Systematic reviews: Separating fact from fiction.
Haddaway, Neal R; Bilotta, Gary S
2016-01-01
The volume of scientific literature continues to expand and decision-makers are faced with increasingly unmanageable volumes of evidence to assess. Systematic reviews (SRs) are powerful tools that aim to provide comprehensive, transparent, reproducible and updateable summaries of evidence. SR methods were developed, and have been employed, in healthcare for more than two decades, and they are now widely used across a broad range of topics, including environmental management and social interventions in crime and justice, education, international development, and social welfare. Despite these successes and the increasing acceptance of SR methods as a 'gold standard' in evidence-informed policy and practice, misconceptions still remain regarding their applicability. The aim of this article is to separate fact from fiction, addressing twelve common misconceptions that can influence the decision as to whether a SR is the most appropriate method for evidence synthesis for a given topic. Through examples, we illustrate the flexibility of SR methods and demonstrate their suitability for addressing issues on environmental health and chemical risk assessment.

[Play therapy for a child with separation anxiety disorder].
Wu, Y Y; Chiu, Y N; Soong, W T
1995-06-01
Separation anxiety disorder is characterized by severe and exceeding anxiety and fear when a child is facing separation with attachment objects. More over, it affected the child in language, emotional and social interest and development. These children usually brought to physician's attention due to refusal to go to school, social withdraw or multiple somatic complaints with attachment behavior wanted to be nearby or closed to the attachment objects. A child's early attachment relationship and previous separation experience play a major role in the formation of separation anxiety disorder. This report presents a psychoanalytically-oriented play therapy for a 2-year-8-month-old boy in 17 months period total of 54 sessions. According to the main themes in each session the process can be divided into 4 stages, namely establishing therapeutic relationship, expressing repressed emotions, management of transference, attachment and conflict in therapy, and self growth and termination. The formulation of this case and management were discussed.

PURPOSE: To gain experience in measuring quality of life (QOL) using the FACT-L in patients (pt) with non small cell lung cancer (NSCLC) treated with an altered fractionation regimen, HART, in a Phase II, multiinstitutional ECOG trial. MATERIALS AND METHODS: Version 2 of FACT-L, with 43 questions in 6 subscale categories (8 physical well-being, 8 social/family well-being, 3 relationship with doctor, 6 emotional well-being, 8 functional well-being, 10 lung cancer symptoms), available in English, Spanish and French, was administered by data managers and filled out by pts, independent of physician presence or input. The HART trial enrolled 30 pts, and FACT-L was administered at baseline (tp 1), treatment completion (tp 2) and 4 weeks following therapy (tp 3). (35(43)) FACT-L items were designed to yield a total QOL score with higher values reflective of better QOL; in addition, a FACT-L trial outcome index (TOI) was computed (TOI = physical score + functional score + lung cancer related score), and is considered the most relevant clinical QOL measure. RESULTS: The FACT-L completion rates were: tp 1 - (30(30)) (100%), tp 2 - (29(30)) (97%) and tp 3 - (24(30)) (80%); the mean scores at various time points are summarized in the table below and indicate that FACT-L is responsive to changes over time. The differences in subscales and total scores can be used as a measure of change in QOL resulting from treatment; statistically significant change was noted from baseline to tp 2 for physical, emotional and functional well-being; and from baseline to tp 3 for emotional well-being. The change in TOI score was also evaluated as a function of response and toxicity grade, and no clear association emerged. When assessed as a function of survival (at the time of this analysis, (5(30)) pt were alive, with median survival of 56 weeks), the degradation in QOL was most severe for pt who died early; the mean change in TOI from baseline to tp 3 for pt dying in the first 25 weeks, 25

Immune-modulating therapy in acute pancreatitis: Fact or fiction
Akinosoglou, Karolina; Gogos, Charalambos
2014-01-01
Acute pancreatitis (AP) is one of the most common diseases of the gastrointestinal tract, bearing significant morbidity and mortality worldwide. Current treatment of AP remains unspecific and supportive and is mainly targeted to aggressively prevent systemic complications and organ failure by intensive care. As acute pancreatitis shares an indistinguishable profile of inflammation with sepsis, therapeutic approaches have turned towards modulating the systemic inflammatory response. Targets, among others, have included pro- and anti-inflammatory modulators, cytokines, chemokines, immune cells, adhesive molecules and platelets. Even though, initial results in experimental models have been encouraging, clinical implementation of immune-regulating therapies in acute pancreatitis has had a slow progress. Main reasons include difficulty in clinical translation of experimental data, poor understanding of inflammatory response time-course, flaws in experimental designs, need for multimodal approaches and commercial drawbacks. Whether immune-modulation in acute pancreatitis remains a fact or just fiction remains to be seen in the future. PMID:25386069

2007-04-01
Full Text Available Abstract Background Although the Functional Assessment of Cancer Therapy – General questionnaire (FACT-G has been validated few studies have explored the factor structure of the instrument, in particular using non-sample dependent measurement techniques, such as Rasch Models. Furthermore, few studies have explored the relationship between item fit to the Rasch Model and clinical utility. The aim of this study was to investigate the dimensionality and measurement properties of the FACT-G with Rasch Models and Factor analysis. Methods A factor analysis and Rasch analysis (Partial Credit Model was carried out on the FACT-G completed by a heterogeneous sample of cancer patients (n = 465. For the Rasch analysis item fit (infit mean squares ≥ 1.30, dimensionality and item invariance were assessed. The impact of removing misfitting items on the clinical utility of the subscales and FACT-G total scale was also assessed. Results The factor analysis demonstrated a four factor structure of the FACT-G which broadly corresponded to the four subscales of the instrument. Internal consistency for these four scales was very good (Cronbach's alpha 0.72 – 0.85. The Rasch analysis demonstrated that each of the subscales and the FACT-G total scale had misfitting items (infit means square ≥ 1.30. All these scales with the exception of the Social & Family Well-being Scale (SFWB were unidimensional. When misfitting items were removed, the effect sizes and the clinical utility of the instrument were maintained for the subscales and the total FACT-G scores. Conclusion The results of the traditional factor analysis and Rasch analysis of the FACT-G broadly agreed. Caution should be exercised when utilising the Social & Family Well-being scale and further work is required to determine whether this scale is best represented by two factors. Additionally, removing misfitting items from scales should be performed alongside an assessment of the impact on clinical utility.

Science and evidence: separating fact from fiction.
Hess, Dean R
2013-10-01
Evidence-based medicine (EBM) is the integration of individual clinical expertise with the best available research evidence from systematic research and the patient's values and expectations. A hierarchy of evidence can be used to assess the strength upon which clinical decisions are made. The efficient approach to finding the best evidence is to identify systematic reviews or evidence-based clinical practice guidelines. Respiratory therapies that evidence supports include noninvasive ventilation for appropriately selected patients, lung-protective ventilation, and ventilator discontinuation protocols. Evidence does not support use of weaning parameters, albuterol for ARDS, and high frequency oscillatory ventilation for adults. Therapy with equivocal evidence includes airway clearance, selection of an aerosol delivery device, and PEEP for ARDS. Although all tenets of EBM are not universally accepted, the principles of EBM nonetheless provide a valuable approach to respiratory care practice.

Rapid cell separation with minimal manipulation for autologous cell therapies
Smith, Alban J.; O'Rorke, Richard D.; Kale, Akshay; Rimsa, Roberts; Tomlinson, Matthew J.; Kirkham, Jennifer; Davies, A. Giles; Wälti, Christoph; Wood, Christopher D.
2017-02-01
The ability to isolate specific, viable cell populations from mixed ensembles with minimal manipulation and within intra-operative time would provide significant advantages for autologous, cell-based therapies in regenerative medicine. Current cell-enrichment technologies are either slow, lack specificity and/or require labelling. Thus a rapid, label-free separation technology that does not affect cell functionality, viability or phenotype is highly desirable. Here, we demonstrate separation of viable from non-viable human stromal cells using remote dielectrophoresis, in which an electric field is coupled into a microfluidic channel using shear-horizontal surface acoustic waves, producing an array of virtual electrodes within the channel. This allows high-throughput dielectrophoretic cell separation in high conductivity, physiological-like fluids, overcoming the limitations of conventional dielectrophoresis. We demonstrate viable/non-viable separation efficacy of >98% in pre-purified mesenchymal stromal cells, extracted from human dental pulp, with no adverse effects on cell viability, or on their subsequent osteogenic capabilities.

Impairment of cognitive function, a common complaint in patients receiving chemotherapy, is usually measured through neuropsychological tests. Patient self-evaluation of cognitive difficulties is an important complement to those tests. The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) is a self-report questionnaire with potential to be used in standard clinical practice as a tool for evaluating patient's cognitive function before, during, and after chemotherapy. The purpose of our study was to conduct linguistic validation of the French version of the FACT-Cog. Both qualitative and quantitative methods were used in this study. After undergoing a rigorous translation methodology, the French FACT-Cog version was pretested in France with 35 cancer patients undergoing chemotherapy treatment. Interviews were conducted with all patients to ascertain their understanding of each item. The validation of the final version was conducted among 63 cancer patients, and sociodemographic information was collected as well as brief measure of cognitive function and depression score. Patient comments obtained through the cognitive debriefing interviews indicated that patients understand the French FACT-Cog items as they are intended and that the measure is culturally appropriate. Internal consistency reliability of the subscales, evaluated using Cronbach's coefficient alpha, was high for all four subscales: Perceived Cognitive Impairments = 0.93, Impact On QOL = 0.85, Comments From Others = 0.70, and Perceived Cognitive Abilities = 0.89. All item-total correlations for each subscale were greater than 0.20, and most were greater than 0.50. Results from this study effectively demonstrate that the French FACT-Cog is a reliable instrument for the self-reporting of cognitive abilities in patients undergoing chemotherapy.

Production and separation of terbium-149 and terbium-152 for targeted cancer therapy
International Nuclear Information System (INIS)
Sarkar, S.; Leigh, J.
1997-01-01
This work reports the production and separation of useful quantities of 149 , 152 Tb from natural neodymium ( nat Nd) and 141 Pr for in vitro studies by bombarding the targets with 12 C projectiles. The physical, chemical and nuclear properties of radionuclides determine their efficacy in therapy and diagnosis. Tb-149 is an alpha-emitter with a half-life of 4.1h and 152 Tb is a positron emitter with a half-life of 17.5 h. Both of the isotopes have suitable gamma emission with good branching ratio suggesting their application to diagnosis apart from therapy. Alpha-emitters are effective in controlling cancer because of their short range and high Relative Biological Effectiveness. Long-lived positron emitters are effective in studying physiological function in positron emission tomography other than therapy. The aim of this work is to optimise the production and carrier free separation of terbium. Because of the presence of other stable isotopes in nat Nd, a number of other lanthanides are produced by secondary reactions during the production of terbium. In order to remove the secondary products, α-hydroxyisobutyric acid of pH 5 was used as eluent. satisfactory separation of terbium was achieved and demonstrate that useful quantities of 144,152 Tb can be produced by Tandem accelerator from 141 Pr and nat Nd targets

This study aimed to test the reliability, psychometric, and clinical validity of the use of the Functional Assessment of Cancer Therapy--Brain (FACT-Br) in patients with brain metastases. Patients with brain metastases were interviewed using the FACT-Br (including the FACT-general) 1 week prior to treatment. All patients completed a follow-up assessment 1 month post-treatment. Patients with a good performance status and receiving stereotactic radiosurgery completed an additional 1 week follow-up assessment after the initial baseline interview to assess test-retest reliability. Forty patients had complete 1 month follow-up data. Ten of these patients also completed the 1 week follow-up assessment from baseline. The median Karnofsky performance status of patients was 80 and the median age was 64 years. All subscales of the FACT-Br were found to be conceptually related (except for two correlations) using the following subscales: physical well-being (PWB), social/family well-being (SWB), emotional well-being (EWB), functional well-being (FWB), FACT-G total score, brain cancer subscale (BrC), and the FACT-Br total score. All FACT-Br scores demonstrated excellent reliability, except for the SWB scale which revealed good reliability. The FACT-Br scores showed no significant change in the quality of life (QoL) of patients from baseline to 1 month follow-up. The use of the combined FACT-G and FACT-Br Subscale to assess QoL specifically in patients with brain metastases has successfully undergone psychometric validation. Future clinical trials should use the FACT-G and FACT-Br Subscale to assess QoL in this patient population.

In an in vitro study, fixed-combination fortified vancomycin and amikacin ophthalmic solutions (VA solution) had the same potency and stable physical properties as the separate components. In this retrospective clinical study, we evaluated the efficacy of the topical VA solution in the treatment of bacterial corneal ulcer and comparison with separate topical fortified vancomycin and amikacin. Separate topical fortified eye drops was used prior to January 2004 and switched to the VA solution afterwards in the treatment of bacterial corneal ulcer. The medical records of 223 patients diagnosed with bacterial corneal ulcers between January 2002 and December 2005 were reviewed retrospectively. There were 122 patients in the VA group and 101 in the separate group. Cure was defined as complete healing of the ulcer accompanied by a nonprogressive stromal infiltrate on two consecutive visits. No significant difference was found between the VA and separate therapy group. The mean treatment duration was 15.4 days in the VA group and 16.1 days in the separate therapy group. The average hospital stay was 5.4 days (VA) and 7.2 days (separate antibiotics). Stromal infiltration regressed significantly without further expansion in both groups. All corneal ulcers completely re-epithelialized without complications related to drugs. VA solution provided similar efficacy to the conventional separate therapy in the treatment of bacterial corneal ulcers; however, it is more convenient and tolerable, promotes patient's compliance, avoids the washout effect, and reduces nurse utilization. Hence, VA solution is a good alternative to separate therapy.

Pew research polls report 62 percent of U.S. adults get news on social media (Gottfried and Shearer, 2016). In a December poll, 64 percent of U.S. adults said that “made-up news” has caused a “great deal of confusion” about the facts of current events (Barthel et al., 2016). Fabricated stories spread in social media, ranging from deliberate propaganda to hoaxes and satire, contributes to this confusion in addition to having serious effects on global stability. In this work we build predictive models to classify 130 thousand news tweets as suspicious or verified, and predict four subtypes of suspicious news – satire, hoaxes, clickbait and propaganda. We demonstrate that neural network models trained on tweet content and social network interactions outperform lexical models. Unlike previous work on deception detection, we find that adding syntax and grammar features to our models decreases performance. Incorporating linguistic features, including bias and subjectivity, improves classification results, however social interaction features are most informative for finer-grained separation between our four types of suspicious news posts.

To investigate the influence of music therapy on the reduction of fatigue in women with breast or gynecological malignant neoplasia during radiotherapy, since it is one of the most frequent side effects of this type of treatment, and may interfere with self-esteem, social activities, and quality of life. Randomized controlled trial (control group [CG] and music therapy group [MTG]) to assess fatigue, quality of life, and symptoms of depression in women undergoing radiotherapy using the Functional Assessment of Cancer Therapy: Fatigue (FACT-F) version 4, Functional Assessment of Cancer Therapy-General (FACT-G) version 4, and Beck Depression Inventory in 3 separate times, namely, during the first week of radiotherapy, on the week of the intermediary phase, and during the last week of radiotherapy. Individual 30- to 40-minute sessions of music therapy with the presence of a trained music therapist were offered to participants. In this study, 164 women were randomized and 116 (63 CG and 53 MTG) were included in the analyses, with mean age of 52.90 years (CG) and 51.85 years (MTG). Participants in the MTG had an average of 10 music therapy sessions, totaling 509 sessions throughout the study. FACT-F results were significant regarding Trial Outcome Index ( P = .011), FACT-G ( P = .005), and FACT-F ( P = .001) for the MTG compared with the CG. Individual music therapy sessions may be effective to reduce fatigue related to cancer and symptoms of depression, as well as to improve quality of life for women with breast or gynecological cancer undergoing radiotherapy. Further well-designed research studies are needed to adequately determine the effects of music therapy on fatigue.

Individualized targeted therapy for glioblastoma: fact or fiction?
Weller, Michael; Stupp, Roger; Hegi, Monika; Wick, Wolfgang
2012-01-01
This review will address the current state of individualized cancer therapy for glioblastoma. Glioblastomas are highly malignant primary brain tumors presumably originating from neuroglial progenitor cells. Median survival is less than 1 year. Recent developments in the morphologic, clinical, and molecular classification of glioblastoma were reviewed, and their impact on clinical decision making was analyzed. Glioblastomas can be classified by morphology, clinical characteristics, complex molecular signatures, single biomarkers, or imaging parameters. Some of these characteristics, including age and Karnofsky Performance Scale score, provide important prognostic information. In contrast, few markers help to choose between various treatment options. Promoter methylation of the O-methylguanine methyltransferase gene seems to predict benefit from alkylating agent chemotherapy. Hence, it is used as an entry criterion for alkylator-free experimental combination therapy with radiotherapy. Screening for a specific type of epidermal growth factor receptor mutation is currently being explored as a biomarker for selecting patients for vaccination. Positron emission tomography for the detection of ανβ3/5 integrins could be used to select patients for treatment with anti-integrin antiangiogenic approaches. Despite extensive efforts at defining biological markers as a basis for selecting therapies, most treatment decisions for glioblastoma patients are still based on age and performance status. However, several ongoing clinical trials may enrich the repertoire of criteria for clinical decision making in the very near future. The concept of individualized or personalized targeted cancer therapy has gained significant attention throughout oncology. Yet, data in support of such an approach to glioblastoma, the most malignant subtype of glioma, are limited, and personalized medicine plays a minor role in current clinical neuro-oncology practice. In essence, this concept proposes

Food irradiation is at a political crossroad. In one direction, it is moving forward supported by overwhelming scientific evidence of its safety and benefits to economy and health. In the opposite direction, it threatens to be derailed by misleading claims about its safety and usefulness. Whether people will ultimately benefit from the use of irradiation to help fight serious food problems, or whether they will allow the technology to go to waste, will be determined by how successful people are in separating the facts from the fiction of food irradiation

Current research in molecular biology and genetics has dramatically advanced the understanding of the cellular events involved in homeostasis, disease, injury, and healing processes of the tissues of the musculoskeletal system. Recently, genetic predispositions to diseases have been described which offer novel means to address musculoskeletal disorders. Growth factors and cytokines have been identified as key elements in both the injured and healing states. Gene therapy offers an elegant solution to the delivery of therapeutic proteins to the site of disease or injury.

OBJECTIVE: The aim of this single-blind study was to investigate the perception of pain caused by orthodontic elastomeric separators with and without a single LLLT application (6J. METHODS: The sample comprised 79 individuals aged between 13 and 34 years old at orthodontic treatment onset. Elastomeric separators were placed in first maxillary molars at mesial and distal surfaces and kept in place for three days. The volunteers scored pain intensity on a visual analogue scale (VAS after 6 and 12 hours, and after the first, second and third days. One third of patients received laser applications, whereas another third received placebo applications and the remaining ones were controls. Applications were performed in a split-mouth design. Thus, three groups (laser, placebo and control were assessed. RESULTS: No differences were found among groups considering pain perception in all periods observed. CONCLUSION: The use of a single-dose of LLLT did not cause significant reduction in orthodontic pain perception. Overall pain perception due to orthodontic separator placement varied widely and was usually mild.

Full Text Available Abstract Background Amyotrophic lateral sclerosis (ALS is a fatal progressive neurodegenerative disorder affecting motor neurons in the spinal cord, brainstem and motor cortex, leading to muscle weakness. Muscle weakness may result in the avoidance of physical activity, which exacerbates disuse weakness and cardiovascular deconditioning. The impact of the grave prognosis may result in depressive symptoms and hopelessness. Since there is no cure for ALS, optimal treatment is based on symptom management and preservation of quality of life (QoL, provided in a multidisciplinary setting. Two distinctly different therapeutic interventions may be effective to improve or preserve daily functioning and QoL at the highest achievable level: aerobic exercise therapy (AET to maintain or enhance functional capacity and cognitive behavioural therapy (CBT to improve coping style and cognitions in patients with ALS. However, evidence to support either approach is still insufficient, and the underlying mechanisms of the approaches remain poorly understood. The primary aim of the FACTS-2-ALS trial is to study the effects of AET and CBT, in addition to usual care, compared to usual care alone, on functioning and QoL in patients with ALS.

Nebulized therapy. SEPAR year.
Olveira, Casilda; Muñoz, Ana; Domenech, Adolfo
2014-12-01
Inhaled drugs are deposited directly in the respiratory tract. They therefore achieve higher concentrations with faster onset of action and fewer side effects than when used systemically. Nebulized drugs are mainly recommended for patients that require high doses of bronchodilators, when they need to inhale drugs that only exist in this form (antibiotics or dornase alfa) or when they are unable to use other inhalation devices. Technological development in recent years has led to new devices that optimize pulmonary deposits and reduce the time needed for treatment. In this review we focus solely on drugs currently used, or under investigation, for nebulization in adult patients; basically bronchodilators, inhaled steroids, antibiotics, antifungals, mucolytics and others such as anticoagulants, prostanoids and lidocaine.

2014-01-01
Full Text Available The main goal of therapy for Parkinson's disease (PD is to correct dopamine deficiency in the nigrostriatal system. Levodopa preparations and dopamine receptor agonists (DRAs that are prescribed with regards to patient age and disease severity are mainly used now. Notwithstanding the fact that levodopa preparations are the gold standard of therapy, their long-term use gives rise to complications as motor fluctuations and drug-induced dyskinesias. The currently available DRAs are the drugs of choice for the therapy of early-stage PD as they are as effective as levodopa preparations. In extensive-stage PD, DRAs are used to enhance the therapy and correction of developed motor fluctuations and dyskinesias. Pramipexole is one of the most commonly used representatives of non-ergoline DRAs. The paper analyzes the efficacy of the medication used as both monotherapy and part of combined therapy, its effect on tremor and depression in PD. A novel extended-release formulation of pramipexole is considered separately. Both immediate- and extended-release pramipexole formulations contain the same active ingredient and have the same dopamine-receptor interaction profile, but differ in the tablet release rate of the active ingredient. The advantages of the novel formulation are its more steady-state plasma concentration and 24-hour action, which ensures continuous dopaminergic stimulation ofpostsynaptic receptors to prevent and treat already developed motor complications. The once-daily extended-release formulation of the drug makes its treatment regimen easier and patient compliance higher.

Full Text Available Adoptive cell therapy (ACT of autologous tumor infiltrating lymphocytes (TIL is an effective immunotherapy for patients with solid tumors, yielding objective response rates of around 40% in refractory patients with metastatic melanoma. Most clinical centers utilize bulk, randomly isolated TIL from the tumor tissue for ex vivo expansion and infusion. Only a minor fraction of the administered T cells recognizes tumor antigens, such as shared and mutation-derived neoantigens, and consequently eliminates the tumor. Thus, there are many ongoing effects to identify and select tumor-specific TIL for therapy; however, those approaches are very costly and require months, which is unreasonable for most metastatic patients. CD137 (4-1BB has been identified as a co-stimulatory marker, which is induced upon the specific interaction of T cells with their target cell. Therefore, CD137 can be a useful biomarker and an important tool for the selection of tumor-reactive T cells. Here, we developed and validated a simple and time efficient method for the selection of CD137-expressing T cells for therapy based on magnetic bead separation. CD137 selection was performed with clinical grade compliant reagents, and TIL were expanded in a large-scale manner to meet cell numbers required for the patient setting in a GMP facility. For the first time, the methodology was designed to comply with both clinical needs and limitations, and its feasibility was assessed. CD137-selected TIL demonstrated significantly increased antitumor reactivity and were enriched for T cells recognizing neoantigens as well as shared tumor antigens. CD137-based selection enabled the enrichment of tumor-reactive T cells without the necessity of knowing the epitope specificity or the antigen type. The direct implementation of the CD137 separation method to the cell production of TIL may provide a simple way to improve the clinical efficiency of TIL ACT.

To examine the responsiveness of Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Short Form-12 Health Survey version 2 (SF-12 v2) in prostate cancer patients because there is a lack of evidence to support their responsiveness in this patient population. One hundred sixty-eight subjects with prostate cancer were surveyed at baseline and at 6 months using the SF-12 v2 and FACT-P version 4. Internal responsiveness was assessed using paired t test and generalized estimating equation. External responsiveness was evaluated using receiver operating characteristic curve analysis. The internal responsiveness of the FACT-P and SF-12 v2 to detect positive change was satisfactory. The FACT-P and SF-12 v2 could not detect negative change. The FACT-P and the SF-12 v2 performed the best in distinguishing between improved general health and worsened general health. The FACT-P performed better in distinguishing between unchanged general health and worsened general health. The SF-12 v2 performed better in distinguishing between unchanged general health and improved general health. Positive change detected by these measures should be interpreted with caution as they might be too responsive to detect "noise," which is not clinically significant. The ability of the FACT-P and the SF-12 v2 to detect negative change was disappointing. The internal and external responsiveness of the social well-being of the FACT-P cannot be supported, suggesting that it is not suitable to longitudinally monitor the social component of HRQOL in prostate cancer patients. The study suggested that generic and disease-specific measures should be used together to complement each other.

Stem cells for amyotrophic lateral sclerosis modeling and therapy: myth or fact?
Coatti, G C; Beccari, M S; Olávio, T R; Mitne-Neto, M; Okamoto, O K; Zatz, M
2015-03-01
Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease whose pathophysiology is poorly understood. Aiming to better understand the cause of motor neuron death, the use of experimental cell-based models increased significantly over the past years. In this scenario, much knowledge has been generated from the study of motor neurons derived from embryonic stem cells and induced pluripotent stem cells. These methods, however, have advantages and disadvantages, which must be balanced on experimental design. Preclinical studies provide valuable information, making it possible to combine diverse methods to build an expanded knowledge of ALS pathophysiology. In addition to using stem cells as experimental models for understanding disease mechanism, these cells had been quoted for therapy in ALS. Despite ethical issues involved in its use, cell therapy with neural stem cells stands out. A phase I clinical trial was recently completed and a phase II is on its way, attesting the method's safety. In another approach, mesenchymal stromal cells capable of releasing neuroregulatory and anti-inflammatory factors have also been listed as candidates for cell therapy for ALS, and have been admitted as safe in a phase I trial. Despite recent advances, application of stem cells as an actual therapy for ALS patients is still in debate. Here, we discuss how stem cells have been useful in modeling ALS and address critical topics concerning their therapeutic use, such as administration protocols, injection site, cell type to be administered, type of transplantation (autologous vs. allogeneic) among other issues with particular implications for ALS therapy. © 2015 International Society for Advancement of Cytometry.

David F Yao
2016-01-01
Full Text Available While we may be comfortable with an allopathic approach to male infertility, we are also responsible for knowledge about lifestyle modifications and holistic, complementary, and alternative therapies that are used by many of our patients. This paper provides an evidence-based review separating fact from fiction for several of these therapies. There is sufficient literature to support weight reduction by diet and exercise, smoking cessation, and alcohol moderation. Supplements that have demonstrated positive effects on male fertility on small randomized controlled trial (RCT include aescin, coenzyme Q 10 , glutathione, Korean red ginseng, L-carnitine, nigella sativa, omega-3, selenium, a combination of zinc and folate, and the Menevit antioxidant. There is no support for the use of Vitamin C, Vitamin E, or saffron. The data for Chinese herbal medications, acupuncture, mind-body practice, scrotal cooling, and faith-based healing are sparse or inconclusive.

Previous work suggests that the Dutch variant of assertive community treatment (ACT), known as Function ACT (FACT), may be effective in increasing symptomatic remission rates when replacing a system of hospital-based care and separate community-based facilities. FACT guidelines propose a different pattern of psychiatric service consumption compared to traditional services, which should result in different costing parameters than care as usual (CAU). South-Limburg FACT patients, identified through the local psychiatric case register, were matched with patients from a non-FACT control region in the North of the Netherlands (NN). Matching was accomplished using propensity scoring including, among others, total and outpatient care consumption. Assessment, as an important ingredient of FACT, was the point of departure of the present analysis. FACT patients, compared to CAU, had five more outpatient contacts after the index date. Cost-effectiveness was difficult to assess. Implementation of FACT results in measurable changes in mental health care use.

Full Text Available Abstract Background In facioscapulohumeral dystrophy (FSHD muscle function is impaired and declines over time. Currently there is no effective treatment available to slow down this decline. We have previously reported that loss of muscle strength contributes to chronic fatigue through a decreased level of physical activity, while fatigue and physical inactivity both determine loss of societal participation. To decrease chronic fatigue, two distinctly different therapeutic approaches can be proposed: aerobic exercise training (AET to improve physical capacity and cognitive behavioural therapy (CBT to stimulate an active life-style yet avoiding excessive physical strain. The primary aim of the FACTS-2-FSHD (acronym for Fitness And Cognitive behavioural TherapieS/for Fatigue and ACTivitieS in FSHD trial is to study the effect of AET and CBT on the reduction of chronic fatigue as assessed with the Checklist Individual Strength subscale fatigue (CIS-fatigue in patients with FSHD. Additionally, possible working mechanisms and the effects on various secondary outcome measures at all levels of the International Classification of Functioning, Disability and Health (ICF are evaluated. Methods/Design A multi-centre, assessor-blinded, randomized controlled trial is conducted. A sample of 75 FSHD patients with severe chronic fatigue (CIS-fatigue ≥ 35 will be recruited and randomized to one of three groups: (1 AET + usual care, (2 CBT + usual care or (3 usual care alone, which consists of no therapy at all or occasional (conventional physical therapy. After an intervention period of 16 weeks and a follow-up of 3 months, the third (control group will as yet be randomized to either AET or CBT (approximately 7 months after inclusion. Outcomes will be assessed at baseline, immediately post intervention and at 3 and 6 months follow up.

Separation of uranium isotopes
International Nuclear Information System (INIS)
Ehrfeld, W.; Ehrfeld, U.
1977-01-01
In the nuclear fuel cycle, uranium enrichment is not a principal problem of technological feasibility. Several processes exist for producing LWR fuel and the enrichment method can be selected in consideration of economical, environmental, and political aspects. To date, the gaseous diffusion process constitutes the major part of enrichment capacity. This process has been well demonstrated for over 30 years and, as a matter of fact, no major technological and economical progress is to be expected in the future. Because of their comparatively high development potential, the centrifuge and the separation nozzle method may become increasingly favorable in economics. The development of the centrifuge process which is superior by its low specific energy consumption aims at technological improvements. In the separation nozzle process which offers the advantage of a comparatively simple technology a further reduction of the specific energy consumption is to be expected because of the thermodynamically favorable separation mechanism of this process. Laser isotope separation methods are still on the laboratory scale, although large financial funds have been spent. (orig.) [de

The Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) scale, a leukemia-specific instrument for determining the health-related quality of life (HRQOL) in patients with leukemia, had been developed and validated, but there have been no reports on the development of a simplified Chinese version of this scale. This is a new exploration to analyze the reliability of the HRQOL measurement using multivariate generalizability theory (MGT). This study aimed to develop a Chinese version of the FACT-Leu scale and evaluate its reliability using MGT to provide evidence to support the revision and improvement of this scale. The Chinese version of the FACT-Leu scale was developed by four steps: forward translation, backward translation, cultural adaptation and pilot-testing. The HRQOL was measured for eligible inpatients with leukemia using this scale to provide data. A single-facet multivariate Generalizability Study (G-study) design was demonstrated to estimate the variance-covariance components and then several Decision Studies (D-studies) with varying numbers of items were analyzed to obtain reliability coefficients and to understand how much the measurement reliability could be vary as the number of items in MGT changes. One-hundred and one eligible inpatients diagnosed with leukemia were recruited and completed the HRQOL measurement at the time of admission to the hospital. In the G-study, the variation component of the patient-item interaction was largest while the variation component of the item was the smallest for the four of five domains, except for the leukemia-specific (LEUS) domain. In the D-study, at the level of domain, the generalizability coefficients (G) and the indexes of dependability (Ф) for four of the five domains were approximately equal to or greater than 0.80 except for the Emotional Well-being (EWB) domain (>0.70 but number of items were obtained: one is a 37-item version while the other is a 45-item version.

Short Remarks on the Principle of Separation of Powers
Directory of Open Access Journals (Sweden)
Ionela Despa
2012-05-01
Full Text Available The principle of separation of powers, as a basic principle of a real democratic political system,concerns that state activities, powers are separated by the fact that they take place separately, distinct fromone another, each with its specific, but in the social polical reality it can be seen that there are linksbetween public authorities in terms of organizational and functional, namely cooperation and mutualdeterminations. In terms of organization, the link is given by the fact that some state bodies involved in theformation of other, and the functional aspect concerns the connection of collaborations: theconstitutionality of laws passed by Parliament is controlled by the Constitutional Court or Governmentactivity can be examined by Parliament. The modern form of the principle of separation of powers requiresautonomous public authorities, sharing their incumbent functions, establishment of means of cooperationand mutual control, all in the ambience of a genuine and real autonomy. So a state cannot work unless thelaw adopted by thelegislature is applied to urge the executive and the judiciary by the executive contestcarries out its decisions. This cooperation should be accompanied by a power control, equipped with legaland institutional means that will not neutralize eachother.

Full Text Available Background: Emotion-focused cognitive behavioral therapy (ECBT is a new form of CBT with emotion regulation components. This form of treatment is suggested to be employed to improve dysregulation of anxiety and other kind of emotions in anxious children. This study observed and compared the effectiveness of CBT and ECBT on anxiety symptoms; sadness and anger management; and cognitive emotion regulation strategies in children with separation anxiety disorder (SAD. Materials and Methods: This study is a randomized clinical trial. Subjects were 30 children from 9 to 13-years-old (15 girls and 15 boys with diagnosis of SAD, being randomly assigned to CBT, ECBT, and control groups (five girls and five boys in each group. Subject children in CBT group participated in 10-h weekly sessions within Coping Cat manual; whereas, subject children in ECBT group contributed in 12-h weekly sessions within ECBT. The control group received no treatment.

Sound arithmetic: auditory cues in the rehabilitation of impaired fact retrieval.
Domahs, Frank; Zamarian, Laura; Delazer, Margarete
2008-04-01
The present single case study describes the rehabilitation of an acquired impairment of multiplication fact retrieval. In addition to a conventional drill approach, one set of problems was preceded by auditory cues while the other half was not. After extensive repetition, non-specific improvements could be observed for all trained problems (e.g., 3 * 7) as well as for their non-trained complementary problems (e.g., 7 * 3). Beyond this general improvement, specific therapy effects were found for problems trained with auditory cues. These specific effects were attributed to an involvement of implicit memory systems and/or attentional processes during training. Thus, the present results demonstrate that cues in the training of arithmetic facts do not have to be visual to be effective.

FACT. New image parameters based on the watershed-algorithm
Energy Technology Data Exchange (ETDEWEB)
Linhoff, Lena; Bruegge, Kai Arno; Buss, Jens [TU Dortmund (Germany). Experimentelle Physik 5b; Collaboration: FACT-Collaboration
2016-07-01
FACT, the First G-APD Cherenkov Telescope, is the first imaging atmospheric Cherenkov telescope that is using Geiger-mode avalanche photodiodes (G-APDs) as photo sensors. The raw data produced by this telescope are processed in an analysis chain, which leads to a classification of the primary particle that induce a shower and to an estimation of its energy. One important step in this analysis chain is the parameter extraction from shower images. By the application of a watershed algorithm to the camera image, new parameters are computed. Perceiving the brightness of a pixel as height, a set of pixels can be seen as 'landscape' with hills and valleys. A watershed algorithm groups all pixels to a cluster that belongs to the same hill. From the emerging segmented image, one can find new parameters for later analysis steps, e.g. number of clusters, their shape and containing photon charge. For FACT data, the FellWalker algorithm was chosen from the class of watershed algorithms, because it was designed to work on discrete distributions, in this case the pixels of a camera image. The FellWalker algorithm is implemented in FACT-tools, which provides the low level analysis framework for FACT. This talk will focus on the computation of new, FellWalker based, image parameters, which can be used for the gamma-hadron separation. Additionally, their distributions concerning real and Monte Carlo Data are compared.

The antileukemic mechanisms of 6-mercaptopurine (6MP) and methotrexate (MTX) maintenance therapy are poorly understood, but the benefits of several years of myelosuppressive maintenance therapy for acute lymphoblastic leukemia are well proven. Currently, there is no international consensus on drug dosing. Because of significant interindividual and intraindividual variations in drug disposition and pharmacodynamics, vigorous dose adjustments are needed to obtain a target degree of myelosuppression. As the normal white blood cell counts vary by patients’ ages and ethnicity, and also within age groups, identical white blood cell levels for 2 patients may not reflect the same treatment intensity. Measurements of intracellular levels of cytotoxic metabolites of 6MP and MTX can identify nonadherent patients, but therapeutic target levels remains to be established. A rise in serum aminotransferase levels during maintenance therapy is common and often related to high levels of methylated 6MP metabolites. However, except for episodes of hypoglycemia, serious liver dysfunction is rare, the risk of permanent liver damage is low, and aminotransferase levels usually normalize within a few weeks after discontinuation of therapy. 6MP and MTX dose increments should lead to either leukopenia or a rise in aminotransferases, and if neither is experienced, poor treatment adherence should be considered. The many genetic polymorphisms that determine 6MP and MTX disposition, efficacy, and toxicity have precluded implementation of pharmacogenomics into treatment, the sole exception being dramatic 6MP dose reductions in patients who are homozygous deficient for thiopurine methyltransferase, the enzyme that methylates 6MP and several of its metabolites. In conclusion, maintenance therapy is as important as the more intensive and toxic earlier treatment phases, and often more challenging. Ongoing research address the applicability of drug metabolite measurements for dose adjustments

Disaster mythology and fact: Hurricane Katrina and social attachment.
Jacob, Binu; Mawson, Anthony R; Payton, Marinelle; Guignard, John C
2008-01-01
Misconceptions about disasters and their social and health consequences remain prevalent despite considerable research evidence to the contrary. Eight such myths and their factual counterparts were reviewed in a classic report on the public health impact of disasters by Claude de Ville de Goyet entitled, The Role of WHO in Disaster Management: Relief, Rehabilitation, and Reconstruction (Geneva, World Health Organization, 1991), and two additional myths and facts were added by Pan American Health Organization. In this article, we reconsider these myths and facts in relation to Hurricane Katrina, with particular emphasis on psychosocial needs and behaviors, based on data gleaned from scientific sources as well as printed and electronic media reports. The review suggests that preparedness plans for disasters involving forced mass evacuation and resettlement should place a high priority on keeping families together--and even entire neighborhoods, where possible--so as to preserve the familiar and thereby minimize the adverse effects of separation and major dislocation on mental and physical health.

The tumors of the brain claim for a separate position in scientific medicine regarding biology, morphology, features of clinical manifestation, diagnostics and therapy. During the past years due to rapid progress in medical biotechnics the situation of the neuroclinician in front of brain tumors has been dramatically changed. The prerequisites for early and accurate diagnosis as well as for successful treatment also of malignant neoplasms have increased and remarkably improved. At the same time the information necessary for an appropriate pragmatic use of the available cognitive methods and therapeutic means increased along the same scale. These facts necessitate the preparation of publications in which the state of the art is presented in possible completeness, systematic order and proper dis-posability for rational management and therapeutic strategies. The primary aim of the present book is to serve these purposes. With 8 chapters, two of them are indexed for INIS, the collective of competent authors deal on the biology, pathology and immunology of malignant brain tumors of adults and of children including relevant basic and recent data of experimental research; further on the available methods of therapy: neurosurgery, radiology and chemotherapy, the fundamental principals of their efficacy and the differing models of single respective combined application, in comprehensive critical form. 111 figs

2016-07-01
Imaging Atmospheric Cherenkov Telescopes (IACTs) like FACT produce a continuous flow of data during measurements. Analyzing the data in near real time is essential for monitoring sources. One major task of a monitoring system is to detect changes in the gamma-ray flux of a source, and to alert other experiments if some predefined limit is reached. In order to calculate the flux of an observed source, it is necessary to run an entire data analysis process including calibration, image cleaning, parameterization, signal-background separation and flux estimation. Software built on top of a data streaming framework has been implemented for FACT and generalized to work with the data acquisition framework of the Cherenkov Telescope Array (CTA). We present how the streams-framework is used to apply supervised machine learning models to an online data stream from the telescope.

Of these, 25 patients with low-risk prostate cancer received C-ion RT alone, whereas the remaining 125 patients with a high-risk tumor also received androgen deprivation therapy. Quality of life was assessed using the self-administered Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire in all patients three times. In addition, University of California-Los Angeles Prostate Cancer Index (UCLA-PCI) was conducted in the low-risk patients. Results: The FACT-General (FACT-G) and FACT-P scores at 12 months after treatment averaged over all 150 patients showed no significant change compared with those before C-ion RT. In FACT-P subscales, emotional well-being increased significantly just after and 12 months after treatment. In contrast, physical well-being (PWB) and social/family well-being (S/FWB) decreased significantly at 12 months, whereas the prostate cancer subscale (PCS) decreased significantly just after treatment. Average scores for FACT-G, FACT-P, PWB, S/FWB, and PCS for the 125 patients receiving hormone therapy showed substantial detrimental changes at 12 months. In contrast, those of the 25 low-risk patients who had no hormone therapy showed no significant change. Similarly no significant change in the average of the UCLA-PCI scores in the low-risk patients was seen at 12 months. Conclusions: Average QOL parameters reported by patients with localized prostate cancer treated with C-ion RT, in the absence of hormone therapy, showed no significant decrease 12 months after C-ion RT

Introduction: Cognitive therapy is a method of psychotherapy used to treat many psychological and psychiatric disorders and is based on cognitive model of emotional disorders. Throughout the therapy, it is important for the clients to be trained in their problems and to perceive the fact which is one of the fundamental actions of cognitive behavioral therapy, that the emotional state interacts not only with in the thoughts, but also physical functions and environment. . Besides employing cogn...

John Searle on Institutional Facts

Here we argue that the essence of institutional facts is status functions. Humans recognize these functions which contain a set of deontic powers through collective intentionality. Therefore, institutional facts are ontologically subjective and epistemologically objective. Nevertheless, objectivity of institutional facts totally depends on language which itself is a fundamental institution for other institutions.

Full Text Available Focuses on the way Melville Herkovits used facts and facticity in his scientific work on creolization, and how these facts related to the theories in his work. Author relates this to the idea of fact as a stand-alone datum, or "fetish", independent of any theory for its existence. He describes how Herkovits in his work presented classifications of intensity of African retentions in different parts of the Americas, as well as of cultural elements, which Herkovits meant to be heuristic, yet, the author argues, seemed to precede the data. Further, the author discusses criticisms on this "economic anthropology". In addition, he sketches how the data as fetish, and related induction, developed out of the scientific revolution in Europe, separating arguments from facts, but also out of colonial ventures and the history of the slave trade in West Africa, making it a part of the study of creolization, of African slavery and the African diaspora. He points out, and applaudes, that Herkovits' theoretical stance changed from a strict empiricism to an awareness of the place of argument, or social convention, in the making of the facts themselves.

Play Therapy is based upon the fact that play is the child's natural medium of self-expression. It is an opportunity that is given to the child to "play out" his/her feelings and problems just as, in certain types of adult therapy, an individual "talks out" his difficulties. Children use play to express feelings and thoughts.…

Spin-charge separation in ultra-cold quantum gases
Recati, A.; Fedichev, P. O.; Zwerger, W.; Zoller, P.
2002-01-01
We investigate the physical properties of quasi-1D quantum gases of fermion atoms confined in harmonic traps. Using the fact that for a homogeneous gas, the low energy properties are exactly described by a Luttinger model, we analyze the nature and manifestations of the spin-charge separation. Finally we discuss the necessary physical conditions and experimental limitations confronting possible experimental implementations.

Full Text Available The rise of multi-drug resistance has decreased the effectiveness of antibiotics, which has led to increased mortality rates associated with symptomatic bacteremia, or bacterial sepsis. To combat decreasing antibiotic effectiveness, extracorporeal bacterial separation approaches have been proposed to capture and separate bacteria from blood. However, bacteremia is dynamic and involves host-pathogen interactions across various anatomical sites. We developed a mathematical model that quantitatively describes the kinetics of pathogenesis and progression of symptomatic bacteremia under various conditions, including bacterial separation therapy, to better understand disease mechanisms and quantitatively assess the biological impact of bacterial separation therapy. Model validity was tested against experimental data from published studies. This is the first multi-compartment model of symptomatic bacteremia in mammals that includes extracorporeal bacterial separation and antibiotic treatment, separately and in combination. The addition of an extracorporeal bacterial separation circuit reduced the predicted time of total bacteria clearance from the blood of an immunocompromised rodent by 49%, compared to antibiotic treatment alone. Implementation of bacterial separation therapy resulted in predicted multi-drug resistant bacterial clearance from the blood of a human in 97% less time than antibiotic treatment alone. The model also proposes a quantitative correlation between time-dependent bacterial load among tissues and bacteremia severity, analogous to the well-known 'area under the curve' for characterization of drug efficacy. The engineering-based mathematical model developed may be useful for informing the design of extracorporeal bacterial separation devices. This work enables the quantitative identification of the characteristics required of an extracorporeal bacteria separation device to provide biological benefit. These devices will potentially

ARTiiFACT: a tool for heart rate artifact processing and heart rate variability analysis.
Kaufmann, Tobias; Sütterlin, Stefan; Schulz, Stefan M; Vögele, Claus
2011-12-01
The importance of appropriate handling of artifacts in interbeat interval (IBI) data must not be underestimated. Even a single artifact may cause unreliable heart rate variability (HRV) results. Thus, a robust artifact detection algorithm and the option for manual intervention by the researcher form key components for confident HRV analysis. Here, we present ARTiiFACT, a software tool for processing electrocardiogram and IBI data. Both automated and manual artifact detection and correction are available in a graphical user interface. In addition, ARTiiFACT includes time- and frequency-based HRV analyses and descriptive statistics, thus offering the basic tools for HRV analysis. Notably, all program steps can be executed separately and allow for data export, thus offering high flexibility and interoperability with a whole range of applications.

Full Text Available Abstract Background The objective of this study was to construct and validate a brief, clinically-relevant symptom index for advanced prostate cancer. Methods Questions were extracted from a commonly-used multi-dimensional cancer quality of life instrument with prostate-specific items, the Functional Assessment of Cancer Therapy-Prostate (FACT-P. Surveys of disease-related symptoms were presented to an international sample of 44 expert physicians. Each expert narrowed the list to no more than five of the most important symptoms or concerns to monitor when assessing the value of treatment for advanced prostate cancer. Symptoms/concerns endorsed at a frequency greater than chance probability (17% were retained for the symptom index and called the FACT Advanced Prostate Symptom Index-8 (FAPSI-8: pain (three items, fatigue, weight loss, urinary difficulties (two items, and concern about the condition becoming worse. The FAPSI-8 was validated using data from a clinical trial of 288 men being treated for hormone refractory prostate cancer. Results The FAPSI-8 showed good internal consistency (r = 0.67–0.80; association with existing FACT scales (e.g., FACT-P, Physical Well-being, Functional Well-being; r = 0.44–0.85, p Conclusions This project produced a reliable and valid list of the eight most important clinician-rated targets of drug therapy for advanced prostate cancer. These questions perform comparably to the longer derivative questionnaire. Examination of patient agreement with this priority list and the extent to which changes in these 8 targets are related to meaningful clinical benefit to the patient are important next steps for future research.

Facilitates chromatin transcription (FACT) is a chromatin remodeling complex with two subunits: SSRP1 and SPT16. Mechanisms controlling FACT levels are of interest, since the complex is not expressed in most differentiated cells, but is frequently upregulated in cancer, particularly in poorly differentiated, aggressive tumors. Moreover, inhibition of FACT expression or function in tumor cells interferes with their survival. Here we demonstrate that SSRP1 and SPT16 protein levels decline upon induction of cellular differentiation or senescence in vitro and that similar declines in protein levels for both SSRP1 and SPT16 occur upon RNAi-mediated knockdown of either SSRP1 or SPT16. The interdependence of SSRP1 and SPT16 protein levels was found to be due to their association with SSRP1 and SPT16 mRNAs, which stabilizes the proteins. In particular, presence of SSRP1 mRNA is critical for SPT16 protein stability. In addition, binding of SSRP1 and SPT16 mRNAs to the FACT complex increases the stability and efficiency of translation of the mRNAs. These data support a model in which the FACT complex is stable when SSRP1 mRNA is present, but quickly degrades when SSRP1 mRNA levels drop. In the absence of FACT complex, SSRP1 and SPT16 mRNAs are unstable and inefficiently translated, making reactivation of FACT function unlikely in normal cells. Thus, we have described a complex and unusual mode of regulation controlling cellular FACT levels that results in amplified and stringent control of FACT activity. The FACT dependence of tumor cells suggests that mechanisms controlling FACT levels could be targeted for anticancer therapy.

FACT. Bokeh alignment for Cherenkov telescopes
Energy Technology Data Exchange (ETDEWEB)
Mueller, Sebastian Achim [ETH Zurich (Switzerland); Buss, Jens [TU Dortmund (Germany)
2016-07-01
Imaging Atmospheric Cherenkov Telescopes (IACTs) need fast and large imaging optics to map the faint Cherenkov light emitted in cosmic ray air showers onto their image sensors. Segmented reflectors are inexpensive, lightweight and offer good image quality. However, alignment of the mirror facets remains a challenge. A good alignment is crucial in IACT observations to separate gamma rays from hadronic cosmic rays. We present a simple, yet extendable method, to align segmented reflectors using their Bokeh. Bokeh alignment does not need a star or good weather nights but can be done anytime, even during the day. Bokeh alignment optimizes the facet orientations by comparing the segmented reflector's Bokeh to a predefined template. The Bokeh is observed using the out of focus image of a nearby point like light source in a distance of about ten times the focal lengths. We introduce Bokeh alignment on segmented reflectors and present its use on the First Geiger-mode Avalanche Cherenkov Telescope (FACT) on Canary Island La Palma, as well as on the Cherenkov Telescope Array (CTA) Medium Size Telescope (MST) prototype in Berlin Adlershof.

The ethics of separating conjoined twins: two arguments against.
Kallberg, Luke
2018-02-01
I argue that the separation of conjoined twins in infancy or early childhood is unethical (rare exceptions aside). Cases may be divided into three types: both twins suffer from lethal abnormalities, only one twin has a lethal abnormality, or neither twin does. In the first kind of case, there is no reason to separate, since both twins will die regardless of treatment. In the third kind of case, I argue that separation at an early age is unethical because the twins are likely to achieve an irreplaceably good quality of life-the goods of conjoinment-that separation takes away. Evaluation of this possibility requires maturation past early childhood. Regarding the second type, I point out that with conceivable but unrecorded exceptions, these cases will consistently involve sacrifice separation. I present an argument that sacrifice separation is unethical, but in some cases a moral dilemma may exist in which separation and refraining from separation are both unethical. Perhaps in such cases a decision can be made on non-moral grounds; however, the possibility of such a decision serves not to mitigate but to underscore the fact that the separation is unethical. My conclusion, which applies to all three types of cases, is that it is unethical to separate conjoined twins before their developing personalities give some reliable indication as to whether they desire separation and whether they will achieve those goods of conjoinment.

Purpose Chemohormonal therapy with docetaxel and androgen deprivation therapy (ADT+D) for metastatic hormone-sensitive prostate cancer improves overall survival as compared with androgen deprivation therapy (ADT) alone. We compared the quality of life (QOL) between patients with metastatic hormone-sensitive prostate cancer who were treated with ADT+D and those who were treated with ADT alone. Methods Men were randomly assigned to ADT+ D (six cycles) or to ADT alone. QOL was assessed by Functional Assessment of Cancer Therapy-Prostate (FACT-P), FACT-Taxane, Functional Assessment of Chronic Illness Therapy-Fatigue, and the Brief Pain Inventory at baseline and at 3, 6, 9, and 12 months. The Wilcoxon signed rank test was used to examine changes over time. Mixed-effect models compared the QOL between arms at each time point. Results Seven hundred ninety men were randomly assigned (ADT+D [n = 397] and ADT[ n = 393]) and completed FACT-P (90% at baseline, 86% at 3 months, 83% at 6 months, 78% at 9 months, and 77% at 12 months). ADT+D patients reported a statistically significant decline in FACT-P at 3 months ( P < .001) but FACT-P did not differ significantly between baseline and 12 months ( P = .38). ADT+D FACT-P scores were significantly lower at 3 months ( P = .02) but significantly higher at 12 months ( P = .04) when compared with ADT FACT-P scores. Differences did not exceed the minimal clinically important difference at any time point. ADT+D patients reported significantly lower Functional Assessment of Chronic Illness Therapy-Fatigue scores at 3 months than did ADT patients ( P < .001). Over time, both arms reported significantly poorer FACT-Taxane scores ( P < .001) when compared with baseline. Brief Pain Inventory scores were similar between arms. Conclusion Although ADT+D was associated with statistically worse QOL at 3 months, QOL was better at 12 months for ADT+D patients than for ADT patients. Both arms reported a similar minimally changed QOL over time

A study was made of the separation properties of cellulose pressure columns operating at a slight over-pressure of around 1 atmosphere, with respect to the length of the column packing, the flow rate, and the load. The optimal separation stage heights of the columns are situated at H=0.16 mm. Since as a consequence of the favorable separation stage heights observed at column lengths of 3 to 7 cm, separation stage numbers of 200 to 400 are attained, and hence it is possible to attain separations within several minutes with flow rates of 1 ml/min. The choice of the mobile phase is made easier by the fact that paper chromatographic Rsub(f)-values can be transferred to the cellulose pressure column with the aid of a transfer function. (author)

Since its emergence in 2012, the genome editing technique known as CRISPR-Cas9 and its scientific use have rapidly expanded globally within a very short period of time. The technique consists of using an RNA guide molecule to bind to complementary DNA sequences, which simultaneously recruits the endonuclease Cas9 to introduce double-stranded breaks in the target DNA. The resulting double-stranded break is then repaired, allowing modification or removal of specific DNA bases. The technique has gained momentum in the laboratory because it is cheap, quick, and easy to use. Moreover, it is also being applied in vivo to generate more complex animal model systems. Such use of genome editing has proven to be highly effective and warrants a potential therapy for both genetic and non-genetic diseases. Although genome editing has the potential to be a transformative therapy for patients it is still in its infancy. Consequently, the legal and ethical frameworks are yet to be fully discussed and will be an increasingly important topic as the technology moves towards more contentious issues such as modification of the germline. Here, we review a number of scientific and ethical issues which may potentially influence the development of both the technology and its use in the clinical setting.

Size-uniform gold nanorods (Au-NRs) are used in biosensing, bioimaging, photothermal therapy, drug and gene delivery, and controlled release. Monodisperse Au-NRs are usually obtained by separation steps following their synthesis, and centrifugation is widely used because of the ease of operation, high recovery, and the good availability of equipment. So far, the effect of viscosity on the separation of Au-NRs has not been investigated. We have developed a method for separation of monodisperse Au-NRs that is based on centrifugation in a viscosity gradient. Monodisperse Au-NRs obtained from gold nanoparticles were obtained by centrifugation in viscosity gradient adjusted with poly(2-ethyl-2-oxazoline). Au-NRs in sizes ranging from 25.6 to 26.1 nm in effective radius can be separated 5500 g within 5 min, which appears to be the fastest method for separation of Au-NRs. (author)

Although androgen deprivation therapy is widely used to treat prostate cancer, its effects on cognitive function are unclear. To our knowledge no prior report has examined the impact of androgen deprivation therapy on self-reported cognitive function. Three groups of men 50 years old or older who were matched on age and education were enrolled in the study, including 81 with prostate cancer starting on continuous androgen deprivation therapy, 84 controls with prostate cancer not receiving androgen deprivation therapy and 85 healthy controls. Two scales from the FACT-Cog (Functional Assessment of Cancer Therapy-Cognitive subscale) version 3 were used to assess self-reported cognitive function. Changes in cognitive scores with time were analyzed by 2 approaches, including 1) multivariable regression and 2) calculation of the proportion of subjects per group with a decrease of 1 SD or more. Multivariable regression was applied to assess predictors of a decline in self-reported cognitive function. We also examined relationships between the FACT-Cog and a neuropsychological battery of 15 tests. Mean participant age was 69 years (range 50 to 87). The mean educational level was 15 years (range 8 to 24). FACT-Cog scores were similar at baseline across the cohorts. Neither analytical approach revealed that androgen deprivation therapy was associated with changes in self-reported cognitive function on either FACT-Cog scale. Mood and fatigue correlated with changes in self-reported cognitive function. The relationship between self-reported and objective cognitive measures was weak (maximum Spearman correlation coefficient 0.14) and only 2 of 30 correlations were statistically significant. A total of 12 months of androgen deprivation therapy were not associated with self-reported cognitive function changes in older men with nonmetastatic prostate cancer.

90 Y of high specific activity and very high radionuclidic purity (>99.998%) is essential for targeted therapy. Since the current methods used for the preparation of 90 Y from 90 Sr are not adaptable for use in a central/hospital radiopharmacy, a simple 90 Sr- 90 Y generator system based on electrochemical separation technique was developed. Methods: Two-cycle electrolysis procedure was developed for separation of 90 Y from 90 Sr in nitrate solution. The first electrolysis was performed for 90 min in 90 Sr(NO 3 ) 2 feed solution at pH 2-3 at a potential of -2.5V with 100-200 mA current using platinum electrodes. The second electrolysis was performed for 45 min in 3 mM HNO 3 at a potential of -2.5V with 100 mA current. In this step, the cathode from the first electrolysis containing 90 Y was used as anode along with a fresh circular platinum electrode as cathode. The 90 Y deposited on the circular cathode after the second electrolysis was dissolved in acetate buffer to obtain 90 Y acetate, suitable for radiolabeling. Results: >96% recovery of 90 Y could be achieved in each cycle, with an overall decay corrected yield of >90%. The recovered 90 Y had high radionuclidic purity with barely 30.2±15.2 kBq (817±411 nCi) of 90 Sr per 37 GBq (1 Ci) of 90 Y (0.817±0.411 ppm). Consistent and repeated separation could be demonstrated using up to 1.85 GBq (50 mCi) of 90 Sr. The generator was named 'Kamadhenu,' the eternally milk-yielding Indian mythological cow. Conclusions: A technique suitable for adaptation at central radiopharmacies for obtaining therapeutic quantities of pure 90 Y has been developed

Full Text Available The Drug Facts Label is designed to guide consumers in comparing nonprescription drugs. Undergraduates studied and recalled drug facts for three analgesic or non-analgesic labels using Drug Facts Label headings as retrieval cues. They then studied and recalled drug facts from an aspirin label. Aspirin recall was greater when the prior labels were analgesics, but prior-label intrusion errors were also greater. These two effects were associated with the number of prior drug labels on which facilitating and interfering drug facts appeared. Using the Drug Facts Label schema to read drug labels can both enhance and degrade the recall of nonprescription drug facts.

The benefits of exercise gained by older adults during physical therapy are often not maintained once the program is over. This lack of sustained benefits is thought to be partially the result of poor adherence to the prescribed home exercise program to be continued once therapy is completed. Most of what is known about older adults' adherence to physical therapy and home exercise comes from research seeking to identify and understand predictors of adherence, rather than trying to enhance adherence explicitly. The purpose of this study was to test a theoretically grounded approach to promoting adherence to home exercise programs in older adults. Sixty older adults (M age = 69.3 (6.87) years) in a program of physical therapy received 1 of 2 print messages and magnets promoting adherence to home exercise. The content of the messages was informed by the goal-specific tenets of socioemotional selectivity theory-one message described the emotional and meaningful benefits of home exercise, such as time with loved ones and independence, and one message described facts and information about physiological benefits, such as balance and strength. Adherence to home exercise was measured 2 weeks after participants were discharged from physical therapy by calculating the percentage of the prescribed exercises participants reported completing at home. An analysis of covariance indicated that there was no statistically significant difference in adherence rates between participants receiving either message. However, a 2×2 analysis of covariance did reveal a significant interaction between the type of message participants received and the time at which they received that message. Post hoc analyses separately examined the rates of adherence in participants who received the intervention message with time remaining in their therapy program and participants who received the intervention message on the day of discharge. In the subset of participants who received their intervention

Dissociative identity disorder (DID) is a complex, posttraumatic, developmental disorder for which we now, after four decades of research, have an authoritative research base, but a number of misconceptualizations and myths about the disorder remain, compromising both patient care and research. This article examines the empirical literature pertaining to recurrently expressed beliefs regarding DID: (1) belief that DID is a fad, (2) belief that DID is primarily diagnosed in North America by DID experts who overdiagnose the disorder, (3) belief that DID is rare, (4) belief that DID is an iatrogenic, rather than trauma-based, disorder, (5) belief that DID is the same entity as borderline personality disorder, and (6) belief that DID treatment is harmful to patients. The absence of research to substantiate these beliefs, as well as the existence of a body of research that refutes them, confirms their mythical status. Clinicians who accept these myths as facts are unlikely to carefully assess for dissociation. Accurate diagnoses are critical for appropriate treatment planning. If DID is not targeted in treatment, it does not appear to resolve. The myths we have highlighted may also impede research about DID. The cost of ignorance about DID is high not only for individual patients but for the whole support system in which they reside. Empirically derived knowledge about DID has replaced outdated myths. Vigorous dissemination of the knowledge base about this complex disorder is warranted.

Full Text Available Background: Breast cancer affects over one million women annually and is the most common global malignancy among women. Extensive improvements have taken place in the management of breast cancer in recent years and a higher percentage of women are cured from this disease. A proper assessment of the quality of life of women with breast cancer is an essential component in disease management. The Functional Assessment of Cancer Therapy- Breast Symptom Index has been commonly used and well-validated among English speaking populations as well as other populations. To date, no formal translation and evaluation of the Functional Assessment of Cancer Therapy-Breast System Index exists in Arabic. Therefore, this study intends to translate, adapt and face-validate the Functional Assessment of Cancer Therapy-Breast System Index into Arabic, specifically in the context of the Lebanese culture. Methods: We conducted forward and backward translation in Arabic, combined with face validity by clinicians. This was followed by pre-testing to ensure the instrument’s adequacy and cultural sensitivity conducted by the administration of face-to-face interviews with individual breast cancer patients (n=33 and two focus groups (4 women/group to evaluate the relevance and appropriateness of each item and words used in the questionnaire. Results: Study results reinforced the value of the Arabic translated version of the Functional Assessment of Cancer Therapy-Breast System Index in capturing the quality of life of women with breast cancer in Lebanon. Conclusion: The instrument was perceived to be adequate, appropriate for use, culturally sensitive, simple as well as exhaustive. Suggestions have been made to enrich the instruments’ ability to incorporate other quality of life dimensions not captured, as well to enhance the cultural specificity of the Functional Assessment of Cancer Therapy-Breast System Index, when administered among Lebanese women diagnosed with

Human mesenchymal stem cells can differentiate into multiple lineages for cell therapy and, therefore, have attracted considerable research interest recently. This study presents a new microfluidic device for bead and cell separation utilizing a combination of T-junction focusing and tilted louver-like structures. For the first time, a microfluidic device is used for continuous separation of amniotic stem cells from amniotic fluids. An experimental separation efficiency as high as 82.8% for amniotic fluid mesenchymal stem cells is achieved. Furthermore, a two-step separation process is performed to improve the separation efficiency to 97.1%. These results are based on characterization experiments that show that this microfluidic chip is capable of separating beads with diameters of 5, 10, 20, and 40 microm by adjusting the volume-flow-rate ratio between the flows in the main and side channels of the T-junction focusing structure. An optimal volume-flow-rate ratio of 0.5 can lead to high separation efficiencies of 87.8% and 85.7% for 5-microm and 10-microm beads, respectively, in a one-step separation process. The development of this microfluidic chip may be promising for future research into stem cells and for cell therapy.

Vibration-type particle separation device with piezoceramic vibrator
Ooe, Katsutoshi; Doi, Akihiro
2008-12-01
During hemanalysis, it is necessary to separate blood cells from whole blood. Many blood separation methods, for example, centrifugation and filtering, are in practical use. However, the use of these methods involves problems from the perspectives of processing speed and processing volume. We develop new types of blood separation devices that use piezo-ceramic vibrators. The first device uses a capillary. One end of the capillary is fixed to the device frame, and the other is fixed to a piezo-ceramic vibrator. The vibrator transmits bending waves to the capillary. This device can process only a small amount of solution; therefore, it is not suitable for hemanalysis. In order to solve this problem, we developed a second device; this device has a pair of thin glass plates with a small gap as a substitute for the capillary used in the first device. These devices are based on the fact that particles heavier than water move toward transverse velocity antinodes while those lighter than water move toward velocity nodes. In this report, we demonstrate the highspeed separation of silica microbeads and 50-vol% glycerol water by using these devices. The first device can separate the abovementioned solution within 3 min while the second can separate it within 1 min. Both devices are driven by a rectangular wave of 15 to 20 Vpp. Furthermore, it has been confirmed that red blood cells are separated from diluted whole blood using the first device within approximately 1 min. These devices have transparency, so they can compose as the analysis system with the chemical analyzer easily.

The use of alternative therapies in the Saskatchewan stroke rehabilitation population
Directory of Open Access Journals (Sweden)

2002-07-01
Full Text Available Abstract Background Many patients use alternative therapies. The purpose of this study was to determine the percentage of stroke rehabilitation patients in Saskatchewan using alternative therapies, whether patients found these therapies effective in alleviating stroke-related symptoms, how often those patients who used alternative therapies discuss this fact with their primary care doctor and the main reason why patients might not do so. Methods Telephone questionnaire surveys were conducted with 117 patients who had suffered a stroke and undergone inpatient or outpatient rehabilitation at Saskatoon City Hospital. Results The study revealed that 26.5% of 117 stroke rehabilitation patients visited alternative practitioners at least once or used some form of unconventional therapy. Only 16.1% of patients found that alternative therapy made them feel much better. Of those who used alternative therapy, 61.3% did not discuss this fact with their primary physician. Many of the respondents (47.3% who did not inform their physician stated that they did not see the necessity of talking about these treatments and 21.1% did not discuss the issue with their physician because they felt that he or she might disapprove of alternative therapies. Conclusion A relatively small percentage of stroke patients found alternative therapies beneficial. Doctors should be aware that a significant number of patients will try alternative treatment without discussion with their primary care physician or specialist. The current study suggests that after completing routine questioning, doctors should also ask their patients about their use of alternative therapies and, when appropriate, review issues of safety and efficacy.

Groundwater Flow Model of the General Separations Area Using PORFLOW
International Nuclear Information System (INIS)
FLACH, GREGORY
2004-01-01
The E Area PA (McDowell-Boyer et al. 2000) includes a steady-state simulation of groundwater flow in the General Separations Area as a prerequisite for saturated zone contaminant transport analyses. The groundwater flow simulations are based on the FACT code (Hamm and Aleman2000). The FACT-based GSA model was selected during preparation of the original PA to take advantage of an existing model developed for environmental restoration applications at the SRS (Flach and Harris 1997, 1999; Flach 1999). The existing GSA/FACT model was then slightly modified for PA use, as described in the PA document. FACT is a finite-element code utilizing deformed brick elements. Material properties are defined at element centers, and state variables such as hydraulic head are located at element vertices. The PORFLOW code (Analytic and Computational Research, Inc. 2000) was selected for performing saturated zone transport simulations of source zone radionuclides and their progeny. PORFLOW utilizes control volume discretization and the nodal point integration method, with all properties and state variables being defined at the center of an interior grid cell. The groundwater flow calculation includes translating the Darcy velocity field computed by FACT into a form compatible for input to PORFLOW. The FACT velocity field is defined at element vertices, whereas PORFLOW requires flux across cell faces. For the present PA, PORFLOW cell face flux is computed in a two-step process. An initial face flux is computed from FACT as an average of the normal components of Darcy velocity at the four corners. The derived flux field approximately conserves mass, but not rigorously. Thus, the flux field is subsequently perturbed to force rigorous mass conservation on a cell-by-cell basis. The undocumented process used is non-unique and can introduce significant artifacts into the final flux field

Experimental Study of Unsteady Flow Separation in a Laminar Boundary Layer
Bonacci, Andrew; Lang, Amy; Wahidi, Redha; Santos, Leonardo
2017-11-01
Flow separation, caused by an adverse pressure gradient, is a major problem in many applications. Reversing flow near the wall is the first sign of incipient separation and can bristle shark scales which may be linked to a passive, flow actuated separation control mechanism. An investigation of how this backflow forms and how it interacts with shark skin is of interest due to the fact that this could be used as a bioinspired means of initiating flow control. A water tunnel experiment aims to study unsteady separation with a focus on the reversing flow development near the wall within a flat plate laminar boundary layer (Re on order of 105) as an increasing adverse pressure gradient is induced by a rotating cylinder. Unsteady reversing flow development is documented using DPIV. Funding was provided by the National Science Foundation under the Research Experience for Undergraduates (REU) program (EEC 1659710) and the Army Research Office.

Development and validation of the functional assessment of cancer therapy-antiangiogenesis subscale.
Kaiser, Karen; Beaumont, Jennifer L; Webster, Kimberly; Yount, Susan E; Wagner, Lynne I; Kuzel, Timothy M; Cella, David
2015-05-01
The Functional Assessment of Cancer Therapy (FACT)-Antiangiogenesis (AntiA) Subscale was developed and validated to enhance treatment decision-making and side effect management for patients receiving anti-angiogenesis therapies. Side effects related to anti-angiogenesis therapies were identified from the literature, clinician input, and patient input. Fifty-nine possible patient expressions of side effects were generated. Patient and clinician ratings of the importance of these expressions led us to develop a 24-item questionnaire with clinical and research potential. To assess the scale's reliability and validity, 167 patients completed the AntiA Subscale, the Functional Assessment of Cancer Therapy-general (FACT-G), the FACT-Kidney Symptom Index (FKSI), the FACIT-Fatigue Subscale, the Global Rating of Change Scale (GRC), and the PROMIS Global Health Scale. Patient responses to the AntiA were analyzed for internal consistency, test-retest reliability, convergent and discriminant validity, and responsiveness to change in clinical status. All tested scales were found to have good internal consistency reliability (Cronbach's alpha 0.70-0.92). Test-retest reliability was also good (0.72-0.88) for total and subscale scores and lower for individual items. The total score, subscale scores, and all single items (except nosebleeds) significantly differentiated between groups defined by level of side effect bother. Evaluation of responsiveness to change in this study was not conclusive, suggesting an area for further research. The AntiA is a reliable and valid measure of side effects from anti-angiogenesis therapy. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Highlights: ► This paper provides a review of methods using ionic liquids as azeotrope breakers. ► Azeotrope breaking potential of ILs was compared to that of conventional solvents. ► The influence of ILs structure on the azeotrope breaking capacity was accomplished. ► Guidelines to select the most suitable ILs as azeotrope breakers were established. - Abstract: Efforts to make existing separation methods more efficient and eco-friendly may get a boost from the use of a relatively new class of compounds known as ionic liquids (ILs). The separation of azeotropic mixtures has conventionally been one of the most challenging tasks in industrial processes due to the fact that their separation by simple distillation is basically impossible. This paper provides a critical review of methods using ILs as azeotrope breakers. Three separation processes were addressed: liquid–liquid extraction, extractive distillation, and supported liquid membranes. We examine the azeotrope breaking potential of ILs and compare their performance to that of conventional solvents. A systematic analysis of the influence of the structure of ILs on their azeotrope breaking capacity contributes to the establishment of guidelines for selecting the most suitable ILs for the separation of specific azeotropic mixtures.

FACTS device control strategy using PMU
Directory of Open Access Journals (Sweden)
Mohd Tauseef Khan
2016-09-01
Full Text Available The laying and commissioning of new transmission line is very difficult due to socio-economic problems, like environmental clearances, right of way, etc. Therefore, there is an emphasis on better utilization of available transmission infrastructure. FACTS devices can provide reactive power compensation, transmission capability enhancement, and voltage and stability improvement. FACTS devices operate under the command of system operator who analyses its demand by the data acquired through traditional SCADA system, state estimation algorithms and PMUs. SCADA together with PMU give accurate information about the operational state of power system. This paper proposes a scheme to automate the FACTS devices in collaboration with PMUs in a more efficient way. Highly precised data from PMUs can be fed to intelligent controllers for effective analyzing and automating the FACTS device through control command. Thus, this combination can provide real time control of reactive power, together with enhancement of power handling capability and stability improvement.

The purpose of this study was to identify the influential factors responsible for clinical instrument separation of reused ProTaper Universal rotary instruments (Dentsply Maillefer, Ballaigues, Switzerland). Six thousand one hundred fifty-four root canals in 2,654 teeth were prepared using ProTaper Universal files in endodontic clinics. Separation incidence was determined based on the number of treated teeth or canals. Data were collected including the size of fractured instrument, the length and location of a broken segment within the root canal, and the curvature of canal. The chi-square test and independent samples t test were used to determine the statistical significance. The overall instrument separation incidences were 2.6% according to the number of teeth and 1.1% according to the canal number, respectively. Separation incidences according to the number of teeth or canals were significantly higher (P molars than those in premolars or anterior teeth. Because of its largest diameter, F3 file presented the highest separation incidence according to the number of teeth (1.0%) or canals (0.4%); 47.5% instrument separation of mandibular molars and 61.5% instrument separation of maxillary molars happened in the mesiobuccal canals. Moreover, 91.4% fragments were located in the apical third of root canals, and 54.2% instrument separation occurred in severely curved canals. There was a significant difference (P < .05) in the mean fracture length between shaping (2.42 ± 0.73 mm) and finishing files (3.32 ± 0.73 mm). Separation incidence according to the canal number is more reliable than that according to the number of teeth because of the variable canal number in different teeth. The tooth type, rotary file size, canal location, and anatomy were correlated with the instrument separation of reused ProTaper Universal files. Copyright © 2011 American Association of Endodontists.

However, it is not always possible to quantitate specifically such reactions in the face of multiple drug therapy, which may enhance radiation injury or reactivate prior radiation injury. Prior detailed reviews have provided important sources of information concerning radiation injury for this more general discussion. The information provided will assist both the clinician and the radiologist in the recognition of early and late complications of therapy in pediatric oncology

The link between recent or imminent separation and violence against female partners is discussed. Interviews were conducted among 87 divorced, separated and domestic violence survivors during 1985-88 to study violence perpetrated by men against their female intimate partners. Various bodies of literature are reviewed to establish the fact that separation heightens the risk of violence. The conceptual contributions of social learning and power and control theories are presented as they pertain to intimate violence against women. An expanded version of the power-and-control model is used to underscore the violence proneness of separations, especially when women initiate separations. To illustrate the expanded model, numerous Canadian examples are provided, drawn from interviews with divorced women, survivors of intimate violence, and news media reports. Finally, different strategies to break the cycle of violence are summarized.

FACT. Normalized and asynchronous mirror alignment for Cherenkov telescopes
Energy Technology Data Exchange (ETDEWEB)
Mueller, Sebastian Achim [ETH Zurich (Switzerland); Buss, Jens [TU Dortmund (Germany)
2016-07-01
Imaging Atmospheric Cherenkov Telescopes (IACTs) need fast and large imaging optics to map the faint Cherenkov light emitted in cosmic ray air showers onto their image sensors. Segmented reflectors are inexpensive, lightweight and offer good image quality. However, alignment of the mirror facets remains a challenge. A good alignment is crucial in IACT observations to separate gamma rays from hadronic cosmic rays. We present a star tracking alignment method which is not restricted to clear nights. It normalizes the mirror facet reflections to be independent of the reference star or the cloud coverage. It records asynchronously of the telescope drive which makes the method easy to integrate in existing telescopes. It can be combined with remote facet actuation, but it does not need one to work. Furthermore, it can reconstruct all individual mirror facet point spread functions. We present the method and alignment results on the First Geiger-mode Photo Diode Avalanche Cherenkov Telescope (FACT) on the Canary Island of La Palma, Spain.

Using Epigenetic Therapy to Overcome Chemotherapy Resistance.
Strauss, Julius; Figg, William D
2016-01-01
It has been known for decades that as cancer progresses, tumors develop genetic alterations, making them highly prone to developing resistance to therapies. Classically, it has been thought that these acquired genetic changes are fixed. This has led to the paradigm of moving from one cancer therapy to the next while avoiding past therapies. However, emerging data on epigenetic changes during tumor progression and use of epigenetic therapies have shown that epigenetic modifications leading to chemotherapy resistance have the potential to be reversible with epigenetic therapy. In fact, promising clinical data exist that treatment with epigenetic agents can diminish chemotherapy resistance in a number of tumor types including chronic myelogenous leukemia, colorectal, ovarian, lung and breast cancer. The potential for epigenetic-modifying drugs to allow for treatment of resistant disease is exciting and clinical trials have just begun to evaluate this area.

International Nuclear Information System (INIS)
Herrera-Herrera, Antonio V.; González-Curbelo, Miguel Ángel; Hernández-Borges, Javier; Rodríguez-Delgado, Miguel Ángel
2012-01-01
Highlights: ► The use of CNTs in Separation Science in the period 2009–2011 is reviewed. ► CNTs as stationary phases in LC, CE and GC. ► CNTs as pseudostationary phases in EKC. ► CNTs as sorbents in SPE and SPME. ► Other uses of CNTs in separation science, as LDI substrates or in membranes. - Abstract: Due to the intensive and multidisciplinary research carried out during the last two decades on carbon nanotubes (CNTs), the scientific community understands nowadays much better the chemistry, structure and properties of these interesting materials. In fact, they have found their particular place in a wide number of application fields (nanotechnology, electronics, optics, medicine, etc.) among which Analytical Chemistry is becoming more and more important. The aim of this review is to provide an updated report of the most recent manuscripts (years 2009–2011) regarding the use of CNTs in Separation Science. In particular, the use of CNTs as solid-phase extraction and microextraction sorbents, as part of membranes as well as their use in chromatography and electrophoresis will be discussed and commented. Besides, although not as fully related to Separation Science as the previous techniques, the use of CNTs as laser desorption/ionization substrates has also been considered because of its importance in the field.

Separation and determination of 103Ru in samples of fission 99Mo
International Nuclear Information System (INIS)
Aghazarian, V.P.; Duran, Adrian P.; Mondino, Angel V.
2003-01-01
In Argentina 99 Mo is produced in the RA-3 reactor at the Ezeiza Atomic Center (CAE), by irradiation of miniplates of Al/U (90% 235 U) alloy. The 99 Mo separation is carried out at the Fission Radioisotopes Production Plant. Quality control is important to assure the quality of molybdenum that is produced in CAE. A new method to purify and on line quantify 103 Ru as an impurity present in 99 Mo samples was developed. This procedure is based in the RuO 4 volatilization and its dissolution in NaOH 6M. This is necessary due to the fact that 103 Ru cannot be detected in presence of high activities of 99 Mo without previous separation. This method allows a quantitative, specific, efficient, fast and reproducible separation of 103 Ru from 99 Mo. (author)

Pineal tumours are increasingly identified histologically since the introduction of the surgical microscope and microsurgical techniques. A major biological characteristic of germ-cell tumours is the fact that they produce tumour markers. Meaningful therapy planning is determined by the biological behaviour of the individual tumour entity which is strongly influenced by its intracranial localization. Important risk factors need to be identified and weighted according to previous treatment in order to arrive at an adequate therapy with improved curative prospects. Three risk areas can be defined for tumour extension. Therapy planning is also determined by the metastatic spread behaviour of germ-cell tumours. Within the two therapy studies for nontesticular germ-cell tumours MAKEI 83 and 86, a total of 180 germ-cell tumours, 24 of which were localized intercranially, were reported from 46 different clinics. All patients have a survival probability according to Kaplan and Meier of 67 ± 10% at an observation duration of 48 months. (orig./MG) [de

Heavy-ion cancer therapy with 12 C-beam has been carried out at HIMAC (Heavy Ion Medical Accelerator in Chiba) in NIRS (National Institute of Radiological Sciences) since 1994. One of the feasibility study in HIMAC is to use a positron emitter beam such as 11 C-beam for the cancer therapy. A nuclear reaction, 14 N (p,α) 11 C will be applied in the present study; it can be expected to obtain a considerably large number of 11 C-particles by utilizing the commonly used short-lives RI production techniques for PET (Positron Emission Tomography). The amount of 11 C gas is limited in this technique. The 11 CO 2 gas was produced from N 2 gas that is irradiated high-energy proton beam. Therefore, CO 2 gas separation from N 2 gas is very important. The gas-separation techniques with cryogenic system utilizing a liquid Ar were tested by dummy gas (N 2 + 12 CO 2 ). Details of the gas-separation techniques and measurement of CO 2 partial pressure are discussed. (author)

Full Text Available Background: Borderline Personality disorder is a disabling disease affecting 2% of general population. Various drugs have been suggested for treatment of borderline Personality disorder. If a drug could alleviate a wide range of symptoms, it would be more suitable. In these disorders drug addiction is very common. This fact makes the symptoms complicated and the treatment more difficult. This study is designed to evaluate the effect of Olanzapine and Sertraline in patients suffering from personality disorders who are on methadone maintenance therapy. Materials and Methods: This clinical trial study was carried out on 120 male and female cases chosen for methadone maintenance therapy through interview by a psychiatrist based on DSM-IV-TR diagnostic criteria for BPD. Afterwards they were randomly divided into two groups. These groups separately received Olanzapine (5-10 mg daily and Sertraline (50-100 mg daily therapy. The SCL-90 questionnaire was filled out by the participants before treatment and at the 4th, 8th and 12th weeks of the treatment. Results: According to this clinical trial, Olanzapine and Sertraline were effective in ameliorating symptoms of depression, anxiety and aggression, reducing sensitivity in interpersonal relationship and alleviating obsessive symptoms, pessimistic behaviors and somatization disorders in patients with personality disorders on methadone maintenance therapy. Conclusion: As results of this study stated that Olanzapine and Sertraline are definitely effective in alleviating symptoms of patients with personality disorder, prescribing theses drugs are highly recommended for these patients. .

Microparticle Separation by Cyclonic Separation
Karback, Keegan; Leith, Alexander
2017-11-01
The ability to separate particles based on their size has wide ranging applications from the industrial to the medical. Currently, cyclonic separators are primarily used in agriculture and manufacturing to syphon out contaminates or products from an air supply. This has led us to believe that cyclonic separation has more applications than the agricultural and industrial. Using the OpenFoam computational package, we were able to determine the flow parameters of a vortex in a cyclonic separator in order to segregate dust particles to a cutoff size of tens of nanometers. To test the model, we constructed an experiment to separate a test dust of various sized particles. We filled a chamber with Arizona test dust and utilized an acoustic suspension technique to segregate particles finer than a coarse cutoff size and introduce them into the cyclonic separation apparatus where they were further separated via a vortex following our computational model. The size of the particles separated from this experiment will be used to further refine our model.

Targeted Gene Therapy of Cancer: Second Amendment toward Holistic Therapy.
Barar, Jaleh; Omidi, Yadollah
2013-01-01
It seems solid tumors are developing smart organs with specialized cells creating specified bio-territory, the so called "tumor microenvironment (TME)", in which there is reciprocal crosstalk among cancer cells, immune system cells and stromal cells. TME as an intricate milieu also consists of cancer stem cells (CSCs) that can resist against chemotherapies. In solid tumors, metabolism and vascularization appears to be aberrant and tumor interstitial fluid (TIF) functions as physiologic barrier. Thus, chemotherapy, immunotherapy and gene therapy often fail to provide cogent clinical outcomes. It looms that it is the time to accept the fact that initiation of cancer could be generation of another form of life that involves a cluster of thousands of genes, while we have failed to observe all aspects of it. Hence, the current treatment modalities need to be re-visited to cover all key aspects of disease using combination therapy based on the condition of patients. Perhaps personalized cluster of genes need to be simultaneously targeted.

Canine separation anxiety: strategies for treatment and management
Directory of Open Access Journals (Sweden)
Sargisson RJ
2014-10-01
Full Text Available Rebecca J Sargisson School of Psychology, University of Waikato, Tauranga, New ZealandAbstract: Dogs with separation-related behavior problems engage in unwanted behavior such as destruction of property and excessive vocalization when left alone, causing distress for both the dog and the owner, and often leading to the dog being relinquished or euthanized. I review research on factors likely to predispose dogs to developing separation anxiety and on the treatments available. Although research is equivocal, dogs seem to develop separation-related behavior problems if they are male, sourced from shelters or found, and separated from the litter before they are 60 days old. Protective factors include ensuring a wide range of experiences outside the home and with other people between the ages of 5–10 months, stable household routines and absences from the dog, and the avoidance of punishment. The most successful treatment for canine separation-related problems may be behavior modification that focuses on systematic desensitization and counterconditioning, which can be supplemented with medication in the initial stages. Where individual therapy from an animal behavior expert is not possible, advice to dog owners should be clear, simple, and contain five or fewer instructions to improve adherence. Advice is given for people seeking to adopt a dog, for new dog owners, and for existing dog owners who wish to treat their dog’s separation anxiety.Keywords: systematic desensitization, counterconditioning, medication, separation anxiety

A Newtonian separable model which violates Bell's inequality
International Nuclear Information System (INIS)
Notarrigo, S.
1984-01-01
On the basis of the Mackey's axiomatization of quantum mechanics an argument is given which allows, in determinate circumstances, the violation of Bell's inequality also in a ''classical mechanics'' and a ''classical probability'' context. A classical model made out of two separate subsystems of coupled oscillators is studied by computer experiments to illustrate the point. In fact, the model violates Bell's inequality. The hypothesis is put forward that the principal reason for this violation is due to the special kind of ''detectors'' introduced in the model which gave a ''count'' every time a given dynamical variable of the mechanical system crosses an assigned threshold

Fake facts and alternative truths in medical research.
Hofmann, Bjørn
2018-01-27
Fake news and alternative facts have become commonplace in these so-called "post-factual times." What about medical research - are scientific facts fake as well? Many recent disclosures have fueled the claim that scientific facts are suspect and that science is in crisis. Scientists appear to engage in facting interests instead of revealing interesting facts. This can be observed in terms of what has been called polarised research, where some researchers continuously publish positive results while others publish negative results on the same issue - even when based on the same data. In order to identify and address this challenge, the objective of this study is to investigate how polarised research produce "polarised facts." Mammography screening for breast cancer is applied as an example. The main benefit with mammography screening is the reduced breast cancer mortality, while the main harm is overdiagnosis and subsequent overtreatment. Accordingly, the Overdiagnosis to Mortality Reduction Ratio (OMRR) is an estimate of the risk-benefit-ratio for mammography screening. As there are intense interests involved as well as strong opinions in debates on mammography screening, one could expect polarisation in published results on OMRR. A literature search identifies 8 studies publishing results for OMRR and reveals that OMRR varies 25-fold, from 0.4 to 10. Two experts in polarised research were asked to rank the attitudes of the corresponding authors to mammography screening of the identified publications. The results show a strong correlation between the OMRR and the authors' attitudes to screening (R = 0.9). Mammography screening for breast cancer appears as an exemplary field of strongly polarised research. This is but one example of how scientists' strong professional interests can polarise research. Instead of revealing interesting facts researchers may come to fact interests. In order to avoid this and sustain trust in science, researchers should disclose

Power system stability enhancement using facts controllers: a review
International Nuclear Information System (INIS)
Abido, M. A
2009-01-01
In recent years, power demand has increased substantially while the expansion of power generation and transmission has been severely limited due to limited resources and environmental restrictions. As a consequence, some transmission lines are heavily loaded and the system stability becomes a power transfer-limiting factor. Flexible AC transmission systems (FACTS) controllers have been mainly used for solving various power system steady state control problems. However, recent studies reveal that FACTS controllers could be employed to enhance power system stability in addition to their main function of power flow control. The literature shows an increasing interest in this subject for the last two decades, where the enhancement of system stability using FACTS controllers has been extensively investigated. This paper presents a comprehensive review on the research and developments in the power system stability enhancement using FACTS damping controllers. Several technical issues related to FACTS installations have been highlighted and performance comparison of different FACTS controllers has been discussed. In addition, some of the utility experience, real-world installations, and semiconductor technology development have been reviewed and summarized. Applications of FACTS to other power system studies have also been discussed. About two hundred twenty seven research publications have been classified and appended for a quick reference. (author)

We consider the dynamics towards the initial singularity of Bianchi type IX vacuum and orthogonal perfect fluid models with a linear equation of state. Surprisingly few facts are known about the 'Mixmaster' dynamics of these models, while at the same time most of the commonly held beliefs are rather vague. In this paper, we use Mixmaster facts as a base to build an infrastructure that makes it possible to sharpen the main Mixmaster beliefs. We formulate explicit conjectures concerning (i) the past asymptotic states of type IX solutions and (ii) the relevance of the Mixmaster/Kasner map for generic past asymptotic dynamics. The evidence for the conjectures is based on a study of the stochastic properties of this map in conjunction with dynamical systems techniques. We use a dynamical systems formulation, since this approach has so far been the only successful path to obtain theorems, but we also make comparisons with the 'metric' and Hamiltonian 'billiard' approaches.

Is past life regression therapy ethical?
Andrade, Gabriel
2017-01-01
Past life regression therapy is used by some physicians in cases with some mental diseases. Anxiety disorders, mood disorders, and gender dysphoria have all been treated using life regression therapy by some doctors on the assumption that they reflect problems in past lives. Although it is not supported by psychiatric associations, few medical associations have actually condemned it as unethical. In this article, I argue that past life regression therapy is unethical for two basic reasons. First, it is not evidence-based. Past life regression is based on the reincarnation hypothesis, but this hypothesis is not supported by evidence, and in fact, it faces some insurmountable conceptual problems. If patients are not fully informed about these problems, they cannot provide an informed consent, and hence, the principle of autonomy is violated. Second, past life regression therapy has the great risk of implanting false memories in patients, and thus, causing significant harm. This is a violation of the principle of non-malfeasance, which is surely the most important principle in medical ethics.

Full Text Available According to life history theory, physiological and ecological traits and parameters influence an individual's life history and thus, ultimately, its lifespan. Mating and reproduction are costly activities, and in a variety of model organisms, a negative correlation of longevity and reproductive effort has been demonstrated. We are employing the annual killifish Nothobranchius furzeri as a vertebrate model for ageing. N. furzeri is the vertebrate displaying the shortest known lifespan in captivity with particular strains living only three to four months under optimal laboratory conditions. The animals show explosive growth, early sexual maturation and age-dependent physiological and behavioural decline. Here, we have used N. furzeri to investigate a potential reproduction-longevity trade-off in both sexes by means of gender separation. Though female reproductive effort and offspring investment were significantly reduced after separation, as investigated by analysis of clutch size, eggs in the ovaries and ovary mass, the energetic surplus was not reallocated towards somatic maintenance. In fact, a significant extension of lifespan could not be observed in either sex. This is despite the fact that separated females, but not males, grew significantly larger and heavier than the respective controls. Therefore, it remains elusive whether lifespan of an annual species evolved in periodically vanishing habitats can be prolonged on the cost of reproduction at all.

Doesn't it the quantum mechanics separable?; Es no separable la mecanica cuantica?
Energy Technology Data Exchange (ETDEWEB)
Patino Jaidar, Erick Leonardo [Universidad Nacional Autonoma de Mexico, Mexico, D. F. (Mexico)
2001-04-01
Since its beginning, quantum mechanics has been proposed as a non-separable theory, however, this has been a controversial issue. The arguments with or against the non-local character of the quantum theory has always been closely related to its foundations. Nowadays the general opinions is that non-local effects had been verified and the dead of realism as a philosophical point of view is unavoidable. Nevertheless, the discussion stills open, since the performed experiments rely on very strong and unverified experimental hypothesis. Actually there are realistic and local models which reproduce the experimental results. The main goal of this paper is to expose some of the critics which show that realism has not been rejected, but in fact there are alternative realistic theories which allow deep understanding of the quantum behavior. [Spanish] Desde sus inicios, la mecanica cuantica se ha postulado como una teoria no separable, sin embargo este ha sido siempre un punto generador de gran polemica. Los argumentos a favor o en contra del caracter no local de la teoria cuantica han estado siempre vinculados de manera estrecha con sus fundamentos. La tendencia generalizada a la fecha es pensar que los efectos no separables han sido verificados y que la muerte del realismo como vision filosofica es inevitable. Aun asi, la discusion no ha sido cerrada, puesto que los experimentos realizados se apoyan en hipotesis experimentales muy fuertes no verificadas, lo cual da buenas razones para dudar de ellos. De hecho existen modelos realistas y locales que reproducen los resultados de los experimentos realizados. El principal objetivo de este articulo es exponer algunas de las criticas que demuestran que el realismo no ha sido descartado y que, muy por el contrario, existen teorias realistas alternativas que permiten un entendimiento mucho mas amplio de los fenomenos cuanticos.

Precombustion desulfurization using Microcel{trademark} and multi-gravity separator
Energy Technology Data Exchange (ETDEWEB)
Yoon, R.H.; Luttrell, G.H.; Venkatraman, P. [Virginia Polytechnic Institute and State Univ., Blacksburg, VA (United States)
1994-12-31
Studies conducted at the Center for Coal and Minerals Processing (CCMP) indicate that surface-based processes such as froth flotation are inefficient in removing pyrite from fine coal. This shortcoming has been attributed to the fact that pyrite can become hydrophobic under certain conditions and to the inability of flotation to reject middling particles. To overcome these deficiencies, a new processing scheme has been developed at CCMP which involved the use of the Microcel{trademark} flotation column in combination with a centrifugal flowing-film separator, called a Multi-Gravity Separator (MGS). The flotation column removes ash-forming minerals such as clay, while the MGS is effective in removing pyrite. Preliminary test data obtained with high-sulfur coals shows that this processing scheme can nearly double the pyritic sulfur rejection with little loss in clean coal yield. This article discusses the underlying principles of the new circuit and provides test results obtained using eastern U.S. coals.

Leadership: sad facts and silver linings.
Peters, T J
1979-01-01
The typical CEO has endless interruptions and limited options for action. In addition, he may not even hear about his choices, or any bad news that might require action, until it is almost too late. Finally, any decision he does make will probably require months or years to implement fully. This author suggests that this gloomy picture has another side. In fact, each of these "sad facts" of managerial life can be turned into an opportunity to communicate values and to persuade, and they add up to a new notion of the chief executive's function.

This pilot study used a prospective longitudinal design to compare the effect of adjuvant whole breast radiation therapy (WBRT) versus partial breast radiation therapy (PBRT) on fatigue, perceived stress, quality of life and natural killer cell activity (NKCA) in women receiving radiation after breast cancer surgery. Women (N = 30) with early-stage breast cancer received either PBRT, Mammosite brachytherapy at dose of 34 Gy 10 fractions/5 days, (N = 15) or WBRT, 3-D conformal techniques at dose of 50 Gy +10 Gy Boost/30 fractions, (N = 15). Treatment was determined by the attending oncologist after discussion with the patient and the choice was based on tumor stage and clinical need. Women were assessed prior to initiation of radiation therapy and twice after completion of radiation therapy. At each assessment, blood was obtained for determination of NKCA and the following instruments were administered: Perceived Stress Scale (PSS), Functional Assessment of Cancer Therapy-Fatigue (FACT-F), and Functional Assessment of Cancer Therapy-General (FACT-G). Hierarchical linear modeling (HLM) was used to evaluate group differences in initial outcomes and change in outcomes over time. Fatigue (FACT-F) levels, which were similar prior to radiation therapy, demonstrated a significant difference in trajectory. Women who received PBRT reported progressively lower fatigue; conversely fatigue worsened over time for women who received WBRT. No difference in perceived stress was observed between women who received PBRT or WBRT. Both groups of women reported similar levels of quality of life (FACT-G) prior to initiation of radiation therapy. However, HLM analysis revealed significant group differences in the trajectory of quality of life, such that women receiving PBRT exhibited a linear increase in quality of life over time after completion of radiation therapy; whereas women receiving WBRT showed a decreasing trajectory. NKCA was also similar between therapy

Separator Characteristics for Increasing Performance of Microbial Fuel Cells
Zhang, Xiaoyuan
2009-11-01
Two challenges for improving the performance of air cathode, single-chamber microbial fuel cells (MFCs) include increasing Coulombic efficiency (CE) and decreasing internal resistance. Nonbiodegradable glass fiber separators between the two electrodes were shown to increase power and CE, compared to cloth separators (J-cloth) that were degraded over time. MFCtestswereconductedusing glass fibermatswith thicknesses of 1.0mm (GF1) or 0.4 mm (GF0.4), a cation exchange membrane (CEM), and a J-cloth (JC), using reactors with different configurations. Higher power densities were obtained with either GF1 (46 ± 4 W/m3) or JC (46 ± 1 W/m3) in MFCs with a 2 cm electrode spacing, when the separator was placed against the cathode (S-configuration), rather than MFCs with GF0.4 (36 ± 1 W/m3) or CEM (14 ± 1 W/m3). Power was increased to 70 ± 2 W/m3 by placing the electrodes on either side of the GF1 separator (single separator electrode assembly, SSEA) and further to 150 ± 6 W/m3 using two sets of electrodes spaced 2 cm a part (double separator electrode assembly, DSEA). Reducing the DSEA electrode spacing to 0.3 cm increased power to 696 ± 26 W/m3 as a result of a decrease in the ohmic resistance from 5.9 to 2.2 Ω. The main advantages of a GF1 separator compared to JC were an improvement in the CE from 40% to 81% (S-configuration), compared to only 20-40% for JC under similar conditions, and the fact that GF1 was not biodegradable. The high CE for the GF1 separator was attributed to a low oxygen mass transfer coefficient (ko ) 5.0 x 10-5 cm/s). The GF1 andJCmaterials differed in the amount of biomass that accumulated on the separator and its biodegradability, which affected long-term power production and oxygen transport. These results show that materials and mass transfer properties of separators are important factors for improving power densities, CE, and long-term performance of MFCs. © 2009 American Chemical Society.

Stem cell therapy: the great promise in lung disease.
Siniscalco, Dario; Sullo, Nikol; Maione, Sabatino; Rossi, Francesco; D'Agostino, Bruno
2008-06-01
Lung injuries are leading causes of morbidity and mortality worldwide. Pulmonary diseases such as asthma or chronic obstructive pulmonary disease characterized by loss of lung elasticity, small airway tethers, and luminal obstruction with inflammatory mucoid secretions, or idiopathic pulmonary fibrosis characterized by excessive matrix deposition and destruction of the normal lung architecture, have essentially symptomatic treatments and their management is costly to the health care system.Regeneration of tissue by stem cells from endogenous, exogenous, and even genetically modified cells is a promising novel therapy. The use of adult stem cells to help with lung regeneration and repair could be a newer technology in clinical and regenerative medicine. In fact, different studies have shown that bone marrow progenitor cells contribute to repair and remodeling of lung in animal models of progressive pulmonary hypertension.Therefore, lung stem cell biology may provide novel approaches to therapy and could represent a great promise for the future of molecular medicine. In fact, several diseases can be slowed or even blocked by stem cell transplantation.

[Gestalt therapy, extension of psychoanalysis (author's transl)].
Moreau, A
1980-01-01
Gestalt therapy extends considerably psychoanalysis. 1. Transfer in psychoanalysis allows to work on the disturbed relations which the patient transfers onto his analyst, relations created by the parents and repeated now. The extended transfer in a therapeutic group of life allows to work on the fact that the patient recreates here and now the difficulties he encounters in life. 2. The game of the analyst and the encounter show that beyond transfer and projection, a real encounter may take place, a precious means to create life here and now. 3. The difference between individual therapy and group-therapy is about this: the former is centered on illness, the latter on life; the former helps to understand, the latter to live; the individual talks about facts from the past and from elsewhere and the group lives "here and now", which allows to test feelings, a powerful source of life. 4. A session of group-therapy, as developed here, allows to see how one can find a response to a need or avoid to find a response to it. 5. A comparison-table between psycho-analysis and gestalt shows the difference of method, diagnosis, therapeutic process, therapeutist's attitude and of the position of the patient. 6. Psycho-analysis is perhaps a relay after religion? Several elements make us believe this: tension in contacts, ritual, authority, protection, neutrality, guilty making. 7. To contest or contest one-self has helped me to compare the contester with the psycho-analyst: both contest society, but they don't change their behavior. The gestalt-therapeutist is in a way like a hippie: though contesting society, he brings a change to his way of life, while being closer to life.

Study on the separation effect of high-speed ultrasonic vibration cutting.
Zhang, Xiangyu; Sui, He; Zhang, Deyuan; Jiang, Xinggang
2018-07-01
High-speed ultrasonic vibration cutting (HUVC) has been proven to be significantly effective when turning Ti-6Al-4V alloy in recent researches. Despite of breaking through the cutting speed restriction of the ultrasonic vibration cutting (UVC) method, HUVC can also achieve the reduction of cutting force and the improvements in surface quality and cutting efficiency in the high-speed machining field. These benefits all result from the separation effect that occurs during the HUVC process. Despite the fact that the influences of vibration and cutting parameters have been discussed in previous researches, the separation analysis of HUVC should be conducted in detail in real cutting situations, and the tool geometry parameters should also be considered. In this paper, three situations are investigated in details: (1) cutting without negative transient clearance angle and without tool wear, (2) cutting with negative transient clearance angle and without tool wear, and (3) cutting with tool wear. And then, complete separation state, partial separation state and continuous cutting state are deduced according to real cutting processes. All the analysis about the above situations demonstrate that the tool-workpiece separation will take place only if appropriate cutting parameters, vibration parameters, and tool geometry parameters are set up. The best separation effect was obtained with a low feedrate and a phase shift approaching 180 degrees. Moreover, flank face interference resulted from the negative transient clearance angle and tool wear contributes to an improved separation effect that makes the workpiece and tool separate even at zero phase shift. Finally, axial and radial transient cutting force are firstly obtained to verify the separation effect of HUVC, and the cutting chips are collected to weigh the influence of flank face interference.

The Case for Insurance Reimbursement of Couple Therapy.
Clawson, Robb E; Davis, Stephanie Y; Miller, Richard B; Webster, Tabitha N
2017-08-22
A case is made for why it may now be in the best interest of insurance companies to reimburse for marital therapy to treat marital distress. Relevant literature is reviewed with a considerable focus on the reasons that insurance companies would benefit from reimbursing marital therapy - the high costs of marital distress, the growing link between marital distress and a host of related physical and mental health problems, as well as the availability of empirically supported treatments for marital distress. This is followed by a focus on the major reasons insurance companies cite for not reimbursing marital therapy, along with a discussion of advances in several growing bodies of research to address these concerns. Main arguments include the direct medical offset costs of couple and family therapy (including for high utilizers of health insurance), and the fact that insurance companies already find it cost effective to reimburse for prevention of other health and psychological problems. This is followed by implications for practitioners and researchers. © 2017 American Association for Marriage and Family Therapy.

Angina pectoris: current therapy and future treatment options.
Parikh, Raj; Kadowitz, Philip J
2014-02-01
Angina pectoris is the consequence of an inequality between the demand and supply of blood to the heart. Angina manifests itself as chest pain or discomfort and is a common complaint of patients in the hospital and in the clinic. There are, in fact, roughly half a million new cases of angina per year. Chest pain, while having many etiologies, is generally considered to be most lethal when related to a cardiac cause. In this review, the authors outline the current medical and surgical therapies that are used in the management of angina. Highlights of the various clinical trials that have assisted in the investigation of these therapies are summarized also. Then, the authors provide a focused review of the novel therapy options for angina that are currently being explored. From new medical treatments to revised surgical techniques to the discovery of stem cell therapy, many innovative options are being investigated for the treatment of angina.

Sjogren Syndrome-Gene Therapy and its Prospective
Directory of Open Access Journals (Sweden)
R Rahpeyma
2003-02-01
Full Text Available Sjogren syndrome is one of the autoimmune diseases which is characterized by lymphocytic infiltration to exocrine glands and causes keratoconjunctivitis sicca and xerostomia. Today, a large population, with a majority of women over 40, suffer from this disease and have several complications regarding oral health and reduced life quality such as severe dental caries, painful eyes, olfactory and gustatory deficiency, speech, mastication and swallowing discomforts. Unfortunately, these patients do not respond to the conventional therapies. Nowadays in medical world, which its target is basic therapy and not symptomatic one, several gene therapy approaches, have gained importance in treatment of this apparently incurable diseases. Due to the facts that this disease is the second prevelant autoimmune disease, after rheumatoid arthritis, and the conventional therapies of the disease are all relative and symptomatic, researchers have insisted on the basic and causative therapy through gene transfer more than before. In the Present article, through reviewing 58 references containing recent scientific and investigatory findings it has been tried, to consider the pathogenesis and conventional therapies of this syndrome. Another purpose of this study was to investigate several and potentially very effective gene transfer systems and different theraputic genes (mainly membrane water channels, ione transporter molecules, transcription factors, antifungal proteins and free radical scavengers.

Microporous carbonaceous adsorbents for CO2 separation via selective adsorption
Zhao, Yunfeng
2015-01-01
Selective adsorption of CO2 has important implications for many energy and environment-related processes, which require the separation of CO2 from other gases (e.g. N2 and CH4) with high uptakes and selectivity. The development of high-performance adsorbents is one of the most promising solutions to the success of these processes. The present review is focused on the state-of-the-art of carbon-based (carbonaceous) adsorbents, covering microporous inorganic carbons and microporous organic polymers, with emphasis on the correlation between their textural and compositional properties and their CO2 adsorption/separation performance. Special attention is given to the most recently developed materials that were not covered in previous reviews. We summarize various effective strategies (N-doping, surface functionalization, extra-framework ions, molecular design, and pore size engineering) for enhancing the CO2 adsorption capacity and selectivity of carbonaceous adsorbents. Our discussion focuses on CO2/N2 separation and CO2/CH4 separation, while including an introduction to the methods and criteria used for evaluating the performance of the adsorbents. Critical issues and challenges regarding the development of high-performance adsorbents as well as some overlooked facts and misconceptions are also discussed, with the aim of providing important insights into the design of novel carbonaceous porous materials for various selective adsorption based applications.

Orthodontic Elastic Separator-Induced Periodontal Abscess: A Case Report
Directory of Open Access Journals (Sweden)
Talia Becker
2012-01-01
Full Text Available Aim. Orthodontic elastic bands were proposed as being the source of gingival abscesses that can rapidly lead to bone loss and teeth exfoliation. We report an adolescent, otherwise, healthy patient whose periodontal status was sound. Shortly after undergoing preparations for orthodontic treatment consisting of orthodontic separators, he presented with a periodontal abscess for which there was no apparent etiology. A non-orthoradial X-ray was inconclusive, but an appropriate one revealed a subgingival orthodontic separator as the cause of the abscess. Removal of the separator and thorough scaling led to complete resolution of the abscess, but there was already residual mild damage to the alveolar bone. Summary. Failure to use appropriate imaging to reveal the cause of gingival abscesses can result in the delay of implementing treatment and halting irreversible alveolar bone loss. An inflammatory process restricted to the gingiva and refractive to conventional therapy should raise the possibility of a foreign body etiology.

Advanced research on separating prostate cancer stem cells
International Nuclear Information System (INIS)
Hao Yumei; He Xin; Song Naling
2013-01-01
Prostate cancer is a common malignant tumor in male urinary system,and may easily develop into the hormone refractory prostate cancer which can hardly be cured. Recent studies had found that the prostate cancer stem cells may be the source of the prostate cancer's occurrence,development, metastasis and recurrence. The therapy targeting the prostate cancer stem cells may be the effective way to cure prostate cancer. But these cells is too low to be detected. The difficulty lies in the low separation efficiency of prostate cancer stem cell, so the effectively separating prostate cancer stem cells occupied the main position for the more in-depth research of prostate cancer stem cells. This paper reviews the research progress and existing problems on the several main separating methods of prostate cancer stem cells, includes the fluorescence activated cells sorting and magnetic activated cells sorting based on prostate cancer stem cell surface markers, the side-population sorting and serum-free medium sphere forming sorting based on prostate cancer stem cell's biology.

Centrifugal mass separation in rotating plasmas produced by a coaxial plasma gun
International Nuclear Information System (INIS)
Ikehata, T.; Suzuki, M.; Tanabe, T.; Mase, H.
1989-01-01
Rotating Cu/Zn plasmas produced by a coaxial plasma gun have been applied to plasma centrifuge. A separation factor of up to 10 is measured over a radius of 4 cm when a current of 13 kA and an axial magnetic field of 2.5 kG are applied. Plasma parameters are: rotation frequency ω=1.1x10 6 rad/s, density n∼10 15 cm -3 , and ion temperature T i =10 eV. The separation factor of 2 is attained even in the plasma core where the density is higher than one-half of the peak value. This is attributed to the fact that a strong centrifugal force forms a hollow density profile which gives the density peak at a radius of 2 cm

Optimal placement of FACTS devices using optimization techniques: A review
Gaur, Dipesh; Mathew, Lini
2018-03-01
Modern power system is dealt with overloading problem especially transmission network which works on their maximum limit. Today’s power system network tends to become unstable and prone to collapse due to disturbances. Flexible AC Transmission system (FACTS) provides solution to problems like line overloading, voltage stability, losses, power flow etc. FACTS can play important role in improving static and dynamic performance of power system. FACTS devices need high initial investment. Therefore, FACTS location, type and their rating are vital and should be optimized to place in the network for maximum benefit. In this paper, different optimization methods like Particle Swarm Optimization (PSO), Genetic Algorithm (GA) etc. are discussed and compared for optimal location, type and rating of devices. FACTS devices such as Thyristor Controlled Series Compensator (TCSC), Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM) are considered here. Mentioned FACTS controllers effects on different IEEE bus network parameters like generation cost, active power loss, voltage stability etc. have been analyzed and compared among the devices.

Recent advances in SRS on hydrogen isotope separation using thermal cycling absorption process
Energy Technology Data Exchange (ETDEWEB)
Xiao, X.; Kit Heung, L.; Sessions, H.T. [Savannah River National Laboratory - SRNL, Aiken, SC (United States)
2015-03-15
TCAP (Thermal Cycling Absorption Process) is a gas chromatograph in principle using palladium in the column packing, but it is unique in the fact that the carrier gas, hydrogen, is being isotopically separated and the system is operated in a semi-continuous manner. TCAP units are used to purify tritium. The recent TCAP advances at Savannah River Site (SRS) include compressor-free concept for heating/cooling, push and pull separation using an active inverse column, and compact column design. The new developments allow significantly higher throughput and better reliability from 1/10 of the current production system's footprint while consuming 60% less energy. Various versions are derived in the meantime for external customers to be used in fusion energy projects.

Public fear of vaccination: separating fact from fiction.
Amanna, Ian; Slifka, Mark K
2005-01-01
During the last two centuries, the world has seen a substantial increase in the number and availability of vaccines for the prevention of infectious disease. Smallpox vaccine remains the most celebrated vaccine-related achievement in human history, but worldwide reductions in many other diseases including measles, mumps, rubella, polio, diphtheria, and whooping cough (Bordetella pertussis) also illustrate the power of vaccination in controlling outbreaks of contagious diseases. Ironically, as advances in vaccination successfully limit disease outbreaks, the impact that these infectious agents once had on society becomes marginalized. Public confidence in vaccination may erode because of real or perceived risks associated with immunization, and this in turn may lead to lower vaccination coverage and loss of herd immunity. Here, we will discuss some of the elements associated with public perceptions and fear of vaccination and place these into the context of how deadly several vaccine-preventable childhood diseases can be if vaccination coverage is insufficient.

Fiber and colorectal diseases: Separating fact from fiction
Tan, Kok-Yang; Seow-Choen, Francis
2007-01-01
Whilst fruits and vegetables are an essential part of our dietary intake, the role of fiber in the prevention of colorectal diseases remains controversial. The main feature of a high-fiber diet is its poor digestibility. Soluble fiber like pectins, guar and ispaghula produce viscous solutions in the gastrointestinal tract delaying small bowel absorption and transit. Insoluble fiber, on the other hand, pass largely unaltered through the gut. The more fiber is ingested, the more stools will have to be passed. Fermentation in the intestines results in build up of large amounts of gases in the colon. This article reviews the physiology of ingestion of fiber and defecation. It also looks into the impact of dietary fiber on various colorectal diseases. A strong case cannot be made for a protective effect of dietary fiber against colorectal polyp or cancer. Neither has fiber been found to be useful in chronic constipation and irritable bowel syndrome. It is also not useful in the treatment of perianal conditions. The fiber deficit - diverticulosis theory should also be challenged. The authors urge clinicians to keep an open mind about fiber. One must be aware of the truths and myths about fiber before recommending it. PMID:17696243

Real-time adaptive concepts in acoustics blind signal separation and multichannel echo cancellation
Schobben, Daniel W E
2001-01-01
Blind Signal Separation (BSS) deals with recovering (filtered versions of) source signals from an observed mixture thereof. The term `blind' relates to the fact that there are no reference signals for the source signals and also that the mixing system is unknown. This book presents a new method for blind signal separation, which is developed to work on microphone signals. Acoustic Echo Cancellation (AEC) is a well-known technique to suppress the echo that a microphone picks up from a loudspeaker in the same room. Such acoustic feedback occurs for example in hands-free telephony and can lead to a perceived loud tone. For an application such as a voice-controlled television, a stereo AEC is required to suppress the contribution of the stereo loudspeaker setup. A generalized AEC is presented that is suited for multi-channel operation. New algorithms for Blind Signal Separation and multi-channel Acoustic Echo Cancellation are presented. A background is given in array signal processing methods, adaptive filter the...

New separation technique. Catalytically functionated separation membrane
Energy Technology Data Exchange (ETDEWEB)
Urgami, Tadashi [Kansai Univ., Osaka (Japan)
1989-02-01
This report introduces research examples, showing the fundamental principle of the membrane by separating the catalytically functionated separation membrane into enzyme fixing separation membrane, polymerized metal complex separation membrane and polymer catalyst separation membrane. This membrane can achieve both functions of separation and catalytic reaction simultaneously and has sufficient possibility to combine powerful functions. Enzyme fixing separation membrane is prepared by carrier combination method, bridging method or covering method and the enzyme fixing method with polymerized complex in which enzyme is controlled to prevent the activity lowering as much as possible and enzyme is fixed from an aqueous solution into polymer membrane. This membrane is applied to the continuous manufacturing of invert sugar from cane sugar and adsorption and removing of harmful substances from blood by utilizing both micro-capsuled urease and active carbon. Alginic acid-copper (II) complex membrane is used for the polymerized metal complex membrane and polystyrene sulfonate membrane is used for the polymer catalyst separation membrane. 28 refs., 4 figs., 1 tabs.

Hydroxyurea therapy for sickle cell anemia.
McGann, Patrick T; Ware, Russell E
2015-01-01
Sickle cell anemia (SCA) is a severe, inherited hemoglobin disorder affecting 100,000 persons in the US and millions worldwide. Hydroxyurea, a once daily oral medication, has emerged as the primary disease-modifying therapy for SCA. The accumulated body of evidence over 30 years demonstrates that hydroxyurea is a safe and effective therapy for SCA, but hydroxyurea remains underutilized for a variety of reasons. In this review, we summarize the available evidence regarding the pharmacology, clinical, and laboratory benefits, and safety of hydroxyurea therapy for the treatment of SCA. The purpose of this review is to provide the reader a comprehensive understanding of hydroxyurea and to reinforce the fact that hydroxyurea is a safe and effective medication for the treatment of SCA. In our opinion, hydroxyurea therapy should be considered standard-of-care for SCA, representing an essential component of patient management. Early initiation and broader use of hydroxyurea will alter the natural history of SCA, so affected children can live longer and healthier lives. In addition, hydroxyurea use should be extended to low-resource settings such as sub-Saharan Africa, where the burden of SCA and the need for hydroxyurea is arguably the greatest.

The Accountability Turn in Third Wave Human Rights Fact-Finding
Directory of Open Access Journals (Sweden)
Federica D'Alessandra
2017-04-01
Full Text Available Whereas the characteristics of human rights fact-finding largely vary depending on the typology and scope of the entity that carries it out, consensus seems to be developing that a common set of challenges to human rights fact-finding exists. This is especially so when carried out under United Nations auspices. For example, it has long been acknowledged that the very nature of the institution, sitting as it does at the crossroads of international politics, as well as the seemingly irresolvable tension between calls for human rights protection on the one hand, and State sovereignty on the other, present some structural challenges to human rights fact-finding. Furthermore, issues of coordination between the United Nations and other institutions (such as international governmental and non-governmental organisations, or international tribunals, as well as what some have called a ‘lack of institutional memory’ arguably often feature as regular traits among fact-finding mechanisms. In recent years, a further set of challenges has been added to the mix by additional requirements, featuring increasingly often in mandates, that instruct fact-finding mechanisms to make further determinations of facts (concerning, 'e.g.', the identity of those most responsible for the violations being documented, or the existence of an armed conflict and even consider questions of law ('e.g.' the qualification of the violations as crimes under international law. Building on an expanding body of scholarship on the subject, as well as the author’s own experience with fact-finding efforts sitting at the intersection between traditional international human rights law and international criminal justice, this article argues: (i that human rights fact-finding has evolved in three waves; (ii that the third wave of human rights fact-finding is characterised by an “accountability turn”; and that (iii this turn has brought about an additional set of challenges to the

The First G-APD Cherenkov Telescope is the first Imaging Air Cherenkov Telescope which uses silicon photon detectors (G-APDs aka SiPM) as photo sensors. With more than four years of operation, FACT proved an application of SiPMs is suitable for the field of ground-based gamma-ray astronomy. Due to the stable flux at TeV energies, the Crab Nebula is handled as a ''standard candle'' in Cherenkov astronomy. The analysis of its energy spectrum and comparison with other experiments, allows to evaluate the performance of FACT. A modern analysis chain, based on data stream handling and multivariate analysis methods was developed in close cooperation with the department of computer science at the TU Dortmund. In this talk, this analysis chain and its application are presented. Further to this, results, including the energy spectrum of the Crab Nebula, measured with FACT, are shown.

AutoFACT: An Automatic Functional Annotation and Classification Tool
Directory of Open Access Journals (Sweden)
Lang B Franz
2005-06-01
Full Text Available Abstract Background Assignment of function to new molecular sequence data is an essential step in genomics projects. The usual process involves similarity searches of a given sequence against one or more databases, an arduous process for large datasets. Results We present AutoFACT, a fully automated and customizable annotation tool that assigns biologically informative functions to a sequence. Key features of this tool are that it (1 analyzes nucleotide and protein sequence data; (2 determines the most informative functional description by combining multiple BLAST reports from several user-selected databases; (3 assigns putative metabolic pathways, functional classes, enzyme classes, GeneOntology terms and locus names; and (4 generates output in HTML, text and GFF formats for the user's convenience. We have compared AutoFACT to four well-established annotation pipelines. The error rate of functional annotation is estimated to be only between 1–2%. Comparison of AutoFACT to the traditional top-BLAST-hit annotation method shows that our procedure increases the number of functionally informative annotations by approximately 50%. Conclusion AutoFACT will serve as a useful annotation tool for smaller sequencing groups lacking dedicated bioinformatics staff. It is implemented in PERL and runs on LINUX/UNIX platforms. AutoFACT is available at http://megasun.bch.umontreal.ca/Software/AutoFACT.htm.

Patient-reported outcomes (PRO) represent an important measure of cancer therapy effect. For patients with metastatic epidural spinal cord compression (MESCC), hybrid therapy using separation surgery and stereotactic radiosurgery preserves neurologic function and provides tumor control. There is currently a paucity of data reporting PRO after such combined modality therapy for MESCC. Delineation of hybrid surgery-radiosurgery therapy effect on PRO validates the hybrid approach as an effective therapy resulting in meaningful symptom relief. Brief Pain Inventory (BPI) and MD Anderson Symptom Inventory-Spine Tumor (MDASI-SP), PROs validated in the cancer population, were prospectively collected. Patients with MESCC who underwent separation surgery followed by stereotactic radiosurgery were included. Separation surgery included a posterolateral approach without extensive cytoreductive tumor excision. A median postoperative radiosurgery dose of 2700 cGy was delivered. The change in PRO 3 months after the hybrid therapy represented the primary study outcome. Preoperative and postoperative evaluations were analyzed using the Wilcoxon signed-rank test for matched pairs. One hundred eleven patients were included. Hybrid therapy resulted in a significant reduction in the BPI items "worst" and "right now" pain ( P < .0001), and in all BPI constructs (severity, interference with daily activities, and pain experience, P < .001). The MDASI-SP demonstrated reduction in spine-specific pain severity and interference with general activity ( P < .001), along with decreased symptom interference ( P < .001). Validated PRO instruments showed that in patients with MESCC, hybrid therapy with separation surgery and radiosurgery results in a significant decrease in pain severity and symptom interference. These prospective data confirm the benefit of hybrid therapy for treatment of MESCC and should facilitate referral of patients with MESCC for surgical evaluation.

The duration of first-line and the timing of second-line therapy for advanced non-small cell lung cancer has been an area of recent investigation. Five trials have been performed that have investigated shorter (3-4 cycles) versus longer duration of platinum-based therapy; four trials revealed an equivalent overall survival with the shorter duration of therapy, and one trial revealed superior survival with the longer duration of therapy. The toxicity and quality of life data has either been equivalent or favored the shorter duration of therapy. Two trials have investigated the timing of a second-line therapy after completion of four cycles of platinum-based therapy versus the standard treatment paradigm of initiating second-line therapy upon disease progression. Both of these trials have revealed a statistically significant improvement in the progression-free survival, and a trend towards improved survival for the earlier use of second-line therapy. Only 50 to 60% of patients on the standard treatment arm initiated second-line therapy, and the promising results observed are most likely related to the fact that a higher percentage of patients received second-line therapy on the experimental arm. Several trials have investigated maintenance chemotherapy, and these trials have not revealed a survival benefit probably due to the fact that many patients experience disease progression or unacceptable toxicity during the initial or maintenance therapy. The addition of a targeted agent (bevacizumab or cetuximab) to the initial chemotherapy and the continuation of the targeted agent after completion of the chemotherapy have yielded superior overall survival in comparison to chemotherapy alone. The incremental benefit of the maintenance therapy with the targeted agent is unknown.

The adoption of two-unit separation cells in radioactive rare gas membrane separation equipment enhances the separation factor, but increases the required membrane area and compressive power. An analytical economic evaluation was undertaken to compare the conventional separation cell with the two-unit separation cells, adopting as parameters the number of cascade stages, the membrane area and the operating power requirements. This paper describes the models used for evaluating the separation performance and the economics of cascade embodying these different concepts of separation cell taken up for study, and the results obtained for the individual concepts are mutually compared. It proved that, in respect of the number required of cascade stages, of operating power requirements and of the annual expenditure, better performance could always be expected of the two-unit separation cells as compared with the conventional separation cell, at least in the range of parameters adopted in this study. As regards the minimum membrane area, the conventional separation cell and the series-type separation cell yielded almost the same values, with the parallel-type separation cell falling somewhat behind.

[Achievements and enlightenment of modern acupuncture therapy for stroke based on the neuroanatomy].
Chen, Li-Fang; Fang, Jian-Qiao; Chen, Lu-Ni; Wang, Chao
2014-04-01
Up to now, in the treatment of stroke patients by acupuncture therapy, three main representative achievements involving scalp acupuncture intervention, "Xing Nao Kai Qiao" (restoring consciousness and inducing resuscitation) acupuncture technique and nape acupuncture therapy have been got. Regarding their neurobiological mechanisms, the scalp acupuncture therapy is based on the functional localization of the cerebral cortex, "Xing Nao Kai Qiao" acupuncture therapy is closely related to nerve stem stimulation, and the nape acupuncture therapy is based on the nerve innervation of the regional neck-nape area in obtaining therapeutic effects. In fact, effects of these three acupuncture interventions are all closely associated with the modern neuroanatomy. In the treatment of post-stroke spastic paralysis, cognitive disorder and depression with acupuncture therapy, modern neuroanatomical knowledge should be one of the key theoretical basis and new therapeutic techniques should be explored and developed continuously.

[Focused ultrasound therapy: current status and potential applications in neurosurgery].
Dervishi, E; Aubry, J-F; Delattre, J-Y; Boch, A-L
2013-12-01
High Intensity Focused Ultrasound (HIFU) therapy is an innovative approach for tissue ablation, based on high intensity focused ultrasound beams. At the focus, HIFU induces a temperature elevation and the tissue can be thermally destroyed. In fact, this approach has been tested in a number of clinical studies for the treatment of several tumors, primarily the prostate, uterine, breast, bone, liver, kidney and pancreas. For transcranial brain therapy, the skull bone is a major limitation, however, new adaptive techniques of phase correction for focusing ultrasound through the skull have recently been implemented by research systems, paving the way for HIFU therapy to become an interesting alternative to brain surgery and radiotherapy.

Considering FACTS in Optimal Transmission Expansion Planning
Directory of Open Access Journals (Sweden)
K. Soleimani
2017-10-01
Full Text Available The expansion of power transmission systems is an important part of the expansion of power systems that requires enormous investment costs. Since the construction of new transmission lines is very expensive, it is necessary to choose the most efficient expansion plan that ensures system security with a minimal number of new lines. In this paper, the role of Flexible AC Transmission System (FACTS devices in the effective operation and expansion planning of transmission systems is examined. Effort was taken to implement a method based on sensitivity analysis to select the optimal number and location of FACTS devices, lines and other elements of the transmission system. Using this method, the transmission expansion plan for a 9 and a 39 bus power system was performed with and without the presence of FACTS with the use of DPL environment in Digsilent software 15.1. Results show that the use of these devices reduces the need for new transmission lines and minimizes the investment cost.

Descriptive analysis of YouTube music therapy videos.
Gooding, Lori F; Gregory, Dianne
2011-01-01
The purpose of this study was to conduct a descriptive analysis of music therapy-related videos on YouTube. Preliminary searches using the keywords music therapy, music therapy session, and "music therapy session" resulted in listings of 5000, 767, and 59 videos respectively. The narrowed down listing of 59 videos was divided between two investigators and reviewed in order to determine their relationship to actual music therapy practice. A total of 32 videos were determined to be depictions of music therapy sessions. These videos were analyzed using a 16-item investigator-created rubric that examined both video specific information and therapy specific information. Results of the analysis indicated that audio and visual quality was adequate, while narrative descriptions and identification information were ineffective in the majority of the videos. The top 5 videos (based on the highest number of viewings in the sample) were selected for further analysis in order to investigate demonstration of the Professional Level of Practice Competencies set forth in the American Music Therapy Association (AMTA) Professional Competencies (AMTA, 2008). Four of the five videos met basic competency criteria, with the quality of the fifth video precluding evaluation of content. Of particular interest is the fact that none of the videos included credentialing information. Results of this study suggest the need to consider ways to ensure accurate dissemination of music therapy-related information in the YouTube environment, ethical standards when posting music therapy session videos, and the possibility of creating AMTA standards for posting music therapy related video.

Ion mobility spectrometry (IMS) is a widely used analytical technique for rapid molecular separations in the gas phase. Though IMS alone is useful, its coupling with mass spectrometry (MS) and front-end separations is extremely beneficial for increasing measurement sensitivity, peak capacity of complex mixtures, and the scope of molecular information available from biological and environmental sample analyses. In fact, multiple disease screening and environmental evaluations have illustrated that the IMS-based multidimensional separations extract information that cannot be acquired with each technique individually. This review highlights three-dimensional separations using IMS-MS in conjunction with a range of front-end techniques, such as gas chromatography, supercritical fluid chromatography, liquid chromatography, solid-phase extractions, capillary electrophoresis, field asymmetric ion mobility spectrometry, and microfluidic devices. The origination, current state, various applications, and future capabilities of these multidimensional approaches are described in detail to provide insight into their uses and benefits.

Causal and causally separable processes
Oreshkov, Ognyan; Giarmatzi, Christina
2016-09-01
The idea that events are equipped with a partial causal order is central to our understanding of physics in the tested regimes: given two pointlike events A and B, either A is in the causal past of B, B is in the causal past of A, or A and B are space-like separated. Operationally, the meaning of these order relations corresponds to constraints on the possible correlations between experiments performed in the vicinities of the respective events: if A is in the causal past of B, an experimenter at A could signal to an experimenter at B but not the other way around, while if A and B are space-like separated, no signaling is possible in either direction. In the context of a concrete physical theory, the correlations compatible with a given causal configuration may obey further constraints. For instance, space-like correlations in quantum mechanics arise from local measurements on joint quantum states, while time-like correlations are established via quantum channels. Similarly to other variables, however, the causal order of a set of events could be random, and little is understood about the constraints that causality implies in this case. A main difficulty concerns the fact that the order of events can now generally depend on the operations performed at the locations of these events, since, for instance, an operation at A could influence the order in which B and C occur in A’s future. So far, no formal theory of causality compatible with such dynamical causal order has been developed. Apart from being of fundamental interest in the context of inferring causal relations, such a theory is imperative for understanding recent suggestions that the causal order of events in quantum mechanics can be indefinite. Here, we develop such a theory in the general multipartite case. Starting from a background-independent definition of causality, we derive an iteratively formulated canonical decomposition of multipartite causal correlations. For a fixed number of settings and

The early detection of upper limb complications is important in women operated on for breast cancer. The "FACT-B+4-UL" questionnaire, a specific variant of the Functional Assessment of Cancer Therapy-Breast (FACT-B) is available among others to measure the upper limb function. The Spanish version of the upper limb subscale of the FACT-B+4 was validated in a prospective cohort of 201 women operated on for breast cancer (factor analysis, internal consistency, test-retest reliability, construct validity and sensitivity to change were determined). Its predictive capacity of subsequent lymphoedema and other complications in the upper limb was explored using logistic regression. This subscale is unifactorial and has a great internal consistency (Cronbach's alpha: 0.87), its test-retest reliability and construct validity are strong (intraclass correlation coefficient: 0.986; Pearson's R with "Quick DASH": 0.81) as is its sensitivity to change. It didn't predict the onset of lymphedema. Its predictive capacity for other upper limb complications is low. FACT-B+4-UL is useful in measuring upper limb disability in women surgically treated for breast cancer; but it does not predict the onset of lymphoedema and its predictive capacity for others complications in the upper limb is low.

Small cell carcinoma is a rare malignant tumor of the larynx. Since this lesion was first described, only 58 cases have been reported in the literature. Between December 1985 and March 1992, five patients with small cell carcinoma of the larynx were treated at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. One patient was treated with radiation therapy alone, three patients with chemotherapy and radiation therapy, and one patient with surgery, chemotherapy and radiation therapy. Local and distant control was achieved in only one patient who was observed for 12 months after radiation therapy. Four patients died, one of local disease without distant metastasis at 6 months following treatment, one of local and distant disease at 53 months after radiation therapy, and two of distant metastasis without local disease at 22 and 36 months following treatment. In spite of the fact that only one of the five patients presented in this series is alive and free of disease 12 months following treatment, recent published information suggests that chemotherapy and radiotherapy are currently the most effective form of therapy for small cell carcinoma of the larynx. 16 Refs

Social constructivism and positive epistemology: On establishing of scientific facts
Directory of Open Access Journals (Sweden)
Brdar Milan
2009-01-01
Full Text Available In this article author is dealing with the problem of genesis and establishing of scientific fact. In the first part is given philosophical treatment of the problem and its futility, for the reason given in Minhausen trilema as a conclusion of this kind of treatment. Second part of the article contains the review of Ludvik Fleck's positive epistemology and of social constructivism. After the short historical review of the roots of social constructivism in the Mannheim's sociology of knowledge, author describes how it goes with erstablishing of scientific fact. Solution is set forth by elaboration of triad physis-nomos-logos within the constitutive elements of society known as authority-institution-reason-discourse. Author's concluding thesis claims that there is no fact without convention, i.e. that nature and scientific fact are connected by institution (scientific or social. It does not mean that there is no sound established facts but that obstacle toward it is provided just with institutional mediation that make condition of possibility of very truth. Therefore, the question: what among known facts are really truthful amounts to eternal problem of science and common sense in every epoch of history. .

2007-05-01
Women who do not have a cooperative partner cannot complete the usual therapeutic process in the treatment of vaginismus, because they cannot progress to the stage of practicing the insertion of the man partner's fingers and the insertion of a penis. To compare traditional couple therapy with therapy utilizing a surrogate partner. The study was controlled and retrospective. Data were obtained from the treatment charts of patients who had come to the clinic for treatment of vaginismus. Sixteen vaginismus patients who were treated with a man surrogate partner were compared with 16 vaginismus patients who were treated with their own partners. Successful pain-free intercourse upon completion of therapy. One hundred percent of the surrogate patients succeeded in penile-vaginal intercourse compared with 75% in the couples group (P = 0.1). All surrogate patients ended the therapy because it was fully successful, compared with 69% in the couples group. Twelve percent of the couples group ended the therapy because it failed, and 19% because the couples decided to separate. Treating vaginismus with a man surrogate partner was at least as effective as couple therapy. Surrogate therapy may be considered for vaginismus patients who have no cooperative partner.

Radiation therapy and late reactions in normal tissues
International Nuclear Information System (INIS)
Aoyama, Takashi; Kuroda, Yasumasa
1998-01-01
Recent developments in cancer therapy have made us increasingly aware that the quality of life of a patient is as valuable as other benefits received from therapy. This awareness leads to an emphasis on organ and/or function preservation in the course of therapy. In line with this new thinking, greater consideration is placed on radiation therapy as an appropriate modality of cancer therapy. Possible complications in normal tissues, especially those of late reaction type after the therapy must be overcome. This review, therefore, focuses on recent progress of studies on mechanisms of the complications of the late reaction type. An observation of a clinical case concerning a late reaction of spinal cord (radiation myelopathy) and surveys of experimental studies on the mechanisms of late reactions (including radiation pneumonitis and lung fibrosis, and radiation response of vascular endothelial cells) provide a hypothesis that apoptosis through the pathway starting with radiation-induced sphingomyelin hydrolysis may play an important role in causing a variety of late reactions. This insight is based on the fact that radiation also activates protein kinase C which appears to block apoptosis. The mechanisms of late reactions, therefore, may involve a balance between radiation-induced apoptotic death and its down regulation by suppressor mechanisms through protein kinase C. (author)

Full Text Available Introduction: Among musculoskeletal disorders knee Osteoarthritis (OA is exceedingly prevailing articular disorder affecting people and it is a major cause of disability and socioeconomic burden. It is more common in women than men. Entities with knee OA must often undergo a variety of problems, such as pain and tenderness in joints, movement limitation, crepitus on movement, swelling, recurrent effusion, and local inflammation which ultimately leads to limitation in physical function, like lack of ability to perform Activities of Daily Living (ADL or Instrumental Activities of Daily Living (IADL. For reducing knee pain in osteoarthritis several conventional treatment methods are used world widely but most extensively used in our country are pharmacologic and physical therapy. The objective of the study is to find out the effectiveness of Manual therapy verses Exercise therapy for the management of knee osteoarthritis. Methods: Sixty patients including both male and female with mean age (51years and SD of (5.1 were enrolled in the study and divided randomly in to two groups. Those who were assigned as group A had received Manual therapy and those who were assigned as group B had received Exercise therapy. Participants had received three treatment sessions of 30 min per week for consecutive 4 weeks. OUTCOME MEASURE: WOMAC index score for pain, stiffness and physical function was used to evaluate the baseline score and treatment effects after 12 therapy sessions. Results: Study showed significant improvement in both groups before and after the treatment but in comparison manual therapy group showed significant results with respect to pain subscale (p=0.003 and physical function subscale (p=0.004. Conclusion: Significant difference found between manual therapy and exercise therapy treatment approaches in treating knee osteoarthritis. Findings of this study revealed the fact that short term treatment sessions of manual therapy were superior to

Higher-order relationship between eigen-value separation and static flux tilts
International Nuclear Information System (INIS)
Beckner, W.D.
1975-01-01
Spatial kinetics phenomena in nuclear reactors, such as xenon-induced spatial flux oscillations, are currently being analyzed using the higher harmonic solutions to the static reactor balance equation. An important parameter in such an analysis is a global quantity called eigenvalue separation. It is desirable to be able to experimentally measure this parameter in power reactors in order to confirm design calculations. Since spatial distortions in the flux shape depend on the eigenvalue separation of the reactor, an attempt has been made previously to use this fact as a means of measuring the parameter. It was postulated that an induced flux distortion or ''static flux tilt'' could be measured and theoretically related to eigenvalue separation. Unfortunately, the behavior of experimental data did not exactly agree with theoretical predictions, and values of the parameter found using the original static flux tilt technique were consistently low. The theory has been re-evaluated here and the previously observed discrepancy eliminated. Techniques have been also developed to allow for more accurate interpretation of experimental data. In order to make the method applicable to real systems, the theory has been extended to two spatial dimensions; extension to three dimensions follows directly. Possible trouble areas have been investigated, and experimental procedures for use of the technique to measure the eigenvalue separation in power reactors are presented

Purpose: To determine the effects of patient separation on absolute dose and dose distribution in patients undergoing pelvic radiotherapy on TomoTherapy. Methods: An Alderson RANDO phantom with 4cm of bolus was imaged on a CT simulator and the resulting scans were contoured as a whole pelvic case. Using TomoTherapy Planning Station, the plan was designed to give 45 Gy to 95% of the treatment volume in 25 fractions. TomoTherapy MVCT scans were performed on the RANDO phantom with 2cm and 4cm of bolus removed to simulate visible changes in a patient’s anatomy. The MVCT images were rigidly registered with planning CT images on TomoTherapy Planned Adaptive. The original fluence was recalculated on the MVCT images and changes in dose distribution due to patient separation were quantified by the changes in DVHs for the target volume and the organs at risk. Results: Patient separation difference equivalent to 2cm and 4cm in anterior-posterior direction resulted in an increase of the PTV D50 and maximum PTV dose of 5.6%, 6.2% for 2cm and 7.7%, 10.4% for 4cm, respectively. For the 2cm change, D50 and maximum doses to organs at risk increased by 6.5%, 7.1% in the bladder, 4.9%, 4.8% in the rectum, and 5.3%, 6.6% in the bowel. For the 4cm change, D50 and maximum doses increased by 10.7%, 12.2% in the bladder, 5.9%, 6.1% in the rectum, and 7.7%, 10.1% in the bowel. Conclusion: This research indicates that, without any changes to the structures, patient separation in the anterior-posterior direction can affect the dose distribution for the PTV and organs at risk. These results can assist physicians in determining if obtaining a new CT simulation set and replanning is necessary for pelvic patients on TomoTherapy.

The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a quality of life (QOL) assessment tool that was originally developed for use in patients with primary brain tumors. However, the tool has also been used to assess QOL in patients with metastatic brain tumors. The purpose of this study is to compare the differences in QOL responses as assessed by the FACT-Br in patients with primary and metastatic brain neoplasms. A systematic literature search was conducted using the OvidSP platform in MEDLINE (1946 to July Week 2 2012) and EMBASE (1980 to 2012 Week 28). Articles in which the FACT-Br was used as a QOL assessment for patients with malignant brain tumors (both primary and metastatic) were included in the study. The weighted means of FACT-Br subscale and overall scores were calculated for the studies. To compare these scores, weighted analysis of variance was conducted and PROC GLM was performed for the data. A P-value of Br for assessment of QOL were identified. Social and functional well-being were significantly better in patients with primary brain tumors (weighted mean score of 22.2 vs. 10.7, P = 0.0026, 16.9 vs. 6.2, P = 0.0025, respectively). No other scale of the FACT-Br was significantly different between the two groups and the performance status of patients included in both groups was similar. Patients with primary brain cancer seemed to have better social and functional well-being scores than those with metastatic brain tumors. Other QOL domains were similar between these two groups. However, the heterogeneity in the included studies and the low sample size of included samples in patients with metastatic brain tumors could have confounded our findings.

Patients with cancer frequently suffer from emotional distress, characterized by psychological symptoms such as anxiety or depression. The presence of psychological symptoms combined with the complex nature of oncology processes can negatively impact patients' quality of life. We aimed to determine the impact of a relaxation protocol on improving quality of life in a sample of oncological patients treated in the Spanish National Public Health System. We conducted a multicenter interventional study without a control group. In total, 272 patients with different oncologic pathologies and showing symptoms of anxiety were recruited from 10 Spanish public hospitals. The intervention comprised abbreviated progressive muscle relaxation training, according to Bernstein and Borkovec. This was followed by weekly telephone calls to each patient over a 1-month period. We collected sociodemographic variables related to the disease process, including information about mental health and the intervention. Patients' quality of life was assessed using the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire. Bivariate and univariate analyses were performed, along with an analysis of multiple correspondences to identify subgroups of patients with similar variations on the FACT-G. Patients showed statistically significant improvements on the FACT-G overall score (W = 16806; pPatients with cancer who learned and practiced abbreviated progressive muscle relaxation experienced improvement in their perceived quality of life as measured by the FACT-G. Our findings support a previous assumption that complementary techniques (including relaxation techniques) are effective in improving the quality of life of patients with cancer.

David Hume argued that ought cannot be derived from is . That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume's words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.

The Use of Dialectical Behavior Therapy (DBT) in Music Therapy: A Sequential Explanatory Study.
Chwalek, Carolyn M; McKinney, Cathy H
2015-01-01
There are published examples of how dialectical behavior therapy (DBT) and music therapy are effectively being used as separate therapies in the treatment of individuals with a variety of mental health disorders. However, research examining DBT-informed music therapy is limited. The purpose of this study was to determine whether music therapists working in mental health settings are implementing components of DBT in their work, and if so, how and why; and if not, why not and what is their level of interest in such work. We used a sequential explanatory mixed-methods research design implemented in two phases. Phase 1 was a quantitative survey of board-certified music therapists (n=260). Due to a low survey response rate (18%), and to enhance the validity of the findings, Phase 2, an embedded qualitative procedure in the form of interviews with clinicians experienced in the DBT approach, was added to the study. Both survey and interviews inquired about DBT training, use of DBT-informed music therapy, music therapy experiences used to address DBT skills, and experiences of implementing DBT-informed music therapy. Respondents indicating they implement DBT-informed music therapy (38.3%) are using components and adaptations of the standard DBT protocol. Advantages of implementing DBT-informed music therapy were identified, and more than half of the respondents who do not implement DBT in their music therapy practice also perceived this work as at least somewhat important. Disadvantages were also identified and support the need for further research. Components of DBT are used in music therapy and are valued, but there is a lack of empirical evidence to inform, refine, and guide practice. © the American Music Therapy Association 2015.

A combination of bioleaching and electromagnetic separation in the treatment of quartz sands
Directory of Open Access Journals (Sweden)
Lovás Michal
2006-12-01
Full Text Available This contribution deals with the treatment of Slovakian eolic quartz sands by bioleaching and magnetic separation with the aim to remove iron. The X-ray study of sand patterns confirms that quartz occurs as a dominant mineral. Accompanying minerals are represented by smectite and feldspars. As to the sample of unground sand, bacterial leaching resulted in a Fe2O3 reduction to the content of 0.13 %. Similarly, in case of ground sample, the Fe2O3 content was decreased to the value of 0.19 %. Thus, biological leaching removed 60 % of Fe and by following leaching by oxalic acid total the iron removal was 70.5 %. Finally, the application of magnetic separation resulted in the total iron removal of 93 % and, in such combined way, the prepared product contained 0.024 % of Fe2O3. Achieved results on the iron removal points to the fact that the combination of leaching and magnetic separation enables to obtain a product usable in glass industry.

In this work techniques for the location of FACTS devices (Flexible Systems of AC Transmission) in a multi-machine power system in order to improve the electromechanical transient behavior is presented. In the first part, a brief introduction is presented about the FACTS devices, in which are mentioned some of the main characteristics, classification and advantages that their utilization represents. In the next part, the formulation of the matrix of state in the context of machine-infinite bar considering the possibility of including a power system stabilizer is developed. Later the formulation is extended to a multi-machine system. Additionally the form of including a series capacitor controlled by thyristors (TCSC) as well as a unified controller of power flows (UPFC) is analyzed. An analysis of the UPFC is carried out in conditions of stationary and dynamic state in a system machine-infinite bar in order to know its operating characteristics and its capacity for dampening power oscillations through its entrances of control when using local signals. In the last part of the work a methodology is proposed to attack the problem of the location of FACTS devices, which is based in the technique of response to the system frequency. In order to validate this proposal some cases of study are used and the results obtained with the ones provided by other techniques are compared. Also some auxiliary means are proposed for obtaining the feasible locations utilizing other mathematical tools such as the singular values and the sensitivities. Finally, simulations in the time are carried out to corroborate the results obtained.

Unseen Suffering - Therapy for Traumatized Refugee Children In March 2015 the psychological counselling service (Psychologische Familien- und Lebensberatung) of Caritas Ulm initiated a psychotherapy project for traumatized minor refugees. Besides individual and group therapy, networking and qualification of qualified personnel and volunteers, in autumn 2015 we started offering our services on-site in a large collective accommodation for asylum seekers in Ulm. This was mainly because - in contrast to unaccompanied, mostly adolescent, minor refugees - our services appeared to reach children only by chance. In our opinion this is mostly due to the fact that children's suffering is often far less noticed. This paper describes our first year's project work, followed by reports on the use of psychodrama groups with refugee children and on the therapeutic work in a collective accommodation for asylum seekers.

[Etiology and therapy in anorexia nervosa (author's transl)].
Wurst, E
1976-01-01
ASPERGER (1963) mentioned as a very important etiological aspect of anorexia nervosa a desintegration of intellectual and thymical functions causing the fact, that these patients are not able to accept the role of an adult, especially that one of a woman. We discuss that statment in connexion with ERIKSON'S (1974) concept about "ego-identity" ("Ich-Identitat") and "negative-identity" ("negative Identitat"). The pathological family-structure seems to reinforce the situation and the existence of inadequate behavior of patients with anorexia nervosa, who are often introverted and predestinated for conditioning. The therapy of these patients should focuse on the development of ego-identity, including the treatment of the family members, the modification of the inadapted behavior and a special endocrinological therapy.

Objective: To evaluate the influence of palliative intervention therapy on advanced gastrointestinal carcinoma patients with depression and anxiety before and after the treatment. Methods: 56 advanced gastrointestinal carcinoma patients were selected and treated with intra-arterial perfusion chemotherapy or intra-arterial perfusion chemotherapy with embolization. Curative effects were assessed with the SDS, SAS and FACT-G before and after the treatment. In addition, all patients took self-assessment with SCL-90, comparing with the Chinese norms. Results: SCL-90 scores including the somatization agent, depression agent, and anxiety agent scores of the advanced gastrointestinal carcinoma were higher than those of Chinese norms, with significant difference (P<0.05). After palliative intervention therapy, the scores of SDS and SAS were lower than those before the palliative intervention therapy with significant difference (P< 0.05); and furthermore with an obvious improvement in the scores of FACT-G (P<0.05). Conclusion: Palliative intervention therapy for advanced gastrointestinal carcinoma patients can improve the complaints of depression anxiety and quality of life. (authors)

Separation of Hydrogen Isotopes by Palladium Alloy Membranes Separator
International Nuclear Information System (INIS)
Jiangfeng, S.; Deli, L.; Yifu, X.; Congxian, L.; Zhiyong, H.
2007-01-01
Full text of publication follows: Separation of hydrogen isotope with palladium alloy membranes is one of the promising methods for hydrogen isotope separation. It has several advantages, such as high separation efficiency, smaller tritium inventory, simple separation device, ect. Limited by the manufacture of membrane and cost of gas transportation pump, this method is still at the stage of conceptual study. The relationship between separation factors and temperatures, feed gas components, split ratios have not been researched in detail, and the calculated results of cascade separation have not been validated with experimental data. In this thesis, a palladium alloy membrane separator was designed to further study its separation performance between H 2 and D 2 . The separation factor of the single stage was affected by the temperature, the feed gas component, the split ratio and the gas flow rate, etc. The experimental results showed that the H 2 -D 2 separation factor decreased with the increasing of temperature. On the temperature from 573 K to 773 K, when the feed rate was 5 L/min, the separation factor of 66.2%H 2 - 33.8%D 2 decreased from 2.09 to 1.85 when the split ratio was 0.1 and from 1.74 to 1.52 when the split ratio was 0.2.The separation factor also decreased with the increasing of split ratio. At 573 K and the feed rate of 5 L/min, the separation factor of 15.0%H 2 and 85.0%D 2 decreased from 2.43 to 1.35 with the increasing of split ratio from 0.050 to 0.534,and for 66.2%H 2 -33.8%D 2 , the separation factor decreased from 2.87 to 1.30 with the increasing of split ratio from 0.050 to 0.688. When the separation factor was the biggest, the flow rate of feed gas was in a perfect value. To gain a best separation performance, perfect flow rate, lower temperature and reflux ratio should be chosen. (authors)

A role for FACT in repopulation of nucleosomes at inducible genes.
Directory of Open Access Journals (Sweden)
Warren P Voth
Full Text Available Xenobiotic drugs induce Pleiotropic Drug Resistance (PDR genes via the orthologous Pdr1/Pdr3 transcription activators. We previously identified the Mediator transcription co-activator complex as a key target of Pdr1 orthologs and demonstrated that Pdr1 interacts directly with the Gal11/Med15 subunit of the Mediator complex. Based on an interaction between Pdr1 and the FACT complex, we show that strains with spt16 or pob3 mutations are sensitive to xenobiotic drugs and display diminished PDR gene induction. Although FACT acts during the activation of some genes by assisting in the nucleosomes eviction at promoters, PDR promoters already contain nucleosome-depleted regions (NDRs before induction. To determine the function of FACT at PDR genes, we examined the kinetics of RNA accumulation and changes in nucleosome occupancy following exposure to a xenobiotic drug in wild type and FACT mutant yeast strains. In the presence of normal FACT, PDR genes are transcribed within 5 minutes of xenobiotic stimulation and transcription returns to basal levels by 30-40 min. Nucleosomes are constitutively depleted in the promoter regions, are lost from the open reading frames during transcription, and the ORFs are wholly repopulated with nucleosomes as transcription ceases. While FACT mutations cause minor delays in activation of PDR genes, much more pronounced and significant defects in nucleosome repopulation in the ORFs are observed in FACT mutants upon transcription termination. FACT therefore has a major role in nucleosome redeposition following cessation of transcription at the PDR genes, the opposite of its better-known function in nucleosome disassembly.

Computer models for optimizing radiation therapy
International Nuclear Information System (INIS)
Duechting, W.
1998-01-01
The aim of this contribution is to outline how methods of system analysis, control therapy and modelling can be applied to simulate normal and malignant cell growth and to optimize cancer treatment as for instance radiation therapy. Based on biological observations and cell kinetic data, several types of models have been developed describing the growth of tumor spheroids and the cell renewal of normal tissue. The irradiation model is represented by the so-called linear-quadratic model describing the survival fraction as a function of the dose. Based thereon, numerous simulation runs for different treatment schemes can be performed. Thus, it is possible to study the radiation effect on tumor and normal tissue separately. Finally, this method enables a computer-assisted recommendation for an optimal patient-specific treatment schedule prior to clinical therapy. (orig.) [de

2006-09-01
Full Text Available Text-mining algorithms make mistakes in extracting facts from natural-language texts. In biomedical applications, which rely on use of text-mined data, it is critical to assess the quality (the probability that the message is correctly extracted of individual facts--to resolve data conflicts and inconsistencies. Using a large set of almost 100,000 manually produced evaluations (most facts were independently reviewed more than once, producing independent evaluations, we implemented and tested a collection of algorithms that mimic human evaluation of facts provided by an automated information-extraction system. The performance of our best automated classifiers closely approached that of our human evaluators (ROC score close to 0.95. Our hypothesis is that, were we to use a larger number of human experts to evaluate any given sentence, we could implement an artificial-intelligence curator that would perform the classification job at least as accurately as an average individual human evaluator. We illustrated our analysis by visualizing the predicted accuracy of the text-mined relations involving the term cocaine.

Stylized facts in social networks: Community-based static modeling
Jo, Hang-Hyun; Murase, Yohsuke; Török, János; Kertész, János; Kaski, Kimmo
2018-06-01
The past analyses of datasets of social networks have enabled us to make empirical findings of a number of aspects of human society, which are commonly featured as stylized facts of social networks, such as broad distributions of network quantities, existence of communities, assortative mixing, and intensity-topology correlations. Since the understanding of the structure of these complex social networks is far from complete, for deeper insight into human society more comprehensive datasets and modeling of the stylized facts are needed. Although the existing dynamical and static models can generate some stylized facts, here we take an alternative approach by devising a community-based static model with heterogeneous community sizes and larger communities having smaller link density and weight. With these few assumptions we are able to generate realistic social networks that show most stylized facts for a wide range of parameters, as demonstrated numerically and analytically. Since our community-based static model is simple to implement and easily scalable, it can be used as a reference system, benchmark, or testbed for further applications.

Evidence for Mental Health Occupational Therapy
Directory of Open Access Journals (Sweden)
Danielle Hitch
2015-09-01
Full Text Available This article reports on the evidence for mental health occupational therapy in peer-reviewed journals from 2000 to 2013. Descriptive and inductive methods were used to address this question, with evidence from CINAHL, OTDBase, PSYCInfo, SCOPUS, and Google Scholar® included. Many articles (n = 1,747 were found that met the inclusion and exclusion criteria. A total of 47 different methods were used to develop evidence for mental health occupational therapy, and evidence appeared in 300 separate peer-reviewed journals. It takes on average 7 months for an article to progress from submission to acceptance, and a further 7 months to progress from acceptance to publication. More than 95% of articles published between 2000 and 2002 were cited at least once in the following decade, and around 70% of these citations were recorded in non-occupational therapy journals. The current evidence base for mental health occupational therapy is both substantial and diverse.

New developments of 11C post-accelerated beams for hadron therapy and imaging
Augusto, R. S.; Mendonca, T. M.; Wenander, F.; Penescu, L.; Orecchia, R.; Parodi, K.; Ferrari, A.; Stora, T.
2016-06-01
Hadron therapy was first proposed in 1946 and is by now widespread throughout the world, as witnessed with the design and construction of the CNAO, HIT, PROSCAN and MedAustron treatment centres, among others. The clinical interest in hadron therapy lies in the fact that it delivers precision treatment of tumours, exploiting the characteristic shape (the Bragg peak) of the energy deposition in the tissues for charged hadrons. In particular, carbon ion therapy is found to be biologically more effective, with respect to protons, on certain types of tumours. Following an approach tested at NIRS in Japan [1], carbon ion therapy treatments based on 12C could be combined or fully replaced with 11C PET radioactive ions post-accelerated to the same energy. This approach allows providing a beam for treatment and, at the same time, to collect information on the 3D distributions of the implanted ions by PET imaging. The production of 11C ion beams can be performed using two methods. A first one is based on the production using compact PET cyclotrons with 10-20 MeV protons via 14N(p,α)11C reactions following an approach developed at the Lawrence Berkeley National Laboratory [2]. A second route exploits spallation reactions 19F(p,X)11C and 23Na(p,X)11C on a molten fluoride salt target using the ISOL (isotope separation on-line) technique [3]. This approach can be seriously envisaged at CERN-ISOLDE following recent progresses made on 11C+ production [4] and proven post-acceleration of pure 10C3/6+ beams in the REX-ISOLDE linac [5]. Part of the required components is operational in radioactive ion beam facilities or commercial medical PET cyclotrons. The driver could be a 70 MeV, 1.2 mA proton commercial cyclotron, which would lead to 8.1 × 10711C6+ per spill. This intensity is appropriate using 11C ions alone for both imaging and treatment. Here we report on the ongoing feasibility studies of such approach, using the Monte Carlo particle transport code FLUKA [6,7] to simulate

The basic idea of this project is to study the possibilities to use source separated combustible material for energy conversion in conventional solid fuel boilers (i.e. not municipal waste incineration plants). The project has been carried out in three phases. During phase 1 and 2 a number of fuel analyses of different fractions were carried out. During phase 3 two combustion tests were carried out; (1) a boiler with grate equipped with cyclone, electrostatic precipitator and flue gas condenser, and (2) a bubbling fluidized bed boiler with electrostatic precipitator and flue gas condenser. During the tests source separated paper and plastic packagings were co-fired with biomass fuels. The mixing rate of packagings was approximately 15%. This study reports the results of phase 3 and the conclusions of the whole project. The technical terms of using packaging as fuel are good. The technique is available for shredding both paper and plastic packaging. The material can be co-fired with biomass. The economical terms of using source separated packaging for energy conversion can be very advantageous, but can also form obstacles. The result is to a high degree guided by such facts as how the fuel is collected, transported, reduced in size and handled at the combustion plant. The results of the combustion tests show that the environmental terms of using source separated packaging for energy conversion are good. The emissions of heavy metals into the atmosphere are very low. The emissions are well below the emission standards for waste incineration plants. 35 figs, 13 tabs, 8 appendices

The FaCT project is in progress in Japan for the commercialization of fast reactor cycle system. The development goal of the fuel in the FaCT project is a low-decontaminated TRU homo-recycling in a closed cycle and extension in average discharge burn-up to 150 GWd/t. Research and development on innovative technologies concerning the short process, remote maintenance and cooling system of automatic fuel production equipments, long life cladding material and control of oxygen potential have been conducted in phase I of the FaCT project. As the result of various test including 600 g batch MOX tests, it is concluded that the short process is available to fuel pellet fabrication of the FaCT project. Although cold mock-up tests on test model of some typical process equipments suggest possibilities of remote maintenance of automatic fuel fabrication equipment, it is concluded that it still needs further efforts to judge the operability of the completely remote fabrication for low-decontaminated TRU fuel. A cold mock-up test on fuel pin assembling equipment show that influence of decay heat of MA can be managed by cooling system. Irradiation tests in BOR-60 indicate that 9Cr-ODS possess the satisfactory in-reactor performance as the long life cladding material if homogeneity of alloy element is adequately controlled. Modification of cladding tube fabrication process to ensure homogeneity and further development of measures to control oxygen potential inside the fuel pin are necessary to reach the burn-up target of the FaCT project.

Full Text Available The purpose of this study consists of realizing and offering an overview of the manner in which the principle of separation of powers is consecrated in the constitutions of the EU member states. We thereby aim to prove that there is no direct relationship between the form of government of a state, the expressis verbis constitutional regulation of the principle of separation of powers in the state and its effective observance, for the existence of the last fact being necessary the simultaneous concurrence of more social, economic and political factors at the level of the society as a whole. Also, we aim to offer a perspective as realistic and comprehensive as possible regarding what does the principle of separation of powers imply, mostly from a legal point of view, as well as about the implications that its respecting or lack of it, as the case, does have at the level of a society. Eventually, we hope to provide a relevant academic study regarding the subject of both great topicality and theoretical and practical interest regarding the fundamentals and especially the operating mode of the principle of separation of powers, a study which could serve, if it shall be taken into consideration by the political plan of the state, to the substantiation of some responsible decisions in the ongoing act of exercising the power.

Families and family therapy in Hong Kong.
Tse, Samson; Ng, Roger M K; Tonsing, Kareen N; Ran, Maosheng
2012-04-01
Family therapy views humans not as separate entities, but as embedded in a network of relationships, highlighting the reciprocal influences of one's behaviours on one another. This article gives an overview of family demographics and the implementation of family therapy in Hong Kong. We start with a review of the family demographics in Hong Kong and brief notes on families in mainland China. Demographics show that the landscape has changed markedly in the past decade, with more cross-border marriages, an increased divorce rate, and an ageing overall population - all of which could mean that there is increasing demand for professional family therapy interventions. However, only a limited number of professionals are practising the systems-based approach in Hong Kong. Some possible reasons as to why family therapy is not well disseminated and practised are discussed. These reasons include a lack of mental health policy to support family therapy, a lack of systematic family therapy training, and a shortage of skilled professionals. Furthermore, challenges in applying the western model in Chinese culture are also outlined. We conclude that more future research is warranted to investigate how family therapy can be adapted for Chinese families.

FACT facilitates chromatin transcription by RNA polymerases I and III
DEFF Research Database (Denmark)
Birch, Joanna L; Tan, Bertrand C-M; Panov, Kostya I
2009-01-01
Efficient transcription elongation from a chromatin template requires RNA polymerases (Pols) to negotiate nucleosomes. Our biochemical analyses demonstrate that RNA Pol I can transcribe through nucleosome templates and that this requires structural rearrangement of the nucleosomal core particle....... The subunits of the histone chaperone FACT (facilitates chromatin transcription), SSRP1 and Spt16, co-purify and co-immunoprecipitate with mammalian Pol I complexes. In cells, SSRP1 is detectable at the rRNA gene repeats. Crucially, siRNA-mediated repression of FACT subunit expression in cells results...... in a significant reduction in 47S pre-rRNA levels, whereas synthesis of the first 40 nt of the rRNA is not affected, implying that FACT is important for Pol I transcription elongation through chromatin. FACT also associates with RNA Pol III complexes, is present at the chromatin of genes transcribed by Pol III...

Immunoadsorption with a tryptophan-conjugated column has a limited capacity and reduces fibrinogen. We speculated that immunoadsorption with a selective plasma separator has higher efficiency in removing immunoglobulins than ordinary immunoadsorption without affecting coagulation factors. This study investigated the efficacy of immunoadsorption with a selective plasma separator in vitro. The sieving coefficients, the pool concentration, and the adsorbed amount were investigated serially with up to 5 L of processed plasma. The sieving coefficients of the selective plasma separator were 0.8, 0.5, and 0.1 for albumin, immunoglobulin G (IgG), and factor 13, respectively. The trend of concentrations for the ordinary plasma separator in the pool reached its nadir at 1.5 L and 3.5 L of plasma processed for IgG, IgG1, or IgG2, and IgG3, respectively. However, the volume was doubled for the selective plasma separator. The trends of fibrinogen and factor 13 concentrations differed significantly between two plasma separators. The trends of the absorbed amount were mirror images of the concentration in the pool. Comparison of the peak amount absorbed indicated that the amounts were almost identical between the two separators for IgG, IgG1, and IgG2. On the other hand, the peak amounts were less for albumin, fibrinogen, and IgG3 with the selective plasma separator than with the ordinary separator. Although further investigations about bradykinin are required, immunoadsorption with the selective plasma separator supports the administration of more frequent and intensive treatments to remove IgG1 or IgG2 without affecting coagulation factors. © 2017 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

A proposal for investment recovery of FACTS devices in deregulated electricity markets
International Nuclear Information System (INIS)
Mithulananthan, Nadarajah; Acharya, Naresh
2007-01-01
The paper presents a methodology to quantify the benefits, in terms of monetary values, of FACTS devices when used in deregulated electricity market for congestion management. The proposed methodology is used in the proposal for investment recovery of FACTS devices. Despite the long history of development and mature technology, the practical installations of FACTS devices are still limited. The main reasons for few installations are high investment cost and lack of viable measures to quantify the long list of benefits offered by FACTS device. In this respect, the methodology proposed in the paper provides a promising solution. The proposed methodology is based on establishing pricing schemes with and without FACTS devices using OPF formulation. The volume of market with FACTS devices and the increase in surplus due to them forms the basis of quantifying their benefits. The pricing scheme does not destroy the incentive effect in short run and also makes possible the provision of merchant FACTS. The proposed concept was tested and validated with TCSC in five-bus test system. Result shows that, when TCSC is used to relieve congestion in the system and the investment on TCSC can be recovered.

Scheidt, Douglas; Ault, Erick; Ellis, Robert D.; Gruber, Samuel; Iafrate, Joseph; Kalinowsky, Chris; Kessel, Steven; Reyier, Eric; Snyder, David; Watwood, Stephanie;
2015-01-01
The Florida Atlantic Coast Telemetry (FACT) Array is a collaborative partnership of researchers from 24 different organizations using passive acoustic telemetry to document site fidelity, habitat preferences, seasonal migration patterns, and reproductive strategies of valuable sportfish, sharks, and marine turtles. FACT partners have found that by bundling resources, they can leverage a smaller investment to track highly mobile animals beyond a study area typically restrained in scale by funds and manpower. FACT is guided by several simple rules: use of the same type of equipment, locate receivers in areas that are beneficial to all researchers when feasible, maintain strong scientific ethics by recognizing that detection data on any receiver belongs to the tag owner, do not use other members detection data without permission and acknowledge FACT in publications. Partners have access to a network of 480 receivers deployed along a continuum of habitats from freshwater rivers to offshore reefs and covers 1100 km of coastline from the Dry Tortugas, Florida to South Carolina and extends to the Bahamas. Presently, 49 species, (25 covered by Fisheries Management Plans and five covered by the Endangered Species Act) have been tagged with 2736 tags in which 1767 tags are still active.

NPM1 mutations in therapy-related acute myeloid leukemia with uncharacteristic features
DEFF Research Database (Denmark)
Andersen, Morten Tolstrup; Andersen, Mette Klarskov; Christiansen, D.H.
2008-01-01
Frameshift mutations of the nucleophosmin gene (NPM1) were recently reported as a frequently occurring abnormality in patients with de novo acute myeloid leukemia (AML). To evaluate the frequency of NPM1 mutations in patients with therapy-related myelodysplasia (t-MDS) and therapy-related AML (t......-/-7, the most frequent abnormalities of t-MDS/t-AML, were not observed (P=0.002). This raises the question whether some of the cases presenting NPM1 mutations were in fact cases of de novo leukemia. The close association to class I mutations and the inverse association to class II mutations suggest...

In a placebo-controlled Phase II study of olaparib maintenance therapy (NCT00753545, health-related quality of life was measured using the Functional Assessment of Cancer Therapy – Ovarian (FACT-O questionnaire. Our objective was to generate HSUVs from the FACT-O data using published mapping algorithms. Materials and methods: Algorithms were identified from a review of the literature. Goodness-of-fit and patient characteristics were compared to select the best-performing algorithm, and this was used to generate base-case HSUVs for the intention-to-treat population of the olaparib study and for patients with breast cancer antigen mutations. Results: Four FACT – General (the core component of FACT-O mapping algorithms were identified and compared. Under the preferred algorithm, treatment-related adverse events had no statistically significant effect on HSU (P>0.05. Discontinuation of the study treatment and breast cancer antigen mutation status were both associated with a reduction in HSUVs (–0.06, P=0.0009; and –0.03, P=0.0511, respectively. The mean HSUV recorded at assessment visits was 0.786. Conclusion: FACT – General mapping generated credible HSUVs for an economic evaluation of olaparib. As reported in other studies, different algorithms may produce significantly different estimates of HSUV. For this reason, it is important to test whether the choice of a specific algorithm changes the conclusions of an economic evaluation.

Data analysis unveils a new stylized fact in foreign currency markets
Nacher, J. C.; Ochiai, T.
2012-09-01
The search for stylized facts (i.e., simplified empirical facts) is of capital importance in econophysics because the stylized facts constitute the experimental empirical body on which theories and models should be tested. At the moment they are too few and this is an important limitation to the progress in the field. In this work, we unveil a new stylized fact, which consists of resistance effect and breaking-acceleration effect that implicitly requires a long memory feature in price movement. By analyzing a vast amount of historical data, we demonstrate that the financial market tends to exceed a past (historical) extreme price less often than expected by a classic short-memory model (e.g., Black-Scholes model). We call it resistance effect. However, when the market does it, we predict that the average volatility at that time point will be much higher (accelerates more). It means, in average, volatility accelerates more when the price breaks the highest (lowest) value. We refer to this as breaking-acceleration effect. These observed empirical facts are actually an effect which may arise from technical trading and psychological effects. Taken together, these results indicate that, beyond the predictive capability of this unveiled stylized fact, traditional short-memory models do not faithfully capture the market dynamics.

2010-01-01
Displacement chromatography (DC) is a ascendant technique for hydrogen isotopes separation. The performance of separation materials is a key factor to determine the separation effect of DC. At present,kinds of materials are researched, including palladium materials and non-palladium materials. It is hardly replaceable because of its excellent separation performance, although palladium is expensive. The theory of hydrogen isotopes separation using DC was introduced at a brief manner, while several palladium separation materials were expatiated in detail(Pd/K, Pd-Al 2 O 3 , Pd-Pt alloy). Development direction of separation materials for DC was forecasted elementarily. (authors)

Subtle Implicit Language Facts Emerge from the Functions of Constructions.
Goldberg, Adele E
2015-01-01
Much has been written about the unlikelihood of innate, syntax-specific, universal knowledge of language (Universal Grammar) on the grounds that it is biologically implausible, unresponsive to cross-linguistic facts, theoretically inelegant, and implausible and unnecessary from the perspective of language acquisition. While relevant, much of this discussion fails to address the sorts of facts that generative linguists often take as evidence in favor of the Universal Grammar Hypothesis: subtle, intricate, knowledge about language that speakers implicitly know without being taught. This paper revisits a few often-cited such cases and argues that, although the facts are sometimes even more complex and subtle than is generally appreciated, appeals to Universal Grammar fail to explain the phenomena. Instead, such facts are strongly motivated by the functions of the constructions involved. The following specific cases are discussed: (a) the distribution and interpretation of anaphoric one, (b) constraints on long-distance dependencies, (c) subject-auxiliary inversion, and (d) cross-linguistic linking generalizations between semantics and syntax.

The paper presents theoretical and experimental data concerning mass and heat transfer on B7 ordered packing, at deuterium separation by distillation. The first section of the paper is dedicated to the mass transfer study of hydrogen distillation, while the second section deals with mass and heat transfer in water distillation. A mathematical model was worked out and compared with experimental data, obtained from two laboratory distillation plants for deuterium separation. From the first plant experimental data concerning B7 ordered packing efficiency of hydrogen cryogenic distillation at 250 deg. C level were obtained. Data concerning mass and heat transfer on the same packing in deuterium separation by water vacuum distillation at 60 deg. C level were obtained in the second plant. HUT values, mass and heat transfer coefficients both theoretically evaluated and experimentally determined were found to be comparable with those obtained from chemical industry separation processes. The fact justifies the use of multi-tubular column model for description of transfer processes in distillation columns equipped with B7 structured packing. (authors)

Nylon 6,6 Nonwoven Fabric Separates Oil Contaminates from Oil-in-Water Emulsions.
Directory of Open Access Journals (Sweden)
Ryan A Ortega
Full Text Available Industrial oil spills into aquatic environments can have catastrophic environmental effects. First responders to oil spills along the coast of the Gulf of Mexico in the southern United States have used spunbond nylon fabric bags and fences to separate spilled oil and oil waste from contaminated water. Low area mass density spunbond nylon is capable of sorbing more than 16 times its mass in low viscosity crude oil and more than 26 times its mass in higher viscosity gear lube oil. Nylon bags separated more than 95% of gear lube oil contaminate from a 4.5% oil-in-water emulsion. Field testing of spunbond nylon fences by oil spill first responders has demonstrated the ability of this material to contain the oily contaminate while allowing water to flow through. We hypothesize that the effectiveness of nylon as an oil filter is due to the fact that it is both more oleophilic and more hydrophilic than other commonly used oil separation materials. The nylon traps oil droplets within the fabric or on the surface, while water droplets are free to flow through the fabric to the water on the opposite side of the fabric.

The science of human factors: separating fact from fiction.
Russ, Alissa L; Fairbanks, Rollin J; Karsh, Ben-Tzion; Militello, Laura G; Saleem, Jason J; Wears, Robert L
2013-10-01
Interest in human factors has increased across healthcare communities and institutions as the value of human centred design in healthcare becomes increasingly clear. However, as human factors is becoming more prominent, there is growing evidence of confusion about human factors science, both anecdotally and in scientific literature. Some of the misconceptions about human factors may inadvertently create missed opportunities for healthcare improvement. The objective of this article is to describe the scientific discipline of human factors and provide common ground for partnerships between healthcare and human factors communities. The primary goal of human factors science is to promote efficiency, safety and effectiveness by improving the design of technologies, processes and work systems. As described in this article, human factors also provides insight on when training is likely (or unlikely) to be effective for improving patient safety. Finally, we outline human factors specialty areas that may be particularly relevant for improving healthcare delivery and provide examples to demonstrate their value. The human factors concepts presented in this article may foster interdisciplinary collaborations to yield new, sustainable solutions for healthcare quality and patient safety.

Electron Beam Processing of Polymers: Facts and Opportunities
International Nuclear Information System (INIS)
Gielenz, G.
2006-01-01
Electron Beam (EB) processing of polymers is a well established and mature technology in a multitude of industrial polymer applications for more than 40 years. Constant research effort in combination with emerging tailored EB process technologies, have led to numerous new (niche) applications and products within the past decade. Nonetheless, and despite the fact, that nowadays a large variety of EB and related process equipment is readily available for use by the respective industries, EB processing of polymers still takes up only a small niche in comparison to the overall polymer business. In this lecture the author attempts to present a short overview on the current industrial established and emerging radiation processing applications and the related EB equipment suppliers. Then some selected plastics business facts and figures with a forecast of the global plastics consumption situation up to 2010 will be shown. As a conclusion from these facts, some comments will be deduced, regarding the future potential, attractiveness and economical relevance of irradiation processing technologies in present day competitive global markets

FACTS controllers and the deregulated electric utility environment
International Nuclear Information System (INIS)
Ooi, B. T.; Galiana, F. D.; McGillis, D.; Joos, G.; Marceau, R.
1998-01-01
The concept of Flexible AC Transmission Systems (FACTS) is explored and the potential of power electronic converters to increase flexibility and reliability of modern power systems is explored. Power electronic controllers can reduce the required safety margin in electric power generation capacity through the use of faster controllers based on exploiting the high-power solid-state switches with gate-turn-off capabilities. The FACTS concept makes it possible to postpone the financial investment needed to build more power lines, and also offers a solution to securing the right-of-way to build new lines. Currently available FACTS controllers such as the Static var Compensator (STATCOM) and the Unified Power Flow Controller (UPFC) are described, including their function, structure and relevant implementation issues. Since they can produce the required amount of reactive power independently of line voltage or current, and if equipped with energy storing devices they can supply real power as required, they are a necessary element for the control of power systems in a deregulated environment. 15 refs., 3 figs

In dissolving microneedle (DMN)-mediated therapy, complete and rapid delivery of DMNs is critical for the desired efficacy. Traditional patch-based DMN delivery, however, may fail due to incomplete delivery from insufficient skin insertion or rapid separation of microneedles due to their strong bond to the backing film. Here, we introduce the Troy microneedle, which was created by cyclic contact and drying on the pillar (CCDP), and which enabled simultaneous complete and rapid delivery of DMN. This CCDP process could be flexibly repeated to achieve a specific desired drug dose in a DMN. We evaluated DMN separation using agarose gel, and the Troy microneedle achieved more complete and rapid separation than other, more deeply dipped DMN, primarily because of the Troy's minimal junction between the DMN and pillar. When Troy microneedles were applied to pig cadaver skin, it took only 15 s for over 90% of encapsulated rhodamine B to be delivered, compared to 2 h with application of a traditional DMN patch. In vivo skin penetration studies demonstrated rapid DMN-separation of Troy microneedles still in solid form before dissolution. The Troy microneedle overcomes critical issues associated with the low penetration efficiency of flat patch-based DMN and provides an innovative route for DMN-mediated therapy, combining patient convenience with the desire drug efficacy.

2012-01-01
Background Steam inhalation therapy is often recommended in the treatment of a common cold. However, it has no proven benefit and may in fact have serious adverse side effects in terms of burn injuries. Aim To quantify the human and economic costs of steam inhalation therapy in terms of burn injury. Design and setting A prospective database study of all patients admitted to the burn centres (Beverwijk, Groningen, Rotterdam) and the hospital emergency departments in the Netherlands. Method Number and extent of burn injuries as a result of steam inhalation therapy were analysed, as well as an approximation made of the direct costs for their medical treatment. Results Annually, on average three people are admitted to in one of the Dutch burn centres for burns resulting from steam inhalation therapy. Most victims were children, and they needed skin grafting more often than adults. The total direct medical costs for burn centre and emergency department treatment were €115 500 (£93 000), emotional costs are not reflected. Conclusion As steam inhalation therapy has no proven benefit and the number and extent of complications of this therapy in terms of burn injury are significant, especially in children, steam inhalation therapy should be considered a dangerous procedure and not recommended anymore in professional guidelines and patient brochures.

The main advantage of alkylimidazolium cation-based ionic liquids (ILs) as phase additives in RP-HPLC is believed to be the suppression of deleterious residual free silanols in chemically modified silica stationary phases. However, up to now, the influence of ILs was usually evaluated having in mind a particular IL salt as one compound, not as a specific mixture of cations and anions. This in fact led to some misinterpretation of observed results, very often related to the suppression effect, while in fact caused by the nature of IL anions, which contribute to the elevated chaotropicity of the separation phases. In the present study, we have attempted to consider the effect gained due to the presence of both ionic liquid entities in the mobile phase used for the separation of basic compounds. Tri-cyclic antidepressants (TCAs) were taken as representative analytes. The effect of ILs on the chromatographic separation of TCAs was investigated in comparison to common mobile phase additives and by the presentation of retention factors, tailing factors and theoretical plates. In addition, an overloading study was performed for the IL-based phases for the first time. In general, it was found that the effect of chaotropic hexafluorophosphate anions in ILs is much stronger and opposite to that caused by imidazolium cations. The overloading study gives interesting information on how imidazolium cations affect the separation of cationic analytes. Finally, the usefulness of imidazolium-based ILs as mobile phase modifiers in the RP-HPLC separation of basic compounds was discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

[Health economics and antibiotic therapy].
Leclercq, P; Bigdéli, M
1995-01-01
In the field of antibiotic therapy, particularly the methods of economic evaluation hold one's attention within the wide range of health economics' applications. Several tools allow a comparison of the outcomes of alternative strategies and thereby guide choices to the most appropriate solutions. After a brief recall of the methods classically used to evaluate health care strategy, the authors stress the importance and difficulty of fixing and applying a correct and satisfactory procedure for evaluation. An evaluation example of antibiotic therapy allows to illustrate the application of the principles confronting a field in which competition is intense and economic stakes stay large--a fact which naturally yields to seek after objective decision making criteria. The health care policies drawn by public authorities as well as the marketing strategies of the health sector trade are partly based on such evaluations. If these techniques are not intended for the practitioner in the first place, they should not be indifferent to him since they influence health authorities and thereby indirectly affect the therapeutic freedom of the physician.

Variable-Energy Cyclotron for Proton Therapy Application
Alenitsky, Yu G; Vorozhtsov, A S; Glazov, A A; Mytsyn, G V; Molokanov, A G; Onishchenko, L M
2004-01-01
The requirements to characteristics of the beams used for proton therapy are considered. The operation and proposed cyclotrons for proton therapy are briefly described. The technical decisions of creation of the cyclotron with energy variation in the range 70-230 MeV and with current up to 100 nA are estimated. Taking into account the fact, that the size and cost of the cyclotron are approximately determined by the maximum proton energy, it is realistically offered to limit the maximum proton energy to 190 MeV and to elaborate a cyclotron project with a warm winding of the magnet for acceleration of H^{-} ions. The energy of the extracted protons for each run is determined by a stripped target radius in the vacuum chamber of the accelerator, and the radiation dose field for the patient is created by the external devices using the developed techniques.

Pulmonary hypertension (PH) is a specific clinical group of severe and rare diseases with similar morphological, hemodynamic, and therapeutic characteristics. Despite the fact that there have been international conciliative documents and advances in drug therapy for PH, the long-term prognosis of the.disease in these patients remains rather poor. Clinical trials have demonstrated that bosentan therapy in patients with PH improves pulmonary hemodynamics and exercise endurance and delays the development of the disease. According to the data of long-term studies, as compared to the historical control, bosentan used as a first-line drug can improve survival in PH patients.

Purpose: To evaluate quality of life (QoL), an important outcome owing to poor long-term survival, after stereotactic body radiation therapy (SBRT) to the liver. Methods and Materials: Patients (n=222) with hepatocellular carcinoma (HCC), liver metastases, or intrahepatic cholangiocarcinoma and Child-Pugh A liver function received 24-60 Gy of 6-fraction image-guided SBRT. Prospective QoL assessment was completed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and/or Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep, version 4) questionnaires at baseline and 1, 3, 6, and 12 months after treatment. Ten HCC patients with Child-Pugh B liver function were also treated. Results: The QLQ-C30 was available for 205 patients, and 196 completed the FACT-Hep. No difference in baseline QoL (P=.17) or overall survival (P=.088) was seen between the HCC, liver metastases, and intrahepatic cholangiocarcinoma patients. Appetite loss and fatigue measured by the QLQ-C30 clinically and statistically worsened by 1 month after treatment but recovered by 3 months. At 3 and 12 months after treatment, respectively, the FACT-Hep score had improved relative to baseline in 13%/19%, worsened in 36%/27%, and remained stable in 51%/54%. Using the QLQ-C30 Global Health score, QoL improved in 16%/23%, worsened in 34%/39%, and remained stable in 50%/38% at 3 and 12 months, respectively. Median survival was 17.0 months (95% confidence interval [CI] 12.3-19.8 months). Higher baseline scores on both FACT-Hep and QLQ-C30 Global Health were associated with improved survival. Hazard ratios for death, per 10-unit decrease in QoL, were 0.90 (95% CI 0.83-0.98; P=.001) and 0.88 (95% CI 0.82-0.95; P=.001), respectively. Tumor size was inversely correlated with survival. Conclusions: Liver SBRT temporarily worsens appetite and fatigue, but not overall QoL. Stereotactic body radiation therapy is well tolerated and warrants

Besides a continuous increase of the worldwide use of electricity, the electric energy storage technology market is a growing sector. At the latest since the German energy transition ('Energiewende') was announced, technological solutions for the storage of renewable energy have been intensively studied. Storage technologies in various forms are commercially available. A widespread technology is the electrochemical cell. Here the cost per kWh, e. g. determined by energy density, production process and cycle life, is of main interest. Commonly, an electrochemical cell consists of an anode and a cathode that are separated by an ion permeable or ion conductive membrane - the separator - as one of the main components. Many applications use polymeric separators whose pores are filled with liquid electrolyte, providing high power densities. However, problems arise from different failure mechanisms during cell operation, which can affect the integrity and functionality of these separators. In the case of excessive heating or mechanical damage, the polymeric separators become an incalculable security risk. Furthermore, the growth of metallic dendrites between the electrodes leads to unwanted short circuits. In order to minimize these risks, temperature stable and non-flammable ceramic particles can be added, forming so-called composite separators. Full ceramic separators, in turn, are currently commercially used only for high-temperature operation systems, due to their comparably low ion conductivity at room temperature. However, as security and lifetime demands increase, these materials turn into focus also for future room temperature applications. Hence, growing research effort is being spent on the improvement of the ion conductivity of these ceramic solid electrolyte materials, acting as separator and electrolyte at the same time.

Low-power-laser therapy used in tendon damage
Strupinska, Ewa
1996-03-01
The following paper covers evaluation of low-power laser therapy results in chronic Achilles tendon damage and external Epicondylalia (tennis elbow). Fifty patients with Achilles damage (18 women and 32 men, age average 30, 24 plus or minus 10, 39 years) and fifty patients having external Epicondyalgiae (31 women and 19 men, age average 44, 36 plus or minus 10, 88 years) have been examined. The patients were irradiated by semiconductor infrared laser wavelength 904 nm separately or together with helium-neon laser wavelength 632.8 nm. The results of therapy have been based on the patient's interviews and examinations of patients as well as on the Laitinen pain questionnaire. The results prove analgesic effects in usage of low- power laser radiation therapy can be obtained.

It is not clear whether relaxation therapies are more or less effective than cognitive and behavioural therapies in the treatment of anxiety. The aims of the present study were to examine the effects of relaxation techniques compared to cognitive and behavioural therapies in reducing anxiety symptoms, and whether they have comparable efficacy across disorders. We conducted a meta-analysis of 50 studies (2801 patients) comparing relaxation training with cognitive and behavioural treatments of anxiety. The overall effect size (ES) across all anxiety outcomes, with only one combined ES in each study, was g = -0.27 [95% confidence interval (CI) = -0.41 to -0.13], favouring cognitive and behavioural therapies (number needed to treat = 6.61). However, no significant difference between relaxation and cognitive and behavioural therapies was found for generalized anxiety disorder, panic disorder, social anxiety disorder and specific phobias (considering social anxiety and specific phobias separately). Heterogeneity was moderate (I2 = 52; 95% CI = 33-65). The ES was significantly associated with age (p cognitive and/or behavioural therapy (p = 0.015), quality of intervention (p = 0.007), relaxation treatment format (p cognitive and behavioural therapies in the treatment of post-traumatic stress disorder, and obsessive-compulsive disorder and it might also be less effective at 1-year follow-up for panic, but there is no evidence that it is less effective for other anxiety disorders.

Kleinrath, H.
1977-01-01
This report analyses facts and their interpretations on nuclear-energy. Due to the fact that the discussion on nuclear energy was very controversial in the 1970s in Austria, there were various opinions. This report includes always two interpretations for each fact. Content overview: How high is the risk of the operation of nuclear-power-plants compared to other possibilities to produce electricity? How dangerous is the nuclear waste, which is produced during the operation of nuclear-power-plants? Which risks entail reprocessing-plants? How far is the question of final repository of nuclear waste solved? Is there any sense for Austria to do without nuclear-power-plants? Is electricity generated by nuclear power cheap? Are there alternatives in the generation of electricity to nuclear-power-plants? Does a waiver of nuclear-power-plants mean a social risk – hazard of our economic stability, hazard of jobs?

A membrane reactor has been studied for separating the hydrogen produced by the dissociation of hydroiodic acid in the thermochemical-sulfur iodine process. A dense metal membrane tube of wall thickness 0.250 mm has been considered in this analysis for hosting a fixed-bed catalyst: the selective separation of hydrogen from an azeotropic H{sub 2}O-HI mixture has been studied in the temperature range of 700-800 K. The materials being considered for the construction of the membrane tube are niobium and tantalum; as a matter of fact, the most commonly used Pd-Ag membranes cannot withstand the corrosive environment generated by the hydroiodic acid. The Damkohler-Peclet analysis has been used for designing the membrane reactor, while a finite element method has simulated its behaviour: the effect of the temperature and pressure on the HI conversion and hydrogen yield has been evaluated.

Wet separation processes as method to separate limestone and oil shale
Nurme, Martin; Karu, Veiko
2015-04-01
Biggest oil shale industry is located in Estonia. Oil shale usage is mainly for electricity generation, shale oil generation and cement production. All these processes need certain quality oil shale. Oil shale seam have interlayer limestone layers. To use oil shale in production, it is needed to separate oil shale and limestone. A key challenge is find separation process when we can get the best quality for all product types. In oil shale separation typically has been used heavy media separation process. There are tested also different types of separation processes before: wet separation, pneumatic separation. Now oil shale industry moves more to oil production and this needs innovation methods for separation to ensure fuel quality and the changes in quality. The pilot unit test with Allmineral ALLJIG have pointed out that the suitable new innovation way for oil shale separation can be wet separation with gravity, where material by pulsating water forming layers of grains according to their density and subsequently separates the heavy material (limestone) from the stratified material (oil shale)bed. Main aim of this research is to find the suitable separation process for oil shale, that the products have highest quality. The expected results can be used also for developing separation processes for phosphorite rock or all others, where traditional separation processes doesn't work property. This research is part of the study Sustainable and environmentally acceptable Oil shale mining No. 3.2.0501.11-0025 http://mi.ttu.ee/etp and the project B36 Extraction and processing of rock with selective methods - http://mi.ttu.ee/separation; http://mi.ttu.ee/miningwaste/

Multi-objective optimal power flow with FACTS devices
International Nuclear Information System (INIS)
Basu, M.
2011-01-01
This paper presents multi-objective differential evolution to optimize cost of generation, emission and active power transmission loss of flexible ac transmission systems (FACTS) device-equipped power systems. In the proposed approach, optimal power flow problem is formulated as a multi-objective optimization problem. FACTS devices considered include thyristor controlled series capacitor (TCSC) and thyristor controlled phase shifter (TCPS). The proposed approach has been examined and tested on the modified IEEE 30-bus and 57-bus test systems. The results obtained from the proposed approach have been compared with those obtained from nondominated sorting genetic algorithm-II, strength pareto evolutionary algorithm 2 and pareto differential evolution.

FACT. Flare alerts from blazar monitoring
Energy Technology Data Exchange (ETDEWEB)
Dorner, Daniela [Universitaet Wuerzburg (Germany); Bretz, Thomas [RWTH Aachen (Germany); Collaboration: FACT-Collaboration
2015-07-01
One of the major goals of the First G-APD Cherenkov Telescope is the longterm monitoring of bright TeV blazars. For more than three years, FACT has observed the blazars Mrk 421 and Mrk 501 and a few other sources on a regular basis. To understand these highly variable objects, simultaneous data at different wavelengths are very useful. FACT is not only taking part in multi-wavelength campaigns, but also sending alerts to other instruments in case of enhanced flux, to study flares within the multi-wavelength frame. To send fast alerts, an automatic quick look analysis was set up on site. Once the data are written on disk, they are automatically processed, and the analysis results are published on a website where other observers can monitor the activity of the source in the very high energy band. In addition, alerts are sent in case the flux is higher than a certain predefined value. In 2014, more than five alerts have been sent. Results from three years of monitoring are presented.

This folder contains twelve two-page leaflets (fact sheets) which answer questions posed about UK NIREX Ltd, its operations and radioactive waste. NIREX (the Nuclear Industry Radioactive Waste Executive) is the organisation responsible for implementing the British Government's policy for the disposal of most low- and intermediate-level radioactive waste produced in the United Kingdom. The questions posed are; what is NIREX. What is radioactivity. What is radioactive waste. Radioactive waste, what are the options. What is a radioactive waste repository. Some aspects of such a repository are then explained - how engineered barriers work, how geological barriers work, how long can concrete last, how is the radioactive waste transported, how are repository sites identified. The last two leaflets consider why do we need research, and look at radioactive waste management worldwide. The answers are in non-technical language and are short. (UK)

Separation of a light additive gas by separation nozzle cascades
International Nuclear Information System (INIS)
Becker, E.; Bley, P.; Ehrfeld, W.; Fritz, W.; Steinhaus, H.
1984-01-01
Double-turn separation nozzles, in comparison with single-turn separation nozzles, offer much greater advantages in the separation of UF6 and H2 than in the separation of the U isotopes, for which the double-turn separation nozzles were conceived. By using a double-turn separation-nozzle stage as a preseparation stage in combination with a low-temperature separator, one can reduce the ratio of the buffer input stream to the product stream, in contrast with the solution used up to this time, with only a slight increase in cost of about an order of magnitude. The control program in the case of return feeding of the UF6 from the buffer and the danger of production losses connected with it are thereby correspondingly diminished. An example is given of the enrichment of 235U using the title facility with UF6. (orig./PW)

Advances in Viral Vector-Based TRAIL Gene Therapy for Cancer
International Nuclear Information System (INIS)
Norian, Lyse A.; James, Britnie R.; Griffith, Thomas S.
2011-01-01
Numerous biologic approaches are being investigated as anti-cancer therapies in an attempt to induce tumor regression while circumventing the toxic side effects associated with standard chemo- or radiotherapies. Among these, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has shown particular promise in pre-clinical and early clinical trials, due to its preferential ability to induce apoptotic cell death in cancer cells and its minimal toxicity. One limitation of TRAIL use is the fact that many tumor types display an inherent resistance to TRAIL-induced apoptosis. To circumvent this problem, researchers have explored a number of strategies to optimize TRAIL delivery and to improve its efficacy via co-administration with other anti-cancer agents. In this review, we will focus on TRAIL-based gene therapy approaches for the treatment of malignancies. We will discuss the main viral vectors that are being used for TRAIL gene therapy and the strategies that are currently being attempted to improve the efficacy of TRAIL as an anti-cancer therapeutic

On the problems of separation work unit for the laser isotope separation
International Nuclear Information System (INIS)
Wang, Lijun
2008-01-01
The concept of separation power or separation work, which is widely used in Uranium isotope separation industry is introduced historically for the weak separating machine and so-called 'ideal cascade'. Therefore, when this concept is applied to a laser isotope separation facility, which is deeply different from a cascade in structure and in mechanism of separation, some confusions may occur. By comparison the costs of SWU of laser isotope separation facility and an ideal cascade we come to a conclusion: the concept of separation work is not applicable for laser isotope separation. In order to compare the economics of laser isotope separation technique with diffusion or centrifugation techniques an equivalent cost of SWU is suggested in this paper. (author)

Advanced therapies for the treatment of hemophilia: future perspectives.
Liras, Antonio; Segovia, Cristina; Gabán, Aline S
2012-12-13
Monogenic diseases are ideal candidates for treatment by the emerging advanced therapies, which are capable of correcting alterations in protein expression that result from genetic mutation. In hemophilia A and B such alterations affect the activity of coagulation factors VIII and IX, respectively, and are responsible for the development of the disease. Advanced therapies may involve the replacement of a deficient gene by a healthy gene so that it generates a certain functional, structural or transport protein (gene therapy); the incorporation of a full array of healthy genes and proteins through perfusion or transplantation of healthy cells (cell therapy); or tissue transplantation and formation of healthy organs (tissue engineering). For their part, induced pluripotent stem cells have recently been shown to also play a significant role in the fields of cell therapy and tissue engineering. Hemophilia is optimally suited for advanced therapies owing to the fact that, as a monogenic condition, it does not require very high expression levels of a coagulation factor to reach moderate disease status. As a result, significant progress has been possible with respect to these kinds of strategies, especially in the fields of gene therapy (by using viral and non-viral vectors) and cell therapy (by means of several types of target cells). Thus, although still considered a rare disorder, hemophilia is now recognized as a condition amenable to gene therapy, which can be administered in the form of lentiviral and adeno-associated vectors applied to adult stem cells, autologous fibroblasts, platelets and hematopoietic stem cells; by means of non-viral vectors; or through the repair of mutations by chimeric oligonucleotides. In hemophilia, cell therapy approaches have been based mainly on transplantation of healthy cells (adult stem cells or induced pluripotent cell-derived progenitor cells) in order to restore alterations in coagulation factor expression.

Health care organizations, both large and small, frequently undergo processes of change. In fact, if health care organizations are to improve over time, they must change; this includes pain services. The purpose of the present study was to examine a process of change in treatment model within a specialty interdisciplinary pain service in the UK. This change entailed a switch from traditional cognitive-behavioural therapy to a form of cognitive-behavioural therapy called acceptance and commitment therapy. An anonymous online survey, including qualitative and quantitative components, was carried out approximately 15 months after the initial introduction of the new treatment model and methods. Fourteen out of 16 current clinical staff responded to the survey. Three themes emerged in qualitative analyses: positive engagement in change; uncertainty and discomfort; and group cohesion versus discord. Quantitative results from closed questions showed a pattern of uncertainty about the superiority of one model over the other, combined with more positive views on progress reflected, and the experience of personal benefits, from adopting the new model. The psychological flexibility model, the model behind acceptance and commitment therapy, may clarify both processes in patient behaviour and processes of staff experience and skilful treatment delivery. This integration of processes on both sides of treatment delivery may be a strength of acceptance and commitment therapy.

Reactive power control of wind farm using facts devices
International Nuclear Information System (INIS)
Ashfaq, S.; Arif, A.; Shakeel, A.; Mahmood, T.
2014-01-01
Wind energy is an attainable option to complement other types of pollution-free green generation Grid connections of renewable energy resources are vital if they are to be effectively exploited, but grid connection brings problems of voltage fluctuation and harmonic distortion. FACTs devices are one of the power electronics revolutions to improve voltage profile, system stability, and reactive power control and to reduce transmission losses. The studied system here is a variable speed wind generation system based on Induction Generator (IG) with integration of different FACTs controllers in the wind farm. To harness the wind power efficiently the most reliable and expensive system in the present era is grid connected doubly fed induction generator. Induction generator with FACTs devices is a suitable economical replacement.

Financial Stylized Facts in the Word of Mouth Model
Misawa, Tadanobu; Watanabe, Kyoko; Shimokawa, Tetsuya
Recently, we proposed an agent-based model called the word of mouth model to analyze the influence of an information transmission process to price formation in financial markets. Especially, the short-term predictability of asset return was focused on and an explanation in the view of information transmission was provided to the question why the predictability was much clearly observed in the small-sized stocks. This paper, to extend the previous study, demonstrates that the word of mouth model also has a consistency with other important financial stylized facts. This strengthens the possibility that the information transmission among investors plays a crucial role in price formation. Concretely, this paper addresses two famous statistical features of returns; the leptokurtic distribution of return and the autocorrelation of return volatility. The reasons why these statistical facts receive especial attentions of researchers among financial stylized facts are their statistical robustness and practical importance, such as the applications to the derivative pricing problems.

Basic separative power of multi-component isotopes separation in a gas centrifuge
International Nuclear Information System (INIS)
Jiang, Hongmin; Lei, Zengguang; Zhuge, Fu
2008-01-01
On condition that the overall separation factor per unit exists in centrifuge for multi-component isotopes separation, the relations between separative power of each component and molecular weight have been investigated in the paper while the value function and the separative power of binary-component separation are adopted. The separative power of each component is proportional to the square of the molecular weight difference between its molecular weight and the average molecular weight of other remnant components. In addition, these relations are independent on the number of the components and feed concentrations. The basic separative power and related expressions, suggested in the paper, can be used for estimating the separative power of each component and analyzing the separation characteristics. The most valuable application of the basic separative power is to evaluate the separative capacity of centrifuge for multi-component isotopes. (author)

The Contingent Unknowability of Facts and its Relation with Informal, Epistemological Contexts
Directory of Open Access Journals (Sweden)
Stanley Kreiter Bezerra Medeiros
2017-11-01
Full Text Available This paper focuses on elements that are involved in a specific type of judgment, namely, those involving facts that, in virtue of contingent reasons, are out of our epistemic reach. Its goal is to propose a philosophical explanation about why we, in informal contexts, take some facts as contingently unknowable. In order to accomplish that goal, we develop a theory that defines contingently unknowable facts in a very specific way. We establish three clauses that are jointly necessary and sufficient — so we argue — for taking an arbitrary fact as contingently unknowable. In a variety of contexts, this strategy has the potential of reducing efforts in an epistemological analysis of this particular type of unknowability.

Five analogies between a King's Speech treatment and contemporary play therapies.
Terr, Lenore C
2012-01-01
Psychiatric patients frequently respond positively to play therapy, which may rely on psychoanalytic, Jungian, cognitive-behavioral, familial, school-based, or other theories. I wished to determine if there were unifying principles that tie together these various types of play treatments. The fact-based film, The King's Speech, vividly illustrates play utilized by Lionel Logue in his speech treatment (1926-1939) of the future King of England. In the film I found five analogies to the play therapy I employ in office practice. The play scenes in The King's Speech point to five unifying principles among contemporary play therapies: (1) the crucial nature of the relationship, (2) the centrality of having fun, (3) the occasional reliance on others, (4) the interjection of pithy talk, and (5) the usefulness of a little drama. No matter what theory a play therapist ascribes to, these five unifying principles should be kept in mind during treatment.

E-therapy: practical, ethical, and legal issues.
Manhal-Baugus, M
2001-10-01
E-therapy is a term that has been coined to describe the process of interacting with a therapist online in ongoing conversations over time when the client and counselor are in separate or remote locations and utilize electronic means to communicate with each other. It is a relatively new modality of assisting individuals resolve life and relationship issues. E-therapy utilizes the power and convenience of the internet to allow simultaneous (synchronous) and time-delayed (asynchronous) communication between an individual and a professional. For the purposes of this paper, e-therapy is defined as a licensed mental health care professional providing mental health services via e-mail, video conferencing, virtual reality technology, chat technology, or any combination of these. It does not include self-help methods such as public bulletin boards or private listservs. E-therapy is not psychotherapy or psychological counseling per se since it does to presume to diagnose or treat mental or medical disorders. However, e-therapy is flexible enough to also address many difficulties which clients present to the online therapist. As in other types of therapy, such as bibliotherapy, occupational therapy, and rehabilitation therapy), e-therapy does assist a person in addressing specific concerns with specific skills. This article examines the following issues of e-therapy. First, the types of e-therapy and related services are described to provide a background for the article. Second, the ethical codes which have been adopted by three major professional organizations (American Counseling Association, National Board for Certified Counselors, and the International Society for Mental Health Online) pertaining to e-therapy are summarized for professional and consumer use. Finally, the practical, ethical, and legal issues of e-therapy services are discussed fully.

Composite separators and redox flow batteries based on porous separators
Li, Bin; Wei, Xiaoliang; Luo, Qingtao; Nie, Zimin; Wang, Wei; Sprenkle, Vincent L.
2016-01-12
Composite separators having a porous structure and including acid-stable, hydrophilic, inorganic particles enmeshed in a substantially fully fluorinated polyolefin matrix can be utilized in a number of applications. The inorganic particles can provide hydrophilic characteristics. The pores of the separator result in good selectivity and electrical conductivity. The fluorinated polymeric backbone can result in high chemical stability. Accordingly, one application of the composite separators is in redox flow batteries as low cost membranes. In such applications, the composite separator can also enable additional property-enhancing features compared to ion-exchange membranes. For example, simple capacity control can be achieved through hydraulic pressure by balancing the volumes of electrolyte on each side of the separator. While a porous separator can also allow for volume and pressure regulation, in RFBs that utilize corrosive and/or oxidizing compounds, the composite separators described herein are preferable for their robustness in the presence of such compounds.

Modern role and issues of radiation therapy for benign diseases
International Nuclear Information System (INIS)
Miyashita, Tsuguhiro; Tateno, Atsushi; Kumazaki, Tatsuo
1999-01-01
Cases of radiation therapy for benign diseases have diminished in number because of recent alternative methods and knowledge about radiation carcinogenesis. In contrast to this tendency, our cases of benign diseases have recently increased. The facts made us reconsider today's radiation therapy of benign diseases. We reviewed 349 patients who were diagnosed as having benign tumors or non-neoplastic conditions and treated by radiation therapy in the past sixteen years. Analyzed items were the annual transition of treatment number, sorts of diseases, patients' age and sex, and the goal of therapy. Of all radiation therapy patients, benign diseases account for 9.26%. The annual percentages were 0.5%, 6.0%, 11.2% and 13.7% at intervals of five years since 1982. The majority was 246 post-operative irradiation for keloids (71%) and 41 pituitary adenomas (12%). Compared with malignant tumors, benign disease patients were statistically younger and female-dominant. Applications of radiation therapy in keloids and pituitary adenomas had definite goals, but were unclear in other rare diseases. Benign diseases should be treated by radiation therapy as the second or third option, provided the patients have serious symptoms and their diseases do not respond to other modalities. It seems to be widely accepted that favorite cases such as keloids and pituitary adenomas are treated by radiation therapy. But, optimal radiation therapies for other rare benign diseases have not been established. Therefore, the building of databases on radiation therapy on benign diseases should be pursued. Since benign disease patients were young and female-dominant and had many remaining years, their carcinogenicity potential should be considered. (author)

Harnessing electro driven separation technique for the separation of selected agrochemicals
International Nuclear Information System (INIS)
Wan Aini Wan Ibrahim; Alam, S.M. Monjurul; Azli Sulaiman
2008-01-01
Electro driven separation techniques offer a different approach to the analysis of complex mixtures than do traditional pressure-driven chromatographic system; it may rely on electrophoresis, the transport of charged species through a medium by an applied field or may rely on electro driven mobile phase to provide a true chromatographic separation. In the current work the potential of an electro driven separation technique viz. Micellar electrokinetic chromatography (MEKC), is harnessed for the separation of selected agrochemicals (organophosphorus pesticides, OPPs) widely used in the agriculture sector in Malaysia. The current study compares the use of MEKC in normal mode (NM) and reverse mode (RM) for the separation of the selected OPPS. This study also highlights the difference in separations produced by performing separations in normal mode-MEKC (NM-MEKC) and reverse mode-MEKC (RM-MEKC) for the selected OPPs. In RM-MEKC, separation is conducted at acidic pH (pH 2.5 in the current work) where the electro osmotic flow (EOF) is weak whereas in NM-MEKC, the separation is carried out under basic pH (9.3 in this work) where the EOF is strong. A reverse migration order of the OPPs was observed under RM-MEKC. Separation under NM-MEKC was found to be superior to those of RM- MEKC. A comparison is also made between separations performed under sweeping-NM-MEKC and sweeping-RM-MEKC. In sweeping, the OPPs are prepared in the same background solution (BGS) minus the micelles and is adjusted to the same conductivity as the BGS. The study showed that NM-MEKC is more sensitive than RM-MEKC but sweeping-RM-MEKC is superior to sweeping-NM-MEKC. However, sweeping-RM-MEKC only separates two of the OPPs in a single run whereas sweeping-NM-MEKC separates four OPPs in a single run. The better choice of separation mode would be sweeping-NM- MEKC for more OPPs separation in a single run. (author)

Full Text Available In dissolving microneedle (DMN-mediated therapy, complete and rapid delivery of DMNs is critical for the desired efficacy. Traditional patch-based DMN delivery, however, may fail due to incomplete delivery from insufficient skin insertion or rapid separation of microneedles due to their strong bond to the backing film. Here, we introduce the Troy microneedle, which was created by cyclic contact and drying on the pillar (CCDP, and which enabled simultaneous complete and rapid delivery of DMN. This CCDP process could be flexibly repeated to achieve a specific desired drug dose in a DMN. We evaluated DMN separation using agarose gel, and the Troy microneedle achieved more complete and rapid separation than other, more deeply dipped DMN, primarily because of the Troy's minimal junction between the DMN and pillar. When Troy microneedles were applied to pig cadaver skin, it took only 15 s for over 90% of encapsulated rhodamine B to be delivered, compared to 2 h with application of a traditional DMN patch. In vivo skin penetration studies demonstrated rapid DMN-separation of Troy microneedles still in solid form before dissolution. The Troy microneedle overcomes critical issues associated with the low penetration efficiency of flat patch-based DMN and provides an innovative route for DMN-mediated therapy, combining patient convenience with the desire drug efficacy.

Transplantation: fantasy, fiction and fact.
Magee, Reginald
2004-03-01
Today organ transplantation is considered a routine surgical procedure. The idea of transferring tissues from one person to another has been inspiring to the minds of artists depicting the Saints Cosmos and Damian and also writers such as Mary Shelley. Early attempts at tissue transplantation were unsuccessful but in the last 50 years medical research has brought it into reality. The present paper looks at the subject from the realms of fantasy through the works of fiction and finally into everyday fact.

Technical feasibility of advanced separation; Faisabilite technique de la separation poussee
Energy Technology Data Exchange (ETDEWEB)
Rostaing, Ch
2004-07-01
Advanced separation aims at reducing the amount and toxicity of high-level and long lived radioactive wastes. The Purex process has been retained as a reference way for the recovery of the most radio-toxic elements: neptunium, technetium and iodine. Complementary solvent extraction processes have to be developed for the separation of americium, curium and cesium from the high activity effluent of the spent fuel reprocessing treatment. Researches have been carried out with the aim of demonstrating the scientifical and technical feasibility of advanced separation of minor actinides and long lived fission products from spent fuels. The scientifical feasibility was demonstrated at the end of 2001. The technical feasibility works started in the beginning of 2002. Many results have been obtained which are presented and summarized in this document: approach followed, processes retained for the technical feasibility (An/Ln and Am/Cm separation), processes retained for further validation at the new shielded Purex installation, technical feasibility of Purex adaptation to Np separation, technical feasibility of Diamex (first step: (An+Ln)/other fission products) separation), technical feasibility of Sanex process (second step: An(III)/Ln(III) separation), technical feasibility of Am(III)/Cm(III) separation, cesium separation, iodine separation, technical-economical evaluation, conclusions and perspectives, facilities and apparatuses used for the experiments.

An agent-based approach to financial stylized facts
Shimokawa, Tetsuya; Suzuki, Kyoko; Misawa, Tadanobu
2007-06-01
An important challenge of the financial theory in recent years is to construct more sophisticated models which have consistencies with as many financial stylized facts that cannot be explained by traditional models. Recently, psychological studies on decision making under uncertainty which originate in Kahneman and Tversky's research attract a lot of interest as key factors which figure out the financial stylized facts. These psychological results have been applied to the theory of investor's decision making and financial equilibrium modeling. This paper, following these behavioral financial studies, would like to propose an agent-based equilibrium model with prospect theoretical features of investors. Our goal is to point out a possibility that loss-averse feature of investors explains vast number of financial stylized facts and plays a crucial role in price formations of financial markets. Price process which is endogenously generated through our model has consistencies with, not only the equity premium puzzle and the volatility puzzle, but great kurtosis, asymmetry of return distribution, auto-correlation of return volatility, cross-correlation between return volatility and trading volume. Moreover, by using agent-based simulations, the paper also provides a rigorous explanation from the viewpoint of a lack of market liquidity to the size effect, which means that small-sized stocks enjoy excess returns compared to large-sized stocks.

Full Text Available In the oil exploitation, produced fluids are composed of oil, gas, water and sand (depending on the reservoir location. The presence of sand in flow oil leads to several industrial problems for example: erosion and accumulation in valves and pipeline. Thus, it is necessary to stop production for manual cleaning of equipments and pipes. These facts have attracted attention of academic and industrial areas, enabling the appearing of new technologies or improvement of the water/oil/sand separation process. One equipment that has been used to promote phase separation is the hydrocyclone due to high performance of separation and required low cost to installation and maintenance. In this sense, the purpose of this work is to study numerically the effect of geometric parameters (vortex finder diameter of the hydrocyclone and sand concentration on the inlet fluid separation process. A numerical solution of the governing equations was obtained by the ANSYS CFX-11 commercial code. Results of the streamlines, pressure drop and separation efficiency on the hydrocyclone are presented and analyzed. It was observed that the particles concentration and geometry affect the separation efficiency of the hydrocyclone.

Pseudo-stationary separation materials for highly parallel separations.
Energy Technology Data Exchange (ETDEWEB)
Singh, Anup K.; Palmer, Christopher (University of Montana, Missoula, MT)
2005-05-01
Goal of this study was to develop and characterize novel polymeric materials as pseudostationary phases in electrokinetic chromatography. Fundamental studies have characterized the chromatographic selectivity of the materials as a function of chemical structure and molecular conformation. The selectivities of the polymers has been studied extensively, resulting in a large body of fundamental knowledge regarding the performance and selectivity of polymeric pseudostationary phases. Two polymers have also been used for amino acid and peptide separations, and with laser induced fluorescence detection. The polymers performed well for the separation of derivatized amino acids, and provided some significant differences in selectivity relative to a commonly used micellar pseudostationary phase. The polymers did not perform well for peptide separations. The polymers were compatible with laser induced fluorescence detection, indicating that they should also be compatible with chip-based separations.

Have complementary therapies demonstrated effectiveness in rheumatoid arthritis?
Fernández-Llanio Comella, Nagore; Fernández Matilla, Meritxell; Castellano Cuesta, Juan Antonio
2016-01-01
In recent decades the treatment of rheumatoid arthritis (RA) has improved thanks to the use of highly effective drugs. However, patients usually require long term therapy, which is not free of side effects. Therefore RA patients often demand complementary medicine, they seek additional sources of relief and/or less side effects. In fact 30-60% of rheumatic patients use some form of complementary medicine. Therefore, from conventional medicine, if we want to optimally treat our patients facilitating communication with them we must know the most commonly used complementary medicines. The aim of this review is to assess, based on published scientific research, what complementary therapies commonly used by patients with RA are effective and safe.

Brill, A.B.; Adelstein, S.J.; Saenger, E.L.; Webster, E.W.
1982-01-01
Low Level Raidation Effects: A Fact Book, prepared by the Society of Nuclear Medicine Subcommittee on the Risks of Low-Level Ionizing Radiation, attempts to examine the health effects of small doses of radiation. For immediate questions, this work provides a well-organized brief summary of recent radiologic data from refereed scientific literature and from the publications of advisory groups such as the National Council of Radiation Protection and Measurement (NCRP), the International Commission on Radiological Protection (ICRP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and the National Academy of Sciences (NAS). Since it consists almost entirely of tables and graphs from the above-mentioned sources along with summary paragraphs, the Fact Book is very useful in the preparation of lectures. The book is divided into seven sections. Chapter One, Glossary, Units and Conversion Factors, is useful because nearly all data given in the rest of the book is in conventional units and should be converted to SI units for future technical audiences. Chapter 2, Radiobiology, covers the fundamental principles of the field. Chapter 3, Radiation Doses, can be used to help an audience appreciate the relative magnitudes of radiation exposures they may read about or encounter. Chapter 4, Late Somatic Effects of Low Doses of Ionizing Radiation, gives data concerning cancer induction and embryonic effects, and Chapter 5 provides data on genetic effects Chapter 6, Risks, Statistical Facts and Public Perception can be used to compare the risks of radiation exposure with more commonly encountered risks

A centrifugal gas separator of a highly endurable construction and with improved gas sealing qualities utilizes a cylincrical elastic bellows or similar system in cooperation with a system of dynamic pressure operable gas seals as means for removing separated gases from the interior of the rotor drum, collecting the separated gases in their respective separated gas chambers defined by the corresponding bellows and their supporting stationary wall members, gas seals and rotor end caps, and means for discharging to the exterior of the surrounding cylindrical wall member the gaseous components from their respective separated gas chambers. In the vicinity of the rotary drum motor is a mixed gas chamber and means for providing the gas mixture along a co-axial passage into the rotary drum chamber. Orifices are bored into the end caps of the rotary drum to direct the separated gases into the aforementioned separated gas chambers which, through the action of the gas seals, freely slide upon the rotating drum to collect and thereafter discharge the thus separated gases. Therefore, according to the present invention, helium gas used to prevent separated gas remixture is unnecessary and, furthermore, the gas seals and elastic bellows means provide an air-tight seal superior to that of the contact sealing system of the former art.

Recent developments in separation of low molecular weight heparin anticoagulants.
Sadowski, Radosław; Gadzała-Kopciuch, Renata; Buszewski, Bogusław
2017-10-05
The general function of anticoagulants is to prevent blood clotting and growing of the existing clots in blood vessels. In recent years, there has been a significant improvement in developing methods of prevention as well as pharmacologic and surgical treatment of thrombosis. For over the last two decades, low molecular weight heparins (LMWHs) have found their application in the antithrombotic diseases treatment. These types of drugs are widely used in clinical therapy. Despite the biological and medical importance of LMWHs, they have not been completely characterized in terms of their chemical structure. Due to both, the structural complexity of these anticoagulants and the presence of impurities, their structural characterization requires the employment of advanced analytical techniques. Since separation techniques play the key role in these endeavors, this review will focus on the presentation of recent developments in the separation of LMWH anticoagulants.

The seeds as biological objects that possess the complicated microstructure are very difficult to be exanimated by x-ray technology. The application of x-rays and further elaboration of optical separators, principle of action, basic specifications, way of their use and their efficiency was shown in the article. The x-ray separator may distinguish all hidden seed defects as it was described by a programmer, where owing to the use of the optical separating block in visual range it is possible to add some more details as a shape, brightness and a color of object surface being exanimated. The elaboration of such separation equipment is scientifically hard work requiring time and expenses. Last year researchers of ‘LETI’ developed the working model of industrial x-ray separator for examination of grains and nuts in different crops. This model was made on the basis of photoseparator F-5 manufactured at OAO ‘Voronezhselmash’. The instrument state and its mechanism operation are highlighted on monitor. In the regime of processing (separation and examination of each controlled batch, the passport is produced with following information on identification code, time of material receiving, time of test passed, number of grains or seeds tested. The code of receiver of material is given to each of established characteristics when working the regime of separation, determination of number of objects with characteristics tested and number of unidentified objects. The application of x-ray separators constructed on the basis of photoseparator F-5 enables to carry out the complex estimation on seed quality and separation in only instrument with the development of electronic protocol with many characteristics.

FACT. Influence of night sky background photons and crosstalk

During the last four years, the First G-APD Cherenkov Telescope (FACT) established silicon-based photo detectors as a valid concept for the imaging atmospheric Cherenkov technique. These detectors, namely silicon photo multipliers (SiPMs), are more robust to bright light conditions than conventional photo multiplier tubes (PMTs). At the same time, SiPMs feature a high photon detection efficiency. As a consequence, this technology yields observations at bright light conditions where PMTs would be damaged. However, dark counts and night sky background light (NSB), in combination with optical crosstalk and after-pulses contribute to the extracted signal from Cherenkov photons. Therefore, they cause a bias on the photon charge extraction and any subsequent analysis steps. Consequently, it is necessary to understand their impact on the data of FACT. This presentation will show the influence of changing NSB and crosstalk conditions on the performance of FACT. Therefore, the influence on the analysis chain is investigated on basis of data that were taken at different NSB conditions as well as dedicated Monte Carlo simulations.

Purpose: Prospectively evaluate the quality of life (QOL) of patients with NSCLC participating in a randomized phase III study conducted by the RTOG and Eastern Cooperative Oncology Group. Determine the factors which influence QOL during and post therapy. Materials and Methods: From (4(90)) to (4(94)) to 75 patients (pts) were randomized on RTOG 89-01 between a regimen containing radiation therapy (RT) versus a regimen containing surgery (S). All pts received induction vinblastine and cisplatin, followed by either S or RT and consolidation chemotherapy (CT). Pts were given the self-assessment QOL forms prior to the start of therapy, post induction CT, post RT or S, and periodically during follow-up. Two questionnaires were used: Functional Assessment of Cancer Therapy for lung cancer patients (FACT-L) and Functional Living Index-Cancer (FLIC). The FACT-L consists of 44 questions covering 6 domains (physical, social, and emotional well-being, relationship with physician, fulfilment, and lung cancer specific concerns), FLIC contains 22 questions summing to one total score. Results: 51 pts participated in the QOL endpoint, 24 were excluded: 3 pts refused, institution did not administer QOL questionnaires in 9 pts, 3 completed QOL after start of therapy, 1 institution refused to participate, 5 questionnaires were incomplete/unusable, 1 pt could not read English, and 2 were ineligible for treatment. Participation in QOL was not predicted by any pretreatment characteristic. Women had worse pretreatment QOL (p<0.005, by FLIC) and more problems with disease-related symptoms (p<0.005, by FACT) than men. Pts with KPS 90-100 had better pretreatment QOL than pts with KPS 60-80 (p<0.025, FLIC). Neither race, marital status, education level, age, prior weight loss, nor disease symptoms statistically significantly influenced pretreatment QOL. Initial QOL did not predict overall survival. FACT-L was reported on 25 pts post induction CT. Follow-up FACT-L was available on 12 pts

Full Text Available The proposed procedure is based on the fact that total transformer losses (PLL1,n, determined by short circuit test, can be separated into two components: the eddy current losses in the windings (PEC1,n and stray flux losses (PSL1,n in iron parts of construction as well as in the transformer tank walls. The total additional load losses, PLLd1 and PLLdh, are determined by short circuit test results, conducted at rated frequency (f1 and at increased harmonic frequency (fh=h*f1. Using so obtained total additional load losses, PLLd1 and PLLdh, which can be expressed in the form PLLdh=PEC1,n*h2 + PSL1,n*h, the corresponding rate additional load losses values PEC1,n and PSL1,n are derived. At the end, for given load with predefined high harmonics content, (Ih/I1n, relative to rated current, the total additional load losses value ΣPLLdh > PLLd1, is found. In such a way all harmonics up to hmax are taken into account.

Bacterial separation from human blood samples can help with the identification of pathogenic bacteria for sepsis diagnosis. In this work, we report an acoustofluidic device for label-free bacterial separation from human blood samples. In particular, we exploit the acoustic radiation force generated from a tilted-angle standing surface acoustic wave (taSSAW) field to separate Escherichia coli from human blood cells based on their size difference. Flow cytometry analysis of the E. coli separated from red blood cells shows a purity of more than 96%. Moreover, the label-free electrochemical detection of the separated E. coli displays reduced non-specific signals due to the removal of blood cells. Our acoustofluidic bacterial separation platform has advantages such as label-free separation, high biocompatibility, flexibility, low cost, miniaturization, automation, and ease of in-line integration. The platform can be incorporated with an on-chip sensor to realize a point-of-care sepsis diagnostic device. (paper)

This invention relates to molecular and atomic isotope separation and is particularly applicable to the separation of 235 U from other uranium isotopes including 238 U. In the method described a desired isotope is separated mechanically from an atomic or molecular beam formed from an isotope mixture utilising the isotropic recoil momenta resulting from selective excitation of the desired isotope species by radiation, followed by ionization or dissociation by radiation or electron attachment. By forming a matrix of UF 6 molecules in HBr molecules so as to collapse the V 3 vibrational mode of the UF 6 molecule the 235 UF 6 molecules are selectively excited to promote reduction of UF 6 molecules containing 235 U and facilitate separation.

Full Text Available It is now a universally acknowledged fact that maggot therapy can be used successfully to treat chronic, long-standing, infected wounds, which have previously failed to respond to conventional treatment. Such wounds are typically characterized by the presence of necrotic tissue, underlying infection and poor healing. Maggot therapy employs the use of freshly emerged, sterile larvae of the common green-bottle fly, Phaenicia (Lucilia sericata, and is a form of artificially induced myiasis in a controlled clinical situation. In this review article, we will discuss the role of maggots and their preparation for clinical use. Maggot therapy has the following three core beneficial effects on a wound: debridement, disinfection and enhanced healing. In part I we explore our current understanding of the mechanisms underlying these effects.
