| Eighty-six newly diagnosed multiple myeloma (MM) patients from a public hospital of São Paulo (Brazil) were evaluated by cIg-FISH for the presence of del(13)(q14), t(4;14)(p16.3;q32) and del(17)(p13). These abnormalities were observed in 46.5, 9.3, and 7.0% of the patients, respectively. In order to identify the possible role of del(13)(q14) in the physiopathology of MM, we investigated the association between this abnormality and the proliferative and apoptotic indexes of plasma cells. When cases demonstrating t(4;14)(p16.3;q32) and del(17)(p13) were excluded from the analysis, we observed a trend towards a positive correlation between the proportion of cells carrying del(13)(q14) and plasma cell proliferation, determined by Ki-67 expression (r = 0.23, P... |

| Con el objetivo de integrar diferentes prácticas culturales en un sistema de control de malezas en maíz, se instaló un ensayo en el Campo Experimental de la Universidad Autónoma Chapingo (México) (2250 msnm, precipitación media anual 550 mm, suelo franco, 1.7% M.O.) bajo condiciones de secano, en donde se evaluaron dos densidades (44.400 y 66.600 pl/ha), dos distribuciones (normal y equidistante) y siete métodos de control de malezas (cyanazine + alachlor (1,2 + 1,92 kg/ha), atrazine + alachlor (1,2 + 1,44 kg/ha), un escarda, dos escardas, testigo siempre desmalezado, testigo siempre desmalezado + dos escardas y testigo siempre enmalezado). Las principales malezas presentes fueron: quelite (Amaranthus sp.), perlilla (Lopezia mexicana Jacq.), rosilla chita... |
