Autoantibodies against Cajal bodies in systemic lupus erythematosus
(International Scientific Information, 2004-05-01)Cajal bodies (CB) are distinct sub-nuclear domains rich in small nuclear ribonucleoprotein particles (snRNPs); they are involved in pre-mRNA processing. Lupus erythematosus (SLE) is an autoimmune disease characterized ... -
Abiotic stress response in plants: integrative genetic pathways and overlapping reactions between abiotic and biotic stress responses
(Nova Science Publishers, Inc, 2012-01)In all ecosystems, plants continuously face environmental stress and consequently are forced to respond with defensive and adaptive strategies. These responses require the activation of several signaling pathways that ... -
Abiotic Stress in Plants and Metabolic Responses
(INTECH, 2013-03-13)The vast metabolic diversity observed in plants is the direct result of continuous evolutionary processes. There are more than 200,000 known plant secondary metabolites, representing a vast reservoir of diverse functions. ... -
Low-dimensional thermoelectricity in graphene: The case of gated graphene superlattices
(Elsevier, 2018-07)Low-dimensional thermoelectricity is a key concept in modern thermoelectricity. This concept refers to the possibility to improve thermoelectric performance through redistribution of the density of states by reducing the ... -
Controlling the optical absorption properties of d-FETs by means of contact voltage and hydrostatic pressure effects
(Elsevier, 2017-12)The effects of contact voltage and hydrostatic pressure on subband structure and optical transitions in GaAs delta-Field Effect Transistor (d-FET) are theoretically studied. The electronic structure of d-FET under ... -
Self-similar transmission patterns induced by magnetic field effects in graphene
(Elsevier, 2018-07)In this work we study the propagation of Dirac electrons through Cantor-like structures in graphene. In concrete, we are considering structures with magnetic and electrostatic barriers arrange in Cantor-like fashion. The ... -

(Elsevier, 2018-03)It is reported a numerical computation of the local density of states for a d-doped like QW superlattices of AlxGa1 xAs, as a possible heterostructure that, being integrated into a solar cell device design, can provide ... -
Asymmetrical external effects on transmission, conductance and giant tunneling magnetoresistance in silicene
(Elsevier, 2018-01)Electron transport in a silicene structure, composed of a pair of magnetic gates, is studied in a ferromagnetic and antiferromagnetic configuration. The transport properties are investigated for asymmetrical external ... -
Fano resonances in bilayer graphene superlattices
(Springer Nature, 2017-12-01)In this work, we address the ubiquitous phenomenon of Fano resonances in bilayer graphene. We consider that this phenomenon is as exotic as other phenomena in graphene because it can arise without an external extended ... -
Energy minibands degeneration induced by magnetic fieldeffects in graphene superlattices
(Elsevier, 2017-12)Energy minibands are a basic feature of practically any superlattice. In this regard graphene superlattices are not the exception and recently miniband transport has been reported through magneto-transport measurements. ... -
