The performance of serologic tests in chronic Chagas disease diagnosis largely depends on the type and quality of the antigen preparations that are used for detection of anti-Trypanosoma cruzi antibodies.Whole-cell T.cruzi extracts or recombinant proteins have shown variation in the performance and cross-reactivity.Synthetic chimeric proteins compr
Vortex formation and dynamics of defects in active nematic shells
We present a hydrodynamic model for a thin spherical shell of active nematic liquid crystal with an arbitrary configuration of defects.The active flows generated by defects in the director lead to the formation of stable vortices, analogous to those seen in confined systems in flat geometries, which generate effective dynamics for four +1/2 defects
Globally Exponential Stability and Globally Power Stability of Quaternion-Valued Neural Networks With Discrete and Distributed Delays
This paper investigates the stability of a class of quaternion-valued neural networks (QVNNs) with discrete and distributed delays.By decomposing the QVNN and forming an equivalent real-valued vector-matrix differential equation (RVVDE), based on the Lyapunov theory and some matrix inequalities, some Lotions sufficient conditions are derived to ens
Reelin secreted by GABAergic neurons regulates glutamate receptor homeostasis.
BackgroundReelin is a large secreted protein of the extracellular matrix that has been proposed to participate to the etiology of schizophrenia.During development, reelin is crucial for the correct cytoarchitecture of laminated brain structures and is produced by a subset of neurons named Cajal-Retzius.After birth, most of these cells degenerate an
