Therapeutic drug
monitoring (TDM) has consistently been shown to be useful for optimization of
drug therapy. For the first time, a method has been developed for the text
analysis of TDM in SPCs in that a catalogue SPC-ContentTDM (SPCCTDM) provides a
codification of the content of TDM in SPCs. It consists of six structure-related
items (dose, adverse drug reactions, drug interactions, overdose,
pregnancy/breast feeding, and pharmacokinetics) according to implicit or
explicit references to TDM in paragraphs of the SPC, and four theory-guided
items according to the information about ranges of plasma concentrations and a
recommendation of TDM in the SPC. The catalogue is regarded as valid for the
text analysis of SPCs with respect to TDM. It can be used in the comparison of
SPCs, in the comparison with medico-scientific evidence and for the estimation
of the perception of TDM in SPCs by the reader. Regarding the approach as a
model of text mining, it may be extended for evaluation of other aspects
reported in SPCs.

Clustering of gene
expression data is a standard exploratory technique used to identify closely
related genes. Many other sources of data are also likely to be of great
assistance in the analysis of gene expression data. This data provides a mean to
begin elucidating the large-scale modular organization of the cell. The authors
consider the challenging task of developing exploratory analytical techniques to
deal with multiple complete and incomplete information sources. The Multi-Source
Clustering (MSC) algorithm developed performs clustering with multiple, but
complete, sources of data. To deal with incomplete data sources, the authors
adopted the MPCK-means clustering algorithms to perform exploratory analysis on
one complete source and other potentially incomplete sources provided in the
form of constraints. This paper presents a new clustering algorithm MSC to
perform exploratory analysis using two or more diverse but complete data
sources, studies the effectiveness of constraints sets and robustness of the
constrained clustering algorithm using multiple sources of incomplete biological
data, and incorporates such incomplete data into constrained clustering
algorithm in form of constraints sets.

3. PAPER
THREE :Infer
Species Phylogenies Using Self-Organizing Maps
With rapid
advances in genomics, phylogenetics has turned to phylogenomics due to the
availability of large amounts of sequence and genome data. However, incongruence
between species trees and gene trees remains a challenge in molecular
phylogenetics for its biological and algorithmic complexities. A
state-of-the-art gene concatenation approach was proposed to resolve this
problem by inferring the species phylogeny using a random combination of widely
distributed orthologous genes screened from genomes. However, such an approach
may not be a robust solution to this problem because it ignores the fact that
some genes are more informative than others in species inference. This paper
presents a self-organizing map (SOM) based phylogeny inference method to
overcome its weakness. The author’s proposed algorithm not only demonstrates its
superiority to the original gene concatenation method by using same datasets,
but also shows its advantages in generalization. This paper illustrates that
data missing may not play a negative role in phylogeny inferring. This study
presents a method to cluster multispecies genes, estimate multispecies gene
entropy and visualize the species patterns through the self-organizing map
mining.

FOUR :
Wave-SOM: A Novel
Wavelet-Based Clustering Algorithm for Analysis of Gene Expression
Patterns

University of Minnesota, USA
David McNabb, University of Arkansas,
USA
Eitan Gross, University of Arkansas, USA
In this paper, the
authors present a wavelet-based algorithm (Wave-SOM) to help visualize and
cluster oscillatory time-series data in two-dimensional gene expression
micro-arrays. Using various wavelet transformations, raw data are first
de-noised by decomposing the time-series into low and high frequency wavelet
coefficients. Following thresholding, the coefficients are fed as an input
vector into a two-dimensional Self-Organizing-Map clustering algorithm.
Transformed data are then clustered by minimizing the Euclidean (L2) distance
between their corresponding fluctuation patterns. A multi-resolution analysis by
Wave-SOM of expression data from the yeast Saccharomyces cerevisiae, exposed to
oxidative stress and glucose-limited growth, identified 29 genes with correlated
expression patterns that were mapped into 5 different nodes. The ordered
clustering of yeast genes by Wave-SOM illustrates that the same set of genes
(encoding ribosomal proteins) can be regulated by two different environmental
stresses, oxidative stress and starvation. The algorithm provides heuristic
information regarding the similarity of different genes. Using previously
studied expression patterns of yeast cell-cycle and functional genes as test
data sets, the authors’ algorithm outperformed five other competing
programs.

CALL FOR
PAPERS
1.
The mission of the
International Journal of Knowledge Discovery in Bioinformatics (IJKDB) is
to increase awareness of interesting and challenging biomedical problems and to
inspire new knowledge discovery solutions, which can be translated into further
biological and clinical studies. IJKDB is aimed at researchers in the areas of
bioinformatics, knowledge discovery, machine learning, and data structure, as
well as practitioners in the life sciences industry. In addition to original
research papers in bioinformatics, this journal emphasizes software and tools
that exploit the knowledge discovery techniques to address biological problems
and databases that contain useful biomedical data generated in wet and dry labs.
IJKDB encompasses discovery notes that report newly found biological discoveries
using computational techniques and includes reviews and tutorials on relevant
computational and experimental techniques for translational research and
knowledge discovery in life sciences.
