Abstract: There is a large discrepancy between results of Crystal Barrel and WA102 for the branching ratio R = BR[eta2(1870)->a2(1320)pi]/ BR[eta2(1870)->f2(1270)eta]. An extensive re-analysis of the Crystal Barrel data redetermines branching ratios for decays of eta2(1870), eta2(1645), eta2(2030) and f2(1910). This re-analysis confirms a small value for R of 1.60+-0.39, inconsistent with the value 32.6+-12.6 of WA102. The likely origin of the discrepancy is that the WA102 data contain a strong f2(1910)->a2-pi signal as well as eta2(1870). There is strong evidence that the eta2(1870) has resonant phase variation. A peak in f2(1270)a0(980) confirms closely the parameters of the a2(2255) resonance observed previously. A peak in eta2(2030)-pi is interpreted naturally in terms of pi2(2245) with reduced errors for mass and width M=2285+-20(stat)+-25(syst) MeV, Gamma=250+-20(stat)+-25(syst) MeV.
Apuntes para una historia de la producción lexicográfica monolingüe en la Argentina: etapas del proceso de diccionarización y modalidades diccionarísticas entre 1870 y 1910 SOME NOTES ON THE HISTORY OF MONOLINGUAL LEXICOGRAPHIC PRODUCTION IN ARGENTINA: STAGES OF THE DICTIONARIZATION PROCESS AND LEXICOGRAPHIC MODALITIES BETWEEN 1870 AND 1910  [cached]

Abstract: En la Argentina, desde 1870 se inició una prolífica producción de instrumentos lexicográficos que registraban singularidades léxicas. La conciencia de tal peculiaridad condujo a confeccionar, continuando con la tradición hispanoamericana, diccionarios complementarios y contrastivos de diferentes modalidades. Por un lado, se publicaron obras descriptivas que recogían ruralismos, indigenismos, regionalismos (tanto americanismos como provincialismos o localismos) y argentinismos; por otro, algunas normativas que recolectaban barbarismos y censuraban su uso, tomando como parámetro la norma del castellano peninsular. Este artículo estudia las relaciones entre las distintas etapas del proceso de diccionarización y las diversas modalidades diccionarísticas. Para ello, analizamos los diccionarios que registran la variedad argentina del espa ol publicados entre 1870 y 1910, atendiendo a dos aspectos: a) las diferentes condiciones del proceso de diccionarización y b) ciertos recortes seleccionados de los diversos dominios que conforman el discurso lexicográfico (paratexto, macroestructura, microestructura). De esta manera, el trabajo se propone mostrar, en primer lugar, que el diccionario monolingüe es un instrumento discursivo, histórico e ideológico. En segundo lugar, el análisis del discurso lexicográfico permite observar que dichos diccionarios operan al servicio de la construcción del imaginario nacional en el marco del proceso de formación y consolidación del Estado nacional moderno. Since 1870, a prolific production of lexicographic instruments registering lexical singularities began in Argentina. The awareness of this peculiarity led to the elaboration -thus following a Hispanic American tradition- of complementary and contrastive dictionaries of different modalities. On the one hand, descriptive works were published that collected ruralisms, indigenisms, regionalisms (both Americanisms and provincialisms, or localisms), and Argentinianisms. On the other hand, some normative works emerged that collected barbarisms and censored their use, on account of their deviation from the peninsular Spanish variety. This paper studies the relations among the different stages of the dictionarization process and several dictionary-making modalities. To this effect, we analyze those dictionaries that included the Argentinian variety of the Spanish language, published between 1870 and 1910, by taking into account two aspects: a) the different conditions of the dictionarization process; and b) some cuts of segments selected from several domains of the lexicographical disco

La viruela: ha muerto?

Revista del Instituto Nacional de Higiene Rafael Rangel , 2007,
Abstract: La viruela ha desempe ado un papel sin paralelo en la historia de la humanidad y sigue siendo una amenaza potencial a la salud pública. A pesar de la significación histórica, aún es muy poco lo que sabemos de ella. Resulta difícil precisar el alcance de un brote de infección por el virus de la viruela como consecuencia de una liberación accidental o deliberada, pero mientras existan reservas del virus, el riesgo de liberación accidental no puede reducirse a cero. De abrirse la caja de Pandora, la humanidad estaría condenada a repetir la historia de ese flagelo, del cual no sabríamos predecir el comportamiento que tendría, ni su evolución. Deberíamos acelerar el momento en el que pongamos la viruela en los libros de historia, y no en el laboratorio. The smallpox has played a part without parallel in the humanity’s history and it continues being a potential threat to the public health. In spite of the historical significance, it is still very little what we know about her. It is difficult to specify the reach of an outbreak of the smallpox, like consequence of an accidental or deliberate liberation, but while reservations of the virus exist, the risk of accidental liberation cannot decrease to zero. Of opening up the pandora box, the humanity would be condemned to repeat the history of diseases, of which we would not know how to predict the behavior that would have, neither her evolution. We should accelerate the moment in which put the smallpox in the Books of History, and not in the Laboratory.

Abstract: An isoscalar resonance, X(1870), with a mass $M=1877.3\pm6.3(stat)^{+3.4}_{-7.4}(syst)$MeV and width $\Gamma=57\pm12(stat)^{+19}_{-4}(syst)$MeV was observed by the BesIII Collaboration recently. The mass of X(1870) is compatible with $\eta_2(1870)$ but the decay width is much smaller. In this paper, we analyzed the mass and the two-body strong decay of $\eta_2(1870)$ and X(1870). According to the mass spectra predicted by the Godfrey-Isgur potential model, X(1870) can be candidates of the states $f'_1(2^3P_1)$, $\eta'_2(1^1D_2)$ or $\eta_2(2^1D_2)$. In the Regge trajectories (RTs) framework, X(1870) favors the $\eta'(3^1S_0)$ and $f'_1(2^3P_1)$ assignments. However, the decay properties of $\eta'(3^1S_0)$, $f'_1(2^3P_1)$, $\eta'_2(1^1D_2)$ disagree with the experiments. The two-body strong decay widths indicate that $\eta_2(1870)$ and X(1870) maybe the two different resonant structures. $\eta_2(1870)$ could be assigned to the $\eta_2(2^1D_2)$ quarkonium as the first radical excited state of $\eta_2(1645)$. X(1870) favors a $\eta_H(0^+2^{-+})$ hybrid assignment. Some significant decay modes are suggested to test in future.

Abstract: El objetivo del presente trabajo es el estudio biológico y radioquímico de dos análogos de la somatostatina, el péptido RC-160 y el Tyr3-Octreotide (TOC), marcados con 99mTc por método directo e indirecto usando como quelantes mercapto acetil triglicina (MAG3) e hidrazinonicotinamida (HYNIC) respectivamente.Se realizó la síntesis del benzoil MAG3-RC-160 y del HYNIC-Tyr3-Octreotide los cuales se marcaron con 99mTc obteniéndose purezas radioquímicas mayor que 70% y mayor que 95% respectivamente.Se realizaron biodistribuciones en ratas Wistar normales y los resultados se correlacionaron con los datos cromatográficos y de unión a proteinas, encontrándose que a menor lipofilicidad de los complejos se incrementaba la excreción renal.Se realizaron ensayos de unión a receptores utilizando como fuente de los mismos membranas de corteza de cerebro de rata.Los mejores resultados se obtuvieron con el conjugado de HYNIC-TOC marcando con tricina como coligando. The aim of the present work was to study the biological and radiochemical behaviour of two somatostatin analogues, the RC-160 and Tyr3Octreotide(TOC) peptides when labeling with 99mTc by an indirect method using S-Benzoyl- mercaptoacetyl triglycine (MAG3) and hydrazinonicotinamide (HYNIC) as chelating agents. The synthesis of RC160 with S-Benzoyl MAG3 and TOC with HYNIC, for labeling with 99mTc are also described. The conjugates were prepared on a small scale and labeled with the radionuclide using tricine as coligands for HYNIC conjugates. Chromatohraphic studies were performed using an HPLC system and radiochemical purities higher than 75% and 95% were obtained respectively. Biodistributions studies in normal Wistar rats were performed and results were correlated with chromatographic and protein binding properties. Lower lipophilicity of the labeled conjugates resulted in a higher renal excretion. HYNIC-TOC complex showed promising results when labeling with 99mTc using tricine as coligand although higher stability should be found for ternary coligands compared to tricine.
