Abstract In 1972, CAYC (Center for Arte and Communication, Buenos Aires, 1968) opened its exhibition “Hacia un perfil del arte latinoamericano”. The show, organized by the cultural promoter Jorge Glusberg, included 143 pieces by 36 artists from Argentina, Latin America, The United Stated, and Europe. The exhibition, which traveled around different art spaces in the world, attempted to explore, trough heliographic pieces, a conceptualization of “Latin American” under the lens of the regional conflicts amplified by the political struggles in those years. In this article, I will present how this exhibition, despite been sent to Santiago to be exhibited in the National Museum of Fine Arts in 1973, was left forgotten for over 45 years in the museum’s storage due to the coup d’Etat. Today, thanks to the studies of documents, archives and diverse collections, it has been possible to reconstruct this history and study in depth through the analysis of three emblematic artworks.

Resumen En 1972 el Centro de Arte y Comunicación (CAYC), fundado en Buenos Aires en 1968, se inauguró la exposición “Hacia un perfil del arte latinoamericano”. La muestra, organizada por el promotor cultural Jorge Glusberg, incluyó 143 piezas correspondientes a 36 artistas de Argentina, América Latina, Estados Unidos y Europa. La exhibición, que viajó por distintos espacios del mundo, apuntaba a explorar, por medio de obras heliográficas, una conceptualización de “lo latinoamericano”, bajo el lente de las tensiones regionales amplificadas por las luchas políticas de aquellos años. En este artículo se aborda cómo esta exposición, a pesar de haber sido enviada a Santiago en 1973 con la intención de ser expuesta en el Museo Nacional del Bellas Artes (MNBA), quedó olvidada en los depósitos del museo durante más de 45 años, debido al golpe de Estado. Hoy, gracias al estudio de fuentes documentales, archivos y colecciones diversas, se ha podido reconstruir dicha historia, y proponer una lectura en profundidad, a través del análisis de tres obras consideradas emblemáticas.

Sixteen dialkylphosphorylhydrazones were synthesized by condensation of phosphorylhydrazines with substituted isatins. Products were characterized by FTIR, ¹H-NMR, 13C-NMR, and 31P-NMR. Fungicidal activities of these compounds against Rhizoctonia solani and Fusarium oxysporum were also evaluated. Some compounds inhibited the growth of Rhizoctonia solani and Fusarium oxysporum by 43% and 51%, respectively. These compounds exhibited no effects on germination of lettuce seeds (Lactuca sativa L).

INTRODUCTION: Trauma is a well-known leading cause of unnatural death and disability in South Africa. Internationally the trend is moving toward systematised care. AIM: To revise the Trauma Centre Criteria of the Trauma Society of South Africa and align these with the terminology and modern scope of emergency care practice, using best-care principles as a prelude to the development of trauma systems in South Africa. METHODOLOGY: Revision of existing documents of the Trauma Society of South Africa, the Emergency Medicine Society of South Africa and the Critical Care Society of Southern Africa, where these are relevant to the care of trauma. The committee attempted to harmonise these criteria with the goals of the World Health Organization essential trauma care guidelines for trauma centres and trauma systems. Wide expert consultation was undertaken to refine the criteria before final compilation. RESULTS AND RECOMMENDATIONS: Four levels of trauma care facility are outlined, with the criteria focusing on the trauma-specific requirements of the facilities and their place in the greater trauma system. Accreditation of hospitals according to the criteria will allow for appropriate transfer and designation of patient destination for trauma patients and will improve the quality of care provided. The criteria address structural, process and human resource requirements and medical aspects for the accreditation of various level of trauma centre. CONCLUSION: There is a great opportunity to apply best practice criteria to improve the care of trauma in South Africa and improve patient outcome

The natural quinones lapachol, α-lapachone and β-lapachone, and the synthetic derivative β-lapachone-3-sulfonic-acid were assayed for inhibition of fungal growth (Fusarium oxysporum) and germination of lettuce seeds (Lactuca sativa L.). β-Lapachone has the strongest activity as a germination inhibitor and lapachol shows no effect. β-Lapachone, followed by lapachol, are the most active in reducing fungal growth.
