Effects of roads on the behaviour of the largest South American artiodactyl (Lama guanicoe) in an Argentine reserve
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
Animals may divert time and energy in similar ways in the presence of predators, humans or landscape infrastructures. Roads have facilitated the economic and social development of human populations. Nevertheless their ...
3-Methylcrotonyl Coenzyme A (CoA) carboxylase complex is involved in the Xanthomonas citri subsp. Citri lifestyle during citrus infection
(Public Library of Science, 2018-06)
Citrus canker is a disease caused by the phytopathogen Xanthomonas citri subsp. citri (Xcc), bacterium which is unable to survive out of the host for extended periods of time. Once established inside the plant, the pathogen ...
Identification of a Novel Starch Synthase III from the Picoalgae Ostreococcus tauri
(Elsevier France-editions Scientifiques Medicales Elsevier, 2017-02)
Hydrosoluble glycogen is the major energy storage compound in bacteria, archaea, fungi, and animal cells. In contrast, photosynthetic eukaryotes have evolved to build a highly organized semicrystalline granule of starch. ...
Ballistic spin resonance in multisubband quantum wires
(American Physical Society, 2014-03-25)
Ballistic spin resonance was experimentally observed in a quasi-one-dimensional wire by Frolov et al. [Nature (London) 458, 868 (2009)]. The spin resonance was generated by a combination of an external static magnetic field ...
Metformin promotes autophagy in Echinococcus granulosus larval stage
(Elsevier Science, 2018-09)
Cystic echinococcosis is a neglected parasitic disease caused by the larval stage of Echinococcus granulosus for which an effective treatment is not yet available. Since autophagy constitutes a homeostatic mechanism during ...
QM–MM Ehrenfest dynamics from first principles: photodissociation of diazirine in aqueous solution
(Springer, 2018-09)
This article describes an implementation of Ehrenfest molecular dynamics based on TDDFT and Gaussian basis sets, optimized for hybrid QM–MM simulations in GPU. The present method makes use of the equations of motion proposed ...
Cell growth-dependent subcellular localization of p8
(Wiley-liss, Div John Wiley & Sons Inc, 2006-04)
p8 is a stress-induced protein, biochemically related to the architectural factor HMG-I/Y, overexpressed in many cancers and required for tumor expansion. The molecular mechanisms by which p8 may exert its effect in aspects ...
Identification of neuronal enhancers of the proopiomelanocortin gene by transgenic mouse analysis and phylogenetic footprinting
(American Society for Microbiology, 2005-04)
The proopiomelanocortin (POMC) gene is expressed in the pituitary and arcuate neurons of the hypothalamus. POMC arcuate neurons play a central role in the control of energy homeostasis, and rare loss-of-function mutations ...
The complexity of mitochondrial complex iv: An update of cytochrome c oxidase biogenesis in plants
(Molecular Diversity Preservation International, 2018-03)
Mitochondrial respiration is an energy producing process that involves the coordinated action of several protein complexes embedded in the inner membrane to finally produce ATP. Complex IV or Cytochrome c Oxidase (COX) is ...
Thermal stability of CopA, a polytopic membrane protein from the hyperthermophile Archaeoglobus fulgidus
(Elsevier Science Inc., 2008-03)
Despite recent progress in understanding membrane protein folding, little is known about the mechanisms stabilizing these proteins. Here we characterize the kinetic thermal stability of CopA, a thermophilic P(IB)-type ...
