    The future of the Department of Energy's Defense Program (DP) laboratories-Los Alamos, Livermore, and Sandia-has been extensively debated and examined over the past several years. To assist in this process, I have asked that a set of documents be prepared, which, when taken together, present a comprehensive picture of the three laboratories. This document describes the multiprogram nature of the DP laboratories and the value of their involvement in non-DP work as it relates to the nuclear weapons program. The other two documents, Integration and Collaboration.. Solving Science and Technology Problems for the Nation (DOE/DP-96009797) and Roles and Responsibilities of the Department of Energy Nuclear Weapons Laboratories in the Stockpile Stewardship and Management Program (DOE/DP-97000280), describe respectively the integrated nature of the DP laboratories and the roles of the laboratories as they meet their individual and collective responsibilities of ensuring the safety and reliabilities of the U.S. nuclear weapons stockpile.

    Techniques are disclosed for loading programs efficiently in a parallel computing system. In one embodiment, nodes of the parallel computing system receive a load description file which indicates, for each program of a multiple program multiple data (MPMD) job, nodes which are to load the program. The nodes determine, using collective operations, a total number of programs to load and a number of programs to load in parallel. The nodes further generate a class route for each program to be loaded in parallel, where the class route generated for a particular program includes only those nodes on which the program needs to be loaded. For each class route, a node is selected using a collective operation to be a load leader which accesses a file system to load the program associated with a class route and broadcasts the program via the class route to other nodes which require the program.

    Few would argue that maintenance is not a problem. Practices do not eliminate problems, but only proper practice makes perfect maintenance. To master management of building services maintenance, there is no better teacher than experience. You must plan your maintenance system thoughtfully and try it out together with your professional knowledge. The system outlined in this article gives a systematic procedure in setting up a workable maintenance plan. The tedious management work and the inconvenience caused to a busy or new maintenance department will probably mean greater pressure of work for the maintenance engineer in the first year, but thereafter the pressure will be less than before and benefits of an organised system of maintenance will repay the effort of introducing it. It is essential that the paperwork be as simple as possible and very flexible in operation so that amendments can be made easily. Preparation of paperwork is by no means easy. It is highly likely that your schedules and programmes will have to be rewritten two or three times before arriving at the optimum plan. My management lecturer once told me: "Without a plan and a programme, you don't know whether you have done all the things that you need to do, and you will end up with many problems." Good planning gives you confidence, but take my advice--do not over plan. Too much paperwork can be just as bad if not worse than too little paper. Information will be of no use if it cannot be read, digested and used in practice.

    2000-01-01

    The tremors of Parkinson's disease (PD) and essential tremor (ET) are traditionally considered to depend on a central oscillator producing rhythmic activation of the motoneurones of all extremities. To test this hypothesis, we have compared electromyographic tremor activity in different muscles of the affected limbs using cross spectral analysis, including coherence and phase. Surface electromyographic recordings from both arms, legs, and the neck were analyzed in 22 patients with PD and 28 patients with ET. Volume conduction between neighboring muscles producing artificial "coherence" has been found to be an important methodologic problem. We have developed a mathematical test to exclude data that could distort the results. According to this test, 10% or 25% of muscle combinations from the same limb had to be excluded from further analysis in PD or ET, respectively. In both, patients with PD and ET, we found a considerable number of muscle combinations oscillating at virtually the same frequency (delta frequency <0.4 Hz) without showing a significant coherence. Thus, the frequency difference between different muscles is not sufficient to measure the correlation between two muscles. Significant coherencies between muscles within the same arm or leg were found in 70% or 90% of patients with PD or ET, respectively, whereas only one patient with PD and not a single patient with ET showed significant coherencies between muscles from different limbs. The phase between coherent muscles of the same arm of patients with PD showed a preference of either a reciprocal alternating pattern for antagonistic muscles in forearm flexor and upper arm extensor as opposed to a co-contraction pattern between the hand flexors and the triceps brachii. In patients with ET such clear differences were lacking. We conclude that multiple oscillators are responsible for the tremor in different extremities of patients with PD and ET. Differences between PD and ET concerning the phase relation

    Essential functions (EF) define the nonacademic criteria used to determine an individual's qualifications for admission and capabilities of performing in the classroom and laboratory with or without reasonable accommodations. Directors of NAACLS approved and accredited programs were surveyed to investigate their knowledge and perceptions of EF and associations with disabilities and student behaviors. This was a non-experimental survey consisting of questions related to the use of essential functions (EF) and student behaviors in NAACLS laboratory programs. SurveyMonkey was used to electronically provide the survey of 33 questions to 564 NAACLS programs. Descriptive statistics were reported as aggregate data with a response rate of 267 (47.3%). EF are utilized in 95.5% of the programs; however, only 38.6% of the participants responded that EF are required by both the ADA and NAACLS. A student had never been dismissed based on EF in 80.0% of the programs. Many programs have been successful in mentoring students with disabilities to successful completion. Hearing impairment was the most reported disability (30.0%). Participants felt most comfortable referring students for academic coaching (96.2%) when compared to medical concerns (86.5%), and psychological concerns (82.7%). While most programs utilized EF, many program directors were not aware that EF are required by both NAACLS and the ADA. Programs have successfully instructed and graduated students with a variety of disabilities and generally feel comfortable in referring students for assistance. Concerns with inappropriate behaviors present unique, generational challenges to faculty.

    Education for health care workers on pain-related topics is not always readily available, and this is especially so in low and middle income countries (LMICs). The Essential Pain Management program (EPM) has been developed to offer a simple interactive educational opportunity for health care workers in LMICs. Following a needs analysis in Papua New Guinea, an 8 h educational program with the aims of improving pain knowledge and providing a simple pain management framework was developed. An evaluation of the program using the Kirkpatrick model is being used. The program has a "teach the teachers" component to encourage sustainability. The program has been run in 30 countries, delivered to 1,600 participants, and 340 instructors have been trained. Feedback has been positive, pre post testing in 27 sites showed a mean pre score of 65.89% rising to 75.23% (n = 581 respondents). A subanalysis demonstrates doctors and nurses improving by similar degrees. When local instructors have delivered the program after attending the trainer's session the participant test results were comparable to the results seen when the overseas instructors taught the course. The widespread adoption of the EPM program suggests there is a need for pain education in LMICs. The teach the teachers component of the program and the comparable results from their teaching should contribute to sustainability. Further support and mentoring using electronic systems such as Facebook, text messaging, and a website may also contribute to sustainability.

  13. Successful healthcare programs and projects: organization portfolio management essentials.

    2005-01-01

    Many healthcare organization projects take more time and resources than planned and fail to deliver desired business outcomes. Healthcare IT is a major component of many projects and often undeservedly receives the blame for failure. Poor results are often not a result of faulty healthcare IT or poor project management or poor project execution alone. Many projects fail because of poor portfolio management--poor planning and management of the portfolio of initiatives designed to meet an organization's strategic goals. Because resources are limited, portfolio management enables organizations to more strategically allocate and manage their resources so care delivery, service delivery, and initiatives that advance organizations toward their strategic goals, including healthcare IT initiatives, can be accomplished at the levels of quality and service desired by an organization. Proper portfolio management is the essential foundation for program and project success and supports overall organization success. Without portfolio management, even programs and projects that execute flawlessly may not meet desired objectives. This article discusses the essential requirements for porfolio management. These include opportunity identification, return on investment (ROI) forecast, project prioritization, capacity planning (inclusive of human, financial, capital, and facilities resources), work scheduling, program and project management and execution, and project performance and value assessment. Portfolio management is essential to successful healthcare project execution. Theories are drawn from the Organizational Project Management Maturity Model (OPM3) work of the Project Management Institute and other leading strategy, planning, and organization change management research institutes.

    Essential Care for Every Baby (ECEB) is an evidence-based educational program designed to increase cognitive knowledge and develop skills of health care professionals in essential newborn care in low-resource areas. The course focuses on the immediate care of the newborn after birth and during the first day or until discharge from the health facility. This study assessed the overall design of the course; the ability of facilitators to teach the course; and the knowledge and skills acquired by the learners. Testing occurred at 2 global sites. Data from a facilitator evaluation survey, a learner satisfaction survey, a multiple choice question (MCQ) examination, performance on two objective structured clinical evaluations (OSCE), and pre- and post-course confidence assessments were analyzed using descriptive statistics. Pre-post course differences were examined. Comments on the evaluation form and post-course group discussions were analyzed to identify potential program improvements. Using ECEB course material, master trainers taught 12 facilitators in India and 11 in Kenya who subsequently taught 62 providers of newborn care in India and 64 in Kenya. Facilitators and learners were satisfied with their ability to teach and learn from the program. Confidence (3.5 to 5) and MCQ scores (India: pre 19.4, post 24.8; Kenya: pre 20.8, post 25.0) improved (p < 0.001). Most participants demonstrated satisfactory skills on the OSCEs. Qualitative data suggested the course was effective, but also identified areas for course improvement. These included additional time for hands-on practice, including practice in a clinical setting, the addition of video learning aids and the adaptation of content to conform to locally recommended practices. ECEB program was highly acceptable, demonstrated improved confidence, improved knowledge and developed skills. ECEB may improve newborn care in low resource settings if it is part of an overall implementation plan that addresses local needs and

    In 2008, the American College of Clinical Pharmacy appointed the Task Force on Research in the Professional Curriculum to review and make recommendations on the essential research curriculum that should be part of doctor of pharmacy (Pharm.D.) degree programs. The essential research curriculum provides all students with critical and analytical thinking and lifelong learning skills, which will apply to current and future practice and stimulate some students to pursue a career in this field. Eight key curricular competencies are as follows: identifying relevant problems and gaps in pharmacotherapeutic knowledge; generating a research hypothesis; designing a study to test the hypothesis; analyzing data results using appropriate statistical tests; interpreting and applying the results of a research study to practice; effectively communicating research and clinical findings to pharmacy, medical, and basic science audiences; interpreting and effectively communicating research and clinical findings to patients and caregivers; and applying regulatory and ethical principles when conducting research or using research results. Faculty are encouraged to use research-related examples across the curriculum in nonresearch courses and to employ interactive teaching methods to promote student engagement. Examples of successful strategies used by Pharm.D. degree programs to integrate research content into the curriculum are provided. Current pharmacy school curricula allow variable amounts of time for instructional content in research, which may or may not include hands-on experiences for students to develop research-related skills. Therefore, an important opportunity exists for schools to incorporate the essential research curriculum. Despite the challenges of implementing these recommendations, the essential research curriculum will position pharmacy school graduates to understand the importance of research and its applications to practice. This perspective is provided as an aid

    Monoclonal antibodies (mAbs) are now established as targeted therapies for malignancies, transplant rejection, autoimmune and infectious diseases. Two monoclonal antibodies are available for treatment and other antibodies are currently being tested in multiple sclerosis (MS) patients. The purpose of the present review paper is to outline the antibody engineering technologies, the immunologic and pharmacologic concepts of mΑbs and the current status of treatment in MS with emphasis on clinical efficacy and safety. We conducted a thorough review of the scientific literature published until 31 December 2014 (print and electronic publications) concerning the production, applications and side effects of the use of Mabs. Sixty five articles were used in total (both original research and review papers). With the introduction of mAbs the treatment of MS has entered a new era, both with respect to efficacy and target specificity. However, administration of mAbs carries the risk of immune reactions such as acute anaphylaxis, serum sickness a, infection and other autoimmune diseases. In addition, unexpected consequences arise from our incomplete knowledge of the immune system. For example, natalizumab, a monoclonal antibody targeting α4-integrin on leukocytes increases the risk of developing progressive multifocal leukoencephalopathy, without causing notable immunosuppression. Further study on the use of mabs is required, both in vitro and in the clinical field, in order to increase our knowledge upon these new revolutionary therapeutic agents.

    The advent of heme during evolution allowed organisms possessing this compound to safely and efficiently carry out a variety of chemical reactions that otherwise were difficult or impossible. While it was long assumed that a single heme biosynthetic pathway existed in nature, over the past decade, it has become clear that there are three distinct pathways among prokaryotes, although all three pathways utilize a common initial core of three enzymes to produce the intermediate uroporphyrinogen III. The most ancient pathway and the only one found in the Archaea converts siroheme to protoheme via an oxygen-independent four-enzyme-step process. Bacteria utilize the initial core pathway but then add one additional common step to produce coproporphyrinogen III. Following this step, Gram-positive organisms oxidize coproporphyrinogen III to coproporphyrin III, insert iron to make coproheme, and finally decarboxylate coproheme to protoheme, whereas Gram-negative bacteria first decarboxylate coproporphyrinogen III to protoporphyrinogen IX and then oxidize this to protoporphyrin IX prior to metal insertion to make protoheme. In order to adapt to oxygen-deficient conditions, two steps in the bacterial pathways have multiple forms to accommodate oxidative reactions in an anaerobic environment. The regulation of these pathways reflects the diversity of bacterial metabolism. This diversity, along with the late recognition that three pathways exist, has significantly slowed advances in this field such that no single organism's heme synthesis pathway regulation is currently completely characterized.

    As the number of prison inmates facing end-stage chronic illness grows, more prisons across the U.S. must address the need for end-of-life care. Many will likely need to develop a plan with potentially limited resources and external support. This case study presents one long-running model of care, the Louisiana State Penitentiary Prison Hospice Program. Based on field observations and in-depth interviews with hospice staff, inmate volunteers and corrections officers, we identify five essential elements that have contributed to the long-term operation of this program: patient-centered care, an inmate volunteer model, safety and security, shared values, and teamwork. We describe key characteristics of each of these elements, discuss how they align with earlier recommendations and research, and show how their integration supports a sustained model of prison end-of-life care.

    2001-12-01

    Multiple-objective programming was used to examine the effects various objectives had on the optimal portfolio of sires chosen for a given breeding problem in a Jersey cow dairy herd. It was assumed that the dairy producer had the following three objectives in the breeding decision: to maximize Net Merit, to minimize inbreeding, and to minimize total expenditure on semen. Integer programming models of these three single objectives were estimated to provide the ideal and anti-ideal values for use in several multiple-objective programming models. The integer multiple-objective models examined the interactions and costs of tradeoffs between the three single objectives in a model framework designed to minimize the maximum deviations from the single-objective optima. A model with equal weights on each objective resulted in a decrease of 3% in average inbreeding but also reduced average Net Merit by $170 from the single-objective optima. A second model, where the weight on Net Merit was twice that of inbreeding and semen cost, decreased Net Merit by $100 and reduced inbreeding by 2% from the single objective optima. The results of the multiple-objective programming models show that reducing the inbreeding coefficient for a group of sires purchased will decrease the Net Merit. However, the results generated also demonstrate that the weights placed on each objective by the dairy producer substantially affect the optimal levels of each objective within the multiple-objective model.

    Ocean Networks Canada (ONC) uses a number of research and exploration vessels equipped with remotely operated vehicles (ROVs) to maintain the NEPTUNE and VENUS cabled ocean observatories off the west coast of British Columbia, Canada. Maintenance expeditions range from several days to multiple weeks and encompass a range of activities including deploying new instruments, laying cable, recovering platforms, scientific sampling and conducting multibeam and visual surveys. In order to engage the widest possible participation in at-sea work, ONC uses telepresence technology to communicate from ship to shore and back with scientists, students, teachers and online viewers. In this presentation, we explore the challenge of designing a sustainable and flexible telepresence program which can be supported across multiple ship and ROV platforms, sometimes simultaneously. To meet outreach and education objectives, onboard educators conduct presentations to K-12 and post-secondary classrooms, museums and science centres on a daily basis. Online commentary by the educators, dive chief and ROV pilots accompanies the ROV dive footage and is streamed online 24/7 during underwater operations. Sharing the sights and sounds of the expeditions with students and educators ashore, including those in remote and inland communities, creates a unique learning environment for both formal and informal education audiences. As space is always a limiting factor on expeditions, the use of telepresence and other communication media enables ONC to simultaneously achieve engineering and science priorities at sea while communicating the successes and challenges of the expedition back to shore. Scientists and engineers provide guidance for operations from shore using a variety of communication technologies. We give examples from Ocean Networks Canada's most recent expedition, Fall 2015, which involved co-ordinated operations with three vessels - the R/V Thompson, the E/V Nautilus and the C/S Wave

    Parallelization of molecular dynamics (MD) simulation is essential for investigating conformational dynamics of large biological systems, such as ribosomes, viruses, and multiple proteins in cellular environments. To improve efficiency in the parallel computation, we have to reduce the amount of data transfer between processors by introducing domain decomposition schemes. Also, it is important to optimize the computational balance between real-space non-bonded interactions and reciprocal-space interactions for long-range electrostatic interactions. Here, we introduce a novel parallelization scheme for large-scale MD simulations on massively parallel supercomputers consisting of only CPUs. We make use of a multiple program/multiple data (MPMD) approach for separating the real-space and reciprocal-space computations on different processors. We also utilize the r-RESPA multiple time step integrator on the framework of the MPMD approach in an efficient way: when the reciprocal-space computations are skipped in r-RESPA, processors assigned for them are utilized for half of the real-space computations. The new scheme allows us to use twice as many as processors that are available in the conventional single program approach. The best performances of all-atom MD simulations for 1 million (STMV), 8.5 million (8_STMV), and 28.8 million (27_STMV) atom systems on K computer are 65, 36, and 24 ns/day, respectively. The MPMD scheme can accelerate 23.4, 10.2, and 9.2 ns/day from the maximum performance of single-program approach for STMV, 8_STMV, and 27_STMV systems, respectively, which correspond to 57%, 39%, and 60% speed up. This suggests significant speedups by increasing the number of processors without losing parallel computational efficiency. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Formal guidelines for mentoring faculty members in pharmacy practice divisions of colleges and schools of pharmacy do not exist in the literature. This paper addresses the background literature on mentoring programs, explores the current state of mentoring programs used in pharmacy practice departments, and provides guidelines for colleges and schools instituting formal mentoring programs. As the number of pharmacy colleges and schools has grown, the demand for quality pharmacy faculty members has dramatically increased. While some faculty members gain teaching experience during postgraduate residency training, new pharmacy practice faculty members often need professional development to meet the demands of their academic responsibilities. A mentoring program can be 1 means of improving faculty success and retention. Many US colleges and schools of pharmacy have developed formal mentoring programs, whereas several others have informal processes in place. This paper discusses those programs and the literature available, and makes recommendations on the structure of mentoring programs. PMID:23519448

    Hafner, Ch.

    1995-05-01

    The three-dimensional multiple multipole program (MMP) code based on the generalized multipole technique is outlined for readers who are not familiar with its concepts. This code was originally designed for computational electromagnetics. Rayleigh expansions and periodic boundary conditions are two new features that make MMP computations of arbitrary periodic structures efficient and that at the same time allow us to take advantage of the benefits of other MMP features, including surface impedance boundary conditions and a variety of available basis functions for modeling the electromagnetic field. The application of three-dimensional MMP to a simple grating of highly conducting wires with rectangular cross sections illustrates the high accuracy and the fast convergence of the method as well as the use of surface impedance boundary conditions. A more complicated biperiodic array of helical antennas demonstrates the application of thin-wire expansions in conjunction with regular MMP expansions. This model can be considered a simulation of a thin, anisotropic chiral slab with interesting characteristics.

Since 2006, the program has recruited 50 doctoral students from ten traditional science, technology, and engineering disciplines to participate in the 2-year specialization program. Each trainee received mentoring from two or more individuals, including faculty members outside the student's home department and faculty members at other academic institutions, and/or clinicians. Both students and faculty members reported a significant increase in interdisciplinary scholarly activities, including publications, presentations, and funded research proposals, as a direct result of the program. Nearly 90% of students graduating with a specialization in nanomedicine have continued on to careers in the health care sector. Currently, 43% of graduates are performing research or developing products that directly involve nanomedicine. This article identifies some key elements of the Nanomedicine program, describes how they were implemented, and reports on the metrics of success.

    Investigation of essential genes is significant to comprehend the minimal gene sets of cell and discover potential drug targets. In this study, a novel approach based on multiple homology mapping and machine learning method was introduced to predict essential genes. We focused on 25 bacteria which have characterized essential genes. The predictions yielded the highest area under receiver operating characteristic (ROC) curve (AUC) of 0.9716 through tenfold cross-validation test. Proper features were utilized to construct models to make predictions in distantly related bacteria. The accuracy of predictions was evaluated via the consistency of predictions and known essential genes of target species. The highest AUC of 0.9552 and average AUC of 0.8314 were achieved when making predictions across organisms. An independent dataset from Synechococcus elongatus, which was released recently, was obtained for further assessment of the performance of our model. The AUC score of predictions is 0.7855, which is higher than other methods. This research presents that features obtained by homology mapping uniquely can achieve quite great or even better results than those integrated features. Meanwhile, the work indicates that machine learning-based method can assign more efficient weight coefficients than using empirical formula based on biological knowledge.

  18. Essential reduction of stitching errors in electron-beam lithography using a multiple-exposure technique

    Steingrueber, Ralf; Engel, Herbert; Lessle, Werner

    2001-08-01

    Electron-beam lithography is the technique of choice to generate in a flexible and accurate way structures and components in the micrometer region and below. Due to its particular exposure strategy, i.e. matching equidistant subfields to a complete pattern, electron-beam systems show typical displacement effects known as stitching errors. These errors can be of dramatic disturbance if they occur in high resolution patterns. This paper presents an exposure scheme which essentially reduces stitching errors by using a multiple exposure technique. The influence of this technique on the value of stitching errors and its interference with the process window as well as total processing time is reported.

    In this study, an o/w/o multiple emulsion/ionic gelation method was developed for production of alginate microparticles loaded with Satureja hortensis essential oil (SEO). It was found that the essential oil concentration has significant influence on encapsulation efficiency (EE), loading capacity (LC) and size of microparticles. The values of EE, LC and particle mean diameter were about 52-66%, 20-26%, and 47-117 μm, respectively, when the initial SEO content was 1-3% (v/v) .The essential oil-loaded microparticles were porous, as displayed by scanning electron micrograph. The presence of SEO in alginate microparticles was confirmed by Fourier transform-infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC) analyses. SEO-loaded microparticles showed good antioxidant (with DPPH radical scavenging activity of 40.7-73.5%) and antibacterial properties; this effect was greatly improved when the concentration of SEO was 3% (v/v). S. aureus was found to be the most sensitive bacterium to SEO and showed a highest inhibition zone of 304.37 mm(2) in the microparticles incorporated with 3% (v/v) SEO. In vitro release studies showed an initial burst release and followed by a slow release. In addition, the release of SEO from the microparticles followed Fickian diffusion with acceptable release.

    2015-10-01

    Hypertension is recognized as one of the major contributing factors to cardiovascular disease, but its etiology remains incompletely understood. Known genetic and environmental influences can only explain a small part of the variability in cardiovascular disease risk. The missing heritability is currently one of the most important challenges in blood pressure and hypertension genetics. Recently, some promising approaches have emerged that move beyond the DNA sequence and focus on identification of blood pressure genes regulated by epigenetic mechanisms such as DNA methylation, histone modification and microRNAs. This review summarizes information on gene-environmental interactions that lead toward the developmental programming of hypertension with specific reference to epigenetics and provides pediatricians and pediatric cardiologists with a more complete understanding of its pathogenesis.

    FORTRAN applications programs can be executed on multiprocessor computers in either a unitasking (traditional) or multitasking form. The latter allows a single job to use more than one processor simultaneously, with a consequent reduction in wall-clock time and, perhaps, the cost of the calculation. An introduction to programming in this environment is presented. The concepts of synchronization and data sharing using EVENTS and LOCKS are illustrated with examples. The strategy of strong synchronization and the use of synchronization templates are proposed. We emphasize that incorrect multitasking programs can produce irreproducible results, which makes debugging more difficult.

    Participation in research during undergraduate studies may increase students' interest in research and inculcate research essentials in them. The purpose of this study was to evaluate the effectiveness of the mentored student project (MSP) program. In the MSP program, students in groups (n = 3 to 5) undertook a research project, wrote a scholarly report, and presented the work as a poster presentation with the help of a faculty mentor. To begin with, the logic model of the program was developed to identify short-term outcomes of the program on students, mentors, and the institution. A quasi-experimental design was used to measure the outcomes. A mixed method evaluation was done using a newly-developed questionnaire to assess the impact of the MSP on students' attitude, a multiple-choice question (MCQs) test to find out the impact on students' knowledge and grading of students' project reports and posters along with a survey to check the impact on skills. Students' satisfaction regarding the program and mentors' perceptions were collected using questionnaires. Evidence for validity was collected for all the instruments used for the evaluation. Non-parametric tests were used to analyze data. Based on the scores, project reports and posters were graded into A (>70% marks), B (60-69% marks), and C (<59% marks) categories. The number of MSPs that resulted in publications, conference presentation and departmental collaborations were taken as impact on the institution. Students' response rate was 91.5%. The students' attitudes regarding research changed positively (P = 0.036) and score in the MCQ test improved (P < 0.001) after undertaking MSP. Majority of project reports and posters were of grade A category. The majority of the items related to skills gained and satisfaction had a median score of 4.

    The increasing recognition of the important role of calcium in the myriad regulation of cellular processes in the health and well being throughout one's lifetime has focused on the need to ensure a sufficiency of its intake for nutritional, physiological, and medical reasons. Additionally, the recognition of the dynamic dietary changes and preferences of various populations in terms of their consumption of calcium-containing products coupled with large variations of food patterns and availability of calcium, highlights the need to consider and evaluate multiple sources of calcium (dairy, non-dairy, fortified foods, and supplemental). Aspects of the essentiality of calcium are thus considered via an initial consideration of: the salient aspects of absorption and bioavailability, changes in individual and societal dietary habits and preferences and the evaluation of various RDAs, AIs, and DRIs for calcium.

    In multiple sulfatase deficiency (MSD), a human inherited disorder, the activities of all sulfatases are impaired due to a defect in posttranslational modification. Here we report the identification, by functional complementation using microcell-mediated chromosome transfer, of a gene that is mutated in MSD and is able to rescue the enzymatic deficiency in patients' cell lines. Functional conservation of this gene was observed among distantly related species, suggesting a critical biological role. Coexpression of SUMF1 with sulfatases results in a strikingly synergistic increase of enzymatic activity, indicating that SUMF1 is both an essential and a limiting factor for sulfatases. These data have profound implications on the feasibility of enzyme replacement therapy for eight distinct inborn errors of metabolism.

    2009-01-01

    Francisella tularensis is a highly infectious bacterium causing the zoonotic disease tularemia. Its ability to multiply and survive in macrophages is critical for its virulence. By screening a bank of HimarFT transposon mutants of the F. tularensis live vaccine strain (LVS) to isolate intracellular growth-deficient mutants, we selected one mutant in a gene encoding a putative gamma-glutamyl transpeptidase (GGT). This gene (FTL_0766) was hence designated ggt. The mutant strain showed impaired intracellular multiplication and was strongly attenuated for virulence in mice. Here we present evidence that the GGT activity of F. tularensis allows utilization of glutathione (GSH, gamma-glutamyl-cysteinyl-glycine) and gamma-glutamyl-cysteine dipeptide as cysteine sources to ensure intracellular growth. This is the first demonstration of the essential role of a nutrient acquisition system in the intracellular multiplication of F. tularensis. GSH is the most abundant source of cysteine in the host cytosol. Thus, the capacity this intracellular bacterial pathogen has evolved to utilize the available GSH, as a source of cysteine in the host cytosol, constitutes a paradigm of bacteria-host adaptation.

  17. The emergence of non-secretory multiple myeloma during the non-cytotoxic treatment of essential thrombocythemia: a case report

    PubMed Central

    2013-01-01

    Introduction The emergence of multiple myeloma as a second malignancy in patients with essential thrombocythemia is extremely rare. Several cases have been published so far, pointing out the impact of a cytotoxic effect during treatment of essential thrombocythemia on the development of multiple myeloma. Case presentation We report the case of a 52-year-old Caucasian man who presented to our hospital because of leukocytosis, a slightly decreased hemoglobin level and thrombocytosis. After a complete hematological work-up, essential thrombocythemia was diagnosed. The patient was included in a multicenter clinical study, treated with anagrelide and his platelet counts were maintained in the normal range for more than 3 years. A sudden drop in his hemoglobin level with normal leukocyte and platelet count occurred at the same time as a back pain. Magnetic resonance imaging of his spine revealed the existence of a pathological fracture of Th4, the collapse of the upper edge of Th7 and osteolytic lesions of multiple thoracic vertebrae. Repeated hematological examinations, including bone biopsy with immunohistochemistry, disclosed diagnosis of multiple myeloma of the non-secretory type. Conclusions To the best of our knowledge this is the first published case in which multiple myeloma developed during the treatment of essential thrombocythemia with the non-cytotoxic drug anagrelide. Our attempts to find a common origin for the coexistence of multiple myeloma and essential thrombocythemia have not confirmed the genetic basis of their appearance. Further studies are needed to determine the biological impact of this coexistence. PMID:24025541

    We present a practical branch and bound algorithm for globally solving generalized linear multiplicative programming problem with multiplicative constraints. To solve the problem, a relaxation programming problem which is equivalent to a linear programming is proposed by utilizing a new two-phase relaxation technique. In the algorithm, lower and upper bounds are simultaneously obtained by solving some linear relaxation programming problems. Global convergence has been proved and results of some sample examples and a small random experiment show that the proposed algorithm is feasible and efficient.

    Essential hypertension is a principal cardiovascular risk factor whose origin remains unknown. Classical genetic studies have shown that blood pressure is at least partially heritable, opening a window to understanding the pathophysiology of essential hypertension in the human using modern genetic tools. The Wellcome Trust Case Control Consortium has recently published the results of screening the genomes of 2000 essential hypertension cases and 3000 controls using 500 000 genome-wide single nucleotide polymorphisms (SNPs). None of the variants proved to be genome-wide significant after correction for multiple tests but the most significantly associated SNPs (P<10(-5)) constitute a priority list that warrant follow-up in other studies. We describe here replication studies of the top six SNPs in subjects from the US National Heart, Lung, and Blood Institute funded Family Blood Pressure Program comprising 11 433 individuals recruited by hypertensive families. The results suggest that only one of the six SNPs might be associated with essential hypertension in Americans of European origin. This SNP shows a significant but opposite effect in Americans of Hispanic origin and no association in African Americans. The significance of the opposing effect estimates is unclear. No replication could be shown for hypertension status, but there are differences in study design. This attempted replication highlights that essential hypertension studies will require more comprehensive and larger genetic screens.

    orf18 (ac18) of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) is a highly conserved gene in lepidopteran nucleopolyhedroviruses, but its function remains unknown. In this study, an ac18 knockout AcMNPV bacmid was generated to determine the role of ac18 in baculovirus life cycle. After transfection of Sf-9 cells, the ac18-null mutant showed similar infection pattern to the parent virus and the ac18 repair virus with respect to the production of infectious budded virus, occlusion bodies, or the formation of nucleocapsids as visualized by electron microscopy. The deletion mutant did not reduce AcMNPV infectivity for Trichoplusia ni in LD{sub 50} bioassay; however, it did take 24 h longer for deleted mutant to kill T. ni larvae than wild-type virus in LT{sub 50} bioassay. Our results demonstrate that ac18 is not essential for viral propagation both in vitro and in vivo, but it may play a role in efficient virus infection in T. ni larvae.

    Angelica essential oil (AO), a major pharmacologically active component of Angelica sinensis (Oliv.) Diels, possesses hemogenesis, analgesic activities, and sedative effect. The application of AO in pharmaceutical systems had been limited because of its low oxidative stability. The AO-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response surface methodology. The effects of formulation variables (pH at complex coacervation, gelatin concentration, and core/wall ratio) on multiple response variables (yield, encapsulation efficiency, antioxidation rate, percent of drug released in 1 h, and time to 85% drug release) were systemically investigated. A desirability function that combined these five response variables was constructed. All response variables investigated were found to be highly dependent on the formulation variables, with strong interactions observed between the formulation variables. It was found that optimum overall desirability of AO microcapsules could be obtained at pH 6.20, gelatin concentration 25.00%, and core/wall ratio 40.40%. The experimental values of the response variables highly agreed with the predicted values. The antioxidation rate of optimum formulation was approximately 8 times higher than that of AO. The in-vitro drug release from microcapsules was followed Higuchi model with super case-II transport mechanism.

  9. The Essential Role of Epstein-Barr Virus in the Pathogenesis of Multiple Sclerosis

    2011-01-01

    There is increasing evidence that infection with the Epstein-Barr virus (EBV) plays a role in the development of multiple sclerosis (MS), a chronic inflammatory demyelinating disease of the CNS. This article provides a four-tier hypothesis proposing (1) EBV infection is essential for the development of MS; (2) EBV causes MS in genetically susceptible individuals by infecting autoreactive B cells, which seed the CNS where they produce pathogenic autoantibodies and provide costimulatory survival signals to autoreactive T cells that would otherwise die in the CNS by apoptosis; (3) the susceptibility to develop MS after EBV infection is dependent on a genetically determined quantitative deficiency of the cytotoxic CD8+ T cells that normally keep EBV infection under tight control; and (4) sunlight and vitamin D protect against MS by increasing the number of CD8+ T cells available to control EBV infection. The hypothesis makes predictions that can be tested, including the prevention and successful treatment of MS by controlling EBV infection. PMID:21075971

    Autographa californica multiple nucleopolyhedrovirus (AcMNPV) odv-e66 is a core gene and encodes an occlusion-derived virus (ODV)-specific envelope protein, ODV-E66. The N-terminal 23 amino acid of the envelope protein ODV-E66 are sufficient to direct native and fusion proteins to induced membrane microvesicles and the viral envelope during infection with AcMNPV. In this study, an odv-e66-knockout bacmid can not express N-terminal hydrophobic domains was constructed via homologous recombination in Escherichia coli. The odv-e66 deletion had no effect on budded virus (BV) production and viral DNA replication in infected Sf9 cells. Larval bioassays demonstrated that injection of odv-e66 deletion BV into the hemocoel could kill P. xylostella larvae as efficiently as repaired and control viruses; however, odv-e66 deletion mutant resulted in a 50% lethal dose that was 10(3) higher than that of the repaired and control viruses when inoculated per os. These results indicated that ODV-E66 envelope protein most likely played an important role in the oral infectivity of AcMNPV, but is not essential for virus replication.

    Background The continuous exposure to inorganic mercury vapour in artisanal small-scale gold mining (ASGM) areas leads to chronic health problems. It is therefore essential to have a quick, but reliable risk assessing tool to diagnose chronic inorganic mercury intoxication. This study re-evaluates the state-of-the-art toolkit to diagnose chronic inorganic mercury intoxication by analysing data from multiple pooled cross-sectional studies. The primary research question aims to reduce the currently used set of indicators without affecting essentially the capability to diagnose chronic inorganic mercury intoxication. In addition, a sensitivity analysis is performed on established biomonitoring exposure limits for mercury in blood, hair, urine and urine adjusted by creatinine, where the biomonitoring exposure limits are compared to thresholds most associated with chronic inorganic mercury intoxication in artisanal small-scale gold mining. Methods Health data from miners and community members in Indonesia, Tanzania and Zimbabwe were obtained as part of the Global Mercury Project and pooled into one dataset together with their biomarkers mercury in urine, blood and hair. The individual prognostic impact of the indicators on the diagnosis of mercury intoxication is quantified using logistic regression models. The selection is performed by a stepwise forward/backward selection. Different models are compared based on the Bayesian information criterion (BIC) and Cohen`s kappa is used to evaluate the level of agreement between the diagnosis of mercury intoxication based on the currently used set of indicators and the result based on our reduced set of indicators. The sensitivity analysis of biomarker exposure limits of mercury is based on a sequence of chi square tests.

  16. Multiple essential MT1-MMP functions in tooth root formation, dentinogenesis, and tooth eruption

    Membrane-type matrix metalloproteinase 1 (MT1-MMP) is a transmembrane zinc-endopeptidase that breaks down extracellular matrix components, including several collagens, during tissue development and physiological remodeling. MT1-MMP-deficient mice (MT1-MMP−/−) feature severe defects in connective tissues, such as impaired growth, osteopenia, fibrosis, and conspicuous loss of molar tooth eruption and root formation. In order to define the functions of MT1-MMP during root formation and tooth eruption, we analyzed the development of teeth and surrounding tissues in the absence of MT1-MMP. In situ hybridization showed that MT1-MMP was widely expressed in cells associated with teeth and surrounding connective tissues during development. Multiple defects in dentoalveolar tissues were associated with loss of MT1-MMP. Root formation was inhibited by defective structure and function of Hertwig's epithelial root sheath (HERS). However, no defect was found in creation of the eruption pathway, suggesting that tooth eruption was hampered by lack of alveolar bone modeling/remodeling coincident with reduced periodontal ligament (PDL) formation and integration with the alveolar bone. Additionally, we identified a significant defect in dentin formation and mineralization associated with the loss of MT1-MMP. To segregate these multiple defects and trace their cellular origin, conditional ablation of MT1-MMP was performed in epithelia and mesenchyme. Mice featuring selective loss of MT1-MMP activity in the epithelium were indistinguishable from wild type mice, and importantly, featured a normal HERS structure and molar eruption. In contrast, selective knock-out of MT1-MMP in Osterix-expressing mesenchymal cells, including osteoblasts and odontoblasts, recapitulated major defects from the global knock-out including altered HERS structure, short roots, defective dentin formation and mineralization, and reduced alveolar bone formation, although molars were able to erupt.

    aim of the study was to evaluate the presence of the Obsessive Compulsive Personality Disorder (OCPeD) in Multiple System Atrophy (MSA), Progressive Supranuclear Palsy (PSP) and Essential Tremor (ET) and in a group of healthy subjects. patients affected by MSA, PSP and ET diagnosed according to currently accepted diagnostic criteria and a group of healthy controls were enrolled in the study. Patients with cognitive impairment were excluded from the study. The Structured Clinical Interview for Personality Disorders-II (SCID-II) has been performed to evaluate the presence of personality disorders (PeDs). The diagnosis of OCPeD was confirmed by a psychiatric interview. fifteen MSA patients (8 men and 7 women; aged 62.9 ± 7.6 years), 14 PSP patients (8 men and 6 women; aged 69.8 ± 4.4 years), 16 ET patients (10 men and 6 women; aged 70.4 ± 6.4 years) and 20 healthy subjects (10 men and 10 women; aged 65.5 ± 6.0 years) were enrolled. OCPeD was recorded in 5 (35.7%) PSP patients, 2 (13.3%) MSA patients, 2 (12.5%) ET patient and 2 (10%) controls. a low frequency of OCPeD, close to those recorded in healthy subjects, was recorded in both MSA and ET patients. Conversely an higher frequency of OCPeD, similar to PD was found among PSP patients, supporting the possibility of an impairment of common basal ganglia network possibly involving the orbito-frontal circuits.

    When multiple regression is used in explanation-oriented designs, it is very important to determine both the usefulness of the predictor variables and their relative importance. Standardized regression coefficients are routinely provided by commercial programs. However, they generally function rather poorly as indicators of relative importance, especially in the presence of substantially correlated predictors. We provide two user-friendly SPSS programs that implement currently recommended techniques and recent developments for assessing the relevance of the predictors. The programs also allow the user to take into account the effects of measurement error. The first program, MIMR-Corr.sps, uses a correlation matrix as input, whereas the second program, MIMR-Raw.sps, uses the raw data and computes bootstrap confidence intervals of different statistics. The SPSS syntax, a short manual, and data files related to this article are available as supplemental materials from http://brm.psychonomic-journals.org/content/supplemental.

    PK-1 (Ac10) is a baculovirus-encoded serine/threonine kinase and its function is unclear. Our results showed that a pk-1 knockout AcMNPV failed to produce infectious progeny, while the pk-1 repair virus could rescue this defect. qPCR analysis demonstrated that pk-1 deletion did not affect viral DNA replication. Analysis of the repaired recombinants with truncated pk-1 mutants demonstrated that the catalytic domain of protein kinases of PK-1 was essential to viral infectivity. Moreover, those PK-1 mutants that could rescue the infectious BV production defect exhibited kinase activity in vitro. Therefore, it is suggested that the kinase activity of PK-1 is essential in regulating viral propagation. Electron microscopy revealed that pk-1 deletion affected the formation of normal nucleocapsids. Masses of electron-lucent tubular structures were present in cell transfected with pk-1 knockout bacmid. Therefore, PK-1 appears to phosphorylate some viral or cellular proteins that are essential for DNA packaging to regulate nucleocapsid assembly. - Highlights: • A pk-1 knockout AcMNPV failed to produce infectious progeny. • The pk-1 deletion did not affect viral DNA replication. • The catalytic domain of protein kinases (PKc) of PK-1 was essential to viral infectivity. • The kinase activity of PK-1 is essential in regulating viral propagation. • PK-1 appears to phosphorylate some viral proteins that are essential for DNA packaging to regulate nucleocapsid assembly.

    Infections are a significant complication for dialysis patients. The CDC estimates that 37,000 central line-related bloodstream infections occurred in hemodialysis patients in 2008 and dialysis-associated outbreaks of hepatitis C continue to be reported. While established hospital-based infection prevention programs have existed since the 1970s, few dialysis facilities have an established in-center program, unless the dialysis facility is hospital-associated. This review focuses on essential core components required for an effective infection prevention program, extrapolating from acute-care programs and building on current dialysis guidelines and recommendations. An effective infection prevention program requires infrastructure, including leaders who place infection prevention as a top priority, active involvement from a multidisciplinary team, surveillance of outcomes and processes with feedback, staff and patient education, and consistent use of evidence-based practices. The program must be integrated into the existing Quality Assessment and Performance Improvement program. Best practice recommendations for the prevention of infection, specific to dialysis, continue to evolve as the epidemiology of dialysis-associated infections is further researched and new evidence is gathered. A review of case studies illustrates that with an effective program in place, infection prevention becomes part of the culture, reduces infection risk, and improves patient safety. © 2013 Wiley Periodicals, Inc.

    Invariant NKT (iNKT) cells display characteristics of both adaptive and innate lymphoid cells (ILCs). Like other ILCs, iNKT cells constitutively express ID proteins, which antagonize the E protein transcription factors that are essential for adaptive lymphocyte development. However, unlike ILCs, ID2 is not essential for thymic iNKT cell development. In this study, we demonstrated that ID2 and ID3 redundantly promoted iNKT cell lineage specification involving the induction of the signature transcription factor PLZF and that ID3 was critical for development of TBET-dependent NKT1 cells. In contrast, both ID2 and ID3 limited iNKT cell numbers by enforcing the postselection checkpoint in conventional thymocytes. Therefore, iNKT cells show both adaptive and innate-like requirements for ID proteins at distinct checkpoints during iNKT cell development.

    Parkinson's disease and other neurological disorders are prevalent in Mongolia. Our previous studies revealed a significant correlation of these diseases with high oxidative stress due to a high body burden of harmful metals, such as manganese, iron, lead, cadmium, and aluminum. This report describes a 37-year-old male Mongolian patient with multiple sclerosis and essential micronutrient deficiency. This patient demonstrated high oxidative stress, as shown by high urinary 8-hydroxy-2'-deoxyguanosine levels of 14.7 and 14.3 ng/mg creatinine (crea), although his hair levels of these toxic metals were markedly lower than other Mongolians. In addition, this patient was deficient not only in various essential minerals, including selenium, magnesium, copper, cobalt, vanadium, and nickel, but also in micronutrients such as vitamin B6, C, E, folic acid, niacin, and β-carotene. Furthermore, after taking 2,3-dimercaptosuccinic acid, a chelating agent, urinary excretion of lead, cadmium, manganese, aluminum, iron, copper, and lithium were increased 156-, 8.4-, 7.6-, 4.3-, 3.3-, 2.1-, and 2.1-fold, respectively. These results suggest that this patient suffered from a deficiency in micronutrients such as essential minerals and vitamins, which resulted in a disturbance in the ability to excrete harmful metals into the urine and hair. It is possible that a deficiency of micronutrients and a high burden of heavy metals play a role in the pathogenesis of multiple sclerosis. Nutritional treatment may be an effective approach to this disease.

  6. Essential Features of an RET Program: Teachers as Scientists, Scientists as Teachers

    2007-04-01

    Research Experiences for Teachers (RET) programs provide the ultimate professional development opportunity for K-12 educators. Unlike typical workshops or summer institutes, however, they are long term, require a great deal of support from scientists acting as mentors, and are administratively demanding. Designed to provide authentic research experiences, science teachers work with a scientist on a research project that typically ends at the completion of the 6-8 week program. Translating this experience into changes in teacher practice or into classroom materials and experiences is the teacher's responsibility. There are several things to consider when discussing a successful RET program and each of these will be addressed in this talk -- teachers as scientists, scientists as teachers, support for teachers, and support for scientists. Our expectations as mentors and/or program managers are that there will be a measurable difference in how teachers understand the enterprise of science, how students become engaged in science, and how science is taught. The realities of classroom instruction and recent research in how RET programs affect teachers point to a much more subtle result. The challenge, then, is how to move from knowing that RET programs are ``effective'' or ``meaningful experiences'' supported by anecdotal data to showing through empirical evidence that it makes a difference in how teachers approach and teach science. This requires purposeful planning and inclusion of program features that address essential elements of science teaching. This talk focuses on structured activities conducted at the Magnet Lab in Tallahassee, Florida, that help teachers make sense of their experiences while working in diverse laboratories and that help teachers translate that into changes in classroom instruction.

    As a promising data mining tool, Multiple Criteria Linear Programming (MCLP) has been widely used in business intelligence. However, a possible limitation of MCLP is that it generates unexplainable black-box models which can only tell us results without reasons. To overcome this shortage, in this paper, we propose a Knowledge Mining strategy which mines from black-box MCLP models to get explainable and understandable knowledge. Different from the traditional Data Mining strategy which focuses on mining knowledge from data, this Knowledge Mining strategy provides a new vision of mining knowledge from black-box models, which can be taken as a special topic of “Intelligent Knowledge Management”.

    This paper presents an ADBASE-based parallel algorithm for solving multiple objective linear programs (MOLP's). Job balance, speedup and scalability are of primary interest in evaluating efficiency of the new algorithm. Implementation results on Intel iPSC/2 and Paragon multiprocessors show that the algorithm significantly speeds up the process of solving MOLP's, which is understood as generating all or some efficient extreme points and unbounded efficient edges. The algorithm gives specially good results for large and very large problems. Motivation and justification for solving such large MOLP's are also included.

    We describe a system that allows programmers to take advantage of both control and data parallelism through multiple intercommunicating data-parallel modules. This programming environment extends C-type stream I/O to include intermodule communication channels. The progammer writes each module as a separate data-parallel program, then develops a channel linker specification describing how to connect the modules together. A channel linker we have developed loads the separate modules on the parallel machine and binds the communication channels together as specified. We present performance data that demonstrates a mixed control- and data-parallel solution can yield better performance than a strictly data-parallel solution. The system described currently runs on the Intel iWarp multicomputer.

    Feature extration from imagery is an important and long-standing problem in remote sensing. In this paper, we report on work using genetic programming to perform feature extraction simultaneously from multispectral and digital elevation model (DEM) data. The tool used is the GENetic Imagery Exploitation (GENIE) software, which produces image-processing software that inherently combines spatial and spectral processing. GENIE is particularly useful in exploratory studies of imagery, such as one often does in combining data from multiple sources. The user trains the software by painting the feature of interest with a simple graphical user interface. GENIE then uses genetic programming techniques to produce an image-processing pipeline. Here, we demonstrate evolution of image processing algorithms that extract a range of land-cover features including towns, grasslands, wild fire burn scars, and several types of forest. We use imagery from the DOE/NNSA Multispectral Thermal Imager (MTI) spacecraft, fused with USGS 1:24000 scale DEM data.

  11. JED: a Java Essential Dynamics Program for comparative analysis of protein trajectories.

    Essential Dynamics (ED) is a common application of principal component analysis (PCA) to extract biologically relevant motions from atomic trajectories of proteins. Covariance and correlation based PCA are two common approaches to determine PCA modes (eigenvectors) and their eigenvalues. Protein dynamics can be characterized in terms of Cartesian coordinates or internal distance pairs. In understanding protein dynamics, a comparison of trajectories taken from a set of proteins for similarity assessment provides insight into conserved mechanisms. Comprehensive software is needed to facilitate comparative-analysis with user-friendly features that are rooted in best practices from multivariate statistics. We developed a Java based Essential Dynamics toolkit called JED to compare the ED from multiple protein trajectories. Trajectories from different simulations and different proteins can be pooled for comparative studies. JED implements Cartesian-based coordinates (cPCA) and internal distance pair coordinates (dpPCA) as options to construct covariance (Q) or correlation (R) matrices. Statistical methods are implemented for treating outliers, benchmarking sampling adequacy, characterizing the precision of Q and R, and reporting partial correlations. JED output results as text files that include transformed coordinates for aligned structures, several metrics that quantify protein mobility, PCA modes with their eigenvalues, and displacement vector (DV) projections onto the top principal modes.

    Adherence to medication and lifestyle interventions are essential keys for the management of hypertension. In this respect, a structured educational program for hypertensive patients has got remarkable merits (herz.leben). In order to determine the isolated effect of participation in the educational program, neglecting the possible impact of more intense care, this prospective multicenter randomized controlled study was designed (NCT00453037). A total of 256 patients in 13 centers were enrolled and randomly assigned to 2 groups (G). G-I (n = 137) underwent the educational program immediately (T-0), G-II (n = 119) after 6 months (T-6). Follow-up visits were done after 6 (T-6) and 12 (T-12) months. Primary endpoint was a difference in office blood pressure (BP) at T-6, when only G-I had undergone the educational program. Patients' baseline characteristics were comparable. At T-6, systolic office and home BP were significantly lower in G-I compared to G-II: office BP systolic 139 (134-150) mm Hg vs. 150 (135-165) mm Hg (P < 0.01); diastolic 80 (76-85) mm Hg vs. 84 (75-90) mm Hg (ns); home BP systolic 133 (130-140) mm Hg vs. 142 (132-150) mm Hg (P < 0.01); diastolic 80 (75-85) mm Hg vs. 80 (76-89) mm Hg (ns)). At T-12, when all patients had undergone the educational program differences in BP disappeared. The results of this multicenter randomized controlled study provide significant evidence for benefit by participation in a structured educational program. Positive effects seem to be mediated by better adherence and life style changes due to higher levels of information and patient empowerment. Therefore, educational strategies should be considered as standard of care for hypertensive patients. © American Journal of Hypertension, Ltd 2015. All rights reserved.

    CTLs are serial killers that kill multiple target cells via exocytosis of cytotoxic granules (CGs). CG exocytosis is tightly regulated and has been investigated in great detail; however, whether CG proteins are endocytosed following exocytosis and contribute to serial killing remains unknown. By using primary CTLs derived from a knock-in mouse of the CG membrane protein Synaptobrevin2, we show that CGs are endocytosed in a clathrin- and dynamin-dependent manner. Following acidification, endocytosed CGs are recycled through early and late, but not recycling endosomes. CGs are refilled with granzyme B at the late endosome stage and polarize to subsequent synapses formed between the CTL and new target cells. Importantly, inhibiting CG endocytosis in CTLs results in a significant reduction of their cytotoxic activity. Thus, our data demonstrate that continuous endocytosis of CG membrane proteins is a prerequisite for efficient serial killing of CTLs and identify key events in this process.

    Operating room (OR) safety has become a major concern in patient safety since the 1990s. Improvement of team communication and behavior is a popular target for safety programming at the institutional level. Despite these efforts, essential safety gaps remain in the OR and procedure rooms. A prime example is the use of energy-based devices in ORs and procedural areas. The lack of fundamental understanding of energy device function, design, and application contributes to avoidable injury and harm at a rate of approximately 1 to 2 per 1000 patients in the US. Hundreds of OR fires occur each year in the US, some causing severe injury and even death. Most of these fires are associated with the use of energy-based surgical devices.In response to this safety issue, the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) developed the Fundamental Use of Surgical Energy (FUSE) program. This program includes a standardized curriculum targeted to surgeons, other physicians, and allied health care professionals and a psychometrically designed and validated certification test. A successful FUSE certification documents acquisition of the basic knowledge needed to safely use energy-based devices in the OR. By design FUSE fills a void in the curriculum and competency assessment for surgeons and other procedural specialists in the use of energy-based devices in patients.

    Neuronal activity influences genes involved in circuit development and information processing. However, the molecular basis of this process remains poorly understood. We found that HDAC4, a histone deacetylase that shuttles between the nucleus and cytoplasm, controls a transcriptional program essential for synaptic plasticity and memory. The nuclear import of HDAC4 and its association with chromatin is negatively regulated by NMDA receptors. In the nucleus, HDAC4 represses genes encoding constituents of central synapses, thereby affecting synaptic architecture and strength. Furthermore, we show that a truncated form of HDAC4 encoded by an allele associated with mental retardation is a gain-of-function nuclear repressor that abolishes transcription and synaptic transmission despite the loss of the deacetylase domain. Accordingly, mice carrying a mutant that mimics this allele exhibit deficits in neurotransmission, spatial learning, and memory. These studies elucidate a mechanism of experience-dependent plasticity and define the biological role of HDAC4 in the brain.

    Background: With the recent spread of virtual learning programs in universities, especially in the field of medical sciences, libraries play a crucial role to support these programs. This study aimed at investigating the skills required by librarians to support virtual learning programs in Isfahan University and Isfahan University of Medical Sciences. Methods: This was an applied survey study. The population of the study includes all librarians working in Isfahan University and Isfahan University of Medical Sciences. A sample of 89 librarians was selected by stratified random sampling. Data were collected by a researcher-made questionnaire, the validity of which was confirmed by specialists in the fields of librarianship and information sciences and virtual learning, and its reliability was determined to be 0.92, using Cronbach's Alpha. The questionnaire consisted of 51 items designed to evaluate the librarians' virtual learning skills using Likert scale. Descriptive and inferential statistics were used to analyze the findings. Results: The findings of this study revealed that librarians had low level of skills with respect to the online reference services, and familiarity with virtual learning environment. They also showed low and average level of skills with respect to their general information technology, communication skills, ability to teach electronic information literacy and ability to create access to electronic resources. The results revealed no significant difference between the librarians of the two universities, or between male and female librarians. However, librarians with educational background in librarianship and information sciences were significantly more skillful and competent than their colleagues. Conclusion: Despite the crucial role of libraries in supporting virtual learning programs, the librarians in Isfahan University and Isfahan University of Medical Sciences had low-level skills to play such an important role. Therefore, it is essential

    The F-15 Air Navigation Multiple Indicator (ANMI) is the vertical situation display in the F-15A/B and C/D aircraft. The Air Force established the ANMI Prototype Development Program as a form, fit and function replacement for the existing Cathode Ray Tube (CRT) display. Oklahoma City Air Logistics Center (OC-ALC) is the lead agency for the development with financial support from the Producibility, Reliability and Maintainability (PRAM) Program Office at Wright-Patterson. SAIC was selected to design the prototype unit. Figure 1 is an exploded view of this prototype. The F-15 ANMI development required SAIC to address many new challenges. Four unique technical challenges were: (1) the development of a high resolution liquid crystal display (LCD), (2) the interface with an analog signal used to drive the existing CRT, (3) the development of a NTSC output, and (4) the sunlight readable, Night Vision Goggle compatible backlight. These technical aspects of the development are detailed in the body of this paper.

    Phytochrome A is the primary photoreceptor for mediating various far-red light-induced responses in higher plants. We recently showed that Arabidopsis (Arabidopsis thaliana) FAR-RED ELONGATED HYPOCOTYL3 (FHY3) and FAR-RED-IMPAIRED RESPONSE1 (FAR1), a pair of homologous proteins sharing significant sequence homology to Mutator-like transposases, act as novel transcription factors essential for activating the expression of FHY1 and FHL (for FHY1-like), whose products are required for light-induced phytochrome A nuclear accumulation and subsequent light responses. FHY3, FAR1, and Mutator-like transposases also share a similar domain structure, including an N-terminal C2H2 zinc finger domain, a central putative core transposase domain, and a C-terminal SWIM motif (named after SWI2/SNF and MuDR transposases). In this study, we performed a promoter-swapping analysis of FHY3 and FAR1. Our results suggest that the partially overlapping functions of FHY3 and FAR1 entail divergence of their promoter activities and protein subfunctionalization. To gain a better understanding of the molecular mode of FHY3 function, we performed a structure-function analysis, using site-directed mutagenesis and transgenic approaches. We show that the conserved N-terminal C2H2 zinc finger domain is essential for direct DNA binding and biological function of FHY3 in mediating light signaling, whereas the central core transposase domain and C-terminal SWIM domain are essential for the transcriptional regulatory activity of FHY3 and its homodimerization or heterodimerization with FAR1. Furthermore, the ability to form homodimers or heterodimers largely correlates with the transcriptional regulatory activity of FHY3 in plant cells. Together, our results reveal discrete roles of the multiple domains of FHY3 and provide functional support for the proposition that FHY3 and FAR1 represent transcription factors derived from a Mutator-like transposase(s).

    As of October 2016, use of federal Older Americans Act funds for health promotion and disease prevention will be restricted to the Administration on Aging's criteria for high-level evidence-based health promotion programs. Dissemination of these programs to rural communities remains limited. Therefore a strong need exists to identify strategies that facilitate program implementation and sustainability. The objective of this study was to compare organizational readiness and implementation strategies used by rural communities that achieved varying levels of success in sustaining evidence-based health promotion programs for older adults. We utilized a qualitative multi-site case study design to analyze the longitudinal experiences of eight rural sites working to implement evidence-based health promotion program over 3 years (8/2012-7/2015). Multiple sources of data (interviews, documents, reports, surveys) from each site informed the analysis. We used conventional content analysis to conduct a cross-case comparison to identify common features of rural counties that successfully implemented and sustained their target evidence-based health promotion program. Readiness to implement evidence-based programs as low at baseline as all site leaders described needing to secure additional resources for program implementation. Sites that successfully utilized six essential resources implemented and sustained greater numbers of workshops: (1) External Partnerships, (2) Agency Leadership Commitment, (3) Ongoing Source of Workshop Leaders, (4) Health Promotion Coordination Tasks Assigned to Specific Staff, (5) Organizational Stability, and (6) Change Team Engagement. The six essential resources described in this study can help rural communities assess their readiness to implement health promotion programs and work secure the resources necessary for successful implementation.

    Essential thrombocytosis is a myeloproliferative disorder of unknown etiology manifested clinically by the overproduction of platelets in the absence of a definable cause. Platelet dysfunction in essential thrombocytosis results in both hemorrhage and thrombosis. It is one of the rare causes of ischemic cardiovascular events. Fewer than 20 cases of essential thrombocytosis with involvement of coronary arteries leading to acute coronary syndromes or myocardial infarction have been reported. We report a case of multiple coronary thrombosis involving the left anterior descending artery and circumflex artery and stent implantation to the subtotally stenotic right renal artery in a women with unstable angina pectoris, essential thrombocytosis and previous history of renal artery trombosis.

    Baculoviridae is a family of insect-specific viruses that have a circular double-stranded DNA genome packaged within a rod-shaped capsid. The mechanism of baculovirus nucleocapsid assembly remains unclear. Previous studies have shown that deletion of the ac83 gene of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) blocks viral nucleocapsid assembly. Interestingly, the ac83-encoded protein Ac83 is not a component of the nucleocapsid, implying a particular role for ac83 in nucleocapsid assembly that may be independent of its protein product. To examine this possibility, Ac83 synthesis was disrupted by insertion of a chloramphenicol resistance gene into its coding sequence or by deleting its promoter and translation start codon. Both mutants produced progeny viruses normally, indicating that the Ac83 protein is not required for nucleocapsid assembly. Subsequently, complementation assays showed that the production of progeny viruses required the presence of ac83 in the AcMNPV genome instead of its presence in trans Therefore, we reasoned that ac83 is involved in nucleocapsid assembly via an internal cis-acting element, which we named the nucleocapsid assembly-essential element (NAE). The NAE was identified to lie within nucleotides 1651 to 1850 of ac83 and had 8 conserved A/T-rich regions. Sequences homologous to the NAE were found only in alphabaculoviruses and have a conserved positional relationship with another essential cis-acting element that was recently identified. The identification of the NAE may help to connect the data of viral cis-acting elements and related proteins in the baculovirus nucleocapsid assembly, which is important for elucidating DNA-protein interaction events during this process.IMPORTANCE Virus nucleocapsid assembly usually requires specific cis-acting elements in the viral genome for various processes, such as the selection of the viral genome from the cellular nucleic acids, the cleavage of concatemeric viral genome

  11. Is a hypothetical melanoma-like neuromelanin the underlying factor essential for the aetiopathogenesis and clinical manifestations of multiple sclerosis?

    PubMed Central

    2013-01-01

    Background Multiple sclerosis (MS) has undergone a significant increase in incidence in the industrialised nations over the last 130 years. Changing environmental factors, possibly infections or a lack of or altered timing of them, determine the prevalence of the disease. Although a plethora of aetiological factors, clearly evident in a group of children with MS, appear relevant, there may nevertheless be a single factor essential for the aetiopathogenesis and clinical manifestation of MS. Description and discussion This hitherto unknown factor is postulated to be a ‘melanoma-like neuromelanin’ (MLN) dependent on the activation of a gene for syncytin-1. An involvement of MLN could explain the diverse findings in the epidemiology, immunology and pathology of MS, requiring a consideration of a complex infectious background, the human leucocyte antigens, as well as cosmic radiation causing geomagnetic disturbances, vitamin D deficiency, smoking, and lower levels of uric acid. Summary In principle, the MLN-based concept is a unifying one, capable of explaining a number of characteristics of the disease. To date, MLN has not been addressed in studies on MS and future work will need to be done on human patients, as there is little or no neuromelanin (the precursor of MLN) in the animals used as experimental models in the study of MS.

    The docking protein FRS2alpha is a major mediator of fibroblast growth factor (FGF) signaling. However, the physiological role of FRS2alpha in vivo remains unknown. In this report, we show that Frs2alpha-null mouse embryos have a defect in anterior-posterior (A-P) axis formation and are developmentally retarded, resulting in embryonic lethality by embryonic day 8. We demonstrate that FRS2alpha is essential for the maintenance of self-renewing trophoblast stem (TS) cells in response to FGF4 in the extraembryonic ectoderm (ExE) that gives rise to tissues of the placenta. By analyzing chimeric embryos, we found that FRS2alpha also plays a role in cell movement through the primitive streak during gastrulation. In addition, experiments are presented demonstrating that Bmp4 expression in TS cells is controlled by mitogen-activated protein kinase-dependent FGF4 stimulation. Moreover, both the expression of Bmp4 in ExE and activation of Smad1/5 in epiblasts are reduced in Frs2alpha-null embryos. These experiments underscore the critical role of FRS2alpha in mediating multiple processes during embryonic development and reveal a potential new link between FGF and Bmp4 signaling pathways in early embryogenesis.

    2010-09-01

    It is essential for nurses to develop critical thinking skills to ensure their ability to provide safe and effective care to patients with complex and variable needs in ever-changing clinical environments. To date, very few studies have been conducted to examine how nursing orientation programs develop the critical thinking skills of novice critical care nurses. Strikingly, no research studies could be found about the American Association of Critical Care Nurses Essentials of Critical Care Orientation (ECCO) program and specifically its effect on the development of nurses' critical thinking skills. This study explored the perceptions of new graduate nurses regarding factors that helped to develop their critical thinking skills throughout their 6-month orientation program in the intensive care unit. A convenient non-probability sample of eight new graduates was selected from a hospital that used the ECCO program. Data were collected with demographic questionnaires and semi-structured interviews. An exploratory qualitative research method with content analysis was used to analyze the data. The study findings showed that new graduate nurses perceived that they developed critical thinking skills that improved throughout the orientation period, although there were some challenges in the ECCO program. This study provides data that could influence the development and implementation of future nursing orientation programs.

    2012-12-01

    Newborn screening for critical congenital heart defects, added in September 2011 to the Recommended Uniform Screening Panel in the United States, is a new public health priority and has particular relevance for state birth defects surveillance programs. In this commentary, we review the background to potential involvement by birth defects programs with screening, and detail key questions that these programs can evaluate: (1) health outcomes after newborn screening among affected children; (2) missed primary targets of screening (i.e., affected children who were not screened or had false-negative screens); (3) burden and screening accuracy for secondary targets; (4) the role of altitude, sociodemographic characteristics, and other special circumstances; (5) the contribution of prenatal and clinical diagnoses before newborn screening; and (6) costs and service utilization. To address these issues, monitoring programs will need to pay particular attention to: (1) data sources and quality; (2) timeliness; (3) long-term follow-up for comprehensive outcomes; (4) reporting standards; and (5) state and national program coordination. Although some aspects of involvement with these screening programs will require new partnerships and paradigm shifts in birth defects program operations, the visibility of these screening programs among stakeholders will also provide birth defects programs with new opportunities to demonstrate their usefulness.

    Bursch, Wilfried

    2004-11-01

    Cells use different pathways for active self-destruction as reflected by different morphology: while in apoptosis (or "type I") nuclear fragmentation associated with cytoplasmic condensation but preservation of organelles is predominant, autophagic degradation of cytoplasmic structures preceding nuclear collapse is a characteristic of a second type of programmed cell death (PCD). The diverse morphologies can be attributed--at least to some extent--to distinct biochemical and molecular events (e.g. caspase-dependent and -independent death programs; DAP-kinase activity, Ras-expression). However, apoptosis and autophagic PCD are not mutually exclusive phenomena. Rather, diverse PCD programs emerged during evolution, the conservation of which apparently allows cells a flexible response to environmental changes, either physiological or pathological.

    With the conclusion of the shuttle program in 2011, the National Aeronautics and Space Administration (NASA) had found itself at a crossroads for finding transportation of United States astronauts and experiments to space. The agency would eventually hand off the taxiing of American astronauts to the International Space Station (ISS) that orbits in Low Earth Orbit (LEO) about 210 miles above the earth under the requirements of the Commercial Crew Program (CCP). By privatizing the round trip journey from Earth to the ISS, the space agency has been given the additional time to focus funding and resources to projects that operate beyond LEO; however, adding even more stress to the agency, the premature cancellation of the program that would succeed the Shuttle Program - The Constellation Program (CxP) -it would inevitably delay the goal to travel beyond LEO for a number of years. Enter the Space Launch System (SLS) and the Orion Multipurpose Crew Vehicle (MPCV). Currently, the SLS is under development at NASA's Marshall Spaceflight Center in Huntsville, Alabama, while the Orion Capsule, built by government contractor Lockheed Martin Corporation, has been assembled and is currently under testing at the Kennedy Space Center (KSC) in Florida. In its current vision, SLS will take Orion and its crew to an asteroid that had been captured in an earlier mission in lunar orbit. Additionally, this vehicle and its configuration is NASA's transportation to Mars. Engineers at the Kennedy Space Center are currently working to test the ground systems that will facilitate the launch of Orion and the SLS within its Ground Services Development and Operations (GSDO) Program. Firing Room 1 in the Launch Control Center (LCC) has been refurbished and outfitted to support the SLS Program. In addition, the Spaceport Command and Control System (SCCS) is the underlying control system for monitoring and launching manned launch vehicles. As NASA finds itself at a junction, so does all of its

    A critical feature of neural networks is that they balance excitation and inhibition to prevent pathological dysfunction. How this is achieved is largely unknown, although deficits in the balance contribute to many neurological disorders. We show here that a microRNA (miR-101) is a key orchestrator of this essential feature, shaping the developing network to constrain excitation in the adult. Transient early blockade of miR-101 induces long-lasting hyper-excitability and persistent memory deficits. Using target site blockers in vivo, we identify multiple developmental programs regulated in parallel by miR-101 to achieve balanced networks. Repression of one target, NKCC1, initiates the switch in γ-aminobutyric acid (GABA) signaling, limits early spontaneous activity, and constrains dendritic growth. Kif1a and Ank2 are targeted to prevent excessive synapse formation. Simultaneous de-repression of these three targets completely phenocopies major dysfunctions produced by miR-101 blockade. Our results provide new mechanistic insight into brain development and suggest novel candidates for therapeutic intervention.

    Tissue- and cell-type-specific regulators of alternative splicing (AS) are essential components of posttranscriptional gene regulation, necessary for normal cellular function, patterning, and development. Mice with ablation of Epithelial splicing regulatory protein (Esrp1) develop cleft lip and palate. Loss of both Esrp1 and its paralog Esrp2 results in widespread developmental defects with broad implications to human disease. Deletion of the Esrps in the epidermis revealed their requirement for establishing a proper skin barrier, a primary function of epithelial cells comprising the epidermis. We profiled the global Esrp-mediated splicing regulatory program in epidermis, which revealed large-scale programs of epithelial cell-type-specific splicing required for epithelial cell functions. These mice represent a valuable model for evaluating the essential role for AS in development and function of epithelial cells, which play essential roles in tissue homeostasis in numerous organs, and provide a genetic tool to evaluate important functional properties of epithelial-specific splice variants in vivo.

  1. Motor programming when sequencing multiple elements of the same duration.

    PubMed

    Magnuson, Curt E; Robin, Donald A; Wright, David L

    2008-11-01

    Motor programming at the self-select paradigm was adopted in 2 experiments to examine the processing demands of independent processes. One process (INT) is responsible for organizing the internal features of the individual elements in a movement (e.g., response duration). The 2nd process (SEQ) is responsible for placing the elements into the proper serial order before execution. Participants in Experiment 1 performed tasks involving 1 key press or sequences of 4 key presses of the same duration. Implementing INT and SEQ was more time consuming for key-pressing sequences than for single key-press tasks. Experiment 2 examined whether the INT costs resulting from the increase in sequence length observed in Experiment 1 resulted from independent planning of each sequence element or via a separate "multiplier" process that handled repetitions of elements of the same duration. Findings from Experiment 2, in which participants performed single key presses or double or triple key sequences of the same duration, suggested that INT is involved with the independent organization of each element contained in the sequence. Researchers offer an elaboration of the 2-process account of motor programming to incorporate the present findings and the findings from other recent sequence-learning research.

    Hereditary multiple exostoses an autosomal dominant skeletal disorder characterized by multiple cartilage-capped benign exostoses that typically occur in the metaphysis of long bones. The prevalence of hereditary multiple exostoses is estimated to be 1 in 50,000. Although, there have been many studies concerning this rare disorder, no research has yet examined the rehabilitation of hereditary multiple exostoses. The case diagnosed with hereditary multiple exostoses referred to our department with several complaints, namely pain, joint limitations, muscle weakness, and functional insufficiency after arthroscopic distal left femur exostoses excision. The aim of this case report was to present effectiveness of eccentric training as an adjunct to rehabilitation program for hereditary multiple exostoses. According to the results, eccentric training after arthroscopic exostoses excision may help reduce pain, increase range of motion, muscle strength, and functional levels in patients with hereditary multiple exostoses.

    2012-01-01

    Mucin-type O-glycosylation represents a major form of post-translational modification that is conserved across most eukaryotic species. This type of glycosylation is initiated by a family of enzymes (GalNAc-Ts in mammals and PGANTs in Drosophila) whose members are expressed in distinct spatial and temporal patterns during development. Previous work from our group demonstrated that one member of this family is essential for viability and another member modulates extracellular matrix composition and integrin-mediated cell adhesion during development. To investigate whether other members of this family are essential, we employed RNA interference (RNAi) to each gene in vivo. Using this approach, we identified 4 additional pgant genes that are required for viability. Ubiquitous RNAi to pgant4, pgant5, pgant7, or the putative glycosyltransferase CG30463 resulted in lethality. Tissue-specific RNAi was also used to define the specific organ systems and tissues in which each essential family member is required. Interestingly, each essential pgant had a unique complement of tissues in which it was required. Additionally, certain tissues (mesoderm, digestive system, and tracheal system) required more than one pgant, suggesting unique functions for specific enzymes in these tissues. Expanding upon our RNAi results, we found that conventional mutations in pgant5 resulted in lethality and specific defects in specialized cells of the digestive tract, resulting in loss of proper digestive system acidification. In summary, our results highlight essential roles for O-glycosylation and specific members of the pgant family in many aspects of development and organogenesis. PMID:22157008

  17. Innate IFN-γ is essential for Programmed death ligand-1-mediated T cell stimulation following Listeria monocytogenes infection

    Rowe, Jared H.; Ertelt, James M.; Way, Sing Sing

    2012-01-01

    Although best characterized for sustaining T cell exhaustion during persistent viral infection, Programmed death ligand (PDL)-1 also stimulates the expansion of protective T cells after infection with intracellular bacterial pathogens. Therefore, establishing the molecular signals that control whether PDL-1 stimulates immune suppression or activation is important as immune modulation therapies based on manipulating PDL-1 are being developed. Herein, the requirement for PDL-1 blockade initiated before infection with the intracellular bacterium Listeria monocytogenes (Lm) in reducing pathogen-specific T cell expansion is demonstrated. In turn, the role of proinflammatory cytokines triggered early after Lm infection in controlling PDL-1-mediated T cell stimulation was investigated using mice with targeted defects in specific cytokines or cytokine receptors. These experiments illustrate an essential role for IL-12 or type I IFNs in PDL-1-mediated expansion of pathogen-specific CD8+ T cells. Unexpectedly, direct stimulation by neither IL-12 nor type I IFNs on pathogen-specific CD8+ cells was essential for PDL-1-mediated expansion. Instead, the absence of early innate IFN-γ production in mice with combined defects in both IL-12 and type I IFN receptor negated the impacts of PDL-1 blockade. In turn, IFN-γ ablation using neutralizing antibodies or in mice with targeted defects in IFN-γ receptor each eliminated the PDL-1-mediated stimulatory impacts on pathogen-specific T cell expansion. Thus, innate IFN-γ is essential for PDL-1-mediated T cell stimulation. PMID:22711893

    Integrative medicine (IM) refers to the combination of conventional and "complementary" medical services (e.g., chiropractic, acupuncture, massage, mindfulness training). More than half of all medical schools in the United States and Canada have programs in IM, and more than 30 academic health centers currently deliver multidisciplinary IM care. What remains unclear, however, is the ideal delivery model (or models) whereby individuals can responsibly access IM care safely, effectively, and reproducibly in a coordinated and cost-effective way.Current models of IM across existing clinical centers vary tremendously in their organizational settings, principal clinical focus, and services provided; practitioner team composition and training; incorporation of research activities and educational programs; and administrative organization (e.g., reporting structure, use of medical records, scope of clinical practice) and financial strategies (i.e., specific business plans and models for sustainability).In this article, the authors address these important strategic issues by sharing lessons learned from the design and implementation of an IM facility within an academic teaching hospital, the Brigham and Women's Hospital at Harvard Medical School; and review alternative options based on information about IM centers across the United States.The authors conclude that there is currently no consensus as to how integrative care models should be optimally organized, implemented, replicated, assessed, and funded. The time may be right for prospective research in "best practices" across emerging models of IM care nationally in an effort to standardize, refine, and replicate them in preparation for rigorous cost-effectiveness evaluations.

    Spermatozoa are flagellated cells whose role in fertilization is dependent on their ability to move towards an oocyte. The structure of the sperm flagella is highly conserved across species, and much of what is known about this structure is derived from studies utilizing animal models. One group of proteins essential for the movement of the flagella are the dyneins. Using the advanced technology of CRISPR/Cas9 we have targeted three dynein group members; Dnaic1, Wdr63 and Ccdc63 in mice. All three of these genes are expressed strongly in the testis. We generated mice with amino acid substitutions in Dnaic1 to analyze two specific phosphorylation events at S124 and S127, and generated simple knockouts of Wdr63 and Ccdc63. We found that the targeted phosphorylation sites in Dnaic1 were not essential for male fertility. Similarly, Wdr63 was not essential for male fertility; however, Ccdc63 removal resulted in sterile male mice due to shortened flagella. This study demonstrates the versatility of the CRISPR/Cas9 system to generate animal models of a highly complex system by introducing point mutations and simple knockouts in a fast and efficient manner.

  1. Endosymbiosis in trypanosomatids: the genomic cooperation between bacterium and host in the synthesis of essential amino acids is heavily influenced by multiple horizontal gene transfers

    PubMed Central

    2013-01-01

    Background Trypanosomatids of the genera Angomonas and Strigomonas live in a mutualistic association characterized by extensive metabolic cooperation with obligate endosymbiotic Betaproteobacteria. However, the role played by the symbiont has been more guessed by indirect means than evidenced. Symbiont-harboring trypanosomatids, in contrast to their counterparts lacking symbionts, exhibit lower nutritional requirements and are autotrophic for essential amino acids. To evidence the symbiont’s contributions to this autotrophy, entire genomes of symbionts and trypanosomatids with and without symbionts were sequenced here. Results Analyses of the essential amino acid pathways revealed that most biosynthetic routes are in the symbiont genome. By contrast, the host trypanosomatid genome contains fewer genes, about half of which originated from different bacterial groups, perhaps only one of which (ornithine cyclodeaminase, EC:4.3.1.12) derived from the symbiont. Nutritional, enzymatic, and genomic data were jointly analyzed to construct an integrated view of essential amino acid metabolism in symbiont-harboring trypanosomatids. This comprehensive analysis showed perfect concordance among all these data, and revealed that the symbiont contains genes for enzymes that complete essential biosynthetic routes for the host amino acid production, thus explaining the low requirement for these elements in symbiont-harboring trypanosomatids. Phylogenetic analyses show that the cooperation between symbionts and their hosts is complemented by multiple horizontal gene transfers, from bacterial lineages to trypanosomatids, that occurred several times in the course of their evolution. Transfers occur preferentially in parts of the pathways that are missing from other eukaryotes. Conclusion We have herein uncovered the genetic and evolutionary bases of essential amino acid biosynthesis in several trypanosomatids with and without endosymbionts, explaining and complementing decades of

    High prevalence of poverty diseases such as diarrhoea, respiratory tract infection, parasitic infections and dental caries among children in the developing world calls for a return to primary health care principles with a focus on prevention. The 'Fit for School' program in the Philippines is based on international recommendations and offers a feasible, low-cost and realistic strategy using the principles of health promotion outlined in the Ottawa Charter. The cornerstone of the programme is the use of school structures for the implementation of preventive health strategies. 'Fit for School' consists of simple, evidence-based interventions like hand washing with soap, tooth brushing with fluoride toothpaste and other high impact interventions such as bi-annual de-worming as a routine school activity for all children visiting public elementary schools. The programme has been successfully rolled-out in the Philippines covering 630,000 children in 22 provinces and it is planned to reach 6 million children in the next three years. The programme is a partnership project between the Philippine Department of Education and the Local Government Units with support for capacity development activities from the German Development Cooperation and GlaxoSmithKline.

    Irregularities in the cellular uptake of thyroid hormones significantly affect muscle development and regeneration. Herein, we report indispensable role of transthyretin (TTR) in maintaining cellular thyroxine level. TTR was found to enhance recruitment of muscle satellite cells to the site of injury, thereby regulating muscle regeneration. Fluorescence-activated cell sorting (FACS) and immunofluorescence analysis of TTRwt (TTR wild type) and TTRkd (TTR knock-down) cells revealed that TTR controlled cell cycle progression by affecting the expression of Cyclin A2. Deiodinase 2 (D2) mediated increases in triiodothyronine levels were found to regulate the expression of myogenic marker, myogenin (MYOG). Moreover, use of a coumarin derivative (CD) revealed a significant reduction in cellular thyroxine, thereby indicating that TTR play a role in the transport of thyroxine. Taken together, these findings suggest that TTR mediated transport of thyroxine represents a survival mechanism necessary for the myogenic program. The results of this study will be highly useful to the strategic development of novel therapeutics to combat muscular dystrophies. PMID:28075349

    Tumour-initiating cells (TICs) are advocated to constitute the sustaining force to maintain and renew fully established malignancy; however, the molecular mechanisms responsible for these properties are elusive. We previously demonstrated that voltage-gated calcium channel α2δ1 subunit marks hepatocellular carcinoma (HCC) TICs. Here we confirm directly that α2δ1 is a HCC TIC surface marker, and identify let-7c, miR-200b, miR-222 and miR-424 as suppressors of α2δ1(+) HCC TICs. Interestingly, all the four miRNAs synergistically target PBX3, which is sufficient and necessary for the acquisition and maintenance of TIC properties. Moreover, PBX3 drives an essential transcriptional programme, activating the expression of genes critical for HCC TIC stemness including CACNA2D1, EpCAM, SOX2 and NOTCH3. In addition, the expression of CACNA2D1 and PBX3 mRNA is predictive of poor prognosis for HCC patients. Collectively, our study identifies an essential signalling pathway that controls the switch of HCC TIC phenotypes.

    Metabolic programming occurs when variations in nutrition during a specific developmental window result in long-term metabolic effects. It has been studied almost exclusively in humans and other mammals but never in an ecological context. Here, we report metabolic programming and its functional consequences in a marine fish, red drum. We demonstrate that maternal provisioning of eggs with an essential fatty acid, docosahexaenoic acid (DHA), varies with DHA content of the maternal diet. When offspring are reared on a DHA-replete diet, whole-body DHA content of offspring depends upon the amount of DHA that was in the egg. We further demonstrate that whole-body DHA content is correlated with traits related to offspring fitness (escape responses, routine swimming, growth, and survival). DHA content of red drum eggs produced in nature is in the range where the effects of metabolic programming are most pronounced. Our findings indicate that during a brief developmental window, DHA plays a role in establishing the metabolic capacity for its own uptake or storage, with protracted and possibly permanent effects on ecologically important survival skills of individuals and important implications for dynamics of populations and food webs.

  8. A jack of all trades: the multiple roles of the unique essential second messenger cyclic di-AMP.

    Second messengers are key components of many signal transduction pathways. In addition to cyclic AMP, ppGpp and cyclic di-GMP, many bacteria use also cyclic di-AMP as a second messenger. This molecule is synthesized by distinct classes of diadenylate cyclases and degraded by phosphodiesterases. The control of the intracellular c-di-AMP pool is very important since both a lack of this molecule and its accumulation can inhibit growth of the bacteria. In many firmicutes, c-di-AMP is essential, making it the only known essential second messenger. Cyclic di-AMP is implicated in a variety of functions in the cell, including cell wall metabolism, potassium homeostasis, DNA repair and the control of gene expression. To understand the molecular mechanisms behind these functions, targets of c-di-AMP have been identified and characterized. Interestingly, c-di-AMP can bind both proteins and RNA molecules. Several proteins that interact with c-di-AMP are required to control the intracellular potassium concentration. In Bacillus subtilis, c-di-AMP also binds a riboswitch that controls the expression of a potassium transporter. Thus, c-di-AMP is the only known second messenger that controls a biological process by interacting with both a protein and the riboswitch that regulates its expression. Moreover, in Listeria monocytogenes c-di-AMP controls the activity of pyruvate carboxylase, an enzyme that is required to replenish the citric acid cycle. Here, we review the components of the c-di-AMP signaling system.

    Heat-shock factor (HSF) is the master transcriptional regulator of the heat-shock response (HSR) and is essential for stress resilience. HSF is also required for metazoan development; however, its function and regulation in this process are poorly understood. Here, we characterize the genomic distribution and transcriptional activity of Caenorhabditis elegans HSF-1 during larval development and show that the developmental HSF-1 transcriptional program is distinct from the HSR. HSF-1 developmental activation requires binding of E2F/DP to a GC-rich motif that facilitates HSF-1 binding to a heat-shock element (HSE) that is degenerate from the consensus HSE sequence and adjacent to the E2F-binding site at promoters. In contrast, induction of the HSR is independent of these promoter elements or E2F/DP and instead requires a distinct set of tandem canonical HSEs. Together, E2F and HSF-1 directly regulate a gene network, including a specific subset of chaperones, to promote protein biogenesis and anabolic metabolism, which are essential in development.

    2017-05-01

    Information to guide clinicians in educating and advising patients using or intending to use essential oils for self-administered aromatherapy or other medicinal purposes is presented. The term essential oils refers to highly concentrated, aromatic oils extracted from plants by steam distillation, hydrodiffusion, or pressure. Market reports indicate strong growth in the use of essential oils in the United States in recent decades. Therapeutic claims made in the marketing of essential oils have led the Food and Drug Administration to caution a number of suppliers. Along with rapid growth in sales of essential oils to consumers there has been an increase in the amount of published evidence regarding aromatherapy and essential oils; the annual number of relevant articles indexed using Medical Subject Headings terminology has doubled since 2004. In order to help ensure proper application and safe use of essential oils as a self-care modality, healthcare professionals can benefit from a general knowledge of the terminology and foundational concepts of medicinal use of essential oils, as well as resources to facilitate evaluations of appropriateness of use. Because of the increasing popularity of essential oils and the prevalence of essential oil-based self-care practices targeting a wide variety of ailments in the United States, healthcare professionals must be prepared to address concerns about the agents' safety and efficacy. Proper literature evaluation requires the ability to discern the quality of an oil, the safety of administration, and the validity of its use.

    Satellite bacteriophage P4 requires the products of the late genes of a helper phage such as P2 for lytic growth. Expression of the P2 late genes is positively regulated by the P2 ogr gene in a process requiring P2 DNA replication. Transactivation of P2 late gene expression by P4 requires the P4 delta gene product and works even in the absence of P2 DNA replication. We have made null mutants of the P2 ogr and P4 delta genes. In the absence of the P4 delta gene product, P4 multiplication required both the P2 ogr protein and P2 DNA replication. In the absence of the P2 ogr gene product, P4 multiplication required the P4 delta protein. In complementation experiments, we found that the P2 ogr protein was made in the absence of P2 DNA replication but could not function unless P2 DNA replicated. We produced P4 delta protein from a plasmid and found that it complemented the null P4 delta and P2 ogr mutants. Images PMID:2193911

    This report describes the evaluation of a preschool nutrition education program based on the theory of multiple intelligences. Forty-six nutrition educators provided a series of 12 lessons to 6102 preschool-age children. The program was evaluated using a pretest/post-test design to assess differences in fruit and vegetable identification, healthy snack choices, willingness to taste foods, and eating behaviors. Subjects showed significant improvement in food identification and recognition, healthy snack identification, willingness to taste foods, and frequency of fruit, vegetable, meat, and dairy consumption. The evaluation indicates that the program was an effective approach for educating preschool children about nutrition.

    Although essential tremor has been considered the most common movement disorder, it has largely remained a diagnosis of exclusion: many tremor and nontremor features must be absent for the clinical diagnosis to stand. The clinical features of "essential tremor" overlap with or may be part of other tremor disorders and, not surprisingly, this prevalent familial disorder has remained without a gene identified, without a consistent natural history, and without an acceptable pathology or pathophysiologic underpinning. The collective evidence suggests that under the rubric of essential tremor there exists multiple unique diseases, some of which represent cerebellar dysfunction, but for which there is no intrinsic "essence" other than a common oscillatory behavior on posture and action. One approach may be to use the term essential tremor only as a transitional node in the deep phenotyping of tremor disorders based on historical, phenomenological, and neurophysiological features to facilitate its etiologic diagnosis or serve for future gene- and biomarker-discovery efforts. This approach deemphasizes essential tremor as a diagnostic entity and facilitates the understanding of the underlying disorders to develop biologically tailored diagnostic and therapeutic strategies. © 2017 International Parkinson and Movement Disorder Society.

    Streamflow is not measured at every location in a stream network. Yet hydrologists, State and local agencies, and the general public still seek to know streamflow characteristics, such as mean annual flow or flood flows with different exceedance probabilities, at ungaged basins. The goals of this guide are to introduce and familiarize the user with the weighted multiple-linear regression (WREG) program, and to also provide the theoretical background for program features. The program is intended to be used to develop a regional estimation equation for streamflow characteristics that can be applied at an ungaged basin, or to improve the corresponding estimate at continuous-record streamflow gages with short records. The regional estimation equation results from a multiple-linear regression that relates the observable basin characteristics, such as drainage area, to streamflow characteristics.

    Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac142 is a baculovirus core gene and encodes a protein previously shown to associate with occlusion-derived virus (ODV). To determine its role in the baculovirus life cycle, we used the AcMNPV bacmid system to generate an ac142 deletion virus (AcBAC{sup ac142KO-PH-GFP}). Fluorescence and light microscopy revealed that AcBAC{sup ac142KO-PH-GFP} exhibits a single-cell infection phenotype. Titration assays and Western blot confirmed that AcBAC{sup ac142KO-PH-GFP} is unable to produce budded virus (BV). However, viral DNA replication is unaffected and the development of occlusion bodies in AcBAC{sup ac142KO-PH-GFP}-transfected cells evidenced progression to very late phases of the viral infection. Western blot analysis showed that AC142 is expressed in the cytoplasm and nucleus throughout infection and that it is a structural component of BV and ODV which localizes to nucleocapsids. Electron microscopy indicates that ac142 is required for nucleocapsid envelopment to form ODV and their subsequent occlusion, a fundamental process to all baculoviruses.

  5. Cx43 expressed on bone marrow stromal cells plays an essential role in multiple myeloma cell survival and drug resistance

    PubMed Central

    2016-01-01

    Introduction Connexin-43 (Cx43), a connexin constituent of gap junctions (GJs) is mainly expressed in bone marrow stromal cells (BMSCs) and played a important role on hematopoiesis. In this study, we explored the role of gap junctions (GJs) formed by Cx43 between BMSCs and multiple myeloma (MM) cells. Material and methods qPCR and western blot assays were employed to assay Cx43 expression in three MM cell lines (RPMI 8266, U266, and XG7), freshly isolated MM cells, and bone marrow stromal cells (BMSCs). Cx43 mRNA and proteins were detected in all three MM cell lines and six out of seven freshly isolated MM cells. Resuths The BMSCs from MM patients expressed Cx43 at higher levels than of normal donor (ND-BMSCs). Dye transfer assays demonstrated that gap junction intercellular communication (GJIC) occurring via Cx43 situated between MM and BMSCs is functional. Cytometry beads array (CBA) assays showed that cytokines production changed when the ND-BMSCs were co-cultured with MM cells, especially the levels of IL-6, SDF-1α and IL-10 were higher than those the cells cultured alone and decreased significantly in the presence of GJ inhibitor heptanol. Our results demonstrated that the cytotoxicity of BTZ to MM cells decreased significantly in the presence of BMSCs, an effect that was partially recovered in the presence of GJ inhibitor. Conclusions Our data suggest that GJIC between MM and BMSCs is a critical factor in tumor cell proliferation and drug sensitivity, and is implicated in MM pathogenesis. PMID:28144277

  6. A fuzzy goal programming model for the simple U-line balancing problem with multiple objectives

    Toklu, Bilal; Ozcan, Uğur

    2008-03-01

    A fuzzy goal programming model for the simple U-line balancing (SULB) problem with multiple objectives is presented. In real life applications of the SULB problem with multiple objectives, it is difficult for the decision-maker(s) to determine the goal value of each objective precisely as the goal values are imprecise, vague, or uncertain. Therefore a fuzzy goal programming model is developed for this purpose. The proposed model is the first fuzzy multi-objective decision-making approach to the SULB problem with multiple objectives which aims at simultaneously optimizing several conflicting goals. The proposed model is illustrated using an example. A computational study is conducted by solving a large number of test problems to investigate the relationship between the fuzzy goals and to compare them with the goal programming model proposed by Gokcen and Ağpak (Gokcen, H. and Ağpak, K., European Journal of Operational Research, 171, 577-585, 2006). The results of the computational study show that the proposed model is more realistic than the existing models for the SULB problem with multiple objectives and also provides increased flexibility for the decision-maker(s) to determine different alternatives.

    Exercise and leisure activities provide physical and psychosocial benefits to people with multiple sclerosis (MS) and can enhance their quality of life. In Winnipeg, Manitoba, Canada, people with MS have reported barriers to their participation in local MS-specific aquafitness (AF) programs. Therefore, a formal exploration of the accessibility of local AF programs for people with MS was undertaken. The purpose of this phenomenological study was to identify factors that facilitate or impede participation in AF programs by individuals with MS living in Winnipeg. Qualitative data were collected from a total of eight participants through one focus group (n = 7) and one in-depth interview (n = 1). The sample consisted of individuals with MS who were currently participating in AF programming as well as those who were not. Data were audio-recorded and transcribed verbatim, and thematic analysis was completed. Seven themes emerged regarding factors affecting participation in local AF programs. Barriers to participation included inadequate transportation, lack of one-on-one support, environmental inaccessibility, and fears associated with participation in the programs. Facilitators of participation included a knowledgeable instructor and experiencing physical and psychosocial benefits from the program. Information from this study was used locally to advocate for people with MS in order to increase participation in local AF programming. PMID:24453744

  10. An application of a microcomputer compiler program to multiple logistic regression analysis.

    Sakai, R

    1988-01-01

    Microcomputer programs for multiple logistic regression analysis were written in BASIC language to determine the usefulness of microcomputers for multivariate analysis, which is an important method in epidemiological studies. The program, carried out by an interpreter system, required a comparatively long computing time for a small amount of data. For example, it took approximately thirty minutes to compute the data of 6 independent variables and 63 matched sets of case and controls (1:4). The majority of the calculation time was spent computing a matrix. The matrix computation time increased cumulatively in proportion to additions in the number of subjects, and increased exponentially with the number of variables. A BASIC compiler was utilized for the program of multiple logistic regression analysis. The compiled program carried out the same computations as above, but within 4 minutes. Therefore, it is evident that a compiler can be an extremely convenient tool for computing multivariate analysis. The two programs produced here were also easily linked with spreadsheet packages to enter data.

Discussed here are the main functions of CGD and the use of the program to highlight residues of importance in a water channel family. Although CGD was created for protein sequences, most of the modules are compatible with DNA sequences.

    There have been a number of multiple GCM-RCM programs, covering Europe, North America, and now, through CORDEX, most regions of the world. Standard metrics of success for these programs include number of publications, number of users of the data, and number of citations to the program. However, these metrics do not necessarily reflect the scientific value of the program, for example, what new scientific knowledge has been developed. We began to carefully consider how one does establish the scientific value of such programs. We thought that establishing the scientific value of the North American Regional Climate Change Assessment Program (NARCCAP) would be a good way to examine this issue. We present in this paper our assessment of the value of the climate science research produced through the program. These studies include articles that evaluate the current climates of the NARCCAP simulations, analyze the future climate projections, explore temperature and precipitation extremes and apply new statistical techniques to the analyses. A number of articles apply weighting techniques to the ensemble and quantify the uncertainty represented by the ensemble. Of particular interest is determining what we have learned about future climate projections based on the use of higher resolution dynamically generated future climate information. We will evaluate all research articles and major reports (aside from those regarding impacts) that used the NARCCAP database, and we will assess the major research advances indicated in this literature.

  14. The Ghana essential health interventions program: a plausibility trial of the impact of health systems strengthening on maternal & child survival

    2013-01-01

    Background During the 1990s, researchers at the Navrongo Health Research Centre in northern Ghana developed a highly successful community health program. The keystone of the Navrongo approach was the deployment of nurses termed community health officers to village locations. A trial showed that, compared to areas relying on existing services alone, the approach reduced child mortality by half, maternal mortality by 40%, and fertility by nearly a birth — from a total fertility rate of 5.5 in only five years. In 2000, the government of Ghana launched a national program called Community-based Health Planning and Services (CHPS) to scale up the Navrongo model. However, CHPS scale-up has been slow in districts located outside of the Upper East Region, where the “Navrongo Experiment” was first carried out. This paper describes the Ghana Essential Health Intervention Project (GEHIP), a plausibility trial of strategies for strengthening CHPS, especially in the areas of maternal and newborn health, and generating the political will to scale up the program with strategies that are faithful to the original design. Description of the intervention GEHIP improves the CHPS model by 1) extending the range and quality of services for newborns; 2) training community volunteers to conduct the World Health Organization service regimen known as integrated management of childhood illness (IMCI); 3) simplifying the collection of health management information and ensuring its use for decision making; 4) enabling community health nurses to manage emergencies, particularly obstetric complications and refer cases without delay; 5) adding $0.85 per capita annually to district budgets and marshalling grassroots political commitment to financing CHPS implementation; and 6) strengthening CHPS leadership at all levels of the system.

    Ninety-eight patients with definite multiple sclerosis (MS) have been examined. An effect of functional multichannel programmed electrostimulation (FMPES) on the restoration of balance and biomechanics of walking of patients with different types of MS and severity of neurological deficit was estimated. The effectiveness was measured with stabilometric analysis. The method was efficient in patients with mild and moderate degree of neurological deficit severity. Recommendations on the use of FMPES for patients with different disease severity are formulated.

    Postural control disorders are among the most frequent motor disorder symptoms associated with multiple sclerosis. This study aims to demonstrate the potential improvements in postural control among patients with multiple sclerosis who complete a telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. Fifty patients were recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received monitored telerehabilitation treatment via videoconference using the Xbox 360® and Kinect console. Experimental group attended 40 sessions, four sessions per week (20 min per session).The treatment schedule lasted 10 weeks for both groups. A computerized dynamic posturography (Sensory Organization Test) was used to evaluate all patients at baseline and at the end of the treatment protocol. Results showed an improvement over general balance in both groups. Visual preference and the contribution of vestibular information yielded significant differences in the experimental group. Our results demonstrated that a telerehabilitation program based on a virtual reality system allows one to optimize the sensory information processing and integration systems necessary to maintain the balance and postural control of people with multiple sclerosis. We suggest that our virtual reality program enables anticipatory PC and response mechanisms and might serve as a successful therapeutic alternative in situations in which conventional therapy is not readily available.

    2010-04-01

    A common or multiple-demand (MD) pattern of frontal and parietal activity is associated with diverse cognitive demands, and with standard tests of fluid intelligence. In intelligent behaviour, goals are achieved by assembling a series of sub-tasks, creating structured mental programs. Single cell and functional magnetic resonance imaging (fMRI) data indicate a key role for MD cortex in defining and controlling the parts of such programs, with focus on the specific content of a current cognitive operation, rapid reorganization as mental focus is changed, and robust separation of successive task steps. Resembling the structured problem-solving of symbolic artificial intelligence, the mental programs of MD cortex appear central to intelligent thought and action.

    We examined links among three dimensions of youth involvement (intensity, duration, and engagement) in Boy Scouts of America (BSA), an international out-of-school time (OST) youth development program designed to promote moral and performance character in boys. Using data from 737 youth and their parents who participated in one of 40 BSA program sites (commonly referred to as "packs"), we first considered how individual- and pack-level measures of program involvement were differentially linked with character development. Next, we examined whether pack-level involvement characteristics moderate individual-level involvement characteristics, hypothesizing that highly involved packs would serve to further enhance the positive effects of high levels of individual involvement. Results indicated engagement was the strongest, most frequent predictor of increases in both moral and performance character. Although there were no direct effects of pack-level intensity, duration, or engagement, the effects of individual-level engagement were moderated by pack-level engagement, suggesting that the largest increases in moral and performance character occurred among highly engaged youth who were enrolled in highly engaged packs. These results highlight the need to examine multiple dimensions of OST program involvement simultaneously, and suggest that strengthening youth engagement in programming may provide a means for enhancing the positive effects of high-quality youth programming.

    Implementation study is an important tool for deploying state-of-the-art treatments from clinical efficacy studies into a treatment program, with the dual goals of learning about effectiveness of the treatments and improving the quality of care for patients enrolled into the program. In this article, we deal with the design of a treatment program of dynamic treatment regimens (DTRs) for patients with depression post-acute coronary syndrome. We introduce a novel adaptive randomization scheme for a sequential multiple assignment randomized trial of DTRs. Our approach adapts the randomization probabilities to favor treatment sequences having comparatively superior Q-functions used in Q-learning. The proposed approach addresses three main concerns of an implementation study: it allows incorporation of historical data or opinions, it includes randomization for learning purposes, and it aims to improve care via adaptation throughout the program. We demonstrate how to apply our method to design a depression treatment program using data from a previous study. By simulation, we illustrate that the inputs from historical data are important for the program performance measured by the expected outcomes of the enrollees, but also show that the adaptive randomization scheme is able to compensate poorly specified historical inputs by improving patient outcomes within a reasonable horizon. The simulation results also confirm that the proposed design allows efficient learning of the treatments by alleviating the curse of dimensionality.

    1979-01-01

    The role of sensory reinforcement was examined in programming multiple treatment gains in self-stimulation and spontaneous play for developmentally disabled children. Two phases were planned. First, we attempted to identify reinforcers maintaining self-stimulation. Sensory Extinction procedures were implemented in which auditory, proprioceptive, or visual sensory consequences of self-stimulatory behavior were systematically removed and reintroduced in a reversal design. When self-stimulation was decreased or eliminated as a result of removing one of these sensory consequences, the functional sensory consequence was designated as a child's preferred sensory reinforcer. In Phase 2, we assessed whether children would play selectively with toys producing the preferred kind of sensory stimulation. The results showed the following. (1) Self-stimulatory behavior was found to be maintained by sensory reinforcement. When the sensory reinforcer was removed, self-stimulation extinguished. (2) The sensory reinforcers identified for self-stimulatory behavior also served as reinforcers for new, appropriate toy play. (3) The multiple treatment gains observed appeared to be relatively durable in the absence of external reinforcers for play or restraints on self-stimulation. These results illustrate one instance in which multiple behavior change may be programmed in a predictable, lawful fashion by using "natural communities of sensory reinforcement."

    Katoh, Kazutaka; Standley, Daron M

    2016-07-01

    We present a new feature of the MAFFT multiple alignment program for suppressing over-alignment (aligning unrelated segments). Conventional MAFFT is highly sensitive in aligning conserved regions in remote homologs, but the risk of over-alignment is recently becoming greater, as low-quality or noisy sequences are increasing in protein sequence databases, due, for example, to sequencing errors and difficulty in gene prediction. The proposed method utilizes a variable scoring matrix for different pairs of sequences (or groups) in a single multiple sequence alignment, based on the global similarity of each pair. This method significantly increases the correctly gapped sites in real examples and in simulations under various conditions. Regarding sensitivity, the effect of the proposed method is slightly negative in real protein-based benchmarks, and mostly neutral in simulation-based benchmarks. This approach is based on natural biological reasoning and should be compatible with many methods based on dynamic programming for multiple sequence alignment. The new feature is available in MAFFT versions 7.263 and higher. http://mafft.cbrc.jp/alignment/software/ katoh@ifrec.osaka-u.ac.jp Supplementary data are available at Bioinformatics online. © The Author 2016.

  8. On control of singleton attractors in multiple Boolean networks: integer programming-based method

    2014-01-01

    Background Boolean network (BN) is a mathematical model for genetic network and control of genetic networks has become an important issue owing to their potential application in the field of drug discovery and treatment of intractable diseases. Early researches have focused primarily on the analysis of attractor control for a randomly generated BN. However, one may also consider how anti-cancer drugs act in both normal and cancer cells. Thus, the development of controls for multiple BNs is an important and interesting challenge. Results In this article, we formulate three novel problems about attractor control for two BNs (i.e., normal cell and cancer cell). The first is about finding a control that can significantly damage cancer cells but has a limited damage to normal cells. The second is about finding a control for normal cells with a guaranteed damaging effect on cancer cells. Finally, we formulate a definition for finding a control for cancer cells with limited damaging effect on normal cells. We propose integer programming-based methods for solving these problems in a unified manner, and we conduct computational experiments to illustrate the efficiency and the effectiveness of our method for our multiple-BN control problems. Conclusions We present three novel control problems for multiple BNs that are realistic control models for gene regulation networks and adopt an integer programming approach to address these problems. Experimental results indicate that our proposed method is useful and effective for moderate size BNs. PMID:24565276

    The Department of Energy, Richland Operations (DOE-RL) recently restructured its Hanford work scope, awarding two new contracts over the past several months for a total of three contracts to manage the sites cleanup efforts. DOE-RL met with key contractor personnel prior to and during contract transition to ensure site welding activities had appropriate oversight and maintained code compliance. The transition also provided an opportunity to establish a single site-wide function that would provide welding and materials engineering services to the Hanford site contractors: CH2M HILL Plateau Remediation Company (CHPRC); Mission Support Alliance (MSA); Washington River Protection Solutions (WRPS); and Washington Closure Hanford (WCH). Over the years, multiple and separate welding programs (amongst the several contractors) existed at the Hanford site leading to inefficiencies resulting from duplication of administrative efforts, maintenance of welding procedures, welder performance certifications, etc. The new, single program eliminates these inefficiencies. The new program, co-managed by two of the sites' new contractors, the CHPRC ('owner' of the program and responsible for construction welding services) and the MSA (provides maintenance welding services), provides more than just the traditional construction and maintenance welding services. Also provided, are welding engineering, specialty welding development/qualification for the closure of radioactive materials containers and materials evaluation/failure analysis. The following describes the new Hanford site welding program.

    The purpose of this research study was to examine the effect of a multiple risky behaviors prevention program applied comprehensively throughout an entire school system involving universal, selective, and indicated levels of students at a local private high school during a 4-year period. The noncurriculum prevention program was created based upon the key elements of effective prevention programming and the need to address the growing variety of risky behaviors that the youth face today. Results (n = 469 to 614) indicated that 7 out of 15 risky behaviors statistically significantly decreased throughout the 4-year study, with 6 behaviors involving alcohol and drugs. However, many of the targeted non-substance-use risky behaviors displayed inconsistent prevalence rate patterns without statistically significant changes. These findings indicate that the frequency and intensity of programming for non-substance-use behaviors should be increased to a value at least equal to that of the substance-use behaviors. Implications for schools, prevention specialists, and future program development and research are discussed. PMID:27672475

    This study compared trunk exercises based on the Bobath concept with routine neurorehabilitation approaches in multiple sclerosis (MS). Bobath and routine neurorehabilitation exercises groups were evaluated. MS cases were divided into two groups. Both groups joined a 3 d/wk rehabilitation program for 8 wk. The experimental group performed trunk exercises based on the Bobath concept, and the control group performed routine neurorehabilitation exercises. Additionally, both groups performed balance and coordination exercises. All patients were evaluated with the Trunk Impairment Scale (TIS), Berg Balance Scale (BBS), International Cooperative Ataxia Rating Scale (ICARS), and Multiple Sclerosis Functional Composite (MSFC) before and after the physiotherapy program. In group analysis, TIS, BBS, ICARS, and MSFC scores and strength of abdominal muscles were significantly different after treatment in both groups (p < 0.05). When the groups were compared, no significant differences were found in any parameters (p > 0.05). Although trunk exercises based on the Bobath concept are rarely applied in MS rehabilitation, the results of this study show that they are as effective as routine neurorehabilitation exercises. Therefore, trunk exercises based on the Bobath concept can be beneficial in MS rehabilitation programs.

    This paper presents an innovative hands-on training program designed to create a pipeline of highly-skilled technical workers for today's workforce economy. The 2+2+2 Pennsylvania Integrated Workforce Leadership Program in Electro-Optics prepares students for a career in this new high-tech field. With seamless transition from high school into college, the program offers the versatility of multiple entrance and exit pathways. After completion of each educational level, students can exit the program with various skill levels, including certificates, an associate's degree, or a bachelor's degree. Launched by Indiana University of Pennsylvania (IUP) in partnership with Lenape Vocational School (Lenape), the 2+2+2 educational pathway program was implemented to promote early training of high-school students. During the first level, students in their junior and/or senior year enroll in four Electro-Optics courses at Lenape. Upon completion of these courses and an Advanced Placement Equivalency course with an appropriate exam score, students can earn a certificate from Lenape for the 15+ credits, which also can be articulated into IUP's associate degree program in Electro-Optics. During the second level, students can earn an associate's degree in Electro-Optics, offered only at the IUP Northpointe Campus. After completion of the Associate in Applied Science (A.A.S.), students are prepared to enter the workforce as senior technicians. During the third level, students who have completed the Associate of Science (A.S.) in Electro-Optics have the opportunity to matriculate at IUP's Indiana Campus to earn a Bachelor of Science (B.S.) degree in Applied Physics with a track in Electro-Optics. Hence, the name 2+2+2 refers to getting started in high school, continuing the educational experience with an associate's degree program, and optionally moving on to a bachelor's degree. Consequently, students move from one educational level to the next with advanced credits toward the next

    2010-03-01

    The foundation of a logic model or any theory-based planning model is the identification of the behavioral antecedents and the relationship of these variables to the target behavior. Applying theoretical concepts to specific behaviors and populations is often challenging for practitioners and program planning students. The challenge comes from the abstract definition of theoretical constructs, the duplication of similar constructs in multiple theories, and the need to combine multiple theories. To simplify the planning process when utilizing logic models and health behavior theory, we recommend the use of the PER Worksheet. The PER Worksheet is a planning tool that provides layman-term prompts for identifying health behavior antecedents. It encompasses five common health behavior theories-health belief model, theory of planned behavior, social cognitive theory, an ecological perspective, and transtheoretical model. The PER Worksheet is organized into three columns: Predisposing, Enabling, and Reinforcing factors, terms of the PRECEDE/PROCEED model.

    2012-02-01

    The objective of this analysis was to compare the rumen submodel predictions of 4 commonly used dairy ration programs to observed values of duodenal flows of crude protein (CP), protein fractions, and essential AA (EAA). The literature was searched and 40 studies, including 154 diets, were used to compare observed values with those predicted by AminoCow (AC), Agricultural Modeling and Training Systems (AMTS), Cornell-Penn-Miner (CPM), and National Research Council 2001 (NRC) models. The models were evaluated based on their ability to predict the mean, their root mean square prediction error (RMSPE), error bias, and adequacy of regression equations for each protein fraction. The models predicted the mean duodenal CP flow within 5%, with more than 90% of the variation due to random disturbance. The models also predicted within 5% the mean microbial CP flow except CPM, which overestimated it by 27%. Only NRC, however, predicted mean rumen-undegraded protein (RUP) flows within 5%, whereas AC and AMTS underpredicted it by 8 to 9% and CPM by 24%. Regarding duodenal flows of individual AA, across all diets, CPM predicted substantially greater (>10%) mean flows of Arg, His, Ile, Met, and Lys; AMTS predicted greater flow for Arg and Met, whereas AC and NRC estimations were, on average, within 10% of observed values. Overpredictions by the CPM model were mainly related to mean bias, whereas the NRC model had the highest proportion of bias in random disturbance for flows of EAA. Models tended to predict mean flows of EAA more accurately on corn silage and alfalfa diets than on grass-based diets, more accurately on corn grain-based diets than on non-corn-based diets, and finally more accurately in the mid range of diet types. The 4 models were accurate at predicting mean dry matter intake. The AC, AMTS, and NRC models were all sufficiently accurate to be used for balancing EAA in dairy rations under field conditions.

    NEWRAP, an improved version of a previous multiple linear regression program called RAPIER, CREDUC, and CRSPLT, allows for a complete regression analysis including cross plots of the independent and dependent variables, correlation coefficients, regression coefficients, analysis of variance tables, t-statistics and their probability levels, rejection of independent variables, plots of residuals against the independent and dependent variables, and a canonical reduction of quadratic response functions useful in optimum seeking experimentation. A major improvement over RAPIER is that all regression calculations are done in double precision arithmetic.

    Newts have the ability to repeatedly regenerate their lens even during ageing. However, it is unclear whether this regeneration reflects an undisturbed genetic activity. To answer this question, we compared the transcriptomes of lenses, irises and tails from aged newts that had undergone lens regeneration 19 times with the equivalent tissues from young newts that had never experienced lens regeneration. Our analysis indicates that repeatedly regenerated lenses showed a robust transcriptional program comparable to young never-regenerated lenses. In contrast, the tail, which was never regenerated, showed gene expression signatures of ageing. Our analysis strongly suggests that, with respect to gene expression, the regenerated lenses have not deviated from a robust transcriptional program even after multiple events of regeneration throughout the life of the newt. In addition, our study provides a new paradigm in biology, and establishes the newt as a key model for the study of regeneration in relation to ageing.

    Setting goals can be a valuable skill to self-manage multiple sclerosis (MS) fatigue. A better understanding of the goals set by people with MS after completing a fatigue management program can assist health care professionals with tailoring interventions for clients. This study aimed to describe the focus of goals set by people with MS after a teleconference-delivered fatigue management program and to evaluate the extent to which participants were able to achieve their goals over time. In total, 485 goals were set by 81 participants. Over a follow-up period, 64 participants rated 284 goals regarding progress made toward goal achievement. Approximately 50% of the rated goals were considered achieved. The most common type of goal achieved was that of instrumental activities of daily living. Short-term goals were more likely to be achieved. This study highlights the need for and importance of promoting and teaching goal-setting skills to people with MS.

    Balance and mobility impairments are common in persons with multiple sclerosis (MS). The primary purpose of this pilot program was to evaluate the feasibility and the effects of group kickboxing on balance and mobility in individuals with MS. Four individuals with relapsing-remitting or secondary progressive MS participated in a group kickboxing program two times per week for 8 weeks. Outcome measures included the Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go (TUG), walking speed and the Activities Specific Balance Confidence Scale (ABC). Following training, 3 of 4 participants had improvements in BBS performance. All participants demonstrated improvements in the DGI. Changes in the TUG, ABC, and walking speed were more variable. Group kickboxing appears to be a feasible exercise activity for individuals with MS and may lead to improvement in select measures of balance. Further investigation may be warranted.

    Background: Muscle weakness and fatigue contribute to the reduction of daily activity in multiple sclerosis (MS) patients. Therapeutic strategies to promote improvements in muscle strength and endurance are limited in individuals with MS. Some evidence showed that exercise may improve and affect different aspects of the disease including quality of life, fatigue, motor and cognitive functions. Objectives: To investigate the value of resistance training of moderate to high intensity on motor function, muscle strength, balance and perceived disability in male patients with multiple sclerosis compared to a control group. Patients and Methods: 20 male patients with MS (mean ± SD, age: 34.05 ± 7.8 y; Expanded Disability Status Scale (EDSS): 2.94 ± 1.5) were recruited and randomized either to the exercise (E) or control group (C). Group E participated in a three-time weekly individualized progressive resistance-training program (both upper and lower extremities) for eight weeks, while group C was advised not to change their physical activity habits. All initial measures (including EDSS, balance, muscle strength, and functional mobility) were re-evaluated at the end of the program. Results: Two patients of group E left the program. The other eight subjects completed the program with no MS-related exacerbations/complications. There was a significant change in 2 of 3 aspects of ambulatory function [Three minutes step test (P = 0.001), Timed Up and Go test (P = 0.009)], muscle strength (P = 0.000), and EDSS (P = 0.014). Comparing the two groups, we did not observe any significant change in “Balance” (P = 0.407). Conclusions: The resistance training of moderate to high intensity was well-tolerated in MS patients and may be an effective intervention for improving muscle strength, functional ability and EDSS-based disease severity.

    Nonsense-mediated decay (NMD) is an important process that is best known for degrading transcripts that contain premature stop codons (PTCs) to mitigate their potentially harmful consequences, although its regulatory role encompasses other classes of transcripts as well. Despite the critical role of NMD at the cellular level, our knowledge about the consequences of deficiency of its components at the organismal level is largely limited to model organisms. In this study, we report two consanguineous families in which a similar pattern of congenital anomalies was found to be most likely caused by homozygous loss-of-function mutations in SMG9, encoding an essential component of the SURF complex that generates phospho-UPF1, the single most important step in NMD. By knocking out Smg9 in mice via CRISPR/Cas9, we were able to recapitulate the major features of the SMG9-related multiple congenital anomaly syndrome we observed in humans. Surprisingly, human cells devoid of SMG9 do not appear to have reduction of PTC-containing transcripts but do display global transcriptional dysregulation. We conclude that SMG9 is required for normal human and murine development, most likely through a transcriptional regulatory role, the precise nature of which remains to be determined. PMID:27018474

    Protein-protein interactions are fundamentally important in many biological processes and it is in pressing need to understand the principles of protein-protein interactions. Mutagenesis studies have found that only a small fraction of surface residues, known as hot spots, are responsible for the physical binding in protein complexes. However, revealing hot spots by mutagenesis experiments are usually time consuming and expensive. In order to complement the experimental efforts, we propose a new computational approach in this paper to predict hot spots. Our method, Rough Set-based Multiple Criteria Linear Programming (RS-MCLP), integrates rough sets theory and multiple criteria linear programming to choose dominant features and computationally predict hot spots. Our approach is benchmarked by a dataset of 904 alanine-mutated residues and the results show that our RS-MCLP method performs better than other methods, e.g., MCLP, Decision Tree, Bayes Net, and the existing HotSprint database. In addition, we reveal several biological insights based on our analysis. We find that four features (the change of accessible surface area, percentage of the change of accessible surface area, size of a residue, and atomic contacts) are critical in predicting hot spots. Furthermore, we find that three residues (Tyr, Trp, and Phe) are abundant in hot spots through analyzing the distribution of amino acids.

    Drinking water may contain pollutants that harm human health. The frequency of pollutant monitoring may occur quarterly, annually, or less frequently, depending upon the pollutant, the pollutant concentration, and community water system. However, birth and other health outcomes are associated with narrow time-windows of exposure. Infrequent monitoring impedes linkage between water quality and health outcomes for epidemiological analyses. To evaluate the performance of multiple imputation to fill in water quality values between measurements in community water systems (CWSs). The multiple imputation method was implemented in a simulated setting using data from the Atrazine Monitoring Program (AMP, 2006-2009 in five Midwestern states). Values were deleted from the AMP data to leave one measurement per month. Four patterns reflecting drinking water monitoring regulations were used to delete months of data in each CWS: three patterns were missing at random and one pattern was missing not at random. Synthetic health outcome data were created using a linear and a Poisson exposure-response relationship with five levels of hypothesized association, respectively. The multiple imputation method was evaluated by comparing the exposure-response relationships estimated based on multiply imputed data with the hypothesized association. The four patterns deleted 65-92% months of atrazine observations in AMP data. Even with these high rates of missing information, our procedure was able to recover most of the missing information when the synthetic health outcome was included for missing at random patterns and for missing not at random patterns with low-to-moderate exposure-response relationships. Multiple imputation appears to be an effective method for filling in water quality values between measurements. Copyright © 2014 Elsevier Inc. All rights reserved.

    Individuals with multiple sclerosis (MS) have many barriers to health care and participate in less health promotion activities than the general population. The current feasibility project was a trial implementation of an existing telehealth promotion program within a community neurology clinic with a single MS provider. The program comprised an initial face-to-face meeting followed by five scheduled telephone calls over a 12-week period. Progress was facilitated through motivational interviewing techniques and performed by a MS-certified nurse working as a nurse navigator in the clinic. Of 10 participants, nine (90%) showed overall progress toward their goals over 12 weeks. Within limits of a feasibility pilot, the program showed positive patient outcomes and was well received by participants and not a burden to clinic staff. The delivery model eliminates many barriers to care and increases patient satisfaction with the clinic while keeping costs to the clinic low.

  14. Utilization of Host Iron Sources by Corynebacterium diphtheriae: Multiple Hemoglobin-Binding Proteins Are Essential for the Use of Iron from the Hemoglobin-Haptoglobin Complex

    The use of hemin iron by Corynebacterium diphtheriae requires the DtxR- and iron-regulated ABC hemin transporter HmuTUV and the secreted Hb-binding protein HtaA. We recently described two surface anchored proteins, ChtA and ChtC, which also bind hemin and Hb. ChtA and ChtC share structural similarities to HtaA; however, a function for ChtA and ChtC was not determined. In this study, we identified additional host iron sources that are utilized by C. diphtheriae. We show that several C. diphtheriae strains use the hemoglobin-haptoglobin (Hb-Hp) complex as an iron source. We report that an htaA deletion mutant of C. diphtheriae strain 1737 is unable to use the Hb-Hp complex as an iron source, and we further demonstrate that a chtA-chtC double mutant is also unable to use Hb-Hp iron. Single-deletion mutants of chtA or chtC use Hb-Hp iron in a manner similar to that of the wild type. These findings suggest that both HtaA and either ChtA or ChtC are essential for the use of Hb-Hp iron. Enzyme-linked immunosorbent assay (ELISA) studies show that HtaA binds the Hb-Hp complex, and the substitution of a conserved tyrosine (Y361) for alanine in HtaA results in significantly reduced binding. C. diphtheriae was also able to use human serum albumin (HSA) and myoglobin (Mb) but not hemopexin as iron sources. These studies identify a biological function for the ChtA and ChtC proteins and demonstrate that the use of the Hb-Hp complex as an iron source by C. diphtheriae requires multiple iron-regulated surface components.

    2011-07-01

    A clinical research program for drug development often consists of a sequence of clinical trials that may begin with uncontrolled and nonrandomized trials, followed by randomized trials or randomized controlled trials. Adaptive designs are not infrequently proposed for use. In the regulatory setting, the success of a drug development program can be defined to be that the experimental treatment at a specific dose level including regimen and frequency is approved based on replicated evidence from at least two confirmatory trials. In the early stage of clinical research, multiplicity issues are very broad. What is the maximum tolerable dose in an adaptive dose escalation trial? What should the dose range be to consider in an adaptive dose-ranging trial? What is the minimum effective dose in an adaptive dose-response study given the tolerability and the toxicity observable in short term or premarketing trials? Is establishing the dose-response relationship important or the ability to select a superior treatment with high probability more important? In the later stage of clinical research, multiplicity problems can be formulated with better focus, depending on whether the study is for exploration to estimate or select design elements or for labeling consideration. What is the study objective for an early-phase versus a later phase adaptive clinical trial? How many doses are to be studied in the early exploratory adaptive trial versus in the confirmatory adaptive trial? Is the intended patient population well defined or is the applicable patient population yet to be adaptively selected in the trial due to the potential patient and/or disease heterogeneity? Is the primary efficacy endpoint well defined or still under discussion providing room for adaptation? What are the potential treatment indications that may adaptively lead to an intended-to-treat patient population and the primary efficacy endpoint? In this work we stipulate the multiplicity issues with adaptive

    Highlights: Black-Right-Pointing-Pointer Inexact piecewise-linearization-based fuzzy flexible programming is proposed. Black-Right-Pointing-Pointer It's the first application to waste management under multiple complexities. Black-Right-Pointing-Pointer It tackles nonlinear economies-of-scale effects in interval-parameter constraints. Black-Right-Pointing-Pointer It estimates costs more accurately than the linear-regression-based model. Black-Right-Pointing-Pointer Uncertainties are decreased and more satisfactory interval solutions are obtained. - Abstract: To tackle nonlinear economies-of-scale (EOS) effects in interval-parameter constraints for a representative waste management problem, an inexact piecewise-linearization-based fuzzy flexible programming (IPFP) model is developed. In IPFP, interval parameters for waste amounts and transportation/operation costs can be quantified; aspiration levels for net system costs, as well as tolerance intervals for both capacities of waste treatment facilities and waste generation rates can be reflected; and the nonlinear EOS effects transformed from objective function to constraints can be approximated. An interactive algorithm is proposed for solving the IPFP model, which in nature is an interval-parameter mixed-integer quadratically constrained programming model. To demonstrate the IPFP's advantages, two alternative models are developed to compare their performances. One is a conventional linear-regression-based inexact fuzzy programming model (IPFP2) and the other is an IPFP model with all right-hand-sides of fussy constraints being the corresponding interval numbers (IPFP3). The comparison results between IPFP and IPFP2 indicate that the optimized waste amounts would have the similar patterns in both models. However, when dealing with EOS effects in constraints, the IPFP2 may underestimate the net system costs while the IPFP can estimate the costs more accurately. The comparison results between IPFP and IPFP3 indicate

    Newly activated CD8+ T cells reprogram their metabolism to meet the extraordinary biosynthetic demands of clonal expansion; however, the signals mediating metabolic reprogramming remain poorly defined. Herein, we demonstrate an essential role for sterol regulatory element binding proteins (SREBPs) in the acquisition of effector cell metabolism. Without SREBP signaling, CD8+ T cells are unable to blast, resulting in markedly attenuated clonal expansion during viral infection. Mechanistic studies indicate that SREBPs are essential to meet the heightened lipid requirements of membrane synthesis during blastogenesis. SREBPs are dispensable for homeostatic proliferation, indicating a context-specific requirement for SREBPs in effector responses. These studies provide insights into the molecular signals underlying metabolic reprogramming of CD8+ T cells during the transition from quiescence to activation. PMID:23563690

    To improve walking and other aspects of physical function with a progressive 6-month exercise program in patients with multiple sclerosis (MS). MS patients with mild to moderate disability (Expanded Disability Status Scale scores 1.0 to 5.5) were randomly assigned to an exercise or control group. The intervention consisted of strength and aerobic training initiated during 3-week inpatient rehabilitation and continued for 23 weeks at home. The groups were evaluated at baseline and at 6 months. The primary outcome was walking speed, measured by 7.62 m and 500 m walk tests. Secondary outcomes included lower extremity strength, upper extremity endurance and dexterity, peak oxygen uptake, and static balance. An intention-to-treat analysis was used. Ninety-one (96%) of the 95 patients entering the study completed it. Change between groups was significant in the 7.62 m (p = 0.04) and 500 m walk tests (p = 0.01). In the 7.62 m walk test, 22% of the exercising patients showed clinically meaningful improvements. The exercise group also showed increased upper extremity endurance as compared to controls. No other noteworthy exercise-induced changes were observed. Exercise adherence varied considerably among the exercisers. Walking speed improved in this randomized study. The results confirm that exercise is safe for multiple sclerosis patients and should be recommended for those with mild to moderate disability.

    The aim of this study was to assess the utility of long term faculty development programs (FDPs) in order to improve the quality of multiple choice questions (MCQs) items' writing. This was a quasi-experimental study, conducted with newly joined faculty members. The MCQ items were analyzed for difficulty index, discriminating index, reliability, Bloom's cognitive levels, item writing flaws (IWFs) and MCQs' nonfunctioning distractors (NFDs) based test courses of respiratory, cardiovascular and renal blocks. Significant improvement was found in the difficulty index values of pre- to post-training (p = 0.003). MCQs with moderate difficulty and higher discrimination were found to be more in the post-training tests in all three courses. Easy questions were decreased from 36.7 to 22.5%. Significant improvement was also reported in the discriminating indices from 92.1 to 95.4% after training (p = 0.132). More number of higher cognitive level of Bloom's taxonomy was reported in the post-training test items (p<0.0001). Also, NFDs and IWFs were reported less in the post-training items (p<0.02). The MCQs written by the faculties without participating in FDPs are usually of low quality. This study suggests that newly joined faculties need active participation in FDPs as these programs are supportive in improving the quality of MCQs' items writing. PMID:25828516

    Newts have the ability to repeatedly regenerate their lens even during ageing. However, it is unclear whether this regeneration reflects an undisturbed genetic activity. To answer this question, we compared the transcriptomes of lenses, irises and tails from aged newts that had undergone lens regeneration 19 times with the equivalent tissues from young newts that had never experienced lens regeneration. Our analysis indicates that repeatedly regenerated lenses showed a robust transcriptional program comparable to young never-regenerated lenses. In contrast, the tail, which was never regenerated, showed gene expression signatures of ageing. Our analysis strongly suggests that, with respect to gene expression, the regenerated lenses have not deviated from a robust transcriptional program even after multiple events of regeneration throughout the life of the newt. In addition, our study provides a new paradigm in biology, and establishes the newt as a key model for the study of regeneration in relation to ageing.

    Children with Multiple Risk Factor Exposition Benefit from the German "Strengthening Families Program" The German adaptation of the substance use-preventive family-based Strengthening Families Program 10-14 (SFP, Iowa version) was evaluated in a longitudinal two-year follow-up trial. Participants were N = 292 children with a mean age of twelve years at baseline, and N = 292 parents. We employed a multi-centric, randomized-controlled, two-armed (SFP vs. minimal control condition) study design. Following a "risk moderation hypothesis", we assumed that children with an elevated risk-exposition R(+) would benefit more than children with a low risk-exposition R(-) irrespective of the preventive intervention, and that R(+) under SFP would benefit more than R(+) under the minimal control condition. "Risk-exposition" was measured in correspondence with the Communities That Care Youth Survey-questionnaire. A total of 28 % of children were classified with an elevated risk level. Children's reports confirmed our hypothesis: R(+) report a total of eleven improvements, four of these being significantly more distinct than in the other groups (Anxiety-Depressivity, Punitive Parenting of mother, Punitive Parenting of father, Unbalanced family functioning). In three measures an improvement appears solely in R(+) under SFP (Satisfaction with family functioning, School Attachment and Peer Relationship Quality, Quality of Life). Parents' reports showed a similar tendency, but were less pronounced.

    To tackle nonlinear economies-of-scale (EOS) effects in interval-parameter constraints for a representative waste management problem, an inexact piecewise-linearization-based fuzzy flexible programming (IPFP) model is developed. In IPFP, interval parameters for waste amounts and transportation/operation costs can be quantified; aspiration levels for net system costs, as well as tolerance intervals for both capacities of waste treatment facilities and waste generation rates can be reflected; and the nonlinear EOS effects transformed from objective function to constraints can be approximated. An interactive algorithm is proposed for solving the IPFP model, which in nature is an interval-parameter mixed-integer quadratically constrained programming model. To demonstrate the IPFP's advantages, two alternative models are developed to compare their performances. One is a conventional linear-regression-based inexact fuzzy programming model (IPFP2) and the other is an IPFP model with all right-hand-sides of fussy constraints being the corresponding interval numbers (IPFP3). The comparison results between IPFP and IPFP2 indicate that the optimized waste amounts would have the similar patterns in both models. However, when dealing with EOS effects in constraints, the IPFP2 may underestimate the net system costs while the IPFP can estimate the costs more accurately. The comparison results between IPFP and IPFP3 indicate that their solutions would be significantly different. The decreased system uncertainties in IPFP's solutions demonstrate its effectiveness for providing more satisfactory interval solutions than IPFP3. Following its first application to waste management, the IPFP can be potentially applied to other environmental problems under multiple complexities.

    Evidence suggests that choice of setting may be important in influencing the outcomes of rehabilitation programs, as well as optimizing participant satisfaction and adherence. This article aims to examine the factors that may inform the choice of setting for a falls-prevention program tailored to the needs of people with multiple sclerosis, including the influence of setting on program effectiveness, participant engagement, cost, and sustainability. Any new program should ensure that the choice of setting is informed by the intended program outcomes as well as an awareness of the opportunities and challenges presented by each type of setting. Evaluations of falls programs for older people suggest that immediate outcomes are similar regardless of setting; however, long-term outcomes may differ by setting, possibly owing to differential effects on adherence. Programs based away from home may offer benefits in terms of maintaining motivation, providing peer-support opportunities, and allowing regular access to facilitator input, while home-based programs offer unique opportunities for context-based practice and the integration of falls-prevention activities into real life. Additionally, home-based programs may address some of the long-term feasibility issues associated with programs away from home. A "mixed" program incorporating elements of home- and community-based activity may be the most sustainable and effective choice to achieve both long- and short-term goals within a falls-prevention program. However, currently there are significant gaps in knowledge relating to comparative program outcomes, cost, and long-term sustainability.

    Clinical distinction of Parkinson's disease (PD) from multiple system atrophy (MSA) or essential tremor (ET) is sometimes difficult. The purpose of this study was to assess changes in cardiac sympathetic nerve function in PD, MSA, and ET by (131)I-MIBG myocardial scintigraphy METHODS: Patients with PD (25), MSA (18), or ET (11) and 10 healthy controls (HC) were enrolled. (131)I-MIBG myocardial scintigraphy was performed for each subject, and heart/mediastinum (H/M) ratios were calculated at two sample times (15min and 4h after the injection of (131)I-MIBG), representing the (131)I-MIBG myocardial uptake ratios. The washout ratio (WOR) of MIBG which indicates the activity tone of the presynaptic sympathetic nerves was calculated for each subject. The H/M ratios at the two sample times (15min and 4h) were 1.65±0.36 and 1.50±0.43 in the PD group, 1.97±0.36 and 2.08±0.57 in the MSA group, 2.34±0.34 and 2.46±0.51 in the ET group, and 2.41±0.26 and 2.66±0.47 in the HC group. The H/M ratios at the two sample times were lower in the PD group than in the MSA, ET, or HC groups, with statistical significance (all P<0.05). The H/M ratios at the two sample times were significantly lower in the MSA group than in the HC group (all P<0.05). There was no significant difference in H/M ratios at either sample time between the ET and HC group (all P>0.05). The washout ratios (WORs) of MIBG were significantly increased in PD group compared with those in MSA, ET and HC groups. In subgroup analysis, The H/M ratios at the two sample times were decreased in early PD group compared with those in early MSA and early ET groups, with statistical significance (all P<0.05). Cardiac sympathetic dysfunction can occur in both PD and MSA patients, especially in PD patients, whereas it remains normal in ET patients. (131)I-MIBG myocardial scintigraphy can help distinguish patients with PD from those with MSA or ET with good sensitivity and specificity. Copyright © 2016 Elsevier B.V. All

    2014-01-01

    Here I present an Excel based program for the analysis of intracellular Ca transients recorded using fluorescent indicators. The program can perform all the necessary steps which convert recorded raw voltage changes into meaningful physiological information. The program performs two fundamental processes. (1) It can prepare the raw signal by several methods. (2) It can then be used to analyze the prepared data to provide information such as absolute intracellular Ca levels. Also, the rates of change of Ca can be measured using multiple, simultaneous regression analysis. I demonstrate that this program performs equally well as commercially available software, but has numerous advantages, namely creating a simplified, self-contained analysis workflow.

  9. San Diego Multiple Species Conservation Program (MSCP) Rare Plant Monitoring Review and Revision

    2007-01-01

    Introduction The San Diego Multiple Species Conservation Program (MSCP) was developed for the conservation of plants and animals in the south part of San Diego County, under the California Natural Community Conservation Planning Act of 1991 (California Department of Fish and Game) and the Federal Endangered Species Act of 1973, as amended (16 U.S. Code 1531-1544.) The Program is on the leading edge of conservation, as it seeks to both guide development and conserve at-risk species with the oversight of both State and Federal agencies. Lands were identified for inclusion in the MSCP based on their value as habitat for at-risk plants or plant communities (Natural Community Conservation Planning, 2005). Since its inception in the mid-1990s the Program has protected over 100,000 acres, involving 15 jurisdictions and the U.S. Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG) in the conservation of 87 taxa. Surveys for covered species have been conducted, and management and monitoring have been implemented at some high priority sites. Each jurisdiction or agency manages and monitors their conservation areas independently, while collaborating regionally for long-term protection. The San Diego MSCP is on the forefront of conservation, in one of the most rapidly growing urban areas of the country. The planning effort that developed the MSCP was state-of-the-art, using expert knowledge, spatial habitat modeling, and principles of preserve design to identify and prioritize areas for protection. Land acquisition and protection are ahead of schedule for most jurisdictions. Surveys have verified the locations of many rare plant populations known from earlier collections, and they provide general information on population size and health useful for further conservation planning. Management plans have been written or are in development for most MSCP parcels under jurisdictional control. Several agencies are developing databases for implementation

    Background Refugees are at an increased risk of chronic Hepatitis B Virus (HBV) infection because many of their countries of origin, as well as host countries, have intermediate-to-high prevalence rates. Refugees arriving to the US are also at risk of serious sequelae from chronic HBV infection because they are not routinely screened for the virus overseas or in domestic post-arrival exams, and may live in the US for years without awareness of their infection status. Methods A cohort of 26,548 refugees who arrived in Minnesota and Georgia during 2005–2010 was evaluated to determine the prevalence of chronic HBV infection. This prevalence information was then used in a cost-benefit analysis comparing two variations of a proposed overseas program to prevent or ameliorate the effects of HBV infection, titled ‘Screen, then vaccinate or initiate management’ (SVIM) and ‘Vaccinate only’ (VO). The analyses were performed in 2013. All values were converted to US 2012 dollars. Results The estimated six year period-prevalence of chronic HBV infection was 6.8% in the overall refugee population arriving to Minnesota and Georgia and 7.1% in those ≥ 6 years of age. The SVIM program variation was more cost beneficial than VO. While the up-front costs of SVIM were higher than VO ($154,084 vs. $73,758; n=58,538 refugees), the SVIM proposal displayed a positive net benefit, ranging from $24 million to $130 million after only 5 years since program initiation, depending on domestic post-arrival screening rates in the VO proposal. Conclusions Chronic HBV infection remains an important health problem in refugees resettling to the United States. An overseas screening policy for chronic HBV infection is more cost-beneficial than a ‘Vaccination only’ policy. The major benefit drivers for the screening policy are earlier medical management of chronic HBV infection and averted lost societal contributions from premature death. PMID:25595868

  12. Cross-scale Efficient Tensor Contractions for Coupled Cluster Computations Through Multiple Programming Model Backends

    2016-07-26

    Coupled-cluster methods provide highly accurate models of molecular structure by explicit numerical calculation of tensors representing the correlation between electrons. These calculations are dominated by a sequence of tensor contractions, motivating the development of numerical libraries for such operations. While based on matrix-matrix multiplication, these libraries are specialized to exploit symmetries in the molecular structure and in electronic interactions, and thus reduce the size of the tensor representation and the complexity of contractions. The resulting algorithms are irregular and their parallelization has been previously achieved via the use of dynamic scheduling or specialized data decompositions. We introduce our efforts to extend the Libtensor framework to work in the distributed memory environment in a scalable and energy efficient manner. We achieve up to 240 speedup compared with the best optimized shared memory implementation. We attain scalability to hundreds of thousands of compute cores on three distributed-memory architectures, (Cray XC30&XC40, BlueGene/Q), and on a heterogeneous GPU-CPU system (Cray XK7). As the bottlenecks shift from being compute-bound DGEMM's to communication-bound collectives as the size of the molecular system scales, we adopt two radically different parallelization approaches for handling load-imbalance. Nevertheless, we preserve a uni ed interface to both programming models to maintain the productivity of computational quantum chemists.

    The ability to identify neuronal damage in the dendritic arbor during HIV-1-associated dementia (HAD) is crucial for designing specific therapies for the treatment of HAD. To study this process, we utilized a computer-based image analysis method to quantitatively assess HIV-1 viral protein gp120 and glutamate-mediated individual neuronal damage in cultured cortical neurons. Changes in the number of neurites, arbors, branch nodes, cell body area, and average arbor lengths were determined and a database was formed (http://dm.ist.unomaha. edu/database.htm). We further proposed a two-class model of multiple criteria linear programming (MCLP) to classify such HIV-1-mediated neuronal dendritic and synaptic damages. Given certain classes, including treatments with brain-derived neurotrophic factor (BDNF), glutamate, gp120 or non-treatment controls from our in vitro experimental systems, we used the two-class MCLP model to determine the data patterns between classes in order to gain insight about neuronal dendritic damages. This knowledge can be applied in principle to the design and study of specific therapies for the prevention or reversal of neuronal damage associated with HAD. Finally, the MCLP method was compared with a well-known artificial neural network algorithm to test for the relative potential of different data mining applications in HAD research.

    We demonstrate a novel strategy of self-assembly to scale up origami structures in two-dimensional (2D) space using multiple origami structures, named "2D DNA jigsaw pieces", with a specially designed shape. For execution of 2D self-assembly along the helical axis (horizontal direction), sequence-programmed tenon and mortise were introduced to promote selective connections via π-stacking interaction, sequence-complementarity, and shape-complementarity. For 2D self-assembly along the helical side (vertical direction), the jigsaw shape-complementarity in the top and bottom edges and the sequence-complementarity of single-stranded overhangs were used. We designed and prepared nine different jigsaw pieces and tried to obtain a 3 × 3 assembly. The proof of concept was obtained by performing the assembly in four different ways. Among them, the stepwise self-assembly from the three vertical trimer assemblies gave the target 2D assembly with ∼35% yield. Finally, the surfaces of jigsaw pieces were decorated with hairpin DNAs to display the letters of the alphabet, and the self-assembled 2D structure displayed the word "DNA JIG SAW" in nanoscale. The method can be expanded to create self-assembled modules carrying various functional molecules for practical applications.

  15. Multiple drug cost containment policies in Michigan's Medicaid program saved money overall, although some increased costs.

    Michigan's Medicaid program implemented four cost containment policies--preferred drug lists, joint and multistate purchasing arrangements, and maximum allowable cost--during 2002-04. The goal was to control growth of drug spending for beneficiaries who were enrolled in both Medicaid and Medicare and taking antihypertensive or antihyperlipidemic prescription drugs. We analyzed the impact of each policy while holding the effect of all other policies constant. Preferred drug lists increased both preferred and generic drugs' market share and reduced daily cost--the cost per day for each prescription provided to a beneficiary. In contrast, the maximum allowable cost policy increased daily cost and was the only policy that did not generate cost savings. The joint and multistate arrangements did not affect daily cost. Despite these policy trade-offs, the cumulative effect was a 10 percent decrease in daily cost and a total cost savings of $46,195 per year. Our findings suggest that policy makers need to evaluate the impact of multiple policies aimed at restraining drug spending, and further evaluate the policy trade-offs, to ensure that scarce public dollars achieve the greatest return for money spent.

  16. Using stochastic dual dynamic programming in problems with multiple near-optimal solutions

    NASA Astrophysics Data System (ADS)

    Rougé, Charles; Tilmant, Amaury

    2016-05-01

    Stochastic dual dynamic programming (SDDP) is one of the few algorithmic solutions available to optimize large-scale water resources systems while explicitly considering uncertainty. This paper explores the consequences of, and proposes a solution to, the existence of multiple near-optimal solutions (MNOS) when using SDDP for mid or long-term river basin management. These issues arise when the optimization problem cannot be properly parametrized due to poorly defined and/or unavailable data sets. This work shows that when MNOS exists, (1) SDDP explores more than one solution trajectory in the same run, suggesting different decisions in distinct simulation years even for the same point in the state-space, and (2) SDDP is shown to be very sensitive to even minimal variations of the problem setting, e.g., initial conditions—we call this "algorithmic chaos." Results that exhibit such sensitivity are difficult to interpret. This work proposes a reoptimization method, which simulates system decisions by periodically applying cuts from one given year from the SDDP run. Simulation results obtained through this reoptimization approach are steady state solutions, meaning that their probability distributions are stable from year to year.

  17. A Mixed Integer Linear Program for Solving a Multiple Route Taxi Scheduling Problem

    Aircraft movements on taxiways at busy airports often create bottlenecks. This paper introduces a mixed integer linear program to solve a Multiple Route Aircraft Taxi Scheduling Problem. The outputs of the model are in the form of optimal taxi schedules, which include routing decisions for taxiing aircraft. The model extends an existing single route formulation to include routing decisions. An efficient comparison framework compares the multi-route formulation and the single route formulation. The multi-route model is exercised for east side airport surface traffic at Dallas/Fort Worth International Airport to determine if any arrival taxi time savings can be achieved by allowing arrivals to have two taxi routes: a route that crosses an active departure runway and a perimeter route that avoids the crossing. Results indicate that the multi-route formulation yields reduced arrival taxi times over the single route formulation only when a perimeter taxiway is used. In conditions where the departure aircraft are given an optimal and fixed takeoff sequence, accumulative arrival taxi time savings in the multi-route formulation can be as high as 3.6 hours more than the single route formulation. If the departure sequence is not optimal, the multi-route formulation results in less taxi time savings made over the single route formulation, but the average arrival taxi time is significantly decreased.

    The incorporation of the multiple mini-interview (MMI) into the postgraduate year 1 (PGY1) pharmacy residency program selection process was evaluated. Four MMI stations evaluating the highest-rated nonacademic attributes of prospective residents (critical thinking, teamwork, ethical reasoning and integrity, and communication and interpersonal skills) were incorporated into the traditional PGY1 residency interview process at an academic medical center. After completion of the interview, candidates and interviewers were surveyed regarding their perceptions of the refined interview process. Data regarding scores on various components of the applicant profile were also compared for significant correlations. Descriptive statistics were calculated for questionnaire responses and individual components of candidate profiles. Pearson's correlation coefficients were calculated between MMI score, traditional interview score, age, grade point average, application score, college of pharmacy rank, and final candidate rank (subjective score). A total of 38 candidates were interviewed, 37 of whom completed the postinterview survey. Candidates agreed that the MMI allowed them to convey their abilities effectively; however, they disagreed that it was more effective than traditional interviews. Candidates did not agree that the MMI caused less anxiety than traditional interviews. All 15 interviewers completed the postinterview survey and believed that the MMI effectively evaluated soft skills and that the MMI was more effective than traditional interviews in assessing candidates' abilities, skills, and thought processes. The use of the MMI in a PGY1 pharmacy residency applicant selection process appeared to be well accepted by both candidates and interviewers and likely assesses different attributes than do traditional interview techniques.

  20. Switching of metabolic programs in response to light availability is an essential function of the cyanobacterial circadian output pathway

    PubMed Central

    Puszynska, Anna M; O'Shea, Erin K

    2017-01-01

    The transcription factor RpaA is the master regulator of circadian transcription in cyanobacteria, driving genome-wide oscillations in mRNA abundance. Deletion of rpaA has no effect on viability in constant light conditions, but renders cells inviable in cycling conditions when light and dark periods alternate. We investigated the mechanisms underlying this viability defect, and demonstrate that the rpaA- strain cannot maintain appropriate energy status at night, does not accumulate carbon reserves during the day, and is defective in transcription of genes crucial for utilization of carbohydrate stores at night. Reconstruction of carbon utilization pathways combined with provision of an external carbon source restores energy charge and viability of the rpaA- strain in light/dark cycling conditions. Our observations highlight how a circadian output pathway controls and temporally coordinates essential pathways in carbon metabolism to maximize fitness of cells facing periodic energy limitations.

    Background Cognitive impairment is a common feature in multiple sclerosis (MS) and may have a substantial impact on quality of life. Evidence about the effectiveness of neuropsychological rehabilitation is still limited, but current data suggest that computer-assisted cognitive training improves cognitive performance. Objective The objective of this study was to evaluate the efficacy of combined computer-assisted training supported by home-based neuropsychological training to improve attention, processing speed, memory and executive functions during 3 consecutive months. Methods In this randomized controlled study blinded for the evaluators, 62 MS patients with clinically stable disease and mild-to-moderate levels of cognitive impairment were randomized to receive a computer-assisted neuropsychological training program (n=30) or no intervention (control group [CG]; n=32). The cognitive assessment included the Brief Repeatable Battery of Neuropsychological Test. Other secondary measures included subjective cognitive impairment, anxiety and depression, fatigue and quality of life measures. Results The treatment group (TG) showed significant improvements in measures of verbal memory, working memory and phonetic fluency after intervention, and repeated measures analysis of covariance revealed a positive effect in most of the functions. The control group (CG) did not show changes. The TG showed a significant reduction in anxiety symptoms and significant improvement in quality of life. There were no improvements in fatigue levels and depressive symptoms. Conclusion Cognitive intervention with a computer-assisted training supported by home training between face-to-face sessions is a useful tool to treat patients with MS and improve functions such as verbal memory, working memory and phonetic fluency.

    2008-06-01

    Learning to question is essential for determining pathways of conservation and development in southwestern Amazonia during a time of rapid global environmental change. Teaching such an approach in graduate science programs in regional universities can be done using play-acting and simulation exercises. Multiple working hypotheses help students learn to question their own research results and expert witnesses. The method of successive approximations enables students to question the results of complex calculations, such as estimates of forest biomass. Balloons and rolls of toilet paper provide means of questioning two-dimensional representations of a three-dimensional Earth and the value of pi. Generation of systematic errors can illustrate the pitfalls of blind acceptance of data. While learning to question is essential, it is insufficient by itself; students must also learn how to be solutionologists in order to satisfy societal demands for solutions to environmental problems. A little irreverence can be an excellent didactic tool for helping students develop the skills necessary to lead conservation and development efforts in the region.

    The development of a process to select the best residents for training programs is challenging. There is a paucity of literature to support the implementation of an evidence-based approach or even best practice for program directors and selection committees. Although assessment of traditional academic markers such as clerkship grades and licensing examination scores can be helpful, these measures typically fail to capture performance in the noncognitive domains of medicine. In the specialty of physical medicine and rehabilitation, physician competencies such as communication, health advocacy, and managerial and collaborative skills are of particular importance, but these are often difficult to evaluate in admission interviews. Recent research on admission processes for medical schools has demonstrated reliability and validity of the "multiple mini-interview." The objective of our project was to develop and evaluate the multiple mini-interview for a physical medicine and rehabilitation residency training program, with a focus on assessment of the noncognitive physician competencies. We found that the process was feasible, time efficient, and cost-efficient and that there was good interrater reliability. The multiple mini-interview may be applied to other physical medicine and rehabilitation residency programs. Further research is needed to confirm reliability and determine validity.

    Exercise and leisure activities provide physical and psychosocial benefits to people with multiple sclerosis (MS) and can enhance their quality of life. In Winnipeg, Manitoba, Canada, people with MS have reported barriers to their participation in local MS-specific aquafitness (AF) programs. Therefore, a formal exploration of the accessibility of local AF programs for people with MS was undertaken. The purpose of this phenomenological study was to identify factors that facilitate or impede participation in AF programs by individuals with MS living in Winnipeg. Qualitative data were collected from a total of eight participants through one focus group (n = 7) and one in-depth interview (n = 1). The sample consisted of individuals with MS who were currently participating in AF programming as well as those who were not. Data were audio-recorded and transcribed verbatim, and thematic analysis was completed. Seven themes emerged regarding factors affecting participation in local AF programs. Barriers to participation included inadequate transportation, lack of one-on-one support, environmental inaccessibility, and fears associated with participation in the programs. Facilitators of participation included a knowledgeable instructor and experiencing physical and psychosocial benefits from the program. Information from this study was used locally to advocate for people with MS in order to increase participation in local AF programming.

  13. Ca analysis: An Excel based program for the analysis of intracellular calcium transients including multiple, simultaneous regression analysis☆

    Here I present an Excel based program for the analysis of intracellular Ca transients recorded using fluorescent indicators. The program can perform all the necessary steps which convert recorded raw voltage changes into meaningful physiological information. The program performs two fundamental processes. (1) It can prepare the raw signal by several methods. (2) It can then be used to analyze the prepared data to provide information such as absolute intracellular Ca levels. Also, the rates of change of Ca can be measured using multiple, simultaneous regression analysis. I demonstrate that this program performs equally well as commercially available software, but has numerous advantages, namely creating a simplified, self-contained analysis workflow. PMID:24125908

    The objective was to determine safety and efficacy of health supplements "Beyond Tangy Tangerine," a multivitamin/mineral complex and combination of multivitamin/mineral complex, "Osteofx," a bone healthy supplement and "Ultimate Essential Fatty Acids" in Sprague Dawley rats consuming high-fat diets. Initially a pilot study was conducted which confirmed palatability and acceptability of supplements. In a second study, rats (n = 15/group) were randomized to Control; Multivitamin/mineral complex (2 g/kg BW) or Combination (2 g Multivitamin/mineral complex, 1.5 g Bone healthy supplement and 0.34 g Essential fatty acids/kg BW). No differences were observed in BW change, feed intake, organ weights or bone mineral composition with supplementations compared to control. Multivitamin/mineral complex supplementation decreased abdominal white adipose tissue weights (WAT) (p = .005), total (p = .033) and fat mass (p = .040), plasma IL-6 (p = .016) and ALKP (p = .038) and elevated plasma calcium (p < .001), phosphorus (p = .038), total protein (p = .002), albumin (p = .014) and globulin (p = .018), compared to control. Similarly, combination supplementation reduced WAT (p < .001), total (p = .023) and fat mass (p = .045), plasma triglycerides (p = .018), IL-6 (p = .002) and ALKP (p < .001) with increases in plasma calcium (p = .031), phosphorus (p < .001) compared to control. Results indicate that consuming either supplement can be considered safe and improves overall health by reducing inflammation, abdominal fat mass and plasma triglycerides, as well as promote bone health.

    The Prevention and Reactivation Care Program (PReCaP) provides a novel approach targeting hospital-related functional decline among elderly patients. Despite the high expectations, the PReCaP was not effective in preventing functional decline (ADL and iADL) among older patients. Although elderly PReCaP patients demonstrated slightly better cognitive functioning (Mini Mental State Examination; 0.4 [95% confidence interval (CI) 0.2-0.6]), lower depression (Geriatric Depression Scale 15; -0.9 [95% -1.1 to -0.6]), and higher perceived health (Short-form 20; 5.6 [95% CI 2.8-8.4]) 1 year after admission than control patients, the clinical relevance was limited. Therefore, this study aims to identify factors impacting on the effectiveness of the implementation of the PReCaPand geriatric care 'as usual'. We conducted semi-structured interviews with 34 professionals working with elderly patients in three hospitals, selected for their comparable patient case mix and different levels of geriatric care. Five non-participatory observations were undertaken during multidisciplinary meetings. Patient files (n = 42), hospital protocols, and care plans were screened for elements of geriatric care. Clinical process data were analysed for PReCaP components. The establishment of a geriatric unit and employment of geriatricians demonstrates commitment to geriatric care in hospital A. Although admission processes are comparable, early identification of frail elderly patients only takes place in hosptial A. Furthermore, nursing care in the hospital A geriatric unit excels with regard to maximizing patient independency, an important predictor for hospital-related functional decline. Transfer nurses play a key role in arranging post-discharge geriatric follow-up care. Geriatric consultations are performed by geriatricians, geriatric nurses, and PReCaP case managers in hospital A. Yet hospital B consultative psychiatric nurses provide similar consultation services. The combination of

    These two studies extended technology-aided programs to promote leisure and communication opportunities to a man with cervical spinal cord injury and a post-coma man with multiple disabilities. The studies involved the use of ABAB designs, in which A and B represented baseline and intervention phases, respectively. The programs focused on enabling the participants to activate songs, videos, requests, text messages, and telephone calls. These options were presented on a computer screen and activated through a small pressure microswitch by the man with spinal cord injury and a special touch screen by the post-coma man. To help the latter participant, who had no verbal skills, with requests and telephone calls, series of words and phrases were made available that he could activate in those situations. Data showed that both participants were successful in managing the programs arranged for them. The man with spinal cord injury activated mean frequencies of above five options per 10-min session. The post-coma man activated mean frequencies of about 12 options per 20-min session. Technology-aided programs for promoting leisure and communication opportunities might be successfully tailored to persons with spinal cord injury and persons with post-coma multiple disabilities. Implications for Rehabilitation Technology-aided programs may be critical to enable persons with pervasive motor impairment to engage in leisure activities and communication events independently. Persons with spinal cord injury, post-coma extended brain damage, and forms of neurodegenerative disease, such as amyotrophic lateral sclerosis, may benefit from those programs. The programs could be adapted to the participants' characteristics, both in terms of technology and contents, so as to improve their overall impact on the participants' functioning and general mood.

    Previous studies using mannose-binding lectin (MBL) and complement C4 deficient mice have suggested that the lectin pathway (LP) is not required for the development of inflammatory arthritis in the collagen antibody-induced arthritis (CAIA) model. MBL, ficolins and collectin-11 are key LP pattern recognition molecules that associate with three serine proteases, MASP-1, MASP-2 and MASP-3, and also with two MBL-associated proteins designated sMAP and MAp44. Recent studies have shown that MAp44, an alternatively spliced product of the MASP-1/3 gene, is a competitive inhibitor of the binding of the recognition molecules to all three MASPs. In these studies we examined the effect of treatment of mice with adenovirus (Ad) programmed to express human MAp44 (AdhMAp44) on the development of CAIA. AdhMAp44 and Ad programming Green fluorescent protein (AdGFP) expression were injected intraperitoneally in C57BL/6 wild-type mice prior to the induction of CAIA. AdhMAp44 significantly reduced the clinical disease activity score (CDA) by 81% compared to mice injected with AdGFP. Similarly, histopathologic injury scores for inflammation, pannus, cartilage and bone damage, as well as C3 deposition in the cartilage and synovium, were significantly reduced by AdhMAp44 pretreatment. Mice treated with AdmMAp44, programming expression of mouse MAp44, also showed significantly decreased CDA and histopathologic injury scores. Additionally, administration of AdhMAp44 significantly diminished the severity of Ross River Virus-induced arthritis, a LP-dependent model. Our study provides conclusive evidence that an intact complement LP is essential to initiate CAIA, and that MAp44 may be an appropriate treatment for inflammatory arthritis. PMID:25070856

    Technology-aided programs have been reported to help persons with disabilities develop adaptive responding and control problem behavior/posture. This study assessed one such program in which choice of stimulus events was used as adaptive responding for three adults with multiple disabilities. A computer system presented the participants stimulus samples. For each sample, they could perform a choice response (gaining access to the related stimulus whose length they could extend) or abstain from responding (making the system proceed to the next sample). Once choice responding had strengthened, the program also targeted the participants' problem posture (i.e., head and trunk forward bending). The stimulus exposure gained with a choice response was interrupted if the problem posture occurred. All three participants successfully (a) managed choice responses and access to preferred stimuli and (b) gained postural control (i.e., reducing the problem posture to very low levels). The practical implications of those results are discussed.

The program works by solving relaxation theory equations for the given system, and it can be useful in order to plan the ideal conditions to set up specific experiments or to give a physical interpretation of experimental results. The program allows to independently follow the dependence of individual coherences and relaxation rates as a function of up to 50 parameters regarding the physical properties of the system under investigation, sample conditions and instrumental setup making it an helpful tool also for teaching purposes.

  12. Factors influencing the implementation of a lifestyle counseling program in patients with venous leg ulcers: a multiple case study

    PubMed Central

    2012-01-01

    Background Implementation of lifestyle interventions in patient care is a major challenge. Understanding factors that influence implementation is a first step in programs to enhance uptake of these interventions. A lifestyle-counseling intervention, Lively Legs, delivered by trained nurses, can effectively improve the lifestyle in patients with venous leg ulcers. The aim of this study was to identify factors that hindered or facilitated implementation of this intervention in outpatient dermatology clinics and in home care. Methods A mixed-methods multiple case study in five purposefully selected healthcare settings in the Netherlands was conducted. Measurements to identify influencing factors before and after implementation of Lively Legs included interviews, focus groups, questionnaires, and nurses’ registration. Analyses focused on qualitative data as the main data source. All data were compared across multiple cases to draw conclusions from the study as a whole. Results A total of 53 patients enrolled in the Lively Legs program, which was delivered by 12 trained nurses. Barriers for implementation were mainly organizational. It was difficult to effectively organize reaching and recruiting patients for the program, especially in home care. Main barriers were a lack of a standardized healthcare delivery process, insufficient nursing time, and a lack of motivated nurses to deliver the program. Facilitating factors were nurse-driven coordination of care and a standardized care process to tie Lively Legs into, as this resulted in better patient recruitment and better program implementation. Conclusions This study identified a range of factors influencing the implementation of a lifestyle-counseling program, mainly related to the organization of healthcare. Using a case study method proved valuable in obtaining insight into influencing factors for implementation. This study also shed light on a more general issue, which is that leg ulcer care is often fragmented

    Pay for performance (P4P) has been used as a strategy to improve quality for patients with chronic illness. Little was known whether care provided to individuals with multiple chronic conditions in a P4P program were cost-effective. This study investigated cost effectiveness of a diabetes P4P program for caring patients with diabetes alone (DM alone) and diabetes with comorbid hypertension and hyperlipidemia (DMHH) from a single payer perspective in Taiwan. Analyzing data using population-based longitudinal databases, we compared costs and effectiveness between P4P and non-P4P diabetes patient groups in two cohorts. Propensity score matching (PSM) was used to match comparable control groups for intervention groups. Outcomes included life-years, quality-adjusted life-years (QALYs), program intervention costs, cost-savings and incremental cost-effectiveness ratios (ICERs). QALYs for P4P patients and non-P4P patients were 2.80 and 2.71 for the DM alone cohort and 2.74 and 2.66 for the DMHH patient cohort. The average incremental intervention costs per QALYs was TWD$167,251 in the DM alone cohort and TWD$145,474 in the DMHH cohort. The average incremental all-cause medical costs saved by the P4P program per QALYs were TWD$434,815 in DM alone cohort and TWD$506,199 in the DMHH cohort. The findings indicated that the P4P program for both cohorts were cost-effective and the resulting return on investment (ROI) was 2.60:1 in the DM alone cohort and 3.48:1 in the DMHH cohort. We conclude that the diabetes P4P program in both cohorts enabled the long-term cost-effective use of resources and cost-savings, especially for patients with multiple comorbid conditions.

    Physical and technical details of the GOL-NB project are presented. GOL-NB is a medium-scale multiple-mirror trap that is under development in the Budker Institute, Novosibirsk, Russia. This device will be created in several years as a deep conversion of the existing GOL-3 facility. It will consist of a central trap with two 0.75 MW neutral beams, two multiple-mirror solenoids, two expander tanks and a plasma gun that creates the start plasma. The central trap with the neutral beam injection-heated plasma is a compact gas-dynamic system. The multiple-mirror sections should decrease the power and particle losses along the magnetic field. The confinement improvement factor depends on plasma parameters and on the magnetic configuration in the multiple mirrors. The main physical task of GOL-NB is direct demonstration of the performance of multiple-mirror sections that will change equilibrium plasma parameters in the central trap. In this paper we discuss results of the scenario modeling and progress in the hardware.

    Background: This pilot study determined the feasibility of a specifically designed 8-week yoga program for people with moderate multiple sclerosis (MS)–related disability. We explored the program's effect on quality of life (QOL) and physical and mental performance. Methods: We used a single-group design with repeated measurements at baseline, postintervention, and 8-week follow-up. Feasibility was examined through cost, recruitment, retention, attendance, and safety. Outcomes included the Multiple Sclerosis Quality of Life Inventory (MSQLI), 12-item Multiple Sclerosis Walking Scale (MSWS-12), Timed 25-Foot Walk test (T25FW), 6-Minute Walk Test (6MWT), Nine-Hole Peg Test (NHPT), Five-Times Sit-to-Stand Test (FTSTS), Multidirectional Reach Test (MDRT), maximum expiratory pressure, and Paced Auditory Serial Addition Test-3″ (PASAT-3″). Results: Fourteen participants completed the study. The program was feasible. There were significant main effects on the 36-item Short Form Health Status Survey Mental Component Summary (SF-36 MCS), Modified Fatigue Impact Scale (MFIS), Bladder Control Scale (BLCS), Perceived Deficits Questionnaire (PDQ), Mental Health Inventory (MHI), MSWS-12, T25FW, NHPT, PASAT-3″, 6MWT, FTSTS, and MDRT-Back. Improvements were found on the SF-36 MCS, MFIS, BLCS, PDQ, MHI, and MSWS-12 between baseline and postintervention. The effect on PDQ persisted at follow-up. Improvements were found on the T25FW, NHPT, 6MWT, FTSTS, and MDRT-Back between baseline and postintervention that persisted at follow-up. The PASAT-3″ did not change between baseline and postintervention but did between postintervention and follow-up. Conclusions: The yoga program was safe and feasible. Improvements in certain measures of QOL and performance were seen at postintervention and follow-up. PMID:28243184

    Examination of the effect of the himA and himD mutants of E. coli on the maintenance of plasmid R6K has revealed that the gamma origin-containing replicons cannot be established in any of the mutants deficient in the production of E. coli Integration Host Factor (IHF). Contrary, the R6K derivatives containing other origins of the plasmid (alpha and/or beta) replicate in a host lacking functional IHF protein. We show that IHF protein binds specifically to a segment of the replication region which is essential for the activity of all three R6K origins. Mapping the IHF binding sequence with neocarzinostatin showed that the protein protects three segments of the origin: two strong binding sites reside within an AT-rich block, while the third, considerably weaker site is separated from the other two by a cluster of the seven 22 bp direct repeats. These seven repeats have been shown previously to bind the R6K-encoded initiator protein pi. We also demonstrate that the establishment of pi-origin complexes prior to IHF addition prevents the binding of the IHF protein to the gamma origin. The binding sequences of IHF and pi proteins do not overlap, therefore, we propose that the binding of pi protein alters the structure of the DNA and thereby prevents the subsequent binding of IHF protein.

    Background: Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease of the central nervous system. Fatigue is a common and disabling symptom, often causing decreased quality of life, social withdrawal, and unemployment. We developed and studied the feasibility of a cognitive-behavioral group intervention to manage fatigue in MS. We aimed to integrate the concepts of cognitive-behavioral therapy and evidence-based patient information. Methods: We conducted patient interviews and a focus group to assess patients' interest in and need for fatigue self-management training and developed the program accordingly. The program consists of six 90-minute modules, which were structured with the use of moderation cards, helping to guarantee treatment fidelity. The program was tested on three pilot groups (N = 16) in a rehabilitation center. Fatigue, depression, and coping self-efficacy were assessed at baseline and after the intervention. Acceptance and general satisfaction with the program were also evaluated. Results: Patient interviews elicited different characteristics of fatigue, suggesting that patients had different requirements. The program was very acceptable to patients. Pre-post assessments of the pilot study showed significantly improved scores on the Coping Self-Efficacy Scale (P = .013) but not on the Fatigue Scale for Motor and Cognitive Functions and the 30-item Inventory of Depressive Symptomatology. Conclusions: These preliminary results suggest that this program is a feasible cognitive-behavioral group training program that may improve coping self-efficacy and has the potential to subsequently reduce fatigue. The next step is evaluation of the program in a randomized controlled trial. PMID:27252600

  20. A non-linear regression analysis program for describing electrophysiological data with multiple functions using Microsoft Excel.

    PubMed

    Brown, Angus M

    2006-04-01

    The objective of this present study was to demonstrate a method for fitting complex electrophysiological data with multiple functions using the SOLVER add-in of the ubiquitous spreadsheet Microsoft Excel. SOLVER minimizes the difference between the sum of the squares of the data to be fit and the function(s) describing the data using an iterative generalized reduced gradient method. While it is a straightforward procedure to fit data with linear functions, and we have previously demonstrated a method of non-linear regression analysis of experimental data based upon a single function, it is more complex to fit data with multiple functions, usually requiring specialized expensive computer software. In this paper we describe an easily understood program for fitting experimentally acquired data, in this case the stimulus-evoked compound action potential from the mouse optic nerve, with multiple Gaussian functions. The program is flexible and can be applied to describe data with a wide variety of user-input functions.

  1. Essential tremor.

    Essential tremor, including the juvenile and senile variations, may be a result of a disorder of the servomechanism that controls physiologic tremor. Hands and arms are affected most commonly, and the tremor can vary in amplitude as well as frequency. Long-term treatment with propranolol has been helpful for some patients, although older patients are less likely to benefit. Other drugs and behaviour modification therapy have been less successful. Surgical treatment is effective but should probably be reserved for severe cases. An effective instrument for measuring the subjective and objective aspects of the tremor is still needed, as is an effective long-term method of treatment. PMID:7018658

    To evaluate technology-assisted programs to help a man with pervasive motor disabilities and an adolescent with multiple disabilities manage the use of a radio and a special messaging system, respectively. The technology for the man (Study I) involved a modified radio device, an electronic control unit, an amplified MP3 player with verbal questions about radio operations (changes), and an optic microswitch. This allowed the man to respond to the questions and carry out operations through minimal chin movement. The technology for the adolescent (Study II) involved a net-book computer fitted with specifically designed software, a global system for mobile communication (GSM) modem, and an optic microswitch. This allowed the adolescent to select the persons to whom he wanted to send messages and the messages to send them, and to listen to messages sent to him. The data showed that both programs were effective, with the two participants learning to use the radio and the messaging system, respectively. Technology-assisted programs may represent useful tools for providing persons with pervasive and multiple disabilities leisure and communication opportunities.

    People with multiple sclerosis (MS) fall frequently. In 2011, the National Multiple Sclerosis Society launched a multifactorial fall-prevention group exercise and education program, Free From Falls (FFF), to prevent falls in MS. The objective of this study was to assess the impact of participation in the FFF program on balance, mobility, and falls in people with MS. This was a retrospective evaluation of assessments from community delivery of FFF. Changes in Activities-specific Balance Confidence scale scores, Berg Balance Scale scores, 8-foot Timed Up and Go performance, and falls were assessed. A total of 134 participants completed the measures at the first and last FFF sessions, and 109 completed a 6-month follow-up assessment. Group mean scores on the Activities-specific Balance Confidence scale (F1,66 = 17.14, P < .05, η(2) = 0.21), Berg Balance Scale (F1,68 = 23.39, P < .05, η(2) = 0.26), and 8-foot Timed Up and Go (F1,79 = 4.83, P < .05, η(2) = 0.06) all improved significantly from the first to the last session. At the 6-month follow-up, fewer falls were reported (χ(2) [4, N = 239] = 10.56, P < .05, Phi = 0.21). These observational data suggest that the FFF group education and exercise program improves balance confidence, balance performance, and functional mobility and reduces falls in people with MS.

  10. Multiple ART Programs Create a Dilemma for Providers to Monitor ARV Adherence in Uganda

    Background: Increased availability and accessibility of antiretroviral therapy (ART) has improved the length and quality of life amongst people living with HIV/AIDS. This has changed the landscape for care from episodic to long-term care that requires more monitoring of adherence. This has led to increased demand on human resources, a major problem for most ART programs. This paper presents experiences and perspectives of providers in ART facilities, exploring the organizational factors affecting their capacity to monitor adherence to ARVs. Methods: From an earlier survey to test adherence indicators and rank facilities as good, medium or poor adherence performances, six facilities were randomly selected, two from each rank. Observations on facility set-up, provider-patient interactions and key informant interviews were carried out. The strengths, weaknesses, opportunities and threats identified by health workers as facilitators or barriers to their capacity to monitor adherence to ARVs were explored during group discussions. Results: Findings show that the performance levels of the facilities were characterized by four different organizational ART programs operating in Uganda, with apparent lack of integration and coordination at the facilities. Of the six facilities studied, the two high adherence performing facilities were Non-Governmental Organization (NGO) programs, while facilities with dual organizational programs (Governmental/NGO) performed poorly. Working conditions, record keeping and the duality of programs underscored the providers’ capacity to monitor adherence. Overall 70% of the observed provider-patient interactions were conducted in environments that ensured privacy of the patient. The mean performance for record keeping was 79% and 50% in the high and low performing facilities respectively. Providers often found it difficult to monitor adherence due to the conflicting demands from the different organizational ART programs. Conclusion

  11. Studies on the factors essential to the initiation and maintenance of multiplication of psittacosis virus (6BC strain) in deficient cells in tissue culture.

    The growth of psittacosis virus (6BC) was studied in cultures of minced whole chick embryo tissue maintained in either Hanks-Simms solution or Hanks's balanced salt solution (BSS), and in neither medium could sustained, long-term virus growth take place. Addition of beef embryo extract (BEE) to cultures at a time when virus multiplication was declining reversed this general trend and resulted in greater virus growth. This virus-stimulating action of BEE was only partially diminished by colchicine, a mitotic inhibitor, indicating that the action of BEE was not due entirely to the development of a larger population of cells as a result of its enhancement of cell proliferation. Chick embryo tissue cultivated for 13 days in BSS prior to infection lost its ability to support the growth of psittacosis virus, but this capacity could be restored by the addition of BEE, alone or with colchicine, at the time of infection. A significant amount of virus was adsorbed to tissue in BSS alone, indicating that the failure of virus to grow in depleted tissue maintained only in BSS after infection was not due entirely to failure of virus to attach to and invade the cells. It was found that an ultrafiltrate and a dialysate of BEE contained the major part of the stimulating capacity of the whole extract, indicating that the active materials were substances of low molecular weights. Autoclaved lactalbumin hydrolysate was an active stimulator, suggesting that the materials responsible for its activity were relatively heat-stable. Since a chemically defined medium (Parker 199) was equally effective in stimulating viral growth, it should be possible eventually to define the chemical nature of the virus stimulators. The implications of the findings are discussed with special reference to their application in the study of tissue tropisms and of latency in viral infections of cells.

    Elevated HPV infection rates have been described in HIV-positive males, placing these subjects at high risk of anal neoplasia. Bivalent, quadrivalent, and nonavalent vaccines to prevent HPV infection have been developed, and recently proposed for gender-neutral immunization programs. In order to estimate the benefit that could be obtained by vaccination of HIV-positive men who have sex with men (MSM), we aimed at describing the frequency of multiple and vaccine-targeted HPV infections in MSM enrolled in an anal cancer screening program. The anal cancer screening program was conducted between July 2009 and October 2012. Mucosal anal samples were tested for HPV DNA using MY09/MY11 PCR primers and, if positive, genotyped using the CLART2HPV Clinical Array (35HPV types). A total of 220 MSM were screened and 88.6% were positive for HPV DNA: in 86.5% at least one high-risk (HR) type was found and in 13% only low-risk (LR) HPV were found. Multiple infections accounted for 84.5% of HPV DNA-positive cases and overall 160 different HPV genotype combinations were recognized (only three combinations were detected in more than one patient each). Based on strain coverage, at least one vaccine-targeted HPV type was found in 38.9%, 64%, and 78.4% of cases when considering bivalent, quadrivalent and nonavalent vaccines, respectively. At least one HR vaccine-targeted strain was found in 39% of MSM for bivalent and quadrivalent vaccines, and in 64% of cases for nonavalent prevention. Anal HPV infections in unvaccinated mostly HIV-infected MSM are highly prevalent. The majority of this population has multiple infections with an extremely heterogeneous number of genotype combinations. The nonavalent vaccine could theoretically have prevented a minimum of one HR HPV type in two thirds of subjects. Copyright © 2015 Elsevier B.V. All rights reserved.

    Multiple-Mini Interviews (MMIs) were used to assess professional attributes of candidates seeking admission to an occupational therapy professional entry-level master's program. Candidates and interviewers were invited to complete a questionnaire comprised of quantitative and open-ended questions following the MMIs. The MMIs were perceived to be fair, enjoyable, and capable of capturing professional attributes. Descriptive analysis of candidates' data revealed perceptions regarding logistics, interview station content, process, and interviewers. Interviewers commented on the positive and challenging aspects of the scenarios and the MMI process. Admissions committees need to consider several logistical, content, and process issues when designing and implementing MMIs as a selection tool.

    Monitoring programs have the potential to identify population declines and differentiate among the possible cause(s) of these declines. Recent criticisms regarding the design of monitoring programs have highlighted a failure to clearly state objectives and to address detectability and spatial sampling issues. Here, we incorporate these criticisms to design an efficient monitoring program whose goals are to determine environmental factors which influence the current distribution and measure change in distributions over time for a suite of amphibians. In designing the study we (1) specified a priori factors that may relate to occupancy, extinction, and colonization probabilities and (2) used the data collected (incorporating detectability) to address our scientific questions and adjust our sampling protocols. Our results highlight the role of wetland hydroperiod and other local covariates in the probability of amphibian occupancy. There was a change in overall occupancy probabilities for most species over the first three years of monitoring. Most colonization and extinction estimates were constant over time (years) and space (among wetlands), with one notable exception: local extinction probabilities for Rana clamitans were lower for wetlands with longer hydroperiods. We used information from the target system to generate scenarios of population change and gauge the ability of the current sampling to meet monitoring goals. Our results highlight the limitations of the current sampling design, emphasizing the need for long-term efforts, with periodic re-evaluation of the program in a framework that can inform management decisions.

    Preparing a Perimeter Air Monitoring Plan that provides the essential information and methods of evaluation needed to assure that the health of the surrounding community is adequately protected and adapting currently existing Cal/OSHA regulations to be relevant to the protection of workers at sites involving the excavation of Naturally Occurring Asbestos (NOA) is oftentimes challenging in California. Current guidelines regarding what constitutes an effective air monitoring program are often lacking in details regarding what should be sampled and analyzed to characterize a site and what evaluation techniques should be applied to process the results of monitoring, and the current Cal/OSHA asbestos related regulations regarding worker protection are for the most part largely pertinent to the abatement of asbestos in buildings. An overview of the essential components of an effective Baseline and Perimeter Air Monitoring Plan will be presented that includes a brief discussion of the various asbestos types and fiber sizes that may need to be considered, possible approachs for evaluating temporal and spatial variability, review of selected site boundary target concentrations, and consideration of the potential for airborne dust and soil containing asbestos (and other contaminants) to migrate and accumulate offsite eventually contributing to "background creep" --the incremental increase of overall airborne asbestos concentrations in the areas surrounding the site due to the re-entrainment of asbestos from the settled dust and/or transported soil. In addition to the above, the current Cal/OSHA asbestos regulations related to worker protection will be briefly discussed with respect to their relevancy at NOA sites with an overview of the adaptations to the regulations that were developed as a result of some fairly lengthy discussions with representatives of Cal/OSHA. These adaptations include, among other things, defining how regulated areas (asbestos concentrations over 1

    In order to meet the needs of therapy of multiple sclerosis (MS) new immune therapies with a user-friendly application and better effectiveness together with good tolerability are necessary. With respect to its potential to improve MS therapy, patients with a high medical need were given access to Fingolimod even before marketing approval. Therefore, a compassionate use program unique in the field of MS was initiated. In total 137 centers participated (75 % outpatient neurologists and 25 % hospitals). Within 19 weeks 135 patients were enrolled to receive Fingolimod. The patients in the compassionate use program can be representatively described as showing hardly controllable disease activity and progression with currently available, often poorly tolerated therapy. The compassionate use program for these patients offered better control of the disease with Fingolimod. The adverse events were as expected. The Fingolimod compassionate use program demonstrated the need for this new therapeutic option. Patients who were not yet sufficiently treated were provided with an effective therapy with a good safety profile and a user-friendly administration form.

    In this single blind randomized controlled trial, we examined the effect of a virtual reality-based training on gait of people with multiple sclerosis. Twenty-five individuals with multiple sclerosis with mild to moderate disability were randomly assigned to either the control group (n = 11) or the experimental group (n = 14). The subjects in the control group received treadmill training. Subjects in the experimental group received virtual reality based treadmill training. Clinical measures and gait parameters were evaluated. Subjects in both the groups significantly improved the walking endurance and speed, cadence and stride length, lower limb joint ranges of motion and powers, during single and dual task gait. Moreover, subjects in the experimental group also improved balance, as indicated by the results of the clinical motor tests (p < 0.05). Between-group comparisons revealed that the experimental group improved significantly more than control group in hip range of motion and hip generated power at terminal stance at post-training. Our results support the perceived benefits of training programs that incorporate virtual reality to improve gait measures in individuals with multiple sclerosis. Implication of rehabilitation Gait deficits are common in multiple sclerosis (85%) and worsen during dual task activities. Intensive and progressive treadmill training, with and without virtual reality, is effective on dual task gait in persons with multiple sclerosis. Virtual reality-based treadmill training requiring obstacle negotiation increases the range of motion and the power generated at the hip, consequently allowing longer stride length and, consequently, higher gait speed.

    Three-dimensional (3D) vessel data from CTA or MRA are not always available prior to or during endovascular interventional procedures, whereas multiple 2D projection angiograms often are. Unfortunately, patient movement, table movement, and gantry sag during angiographic procedures can lead to large errors in gantry-based imaging geometries and thereby incorrect 3D. Therefore, we are developing methods for combining vessel data from multiple 2D angiographic views obtained during interventional procedures to provide 3D vessel data during these procedures. Multiple 2D projection views of carotid vessels are obtained, and the vessel centerlines are indicated. For each pair of views, endpoints of the 3D centerlines are reconstructed using triangulation based on the provided gantry geometry. Previous investigations indicated that translation errors were the primary source of error in the reconstructed 3D. Therefore, the errors in the translations relating the imaging systems are corrected by minimizing the L1 distance between the reconstructed endpoints, after which the 3D centerlines are reconstructed using epipolar constraints for every pair of views. Evaluations were performed using simulations, phantom data, and clinical cases. In simulation and phantom studies, the RMS error decreased from 6.0 mm obtained with biplane approaches to 0.5 mm with our technique. Centerlines in clinical cases are smoother and more consistent than those calculated from individual biplane pairs. The 3D centerlines are calculated in about 2 seconds. These results indicate that reliable 3D vessel data can be generated for treatment planning or revision during interventional procedures.

    1993-10-01

    Assessing the contributions of individual components in multi-component interventions poses complex challenges for prevention researchers. We review the strengths and weaknesses of designs and analyses that may be useful in answering three questions: (1) Is each of the individual components contributing to the outcome? (2) Is the program optimal? and (3), Through what processes are the components of the program achieving their effects? Factorial and fractional factorial designs in which a systematically selected portion of all possible treatment combinations is implemented are used to address question 1. Response surface designs in which each component is quantitatively scaled are explored in relation to question 2. Mediational analysis, a hybrid of experimental and correlational approaches, is considered in relation to question 3. Design enhancements are offered that may further strengthen some of these techniques. These techniques offer promise of enhancing both the basic science and applied science contributions of prevention research.

    2010-01-01

    A peer teaching program was implemented to alleviate the problem of a limited number of lab instructors attempting to teach large numbers of students in two different undergraduate microbiology lab courses. The benefit of having peer teachers was immediately obvious to the lab instructors, faculty and staff who were responsible for conducting the labs, but it was soon evident that there were also benefits for everyone else involved in the program. The students enrolled in the labs reported that having peer teachers in the lab enhanced their learning, and they felt comfortable receiving help from a peer teacher who had recently completed the course.

    As demand for improved energy efficiency in homes increases, builders need information on the latest findings in building science, rapidly ramping-up energy codes, and technical requirements for labeling programs. The Building America Solution Center is a Department of Energy (DOE) website containing hundreds of expert guides designed to help residential builders install efficiency measures in new and existing homes. Builders can package measures with other media for customized content. Website content provides technical support to market transformation programs such as ENERGY STAR and has been cloned and adapted to provide content for the Better Buildings Residential Program. The Solution Center uses the Drupal open source content management platform to combine a variety of media in an interactive manner to make information easily accessible. Developers designed a unique taxonomy to organize and manage content. That taxonomy was translated into web-based modules that allow users to rapidly traverse structured content with related topics, and media. We will present information on the current design of the Solution Center and the underlying technology used to manage the content. The paper will explore development of features, such as “Field Kits” that allow users to bundle and save content for quick access, along with the ability to export PDF versions of content. Finally, we will discuss development of an Android based mobile application, and a visualization tool for interacting with Building Science Publications that allows the user to dynamically search the entire Building America Library.

    A peer teaching program was implemented to alleviate the problem of a limited number of lab instructors attempting to teach large numbers of students in two different undergraduate microbiology lab courses. The benefit of having peer teachers was immediately obvious to the lab instructors, faculty and staff who were responsible for conducting the labs, but it was soon evident that there were also benefits for everyone else involved in the program. The students enrolled in the labs reported that having peer teachers in the lab enhanced their learning, and they felt comfortable receiving help from a peer teacher who had recently completed the course. The peer teachers discovered that they gained valuable experience and confidence while teaching other students, and they appreciated the chance to gain hands-on experience. The lab instructors received the qualified help they needed in order to give more individual attention to the large numbers of students in the labs. The feedback from this program has been positive from everyone involved. PMID:23653707

    2013-10-01

    This article considers the design of cross-docking systems under uncertainty in a model that consists of two phases: (1) a strategic-based decision-making process for selecting the location of cross-docks to operate, and (2) an operational-based decision-making process for vehicle routing scheduling with multiple cross-docks. This logistic system contains three echelons, namely suppliers, cross-docks and retailers, in an uncertain environment. In the first phase, a new multi-period cross-dock location model is introduced to determine the minimum number of cross-docks among a set of location sites so that each retailer demand should be met. Then, in the second phase, a new vehicle routing scheduling model with multiple cross-docks is formulated in which each vehicle is able to pickup from or deliver to more than one supplier or retailer, and the pickup and delivery routes start and end at the corresponding cross-dock. This article is the first attempt to introduce an integrated model for cross-docking systems design under a fuzzy environment. To solve the presented two-phase mixed-integer programming (MIP) model, a new fuzzy mathematical programming-based possibilistic approach is used. Furthermore, experimental tests are carried out to demonstrate the effectiveness of the presented model. The computational results reveal the applicability and suitability of the developed fuzzy possibilistic two-phase model in a variety of problems in the domain of cross-docking systems.

    These two studies were aimed at assessing technology-aided programs to help persons with multiple disabilities engage in basic occupation or work activities. Specifically, Study I focused on teaching two participants (an adolescent and an adult) with low vision or total blindness, severe/profound intellectual disabilities, and minimal object interaction to engage in constructive object-manipulation responses. The technology monitored their responses and followed them with brief stimulation periods automatically. Study II focused on teaching three adults with deafness, severe visual impairment, and profound intellectual disabilities to perform a complex activity, that is, to assemble a five-component water pipe. The technology regulated (a) light cues to guide the participants through the workstations containing single pipe components and the carton for completed pipes and (b) stimulation events. The results of both studies were positive. The participants of Study I showed consistent and independent engagement in object-manipulation responses. The participants of Study II showed consistent and independent pipe assembling performance. General implications of the two programs and the related technology packages for intervention with persons with multiple disabilities are discussed.

    Balance and mobility impairments are common in individuals with multiple sclerosis (MS). The primary purpose of this pilot study was to evaluate the feasibility of a 5-week group kickboxing program and to measure changes in balance, mobility, and quality of life in individuals with MS associated with this training. This single-group repeated-measures study involved a convenience sample of 15 individuals with MS who had minimal to moderate levels of disability and were recruited from the community. Eleven participants completed all phases of testing and training. The intervention was a 5-week group kickboxing program performed 3 times per week. Outcome measures were assessed 5 weeks prior to the intervention, 1 week prior to the intervention, and within 1 week of completing the intervention. Outcome measures include gait speed, Timed Up & Go test, Berg Balance Scale, Dynamic Gait Index, Mini-BESTest, Activities Specific Balance Confidence scale, and the Multiple Sclerosis Quality of Life Survey. There were significant improvements in gait speed, some clinical measures of balance, and balance confidence following the intervention but no changes were observed in health-related quality of life. There were no unanticipated adverse events and compliance was high. Group kickboxing appears to be a feasible exercise activity for individuals with MS that may lead to improvement in select measures of balance and mobility. However, the clinical relevance of these findings is yet to be determined. Further investigation of this novel intervention may be warranted.

    European Database Multiple Sclerosis (EDMUS) is a standardized tool which allows the collection of clinical, biological, radiological and therapeutic data on multiple sclerosis (MS). A descriptive analysis of 199 patients was done using EDMUS (version 2.2). Most data agreed with previous published results, except a low 0.4 sex ratio. At the beginning of MS, 42 p. 100 of MS patients developed pyramidal and sensory involvements and 14 p. 100 retrobulbar optic neuritis. Optic neuritis was the most frequent initial symptom of relapsing-remitting MS (25.9 p. 100) but not in the chronic progressive form (5.5 p, 100; p < 0.01). Surprisingly, relapsing-remitting form occurred more frequently whereas the secondary progressive form was diagnosed less. The concordances between the three disability scales, EGS (EDMUS Grading Scale), EDSS (Expanded Disability Status Score) and AI (Hauser Ambulation Index) were correct. In clinical practice, EDMUS is user-friendly and rapid. The lack of radiological data and the necessary quantification of only one disability scale, EGS may be too restrictive. The analysis of most of clinical data is possible by using integrated selection within the software, but sometimes needs more complex procedures.

    In this study, an interval-parameter semi-infinite fuzzy-chance-constrained mixed-integer linear programming (ISIFCIP) approach is developed for supporting long-term planning of waste-management systems under multiple uncertainties in the City of Regina, Canada. The method improves upon the existing interval-parameter semi-infinite programming (ISIP) and fuzzy-chance-constrained programming (FCCP) by incorporating uncertainties expressed as dual uncertainties of functional intervals and multiple uncertainties of distributions with fuzzy-interval admissible probability of violating constraint within a general optimization framework. The binary-variable solutions represent the decisions of waste-management-facility expansion, and the continuous ones are related to decisions of waste-flow allocation. The interval solutions can help decision-makers to obtain multiple decision alternatives, as well as provide bases for further analyses of tradeoffs between waste-management cost and system-failure risk. In the application to the City of Regina, Canada, two scenarios are considered. In Scenario 1, the City's waste-management practices would be based on the existing policy over the next 25 years. The total diversion rate for the residential waste would be approximately 14%. Scenario 2 is associated with a policy for waste minimization and diversion, where 35% diversion of residential waste should be achieved within 15 years, and 50% diversion over 25 years. In this scenario, not only landfill would be expanded, but also CF and MRF would be expanded. Through the scenario analyses, useful decision support for the City's solid-waste managers and decision-makers has been generated. Three special characteristics of the proposed method make it unique compared with other optimization techniques that deal with uncertainties. Firstly, it is useful for tackling multiple uncertainties expressed as intervals, functional intervals, probability distributions, fuzzy sets, and their

    Thyroid hormone (TH) is required for limb development in Xenopus laevis. Specific cell types in the growing limb were targeted for expression of a dominant negative form of the TH receptor by sperm-mediated transgenesis. Limb muscle development, the innervation of muscle from the spinal cord, and cartilage growth can be inhibited without affecting patterning of the limb or differentiation of other cell types. Remodeling of the skin occurs late in metamorphosis after the limb has formed. The coordination of these independent programs is affected in part by the control that TH exerts over DNA replication in all cell types of the limb.

    The III-V semiconductor materials system that was selected for continued cascade cell development was the AlGaAs cell on GaAs cell structure. The tunnel junction used as transparent ohmic contact between the top cell and the bottom cell continued to be the central difficulty in achieving the program objective of 25 percent AMO efficiency at 25 C. During the tunnel junction and top cell developments it became apparent that the AlGaAs cell has potential for independent development as a single junction converter and is a logical extension of the present GaAs heteroface technology.

    Background Dietary factors have been discussed to influence risk or disease course of multiple sclerosis (MS). Specific diets are widely used among patients with MS. Objective To design and pilot-test an evidence based patient education program on dietary factors in MS. Methods We performed a systematic literature search on the effectiveness of dietary interventions in MS. A web-based survey among 337 patients with MS and 136 healthy controls assessed knowledge, dietary habits and information needs. An interactive group education program was developed and pilot-tested. Results Fifteen randomised-controlled trials (RCTs) were included in the systematic review. Quality of evidence was low and no clear benefit could be seen. Patients with MS significantly more often adhered to a `Mediterranean Diet`(29.7% versus 14.0%, p<0.001) compared to controls. 143 (42%) of the patients with MS had tried special MS diets. Important information needs addressed effectiveness of MS diets (44%) and relation between nutrition and MS (43%). A pilot test of our newly developed patient education program with 13 participants showed excellent comprehensibility and the MS-specific content was judged as very important. However, the poor evidence base for dietary approaches in MS was perceived disappointing. Conclusions Development and pilot-testing of an evidence-based patient education program on nutrition and MS is feasible. Patient satisfaction with the program suffers from the lack of evidence. Further research should focus on generating evidence for the potential influence of lifestyle habits (diet, physical activity) on MS disease course thus meeting the needs of patients with MS.

This tool allows the identification of divergent sequences in MSAs by scoring the contribution of each row in the alignment to its quality using a sum-of-pair-based method and additional analyses. Our main goal is to provide users with objective data in order to take informed decisions about the relevance and/or pertinence of including/retaining a particular sequence in an MSA. EvalMSA is written in standard Perl and also uses some routines from the statistical language R. Therefore, it is necessary to install the R-base package in order to get full functionality.

    An interactive Fortran program, MUCRA, is presented. The program can perform randomization analysis of a completely randomized or randomized-blocks design extended to growth and response curves. A single-step Scheffé-type procedure as well as the Peritz's closed step-down procedure have been implemented which control the familywise type I error-rate. In general, MUCRA is suitable as a computer tool for a distribution-free analysis of variance with repeated measures. The use of MUCRA is demonstrated by analyzing the effects oxprenolol and atenolol have on exercise heart rate. Oxprenolol is a non-selective beta-blocker with moderate intrinsic sympathomimetic activity (ISA), given by the Oros delivery system. Atenolol is a beta 1-selective blocker without ISA. A randomized placebo-controlled crossover design was used to compare the effects of the beta 1-blockers on heart rate during a progressive maximal exercise test on a bicycle ergometer. Application of the Scheffé-type procedure showed that the two drugs significantly (alpha = .05) reduce the heart rate during the exercise test at the three prechosen times (2, 5, and 24 hr) after intake. The reduction from atenolol is more pronounced than from oxprenolol Oros at 2 and 5 hr.

    Background Despite increased attention to dentists’ role in curbing opioid misuse, abuse, and diversion, information regarding prescribing practices and the frequency of multiple concurrent opioid prescriptions among dental patients is limited. Methods Prescription drug monitoring program (PDMP) data for South Carolina representing dispensed medication for patients prescribed at least one opioid by a dentist over the most recently available two-year frame (2012–2013) was reviewed. Descriptive analyses examined: (1) types, frequency of dental opioid prescriptions; and, (2) frequency of existing multiple concurrent opioid prescriptions among dental patients. Results Nearly all dispensed dental opioid prescriptions (99.9%; n = 653,650) were for immediate release opioids and were initial fills (96.2%). Hydrocodone (76.1%) and oxycodone (12.2%) combination products were the most frequently dispensed opioids prescribed by dentists. Individuals under 21 years of age received 11.2% of dentist prescribed opioids dispensed. Patients with multiple concurrent opioid prescriptions were identified within 30-day (n=113,818), 90-day (n=166,124), and 180-day (n=205,576) timeframes. Conclusions Dentists prescribed a high volume of immediate release opioids dispensed in South Carolina. A notable minority of dental patients had incident(s) of multiple pre-existing opioid prescriptions, a factor implicated in patient misuse, abuse, overdose, and diversion Practical Implications Use of a PDMP prior to prescribing provides a record of controlled substances dispensed to a patient, and may inform prescribing, coordination of care, and addiction screening or referral. Patients should be provided information regarding misuse behaviors and their risks, as well as the importance of secure storage and disposal of leftover opioid medications. PMID:27055600

    2007-01-01

    Essential thrombocythemia (ET) is an acquired myeloproliferative disorder (MPD) characterized by a sustained elevation of platelet number with a tendency for thrombosis and hemorrhage. The prevalence in the general population is approximately 30/100,000. The median age at diagnosis is 65 to 70 years, but the disease may occur at any age. The female to male ratio is about 2:1. The clinical picture is dominated by a predisposition to vascular occlusive events (involving the cerebrovascular, coronary and peripheral circulation) and hemorrhages. Some patients with ET are asymptomatic, others may experience vasomotor (headaches, visual disturbances, lightheadedness, atypical chest pain, distal paresthesias, erythromelalgia), thrombotic, or hemorrhagic disturbances. Arterial and venous thromboses, as well as platelet-mediated transient occlusions of the microcirculation and bleeding, represent the main risks for ET patients. Thromboses of large arteries represent a major cause of mortality associated with ET or can induce severe neurological, cardiac or peripheral artery manifestations. Acute leukemia or myelodysplasia represent only rare and frequently later-onset events. The molecular pathogenesis of ET, which leads to the overproduction of mature blood cells, is similar to that found in other clonal MPDs such as chronic myeloid leukemia, polycythemia vera and myelofibrosis with myeloid metaplasia of the spleen. Polycythemia vera, myelofibrosis with myeloid metaplasia of the spleen and ET are generally associated under the common denomination of Philadelphia (Ph)-negative MPDs. Despite the recent identification of the JAK2 V617F mutation in a subset of patients with Ph-negative MPDs, the detailed pathogenetic mechanism is still a matter of discussion. Therapeutic interventions in ET are limited to decisions concerning the introduction of anti-aggregation therapy and/or starting platelet cytoreduction.

    In every country, health and prevention "come down" from the authorities responsible for this mission by way of planners, local authorities, and peer educators until it reaches the target population. International and national systems function on the premise of a top-down transmission, with little room for integrating local information that might provide a better understanding of the implementation process. This analysis is based on an empirical evaluative research of HIV/AIDS prevention projects with sex workers in a remote area of northern Brazil. It illustrates how nursing sociopolitical analysis can reveal how political interests can have perverse effects by contaminating the group's internal relations and with established partnerships, thereby weakening the impact of prevention programs. These effects can seriously affect community relations and social practices, far beyond the technical division of work and political hierarchies in the sociosanitary network.

    The thermal vacuum test optimization model developed to provide an approach to the optimization of a test program based on prediction of flight performance with a single flight option in mind is extended to consider reflight as in space shuttle missions. The concept of 'utility', developed under the name of 'availability', is used to follow performance through the various options encountered when the capabilities of reflight and retrievability of space shuttle are available. Also, a 'lost value' model is modified to produce a measure of the probability of a mission's success, achieving a desired utility using a minimal cost test strategy. The resulting matrix of probabilities and their associated costs provides a means for project management to evaluate various test and reflight strategies.

    A process to collect universal, mandatory autotransfusion (ATS) procedure quality indicators to measure and monitor ATS quality improvement was designed and implemented by Fresenius Medical Care Extracorporeal Alliance (FMCEA) an outsource provider of extracorporeal services. The indicator program collected and evaluated data that reflect real-world extracorporeal clinical practices and outcomes. The indicator reports provide our clinicians, client physicians, and partner institutions with confidential reports that allow comparison of their practice to evidenced-based performance standards. All ATS procedures reviewed were performed on non-open-heart surgery procedures (on pump or off pump), including vascular, thoracic, orthopedic, and general surgery. After continuous collection and analysis of the indicator data, a hospital is given a report with three components: 1) data analysis that reports summary results and benchmarks the hospital against the other reporting hospitals, 2) corrective action plan that allows the clinical manager to document their investigations and outline plans for continuous quality improvement; and 3) raw data tabulation that allows the clinical manager to identify individual cases that are outliers from the target goal to facilitate local chart reviews. This communication describes FMCEA's ATS Quality Indicator Program and presents the collective results for the first 13 months (January 2002--January 2003) of data collection. Physicians and ATS service client hospitals value the Quality Indicator Process Reports. ATS service managers use the reports and the subsequent process improvement to meet AaBB (American Association of Blood Banks) and JCAHO (Joint Commission on Accreditation of Healthcare Organizations) standards and guidelines for providing safe patient-care services.

  3. Report for simultaneous, multiple independently steered beam study for Airborne Electronically Steerable Phased Array (AESPA) program

    1978-01-01

    Design concepts of an array for the formation of multiple, simultaneous, independently pointed beams for satellite communication links were investigated through tradeoffs of various approaches which were conceived as possible solutions to the problem. After the preferred approach was selected, a more detailed design was configured and is presented as a candidate system that should be given further consideration for development leading to a preliminary design. This array uses an attenuator and a phase shifter with every element. The aperture excitation necessary to form the four beams is calculated and then placed across the array using these devices. Pattern analysis was performed for two beam and four beam cases with numerous patterns being presented. Parameter evaluation shown includes pointing accuracy and beam shape, sidelobe characteristics, gain control, and beam normalization. It was demonstrated that a 4 bit phase shifter and a 6 bit, 30 dB attenuator were sufficient to achieve adequate pattern performances. The phase amplitude steered multibeam array offers the flexibility of 1 to 4 beams with an increase in gain of 6 dB if only one beam is selected.

    A furnace with two hot zones holds multiple analysis tubes. Each tube has a separable sample-packing section positioned in the first hot zone and a catalyst-packing section positioned in the second hot zone. A mass flow controller is connected to an inlet of each sample tube, and gas is supplied to the mass flow controller. Oxygen is supplied through a mass flow controller to each tube to either or both of an inlet of the first tube and an intermediate portion between the tube sections to intermingle with and oxidize the entrained gases evolved from the sample. Oxidation of those gases is completed in the catalyst in each second tube section. A thermocouple within a sample reduces furnace temperature when an exothermic condition is sensed within the sample. Oxidized gases flow from outlets of the tubes to individual gas cells. The cells are sequentially aligned with an infrared detector, which senses the composition and quantities of the gas components. Each elongated cell is tapered inward toward the center from cell windows at the ends. Volume is reduced from a conventional cell, while permitting maximum interaction of gas with the light beam. Reduced volume and angulation of the cell inlets provide rapid purgings of the cell, providing shorter cycles between detections. For coal and other high molecular weight samples, from 50% to 100% oxygen is introduced to the tubes.

    Background Gas chromatography-mass spectrometry (GC-MS) is a robust platform for the profiling of certain classes of small molecules in biological samples. When multiple samples are profiled, including replicates of the same sample and/or different sample states, one needs to account for retention time drifts between experiments. This can be achieved either by the alignment of chromatographic profiles prior to peak detection, or by matching signal peaks after they have been extracted from chromatogram data matrices. Automated retention time correction is particularly important in non-targeted profiling studies. Results A new approach for matching signal peaks based on dynamic programming is presented. The proposed approach relies on both peak retention times and mass spectra. The alignment of more than two peak lists involves three steps: (1) all possible pairs of peak lists are aligned, and similarity of each pair of peak lists is estimated; (2) the guide tree is built based on the similarity between the peak lists; (3) peak lists are progressively aligned starting with the two most similar peak lists, following the guide tree until all peak lists are exhausted. When two or more experiments are performed on different sample states and each consisting of multiple replicates, peak lists within each set of replicate experiments are aligned first (within-state alignment), and subsequently the resulting alignments are aligned themselves (between-state alignment). When more than two sets of replicate experiments are present, the between-state alignment also employs the guide tree. We demonstrate the usefulness of this approach on GC-MS metabolic profiling experiments acquired on wild-type and mutant Leishmania mexicana parasites. Conclusion We propose a progressive method to match signal peaks across multiple GC-MS experiments based on dynamic programming. A sensitive peak similarity function is proposed to balance peak retention time and peak mass spectra similarities

    Background Indoor Residual Spraying (IRS), insecticide-treated nets (ITNs) and long-lasting insecticidal nets (LLINs) are key components in malaria prevention and control strategy. However, the development of resistance by mosquitoes to insecticides recommended for IRS and/or ITNs/LLINs would affect insecticide-based malaria vector control. We assessed the susceptibility levels of Anopheles arabiensis to insecticides used in malaria control, characterized basic mechanisms underlying resistance, and evaluated the role of public health use of insecticides in resistance selection. Methodology/Principal findings Susceptibility status of An. arabiensis was assessed using WHO bioassay tests to DDT, permethrin, deltamethrin, malathion and propoxur in Ethiopia from August to September 2009. Mosquito specimens were screened for knockdown resistance (kdr) and insensitive acetylcholinesterase (ace-1R) mutations using AS-PCR and PCR-RFLP, respectively. DDT residues level in soil from human dwellings and the surrounding environment were determined by Gas Chromatography with Electron Capture Detector. An. arabiensis was resistant to DDT, permethrin, deltamethrin and malathion, but susceptible to propoxur. The West African kdr allele was found in 280 specimens out of 284 with a frequency ranged from 95% to 100%. Ace-1R mutation was not detected in all specimens scored for the allele. Moreover, DDT residues were found in soil samples from human dwellings but not in the surrounding environment. Conclusion The observed multiple-resistance coupled with the occurrence of high kdr frequency in populations of An. arabiensis could profoundly affect the malaria vector control programme in Ethiopia. This needs an urgent call for implementing rational resistance management strategies and integrated vector control intervention. PMID:21264325

    In centralized decision problems, it is not complicated for decision-makers to make modelling technique selections under uncertainty. When a decentralized decision problem is considered, however, choosing appropriate models is no longer easy due to the difficulty in estimating the other decision-makers' inconclusive decision criteria. These decision criteria may vary with different decision-makers because of their special risk tolerances and management requirements. Considering the general differences among the decision-makers in decentralized systems, we propose a general framework of fuzzy bilevel programming including hybrid models (integrated with different modelling methods in different levels). Specially, we discuss two of these models which may have wide applications in many fields. Furthermore, we apply the proposed two models to formulate a pricing decision problem in a decentralized supply chain with fuzzy coefficients. In order to solve these models, a hybrid intelligent algorithm integrating fuzzy simulation, neural network and particle swarm optimization based on penalty function approach is designed. Some suggestions on the applications of these models are also presented.

  8. Multiple spatially distributed stimulators and timing programs for entrainment of activation during ventricular fibrillation.

    Activation sequences during ventricular fibrillation (VF) display complex pattern and fast rate. Recent evidence suggests that even during VF an excitable gap may exist. Existence of excitable gap lead us to hypothesize that it should be possible to entrain activation patterns during VF by using spatially distributed and temporally phased pacing strength stimuli. We describe here the electronics hardware and software that were developed to test our hypothesis. Eight biphasic stimulators were designed and fabricated, each addressable via a TTL input and thus independently triggered. To minimize electrical interference from stimulus pulses the stimulators were optically isolated. A program written in C was used to deliver TTL inputs to time the sequence of stimulation. The parameters that could be varied were, pulse intensity, polarity, and duration, inter pulse interval and activation pattern cycle length. Restitution's of action potential duration, conduction velocity, and complex activation patterns make the timing of stimulators complex. To aid in optimal timing of these stimulators, we used a Luo-Rudy ionic model of cellular activation to simulate VF in a matrix of 400 x 400 cells. Entrainment of activation was verified using animated displays of activation sequences. Using results of simulation we verified the function of our stimulators experimentally using electrically induced VF in canines and by using electrograms recorded from 121-electrode patch. Our results show that the developed hardware and software can be used to deliver distributed stimuli in a flexible and effective pattern, which may aid in development of approaches for treatment of VF.

    MuSim is a new user-friendly program designed to interface to many different particle simulation codes, regardless of their data formats or geometry descriptions. It presents the user with a compelling graphical user interface that includes a flexible 3-D view of the simulated world plus powerful editing and drag-and-drop capabilities. All aspects of the design can be parametrized so that parameter scans and optimizations are easy. It is simple to create plots and display events in the 3-D viewer (with a slider to vary the transparency of solids), allowing for an effortless comparison of different simulation codes. Simulation codes: G4beamline, MAD-X, and MCNP; more coming. Many accelerator design tools and beam optics codes were written long ago, with primitive user interfaces by today's standards. MuSim is specifically designed to make it easy to interface to such codes, providing a common user experience for all, and permitting the construction and exploration of models with very little overhead. For today's technology-driven students, graphical interfaces meet their expectations far better than text-based tools, and education in accelerator physics is one of our primary goals.

  10. Multiple Cis-acting elements modulate programmed -1 ribosomal frameshifting in Pea enation mosaic virus.

    2016-01-29

    Programmed -1 ribosomal frameshifting (-1 PRF) is used by many positive-strand RNA viruses for translation of required products. Despite extensive studies, it remains unresolved how cis-elements just downstream of the recoding site promote a precise level of frameshifting. The Umbravirus Pea enation mosaic virus RNA2 expresses its RNA polymerase by -1 PRF of the 5'-proximal ORF (p33). Three hairpins located in the vicinity of the recoding site are phylogenetically conserved among Umbraviruses. The central Recoding Stimulatory Element (RSE), located downstream of the p33 termination codon, is a large hairpin with two asymmetric internal loops. Mutational analyses revealed that sequences throughout the RSE and the RSE lower stem (LS) structure are important for frameshifting. SHAPE probing of mutants indicated the presence of higher order structure, and sequences in the LS may also adapt an alternative conformation. Long-distance pairing between the RSE and a 3' terminal hairpin was less critical when the LS structure was stabilized. A basal level of frameshifting occurring in the absence of the RSE increases to 72% of wild-type when a hairpin upstream of the slippery site is also deleted. These results suggest that suppression of frameshifting may be needed in the absence of an active RSE conformation. © The Author(s) 2015.

    Naturally occurring fluorides of varying levels made possible a study do determine if continuous, lifetime use of home drinking water fluoridated to optimum levels combined with the use of school fluoridated water beginning at school age causes objectionable levels of dental fluorosis as defined by Dr. H. Trendley Dean in 1936. Examinations were performed on 120 children who had fluoride concentrations in home well water ranging from 0.1 to 6.5 ppm and attended a school with a private water source containing 4.5 ppm natural fluoride (5.6 times the optimum for community fluoridation in the area). Fluorosis scores were calculated for each of four groups formed according to fluoride concentrations in home water supplies. The group with an average concentration of 0.87 ppm was found to have a Community Index of Dental Fluorosis well within Dean's normal limits. The results suggest that children consuming water at home containing the optimal fluoride concentration and drinking water at school containing the recommended fluoride level (4.5 times the optimum) are not at risk to dental fluorosis that impairs appearance. If this finding is corroborated by future clinical studies, the target population for school fluoridation can be expanded and the administration of these programs facilitated. PMID:7302108

    Classical neural networks are composed of neurons whose nature is determined by a certain function (the neuron model), usually pre-specified. In this paper, a type of neural network (NN-GP) is presented in which: (i) each neuron may have its own neuron model in the form of a general function, (ii) any layout (i.e network interconnection) is possible, and (iii) no bias nodes or weights are associated to the connections, neurons or layers. The general functions associated to a neuron are learned by searching a function space. They are not provided a priori, but are rather built as part of an Evolutionary Computation process based on Genetic Programming. The resulting network solutions are evaluated based on a fitness measure, which may, for example, be based on classification or regression errors. Two real-world examples are presented to illustrate the promising behaviour on classification problems via construction of a low-dimensional representation of a high-dimensional parameter space associated to the set of all network solutions.

    Salt-bridge and network salt-bridge are specific electrostatic interactions that contribute to the overall stability of proteins. In hierarchical protein folding model, these interactions play crucial role in nucleation process. The advent and growth of protein structure database and its availability in public domain made an urgent need for context dependent rapid analysis of salt-bridges. While these analyses on single protein is cumbersome and time-consuming, batch analyses need efficient software for rapid topological scan of a large number of protein for extracting details on (i) fraction of salt-bridge residues (acidic and basic). (ii) Chain specific intra-molecular salt-bridges, (iii) inter-molecular salt-bridges (protein-protein interactions) in all possible binary combinations (iv) network salt-bridges and (v) secondary structure distribution of salt-bridge residues. To the best of our knowledge, such efficient software is not available in public domain. At this juncture, we have developed a program i.e. SBION which can perform all the above mentioned computations for any number of protein with any number of chain at any given distance of ion-pair. It is highly efficient, fast, error-free and user friendly. Finally we would say that our SBION indeed possesses potential for applications in the field of structural and comparative bioinformatics studies. SBION is freely available for non-commercial/academic institutions on formal request to the corresponding author (akbanerjee@biotech.buruniv.ac.in).

    There is increasing evidence that physical exercise leads to numerous positive effects in PwMS. However, long-term effects of exercise may only be achievable if training is implemented in daily routine. Enabling patients to exercise regularly, we developed a patient education program focused on evidence-based information of training. PwMS were educated in neurophysiological effects of physical exercise, exercise-induced benefits for PwMS, and risk factors (e.g., weather). Fifteen PwMS were analyzed before (T0) and after (T1) a 12-week patient education. Afterwards, participants performed their exercises autonomously for 32 weeks and were tested in sustainability tests (T2). Guided interviews were carried out, additionally. Significant improvements from T0 to T1 were found in 6MWT, gait velocity, TUG, fatigue, and quality of life. Significant results of TUG and gait velocity from T1 to T2 demonstrated that participants kept few effects after the 32-week training phase. Qualitative analyses showed improved self-confidence and identified training strategies and barriers. This pilot study provides evidence that PwMS are able to acquire good knowledge about physical exercise and apply this knowledge successfully in training management. One might conclude that this exercise-based patient education seems to be a feasible option to maintain or improve patients' integral constitution concerning physical and mental health.

    Essential genes are defined as required for the survival of an organism or a cell. They are of particular interests, not only for their essential biological functions, but also in practical applications, such as identifying effective drug targets to pathogenic bacteria and fungi. The budding yeast Saccharomyces cerevisiae has approximately 6,000 open reading frames, 15 to 20% of which are deemed as essential. Some of the essential genes, however, appear to perform non-essential functions, such as aging and cell death, while many of the non-essential genes play critical roles in cell survival. In this paper, we reviewed and analyzed the levels of essentiality of the Saccharomyces cerevisiae genes and have grouped the genes into four categories: (1) Conditional essential: essential only under certain circumstances or growth conditions; (2) Essential: required for survival under optimal growth conditions; (3) Redundant essential: synthetic lethal due to redundant pathways or gene duplication; and (4) Absolute essential: the minimal genes required for maintaining a cellular life under a stress-free environment. The essential and non-essential functions of the essential genes were further analyzed. PMID:28357303

    Multi-view imaging is the primary modality for high-spatial-resolution imaging of the vasculature. The 3D vascular structure can be reconstructed if the imaging geometries are determined using known corresponding point-pairs (or k-tuples) in two or more images. Because the accuracy improves with more input corresponding point-pairs, we propose a new technique to automatically determine corresponding point-pairs in multi-view (k-view) images, from 2D vessel image centerlines. We formulate the problem, first as a multi-partite graph-matching problem. Each 2D centerline point is a vertex; each individual graph contains all vessel-points (vertices) in an image. The weight ('cost') of the edges between vertices (in different graphs) is the shortest distance between the points' respective projection-lines. Using this construction, a universe of mappings (k-tuples) is created, each k-tuple having k vertices (one from each image). A k-tuple's weight is the sum of pair-wise 'costs' of its members. Ideally, a set of such mappings is desired that preserves the ordering of points along the vessel and minimizes an appropriate global cost function, such that all vertices (in all graphs) participate in at least one mapping. We formulate this problem as a special case of the well-studied Set-Cover problem with additional constraints. Then, the equivalent linear program is solved, and randomized-rounding techniques are used to yield a feasible set of mappings. Our algorithm is efficient and yields a theoretical quality guarantee. In simulations, the correct matching is achieved in ~98% cases, even with high input error. In clinical data, apparently correct matching is achieved in >90% cases. This method should provide the basis for improving the calculated 3D vasculature from multi-view data-sets.

    We describe "NewVision", a program designed for rapid interactive display, sectioning, and comparison of multiple large three-dimensional (3-D) reconstructions. User tools for navigating within large 3-D data sets and selecting local subvolumes for display, combined with view caching, fast integer interpolation, and background tasking, provide highly interactive viewing of arbitrarily sized data sets on Silicon Graphics systems ranging from simple workstations to supercomputers. Multiple windows, each showing different views of the same 3-D data set, are coordinated through mapping of local coordinate systems to a single global world coordinate system. Mapping to a world coordinate system allows quantitative measurements from any open window as well as creation of linked windows in which operations such as panning, zooming, and 3-D rotations of the viewing perspective in any one window are mirrored by corresponding transformations in the views shown in other linked windows. The specific example of tracing 3-D fiber trajectories is used to demonstrate the potential of the linked window concept. A global overview of NewVision's design and organization is provided, and future development directions are briefly discussed.

    This study assessed the use of microswitch-aided programs to help three non-ambulatory adults with multiple disabilities exercise foot-leg responses. Those responses served to activate a largely neglected part of the participants' body, with possibly positive physical implications (e.g., for blood circulation, swelling, and muscle strength). Intervention focused on the left and right foot-leg response, separately. Eventually, sessions with one response were alternated with sessions with the other response. Responses were monitored via microswitches and followed by 8s of preferred stimulation (e.g., music and vibrotactile stimulation), which was automatically delivered. The results showed that all three participants had high levels of foot-leg responses during the intervention phases and a 3-week post-intervention check. The participants also displayed expressions of positive involvement during those study periods (i.e., engaged in behaviors, such as music-related head movements, smiles, or touching the vibratory devices) that could be interpreted as forms of interest/pleasure and happiness. These results are in line with previous findings in this area and can be taken as an important confirmation of the strength and dependability of the approach in motivating non-ambulatory persons with multiple disabilities to engage in foot-leg movements. The practical implications of these findings are discussed.

    SAGE (Serial Analysis of Gene Expression) experiments generate short nucleotide sequences called ‘tags’ which are assumed to map unambiguously to their original transcripts (1 tag to 1 transcript mapping). Nevertheless, many tags are generated that do not map to any transcript or map to multiple transcripts. Current bioinformatics resources, such as SAGEmap and TAGmapper, have focused on reducing the number of unmapped tags. Here, we describe SAGETTARIUS, a new high-throughput program that performs successive precise Nla3 and Sau3A tag to transcript mapping, based on specifically designed Virtual Tag (VT) libraries. First, SAGETTARIUS decreases the number of tags mapped to multiple transcripts. Among the various mapping resources compared, SAGETTARIUS performed the best in this respect by decreasing up to 11% the number of multiply mapped tags. Second, SAGETTARIUS allows the establishment of a guideline for SAGE experiment sequencing efforts through efficient mapping of the CRT (Cytoplasmic Ribosomal protein Transcripts)-specific tags. Using all publicly available human and mouse Nla3 SAGE experiments, we show that sequencing 100 000 tags is sufficient to map almost all CRT-specific tags and that four sequencing stages can be identified when carrying out a human or mouse SAGE project. SAGETTARIUS is web interfaced and freely accessible to academic users. PMID:17884916

SAGETTARIUS is web interfaced and freely accessible to academic users.

    Numerous strategies have been suggested to increase recruitment of family physicians to rural communities and smaller regional centers. One approach has been to implement distributed postgraduate education programs where trainees spend substantial time in such communities. The purpose of the current study was to compare the eventual practice location of family physicians who undertook their postgraduate training through a single university but who were based in either metropolitan or distributed, non-metropolitan communities. Since 1998, the Department of Family Practice at the University of British Columbia in Canada has conducted an annual survey of its residents at 2, 5, and 10 years after completion of training. The authors received Ethics Board approval to use this anonymized data to identify personal and educational factors that predict future practice location. The overall response rate was 45%. At 2 years (N=222), residents trained in distributed sites were 15 times more likely to enter practice in rural communities, small towns and regional centers than those who trained in metropolitan teaching centers. This was even more predictive for retention in non-urban practice sites. Among the subgroup of physicians who remained in a single practice location for more than a year preceding the survey, those who trained in smaller sites were 36 times more likely to choose a rural or regional practice setting. While the vast majority of those trained in metropolitan sites chose an urban practice location, a subgroup of those with some rural upbringing were more likely to practice in rural or regional settings. Trainees from distributed sites considered themselves more prepared for practice regardless of ultimate practice location. Participation in a distributed postgraduate family medicine training site is an important predictor of a non-urban practice location. This effect persists for 10 years after completion of training and is independent of other predictors of

    The first of these two studies extended preliminary evidence on the use of technology-based programs for enabling students with severe and profound multiple disabilities to choose and access environmental stimuli on their own. Each of the three participants had two microswitches linked to specific sets of stimuli through a computer system. The activation of one of the microswitches triggered the computer system to present a sample of one of the stimuli. If the student chose it, the computer system turned it on for a specific time interval. The second study tested a new technology that allowed the students to choose and access the chosen stimuli with the involvement of the caregiver. The two participants had three microswitches linked to a computer system. The participants' choice of a stimulus alerted the caregiver who then got involved in the stimulation process. The results of both studies showed that the participants learned to activate the basic microswitches consistently, had high percentages of choice for the stimulus samples presented by the computer but with wide differences across stimuli, and largely maintained this performance at a 2-month post-intervention check. These findings were analyzed in terms of the usability of the two types of programs, the role they may play within educational and living contexts, and their innovative technical dimensions.

    Balance and postural control (PC) disorders are frequent motor disorder symptoms associated with multiple sclerosis (MS). To demonstrate the potential improvements in balance and PC among patients with MS who complete a virtual reality telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. 50 patients was recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received telerehabilitation treatment using the Xbox 360® console monitored via videoconference. Experimental group attended 40 sessions, four sessions per week (20 min per session). The treatment schedule lasted 10 weeks for both groups. A computerised dynamic posturography and clinical outcomes (Berg Balance and Tinettti scales) were used at baseline and at the end of the treatment. Results showed an improvement over general balance in both groups. Visual preference, the contribution of vestibular information, mean response time and Tinetti test yielded significant differences in the experimental group. An ANOVA revealed significant between-group post-treatment differences in the composite equilibrium score, Berg and Tinetti scales in the experimental group. We suggest that our virtual reality program enables anticipatory PC and response mechanisms and might serve as a successful therapeutic alternative in situations in which conventional therapy is not readily available.

    from a fixed setting (2.5 V at 0.50 ms) to Copt, the battery current decreased by 17.5% (P < 0.0001). In conclusion, pacing thresholds in patients with chronic ventricular leads are stable enough to permit programming battery-saving low output settings, if pacemakers are followed on a regular basis. Titration of a 2:1 safety charge (a 3:1 safety charge in pacemaker dependent patients) by prolongation of pulse duration is safe, provided that pulse amplitude is chosen carefully. Using this approach, current consumption can significantly be reduced without jeopardizing patient's life.

    Objectives This paper reports on results from a randomized experimental trial of the effects of the Family Bereavement Program (FBP) on multiple measures of grief experienced by parentally-bereaved children and adolescents over a six year period of time. Method Participants were 244 youth (ages 8–16, mean age = 11.4 years) from 156 families that had experienced the death of a parent. The sample consisted of 53% boys; ethnicity was 67% non-Hispanic white and 33% ethnic minority. Families were randomly assigned to the FBP (N=135) or a literature control condition (N=109). Two grief measures, the Texas Revised Inventory of Grief (TRIG) and the Intrusive Grief Thoughts Scale (IGTS) were administered at four times over six years, pre-test, post-test, eleven-month and six-year follow-ups. A third measure, an adaptation of the Inventory of Traumatic Grief (ITG) was administered only at the six-year follow-up. Results The FBP showed a greater reduction as compared to controls in their level of problematic grief (IGTS) at post-test and six-year follow-up and in the percent at clinical levels of problematic grief at the post-test. The FBP also reduced scores on a dimension of the ITG, Social Detachment/Insecurity, at six-year follow-up for three subgroups; those who experienced lower levels of grief at program entry, older youth, and boys. Conclusion These are the first findings from a randomized trial with long-term follow-up of the effects of a program to reduce problematic levels of grief of parentally-bereaved youth. PMID:20350025

    Saccharomyces cerevisiae Kre6 is a type II membrane protein essential for cell wall β-1,6-glucan synthesis. Recently we reported that the majority of Kre6 is in the endoplasmic reticulum (ER), but a significant portion of Kre6 is found in the plasma membrane of buds, and this polarized appearance of Kre6 is required for β-1,6-glucan synthesis. An essential membrane protein, Keg1, and ER chaperon Rot1 bind to Kre6. In this study we found that in mutant keg1-1 cells, accumulation of Kre6 at the buds is diminished, binding of Kre6 to Keg1 is decreased, and Kre6 becomes susceptible to ER-associated degradation (ERAD), which suggests Keg1 participates in folding and transport of Kre6. All mutants of the calnexin cycle member homologues (cwh41, rot2, kre5, and cne1) showed defects in β-1,6-glucan synthesis, although the calnexin chaperon system is considered not functional in yeast. We found synthetic defects between them and keg1-1, and Cne1 co-immunoprecipitated with Keg1 and Kre6. A stronger binding of Cne1 to Kre6 was detected when two glucosidases (Cwh41 and Rot2) that remove glucose on N-glycan were functional. Skn1, a Kre6 homologue, was not detected by immunofluorescence in the wild type yeast, but in kre6Δ cells it became detectable and behaved like Kre6. In conclusion, the action of multiple ER chaperon-like proteins is required for proper folding and localization of Kre6 and probably Skn1 to function in β-1,6-glucan synthesis.

    Distributing a multiple computer-tailored smoking cessation intervention through the Internet has several advantages for both provider and receiver. Most important, a large audience of smokers can be reached while a highly individualized and personal form of feedback can be maintained. However, such a smoking cessation program has yet to be developed and implemented in The Netherlands. To investigate the effects of a Web-based multiple computer-tailored smoking cessation program on smoking cessation outcomes in a sample of Dutch adult smokers. Smokers were recruited from December 2009 to June 2010 by advertising our study in the mass media and on the Internet. Those interested and motivated to quit smoking within 6 months (N = 1123) were randomly assigned to either the experimental (n = 552) or control group (n = 571). Respondents in the experimental group received the fully automated Web-based smoking cessation program, while respondents in the control group received no intervention. After 6 weeks and after 6 months, we assessed the effect of the intervention on self-reported 24-hour point prevalence abstinence, 7-day point prevalence abstinence, and prolonged abstinence using logistic regression analyses. Of the 1123 respondents, 449 (40.0%) completed the 6-week follow-up questionnaire and 291 (25.9%) completed the 6-month follow-up questionnaire. We used a negative scenario to replace missing values. That is, we considered respondents lost to follow-up to still be smoking. The computer-tailored program appeared to have significantly increased 24-hour point prevalence abstinence (odds ratio [OR] 1.85, 95% confidence interval [CI] 1.30-2.65), 7-day point prevalence abstinence (OR 2.17, 95% CI 1.44-3.27), and prolonged abstinence (OR 1.99, 95% CI 1.28-3.09) rates reported after 6 weeks. After 6 months, however, no intervention effects could be identified. Results from complete-case analyses were similar. The results presented suggest that the Web-based computer

    Background MSmonitor is an interactive web-based program for self-management and integrated, multidisciplinary care in multiple sclerosis. Methods To assess the utilization and valuation by persons with multiple sclerosis, we held an online survey among those who had used the program for at least 1 year. We evaluated the utilization and meaningfulness of the program’s elements, perceived use of data by neurologists and nurses, and appreciation of care, self-management, and satisfaction. Results Fifty-five persons completed the questionnaire (estimated response rate 40%). The Multiple Sclerosis Impact Profile (MSIP), Medication and Adherence Inventory, Activities Diary, and electronic consultation (e-consult) were used by 40%, 55%, 47%, and 44% of respondents and were considered meaningful by 83%, 81%, 54%, and 88%, respectively. During out-patient consultations, nurses reportedly used the MSmonitor data three to six times more frequently than neurologists. As to nursing care, more symptoms were dealt with (according to 54% of respondents), symptoms were better discussed (69%), and the overall quality of care had improved (60%) since the use of the program. As to neurological care, these figures were 24%, 31%, and 27%, respectively. In 46% of the respondents, the insight into their symptoms and disabilities had increased since the use of the program; the MSIP, Activities Diary, and e-consult had contributed most to this improvement. The overall satisfaction with the program was 3.5 out of 5, and 73% of the respondents would recommend the program to other persons with multiple sclerosis. Conclusion A survey among persons with multiple sclerosis using the MSmonitor program showed that the MSIP, Medication and Adherence Inventory, Activities Diary, and e-consult were frequently used and that the MSIP, Medication and Adherence Inventory, and e-consult were appreciated the most. Moreover, the quality of nursing care, but not so neurological care, had improved, which

    The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) occlusion-derived virus (ODV) envelope protein ODV-E56 is essential for oral infection of larvae of Heliothis virescens. Bioassays with recombinant clones of AcMNPV lacking a functional odv-e56 gene showed that ODV-E56 was required for infectivity of both polyhedra and to a lesser extent, purified ODV. However, binding and fusion assays showed that ODV lacking ODV-E56 bound and fused to midgut cells at levels similar to ODV of wild-type virus. Fluorescence microscopy of midguts from larvae inoculated with ODV-E56-positive and -negative viruses that express GFP indicated that ODV-E56 was required for infection of the midgut epithelium. Purified ODV-E56 bound to several proteins in midgut-derived brush border membrane vesicles, but failed to rescue infectivity of ODV-E56-negative viruses in trans. These results indicate that ODV-E56 is a per os infectivity factor (pif-5) required for primary midgut infection at a point before or after virion binding and fusion.

    A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome (Sfbac). Transcriptional analysis revealed that sf32 is an early gene. Occlusion bodies (OBs) of Sf32null contained 62% more genomic DNA than viruses containing the sf32 gene, Sfbac and Sf32null-repair, although Sf32null DNA was three-fold less infective when injected in vivo. Sf32null OBs were 18% larger in diameter and contained 17% more nucleocapsids within ODVs than those of Sfbac. No significant differences were detected in OB pathogenicity (50% lethal concentration), speed-of-kill or budded virus production in vivo. In contrast, the production of OBs/larva was reduced by 39% in insects infected by Sf32null compared to those infected by Sfbac. The SF32 predicted protein sequence showed homology (25% identity, 44% similarity) to two adhesion proteins from Streptococcus pyogenes and a single N-mirystoylation site was predicted. We conclude that SF32 is a non-essential protein that could be involved in nucleocapsid organization during ODV assembly and occlusion, resulting in increased numbers of nucleocapsids within ODVs.

    Although resistance training adaptations in multiple sclerosis (MS) patients have been described, the detraining response in this population is largely unknown. [corrected] This study was designed to evaluate the effects of a 12-week detraining period on muscle strength (isometric and endurance) and muscle power of multiple sclerosis (MS) patients that had previously carried out a 12-week resistance training program (RTP). Forty-two MS patients were randomly assigned into two groups: an exercise group (EG) that performed a 12-week RTP for the knee extensors muscles; and a control group (CG), that did not perform any specific training. Knee extension maximal voluntary isometric contraction (MVIC), muscle power and muscle endurance were evaluated before and after the RTP, as well as 12 weeks after training completion. A strain gauge was used to measure the maximal voluntary isometric contraction and muscle power was assessed with a linear encoder. Muscle endurance was interpreted as the number of repetitions that a patient could perform in a single set of knee extension exercise. The EG increased MVIC and muscle power after the training period, although the training did not affect muscle endurance. After 12 weeks of detraining, MVIC returned to pre-training values but muscle power was still greater than pre-training values in the EG. The CG did not present any change in the variables measured during the intervention. A 12-week RTP improved MVIC and muscle power in MS patients. Additionally, 12 weeks of detraining blunted strength training adaptations in MS patients, although muscle power training adaptations were still evident after the detraining period.

    A program relying on microswitch clusters (i.e., combinations of microswitches) and preferred stimuli was recently developed to foster adaptive responses and head control in persons with multiple disabilities. In the last version of this program, preferred stimuli (a) are scheduled for adaptive responses occurring in combination with head control (i.e., head upright) and (b) last through the scheduled time only if head control is maintained for that time. The first of the present two studies was aimed at replicating this program with three new participants with multiple disabilities adding to the three reported by Lancioni et al. [Lancioni, G. E., Singh, N. N., O'Reilly, M. F., Sigafoos, J., Didden, R., Oliva, D., et al. (2007). Fostering adaptive responses and head control in students with multiple disabilities through a microswitch-based program: Follow-up assessment and program revision. Research in Developmental Disabilities, 28, 187-196]. The second of the two studies served to carry out an expert validation of the program's effects on head control and general physical condition with the three participants of Study I as well as the three participants involved in the Lancioni et al. study mentioned above. The expert raters were 72 new physiotherapists and 72 experienced physiotherapists. The results of Study I supported previous data and indicated that the program was effective in helping the participants increase the frequency of adaptive responses in combination with head control and the length of such control. The results of Study II showed that the raters found the effects of the new program more positive than those of other intervention conditions and also considered such program a useful complement to formal motor rehabilitation programs.

    Natalizumab (Tysabri(®)) is highly efficacious in controlling disease activity in relapsing multiple sclerosis (MS) patients. As it is one of the more recent therapies for MS, there remains a need for long-term safety and efficacy data of natalizumab in a clinical practice setting. The Tysabri observational program (TOP) is an open-label, multicenter, multinational, prospective observational study, aiming to recruit up to 6,000 patients with relapsing-remitting MS from Europe, Canada and Australia. The objectives of this study are to collect long-term safety and efficacy data on disease activity and disability progression. We report here the interim results of the 563 patients included in TOP between December 2007 and 2012 from Belgium. This patient cohort was older at baseline, had longer disease duration, higher neurological impairment, and a higher baseline annualized relapse rate, when compared to patients included in the pivotal phase III AFFIRM trial. Nevertheless, the efficacy of natalizumab was comparable. The annualized relapse rate on treatment was reduced by 90.70 % (p < 0.0001) with a cumulative probability of relapse of 26.87 % at 24 months. The cumulative probabilities of sustained disability improvement and progression at 24 months were 25.68 and 9.01 %, respectively. There were no new safety concerns over the follow-up period. Two cases of progressive multifocal leukoencephalopathy were diagnosed. Our results are consistent with other observational studies in the post-marketing setting.

With more than half of the 48 physicians registered in 1989 in the public sector working in the country's main hospital, nurses are responsible for most drug prescribing in the public health care system. At the primary care level, village health workers, most of whom are illiterate, are trained to prescribe a limited number of drugs. Numerous difficulties in this field prompted the Gambia to request assistance from the World Health Organization's Drug Action Program in reviewing the pharmaceutical sector and formulating a national drug policy. The Essential Drugs Program was introduced in 1984 with the main objectives of achieving regulatory control over drugs in the private sector and the availability of safe, effective, and affordable drugs in the public sector. Assessment of the impact and progress of the program indicate that the essential drugs concept in the country has helped resolve some serious problems. The Essential Drugs Program has substantially improved the efficacy and efficiency of pharmaceutical services in the Gambia. While the small size of the country can be an asset when implementing national programs, only very limited scope exists for training medical and other health workers. The national drug policy, the essential drugs list, the state supply system, the private sector, and the drug revolving funds project are discussed.

    The Health Education for Persons with Multiple Sclerosis (HEMS) program was developed in response to the need for interventions aimed at increasing physical activity for individuals with Multiple Sclerosis (MS). It was developed and evaluated using Drum and colleagues (2009) guidelines for implementing health promotion programs for individuals with disabilities. The purpose of this feasibility study is to describe the development, implementation, and evaluation of the HEMS program. Thirteen individuals with MS completed the 8-week health education program. A mixed method approach for evaluation was implemented (i.e., survey and focus groups). Process and resource feasibility demonstrated that over half of the participants attended at least 80% of the weekly sessions. Focus group data provided valuable feedback for future iterations of the program including critiques on the delivery, content, and group support provided. Outcome evaluation showed increases in self-efficacy (survey), improvements in theoretical constructs (focus groups), and increased physical activity (focus groups). Results show that health promotion programs for persons with MS can improve physical activity and related constructs. Next steps will be to revise, implement, and reevaluate the HEMS program in a larger randomized control trial.

  13. Technical note: Calculation of standard errors of estimates of genetic parameters with the multiple-trait derivative-free restricted maximal likelihood programs.

    The multiple-trait derivative-free REML set of programs was written to handle partially missing data for multiple-trait analyses as well as single-trait models. Standard errors of genetic parameters were reported for univariate models and for multiple-trait analyses only when all traits were measured on animals with records. In addition to estimating (co)variance components for multiple-trait models with partially missing data, this paper shows how the multiple-trait derivative-free REML set of programs can also estimate SE by augmenting the data file when not all animals have all traits measured. Although the standard practice has been to eliminate records with partially missing data, that practice uses only a subset of the available data. In some situations, the elimination of partial records can result in elimination of all the records, such as one trait measured in one environment and a second trait measured in a different environment. An alternative approach requiring minor modifications of the original data and model was developed that provides estimates of the SE using an augmented data set that gives the same residual log likelihood as the original data for multiple-trait analyses when not all traits are measured. Because the same residual vector is used for the original data and the augmented data, the resulting REML estimators along with their sampling properties are identical for the original and augmented data, so that SE for estimates of genetic parameters can be calculated.

    It is the position of the American Dietetic Association (ADA), the Society for Nutrition Education (SNE), and the American School Food Service Association (ASFSA) that comprehensive nutrition services must be provided to all of the nation's preschool through grade twelve students. These nutrition services shall be integrated with a coordinated, comprehensive school health program and implemented through a school nutrition policy. The policy should link comprehensive, sequential nutrition education; access to and promotion of child nutrition programs providing nutritious meals and snacks in the school environment; and family, community, and health services' partnerships supporting positive health outcomes for all children. Childhood obesity has reached epidemic proportions and is directly attributed to physical inactivity and diet. Schools can play a key role in reversing this trend through coordinated nutrition services that promote policies linking comprehensive, sequential nutrition education programs, access to and marketing of child nutrition programs, a school environment that models healthy food choices, and community partnerships. This position paper provides information and resources for nutrition professionals to use in developing and supporting comprehensive school health programs. J Am Diet Assoc. 2003;103:505-514.

    To extend the assessment of technology-based programs for promoting stimulus choice and staff/caregiver calls or radio operation and text messaging. In Study I, the program involved a portable computer, commercial software, and a microswitch to allow a man with motor impairment and moderate intellectual disability to choose among preferred stimuli (e.g., songs and film clips) and persons to call. In Study II, the programs involved (a) a radio device and an electronic control unit or (b) a net-book computer and a global system for mobile communication. A woman with blindness and moderate intellectual disability used a microswitch to operate the radio or send and listen to text messages. The participants succeeded in using the technology-aided programs through simple microswitch activations involving partial hand closure (Study I) or hand pressure (Study II). Technology-based programs can provide persons with multiple disabilities relevant leisure and communication opportunities.

  16. Multiple ligand-binding properties of the lipocalin member chicken alpha1-acid glycoprotein studied by circular dichroism and electronic absorption spectroscopy: the essential role of the conserved tryptophan residue.

    Multiple ligand-binding properties of the 30-kDa chicken alpha(1)-acid glycoprotein (cAGP), a member of the lipocalin protein family, were investigated for the first time by using circular dichroism (CD) and UV/Vis absorption spectroscopy methods. By measuring induced CD (ICD) spectra, high-affinity binding (K(a) approximately 10(5)-10(6) M(-1)) of several drugs, dyes and natural compounds to cAGP was demonstrated including antimalarial agents (quinacrine, primaquine), phenotiazines (chlorpromazine, methylene blue), propranolol, non-steroidal antiinflammatory drugs (ketoprofen, diclofenac), tamoxifen, diazepam, tacrine, dicoumarol, cationic dyes (auramine O, thioflavine T, ethidium bromide), benzo[a]pyrene, L-thyroxine, bile pigments (bilirubin, biliverdin), alkaloids (piperine, aristolochic acid), saturated and unsaturated fatty acids. Analysis of the extrinsic CD spectra with the study of the covalently modified protein and CD displacement experiments revealed that a single Trp26 residue of cAGP conserved in the whole lipocalin family is part of the binding site, and it is essentially involved in the ligand-binding process via pi-pi stacking interaction resulting in the appearance of strong induced CD bands due to the non-degenerate intermolecular exciton coupling between the pi-pi* transitions of the stacked indole ring-ligand chromophore. The finding that cAGP is able to accommodate a broad spectrum of ligands belonging to different chemical classes suggests that its core beta-barrel cavity is unusually wide containing overlapping sub-sites. Significance of these new data in understanding of the ligand-binding properties of other lipocalins, especially that of human AGP, and potential practical applications are briefly discussed. Overall, cAGP serves as a simple, ultimate model to extend our knowledge on ligand-binding properties of lipocalins and to study the role of tryptophan residues in molecular recognition processes.

    Although malaria control programs have made rapid progress recently, they neglect important social and behavioral factors associated with the disease. Social, political, and cultural factors are involved in malaria control, and individuals in a community may be comfortable in behaving in ways that, to an outsider, may seem contrary to commonly held perceptions. Malaria control efforts can no longer afford to overlook the multidimensional human contexts that create and support varying notions of malaria and its prevention, treatment, and control. This study aimed to assess the knowledge and perceptions of malaria issues in the community, and to identify practices that support or hinder the progress of malaria control programs. A triangulation study involving individual interviews, focus group discussions, and observatory analysis between 2003 and 2010 at Lomahasha, a malarious community on the eastern border of Swaziland and Mozambique, was conducted. Results indicated that a high knowledge level and good perception of the disease were observed in the age group of < 40 years, contrary to those in higher age groups, among the Lomahasha community members. However, behavior of certain community groups includes practices that are not supportive of the national control program's aspirations, such as delay in seeking medical attention, staying outdoors until late, maintaining stagnant water in roadside excavations, and seeking medical assistance from wrong sources. Malpractices are more commonly observed among men, boys, and those who drink alcohol. This study suggests a thorough community diagnosis before all intervention programs for malaria control are instituted. Copyright © 2015. Published by Elsevier B.V.

    Pulmonary muscle weakness is common in ambulatory people with multiple sclerosis (MS) and may lead to deficits in mobility function. The purpose of this study was to examine the effect of a 10-week home-based exercise program using an inspiratory muscle threshold trainer (IMT) on the results of four lower-extremity physical performance tests in people with MS. The study design was a two-group (experimental-control), pretest-posttest study. Outcome measures consisted of pulmonary function measures including maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and maximal voluntary ventilation (MVV), and the following lower-extremity physical performance measures: the 6-Minute Walk (6MW) distance, gait velocity (GV), the Sit-to-Stand Test (SST), the Functional Stair Test (FST), and a balance test (BAL). A total of 46 ambulatory participants (Expanded Disability Status Scale [EDSS] score, 2.0–6.5) with MS were randomly assigned to an intervention group (mean EDSS score, 4.1) that received 10 weeks of home-based inspiratory muscle training or a nontreatment control group (mean EDSS score, 3.2). Of the original 46 participants, 20 intervention group participants and 19 control group participants completed the study. Compared with the control group, the intervention group made significantly greater gains in inspiratory muscle strength (P = .003) and timed balance scores (P = .008). A nonsignificant improvement in 6MW distance (P = .086) was also noted in the IMT-trained group as compared with the control group. This is the first study directly linking improvement in respiratory function to improvement in physical performance function in people with mild-to-moderate disability due to MS. PMID:24453703

    Leading multiple sclerosis (MS) therapies have patient support programs (PSPs) aimed at improving patients' lives. There is limited knowledge about what drives patient satisfaction with PSPs and little evidence about its impact on patient-reported health status or health-related quality of life. The aims of this study were to evaluate patient needs and the PSP's role in meeting those needs; understand the drivers of PSP satisfaction and loyalty; and assess whether a MS PSP provides quantifiable, incremental benefit to patients, as measured by patient-reported health status, health state utility, and/or health-related quality of life. An Internet survey was conducted among 1,123 adult German MS patients currently enrolled in Bayer's German BETAPLUS PSP. Health status, health state utility, and health-related quality of life were measured using the EQ-5D Visual Analog Scale, the EQ-5D Index, and Short Form-12 Health Survey, respectively. MS patient needs vary by disease severity, duration of disease, and gender. Patients with greater self-reported needs and lower health status, health state utility, and health-related quality of life value and use the PSP more than other patients. Drivers of PSP satisfaction include use of patient hotline, nurse telephone calls, and mail education. Patients estimate that their health status would be 15 points lower if the PSP ceased to exist (translating to 0.15 on the time trade-off utility scale). This impact is significant, as it is nearly two times the minimally important difference. MS patients place inherent value on PSPs. From a patient's viewpoint, PSPs provide real incremental benefit in patient-reported health status at all stages of MS.

    Background It is widely recognised that deficiencies in fetal surveillance practice continue to contribute significantly to the burden of adverse outcomes. This has prompted the development of evidence-based clinical practice guidelines by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists and an associated Fetal Surveillance Education Program to deliver the associated learning. This article describes initial steps in the validation of a corresponding multiple-choice assessment of the relevant educational outcomes through a combination of item response modelling and expert judgement. Methods The Rasch item response model was employed for item and test analysis and to empirically derive the substantive interpretation of the assessment variable. This interpretation was then compared to the hierarchy of competencies specified a priori by a team of eight subject-matter experts. Classical Test Theory analyses were also conducted. Results A high level of agreement between the hypothesised and derived variable provided evidence of construct validity. Item and test indices from Rasch analysis and Classical Test Theory analysis suggested that the current test form was of moderate quality. However, the analyses made clear the required steps for establishing a valid assessment of sufficient psychometric quality. These steps included: increasing the number of items from 40 to 50 in the first instance, reviewing ineffective items, targeting new items to specific content and difficulty gaps, and formalising the assessment blueprint in light of empirical information relating item structure to item difficulty. Conclusion The application of the Rasch model for criterion-referenced assessment validation with an expert stakeholder group is herein described. Recommendations for subsequent item and test construction are also outlined in this article. PMID:19402898

    The Unique Minds Program (Stern, Unique Minds Program, 1999) addresses the socio-emotional needs of children with learning disabilities (LD) and their families. Children and their parents work together in a multiple family group to learn more about LD and themselves as people with the capacity to solve problems in a collaborative way, including problems in family school relationships. This article reports the cultural adaptation of the program for use in Spain and findings from a feasibility study involving three multiple family groups and a total of 15 children and 15 mothers, using a pre-post design. This Spanish adaptation of the program is called "Mentes Únicas". Standardized outcome measures indicated an overall statistically significant decrease in children's self-rated maladjustment and relationship difficulties by the end of the program. Improvements were endorsed by most mothers, although they were not always recognized by the children's teachers. The program had a high level of acceptability: Mothers and children felt safe, understood, and helped throughout the sessions. The efficacy of the adapted intervention for the context of Spain remains to be tested in a more rigorous study. © 2016 Family Process Institute.

  4. An inexact fuzzy-chance-constrained two-stage mixed-integer linear programming approach for flood diversion planning under multiple uncertainties

    In this study, an inexact fuzzy-chance-constrained two-stage mixed-integer linear programming (IFCTIP) approach is developed for flood diversion planning under multiple uncertainties. A concept of the distribution with fuzzy boundary interval probability is defined to address multiple uncertainties expressed as integration of intervals, fuzzy sets and probability distributions. IFCTIP integrates the inexact programming, two-stage stochastic programming, integer programming and fuzzy-stochastic programming within a general optimization framework. IFCTIP incorporates the pre-regulated water-diversion policies directly into its optimization process to analyze various policy scenarios; each scenario has different economic penalty when the promised targets are violated. More importantly, it can facilitate dynamic programming for decisions of capacity-expansion planning under fuzzy-stochastic conditions. IFCTIP is applied to a flood management system. Solutions from IFCTIP provide desired flood diversion plans with a minimized system cost and a maximized safety level. The results indicate that reasonable solutions are generated for objective function values and decision variables, thus a number of decision alternatives can be generated under different levels of flood flows.

    A relationship enrichment program involves family therapy with psychosocial training to improve relationship skills. This study was conducted to determine the effect of a couples' relationship enrichment program on marital relationship quality. This quasi-experimental study was conducted in 2016 with 80 spouses of patients, all members of the Multiple Sclerosis (MS) Center in Zahedan, Iran. The participants were randomly assigned to two groups: an intervention and a control group, each of which comprised 40 participants. The Perceived Relationship Quality Components questionnaire was used to collect the required data. After five-session couples' relationship enrichment program, the mean total marital relationship quality score and all the subscale scores except the love subscale score in the intervention group were significantly greater than those in the control group. Application of the program is recommended to increase the quality of marital relationships for spouses of patients with MS, as they are the most important sources of support for patients with MS.

    Multiple sclerosis (MS) is a chronic and debilitating disease of the central nervous system that affects more than 570,000 persons in the United States and 2.3 million worldwide. Since most individuals experience initial symptoms between the ages of 20 and 40 years, MS can have a significant effect on health care consumption, quality of life, productivity, and employment over the long-term disease course. Opportunities exist to better understand how benefit design and other nonclinical factors can affect health care delivery and associated costs. To observe and report variances in health care consumed for the treatment of MS in patients enrolled in privately (commercial) and publicly (Medicaid) funded health insurance programs. In a retrospective analysis using Havas Gemini's proprietary MS Benchmarks Disease-Modeling Process and IMS LifeLink Health Plan Claims and Longitudinal Prescriptions databases, integrated medical and pharmacy claims data were analyzed to select patients with a diagnosis of MS during the 2012 calendar year. Comorbidities were determined using ICD-9-CM codes present on medical claims. Prescription drug use was evaluated by pharmacy claims and drug-specific billing codes. 19,984 patients with MS were identified-18,269 from commercial payers and 1,715 from Medicaid. Although total annual costs related to the care of MS for the groups reflected a relatively small difference ($31,107 commercial; $33,344 Medicaid), costs associated with specific service categories varied greatly. Pharmacy costs were considerably less in the Medicaid group; however, inpatient and emergency room costs were as much as 5 times higher. Overall use of disease-modifying treatments (DMTs) in the Medicaid group was seen in 32.5% of patients and 52.1% in the commercial patient group. Thus, lower pharmacy costs in the Medicaid group were possibly related to lesser use of DMTs among that group of patients. This analysis illustrates that notable variances exist in consumption

    Persons with multiple disabilities, including pervasive motor impairment, may have problems controlling even small responses (e.g., vocal emissions, finger movements, or prolonged eyelid closures) within time-sensitive situations, such as those involved in choice programs. Recent research has indicated that smile expressions can be used as functional choice responses for some of these persons. The present two studies were aimed at assessing the smile response for a child with congenital multiple disabilities and a tongue response for a post-coma man who had recovered his consciousness but presented with pervasive multiple disabilities. The first of the two studies represented a research extension (i.e., a new case with a slightly adapted microswitch technology) concerning the smile response, which had recently been evaluated with few other cases. The second study represented a new effort to assess the tongue response within a choice program and for a post-coma man with multiple disabilities. The results showed that the participants used the smile and the tongue responses successfully while they were apparently unsuccessful in using a slight head/chin movement response. Their choice behavior focused reliably on preferred stimuli and avoided non-preferred stimuli. Implications of the results are discussed.

    Male sterility is important for hybrid seed production. Pollen development is regulated by a complex network. We previously showed that knockout of bHLH142 in rice (Oryza sativa) causes pollen sterility by interrupting tapetal programmed cell death (PCD) and bHLH142 coordinates with TDR to modulate the expression of EAT1. In this study, we demonstrated that overexpression of bHLH142 (OE142) under the control of the ubiquitin promoter also leads to male sterility in rice by triggering the premature onset of PCD. Protein of bHLH142 was found to accumulate specifically in the OE142 anthers. Overexpression of bHLH142 induced early expression of several key regulatory transcription factors in pollen development. In particular, the upregulation of EAT1 at the early stage of pollen development promoted premature PCD in the OE142 anthers, while its downregulation at the late stage impaired pollen development by suppressing genes involved in pollen wall biosynthesis, ROS scavenging and PCD. Collectively, these events led to male sterility in OE142. Analyses of related mutants further revealed the hierarchy of the pollen development regulatory gene network. Thus, the findings of this study advance our understanding of the central role played by bHLH142 in the regulatory network leading to pollen development in rice and how overexpression of its expression affects pollen development. Exploitation of this novel functionality of bHLH142 may confer a big advantage to hybrid seed production. PMID:28769961

    Many pathogens, including Plasmodium spp., exploit the interaction of programmed death-1 (PD-1) with PD-1-ligand-1 (PD-L1) to "deactivate" T cell functions, but the role of PD-L2 remains unclear. We studied malarial infections to understand the contribution of PD-L2 to immunity. Here we have shown that higher PD-L2 expression on blood dendritic cells, from Plasmodium falciparum-infected individuals, correlated with lower parasitemia. Mechanistic studies in mice showed that PD-L2 was indispensable for establishing effective CD4(+) T cell immunity against malaria, because it not only inhibited PD-L1 to PD-1 activity but also increased CD3 and inducible co-stimulator (ICOS) expression on T cells. Importantly, administration of soluble multimeric PD-L2 to mice with lethal malaria was sufficient to dramatically improve immunity and survival. These studies show immuno-regulation by PD-L2, which has the potential to be translated into an effective treatment for malaria and other diseases where T cell immunity is ineffective or short-lived due to PD-1-mediated signaling.

    Patients with refractory severe hypertriglyceridemia are at risk of pancreatitis and cardiovascular disease. The role of individualized nutrition therapy in these patients independent of pharmaceutical treatment has not been documented. To document the effect of nutrition intervention on severe hypertriglyceridemia regardless of medication status or prior nutrition counseling. Outcomes of new patients with triglycerides ≥ 500 mg/dL presenting to a Lipid Management Program over a 6-year period were tracked. Patients received comprehensive laboratory assessment, nutrition assessment, and initiation of an individualized diet intervention before seeing the lipidologist. Clinical and behavioral outcomes were recorded. In all, 168 patients (117 men; mean age, 49.03 ± 11.22 years; body mass index, 32.61 ± 5.85 kg/m(2); 110 (65.5%) on lipid-lowering medications) returned for assessment of nutrition intervention. Triglycerides were reduced from median (interquartile range) 961.5 (611.5-1785.3) to 493.0 (337-736.3) mg/dL (P < .0001 for log transformation of triglycerides). There was no difference in median percentage reduction in triglycerides after nutrition intervention between those not on lipid-lowering medication, on a fibric acid derivative, on other lipid-lowering medication, or on a combination of lipid-lowering medications (P = .376) in a median (interquartile range) of 5 (3-7) weeks. Effect was independent of prior nutrition counseling (P = .260). Reported percentage fat in the diet at second visit correlated with log-transformed triglycerides achieved, independent of initial triglycerides level (r = 0.290; P = .001). Individualized nutrition therapy results in changes in eating behavior and reductions in triglyceride levels in patients with refractory severe hypertriglyceridemia independent of lipid-lowering medication(s) and prior nutrition counseling.

    A computer program was written to produce 6 different types of water-quality diagrams--Piper, Stiff, pie, X-Y, boxplot, and Piper 3-D--from the same file of input data. The Piper 3-D diagram is a new method that projects values from the surface of a Piper plot into a triangular prism to show how variations in chemical composition can be related to variations in other water-quality variables. This program is an analytical tool to aid in the interpretation of data. This program is interactive, and the user can select from a menu the type of diagram to be produced and a large number of individual features. Alternatively, these choices can be specified in the data file, which provides a batch mode for running the program. The program does not display water-quality diagrams directly; plots are written to a file. Four different plot- file formats are available: device-independent metafiles, Adobe PostScript graphics files, and two Hewlett-Packard graphics language formats (7475 and 7586). An ASCII data-table file is also produced to document the computed values. This program is written in Fortran '77 and uses graphics subroutines from either the PRIOR AGTK or the DISSPLA graphics library. The program has been implemented on Prime series 50 and Data General Aviion computers within the USGS; portability to other computing systems depends on the availability of the graphics library.

    Compelling evidence supporting the benefits of social engagement in older adults has been increasingly discussed. However, knowledge regarding an intergenerational program is limited. Herein, we provide a targeted review of intergenerational programs by focusing on our novel interventional program, Research on Productivity through Intergenerational Sympathy. The Research on Productivity through Intergenerational Sympathy program is an intergenerational picture-book reading program launched in 2004. Participants were involved a 3-month intensive weekly training seminar comprising classes about book selection, reading techniques and basic knowledge of children's school life. Subsequently, they participated in group activities that involved playing a hand game, and reading picture books to children at kindergartens, elementary schools and public childcare centers, once every 1-2 weeks. The Research on Productivity through Intergenerational Sympathy program has shown improvement of physical and psychological functioning of older adults and healthy upbringing of children. Similarly, Experience Corps - designed to train and place volunteers in participating elementary schools for an academic year during which time they assist teachers - also showed positive effects for older adults' health status and the psychological/academic success of young children in the USA. Health promotion efforts for older adults must support social policy for the creation of meaningful service programs for older adults on a large social scale. As such, an intergenerational program based on the concept of social capital, defined as "features of social organization, such as trust, norms and networks, that can improve the efficacy of society by facilitating coordinated actions," is an effective and sustainable program for health promotion among older adults. © 2016 Japan Geriatrics Society.

    We evaluated the efficacy of blastocyst transfer in decreasing the incidence of high-order multiple gestations after in vitro fertilization. We conducted a retrospective analysis of 218 patients who were undergoing in vitro fertilization and by our criteria of three 8-cell embryos on day 3 could receive either a day 3 transfer of cleaved embryos or a day 5 transfer of blastocysts. Ongoing pregnancy rates, implantation rates (determined by the total number of visualized gestational sacs), and multiple pregnancy rates were compared between the 2 groups. Respective day 3 and day 5 ongoing pregnancy rates (61% and 51%) and implantation rates (35% and 33%) were not significantly different. There were 9 triplet or higher gestations in the day 3 group and 0 in the day 5 group. Blastocyst transfer can be used to reduce the number of embryos transferred and the resultant incidence of high-order multiple pregnancies while maintaining high pregnancy rates.

    2013-10-01

    I argue here that we have succeeded in localizing an essential memory trace for a basic form of associative learning and memory--classical conditioning of discrete responses learned with an aversive stimulus--to the anterior interpositus nucleus of the cerebellum. We first identified the entire essential circuit, using eyelid conditioning as the model system, and used reversible inactivation, during training, of critical structures and pathways to localize definitively the essential memory trace. In recognition of the 30th anniversary of Behavioral Neuroscience, I highlight 1 paper (Tracy, Thompson, Krupa, & Thompson, 1998) that was particularly significant for the progress of this research program. In this review, I present definitive evidence that the essential memory trace for eyelid conditioning is localized to the cerebellum and to no other part of the essential circuit, using electrical stimulation of the pontine nuclei-mossy fibers projecting to the cerebellum as the conditional stimulus (CS; it proved to be a supernormal stimulus resulting in much faster learning than with any peripheral CS) and using an electrical stimulus to the output of the cerebellum as a test, which did not change. Pontine patterns of projection to the cerebellum were confirmed with retrograde labeling techniques.

    Behavioral trajectories during middle childhood are predictive of consequential outcomes later in life (e.g., substance abuse, violence). Social and emotional learning (SEL) programs are designed to promote trajectories that reflect both growth in positive behaviors and inhibited development of negative behaviors. The current study used growth mixture models to examine effects of the Positive Action (PA) program on behavioral trajectories of social-emotional and character development (SECD) and misconduct using data from a cluster-randomized trial that involved 14 schools and a sample of predominately low-income, urban youth followed from 3rd through 8th grade. For SECD, findings indicated that PA was similarly effective at improving trajectories within latent classes characterized as "high/declining" and "low/stable". Favorable program effects were likewise evident to a comparable degree for misconduct across observed latent classes that reflected "low/rising" and "high/rising" trajectories. These findings suggest that PA and perhaps other school-based universal SEL programs have the potential to yield comparable benefits across subgroups of youth with differing trajectories of positive and negative behaviors, making them promising strategies for achieving the intended goal of school-wide improvements in student outcomes.

    To evaluate a skilled birth attendant (SBA) training program in a neglected population on the Thai-Myanmar border, we used multiple methods to show that refugee and migrant health workers can be given effective training in their own environment to become SBAs and teachers of SBAs. The loss of SBAs through resettlement to third countries necessitated urgent training of available workers to meet local needs. All results were obtained from student records of theory grades and clinical log books. Qualitative evaluation of both the SBA and teacher programs was obtained using semi-structured interviews with supervisors and teachers. We also reviewed perinatal indicators over an eight-year period, starting prior to the first training program until after the graduation of the fourth cohort of SBAs. Four SBA training programs scheduled between 2009 and 2015 resulted in 79/88 (90%) of students successfully completing a training program of 250 theory hours and 625 supervised clinical hours. All 79 students were able to: achieve pass grades on theory examination (median 80%, range [70-89]); obtain the required clinical experience within twelve months; achieve clinical competence to provide safe care during childbirth. In 2010-2011, five experienced SBAs completed a train-the-trainer (TOT) program and went on to facilitate further training programs. Perinatal indicators within Shoklo Malaria Research Unit (SMRU), such as place of birth, maternal and newborn outcomes, showed no significant differences before and after introduction of training or following graduate deployment in the local maternity units. Confidence, competence and teamwork emerged from qualitative evaluation by senior SBAs working with and supervising students in the clinics.

    Background There is a growing need to offer persons with multiple sclerosis (PwMS) possibilities for self-management and to integrate multidisciplinary health data. In 2009–2014 we developed a patient-reported outcome based, interactive, web-based program (MSmonitor) for (self-)monitoring, self-management and integrated, multidisciplinary care in MS. Methods The notions underlying the MSmonitor concept and the program’s elements are described. We analyze MSmonitor’s role in the self-management of fatigue by retrospective comparison of fatigue and health-related quality of life (HRQoL) before and after usage of specific elements of MSmonitor, and by a correlative analysis between frequency of usage and fatigue change. Results After a step-wise development the program comprises six validated questionnaires: Multiple Sclerosis Impact Profile, Modified Fatigue Impact Scale-5 items (MFIS-5), Hospital Anxiety and Depression Scale, Multiple Sclerosis Quality of Life-54 items, and the 8-item Leeds Multiple Sclerosis Quality of Life (LMSQoL) questionnaires; two inventories: Medication and Adherence Inventory, Miction Inventory; two diaries: Activities Diary, Miction Diary; and two functionalities: e-consult and personal e-logbook. The program is now used in 17 hospitals by 581 PwMS and their neurologists, MS nurses, physical therapists, rehabilitative doctors, continence nurses, and family doctors. Those PwMS (N=105) who used the LMSQoL and MFIS-5 questionnaires at least twice in a period of up to 6 months, showed improved HRQoL (P<0.026). In the subgroup (N=56) who had also used the Activities Diary twice or more, the frequency of diary usage correlated modestly with the degree of fatigue improvement (r=0.292; P=0.028). Conclusion MSmonitor is an interactive web-based program for self-management and integrated care in PwMS. Pilot data suggest that the repeated use of the short MFIS-5 and LMSQoL questionnaires is associated with an increase in HRQoL, and that a

    Health-compromising behaviors among survivors of childhood cancer may increase their risks of cancer recurrence and the onset of chronic disease in adulthood. Regardless of whether such behaviors occur singly or in combination with one another, multiple behavioral risk factors must be identified and addressed early to promote better health outcomes within this special population. Adolescent survivors may be especially vulnerable, as reported rates of smoking and other risky behaviors are at or near levels of their healthy peers. The psychological literature suggests stress may play a role in risk behavior initiation and maintenance, including multiple behavioral risks, and that adolescent survivors are stress-prone. This report focuses on the prevalence and co-occurrence of three behavioral risk factors (cigarette use, insufficient physical activity, and non-adherence to sun protection recommendations) and describes stress-health behavior relationships in this special population. All patients in this study (n = 75) were adolescent survivors of childhood cancer and completed a baseline assessment of their health behaviors and stress as part of a randomized controlled trial of health promotion. Twenty-eight percent of the patients reported one of three risk factors, 12% reported two of three risk factors, and 7% reported all three risk factors. Non-adherence to sun protection was the single most common risk factor; physical inactivity and non-adherent sun protection were the most common co-occurring risk factors. Greater age and stress were significantly associated with the presence of more behavioral risk factors. The evidence suggests interventions to reduce multiple health-compromising behaviors in these patients are warranted, and that efforts to address these patients' personal and family stress levels are important as well.

    For the evaluation of both the adequacy of intakes and the risk of excessive intakes of micronutrients, all potential sources should be included. In addition to micronutrients naturally present in foods, micronutrients can also be derived from fortified foods and dietary supplements. In the estimation of the habitual intake, this may cause specific challenges such as multimodal distributions and heterogeneous variances between the sources. We present the Statistical Program to Assess Dietary Exposure (SPADE) that was developed to cope with these challenges in one single program. Similar to other methods, SPADE can model habitual intake of daily and episodically consumed dietary components. In addition, SPADE has the option to model habitual intake from dietary supplements. Moreover, SPADE offers models to estimate habitual intake distributions from different sources (e.g., foods and dietary supplements) separately and adds these habitual intakes to get the overall habitual intake distribution. The habitual intake distribution is modeled as a function of age, and this distribution can directly be compared with cutoff values to estimate the proportion above or below. Uncertainty in the habitual intake distribution and in the proportion below or above a cutoff value is quantified with ready-for-use bootstrap and provides 95% CIs. SPADE is implemented in R and is freely available as an R package called SPADE.RIVM. The various features of SPADE are illustrated by the estimation of the habitual intake distribution of folate and folic acid for women by using data from the Dutch National Food Consumption Survey 2007-2010. The results correspond well with the results of existing programs. SPADE offers new features to existing programs to estimate the habitual intake distribution because it can handle many different types of modeling with the first-shrink-then-add approach. © 2014 American Society for Nutrition.

  14. Reconciling the multiple objectives of prison diversion programs for drug offenders: evidence from Kansas' Senate Bill 123.

    PubMed

    Stemen, Don; Rengifo, Andres F

    2011-12-01

    In recent years, several states have created mandatory prison-diversion programs for felony drug possessors. These programs have both individual-level goals of reducing recidivism rates and system-level goals of reducing prison populations. This study examines the individual level and system level impact of Kansas' Senate Bill 123 (SB 123), which created mandatory probation/treatment sentences for felony drug possessors. A nonrandomized quasi-experimental design was used to evaluate the recidivism rates of drug possessors sentenced to SB 123 relative to drug possessors sentenced to standard probation, intensive probation, or prison. Propensity score matching techniques were used to identify comparison groups. Changes in probabilities of prison sentences preimplementation and postimplementation were used to assess changes in prison admissions and prison populations. The treatment group included all eligible drug possessors sentenced to SB 123 between November 1, 2003, and October 31, 2006. The comparison groups included all eligible drug possessors sentenced to standard probation, intensive probation, or prison during the same time period. Arrests, violations, revocation resulting in a prison sentence, and reconviction resulting in a prison sentence within 24 months of risk in the community served as the key individual-level outcome measures. Prison admissions and bed days served as the key system-level outcome measures. At the individual level, SB 123 increased likelihood of recidivism compared to standard probation and had no significant effect compared to intensive probation or prison. At the system level, SB 123 diverted offenders from prison at sentencing but only marginally reduced prison admissions or saved bed days. Conflicting impacts are a consequence of program design-eligibility requirements diverting probation-bound offenders, mandatory sentencing requiring the same diversion sentence for all offenders, and diversion sentences longer than those imposed

    Context: Recognition of the importance of informatics to the practice of pathology has surged. Training residents in pathology informatics has been a daunting task for most residency programs in the United States because faculty often lacks experience and training resources. Nevertheless, developing resident competence in informatics is essential for the future of pathology as a specialty. Objective: To develop and deliver a pathology informatics curriculum and instructional framework that guides pathology residency programs in training residents in critical pathology informatics knowledge and skills, and meets Accreditation Council for Graduate Medical Education Informatics Milestones. Design: The College of American Pathologists, Association of Pathology Chairs, and Association for Pathology Informatics formed a partnership and expert work group to identify critical pathology informatics training outcomes and to create a highly adaptable curriculum and instructional approach, supported by a multiyear change management strategy. Results: Pathology Informatics Essentials for Residents (PIER) is a rigorous approach for educating all pathology residents in important pathology informatics knowledge and skills. PIER includes an instructional resource guide and toolkit for incorporating informatics training into residency programs that vary in needs, size, settings, and resources. PIER is available at http://www.apcprods.org/PIER (accessed April 6, 2016). Conclusions: PIER is an important contribution to informatics training in pathology residency programs. PIER introduces pathology trainees to broadly useful informatics concepts and tools that are relevant to practice. PIER provides residency program directors with a means to implement a standardized informatics training curriculum, to adapt the approach to local program needs, and to evaluate resident performance and progress over time.

    Study I used typical microswitch-cluster programs to promote adaptive responding (i.e., object manipulation) and reduce inappropriate head or head-trunk forward leaning with a boy and a woman with multiple disabilities. Optic, tilt, and vibration microswitches were used to record their adaptive responses while optic and tilt microswitches monitored their posture. The study included an ABB(1)AB(1) sequence, in which A represented baseline phases, B represented an intervention phase in which adaptive responses were always followed by preferred stimulation, and B(1) represented intervention phases in which the adaptive responses led to preferred stimulation only if the inappropriate posture was absent. Study II assessed a non-typical, new microswitch-cluster program to promote two adaptive responses (i.e., mouth cleaning to reduce drooling effects and object assembling) with a man with multiple disabilities. Initially, the man received preferred stimulation for each cleaning response. Then, he received stimulation only if mouth cleaning was preceded by object assembling. The results of Study I showed that both participants had large increases in adaptive responding and a drastic reduction in inappropriate posture during the B(1) phases and a 2-week post-intervention check. The results of Study II showed that the man learned to control drooling effects through mouth cleaning and used object assembling to extend constructive engagement and interspace cleaning responses functionally. The practical implications of the findings are discussed.

    The present three single-case studies assessed the effectiveness of technology-based programs to help three persons with multiple disabilities exercise adaptive response schemes independently. The response schemes included (a) left and right head movements for a man who kept his head increasingly static on his wheelchair's headrest (Study I), (b) left- and right-arm movements for a woman who tended to hold both arms/hands tight against her body (Study II), and (c) touching object cues on a computer screen for a girl who rarely used her residual vision for orienting/guiding her hand responses. The technology involved microswitches/sensors to detect the response schemes and a computer/control system to record their occurrences and activate preferred stimuli contingent on them. Results showed large increases in the response schemes targeted for each of the three participants during the intervention phases of the studies. The importance of using technology-based programs as tools for enabling persons with profound and multiple disabilities to practice relevant responses independently was discussed.

    Millions of children die every year before they reach the age of 5 years, of conditions largely treatable with existing medicines. The WHO Model List of Essential Medicines was launched in 1977 to make the most necessary drugs available to populations whose basic health needs could not be met by the existing supply system. During the first 30 years of the Model List of Essential Medicines, children's needs were not systematically considered. After adoption of the 'Better medicines for children' resolution by the World Health Assembly, things changed. The first WHO Model List of Essential Medicines for Children was drawn up by a Paediatric Expert Subcommittee and adopted in October 2007. The most recent, 4th Model List of Essential Medicines for Children was adopted in 2013. Data from country surveys show that access to essential medicines for children is still generally poor; much more work is needed.

    Transient receptor potential ankyrin 1 (TRPA1) is a calcium-permeable non-selective cation channel that is activated by various noxious or irritant substances in nature, including spicy compounds. Many TRPA1 chemical activators have been reported; however, only limited information is available regarding the amino acid residues that contribute to the activation by non-electrophilic activators, whereas activation mechanisms by electrophilic ligands have been well characterized. We used intracellular Ca2+ measurements and whole-cell patch clamp recordings to show that eudesmol, an oxygenated sesquiterpene present at high concentrations in the essential oil of hop cultivar Hallertau Hersbrucker, could activate human TRPA1. Gradual activation of inward currents with outward rectification by eudesmol was observed in human embryonic kidney-derived 293 cells expressing human TRPA1. This activation was completely blocked by a TRPA1-specific inhibitor, HC03–0031. We identified three critical amino acid residues in human TRPA1 in putative transmembrane domains 3, 4, and 5, namely threonine at 813, tyrosine at 840, and serine at 873, for activation by β-eudesmol in a systematic mutational study. Our results revealed a new TRPA1 activator in hop essential oil and provide a novel insight into mechanisms of human TRPA1 activation by non-electrophilic chemicals. PMID:25525269

    This paper addresses the factors involved in effectively implementing a world-class program/project management information system funded by multiple nations. Along with many other benefits, investing in and utilizing such systems improves delivery and drive accountability for major expenditures. However, there are an equally large number of impediments to developing and using such systems. To be successful, the process requires a dynamic combining of elements and strategic sequencing of initiatives. While program/project-management systems involve information technologies, software and hardware, they represent only one element of the overall system.. Technology, process, people and knowledge must all be integrated and working in concert with one another to assure a fully capable system. Major system implementations occur infrequently, and frequently miss established targets in relatively small organizations (with the risk increasing with greater complexity). The European Bank of Reconstruction (EBRD) is midway through just such an implementation. The EBRD is using funds from numerous donor countries to sponsor development of an overarching program management system. The system will provide the Russian Federation with the tools to effectively manage prioritizing, planning, and physically decommissioning assets{sub i}n northwest Russia to mitigate risks associated the Soviet era nuclear submarine program. Project-management delivery using world-class techniques supported by aligned systems has been proven to increase the probability of delivering on-time and on-budget, assuring those funding such programs optimum value for money. However, systems deployed to manage multi-laterally funded projects must be developed with appropriate levels of consideration given to unique aspects such as: accommodation of existing project management methods, consideration for differences is management structures and organizational behaviors, incorporation of unique strengths, and

    To describe the design and present the baseline findings of the evaluation study of 'Paesaggi di Prevenzione', a school-based prevention program tackling smoking, alcohol misuse, dietary risks, and physical inactivity in 12- to 14-year-olds. The program was implemented from January 2011 to April 2012 in Emilia-Romagna, Italy, and comprised classroom activities and school-wide policies. A two-arm cluster randomized controlled trial was designed. Schools were the units of randomization and were matched by socioeconomic status, size, and type. Data from 4700 middle school students and 2952 high school students were collected anonymously from October to December 2010. Past-30-day smoking prevalence was 1.9% among middle school students and 20.8% among high school students. Past-30-day prevalence of alcohol intoxication was 2.2% among middle school students and 11.4% among high school students. A total of 39.7% of middle school students and 48.0% of high school students drank sugar-sweetened beverages four or more times per week; 7.5% of middle school students and 7.1% of high school students had intense physical activity every day. This study seems adequately powered and baseline variables appear evenly distributed between study groups. Findings are in line with those of the WHO Health Behaviour in School-Aged Children study.

    Tissue transglutaminase (tTG) and keratinocyte transglutaminase (kTG), as well as the cross-linked envelopes (CLE) that they form, have been associated with squamous differentiation and programmed cell death in epithelial cells. When interferon-beta (IFN-beta) was used to stimulate differentiation and programmed cell death in the human lung cancer cell lines NCI-H596 and NCI-H226, the cells underwent a decrease in cellular density. In NCI-H596 IFN-beta caused an increase in kTG activity and DNA fragmentation in the lower density cells, which were significantly slower growing than control cells. However, in the higher density cells, which were only slightly slower growing than control cells, IFN-beta caused an increase in tTG activity and CLE competence. Dual-parameter flow cytometry demonstrated that IFN-beta-induced squamous differentiation preceded programmed cell death. Treatment of NCI-H596 cells with monodansylcadaverine, a transglutaminase inhibitor, prevented the increase in CLE competence, but did not inhibit DNA fragmentation. These results suggest that IFN-beta can induce NCI-H596 cells to enter multiple cell death pathways and that these pathways are not only differentiation related, but may also be growth driven.

    Background. Balance and walking impairments are frequent in people with multiple sclerosis (MS). Objective. The aim was to investigate the effects of a group-based balance exercise program targeting core stability, dual tasking, and sensory strategies (CoDuSe) on balance, postural sway, walking, perceived walking limitations, and balance confidence. Design. A single-blinded randomized multicenter trial. No intervention was given to controls. Participants. People with MS able to walk 100 meters but unable to maintain tandem stance ≥30 seconds. Eighty-seven participants were randomized to intervention or control. Intervention. The 60-minute CoDuSe group program, twice weekly for seven weeks, supervised by physical therapists. Measurements. Primary outcome was dynamic balance (Berg Balance Scale (BBS)). Secondary outcomes were postural sway, walking (Timed-Up and Go test; Functional Gait Assessment (FGA)), MS Walking Scale, and Activities-specific Balance Confidence (ABC) Scale. Assessments were performed before and after (week 8) the intervention. Results. 73 participants fulfilled the study. There were significant differences between the intervention and the control groups in change in the BBS and in the secondary measures: postural sway with eyes open, FGA, MS Walking Scale, and ABC scale in favor of the intervention. Conclusions. The seven-week CoDuSe program improved dynamic balance more than no intervention. PMID:28042485

    Abstract microRNAs (miRNAs) are abundantly expressed in development where they are critical determinants of cell differentiation and phenotype. Accordingly miRNAs are essential for normal skeletal development and chondrogenesis in particular. However, the question of which miRNAs are specific to the chondrocyte phenotype has not been fully addressed. Using microarray analysis of miRNA expression during mesenchymal stem cell chondrogenic differentiation and detailed examination of the role of essential differentiation factors, such as SOX9, TGF‐β, and the cell condensation phase, we characterize the repertoire of specific miRNAs involved in chondrocyte development, highlighting in particular miR‐140 and miR‐455. Further with the use of mRNA microarray data we integrate miRNA expression and mRNA expression during chondrogenesis to underline the particular importance of miR‐140, especially the ‐5p strand. We provide a detailed identification and validation of direct targets of miR‐140‐5p in both chondrogenesis and adult chondrocytes with the use of microarray and 3′UTR analysis. This emphasizes the diverse array of targets and pathways regulated by miR‐140‐5p. We are also able to confirm previous experimentally identified targets but, additionally, identify a novel positive regulation of the Wnt signaling pathway by miR‐140‐5p. Wnt signaling has a complex role in chondrogenesis and skeletal development and these findings illustrate a previously unidentified role for miR‐140‐5p in regulation of Wnt signaling in these processes. Together these developments further highlight the role of miRNAs during chondrogenesis to improve our understanding of chondrocyte development and guide cartilage tissue engineering.

    Objective. To assess the multiple mini-interview (MMI) as an admission tool for a satellite campus. Methods. In 2013, the MMI was implemented as part of a new admissions model at the UNC Eshelman School of Pharmacy. From fall 2013 to spring 2015, 73 candidates were interviewed by 15 raters on the satellite campus in Asheville, North Carolina. A many-facet Rasch measurement (MFRM) with three facets was used to determine the variance in candidate ratings attributable to rater severity, candidate ability, and station difficulty. Candidates were surveyed to explore their perceptions of the MMI. Results. Rasch measures accounted for 48.3% of total variance in candidate scores. Rater severity accounted for 9.1% of the variance, and candidate ability accounted for 36.2% of the variance. Eighty percent of survey respondents (strongly) agreed that interviewers got to know them based on questions they answered.Conclusion. This study suggests that the MMI is a useful and valid tool for candidate selection at a satellite campus.

    Background: Multiple sclerosis (MS) is the most common autoimmune disorder of the central nervous system with profound effects on patients’ independence and self-efficacy. Then, it is still questionable whether self-management programs in patients with MS affect the patients’ self-efficacy. Objectives: The present study aimed to investigate the effect of a self-management program plus regular follow-up on self-efficacy in patients with MS. Patients and Methods: A quasi-experimental study was performed on 80 patients with relapsing remitting MS who were randomly allocated to an intervention (n = 40) and a control group (n = 40). The MS self-efficacy scale was completed before and after the intervention. The intervention group was divided into four small subgroups of ten. Then, each subgroup was invited to participate in four training sessions about self-management. During the two months after the self-management sessions, a weekly telephone follow-up was conducted for each patient in the intervention group. The control group did not receive any intervention other than routine care. Data were analyzed using SPSS 11.5. Descriptive statistics, Chi-square, and independent-samples t-testes were used to analyze the data. Results: No significant difference in mean scores of baseline self-efficacy was found between the control (52.90 ± 8.03) and the intervention groups (54.90 ± 9.51) (P = 0.313). However, a significant difference was observed between the control (50.90 ± 5.71) and the intervention groups (59.80 ± 5.27) regarding mean scores of self-efficacy at the end of the study (P < 0.001). Conclusions: Implementing the self-management program plus regular follow-up increased the perception of self-efficacy in patients with MS. Similar self-management programs are recommended to be integrated in the regular caring of patients with MS. PMID:25741519

    Background Slow progress has been made in achieving the Millennium Development Goals 4 and 5 in Ghana. Ensuring continuum of care (at least four antenatal visits; skilled birth attendance; postnatal care within 48 hours, at two weeks, and six weeks) for mother and newborn is crucial in helping Ghana achieve these goals and beyond. This study examined the levels and factors associated with continuum of care (CoC) completion among Ghanaian women aged 15–49. Methods A retrospective cross-sectional survey was conducted among women who experienced live births between January 2011 and April 2013 in three regions of Ghana. In a two-stage random sampling method, 1,500 women with infants were selected and interviewed about maternal and newborn service usage in line with CoC. Multiple logistic regression models were used to assess factors associated with CoC completion. Results Only 8.0% had CoC completion; the greatest gap and contributor to the low CoC was detected between delivery and postnatal care within 48 hours postpartum. About 95% of women had a minimum of four antenatal visits and postnatal care at six weeks postpartum. A total of 75% had skilled assisted delivery and 25% received postnatal care within 48 hours. Factors associated with CoC completion at 95% CI were geographical location (OR = 0.35, CI 0.13–0.39), marital status (OR = 0.45; CI 0.22–0.95), education (OR = 2.71; CI 1.11–6.57), transportation (OR = 1.97; CI 1.07–3.62), and beliefs about childhood illnesses (OR = 0.34; CI0.21–0.61). Conclusion The continuum of care completion rate is low in the study site. Efforts should focus on increasing postnatal care within 48 hours and overcoming the known obstacles to increasing the continuum of care completion rate. PMID:26650388

    Upon recognition of pathogen virulence effectors, plant nucleotide-binding leucine-rich repeat (NLR) proteins induce defense responses including localized host cell death. In an effort to understand the molecular mechanisms leading to this response, we examined the Arabidopsis thaliana NLR protein RECOGNITION OF PERONOSPORA PARASITICA1 (RPP1), which recognizes the Hyaloperonospora arabidopsidis effector ARABIDOPSIS THALIANA RECOGNIZED1 (ATR1). Expression of the N-terminus of RPP1, including the Toll/interleukin-1 receptor (TIR) domain (“N-TIR”), elicited an effector-independent cell death response, and we used allelic variation in TIR domain sequences to define the key residues that contribute to this phenotype. Further biochemical characterization indicated that cell death induction was correlated with N-TIR domain self-association. In addition, we demonstrated that the nucleotide-binding (NB)-ARC1 region of RPP1 self-associates and plays a critical role in cell death activation, likely by facilitating TIR:TIR interactions. Structural homology modeling of the NB subdomain allowed us to identify a putative oligomerization interface that was shown to influence NB-ARC1 self-association. Significantly, full-length RPP1 exhibited effector-dependent oligomerization and, although mutations at the NB-ARC1 oligomerization interface eliminated cell death induction, RPP1 self-association was unaffected, suggesting that additional regions contribute to oligomerization. Indeed, the leucine-rich repeat domain of RPP1 also self-associates, indicating that multiple interaction interfaces exist within activated RPP1 oligomers. Finally, we observed numerous intramolecular interactions that likely function to negatively regulate RPP1, and present a model describing the transition to an active NLR protein. PMID:27427964

    Slow progress has been made in achieving the Millennium Development Goals 4 and 5 in Ghana. Ensuring continuum of care (at least four antenatal visits; skilled birth attendance; postnatal care within 48 hours, at two weeks, and six weeks) for mother and newborn is crucial in helping Ghana achieve these goals and beyond. This study examined the levels and factors associated with continuum of care (CoC) completion among Ghanaian women aged 15-49. A retrospective cross-sectional survey was conducted among women who experienced live births between January 2011 and April 2013 in three regions of Ghana. In a two-stage random sampling method, 1,500 women with infants were selected and interviewed about maternal and newborn service usage in line with CoC. Multiple logistic regression models were used to assess factors associated with CoC completion. Only 8.0% had CoC completion; the greatest gap and contributor to the low CoC was detected between delivery and postnatal care within 48 hours postpartum. About 95% of women had a minimum of four antenatal visits and postnatal care at six weeks postpartum. A total of 75% had skilled assisted delivery and 25% received postnatal care within 48 hours. Factors associated with CoC completion at 95% CI were geographical location (OR = 0.35, CI 0.13-0.39), marital status (OR = 0.45; CI 0.22-0.95), education (OR = 2.71; CI 1.11-6.57), transportation (OR = 1.97; CI 1.07-3.62), and beliefs about childhood illnesses (OR = 0.34; CI0.21-0.61). The continuum of care completion rate is low in the study site. Efforts should focus on increasing postnatal care within 48 hours and overcoming the known obstacles to increasing the continuum of care completion rate.

  15. Artifacts and essentialism

    Psychological essentialism is an intuitive folk belief positing that certain categories have a non-obvious inner “essence” that gives rise to observable features. Although this belief most commonly characterizes natural kind categories, I argue that psychological essentialism can also be extended in important ways to artifact concepts. Specifically, concepts of individual artifacts include the non-obvious feature of object history, which is evident when making judgments regarding authenticity and ownership. Classic examples include famous works of art (e.g., the Mona Lisa is authentic because of its provenance), but ordinary artifacts likewise receive value from their history (e.g., a worn and tattered blanket may have special value if it was one's childhood possession). Moreover, in some cases, object history may be thought to have causal effects on individual artifacts, much as an animal essence has causal effects. I review empirical support for these claims and consider the implications for both artifact concepts and essentialism. This perspective suggests that artifact concepts cannot be contained in a theoretical framework that focuses exclusively on similarity or even function. Furthermore, although there are significant differences between essentialism of natural kinds and essentialism of artifact individuals, the commonalities suggest that psychological essentialism may not derive from folk biology but instead may reflect more domain-general perspectives on the world.

    Using the Transtheoretical Model of behavioral change, this study evaluates the relationship between sleep quality and the motivation and maintenance processes of healthy behavior change. The current study is an analysis of data collected in 2008 from an online health risk assessment (HRA) survey completed by participants of the Kansas State employee wellness program (N=13,322). Using multinomial logistic regression, associations between self-reported sleep quality and stages of change (i.e. precontemplation, contemplation, preparation, action, maintenance) in five health behaviors (stress management, weight management, physical activities, alcohol use, and smoking) were analyzed. Adjusted for covariates, poor sleep quality was associated with an increased likelihood of contemplation, preparation, and in some cases action stage when engaging in the health behavior change process, but generally a lower likelihood of maintenance of the healthy behavior. The present study demonstrated that poor sleep quality was associated with an elevated likelihood of contemplating or initiating behavior change, but a decreased likelihood of maintaining healthy behavior change. It is important to include sleep improvement as one of the lifestyle management interventions offered in EWP to comprehensively reduce health risks and promote the health of a large employee population.

    Introduction Finding ways to provide better and less expensive health care for people with multiple chronic conditions or disability is a pressing concern. The purpose of this systematic review was to evaluate different approaches for caring for this high-need and high-cost population. Methods We searched Medline for articles published from May 31, 2008, through June 10, 2014, for relevant studies. Articles were considered eligible for this review if they met the following criteria: included people with multiple chronic conditions (behavioral or mental health) or disabilities (2 or more); addressed 1 or more of clinical outcomes, health care use and spending, or patient satisfaction; and compared results from an intervention group with a comparison group or baseline measurements. We extracted information on program characteristics, participant characteristics, and significant (positive and negative) clinical findings, patient satisfaction, and health care use outcomes. For each outcome, the number of significant and positive results was tabulated. Results Twenty-seven studies were included across 5 models of care. Of the 3 studies reporting patient satisfaction outcomes, 2 reported significant improvements; both were randomized controlled trials (RCTs). Of the 14 studies reporting clinical outcomes, 12 reported improvements (8 were RCTs). Of the 13 studies reporting health care use and spending outcomes, 12 reported significant improvements (2 were RCTs). Two models of care — care and case management and disease management — reported improvements in all 3 outcomes. For care and case management models, most improvements were related to health care use. For the disease management models, most improvements were related to clinical outcomes. Conclusions Care and case management as well as disease management may be promising models of care for people with multiple chronic conditions or disabilities. More research and consistent methods are needed to understand the
