Synthesis, X-Ray Structure, Tautomerism Aspect, and Chemical Insight of The 3-(1H-Indol-2-yl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-6-ol
2021
The 3-(1H-indol-2-yl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-6-ol 2 was obtained exclusively in the enol configuration starting from triazolyl-indole derivative 1 and alkyl halo-esters in the presence of K2CO3. Chemical structure elucidations with the aid of physicochemical characterizations were used to predict its molecular structure while single crystal X-ray diffraction technique was used to shed the light on the supramolecular structure of 2. DFT calculations agreed very well with the reported X-ray structure where the most stable form thermodynamically is the enol form. Its optimized geometry agreed very well with the experimental structure where the correlation coefficients betwe…

Organocatalytic Enantioselective Vinylogous Henry Reaction of 3,5-Dimethyl-4-nitroisoxazole with Trifluoromethyl Ketones
2017
The enantioselective vinylogous Henry reaction of 3,5-dimethyl-4-nitroisoxazole with trifluoromethyl ketones employing a bifunctional squaramide organocatalyst has been developed. A series of isoxazole bearing trifluoromethyl-substituted tertiary alcohols, 2-substituted (R)-1,1,1-trifluoro-3-(3-methyl-4-nitroisoxazol-5-yl)propan-2-ols, were obtained under these mild reaction conditions in good yields and moderate to good enantioselectivities

Acid–base properties of functionalised tripodal polyamines and their interaction with nucleotides and nucleic acids
2010
Novel, highly positively charged tripodal polyamines with appended heterocyclic moieties revealed an intriguing panel of protonation species within the biologically relevant range. Studied compounds bind nucleotide monophosphates by mostly electrostatic interactions but only the imidazole analogue showed selectivity toward UMP in respect to other nucleotides. Strong binding of all the studied compounds to both ds-DNA and ds-RNA is to some extent selective toward the latter, showing rather rare RNA over DNA preference.

Land surface temperature and evapotranspiration estimation in the Amazon evergreen forests using remote sensing data
2019
Amazonian tropical forests play a significant role in global water, carbon and energy cycles. Considering the relevance of this biome and the climate change projections which predict a hotter and drier climate for the region, the monitoring of the vegetation status of these forests becomes of significant importance. In this context, vegetation temperature and evapotranspiration (ET) can be considered as key variables. Vegetation temperature is directly linked with plant physiology. In addition, some studies have shown the existing relationship between this variable and the CO2 absorption capacity and biomass loss of these forests. Evapotranspiration resulting from the combined processes of …
Tumores intracraneles pediátricos: efectos tardíos de la enfermedad y sus tratamientos.
2014
Se describen los efectos tardíos provocados por la enfermedad y los tratamientos en los niños con tumores intracraneales. La mayoría pueden ser atribuidos al daño neurológico producido por el tumor y su extirpación, por la toxicidad de la quimioterapia y por los efectos de la radiación en el desarrollo del sistema nervioso central. Los efectos tardíos abarcan múltiples aspectos: médicos, neurocognitivos/educativos y sociales/comportamentales. Los pacientes presentan dificultades de aprendizaje, trastornos motrices y sensoriales, descensos de coeficiente intelectual, déficits en los procesos cognitivos básicos, problemas en el ajuste social, comportamental y emocional, y falta de competencia…
El impacto de la inmunosupresión precoz en las complicaciones no asociadas al injerto hepático
2018
La falta de mejora a largo plazo de los resultados post-TH se debe en gran medida a complicaciones no asociadas al injerto en principio muy relacionadas con la exposición crónica a IS. En diferentes estudios se ha demostrado como la minimización de los ICN tiene un efecto protector en términos de toxicidad renal, metabólica, cardíaca y oncogénica. Sin embargo, no existe una evidencia sólida sobre el impacto que pueda tener la IS precoz, es decir aquella administrada en el post-trasplante inicial, y el desarrollo de dichas complicaciones. El grupo de Rodríguez-Perálvarez ha demostrado que tanto los niveles de Tac mayores de 10 ng/mL durante los primeros 15 días post-TH como la presencia de p…
Co-Evolutionary Coupling Between Captured and Uncaptured GDP Cycles : Cross Learning from Amazon and Finland Models for Sustainability
2019
A solution to the critical problem of a dilemma between R&D expansion and productivity decline that a majority of information and communication technology (ICT) leaders have been confronting in the digital economy is expected. It can be expected by a spinoff from economic functionality-seeking GDP-based coevolution cycle to supra-functionality beyond an economic value-seeking uncaptured GDP-driven coevolution cycle. However, the transformation dynamism remains a black box. By means of numerical simulations based on empirical analyses of the development trajectories of global ICT leaders, focusing on Amazon and Finland, together with an intensive review of preceding analyses, this paper atte…
