Use of animation in teaching cell biology

To address the different learning styles of students, and because students can access animation from off-campus computers, the use of digital animation in teaching cell biology has become increasingly popular. Sample processes from cell biology that are more clearly presented in animation than in static illustrations are identified. The value of animation is evaluated on whether the process being taught involves motion, cellular location, or sequential order of numerous events. Computer programs for developing animation and animations associated with cell biology textbooks are reviewed, and links to specific examples of animation are given. Finally, future teaching tools for all fields of biology will increasingly benefit from an expansion of animation to the use of simulation. One purpose of this review is to encourage the widespread use of animations in biology teaching by discussing the nature of digital animation.     

Workshop on molecular animation

From February 25 to 26, 2010, in San Francisco, the Resource for Biocomputing, Visualization, and Informatics (RBVI) and the National Center for Macromolecular Imaging (NCMI) hosted a molecular animation workshop for 21 structural biologists, molecular animators, and creators of molecular visualization software. Molecular animation aims to visualize scientific understanding of biomolecular processes and structures. The primary goal of the workshop was to identify the necessary tools for producing high-quality molecular animations, understanding complex molecular and cellular structures, creating publication supplementary materials and conference presentations, and teaching science to students and the public. Another use of molecular animation emerged in the workshop: helping to focus scientific inquiry about the motions of molecules and enhancing informal communication within and between laboratories.     

The Electron Microscopy Outreach Program: A Web-based resource for research and education

We have developed a centralized World Wide Web (WWW)-based environment that serves as a resource of software tools and expertise for biological electron microscopy. A major focus is molecular electron microscopy, but the site also includes information and links on structural biology at all levels of resolution. This site serves to help integrate or link structural biology techniques in accordance with user needs. The WWW site, called the Electron Microscopy (EM) Outreach Program (URL: http://emoutreach.sdsc.edu), provides scientists with computational and educational tools for their research and edification. In particular, we have set up a centralized resource containing course notes, references, and links to image analysis and three-dimensional reconstruction software for investigators wanting to learn about EM techniques either within or outside of their fields of expertise.     

Metabolic modeling of microbial strains in silico

The large volume of genome-scale data that is being produced and made available in databases on the World Wide Web is demanding the development of integrated mathematical models of cellular processes. The analysis of reconstructed metabolic networks as systems leads to the development of an in silico or computer representation of collections of cellular metabolic constituents, their interactions and their integrated function as a whole. The use of quantitative analysis methods to generate testable hypotheses and drive experimentation at a whole-genome level signals the advent of a systemic modeling approach to cellular and molecular biology.     

Using the Saccharomyces Genome Database (SGD) for analysis of protein similarities and structure.

The Saccharomyces Genome Database (SGD) collects and organizes information about the molecular biology and genetics of the yeast Saccharomyces cerevisiae. The latest protein structure and comparison tools available at SGD are presented here. With the completion of the yeast sequence and the Caenorhabditis elegans sequence soon to follow, comparison of proteins from complete eukaryotic proteomes will be an extremely powerful way to learn more about a particular protein's structure, its function, and its relationships with other proteins. SGD can be accessed through the World Wide Web at http://genome-www.stanford.edu/Saccharomyces/     

Laboratory protocols on the internet

Summary The World Wide Web (WWW) is of major significance to the Biotechnologist. One of the fastest growing and most useful areas of the internet, the WWW contains information sites, genome and sequence databases, newsgroups and forums, search and comparison tools, and electronic journals. To many scientists, the WWW has become an indispensable research tool. This paper lists some of the sites providing a wide range of relevant protocols and techniques and describes how to access this information.     

Integration of tools and resources for display and analysis of genomic data for protozoan parasites

Centralisation of tools for analysis of genomic data is paramount in ensuring that research is always carried out on the latest currently available data. As such, World Wide Web sites providing a range of online analyses and displays of data can play a crucial role in guaranteeing consistency of in silico work. In this respect, the protozoan parasite research community is served by several resources, either focussing on data and tools for one species or taking a broader view and providing tools for analysis of data from many species, thereby facilitating comparative studies. In this paper, we give a broad overview of the online resources available. We then focus on the GeneDB project, detailing the features and tools currently available through it. Finally, we discuss data curation and its importance in keeping genomic data 'relevant' to the research community.     

MUTbase: maintenance and analysis of distributed mutation databases

MOTIVATION: To develop tools for the submission of mutations to databases and maintenance of locus-specific mutation databases. Advanced, integrated computer systems are needed to store and organize the increasing mutation information. RESULTS: The MUTbase program suite provides an easy, interactive and quality-controlled submission of information to mutation databases. For further study of the databases on the World Wide Web, a number of tools are provided. The program package also writes and updates a large number of Web pages, e.g. about the distribution and statistics of disease-causing mutations, and changes in restriction patterns.     

FisOmics: A portal of fish genomic resources

An online portal, accessible at URL: http://mail.nbfgr.res.in/FisOmics/, was developed that features different genomic databases and tools. The portal, named as FisOmics, acts as a platform for sharing fish genomic sequences and related information in addition to facilitating the access of high-performance computational resources for genome and proteome data analyses. It provides the ability for quarrying, analysing and visualizing genomic sequences and related information. The featured databases in FisOmics are in the World Wide Web domain already. The aim to develop portal was to provide a nodal point to access the featured databases and work conveniently. Presently, FisOmics includes databases on barcode sequences, microsatellite markers, mitogenome sequences, hypoxia-responsive genes and karyology of fishes. Besides, it has a link to other molecular resources and reports on the on-going activities and research achievements.     

Biological SOAP servers and web services provided by the public sequence data bank

A number of biological data resources (i.e. databases and data analytical tools) are searchable and usable on-line thanks to the internet and the World Wide Web (WWW) servers. The output from the web server is easy for us to browse. However, it is laborious and sometimes impossible for us to write a computer program that finds a useful data resource, sends a proper query and processes the output. It is a serious obstacle to the integration of distributed heterogeneous data resources. To solve the issue, we have implemented a SOAP (Simple Object Access Protocol) server and web services that provide a program-friendly interface. The web services are accessible at http://www.xml.nig.ac.jp/.     

Bioinformatics data distribution and integration via Web Services and XML

It is widely recognized that exchange, distribution, and integration of biological data are the keys to improve bioinformatics and genome biology in post-genomic era. However, the problem of exchanging and integrating biological data is not solved satisfactorily. The extensible Markup Language (XML) is rapidly spreading     

PCR primer design: an inquiry-based introduction to bioinformatics on the World Wide Web

A project is described which details the selection of PCR primers for an unknown gene of the Herpes Simplex Virus (Type 1) using tools available on the World Wide Web. Within the context of designing PCR primers, students are introduced to some of the basic tools used in the field of bioinformatics and have the opportunity to further develop the concepts of nucleic acid sequence and structure, based on the analysis of selected nucleotide primers.     

Animated life cycles of fungi and plants with spores for teaching

The conveyance of knowledge of the life cycles performed by fungi and plants with spores is a challenge for teaching in university education. The life cycles of fungi, in particular, can be very complex and difficult to understand. This paper presents the development and implementation of a German and English educational software program, including seven animated life cycles of fungi, two animated developments of fungal meiosporangia, and two examples each for ferns, mosses, and algae (cryptogams). We could show that the use of the software supported the study of fungi and spore-producing plants. It was possible to identify attributes of usability that contributed to a high quality of the educational material in concrete teaching situations. Notably, an easy handling of the software and an appropriate amount of information per animation step are crucial. In addition to the didactic insights, the conversations between the animation designers and the mycologist on correct details of developmental processes in the animations lead to interesting questions concerning cell biology. Some of the resulting open questions are at the edge of currently available knowledge, e.g. concerning the transformation of a plasmodium into a high number of small fruiting bodies in myxomycetes or the dikaryotisation of monokaryotic hyphae after spermatisation in rust fungi.     

Integrating T-cell epitope annotations with sequence and structural information using DAS

Immunoinformatics is an emerging new field that benefits from computational analyses and tools that facilitate the understanding of the immune system. A large number of immunoinformatics resources such as immune-related databases and analysis software are available through the World Wide Web for the benefit of the research community. However, immunoinformatics developments have sometimes remained isolated from mainstream bioinformatics. Therefore, there is clearly a need for integration, which will empower the exchange of data and annotations within the scientific community in a quick and efficient fashion. Here, we have chosen the Distributed Annotation System (DAS), for integrating in house annotations on experimental and predicted HLA I-restriction elements of CD8 T-cell epitopes with sequence and structural information.     

A perspective on healthcare related web interfaces

Consumer retrieval of health information through the internet has become prevalent. In the past, physicians provided filtered health information to the consumer. However, the availability of health related information including disease specific research trends over the World Wide Web is useful for clinicians and consumers. The use of internet based health care information by clinicians and consumers have increased in recent years. Nonetheless, consumers often have difficulties in evaluating such data in a comprehensive manner. Here, we describe the current status of health care related data over the World Wide Web.     

Analysis of the Candida albicans proteome. II. Protein information technology on the Net (update 2002)

Candida albicans is an important fungal model organism of noteworthy clinical interest in modern medicine. Different initiatives addressing its sequencing and physical mapping have been carried out. The C. albicans genome sequence is currently near to completion at Stanford University, heralding new challenges in proteomic research and functional analyses of its gene products. This review presents an update of the most relevant data resources that are available through the World Wide Web to scientists working in the area of the analysis of the C. albicans proteome. An overview of the current status of the main universal protein sequence databases and specialized data collections for C. albicans is given. Various issues of the single public C. albicans 2D-PAGE database are also described, highlighting the significance of setting up graphical query interface-based databanks to visualize 2D-PAGE images through the Net. Finally, we also emphasize the pressing need to create a "cyber-bioknowledge library" that will integrate all the databases developed at the different levels for the understanding of life processes as well as bioinformatic tools for interpreting this deluge of data generated through the Internet.     

PANORAMA: an integrated Web-based sequence analysis tool and its role in gene discovery

As the exponential growth of DNA sequence information in databases continues, the task of converting this deposited information into knowledge becomes more dependent on integrative sequence analysis and visualization tools. PANORAMA is an Internet-accessible software package that performs a variety of informatics analyses on a given DNA sequence and returns a visual and interactive representation of the results. Its design is modular, so that further sequence analysis tools can be integrated with minimal effort. The utility of PANORAMA is demonstrated in the analysis of 650 kb of human genomic DNA from chromosome region 3p21.3, a region of potential tumor suppressor genes involved in lung cancer, breast cancer, and other forms of cancer. PANORAMA aided in the discovery of genes and alternate splice forms of known exons, in the demarcation of intron-exon boundaries, and in the identification of promoter regions and polymorphisms, all of which contributed to a better understanding of the region. PANORAMA is available on the World Wide Web at http://atlas.swmed.edu.     

The protein kinase resource and other bioinformation resources

The Internet, especially the World Wide Web has transformed how today's researchers communicate, share information, and analyze their data. Unfortunately, the vast number of online databases, information resources and analytical tools, some of them masked by unfamiliar titles and Internet addresses, has hindered their universal and effective use by the research community. To overcome these hurdles, subject- and function-specific compendiums are now available which organize information and online tolls in a manner familiar to the biological researcher. The Protein Kinase Resource and the CMS Molecular Biology Resource are two excellent examples of web compendia.
