    Most bioinformatics software has been designed to run on Linux and other Unix-like systems. Unix is different from most desktop operating systems because it makes extensive use of a text-only command-line interface. It can be a challenge to become familiar with the command line, but once a person becomes used to it, there are significant rewards, such as the ability to string a commonly used series of commands together with a script. This appendix will get you started with the command line and other Unix essentials. PMID:26334925

  3. NASTRAN migration to UNIX

    NASA Technical Reports Server (NTRS)

    Chan, Gordon C.; Turner, Horace Q.

    1990-01-01

    COSMIC/NASTRAN, as it is supported and maintained by COSMIC, runs on four main-frame computers - CDC, VAX, IBM and UNIVAC. COSMIC/NASTRAN on other computers, such as CRAY, AMDAHL, PRIME, CONVEX, etc., is available commercially from a number of third party organizations. All these computers, with their own one-of-a-kind operating systems, make NASTRAN machine dependent. The job control language (JCL), the file management, and the program execution procedure of these computers are vastly different, although 95 percent of NASTRAN source code was written in standard ANSI FORTRAN 77. The advantage of the UNIX operating system is that it has no machine boundary. UNIX is becoming widely used in many workstations, mini's, super-PC's, and even some main-frame computers. NASTRAN for the UNIX operating system is definitely the way to go in the future, and makes NASTRAN available to a host of computers, big and small. Since 1985, many NASTRAN improvements and enhancements were made to conform to the ANSI FORTRAN 77 standards. A major UNIX migration effort was incorporated into COSMIC NASTRAN 1990 release. As a pioneer work for the UNIX environment, a version of COSMIC 89 NASTRAN was officially released in October 1989 for DEC ULTRIX VAXstation 3100 (with VMS extensions). A COSMIC 90 NASTRAN version for DEC ULTRIX DECstation 3100 (with RISC) is planned for April 1990 release. Both workstations are UNIX based computers. The COSMIC 90 NASTRAN will be made available on a TK50 tape for the DEC ULTRIX workstations. Previously in 1988, an 88 NASTRAN version was tested successfully on a SiliconGraphics workstation.

  5. Image tools for UNIX

    NASA Technical Reports Server (NTRS)

    Banks, David C.

    1994-01-01

    This talk features two simple and useful tools for digital image processing in the UNIX environment. They are xv and pbmplus. The xv image viewer which runs under the X window system reads images in a number of different file formats and writes them out in different formats. The view area supports a pop-up control panel. The 'algorithms' menu lets you blur an image. The xv control panel also activates the color editor which displays the image's color map (if one exists). The xv image viewer is available through the internet. The pbmplus package is a set of tools designed to perform image processing from within a UNIX shell. The acronym 'pbm' stands for portable bit map. Like xv, the pbm plus tool can convert images from and to many different file formats. The source code and manual pages for pbmplus are also available through the internet. This software is in the public domain.

  6. A UNIX interface to supercomputers

    SciTech Connect

    McBryan, O.A.

    1985-01-01

    We describe a convenient interface between UNIX-based work-stations or minicomputers, and supercomputers such as the CRAY series machines. Using this interface, the user can issue commands entirely on the UNIX system, with remote compilation, loading and execution performed on the supercomputer. The interface is not a remote login interface. Rather the domain of various UNIX utilities such as compilers, archivers and loaders are extended to include the CRAY. The user need know essentially nothing about the CRAY operating system, commands or filename restrictions. Standard UNIX utilities will perform CRAY operations transparently. UNIX command names and arguments are mapped to corresponding CRAY equivalents, suitable options are selected as needed, UNIX directory tree filenames are coerced to allowable CRAY names and all source and output files are automatically transferred between the machines. The primary purpose of the software is to allow the programmer to benefit from the interactive features of UNIX systems including screen editors, software maintenance utilities such as make and SCCS and in general to avail of the large set of UNIX text manipulation features. The interface was designed particularly to support development of very large multi-file programs, possibly consisting of hundreds of files and hundreds of thousands of lines of code. All CRAY source is kept on the work-station. We have found that using the software, the complete program development phase for a large CRAY application may be performed entirely on a work-station.

  7. Common HEP UNIX Environment

    NASA Astrophysics Data System (ADS)

    Taddei, Arnaud

    After it had been decided to design a common user environment for UNIX platforms among HEP laboratories, a joint project between DESY and CERN had been started. The project consists in 2 phases: 1. Provide a common user environment at shell level, 2. Provide a common user environment at graphical level (X11). Phase 1 is in production at DESY and at CERN as well as at PISA and RAL. It has been developed around the scripts originally designed at DESY Zeuthen improved and extended with a 2 months project at CERN with a contribution from DESY Hamburg. It consists of a set of files which are customizing the environment for the 6 main shells (sh, csh, ksh, bash, tcsh, zsh) on the main platforms (AIX, HP-UX, IRIX, SunOS, Solaris 2, OSF/1, ULTRIX, etc.) and it is divided at several "sociological" levels: HEP, site, machine, cluster, group of users and user with some levels which are optional. The second phase is under design and a first proposal has been published. A first version of the phase 2 exists already for AIX and Solaris, and it should be available for all other platforms, by the time of the conference. This is a major collective work between several HEP laboratories involved in the HEPiX-scripts and HEPiX-X11 working-groups.

    Hung, T.; Kunz, P.F.

    1992-09-01

    We describe a code management and distribution system based on tools freely available for the UNIX systems. At the master site, version control is managed with CVS, which is a layer on top of RCS, and distribution is done via NFS mounted file systems. At remote sites, small modifications to CVS provide for interactive transactions with the CVS system at the master site such that remote developers are true peers in the code development process.

  9. Training Records And Information Network UNIX Version

    1996-12-01

    TRAIN-UNIX is used to track training requirements, qualifications, training completion and schedule training, classrooms and instructors. TRAIN-UNIX is a requirements-based system. When the identified training requirements for specific jobs are entered into the system, the employees manager or responsible training person assigns jobs to an employee. TRAIN-UNIX will then assemble an Individual Training Plan (ITP) with all courses required. ITP''s can also be modified to add any special training directed or identified by management, bestmore » business practices, procedures, etc. TRAIN-UNIX also schedules and tracks conferences, seminars, and required reading. TRAIN-UNIX is a secure database system on a server accessible via the network. Access to the user functions (scheduling, data entry, ITP modification etc.) within TRAIN-UNIX are granted by function, as needed, by the system administrator. An additional level of security allows those who access TRAIN-UNIX to only add, modify or view information for the organizations to which they belong. TRAIN-UNIX scheduling function allows network access to scheduling of students. As a function of the scheduling process, TRAIN-UNIX checks to insure that the student is a valid employee, not double booked, and the instructor and classroom are not double booked. TRAIN-UNIX will report pending lapse of courses or qualifications. This ability to know the lapse of training along with built in training requesting function allows the training deliverers to forecast training needs.« less

    The introduction of parallel processors that run a separate copy of Unix on each process has introduced new problems in managing the user`s environment. This paper discusses some generalizations of common Unix commands for managing files (e.g. 1s) and processes (e.g. ps) that are convenient and scalable. These basic tools, just like their Unix counterparts, are text-based. We also discuss a way to use these with a graphical user interface (GUI). Some notes on the implementation are provided. Prototypes of these commands are publicly available.

  12. A secure file manager for UNIX

    SciTech Connect

    DeVries, R.G.

    1990-12-31

    The development of a secure file management system for a UNIX-based computer facility with supercomputers and workstations is described. Specifically, UNIX in its usual form does not address: (1) Operation which would satisfy rigorous security requirements. (2) Online space management in an environment where total data demands would be many times the actual online capacity. (3) Making the file management system part of a computer network in which users of any computer in the local network could retrieve data generated on any other computer in the network. The characteristics of UNIX can be exploited to develop a portable, secure file manager which would operate on computer systems ranging from workstations to supercomputers. Implementation considerations making unusual use of UNIX features, rather than requiring extensive internal system changes, are described, and implementation using the Cray Research Inc. UNICOS operating system is outlined.

  19. UNIX security in a supercomputing environment

    NASA Technical Reports Server (NTRS)

    Bishop, Matt

    1989-01-01

    The author critiques some security mechanisms in most versions of the Unix operating system and suggests more effective tools that either have working prototypes or have been implemented, for example in secure Unix systems. Although no computer (not even a secure one) is impenetrable, breaking into systems with these alternate mechanisms will cost more, require more skill, and be more easily detected than penetrations of systems without these mechanisms. The mechanisms described fall into four classes (with considerable overlap). User authentication at the local host affirms the identity of the person using the computer. The principle of least privilege dictates that properly authenticated users should have rights precisely sufficient to perform their tasks, and system administration functions should be compartmentalized; to this end, access control lists or capabilities should either replace or augment the default Unix protection system, and mandatory access controls implementing multilevel security models and integrity mechanisms should be available. Since most users access supercomputing environments using networks, the third class of mechanisms augments authentication (where feasible). As no security is perfect, the fourth class of mechanism logs events that may indicate possible security violations; this will allow the reconstruction of a successful penetration (if discovered), or possibly the detection of an attempted penetration.

    One of the problems confronting the designers of simulators over the last ten years -- particularly the designers of nuclear plant simulators -- has been how to accommodate the demands of their customers for increasing verisimilitude, especially in the modeling of as-faulted conditions. The demand for the modeling of multiphase multi-component thermal-hydraulics, for example, imposed a requirement that taxed the ingenuity of the simulator software developers. Difficulty was encountered in fitting such models into the existing simulator framework -- not least because the real-time requirement of training simulation imposed severe limits on the minimum time step. In the mid-1980's, two evolutions that had been proceeding for some time culminated in mature products of potentially great utility to simulation. One was the emergence of low-cost work stations featuring not only versatile, object-oriented graphics, but also considerable number-crunching capabilities of their own. The other was the adoption of UNIX as a standard'' operating system common to at least some machines offered by virtually all vendors. As a result, it is possible to design a simulator whose graphics and executive functions are off-loaded to one or more work stations, which are designed to handle such tasks. The number-crunching duties are assigned to another machine, which has been designed expressly for that purpose. This paper deals with such a distributed UNIX-based simulator developed at the Savannah River Laboratory using graphics supplied by Texas A M University under contract to SRL.

    2000-09-29

    This paper presents results obtained by using a method of profiling a user based on the login host, the login time, the command set, and the command set execution time of the profiled user. It is assumed that the user is logging onto a UNIX host on a computer network. The paper concentrates on two areas: short-term and long-term profiling. In short-term profiling the focus is on profiling the user at a given session where user characteristics do not change much. In long-term profiling, the duration of observation is over a much longer period of time. The latter is more challenging because of a phenomenon called concept or profile drift. Profile drift occurs when a user logs onto a host for an extended period of time (over several sessions).

    Devarakonda, Murthy V.; Iyer, Ravishankar K.

    1987-01-01

    Presented is a user-oriented analysis of short term file usage in a 4.2 BSD UNIX environment. The key aspect of this analysis is a characterization of users and files, which is a departure from the traditional approach of analyzing file references. Two characterization measures are employed: accesses-per-byte (combining fraction of a file referenced and number of references) and file size. This new approach is shown to distinguish differences in files as well as users, which cam be used in efficient file system design, and in creating realistic test workloads for simulations. A multi-stage gamma distribution is shown to closely model the file usage measures. Even though overall file sharing is small, some files belonging to a bulletin board system are accessed by many users, simultaneously and otherwise. Over 50% of users referenced files owned by other users, and over 80% of all files were involved in such references. Based on the differences in files and users, suggestions to improve the system performance were also made.

    saved as a library file which represents a generic digraph structure for a class of components. The Generate Model feature can then use library files to generate digraphs for every component listed in the modeling tables, and these individual digraph files can be used in a variety of ways to speed generation of complete digraph models. FEAT contains a preprocessor which performs transitive closure on the digraph. This multi-step algorithm builds a series of phantom bridges, or gates, that allow accurate bi-directional processing of digraphs. This preprocessing can be time-consuming, but once preprocessing is complete, queries can be answered and displayed within seconds. A UNIX X-Windows port of version 3.5 of FEAT, XFEAT, is also available to speed the processing of digraph models created on the Macintosh. FEAT v3.6, which is only available for the Macintosh, has some report generation capabilities which are not available in XFEAT. For very large integrated systems, FEAT can be a real cost saver in terms of design evaluation, training, and knowledge capture. The capability of loading multiple digraphs and schematics into FEAT allows modelers to build smaller, more focused digraphs. Typically, each digraph file will represent only a portion of a larger failure scenario. FEAT will combine these files and digraphs from other modelers to form a continuous mathematical model of the system's failure logic. Since multiple digraphs can be cumbersome to use, FEAT ties propagation results to schematic drawings produced using MacDraw II (v1.1v2 or later) or MacDraw Pro. This makes it easier to identify single and double point failures that may have to cross several system boundaries and multiple engineering disciplines before creating a hazardous condition. FEAT v3.6 for the Macintosh is written in C-language using Macintosh Programmer's Workshop C v3.2. It requires at least a Mac II series computer running System 7 or System 6.0.8 and 32 Bit QuickDraw. It also requires a math

  7. UNIX-based operating systems robustness evaluation

    1996-01-01

    Robust operating systems are required for reliable computing. Techniques for robustness evaluation of operating systems not only enhance the understanding of the reliability of computer systems, but also provide valuable feed- back to system designers. This thesis presents results from robustness evaluation experiments on five UNIX-based operating systems, which include Digital Equipment's OSF/l, Hewlett Packard's HP-UX, Sun Microsystems' Solaris and SunOS, and Silicon Graphics' IRIX. Three sets of experiments were performed. The methodology for evaluation tested (1) the exception handling mechanism, (2) system resource management, and (3) system capacity under high workload stress. An exception generator was used to evaluate the exception handling mechanism of the operating systems. Results included exit status of the exception generator and the system state. Resource management techniques used by individual operating systems were tested using programs designed to usurp system resources such as physical memory and process slots. Finally, the workload stress testing evaluated the effect of the workload on system performance by running a synthetic workload and recording the response time of local and remote user requests. Moderate to severe performance degradations were observed on the systems under stress.

    The FRAC-UNIX computer code provides a two-dimensional simulation of saturated flow and transport in a fractured porous media. The code incorporates a dual permeability approach in which the rock matrix is modeled as rectangular cells and the fractures are represented as discrete elements on the edges and diagonals of the matrix cells. A single head distribution drives otherwise independent flows in the matrix and in the fractures. Steady-state or transient flow of a single-phase fluid may be simulated. Solute or heat transport is simulated by moving imaginary marker particles in the velocity field established by the flow model, under the additional influence of dispersive and diffusive processes. Sparse-matrix techniques are utilized along with a specially developed user interface. The code is installed a CRAY XMP24 Computer using the UNICOS operating system. The initial version of this code, entitled FRACSL, incorporated the same flow and transport models, but used a commercial software package for the numerics and user interface. This report describes the theoretical basis, approach and implementation incorporated in the code; the mechanics of operating the code; several sample problems; and the integration of code development with physical modeling and field testing. The code is fully functional, for most purposes, as shown by the results of an extensive code verification effort. Work remaining consists of refining and adding capabilities needed for several of the code verification problems; relatively simple modifications to extend its application and improve its ease of use; an improvement in the treatment of fracture junctions and correction of an error in calculating buoyancy and concentration for diagonal fractures on a rectangular grid. 42 refs., 28 figs., 5 tabs.

    Many forensic examiners are introduced to UNIX-based forensic utilities when faced with investigating a UNIX-like operating system for the first time. They will use these utilities for this very specific task, because in many cases these tools are the only ones for the given job. For example, at the time of this writing, given a FreeBSD 5.x file system, the author's only choice is to use The Coroner's Toolkit running on FreeBSD 5.x. However, many of the same tools examiners use for the occasional UNIX-like system investigation are extremely capable when a Windows system is the target. Indeed, the Linux operating system itself can prove to be an extremely useful forensics platform with very little use of specialized forensics utilities at all.

    The results of a NASA SBIR project are presented in which CSP-Ariel, a verification system for C programs which use Unix system calls for concurrent programming, interprocess communication, and file input and output, was developed. This project builds on ORA's Ariel C verification system by using the system of Hoare's book, Communicating Sequential Processes, to model concurrency and communication. The system runs in ORA's Clio theorem proving environment. The use of CSP to model Unix concurrency and sketch the CSP semantics of a simple concurrent program is outlined. Plans for further development of CSP-Ariel are discussed. This paper is presented in viewgraph form.

    We performed radio-frequency (RF) skin-depth measurements of antiferromagnetic UNiX compounds (X=Al, Ga, Ge) in magnetic fields up to 60 T and at temperatures between 1.4 to {approx}60 K. Magnetic fields are applied along different crystallographic directions and RF penetration-depth was measured using a tunnel-diode oscillator (TDO) circuit. The sample is coupled to the inductive element of a TDO resonant tank circuit, and the shift in the resonant frequency {Delta}f of the circuit is measured. The UNiX compounds exhibit field-induced magnetic transitions at low temperatures, and those transitions are accompanied by a drastic change in {Delta}f. The results of our skin-depth measurements were compared with previously published B-T phase diagrams for these three compounds.

FEAT will combine these files and digraphs from other modelers to form a continuous mathematical model of the system's failure logic. Since multiple digraphs can be cumbersome to use, FEAT ties propagation results to schematic drawings produced using MacDraw II (v1.1v2 or later) or MacDraw Pro. This makes it easier to identify single and double point failures that may have to cross several system boundaries and multiple engineering disciplines before creating a hazardous condition. FEAT v3.6 for the Macintosh is written in C-language using Macintosh Programmer's Workshop C v3.2. It requires at least a Mac II series computer running System 7 or System 6.0.8 and 32 Bit QuickDraw. It also requires a math

    A new data acquisition system has been developed at the Hahn-Meitner-Institut to handle almost 550 parameters of nuclear physics experiments. The system combines a UNIX host running a portable data buffer router and a VME front-end based on the OS9 real time operating system. Different kinds of pulse analyzers are located in several CAMAC crates which are controlled by the VME system via a VICbus connection. Data readout is performed by means of an ECL daisy chain. Besides controlling CAMAC the main purpose of the VME front-end is event data formatting and histogramming. Using TCP/IP services, the UNIX host receives formatted data packages for data storage and display. During a beam time at the antiproton accelerator LEAR/CERN, the PS208 experiment has accumulated about 100 Gbyte of event data.

  20. A Unix Print Filter for Controlling an HP Laserjet Printer

    SciTech Connect

    Hoffman, F.M.

    1992-01-01

    This report describes a Unix print filter designed to control an Hewlett Packard Laserjet or other printer that uses Hewlett Packard's Printer Control Language (HP-PCL). The filter gives users the ability to control print pitch, orientation, and indentation by using standard flags to the Unix lpr command or multiple entries in the /etc/printcap file and allows both ascii and binary (i.e., graphics and down-loadable fonts) files to be printed. Additionally, the filter provides some accounting capability. The supported print pitch and orientation options are described, as are the different configuration options. The code for the filter is included in Appendix A and sample entries for the /etc/printcap file are included in Appendix B and C.

  1. gLExec: gluing grid computing to the Unix world

    NASA Astrophysics Data System (ADS)

    Groep, D.; Koeroo, O.; Venekamp, G.

    2008-07-01

    The majority of compute resources in todays scientific grids are based on Unix and Unix-like operating systems. In this world, user and user-group management are based around the concepts of a numeric 'user ID' and 'group ID' that are local to the resource. In contrast, grid concepts of user and group management are centered around globally assigned identifiers and VO membership, structures that are independent of any specific resource. At the fabric boundary, these 'grid identities' have to be translated to Unix user IDs. New job submission methodologies, such as job-execution web services, community-deployed local schedulers, and the late binding of user jobs in a grid-wide overlay network of 'pilot jobs', push this fabric boundary ever further down into the resource. gLExec, a light-weight (and thereby auditable) credential mapping and authorization system, addresses these issues. It can be run both on fabric boundary, as part of an execution web service, and on the worker node in a late-binding scenario. In this contribution we describe the rationale for gLExec, how it interacts with the site authorization and credential mapping frameworks such as LCAS, LCMAPS and GUMS, and how it can be used to improve site control and traceability in a pilot-job system.

  2. NQS - NETWORK QUEUING SYSTEM, VERSION 2.0 (UNIX VERSION)

    NASA Technical Reports Server (NTRS)

    Walter, H.

    1994-01-01

    The Network Queuing System, NQS, is a versatile batch and device queuing facility for a single Unix computer or a group of networked computers. With the Unix operating system as a common interface, the user can invoke the NQS collection of user-space programs to move batch and device jobs freely around the different computer hardware tied into the network. NQS provides facilities for remote queuing, request routing, remote status, queue status controls, batch request resource quota limits, and remote output return. This program was developed as part of an effort aimed at tying together diverse UNIX based machines into NASA's Numerical Aerodynamic Simulator Processing System Network. This revision of NQS allows for creating, deleting, adding and setting of complexes that aid in limiting the number of requests to be handled at one time. It also has improved device-oriented queues along with some revision of the displays. NQS was designed to meet the following goals: 1) Provide for the full support of both batch and device requests. 2) Support all of the resource quotas enforceable by the underlying UNIX kernel implementation that are relevant to any particular batch request and its corresponding batch queue. 3) Support remote queuing and routing of batch and device requests throughout the NQS network. 4) Support queue access restrictions through user and group access lists for all queues. 5) Enable networked output return of both output and error files to possibly remote machines. 6) Allow mapping of accounts across machine boundaries. 7) Provide friendly configuration and modification mechanisms for each installation. 8) Support status operations across the network, without requiring a user to log in on remote target machines. 9) Provide for file staging or copying of files for movement to the actual execution machine. To support batch and device requests, NQS v.2 implements three queue types--batch, device and pipe. Batch queues hold and prioritize batch requests

  3. Tools for Administration of a UNIX-Based Network

    LeClaire, Stephen; Farrar, Edward

    2004-01-01

    Several computer programs have been developed to enable efficient administration of a large, heterogeneous, UNIX-based computing and communication network that includes a variety of computers connected to a variety of subnetworks. One program provides secure software tools for administrators to create, modify, lock, and delete accounts of specific users. This program also provides tools for users to change their UNIX passwords and log-in shells. These tools check for errors. Another program comprises a client and a server component that, together, provide a secure mechanism to create, modify, and query quota levels on a network file system (NFS) mounted by use of the VERITAS File SystemJ software. The client software resides on an internal secure computer with a secure Web interface; one can gain access to the client software from any authorized computer capable of running web-browser software. The server software resides on a UNIX computer configured with the VERITAS software system. Directories where VERITAS quotas are applied are NFS-mounted. Another program is a Web-based, client/server Internet Protocol (IP) address tool that facilitates maintenance lookup of information about IP addresses for a network of computers.

  4. Using Unix system auditing for detecting network intrusions

    SciTech Connect

    Christensen, M.J.

    1993-03-01

    Intrusion Detection Systems (IDSs) are designed to detect actions of individuals who use computer resources without authorization as well as legitimate users who exceed their privileges. This paper describes a novel approach to IDS research, namely a decision aiding approach to intrusion detection. The introduction of a decision tree represents the logical steps necessary to distinguish and identify different types of attacks. This tool, the Intrusion Decision Aiding Tool (IDAT), utilizes IDS-based attack models and standard Unix audit data. Since attacks have certain characteristics and are based on already developed signature attack models, experienced and knowledgeable Unix system administrators know what to look for in system audit logs to determine if a system has been attacked. Others, however, are usually less able to recognize common signatures of unauthorized access. Users can traverse the tree using available audit data displayed by IDAT and general knowledge they possess to reach a conclusion regarding suspicious activity. IDAT is an easy-to-use window based application that gathers, analyzes, and displays pertinent system data according to Unix attack characteristics. IDAT offers a more practical approach and allows the user to make an informed decision regarding suspicious activity.

    SciTech Connect

    2004-05-13

    The LHS UNIX Library/Standalone software provides the capability to draw random samples from over 30 distribution types. It performs the sampling by a stratified sampling method called Latin Hypercube Sampling (LHS). Multiple distributions can be sampled simultaneously, with user-specified correlations amongst the input distributions, LHS UNIX Library/ Standalone provides a way to generate multi-variate samples. The LHS samples can be generated either as a callable library (e.g., from within the DAKOTA software framework) or as a standalone capability. LHS UNIX Library/Standalone uses the Latin Hypercube Sampling method (LHS) to generate samples. LHS is a constrained Monte Carlo sampling scheme. In LHS, the range of each variable is divided into non-overlapping intervals on the basis of equal probability. A sample is selected at random with respect to the probability density in each interval, If multiple variables are sampled simultaneously, then values obtained for each are paired in a random manner with the n values of the other variables. In some cases, the pairing is restricted to obtain specified correlations amongst the input variables. Many simulation codes have input parameters that are uncertain and can be specified by a distribution, To perform uncertainty analysis and sensitivity analysis, random values are drawn from the input parameter distributions, and the simulation is run with these values to obtain output values. If this is done repeatedly, with many input samples drawn, one can build up a distribution of the output as well as examine correlations between input and output variables.

  7. UNIX-BASED DATA MANAGEMENT SYSTEM FOR PROPAGATION EXPERIMENTS

    NASA Technical Reports Server (NTRS)

    Kantak, A. V.

    1994-01-01

    This collection of programs comprises The UNIX Based Data Management System for the Pilot Field Experiment (PiFEx) which is an attempt to mimic the Mobile Satellite (MSAT) scenario. The major purposes of PiFEx are to define the mobile communications channels and test the workability of new concepts used to design various components of the receiver system. The results of the PiFex experiment are large amounts of raw data which must be accessed according to a researcher's needs. This package provides a system to manage the PiFEx data in an interactive way. The system not only provides the file handling necessary to retrieve the desired data, but also several FORTRAN programs to generate some standard results pertaining to propagation data. This package assumes that the data file initially generated from the experiment has been already converted from binary to ASCII format. The Data Management system described here consists of programs divided into two categories: those programs that handle the PiFEx generated files and those that are used for number-crunching of these files. Five FORTRAN programs and one UNIX shell script file are used for file manipulation purposes. These activities include: calibration of the acquired data; and parsing of the large data file into datasets concerned with different aspects of the experiment such as the specific calibrated propagation data, dynamic and static loop error data, statistical data, and temperature and spatial data on the hardware used in the experiment. The five remaining FORTRAN programs are used to generate usable information about the data. Signal level probability, probability density of the signal fitting the Rician density function, frequency of the data's fade duration, and the Fourier transform of the data can all be generated from these data manipulation programs. In addition, a program is provided which generates a downloadable file from the signal levels and signal phases files for use with the plotting routine

    1994-01-01

    GEMPAK is a general meteorological software package developed at NASA/Goddard Space Flight Center. It includes programs to analyze and display surface, upper-air, and gridded data, including model output. There are very general programs to list, edit, and plot data on maps, to display profiles and time series, to draw and fill contours, to draw streamlines, to plot symbols for clouds, sky cover, and pressure tendency, and draw cross sections in the case of gridded data and sounding data. In addition, there are Barnes objective analysis programs to grid surface and upper-air data. The programs include the capabilities to derive meteorological parameters from those found in the dataset, to perform vertical interpolations of sounding data to different coordinate systems, and to compute an extensive set of gridded diagnostic quantities by specifying various nested combinations of scalars and vector arithmetic, algebraic, and differential operators. The GEMPAK 5.1 graphics/transformation subsystem, GEMPLT, provides device-independent graphics. GEMPLT also has the capability to display output in a variety of map projections or overlaid on satellite imagery. GEMPAK 5.1 is written in FORTRAN 77 and C-language and has been implemented on VAX computers under VMS and on computers running the UNIX operating system. During installation and normal use, this package occupies approximately 100Mb of hard disk space. The UNIX version of GEMPAK includes drivers for several graphic output systems including MIT's X Window System (X11,R4), Sun GKS, PostScript (color and monochrome), Silicon Graphics, and others. The VMS version of GEMPAK also includes drivers for several graphic output systems including PostScript (color and monochrome). The VMS version is delivered with the object code for the Transportable Applications Environment (TAE) program, version 4.1 which serves as a user interface. A color monitor is recommended for displaying maps on video display devices. Data for rendering

    This document is a reference guide for the UNIX Library/Standalone version of the Latin Hypercube Sampling Software. This software has been developed to generate Latin hypercube multivariate samples. This version runs on Linux or UNIX platforms. This manual covers the use of the LHS code in a UNIX environment, run either as a standalone program or as a callable library. The underlying code in the UNIX Library/Standalone version of LHS is almost identical to the updated Windows version of LHS released in 1998 (SAND98-0210). However, some modifications were made to customize it for a UNIX environment and as a library that is called from the DAKOTA environment. This manual covers the use of the LHS code as a library and in the standalone mode under UNIX.

    1993-02-01

    Highly reliable and available systems are critical to the airline industry. However, most off-the-shelf computer operating systems and hardware do not have built-in fault tolerant mechanisms, the UNIX workstation is one example. In this research effort, we have developed a rule-based Expert System (ES) to monitor, command, and control a UNIX workstation system with hot-standby redundancy. The ES on each workstation acts as an on-line system administrator to diagnose, report, correct, and prevent certain types of hardware and software failures. If a primary station is approaching failure, the ES coordinates the switch-over to a hot-standby secondary workstation. The goal is to discover and solve certain fatal problems early enough to prevent complete system failure from occurring and therefore to enhance system reliability and availability. Test results show that the ES can diagnose all targeted faulty scenarios and take desired actions in a consistent manner regardless of the sequence of the faults. The ES can perform designated system administration tasks about ten times faster than an experienced human operator. Compared with a single workstation system, our hot-standby redundancy system downtime is predicted to be reduced by more than 50 percent by using the ES to command and control the system.

    Database management is an increasingly important part of astronomical data analysis. Astronomers need easy and convenient ways of storing, editing, filtering, and retrieving data about data. Commercial databases do not provide good solutions for many of the everyday and informal types of database access astronomers need. The Starbase database system with simple data file formatting rules and command line data operators has been created to answer this need. The system includes a complete set of relational and set operators, fast search/index and sorting operators, and many formatting and I/O operators. Special features are included to enhance the usefulness of the database when manipulating astronomical data. The software runs under UNIX, MSDOS and IRAF.

    1986-01-01

    This paper describes a project to evaluate the feasibility of using commercial off-the-shelf hardware and the UNIX operating system, to implement a real-time control and monitor system. A functional subset of the Checkout, Control and Monitor System was chosen as the test bed for the project. The project consists of three separate architecture implementations: a local area bus network, a star network, and a central host. The motivation for this project stemmed from the need to find a way to implement real-time systems, without the cost burden of developing and maintaining custom hardware and unique software. This has always been accepted as the only option because of the need to optimize the implementation for performance. However, with the cost/performance of today's hardware, the inefficiencies of high-level languages and portable operating systems can be effectively overcome.

    1994-01-01

    An R&D division of the National Library of Medicine has developed a prototype system for automated document image delivery as an adjunct to the labor-intensive manual interlibrary loan service of the library. The document image archive is implemented by a PC controlled bank of optical disk drives which use 12 inch WORM platters containing bitmapped images of over 200,000 pages of medical journals. Following three years of routine operation which resulted in serving patrons with articles both by mail and fax, an effort is underway to relocate the storage environment from the DOS-based system to a UNIX-based jukebox whose magneto-optical erasable 5 1/4 inch platters hold the images. This paper describes the deficiencies of the current storage system, the design issues of modifying several modules in the system, the alternatives proposed and the tradeoffs involved.

    loads may be either tensile or compressive. Several standardized aircraft flight-load histories, such as TWIST, Mini-TWIST, FALSTAFF, Inverted FALSTAFF, Felix and Gaussian, are included as options. FASTRAN II also includes two other methods that will help the user input spectrum load histories. The two methods are: (1) a list of stress points, and (2) a flight-by-flight history of stress points. Examples are provided in the user manual. Developed as a research program, FASTRAN II has successfully predicted crack growth in many metallic materials under various aircraft spectrum loading. A computer program DKEFF which is a part of the FASTRAN II package was also developed to analyze crack growth rate data from laboratory specimens to obtain the effective stress-intensity factor against crack growth rate relations used in FASTRAN II. FASTRAN II is written in standard FORTRAN 77. It has been successfully compiled and implemented on Sun4 series computers running SunOS and on IBM PC compatibles running MS-DOS using the Lahey F77L FORTRAN compiler. Sample input and output data are included with the FASTRAN II package. The UNIX version requires 660K of RAM for execution. The standard distribution medium for the UNIX version (LAR-14865) is a .25 inch streaming magnetic tape cartridge in UNIX tar format. It is also available on a 3.5 inch diskette in UNIX tar format.

  9. Predictability of process resource usage: A measurement-based study of UNIX

    NASA Technical Reports Server (NTRS)

    Devarakonda, Murthy V.; Iyer, Ravishankar K.

    1987-01-01

    A probabilistic scheme is developed to predict process resource usage in UNIX. Given the identity of the program being run, the scheme predicts CPU time, file I/O, and memory requirements of a process at the beginning of its life. The scheme uses a state-transition model of the program's resource usage in its past executions for prediction. The states of the model are the resource regions obtained from an off-line cluster analysis of processes run on the system. The proposed method is shown to work on data collected from a VAX 11/780 running 4.3 BSD UNIX. The results show that the predicted values correlate well with the actual. The correlation coefficient between the predicted and actual values of CPU time is 0.84. Errors in prediction are mostly small. Some 82% of errors in CPU time prediction are less than 0.5 standard deviations of process CPU time.

  11. A real-time diagnostic and performance monitor for UNIX. M.S. Thesis

    NASA Technical Reports Server (NTRS)

    Dong, Hongchao

    1992-01-01

    There are now over one million UNIX sites and the pace at which new installations are added is steadily increasing. Along with this increase, comes a need to develop simple efficient, effective and adaptable ways of simultaneously collecting real-time diagnostic and performance data. This need exists because distributed systems can give rise to complex failure situations that are often un-identifiable with single-machine diagnostic software. The simultaneous collection of error and performance data is also important for research in failure prediction and error/performance studies. This paper introduces a portable method to concurrently collect real-time diagnostic and performance data on a distributed UNIX system. The combined diagnostic/performance data collection is implemented on a distributed multi-computer system using SUN4's as servers. The approach uses existing UNIX system facilities to gather system dependability information such as error and crash reports. In addition, performance data such as CPU utilization, disk usage, I/O transfer rate and network contention is also collected. In the future, the collected data will be used to identify dependability bottlenecks and to analyze the impact of failures on system performance.

    A new method is presented for handling data resulting from Mobile Satellite propagation experiments such as the Pilot Field Experiment (PiFEx) conducted by JPL. This method uses the UNIX operating system and C programming language. The data management system is implemented on a VAX minicomputer. The system automatically divides the large data file housing data from various experiments under a predetermined format into various individual files containing data from each experiment. The system also has a number of programs written in C and FORTRAN languages to allow the researcher to obtain meaningful quantities from the data at hand.

    1993-01-01

    In cooperation with the NASA Crustal Dynamics Project initiative placing workstation computers at each of its laser ranging stations to handle data filtering and normalpointing, MLRS personnel have developed a new generation of software to provide the same services for the lunar laser ranging data type. The Unix operating system and X windows/Motif provides an environment for both batch and interactive filtering and normalpointing as well as prediction calculations. The goal is to provide a transportable and maintainable data reduction environment. This software and some sample displays are presented. that the lunar (or satellite) datacould be processed on one computer while data was taken on the other. The reduction of the data was totally interactive and in no way automated. In addition, lunar predictions were produced on-site, another first in the effort to down-size historically mainframe-based applications. Extraction of earth rotation parameters was at one time attempted on site in near-realtime. In 1988, the Crustal Dynamics Project SLR Computer Panel mandated the installation of Hewlett-Packard 9000/360 Unix workstations at each NASA-operated laser ranging station to relieve the aging controller computers of much of their data and communications handling responsibility and to provide on-site data filtering and normal pointing for a growing list of artificial satellite targets. This was seen by MLRS staff as an opportunity to provide a better lunar data processing environment as well.

  14. CLIPS 6.0 - C LANGUAGE INTEGRATED PRODUCTION SYSTEM, VERSION 6.0 (UNIX VERSION)

    COOL (that is, a rule can pattern match on objects created using COOL). CLIPS 6.0 provides the capability to define functions, overloaded functions, and global variables interactively. In addition, CLIPS can be embedded within procedural code, called as a subroutine, and integrated with languages such as C, FORTRAN and Ada. CLIPS can be easily extended by a user through the use of several well-defined protocols. CLIPS provides several delivery options for programs including the ability to generate stand alone executables or to load programs from text or binary files. CLIPS 6.0 provides support for the modular development and execution of knowledge bases with the defmodule construct. CLIPS modules allow a set of constructs to be grouped together such that explicit control can be maintained over restricting the access of the constructs by other modules. This type of control is similar to global and local scoping used in languages such as C or Ada. By restricting access to deftemplate and defclass constructs, modules can function as blackboards, permitting only certain facts and instances to be seen by other modules. Modules are also used by rules to provide execution control. The CRSV (Cross-Reference, Style, and Verification) utility included with previous version of CLIPS is no longer supported. The capabilities provided by this tool are now available directly within CLIPS 6.0 to aid in the development, debugging, and verification of large rule bases. COSMIC offers four distribution versions of CLIPS 6.0: UNIX (MSC-22433), VMS (MSC-22434), MACINTOSH (MSC-22429), and IBM PC (MSC-22430). Executable files, source code, utilities, documentation, and examples are included on the program media. All distribution versions include identical source code for the command line version of CLIPS 6.0. This source code should compile on any platform with an ANSI C compiler. Each distribution version of CLIPS 6.0, except that for the Macintosh platform, includes an executable for the

    1985-01-01

    A computer aided design (CAD) system that is being used at the Jet Propulsion Laboratory for the design of custom and semicustom very large scale integrated (VLSI) chips is described. The system consists of a Digital Equipment Corporation VAX computer with the UNIX operating system and a collection of software tools for the layout, simulation, and verification of microcircuits. Most of these tools were written by the academic community and are, therefore, available to JPL at little or no cost. Some small pieces of software have been written in-house in order to make all the tools interact with each other with a minimal amount of effort on the part of the designer.

    1989-09-01

    Although networks of computers have become common, it is still not easy to experiment with their use for distributed computing. One problem is that languages for distributed programming are not yet commonly available, although some exceptions, such as SR, have been developed at universities. Implementing such a language is a major task. This article describes a prototype distributed programming project that provides cheap distributed computing in a form that facilitates experimenting with techniques for shared computations. It is implemented on a network of workstations sharing access to a file server, and can be used wherever several computers are loosely coupled with access to some common resources. It requires only that the network implementation include an application interface that provides basic message-passing facilities. The authors demonstrate its usefulness by describing a parallel version of the UNIX make tool that compiles and links a number of program modules with various dependency relations. They also discuss briefly some other applications.

    This paper describes our technical approach to developing and delivering Unix host- and network-based security products to meet the increasing challenges in information security. Today`s global ``Infosphere`` presents us with a networked environment that knows no geographical, national, or temporal boundaries, and no ownership, laws, or identity cards. This seamless aggregation of computers, networks, databases, applications, and the like store, transmit, and process information. This information is now recognized as an asset to governments, corporations, and individuals alike. This information must be protected from misuse. The Security Profile Inspector (SPI) performs static analyses of Unix-based clients and servers to check on their security configuration. SPI`s broad range of security tests and flexible usage options support the needs of novice and expert system administrators alike. SPI`s use within the Department of Energy and Department of Defense has resulted in more secure systems, less vulnerable to hostile intentions. Host-based information protection techniques and tools must also be supported by network-based capabilities. Our experience shows that a weak link in a network of clients and servers presents itself sooner or later, and can be more readily identified by dynamic intrusion detection techniques and tools. The Network Intrusion Detector (NID) is one such tool. NID is designed to monitor and analyze activity on an Ethernet broadcast Local Area Network segment and produce transcripts of suspicious user connections. NID`s retrospective and real-time modes have proven invaluable to security officers faced with ongoing attacks to their systems and networks.

    A control system for high-throughput protein crystallography experiments has been developed based on a multilevel secure (SSL v2/v3) UNIX socket under the Linux operating system. Main features of protein crystallography experiments (purification, crystallization, loop preparation, data collecting, data processing) are dealt with by the software. All information necessary to perform protein crystallography experiments is stored (except raw X-ray data, that are stored in Network File Server) in a relational database (MySQL). The system consists of several servers and clients. TCP/IP secure UNIX sockets with four predefined behaviors [(a) listening to a request followed by a reply, (b) sending a request and waiting for a reply, (c) listening to a broadcast message, and (d) sending a broadcast message] support communications between all servers and clients allowing one to control experiments, view data, edit experimental conditions and perform data processing remotely. The usage of the interface software is well suited for developing well organized control software with a hierarchical structure of different software units (Gaponov et al., 1998), which will pass and receive different types of information. All communication is divided into two parts: low and top levels. Large and complicated control tasks are split into several smaller ones, which can be processed by control clients independently. For communicating with experimental equipment (beamline optical elements, robots, and specialized experimental equipment etc.), the STARS server, developed at the Photon Factory, is used (Kosuge et al., 2002). The STARS server allows any application with an open socket to be connected with any other clients that control experimental equipment. Majority of the source code is written in C/C++. GUI modules of the system were built mainly using Glade user interface builder for GTK+ and Gnome under Red Hat Linux 7.1 operating system. PMID:14646123

    Wernicke encephalopathy (or Wernicke-Korsakoff encephalopathy) is a rarely diagnosed neurological disorder, which is caused by vitamin B1 deficiency. In the classical form it is characterized by a typical triad (confusion, oculomotor disturbance and ataxia), however, in the majority of the cases only confusion is present. It can be frequently observed in subjects with chronic alcohol consumption, but it may accompany different pathological states of which end stage malignant diseases are the most importants, where confusion may have different backgrounds. The authors present the case of an old male patient with advanced gastric cancer recognised and treated vitamin B1 deficiency, and they draw attention to difficulties of the diagnosis of Wernicke's disease.

    The Science Planning and Scheduling Team (SPST) of the Space Telescope Science Institute (STScI) has historically operated exclusively under VMS. Due to diminished support for VMS-based platforms at STScI, SPST is in the process of transitioning to Unix operations. In the summer of 1999, SPST selected Python as the primary scripting language for the operational tools and began translation of the VMS DCL code. As of October 2000, SPST has installed a utility library of 16 modules consisting of 8000 lines of code and 80 Python tools consisting of 13000 lines of code. All tasks related to calendar generation have been switched to Unix operations. Current work focuses on translating the tools used to generate the Science Mission Specifications (SMS). The software required to generate the Mission Schedule and Command Loads (PASS), maintained by another team at STScI, will take longer to translate than the rest of the SPST operational code. SPST is planning on creating tools to access PASS from Unix in the short term. We are on schedule to complete the work needed to fully transition SPST to Unix operations (while remotely accessing PASS on VMS) by the fall of 2001.

TURB3D is a modification of PLOT3D which is used for viewing CFD simulations of incompressible turbulent flow. Input flow data consists of pressure, velocity and vorticity. Typical quantities to plot include local fluctuations in flow quantities and turbulent production terms, plotted in physical or wall units. PLOT3D/TURB3D includes both TURB3D and PLOT3D because the operation of TURB3D is identical to PLOT3D, and there is no additional sample data or printed documentation for TURB3D. Graphical capabilities of PLOT3D version 3.6b+ vary among the implementations available through COSMIC. Customers are encouraged to purchase and carefully review the PLOT3D manual before ordering the program for a specific computer and graphics library. There is only one manual for use with all implementations of PLOT3D, and although this manual generally assumes that the Silicon Graphics Iris implementation is being used, informative comments concerning other implementations appear throughout the text. With all implementations, the visual representation of the object and flow field created by PLOT3D consists of points, lines, and polygons. Points can be represented with dots or symbols, color can be used to denote data values, and perspective is used to show depth. Differences among implementations impact the program's ability to use graphical features that are based on 3D polygons, the user's ability to manipulate the graphical displays, and the user's ability to obtain alternate forms of output.

  9. Long-Term file activity patterns in a UNIX workstation environment

    Gibson, Timothy J.; Miller, Ethan L.

    1998-01-01

    As mass storage technology becomes more affordable for sites smaller than supercomputer centers, understanding their file access patterns becomes crucial for developing systems to store rarely used data on tertiary storage devices such as tapes and optical disks. This paper presents a new way to collect and analyze file system statistics for UNIX-based file systems. The collection system runs in user-space and requires no modification of the operating system kernel. The statistics package provides details about file system operations at the file level: creations, deletions, modifications, etc. The paper analyzes four months of file system activity on a university file system. The results confirm previously published results gathered from supercomputer file systems, but differ in several important areas. Files in this study were considerably smaller than those at supercomputer centers, and they were accessed less frequently. Additionally, the long-term creation rate on workstation file systems is sufficiently low so that all data more than a day old could be cheaply saved on a mass storage device, allowing the integration of time travel into every file system.

    1995-10-01

    The increased use of UNIX based computer systems for machine control, data handling and analysis has greatly enhanced the operating scenarios and operating efficiency of the DRI-D tokamak. This paper will describe some of these UNIX systems and their specific uses. These include the plasma control system, the electron cyclotron heating control system, the analysis of electron temperature and density measurements and the general data acquisition system (which is collecting over 130 Mbytes of data). The speed and total capability of these systems has dramatically affected the ability to operate DIII-D. The improved operating scenarios include better plasma shape control due to the more thorough MHD calculations done between shots and the new ability to see the time dependence of profile data as it relates across different spatial locations in the tokamak. Other analysis which engenders improved operating abilities will be described.

    1994-01-01

    The DET/MPS programs model and simulate the Direct Energy Transfer and Multimission Spacecraft Modular Power System in order to aid both in design and in analysis of orbital energy balance. Typically, the DET power system has the solar array directly to the spacecraft bus, and the central building block of MPS is the Standard Power Regulator Unit. DET/MPS allows a minute-by-minute simulation of the power system's performance as it responds to various orbital parameters, focusing its output on solar array output and battery characteristics. While this package is limited in terms of orbital mechanics, it is sufficient to calculate eclipse and solar array data for circular or non-circular orbits. DET/MPS can be adjusted to run one or sequential orbits up to about one week, simulated time. These programs have been used on a variety of Goddard Space Flight Center spacecraft projects. DET/MPS is written in FORTRAN 77 with some VAX-type extensions. Any FORTRAN 77 compiler that includes VAX extensions should be able to compile and run the program with little or no modifications. The compiler must at least support free-form (or tab-delineated) source format and 'do do-while end-do' control structures. DET/MPS is available for three platforms: GSC-13374, for DEC VAX series computers running VMS, is available in DEC VAX Backup format on a 9-track 1600 BPI tape (standard distribution) or TK50 tape cartridge; GSC-13443, for UNIX-based computers, is available on a .25 inch streaming magnetic tape cartridge in UNIX tar format; and GSC-13444, for Macintosh computers running AU/X with either the NKR FORTRAN or AbSoft MacFORTRAN II compilers, is available on a 3.5 inch 800K Macintosh format diskette. Source code and test data are supplied. The UNIX version of DET requires 90K of main memory for execution. DET/MPS was developed in 1990.

    1987-12-01

    This paper describes the design and implementation of the Air Force Institute of Technology's (AFIT's) UNIX-based VHDL Analyzer. The purpose of this tool is to facilitate the introduction of VHDL into the academic environment, which may not be able to use the Department of Defense's VMS-based software. This research emphasized two areas: the criteria for a production-quality software product and the design of an efficient Intermediate Representation (IR) that serves as an interface between the Analyzer and other tools in the AFIT VHDL Environment (AVE). Background on other UNIX VHDL analyzers, as well as other IRs, was presented. A two-part IR, based on Dallen's Patois hardware description language and named the VHDL Intermediate Access (VIA), was designed, and examples were given that illustrate its use. Test results showed that the Analyzer passed over 75 percent of the conformance tests from the VHDL VMS Analyzer Test Suite and performed well in the areas of compile time, memory usage, and disk usage. Recommendations for future research include adding user options to the Analyzer and implementing a design library for VHDL designs.

    Benavente, Javier E.; Luce, Norris R.

    1989-01-01

    Demands for nonlinear time history simulations of large, flexible multibody dynamic systems has created a need for efficient interfaces between finite-element modeling programs and time-history simulations. One such interface, TREEFLX, an interface between NASTRAN and TREETOPS, a nonlinear dynamics and controls time history simulation for multibody structures, is presented and demonstrated via example using the proposed Space Station Mobile Remote Manipulator System (MRMS). The ability to run all three programs (NASTRAN, TREEFLX and TREETOPS), in addition to other programs used for controller design and model reduction (such as DMATLAB and TREESEL, both described), under a UNIX Workstation environment demonstrates the flexibility engineers now have in designing, developing and testing control systems for dynamically complex systems.

  2. Mechanical surface waves accompany action potential propagation.

    El Hady, Ahmed; Machta, Benjamin B

    2015-01-01

    Many diverse studies have shown that a mechanical displacement of the axonal membrane accompanies the electrical pulse defining the action potential (AP). We present a model for these mechanical displacements as arising from the driving of surface wave modes in which potential energy is stored in elastic properties of the neuronal membrane and cytoskeleton while kinetic energy is carried by the axoplasmic fluid. In our model, these surface waves are driven by the travelling wave of electrical depolarization characterizing the AP, altering compressive electrostatic forces across the membrane. This driving leads to co-propagating mechanical displacements, which we term Action Waves (AWs). Our model allows us to estimate the shape of the AW that accompanies any travelling wave of voltage, making predictions that are in agreement with results from several experimental systems. Our model can serve as a framework for understanding the physical origins and possible functional roles of these AWs. PMID:25819404

    We report a case of ocular myasthenia gravis (MG) accompanied by anosmia. A 76-year-old man had idiopathic anosmia of 2-year duration. Four months before consultation, he began to have drooping in the right upper eyelid along with muscle soreness, distension, and pain in the nape. His tongue was dark-red with a thin and white coating; his pulse was wiry and slippery. According to Traditional Chinese Medicine, eyelid drooping and anosmia are the main signs of liver constraint and spleen deficiency. In Western Medicine, the diagnosis was ocular MG and idiopathic anosmia. Our patient, along with the literature, suggests that anosmia may be an early symptom before MG. MG accompanied by anosmia could be a special subtype of MG according to antibody production and symptoms. PMID:26946629

    Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome. PMID:25506011

    At a time when the informatics and telecommunications industries are looking for new markets to exploit in relation, for example, to the emerging ISDN and broadband communications networks, there is a need to create a broad consensus in Europe by bringing together systematically the relevant industries including telecom service providers, health care providers, insurance organisations, standardisation experts and policy makers. The aim of the ACOSTA (Consensus Formation and Standardisation Promotion) Accompanying Measure is the creation of more general awareness of the relevant environment among all the parties, better specification of common requirements and options taking better account of the real needs of the users, and enlargement of the common market in health care telematics.

Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

    1933-01-01

    A brief historical and descriptive account of solid injection is followed by a detailed review of the available theoretical and experimental data that seem to throw light on the mechanism of this form of atomization. It is concluded that this evidence indicates that (1) the atomization accompanying solid injection occurs at the surface of the liquid after it issues as a solid stream from the orifice; and (2) that such atomization has a mechanism physically identical with the atomization which takes place in an air stream, both being due merely to the formation, at the gas-liquid interface, of fine ligaments under the influence of the relative motion of gas and liquid, and to their collapse, under the influence of surface tension, to form the drops in the spray.

  10. [How to accompany a suicidal patient].

    PubMed

    Dorfman Lerner, B

    1986-06-01

    In this paper the author offers the prospective T.C. an orientation for the treatment of patients who have intended suicide. After examining general questions such as who and when people commit suicide, she presents an "Assessment of self-destructive potentiality" by Tabachnik & Farberow as a guide to the best prevention of the suicidal act. The metapsychological view of Freud as regards the repressed homicidal motivation in suicide is complemented by the views of Garma and Abadi. In respect to the process of accompaniment in these cases, the author suggests the appearance of four phases (simultaneous or in succession) that are: 1. the presence and the regard in which what is important for the patient is that the T.C. is there and affectionately regards him; 2. the listening, in which the T.C. provides facilities for the patient to speak; 3. the key word, in which "I comprehend" is the privileged T.C. expression; and 4. the dialogue. Within phase 3. discrimination can be made between different psycholinguistic aspects of the key expression, such as: a) its constituting aspects; b) its catarctic or economic aspect; c) its meaning a recognition of the patient's identity; and d) the emergence of hope. Also, as suicide is the end point of different psychopathologies, a brief indication of possible T.C. responses is given. In all these, the principal aim is to help the patient to elaborate a new life project. A clinical successful example shows how three T.C. were included in the treatment of a suicidal patient to accompany her in the recognition and tolerance of her own and others' aggressive feelings. Some philosophical considerations are added. PMID:3788628

    1999-01-01

    We examined the mechanism of cyst formation in extra-axial tumours in the central nervous system (CNS). Cyst fluid, cerebrospinal fluid (CSF) and blood plasma were analysed in eight patients with nine peritumoral cysts: four with meningiomas, two with intracranial and two spinal intradural schwannomas. Measuring concentrations of various proteins [albumin, immunoglobulin G (IgG), IgA, alpha 2-macroglobulin and IgM] in cyst fluid, CSF and blood plasma provides insight into the state of the semipermeability of the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier. Peritumoral cysts accompanying intra-axial brain tumours are the end result of disruption of the BBB and oedema formation. Unlike intra-axial tumours which lie embedded within nervous tissue, extra-axial tumours tend to be separated from nervous tissue by arachnoid and pia mater. High concentrations of proteins were measured in the cyst fluid, approaching blood plasma levels, suggesting a local barrier disruption, and passage across the arachnoid, pia mater and cortical/medullary layer into the CNS parenchyma, leaving the protein concentrations of CSF practically unchanged. We confirmed that very high concentrations of protein are to be found in tumour cysts, plasma proteins forming almost 90% of the total protein in the cyst. We review current hypotheses on the pathogenesis of cysts accompanying neoplasms, particularly meningiomas and schwannomas, and conclude that the majority of proteins in cyst fluid in extra-axial, intradural meningiomas and schwannomas are plasma proteins. This provides a strong argument for pathogenesis of extra-axial intradural tumour cysts in favour of leakage of plasma proteins out of the tumour vessels into the nervous tissue. PMID:9987761

    The Science and Mission Scheduling Branch (SMSB) of the Space Telescope Science Institute (STScI) historically operated exclusively under VMS. Due to diminished support for VMS-based platforms at STScI, SMSB recently transitioned to Unix operations. No additional resources were available to the group; the project was SMSB's to design, develop, and implement. Early decisions included the choice of Python as the primary scripting language; adoption of Object-Oriented Design in the development of base utilities; and the development of a Python utility to interact directly with the Sybase database. The project was completed in January 2004 with the implementation of a GUI to generate the Command Loads that are uplinked to HST. The current tool suite consists of 31 utilities and 271 tools comprising over 60,000 lines of code. In this paper, we summarize the decision-making process used to determine the primary scripting language, database interface, and code management library. We also describe the finished product and summarize lessons learned along the way to completing the project.

    2008-10-01

    The Jefferson Lab Accelerator Controls Environment (ACE) was predominantly based on the HP-UX Unix platform from 1987 through the summer of 2004. During this period the Accelerator Machine Control Center (MCC) underwent a major renovation which included introducing Redhat Enterprise Linux machines, first as specialized process servers and then gradually as general login servers. As computer programs and scripts required to run the accelerator were modified, and inherent problems with the HP-UX platform compounded, more development tools became available for use with Linux and the MCC began to be converted over. In May 2008 the last HP-UX Unix login machine was removed from the MCC, leaving only a few Unix-based remote-login servers still available. This presentation will explore the process of converting an operational Control Room environment from the HP-UX to Linux platform as well as the many hurdles that had to be overcome throughout the transition period (including a discussion of

  14. Mechanical Surface Waves Accompany Action Potential Propagation

    2015-03-01

    The action potential (AP) is the basic mechanism by which information is transmitted along neuronal axons. Although the excitable nature of axons is understood to be primarily electrical, many experimental studies have shown that a mechanical displacement of the axonal membrane co-propagates with the electrical signal. While the experimental evidence for co-propagating mechanical waves is diverse and compelling, there is no consensus for their physical underpinnings. We present a model in which these mechanical displacements arise from the driving of mechanical surface waves, in which potential energy is stored in elastic deformations of the neuronal membrane and cytoskeleton while kinetic energy is stored in the movement of the axoplasmic fluid. In our model these surface waves are driven by the traveling wave of electrical depolarization that characterizes the AP, altering the electrostatic forces across the membrane as it passes. Our model allows us to predict the shape of the displacement that should accompany any traveling wave of voltage, including the well-characterized AP. We expect our model to serve as a framework for understanding the physical origins and possible functional roles of these AWs in neurobiology. See Arxiv/1407.7600

    Good's syndrome is an immunodeficiency disease involving thymoma accompanied by hypogammaglobulinemia. We encountered a case of Good's syndrome accompanied by agranulocytosis that followed a rapid clinical course. A 72-year-old man visited our hospital with a two-week history of a sore throat. Candida albicans was detected in the pharynx, and hypogammaglobulinemia was detected in addition to granulocytopenia. The patient subsequently developed septic shock and followed a rapid clinical course which ended in death. Good's syndrome with agranulocytosis was diagnosed at autopsy. Good's syndrome accompanied by agranulocytosis can follow a rapid clinical course and some cases remain asymptomatic until old age. Its prompt treatment is crucial. PMID:26935379

  9. Is hydroxyapatite a reliable fixation option in unicompartmental knee arthroplasty? A 5- to 13-year experience with the hydroxyapatite-coated unix prosthesis.

    PubMed

    Epinette, Jean-Alain; Manley, Michael T

    2008-10-01

    Hydroxyapatite-coated unicompartmental knee arthroplasty (UKA) is a debatable approach to unicompartmental knee arthritis because UKA isoften viewed as a short-term solution, at best, fora condition that will eventually require a total knee arthroplasty (TKA). Unicompartmental knee arthroplasty is a more technically demanding procedure than TKA, and appropriate patient selection, careful surgical technique, and correct choice of implant geometry are all critical components to its success. A fundamental issue surrounding UKA is whether hydroxyapatite-coated unicompartmental components can provide a long-term solution to unicondylar arthritis. We address this issue in the current study, which is based on a prospective series of 125 hydroxyapatite-coated Unix knee prostheses implanted consecutively between 1994 and 2002, with a 5-year minimum follow-up and a 13-year maximum follow-up. The results of our study indicate that uncemented hydroxyapatite-coated UKA can be successful in the long term. PMID:18979933

    Diphallus (penile duplication) is very rare and seen once every 5.5 million births. It can be isolated, but is usually accompanied by other congenital anomalies. Previous studies have reported many concurrent anomalies, such as bladder extrophy, cloacal extrophy, duplicated bladder, scrotal abnormalities, hypospadias, separated symphysis pubis, intestinal anomalies and imperforate anus; no penile duplication case accompanied by omphalocele has been reported. We present the surgical management of a patient with multiple anomalies, including complete penile duplication, hypo-gastric omphalocele and extrophic rectal duplication. PMID:25408817

    Selective plasma exchange is a blood purification therapy in which simple plasma exchange is performed using a selective membrane plasma separator (pore size of 0.03 µm). Seven critically ill patients accompanied with thrombocytopenia were treated with selective plasma exchange using fresh frozen plasma. The total bilirubin levels and prothrombin time international normalized ratios decreased significantly after treatment. The total protein, albumin, and fibrinogen levels increased significantly after treatment. Selective plasma exchange may be a useful blood purification therapy for removing causal substances and retaining coagulation factors in patients accompanied with thrombocytopenia. PMID:27523072

    We report a case of idiopathic cerebral hypertrophic pachymeningitis accompanying neuromyelitis optica spectrum disorder. No other identifiable cause of pachymeningitis was detected. Corticosteroid therapy was effective for both diseases. Hypertrophic pachymeningitis is closely related to autoimmune inflammatory disease of the central nervous system. This case supports the hypothesis that hypertrophic pachymeningitis can be a rare comorbidity of neuromyelitis optica spectrum disorder. PMID:26439957

  14. Unusual Appearance of an Osteochondral Lesion Accompanying Medial Meniscus Injury

    PubMed Central

    Mine, Takatomo; Ihara, Koichiro; Kawamura, Hiroyuki; Date, Ryo; Chagawa, Kazuki

    2014-01-01

    An osteochondral lesion in the knee joint is caused by a focal traumatic osteochondral defect, osteochondritis dissecans, an isolated degenerative lesion, or diffuse degenerative disease. An osteochondral lesion with a cleft-like appearance accompanying medial meniscus injury is rare without trauma. We report the case of a 13-year-old boy who complained of right knee pain and swelling, with radiographic findings of an osteochondral defect. Arthroscopic inspection showed an osteochondral lesion in the medial condyle of the femur and tibial plateau accompanying a partial medial meniscus discoid tear. Partial meniscectomy was performed, and a microfracture procedure was carried out on the osteochondral defect. The patient was asymptomatic at 2 years' follow-up. This technique is a relatively easy, completely arthroscopic procedure that spares the bone and cartilage and has yielded a good clinical outcome in a skeletally immature patient who had an osteochondral lesion with a cleft-like appearance.

    Rectal duplication (RD) cysts are rare congenital anomalies that can be diagnosed with the presence of another opening in the perineum. They seldom accompany anorectal malformations (ARM). Two cases of RD accompanying ARM at opposite ends of the phenotypic spectrum, are described. A 3-month-old baby and a 2-year-old girl with ARM were scheduled for posterior sagittal anorectoplasty. The infant had an orifice at the anal dimple and the other had an orifice at the vestibulum posterior to the rectovestibular fistula. The infant presented with no other anomalies whereas the older one presented with an unusual coexistence of caudal duplication and caudal regression syndromes. Perioperatively both orifices were found to be related to retrorectal cysts, and were excised. Clinicians should always be alert when dealing with complex malformations. Because these malformations have variable anatomical and clinical presentations, they can represent a diagnostic and therapeutic challenge. PMID:23910814

    The dependence of the electric field in the plane of motion of a nylon string on the string velocity is experimentally studied. The shape and number of the charges that accompany the motion of solid bodies, which have various geometric parameters, in air up to transonic velocities are determined. The formation and shape of electric charges of different signs in an initially neutral dielectric rod are investigated during the motion of a deformation pulse of the same sign along the rod.

    Nurse educators are responsible for accompanying students towards becoming capable, competent professional nurses who are a credit to themselves, their patients, colleagues and profession. Student nurses need, therefore, to be taught to render comprehensive nursing care to patients in all stages of their lives, including when they are dying. Being confronted with human suffering and death is challenging and traumatic. Those exposed to such events on a daily basis need to have a solid foundation of self preservation to see past the pain of suffering and to bring light and hope to those in need. A young student nurse will only experience positive growth and development in these circumstances if she is also cared for and guided with understanding. The researcher utilized a qualitative, explorative, descriptive and contextual design based on the phenomenological approach to enquiry. The following question was asked at the beginning of each unstructured phenomenological interview: "How was if for you to care for a dying or deceased patient?" The central theme identified that student nurses experience turmoil in their different relationships in their accompaniment of the dying patient. Guidelines based on the central theme and sub-themes that emerged from raw data, as well as literature, are offered as strategies to promote/enhance optimal accompaniment of student nurses caring for the dying patient.

    Summary Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric, encapsulated lipomatosis. The exact cause of the disease is unknown; it may be associated with chronic alcoholism and mutations in mitochondrial DNA (A8344G), but there have been cases without these factors reported in the literature. A 29-year-old man with a 6-year history of diabetes mellitus was admitted to our hospital for poorly regulated diabetes and decreased libido. He was not an alcohol consumer. His family history was unremarkable. Physical examination revealed that he had a eunuchoid body shape. There was a symmetric excess fat accumulation in his submandibular, deltoid, nuchal, suprapubic and inguinal areas. He was diagnosed with Madelung's disease, and imaging studies supported the diagnosis. Hormonal evaluation revealed a hypergonadotropic hypogonadism. Karyotype analysis revealed a 47,XXY mutation. Genetic research showed no mitochondrial DNA mutation. Metabolic disorders, such as diabetes mellitus, hyperlipidaemia, hyperuricaemia and liver disease, endocrine gland diseases, such as hypothyroidism, and neurological diseases, such as polyneuropathy and cognitive disorders, may accompany Madelung's disease. The present study represents the first reported case of Madelung's disease accompanied by Klinefelter's syndrome. Learning points Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric and encapsulated lipid accumulation.The exact cause of the disease is unknown.Metabolic disorders, such as diabetes mellitus, hyperlipidaemia, hyperuricaemia and liver disease, endocrine gland diseases, such as hypothyroidism, and neurological diseases, such as polyneuropathy and cognitive disorders, may accompany Madelung's disease.

  19. Real-time implementation of an interactive jazz accompaniment system

    NASA Astrophysics Data System (ADS)

    Deshpande, Nikhil

    Modern computational algorithms and digital signal processing (DSP) are able to combine with human performers without forced or predetermined structure in order to create dynamic and real-time accompaniment systems. With modern computing power and intelligent algorithm layout and design, it is possible to achieve more detailed auditory analysis of live music. Using this information, computer code can follow and predict how a human's musical performance evolves, and use this to react in a musical manner. This project builds a real-time accompaniment system to perform together with live musicians, with a focus on live jazz performance and improvisation. The system utilizes a new polyphonic pitch detector and embeds it in an Ableton Live system - combined with Max for Live - to perform elements of audio analysis, generation, and triggering. The system also relies on tension curves and information rate calculations from the Creative Artificially Intuitive and Reasoning Agent (CAIRA) system to help understand and predict human improvisation. These metrics are vital to the core system and allow for extrapolated audio analysis. The system is able to react dynamically to a human performer, and can successfully accompany the human as an entire rhythm section.

  20. Exoemission accompanying the decomposition of methanol on zinc oxide

    2008-09-01

    The electronic phenomena accompanying the adsorption and dehydrogenation of methanol on zinc oxide were studied using the method of exoemission of negative charges. Postemission excited from ZnO by an electron beam was found to be suppressed by the adsorption of methanol vapor, which exhibited electron acceptor properties. Subsequent heating to temperatures close to the temperature of the beginning of methanol decomposition increased the intensity of exoemission, which was evidence of the participation of emission centers (Oδ-) in dehydrogenation. A possible mechanism of methanol decomposition with the participation of surface V s hole centers (Oδ-) of zinc oxide was suggested.

    We report an extremely rare case of double-layered lateral meniscus accompanied by meniscocapsular separation. The upper accessory meniscus was connected with the posterior horn and middle segment of the lower normal meniscus and was more mobile than the lower normal meniscus. A meniscocapsular separation was evident at the overlapping middle segment. Clinical symptoms were significantly improved by the resection of the upper accessory meniscus and the repair of the meniscocapsular separation. Careful arthroscopic analysis of other associated pathologies together with this rare abnormality was needed to achieve clinical improvement. PMID:26090252

    Scleroderma en coup de sabre, a variant of localized scleroderma is a disorder characterized by fibrosis of connective tissue. We report a 21-year-old female with scleroderma en coup de sabre accompanied by pachydermoperiostosis. She was born to consanguineous parents and her older sister also had pachydermoperiostosis characterized by clubbing of the digits, enlargement of distal parts of the extremities. The two disorders were diagnosed by clinical examination, histological and x-ray findings. In contrast to scleroderma, pachydermoperiostosis is a hypertrophic process characterized by periosteal proliferation of the tubuler bones and hypertrophic skin changes. We discuss this interesting coexistence and review the literature. PMID:17543162

    Mucocele and traumatic neuroma are two lesions related to the traumatic events; however there is only one reported case in which these two entities were perceived simultaneously. The current study reported a 21-year-old man who complained of painless recurrent swelling, accompanied by paresthesia on his left lower labial mucosa. He had a previous history of similar lesion and had been treated with surgery and cauterization last year. The primary clinical impression was a recurrent mucocele. Microscopic surveys displayed a traumatic neuroma in the vicinity of a mucocele which seems to be arising from the previous surgical treatment. PMID:24724117

    There many applications throughout industry and government requiring real-time computing. Any application that monitors and/or controls a process would fit into this category. Some examples are: Nuclear power plants, Steel mills, Space program, etc. General Atomics uses eight real-time computer systems for control and high speed data acquisition required to run the nuclear fusion experiments. Real-Time computing can be defined as the ability to respond to asynchronous external events in a predictable (preferably fast) time frame. Real-Time computer systems are similar to other computers in many ways and may by used for general computing requirements such as Time-Sharing. However special hardware, operating systems and software had to be developed to meet the requirement for real-time computing. Traditionally, real-time computing has been a realm of proprietary operating systems with real-time applications written in FORTRAN and assembly language. In the past, these systems adequately served the needs of the real-time world. Many of these systems that were developed 15 years ago are still being used today. However the real-time world is now changing, demanding new systems to be developed. This paper gives a description of general real-time computer systems and how they differ from other systems. However, the main purpose of this paper is to give a detailed technical description of the hardware and operating systems of an existing proprietary system and a real-time UNIX system. The two real-time computer systems described in detail are Modcomp Classic III/95 with the MAX IV operating system and Modcomp TRI-D 9750 with the REAL/IX.2 operating system.

  5. Behavior of Water Jet Accompanied with Air Suction

    Kawakami, Hironobu; Ishido, Tsutomu; Ihara, Akio

    In order to atomize a liquid, the authors have investigated the behavior of air-water jets. In a series of experiments, we have discovered a strange phenomenon that the water jet accompanied with air suction from the free surface has made a periodic radial splash of water drop. The purpose of the present paper is to clear out the origin of this phenomenon and the behavior of water jet accompanied with air suction. The behavior of water jet has been photographed by a digital camera aided with a flashlight and high-speed video camera. Those experiments enable us to find the origin of a periodic radial splash due to a formation of single air bubble at the flow separation region inside the nozzle and due to explosive expansion of the bubble after injected in the free space. In order to analyze the radial splash of water, we have conducted the equation of spherical liquid membrane. The numerical results obtained have been compared with the experimental results and good agreement has been obtained in radial expansion velocity.

    Spinal hydatid disease is rarely encountered in nonendemic regions. It is a progressive disease that is associated with risks of serious morbidity. The authors report a case of an isolated primary hydatid cyst of the spine in a 34-year-old woman who presented with back pain, which had lasted for 3 months, as well as lower-extremity pain and fatigue, which had persisted for 2 months. A neurological examination yielded findings indicative of upper motor neuron involvement with complete sensory loss below the level of T-11. Magnetic resonance imaging of the spine showed multiple extradural cystic lesions with an abscess formation at T-11 and involvement of the paraspinal muscles. The patient underwent spinal decompression in which stabilization and total excision of the multiple epidural and psoas abscesses and paraspinal multiloculated cysts were performed. The diagnosis of hydatid disease associated with another infection was confirmed by histopathological evaluation. Albendazole was administered during the postoperative period. Previous reports of secondary infections accompanying this disease in extraspinal locations have been published. However, to the best of the authors' knowledge, there have been no publications about a secondary infection associated with hydatidosis in the spinal cord. One should bear in mind that spinal hydatidosis may be accompanied by other infections in endemic regions. Antihelminthic treatment should be administered for a long period following early decompressive surgery and adequate stabilization. PMID:17561751

    Large databases, by their very nature, often serve as repositories of data which may be needed by other systems. The transmission of this data to other systems has in the past involved several layers of human intervention. The Integrated Cargo Data Base (ICDB) developed by Martin Marietta Energy Systems for the Military Traffic Management Command as part of the Worldwide Port System provides data integration and worldwide tracking of cargo that passes through common-user ocean cargo ports. One of the key functions of ICDB is data distribution of a variety of data files to a number of other systems. Development of automated data distribution procedures had to deal with the following constraints: (1) variable generation time for data files, (2) use of only current data for data files, (3) use of a minimum number of select statements, (4) creation of unique data files for multiple recipients, (5) automatic transmission of data files to recipients, and (6) avoidance of extensive and long-term data storage.

DMC is currently executed on both Sun SPARCstation 2 and Sun SPARCstation 10 platforms and routinely used to model bench and crater blasting problems. This paper will document the design and development of the full-featured interface to DMC. The development of the interface will be tracked through the various stages, highlighting the adjustments made to allow the necessary parameters to be entered in terms and units that field blasters understand. The paper also discusses a novel way of entering non-integer numbers and the techniques necessary to display blasting parameters in an understandable visual manner.

    Between January 1 and December 31, 2009, the Alaska Volcano Observatory (AVO) located 8,829 earthquakes, of which 7,438 occurred within 20 kilometers of the 33 volcanoes with seismograph subnetworks. Monitoring highlights in 2009 include the eruption of Redoubt Volcano, as well as unrest at Okmok Caldera, Shishaldin Volcano, and Mount Veniaminof. Additionally severe seismograph subnetwork outages resulted in four volcanoes (Aniakchak, Fourpeaked, Korovin, and Veniaminof) being removed from the formal list of monitored volcanoes in late 2009. This catalog includes descriptions of: (1) locations of seismic instrumentation deployed during 2009; (2) earthquake detection, recording, analysis, and data archival systems; (3) seismic velocity models used for earthquake locations; (4) a summary of earthquakes located in 2009; and (5) an accompanying UNIX tar-file with a summary of earthquake origin times, hypocenters, magnitudes, phase arrival times, location quality statistics, daily station usage statistics, all files used to determine the earthquake locations in 2009, and a dataless SEED volume for the AVO seismograph network.

    We report the linear thermal expansion behaviors of a Zr-based (Vitreloy 1) bulk metallic glass in its as-cast, annealed and crystallized states. Accompanying the glass-liquid transition, the as-cast Vitreloy 1 shows a continuous decrease in the thermal expansivity, whereas the annealed glass shows a sudden increase. The crystallized Vitreloy 1 exhibits an almost unchanged thermal expansivity prior to its melting. Furthermore, it is demonstrated that the nucleation of crystalline phases can induce a significant thermal shrinkage of the supercooled liquid, but with the growth of these nuclei, the thermal expansion again dominates. These results are explained in the framework of the potential energy landscape, advocating that the configurational and vibrational contributions to the thermal expansion of the glass depend on both, structure and temperature.

    We report cases of ectopic ureter accompanied by three types of ureteral duplication that had been diagnosed previously and treated for enuresis. Data from three female patients ranging in age from 1 to 10 years were evaluated. The ectopic ureter was observed on the left in one case, on the right in another and bilateral in the third case. Complete duplication was found in two cases, while the third had incomplete duplication. Ureteroneocystostomy was performed in one case and subtotal nephrectomy was carried out in the other two cases. Ureteroneocystostomy was performed for the ectopic ureter found in the opposite urinary system in one of the cases. Ectopic duplicated ureter should be considered in treatment-resistant enuresis and urinary tract infections and after a careful physical examination, imaging as well as function tests should be performed.

    Evolutionary shifts in plant-herbivore interactions provide a model for understanding the link among the evolution of behaviour, ecological specialization and incipient speciation. Drosophila mojavensis uses different host cacti across its range, and volatile chemicals emitted by the host are the primary cue for host plant identification. In this study, we show that changes in host plant use between distinct D. mojavensis populations are accompanied by changes in the olfactory system. Specifically, we observe differences in olfactory receptor neuron specificity and sensitivity, as well as changes in sensillar subtype abundance, between populations. Additionally, RNA-seq analyses reveal differential gene expression between populations for members of the odorant receptor gene family. Hence, alterations in host preference are associated with changes in development, regulation and function at the olfactory periphery. PMID:27581882

    A classical view of neural coding relies on temporal firing synchrony among functional groups of neurons, however, the underlying mechanism remains an enigma. Here we experimentally demonstrate a mechanism where time-lags among neuronal spiking leap from several tens of milliseconds to nearly zero-lag synchrony. It also allows sudden leaps out of synchrony, hence forming short epochs of synchrony. Our results are based on an experimental procedure where conditioned stimulations were enforced on circuits of neurons embedded within a large-scale network of cortical cells in vitro and are corroborated by simulations of neuronal populations. The underlying biological mechanisms are the unavoidable increase of the neuronal response latency to ongoing stimulations and temporal or spatial summation required to generate evoked spikes. These sudden leaps in and out of synchrony may be accompanied by multiplications of the neuronal firing frequency, hence offering reliable information-bearing indicators which may bridge between the two principal neuronal coding paradigms.

    1984-02-01

    We determined the bacteriology of apparently infected renal calculi and accompanying urinary tract infections, and assessed the potential clinical value of the culture results. Twenty-two branched renal calculi from 16 patients were cultured. Fifteen calculi were infected with 1 or more urease-producing gram-negative enteric bacterium, 2 were infected with a urease-producing bacterium and a nonurease-producing organism, and 5 were sterile. Immersion of infected stones in antimicrobial solutions before culture reduced or eliminated surface bacteria but usually did not eradicate bacteria within the stone. The bacteriology of a stone or stones could be predicted on the basis of available urine culture results in only 2 of the 16 cases. These data suggest that branched renal calculi associated with bacteriuria usually are infected but that documentation of infection and identification of the infecting organism require culture of the stone.

    We present a quasiclassical theory of {alpha} decay accompanied by bremsstrahlung with a special emphasis on the case of {sup 210}Po, with the aim of finding a unified description that incorporates both the radiation during the tunneling through the Coulomb wall and the finite energy E{sub {gamma}} of the radiated photon up to E{sub {gamma}}{approx}Q{sub {alpha}}/{radical}({eta}), where Q{sub {alpha}} is the {alpha}-decay Q-value and {eta} is the Sommerfeld parameter. The corrections with respect to previous quasiclassical investigations are found to be substantial, and excellent agreement with a full quantum mechanical treatment is achieved. Furthermore, we find that a dipole-quadrupole interference significantly changes the {alpha}-{gamma} angular correlation. We obtain good agreement between our theoretical predictions and experimental results.

    We report a 55 year old Japanese man with a history of alcohol abuse, who was in a near fasting state for the previous few days.He was admitted to our hospital with abrupt disturbance of consciousness. He presented disturbance of consciousness with extreme hypoglycemia and ketoacidosis with high β-hydroxybutyric acid concentration. Taking into account his living history, we diagnosed with alcoholic ketoacidosis (AKA). Symptoms ameliorated with glucose injection and fluid loading. AKA patients show abdominal pain, nausea or vomiting, but they are usually alert and lucid despite the severe acidosis. This case, however, presented comatose status caused by hypoglycemia. Poor oral intake of this patient was assumed to be the cause of hypoglycemia. Alcoholism may cause hypoglycemia accompanying with AKA, due to a low carbohydrate intake, the inhibition of gluconeogenesis, and reduced hepaticglycogen storage as seen in this case. Here, we report a case of AKA that demonstrated hypoglycemia with the literature review. PMID:25787101

    The phenomenon in which a certain smell evokes a specific memory is known as the Proust phenomenon. Odor-evoked autobiographic memories are more emotional than those elicited by other sensory stimuli. The results of our previous study indicated that odor-evoked autobiographic memory accompanied by positive emotions has remarkable effects on various psychological and physiological activities, including the secretion of cytokines, which are immune-signaling molecules that modulate systemic inflammation. In this study, we aimed to clarify the neural substrates associated with the interaction between odor-evoked autobiographic memory and peripheral circulating cytokines. We recruited healthy male and female volunteers and investigated the association between brain responses and the concentration of several cytokines in the plasma by using positron emission tomography (PET) recordings when an autographic memory was evoked in participants by asking them to smell an odor that was nostalgic to them. Participants experienced positive emotions and autobiographic memories when nostalgic odors were presented to them. The levels of peripheral proinflammatory cytokines, such as the tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), were significantly reduced after experiencing odor-evoked autobiographic memory. Subtraction analysis of PET images indicated that the medial orbitofrontal cortex (mOFC) and precuneus/posterior cingulate cortex (PCC) were significantly activated during experiences of odor-evoked autobiographic memory. Furthermore, a correlation analysis indicated that activities of the mOFC and precuneus/PCC were negatively correlated with IFN-γ concentration. These results indicate that the neural networks including the precuneus/PCC and mOFC might regulate the secretion of peripheral proinflammatory cytokines during the experience of odor-evoked autobiographic memories accompanied with positive emotions.

  20. Soundtracks to Accompany Visualizations of Nuclear Pasta Simulations

    NASA Astrophysics Data System (ADS)

    2014-09-01

    Nuclear pasta is a substance found in neutron stars and core-collapse supernovae, arising at the extreme densities near nuclear saturation, when the attractive nuclear and repulsive coulomb forces mold the dense sea of protons and neutrons into shapes such as spheres, tubes, and slabs, which somewhat resemble different types of pasta. The structures are analyzed using molecular dynamical simulations for different proton fractions, temperatures, densities, and number of nucleons. The system is stressed by stretching it, squeezing it, or subjecting it to some outside force. In order to obtain a more complete representation of how the nuclear pasta responds, sound tracks were produced to accompany videos of stretching simulations. The audio tracks were made by assuming sound waves are produced from changes in the nucleon density. This density was calculated within a small region at frequent time intervals during the run. The resulting sound track was then synced with a video of the run in order to emphasize the development of the system as the pasta moves and breaks.

  1. Melatonin production accompanies arousal from daily torpor in Siberian hamsters.

    2003-01-01

    Arousal from deep hibernation is accompanied by a transient rise of melatonin (Mel) in circulation; there are no comparable analyses of Mel concentrations in species that undergo much shallower, shorter duration episodes of daily torpor. Serum Mel concentrations were determined during arousal from both natural daily torpor and torpor induced by 2-deoxy-D-glucose (2-DG) treatment (2,500 mg/kg, intraperitoneal [IP]); blood samples were drawn from the retro-orbital sinus of anesthetized Siberian hamsters. For animals kept in darkness during torpor, Mel concentrations were highest during early arousal when thermogenesis is maximal, and they decreased as body temperature increased during arousal and returned to baseline once euthermia was reestablished. In hamsters kept in the light during the torpor bout, Mel concentrations were elevated above basal values during arousal, but the response was significantly blunted in comparison with values recorded in darkness. Increased Mel concentrations were detected in hamsters only during arousal from torpor (either natural or 2-DG induced) and were not simply a result of the drug treatment; hamsters that remained euthermic or manifested mild hypothermia after drug treatment maintained basal Mel concentrations. We propose that increased Mel production may reflect enhanced sympathetic activation associated with intense thermogenesis during arousal from torpor rather than an adjustment of the circadian rhythm of Mel secretion.

  2. Radio rebrightening of the GRB afterglow by the accompanying supernova

    2015-12-01

    The gamma-ray burst (GRB) jet powers the afterglow emission by shocking the surrounding medium, and radio afterglow can now be routinely observed to almost a year after the explosion. Long-duration GRBs are accompanied by supernovae (SNe) that typically contain much more energy than the GRB jet. Here we consider the fact that the SN blast wave will also produce its own afterglow (supernova remnant emission), which will peak at much later time (since it is non-relativistic), when the SN blast wave transitions from a coasting phase to a decelerating Sedov-Taylor phase. We predict that this component will peak generally a few tens of years after the explosion and it will outshine the GRB powered afterglow well-before its peak emission. In the case of GRB 030329, where the external density is constrained by the ˜10-year coverage of the radio GRB afterglow, the radio emission is predicted to start rising over the next decade and to continue to increase for the following decades up to a level of ˜ mJy. Detection of the SN-powered radio emission will greatly advance our knowledge of particle acceleration in ˜0.1c shocks.

    2008-02-26

    A critical component of nervous system development is synapse elimination during early postnatal life, a process known to depend on neuronal activity. Changes in synaptic strength in the form of long-term potentiation (LTP) and long-term depression (LTD) correlate with dendritic spine enlargement or shrinkage, respectively, but whether LTD can lead to an actual separation of the synaptic structures when the spine shrinks or is lost remains unknown. Here, we addressed this issue by using concurrent imaging and electrophysiological recording of live synapses. Slices of rat hippocampus were cultured on multielectrode arrays, and the neurons were labeled with genes encoding red or green fluorescent proteins to visualize presynaptic and postsynaptic neuronal processes, respectively. LTD-inducing stimulation led to a reduction in the synaptic green and red colocalization, and, in many cases, it induced a complete separation of the presynaptic bouton from the dendritic spine. This type of synapse loss was associated with smaller initial spine size and greater synaptic depression but not spine shrinkage during LTD. All cases of synapse separation were observed without an accompanying loss of the spine during this period. We suggest that repeated low-frequency stimulation simultaneous with LTD induction is capable of restructuring synaptic contacts. Future work with this model will be able to provide critical insight into the molecular mechanisms of activity- and experience-dependent refinement of brain circuitry during development.

  4. Increased spatial variance accompanies reorganization of two continental shelf ecosystems.

    Phase transitions between alternate stable states in marine ecosystems lead to disruptive changes in ecosystem services, especially fisheries productivity. We used trawl survey data spanning phase transitions in the North Pacific (Gulf of Alaska) and the North Atlantic (Scotian Shelf) to test for increases in ecosystem variability that might provide early warning of such transitions. In both time series, elevated spatial variability in a measure of community composition (ratio of cod [Gadus sp.] abundance to prey abundance) accompanied transitions between ecosystem states, and variability was negatively correlated with distance from the ecosystem transition point. In the Gulf of Alaska, where the phase transition was apparently the result of a sudden perturbation (climate regime shift), variance increased one year before the transition in mean state occurred. On the Scotian Shelf, where ecosystem reorganization was the result of persistent overfishing, a significant increase in variance occurred three years before the transition in mean state was detected. However, we could not reject the alternate explanation that increased variance may also have simply been inherent to the final stable state in that ecosystem. Increased variance has been previously observed around transition points in models, but rarely in real ecosystems, and our results demonstrate the possible management value in tracking the variance of key parameters in exploited ecosystems.

    Patient: Male, 81 Final Diagnosis: Sclerosed hemangioma Symptoms: — Medication: — Clinical Procedure: Autopsy Specialty: Diagnostics, Laboratory Objective: Rare disease Background: A sclerosed hemangioma of the liver, an extremely rare type of benign hepatic tumor, was found at autopsy. Case Report: An 81-year-old Japanese man was admitted to our hospital for surgical resection of squamous cell carcinoma of the skin in his left forearm. At admission, serological tests for hepatitis B surface antigen and hepatitis C antibody were negative with no evidence of cirrhosis. At 2, 3, and 5 months after the removal of the forearm tumor, skin grafting was performed because of unhealed skin ulceration. Although anti-bacterial drugs were prescribed, the patient died after the 3rd skin graft (5 months after the surgery) because of pneumonia. During the treatment course, the patient was diagnosed as having multiple liver masses suspected to be cysts of the liver based on non-contrasted computed tomography results. Autopsy revealed a sclerosed hemangioma occupying the entire left lobe accompanied by multiple small cavernous hemangiomas in the right lobe of the liver. Conclusions: Sclerosed hemangioma, a rare benign disease, occurred in association with degeneration and sclerosis of cavernous hemangiomas of the liver. The VEGF pathway may be involved in the genesis of cavernous and sclerosed hemangioma of the liver. PMID:26116763

  6. Accompanying coordinate expansion formulas derived with the solid harmonic gradient.

    2002-02-01

    A series of accompanying coordinate expansion (ACE) formulas for calculating the electron repulsion integral (ERI) over both generally and segmentally contracted solid harmonic (SH) Gaussian-type orbitals (GTOs) can be rederived by the use of the modified operator (called solid harmonic gradient here) of the spherical tensor gradient of Bayman and the reducing solid harmonic gradient defined in this article. The final general formulas contain the reducing mixed solid harmonics defined in a previous article [Ishida, K. J Chem Phys 1999, 111, 4913] and the reducing triply mixed solid harmonics defined previously [Ishida, K. J Chem Phys 2000, 113, 7818]. Each general formula in the series is named ACEb1k1, ACEb2k3, or ACEb3k3. New general algorithm can be obtained inductively from the general formula named ACEb2k3, in addition to the previously developed ACEb1k1 and ACEb3k3. For calculating ERI practically, we select one of these ACE algorithms, as it gives the minimum floating-point operation (FLOP) count. Theoretical assessment by the use of the FLOP count is performed for the (LL/LL) class of ERIs over both generally and segmentally contracted SH-GTOs (L = 1-3). It is found that the present ACE is theoretically the fastest among all rigorous methods in the literature. PMID:11908501

  7. Explosive Nucleosynthesis in GRB Jets Accompanied by Hypernovae

    Two-dimensional hydrodynamic simulations are performed to investigate explosive nucleosynthesis in a collapsar using the model of MacFadyen and Woosley (1999). It is shown that {sup 56}Ni is not produced in the jet of the collapsar sufficiently to explain the observed amount of a hypernova when the duration of the explosion is {approx} 10 sec, which is considered to be the typical timescale of explosion in the collapsar model. Even though a considerable amount of {sup 56}Ni is synthesized if all explosion energy is deposited initially, the opening angles of the jets become too wide to realize highly relativistic outflows and gamma-ray bursts in such a case. From these results, it is concluded that the origin of {sup 56}Ni in hypernovae associated with GRBs is not the explosive nucleosynthesis in the jet. We consider that the idea that the origin is the explosive nucleosynthesis in the accretion disk is more promising. We also show that the explosion becomes bi-polar naturally due to the effect of the deformed progenitor. This fact suggests that the {sup 56}Ni synthesized in the accretion disk and conveyed as outflows are blown along to the rotation axis, which will explain the line features of SN 1998bw and double peaked line features of SN 2003jd. Some fraction of the gamma-ray lines from {sup 56}Ni decays in the jet will appear without losing their energies because the jet becomes optically thin before a considerable amount of {sup 56}Ni decays as long as the jet is a relativistic flow, which may be observed as relativistically Lorentz boosted line profiles in future. We show that abundance of nuclei whose mass number {approx} 40 in the ejecta depends sensitively on the energy deposition rate, which is a result of incomplete silicon burning and alpha-rich freezeout. So it may be determined by observations of chemical composition in metal poor stars which model is the proper one as a model of a gamma-ray burst accompanied by a hypernova.

    OBJECTIVES: To determine the proportion of patients who are accompanied by another person (ie, partner, child, relative, friend) during visits to their doctors; to describe the demographic characteristics and role(s) assumed by the main accompanying person and the nature of the presenting dyads; and to describe the influence of the main accompanying person on the patient-doctor interaction. DESIGN: Prospective observational survey. SETTING: Family practices in London, Ont, and surrounding area. PARTICIPANTS: Eight family physicians completed surveys on 100 consecutive patients attending for both regularly scheduled and emergency visits. MAIN OUTCOME MEASURES: Roles and influence of the main accompanying person. RESULTS: Approximately one third (30.4%) of patients were accompanied during visits to their doctors. Children and patients older than 75 years most frequently had another person with them. Most patients (74.1%) were accompanied by one person who most often was female (72.6%) and between the ages of 21 and 40 years (53.6%). The accompanying person's role was most frequently described by doctors as an advocate for the patient (n = 235, 68.5%). If the accompanying person was a child, however, the role was most often described as a silent observer (n = 36, 68.6%). The influence of the main accompanying person on the patient-doctor encounter was usually described as positive (95.1%). CONCLUSIONS: Physicians report that people accompanying patients usually have a positive influence on medical encounters. Future studies need to include patients' and accompanying persons' perspectives. PMID:9721420

    Laser reflective tomography is a long-range, high-resolution active detection technology, whose advantage is that the spatial resolution is unrelated with the imaging distance. Accompany satellite is a specific satellite around the target spacecraft with encircling movement. When using the accompany satellite to detect the target aircraft, multi-angle echo data can be obtained with the application of reflective tomography imaging. The feasibility of such detection working mode was studied in this article. Accompany orbit model was established with horizontal circular fleet and the parameters of accompany flight was defined. The simulation of satellite-to-satellite reflective tomography imaging with satellite-accompany was carried out. The operating mode of reflective tomographic data acquisition from monostatic laser radar was discussed and designed. The flight period, which equals to the all direction received data consuming time, is one of the important accompany flight parameters. The azimuth angle determines the plane of image formation while the elevation angle determines the projection direction. Both of the azimuth and elevation angles guide the satellite attitude stability controller in order to point the laser radar spot on the target. The influences of distance between accompany satellite and target satellite on tomographic imaging consuming time was analyzed. The influences of flight period, azimuth angle and elevation angle on tomographic imaging were analyzed as well. Simulation results showed that the satellite-accompany laser reflective tomography is a feasible and effective method to the satellite-to-satellite detection.

    Cutaneous manifestations of migraine are infrequent and their spectrum is reduced to the red ear syndrome (RES) and eyelid disorders. We report a case of a 26-year-old woman with migraine accompanied by extensive erythema, which involved right ear and cheek and left hemithorax. She fulfilled proposed criteria of RES. We started preventive therapy with a significant response. This is the first description in the literature of an erythema accompanying migraine attacks broadly exceeding the ear. PMID:26474080

  3. The auditory scene: an fMRI study on melody and accompaniment in professional pianists.

    The auditory scene is a mental representation of individual sounds extracted from the summed sound waveform reaching the ears of the listeners. Musical contexts represent particularly complex cases of auditory scenes. In such a scenario, melody may be seen as the main object moving on a background represented by the accompaniment. Both melody and accompaniment vary in time according to harmonic rules, forming a typical texture with melody in the most prominent, salient voice. In the present sparse acquisition functional magnetic resonance imaging study, we investigated the interplay between melody and accompaniment in trained pianists, by observing the activation responses elicited by processing: (1) melody placed in the upper and lower texture voices, leading to, respectively, a higher and lower auditory salience; (2) harmonic violations occurring in either the melody, the accompaniment, or both. The results indicated that the neural activation elicited by the processing of polyphonic compositions in expert musicians depends upon the upper versus lower position of the melodic line in the texture, and showed an overall greater activation for the harmonic processing of melody over accompaniment. Both these two predominant effects were characterized by the involvement of the posterior cingulate cortex and precuneus, among other associative brain regions. We discuss the prominent role of the posterior medial cortex in the processing of melodic and harmonic information in the auditory stream, and propose to frame this processing in relation to the cognitive construction of complex multimodal sensory imagery scenes.

  5. Steam thermolysis of tire shreds: modernization in afterburning of accompanying gas with waste steam

    NASA Astrophysics Data System (ADS)

    Kalitko, V. A.

    2010-03-01

    On the basis of experience in the commercial operation of tire-shred steam thermolysis in EnresTec Inc. (Taiwan) producing high-grade commercial carbon, liquid pyrolysis fuel, and accompanying fuel gas by this method, we have proposed a number of engineering solutions and calculated-analytical substantiations for modernization and intensification of the process by afterburning the accompanying gas with waste steam condensable in the scrubber of water gas cleaning of afterburning products. The condensate is completely freed of the organic pyrolysis impurities and the necessity of separating it from the liquid fuel, as is the case with the active process, is excluded.

    Cases of Henoch-Schönlein purpura and purpura nephritis accompanied by pulmonary hemorrhage are rare. Mild cases are easily ignored due to a lack of evident bleeding, and severe cases may be fatal. We have only treated one patient with Henoch-Schönlein nephritis (HSPN), a female child. The clinical manifestations were not evident, however, the imaging manifestations were clear. Finally, the patient was definitively diagnosed with HSPN accompanied by pulmonary hemorrhage. Following treatment with antiinflammatory and steroidal agents, tripterygium glycosides and traditional Chinese medicine, the patient recovered. In the present study, we report the diagnosis and treatment of this disease, with a review of the literature. PMID:23737885

  14. The impact of parental accompaniment in paediatric trauma: a helicopter emergency medical service (HEMS) perspective

    PubMed Central

    2014-01-01

    Major trauma remains a significant cause of mortality and morbidity in young people and adolescents throughout the western world. Both the physical and psychological consequences of trauma are well documented and it is shown that peri-traumatic factors play a large part in the emotional recovery of children involved in trauma. Indeed, parental anxiety levels may play one of the biggest roles. There are no publically available guidelines on pre-hospital accompaniment, and where research has been done on parental presence it often focuses primarily on the parents or staff, rather than the child themselves. Whilst acknowledging the impact on parents and staff, the importance of the emotional wellbeing of the child should be reinforced, to reduce the likelihood of developing symptoms in keeping with post-traumatic stress disorder. This non-systematic literature review, aims to examine the impact of parental accompaniment to hospital, following paediatric trauma, and to help pre-hospital clinicians decide whether accompaniment would be of benefit to their patient population. The lack of published data does not enable a formal recommendation of parental accompaniment in the helicopter to be mandated, though it should be the preference in land based conveyance. Future research is needed into the emotional recovery of children after trauma, as well as the experiences of patient, parent and staff during conveyance. PMID:24887082

  15. No smile like another: adult age differences in identifying emotions that accompany smiles

    PubMed Central

    Riediger, Michaela; Studtmann, Markus; Westphal, Andrea; Rauers, Antje; Weber, Hannelore

    2014-01-01

    People smile in various emotional contexts, for example, when they are amused or angry or simply being polite. We investigated whether younger and older adults differ in how well they are able to identify the emotional experiences accompanying smile expressions, and whether the age of the smiling person plays a role in this respect. With this aim, we produced 80 video episodes of three types of smile expressions: positive-affect smiles had been spontaneously displayed by target persons as they were watching amusing film clips and cartoons. Negative-affect smiles had been displayed spontaneously by target persons during an interaction in which they were being unfairly accused. Affectively neutral smiles were posed upon request. Differences in the accompanying emotional experiences were validated by target persons' self-reports. These smile videos served as experimental stimuli in two studies with younger and older adult participants. In Study 1, older participants were less likely to attribute positive emotions to smiles, and more likely to assume that a smile was posed. Furthermore, younger participants were more accurate than older adults at identifying emotional experiences accompanying smiles. In Study 2, both younger and older participants attributed positive emotions more frequently to smiles shown by older as compared to younger target persons, but older participants did so less frequently than younger participants. Again, younger participants were more accurate than older participants in identifying emotional experiences accompanying smiles, but this effect was attenuated for older target persons. Older participants could better identify the emotional state accompanying smiles shown by older than by younger target persons. Taken together, these findings indicate that there is an age-related decline in the ability to decipher the emotional meaning of smiles presented without context, which, however, is attenuated when the smiling person is also an older adult

  16. FIRE4, LiteRed and accompanying tools to solve integration by parts relations

    NASA Astrophysics Data System (ADS)

    Smirnov, A. V.; Smirnov, V. A.

    2013-12-01

    We present the new version of the Mathematica code FIRE and ideas behind it. It can be applied together with the recently developed code LiteRed by Lee in order to provide an integration by parts reduction to master integrals for quite complicated families of Feynman integrals. As an example, we consider four-loop massless propagator integrals for which LiteRed provides reduction rules and FIRE assists to apply these rules. So, as a by-product one obtains a four-loop variant of the well-known algorithm MINCER. The existence of these explicit reduction rules shows that any four-loop massless propagator integral can be reduced to a linear combination of master integrals in the sense of a mathematical theorem. We also describe various algebraic ways to find additional relations between master integrals associated with several families of Feynman integrals.

    2005-12-15

    Knowledge of the effectiveness and efficiency of computers is important when working with high performance systems. The monitoring of such systems is advantageous in order to foresee possible misfortunes or system failures. Ganglia is a software system designed for high performance computing systems to retrieve specific monitoring information. An alternative storage facility for Ganglia's collected data is needed since its default storage system, the round-robin database (RRD), struggles with data integrity. The creation of a script-driven MySQL database solves this dilemma. This paper describes the process took in the creation and implementation of the MySQL database for use by Ganglia. Comparisons between data storage by both databases are made using gnuplot and Ganglia's real-time graphical user interface.

    2015-10-01

    We aimed to identify whether rotavirus, human parechovirus, or enterovirus are causative or associated viral pathogens of seizures accompanied by diffuse cerebral white matter injury in neonates. Thirty neonates who presented with seizures and diffusion-restriction in the widespread bilateral cerebral white matter on diffusion-weighted magnetic resonance imaging (MRI) were included in this study. All patients were tested for rotavirus, human parechovirus, and enterovirus by using reverse transcription PCR. Stool, cerebrospinal fluid, and serum samples were examined in 30, 25, and 20 patients, respectively. Rotavirus was detected in stool samples from all 30 patients (100%). Stool samples from 5 patients (16.7%) were also positive for enterovirus. Rotavirus or human parechovirus were not detected in any cerebrospinal fluid samples from 25 patients, but 1 patient tested positive for enterovirus. No virus was detected in any of 20 patient sera. This study indicated an association between rotavirus and seizures accompanied by diffuse cerebral white matter lesions in neonates. PMID:25637646

  1. Pitch-informed solo and accompaniment separation towards its use in music education applications

    NASA Astrophysics Data System (ADS)

    Cano, Estefanía; Schuller, Gerald; Dittmar, Christian

    2014-12-01

    We present a system for the automatic separation of solo instruments and music accompaniment in polyphonic music recordings. Our approach is based on a pitch detection front-end and a tone-based spectral estimation. We assess the plausibility of using sound separation technologies to create practice material in a music education context. To better understand the sound separation quality requirements in music education, a listening test was conducted to determine the most perceptually relevant signal distortions that need to be improved. Results from the listening test show that solo and accompaniment tracks pose different quality requirements and should be optimized differently. We propose and evaluate algorithm modifications to better understand their effects on objective perceptual quality measures. Finally, we outline possible ways of optimizing our separation approach to better suit the requirements of music education applications.

    We reported a case of recurrence of localized thymoma accompanied with hypogammaglobulinemia (Good's syndrome) 20 years after surgery. A 74-year-old man was admitted to this hospital because of mediastinal tumor and chronic pulmonary infection. He had been thymectomised at the age of 55 because of spindle cell thymoma. After that, he had been asymptomatic until January 1997, when he began to have a recurrent productive cough, and low-grade fever. Laboratory findings revealed hypogammaglobulinemia. Percutaneous needle biopsy of the mediastinal tumor revealed spindle cell thymoma. Therefore, hypogammaglobulinemia with thymoma (Good's syndrome) accompanied with a chronic lower respiratory tract infection was diagnosed. Immunologic studies revealed a marked decrease of CD 20 positive cells and decreased lymphocyte activation under the stimuli of phytohemagglutinin and concanavalin A. The thymoma was resected in Dec 1997, but the serum immunoglobulin showed no increase at al. PMID:11974900

    2014-01-01

    In reptiles, sex-determining mechanisms have evolved repeatedly and reversibly between genotypic and temperature-dependent sex determination. The gene Dmrt1 directs male determination in chicken (and presumably other birds), and regulates sex differentiation in animals as distantly related as fruit flies, nematodes and humans. Here, we show a consistent molecular difference in Dmrt1 between reptiles with genotypic and temperature-dependent sex determination. Among 34 non-avian reptiles, a convergently evolved pair of amino acids encoded by sequence within exon 2 near the DM-binding domain of Dmrt1 distinguishes species with either type of sex determination. We suggest that this amino acid shift accompanied the evolution of genotypic sex determination from an ancestral condition of temperature-dependent sex determination at least three times among reptiles, as evident in turtles, birds and squamates. This novel hypothesis describes the evolution of sex-determining mechanisms as turnover events accompanied by one or two small mutations. PMID:25540158

    Size distributions of air showers accompanied with bundle of high energy gamma rays and/or large size bursts under emulsion chambers, to study the composition of primary cosmic rays and also characteristics of high energy nuclear interaction. Air showers initiated by particles with a large cross section of interaction may develop from narrow region of the atmosphere near the top. Starting levels of air showers by particles with smaller cross section fluctuate in wider region of the atmosphere. Air showers of extremely small size accompanied with bundle of gamma rays may be ones initiated by protons at lower level after penetrating deep atmosphere without interaction. It is determined that the relative size distribution according to the total energy of bundle of gamma rays and the total burst size observed under 15 cm lead absorber.

    In this study, we analyzed the time-depended scenario of stress response cascade preceding and accompanying brain hemorrhages in newborn rats using an interdisciplinary approach based on: a morphological analysis of brain tissues, coherent-domain optical technologies for visualization of the cerebral blood flow, monitoring of the cerebral oxygenation and the deformability of red blood cells (RBCs). Using a model of stress-induced brain hemorrhages (sound stress, 120 dB, 370 Hz), we studied changes in neonatal brain 2, 4, 6, 8 h after stress (the pre-hemorrhage, latent period) and 24 h after stress (the post-hemorrhage period). We found that latent period of brain hemorrhages is accompanied by gradual pathological changes in systemic, metabolic, and cellular levels of stress. The incidence of brain hemorrhages is characterized by a progression of these changes and the irreversible cell death in the brain areas involved in higher mental functions. These processes are realized via a time-depended reduction of cerebral venous blood flow and oxygenation that was accompanied by an increase in RBCs deformability. The significant depletion of the molecular layer of the prefrontal cortex and the pyramidal neurons, which are crucial for associative learning and attention, is developed as a consequence of homeostasis imbalance. Thus, stress-induced processes preceding and accompanying brain hemorrhages in neonatal period contribute to serious injuries of the brain blood circulation, cerebral metabolic activity and structural elements of cognitive function. These results are an informative platform for further studies of mechanisms underlying stress-induced brain hemorrhages during the first days of life that will improve the future generation's health.

    Objective: The objective of the present study was to investigate the early diagnosis and treatment of trauma in the knee joints accompanied with popliteal vascular injury. Methods: Fifteen cases of patients with trauma in knee joints accompanied with popliteal vascular injury. These patients included 8 males and 6 females between the ages of 27 and 62, the average age being 39.2. Data of clinical symptoms and signs; blood oxygen saturation, color Doppler examination; vascular intervention by DSA angiography; and surgical operations were analyzed to clearly identify their role in early diagnosis and treatment. Results: In the patient group for this study there were: 1 death case; 4 stage I amputation cases; 4 stage II amputation cases due to failure to salvage limbs; and 6 cases with patients who had successful limb salvage. The six cases of limb survival patients were followed up for 12 to 60 months, with an average follow up time of 28.3 months. The excellent rate of joint function of these patients with successful limb salvage was 83.3%. Conclusions: For patients with injured limbs, unclear dorsalis pedis artery palpation, decreased skin temperature, and decreased oxygen saturation of the toes, clinical manifestations combined with proper auxiliary inspection (such as color Doppler and blood vessel angiography of interventional DSA) enabled early diagnose of peripheral trauma in the knee joint accompanied with popliteal vascular injury.

    Mulberry hypertrophy occasionally coexists with sinonasal pathologies. There are very few reports in the literature on this clinical entity. We conducted a retrospective study to draw attention to this condition in the context of accompanying sinonasal pathologies. Our study group was made up of 68 patients-51 males and 17 females, aged 13 to 57 years (mean: 34.9)-who had been diagnosed with mulberry hypertrophy and at least one accompanying sinonasal pathology. All patients had a long-standing chronic discharge. Forty-nine of these patients (72.1%) had unilateral mulberry hypertrophy. The most common concomitant pathologies were chronic rhinosinusitis and ostiomeatal complex disease; others included septal deviation, nasal polyposis, allergic rhinitis, and concha bullosa. Thirty-six patients (52.9%) with varying degrees of choanal/nasal obstruction were operated on with endoscopic excision to treat the mulberry hypertrophy. In all, most patients underwent some sort of surgery to treat either the mulberry hypertrophy or the accompanying sinonasal pathology. Based on our findings, we suggest a clinical staging system to serve as a way to standardize management and guide future basic and clinical research. PMID:27551846

    This article evaluates the "Bobby Pin" procedure in the correction of myogenic ptosis accompanying extraocular muscle weakness. We retrospectively reviewed 26 eyelids of 13 patients who underwent "Bobby Pin" procedure for myogenic ptosis accompanying extraocular muscle weakness. We evaluated the patients' clinical features such as age, etiology of ptosis, symptoms, standard ptosis measurements, associated systemic diseases, additional ophthalmic conditions, complications, and recurrence. Etiology of myogenic ptosis and extraocular muscle weakness was oculopharyngeal dystrophy in 4 (31%) patients, chronic progressive external ophthalmoplegia in 4 (31%) patients, myotonic dystrophy in 2 (23%) patients, and idiopathic in 3 (15%) patients. The mean levator function was approximately 5 mm pre- and post-operatively (range 1 to 12 mm). The mean margin-to-reflex distance 1 increased from -1.1 mm (below the light reflex) pre-operatively to +0.4 mm (above the light reflex) post-operatively. After a mean follow-up of 40 months, only 1 (8%) patient experienced ptosis recurrence. Upper eyelids were symmetric in both contour and height in all patients. Mild superficial keratopathy involving less than 10% of cornea was observed in 4 (31%) patients. The "Bobby Pin" procedure is an effective and long-lasting treatment option for correcting acquired ptosis accompanying extraocular muscle weakness. The procedure is safe, simple, easily learned, time- and cost-effective, and does not require any expensive equipment. PMID:27541941

    Objectives Soft tissue haemangiomas are common benign vascular lesions that can be accompanied by reactive changes in the adjacent bone structure. This study aimed to discuss the MRI features of soft-tissue haemangiomas with an emphasis on changes in bone. Methods The radiographic and MRI findings of 23 patients (9 males, 14 females; mean age 25 years; age range 2–46 years) with soft-tissue haemangiomas were analysed retrospectively. MR images were evaluated for location of the lesion, size, configuration, signal features, contrast patterns, proximity to adjacent bone and changes in the accompanying bone. Excisional biopsy was performed in 15 patients. Results Radiographs demonstrated phleboliths in 8 patients (34%) and reactive bone changes in 4 (19%). On MRI, T1 weighted images showed that most of the lesions were isointense or isohyperintense, as compared with muscle tissue; however, on T2 weighted images all lesions appeared as hyperintense. Following intravenous gadolinium-diethylene triamine pentaacetic acid (DTPA) administration, homogeneous enhancement was observed in 3 lesions and heterogeneous enhancement was seen in 19. No enhancement was observed in one patient. Bone atrophy adjacent to the lesion was observed in four patients. Conclusion MRI is the most valuable means of diagnosing deep soft-tissue haemangiomas. Bone changes can accompany deeply situated haemangiomas; in four of our patients, we found atrophy of the bone adjacent to the lesion. To our knowledge, this is the first report in the literature regarding atrophy of the bone adjacent to a lesion. PMID:21123304

    Social buffering is a phenomenon in which stress in an animal is ameliorated when the subject is accompanied by a conspecific animal(s) during exposure to distressing stimuli. We previously reported that in male Wistar rats, the presence of another Wistar rat mitigates conditioned fear responses to an auditory conditioned stimulus (CS). Subsequent analyses revealed several characteristics of this social buffering of conditioned fear responses. However, information regarding the specificity of accompanying conspecifics is still limited. In the present study, we assessed whether rats of other strains could induce social buffering in Wistar rats. When a fear-conditioned Wistar subject was re-exposed to the CS alone, we observed increased freezing and decreased investigation and walking, as well as elevated corticosterone levels. The presence of a Wistar, Sprague-Dawley, or Long-Evans rat blocked these responses, suggesting that social buffering was induced by these strains of rats. In contrast, a Fischer 344 rat did not induce social buffering in the Wistar subject. We further found that an inbred Lewis rat induced social buffering whereas a Brown Norway rat, a strain that has been established independently from Wistar rats, did not. These results suggest that the difference in origin, rather than the inbred or outbred status of the associate rat, seemed to account for the lack of social buffering induced by the F344 rats. Based on these findings, we conclude that strains of an accompanying conspecific can affect the efficacy of social buffering in rats. PMID:27191856

    We previously reported two schizophrenic patients with characteristic hallucinations consisting of auditory hallucinations accompanied by visual hallucinations of the speaker's face. The patient sees the face of the hallucinatory speaker in his/her mind and hears the voice talking inwardly. We termed these experiences physiognomy-accompanying auditory hallucinations. In this report, we present 10 patients with schizophrenia showing physiognomy-accompanying auditory hallucinations and evaluate the characteristics of these clinical symptoms. Moreover we consider what the symptoms mean for patients and the metabasis from structural aspects. Lastly, we consider how we can treat these patients living autistic lives with the symptoms. During physiognomy-accompanying auditory hallucinations, the realistic face moves its mouth and talks to the patient expressively. In early onset cases, the faces of various real people appear talking about ordinary things while in late onset cases, the faces can be imaginary but are mainly real people talking about ordinary or delusional things. We suppose that these characteristics of the symptoms unify the schizophrenic world overwhelmed by "a force of non-sense" to "the sense field". "The force of non-sense" is a substantial power but cannot be reduced to the real meaning. And we suppose that not visual reality but the intensity of auditory hallucinations of the face brings about the overwhelming intensity of symptoms and the substantiality of this intensity depends on the states of excessive fullness of "the force of non-sense". With these symptoms patients see the narration of auditory hallucinations through the facial image and the content of auditory hallucinations is compressed into the movement of visual hallucinations of the speaker's face. The form of symptoms is realistic but the speaker's face and voice are beyond ordinary time and space. The symptoms are essentially different from ordinary perception. The visual

    Encouraging male partners to accompany women to antenatal care (ANC) is an important first step in engaging men on maternal and newborn health. However, little is known regarding the impact of male partner antenatal accompaniment beyond HIV-related perinatal outcomes. A systematic review was conducted to synthesize the evidence on the influence of male accompaniment on non-HIV outcomes during pregnancy and into the postpartum period. Eligible studies were published in English from 2003 to 2013 and evaluated the effect of male antenatal accompaniment on perinatal health in a developing country. Four electronic databases and selected reference lists were searched. Out of 84 potential citations retrieved, seven publications were retained for the assessment of male antenatal accompaniment's influence using iterative thematic analysis. During pregnancy, male antenatal accompaniment positively impacted women's knowledge of danger signs, but did not affect birth preparedness, ANC utilization, or miscarriages. During labor and delivery, men's ANC presence was associated with increases in institutional delivery and skilled birth attendance, but with no effect for birth-related outcomes. During the early postnatal period, male antenatal accompaniment was associated with higher uptake of postnatal services, but with mixed effects on breastfeeding and newborn survival. Couples' increased communication on pregnancy care and men's subsequent motivation to ensure safe delivery may explain these observed benefits. Inadequate communication, late accompaniment, or partner type may explain the lack of influence on some outcomes. More efforts are needed to expand the implementation and evaluation of male involvement strategies to improve perinatal health. PMID:25656727

    "Death and its approach represent a field of study for nurses": thus ended his article Montserrat Salvador Borrell in Revista ROL de Enfermería in November 2010. Address it also from the point of view of the soul brings perspective and gives horizon in the sense of one greater understanding. Death, contemplated and lived exclusively from the material side, flees from as a not only traumatic event for which the experience but also unsurpassed for loved ones. Paradoxically, it's a more natural and frequent phenomenon. Why humans so hard that naturalness? Because we have not cultivated, sometimes not even recognized, other spiritual nature which forms us and who has the key to give sense to the decisive events. For many spiritual traditions, death is birth to another world that, from here, we call beyond. In accompaniment of soul seminars, based on the teachings transmitted by Elisabeth Kübler Ros and Marie Lise Labonte, patterns are learned to accompany the personality and soul--which does not always go according to the time of split--and to help the soul to rediscover his way toward the light, toward the origin. The soul knows it well, but the emotional ties forged during his earthly journey can retain it and hinder the process, which becomes slow and painful. The accompaniment of the soul is a "service" human, social and spiritual. Guides in a forgotten and often feared territory is a relief. You have guides to prepare the great journey allows, especially, make peace with himself with others I with the world.

    Magnetostriction was investigated for layered A-type antiferromagnetic SmMnO3 showing large magnetocapacitive effects around a temperature (TTP) where ferrimagnetically coupled Mn 3d and Sm 4f moments were reversed simultaneously. Upon sweeping temperature or a magnetic field, a significant lattice distortion was observed at TTP or the coercive field, respectively. This indicates that the lattice is strongly coupled with the magnetic configuration. We discuss the lattice distortion accompanied by the magnetization reversal in terms of a partial change in the orbital state of Mn eg electrons.

    The experimental data of extensive air showers (EAS) accompanied by gamma-families, with total energy greater than 10 TeV, were compared with a Monte Carlo simulation with a rising cross section proportional to E sup 0.04 for the p-air inelastic cross section. It is found that the absolute intensity of size spectrum of such EAS is strongly affected by the primary protons intensity at 10 to the 15th power approx. 10 to the 16th power eV region and the experimental size spectrum agrees with the simulated spectra for the p-poor primary composition better than the p-rich one.

    Very-long-period (VLP) pulses with period of 6-7s, displaying similar waveforms, were identified in 1998 from broadband seismographs around the summit crater. These pulses accompanied most of multiphase (MP) earthquakes, a type of long-period event locally defined at Merapi Volcano. Source mechanisms for several VLP pulses were examined by applying moment tensor inversion to the waveform data. Solutions were consistent with a crack striking ???70?? and dipping ???50?? SW, 100m under the active dome, suggest pressurized gas transport involving accumulation and sudden release of 10-60 m3 of gas in the crack over a 6s interval.

    The emission of particles due to deformation and fracture of materials has been investigated. The emission of electrons (exoelectron emission), ions, neutral species, photons (triboluminescence), as well as long wavelength electromagnetic radiation was observed; collectively these emissions are referred to as fractoemission. This paper describes measurements of the neutral emission accompanying the fracture of single-crystal MgO. Masses detected are tentatively assigned to the emission of H2, CH4, H2O, CO, O2, CO2, and atomic Mg. Other hydrocarbons are also observed. The time dependencies of some of these emissions relative to fracture are presented for two different loading conditions.

    We describe a rare case of transient thyrotoxicosis secondary to painless thyroiditis accompanied by panhypopituitarism caused by ruptured Rathke's cleft cyst. A 32-year-old man presented with vomiting and diarrhea. Laboratory data showed that he had transient hypercalcemia, primary thyrotoxicosis due to painless thyroiditis and panhypopituitarism. The sellar magnetic resonance imaging showed cystic macroadenoma. He underwent surgical exploration. Histological examination showed a ruptured Rathke's cleft cyst. Our case suggests that, although rare, it is important to recognize the possibility of coexistence of hypopituitarism in patients with primary thyrotoxicosis. PMID:22185992

    Hereditary spastic paraplegia(HSP or SPG) is a clinically and genetically heterogeneous group of neurodegenerative diseases characterized by progressive spasticity, weakness of lower limbs, and pathologically by retrograde axonal degeneration of corticospinal tracts and posterior spinal tracts. Presence of additional features allows differentiation between simple and complex forms of the disease. Genetically, 16 loci for HSP accompanied by distal amyotrophy have been mapped, for which 13 genes have been identified. With the identification of causative genes, the molecular mechanism of this disease is gradually elucidated. PMID:23926010

    In situ , observation of twinning and detwinning in magnesium single crystals during tension-compression cyclic loading was made using optical microscopy. A quantitative analysis of plastic strain indicates that twinning and detwinning experience two stages, low and high work hardening de-twinning, and pure re-twinning and fresh twinning combined with retwinning. Slip is always activated. For the first time, inverse slip accompanying with pure retwinning and high work hardening detwinning was experimentally identified, which provides insights in better understanding of the activity of twining, detwinning, and slips.

    The availability of ultra-short and strong light sources opens the door for a variety of new experiments such as transient absorption, where optical properties of systems can be studied in extreme nonequilibrium situations. The nonequilibrium Green's function formalism is an efficient approach to investigate these processes theoretically. Here we apply the method to the light-matter interaction of the magnesium 2p core level accompanied by electron-plasmon interaction due to collective excitations in the conduction band. The plasmons are described as massive bosonic quasi-particle excitations, leading to a second-order equations of motion, requiring a new approach for their propagation.

    Horseshoe kidney (HSK) is the most common fusion anomaly of kidneys. Diagnosis of horseshoe kidneys is made by the demonstration of an isthmus or band of renal tissue between the lower poles of the kidneys. Connection between the upper poles of the kidneys is extremely rare. Several types of skeletal anomalies can be seen concomitantly with HSK. In our present case, where the patient was a 3-year-old male, the connection of renal tissue was located between the upper poles of the kidneys. Furthermore, there was an accompanying spina bifida and Gibbus deformity secondary to anterior hypoplasia of the T10 vertebral body. PMID:27114084

    Esophageal perforation is the fastest progressing and the most life-threatening disruption of gastrointestinal tract continuity. It must be regarded as an emergency condition that requires early diagnosis as well as very aggressive and rapid implementation of treatment in order to avoid serious complications and death. Methods of treatment for spontaneous esophageal perforation continue to be a matter of controversy. However, all authors emphasize that ultimate success depends largely on the time taken to establish the diagnosis. The authors of this study describe a rare case of duodenal ulcer perforation accompanied by Boerhaave syndrome. PMID:26702287

    Polychromatic synchrotron x-ray microbeams offer a very efficient alternative to electron beam methods for quantifying the amount and character of grain subdivision accompanying large deformations. With a 0.01 mm diameter collimator, bending magnet radiation from a 3.0 GeV source and image storage plates, samples of copper with thicknesses greater than 0.1 mm have been studied. Results from an as-received sample and a sample deformed to 100% torsion are compared and illustrate how efficiently grain subdivision can be quantified with polychromatic microbeam diffraction.

    To expose systematic trends in violin sound accompanying "tuning" only the plates or only the bridge, the first structural acoustics-based model auralizations of violin sound were created by passing a bowed-string driving force measured at the bridge of a solid body violin through the dynamic filter (DF) model radiativity profile "filter" RDF(f) (frequency-dependent pressure per unit driving force, free-free suspension, anechoic chamber). DF model auralizations for the more realistic case of a violin held/played in a reverberant auditorium reveal that holding the violin greatly diminishes its low frequency response, an effect only weakly compensated for by auditorium reverberation.

It is shown that depending on the power density of irradiation was observed a large scatter size of the microparticles. From a certain average power density is observed beginning oxidation particulate emitted from the surface of the irradiated area. By varying the parameters of the laser beam such as scanning speed, pulse repetition rate, overlap of laser spot, radiation dose can be achieved almost complete oxidation of all formed during the ablation of microparticles.

    One of the main requirements of the graduated driving licensing system in Israel is that new drivers be accompanied by an experienced driver (usually one of their parents) for the first three months after receipt of their license. The current series of studies examined the associations between young drivers' attitudes toward accompanied driving (ATAD) and their perception of their parents' driving styles and parenting modes, as well as dynamic of their family. Young drivers completed questionnaires assessing their ATAD, and either perceived parental driving style (Study 1, n=100), perceived parenting style (Study 2, n=120), or perceived family dynamic (Study 3, n=254). The results indicated significant associations between the young drivers' ATAD of tension, relatedness, avoidance, disapproval, and anxiety, and their own perceptions of the characteristic driving styles of their parents (risky, anxious, angry, and careful). They also indicated significant relationship between youngsters' ATAD and their perceptions of their parents' parenting modes (responsive, demanding, and autonomy-granting). Finally, the results indicated significant negative associations between ATAD of tension, avoidance, disapproval, and anxiety, and family cohesion and adaptability, and a positive association between these two and relatedness. The results are discussed in respect to the relationship between the parental model and the young drivers' ATAD in particular, and risk management in general, and practical implications of these results are offered.

    A suspension of heat-killed Mycobacterium tuberculosis in liquid paraffin has been reported to induce foot swelling accompanied by new bone formation in Buffalo (BUF) rats, which are low responders to the induction of adjuvant arthritis. In the present study, we found that wax D, a mycobacterial cell wall peptidoglycan fragment-arabinogalactan-mycolic acid complex, was an effective component of this bacterium for the induction of osteomyelitis accompanied by reactive bone formation in BUF rats. Chronic inflammation was produced in BUF rats by a single subcutaneous injection of wax D suspended in liquid paraffin. Other Mycobacterium species and Gordona bronchialis were also capable of inducing this reaction. Other bacterial cells including the acid-fast bacteria Nocardia and Rhodococcus, purified cell walls and peptidoglycans from Lactobacillus plantarum, wax C, cord factor, arabinogalactan and mycolic acid prepared from M. tuberculosis were inactive in this respect. In addition, when wax D was administered as a water-in-oil emulsion (Freund's type adjuvant), bone formation scarcely occurred in BUF rats. In Fisher (F344) and Wistar rats, both of which are responder strains to adjuvant arthritis, wax D in liquid paraffin did not induce bone formation. PMID:9879920

    Recent studies have demonstrated adaptive evolutionary responses to climate change, but little is known about how these responses may influence ecological interactions with other organisms, including natural enemies. We used a resurrection experiment in the greenhouse to examine the effect of evolutionary responses to drought on the susceptibility of Brassica rapa plants to a fungal pathogen, Alternaria brassicae. In agreement with previous studies in this population, we found an evolutionary shift to earlier flowering postdrought, which was previously shown to be adaptive. Here, we report the novel finding that postdrought descendant plants were also more susceptible to disease, indicating a rapid evolutionary shift to increased susceptibility. This was accompanied by an evolutionary shift to increased specific leaf area (thinner leaves) following drought. We found that flowering time and disease susceptibility displayed plastic responses to experimental drought treatments, but that this plasticity did not match the direction of evolution, indicating that plastic and evolutionary responses to changes in climate can be opposed. The observed evolutionary shift to increased disease susceptibility accompanying adaptation to drought provides evidence that even if populations can rapidly adapt in response to climate change, evolution in other traits may have ecological effects that could make species more vulnerable.

    Objective: To investigate cognitive dysfunction of type 2 diabetes patients accompanied with obstructive sleep apnea syndrome (OSAS), and to analyze its relevant characteristics. Methods: Total 115 type 2 diabetes patients were divided into OSAS group (O group, n=83) and non-OSAS group (N group, n=32); Physical examination patients (C1 group, n=64) and OSAS patients without diabetes (C2 group, n=47) served as the control group. Apnea-hypopnea index (AHI), nocturnal lowest saturation of pulse oxygen (LSPO2) and simple mental state examination scale (MMSE) were evaluated. Results: Among diabetes patients, patients with OSAS have lower glycated hemoglobin, platelet count, thrombocytocrit, MMSE score and lowest mean arterial oxygen than non-OSAS patients; cognitive dysfunction state and glycemic control of patients are related to their diabetic duration, and then along with increase of diabetic duration, glycemic control becomes poor, so that cognitive dysfunction becomes more and more obvious. Conclusion: Along with increased diabetic duration in type 2 diabetes accompanied with OSAS, glycemic control becomes poor, so that cognitive dysfunction more easily occurs. Meanwhile, coagulation function of blood system in OSAS patients with diabetes is impacted to some extent. PMID:25674144

    The enthalpy changes, {Delta}H, in suspensions of Li-, Na-, and K-montmorillonite were determined as functions of the molal concentrations of LiCl, NaCl, and KCl, respectively, by microcalorimetry. These changes were compared with the corresponding changes in interlayer distance, {lambda}, as determined by X-ray diffraction. It was found that {Delta}H values accompanying the collapse of the montmorillonite layers from {lambda} > 14 nm to {lambda} {approx_equal} 1.0 nm were essentially negligible; however, {Delta}H values accompanying the collapse of layers of Li- and Na-montmorillonite from {lambda} {approx_equal} 1.0 nm to {lambda} {approx_equal} 0.6 nm, and the collapse of layers of K-montmorillonite from {lambda} {approx_equal} 0.6 nm, were not negligible. No additional collapse of Li- and Na-montmorillonite layers occurred after {lambda} {approx_equal} 0.6 nm, and for K-montmorillonite layers after {lambda} {approx_equal} 0.3 nm, but {Delta}H continued to change with increasing salt addition. This change was attributed to the penetration of electrolyte into the interlayer space. A notable observation was that the value of {Delta}H was positive for Li-montmorillonite, but negative for Na- and K-montmorillonite. These observations were interpreted to mean that {Delta}H changes in the montmorillonite suspension were largely attributable to reorganization of the interlayer space by the added electrolytes.

    The transport of neutral molecules in electroactive polymer films is a problem of considerable importance and is addressed here for thin (ca. 10 nm thick) polythionine films. In weak acid media, pH < pK{sub HA}, both solvent and undissociated weak acid are present in the polymer. Raising the pH above pK{sub HA} progressively removes HA. Using the quartz crystal microbalance, we determined the film weight changes accompanying the redox switching process. At all pH's studied, a mass decrease accompanies reduction. The magnitude of this change is consistent with the expulsion of one water molecule per redox site where, at low pH, HA within the film acts as the sole source of counterion, A{sup {minus}}. At higher pH, counterions must increasingly be supplied by the bathing solution, with the result that the mass change becomes less negative. These results are interpreted from a purely thermodynamic viewpoint, and then we discuss a coordination model as a relevant, special case.

    Burst-mode focused ultrasound (FUS) induces microbubble cavitation in the vasculature and temporarily disrupts the blood-brain barrier (BBB) to enable therapeutic agent delivery. However, it remains unclear whether FUS-induced BBB opening is accompanied by neuromodulation. Here we characterized the functional effects of FUS-induced BBB opening by measuring changes in somatosensory evoked potentials (SSEPs) and blood-oxygen-level dependent (BOLD) responses. Rats underwent burst-mode FUS (mechanical index (MI) of 0.3, 0.55 or 0.8) to the forelimb region in the left primary somatosensory cortex to induce BBB opening. Longitudinal measurements were followed for up to 1 week to characterize the temporal dynamics of neuromodulation. We observed that 0.8-MI FUS profoundly suppressed SSEP amplitude and prolonged latency, and this effect lasted 7 days. 0.55-MI FUS resulted in minimal and short-term suppression of SSEP for less than 60 minutes and didn’t affect latency. BOLD responses were also suppressed in an MI-dependent manner, mirroring the effect on SSEPs. Furthermore, repetitive delivery of 0.55-MI FUS every 3 days elicited no accumulative effects on SSEPs or tissue integrity. This is the first evidence that FUS-induced BBB opening is accompanied by reversible changes in neuron responses, and may provide valuable insight toward the development of FUS-induced BBB opening for clinical applications.

  2. Changes in the linking number of supercoiled DNA accompany growth transitions in Escherichia coli.

    The supercoiling levels of plasmid DNA were determined from Escherichia coli which was grown in ways that are known to alter global patterns of gene expression and metabolism. Changes in DNA supercoiling were shown to occur during several types of these nutrient upshifts and downshifts. The most dramatic change in supercoiling was seen in starved cells, in which two populations of differentially relaxed plasmids were shown to coexist. Thus, some changes in the external nutritional environment that cause the cells to reorganize their global metabolism also cause accompanying changes in DNA supercoiling. Results of experiments with dinitrophenol suggested that the observed relaxations were probably not due to reduced pools of ATP. When rifampin was used to release supercoils restrained by RNA polymerase, the cellular topoisomerases responded by removing these new, unrestrained supercoils. We interpret these results as implying that the cellular topological machinery maintains a constant superhelical energy in the DNA except during certain growth transitions, when changes in metabolism and gene expression are accompanied by changes in DNA supercoiling.

    Among 440 adult patients with tibial shaft fracture and accompanying fibular fracture there were eight cases with radiographically ununited fibulae 4 months after the injury, each with uneventful tibial union. Fractures with severe soft-tissue injuries were excluded from this study. In 293 patients the treatment method of the tibial fracture was conservative, comprising closed reduction and immobilization by long plaster cast. In 147 patients it was intramedullary Küntscher nailing, and all the eight cases with delayed fibular union occurred among these, the frequency being 5.4%. The typical accompanying fibular fracture to develop delayed union was a comminuted one in the middle or distal third of the bone. At a followup examination 5 to 8 years after the original injury four of the eight fractures were found to have ultimately spontaneously united, while three showed a radiographically indisputable nonunion. One patient had undergone segmental fibular ostectomy because of persistent local pain but in the remaining patients the subjective symptoms were negligible. The occurrence of delayed fibular union in association with rigid intramedullary nailing of concomitant tibial shaft fracture is a phenomenon of which trauma surgeons should be aware even if the natural course of the condition often seems to be benign.

    Plant foliar uptake and translocation is an important pathway for the migration of radiocesium to the human diet. This study reports the effects of accompanying anions ( [Formula: see text] , [Formula: see text] , [Formula: see text] , and I(-)) on cesium retention and translocation. An experiment to simulate cesium retention and translocation was conducted in a greenhouse by applying droplets of stable cesium solutions to the upper surface of four soybean [Glycine max (L.) Merr.] trifoliate leaves. The average percentages of cesium retention with the accompanying anions [Formula: see text] , [Formula: see text] , [Formula: see text] , and I(-) on the leaves were 7.2, 21.5, 49.3, and 10.2%, respectively. Retention values of the four treatments were stable during the 3-day exposure period, indicating that cesium could be absorbed and penetrate the cuticle quickly once it was dissolved. Scanning electron microscopy coupled with energy dispersive X-ray microanalysis showed that particles containing cesium remained on the leaf surfaces after washing. Also, nano-sized particles containing cesium were observed inside the leaf tissues. Cesium concentrations in the uncontaminated leaves, pods, stems, and roots increased during the study period indicating cesium redistribution from the contaminated leaves. PMID:24063906

    The paper defines the therapeutic and rehabilitation approach to the patients with Angle's classification Class II dento-facial anomalies, accompanied by obstructive sleep apnea (OSA). The proposed comprehensive approach to the diagnostics and treatment of patients with posterior occlusion, accompanied by OSA, allows for objective evaluation of intensity of a dento-facial anomaly and accompanying respiratory disorders in the nasal and oral pharynx, which allows for the pathophysiological mechanisms of OSA to be identified, and an optimal plan for surgical procedures to be developed. The proposed comprehensive approach to the diagnostics and treatment of patients with Angle's classification Class II dento-facial anomalies provides high functional and aesthetic results.

    This paper mainly deals with the optimal control of an accompanying satellite (AS) rotating around the space station (SS). The concept of AS around the SS is introduced. Both the AS and the SS are modeled as rigid bodies with the reference coordinate frames described for the AS pointing to the SS according to different missions. Then the paper designs an optimal control law with the full set of nonlinear equations of motion derived by using unit quaternion. These equations are solved numerically using direct transcription method to obtain optimal solution for the underactuated satellite. The analytical and simulation results show that the proposed control law is effective in the case of failed actuators.

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate. ARDS accompanied by AOSD has been rarely reported in the literature. In conclusion, in a patient with ARDS who does not respond to antibiotic treatment, the involvement of AOSD should be considered.

    Understanding the underlying mechanisms involved in graphene growth via chemical vapour deposition (CVD) is critical for precise control of the characteristics of graphene. Despite much effort, the actual processes behind graphene synthesis still remain to be elucidated in a large number of aspects. Herein, we report the evolution of graphene properties during in-plane growth of graphene from reduced graphene oxide (RGO) on copper (Cu) via methane CVD. While graphene is laterally grown from RGO flakes on Cu foils up to a few hundred nanometres during CVD process, it shows appreciable improvement in structural quality. The monotonous enhancement of the structural quality of the graphene with increasing length of the graphene growth from RGO suggests that seeded CVD growth of graphene from RGO on Cu surface is accompanied by the restoration of graphitic structure. The finding provides insight into graphene growth and defect reconstruction useful for the production of tailored carbon nanostructures with required properties. PMID:26961409

    Breast cancer is the most common cancer type for women in the western world. Despite decades of research, the molecular processes associated with breast cancer progression are still inadequately defined. Here, we focus on the systematic alteration of metabolism by using the state of the art metabolomic profiling techniques to investigate the changes of 157 metabolites during the progression of normal mouse mammary epithelial cells to an isogenic series of mammary tumor cell lines with increasing metastatic potentials. Our results suggest a two-step metabolic progression hypothesis during the acquisition of tumorigenic and metastatic abilities. Metabolite changes accompanying tumor progression are identified in the intracellular and secreted forms in several pathways, including glycolysis, the tricarboxylic acid cycle, the pentose phosphate pathway, fatty acid and nucleotide biosynthesis, and the GSH-dependent antioxidative pathway. These results suggest possible biomarkers of breast cancer progression as well as opportunities of interrupting tumor progression through the targeting of metabolic pathways. PMID:20139083

    It has been found that powerful cyclones are proceeded, accompanied and followed by narrow band electromagnetic emission with central frequency around 2 Hz. It is shown that the signal from this emission is unique and clearly distinguishable from known types of magnetic pulsations, spectra of local thunderstorms, and signals from industrial sources. This emission was first observed during an unusually powerful cyclone with tornadoes in the western European part of the Soviet Union, which passed by the observatory of Borok from south to north-east. The emission has been confirmed by analysis of similar events in Antarctica. The phenomenon described presents a new aspect of interactions of processes in the lower atmosphere and the ionosphere.

    Shipibo Indians, who formed a village to establish a school and health clinic, are gradually depleting local fish and game resources. Men, recently adopting rice as a cash crop, tend to fish and hunt less than other men working only their subsistence gardens. Sale of fish and game in the village is becoming common, and pigs, once raised exclusively for sale to non-Shipibo, are now more regularly eaten and used for attracting agricultural labor. Other research has indicated that cash cropping often competes for workers' time in subsistence and so dietary change usually accompanies changing activity patterns. This paper explores the latter possibility by examining the relationship between cash cropping, wild meat procurement, and diet among the Shipibo. Time allocation and food consumption data are analyzed statistically to test a mathematical theory and model which relates indigenous work patterns to diet.

    A diffraction experiment using high-energy X-rays was carried out on YbInCu4. Below the Yb valence transition temperature, the splitting of Bragg peaks was detected in high-order reflections. No superlattice reflections accompanying the valence ordering were found below the transition temperature. These experimental findings indicate that a structural change from a cubic structure to a tetragonal structure without valence ordering occurs at the transition temperature. Such a structural change free from any valence ordering is difficult to understand only in terms of Yb valence degrees of freedom. This means that the structural change may be related to electronic symmetries such as quadrupolar degrees of freedom as well as to the change in Yb valence.

    Background HDR syndrome (hypoparathyroidism, sensorineural deafness and renal disease) is an autosomal dominant condition, defined by the triad hypoparathyroidism, renal dysplasia and hearing loss. Hirschsprung (HSCR) disease is a variable congenital absence of ganglion cells of the enteric nervous system resulting in degrees of functional bowel obstruction. Rarer chromosomal anomalies are reported in combination with Hirschsprung disease like DiGeorge syndrome, mosaic trisomy 8, XXY chromosomal constitution, partial duplication of chromosome 2q, tetrasomy 9p, and 20p deletion. Case Presentation Here, we describe an 8 year-old girl with HDR syndrome accompanied by Hirschsprung disease. Although the association of Hirschsprung disease with chromosomal anomalies has been reported, according to our knowledge, this is the first report of associated HSCR with HDR syndrome.

    A semimicroscopic approach based on the continuum version of the random-phase approximation (CRPA) and on a semiphenomenological inclusion of the fragmentation effect is applied to describing cross sections for photoabsorption and direct plus semidirect and inverse reactions accompanied by the excitation of isovector giant dipole and quadrupole resonances. In addition to the spinless part of the Landau-Migdal interaction and a partly self-consistent phenomenological mean field of the nucleus, that version of the approach which is used here takes into account isovector separable velocity-dependent forces, as well as the effect of the fragmentation shift of the giant-resonance energy. The results obtained by calculating various features of the aforementioned cross sections for a number of magic and semimagic medium-mass nuclei are compared with respective experimental data.

    Many issues in DNA barcoding need to be solved before it can reach its goal to become a general database for species identification. While species delimitations are more or less well established in several taxa, there are still many groups where this is not the case. Without the proper taxonomic background/knowledge and corroboration with other kinds of data, the DNA barcoding approach may fail to identify species accurately. The classification and taxonomy of phylum Nemertea (nemerteans, ribbon worms) are traditionally based on morphology, but are not corroborated by an increasing amount of genetic data when it comes to classification either into species or into higher taxa. The taxonomy of the phylum needs to be improved before the full potential of DNA barcoding can be utilized to make sure that valid Linnean names accompany the barcode sequences. We illustrate the problematic situation in the phylum Nemertea by a case study from the genus Cerebratulus. PMID:21565022

    The human brain's executive systems play a vital role in deciding and selecting among actions. Selection among alternatives also occurs in the perceptual domain, for instance when perception switches between interpretations during perceptual bistability. Whether executive systems also underlie this functionality remains debated, with known fronto-parietal concomitants of perceptual switches being variously interpreted as reflecting the switches' cause, or as reflecting their consequences. We developed a paradigm where the two eyes receive different inputs and perception demonstrably switches between these inputs, yet where switches themselves are so inconspicuous as to become unreportable, minimizing their executive consequences. Fronto-parietal fMRI BOLD responses that accompany perceptual switches were similarly minimized in this paradigm, indicating that these reflect the switches' consequences rather than their cause. We conclude that perceptual switches do not always rely on executive brain areas, and that processes responsible for selection among alternatives may operate outside of the brain's executive systems.

    As part of an ethnographic study, the impact of foreign postings on spouses who accompany military personnel was explored. Individual interviews and focus groups with 34 British military spouses based in one location in southern Europe were conducted. Key findings suggested that reaction to a foreign posting was a reflection of personal attitudes, prior experiences, support, ability to adjust to change and strength of relationship with the serving spouse and community. For many the experience was positive due to the increased opportunity for family time, for others this helped to compensate for the difficulties experienced. Some military spouses experienced significant distress on the posting, particularly if the family was not well-supported. The potential implications of military spouses not adapting to foreign postings have significant implications for healthcare practice. Provision of more appropriate support resources before and during the posting would facilitate the transition for the military spouse and their family. PMID:26973933

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. PMID:27600056

    During vesicle budding or endocytosis, biomembranes undergo a series of lipid- and protein-mediated deformations involving cholesterol-enriched lipid rafts. If lipid rafts of high bending rigidities become confined to the incipient curved membrane topology such as a bud-neck interface, they can be expected to reform as ring-shaped rafts. Here, we report on the observation of a disk-to-ring shape morpho-chemical transition of a model membrane in the absence of geometric constraints. The raft shape transition is triggered by lateral compositional heterogeneity and is accompanied by membrane deformation in the vertical direction, which is detected by height-sensitive fluorescence interference contrast microscopy. Our results suggest that a flat membrane can become curved simply by dynamic changes in local chemical composition and shape transformation of cholesterol-rich domains. PMID:26053547

    We present a 52-year-old male with a syphilitic aortic arch aneurysm accompanied by relevant extensive cerebral infarction. He was admitted to a local hospital for sudden loss of consciousness, where he was diagnosed with serious cerebral infarction. During his treatment, a multilocular aortic arch aneurysm involving the arch vessels was found incidentally. He was transferred to our hospital for surgical treatment. A preoperative routine laboratory test for syphilis was highly positive, which suggested that the aneurysm was likely caused by syphilis and the cerebral infarction was also induced by the involvement of syphilitic aortitis or arteritis. After 2 weeks of antibiotic therapy for syphilis, total arch replacement was performed successfully using meticulous brain protection with antegrade selective cerebral perfusion and deep hypothermia. He recovered without any further cerebral deficits. The pathological examination of the surgical specimen showed some characteristic changes of syphilitic aortitis. PMID:24492165

    Laryngeal sarcocystosis is an uncommon zoonotic coccidian protozoal infestation of human beings. The authors reviewed the pathology of 1,063 laryngeal biopsies over the past 10 years (2000 to 2009). Only one case of laryngeal sarcocystosis accompanying laryngeal squamous cell carcinoma was identified. The overall prevalence of laryngeal sarcocystosis was 0.094%. The case was a 66-year-old man who presented with voice hoarseness for six months. Physical examination and computed tomography revealed an ulcerative exophytic mass on the right true vocal cord, suggestive of laryngeal carcinoma. He underwent a right frontolateral partial laryngectomy. Histopathology showed a nonkeratinizing squamous cell carcinoma with Sarcocystis spp in the vocalis muscle. He was followed up and enrolled in speech therapy. The authors briefly review the clinicopathologic features and pathogenesis of muscular sarcocystosis and concurrent laryngeal sarcocystosis and squamous cell carcinoma. PMID:22299431

    We examined whether Meckel's cartilage of embryonic mice, 17 days in utero, undergo the cellular transformation into the osteocyte-like phenotype under organ culture conditions. Explants were grown by our original pithole method modified Trowell-type cultures for up to 4 weeks at 37 degrees C under 5% CO2 in air. Specimens were examined using histological procedures including immunostaining and electron microscopy. In addition, the effects of beta-glycerophosphate on matrix calcification were also examined in cultures with or without beta-glycerophosphate. Addition of beta-glycerophosphate induced calcification at a higher level, but calcium mineral deposition occurred regardless of the addition of beta-glycerophosphate to the culture medium. Light and electron microscopic analyses showed that freshly isolated chondrocytes prior to cell culture had typical hypertrophic morphology, but shortly after commencement of culture, they showed morphological modifications. The cells showing chondrocytic phenotypes became basophilic elliptical cells, and eventually transformed into flattened osteocyte-like cells. Bone-like features for cellular elements were characterized by spindle-shaped cells with elongated processes accompanying bone-specific thick-banded collagen fibrils. Immunostaining showed that at 2 weeks in culture, type I and type II collagens coexisted in the matrix, but subsequently type II collagen synthesis ceased and was replaced by type I collagen synthesis. Immunofluorescent labeling for osteocalcin was noted first in the peripheral cells by 1 week, but at 3 weeks this reaction spread to the central zone in explants. Alkaline phosphatase activity (ALPase) was expressed on the cells in the central zone prior to calcium mineral deposition as shown by von Kossa's reaction at 3 weeks in culture. These results showed that Meckel's cartilage chondrocytes in organ culture synthesize bone-type proteins accompanying osteocytic phenotype expression. PMID:8838497

    The present study examined the effects of buprenorphine (BUP), a mixed opioid agonist-antagonist, on the behaviors accompanying cocaine (COCA) and combined cocaine-ethanol (EtOH) toxicity in the surviving mice. Using the activity-counting instrument Supermex, the relationship between the toxic signs and the corresponding behavioral alterations could be assessed. In the COCA-only group, a prolonged increase in the activity counts was caused by a high dose of COCA (75 mg/kg ip). Furthermore, this COCA-induced hyperactivity included ataxic behaviors that were accompanied by visible toxic signs, which were not observed in the mice with no drug treatment. A depressive dose of EtOH (3 g/kg ip) did not significantly modify the mortality rate in the COCA-only group in spite of its anticonvulsant effects. However, the peak activity counts in the survivors were attenuated in the COCA-EtOH group as compared to the COCA-only group. BUP attenuated the mortality rate in both COCA and COCA-EtOH groups, even without any anticonvulsant effects, but the most effective dose differed between the COCA (BUP: 0.25 mg/kg ip) and COCA-EtOH (BUP: 0.5 mg/kg ip) groups. At these BUP doses, the prolonged suppression of the morbid hyperactivity in the COCA-BUP group and the restoration of normal behavior in the COCA-EtOH-BUP group both seemed to be correlated with a good prognosis in the survivors; there was an early recovery from an increased blood pressure (BP), increased heart rate (HR) and decreased respiratory rate (RR) in the COCA-BUP group, and an early recovery from a decreased BP, decreased HR and decreased RR in the COCA-EtOH-BUP group.

    Letrozole (LTZ), one of ovulation induction medications, is increasingly prescribed in many gynecological conditions. Although its hazardous effect on the ovarian surface epithelium (OSE) as well as tubal epithelium cells (TEC) has been previously studied, the associated changes occurring in the inflammatory cytokines have not been elucidated. Therefore, the objective of our study is to investigate these changes that may accompany LTZ-induced tubo-ovarian epithelial abnormalities. A total of 45 Sprague-Dawley rats were used in this study, divided equally into; control, LTZ6 and LTZ12 groups (received saline, 6 and 12 cycles LTZ i.p. respectively). Samples from ovaries (OVs) as well as fallopian tubes (FTs) were histologically studied for the associated changes. An increased proliferative activity, Ki67 immunoexpression and abnormal invaginations were observed in the OSE of LTZ6 group accompanied with occasional pseudostratification and loss of cilia of TEC. These changes became more pronounced in the LTZ12 where micropapillae, hyperchromasia, frequent deep invaginations, cysts of OSE as well as papillae and multilayering of TEC were noticed. The tubal level of IL-1β, IL-6, TNF-α and serum MCP-1 progressively increased in LTZ6 and LTZ12 groups compared with the control group. The significant positive correlation observed between these cytokines in the LTZ6 group became stronger in the LTZ12 one. However, no significant changes in the tubal IL-10 and TGF-β were detected. Therefore, further studies are required to consider these cytokines as objective markers to precisely assess severity of the associated epithelial changes particularly in long periods of stimulation.

    Objective: Thyroid pathologies and non-medullary thyroid cancer often accompany primary hyperparathyroidism (PHPT). The purpose of this study was to examine the association between thyroid diseases, especially micropapillary thyroid cancer, with PHPT. Material and Methods: Data regarding 46 patients who were operated on with a diagnosis of PHPT at Inonu University Faculty of Medicine, General Surgery Clinic between June 2009 and March 2013 were retrospectively analyzed. Age, gender, levels of preoperative calcium, parathyroid hormone and phosphorus, and the histopathological results of the removed parathyroid and thyroid tissues were evaluated. All of the patients had a preoperative diagnosis of PHPT and there was no history of radiation to the head and neck region in any of the patients. Results: Out of the 46 patients who were operated on for PHPT, 39 were female and 7 were male. The mean age was 52.8 years (25–76). Simultaneous thyroidectomy was performed in 35 patients (76.1%) due to an accompanying thyroid disorder. Papillary microcarcinoma was detected in 5 of these 35 (10.9%) patients who underwent thyroidectomy, two of which (40%) were multifocal tumors. The benign thyroid pathologies detected in the remaining 30 (65.2%) cases included lymphocytic thyroiditis in 3, Hashimoto thyroiditis in 1, follicular adenoma in 3 (two of which was Hurtle cell), and nodular colloidal goiter in 23 patients. The preoperative serum phosphate level was significantly higher in the group with papillary thyroid microcarcinoma (p=0.013). Conclusion: In regions where goiter is endemic, thyroid diseases and thyroid papillary microcarcinoma occur in association with PHPT at a higher rate compared to the normal population. Therefore, we believe that patients who are planned for surgery due to PHPT should be thoroughly investigated for the presence of any concomitant malignant thyroid pathologies in the preoperative period. It should also be kept in mind that patients with high

    The aim of this study was to describe and analyze gross and fine motor function and accompanying neurological impairments in children with cerebral palsy (CP) born between 1991 and 1998 in western Sweden. A population-based study comprised 411 children with a diagnosis of CP ascertained at 4 to 8 years of age. Gross Motor Function Classification System (GMFCS) levels were documented in 367 children (205 males, 162 females). Bimanual Fine Motor Function (BFMF) classification levels of 345 of the children and information on learning disability, epilepsy, visual and hearing impairments, and hydrocephalus from 353 children were obtained. For spastic CP, a new classification according to the Surveillance of Cerebral Palsy in Europe of uni- and bilateral spastic CP was applied. GMFCS was distributed at Level I in 32%, Level II in 29%, Level III in 8%, Level IV in 15%, and Level V in 16%. The corresponding percentages for BFMF were 30.7%, 31.6%, 12.2%, 11.9%, and 13.6% respectively. Learning disability was present in 40%, epilepsy in 33%, and severe visual impairment in 19% of the children. Motor function differed between CP types. More severe GMFCS levels correlated with larger proportions of accompanying impairments and, in children born at term, to the presence of adverse peri/neonatal events in the form of intracranial haemorrhage/stroke, cerebral infection, and hypoxic-ischaemic encephalopathy. GMFCS Level I correlated positively to increasing gestational age. We conclude that the classification of CP should be based on CP type and motor function, as the two combine to produce an indicator of total impairment load. PMID:16700930

    This study probed the mechanisms underlying microwave-induced alterations of thermoregulatory behavior. Adult male squirrel monkeys (Saimiri sciureus), trained to regulate the temperature of their immediate environment (Ta) behaviorally, were chronically implanted with Teflon reentrant tubes in the medical preoptic/anterior hypothalamic area (PO/AH), the brainstem region considered to control normal thermoregulatory processes. A Vitek temperature probe inserted into the tube measured PO/AH temperature continuously while changes in thermoregulatory behavior were induced by either brief (10-min) or prolonged (2.5-h) unilateral exposures to planewave 2,450-MHz continuous wave (CW) microwaves (E polarization). Power densities explored ranged from 4 to 20 mW/cm2 (rate of energy absorption (SAR) . 0.05 (W/kg)/cm2)). Rectal temperature and four representative skin temperatures were also monitored, as was the Ta selected by the animal. When the power density was high enough to induce a monkey to select a cooler Ta (8 mW/cm2 and above), PO/AH temperature rose approximately 0.3 degrees C but seldom more. Lower power densities usually produced smaller increases in PO/AH temperature and no reliable change in thermoregulatory behavior. Rectal temperature remained constant while PO/AH temperature rose only 0.2-0.3 degrees C during 2.5-h exposures at 20 mW/cm2 because the Ta selected was 2-3 degrees C cooler than normally preferred. Sometimes PO/AH temperature increments greater than 0.3 degrees C were recorded, but they always accompanied inadequate thermoregulatory behavior. Thus, a PO/AH temperature rise of 0.2-0.3 degrees C, accompanying microwave exposure, appears to be necessary and sufficient to alter thermoregulatory behavior, which ensures in turn that no greater temperature excursions occur in this hypothalamic thermoregulatory center.

    Background Apnea of Prematurity (AOP) is common, affecting the majority of infants born at <34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH). Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP), injury to sympathetic ganglia regulating cardiovascular action, impaired pancreatic islet cell and bone development, cerebellar injury, and neurodevelopmental disabilities. Current standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and methylxanthine therapy; these interventions are inadequate, and not optimal for early development. Objective The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements trigger reflexive facilitation of breathing. Methods Premature infants (23–34 wks gestational age), with clinical evidence of AOP/IH episodes were enrolled 1 week after birth. Caffeine treatment was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected. Results Fewer respiratory pauses occurred during vibration periods, relative to baseline (p<0.005). Significantly fewer SpO2 declines occurred with vibration (p<0.05), relative to control periods. Significantly fewer bradycardic events occurred during vibration periods, relative to no vibration periods (p<0.05). Conclusions In premature neonates, limb proprioceptive stimulation, simulating limb movement, reduces breathing pauses and IH episodes, and lowers the number of bradycardic events that accompany aberrant breathing episodes. This low-cost neuromodulatory procedure has the potential to provide a non

    Negative cortical DC shifts preceding and accompanying the execution of four different motor tasks were analysed in 18 subjects (Ss): Repetitive flexions and extensions of the forefinger had to be performed either by the right (1) or the left (2) hand. This simple motor task was compared to a complex one in which flexions and extensions of forefinger and hand had to be alternated in a fixed sequence. The complex task had either to be performed by the right (3) or the left (4) hand. Thus, the four conditions differed in the side of the performing hand (right/left) and in task-complexity (simple/complex). After its voluntary initiation, each task had to be performed for at least a period of six seconds. A Bereitschaftspotential (BP) preceded the voluntary initiation of the movement. Task-performance was accompanied by a negative DC shift called a performance-related negativity (N-P). Amplitudes of BP and N-P were compared by analysis of variance (ANOVA) using the factors "performing hand" (right/left) and "task-complexity" (simple/complex). "Performing hand" had significant effects on N-BP and N-P in C3* and C4* (positioned over the primary motor cortex) but did not influence mid-central (Cz*), frontal (F3, Fz, and F4) or parietal (P3, Pz, P4) recordings. "Task-complexity" had significant effects on N-P in mid-central (Cz*, C1*, C2*) and parietal (P3, Pz) recordings with higher negativity for complex movements. Recordings in C3* and C4* did not vary with "task complexity".(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2924844

    AIM: To evaluate the efficacy of water supplementation treatment in patients with functional dyspepsia or irritable bowe syndrome (IBS) accompanying predominant constipation. METHODS: A total of 3 872 patients with functional dyspepsia and 3 609 patients with irritable bowel syndrome were enrolled in the study by 18 Italina thermal centres. Patients underwent a first cycle of thermal therapy for 21 d. A year later patients were re-evaluated at the same centre and received another cycle of thermal therapy. A questionnare to collect personal data on social and occupational status, family and pathological case history, life style, clinical records, utilisation of welfare and health structure and devices was administered to each patient at basal time and one year after each thermal treatment. Sixty patients with functional dyspepsia and 20 with IBS and 80 healthy controls received an evaluation of gastric output and oro-cecal transit time by breath test analysis. Breath test was performed at basal time and after water supplementaton therapies. Gastrointestinal symptoms were evaluated at the same time points. Breath samples were analyzed with a mass spectometer and a gascromatograph. Results were expressed as T1/2 and T-lag for octanoic acid breath test and as oro-cecal transit time for lactulose breath test. RESULTS: A significant reduction of prevalence of symptoms was observed at the end of the first and second cycles of thermal therapy in dyspeptic and IBS patients. The analysis of variance showed a real and persistant improvement of symptoms in all patients. After water supplementation for 3 wk a reduction of gastric output was observed in 49 (87.5%) of 56 dyspeptic patients. Both T1/2 and T-lag were significantly reduced after the therapy compared to basal values [91 ± 12 (T1/2) and 53 ± 11 (T-lag), Tables 1 and 2] with results of octanoic acid breath test similar to healthy subjects. After water supplementation for 3 wk oro-cecal transit time was

    We aim to test the feasibility of using near-infrared spectroscopy (NIRS) for indirect measurement of human saliva secretion in response to taste stimuli for potential application to organoleptic testing. We use an NIRS system to measure extracranial hemodynamics (Hb-signals around the temples) of healthy participants when taste stimuli are taken in their mouths. First, the Hb-signals and volume of expelled saliva (stimulated by distilled-water or sucrose-solution intake) are simultaneously measured and large Hb-signal changes in response to the taste stimuli (Hb-responses) are found. Statistical analysis show that both the Hb response and saliva volume are larger for the sucrose solution than for the distilled water with a significant correlation between them (r = 0.81). The effects of swallowing on the Hb-signals are investigated. Similar Hb responses, differing from the sucrose solution and distilled water, are obtained even though the participants swallow the mouth contents. Finally, functional magnetic resonance imaging is used to identify possible sources of the Hb signals corresponding to salivation. Statistical analysis indicates similar responses in the extracranial regions, mainly around the middle meningeal artery. In conclusion, the identified correlation between extracranial hemodynamics and the saliva volume suggests that NIRS is applicable to the measurement of hemodynamic signals accompanying stimulated saliva secretion.

    The Swift-discovered GRB 080319B was by far the most distant source ever observed at naked-eye brightness, reaching a peak apparent magnitude of 5.3 at a redshift of z = 0.937. We present our late-time optical (Hubble Space Telescope, Gemini, and Very Large Telescope) and X-ray (Chandra) observations, which confirm that an achromatic break occurred in the power-law afterglow light curve at {approx}11 days post-burst. This most likely indicates that the gamma-ray burst (GRB) outflow was collimated, which for a uniform jet would imply a total energy in the jet E{sub jet} {approx}> 10{sup 52} erg. Our observations also show a late-time excess of red light, which is well explained if the GRB was accompanied by a supernova (SN), similar to those seen in some other long-duration GRBs. The latest observations are dominated by light from the host and show that the GRB took place in a faint dwarf galaxy (r(AB) {approx} 27.0, rest frame M{sub B} {approx} -17.2). This galaxy is small even by the standards of other GRB hosts, which is suggestive of a low-metallicity environment. Intriguingly, the properties of this extreme event-a small host and bright SN-are entirely typical of the very low luminosity bursts such as GRB 980425 and GRB 060218.

    New experiences can trigger changes in gene expression in the brain. To understand this phenomenon better, we studied zebra finches hearing playbacks of birdsong. Earlier research had shown that initial playbacks of a novel song transiently increase the ZENK (ZIF-268, EGR1, NGFIA, KROX-24) mRNA in the auditory forebrain, but the response selectively habituates after repetition of the stimulus. Here, using DNA microarray analysis, we show that novel song exposure induces rapid changes in thousands of RNAs, with even more RNAs decreasing than increasing. Habituation training leads to the emergence of a different gene expression profile a day later, accompanied by loss of essentially all of the rapid “novel” molecular responses. The novel molecular profile is characterized by increases in genes involved in transcription and RNA processing and decreases in ion channels and putative noncoding RNAs. The “habituated” profile is dominated by changes in genes for mitochondrial proteins. A parallel proteomic analysis [2-dimensional difference gel electrophoresis (2D-DIGE) and sequencing by mass spectrometry] also detected changes in mitochondrial proteins, and direct enzyme assay demonstrated changes in both complexes I and IV in the habituated state. Thus a natural experience, in this case hearing the sound of birdsong, can lead to major shifts in energetics and macromolecular metabolism in higher centers in the brain. PMID:19541599

  20. Two sources of meaning in infant communication: preceding action contexts and act-accompanying characteristics.

    2014-09-19

    How do infants communicate before they have acquired a language? This paper supports the hypothesis that infants possess social-cognitive skills that run deeper than language alone, enabling them to understand others and make themselves understood. I suggested that infants, like adults, use two sources of extralinguistic information to communicate meaningfully and react to and express communicative intentions appropriately. In support, a review of relevant experiments demonstrates, first, that infants use information from preceding shared activities to tailor their comprehension and production of communication. Second, a series of novel findings from our laboratory shows that in the absence of distinguishing information from preceding routines or activities, infants use accompanying characteristics (such as prosody and posture) that mark communicative intentions to extract and transmit meaning. Findings reveal that before infants begin to speak they communicate in meaningful ways by binding preceding and simultaneous multisensory information to a communicative act. These skills are not only a precursor to language, but also an outcome of social-cognitive development and social experience in the first year of life. PMID:25092662

    A 53-year-old woman was admitted to our hospital because of high fever and abnormal chest radiograph shadows. Chest X-ray on admission showed a nodular shadow in the right upper lung field and a mass shadow with a cavity in the left middle lung field. Laboratory data indicated leukocytosis and elevation of C-reactive protein. Pulmonary suppuration was suspected, panipenem/betamipron was prescribed, but a mass and consolidation developed, and the medication was changed to ciprofloxacin. Convulsive seizures with loss of consciousness appeared after the change to ciprofloxacin. Lumbar puncture revealed pleocytosis with a predominance of mononuclear cells (198/3) and elevated protein(83 mg/dl). Brain CT showed no abnormal image, and acute aseptic meningitis was diagnosed and was treated with cefotaxime, clindamycin, fluconazole, acicrovir and sulfamethoxazole/trimethoprim. However, the treatment did not result in symptomatic improvement, and brain MRI showed intracranial disorders. Serum PR3-ANCA was elevated to 15 U/ml. Taken together with chest X-ray, sinusitis and clinical course, a generalized form of Wegener's granulomatosis was diagnosed. She was given 60 mg/day of prednisolone, 100 mg/day of cyclophosphamide and 9 g/day of sulfamethoxazole-trimethoprim and progressively improved. In this process, enhanced MR images showed thickened dural enhancement of the falx and bilateral anterior regions, which showed improvement on brain MRI at 8 months after starting treatment. We report a rare case of Wegener's granulomatosis accompanied with pachymeningitis and white matter lesions. PMID:15912757

    Gamma-ray burst (GRB) afterglows are likely produced in the shock that is driven as the GRB jet interacts with the external medium. Long-duration GRBs are also associated with powerful supernovae (SNe). We consider the optical and radio afterglows of long GRBs for both blasts viewed along the jet axis (`on-axis' afterglows) and misaligned observes (`off-axis' afterglows). Comparing the optical emission from the afterglow with that of the accompanying SN, using SN 1998bw as an archetype, we find that only a few per cent of afterglows viewed off-axis are brighter than the SN. For observable optical off-axis afterglows, the viewing angle is at most twice the half-opening angle of the GRB jet. Radio off-axis afterglows should be detected with upcoming radio surveys within a few hundred Mpc. We propose that these surveys will act as `radio triggers', and that dedicated radio facilities should follow-up these sources. Follow-ups can unveil the presence of the radio SN remnant, if present. In addition, they can probe the presence of a mildly relativistic component, either associated with the GRB jet or the SN ejecta, expected in these sources.

    In this study, we utilized observational methods to identify maternal values and concerns accompanying contraceptive use advice in Latina mother-daughter sexuality conversations. The sample included non-sexually active early adolescents around 12 years of age and their mostly Spanish-speaking Latina mothers. Videotaped conversations were coded for the prevalence of messages related to four sexual values (abstinence, delay sex until older, sex is "normal", sex is "improper") and concerns about pregnancy and STD transmission. We examined whether the duration of time spent conversing about these messages was associated with participant characteristics, general communication openness, and the amount of time the dyads spent discussing contraceptive use. Results indicated that Latina mothers who had fewer years of education and lower family income talked longer to their daughters about the need to delay sex, avoid risky situations that would increase their chances of getting pregnant or acquiring an STD, and engage in self-protective practices. Less perceived openness in general communication as reported by both the mothers and the daughters was associated with increased time discussing that sex is improper. Although the duration of contraceptive use messages was brief, mothers and daughters who discussed the fact that sex is normal, and who communicated more about the importance of delaying sex, talked longer about contraceptive use practices compared to mothers and daughters who engaged in minimal discussion of these sexual values.

    We present the first case of an intraductal papillary neoplasm of the bile duct (IPNB) accompanying a mixed adenoneuroendocrine carcinoma (MANEC). A 74-year-old woman presented with fever of unknown cause. Laboratory data revealed jaundice and liver injury. Contrast-enhanced computed tomography revealed a 20 mm polypoid tumor in the dilated distal bile duct, which exhibited early enhancement and papillary growth. Upper gastrointestinal endoscopy revealed mucus production from the papilla of Vater, characterized by its protruding and dilated orifice. Endoscopic ultrasonography visualized the polypoid tumor in the distal bile duct, but no invasive region was suggested by diagnostic imaging. Therefore, the initial diagnosis was IPNB. After endoscopic nasobiliary drainage, a pylorus-preserving pancreaticoduodenectomy was performed. Pathological examination of the resected bile duct revealed papillary proliferation of biliary-type cells with nuclear atypia, indicating pancreaticobiliary-type IPNB. In addition, solid portions comprised of tumor cells with characteristic salt-and-pepper nuclei were evident. Immunohistochemistry revealed expression of the neuroendocrine marker synaptophysin in this solid component, diagnosing it as a neuroendocrine tumor (NET). Furthermore, the MIB-1 proliferation index of NET was higher than that of IPNB, and microinvasion of the NET component was found, indicating neuroendocrine carcinoma (NET G3). This unique case of MANEC, comprising IPNB and NET, provides insight into the pathogenesis of biliary NET. PMID:23716999

    Recent work has demonstrated that allopolyploid speciation in plants may be associated with non-Mendelian genomic changes in the early generations following polyploid synthesis. To address the question of whether rapid genomic changes also occur in allopolyploid cotton (Gossypium) species, amplified fragment length polymorphism (AFLP) analysis was performed to evaluate nine sets of newly synthesized allotetraploid and allohexaploid plants, their parents, and the selfed progeny from colchicine-doubled synthetics. Using both methylation-sensitive and methylation-insensitive enzymes, the extent of fragment additivity in newly combined genomes was ascertained for a total of approximately 22,000 genomic loci. Fragment additivity was observed in nearly all cases, with the few exceptions most likely reflecting parental heterozygosity or experimental error. In addition, genomic Southern analysis on six sets of synthetic allopolyploids probed with five retrotransposons also revealed complete additivity. Because no alterations were observed using methylation-sensitive isoschizomers, epigenetic changes following polyploid synthesis were also minimal. These indications of genomic additivity and epigenetic stasis during allopolyploid formation provide a contrast to recent evidence from several model plant allopolyploids, most notably wheat and Brassica, where rapid and unexplained genomic changes have been reported. In addition, the data contrast with evidence from repetitive DNAs in Gossypium, some of which are subject to non-Mendelian molecular evolutionary phenomena in extant polyploids. These contrasts indicate polyploid speciation in plants is accompanied by a diverse array of molecular evolutionary phenomena, which will vary among both genomic constituents and taxa. PMID:11444689

    The Chiari malformation is an infrequently detected congenital anomaly characterized by the downward displacement of the cerebellum with a tonsillar herniation below the foramen magnum that may be accompanied by either syringomyelia or hydrocephalus. Surgery, such as foramen magnum decompression, is indicated for a symptomatic Chiari malformation, although an incidental lesion may be followed-up without further treatment. Infrequently, increased intracranial pressure emerges due to hyperthyroidism. A nineteen-year-old girl visited our outpatient clinic presented with a headache, nausea and vomiting. A brain and spinal magnetic resonance image study (MRI) indicated that the patient had a Chiari I malformation without syringomyelia or hydrocephalus. An enlarged thyroid gland was detected on a physical examination, and serum markers indicated Graves' disease. The patient started anti-hyperthyroid medical treatment. Subsequently, the headache disappeared after the medical treatment of hyperthyroidism without surgical intervention for the Chiari malformation. A symptomatic Chiari malformation is indicated for surgery, but a surgeon should investigate other potential causes of the symptoms of the Chiari malformation to avoid unnecessary surgery.

    Performance during object recognition across views is largely dependent on inter-object similarity. The present study was designed to investigate the similarity dependency of object recognition learning on the changes in ERP component N1. Human subjects were asked to train themselves to recognize novel objects with different inter-object similarity by performing object recognition tasks. During the tasks, images of an object had to be discriminated from the images of other objects irrespective of the viewpoint. When objects had a high inter-object similarity, the ERP component, N1 exhibited a significant increase in both the amplitude and the latency variation across objects during the object recognition learning process, and the N1 amplitude and latency variation across the views of the same objects decreased significantly. In contrast, no significant changes were found during the learning process when using objects with low inter-object similarity. The present findings demonstrate that the changes in the variation of N1 that accompany the object recognition learning process are dependent upon the inter-object similarity and imply that there is a difference in the neuronal representation for object recognition when using objects with high and low inter-object similarity.

    Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to deficiency of sex steroid hormone. Graves' disease is also an important cause of secondary osteoporosis. However, IHH does not preclude the development of primary hyperthyroidism caused by Graves' disease, leading to more severe osteoporosis rapidly. Here, we describe the first case of 35-year-old Asian female patient with IHH accompanied by Graves' disease and osteoporosis-induced multiple fractures. Endocrine laboratory findings revealed preserved anterior pituitary functions except for secretion of gonadotropins and showed primary hyperthyroidism with positive autoantibodies. Sella magnetic resonance imaging showed slightly small sized pituitary gland without mass lesion. Dual energy X-ray absorptiometry revealed severe osteoporosis in lumbar spine and femur neck of the patient. Plain film radiography of the pelvis and shoulder revealed a displaced and nondisplaced fracture, respectively. After surgical fixation with screws for the femoral fracture, the patient was treated with antithyroid medication, calcium, and vitamin D until now and has been recovering fairly well. We report a patient of IHH with Graves' disease and multiple fractures that is a first case in Korea. PMID:26981520

    We investigate continuous-time quantum walks of two fermionic atoms loaded in one-dimensional optical lattices with on-site interaction and subjected to a Zeeman field. The quantum walks are accompanied by spin-flipping processes. We calculate the time-dependent density distributions of the two fermions with opposite spins which are initially positioned at the center site by means of an exact numerical method. Besides the usual fast linear expansion behavior, we find an interesting spin-flipping-induced localization in the time evolution of density distributions. We show that the fast linear expansion behavior can be restored by simply ramping up the Zeeman field or further increasing the spin-flipping strength. The intrinsic origin of this exotic phenomenon is attributed to the emergence of a flat band in the single-particle spectrum of the system. Furthermore, we investigate the effect of on-site interaction on the dynamics of the quantum walkers. The two-particle correlations are calculated and the signal of localization is also shown therein. A simple potential experimental application of this interesting phenomenon is proposed.

    The Swift-discovered GRB 080319B was by far the most distant source ever observed at naked-eye brightness, reaching a peak apparent magnitude of 5.3 at a redshift of z = 0.937. We present our late-time optical (Hubble Space Telescope, Gemini, and Very Large Telescope) and X-ray (Chandra) observations, which confirm that an achromatic break occurred in the power-law afterglow light curve at ~11 days post-burst. This most likely indicates that the gamma-ray burst (GRB) outflow was collimated, which for a uniform jet would imply a total energy in the jet E jet >~ 1052 erg. Our observations also show a late-time excess of red light, which is well explained if the GRB was accompanied by a supernova (SN), similar to those seen in some other long-duration GRBs. The latest observations are dominated by light from the host and show that the GRB took place in a faint dwarf galaxy (r(AB) ≈ 27.0, rest frame MB ≈ -17.2). This galaxy is small even by the standards of other GRB hosts, which is suggestive of a low-metallicity environment. Intriguingly, the properties of this extreme event—a small host and bright SN—are entirely typical of the very low luminosity bursts such as GRB 980425 and GRB 060218.

    Temperature-jump-induced absorbance changes of spinach chloroplasts in the dark were studied. After the temperature rise, a fast absorbance decrease and a succeeding slow absorbance increase were observed at the wavelength of 515 nm. The spectrum of the fast phase had positive maxima (increase in absorbance) at 430, 470 and 673 nm and a negative maxima (decrease in absorbance) at 525 nm. Permeant ions, tetraphenylboron-, tetraphenylarsonium+, and tetraphenylphosphonium+, decreased the extent of the fast absorbance change and increased the rate of slow recovery. Additions of inorganic potassium salts had a similar effect. Valinomycin, added in the presence of potassium ion, also increased the rate of slow recovery. These ions and ionophore had a parallel effect also on the recovery of flash-induced 515-nm absorbance change in chloroplasts. Electroneutral nigerericin did not affect the temperature-jump-induced absorbanc change. These results suggest the formation of electrical field across the thylakoid membrane in the dark accompanying the temperature rise. A possible involvement of the movement of water molecules (thermo-osmosis) in the observed absorbance changes is also discussed. PMID:849433

    We aim to test the feasibility of using near-infrared spectroscopy (NIRS) for indirect measurement of human saliva secretion in response to taste stimuli for potential application to organoleptic testing. We use an NIRS system to measure extracranial hemodynamics (Hb-signals around the temples) of healthy participants when taste stimuli are taken in their mouths. First, the Hb-signals and volume of expelled saliva (stimulated by distilled-water or sucrose-solution intake) are simultaneously measured and large Hb-signal changes in response to the taste stimuli (Hb-responses) are found. Statistical analysis show that both the Hb response and saliva volume are larger for the sucrose solution than for the distilled water with a significant correlation between them (r = 0.81). The effects of swallowing on the Hb-signals are investigated. Similar Hb responses, differing from the sucrose solution and distilled water, are obtained even though the participants swallow the mouth contents. Finally, functional magnetic resonance imaging is used to identify possible sources of the Hb signals corresponding to salivation. Statistical analysis indicates similar responses in the extracranial regions, mainly around the middle meningeal artery. In conclusion, the identified correlation between extracranial hemodynamics and the saliva volume suggests that NIRS is applicable to the measurement of hemodynamic signals accompanying stimulated saliva secretion.

    Introduction Cytomegalovirus (CMV) infection of the gastrointestinal tract is an uncommon illness, but can be observed in immunocompromised patients. Systemic lupus erythematosus (SLE) patients are generally at high risk of CMV infection. Here we report a subacute progressive case of colitis in SLE accompanied by cytomegalovirus infection. Presentation of case The patient, a 79-year-old woman, was hospitalized complaining of fever, polyarthritis, and skin ulcer that had lasted seven days. She additionally manifested vomiting, high fever, and right abdominal pain within two weeks thereafter, and was diagnosed with perforation of the intestine. Emergency operation was carried out for panperitonitis due to perforation of one of the multiple colon ulcers. Multidisciplinary postoperative treatment could not save her life. Pathological examination suggested that cytomegalovirus infection as well as cholesterin embolization contributed to the rapid progression of colitis. Discussion There have been only a limited number of case reports of CMV enteritis in SLE. Moreover, only two SLE patients on multiple medications have been reported to experience gastrointestinal perforation. Viral infections, including CMV, can induce clinical manifestations resembling SLE and for this reason we suspect that there are potentially many more patients misdiagnosed and/or unreported. Conclusion Our case underscores the importance of exploring the possibility of CMV infection as a differential diagnosis in SLE patients with obvious gastrointestinal symptoms who were treated by immunosuppressive drugs.

  16. Two sources of meaning in infant communication: preceding action contexts and act-accompanying characteristics

    How do infants communicate before they have acquired a language? This paper supports the hypothesis that infants possess social–cognitive skills that run deeper than language alone, enabling them to understand others and make themselves understood. I suggested that infants, like adults, use two sources of extralinguistic information to communicate meaningfully and react to and express communicative intentions appropriately. In support, a review of relevant experiments demonstrates, first, that infants use information from preceding shared activities to tailor their comprehension and production of communication. Second, a series of novel findings from our laboratory shows that in the absence of distinguishing information from preceding routines or activities, infants use accompanying characteristics (such as prosody and posture) that mark communicative intentions to extract and transmit meaning. Findings reveal that before infants begin to speak they communicate in meaningful ways by binding preceding and simultaneous multisensory information to a communicative act. These skills are not only a precursor to language, but also an outcome of social–cognitive development and social experience in the first year of life. PMID:25092662

    The absorption of nitric oxide (NO) into aqueous solutions of ferrous chelates of nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), hydroxyethylenediaminetriacetic acid (HEDTA), and diethylenetriaminepentaacetic acid (DTPA) was studied in a stirred cell reactor. The absorption leads to stable ferrous NO chelates. Due to the high reaction rate, in combination with the relatively high P{sub NO} applied, the absorption rate is strongly affected by mass transfer limitation only. By applying penetration theory, the ratio of the diffusion coefficients of ferrous chelates and NO was determined. At elevated T, (D{sub Fe(II)chelate}/D{sub NO}){sup 1/2} decreases due to the unusual T-dependency of D{sub NO}. For ferrous NTA, the formation of the ferrous NO chelate is accompanied by pH effects that can be understood from iron chelate chemistry. In the case of ferrous NTA, pH < 5, or an excess of ligand, these effects lead to local pH gradients at the gas-liquid interface, that substantially affect the NO absorption rates. Kinetic data from the literature on the absorption of NO into ferrous chelates were evaluated using the mass transfer parameters determined. These kinetic data are often unreliable.

    High levels of impulsivity have been linked to a number of psychiatric disorders, including attention-deficit/hyperactivity disorder, drug abuse and schizophrenia. Additionally, schizophrenia patients commonly show deficits in another rather preattentive form of response inhibition, called sensorimotor gating. Given that higher-order functions, such as impulse control, are protected by early and preattentive processes, disturbed gating mechanisms may hamper more complex cognitive-executive functions. In the present study, we therefore tested whether high levels of impulsivity are accompanied by impaired sensorimotor gating in rats. High (HI) and low impulsive (LI) rats were identified based on the number of premature responses in the 5-choice serial reaction time task. Here, LI rats showed higher numbers of omission errors which may suggest attentional deficits while HI rats completed significantly less trials which could indicate a decrease in motivation. However, HI and LI rats did not differ in terms of impulsive decision-making in a delay-based decision-making T-maze task, prepulse inhibition of the acoustic startle response (a measure of sensorimotor gating mechanisms) or locomotor activity levels. Overall, our data indicate that high motor impulsivity is not a suitable predictor of deficient sensorimotor gating and is further not necessarily associated with attentional deficits and/or locomotor hyperactivity in rats.

    Molecules that extend and contract under external stimuli are used to build molecular machines with nanomechanical functions. But although common in biological systems, such extension and contraction motions with helical molecules have rarely been accompanied by unidirectional twisting in synthetic systems. Here we show that sodium ions can trigger the reversible anisotropic twisting of an enantiomeric double-stranded helicate, without racemization. An optically active helicate consisting of two tetraphenol strands bridged by two spiroborate groups sandwiches a sodium ion. On removal of the central sodium-through addition of a cryptand [2.2.1] in solution-the double helicate extends. Crystallographic and nuclear magnetic resonance studies reveal that the extended helicate is over twice as long as the initial molecule, and is twisted in the right-handed direction. Circular dichroism analysis suggests that the twisting doesn't affect the helicate's handedness. This anisotropic extension-contraction process is reversibly triggered by the successive addition and removal of sodium ions in solution. PMID:20489711

    In everyday conversation, listeners often rely on a speaker’s gestures to clarify any ambiguities in the verbal message. Using fMRI during naturalistic story comprehension, we examined which brain regions in the listener are sensitive to speakers’ iconic gestures. We focused on iconic gestures that contribute information not found in the speaker’s talk, compared to those that convey information redundant with the speaker’s talk. We found that three regions—left inferior frontal gyrus triangular (IFGTr) and opercular (IFGOp) portions, and left posterior middle temporal gyrus (MTGp)—responded more strongly when gestures added information to non-specific language, compared to when they conveyed the same information in more specific language; in other words, when gesture disambiguated speech as opposed to reinforced it. An increased BOLD response was not found in these regions when the non-specific language was produced without gesture, suggesting that IFGTr, IFGOp, and MTGp are involved in integrating semantic information across gesture and speech. In addition, we found that activity in the posterior superior temporal sulcus (STSp), previously thought to be involved in gesture-speech integration, was not sensitive to the gesture-speech relation. Together, these findings clarify the neurobiology of gesture-speech integration and contribute to an emerging picture of how listeners glean meaning from gestures that accompany speech.

  2. Bias in GRACE estimates of ice mass change due to accompanying sea-level change

    Observations of spatio-temporal variations in the geopotential using the GRACE satellites have been used to estimate recent mass fluxes from polar ice sheets and glaciers. However, these estimates have not considered the potential bias associated with the migration of water that accompanies the ice melt. This migration is driven by the diminished gravitational attraction of the melting ice reservoir, and this migration, as well as the crustal loading it induces, will contribute to the observed geopotential anomaly. The extent to which this contribution contaminates the ice mass flux estimates depends on how far the smoothing filters applied to the GRACE data extend beyond the ice margins into the ocean. Using the Antarctic Peninsula as a case study, we estimate the magnitude of this bias for a range of melt areas and Gaussian smoothing filter radii. We conclude that GRACE estimates of ice mass loss over the Antarctic Peninsula are systematically overestimating the loss by up to 10 % for filter radii of less than 500 km.

    In several preclinical tumor models, antitumor effects occur after intratumoral electroporation, also known as electrotransfer, of plasmid DNA devoid of a therapeutic gene. In mouse melanomas, these effects are preceded by significant elevation of several proinflammatory cytokines. These observations implicate the binding and activation of intracellular DNA-specific pattern recognition receptors or DNA sensors in response to DNA electrotransfer. In tumors, IFNβ mRNA and protein levels significantly increased. The mRNAs of several DNA sensors were detected, and DAI, DDX60, and p204 tended to be upregulated. These effects were accompanied with reduced tumor growth and increased tumor necrosis. In B16.F10 cells in culture, IFNβ mRNA and protein levels were significantly upregulated. The mRNAs for several DNA sensors were present in these cells; DNA-dependent activator of interferon regulatory factor (DAI), DEAD (Asp-Glu-Ala-Asp) box polypeptide 60 (DDX60), and p204 were significantly upregulated while DDX60 protein levels were coordinately upregulated. Upregulation of DNA sensors in tumors could be masked by the lower transfection efficiency compared to in vitro or to dilution by other tumor cell types. Mirroring the observation of tumor necrosis, cells underwent a significant DNA concentration-dependent decrease in proliferation and survival. Taken together, these results indicate that DNA electrotransfer may cause the upregulation of several intracellular DNA sensors in B16.F10 cells, inducing effects in vitro and potentially in vivo.

    The evolution of predominant self-fertilization from cross-fertilization in plants is accompanied by diverse changes to morphology, ecology and genetics, some of which likely result from regulatory changes in gene expression. We examined changes in gene expression during early stages in the transition to selfing in populations of animal-pollinated Eichhornia paniculata with contrasting mating patterns. We crossed plants from outcrossing and selfing populations and tested for the presence of allele-specific expression (ASE) in floral buds and leaf tissue of F1 offspring, indicative of cis-regulatory changes. We identified 1365 genes exhibiting ASE in floral buds and leaf tissue. These genes preferentially expressed alleles from outcrossing parents. Moreover, we found evidence that genes exhibiting ASE had a greater nonsynonymous diversity compared to synonymous diversity in the selfing parents. Our results suggest that the transition from outcrossing to high rates of self-fertilization may have the potential to shape the cis-regulatory genomic landscape of angiosperm species, but that the changes in ASE may be moderate, particularly during the early stages of this transition.

    The protein mixture of cytokine-inducing activity accompanying chicken immunoglobulin Y, named yolkin, consists of several peptides of molecular weight (MW) ranging from over 1 to 35 kDa. Yolkin and its constituent peptides were found to be efficient inducers of interleukin (IL)-1β, IL-6 and IL-10 secretion. N-terminal amino acid sequences of eight of the electrophoretically purified yolkin constituents revealed that all of them are homological to some fragments of the C-terminal domain of vitellogenin II. The fractions of MW about 4 and 12 kDa are free of carbohydrates and start at position 1732 in the vitellogenin amino acid sequence; whereas the other fractions (MW about 16, 19, 23, 29, 32 and 35 kDa) appeared to be glycoproteins corresponding to the amino acid sequence of vitellogenin starting at position 1572. From these data, it is concluded that yolkin most likely represents vitellogenin-derived peptides that possess cytokine-inducing activity and are, at least partially, responsible for such properties of separated immunoglobulin Y preparation. This finding reveals a new role for vitellogenin as a reservoir of polypeptides that may play an important role in the innate immune system of the developing embryo. PMID:23492558

    We describe the case of a patient with sigmoid colon cancer liver metastasis accompanied by multiple liver abscesses. The 59-year-old female patient presented with a fever at a body temperature of 39.0°C. On abdominal computed tomography (CT), multiple liver abscesses were detected, and percutaneous transhepatic abscess drainage (PTAD) was performed. The day after the PTAD, the patient's fever subsided and her inflammatory response abated. A lower gastrointestinal examination, performed to identify the origin of her symptoms, revealed a type 1 tumor in the sigmoid colon. A biopsy indicated a moderately differentiated adenocarcinoma. Prior to surgery, a second abdominal CT scan was performed, and a single liver metastasis was detected. Laparoscopic sigmoidectomy and partial liver resection were simultaneously performed. The histopathological diagnosis of the colon cancer was tub2, pN1, pH1, P0, ly1, v1, stage IV. To date, the patient remains free from hepatic abscess and colon cancer recurrence. Gastrointestinal examinations should be performed as early as possible to identify the cause of hepatic abscesses. Moreover, therapeutic decisions should only be made after imaging and examinations have been performed, which will be sufficient to identify the presence of liver metastases. PMID:25731285

    Photosynthetic organisms have various pigments enabling them to adapt to various light environments. Green plants are divided into two groups: streptophytes and chlorophytes. Streptophytes include some freshwater green algae and land plants, while chlorophytes comprise the other freshwater green algae and seawater green algae. The environmental conditions driving the divergence of green plants into these two groups and the changes in photosynthetic properties accompanying their evolution remain unknown. Here, we separated the core antennae of PSI and the peripheral antennae [light-harvesting complexes (LHCs)] in green plants by green-native gel electrophoresis and determined their pigment compositions. Freshwater green algae and land plants have high Chl a/b ratios, with most Chl b existing in LHCs. In contrast, seawater green algae have low Chl a/b ratios. In addition, Chl b exists not only in LHCs but also in PSI core antennae in these organisms, a situation beneficial for survival in deep seawater, where blue-green light is the dominant light source. Finally, low-energy Chl (red Chl) of PSI was detected in freshwater green algae and land plants, but not in seawater green algae. We thus conclude that the different level of Chl b accumulation in core antennae and differences in PSI red Chl between freshwater and seawater green algae are evolutionary adaptations of these algae to their habitats, especially to high- or low-light environments.

    Pea (Pisum sativum) cell wall metabolism in response to chilling was investigated in a frost-sensitive genotype 'Terese' and a frost-tolerant genotype 'Champagne'. Cell walls isolated from stipules of cold acclimated and non-acclimated plants showed that cold temperatures induce changes in polymers containing xylose, arabinose, galactose and galacturonic acid residues. In the tolerant cultivar Champagne, acclimation is accompanied by increases in homogalacturonan, xylogalacturonan and highly branched Rhamnogalacturonan I with branched and unbranched (1→5)-α-arabinans and (1→4)-β-galactans. In contrast, the sensitive cultivar Terese accumulates substantial amounts of (1→4)-β-xylans and glucuronoxylan, but not the pectins. Greater JIM7 labeling was observed in Champagne compared to Terese, indicating that cold acclimation also induces an increase in the degree of methylesterification of pectins. Significant decrease in polygalacturonase activities in both genotypes were observed at the end of cold acclimation. These data indicate a role for esterified pectins in cold tolerance. The possible functions for pectins and their associated arabinans and galactans in cold acclimation are discussed. PMID:24837358

    The sirtuin family consists of seven NAD+-dependent enzymes affecting a broad array of regulatory protein networks by primarily catalyzing the deacetylation of key lysine residues in regulatory proteins. The enzymatic activity of SIRT1 can be enhanced by small molecule activators known as SIRT1 activator compounds (STACs). We tested the therapeutic potential of the STAC SRT3025 in two preclinical models of severe infection, the murine cecal ligation and puncture (CLP) model to induce peritonitis and intratracheal installation of Streptococcus pneumoniae to induce severe bacterial pneumonia. SRT3025 provided significant survival benefits over vehicle control in both the peritonitis and pneumococcal pneumonia models when administered with appropriate antimicrobial agents. The survival benefit of SRT3025 in the CLP model was absent in SIRT1 knockout showing the SIRT1 dependency of SRT3025's effects. SRT3025 administration promoted bacterial clearance and significantly reduced inflammatory cytokines from the lungs of animals challenged with S. pneumoniae. SRT3025 treatment was also accompanied by striking changes in the transcription profiles in multiple inflammatory and metabolic pathways in liver, spleen, small bowel, and lung tissue. Remarkably, these organ-specific changes in the transcriptome analyses were similar following CLP or pneumococcal challenge despite different sets of pathogens at disparate sites of infection. Pharmacologic activation of SIRT1 modulates the innate host response and could represent a novel treatment strategy for severe infection. PMID:26974318

    An algorithm of the accompanying coordinate expansion and recurrence relation (ACE-RR), which is used for the rapid evaluation of the electron repulsion integral (ERI), has been extended to the general-contraction (GC) scheme. The present algorithm, denoted by GC-ACE-RR, is designed for molecular calculations including heavy elements, whose orbitals consist of many primitive functions with and without higher angular momentum such as d- and f-orbitals. The performance of GC-ACE-RR was assessed for (ss|ss)-, (pp|pp)-, (dd|dd)-, and (ff|ff)-type ERIs in terms of contraction length and the number of GC orbitals. The present algorithm was found to reduce the central processing unit time compared with the ACE-RR algorithm, especially for higher angular momentum and highly contracted orbitals. Compared with HONDOPLUS and GAMESS program packages, GC-ACE-RR computations for ERIs of three-dimensional gold clusters Aun (n = 1, 2, …, 10, 15, 20, and 25) are more than 10 times faster.

    Scleractinian corals are assumed to be stenohaline osmoconformers, although they are frequently subjected to variations in seawater salinity due to precipitation, freshwater run-off and other processes. Observed responses to altered salinity levels include differences in photosynthetic performance, respiration and increased bleaching and mortality of the coral host and its algal symbiont, but a study looking at bacterial community changes is lacking. Here, we exposed the coral Fungia granulosa to strongly increased salinity levels in short- and long-term experiments to disentangle temporal and compartment effects of the coral holobiont (i.e. coral host, symbiotic algae and associated bacteria). Our results show a significant reduction in calcification and photosynthesis, but a stable microbiome after short-term exposure to high-salinity levels. By comparison, long-term exposure yielded unchanged photosynthesis levels and visually healthy coral colonies indicating long-term acclimation to high-salinity levels that were accompanied by a major coral microbiome restructuring. Importantly, a bacterium in the family Rhodobacteraceae was succeeded by Pseudomonas veronii as the numerically most abundant taxon. Further, taxonomy-based functional profiling indicates a shift in the bacterial community towards increased osmolyte production, sulphur oxidation and nitrogen fixation. Our study highlights that bacterial community composition in corals can change within days to weeks under altered environmental conditions, where shifts in the microbiome may enable adjustment of the coral to a more advantageous holobiont composition.

    Nanoparticles, such as gold nanoparticles (GNP), upon convenient modifications perform multi tasks catering to many biomedical applications. However, GNP or any other type of nanoparticles is yet to achieve the feat of intracellular regulation of endogenous genes of choice such as through manipulation of a gene-promoter in a chromosome. As for gene modulation and delivery, GNP (or other nanoparticles) showed only limited gene therapy potential, which relied on the delivery of `exogenous' genes invoking gene knockdown or replacement. Practically, there are no instances for the nanoparticle-mediated promoter regulation of `endogenous' genes, more so, as a cancer selective phenomenon. In this regard, we report the development of a simple, easily modifiable GNP-formulation, which promoted/up-regulated the expression of a specific category of `endogenous' genes, the glucocorticoid responsive genes. This genetic up-regulation was induced in only cancer cells by modified GNP-mediated transcriptional activation of its cytoplasmic receptor, glucocorticoid receptor (GR). Normal cells and their GR remained primarily unperturbed by this GNP-formulation. The most potent gene up-regulating GNP-formulation down-regulated a cancer-specific proliferative signal, phospho-Akt in cancer cells, which accompanied retardation of tumor growth in the murine melanoma model. We show that GR-targeted GNPs may find potential use in the targeting and modulation of genetic information in cancer towards developing novel anticancer therapeutics.Nanoparticles, such as gold nanoparticles (GNP), upon convenient modifications perform multi tasks catering to many biomedical applications.

  13. Processes accompanying of mantle plume emplacement into continental lithosphere: Evidence from NW Arabian plate, Western Syria

    Lower crustal xenoliths occurred in the Middle Cretaceous lamprophyre diatremes in Jabel Ansaria (Western Syria) (Sharkov et al., 1992). They are represented mainly garnet granulites and eclogite-like rocks, which underwent by deformations and retrograde metamorphism, and younger fresh pegmatoid garnet-kaersutite-clinopyroxene (Al-Ti augite) rocks; mantle peridotites are absent in these populations. According to mineralogical geothermobarometers, forming of garnet-granulite suite rocks occurred under pressure 13.5-15.4 kbar (depths 45-54 kn) and temperature 965-1115oC. At the same time, among populations of mantle xenoliths in the Late Cenozoic platobasalts of the region, quite the contrary, lower crustal xenoliths are absent, however, predominated spinel lherzolites (fragments of upper cooled rim of a plume head), derived from the close depths (30-40 km: Sharkov, Bogatikov, 2015). From this follows that ancient continental crust was existed here even in the Middle Cretaceous, but in the Late Cenozoic was removed by extended mantle plume head; at that upper sialic crust was not involved in geomechanic processes, because Precambrian metamorphic rocks survived as a basement for Cambrian to Cenozoic sedimentary cover of Arabian platform. In other words, though cardinal rebuilding of deep-seated structure of the region occurred in the Late Cenozoic but it did not affect on the upper shell of the ancient lithosphere. Because composition of mantle xenolithis in basalts is practically similar worldwide, we suggest that deep-seated processes are analogous also. As emplacement of the mantle plume heads accompanied by powerful basaltic magmatism, very likely that range of lower (mafic) continental crust existence is very convenient for extension of plume heads and their adiabatic melting. If such level, because of whatever reasons, was not reached, melting was limited but appeared excess of volatile matters which led to forming of lamprophyre or even kimberlite.

    Although stress-induced hyperlipidemia and increased oxidative stress have been reported and implicated in etiology of atherosclerosis, experimental evidence for stress-induced atherosclerotic development concomitant with these alterations is lacking. In this study, exposure of adult male albino Wistar rats (Rattus norvegicus) to restraint for 1 h and after a gap of 4 h to forced swimming for 15 min every day for 2, 4, or 24 weeks resulted in a duration of exposure-dependent hyperlipidemia as shown by significant increases in concentrations of blood cholesterol, low-density lipoproteins, and triglycerides and decrease in high-density lipoprotein concomitant with increased oxidative stress as indicated by decrease in hepatic antioxidant enzyme activities and increase in lipid peroxidation in the liver, kidney, and heart. These alterations were accompanied by development of fibrous layer, formation of foam cells, reduction in elastic fibers, and accumulation of Oil-Red-O-positive lipid droplets in the intima of thoracic aorta following 24 weeks of stress exposure, but not after 4 weeks. The study demonstrates for the first time that (i) chronic stress-induced hyperlipidemia and oxidative damage are coupled with atherosclerotic development in rats fed with normal diet and (ii) chronic stress effects prevail even after the cessation of stress exposure as indicated by high concentration of blood cholesterol and reduced hepatic superoxide dismutase activity 20 weeks after 2 or 4 weeks of stress. This study exemplifies long-term allostatic regulation leading to a pathological state, with long-term hyperlipidemia and oxidative damage from chronic stress resulting in atherosclerosis.

    Chondrules probably formed by melting and subsequent cooling of solid precursors. Evaporation during chondrule melting may have resulted in depletion of volatile elements in chondrules. It is known that kinetic evaporation, especially evaporation from a melt, often leads to enrichment of heavy isotopes in an evaporation residue. However, no evidence for a large degree of heavy-isotope enrichment has been reported in chondrules for K, Mg, Si, and Fe (as FeO). The lack of isotopic fractionation has also been found for sulfur in troilites (FeS) within Bishunpur (LL3.1) and Semarkona (LL3.0) chondrules by an ion microprobe study. The largest fractionation, found in only one grain, was 2.7 +/- 1.4 %/amu, while all other troilite grains showed isotopic fractionations of <1 %/amu. The suppressed isotopic fractionation has been interpreted as results of (i) rapid heating of precursors at temperatures below the silicate solidus and (ii) diffusion-controlled evaporation through a surrounding silicate melt at temperatures above the silicate solidus. The kinetic evaporation model suggests that a rapid heating rate of >10(exp 4)-10(exp 6) K/h for a temperature range of 1000-1300 C is required to explain observed isotopic fractionations. Such a rapid heating rate seems to be difficult to be achieved in the X-wind model, but can be achieved in shock wave heating models. In this study, we have applied the sulfur evaporation model to the shock wave heating conditions of to evaluate evaporation of sulfur and accompanying isotopic fractionation during shock wave heating at temperatures below the silicate solidus.

    Aggression, costly in both time and energy, is often expressed by male animals in defense of valuable resources such as food or potential mates. Here we present a new insect model system for the study of aggression, the male flesh fly Sarcophaga crassipalpis, and ask whether there is an ontogeny of aggression that coincides with reproductive maturity. After establishing that reproductive maturity occurs by day 3 of age (post-eclosion), we examined the behavior of socially isolated males from different age cohorts (days 1, 2, 3, 4, and 6) upon introduction, in a test arena, with another male of the same age. The results show a pronounced development of aggression with age. The change from relative indifference to heightened aggression involves a profound increase in the frequency of high-intensity aggressive behaviors between days 1 and 3. Also noteworthy is an abrupt increase in the number of statistically significant transitions involving these full-contact agonistic behaviors on day 2. This elevated activity is trimmed back somewhat by day 3 and appears to maintain a stable plateau thereafter. No convincing evidence was found for escalation of aggression nor the establishment of a dominance relationship over the duration of the encounters. Despite the fact that aggressive interactions are brief, lasting only a few seconds, a major reorganization in the relative proportions of four major non-aggressive behaviors (accounting for at least 96% of the total observation time for each age cohort) accompanies the switch from low to high aggression. A series of control experiments, with single flies in the test arenas, indicates that these changes occur in the absence of the performance of aggressive behaviors. This parallel ontogeny of aggressive and non-aggressive behaviors has implications for understanding how the entire behavioral repertoire may be organized and reorganized to accommodate the needs of the organism.

    Various hepato-biliary complications are an increased incidence in patients with inflammatory bowel disease, and portal bacteremia is well documented in patients with ulcerative colitis (UC). However, few reports mention UC in association with liver abscesses. Recently, there are several reports describing cytomegalovirus (CMV) infection in association with disease exacerbation and steroid refractoriness in patients with UC. Here we present a case of refractory UC accompanied with multiple liver abscesses and CMV colitis. The patient, a 72-year-old male, with a five-year history of repeated admissions to our hospital for UC, presented with an exacerbation of his UC. Sigmoidoscopy performed on admission suggested that his UC was exacerbated, then he was given prednisolone and mesalazine orally, and betamethasone enemas. However, he had exacerbated symptoms. Repeat sigmoidoscopy revealed multiple longitudinal ulcers and pseudopolyps in the rectosigmoid colon. Although immunohistochemical staining of biopsy specimens and the serum testing for antigenemia were negative on admission and after the repeat sigmoidoscopy, they became histologically positive for CMV. Nonetheless, the patient developed spiking fevers, soon after ganciclovir was administered. Laboratory studies revealed an increased white cell count with left shift, and Enterococcus fecalis grew in blood cultures. An abdominal computed tomography (CT) scan was obtained and the diagnosis of liver abscesses associated with UC was made, based on CT results. The hepatic abscesses were successfully treated with intravenous meropenem for 6 wk, without further percutaneous drainage. To our knowledge, this is the first reported case of multiple liver abscesses that develop during UC exacerbation complicated by CMV colitis. PMID:16127763

  18. REM and NREM sleep as natural accompaniments of the evolution of warm-bloodedness.

    Divergence of primitive sleep into REM and NREM states is thought to have occurred in the nocturnal Triassic ancestors of mammals as a natural accompaniment of the evolution of warm-bloodedness. As ambient temperatures during twilight portions of primitive sleep traversed these evolving ancestors' core temperature, mechanisms of thermoregulatory control that employ muscle contractions became superfluous. The resulting loss of need for such contractions during twilight sleep led to muscle atonia. With muscle tone absent, selection favored the persistence of the fast waves of nocturnal activity during twilight sleep. Stimulations by these waves reinforce motor circuits at the increasing temperatures of evolving warm-bloodedness without leading to sleep-disturbing muscle contractions. By these and related interlinked adaptations, twilight sleep evolved into REM sleep. The daytime period of sleep became NREM sleep. The evolution of NREM and REM sleep following this scenario has implications for sleep's maintenance processes for long-term memories. During NREM sleep, there is an unsynchronized, uncoordinated stimulation and reinforcement of individual distributed component circuits of consolidated memories by slow wave potentials, a process termed 'uncoordinated reinforcement'. The corresponding process during REM sleep is the coordinated stimulation and reinforcement of these circuits by fast wave potentials. This action temporally binds the individual component circuit outputs into fully formed memories, a process termed 'coordinated reinforcement'. Sequential uncoordinated and coordinated reinforcement, that is, NREM followed by REM sleep, emerges as the most effective mechanism of long-term memory maintenance in vertebrates. With the evolution of this two-stage mechanism of long-term memory maintenance, it became adaptive to partition sleep into several NREM-REM cycles, thereby achieving a more lengthy application of the cooperative sequential actions.

  19. Theory of the jitter radiation in a magnetized plasma accompanying a temperature gradient

    2016-04-01

    The linear stability of a magnetized plasma accompanying a temperature gradient is reexamined by using plasma kinetic theory. We propose that the anisotropic velocity distribution function should be decomposed into two components. One is proportional to the temperature gradient parallel to the background magnetic field. The other is proportional to the temperature gradient perpendicular to the background magnetic field. Since the amplitude of the anisotropic velocity distribution function is proportional to the heat conductivity, and the heat conductivity perpendicular to the magnetic field is strongly reduced, the first component of the anisotropic velocity distribution function is predominant. The anisotropic velocity distribution function induced by the temperature gradient along the background magnetic field drives plasma kinetic instability and circular polarized magnetic plasma waves are excited. We show that the instability is almost identical to the Weibel instability in the weakly magnetized plasma. However, in the case of the instability caused by the temperature gradient, whether wave vectors of modes are parallel to or antiparallel to the background magnetic field, the growth rate of one mode is suppressed and the growth rate of the other mode is enhanced due to the background magnetic field. In the strongly magnetized plasma, one mode is stabilized and only one of the modes remains unstable. The formulae for the jitter radiation spectrum emitted by relativistic electrons when they travel through the magnetized plasma with the plasma waves driven by the instability are deduced at the first time. We show that the synchrotron emission and the jitter radiation are simultaneously emitted from the same relativistic electron. The jitter radiation is expected to be circularly polarized but with a very small polarization degree since almost the same amounts of left-handed and right-handed circular polarized magnetic waves are excited by the instability.

    Purpose. To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. Methods. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb) and deoxyhemoglobin (DeoxyHb) levels were detected before and after treatment after 15, 30, and 45 days. Results. In this cohort, pretreatment OxyHb (mean ± SD) is 1.32 ± 0.14 (medium-high), and DeoxyHb is 0.87 ± 0.13 (normal). All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23 ± 0.09 (normal-medium, 15-day), 1.16 ± 0.08 (normal, 30-day), and 1.05 ± 0.04 (normal, 45-day), and DeoxyHb levels are 0.90 ± 0.11 (normal, 15-day), 0.94 ± 0.18 (normal, 30-day), and 0.98 ± 0.12 (normal, 45-day). Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Conclusion. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

    Förster resonance energy transfer (FRET) is a highly efficient strategy in illuminating the structures, structural changes and dynamics of DNA, proteins and other biomolecules and thus is being widely utilized in studying such phenomena, in designing molecular/biomolecular probes for monitoring the hybridization event of two single stranded DNA to form duplex, in gene detection and in many other sensory applications in chemistry, biology and material sciences. Moreover, FRET can give information about the positional status of chromophores within the associated biomolecules with much more accuracy than other methods can yield. Toward this end, we want to report here the ability of fluorescent unnatural nucleoside, triazolylphenanthrene ((TPhen)BDo) to show FRET interaction upon hybridization with fluorescently labeled natural nucleosides, (Per)U or (OxoPy)U or (Per)U, forming two stable chimeric DNA duplexes. The pairing selectivity and the thermal duplex stability of the chimeric duplexes are higher than any of the duplexes with natural nucleoside formed. The hybridization results in a Förster resonance energy transfer (FRET) from donor triazolylphenanthrene of (TPhen)BDo to acceptor oxopyrene of (OxoPy)U and/or to perylene chromophore of (Per)U, respectively, in two chimeric DNA duplexes. Therefore, we have established the FRET process in two chimeric DNA duplexes wherein a fluorescently labeled natural nucleoside ((OxoPy)U or (Per)U) paired against an unnatural nucleoside ((TPhen)BDo) without sacrificing the duplex stability and B-DNA conformation. The hybridization accompanying FRET event in these classes of interacting fluorophores is new. Moreover, there is no report of such designed system of chimeric DNA duplex. Our observed phenomenon and the design can potentially be exploited in designing more of such efficient FRET pairs for useful application in the detection and analysis of biomolecular interactions and in material science application.

    Purpose To investigate the changes in choroidal thickness (CT), axial length (AL), and ocular perfusion pressure (OPP) accompanying intraocular pressure (IOP) reduction after trabeculectomy. Methods Thirty-nine eyes of 39 patients with primary open-angle glaucoma uncontrolled by medical therapy were included in this prospective and interventional study. All patients underwent a fornix-based trabeculectomy. The CT was measured by enhanced depth imaging-optical coherence tomography. IOP, AL, and systolic/diastolic blood pressure were also measured, and OPP was calculated. All measurements were performed at baseline and 1 month after surgery. Results The mean IOP was 25.0±5.8 mm Hg at baseline and 11.7±2.6 mm Hg after trabeculectomy (P<0.001), and the mean subfoveal CT was 295±84 mm Hg at baseline and 331±82 mm Hg after trabeculectomy (P<0.001). The mean AL was 23.64±0.98 mm at baseline and 23.54±0.96 mm after trabeculectomy (P<0.001), whereas the mean OPP was 38.8±6.2 mm Hg preoperatively, and 51.1±7.3 mm Hg postoperatively (P<0.001). The change in CT negatively correlated with the change in IOP (r=−0.785, P<0.001) and AL (r=−0.693, P<0.001), whereas it positively correlated with the change in OPP (r=0.418, P=0.008). Conclusion These results suggest that the large IOP decrease following trabeculectomy causes choroidal thickening. In addition, CT changes are associated with IOP and AL reduction as well as OPP increase. PMID:23743533

    The 231-residue capsid (CA) protein of HIV-1 spontaneously self-assembles into tubes with a hexagonal lattice that is believed to mimic the surface lattice of conical capsid cores within intact virions. We report the results of solid state nuclear magnetic resonance (NMR) measurements on HIV-1 CA tubes that provide new information regarding changes in molecular structure that accompany CA self-assembly, local dynamics within CA tubes, and possible mechanisms for the generation of lattice curvature. This information is contained in site-specific assignments of signals in two- and three-dimensional solid state NMR spectra, conformation-dependent 15N and 13C NMR chemical shifts, detection of highly dynamic residues under solution NMR conditions, measurements of local variations in transverse spin relaxation rates of amide 1H nuclei, and quantitative measurements of site-specific 15N-15N dipole-dipole couplings. Our data show that most of the CA sequence is conformationally ordered and relatively rigid in tubular assemblies and that the structures of N-terminal and C-terminal domains (NTD and CTD) observed in solution are largely retained. However, specific segments, including the N-terminal β-hairpin, the cyclophilin A binding loop, the inter-domain linker, segments involved in intermolecular NTD-CTD interactions, and the C-terminal tail, have substantial static or dynamical disorder in tubular assemblies. Other segments, including the 310-helical segment in CTD, undergo clear conformational changes. Structural variations associated with curvature of the CA lattice appear to be localized in the inter-domain linker and intermolecular NTD-CTD interface, while structural variations within NTD hexamers, around local three-fold symmetry axes, and in CTD-CTD dimerization interfaces are less significant.

  4. One-way-coupling simulation of cavitation accompanied by high-speed droplet impact

    2016-03-01

    Erosion due to high-speed droplet impact is a crucial issue in industrial applications. The erosion is caused by the water-hammer loading on material surfaces and possibly by the reloading from collapsing cavitation bubbles that appear within the droplet. Here, we simulate the dynamics of cavitation bubbles accompanied by high-speed droplet impact against a deformable wall in order to see whether the bubble collapse is violent enough to give rise to cavitation erosion on the wall. The evolution of pressure waves in a single water (or gelatin) droplet to collide with a deformable wall at speed up to 110 m/s is inferred from simulations of multicomponent Euler flow where phase changes are not permitted. Then, we examine the dynamics of cavitation bubbles nucleated from micron/submicron-sized gas bubble nuclei that are supposed to exist inside the droplet. For simplicity, we perform Rayleigh-Plesset-type calculations in a one-way-coupling manner, namely, the bubble dynamics are determined according to the pressure variation obtained from the Euler flow simulation. In the simulation, the preexisting bubble nuclei whose size is either micron or submicron show large growth to submillimeters because tension inside the droplet is obtained through interaction of the pressure waves and the droplet interface; this supports the possibility of having cavitation due to the droplet impact. It is also found, in particular, for the case of cavitation arising from very small nuclei such as nanobubbles, that radiated pressure from the cavitation bubble collapse can overwhelm the water-hammer pressure directly created by the impact. Hence, cavitation may need to be accounted for when it comes to discussing erosion in the droplet impact problem.

    This study shows that a mitochondria-penetrating nitroxide probe (mito-TEMPO) allows detection of superoxide and visualization of mitochondrial dysfunction in living cells due to the effect of T1 shortening in MRI. Mitochondrial dysfunction was induced by treatment of cells with rotenone and 2-methoxyestradiol (2-ME/Rot). The MRI measurements were performed on 7T MRI. The 2-ME/Rot-treated cells were characterized by overproduction of superoxide, which was confirmed by a conventional dihydroethidium test. In the presence of mito-TEMPO, the intensity of MRI signal in 2-ME/Rot-treated cells was ∼30-40% higher, in comparison with that in untreated cells or culture media. In model (cell-free) systems, we observed that superoxide, but not hydrogen peroxide, increased the intensity of T1-weighted MRI signal of mito-TEMPO. Moreover, the superoxide restores the T1-weighted MRI contrast of mito-TEMPOH, a noncontrast (diamagnetic) analogue of mito-TEMPO. This was also confirmed by using EPR spectroscopy. The results demonstrate that superoxide radical is involved in the enhancement of T1-weighted MRI contrast in living cells, in the absence and presence of mito-TEMPO. This report gives a direction for discovering new opportunities for functional MRI, for detection of metabolic activity, accompanied by overproduction of superoxide, as well as by disturbance of the balance between superoxide and hydrogen peroxide, a very important approach to clarify the fine molecular mechanisms in the regulation of many pathologies. The visualization of mitochondrial activity in real-time can be crucial to clarify the molecular mechanism of the functional MRI in its commonly accepted definition, as a method for detection of neurovascular coupling.

    Relative humidity (PH2O, partial pressure of water)-dependent dehydration and accompanying phase transitions in NAT-topology zeolites (natrolite, scolecite, and mesolite) were studied under controlled temperature and known PH2O conditions by in situ diffuse-reflectance infrared Fourier transform spectroscopy and parallel X-ray powder diffraction. Dehydration was characterized by the disappearance of internal H2O vibrational modes. The loss of H2O molecules caused a sequence of structural transitions in which the host framework transformation path was coupled primarily via the thermal motion of guest Na?/Ca2? cations and H2O molecules. The observation of different interactions of H2O molecules and Na?/Ca2? cations with host aluminosilicate frameworks under highand low-PH2O conditions indicated the development of different local strain fields, arising from cation H2O interactions in NAT-type channels. These strain fields influence the Si O/Al O bond strength and tilting angles within and between tetrahedra as the dehydration temperature is approached. The newly observed infrared bands (at 2,139 cm-1 in natrolite, 2,276 cm-1 in scolecite, and 2,176 and 2,259 cm-1 in mesolite) result from strong cation H2O Al Si framework interactions in NAT-type channels, and these bands can be used to evaluate the energetic evolution of Na?/Ca2? cations before and after phase transitions, especially for scolecite and mesolite. The 2,176 and 2,259 cm-1 absorption bands in mesolite also appear to be related to Na?/Ca2? order disorder that occur when mesolite loses its Ow4 H2O molecules.

    Prion diseases are fatal neurodegenerative disorders characterized by accumulation of PrPSc, vacuolation of neurons and neuropil, astrocytosis, and microglial activation. Upregulation of gene expressions of innate immunity-related factors, including complement factors and CD14, is observed in the brains of mice infected with prions even in the early stage of infections. When CD14 knockout (CD14−/−) mice were infected intracerebrally with the Chandler and Obihiro prion strains, the mice survived longer than wild-type (WT) mice, suggesting that CD14 influences the progression of the prion disease. Immunofluorescence staining that can distinguish normal prion protein from the disease-specific form of prion protein (PrPSc) revealed that deposition of PrPSc was delayed in CD14−/− mice compared with WT mice by the middle stage of the infection. Immunohistochemical staining with Iba1, a marker for activated microglia, showed an increased microglial activation in prion-infected CD14−/− mice compared to WT mice. Interestingly, accompanied by the increased microglial activation, anti-inflammatory cytokines interleukin-10 (IL-10) and transforming growth factor β (TGF-β) appeared to be expressed earlier in prion-infected CD14−/− mice. In contrast, IL-1β expression appeared to be reduced in the CD14−/− mice in the early stage of infection. Double immunofluorescence staining demonstrated that CD11b- and Iba1-positive microglia mainly produced the anti-inflammatory cytokines, suggesting anti-inflammatory status of microglia in the CD14−/− mice in the early stage of infection. These results imply that CD14 plays a role in the disease progression by suppressing anti-inflammatory responses in the brain in the early stage of infection. PMID:24089559

    Purpose. To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. Methods. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb) and deoxyhemoglobin (DeoxyHb) levels were detected before and after treatment after 15, 30, and 45 days. Results. In this cohort, pretreatment OxyHb (mean ± SD) is 1.32 ± 0.14 (medium-high), and DeoxyHb is 0.87 ± 0.13 (normal). All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23 ± 0.09 (normal-medium, 15-day), 1.16 ± 0.08 (normal, 30-day), and 1.05 ± 0.04 (normal, 45-day), and DeoxyHb levels are 0.90 ± 0.11 (normal, 15-day), 0.94 ± 0.18 (normal, 30-day), and 0.98 ± 0.12 (normal, 45-day). Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Conclusion. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

    This case involved a 30-year-old woman who visited our hospital with the main complaint of protrusion of the maxillary incisors and upper and lower lips. She had difficulty closing her lips, and a chin button was observed when the lips were closed. The skeletal pattern showed maxillary protrusion and mandibular retrusion, and the mandible showed severe high angle. Labial inclination of both the maxillary and mandibular incisors was found, as well as crowding. In addition, the maxillary left second molar showed buccal displacement, and scissor bite was evident in the left second molar region. The bilateral molar relationship was cusp-to-cusp class II malocclusion. Angle class II maxillary protrusion accompanied by crowding and left second molar scissor bite was diagnosed. Surgical orthodontic treatment was judged as the best approach to treat the jaw deformities. However, in line with the wishes of the patient, treatment was undertaken using implant anchors instead. Straight-wire brackets with a 0.022-inch slot were fitted. A lingual arch was placed in the mandible and plate-type implant anchors in the first molar region of the maxilla. Almost no change was observed in skeletal pattern as no surgery was performed. The maxillary incisors moved back 10 mm, however, and the mandibular incisors showed an improvement of 4 mm from L1 to APo. The upper and lower lips consequently moved back 7 mm with respect to the E-line. Active treatment required 3 years and 6 months. Esthetic and functional improvements were achieved. PMID:26657523

    The interplay between epigenetic modification and chromatin compaction is implicated in the regulation of gene expression, and it comprises one of the most fascinating frontiers in cell biology. Although a complete picture is still lacking, it is generally accepted that the differentiation of embryonic stem (ES) cells is accompanied by a selective condensation into heterochromatin with concomitant gene silencing, leaving access only to lineage-specific genes in the euchromatin. ES cells have been reported to have less condensed chromatin, as they are capable of differentiating into any cell type. However, pluripotency itself—even prior to differentiation—is a split state comprising a naïve state and a state in which ES cells prime for differentiation. Here, we show that naïve ES cells decondense their chromatin in the course of downregulating the pluripotency marker Nanog before they initiate lineage commitment. We used fluorescence recovery after photobleaching, and histone modification analysis paired with a novel, to our knowledge, optical stretching method, to show that ES cells in the naïve state have a significantly stiffer nucleus that is coupled to a globally more condensed chromatin state. We link this biophysical phenotype to coinciding epigenetic differences, including histone methylation, and show a strong correlation of chromatin condensation and nuclear stiffness with the expression of Nanog. Besides having implications for transcriptional regulation and embryonic cell sorting and suggesting a putative mechanosensing mechanism, the physical differences point to a system-level regulatory role of chromatin in maintaining pluripotency in embryonic development.

    Infection of humans by hepatitis B virus (HBV) induces the copious production of antibodies directed against the capsid protein (Cp). A large variety of anticapsid antibodies have been identified that differ in their epitopes. These data, and the status of the capsid as a major clinical antigen, motivate studies to achieve a more detailed understanding of their interactions. In this study, we focused on the Fab fragments of two monoclonal antibodies, E1 and 3120. E1 has been shown to bind to the side of outward-protruding spikes whereas 3120 binds to the "floor" region of the capsid, between spikes. We used hydrogen-deuterium exchange coupled to mass spectrometry (HDX-MS) to investigate the effects on HBV capsids of binding these antibodies. Conventionally, capsids loaded with saturating amounts of Fabs would be too massive to be readily amenable to HDX-MS. However, by focusing on the Cp protein, we were able to acquire deuterium uptake profiles covering the entire 149-residue sequence and reveal, in localized detail, changes in H/D exchange rates accompanying antibody binding. We find increased protection of the known E1 and 3120 epitopes on the capsid upon binding and show that regions distant from the epitopes are also affected. In particular, the α2a helix (residues 24-34) and the mobile C-terminus (residues 141-149) become substantially less solvent-exposed. Our data indicate that even at substoichiometric antibody binding an overall increase in the rigidity of the capsid is elicited, as well as a general dampening of its breathing motions.

    Mutations in the PTRF/Cavin-1 gene cause congenital generalized lipodystrophy type 4 (CGL4) associated with myopathy. Additionally, long-QT syndrome and fatal cardiac arrhythmia are observed in patients with CGL4 who have homozygous PTRF/Cavin-1 mutations. PTRF/Cavin-1 deficiency shows reductions of caveolae and caveolin-3 (Cav3) protein expression in skeletal muscle, and Cav3 deficiency in the heart causes cardiac hypertrophy with loss of caveolae. However, it remains unknown how loss of PTRF/Cavin-1 affects cardiac morphology and function. Here, we present a characterization of the hearts of PTRF/Cavin-1-null (PTRF-/-) mice. Electron microscopy revealed the reduction of caveolae in cardiomyocytes of PTRF-/- mice. PTRF-/- mice at 16 weeks of age developed a progressive cardiomyopathic phenotype with wall thickening of left ventricles and reduced fractional shortening evaluated by echocardiography. Electrocardiography revealed that PTRF-/- mice at 24 weeks of age had low voltages and wide QRS complexes in limb leads. Histological analysis showed cardiomyocyte hypertrophy accompanied by progressive interstitial/perivascular fibrosis. Hypertrophy-related fetal gene expression was also induced in PTRF-/- hearts. Western blotting analysis and quantitative RT-PCR revealed that Cav3 expression was suppressed in PTRF-/- hearts compared with that in wild-type (WT) ones. ERK1/2 was activated in PTRF-/- hearts compared with that in WT ones. These results suggest that loss of PTRF/Cavin-1 protein expression is sufficient to induce a molecular program leading to cardiomyocyte hypertrophy and cardiomyopathy, which is partly attributable to Cav3 reduction in the heart.

    Prepulse inhibition (PPI) of the acoustic startle response is a measure of sensorimotor gating that is deficient in some neuropsychiatric disorders, such as schizophrenia and Tourette's syndrome. Experimentally induced PPI deficits in rats are regarded as endophenotype to study the biological mechanisms and therapeutic strategies of these disorders. We have recently shown that selectively breeding rats for high and low PPI levels, respectively, leads to groups with different PPI performance that remains stable from the second generation on. We here tested whether the low PPI is accompanied by other behavioral deficits. Different spatial and operant learning paradigms were used to assess rats' learning and memory abilities as well as their behavioral flexibility. In the delayed alternation T-maze task the two groups did not differ in task acquisition and working memory. Rats with low PPI showed enhanced perseveration during switching between an egocentric and allocentric radial maze task. Enhanced perseveration was also found in an operant behavioral task, where different demands, i.e. a different number of lever presses for a pellet-reward, were assigned to and switched between two levers of a Skinner box. Rats with low PPI stayed longer at the ineffective lever before switching, thus being less able to adjust their behavior to changing reward values. Additionally, PPI low rats had a higher breakpoint value during a progressive ratio-schedule of reinforcement. Rats selectively bred for low PPI showed some cognitive deficits that are apparent in a number of psychiatric disorders with deficient information processing. Specifically in both, spatial and operant behavioral paradigms, PPI low rats are deteriorated in their ability to modulate behavior based upon new changing information. They may thus provide a non-pharmacological model that can be used to evaluate new therapeutic strategies ranging from pharmacological treatment to functional neurosurgery. PMID:17693035

    Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery. PMID:26870237

    The combination of Müllerian agenesis with inguinal ovaries accompanied by primary ovarian insufficiency is extremely rare. A 21-year-old Korean woman was referred to our center with primary amenorrhea. The patient was diagnosed with Müllerian agenesis with inguinal ovaries. Her hormonal profile showed hypergonadotrophic hypogonadism suggesting primary ovarian insufficiency. We performed laparoscopic neovaginoplasty using modified Davydov's procedure and reposition inguinal ovaries in the pelvic cavity. Oral estrogen replacement was applied for the treatment of primary ovarian insufficiency. This is a rare case report on Mayer-Rokitansky-Kuster-Hauser syndrome accompanied not only by inguinal ovaries but also with primary ovarian insufficiency. We present our first experience on the laparoscopic neovaginoplasty performed on the patient with müllerian agenesis accompanied by inguinal ovaries and primary ovarian insufficiency. PMID:27462606

  17. Widespread Gravity Changes and CO2 Degassing at Laguna Del Maule, Chile, Accompanying Rapid Uplift

    Laguna Del Maule (LdM), located on the Andes range crest in central Chile, is one of the most active rhyolite volcanic fields on Earth with 36 post glacial rhyolitic eruptions. Since 2007, LdM has accumulated over 1.8 m of uplift at rates of up to 300 mm per year. We hypothesize that this rapid uplift results from the injection of basaltic magma into the base of a rhyolite chamber. To test this hypothesis we undertook a dynamic gravity study, complimented with CO2 soil gas measurements. We established a 35 station dynamic gravity and differential GPS network around the lake in April 2013 and undertook initial CO2 measurements. We resurveyed the network in January 2014 and expanded the soil gas coverage. From these surveys we calculated 0.134 ± 0.030 mGal residual gravity change (Δg) accompanied by 281 ± 13 mm of uplift over the 10 month period. Statistical tests show that the results of the 2013 and 2014 surveys are different at p < 0.01. The Δg anomaly occupies an area of 5 km x 10 km, oriented E/W, and centred in the south eastern part of the lake, and is coincident with the area of maximum uplift. Gaussian integration of Δg yields an excess mass of ~1.2 x 1011 kg. Assuming a density of 2700 kg/m3 this results in a volume of around 0.044 km3. In the 10 month time interval between surveys the calculated volume change rate was 41 ± 1 m3/s. We examine gravity / height change (Δg/Δh) relationships to determine if changes observed relate soley to increased mass or if density changes are involved. In addition to the Δg and Δh measurements, CO2 soil concentrations of up to 7 % are recorded around the entire lake basin. We will discuss modelling of the Δh and Δg data to explore the geometry and physical parameters of the mass and pressure source and discuss the relationship of CO2 anomalies to these models.

  18. Molecular evolution accompanying functional divergence of duplicated genes along the plant starch biosynthesis pathway

    PubMed Central

    2014-01-01

    Background Starch is the main source of carbon storage in the Archaeplastida. The starch biosynthesis pathway (sbp) emerged from cytosolic glycogen metabolism shortly after plastid endosymbiosis and was redirected to the plastid stroma during the green lineage divergence. The SBP is a complex network of genes, most of which are members of large multigene families. While some gene duplications occurred in the Archaeplastida ancestor, most were generated during the sbp redirection process, and the remaining few paralogs were generated through compartmentalization or tissue specialization during the evolution of the land plants. In the present study, we tested models of duplicated gene evolution in order to understand the evolutionary forces that have led to the development of SBP in angiosperms. We combined phylogenetic analyses and tests on the rates of evolution along branches emerging from major duplication events in six gene families encoding sbp enzymes. Results We found evidence of positive selection along branches following cytosolic or plastidial specialization in two starch phosphorylases and identified numerous residues that exhibited changes in volume, polarity or charge. Starch synthases, branching and debranching enzymes functional specializations were also accompanied by accelerated evolution. However, none of the sites targeted by selection corresponded to known functional domains, catalytic or regulatory. Interestingly, among the 13 duplications tested, 7 exhibited evidence of positive selection in both branches emerging from the duplication, 2 in only one branch, and 4 in none of the branches. Conclusions The majority of duplications were followed by accelerated evolution targeting specific residues along both branches. This pattern was consistent with the optimization of the two sub-functions originally fulfilled by the ancestral gene before duplication. Our results thereby provide strong support to the so-called “Escape from Adaptive Conflict

    initial bottleneck. Both ABC analyses and measures of mtDNA sequence diversity also suggested that population reductions were more severe in the black lava compared to the white sands habitat. Differences observed between habitats may be explained by differences in colonization time, habitat geometry, and strength or response to natural selection for substrate matching. Finally, effective population size reductions in this system appear to be more dramatic when colonization is accompanied by a change in selection regime. Our analyses are consistent with a demographic cost of adaptation to novel environments and show that it is possible to infer aspects of the historical demography of local adaptation even in the presence of ongoing gene flow.

    ABSTRACT Highly pathogenic avian influenza viruses (HPAIVs) of hemagglutinin H5 and H7 subtypes emerge after introduction of low-pathogenic avian influenza viruses (LPAIVs) from wild birds into poultry flocks, followed by subsequent circulation and evolution. The acquisition of multiple basic amino acids at the endoproteolytical cleavage site of the hemagglutinin (HA) is a molecular indicator for high pathogenicity, at least for infections of gallinaceous poultry. Apart from the well-studied significance of the multibasic HA cleavage site, there is only limited knowledge on other alterations in the HA and neuraminidase (NA) molecules associated with changes in tropism during the emergence of HPAIVs from LPAIVs. We hypothesized that changes in tropism may require alterations of the sialyloligosaccharide specificities of HA and NA. To test this hypothesis, we compared a number of LPAIVs and HPAIVs for their HA-mediated binding and NA-mediated desialylation of a set of synthetic receptor analogs, namely, α2-3-sialylated oligosaccharides. NA substrate specificity correlated with structural groups of NAs and did not correlate with pathogenic potential of the virus. In contrast, all HPAIVs differed from LPAIVs by a higher HA receptor-binding affinity toward the trisaccharides Neu5Acα2-3Galβ1-4GlcNAcβ (3′SLN) and Neu5Acα2-3Galβ1-3GlcNAcβ (SiaLec) and by the ability to discriminate between the nonfucosylated and fucosylated sialyloligosaccharides 3′SLN and Neu5Acα2-3Galβ1-4(Fucα1-3)GlcNAcβ (SiaLex), respectively. These results suggest that alteration of the receptor-binding specificity accompanies emergence of the HPAIVs from their low-pathogenic precursors. IMPORTANCE Here, we have found for the first time correlations of receptor-binding properties of the HA with a highly pathogenic phenotype of poultry viruses. Our study suggests that enhanced receptor-binding affinity of HPAIVs for a typical “poultry-like” receptor, 3′SLN, is provided by

  12. Iconic gestures prime words: comparison of priming effects when gestures are presented alone and when they are accompanying speech

    PubMed Central

    So, Wing-Chee; Yi-Feng, Alvan Low; Yap, De-Fu; Kheng, Eugene; Yap, Ju-Min Melvin

    2013-01-01

    Previous studies have shown that iconic gestures presented in an isolated manner prime visually presented semantically related words. Since gestures and speech are almost always produced together, this study examined whether iconic gestures accompanying speech would prime words and compared the priming effect of iconic gestures with speech to that of iconic gestures presented alone. Adult participants (N = 180) were randomly assigned to one of three conditions in a lexical decision task: Gestures-Only (the primes were iconic gestures presented alone); Speech-Only (the primes were auditory tokens conveying the same meaning as the iconic gestures); Gestures-Accompanying-Speech (the primes were the simultaneous coupling of iconic gestures and their corresponding auditory tokens). Our findings revealed significant priming effects in all three conditions. However, the priming effect in the Gestures-Accompanying-Speech condition was comparable to that in the Speech-Only condition and was significantly weaker than that in the Gestures-Only condition, suggesting that the facilitatory effect of iconic gestures accompanying speech may be constrained by the level of language processing required in the lexical decision task where linguistic processing of words forms is more dominant than semantic processing. Hence, the priming effect afforded by the co-speech iconic gestures was weakened. PMID:24155738
