm). In the present study, the composition of these siliceous costal strips is described, using Stephanoeca diplocostata as a model. Analyses by energy-dispersive X-ray spectroscopy (EDX), coupled with transmission electron microscopy (TEM), indicate that the costal strips comprise inorganic and organic components. The organic, proteinaceous scaffold contained one major polypeptide of mass 14 kDa that reacted with wheat germ agglutinin. Polyclonal antibodies were raised that allowed …

Un contrato inédito de Juan de Juanes. El retablo de la Cofradía de la Sangre de Cristo de Valencia (1539)

2012

This article is based on an unpublished contract signed in 1539 by Vicente and Juan Macip for an altarpiece for the Valencian Brotherhood of the Blood of Christ. The agreement stipulates that Juan, later known as Juan de Juanes, had to paint the scenes. Thus the document reinforces the hypothesis that Juan Macip was the most important painter in the Macip workshop during the 1530’s. It also fills a documental void in between the completion of the Silversmith’s Guild altarpiece (1534-1539) and the contract for the Fuente la Higuera altarpiece (1548). This study also verifies the popularity of the iconography of the seven sheddings of the Blood of Christ and processions of disciplinants.<b…

Un contrato de los Hernandos para la capilla de les Febres de la Seo de Xàtiva en 1511

2006

The contract dated 1511 signed by Fernando Llanos and Fernando Yáñez de la Almedina, Castillian painters known as “the Hernandos,” for the termination of an altarpiece in the chapel of the “Virgen de les Febres” is presented here. This chapel was founded in 1497 in the collegiate church of Jàtiva (Valencia) by Francisco de Borja, Bishop of Teano and Cardinal of Cosenza. Based on this document, a series of hypotheses are put forth concerning the trajectory and works of “the Hernandos” following their execution of the doors of the main altarpiece of the Cathedral of Valencia.<br><br>Se presenta el contrato firmado en 1511 por Fernando Llanos y Fernando Yañez de la Almedina, pintor…

Off-Modern Hybridity in TV Theatre: Theatrical, Cinematic and Media Temporalities in Rupert Goold’s Macbeth (BBC - Illuminations Media, 2010)

2021

Rupert Goold’s screen production of Macbeth – firstly, staged in 2007 and, later, filmed in 2010 – has been studied as an example of the stage-to-screen hybrid corpus of Shakespearean audio-visual adaptations. Thus, much of the critical emphasis on the production has been placed on its filmic qualities. Particularly, the genre film conventions deployed across the film has summoned the attention of Shakespeare on screen scholars and it has been the creators’ intentions to precisely point at Goold’s filmic intertextual repertoire. Given the recent increasing attention to the multiple media and languages employed in stage-to-screen hybrid Shakespearean adaptations and other exchanges between t…

La devoción a san Jorge durante el siglo XVIII en Durango. A propósito de un lienzo conservado en la sacristía de la catedral

2019

ABSTRACT: St. George was one of the best known figures in Christendom, due both to his unique story as well as for the help he gave to the various Spanish kingdoms in the fight against the enemies of Jesus Christ. His cult spread to New Spain where he was known, although not in the same manner as in Europe. But nevertheless, in the cathedral of the bishopric of Durango, the efforts of bishop Pedro Anselmo Sánchez de Tagle interests resulted in St. George being declared patron of the city in 1749 by both civil and ecclesiastical chapters. This event granted the saint another function: the fight against poisonous animals, specifically, the scorpions endemic to the region. As a result, the Sai…

An Interview with Giorgio Grassi

2007

In January 2007, Lucia Tozzi visited Giorgio Grassi's office in Milan. Their conversation touched on Grassi's recent work on Leon Battista Alberti, which is examined here in the context of Grassi's obliquely expressed views on contemporary architecture and the cult of personality. As perhaps the most intellectually rigorous and formally consistent Rationalist architect of his generation, Grassi's work and thinking retain a hermetic aspect, but one notable for its philosophical self-questioning and underlying political commitment.

Embryotoxic potential of persistent organic pollutants extracted from tissues of guillemots (Uria aalge) from the Baltic Sea and the Atlantic Ocean

2002

The Baltic Sea is a heavily polluted area. To assess the current contaminant pressure on the common guillemot (Uria aalge) living there, whole-body extracts of guillemots from the Baltic Sea were prepared and subdivided over six fractions, which differed in composition due to lipophilicity and polarity of the contaminants. The fractions were tested in the chicken embryo assay and compared to fractions of Atlantic guillemot extracts. Fertilized chicken eggs were injected with 0.03, 0.3, or 3 bird egg equivalents (BEQ) of the contaminants present in the fractions and then incubated for 19 d. Endpoints were selected to cover several mechanisms that may play a role in reproductive failures of f…

Effects of air pollution on production of essential oil in Feijoa Sellowiana Berg. grown in the "Italian triangle of death"

2010

The composition of the essential oils of fruits from Feijoa sellowiana grown in the district of Acerra is compared with those collected from unpolluted sites. Essential oils from the fruits of F. sellowiana were analysed by GC/MS. Sixty compounds, representing 96.6% and 97.8% (unpolluted site and Acerra site, respectively) of the oils, were identified. The major constituents were β-caryophyllene (12.4% and 16.8%), ledene (9.6% and 11.1%), α-humulene (6.3% and 8.2%), β-elemene (4.9% and 5.3%) and δ-cadinene (4.7% and 5.2%) in the control site and Acerra site, respectively. The antioxidant components were increased in response to polluted condition. The acetonic extracts of F. sellowiana from…

Soil mutagens are airborne mutagens: variation of mutagenic activities induced in Salmonella typhimurium TA 98 and TA 100 by organic extracts of agri…

2000

As our hypothesis was that soil mutagens are airborne mutagens, possibly modified by soil microorganisms, we checked solvent extracts from agricultural and forest soils collected during late summer in the environment of Mainz, a region highly charged by anthropogenic air pollution, or near Bayreuth, a rural low charged region of Germany, or in a remote region of western Corsica without anthropogenic air pollution for the presence of mutagenicity in Salmonella typhimurium. Levels of mutagenic activities were quantified by calculation of revertants/g from the initial slope of dose-response curves applying tester strains S. typhimurium TA 98 and TA 100 in the absence and presence of an activat…
