Spinal cord injury induces astroglial conversion towards neuronal lineage
(Biomed Central, 2016-10-06)
Background: Neurons have intrinsic capability to regenerate after lesion, though not spontaneously. Spinal cord injury (SCI) causes permanent neurological impairments partly due to formation of a glial scar that is composed ...

Mechatronic modeling of a parallel kinematics multi-axial simulation table based on decoupling the actuators and manipulator dynamics
(Elsevier, 2016-11-07)
In this work a mechatronic model was developed for a parallel Multi-Axial Simulation Table (MAST) mechanism. The dynamics of the mechanism was obtained using the principle of energy equivalence and Boltzmann–Hamel equations. ...
Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
Glycosaminoglycans in human retinoblastoma cells: heparan sulfate, a modulator of the pigment epithelium-derived factor-receptor interactions
(BioMed Central, 2003-02-19)
BACKGROUND: Pigment epithelium-derived factor (PEDF) has binding affinity for cell-surface receptors in retinoblastoma cells and for glycosaminoglycans. We investigated the effects of glycosaminoglycans on PEDF-receptor ...
Quantum cosmology of the Big Rip: Within GR and in a modified theory of gravity
(MDPI, 2017-04-14)
Quantum gravity is the theory that is expected to successfully describe systems that are under strong gravitational effects while at the same time being of an extreme quantum nature. When this principle is applied to the ...
Cubiertas vegetales en un viñedo de Rioja Alavesa:influencia sobre el estado hídrico, crecimiento vegetativo, producción y calidad
(2017-07-05)
La erosión es la principal causa de la degradación de suelos en los viñedos bajo clima mediterráneo. Para su mitigación, una herramienta útil son las cubiertas vegetales sembradas o espontáneas en las calles del viñedo. ...
La estrategia defensiva del imperio en tiempos de Felipe III.
(2017-09-15)
La bibliografía acerca del reinado de Felipe III es abundante, aunque comparativamente menor que la que trata los periodos precedente y posterior . Está en gran medida lastrada por viejos tópicos que enturbian y dificultan ...
Regulation of Nociceptive Plasticity Threshold and DARPP-32 Phosphorylation in Spinal Dorsal Horn Neurons by Convergent Dopamine and Glutamate Inputs
(Public Library Science, 2016-09-09)
Dopamine can influence NMDA receptor function and regulate glutamate-triggered long-term changes in synaptic strength in several regions of the CNS. In spinal cord, regulation of the threshold of synaptic plasticity may ...
Association of Birth Order with Cardiovascular Disease Risk Factors in Young Adulthood: A Study of One Million Swedish Men
(Public Library of Science, 2013-05-16)
Background: Birth order has been suggested to be linked to several cardiovascular disease (CVD) risk factors, but the evidence is still inconsistent. We aim to determine the associations of birth order with body mass index ...
