Genomics, Proteomics – Bioinformatics

Benefits

We assess the ACT Model leads to each period. Additionally , for more integrated analysis, we execute a time series analysis among the top-ranked keyword phrases, journals, and authors according to their regularity. We likewise examine the patterns inside the top journals by simultaneously identifying the topical likelihood in each period, plus the top experts and search terms. The benefits indicate that in recent years varied topics have grown to be more prevalent and convergent matters have become more clearly represented.

Methods

With this paper, we adopt the Tang ain al. ‘s Author-Conference-Topic (ACT) model to analyze the field of bioinformatics from the perspective of keyword phrases, authors, and journals. The ACT style is capable of incorporating the paper, publisher, and conference into the matter distribution at the same time. To obtain more meaningful results, all of us use periodicals and keyword phrases instead of conventions and bag-of-words.. For examination, we employ PubMed to collected forty-six bioinformatics magazines from the MEDLINE database. All of us conducted period series subject analysis more than four times from 1996 to 2015 to further examine the interdisciplinary nature of bioinformatics.

Sequence analysis

Because the Phage Φ-X174 was sequenced in 1977, the DNA sequences of 1000s of organisms have already been decoded and stored in directories. This sequence information is usually analyzed to determine genes that encode aminoacids, RNA genes, regulatory sequences, structural occasion, and repeated sequences. An evaluation of genes within a varieties or between different kinds can show similarities between proteins functions, or perhaps relations among species (the use of molecular systematics to construct phylogenetic trees). With the growing amount of information, it long ago became impractical to analyze DNA sequences by hand. Today [the moment?] , computer programs such as BLAST are used daily to search sequences from more than 260 000 organisms, containing over 190 billion nucleot >These programs can compensate for mutations (exchanged, deleted or inserted bases) in the DNA sequence, to identify sequences that are related, but not identical. A variant of this sequence alignment is used in the sequencing process itself. For the special task of taxonomic classification of sequence snippets, modern k-mer based software like Kraken achieves throughput unreachable by alignment methods.

2.4.3.4.1 Using Bioinformatics

Bioinformatic techniques available online can be used to determine the fungal species based on the sequence result. The DNA sequence can be run in the NCBI BLAST program for alignment with highly similar sequences.

Most databases accept sequences in the FASTA format. This is a text-based format for representing nucleotide sequences using single-letter codes representing each of the four nucleotide bases. The format also allows for sequence names and comments to precede the sequences. A sequence in FASTA format begins with a single-line description, followed by lines of sequence data. The description line is distinguished from the sequence data by a greater-than (>) sign in the 1st column. It is recommended that all lines of text message be shorter than 80 characters in length. An example sequence looks like this:

TTTTTGTGAG TGATCTGATC CAGAATTGAA GTTTGTGGAT GTGTGGAACA TTTTAGGCTG

ACGGAATCTC TTCTGATCGA CAGGACAAGG ATGGCGATGG TGAGTGCGAT CTTTGCTGAA

To run BOOST, a user initial needs to enter the DNA pattern to be analyzed in the series data entrance box. The program has options to locate through the individual & mouse genome and others (the program to look through additional species with avoiding virtually any matches higher than 95% similarity with mouse and human). After that select megablast and click on the BLAST button. Couple of seconds later, a screen will appear with the graphical summary of sequences that align well. The display provides results having crescendo number and score of specific gene sequences. The accession amount can be clicked on for information on that specific sequence (see Table 2 . 4 ). The collection data in Table installment payments on your 4 stand for only the Cmd gene fromP. chrysogenum.

1.2 What is Bioinformatics

Bioinformatics is a multi-disciplinary field at the intersection of Biology, Computer Science, and Statistics. Naturally, its development has followed the technological advances and research trends in Biology and Information Technologies. Thus, although it is still a young field, it is evolving fast and its scope has been successively redefined. For instance, the National Institute of Health (NIH) defines Bioinformatics in a broad way, as the research, development, or application of computational tools and approaches for expanding the use of biological, medical, biological, behavioral, or health data . According to this definition, the tasks involved include data acquisition, storage, archival, analysis, and visualization.

Some authors have a more focused definition, which relates Bioinformatics mainly to the study of macromolecules at the cellular level, and emphasize its capability of handling large-scale data . Indeed, since its appearance, the main tasks of Bioinformatics have been related to handling data at a cellular level, and this will also be the focus of this book.

Still in the previous seminal document from the NIH, the related field of Computational Biology is defined as the development and application of data-analytical and theoretical methods, mathematical modeling, and computational simulation techniques to the study of biological, behavioral, and social systems. Thus, although deeply related, and sometimes used interchangeably by some authors, the first (Bioinformatics) relates to a more technologically oriented view, while the second is more related to the study of natural systems and their modeling. This does not prevent a large overlap of the two fields.

Bioinformatics tackles a large number of research problems. For instance, theBioinformatics( https://academic.oup.com/bioinformatics ) journal publishes research on application areas that include genome analysis, phylogenetics, genetic, and population analysis, gene expression, structural biology, text mining, image analysis, and ontologies and databases.

The National Center for Biotechnology Information (NCBI, https://www.ncbi.nlm.nih.gov/Class/MLACourse/Modules/MolBioReview/bioinformatics.html ) unfolds Bioinformatics into three main areas:

developing new algorithms and statistics to assess relationships within large data sets;

analyzing and interpreting different types of data (e.g. nucleotide and amino acid sequences, protein domains, and protein structures);

developing and implementing tools that enable efficient access and management of different types of information.

This book will focus mainly on the first of these areas, covering the main algorithms that have been proposed to address Bioinformatics tasks. The emphasis will be put on algorithms for sequence processing and analysis, considering both nucleotide and amino acid sequences.

Comparative genomics

The core of comparative genome analysis is the establishment of the correspondence between genes (orthology analysis) or other genomic features in different organisms. It is these intergenomic maps that make it possible to trace the evolutionary processes responsible for the divergence of two genomes. A multitude of evolutionary events acting at various organizational levels shape genome evolution. At the lowest level, point mutations affect indiv >Ultimately, whole genomes are involved in processes of hybridization, polyploidization and endosymbiosis, often leading to rapid speciation. The complexity of genome evolution poses many exciting challenges to developers of mathematical models and algorithms, who have recourse to a spectrum of algorithmic, statistical and mathematical techniques, ranging from exact, heuristics, fixed parameter and approximation algorithms for problems based on parsimony models to Markov chain Monte Carlo algorithms for Bayesian analysis of problems based on probabilistic models.

Many of these studies are based on the detection of sequence homology to assign sequences to protein families.

17.2 Journals and Conferences

Bioinformatics is a multidisciplinary area, and thus many of the important papers on Bioinformatics tools are spread along journals and conferences of different topics, from computer science to specific biological and biomedical venues. Still, there are a few important journals mainly devoted to this field, or that have specific tracks for Bioinformatics work.

The following list provides an overview of some selected journals and their publishers, and a brief description of their contents:

Bioinformatics(Oxford University Press) – probably the most important journal for this area, focuses mainly on new developments in genome bioinformatics and computational biology. Two sections – Discovery Notes and Application Notes – focus on shorter papers reporting biologically interesting discoveries using computational methods, and the development of bioinformatics applications.

Nucleic Acids Research(Oxford University Press) – its focus are physical, chemical, biochemical and biological aspects of nucleic acids and proteins involved in nucleic acid metabolism and/or interactions; although not a specific Bioinformatics journal, it is known for publishing yearly comprehensive reviews of available databases and web applications in all fields of Bioinformatics; even in the regular issues it publishes many articles on software applications to biological problems.

Briefings in Bioinformatics(Oxford University Press) – it is an international forum for researchers and educators in the life sciences, publishing reviews of databases and tools of genetics, molecular, and systems biology providing practical guidance in Bioinformatics approaches.

2 Related Work

Several studies have demonstrated the use of topic modeling to analyze scientific literature. Paul and Girju conducted analysis of literature in Computational Linguistics, and Education . Their work shows how topics change over time in each field and how topics across fields are related. Similarly, Bolelli and Gilesb analyzed publications to >7 ]. In a recent study, Kane et al. used topic models to compare the development of research on crops such as wheat, rice, sorghum, etc. . Results from the topic models revealed interesting trends on how research on perennial crops was advancing and that is different from the progress on individual crops.

Much closer to our work is Altena et al.’s study on understanding the term big data from a text analysis of bio-medical literature . While there are similarities in the literature corpus and techniques being applied, Altena et al.’s work differs from this study in that they restrict their study to big data literature in the bio-medical field while we analyze all areas of bioinformatics literature. In addition, we aim to search for over-arching patterns and trends in bioinformatics rather than focusing on one particular concept such as big data. Lastly, Suominen et al. performed topic modeling using LDA on scientific literature from Web of Science to compare how latent topics >23 ] and toxicogenomics data analysis . There is a notable not enough topic building based text message analysis aimed at the extensive corpus of bioinformatics literature to identify salient research subject areas and their advancement over time. Each of our work right here aims to load this gap.

4. 1 Keyword-Based Examination

We located 100, 754 unique keywords across the eighty five, 106 journals spanning around 18 years with an average of about several keywords every publication. The trend in the circulation of unique keywords in publications per year (Fig. two ) is very similar to the syndication of yearly publication quantities.

The brown cluster concentrates on computational tactics such as data mining, equipment learning, characteristic selection for drug style and breakthrough, protein-structure conjecture, pattern reputation, structural bioinformatics, etc . Moving on to the lilac cluster, we see data integration, database, semantic web, and ontologies being used for the study of phenotypes, progression, and phylogenies. This bunch points to the increasing applying ontologies and data incorporation for study regarding evolutionary phenotypes . The gray cluster is essentially related to proteomics, systems biology, functional genomics, analysis of microrna etc . The purple cluster is related to next generation sequencing, gene appearance analyses, genomics, transcriptome, and genetics.

Bibilometric analysis

Bibliometric analysis identifies the research styles in a provided subject area and core publications or files, and helps with contrastive analysis. Many bibliometric studies make use of the number of printed articles or perhaps journal effect factors to measure exploration productivity in order to identify key journals in a specific field. Soteriades and Falalgas applied quantitative and qualitative measurements to assess the areas of preventive medicine, work-related and environmental medicine, epidemiology and public health using the volume of articles and impact factor. Ugolini ain al. measured analysis productivity and evaluated the publication developments in the field of malignancy molecular epidemiology. To quantify productivity, they used the number of articles and average and sum of impact factors. To evaluate syndication trends, they collected and divided the keywords from MeSH conditions about the publication into six organizations. Ramos ainsi que al. measured the national analysis activity of the tuberculosis field, using influence factor and the first author’s address. Claude et approach. examined research productivity by using circulation of journals related to medicine and ANN, the subfield of biology. They applied the number of magazines, impact aspect, and diary category in comparison with national major domestic merchandise (GDP). In the bioinformatics field, Patra and Mishra used the amount of articles, newsletter of each diary, publication type, and the influence factor of journals to understand the growth of bioinformatics. In addition they found the core journals in the bioinformatics fields. Using author connection, they used Lotka’s regulation to assess the distribution of each and every author’s production. Chen ainsi que al. identified exploration trends using statistical methods based on the type of publication, terminology, and division of region or company. They assessed h-index, adding statistical materials with the quantity of citations. Through this, they will analyzed the research productivity by topic, establishment, and diary. In addition , that they conducted a keyword examination to comprehend the study trend in a macroscopic view.

Mainstream bibliometrics research concentrates on identifying the knowledge structure of a certain field with quantitative actions. In addition , a lot of studies work with author data or the collaboration pattern between authors to know the selected field. Seglen and Aksnes employed the size and the productivity of research groups in the microbiology field in Norway being a measurement intended for bibliometric analysis. Geaney ou al. performed bibliometric analysis and density-equalizing mapping on medical publications related to type 2 diabetes mellitus. They collected citation data and applied various citation-oriented measures including the number of info, the average quantity of citations per journal, the overall number of publications, impact element, and eigenfactor score. To conduct articles analysis and study the collaboration routine between authors and the core sub-field of AIDS, Macías-Chapula and Mijangos-Nolasco analyzed MeSH synonym replacement tool using verify tags, primary headings, and subheadings of every MeSH term hierarchy. In addition , to measure the national study productivity, that they used the authors’ talk about information. Bornmann and Mutz lately identified the development of modern scientific research by bibliometric analysis. That they divide the info into 3 time periods to assess the changes of fields as time passes.

The goal of this kind of work is to provide an exploration of different study areas within just bioinformatics, identify hot areas and show just how these areas interact with one other. We execute a two-pronged analysis to accomplish this goal. Initially, we examine keywords and the popularity in each year to understand trends in popular analysis. A network of top keywords was designed to identify clusters within these kinds of popular areas to observe connections. Next, all of us apply topic modeling in abstracts to identify salient research themes in greater fine detail than keywords. These topics are complementary to styles identified coming from keywords. A network of topics is created to show just how these study themes overlap and connect to each other. All of us explore eventual analysis of 10 curated topics to recognize how study topics tendency over time.

Biography: Characterising interaction interfaces on the sequence level

www.SCOPPI.org is actually a database of structural proteins interactions. It truly is based on set ups deposited in PDB. There is certainly still an enormous gap involving the number set ups and the amount sequences readily available. One way to close this distance will be to characterise interfaction interfaces at the collection level. For this end, students will analyse the collection profiles and residue make up of interaction interfaces for selected superfamilies in SCOPPI. The causing characterisation will be evaluated against existing constructions and interactions and utilized to predict conversation interfaces of sequences with unknown framework.

Background

Through the years, academic subject areas have converged to form a number of new, interdisciplinary fields. Bioinformatics is an example. Research fields from molecular biology to machine learning are used together to better figure out complex biological systems including cells, damaged tissues, and the body of a human. Due to the complexity and broadness of the field, bibliometric analysis is often implemented to assess the present knowledge composition of a subject area, specify the present research designs, and determine the primary literature of these area .

Bibliometrics identifies research trends using quantitative procedures such as a researcher’s number of guides and details, journal impact factors, and other indices that may measure effects or productivity of author or record [2–5]. In addition , other factors such as the affiliation of writers, collaborations, and citation info are often incorporated into bibliometric analysis [6–9].

Previous studies mainly rely on quantitative measures and suffer from having less content evaluation. To incorporate articles analysis into bibliometrics, text-mining techniques will be applied. Topic-modeling techniques are mostly adopted to recognize the subject areas of a area of interest while examining that area more abundantly [10–13]. These techniques allow for enriched content research. As an extension of Latent Dirichlet Portion (LDA), which is the best received topic-modeling technique, Steyvers et al. proposed the author-topic modeling technique that analyzes writers and matters simultaneously. They will identify the authors’ effect or output of researchers in a given subject area [15, 16]. By adding multiple conditions to LDA, Tang et ing. suggested a new technique, called the Author-Conference-Topic (ACT) model that analyzes the author, conference, and topic in one model to comprehend the subject place in an bundled manner.

From this paper, we all apply the ACT unit to examine interdisciplinary nature of bioinformatics. As opposed to studies involving extended versions of LDA for topic analysis, the ACT model enables us to analyze topic, creator, and log at one time, featuring an integrated perspective for understanding bioinformatics. The study questions that people are to check out in this newspaper are: 1) What are the topical trends of bioinformatics over time? 2) Who are definitely the key members in significant topics of bioinformatics?, and 3) Which usually journal can be leading which will topic?

To address these inquiries, we accumulate PubMed articles or blog posts in XML format and extract metadata and content such as the PMID, author, season, journal, title, and fuzy. From the name and fuzy, we extract keyphrases, which provide even more meaningful interpretations than sole words, while an suggestions of the WORK model. We all also divide the gathered datasets in four time periods to examine the topic changes as time passes. The results of ACTION model–based research show that various issues begin to appear and blended subject matters become more apparent over time.

The rest of the paper can be organized as follows. In the Background section, we go over work associated with bibliometric evaluation and matter modeling. We then describe the suggested method inside the Methods section. We evaluate and discuss the effects of leading topics, creators, and magazines in the Consequence and Discussion section. Finally, we deduce the daily news and recommend future lines of query in Conclusions.

Research in Recognition and Functional Categorization of miRNAs

MicroRNAs (miRNAs) are part of a just lately identified number of the large category of non-coding RNAs. The adult miRNA is generally 19–27 nucleotides long and is also derived from a bigger precursor that folds in an not perfect stem-loop structure. The setting of actions of the adult miRNA in mammalian systems is dependent in complementary bottom pairing mostly to the 3’UTR region of the target mRNA, thereafter leading to the inhibition of translation and/or the degradation from the mRNA. In accordance to latest estimates, although over thirty percent of vertebrate genomes is definitely transcribed (2), only 1% consists of code genes, recommending that the rest must be various kinds of non-coding RNA family genes.

Our laboratory work in the miRNA discipline focuses on the introduction of computational methods and equipment for (1) the recognition of book miRNA genetics, (2) the identification from the mature portion of the miRNA and (3) the accurate prediction of miRNA targets. Toward this target we incorporate computational with experimental approches in collaboration with Kriton Kalantidis at IMBB-FORTH as well as the Department of Biology, College or university of Crete.
