Abstract: The concept of systems biology emerged over the last decade in order to address advances in experimental techniques. It aims to characterize biological systems comprehensively as a complex network of interactions between the system's components.

Network biology has become a core research domain of systems biology. It uses a graph theoretic approach. Many advances in complex network theory have contributed to this approach, and it has led to practical applications spanning from disease elucidation to biotechnology during the last few years.

Herein we applied a network approach in order to model heterogeneous biological interactions. We developed a system called megNet for visualizing heterogeneous biological data, and showed its utility by biological network visualization examples, particularly in a biomedical context.

In addition, we developed a novel biological network analysis method called Enriched Molecular Path detection method EMPath that detects phenotypic specific molecular paths in an integrated molecular interaction network.

We showed its utility in the context of insulitis and autoimmune diabetes in the non-obese diabetic NOD mouse model. Specifically, ether phosholipid biosynthesis was down-regulated in early insulitis. As a result, ether lipids were diminished in the type 1 diabetes progressors. Also, in this thesis we performed topological calculations to investigate whether ubiquitous complex network properties are present in biological networks.

Results were consistent with recent critiques of the ubiquitous complex network properties describing the biological networks, which gave motivation to tailor another method called Topological Enrichment Analysis for Functional Subnetworks TEAFS. This method ranks topological activities of modules of an integrated biological network under a dynamic response to external stress.

We showed its utility by exposing an integrated yeast network to oxidative stress. Results showed that oxidative stress leads to accumulation of toxic lipids.

Graph Theory and Biological Networks

Objectives: This tutorial invited biologists, mathematicians and computer scientists to learn more about graph theory. Biologists learned how graph theory can inform their understanding of many common biological patterns that are in and of themselves graphs: pedigrees, fate maps, phylogenetic trees, metabolic pathways, food webs, epidemiological networks, interactomes, etc. Mathematicians and computer scientists learned how graph theoretical concepts such as interval graphs, planar graphs, trees, networks, Delaunay triangulations, Gabriel graphs, minimal spanning trees, etc. Participants applied what they learned in lectures to actual data in a computer laboratory context by using open source, open access tools and databases.

Advanced Technologies. The theory of complex networks plays an important role in a wide variety of disciplines, ranging from communications to molecular and population biology. The focus of this article is on graph theory methods for computational biology. We'll survey methods and approaches in graph theory, along with current applications in biomedical informatics. Within the fields of Biology and Medicine, potential applications of network analysis by using graph theory include identifying drug targets, determining the role of proteins or genes of unknown function. There are several biological domains where graph theory techniques are applied for knowledge extraction from data.

Metrics details. Understanding complex systems often requires a bottom-up analysis towards a systems biology approach. The need to investigate a system, not only as individual components but as a whole, emerges. This can be done by examining the elementary constituents individually and then how these are connected. The myriad components of a system and their interactions are best characterized as networks and they are mainly represented as graphs where thousands of nodes are connected with thousands of vertices. In this article we demonstrate approaches, models and methods from the graph theory universe and we discuss ways in which they can be used to reveal hidden properties and features of a network.

Graph theory and networks in Biology.

Eigenvector Centrality61 3. Likewise, graph theory is useful in biology and conservation efforts where a vertex can represent regions where certain species exist or inhabit and the edges represent migration paths or movement between the regions. Page Rank67 Chapter 6. History Graph theory is a branch of mathematics which studies the structure of graphs and networks. Application of Graphs: Computer Science: In computer science, graph is used to represent networks of communication, data organization, computational devices etc. Constitutional molecular graphs have points vertices representing atoms and lines edges symbolizing malent bonds. European Journal of Pharmaceutical Sciences , 24 ,

Networks are one of the most common ways to represent biological systems as complex sets of binary interactions or relations between different bioentities. In this article, we discuss the basic graph theory concepts and the various graph types, as well as the available data structures for storing and reading graphs. In addition, we describe several network properties and we highlight some of the widely used network topological features. We briefly mention the network patterns, motifs and models, and we further comment on the types of biological and biomedical networks along with their corresponding computer- and human-readable file formats. Finally, we discuss a variety of algorithms and metrics for network analyses regarding graph drawing, clustering, visualization, link prediction, perturbation, and network alignment as well as the current state-of-the-art tools.

Markov Chains and Random Walks64 4. Kruskal's Algorithm 1. In the field of microbiology, graph can express the molecular structure, where cell, gene or protein can be denoted as a vertex, and the connect element can be regarded as an edge. Many algorithms are used to solve problems that are modeled in the form of graphs… These things, are more formally referred to as vertices, vertexes or nodes, with the connections themselves referred to as edges.

 Я же сказал. Я прочитал все, что вы доверили компьютеру. - Это невозможно.

Беккер увидел в зеркале заднего вида разъяренное лицо, но словно оцепенел. Раздраженный водитель резко нажал на педаль тормоза, и Беккер почувствовал, как перемещается куда-то вес его тела. Он попробовал плюхнуться на заднее сиденье, но промахнулся. Тело его сначала оказалось в воздухе, а потом - на жестком полу. Из тени на авенида дель Сид появилась фигура человека.
