SimTK Core is one of the two packages that together constitute SimTK, the biosimulation toolkit from the Simbios Center. The other major component of SimTK is OpenMM which is packaged separately. This SimTK Core project collects together all the binaries needed for the various SimTK Core subprojects. These include Simbody, Molmodel, Simmath (including Ipopt), Simmatrix, CPodes, SimTKcommon, and Lapack. See the individual projects for descriptions. SimTK brings together in a robust, convenient, open source form the collection of highly-specialized technologies necessary to building successful physics-based simulations of biological structures. These include: strict adherence to an important set of abstractions and guiding principles, robust, high-performance numerical methods, support for developing and sharing physics-based models, and careful software engineering. Accessible High Performance Computing We believe that a primary concern of simulation scientists is performance, that is, speed of computation. We seek to build valid, approximate models using classical physics in order to achieve reasonable run times for our computational studies, so that we can hope to learn something interesting before retirement. In the choice of SimTK technologies, we are focused on achieving the best possible performance on hardware that most researchers actually have. In today''s practice, that means commodity multiprocessors and small clusters. The difference in performance between the best methods and the do-it-yourself techniques most people use can be astoundingeasily an order of magnitude or more. The growing set of SimTK Core libraries seeks to provide the best implementation of the best-known methods for widely used computations such as: Linear algebra, numerical integration and Monte Carlo sampling, multibody (internal coordinate) dynamics, molecular force field evaluation, nonlinear root finding and optimization. All SimTK Core software is in the form of C++ APIs, is thread-safe, and quietly exploits multiple CPUs when they are present. The resulting pre-built binaries are available for download and immediate use. Audience: Biosimulation application programmers interested in including robust, high-performance physics-based simulation in their domain-specific applications.

A simple Java graphical user interface for running the program ISIM. ISIM is a package that simulates the thermodynamic ensemble of ions around a macromolecule using a grand canonical Monte Carlo scheme and simple hard sphere ion models. It is meant to provide an alternative mechanism to mean field approaches to allow the calculation of ion distributions around a highly charged molecule using a simple model that takes into account ion-ion correlations and steric interactions. The original source was created in the McCammon group at UCSD but is no longer available. The version of ISIM used is available in the ISIM project on simtk.org.

MRIcro allows Windows and Linux computers view medical images. It is a standalone program, but includes tools to complement SPM (software that allows neuroimagers to analyze MRI, fMRI and PET images). MRIcro allows efficient viewing and exporting of brain images. In addition, it allows neuropsychologists to identify regions of interest (ROIs, e.g. lesions). MRIcro can create Analyze format headers for exporting brain images to other platforms. Some features of MRIcro are: - Converts medical images to SPM friendly Analyze format. - View Analyze format images (big or little endian). - Create Analyze format headers (big or little endian). - Create 3D regions of interest (with computed volume & intensity). - Overlap multiple regions of interest. - Rotate images to match SPM template images. - Export images to BMP, JPEG, PNG or TIF format. - Yoked images: linked viewing of multiple images (e.g. view same coordinates of PET and MRI scans). Users familiar with other Windows programs will find that this software is fairly straightforward to use. Resting the mouse cursor over a button will cause a text hint to appear over the button. However, a tutorial with a step by step guide of how to use MRIcro with SPM is available.

THIS RESOURCE IS NO LONGER IN SERVICE, documented on August 11, 2015. A searchable database for epidemiologic research on aging changes across the lifespan. In 2003, the National Institute on Aging (NIA) established the Longitudinal Data on Aging (LDA) working group to assist with the development of research initiatives for identifying the physiologic and other types of factors across the lifespan, affecting onset and progression of disease with advancing age, as well as elucidation of protective factors contributing to exceptionally healthy aging. This database was developed based on input from the LDA working group which indicated that establishing a database of existing sources of longitudinal data on aging (e.g., ongoing longitudinal cohorts, longitudinal data sets, biospecimen repositories) would be a valuable resource for facilitating future research on aging changes across the lifespan. The longitudinal studies, data sets and repositories included in this database encompass a wide range of age groups (childhood to old age), studies in minority populations, as well as sources of longitudinal data existing in the United States and abroad. Our primary purpose for establishing this database is to provide a resource for potential applicants for grants to the NIA. No part of this database can be used for commercial purposes.

A portal to educate, engage and create an online community. The Fisher Center for Alzheimer''s Research Foundation, founded in 1995, was created in answer to the recommendations of three U.S. Senate commissioned symposia held in the 1990s by the National Institutes of Health (NIH) to gather information on the cause, care and cure of Alzheimer''s disease. The Fisher Center was created following this design. The funding initiatives of the Foundation are appropriated accordingly to the three areas cited by the NIH task force cause, care and cure. The primary resources of the Foundation are directed toward scientific research into the cause and hopefully the cure of Alzheimer''s disease. To this end, the Foundation under the direction of its founder, Zachary Fisher, and in collaboration with David Rockefeller, constructed the Fisher Center for Alzheimer''s Disease Research at The Rockefeller University, headed by 2000 Nobel Prize winner, Paul Greengard, Ph.D. The 10,000 square foot laboratory is the most advanced facility of its kind in the country equipped with the latest in equipment necessary to undertake an interdisciplinary assault on this disease. The Fisher Center also has collaborative programs at the University of Genoa and supports the work of well over 60 scientists and researchers across the United States and in 17 foreign countries. The Foundation also funds projects for the care of people with Alzheimer''s disease and their caregivers. The Fisher Alzheimer''s Disease Education and Resources Program at the New York University School of Medicine was established under the direction of Barry Reisberg, M.D., internationally known expert in the care of Alzheimer''s patients. The Foundations Alzheimer''s Information Program was created in 2001 to answer the primary need of caregivers for comprehensive, easily accessible information. Our goals are to: Understand the Cause of Alzheimer''s To find a Cure for this devastating disease Improve the Care of people living with the disease to enhance their quality of life and that of their caregivers and families About Our Research Beating Back Beta Amyloid Improving the Quality of Life for Alzheimers Patients Reversing Nerve Cell Damage Using Hormones to Slow the Progress of Disease Curing Early-Onset Alzheimers The Science of Caregiving Scientific Studies

A human full-length cDNA sequence analysis database focused on mRNA varieties caused by variations of transcription start site (TSS) and splicing. Also available is ATGpr, a program for identifying the translational initiation codons in cDNA sequences. Data are derived from several full-length cDNA studies in Japan. Human gene number was estimated to be 20-25 thousand. However, the number of human mRNA varieties was predicted to be about 100 thousand. The varieties are thought to be caused by variations of TSS and splicing. In their previous human cDNA project, about 30 thousand of FLJ human full-length sequenced cDNAs were deposited to DDBJ/GenBank/EMBL, and they obtained about 1.4 million of 5''-end sequences (5''-EST) of FLJ full-length cDNAs from about 100 kinds of cDNA libraries consist of human tissues and cells constructed by oligo-capping method. The majority of the insert cDNA sizes were over 2 kb and the full-length rate of 5''-end was 90. And our FLJ cDNAs were covered about 80 of human genes. About 22 thousand of finished grades of full-length sequenced cDNAs were obtained in this project. The sequence analysis databases is focused on mRNA variations using human genome and cDNA sequences, FLJ full-length sequenced cDNAs, 5-ESTs of FLJ full-length cDNAs and other cDNA sequences described below. After those sequences were mapped onto the human genome sequences, clustering of the cDNA sequences were done based on the mapping results.

Launched in 2004, the HIV Guide is a single disease resource, with two main parts: the HIV database, which is accessed by searching on diagnosis, drug name, pathogen, or management or by accessing the resistance tool, and there are also browsable areas of the site, which include news, features, continuing medical education programs and other types of additional readings and information. Guides are authored by academic clinicians and subject to rigorous peer review. You may browse the guide by: Diagnosis Covering opportunistic infections, malignancies, and complications of therapy. Drugs Includes indications, dosing, drug interactions, and author recommendations. Pathogen - Describes microbiology, clinical syndromes, and therapy. Management Including antiretroviral therapy guidelines and strategies. Resistance Tool Provides up-to-date interpretation of genotypic resistance test results. Whether searching for a drug, a pathogen, a diagnosis, or a management issue, your search results will be delivered in a concise and standard form designed to give you the most clinically useful information first, with the option to go deeper if you choose. If you search by diagnosis, you will receive a page listing points covering establishment of a diagnosis, related pathogens, treatment recommendations, issues to consider on follow up, references and more. At each step, we provide you immediately with the information you need to treat the diagnosis and give you the option to read more or more deeply if you choose. On the diagnosis page, you are also provided with links to the information sheet for each drug that may be prescribed, and if you indicate which drug you intend to use, you will be provided with relevant drug selected comments. If you search by drug, you will receive a page listing FDA indications, usual adult dosing, adverse drug reactions, drug interactions, spectrum, and forms. You are also able to access full pharmacological information (mechanism, absorption, Cmax, volume of distribution, protein binding, metabolism/excretion, t _, dosing for glomerular filtration of 50-80, dosing for glomerular filtration of 10-50, dosing for glomerular filtration of <10 ml/min, dosing in hemodialysis, dosing in peritoneal dialysis, dosing in cavh, dosing for decreased hepatic function, pregnancy risk, and breast feeding compatibility). If you search by pathogen, you will receive a page covering the microbiology, clinical relevance, sites of infection, drug selected comments, other information and references. You are also provided with links to information for each drug that may be prescribed, and if you indicate which drug you intend to use, you will be provided with the drug selected comments for that choice. If you search by management, you will receive a page listing definition, indications, and clinical recommendations and additional details, including references. If you click on more wherever it appears on a page, you will find more detailed material about the topic. In addition, the HIV Guide homepage contains a Features section and Literature Review that contain synopses and articles about pertinent topics. The Publications section also provides .pdf versions of the Hopkins HIV Report. Prices represent the cost per unit specified, reflecting the Average Wholesale Price (AWP). AWP prices are taken from the Red Book, manufacturer information, and the McKesson database. These prices are updated every six months. We have listed up to 10 FDA-approved indications for uses of drugs. Though in some cases more may exist, for brevity and formatting issues authors and editors have chosen what they deem the most important. Also listed are disease states for which a drug may be likely prescribed regardless of FDA approval status (see Non-FDA approved uses). The HIV Guide is primarily focused on adult care but does cover issues of perinatal transmission. The material presented on this site represents the considered opinion of the Hopkins expert listed as the author of the module as of the date indicated. The reference section contains an annotated list of the articles that the author considers to be most relevant to the topic. Where authoritative guidelines exist, such as CDC, IDSA or Medical Letter guidelines, they are referenced and discussed along with the author''s recommendations presented.

The JCSG is a multi-institutional consortium that aims to explore the expanding protein universe to find new challenges and opportunities to significantly contribute to new biology, chemistry and medicine through development of HT approaches to structural genomics. The mission of JCSG is to to operate a robust HT protein structure determination pipeline as a large-scale production center for PSI-2. A major goal is to ensure that innovative high-throughput approaches are developed that advance not only structural genomics, but also structural biology in general, via investigation of large numbers of high-value structures that populate protein fold and family space and by increasing the efficiency of structure determination at substantially reduced cost. The JCSG centralizes each core activity into single dedicated sites, each handling distinct, but interconnected objectives. This unique approach allows each specialized group to focus on its own area of expertise and provides well-defined interfaces among the groups. In addition, this approach addresses the requirements for the scalability needed to process large numbers of targets at a greatly reduced cost per target. JCSG production groups are: - Administrative Core - Bioinformatics Core - Crystallomics Core - Structure Determination Core - NMR Core JCSG is deeply committed to the development of new technologies that facilitate high throughput structural genomics. The areas of development include hardware, software, new experimental methods, and adaptation of existing technologies to advance genome research. In the hardware arena, their commitment is to the development of technologies that accelerate structure solution by increasing throughput rates at every stage of the production pipeline. Therefore, one major area of hardware development has been the implementation of robotics. In the software arena, they have developed enterprise resource software that track success, failures, and sample histories from target selection to PDB deposition, annotation and target management tools, and helper applications aimed at facilitating and automating multiple steps in the pipeline. Sponsors: The Joint Center for Structural Genomics is funded by the National Institute of General Medical Sciences (NIGMS), as part of the second phase of the Protein Structure Initiative (PSI) of the National Institutes of Health (U54 GM074898).
