Formation of dendrimer-guest complexes as a strategy to increase the solubility of a phenazine N, N′-dioxide derivative with antitumor activity
(Elsevier, 2019-04-23)Poly(amidoamine) and Poly(propylenimine) dendrimers with different generations and peripheral groups were studied as solubility enhancers and nanocarriers for 7-bromo-2-hydroxy-phenazine N5,N10-dioxide. This compound ... -
Fortalezas y limitantes de Bio∑TERM®, un programa para calcular tiempo térmico
(Asociación Argentina de Ecología, 2024-04)La temperatura es uno de los principales factores que determinan el crecimiento y el desarrollo de las plantas. Los modelos de simulación de crecimiento a partir de las temperaturas bases (Tb) y los requerimientos de ... -
Functional crop types are more important than diversity for the productivity, profit and risk of crop sequences in the inner Argentinean Pampas
(Elsevier, 2022-02)CONTEXT: Over the last 250 years, many natural ecosystems in South America, including the Inner Pampas of Argentina, evolved into extremely simplified agroecosystems. In the last 25 years, simplified soybean-based crop ... -
Further description of Helicoverpa zea (Lepidoptera: noctuidae) male genitalia and new genetic evidence of synonymy with respect to the anomalous form, “heliothis stombleri”
(2017-05-02)The Helicoverpa/Heliothis complex can cause serious damage to agricultural crops. Phenotypic similarity makes it difficult to discriminate between closely related Helicoverpa species. Currently, morphology of the male ... -
Fusarium graminearum species complex occurrence on soybean and F. graminearum sensu stricto inoculum maintenance on residues in soybean‐wheat rotation under field conditions
(Wiley, 2020-07)Aims: The aims of this study were to determine the occurrence of Fusarium graminearum species complex (FGSC) on soybean pods, seeds and roots, including rhizoplane, during the soybean crop in rotation with wheat and to ... -
Genetic structure of Argentinean hexaploid wheat germplasm
(2013-05)The identification of genetically homogeneous groups of individuals is an ancient issue in population genetics and in the case of crops like wheat, it can be valuable information for breeding programs, genetic mapping and ... -
Ground/satellite observations and atmospheric modeling of dust storms originating in the high Puna‐Altiplano deserts (South America): Implications for the interpretation of paleo‐climatic archives
(2013-05)This study provides a detailed description of the sources, transport, dispersion, and deposition of two major dust events originating from the high‐altitude subtropical Puna‐Altiplano Plateau (15–26°S; 65–69°W) in South ... -
Halo-hydromorphism alters nitrogen fertilization responses of tall wheatgrass pastures: Capture and use of resources, tiller dynamics and forage production
(Wiley, 2024-03)Halo-hydromorphism limits productivity in approximately 100 million hectares worldwide. Tall wheatgrass (Thinopyrum ponticum) is a species widely used in these environments for its seeding potential, being the addition of ... -
Histophilus somni myocarditis and leptomeningitis in feedlot cattle: case report and occurrence in South America
