¿Cómo se mira un espacio de desaparición? ¿De qué manera fotografiar el lugar que ha visto por última vez un desaparecido? ¿Cómo contar los hechos de los que esas paredes han sido testigos? Y, finalmente, ¿cómo desandar ...
Differential efficiency of two strains of the arbuscular mycorrhizal fungus Rhizophagus irregularis on olive (Olea europaea) plants under two water regimes
(Springer, 2013-10)
The water regime affects a wide variety of physiological and biochemical processes in plants including an increased production of reactive oxygen species (ROS) capable of causing oxidative damage to proteins, DNA and lipids. ...
Solar UV-B radiation modulates chemical defenses against Anticarsia gemmatalis larvae in leaves of field-grown soybean
(Pergamon-Elsevier Science Ltd, 2017-09)
Although it is well known that solar ultraviolet B (UV-B) radiation enhances plant defenses, there is less knowledge about traits that define insect resistance in field-grown soybean. Here we study the effects of solar ...
Viability of probiotic (Bifidobacterium, Lactobacillus acidophilus and Lactobacillus casei) and nonprobiotic microflora in Argentinian Fresco cheese
(American Dairy Science Association, 2000-06)
We evaluated the suitability of Argentinian Fresco cheese as a food carrier of probiotic cultures. We used cultures of Bifidobacterium bifidum (two strains), Bifidobacterium longum (two strains), Bifidobacterium sp. (one ...
Seeking a fingerprint: analysis of point processes in actigraphy recording

Motor activity of humans displays complex temporal fluctuations which can be characterised by scale-invariant statistics, thus demonstrating that structure and fluctuations of such kinetics remain similar over a broad range ...
Natural terpenoids from Ambrosia species are active in vitro and in vivo against human pathogenic trypanosomatids
(Public Library Of Science, 2013-09)
Among the natural compounds, terpenoids play an important role in the drug discovery process for tropical diseases. The aim of the present work was to isolate antiprotozoal compounds from Ambrosia elatior and A. scabra. ...
Retinoic acid promotes apoptosis and differentiation in photoreceptors by activating the p38 MAP kinase pathway
(Association For Research In Vision And Ophthalmology, 2013-04)
Purpose Retinoic acid (RA) has a critical role during development of the retina, controlling cell fate and differentiation. We here investigated RA effects on photoreceptor differentiation and apoptosis and the intracellular ...
Extrafloral nectar fuels ant life in deserts
(Oxford University Press, 2014-11-07)
Interactions mediated by extrafloral nectary (EFN)-bearing plants that reward ants with a sweet liquid secretion are well documented in temperate and tropical habitats. However, their distribution and abundance in deserts ...
In vitro tuberization and plant regeneration from multinodal segment culture of Habenaria bractescens Lindl., an Argentinean wetland orchid
(Springer, 2009-01)
Tuberization in many terrestrial orchids represents the most important physiological process for reproduction and survival. An in vitro controlled and reproducible tuberization and plant regeneration system was designed ...
