(2012)Paralytic shellfish poisoning (PSP) toxins are a group of naturally occurring neurotoxic alkaloids produced among several genera of primarily freshwater cyanobacteria and marine dinoflagellates. Although saxitoxin (STX) ...

(Elsevier, 2013)A linear ODE system with bounded continuous coefficients is studied. Provided that the diagonal terms are ‘‘separated’’ and the off-diagonal terms satisfy a smallness threshold, we present some sufficient conditions for ...

(2005)The notion of metabolic closure is presented and analyzed in terms of Robert Rosen’s theory of (M,R) systems. Recent results concerning (M,R) systems are reviewed, specially those defining self-referential equations like ...
-
(2012-05)FtsZ is a major protein in bacterial cytokinesis that polymerizes into single filaments. A dimer has been proposed to be the nucleating species in FtsZ polymerization. To investigate the influence of the self-assembly of ...

(Springer, 2013)Pyridoxal 50-phosphate is the active form of vitamin B6 and its deficiency is directly related with several human disorders, which make human pyridoxal kinase (hPLK) an important pharmacologic target. In spite of this, ...
-
(Ecological Society of Australia, 2013)Broad-scale richness gradients are closely associated with temperature and water availability. However, historical and evolutionary processes have also contributed to shape current diversity patterns. In this paper we focus ...
-
(Elsevier, 2013)Carrot (Daucus carota) is a biannual plant that accumulates massive amounts of carotenoid pigments in the storage root. Although the root of carrot plants was white before domestication, intensive breeding generated the ...
-
(International Society for Neurochemistry, 2007)Brain-derived neurotrophic factor (BDNF) and its receptor TrkB are essential regulators of synaptic function in the adult CNS. A TrkB-mediated effect at excitatory synapses is enhancement of NMDA receptor (NMDA-R)-mediated ...
-
(American Chemical Society, 2013)A system in a spatially degenerate ground state responds in a qualitatively different way to positive and negative point charges. This means that the molecular electrostatic potential is ill-defined for degenerate ...

(2001)In this note we examine the population structure of Pinus radiata, exotic plant that is invading fragments of the Maulino Forest. We evaluate pine density, age, proportion of reproductive individuals across 8 forest ...
-
(2009)In nature, prey and predator species are embedded in complex networks of ecological interactions. As a consequence, organism level reactions such as predator-induced prey defenses will not only influence the dynamics of ...

(2003)The new quaternary selenophosphate phases AMP2Se6 (A ¼ Cu, Ag and M ¼ Bi, Sb) were synthesized by ceramic methods at 1023 K. These phases were characterized by powder X-ray diffraction (XRD), Fourier transform infrared ...

(1998)The gametogenesis of a 2-year-old coho salmon broodstock population cultured in a fish farm in southern Chile was studied. Gonadosomatic index (GSI), microscopic gonadal traits, and serum levels of estradiol-17b(E2), ...

(2001)Feeding by the aphid Sipha flava produces a reddish spot on mature leaves of Sorghum halepense. The present work is aimed at determining whether this plant response entails induced resistance against the aphid. Old and ...
