Influence of the signal to noise ratio for the estimation of Permutation Entropy
(Elsevier Science, 2020-09)
In this paper, the influence of signal to noise ratio in the estimation of Permutation Entropy was studied upon signals obtained by simulations of a chaoticdeterministic system. Then, using a bootstrap scheme, we applied ...
Biomolecular signal tracker with fast time response
(International Federation of Automatic Control, 2019-12-26)
Signal tracking and the related signal derivative estimation are key pieces in feedback control engineered systems. In this work we present a synthetic biomolecular circuit that performs signal tracking with high precision ...
Sky-wave over-the-horizon radar simulation tool
(Institution of Engineering and Technology, 2020-11-30)
This work deals with the entire process of target detection and ranging by a sky-wave over-the-horizon radar (OTHR) computational model simulation. The different processing stages of the transmitted signal along its ...
Repression of 5-aminolevulinate synthase gene by the potent tumor promoter, TPA, involves multiple signal transduction pathways
(Elsevier Science Inc, 2005-04)
The potent tumor promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA) induces activator protein-1 (AP-1) transcription factors, early response genes involved in a diverse set of transcriptional regulatory processes, and ...

Matrix Crosslinking Forces Tumor Progression by Enhancing Integrin Signaling
(Cell Press, 2009-11)
Tumors are characterized by extracellular matrix (ECM) remodeling and stiffening. The importance of ECM remodeling to cancer is appreciated; the relevance of stiffening is less clear. We found that breast tumorigenesis is ...
Role of the ERK1/2 signaling pathway in the replication of junín and tacaribe viruses
(MDPI, 2018-04)
We have previously shown that the infection of cell cultures with the arenaviruses Junín (JUNV), Tacaribe (TCRV), and Pichindé promotes the phosphorylation of mitogen-activated protein kinases (MAPKs) extracellular ...
Dissection of MAPK signaling specificity through protein engineering in a developmental context
(BioMed Central, 2018-04)
Background: Mitogen-activated protein kinases (MAPK) signaling affects many processes, some of which have different outcomes in the same cell. In Arabidopsis, activation of a MAPK cascade consisting of YODA, MKK4/5 and ...
