Stem Trace: an interactive visual tool for comparative RNA structure analysis. (1/2878)

MOTIVATION: Stem Trace is one of the latest tools available in STRUCTURELAB, an RNA structure analysis computer workbench. The paradigm used in STRUCTURELAB views RNA structure determination as a problem of dealing with a database of a large number of computationally generated structures. Stem Trace provides the capability to analyze this data set in a novel, visually driven, interactive and exploratory way. In addition to providing graphs at a high level of ion, it is also connected with complementary visualization tools which provide orthogonal views of the same data, as well as drawing of structures represented by a stem trace. Thus, on top of being an analysis tool, Stem Trace is a graphical user interface to an RNA structural information database. RESULTS: We illustrate Stem Trace's capabilities with several examples of the analysis of RNA folding data performed on 24 strains of HIV-1, HIV-2 and SIV sequences around the HIV dimerization region. This dimer linkage site has been found to play a role in encapsidation, reverse transcription, recombination, and inhibition of translation. Our examples show how Stem Trace elucidates preservation of structures in this region across the various strains of HIV. AVAILABILITY: The program can be made available upon request. It runs on SUN, SGI and DEC (Compaq) Unix workstations.  (+info)

E-CELL: software environment for whole-cell simulation. (2/2878)

MOTIVATION: Genome sequencing projects and further systematic functional analyses of complete gene sets are producing an unprecedented mass of molecular information for a wide range of model organisms. This provides us with a detailed account of the cell with which we may begin to build models for simulating intracellular molecular processes to predict the dynamic behavior of living cells. Previous work in biochemical and genetic simulation has isolated well-characterized pathways for detailed analysis, but methods for building integrative models of the cell that incorporate gene regulation, metabolism and signaling have not been established. We, therefore, were motivated to develop a software environment for building such integrative models based on gene sets, and running simulations to conduct experiments in silico. RESULTS: E-CELL, a modeling and simulation environment for biochemical and genetic processes, has been developed. The E-CELL system allows a user to define functions of proteins, protein-protein interactions, protein-DNA interactions, regulation of gene expression and other features of cellular metabolism, as a set of reaction rules. E-CELL simulates cell behavior by numerically integrating the differential equations described implicitly in these reaction rules. The user can observe, through a computer display, dynamic changes in concentrations of proteins, protein complexes and other chemical compounds in the cell. Using this software, we constructed a model of a hypothetical cell with only 127 genes sufficient for transcription, translation, energy production and phospholipid synthesis. Most of the genes are taken from Mycoplasma genitalium, the organism having the smallest known chromosome, whose complete 580 kb genome sequence was determined at TIGR in 1995. We discuss future applications of the E-CELL system with special respect to genome engineering. AVAILABILITY: The E-CELL software is available upon request. SUPPLEMENTARY INFORMATION: The complete list of rules of the developed cell model with kinetic parameters can be obtained via our web site at:  (+info)

The high-resolution crystal structure of the molybdate-dependent transcriptional regulator (ModE) from Escherichia coli: a novel combination of domain folds. (3/2878)

The molybdate-dependent transcriptional regulator (ModE) from Escherichia coli functions as a sensor of molybdate concentration and a regulator for transcription of operons involved in the uptake and utilization of the essential element, molybdenum. We have determined the structure of ModE using multi-wavelength anomalous dispersion. Selenomethionyl and native ModE models are refined to 1. 75 and 2.1 A, respectively and describe the architecture and structural detail of a complete transcriptional regulator. ModE is a homodimer and each subunit comprises N- and C-terminal domains. The N-terminal domain carries a winged helix-turn-helix motif for binding to DNA and is primarily responsible for ModE dimerization. The C-terminal domain contains the molybdate-binding site and residues implicated in binding the oxyanion are identified. This domain is divided into sub-domains a and b which have similar folds, although the organization of secondary structure elements varies. The sub-domain fold is related to the oligomer binding-fold and similar to that of the subunits of several toxins which are involved in extensive protein-protein interactions. This suggests a role for the C-terminal domain in the formation of the ModE-protein-DNA complexes necessary to regulate transcription. Modelling of ModE interacting with DNA suggests that a large distortion of DNA is not necessary for complex formation.  (+info)

X-ray structure of T4 endonuclease VII: a DNA junction resolvase with a novel fold and unusual domain-swapped dimer architecture. (4/2878)

Phage T4 endonuclease VII (Endo VII), the first enzyme shown to resolve Holliday junctions, recognizes a broad spectrum of DNA substrates ranging from branched DNAs to single base mismatches. We have determined the crystal structures of the Ca2+-bound wild-type and the inactive N62D mutant enzymes at 2.4 and 2.1 A, respectively. The Endo VII monomers form an elongated, highly intertwined molecular dimer exhibiting extreme domain swapping. The major dimerization elements are two pairs of antiparallel helices forming a novel 'four-helix cross' motif. The unique monomer fold, almost completely lacking beta-sheet structure and containing a zinc ion tetrahedrally coordinated to four cysteines, does not resemble any of the known junction-resolving enzymes, including the Escherichia coli RuvC and lambda integrase-type recombinases. The S-shaped dimer has two 'binding bays' separated by approximately 25 A which are lined by positively charged residues and contain near their base residues known to be essential for activity. These include Asp40 and Asn62, which function as ligands for the bound calcium ions. A pronounced bipolar charge distribution suggests that branched DNA substrates bind to the positively charged face with the scissile phosphates located near the divalent cations. A model for the complex with a four-way DNA junction is presented.  (+info)

The three-dimensional structure of the RNA-binding domain of ribosomal protein L2; a protein at the peptidyl transferase center of the ribosome. (5/2878)

Ribosomal protein L2 is the largest protein component in the ribosome. It is located at or near the peptidyl transferase center and has been a prime candidate for the peptidyl transferase activity. It binds directly to 23S rRNA and plays a crucial role in its assembly. The three-dimensional structure of the RNA-binding domain of L2 from Bacillus stearothermophilus has been determined at 2.3 A resolution by X-ray crystallography using the selenomethionyl MAD method. The RNA-binding domain of L2 consists of two recurring motifs of approximately 70 residues each. The N-terminal domain (positions 60-130) is homologous to the OB-fold, and the C-terminal domain (positions 131-201) is homologous to the SH3-like barrel. Residues Arg86 and Arg155, which have been identified by mutation experiments to be involved in the 23S rRNA binding, are located at the gate of the interface region between the two domains. The molecular architecture suggests how this important protein has evolved from the ancient nucleic acid-binding proteins to create a 23S rRNA-binding domain in the very remote past.  (+info)

Crystal structure of a heparin- and integrin-binding segment of human fibronectin. (6/2878)

The crystal structure of human fibronectin (FN) type III repeats 12-14 reveals the primary heparin-binding site, a clump of positively charged residues in FN13, and a putative minor site approximately 60 A away in FN14. The IDAPS motif implicated in integrin alpha4beta1 binding is at the FN13-14 junction, rendering the critical Asp184 inaccessible to integrin. Asp184 clamps the BC loop of FN14, whose sequence (PRARI) is reminiscent of the synergy sequence (PHSRN) of FN9. Mutagenesis studies prompted by this observation reveal that both arginines of the PRARI sequence are important for alpha4beta1 binding to FN12-14. The PRARI motif may represent a new class of integrin-binding sites. The spatial organization of the binding sites suggests that heparin and integrin may bind in concert.  (+info)

A trans-acting peptide activates the yeast a1 repressor by raising its DNA-binding affinity. (7/2878)

The cooperative binding of gene regulatory proteins to DNA is a common feature of transcriptional control in both prokaryotes and eukaryotes. It is generally viewed as a simple energy coupling, through protein-protein interactions, of two or more DNA-binding proteins. In this paper, we show that the simple view does not account for the cooperative DNA binding of a1 and alpha2, two homeodomain proteins from budding yeast. Rather, we show through the use of chimeric proteins and synthetic peptides that, upon heterodimerization, alpha2 instructs a1 to bind DNA. This change is induced by contact with a peptide contributed by alpha2, and this contact converts a1 from a weak to a strong DNA-binding protein. This explains, in part, how high DNA-binding specificity is achieved only when the two gene regulatory proteins conjoin. We also provide evidence that features of the a1-alpha2 interaction can serve as a model for other examples of protein-protein interactions, including that between the herpes virus transcriptional activator VP16 and the mammalian homeodomain-containing protein Oct-l.  (+info)

Golgi structure in three dimensions: functional insights from the normal rat kidney cell. (8/2878)

Three-dimensional reconstructions of portions of the Golgi complex from cryofixed, freeze-substituted normal rat kidney cells have been made by dual-axis, high-voltage EM tomography at approximately 7-nm resolution. The reconstruction shown here ( approximately 1 x 1 x 4 microm3) contains two stacks of seven cisternae separated by a noncompact region across which bridges connect some cisternae at equivalent levels, but none at nonequivalent levels. The rest of the noncompact region is filled with both vesicles and polymorphic membranous elements. All cisternae are fenestrated and display coated buds. They all have about the same surface area, but they differ in volume by as much as 50%. The trans-most cisterna produces exclusively clathrin-coated buds, whereas the others display only nonclathrin coated buds. This finding challenges traditional views of where sorting occurs within the Golgi complex. Tubules with budding profiles extend from the margins of both cis and trans cisternae. They pass beyond neighboring cisternae, suggesting that these tubules contribute to traffic to and/or from the Golgi. Vesicle-filled "wells" open to both the cis and lateral sides of the stacks. The stacks of cisternae are positioned between two types of ER, cis and trans. The cis ER lies adjacent to the ER-Golgi intermediate compartment, which consists of discrete polymorphic membranous elements layered in front of the cis-most Golgi cisterna. The extensive trans ER forms close contacts with the two trans-most cisternae; this apposition may permit direct transfer of lipids between ER and Golgi membranes. Within 0.2 microm of the cisternae studied, there are 394 vesicles (8 clathrin coated, 190 nonclathrin coated, and 196 noncoated), indicating considerable vesicular traffic in this Golgi region. Our data place structural constraints on models of trafficking to, through, and from the Golgi complex.  (+info)

I am not aware of a widely accepted medical definition for the term "software," as it is more commonly used in the context of computer science and technology. Software refers to programs, data, and instructions that are used by computers to perform various tasks. It does not have direct relevance to medical fields such as anatomy, physiology, or clinical practice. If you have any questions related to medicine or healthcare, I would be happy to try to help with those instead!

A computer simulation is a process that involves creating a model of a real-world system or phenomenon on a computer and then using that model to run experiments and make predictions about how the system will behave under different conditions. In the medical field, computer simulations are used for a variety of purposes, including:

1. Training and education: Computer simulations can be used to create realistic virtual environments where medical students and professionals can practice their skills and learn new procedures without risk to actual patients. For example, surgeons may use simulation software to practice complex surgical techniques before performing them on real patients.
2. Research and development: Computer simulations can help medical researchers study the behavior of biological systems at a level of detail that would be difficult or impossible to achieve through experimental methods alone. By creating detailed models of cells, tissues, organs, or even entire organisms, researchers can use simulation software to explore how these systems function and how they respond to different stimuli.
3. Drug discovery and development: Computer simulations are an essential tool in modern drug discovery and development. By modeling the behavior of drugs at a molecular level, researchers can predict how they will interact with their targets in the body and identify potential side effects or toxicities. This information can help guide the design of new drugs and reduce the need for expensive and time-consuming clinical trials.
4. Personalized medicine: Computer simulations can be used to create personalized models of individual patients based on their unique genetic, physiological, and environmental characteristics. These models can then be used to predict how a patient will respond to different treatments and identify the most effective therapy for their specific condition.

Overall, computer simulations are a powerful tool in modern medicine, enabling researchers and clinicians to study complex systems and make predictions about how they will behave under a wide range of conditions. By providing insights into the behavior of biological systems at a level of detail that would be difficult or impossible to achieve through experimental methods alone, computer simulations are helping to advance our understanding of human health and disease.

Molecular models are three-dimensional representations of molecular structures that are used in the field of molecular biology and chemistry to visualize and understand the spatial arrangement of atoms and bonds within a molecule. These models can be physical or computer-generated and allow researchers to study the shape, size, and behavior of molecules, which is crucial for understanding their function and interactions with other molecules.

Physical molecular models are often made up of balls (representing atoms) connected by rods or sticks (representing bonds). These models can be constructed manually using materials such as plastic or wooden balls and rods, or they can be created using 3D printing technology.

Computer-generated molecular models, on the other hand, are created using specialized software that allows researchers to visualize and manipulate molecular structures in three dimensions. These models can be used to simulate molecular interactions, predict molecular behavior, and design new drugs or chemicals with specific properties. Overall, molecular models play a critical role in advancing our understanding of molecular structures and their functions.

Protein conformation refers to the specific three-dimensional shape that a protein molecule assumes due to the spatial arrangement of its constituent amino acid residues and their associated chemical groups. This complex structure is determined by several factors, including covalent bonds (disulfide bridges), hydrogen bonds, van der Waals forces, and ionic bonds, which help stabilize the protein's unique conformation.

Protein conformations can be broadly classified into two categories: primary, secondary, tertiary, and quaternary structures. The primary structure represents the linear sequence of amino acids in a polypeptide chain. The secondary structure arises from local interactions between adjacent amino acid residues, leading to the formation of recurring motifs such as α-helices and β-sheets. Tertiary structure refers to the overall three-dimensional folding pattern of a single polypeptide chain, while quaternary structure describes the spatial arrangement of multiple folded polypeptide chains (subunits) that interact to form a functional protein complex.

Understanding protein conformation is crucial for elucidating protein function, as the specific three-dimensional shape of a protein directly influences its ability to interact with other molecules, such as ligands, nucleic acids, or other proteins. Any alterations in protein conformation due to genetic mutations, environmental factors, or chemical modifications can lead to loss of function, misfolding, aggregation, and disease states like neurodegenerative disorders and cancer.

Computer-assisted image processing is a medical term that refers to the use of computer systems and specialized software to improve, analyze, and interpret medical images obtained through various imaging techniques such as X-ray, CT (computed tomography), MRI (magnetic resonance imaging), ultrasound, and others.

The process typically involves several steps, including image acquisition, enhancement, segmentation, restoration, and analysis. Image processing algorithms can be used to enhance the quality of medical images by adjusting contrast, brightness, and sharpness, as well as removing noise and artifacts that may interfere with accurate diagnosis. Segmentation techniques can be used to isolate specific regions or structures of interest within an image, allowing for more detailed analysis.

Computer-assisted image processing has numerous applications in medical imaging, including detection and characterization of lesions, tumors, and other abnormalities; assessment of organ function and morphology; and guidance of interventional procedures such as biopsies and surgeries. By automating and standardizing image analysis tasks, computer-assisted image processing can help to improve diagnostic accuracy, efficiency, and consistency, while reducing the potential for human error.

An amino acid sequence is the specific order of amino acids in a protein or peptide molecule, formed by the linking of the amino group (-NH2) of one amino acid to the carboxyl group (-COOH) of another amino acid through a peptide bond. The sequence is determined by the genetic code and is unique to each type of protein or peptide. It plays a crucial role in determining the three-dimensional structure and function of proteins.

A User-Computer Interface (also known as Human-Computer Interaction) refers to the point at which a person (user) interacts with a computer system. This can include both hardware and software components, such as keyboards, mice, touchscreens, and graphical user interfaces (GUIs). The design of the user-computer interface is crucial in determining the usability and accessibility of a computer system for the user. A well-designed interface should be intuitive, efficient, and easy to use, minimizing the cognitive load on the user and allowing them to effectively accomplish their tasks.

I couldn't find a medical definition specific to "data display," but I can provide some information related to the visual representation of medical data.

In healthcare and research, data displays are graphical representations of data designed to facilitate understanding, communication, and interpretation of complex information. These visualizations can include various types of charts, graphs, tables, and infographics that present medical data in a more accessible and easily digestible format. Examples of data displays in a medical context may include:

1. Line graphs: Used to show trends over time, such as changes in a patient's vital signs or the progression of a disease.
2. Bar charts: Employed to compare categorical data, like the frequency of different symptoms across various patient groups.
3. Pie charts: Utilized to illustrate proportions or percentages of different categories within a whole, such as the distribution of causes of death in a population.
4. Scatter plots: Applied to display relationships between two continuous variables, like the correlation between age and blood pressure.
5. Heat maps: Used to represent density or intensity of data points across a two-dimensional space, often used for geographical data or large datasets with spatial components.
6. Forest plots: Commonly employed in systematic reviews and meta-analyses to display the effect sizes and confidence intervals of individual studies and overall estimates.
7. Flow diagrams: Used to illustrate diagnostic algorithms, treatment pathways, or patient flow through a healthcare system.
8. Icon arrays: Employed to represent risks or probabilities visually, often used in informed consent processes or shared decision-making tools.

These visual representations of medical data can aid in clinical decision-making, research, education, and communication between healthcare professionals, patients, and policymakers.

An algorithm is not a medical term, but rather a concept from computer science and mathematics. In the context of medicine, algorithms are often used to describe step-by-step procedures for diagnosing or managing medical conditions. These procedures typically involve a series of rules or decision points that help healthcare professionals make informed decisions about patient care.

For example, an algorithm for diagnosing a particular type of heart disease might involve taking a patient's medical history, performing a physical exam, ordering certain diagnostic tests, and interpreting the results in a specific way. By following this algorithm, healthcare professionals can ensure that they are using a consistent and evidence-based approach to making a diagnosis.

Algorithms can also be used to guide treatment decisions. For instance, an algorithm for managing diabetes might involve setting target blood sugar levels, recommending certain medications or lifestyle changes based on the patient's individual needs, and monitoring the patient's response to treatment over time.

Overall, algorithms are valuable tools in medicine because they help standardize clinical decision-making and ensure that patients receive high-quality care based on the latest scientific evidence.

A computer system is a collection of hardware and software components that work together to perform specific tasks. This includes the physical components such as the central processing unit (CPU), memory, storage devices, and input/output devices, as well as the operating system and application software that run on the hardware. Computer systems can range from small, embedded systems found in appliances and devices, to large, complex networks of interconnected computers used for enterprise-level operations.

In a medical context, computer systems are often used for tasks such as storing and retrieving electronic health records (EHRs), managing patient scheduling and billing, performing diagnostic imaging and analysis, and delivering telemedicine services. These systems must adhere to strict regulatory standards, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States, to ensure the privacy and security of sensitive medical information.

Medical Informatics Computing, also known as Healthcare Informatics or Biomedical Informatics, is the application of computer science and information technology to the field of healthcare and medicine. It involves the development and use of various computational methods, systems, and tools for the acquisition, processing, storage, retrieval, sharing, analysis, and visualization of biomedical data, knowledge, and intelligence. The primary goal is to support and enhance clinical decision-making, patient care, research, education, and management in healthcare organizations.

Medical Informatics Computing encompasses various disciplines such as artificial intelligence, machine learning, natural language processing, data mining, databases, computer networks, human-computer interaction, and bioinformatics. It deals with the integration of diverse health information systems, including electronic health records (EHRs), clinical decision support systems (CDSSs), telemedicine systems, and genomic databases, to provide comprehensive and personalized healthcare services.

Medical Informatics Computing has significant potential in improving patient outcomes, reducing medical errors, increasing efficiency, and reducing healthcare costs. It also plays a crucial role in advancing medical research by enabling large-scale data analysis, hypothesis testing, and knowledge discovery.

I'm sorry for any confusion, but "Microcomputers" is not a term commonly used in medical definitions. Microcomputers are small computers with a microprocessor as the central processing unit. They are widely used in various settings, including healthcare, to perform tasks such as data management, analysis, and patient record keeping. However, the term itself does not have a specific medical connotation. If you have any questions related to technology use in healthcare, I'd be happy to try to help with those!

I'm sorry for any confusion, but "Internet" is a term that pertains to the global network of interconnected computers and servers that enable the transmission and reception of data via the internet protocol (IP). It is not a medical term and does not have a specific medical definition. If you have any questions related to medicine or health, I'd be happy to try to help answer them for you!

Computer-Assisted Instruction (CAI) is a type of educational technology that involves the use of computers to deliver, support, and enhance learning experiences. In a medical context, CAI can be used to teach a variety of topics, including anatomy, physiology, pharmacology, and clinical skills.

CAI typically involves interactive multimedia presentations, simulations, quizzes, and other activities that engage learners and provide feedback on their performance. It may also include adaptive learning systems that adjust the content and pace of instruction based on the learner's abilities and progress.

CAI has been shown to be effective in improving knowledge retention, critical thinking skills, and learner satisfaction in medical education. It can be used as a standalone teaching method or in combination with traditional classroom instruction or clinical experiences.

"Attitude to Computers" is not a medical term or concept, but rather a social science or psychological one. It refers to an individual's feelings, beliefs, and behaviors towards computers and technology in general. This can include things like their comfort level using computers, their perception of the benefits and drawbacks of computer use, and their willingness to learn new technologies.

In some cases, a person's attitude towards computers may be influenced by factors such as their age, education level, work experience, and access to technology. For example, someone who grew up using computers and has had positive experiences with them is likely to have a more favorable attitude than someone who is not familiar with computers or has had negative experiences with them.

It's worth noting that attitudes towards computers can vary widely from person to person, and may change over time as technology evolves and becomes more integrated into daily life. Additionally, while an individual's attitude towards computers may not be a direct medical concern, it can have implications for their overall health and well-being, particularly in terms of their ability to access information, communicate with others, and participate in modern society.

I'm afraid there seems to be a misunderstanding. Programming languages are a field of study in computer science and are not related to medicine. They are used to create computer programs, through the composition of symbols and words. Some popular programming languages include Python, Java, C++, and JavaScript. If you have any questions about programming or computer science, I'd be happy to try and help answer them!

Audiovisual aids are educational tools that utilize both visual and auditory senses to facilitate learning and communication. These aids can include various forms of technology such as projectors, televisions, computers, and mobile devices, as well as traditional materials like posters, charts, and models. In a medical context, audiovisual aids may be used in lectures, presentations, or patient education to help illustrate complex concepts, demonstrate procedures, or provide information in a clear and engaging way. They can be particularly useful for individuals who learn best through visual or auditory means, and can help to improve comprehension and retention of information.

Three-dimensional (3D) imaging in medicine refers to the use of technologies and techniques that generate a 3D representation of internal body structures, organs, or tissues. This is achieved by acquiring and processing data from various imaging modalities such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, or confocal microscopy. The resulting 3D images offer a more detailed visualization of the anatomy and pathology compared to traditional 2D imaging techniques, allowing for improved diagnostic accuracy, surgical planning, and minimally invasive interventions.

In 3D imaging, specialized software is used to reconstruct the acquired data into a volumetric model, which can be manipulated and viewed from different angles and perspectives. This enables healthcare professionals to better understand complex anatomical relationships, detect abnormalities, assess disease progression, and monitor treatment response. Common applications of 3D imaging include neuroimaging, orthopedic surgery planning, cancer staging, dental and maxillofacial reconstruction, and interventional radiology procedures.

Computer peripherals are external devices that can be connected to a computer system to expand its functionality or capabilities. They are called "peripherals" because they are typically located on the periphery of the computer, as opposed to being built into the main computer case or chassis.

There are several types of computer peripherals, including:

Fireflies are rendering artifacts resulting from numerical instabilities in solving the rendering equation. They manifest themselves as anomalously-bright single pixels scattered over parts of the image. Fireflies need to be distinguished from noise (overall graininess in the image), which can be reduced by simply increasing the number of rendering samples (amount of computation) per pixel. Fireflies tend to be harder to get rid of. Fireflies tend to be confined to particular parts of the image, where they are caused by interactions between particular material and lighting settings that only affect certain objects in the scene. Sometimes fireflies can be reduced by various tweaks to renderer settings, for example clamping the maximum intermediate amplitude during pixel calculations, or disabling the calculation of caustics if these are not needed. Another option is application of a despeckle filter as part of rendering post-processing, or manually removing the fireflies with the brush or clone ...
