A Potential Correlation Between the Temperature of the Pacific Ocean and Data from Google Trends May Yield a Warning Sign for the Outbreak of Zika
There has been a large number of reported cases of the occurrence of Zika in
different countries in 2016 and it is necessary to develop an early warning
system to initiate preventive campaigns against the disease. A potential early
warning system based on the rise in ocean temperature of the Pacific Ni\~no
Index is proposed. The efficacy is verified using data for the outbreak in
Colombia as obtained from Google Trends.Comment: 3 pages, 2 figures, Open Acces
A Preliminary Mathematical Model for the Dynamic Transmission of Dengue, Chikungunya and Zika
Aedes aegypti is a known vector of Dengue, Chikungunya and Zika and the goal
of this study is to propose the first mathematical model to describe the
dynamic transmission of these three diseases. We present two preliminary models
that consist of the SEIR model for the human populations and an SEI model for
the vector to describe (a) the single transmission dynamics of dengue,
Chikungunya or Zika, and (b) any possible coinfection between two diseases in
the same population. In order to do that, we obtain an analytical solution of
the system of 17 and 30 coupled differential equations for each model
respectively, and later obtain the eigenvalues by analyzing the Jacobian matrix
in order to begin the development of a surveillance system to prevent the
spread of these three diseases.Comment: 5 pages, 2 figures, open acces
Analysis of an SEIR-SEI four-strain epidemic dengue model with primary and secondary infections
We propose an SEIR model for the populations and an SEI model for the vector
to describe the transmission dynamics of a four-strain model with both primary
and secondary dengue infections. In order to accomplish this, we propose and
obtain an analytic solution of a system of 47 coupled differential equations.
This would be the most complete epidemic model proposed to describe the dengue
epidemic.Comment: 5 pages, 2 figures, 1 tabl
Can Bioinformatics Be Considered as an Experimental Biological Science?
The objective of this short report is to reconsider the subject of
bioinformatics as just being a tool of experimental biological science. To do
that, we introduce three examples to show how bioinformatics could be
considered as an experimental science. These examples show how the development
of theoretical biological models generates experimentally verifiable computer
hypotheses, which necessarily must be validated by experiments in vitro or in
vivo.Comment: 3 pages, Open Acces
Distributed computing applied applied to the identification of new drugs
This work emphasizes the assets of implementing the distributed computing for
the intensive use in computational science devoted to the search of new
medicines that could be applied in public healthy problems.Comment: 12 pages, Spanis
Phylogenetic tree calculations using the Grid with DAG job
The goal of the work is to implement molecular phylogenetic calculations
using the Grid paradigm by means of the MrBayes software using Directed Acyclic
Graphs (DAG) jobs. In this method, a set of jobs depends on the input or the
output of other jobs. Once the runs have been successfully done, all the
results can be collected by a specific Perl script inside the defined DAG job.
For testing this methodology, we calculate the evolution of papillomavirus with
121 sequences.Comment: 5 pages, 2 figure
Identification of 11 potential malaria vaccine candidates using Bioinformatics
In this paper, we suggested eleven protein targets to be used as possible
vaccines against Plasmodium falciparum causative agent of almost two to three
million deaths per year. A comprehensive analysis of protein target have been
selected from the small experimental fragment of antigen in the P. falciparum
genome, all of them common to the four stages of the parasite life cycle (i.e.,
sporozoites, merozoites, trophozoites and gametocytes). The potential vaccine
candidates should be analyzed in silico technique using various bioinformatics
tools. Finally, the possible protein target according to PlasmoDB gene ID are

Identificaci\'on de nuevos medicamentos a trav\'es de m\'etodos computacionales
Resumen: El desarrollo de nuevos medicamentos es un problema complejo que
carece de una soluci\'on \'unica y autom\'atica desde un punto de vista
computacional, debido a la carencia de programas que permitan manejar grandes
vol\'umenes de informaci\'on que est\'an distribuidos a lo largo de todo el
mundo entre m\'ultiples bases de datos. Por ello se describe una metodolog\'ia
que permita realizar experimentos in silico para la identificaci\'on actual de
nuevos medicamentos.
Abstract: The development of new drugs is a problem that nowadays has no
solution in terms of computational power due to the lack of software for
handling the big volume of available information; besides, these data are
stored in multiple formats and are distributed all around the world. To resolve
that, a development of an in silico drug design methodology.Comment: 20 pages, 4 figures, Spanish pape
Analyzing the love affair of Romeo and Juliet with modern mathematical tools
We facetiously suggest that the romance between Romeo and Juliet can be
interpreted using modern terminology and include current temptations. Using
this model, we consider various factors such as the time that they might spend
consulting social networks, the time that they could spend alone together and
along with friends as well as their tolerance of being able to waste the
couple's money. The model consists of a set of differential equations which
describes the relationship between them. Finally, we analyze the eigenvalues
the mathematical equations in order to determine if the critical point in this
model is stable or not in four different hypothetical scenarios.Comment: 4 pages, 0 figure
Challenges and characterization of a Biological system on Grid by means of the PhyloGrid application
In this work we present a new application that is being developed. PhyloGrid
is able to perform large-scale phylogenetic calculations as those that have
been made for estimating the phylogeny of all the sequences already stored in
the public NCBI database. The further analysis has been focused on checking the
origin of the HIV-1 disease by means of a huge number of sequences that sum up
to 2900 taxa. Such a study has been able to be done by the implementation of a
workflow in Taverna.Comment: 8 pages, 3 figures, appears in Proceedings of the First EELA-2
