Este trabajo es fruto de las lecturas interdisciplinarias del relato de viaje de Hermann Burmeister Viaje por los Estados del Plata" (1861) llevadas a cabo por el subproyecto "iterología mendocina" incluido en el Proyecto Argentino de Literatura Comparada. Los pasajes seleccionados ilustran significativamente la relevancia literaria, histórica y geográfica de la obra. Se trata de los capítulos VIII y IX del mismo, que abarcan el informe del viajero en diligencia desde Río Cuarto (provincia de Córdoba) hasta la descripción de los alrededores de la ciudad de Mendoza a su arribo en marzo de 1857. La particularidad metodológica de cada disciplina se ha preservado con el objetivo común de revelar los múltiples objetivos científicos del autor. Desde el punto de vista de la Literatura Comparada a mi cargo he puesto de relieve la poética del discurso iterológico de Burmeister que a su vez conduce a la valoración intrínsecamente comparatista de historia y geografía, en la configuración poética de la montaña o del estereotipo de /a ciudad de Mendoza como paraíso.

This paper reports on the survey of the characteristic features of national input-output tables compiled by the member countries of the Asian International Input-Output Table project. In making any inter-regional tables, the presentation format of each constituent table has to be carefully studied in order to design a common adjustment rule. The survey was conducted in the period of 2003-04, with invaluable cooperation from each collaborating institution of the project. Some analytical findings are drawn from the survey results, such as the similarity between each national table and the Japanese table, the responsiveness to the 1993 SNA, and the major areas of conflict regarding the presentation format.

It was previously shown that coexpression of the lactose permease of Escherichia coli in two contiguous fragments leads to functional complementation. We demonstrate here that site-directed thiol crosslinking of coexpressed permease fragments can be used to determine helix proximity in situ without the necessity of purifying the permease. After coexpression of the six N-terminal (N6) and six C-terminal (C6) transmembrane helices, each with a single Cys residue, crosslinking was carried out in native membranes and assessed by the mobility of anti-C-terminal-reactive polypeptides on immunoblots. A Cys residue at position 242 or 245 (helix VII) forms a disulfide with a Cys residue at either position 28 or 29 (helix I), but not with a Cys residue at position 27, which is on the opposite face of helix I, thereby indicating that the face of helix I containing Pro-28 and Phe-29 is close to helix VII. Similarly, a Cys residue at position 242 or 245 (helix VII) forms a disulfide with a Cys residue at either position 52 or 53 (helix II), but not with a Cys residue at position 54. Furthermore, low-efficiency crosslinking is observed between a Cys residue at position 52 or 53 and a Cys residue at position 361 (helix XI). The results indicate that helix VII lies in close proximity to both helices I and II and that helix II is also close to helix XI. The method should be applicable to a number of different polytopic membrane proteins.

The major hurdle to be cleared in active immunotherapy of cancer is the poor immunogenicity of cancer cells. In previous attempts to overcome this problem, whole tumor cells have been used as vaccines, either admixed with adjuvant(s) or genetically engineered to express nonself proteins or immunomodulatory factors before application. We have developed a novel approach to generate an immunogeneic, highly effective vaccine: major histocompatibility complex (MHC) class I-positive cancer cells are administered together with MHC class I-matched peptide ligands of foreign, nonself origin, generated by a procedure we term transloading. Murine tumor lines of the H2-Kd or the H2-Db haplotype, melanoma M-3 and B16-F10, respectively, as well as colon carcinoma CT-26 (H2-Kd), were transloaded with MHC-matched influenza virus-derived peptides and applied as irradiated vaccines. Mice bearing a deposit of live M-3 melanoma cells were efficiently cured by this treatment. In the CT-26 colon carcinoma and the B16-F10 melanoma, high efficacies were obtained against tumor challenge, suggesting the universal applicability of this new type of vaccine. With foreign peptide ligands adapted to the requirements of a desired MHC class I haplotype, this concept may be used for the treatment of human cancers.
