    Roche, Eric


    The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

  2. Therapeutic boundaries in telepsychology: Unique issues and best practice recommendations. (United States)

    Drum, Katherine B; Littleton, Heather L


    Technology-assisted mental health services are becoming much more routinely utilized by clients and practitioners alike. Clinicians practicing telepsychology must prepare themselves in order to provide competent care in this ever-evolving context of service delivery. Although much has been written with regards to considerations of ethical and legal practice, practical and logistical guidelines, and the advantages and disadvantages of the delivery of services via the use of technology, little to no attention has been paid to issues related to therapeutic boundaries in the telepsychology relationship. Clinicians must consider how to maintain appropriate boundaries in telepsychology settings in order to prevent harm and optimize treatment gains. Such considerations are also necessary given that it is probable that the telepsychology clinician will encounter novel boundary issues that are unlikely to occur in the traditional face-to-face therapy setting. We discuss the clinical utility of boundaries, potential boundary issues in telepsychology settings, and suggested best practice recommendations to ensure competent, ethical, and efficacious treatment in this novel context of service delivery.

  3. Imaging Multidimensional Therapeutically Relevant Circadian Relationships

    Directory of Open Access Journals (Sweden)

    Jamil Singletary


    Full Text Available Circadian clocks gate cellular proliferation and, thereby, therapeutically target availability within proliferative pathways. This temporal coordination occurs within both cancerous and noncancerous proliferating tissues. The timing within the circadian cycle of the administration of drugs targeting proliferative pathways necessarily impacts the amount of damage done to proliferating tissues and cancers. Concurrently measuring target levels and associated key pathway components in normal and malignant tissues around the circadian clock provides a path toward a fuller understanding of the temporal relationships among the physiologic processes governing the therapeutic index of antiproliferative anticancer therapies. The temporal ordering among these relationships, paramount to determining causation, is less well understood using two- or three-dimensional representations. We have created multidimensional multimedia depictions of the temporal unfolding of putatively causative and the resultant therapeutic effects of a drug that specifically targets these ordered processes at specific times of the day. The systems and methods used to create these depictions are provided, as well as three example supplementary movies.

  4. Identification of unique expression signatures and therapeutic targets in esophageal squamous cell carcinoma

    Full Text Available Abstract Background Esophageal squamous cell carcinoma (ESCC, the predominant histological subtype of esophageal cancer, is characterized by high mortality. Previous work identified important mRNA expression differences between normal and tumor cells; however, to date there are limited ex vivo studies examining expression changes occurring during normal esophageal squamous cell differentiation versus those associated with tumorigenesis. In this study, we used a unique tissue microdissection strategy and microarrays to measure gene expression profiles associated with cell differentiation versus tumorigenesis in twelve cases of patient-matched normal basal squamous epithelial cells (NB, normal differentiated squamous epithelium (ND, and squamous cell cancer. Class comparison and pathway analysis were used to compare NB versus tumor in a search for unique therapeutic targets. Results As a first step towards this goal, gene expression profiles and pathways were evaluated. Overall, ND expression patterns were markedly different from NB and tumor; whereas, tumor and NB were more closely related. Tumor showed a general decrease in differentially expressed genes relative to NB as opposed to ND that exhibited the opposite trend. FSH and IgG networks were most highly dysregulated in normal differentiation and tumorigenesis, respectively. DNA repair pathways were generally elevated in NB and tumor relative to ND indicating involvement in both normal and pathological growth. PDGF signaling pathway and 12 individual genes unique to the tumor/NB comparison were identified as therapeutic targets, and 10 associated ESCC gene-drug pairs were identified. We further examined the protein expression level and the distribution patterns of four genes: ODC1, POSTN, ASPA and IGF2BP3. Ultimately, three genes (ODC1, POSTN, ASPA were verified to be dysregulated in the same pattern at both the mRNA and protein levels. Conclusions These data reveal insight into genes and

  5. The dynamics of empirically derived factors in the therapeutic relationship. (United States)

    Nuetzel, Eric J; Larsen, Randy J; Prizmic, Zvjezdana


    The therapeutic relationship is the source of major concepts in psychoanalytic clinical theory. Such concepts as resistance, transference, countertransference, and the alliance are fundamental, even though there may be shifts in meaning between theoretical schools and clinical contexts. In the clinical psychoanalytic literature, disagreement exists over the nature of the alliance and its essential components. Empirical studies using reliable patient, therapist, and observer scales to assess the alliance demonstrate a correlation with psychotherapeutic gains. In the study reported here, thirteen patients were followed for 6 to 33 months of psychodynamic psychotherapy, during which time their views of the therapeutic relationship were assessed, and several experiential measures taken, all on a weekly basis. Statistical analyses reveal that the therapeutic relationship, as reflected in the patients' weekly responses to the St. Louis Therapeutic Relationship Rating Scale, has four distinct components: therapeutic alliance, resistance, transference love, and negative transference. On a week-by-week basis, the therapeutic alliance was the strongest predictor of improvement in patient-reported general adjustment, as reflected in such areas as self-esteem, positive affect, social relations, work productivity, satisfaction, and optimism. Time plots of the variables show the typical time course for the components of the therapeutic relationship, as well as for improvement on the experiential variables. Results indicate that the therapeutic alliance, transference, and resistance are central components of the psychotherapeutic relationship, which in turn predict the ongoing life experience of the patient.

  6. Investigating Supervisory Relationships and Therapeutic Alliances Using Structural Equation Modeling (United States)

    DePue, Mary Kristina; Lambie, Glenn W.; Liu, Ren; Gonzalez, Jessica


    The authors used structural equation modeling to examine the contribution of supervisees' supervisory relationship levels to therapeutic alliance (TA) scores with their clients in practicum. Results showed that supervisory relationship scores positively contributed to the TA. Client and counselor ratings of the TA also differed.

    Full Text Available This article describes a qualitative study of helpful aspects of the therapeutic relationship in Integrative Psychotherapy. Participants of the study were sixteen clients who were in the process of Integrative Psychotherapy for at least a year. Participants were interviewed with the adapted version of the Change Interview (Elliott, 1999, which involves a semi-structured empathic exploration of the client's experience in therapy. The analysis of the clients’ experience of Integrative Psychotherapy revealed six categories of helpful aspects of therapeutic relationship: the therapist’s empathic attunement, the therapist’s acceptance, the match between the client and the therapist, feelings of trust and safety, feeling of connection, and experience of a new relational experience. Based on results of the research, we developed a model of the healing relationship in integrative psychotherapy. This model describes the interrelatedness of these six helpful aspects of the therapeutic relationship. The categories of empathic attunement and acceptance proved to be the most important categories relating to the therapist’s contribution to the healing therapeutic relationship. Clients described that the therapist’s empathic attunement and acceptance influenced the development of safety and trust, feelings of connection and promotion of new relational experiences. The results of this study are discussed in relation to the theories of Integrative Psychotherapy and research regarding the therapeutic relationship in psychotherapy.

  8. The intercultural and interracial therapeutic relationship: challenges and recommendations. (United States)

    Qureshi, Adil; Collazos, Francisco


    Although research has demonstrated that mental health services function with patients from different cultural backgrounds, a variety of culture- and race-related factors can result in services being of lower quality than that which occurs when the clinician and patient are from the same culture. The provision of culturally competent care requires many institutional and organizational adaptations that lie beyond the control of most mental health professionals. The therapeutic relationship, however, remains a key factor of mental healthcare that can be attended to by individual therapists. The therapeutic relationship plays an important role in almost every therapeutic approach, and has been increasingly recognized as representing a means to the provision of quality intercultural and interracial treatment. At the same time, a host of cultural and racial factors relating to both the patient and clinician can compromise the development of the therapeutic relationship. This paper will explore some of the key issues that complicate therapeutic contact and communication, and will outline means by which to strengthen key components of the therapeutic relationship.

  10. Theoretical frameworks for understanding and investigating the therapeutic relationship in psychiatry. (United States)

    McGuire, R; McCabe, R; Priebe, S


    Mental health care is delivered through a relationship between a clinician and a patient. Although this therapeutic relationship is of central importance for mental health care, it appears to be relatively neglected in psychiatric research. Empirical research has for the most part adopted concepts and methods developed in psychotherapy and general medical practice. Hence, unpacking the presuppositions that have informed research on the therapeutic relationship to date may be a useful first step in developing this field. A review of the literature was carried out. Six central theories are identified as framing the definitions and methods on this topic: role theory, psychoanalysis, social constructionism, systems theory, social psychology and cognitive behaviourism. To date, role theory, psychoanalysis and systems theory appear to be the frameworks most often applied in research in this field. Each perspective offers a unique emphasis in the analysis of the therapeutic relationship, which is reflected in the empirical work from each perspective discussed herein. None of the theories identified have been fully specified and comprehensively investigated in psychiatric settings. However, more than one approach may be used for thinking about relationships, depending on the treatment situation. Further specification and testing of the theories in psychiatric practice--taking account of the specific context--is warranted to underpin more pragmatic research. A stronger link between fundamental psychological and sociological research and applied health care research would advance our understanding of which elements of positive therapeutic relationships are instrumental in improving patient outcome and ultimately contribute to improving mental health care.

  11. Transitional discharge based on therapeutic relationships: state of the art. (United States)

    Forchuk, Cheryl; Reynolds, William; Sharkey, Siobhan; Martin, Mary-Lou; Jensen, Elsabeth


    The Transitional Discharge Model (TDM) has been used to facilitate effective discharge from psychiatric hospital to community. A summary of the research to date on TDM is given. The model is based on the provision of therapeutic relationships to provide a safety net throughout the discharge and community reintegration processes. These relationships include both staff and peer involvement; hospital inpatient staff continue to remain involved with the client until a therapeutic relationship is established with a community care provider, and peer support is offered from a former consumer of mental health services who is currently living in the community. Studies found that the TDM facilitates increased discharge rates, lower readmission rates, and cost savings--making it a collaborative, cost-effective method of providing quality patient care and positive health care outcomes. The TDM Plan of Research is presented and reflects the collaboration between stakeholders and the integration of consumer advocacy, clinical practice, education, policy, and research in various countries.

  12. Developing effective therapeutic relationships with children, young people and their families. (United States)

    Roberts, Jane; Fenton, Gaynor; Barnard, Michaela


    It is imperative that nurses caring for children, young people and their families develop and maintain effective, trusting and collaborative therapeutic relationships that sit within the scope of professional boundaries. This relationship is the nurse's responsibility and should be positive and mutually acceptable to all stakeholders. A unique challenge for children's nurses is to address and prioritise the child's care needs, while meeting the needs of, and empowering, the family. The 6Cs--care, compassion, competence, communication, courage, commitment--should underpin care and enable nurses to overcome challenges such as time pressures, acute situations or disturbed family expectation. Confidentiality and safeguarding should always be observed.

  13. Examining the Therapeutic Relationship and Confronting Resistances in Psychodynamic Psychotherapy (United States)

    Gentile, Julie P.; Gillig, Paulette Marie


    Psychodynamic psychotherapy is effective for a variety of mental health symptoms. This form of psychotherapy uses patient self reflection and self examination, as well as the therapeutic relationship between the patient and psychiatrist, to explore maladaptive coping strategies and relationship patterns of the patient. A thorough understanding of resistance and the core conflictual relationship theme afford the psychiatrist the ability to facilitate this work. In this article, the composite case illustrates some of the psychodynamic psychotherapy techniques that can be employed in a psychotherapy case. In this example, the case is about a certified public accountant that came to treatment because of an acute stressor that put her career goals at risk. An acute episode or event can bring to light chronic and ongoing symptoms, which have had a remitting and relapsing course, and leave the patient unable to compensate on his or her own.

  14. Novel therapeutic approaches for pulmonary arterial hypertension: Unique molecular targets to site-specific drug delivery. (United States)

    Vaidya, Bhuvaneshwar; Gupta, Vivek


    Pulmonary arterial hypertension (PAH) is a cardiopulmonary disorder characterized by increased blood pressure in the small arterioles supplying blood to lungs for oxygenation. Advances in understanding of molecular and cellular biology techniques have led to the findings that PAH is indeed a cascade of diseases exploiting multi-faceted complex pathophysiology, with cellular proliferation and vascular remodeling being the key pathogenic events along with several cellular pathways involved. While current therapies for PAH do provide for amelioration of disease symptoms and acute survival benefits, their full therapeutic potential is hindered by patient incompliance and off-target side effects. To overcome the issues related with current therapy and to devise a more selective therapy, various novel pathways are being investigated for PAH treatment. In addition, inability to deliver anti-PAH drugs to the disease site i.e., distal pulmonary arterioles has been one of the major challenges in achieving improved patient outcomes and improved therapeutic efficacy. Several novel carriers have been explored to increase the selectivity of currently approved anti-PAH drugs and to act as suitable carriers for the delivery of investigational drugs. In the present review, we have discussed potential of various novel molecular pathways/targets including RhoA/Rho kinase, tyrosine kinase, endothelial progenitor cells, vasoactive intestinal peptide, and miRNA in PAH therapeutics. We have also discussed various techniques for site-specific drug delivery of anti-PAH therapeutics so as to improve the efficacy of approved and investigational drugs. This review will provide gainful insights into current advances in PAH therapeutics with an emphasis on site-specific drug payload delivery.

  15. Therapeutic communication and relationships in chronic and complex care. (United States)

    Brownie, Sharon; Scott, Robin; Rossiter, Rachel


    As the population ages and the incidence of chronic diseases and lifestyle-related conditions rises, nurses are increasingly required to provide care for people with a range of chronic (long-term) conditions. The healthcare needs of patients are often complicated by comorbid conditions. Nurses deliver healthcare in the context of the patient's medical conditions, treatment regimens, the healthcare system, and the individual's socioeconomic, personal and family factors, which may include the challenges of social isolation and geographic distance. In such complex circumstances, patients may be perceived as 'difficult' or 'challenging', however, the challenge is not the patient themselves, but the relationship between the nurse and the patient. Communication difficulties can occur between nurses and patients, which may affect the therapeutic relationship and the quality of care provided. This article discusses the communication skills that nurses require to interact effectively with patients who have complex and chronic comorbid conditions. It focuses on therapeutic communication strategies and the nurse-patient relationship, while emphasising the need for nurses to be self-aware when caring for patients with complex healthcare needs.

  16. Expectations for future relationship satisfaction: Unique sources and critical implications for commitment. (United States)

    Baker, Levi R; McNulty, James K; VanderDrift, Laura E


    Contemporary perspectives on relationship commitment posit that intimates decide whether or not to maintain a relationship based on their commitment to that relationship, and that they base such commitment partially on their current satisfaction with that relationship. Nevertheless, given that ending a relationship requires knowing about both the current state of the relationship and the likely future state of the relationship, we propose that people base their commitment to a relationship more on their expected future satisfaction with the relationship than on their current satisfaction with that relationship. Six studies provided evidence for these ideas. Study 1 demonstrated that expected satisfaction is shaped by not only current satisfaction but also several unique indicators of the likelihood of future satisfaction, including anticipated life events, plans to improve the relationship, and individual differences. Then, using a combination of cross-sectional, experimental, and longitudinal methods, Studies 2 through 6 demonstrated that (a) expected satisfaction was a stronger predictor of relationship commitment, maintenance behaviors, and/or divorce than was current satisfaction and (b) expected satisfaction mediated the association between current satisfaction and these outcomes. These findings highlight not only the need to incorporate expected satisfaction into extent perspectives on commitment, but also the importance of expectations for decision-making processes more broadly.

  17. A unique carrier for delivery of therapeutic compounds beyond the blood-brain barrier.

    Directory of Open Access Journals (Sweden)

    Delara Karkan

    Full Text Available BACKGROUND: Therapeutic intervention in many neurological diseases is thwarted by the physical obstacle formed by the blood-brain barrier (BBB that excludes most drugs from entering the brain from the blood. Thus, identifying efficacious modes of drug delivery to the brain remains a "holy grail" in molecular medicine and nanobiotechnology. Brain capillaries, that comprise the BBB, possess an endogenous receptor that ferries an iron-transport protein, termed p97 (melanotransferrin, across the BBB. Here, we explored the hypothesis that therapeutic drugs "piggybacked" as conjugates of p97 can be shuttled across the BBB for treatment of otherwise inoperable brain tumors. APPROACH: Human p97 was covalently linked with the chemotherapeutic agents paclitaxel (PTAX or adriamycin (ADR and following intravenous injection, measured their penetration into brain tissue and other organs using radiolabeled and fluorescent derivatives of the drugs. In order to establish efficacy of the conjugates, we used nude mouse models to assess p97-drug conjugate activity towards glioma and mammary tumors growing subcutaneously compared to those growing intracranially. PRINCIPAL FINDINGS: Bolus-injected p97-drug conjugates and unconjugated p97 traversed brain capillary endothelium within a few minutes and accumulated to 1-2% of the injected by 24 hours. Brain delivery with p97-drug conjugates was quantitatively 10 fold higher than with free drug controls. Furthermore, both free-ADR and p97-ADR conjugates equally inhibited the subcutaneous growth of gliomas growing outside the brain. Evocatively, only p97-ADR conjugates significantly prolonged the survival of animals bearing intracranial gliomas or mammary tumors when compared to similar cumulated doses of free-ADR. SIGNIFICANCE: This study provides the initial proof of concept for p97 as a carrier capable of shuttling therapeutic levels of drugs from the blood to the brain for the treatment of neurological disorders

  18. Unique fractal evaluation and therapeutic implications of mitochondrial morphology in malignant mesothelioma. (United States)

    Lennon, Frances E; Cianci, Gianguido C; Kanteti, Rajani; Riehm, Jacob J; Arif, Qudsia; Poroyko, Valeriy A; Lupovitch, Eitan; Vigneswaran, Wickii; Husain, Aliya; Chen, Phetcharat; Liao, James K; Sattler, Martin; Kindler, Hedy L; Salgia, Ravi


    Malignant mesothelioma (MM), is an intractable disease with limited therapeutic options and grim survival rates. Altered metabolic and mitochondrial functions are hallmarks of MM and most other cancers. Mitochondria exist as a dynamic network, playing a central role in cellular metabolism. MM cell lines display a spectrum of altered mitochondrial morphologies and function compared to control mesothelial cells. Fractal dimension and lacunarity measurements are a sensitive and objective method to quantify mitochondrial morphology and most importantly are a promising predictor of response to mitochondrial inhibition. Control cells have high fractal dimension and low lacunarity and are relatively insensitive to mitochondrial inhibition. MM cells exhibit a spectrum of sensitivities to mitochondrial inhibitors. Low mitochondrial fractal dimension and high lacunarity correlates with increased sensitivity to the mitochondrial inhibitor metformin. Lacunarity also correlates with sensitivity to Mdivi-1, a mitochondrial fission inhibitor. MM and control cells have similar sensitivities to cisplatin, a chemotherapeutic agent used in the treatment of MM. Neither oxidative phosphorylation nor glycolytic activity, correlated with sensitivity to either metformin or mdivi-1. Our results suggest that mitochondrial inhibition may be an effective and selective therapeutic strategy in mesothelioma, and identifies mitochondrial morphology as a possible predictor of response to targeted mitochondrial inhibition.

  19. Unique Diagnostic and Therapeutic Roles of Porphyrins and Phthalocyanines in Photodynamic Therapy, Imaging and Theranostics (United States)

    Josefsen, Leanne B.; Boyle, Ross W.


    Porphyrinic molecules have a unique theranostic role in disease therapy; they have been used to image, detect and treat different forms of diseased tissue including age-related macular degeneration and a number of different cancer types. Current focus is on the clinical imaging of tumour tissue; targeted delivery of photosensitisers and the potential of photosensitisers in multimodal biomedical theranostic nanoplatforms. The roles of porphyrinic molecules in imaging and pdt, along with research into improving their selective uptake in diseased tissue and their utility in theranostic applications are highlighted in this Review.

  20. Synthesis of Some Unique Carbamate Derivatives bearing 2-Furoyl-1-piperazine as a Valuable Therapeutic Agents. (United States)

    Abbasi, Athar; Hussain, Ghulam; Rehman, Aziz Ur; Siddiqui, Zahra; Shah, Adnan Ali; Lodhi, Arif; Khan, Ali; Ashraf, Muhammad; Ain, Qurat Ul; Ahmad, Irshad; Malik, Rabia; Shahid, Muhammad; Mushtaq, Zahid


    The aim of the research work was to synthesize different biologically active carbamate derivatives bearing 2-furoyl-1-piperazine and having modest toxicity. The synthesis was completed as a multiple sequence. The structural confirmation of all the synthesized compounds was obtained by EI-MS, IR and 1H-NMR spectral data. The enzyme inhibition and antibacterial potential of the synthesized compounds was evaluated. To find the utility of the prepared compounds as possible therapeutic agents their cytotoxicity was also checked. All the compounds were active against acetylcholinesterase enzyme, especially 12 and 14 showed very good inhibitory potential relative to Eserine, a reference standard. Almost all the compounds showed good activities against both Gram-positive and Gram-negative bacterial strains.

  1. Exploring the surfaceome of Ewing sarcoma identifies a new and unique therapeutic target (United States)

    Town, Jennifer; Pais, Helio; Harrison, Sally; Bataille, Carole; Bunjobpol, Wilawan; Zhang, Jing; Rabbitts, Terence H.


    The cell surface proteome of tumors mediates the interface between the transformed cells and the general microenvironment, including interactions with stromal cells in the tumor niche and immune cells such as T cells. In addition, the cell surface proteome of individual cancers defines biomarkers for that tumor type and potential proteins that can be the target of antibody-mediated therapy. We have used next-generation deep RNA sequencing (RNA-seq) coupled to an in-house database of genes encoding cell surface proteins (herein referred to as the surfaceome) as a tool to define a cell surface proteome of Ewing sarcoma compared with progenitor mesenchymal stem cells. This subtractive RNA-seq analysis revealed a specific surfaceome of Ewing and showed unexpectedly that the leucine-rich repeat and Ig domain protein 1 (LINGO1) is expressed in over 90% of Ewing sarcoma tumors, but not expressed in any other somatic tissue apart from the brain. We found that the LINGO1 protein acts as a gateway protein internalizing into the tumor cells when engaged by antibody and can carry antibody conjugated with drugs to kill Ewing sarcoma cells. Therefore, LINGO1 is a new, unique, and specific biomarker and drug target for the treatment of Ewing sarcoma. PMID:26979953

  2. A unique therapeutic approach to emesis and itch with a proanthocyanidin-rich genonutrient

    Directory of Open Access Journals (Sweden)

    Wallace John L


    Full Text Available Abstract Background We examined the therapeutic potential of a proprietary Croton palanostigma extract (Zangrado® in the management of emesis and itch. Methods Emesis was induced in ferrets with morphine-6-glucuronide (0.05 mg/kg sc in the presence of Zangrado (3 mg/kg, ip and the cannabinoid receptor 1 antagonist, AM 251 (5 mg/kg, ip. Topical Zangrado (1% was assessed for anti-pruretic actions in the 5-HT-induced scratching model in rats and evaluated in capsaicin-induced gastric hyperemia as measured by laser doppler flow. In the ApcMinmouse model of precancerous adenomatosis polyposis, mice received Zangrado (100 μg/ml in drinking water from the age of 6 – 16 weeks for effects on polyp number. In RAW 264.7 cells Zangrado was examined for effects on lipopolysaccharide-induced nitrite production. Results Zangrado was a highly effective anti-emetic, reducing morphine-induced vomiting and retching by 77%. These benefits were not associated with sedation or hypothermia and were not reversed by cannabinoid receptor antagonism. Itch responses were blocked in both the morphine and 5-HT models. Zangrado did not exacerbate the ApcMincondition rather health was improved. Capsaicin-induced hyperemia was blocked by Zangrado, which also attenuated the production of nitric oxide by activated macrophages. Conclusion Zangrado is an effective anti-emetic and anti-itch therapy that is devoid of common side-effects, cannabinoid-independent and broadly suppresses sensory afferent nerve activation. This complementary medicine represents a promising new approach to the management of nausea, itch and irritable bowel syndrome.

  3. What determines the relationship between color naming, unique hues, and sensory singularities: Illuminations, surfaces, or photoreceptors? (United States)

    Witzel, Christoph; Cinotti, François; O'Regan, J Kevin


    The relationship between the sensory signal of the photoreceptors on one hand and color appearance and language on the other hand is completely unclear. A recent finding established a surprisingly accurate correlation between focal colors, unique hues, and so-called singularities in the laws governing how sensory signals for different surfaces change across illuminations. This article examines how this correlation with singularities depends on reflectances, illuminants, and cone sensitivities. Results show that this correlation holds for a large range of illuminants and for a large range of sensors, including sensors that are fundamentally different from human photoreceptors. In contrast, the spectral characteristics of the reflectance spectra turned out to be the key factor that determines the correlation between focal colors, unique hues, and sensory singularities. These findings suggest that the origins of color appearance and color language may be found in particular characteristics of the reflectance spectra that correspond to focal colors and unique hues.

  4. Social representation of therapeutic relationship among cognitive-behavioral psychotherapists. (United States)

    Gelo, Omar Carlo Gioacchino; Ziglio, Roberto; Armenio, Stefania; Fattori, Francesco; Pozzi, Maura


    The present study investigates the content and structure of the social representation (SR) that cognitive-behavioral (CBT) psychotherapists have of the therapeutic relationship (TR), through a discovery-oriented, mixed-methods approach. For this purpose, our reference point was social representation theory, in particular, the theory of the central nucleus (Abric, 2003; Moscovici, 1961). Data came from a sample of 63 CBT therapists. The results enabled us to identify a series of contents marking CBTs SR of the TR that overlap with the current pan-theoretical conceptualization of this construct. The results also allowed us to identify the complex, clear, and stratified organization of these contents, which are characteristics of a majority and of a minority of the sample studied. These results are discussed with regard of their theoretical, methodological, and practical implications. (PsycINFO Database Record

  5. Relationships with mother, teacher, and peers: unique and joint effects on young children's self-concept. (United States)

    Verschueren, Karine; Doumen, Sarah; Buyse, Evelien


    This study tested the unique and joint effects of three significant relationships in young children's social lives, namely their relationships with mother, teacher, and peers, on three dimensions of self-concept (general, academic, and social). A sample of 113 children participated. Mother-child attachment quality was observed in preschool. In first grade, teacher ratings of teacher-child relationship quality, peer ratings of peer acceptance, and child reports of self-concept were administered. The results revealed domain-specific links between social relationships and self-concept dimensions. Specifically, academic self-concept related to teacher-child relationship quality, social self-concept to peer acceptance, and general self-concept to the quality of attachment to mother. Moreover, an indirect effect was revealed of earlier mother-child attachment quality on the academic dimension of self through its effect on current adult-child relationships in school. This way, the study uncovered the pathways through which significant social relationships shape the formation of young children's self-concept.

  6. The therapeutic relationship and adherence to antipsychotic medication in schizophrenia.

    Directory of Open Access Journals (Sweden)

    Rosemarie McCabe

    Full Text Available OBJECTIVE: Previous research has shown that a better therapeutic relationship (TR predicts more positive attitudes towards antipsychotic medication, but did not address whether it is also linked with actual adherence. This study investigated whether the TR is associated with adherence to antipsychotics in patients with schizophrenia. METHODS: 134 clinicians and 507 of their patients with schizophrenia or a related psychotic disorder participated in a European multi-centre study. A logistic regression model examined how the TR as rated by patients and by clinicians is associated with medication adherence, adjusting for clinician clustering and symptom severity. RESULTS: Patient and clinician ratings of the TR were weakly inter-correlated (r(s = 0.13, p = 0.004, but each was independently linked with better adherence. After adjusting for patient rated TR and symptom severity, each unit increase in clinician rated TR was associated with an increase of the odds ratio of good compliance by 65.9% (95% CI: 34.6% to 104.5%. After adjusting for clinician rated TR and symptom severity, for each unit increase in patient rated TR the odds ratio of good compliance was increased by 20.8% (95% CI: 4.4% to 39.8%. CONCLUSIONS: A better TR is associated with better adherence to medication among patients with schizophrenia. Patients' and clinicians' perspectives of the TR are both important, but may reflect distinct aspects.

  7. Enhancing adult therapeutic interpersonal relationships in the acute health care setting: an integrative review (United States)

    Kornhaber, Rachel; Walsh, Kenneth; Duff, Jed; Walker, Kim


    Therapeutic interpersonal relationships are the primary component of all health care interactions that facilitate the development of positive clinician–patient experiences. Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

  9. A unique natural selective kappa-opioid receptor agonist, salvinorin A, and its roles in human therapeutics. (United States)

    Cruz, André; Domingos, Sara; Gallardo, Eugenia; Martinho, Ana


    Until the mid-60s, only the Mazatecs, an indigenous group from Oaxaca, Mexico, used Salvia Divinorum (S. divinorum) due to its hallucinogen properties. Later it was found that the hallucinogen effects of this plant were caused by the presence of a neoclerodane diterpene Salvinorin A (salvinorin A), which is a highly selective agonist of kappa-opioid receptor (KOR) that cause more intense hallucinations than the common hallucinogens as lysergic acid, mushrooms, ecstasy and others. In fact, smoking of only 200-500 μg of S. divinorum leaves is enough to produce these effects thus making it the most potent natural occurring hallucinogen known. Due to its legal status in various countries, this compound has gained a worldwide popularity as a drug of abuse with an easy access through smartshops and internet. Furthermore, salvinorin A gathered an increased interest in the scientific community thanks to its unique structure and properties, and various studies demonstrated that salvinorin A has antinociceptive, antidepressant, in some circumstances pro-depressant and anti-addictive effects that have yielded potential new avenues for research underlying salvinorin A and its semi-synthetic analogs as therapeutic agents.

  11. Hope-inspiring therapeutic relationships, professional expectations and social inclusion for young people with psychosis. (United States)

    Berry, Clio; Greenwood, Kathryn


    Personal recovery accounts suggest that a positive therapeutic relationship with an optimistic mental health professional may facilitate social inclusion. However, little empirical research has investigated the role of the therapeutic relationship in social outcomes or explored potential mechanisms of change within community psychosis care. This study investigated the direct predictive associations of the therapeutic relationship and professional expectancies for social inclusion and vocational activity for young people with psychosis, and indirect associations through hopefulness. Young people with psychosis and their main mental health professional (n=51 dyads) participated across two time points. Measures of therapeutic relationships, professional expectancies, and vocational activity were obtained at baseline. Measures of hopefulness, social inclusion and vocational activity were obtained at follow-up. Direct and indirect associations between variables were analysed using path modelling. Directed path models were consistent with a positive therapeutic relationship and positive professional expectancies predicting social inclusion and vocational activity through mediation by increased patient domain-specific hopefulness. The professional-rated therapeutic relationship more directly predicts change in vocational activity status. Change in vocational activity status predicts increased patient hopefulness. The therapeutic relationship between professionals and young people with psychosis appears hope-inspiring and important to patients' social inclusion and vocational outcomes. Vocational activity may produce reciprocal gains in hopefulness. Copyright © 2015 Elsevier B.V. All rights reserved.

  12. A Systematic Review of the Effect of Therapists' Internalized Models of Relationships on the Quality of the Therapeutic Relationship. (United States)

    Steel, Catherine; Macdonald, James; Schroder, Thomas


    Previous reviews have found equivocal evidence of an association between therapists' internalized relational models and the therapeutic relationship and have neglected empirical literature based on Sullivan's notion of introject. This review expanded upon previous reviews to examine the effect of therapist internalized relational models on a broader conceptualization of the therapeutic relationship. Systematic search processes identified 22 papers measuring therapist attachment and/or introject and therapeutic relationship: 19 on therapist attachment, 5 on introject with 2 overlapping. Overall, despite heterogeneity in design and variable methodological quality, evidence suggests that therapist attachment affects therapeutic relationship quality, observed in client-rated evaluation, therapist negative countertransference, empathy, and problems in therapy. Interaction effects between client and therapist attachment style were also found. Evidence suggesting that therapist introject also affects therapeutic relationship quality, including therapists' manner and feelings toward their clients, was stronger. Evidence clearly shows that therapists' internalized relational models affect the therapeutic relationship. More research is necessary to clarify exactly how therapist and client internalized relational models interact and translate these findings into clinical practice. © 2017 Wiley Periodicals, Inc.

  14. Therapeutic Relationship and Study Adherence in a Community Health Worker-Led Intervention. (United States)

    Mundorf, Christopher; Shankar, Arti; Peng, Terrance; Hassan, Anna; Lichtveld, Maureen Y


    Community health workers (CHWs) are increasingly utilized to reach low-resource communities. A critical domain influencing success is the CHWs' ability to create and maintain a therapeutic relationship with the participants they serve. A limited evidence base exists detailing this construct, and evaluating CHW-participant relationships in the context of CHW-led programs. In a longitudinal study design, data on this therapeutic relationship were collected [as captured using The Scale to Assess the Therapeutic Relationship in Community Mental Health Care (STAR)] on 141 participants who had been assigned to a CHW during their perinatal period. Results indicate that therapeutic relationship was associated with the participant's psychosocial health, and independently predicted study adherence in the longitudinal intervention. Changes in therapeutic relationship over the months following birth were strongly associated with changes in anxiety and depression symptoms. A trustful relationship is critical in ensuring CHWs can effectively reach the population they serve. The findings offer additional psychometric evidence of the uses and benefits of STAR outside of the traditional clinical setting in the context of public health research.

  15. Multicenter Study of Posaconazole Therapeutic Drug Monitoring: Exposure-Response Relationship and Factors Affecting Concentration


    Dolton, Michael J; Ray, John E.; Chen, Sharon C.-A.; Ng, Kingsley; Pont, Lisa; McLachlan, Andrew J


    Posaconazole has an important role in the prophylaxis and salvage treatment of invasive fungal infections (IFIs), although poor and variable bioavailability remains an important clinical concern. Therapeutic drug monitoring of posaconazole concentrations has remained contentious, with the use of relatively small patient cohorts in previous studies hindering the assessment of exposure-response relationships. This multicenter retrospective study aimed to investigate relationships between posaco...

  16. Need for uniqueness as a mediator of the relationship between face consciousness and status consumption in China. (United States)

    Sun, Gong; Chen, Jun; Li, Jie


    Strong economic development in China has led to a surge in status consumption as a means of gaining face. In Eastern culture, people interpret uniqueness as status distinction rather than separateness or deviance. This type of uniqueness can be used to meet others' expectations and gain social approval. Thus its relationship with face consciousness and status consumption is to be expected. This study investigates 2 hypotheses: (a) Face consciousness has a positive effect on status consumption and (b) Consumer need for uniqueness mediates the relationship between face consciousness and status consumption. Two-hundred and forty-six working respondents in eastern China completed a survey. Regression analysis of the results supported both hypotheses.

  17. Therapeutic Value of the Human Being-Animal Relationship

    Directory of Open Access Journals (Sweden)

    Mirela Samfira


    Full Text Available In this paper the authors try to open a window towards the emotional, psychological and social benefits of a new form of therapy – the zoo-therapy (the therapy intermediated by animals. The strong relationship between men and animals as well as its material advantages are very well known but their impact on the conditions, on the stress decrease, on the prevention of some types of cancer, on the rise of self-esteem or school performance is still little known. The emotional and medical benefits can be successfully obtained in old people, children, chronic patients, or children with autism – even in people who are not the animals’ owners. Thanks to this information, farmers can choose new alternatives for their work with the animals, in the treatment of different kinds of diseases and helped by specialists.

  18. Daniel Deronda and Gwendolen Harleth: a therapeutic relationship? (United States)

    Paris, Bernard J


    In Daniel Deronda, George Eliot presents Gwendolen as having been rescued by Daniel, and most commentators have agreed, with many comparing the relationship to that of patient and therapist. These commentators have allowed themselves to be unduly influenced by George Eliot's interpretations and judgments and have ignored the concrete depiction of her characters. While we are being told that Gwendolen is undergoing a conversion in which she develops a new consciousness, a new soul, we are being shown a character who is full of rage, self-hatred, and despair. Instead of leading her in the direction of psychological health, Deronda offers her his own defenses and fosters her dependency on him. Despite the upbeat tone of the ending, her prospects after he leaves England seem very bleak.

  1. Histone deacetylase inhibitor pracinostat in doublet therapy: a unique strategy to improve therapeutic efficacy and to tackle herculean cancer chemoresistance. (United States)

    Ganai, Shabir Ahmad


    Context Histone deacetylase inhibitors (HDACi) have shown promising results in neurodegeneration and cancer. Hydroxamate HDACi, including vorinostat, have shown encouraging results in haematological malignancies, but the poor pharmacokinetic of these inhibitors leads to insufficient tumour concentration limiting their application against solid malignancies. Objective This article deals with novel HDAC inhibitor pracinostat (SB939) and delineates its therapeutic role in solid and haematological malignancies. The article provides rigorous details about the underlying molecular mechanisms modulated by pracinostat to exert cytotoxic effect. The article further highlights the doublet therapy that may be used to tackle monotonous cancer chemoresistance. Methods Both old and the latest literature on pracinostat was retrieved from diverse sources, such as PubMed, Science Direct, Springer Link, general Google search using both pracinostat and SB939 keywords in various ways: after thorough evaluation the topic which can fulfil the current gap was chosen. Results Pracinostat shows potent anticancer activity against both solid and haematological malignancies compared to the FDA-approved drug vorinostat. This marvellous inhibitor has better physicochemical, pharmaceutical and pharmacokinetic properties than the defined inhibitor vorinostat. Pracinostat has  >100-fold more affinity towards HDACs compared to other zinc-dependent metalloenzymes and shows maximum efficacy when used in doublet therapy. Conclusion Pracinostat shows potent anticancer activity even against therapeutically challenging cancers when used in doublet therapy. However, the triplet combination studies of the defined inhibitor that may prove even more beneficial are still undone, emphasizing the desperate need of further research in the defined gap.

  2. The relationship between acculturative stress and eating disorder symptoms: is it unique from general life stress? (United States)

    Kroon Van Diest, Ashley M; Tartakovsky, Margarita; Stachon, Caitlin; Pettit, Jeremy W; Perez, Marisol


    The purpose of the current study was to expand upon the literature examining the relationship between acculturative stress and eating disorder symptoms among different ethnic groups. Specifically, acculturative stress was explored as a moderator of the relationship between body dissatisfaction and eating disorder symptoms among ethnic minority women. Additionally, the distinction between acculturative stress and general life stress in predicting eating disorder symptoms was assessed. Participants consisted of 247 undergraduate women, all of whom were members of an ethnic minority group including African Americans, Asian Americans, and Latinas. Acculturative stress was found to moderate the relationship between body dissatisfaction and eating disorder symptoms, but only among African American women. Acculturative stress was also found to significantly predict bulimic symptoms above and beyond general life stress among African American, Asian American, and Latina women.

  8. Unique relationships between facets of mindfulness and eating pathology among female smokers. (United States)

    Adams, Claire E; Apperson McVay, Megan; Kinsaul, Jessica; Benitez, Lindsay; Vinci, Christine; Stewart, Diana W; Copeland, Amy L


    Female smokers often have higher levels of eating disorder symptoms than non-smokers, and concerns about eating and weight might interfere with smoking cessation. Thus, it is critical to identify factors to promote healthier eating and body image in this population. Initial research suggests that specific aspects of trait mindfulness predict lower body dissatisfaction and eating disorder symptoms among non-smokers. However, these relationships are unknown among smokers. The current study examined associations between facets of trait mindfulness and eating disorder symptoms in 112 college female smokers (83% Caucasian; mean age 20 years, SD=1.69). After controlling for relevant sociodemographic variables, Describing and Nonjudging facets of mindfulness predicted lower bulimic symptoms and body dissatisfaction (psmindfulness facets are related to lower eating disorder symptoms among smokers, whereas other facets are not associated or have a positive relationship with these symptoms. Mindfulness-based interventions focusing on Describing, Nonjudging, and Acting with Awareness may help to reduce eating pathology among female smokers, which could potentially improve smoking cessation rates in this population.

  9. Relationship between aggression, interpersonal style, and therapeutic alliance during short-term psychiatric hospitalization. (United States)

    Cookson, Amy; Daffern, Michael; Foley, Fiona


    Aggression during psychiatric hospitalization is frequent, problematic, and a major challenge for nurses and mental health services more generally. The strength of the therapeutic alliance between nursing staff and patients has been posited as an important protective factor that can limit the likelihood of aggression. This study examined the relationship between interpersonal style, perceived coercion, and psychiatric symptoms on the therapeutic alliance between patients and staff, and how each, in turn, is related to aggression. Participants in this study were 79 patients admitted to an acute psychiatric hospital. Each participant was interviewed to determine perceived coercion, symptoms of psychiatric illness, interpersonal style, and therapeutic alliance. Incidents of aggression were recorded at discharge through a review of incident forms, file review, and interviews with unit nursing staff. The results showed that a hostile-dominant interpersonal style and symptoms of paranoia predicted poor therapeutic alliance, contributing 14% of the variance in therapeutic alliance scores. A dominant interpersonal style predicted aggression towards staff. Therapeutic alliance, perceived coercion, and symptoms of psychiatric illness did not predict aggression. Implications for engagement in treatment and the prevention of aggression are discussed.

  10. The impact of shame on the therapeutic alliance and intimate relationships. (United States)

    Black, Rebecca S A; Curran, David; Dyer, Kevin F W


    This study examined the role of shame coping styles and state shame in predicting the therapeutic alliance and intimate relationship functioning in individuals with mental health problems. A sample of 50 treatment-receiving adults aged 21 to 67 years with a mix of common mental health difficulties was recruited from a clinical psychology service. Participants were given questionnaire measures of shame states, shame coping styles, intimate relationship functioning, and the therapeutic alliance. Regression analyses indicated that the shame coping strategy of physical and psychological withdrawal was the primary risk factor for development of a less effective therapeutic alliance. Both withdrawal and attack self coping styles were significant predictors of impaired intimate relationship functioning. These findings have implications for the theoretical role of shame in mental health presentations as well as the potential for internalizing shame coping styles (i.e., withdrawal, attack self) to act as a barrier to successful therapy and interpersonal relationships. The inclusion of shame-focused assessments and interventions in the initial stages of treatment with clients exhibiting these strategies could improve prognosis. © 2013 Wiley Periodicals, Inc.

  12. Using cognitive behavioural therapy with complex cases: using the therapeutic relationship to change core beliefs. (United States)

    Binnie, James


    Cognitive Behavioural Therapy (CBT) is often perceived as a manualised, symptom focused, surface level approach. This article aims to reflect on working with complex clinical presentations and explore how third wave CBT can be effectively integrated into standard cognitive behavioural interventions. To achieve these aims, a case study of a CBT assessment and treatment is presented. The interventions used are described in detail. The focus changes from the more traditional symptom-led interventions to third wave approaches based on the therapeutic relationship. When the focus was redirected towards the therapeutic relationship then real change occurred, quickly and powerfully. Reflections on the process are discussed and the overall approach used was evaluated with an action plan developed to enhance future clinical practice. It is hoped that this study can help CBT be viewed as a comprehensive form of psychotherapy.

  13. Perspectives of Treatment Providers and Clients with Serious Mental Illness Regarding Effective Therapeutic Relationships. (United States)

    Easter, Alison; Pollock, Michele; Pope, Leah Gogel; Wisdom, Jennifer P; Smith, Thomas E


    This study explores the nature of clinical therapeutic relationships between mental health treatment providers and high-need clients with serious mental illness who had recently discontinued treatment. Semi-structured qualitative interviews of 56 clients with serious mental illness who had recently discontinued care and 25 mental health treatment providers were completed. Both clients with serious mental illness and treatment providers emphasized the importance of client-focused goal setting, time and availability of treatment providers, a caring approach, and trust and honesty in the relationship. However, clients with serious mental illness placed greater emphasis on goals involving tangible services, a notable area of discord between the two groups. Individuals with serious mental illness and treatment providers agreed regarding several key elements to a positive clinical relationship. Further attention to client goals related to tangible services may serve to improve relationships between treatment providers and high-need clients with serious mental illness.

  14. A Unique Laboratory to Explore Soil-Wine Relationships, North Canterbury, New Zealand (United States)

    Harrison, R.; Tomasino, E.; Tonkin, P.; Webb, T.; Burns, S. F.; Weersing, M.


    Zealand are distinguishable from one another by smell and taste. In these environments, cultural (management) decisions are adapted to maximize so-called physiological ripeness that tend to work against simple relationships between say latitude and mean temperature. Even within the conceptual framework provided by climate as a determinant of berry composition at harvest (and hence, presumably, wine composition), there is a recognition that landscapes and soils are important modifiers, particular of heat and water balance but also of nutrients and uptake of other components through root systems. The contrasting array of soils in North Canterbury provides an opportunity to validate the soil contribution to terroir.

  15. The therapeutic relationship and patients’ experience of interpersonal bonds – research conducted in outpatient mental health care

    Directory of Open Access Journals (Sweden)

    Sosnowska, Małgorzata


    Full Text Available Aim. To study the therapeutic relationship in community mental health care, in terms of patients’ socioeconomic status and their experience of interpersonal bonds.Method. Research study included patients treated in community mental health care (N=64 who met the criteria for psychosis, and the professionals who managed their treatment. Patients’ psychotic symptoms were measured with the use of the PANSS scale, whereas the STAR scale was used to assess the therapeutic relationship, in separate models for evaluating patients and clinicians. The patients’ socioeconomic data was collected, as was information about the therapists.Results. Patients’ experience of bonds, understood as a current or past marriage or parenthood, correlated positively with their views on the therapeutic relationship. Patients assessed therapeutic relationships more favourably than their therapists. Therapists assessed the therapeutic relationship in the “positive clinicianinput” dimension more favourably than did financially independent patients.Conclusions. Patients’ experience of interpersonal bonds enhances their chances of establishing a successful therapeutic relationship and it also contributes to establishing a good therapeutic relationship in the opinion of therapists.

  16. Examining the therapeutic relationship and confronting resistances in psychodynamic psychotherapy: a certified public accountant case. (United States)

    Manetta, Christopher T; Gentile, Julie P; Gillig, Paulette Marie


    Psychodynamic psychotherapy is effective for a variety of mental health symptoms. This form of psychotherapy uses patient self reflection and self examination, as well as the therapeutic relationship between the patient and psychiatrist, to explore maladaptive coping strategies and relationship patterns of the patient. A thorough understanding of resistance and the core conflictual relationship theme afford the psychiatrist the ability to facilitate this work. In this article, the composite case illustrates some of the psychodynamic psychotherapy techniques that can be employed in a psychotherapy case. In this example, the case is about a certified public accountant that came to treatment because of an acute stressor that put her career goals at risk. An acute episode or event can bring to light chronic and ongoing symptoms, which have had a remitting and relapsing course, and leave the patient unable to compensate on his or her own.

  17. Intimidades: confianza, gender, and hierarchy in the construction of Latino-Latina therapeutic relationships. (United States)

    Bracero, W


    The intimate nature of psychotherapy requires psychotherapists be educated to deal with the sexualization of the sharing of intimate feelings and interpersonal closeness. Latino cultures have relatively rigid sex role expectations and norms that privilege men at the expense of women. Experiences of emotional intimacy threaten this Latino cultural discourse of boundaries between men and women and may lead to impasses in therapy and enactments of pathogenic aspects of machismo and marianismo in the therapeutic relationship. Clinical vignettes illustrating the embeddedness of such gender discourses within therapeutic conversations between a Latino therapist and his Latina clients are presented, with discussion of how an intersubjective--relational approach can be used to deconstruct oppressive machista metaphors and cultural narratives and then aid in the coconstruction of reparative narratives within a context of intergender mutuality.

  18. Assessing physical functioning on pain management programmes: the unique contribution of directly assessed physical performance measures and their relationship to self-reports. (United States)

    Guildford, Beth J; Jacobs, Clair M; Daly-Eichenhardt, Aisling; Scott, Whitney; McCracken, Lance M


    Physical functioning is a recommended outcome domain for pain management programmes. It can be assessed by self-report and by direct assessment of performance. Although physical performance measures may provide unique and useful information about patient functioning over and above self-report measures, it is not entirely clear which of the many possible performances to assess. This study investigated a battery of three directly assessed physical performance measures and their relationship to three currently used self-report measures of general health and functioning. The three performance measures were sensitive to treatment; patients performed significantly better on all three measures following completion of the pain management programme. The three performance measures were shown to represent a single underlying dimension, and there was a significant degree of overlap between them. The performance measures were shown to be relevant in explaining variation in the self-report measures, as well as to offer a clinically relevant different dimension of assessment to self-report. Future research could focus on developing performance-based measures that capture quality of movement and that are sensitive to relevant processes of therapeutic change.

  19. Experiences of therapeutic relationships on hospital wards, dissociation, and making connections. (United States)

    Parry, Sarah; Lloyd, Mike; Simpson, Jane


    An interpretive phenomenological analysis sought to explore how people reporting moderate to high levels of dissociation experienced relationships with multidisciplinary hospital ward staff. Three superordinate themes were developed. First, the theme "multiple me and multiple them" explores the instability experienced by the participants as they managed their dissociative experiences alongside many inconsistencies. Second, "recognizing, meeting, or neglecting interpersonal and care needs" reflects on participants' needs within therapeutic relationships. Third, "between the needs of the internal system: navigating between 'better on my own' and 'someone to talk to'" discusses the confusion and understanding around dissociation and the importance of working with parts, not around them. Findings suggested that the current culture of some hospital wards directly influenced participants' distress, which could lead to further dissociation as a means of coping with perceived threats. Reflections on relational complexities and developing ward-based treatment are discussed.

  20. Therapeutic relationship on the web: to face or not to face?

    Directory of Open Access Journals (Sweden)

    Ana Sfoggia


    Full Text Available In this age of unprecedented expansion of media and information dissemination and sharing, the use of electronic means should be reconsidered. The use of new technologies should be studied to understand how it may affect the relationship between patient and therapist during psychotherapy or psychoanalytic treatments. This study offers a critical discussion of the effect of technologies on clinical practice, and vignettes are used to describe their impact on frame, anonymity, abstinence and therapeutic neutrality. Transfer and countertransference issues resulting from these changes are also discussed. The potential benefits of new technologies in psychotherapy are appreciated, but the authors draw attention to the need to reflect about the presence of the therapist in those technologies and the preservation of the therapeutic setting, so that a satisfactory progression of the work of the dyad is ensured. This study also discusses the use of technologies in the expansion of learning and application of the therapeutic technique to overcome geographic and time barriers, among others.

  1. The relationship between patients' knowledge of diabetes therapeutic goals and self-management behaviour, including adherence. (United States)

    Waheedi, Mohammad; Awad, Abdelmoneim; Hatoum, Hind T; Enlund, Hannes


    Background The Middle East region has one the highest prevalence rates of diabetes in the world. Little is known about the determinants of adherence and the role of knowledge in diabetes self-management within these populations. Objective To investigate the relationship between patients knowledge of diabetes therapeutic targets with adherence to self-care measures in a sample of patients with type 2 diabetes in Kuwait. Setting Primary care chronic care clinics within the Ministry of Health of Kuwait. Methods A cross sectional survey was carried out with 238 patients from six clinics. A multistage stratified clustered sampling method was used to first randomly select the clinics and the patients. Self-reported adherence to three behaviours: medication taking, diet and physical activity. Results Respondents were able to correctly report a mean (SD) of 1.6 (1.3) out of 5 of the pre-specified treatment targets. Optimal adherence to physical activity, diet and medications was reported in 25, 33 and 47 % of the study cohort, respectively. A structural equation model analysis showed better knowledge of therapeutic goals and own current levels translated into better adherence to medications, diet and physical activity. Conclusion Knowledge of therapeutic goals and own recent levels is associated with adherence to medications, diet, or physical activity in this Kuwaiti cohort of patients with diabetes. Low adherence to self-care management and poor overall knowledge of diabetes is a big challenge to successful diabetes care in Kuwait.

  2. Motive-oriented therapeutic relationship building for patients diagnosed with schizophrenia

    Directory of Open Access Journals (Sweden)

    Stefan eWestermann


    Full Text Available Treatment options for patients with schizophrenia demand further improvement. One way to achieve this improvement is the translation of findings from basic research into new specific interventions. Beyond that, addressing the therapy relationship has the potential to enhance both pharmacological and non-pharmacological treatments. This paper introduces motive-oriented therapeutic relationship (MOTR building for schizophrenia. MOTR enables therapists to proactively adapt to their patient’s needs and to prevent problematic behaviors. For example, a patient might consider medication as helpful in principle, but the rejection of medication might be one of his few remaining means for his acceptable motive to stay autonomous despite hospitalization. A therapist who is motive-oriented proactively offers many degrees of freedom to this patient in order to satisfy his need for autonomy and to weaken the motivational basis for not taking medication. MOTR makes use of findings from basic and psychotherapy research and is generic in this respect, but at the same time guides therapeutic action precisely and flexibly in a patient oriented way.

  3. The relationship between sluggish cognitive tempo and burnout symptoms in psychiatrists with different therapeutic approaches. (United States)

    Gül, Ahmet; Gül, Hesna; Özkal, Ummuhan Ceviz; Kıncır, Zeliha; Gültekin, Gozde; Emul, Hacı Murat


    Burnout is a serious problem for psychiatrists that has implications for clinical practice and personal health. While burnout is known to affect cognitive functions, no studies have examined the relationship between sluggish cognitive tempo (SCT) and burnout. This study aimed to examine this relationship and related factors as socio-demographic, occupational environment in psychiatrists. Participants(n=201, aged between 25 and 52 years,57.7% female) completed socio-demographic information form, Maslach Burnout Inventory and SCT Scale. According to our results, we have shown that total burnout scores and emotional exhaustion (EE) scores were significantly higher in psychiatrists with SCT. SCT scores were positively correlated with mean total burnout, EE, and depersonalization scores. We did not find any differences between subgroups according to departments, therapeutic approaches and gender. In conclusion, we want to highlight that psychiatrists with SCT were more proneness to general burnout symptoms and were more emotionally exhausted regardless of their therapeutic approach or their profession as adult or child/adolescent psychiatrists.

  4. Structure-affinity relationships of a unique nicotinic ligand: N(1)-dimethyl-N(4)-phenylpiperazinium iodide (DMPP). (United States)

    Romanelli, M N; Manetti, D; Scapecchi, S; Borea, P A; Dei, S; Bartolini, A; Ghelardini, C; Gualtieri, F; Guandalini, L; Varani, K


    DMPP is a well-known nicotinic agonist that does not fit any proposed pharmacophore for nicotinic binding and represents a unique ligand among the hundreds of nicotinic agonists studied in the past decades. A systematic modulation of the chemical structure of DMPP, aimed to establish its structure-affinity relationships, is reported. The research has allowed to identify molecules such as 11c, 13c, 14c, and 28c, with affinities for alpha(4)beta(2) receptors in the low nanomolar range, some 2 orders of magnitude lower than the lead compound. The agonistic properties of the most interesting compounds have been assessed by measuring their analgesic activity on mice (hot-plate test). Another result of the research was the identification of DMPP analogues, such as 3a (K(i) = 90 nM) and 14b (K(i) = 180 nM), that maintain affinity for the central nicotinic receptor when the ammonium function is changed into an aminic one and are therefore possible leads for drug development in neurodegenerative diseases.

  5. Posaconazole exposure-response relationship: evaluating the utility of therapeutic drug monitoring. (United States)

    Dolton, Michael J; Ray, John E; Marriott, Deborah; McLachlan, Andrew J


    Posaconazole has become an important part of the antifungal armamentarium in the prophylaxis and salvage treatment of invasive fungal infections (IFIs). Structurally related to itraconazole, posaconazole displays low oral bioavailability due to poor solubility, with significant drug interactions and gastrointestinal disease also contributing to the generally low posaconazole plasma concentrations observed in patients. While therapeutic drug monitoring (TDM) of plasma concentrations is widely accepted for other triazole antifungal agents such as voriconazole, the utility of TDM for posaconazole is controversial due to debate over the relationship between posaconazole exposure in plasma and clinical response to therapy. This review examines the available evidence for a relationship between plasma concentration and clinical efficacy for posaconazole, as well as evaluating the utility of TDM and providing provisional target concentrations for posaconazole therapy. Increasing evidence supports an exposure-response relationship for plasma posaconazole concentrations for prophylaxis and treatment of IFIs; a clear relationship has not been identified between posaconazole concentration and toxicity. Intracellular and intrapulmonary concentrations have been studied for posaconazole but have not been correlated to clinical outcomes. In view of the high mortality and cost associated with the treatment of IFIs, increasing evidence of an exposure-response relationship for posaconazole efficacy in the prevention and treatment of IFIs, and the common finding of low posaconazole concentrations in patients, TDM for posaconazole is likely to be of significant clinical utility. In patients with subtherapeutic posaconazole concentrations, increased dose frequency, administration with high-fat meals, and withdrawal of interacting medications from therapy are useful strategies to improve systemic absorption.

    Idiopathic or immune thrombocytopenia (ITP) is a serious clinical disorder involving the destruction of platelets by macrophages. Small molecule therapeutics are highly sought after to ease the burden on current therapies derived from human sources. Earlier, we discovered that dimers of five-membered heterocycles exhibited potential to inhibit phagocytosis of human RBCs by macrophages. Here, we reveal a structure-activity relationship of the bis-pyrazole class of molecules with -C-C-, -C-N- and -C-O- linkers, and their evaluation as inhibitors of phagocytosis of antibody-opsonized human RBCs as potential therapeutics for ITP. We have uncovered three potential candidates, 37, 47 and 50, all carrying a different linker connecting the two pyrazole moieties. Among these compounds, hydroxypyrazole derivative 50 is the most potent compound with an IC50 of 14 ± 9 μM for inhibiting the phagocytosis of antibody-opsonized human RBCs by macrophages. None of the compounds exhibited significant potential to induce apoptosis in peripheral blood mononuclear cells (PBMCs). Current study has revealed specific functional features, such as up to 2-atom spacer arm and alkyl substitution at one of the N(1) positions of the bivalent pyrazole core to be important for the inhibitory activity.

  7. Multicenter study of posaconazole therapeutic drug monitoring: exposure-response relationship and factors affecting concentration. (United States)

    Dolton, Michael J; Ray, John E; Chen, Sharon C-A; Ng, Kingsley; Pont, Lisa; McLachlan, Andrew J


    Posaconazole has an important role in the prophylaxis and salvage treatment of invasive fungal infections (IFIs), although poor and variable bioavailability remains an important clinical concern. Therapeutic drug monitoring of posaconazole concentrations has remained contentious, with the use of relatively small patient cohorts in previous studies hindering the assessment of exposure-response relationships. This multicenter retrospective study aimed to investigate relationships between posaconazole concentration and clinical outcomes and adverse events and to assess clinical factors and drug interactions that may affect posaconazole concentrations. Medical records were reviewed for patients who received posaconazole and had ≥1 concentration measured at six hospitals in Australia. Data from 86 patients with 541 posaconazole concentrations were included in the study. Among 72 patients taking posaconazole for prophylaxis against IFIs, 12 patients (17%) developed a breakthrough fungal infection; median posaconazole concentrations were significantly lower than in those who did not develop fungal infection (median [range], 289 [50 to 471] ng/ml versus 485 [0 to 2,035] ng/ml; P posaconazole concentration was a significant predictor of breakthrough fungal infection via binary logistic regression (P posaconazole exposure, including coadministration with proton pump inhibitors, metoclopramide, phenytoin or rifampin, and the H(2) antagonist ranitidine (P posaconazole exposure (P posaconazole concentrations are common and are associated with breakthrough fungal infection, supporting the utility of monitoring posaconazole concentrations to ensure optimal systemic exposure.

  8. The unique and interactive contributions of peer victimization and teacher-child relationships to children's school adjustment. (United States)

    Troop-Gordon, Wendy; Kuntz, Kayla J


    The present study tested whether a close relationship with the teacher would reduce, or a conflictual relationship would amplify, links between peer victimization and school maladjustment. Data on 352 3rd- and 4th-grade children (166 boys; 186 girls) were collected over a two-year period. Teachers provided data on their relationships with students and students' academic performance. Children completed measures assessing peer victimization and school liking. Latent growth curve analyses revealed that at high levels of peer victimization declines in school liking were reduced when student shared a close, low conflict, relationship with their teacher. Furthermore, a combination of peer victimization and poor teacher-child relationship quality predicted trajectories of sustained, low academic performance. These findings highlight the benefits of a close relationship with the teacher for victimized children and the cumulative impact stress within peer- and teacher-relationships can have on students.

  9. Developing the therapeutic relationship: from 'expert' professional to 'expert' person who stutters. (United States)

    Botterill, Willie


    This article looks back over the years and identifies some of the most influential thinkers, writers, and researchers who have had a profound effect on the way the therapy at the Michael Palin Centre for Stammering Children in London has evolved. It tracks the changes that have occurred in theoretical perspective, treatments offered, and the delivery of therapy. In particular this author is interested in the changing nature of the therapeutic relationship between professionals and people who stutter (PWS), and describes the way it has developed from the "expert professional" towards a more collaborative relationship that recognises the "expert patient". It was inspired by a book written in 1902 by Mr Beasley, a person who stammered. After several unsuccessful attempts to find a 'cure' he found his own solution to his stuttering and then used what he had learned to help many others. Much of what he wrote was well ahead of his time and reminds us, the professionals, of the importance of listening to and taking account of the views of PWS in therapy and designing treatment that meets the needs of the individual. This article also looks briefly at evidence based practice (EBP) and the issues involved in measuring outcomes that reflect the complex and individual nature of the problem. Finally the importance of the research in developing the knowledge and skill base of clinicians as well as PWS is acknowledged and discussed and the way ahead signposted. The reader will learn about (1) the early history and development of stuttering therapy, (2) the influence of a variety of psychotherapeutic approaches, (3) the relevance of designing therapy to meet the needs of the PWS, and (4) discuss the role of 'common' factors in EBP.

  10. Uniqueness of Specific Interfacial Area–Capillary Pressure–Saturation Relationship Under Non-Equilibrium Conditions in Two-Phase Porous Media Flow

    KAUST Repository

    Joekar-Niasar, Vahid


    The capillary pressure-saturation (P c-S w) relationship is one of the central constitutive relationships used in two-phase flow simulations. There are two major concerns regarding this relation. These concerns are partially studied in a hypothetical porous medium using a dynamic pore-network model called DYPOSIT, which has been employed and extended for this study: (a) P c-S w relationship is measured empirically under equilibrium conditions. It is then used in Darcy-based simulations for all dynamic conditions. This is only valid if there is a guarantee that this relationship is unique for a given flow process (drainage or imbibition) independent of dynamic conditions; (b) It is also known that P c-S w relationship is flow process dependent. Depending on drainage and imbibition, different curves can be achieved, which are referred to as "hysteresis". A thermodynamically derived theory (Hassanizadeh and Gray, Water Resour Res 29: 3389-3904, 1993a) suggests that, by introducing a new state variable, called the specific interfacial area (a nw, defined as the ratio of fluid-fluid interfacial area to the total volume of the domain), it is possible to define a unique relation between capillary pressure, saturation, and interfacial area. This study investigates these two aspects of capillary pressure-saturation relationship using a dynamic pore-network model. The simulation results imply that P c-S w relation not only depends on flow process (drainage and imbibition) but also on dynamic conditions for a given flow process. Moreover, this study attempts to obtain the first preliminary insights into the global functionality of capillary pressure-saturation-interfacial area relationship under equilibrium and non-equilibrium conditions and the uniqueness of P c-S w-a nw relationship. © 2012 The Author(s).

  11. The relationship between therapist-client interpersonal compatibility, sex of therapist, and therapeutic outcome. (United States)

    Malloy, T E


    Explored the relationship between therapist-client interpersonal compatibility, sex of therapist, and psychotherapeutic outcome. The research sample consisted of 48 therapist-client dyads. The therapists were all graduate students enrolled in an individual therapy practicum, while the client sample was composed of 48 undergraduate female (mean age 19.3 years). The interpersonal compatibility of the dyads was determined from the FIRO-B results for each of the members' using a modification of Schutz's (1966) original mathematical schema. Therapy outcome was determined from pretherapy and posttherapy testing with the Tennessee Self Concept Scale and Mooney Problem Check List. A 3 X 2 research design with one concomitant variable (pretest) was used and data were analyzed using an analysis of covariance procedure. Results suggested that among this sample the sex of therapist did not have a significant differential effect. There was also a consistent lack of interaction effects between dyadic compatibility and sex of therapist. However, significant differences in therapeutic outcome across the levels of compatibility were observed.

  12. First impressions in complementary practice: the importance of environment, dress and address to the therapeutic relationship. (United States)

    Turner, Roger Newman; Leach, Janine; Robinson, David


    The aim of the study was to explore patients' views of the importance of environmental and social factors within a complementary and alternative medicine (CAM) practice. A cross-sectional patient survey was conducted in 37 CAM practices across nine geographical areas of the UK using a structured questionnaire. The 219 responders (response rate 59%) were 65% female. The most common treatment modalities were osteopathy and acupuncture. Patients rated telephone manner, practitioner appearance and explanatory literature as very important factors in shaping first impressions and influencing their confidence in the complementary practice. Patients' preferences for practitioner dress code were highly variable. Overall 65% preferred a white coat to casual dress. A multivariate analysis revealed that this preference was statistically significantly greater in two geographical regions and in patients over 70 years old. It was not influenced by gender or treatment modality. Further research is recommended in order to understand how the complex verbal and non-verbal communication implicit in the CAM setting may affect the therapeutic relationship.

  13. Review of Dialogues on difference: Studies of diversity in the therapeutic relationship. (United States)

    Consoli, Andrés J


    Reviews the book, Dialogues on difference: Studies of diversity in the therapeutic relationship edited by J. Christopher Muran (see record 2006-11731-000). Muran, the editor and one of the authors of the book being reviewed here, has contributed an excellent tome. The book fastens a time when speaking of psychotherapy and cultural competence will be unnecessary because of its redundancy. Furthermore, Muran has made use of a powerful, extremely relevant yet equally demanding structure to bring this book about: actual, consecutive dialogues between the chapter author(s), the respective two commentators, and the author(s) once again in a rejoinder. The dialogue format requires a significant commitment to the project over time and a systematic follow through for the dialogues to come to fruition. The final product is highly recommended reading for psychotherapy practitioners at all stages of professional development, for psychotherapy researchers seeking important lines of research on psychotherapy process, and for instructors wanting potent illustrations by courageous therapists willing to expose their internal processes.

  14. The relationship between adult attachment style and therapeutic alliance in individual psychotherapy: a meta-analytic review. (United States)

    Diener, Marc J; Monroe, Joel M


    The present study examined the relationship between adult attachment style and therapeutic alliance in individual psychotherapy. Search procedures yielded 17 independent samples (total N = 886, average n = 52, standard deviation = 24) for inclusion in the meta-analysis. Results indicated that greater attachment security was associated with stronger therapeutic alliances, whereas greater attachment insecurity was associated with weaker therapeutic alliances, with an overall weighted effect size of r = .17, p .10) with the exception of the source of alliance ratings; results indicated that patient-rated alliance demonstrated a significantly larger relationship with attachment compared with therapist-rated alliance (Qbetween = 3.95, df = 1, p = .047). Implications for clinical practice and future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved).

  17. The Effect of Using Peplau's Therapeutic Relationship Model on Anxiety of Coronary Artery Bypass Graft Surgery Candidates

    Directory of Open Access Journals (Sweden)



    Full Text Available Background Anxiety is a one of the psychological aftereffect of cardiac surgery, which affects the outcome of treatment. One of the most effective ways to reduce anxiety is to train and establish a targeted relationship based on a functional model. Objectives The present study aimed to determine the effect of Peplau's therapeutic relationship model on anxiety of patients who were candidate for coronary artery bypass graft surgery (CABG. Patients and Methods In this clinical trial, 74 patients were enrolled according to eligibility criteria and were randomly allocated to intervention and control groups of 37 people. We evaluated anxiety of the patients using the Beck anxiety inventory before, immediately after, and two and four months after intervention. Based on Peplau's therapeutic relationship model, therapeutic communication sessions were conducted in four phases during seven sessions. Data analysis was performed with the statistical test of covariance analysis using SPSS version 16. Results The results of our study showed that after therapeutic communication, the mean score of anxiety decreased from 30.35 to 25.38 in the intervention group (P < 0.001, while the scores decreased from 33.22 to 31.46 in the control group. Furthermore, the mean score of anxiety in the intervention group decreased at two and four months after the intervention. Conclusions The findings showed a positive effect of therapeutic relationship based on Peplau's model on reducing anxiety of patients undergoing CABG. Therefore, health care teams, including nurses, should take advantage of appropriate communication with patients in their care procedures. In that regard, Peplau's communication model is recommended as a simple, low-cost, and efficient method.

    Calogero Lo Piccolo


    Full Text Available The paper shows how the therapeutic analytic group tackles the issue of pathological substance addiction, how the focus on intervention has changed in the course of the last years, especially as regards the social transformations which have changed the nature itself of dependence and of the underlying issues. Attention is drawn especially on the therapeutic value of the analytic group, seen as the preferred instrument for the transformative treatment of the issues underlying dependence in the contemporary world.Key words: lifestyles, consumer styles, therapeutic group, pathological dependencies, Trauma of the Future

  1. Narcissism, solitude, friendship: notes on the therapeutic alliance in the context of the Freud-Jung relationship. (United States)

    Carta, Stefano


    This paper deals with friendship and therapeutic alliance as a transformation of the libidinal love that structures the Oedipal complex. The author considers the relationship between Jung and Freud as a formidable test that may shed light on their personalities and on the relevance of the Oedipal complex for both of them and for their particular theories and practices. The author discusses the possibility that the Oedipal complex may be seen under a finalistic frame of reference and discusses which implicit goals it may express. Such a goal has not been reached by either Freud nor Jung, but might be the key to underline and recognize the fundamental importance of the 'therapeutic alliance' within the analytical situation, seen as a potential relationship between the selves of the patient and of the analyst springing from a transformation of libidinal love into 'friendship' as it was described by Friedrich Nietzsche. © 2012, The Society of Analytical Psychology.

  2. Nurses and care workers’ perceptions of their nurse-patient therapeutic relationship in private general hospitals, Gauteng, South Africa

    Directory of Open Access Journals (Sweden)

    Anna E. van den Heever


    Full Text Available Facilitation of a therapeutic relationship is an essential skill in nursing, particularly in mental-health care. Nurses and care workers in private general hospitals are exposed to the emotional effects of physical illness as well as the increase in admission of patients with mental-health needs. Poor nurse-patient relationships have been reported by patients and in the media. The researchers experienced incidents of apparent misunderstandings during nurse-patient interactions whilst working in private general hospitals. No studies have been done regarding how nurses and care workers perceive a therapeutic relationship with patients in terms of the patients’ emotional and mental-health needs. A quantitative, contextual and deductive study was conducted in three private general hospitals in Gauteng, South Africa with a purposive sample of 154 nurses and 30 care workers. Based on the concepts of a therapeutic relationship, empathy, positive regard, genuineness, concreteness and self-exploration, nurses and care workers’ perceptions of facilitating a therapeutic relationship were self-assessed using five-point scales in a questionnaire. Data were analysed using descriptive statistics and non-parametric statistical techniques. Specific hypotheses were tested to identify whether statistically-significant differences existed between the perceptions of two or more groups of nurses and care workers. Results showed a general insensitivity and lack of awareness and reflection on the part of nurses and care workers with regard to the patients’ emotional needs. When categories of nurses were compared, no statistically-significant differences were found between the perceptions of the various groups tested. There is a need for self-awareness, continued interpersonal skills training and supervision of nurses and care workers. A large percentage of the participants were younger than 40 years, subprofessional, with less than 10 years’ experience as

  3. Tele-analysis: the use of media technology in psychotherapy and its impact on the therapeutic relationship. (United States)

    Roesler, Christian


    A growing number of approaches in psychotherapy make use of internet- and other media-based interactions. This paper discusses the impact on the therapist-client relationship of using media technology and gives an overview of the current state of the debate. It is suggested that the technical conditions of internet-based interactions produce new forms of social relationships that differ significantly from face-to-face-interactions and that unconscious, nonverbal cues get lost. Research on the therapeutic interaction making use of 'discourse linguistic' methods is presented. The loss of nonverbal cues has implications for psychotherapy in general and especially for the treatment of patients who have difficulties relying on a secure therapeutic relationship. Emotional security in interactional relationships is transmitted to a much greater extent by nonverbal cues than by verbal content; psychoanalytic methods are specialized to refer to this level of interaction. Two alternative scenarios are discussed based on the psychoanalytic theories of Winnicott and Lacan: the risk of an illusionary, idealized image of the other and the possibility that cyberspace can be used for psychological development as a transitional space. © 2017, The Society of Analytical Psychology.

  4. Shaping effective communication skills and therapeutic relationships at work: the foundation of collaboration. (United States)

    Grover, Susan M


    Effective communication is essential to practice and can result in improved interpersonal relationships at the workplace. Effective communication is shaped by basic techniques such as open-ended questions, listening, empathy, and assertiveness. However, the relationship between effective communication and successful interpersonal relationships is affected by intervening variables. The variables of gender, generation, context, collegiality, cooperation, self-disclosure, and reciprocity can impede or enhance the outcome of quality communication. It is essential for occupational health nurses to qualitatively assess the degree to which each of these concepts affects communication and, in turn, relationships at work.

  5. Posaconazole Exposure-Response Relationship: Evaluating the Utility of Therapeutic Drug Monitoring


    Dolton, Michael J; Ray, John E.; Marriott, Deborah; McLachlan, Andrew J


    Posaconazole has become an important part of the antifungal armamentarium in the prophylaxis and salvage treatment of invasive fungal infections (IFIs). Structurally related to itraconazole, posaconazole displays low oral bioavailability due to poor solubility, with significant drug interactions and gastrointestinal disease also contributing to the generally low posaconazole plasma concentrations observed in patients. While therapeutic drug monitoring (TDM) of plasma concentrations is widely ...

  6. Relationships among client-therapist personality congruence, working alliance, and therapeutic outcome. (United States)

    Taber, Brian J; Leibert, Todd W; Agaskar, Vaibhavee R


    Despite the importance of the working alliance in therapeutic outcome, little is known about the factors associated with its formation. We advance that personality similarity between client and therapist is one such factor pertinent to the working alliance. In this study, personality similarity in 32 client-therapist dyads was examined for its relations to the bond, task, and goal elements of the working alliance (Bordin, 1979, Psychotherapy: Theory, Research, and Practice, 16, 252-260) and therapeutic outcome. Personality similarity was conceptualized using Holland's (1997, Making vocational choices [3rd ed.]) congruence construct. Therapists completed the Self-Directed Search pretreatment and clients completed the Working Alliance Inventory-Short Revised and Self-Directed Search after the third session. Results indicated that (a) client-therapist personality congruence was associated with the bond, (b) bond was associated with task and goal, and (c) task and goal were associated with therapeutic outcome. Congruence was not associated with task, goal, or therapeutic outcome. Holland's theory provides a framework for adapting to clients of varying personality types. By understanding how client-therapist personalities relate to each other in therapy, client-therapist bonds may be more efficiently realized.

  7. Structural and biochemical analysis of a unique phosphatase from Bdellovibrio bacteriovorus reveals its structural and functional relationship with the protein tyrosine phosphatase class of phytase.

    Directory of Open Access Journals (Sweden)

    Robert J Gruninger

    Full Text Available Bdellovibrio bacteriovorus is an unusual δ-proteobacterium that invades and preys on other Gram-negative bacteria and is of potential interest as a whole cell therapeutic against pathogens of man, animals and crops. PTPs (protein tyrosine phosphatases are an important class of enzyme involved in desphosphorylating a variety of substrates, often with implications in cell signaling. The B. bacteriovorus open reading frame Bd1204 is predicted to encode a PTP of unknown function. Bd1204 is both structurally and mechanistically related to the PTP-like phytase (PTPLP class of enzymes and possesses a number of unique properties not observed in any other PTPLPs characterized to date. Bd1204 does not display catalytic activity against some common protein tyrosine phosphatase substrates but is highly specific for hydrolysis of phosphomonoester bonds of inositol hexakisphosphate. The structure reveals that Bd1204 has the smallest and least electropositive active site of all characterized PTPLPs to date yet possesses a unique substrate specificity characterized by a strict preference for inositol hexakisphosphate. These two active site features are believed to be the most significant contributors to the specificity of phytate degrading enzymes. We speculate that Bd1204 may be involved in phosphate acquisition outside of prey.

  8. Teaching communication and therapeutic relationship skills to baccalaureate nursing students: a peer mentorship simulation approach. (United States)

    Miles, Leslie W; Mabey, Linda; Leggett, Sarah; Stansfield, Katie


    The literature on techniques for improving student competency in therapeutic communication and interpersonal skills is limited. A simulation approach to enhance the learning of communication skills was developed to address these issues. Second-semester and senior nursing students participated in videorecorded standardized patient simulations, with senior students portraying the patient. Following simulated interactions, senior students provided feedback to junior students on their use of communication skills and other therapeutic factors. To integrate the learning experience, junior students completed a written assignment, in which they identified effective and noneffective communication; personal strengths and weaknesses; and use of genuineness, empathy, and positive regard. A videorecording of each student interaction gave faculty the opportunity to provide formative feedback to students. Student evaluations have been positive. Themes identified in student evaluations include the impact of seeing oneself, significance of practicing, getting below the surface in communication, and moving from insight to goal setting.

  9. A rational model for maximizing the effects of therapeutic relationship regulation in personality disorders with poor metacognition and over-regulation of affects. (United States)

    Dimaggio, Giancarlo; Carcione, Antonino; Salvatore, Giampaolo; Semerari, Antonio; Nicolò, Giuseppe


    The therapeutic relationship plays a key role in personality disorder (PD) psychotherapy. Some aspects of therapeutic relationship regulation appear important for treatment of PD clients, including those with constricted relational schemas, poor metacognition, and over-regulation of affects described here. AIM.: To propose a rational model for how and when to work on the therapeutic relationship by treating the underlying personality pathology. Formalize a step-by-step procedure for performing operations such as validation of clients' experiences, creating a sense of sharedness, assessing the quality of the therapeutic relationship in order to prevent and repair ruptures in the alliance, self-disclosing by the therapist, and metacommunication on the basis of clients' responses to treatment. We discuss the implications of this model for further research into the PD therapy process. 2010 The British Psychological Society.

  10. The Shadow of Physical Harm? Examining the Unique and Gendered Relationship Between Fear of Murder Versus Fear of Sexual Assault on Fear of Violent Crime. (United States)

    Riggs, Samantha; Cook, Carrie L


    The shadow hypothesis regarding the impact of fear of sexual assault on fear of violent crime suggests that female fear of crime is characterized by concern about sexual assault as a contemporaneous victimization event during a violent crime event. Recent research has found that other types of crime, namely physical assault, may also be feared as a contemporaneous offense. We know of no research that has examined the unique impact of fear of murder versus fear of sexual assault on fear of violent crime. There is also a lack of research that explores how these two types of fear uniquely affect men and women. In addition to gender, we examine factors that have been suggested in previous research to correlate with fear of crime: race, victimization, vicarious victimization, and perceived risk. Through survey methodology, this research examines the unique relationship between both fear of murder and fear of sexual assault and fear of three types of violent crime for men and women. Results suggest differences in how fear of murder and fear of sexual assault are related to fear of other types of violence for men and women. Specifically, fear of murder is important in estimating male fear of robbery and aggravated assault. However, fear of sexual assault is almost as important as fear of murder for men in estimating fear of home invasion. Similarly, for women, fear of sexual assault and fear of murder both are significant factors associated with fear of violent crime, and differences between the levels of significance are marginal. This study is a first to examine whether murder may also be feared as a contemporaneous offense. The results are informative in identifying what drives fear of crime, particularly violent crime, for both men and women. Avenues for future research are discussed.

  11. [Relationships between diabetes mellitus and periodontal disease: current knowledges and therapeutic prospects]. (United States)

    Garofalo, G S


    Diabetes mellitus is a disorder of the endocrine system. An important pathology of dental interest to which the diabetic patient can go encounter, especially if not controlled from the metabolic point of view, is the periodontal disease. The aim of this review is to illustrate the relation between diabetes mellitus and periodontal disease estimating the several therapeutic options on hand in the clinical daily practice. Many studies show an important association between diabetes and the pathogenesis of periodontal disease. Vascular changes caused by hyper-glycemia are associated to the development of periodontal pathogens species. Moreover, diabetics show an exacerbate host response with hyperproduction of inflammatory mediators and polymorphonuclear dysfunction. Diabetics with good metabolic control and patients with good oral hygiene show a reduced risk of periodontitis. In conclusion, diabetes mellitus (of type 1 and type 2) is an important risk factor for periodontitis. Diabetes mellitus determines changes in bacterial population and production of inflammatory mediators, and reduces the efficacy of the host response. Good controlled diabetes do not cause a major risk of periodontitis and improve the results of the periodontal initial therapy and of the eventual surgical therapy. Moreover, periodontal therapy may reduce the request of insulin in diabetics. It is reasonable a reciprocal relation between diabetes and periodontal disease.

  12. Relationships among alexithymia, therapeutic alliance, and psychotherapy outcome in major depressive disorder. (United States)

    Quilty, Lena C; Taylor, Graeme J; McBride, Carolina; Bagby, R Michael


    Previous studies have found that alexithymia predicts process and outcome of psychodynamic psychotherapy across a range of psychiatric disorders. There is preliminary evidence that alexithymia may exert its effects on outcome through the therapist. Other studies have found that alexithymia does not influence outcome of cognitive-behavioral therapy (CBT). The aim of the current study was to investigate the capacity of alexithymia to predict therapist- and patient-rated therapeutic alliance and response to CBT and interpersonal psychotherapy (IPT) for major depressive disorder. A total of 75 adults with major depressive disorder were randomized to receive weekly sessions of manualized individual CBT or IPT for a period of 16 weeks. Pre-treatment alexithymia exhibited a positive direct effect on depression change, and a negative indirect effect on depression change via patient-rated alliance at week 13. There was no mediating role of therapist-rated alliance. Although these findings are preliminary, they suggest that pre-treatment alexithymia has meaningful links to psychotherapy process and outcome, and that nuanced analyses incorporating intervening variables are necessary to elucidate the nature of these links.

  13. Predictive relationships between chronic pain and negative emotions: a 4-month daily process study using Therapeutic Interactive Voice Response (TIVR). (United States)

    Naylor, Magdalena R; Krauthamer, G Michael; Naud, Shelly; Keefe, Francis J; Helzer, John E


    This article examines temporal relationships between negative emotions and pain in a cohort of 33 patients with chronic musculoskeletal pain enrolled in a telephone-based relapse prevention program (Therapeutic Interactive Voice Response [TIVR]), after 11 weeks of group cognitive behavioral therapy (CBT). Patients were asked to make daily reports to the TIVR system for 4 months after CBT. Patients' daily reports were analyzed with path analysis to examine temporal relationships between 3 emotion variables (anger, sadness, and stress) and 2 pain variables (pain and pain control). As expected, same-day correlations were significant between emotion variables and both pain and pain control. The lagged associations revealed unidirectional relationships between pain and next-day emotions: increased pain predicted higher reports of sadness the following day (P pain control predicted decreased sadness and anger the following day (P emotions predicted increased next-day pain. We speculate that CBT treatment followed by the relapse prevention program teaches patients how to modulate negative emotions such that they no longer have a negative impact on next-day pain perception. The clinical implications of our findings are discussed.

  14. Obesity and psoriasis: inflammatory nature of obesity, relationship between psoriasis and obesity, and therapeutic implications. (United States)

    Carrascosa, J M; Rocamora, V; Fernandez-Torres, R M; Jimenez-Puya, R; Moreno, J C; Coll-Puigserver, N; Fonseca, E


    Obesity, particularly abdominal obesity, is currently considered a chronic low-grade inflammatory condition that plays an active role in the development of the pathophysiologic phenomena responsible for metabolic syndrome and cardiovascular disease through the secretion of proinflammatory adipokines and cytokines. In recent years clear genetic, pathogenic, and epidemiologic links have been established between psoriasis and obesity, with important implications for health. The relationship between the 2 conditions is probably bidirectional, with obesity predisposing to psoriasis and psoriasis favoring obesity. Obesity also has important implications in the treatment of psoriasis, such as a greater risk of adverse effects with conventional systemic drugs and reduced efficacy and/or increased cost with biologic agents, for which dosage should be adjusted to the patient's weight.

  15. ["Street" medication in Burkina Faso: local names, social relationships, and alleged therapeutic effects]. (United States)

    Pale, Augustin; Ladner, Joël


    This qualitative assessment, based on discussions and discourse collected in interviews with members of the general population, addresses the popular view of pharmaceutical drugs in Burkina Faso. The main results demonstrate a strong preference for drugs sold in the street and their largely "off-label" uses. These drugs not only treat defined diseases but also generate street discussions, popular images and social relationships that lead to their consumption, sometimes excessive. Furthermore, the links between the legal and illegal street markets, related in part to the legal status of different drugs, also leads to questions about good and bad, true and false. These distinctions, considered as labels, influence the population's behavior and attitude concerning street medication.

  16. Cardiac contractility structure-activity relationship and ligand-receptor interactions; the discovery of unique and novel molecular switches in myosuppressin signaling.

    Full Text Available Peptidergic signaling regulates cardiac contractility; thus, identifying molecular switches, ligand-receptor contacts, and antagonists aids in exploring the underlying mechanisms to influence health. Myosuppressin (MS, a decapeptide, diminishes cardiac contractility and gut motility. Myosuppressin binds to G protein-coupled receptor (GPCR proteins. Two Drosophila melanogaster myosuppressin receptors (DrmMS-Rs exist; however, no mechanism underlying MS-R activation is reported. We predicted DrmMS-Rs contained molecular switches that resembled those of Rhodopsin. Additionally, we believed DrmMS-DrmMS-R1 and DrmMS-DrmMS-R2 interactions would reflect our structure-activity relationship (SAR data. We hypothesized agonist- and antagonist-receptor contacts would differ from one another depending on activity. Lastly, we expected our study to apply to other species; we tested this hypothesis in Rhodnius prolixus, the Chagas disease vector. Searching DrmMS-Rs for molecular switches led to the discovery of a unique ionic lock and a novel 3-6 lock, as well as transmission and tyrosine toggle switches. The DrmMS-DrmMS-R1 and DrmMS-DrmMS-R2 contacts suggested tissue-specific signaling existed, which was in line with our SAR data. We identified R. prolixus (RhpMS-R and discovered it, too, contained the unique myosuppressin ionic lock and novel 3-6 lock found in DrmMS-Rs as well as transmission and tyrosine toggle switches. Further, these motifs were present in red flour beetle, common water flea, honey bee, domestic silkworm, and termite MS-Rs. RhpMS and DrmMS decreased R. prolixus cardiac contractility dose dependently with EC50 values of 140 nM and 50 nM. Based on ligand-receptor contacts, we designed RhpMS analogs believed to be an active core and antagonist; testing on heart confirmed these predictions. The active core docking mimicked RhpMS, however, the antagonist did not. Together, these data were consistent with the unique ionic lock, novel 3-6 lock

  17. The Same Fish: Creating Space for Therapeutic Relationships, Play, and Development in a School for Children with Special Needs. (United States)

    Alston, Richard; Sosland, Rachel; Tuohy, Anne; Weiler, Nori Anna; Zeitlin, Diane


    This paper represents and attempts to describe psychoanalytically informed work applied in a school setting with children with special needs. While many therapists at the Parkside School are trained in analytic techniques and principles, these ideas have not traditionally been applied to children with language-based learning difficulties. Over the years, we have found that analytic ideas such as transference, countertransference, projective identification, containment, and attachment are especially salient to our understanding of these very complex children. Despite being in a school--a nontraditional setting for psychoanalysis--children are seen in individual and group therapy, often more than once a week. We believe that therapeutic relationships and play (sometimes bringing a child to a place of being able to play) are especially mutative with children with language-based learning challenges. Play and relationship provide a holding environment that, over time, allows for the reorganization of a child's often immature developmental capacities into a sense of agency that captures more clearly a child's innate potential. This article includes case studies of children with complex language-based learning difficulties, including autism spectrum disorders.

    We propose a quantitative network description on the function of uniqueness in a competition system. Two statistical parameters, competition ability and uniqueness are defined, and their relationship in ordinary cases is analytically discussed. The competition between Chinese regional universities is taken as an example. The empirical investigation results show that the uniqueness of a university is really important in competition. Also,uniqueness is very helpful in the promotion of the university overall quality.

  19. Anxiety and Depression Symptom Dimensions Demonstrate Unique Relationships with the Startle Reflex in Anticipation of Unpredictable Threat in 8 to 14 Year-Old Girls. (United States)

    Nelson, Brady D; Hajcak, Greg


    There is growing evidence that heightened sensitivity to unpredictability is a core mechanism of anxiety disorders. In adults, multiple anxiety disorders have been associated with a heightened startle reflex in anticipation of unpredictable threat. Child and adolescent anxiety has been linked to an increased startle reflex across baseline, safety, and threat conditions. However, it is unclear whether anxiety in youth is related to the startle reflex as a function of threat predictability. In a sample of 90 8 to 14 year-old girls, the present study examined the association between anxiety symptom dimensions and startle potentiation during a no, predictable, and unpredictable threat task. Depression symptom dimensions were also examined given their high comorbidity with anxiety and mixed relationship with the startle reflex and sensitivity to unpredictability. To assess current symptoms, participants completed the self-report Screen for Child Anxiety Related Emotional Disorders and Children's Depression Inventory. Results indicated that social phobia symptoms were associated with heightened startle potentiation in anticipation of unpredictable threat and attenuated startle potentiation in anticipation of predictable threat. Negative mood and negative self-esteem symptoms were associated with attenuated and heightened startle potentiation in anticipation of unpredictable threat, respectively. All results remained significant after controlling for the other symptom dimensions. The present study provides initial evidence that anxiety and depression symptom dimensions demonstrate unique associations with the startle reflex in anticipation of unpredictable threat in children and adolescents.

  20. ["Being with" the person cared for in a rehabilitation context: a profound, therapeutic and transformative human relationship]. (United States)

    O'Reilly, Louise; Cara, Chantal


    Due to the relational nature of nursing, "being with" the person that is being cared for is an essential phenomenon in the nursing profession. Furthermore, this concept lies at the very core of the philosophy of Caring, which is, according to various authors, the essence of nursing. Using Watson's Human Caring philosophy as the disciplinary perspective, this phenomenological study has explored, with nurses working in rehabilitation (n=17), the meaning of the experience of "being with" the person cared for, as well as the nurses' perception of the contribution of this experience in the rehabilitation of the cared-for person. A total of 51 interviews, three for every participant, were analyzed using the Relational Caring Inquiry phenomenological method developed by Cara (1997). Through data analysis five eidos-themes have emerged; the following four related to the significance of "being with" the cared-for person: the importance of humanistic values at the core of care; the involvement of the nurse and the cared-for person; the reciprocal and relational dimensions of care, and the irreplaceable care experience of contextual complexity. The fifth and last eidos-theme--enhancing the body-soul-spirit harmony of the person cared-for and of the nurse--leads participants to perceive the therapeutic contribution of the experience of "being with" the cared-for person during their rehabilitation process. These results have contributed to the emergence of the meaning of the phenomenon studied: "a deep, therapeutic, and transforming human relationship". All the results lead to innovative implications and suggest possible interventions that can serve as guides to renew the clinical practice of nurses in rehabilitation, as well as the education and research in nursing science.

  1. The relationship between therapeutic alliance and service user satisfaction in mental health inpatient wards and crisis house alternatives: a cross-sectional study.

    Directory of Open Access Journals (Sweden)

    Angela Sweeney

    Full Text Available BACKGROUND: Poor service user experiences are often reported on mental health inpatient wards. Crisis houses are an alternative, but evidence is limited. This paper investigates therapeutic alliances in acute wards and crisis houses, exploring how far stronger therapeutic alliance may underlie greater client satisfaction in crisis houses. METHODS AND FINDINGS: Mixed methods were used. In the quantitative component, 108 crisis house and 247 acute ward service users responded to measures of satisfaction, therapeutic relationships, informal peer support, recovery and negative events experienced during the admission. Linear regressions were conducted to estimate the association between service setting and measures, and to model the factors associated with satisfaction. Qualitative interviews exploring therapeutic alliances were conducted with service users and staff in each setting and analysed thematically. RESULTS: We found that therapeutic alliances, service user satisfaction and informal peer support were greater in crisis houses than on acute wards, whilst self-rated recovery and numbers of negative events were lower. Adjusted multivariable analyses suggest that therapeutic relationships, informal peer support and negative experiences related to staff may be important factors in accounting for greater satisfaction in crisis houses. Qualitative results suggest factors that influence therapeutic alliances include service user perceptions of basic human qualities such as kindness and empathy in staff and, at service level, the extent of loss of liberty and autonomy. CONCLUSIONS AND IMPLICATIONS: We found that service users experience better therapeutic relationships and higher satisfaction in crisis houses compared to acute wards, although we cannot exclude the possibility that differences in service user characteristics contribute to this. This finding provides some support for the expansion of crisis house provision. Further research is needed

    Full Text Available Westernization movement, started in the last period of the Ottoman Empire and continued after the establishment of the Tukish Republic, is a normal result of migration from east to west. However, this process has different characteristics than the other processes of acculturation in Turkish history, because of the internal dynamics. The first one is, Anatolian people encountered with western culture by the Turks who embraced Western culture, not by Europians due to the distance of geographical distance. Therefore the Western cultural forms just barely adopted by the public, and perceived as an imposition for a long time. The second one is the socio-cultural environment in Europe encountered the art students which sent to the west within the framework of the modernization program. The youth who are expected to create an original art language to reflect the rising values of modern Turkey by learning western art, confronted with the art of chaos within the social sructure caused by the capitalism and World War I. in Europe, in the first quarter of 20. century.

    在有关顾客参与的研究中过于强调顾客参与对顾客满意的影响,以及企业对顾客参与结果的影响.但顾客参与的结果不仅取决于顾客外部因素,还取决于独特性需要这样的顾客内部因素.为揭示独特性需要对顾客参与过程的重要性,本文以独特性需要作为调节变量来考察它在顾客参与活动中对顾客价值创造和满意的影响.在此基础上,运用结构方程模型展开实证研究,研究结果表明,顾客参与对顾客价值的创造有显著正向影响;独特性需要对于顾客参与的价值创造结果确实存在着积极的调节作用.针对研究结论,本文提出了相应的管理对策和研究展望.%The current marketing literature emphasizes on the importance of behavioral congruence of customers, but neglects the reality of behavioral non-uniformity. Behavior non-uniformity asserts that customers behave differently because customers are susceptible to unique needs and the influence of other consumers for impulse behaviors. A customer's unique needs are embedded in the consumption process. Depending on the demand for unique needs, customers would exhibit different behaviors and participate in the consumption process, thereby having varying effects on perceived values. In order to reveal the relationships, this paper assesses the moderating effect of a customer's demand for uniqueness on customer value creation and customer satisfaction in the process of customer participation.We first conduct literature review on uniqueness theory to understand the relationships between a customer's uniqueness needs,and customer value creation. The literature review leads us to derive a theoretical model and hypotheses. Empirical data are collected from subjects in the personal development industry. We conduct in-depth interviews with our subjects and apply structural equation methods to test the proposed hypotheses. The research results show that customer participation has

    Synthetic methods in polymer chemistry have evolved tremendously during the last decade. Nowadays more and more attention is devoted to the application of those tools in the development of the next generation of nanomedicines. Nevertheless, poly(ethylene glycol) (PEG) remains the most frequently used polymer for biomedical applications. In this review, we try to summarize recent efforts and developments in controlled polymerisation techniques that may allow alternatives to PEG based systems and can be used to improve the properties of future polymer therapeutics. © 2011 The Royal Society of Chemistry.

    Efforts to identify fluid biomarkers of Parkinson's disease (PD) have intensified in the last decade. As the role of inflammation in PD pathophysiology becomes increasingly recognized, investigators aim to define inflammatory signatures to help elucidate underlying mechanisms of disease pathogenesis and aid in identification of patients with inflammatory endophenotypes that could benefit from immunomodulatory interventions. However, discordant results in the literature and a lack of information regarding the stability of inflammatory factors over a 24-h period have hampered progress. Here, we measured inflammatory proteins in serum and CSF of a small cohort of PD (n = 12) and age-matched healthy control (HC) subjects (n = 6) at 11 time points across 24 h to (1) identify potential diurnal variation, (2) reveal differences in PD vs HC, and (3) to correlate with CSF levels of amyloid β (Aβ) and α-synuclein in an effort to generate data-driven hypotheses regarding candidate biomarkers of PD. Despite significant variability in other factors, a repeated measures two-way analysis of variance by time and disease state for each analyte revealed that serum IFNγ, TNF, and neutrophil gelatinase-associated lipocalin (NGAL) were stable across 24 h and different between HC and PD. Regression analysis revealed that C-reactive protein (CRP) was the only factor with a strong linear relationship between CSF and serum. PD and HC subjects showed significantly different relationships between CSF Aβ proteins and α-synuclein and specific inflammatory factors, and CSF IFNγ and serum IL-8 positively correlated with clinical measures of PD. Finally, linear discriminant analysis revealed that serum TNF and CSF α-synuclein discriminated between PD and HC with a minimum of 82% sensitivity and 83% specificity. Our findings identify a panel of inflammatory factors in serum and CSF that can be reliably measured, distinguish between PD and HC, and monitor inflammation as disease

  9. Altered relationship of plasma triglycerides to HDL cholesterol in patients with HIV/HAART-associated dyslipidemia: further evidence for a unique form of metabolic syndrome in HIV patients. (United States)

    Vu, Catherine N; Ruiz-Esponda, Raul; Yang, Eric; Chang, Evelyn; Gillard, Baiba; Pownall, Henry J; Hoogeveen, Ron C; Coraza, Ivonne; Balasubramanyam, Ashok


    Plasma triglycerides (TG) and HDL-C are inversely related in Metabolic Syndrome (MetS), due to exchange of VLDL-TG for HDL-cholesteryl esters catalyzed by cholesteryl ester transfer protein (CETP). We investigated the relationship of TG to HDL-C in highly-active antiretroviral drug (HAART)-treated HIV patients. Fasting plasma TG and HDL-C levels were compared in 179 hypertriglyceridemic HIV/HAART patients and 71 HIV-negative persons (31 normotriglyceridemic (NL) and 40 hypertriglyceridemic due to type IV hyperlipidemia (HTG)). CETP mass and activity were compared in 19 NL and 87 HIV/HAART subjects. Among the three groups, a plot of HDL-C vs. TG gave similar slopes but significantly different y-intercepts (9.24±0.45, 8.16±0.54, 6.70±0.65, sqrt(HDL-C) for NL, HIV and HTG respectively; P<0.001); this difference persisted after adjusting HDL-C for TG, age, BMI, gender, glucose, CD4 count, viral load and HAART strata (7.18±0.20, 6.20±0.05 and 4.55±0.15 sqrt(HDL-C) for NL, HIV and HTG, respectively, P<0.001). CETP activity was not different between NL and HIV, but CETP mass was significantly higher in HIV (1.47±0.53 compared to 0.93±0.27μg/mL, P<0.0001), hence CETP specific activity was lower in HIV (22.67±13.46 compared to 28.46±8.24nmol/μg/h, P=0.001). Dyslipidemic HIV/HAART patients have a distinctive HDL-C plasma concentration adjusted for TG. The weak inverse relationship between HDL-C and TG is not explained by altered total CETP activity; it could result from a non-CETP-dependent mechanism or a decrease in CETP function due to inhibitors of CETP activity in HIV patients' plasma.

    It is unclear if atrial fibrillation (AF) patients treated with oral vitamin K antagonists (VKAs) must follow a specific diet to avoid interference with anticoagulation. The aim of this study was to assess if Mediterranean diet (Med-Diet) may affect quality of anticoagulation, as expressed by the time in therapeutic range (TTR). A prospective observational study including 553 non-valvular AF patients. Time in therapeutic range was calculated for all patients treated with VKAs, and adherence to Med-Diet was evaluated with a validated nine-item dietary questionnaire. Cardiovascular events (CVEs), such as cardiovascular death and fatal/non-fatal stroke or myocardial infarction, and bleedings were recorded. The median follow-up was 31.6 months. The median number of international normalized ratios for each patient was 63.0 (35.0-98.0) and 38 730 blood samples were analysed. In the whole cohort, the mean TTR was 65.5 ± 17.8%. The mean Med-Diet score was 5.19 ± 1.6, with frequent use of olive oil (90.1%), fruits (88.4%), and vegetables (69.3%) and low meat intake (71.2%). There were no differences among tertiles of Med-Diet score regarding TTR. A multivariable linear regression analysis showed that diabetes (β: -0.105, P = 0.015) and the use of angiotensin converting enzyme inhibitor/angiotensin receptor blockers (β: 0.153, P Med-Diet score (5.2 ± 1.5 vs. 4.4 ± 1.9, P = 0.004). A reduction of CVE was observed for each point of the Med-Diet score (hazard ratio 0.790, P = 0.017). In our cohort of AF patients, Med-Diet is not associated with changes in TTR, and thus can be recommended for AF patients who are taking VKAs.

  11. The Relationship Between Brain Oscillatory Activity and Therapeutic Effectiveness of Transcranial Magnetic Stimulation in the Treatment of Major Depressive Disorder

    Directory of Open Access Journals (Sweden)

    Andrew Francis Leuchter


    Full Text Available Major Depressive Disorder (MDD is marked by disturbances in brain functional connectivity. This connectivity is modulated by rhythmic oscillations of brain electrical activity, which enable coordinated functions across brain regions. Oscillatory activity plays a central role in regulating thinking and memory, mood, cerebral blood flow, and neurotransmitter levels, and restoration of normal oscillatory patterns is associated with effective treatment of MDD. Repetitive Transcranial Magnetic Stimulation (rTMS is a robust treatment for MDD, but the mechanism of action (MOA of its benefits for mood disorders remains incompletely understood. Benefits of rTMS have been tied to enhanced neuroplasticity in specific brain pathways. We summarize here the evidence that rTMS entrains and resets thalamocortical oscillators, normalizes regulation and facilitates reemergence of intrinsic cerebral rhythms, and through this mechanism restores normal brain function. This entrainment and resetting may be a critical step in engendering neuroplastic changes and the antidepressant effects of rTMS. It may be possible to modify the method of rTMS administration to enhance this mechanism of action and achieve better antidepressant effectiveness. We propose that rTMS can be administered: 1 synchronized to a patient’s individual alpha rhythm (IAF, or synchronized rTMS (sTMS; 2 as a low magnetic field strength sinusoidal wave form; and, 3 broadly to multiple brain areas simultaneously. We present here the theory and evidence indicating that these modifications could enhance the therapeutic effectiveness of rTMS for the treatment of MDD.

  12. Relationship Between Time in Therapeutic Range and Comparative Treatment Effect of Rivaroxaban and Warfarin: Results From the ROCKET AF Trial (United States)

    Piccini, Jonathan P.; Hellkamp, Anne S.; Lokhnygina, Yuliya; Patel, Manesh R.; Harrell, Frank E.; Singer, Daniel E.; Becker, Richard C.; Breithardt, Günter; Halperin, Jonathan L.; Hankey, Graeme J.; Berkowitz, Scott D.; Nessel, Christopher C.; Mahaffey, Kenneth W.; Fox, Keith A. A.; Califf, Robert M.


    Background Time in therapeutic range (TTR) is a standard quality measure of the use of warfarin. We assessed the relative effects of rivaroxaban versus warfarin at the level of trial center TTR (cTTR) since such analysis preserves randomized comparisons. Methods and Results TTR was calculated using the Rosendaal method, without exclusion of international normalized ratio (INR) values performed during warfarin initiation. Measurements during warfarin interruptions >7 days were excluded. INRs were performed via standardized finger‐stick point‐of‐care devices at least every 4 weeks. The primary efficacy endpoint (stroke or non‐central nervous system embolism) was examined by quartiles of cTTR and by cTTR as a continuous function. Centers with the highest cTTRs by quartile had lower‐risk patients as reflected by lower CHADS2 scores (P<0.0001) and a lower prevalence of prior stroke or transient ischemic attack (P<0.0001). Sites with higher cTTR were predominantly from North America and Western Europe. The treatment effect of rivaroxaban versus warfarin on the primary endpoint was consistent across a wide range of cTTRs (P value for interaction=0.71). The hazard of major and non‐major clinically relevant bleeding increased with cTTR (P for interaction=0.001), however, the estimated reduction by rivaroxaban compared with warfarin in the hazard of intracranial hemorrhage was preserved across a wide range of threshold cTTR values. Conclusions The treatment effect of rivaroxaban compared with warfarin for the prevention of stroke and systemic embolism is consistent regardless of cTTR. PMID:24755148

  13. Investigating the relationship between nanomaterial hazard and physicochemical properties: Informing the exploitation of nanomaterials within therapeutic and diagnostic applications. (United States)

    Johnston, Helinor; Brown, David; Kermanizadeh, Ali; Gubbins, Eva; Stone, Vicki


    Nanomaterials (NMs) have the potential to improve the treatment and diagnosis of disease as they are suitable candidates for a number of diagnostic and therapeutic applications. On entering the body via a variety of exposure routes, and during their translocation to secondary target sites it is inevitable that NMs interact with biological molecules, such as proteins. These interactions may influence the behaviour and toxicity of NMs following exposure. As the surface of NMs is what interacts with cells and tissues it is necessary to identify the influence of NM surface properties on their toxicity, and determine how this is influenced by the route of exposure, and physico-chemical characteristics of NMs. The term protein corona is used to describe the coating of the NM surface with protein. The protein corona is a dynamic and complex structure whose composition is dictated by the biological medium and the physico-chemical properties of NMs (such as their size, composition, hydrophobicity and charge) as this influences protein binding specificity and affinity. Depending on the route of exposure (e.g. inhalation or injection) NMs will encounter different proteins. We have observed that i) the composition of protein corona of NMs is likely to be dictated by their route of entry, ii) the translocation of NMs to secondary target sites may influence the composition of the protein corona (i.e. they encounter different proteins on their transport in the body) so that the composition of the protein corona evolves over time, iii) the physico-chemical characteristics of NMs dictate the composition of the protein corona, and the toxicity of NMs and iv) NMs can affect secondary target sites that vary according to delivery route and corona composition following exposure. These findings, and evidence from the wider literature has therefore led us to hypothesise that NM toxicity is dictated by the exposure route due to the acquisition of a surface coating (protein corona) that is

    Kagawa, Shoko; Mihara, Kazuo; Nakamura, Akifumi; Nemoto, Kenji; Suzuki, Takeshi; Nagai, Goyo; Kondo, Tsuyoshi


    The relationship between plasma concentrations of lamotrigine and its therapeutic effects was prospectively studied on 34 (9 men and 25 women) inpatients with treatment-resistant depressive disorder during an 8-week treatment of lamotrigine augmentation using an open-study design. The subjects were depressed patients who had already shown insufficient response to at least 3 psychotropics, including antidepressants, mood stabilizers, and atypical antipsychotics. The diagnoses were major depressive disorder (n = 12), bipolar I disorder (n = 7), and bipolar II disorder (n = 15). The final doses of lamotrigine were 100 mg/d for 18 subjects who were not taking valproate and 75 mg/d for 16 subjects taking valproate. Depressive symptoms were evaluated by the Montgomery Åsberg Depression Rating Scale (MADRS) before and after the 8-week treatment. Blood sampling was performed at week 8. Plasma concentrations of lamotrigine were measured by high-performance liquid chromatography. There was a significant linear relationship between the plasma concentrations of lamotrigine and percentage improvements at week 8 (r = 0.418, P 12.7 μmol/L (11/15 versus 4/19, P treatment-resistant depressive disorder.

    Full Text Available Traditional Chinese medicine (TCM still needs more scientific rationale to be proven for it to be accepted further in the West. We are now in the position to propose computational hypotheses for the mode-of-actions (MOAs of 45 TCM therapeutic action (subclasses from in silico target prediction algorithms, whose target was later annotated with Kyoto Encyclopedia of Genes and Genomes pathway, and to discover the relationship between them by generating a hierarchical clustering. The results of 10,749 TCM compounds showed 183 enriched targets and 99 enriched pathways from Estimation Score ≤ 0 and ≥ 5% of compounds/targets in a (subclass. The MOA of a (subclass was established from supporting literature. Overall, the most frequent top three enriched targets/pathways were immune-related targets such as tyrosine-protein phosphatase nonreceptor type 2 (PTPN2 and digestive system such as mineral absorption. We found two major protein families, G-protein coupled receptor (GPCR, and protein kinase family contributed to the diversity of the bioactivity space, while digestive system was consistently annotated pathway motif, which agreed with the important treatment principle of TCM, “the foundation of acquired constitution” that includes spleen and stomach. In short, the TCM (subclasses, in many cases share similar targets/pathways despite having different indications.

    Full Text Available This article discusses the issue of unique therapeutic projects within the mental health services built in the Brazilian psychiatric reform process. Starting from the concepts that have gained strength in both the psychiatric reform as in the collective health, this study proposes that current notions of the therapeutic project still are influenced by biological, psychological or social paradigms that simplify the complexity of the experience suffered by the subjects. Despite therapeutic projects are an essential achievement for the qualification of mental health care, it is still necessary to produce an epistemological rupture in the relationship with mental suffering so that they can achieve the greatest potential for transformation. Therefore, the article suggests that the practice of therapeutic projects should hold discussions with the reality of users life of and their relationships in the territories of existence, to transform the relations of power and knowledge that reproduce the subjects annulment. Thus, it is possible to dialogue with the complexity of the mental suffering experience, producing changes in the scenes that produce it.

  19. Bioinspired Composite Materials: Applications in Diagnostics and Therapeutics (United States)

    Prasad, Alisha; Mahato, Kuldeep; Chandra, Pranjal; Srivastava, Ananya; Joshi, Shrikrishna N.; Maurya, Pawan Kumar


    Evolution-optimized specimens from nature with inimitable properties, and unique structure-function relationships have long served as a source of inspiration for researchers all over the world. For instance, the micro/nanostructured patterns of lotus-leaf and gecko feet helps in self-cleaning, and adhesion, respectively. Such unique properties shown by creatures are results of billions of years of adaptive transformation, that have been mimicked by applying both science and engineering concepts to design bioinspired materials. Various bioinspired composite materials have been developed based on biomimetic principles. This review presents the latest developments in bioinspired materials under various categories with emphasis on diagnostic and therapeutic applications.

  1. NASA's unique networking environment (United States)

    Johnson, Marjory J.


    Networking is an infrastructure technology; it is a tool for NASA to support its space and aeronautics missions. Some of NASA's networking problems are shared by the commercial and/or military communities, and can be solved by working with these communities. However, some of NASA's networking problems are unique and will not be addressed by these other communities. Individual characteristics of NASA's space-mission networking enviroment are examined, the combination of all these characteristics that distinguish NASA's networking systems from either commercial or military systems is explained, and some research areas that are important for NASA to pursue are outlined.

  8. Amygdalar enlargement associated with unique perception. (United States)

    Asari, Tomoki; Konishi, Seiki; Jimura, Koji; Chikazoe, Junichi; Nakamura, Noriko; Miyashita, Yasushi


    Interference by amygdalar activity in perceptual processes has been reported in many previous studies. Consistent with these reports, previous clinical studies have shown amygdalar volume change in multiple types of psychotic disease presenting with unusual perception. However, the relationship between variation in amygdalar volume in the normal population and the tendency toward unusual or unique perception has never been investigated. To address this issue, we defined an index to represent the tendency toward unique perception using ambiguous stimuli: subjects were instructed to state what the figures looked like to them, and "unique responses" were defined depending on the appearance frequency of the same responses in an age- and gender-matched control group. The index was defined as the ratio of unique responses to total responses per subject. We obtained structural brain images and values of the index from sixty-eight normal subjects. Voxel-based morphometry analyses revealed a positive correlation between amygdalar volume and the index. Since previous reports have indicated that unique responses were observed at higher frequency in the artistic population than in the nonartistic normal population, this positive correlation suggests that amygdalar enlargement in the normal population might be related to creative mental activity.

  9. Therapeutic ultrasound

    Energy Technology Data Exchange (ETDEWEB)

    Crum, Lawrence A [Center for Industrial and Medical Ultrasound, 1013 NE 40th Street, University of Washington, Seattle, WA 98105 (United States)


    The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: tissue ablation, acoustocautery, lipoplasty, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, imageguided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

  10. The therapeutic use of the dog in Spain: a review from a historical and cross-cultural perspective of a change in the human-dog relationship. (United States)

    Vallejo, José Ramón; Santos-Fita, Dídac; González, José Antonio


    In Spain, studies about traditional knowledge related to biodiversity have focused on vascular plants. For this reason, our review concentrates on the identification and inventory of zootherapeutic resources, particularly those involving the dog (Canis lupus familiaris Linnaeus, 1758) throughout the twentieth century to the present. A qualitative systematic review in the fields of ethnomedicine, ethnozoology and folklore was made. Automated searches in the most important databases and digital libraries were performed. All related works were examined thoroughly and information was obtained from 55 documentary sources. We have listed a total of 63 remedies to treat and/or prevent 49 human illnesses and conditions. In 20 of the documented reports the whole animal was used and the use of pups was recommended in 12 cases. Saliva was the healing element in 10 remedies, and faeces were the therapeutic basis for nine, while bitch's milk was for seven of them. Skin, fur and meat were next in significance. Currently, healing remedies based on the use of the dog are not part of Spanish ethnomedicine and considering them so would be ahistorical. Indeed, the custom of allowing a dog to lick one's wounds to assist in their healing and cicatrisation has survived in only a few groups of people. However, we can state that the ethnomedical use of the dog exists and has been transferred to "animal-assisted therapy".

  11. Rethinking therapeutic action. (United States)

    Gabbard, Glen O; Westen, Drew


    Like other core psychoanalytic constructs, the theory of therapeutic action is currently in flux, as theorists of differing persuasions propose different mechanisms. In this article, the authors attempt to integrate developments within and without psychoanalysis to provide a working model of the multifaceted processes involved in producing change in psychoanalysis and psychoanalytic psychotherapy. A theory of therapeutic action must describe both what changes (the aims of treatment) and what strategies are likely to be useful in facilitating those changes (technique). The authors believe that single-mechanism theories of therapeutic action, no matter how complex, are unlikely to prove useful at this point because of the variety of targets of change and the variety of methods useful in effecting change in those targets (such as techniques aimed at altering different kinds of conscious and unconscious processes). Interventions that facilitate change may be classified into one of three categories: those that foster insight, those that make use of various mutative aspects of the treatment relationship and a variety of secondary strategies that can be of tremendous importance. They propose that, in all forms of psychoanalytic treatment, we would be more accurate to speak of the therapeutic actions, rather than action.

    Bockman, R.; Adelman, R.; Donnelly, R.; Brody, L.; Warrell, R. (Hospital for Special Surgery, New York, NY (USA)); Jones, K.W. (Brookhaven National Lab., Upton, NY (USA))


    The discovery of gallium as a new and unique agent for the treatment of metabolic bone disorders was in part fortuitous. Gallium is an exciting new therapeutic agent for the treatment of pathologic states characterized by accelerated bone resorption. Compared to other therapeutic metal compounds containing platinum or germanium, gallium affects its antiresorptive action without any evidence of a cytotoxic effect on bone cells. Gallium is unique amongst all therapeutically available antiresorptive agents in that it favors bone formation. 18 refs., 1 fig.

    Full Text Available A lo largo de la trayectoria de la disciplina de Enfermería, la relación persona-enfermera aparece como una constante tanto en la literatura como en las publicaciones científicas. Así, las grandes teóricas de la profesión nos definen Enfermería como una relación que ayuda, que acompaña a la persona, dentro de su entorno, a vivir experiencias de salud. Pero a nivel práctico, la relación terapéutica es escasa; escasez que se agrava en el hospital por la ruptura con el entorno propio.La variable tiempo en el sistema sanitario actual en el que impera la tecnología, el control del coste, la rapidez en el diagnostico y la eficacia del tratamiento, la convierten en un valor oro. En este contexto la relación de la enfermera se resume en una reproducción de estereotipos verbales y no verbales.El objetivo esta revisión es conocer la formación académica del personal de enfermería en materia de relación terapéutica. Tras una revisión bibliográfica exhaustiva de producción española sobre la formación en este campo, se ha llegado a la conclusión de que la relación enfermera-paciente emerge como asignatura pendiente. Una adecuada formación pre y post-graduada son necesarias y demandadas por los profesionales.During the whole evolution of the nursing discipline, the nurse-patient relationship seems to be a constant issue in the literature and in the scientific publications.

  14. Carbohydrates in therapeutics. (United States)

    Kilcoyne, Michelle; Joshi, Lokesh


    Awareness of the importance of carbohydrates in living systems and medicine is growing due to the increasing understanding of their biological and pharmacological relevance. Carbohydrates are ubiquitous and perform a wide array of biological roles. Carbohydrate-based or -modified therapeutics are used extensively in cardiovascular and hematological treatments ranging from inflammatory diseases and anti-thrombotic treatments to wound healing. Heparin is a well-known and widely used example of a carbohydrate-based drug but will not be discussed as it has been extensively reviewed. We will detail carbohydrate-based and -modified therapeutics, both those that are currently marketed or in various stages of clinical trials and those that are potential therapeutics based on promising preclinical investigations. Carbohydrate-based therapeutics include polysaccharide and oligosaccharide anti-inflammatory, anti-coagulant and anti-thrombotic agents from natural and synthetic sources, some as an alternative to heparin and others which were designed based on known structure-functional relationships. Some of these compounds have multiple biological effects, showing anti-adhesive, anti-HIV and anti-arthrithic activities. Small molecules, derivatives or mimetics of complement inhibitors, are detailed for use in limiting ischemia/ reperfusion injuries. Monosaccharides, both natural and synthetic, have been investigated for their in vivo anti-inflammatory and cardioprotective properties. Modification by glycosylation of natural products, or glycosylation-mimicking modification, has a significant effect on the parent molecule including increased plasma half-life and refining or increasing desired functions. It is hoped that this review will highlight the vast therapeutic potential of these natural bioactive molecules.

    Satori, Nadine


    An innovative practice, therapeutic touch has been used for around ten years in the treatment of eating disorders. Delivered by nurse clinicians having received specific training, this approach is based on nursing diagnoses which identify the major symptoms of this pathology. The support is built around the body and its perceptions. Through the helping relationship, it mobilises the patient's resources to favour a relationship of trust, a letting-go, physical, psychological and emotional relaxation, and improves the therapeutic alliance.

    Full Text Available This article analysed the different narratives implied in Philemon by utilising the narrative therapeutic approach, as developed by Epston and White (1990. A dominant narrative (the harsh treatment of slaves in the early Christian environment and a challenging narrative (a more humane conduct of slaves were clearly distinguished. The article showed Paul’s attempt to bridge the gap between these two narratives by using certain pointers, possibly taken from mystery religions and Jesus’ example. In conclusion, the narrative therapeutic approach proved to be a new and unique way of looking at Philemon’s narrative world.

  18. Evaluation of the Therapeutic Properties of Mastoparan- and Sifuvirtide- Derivative Antimicrobial Peptides Using Chemical Structure-Function Relationship - in vivo and in silico Approaches. (United States)

    Avram, Speranta; Mernea, Maria; Borcan, Florin; Mihailescu, Dan


    Antimicrobial peptides, also called body defense peptides, are chemical structures widely distributed across the animal and vegetal kingdoms that have a fundamental role as part of the immune system. These peptides are used against a wide range of pathogens, such as Gram-negative and - positive bacteria, fungi and viruses, etc. Their action spectrum makes them important for the pharmaceutical industry, as they could represent templates for the design of new and more potent structures by using drug design and drug delivery systems. Here we present the antimicrobial activity against Bacillus subtilis (expressed as minimal inhibitory concentration values) for 33 mastoparan analogs and their new derivatives by quantitative structure-activity relationship method (2D, aligned and also non-aligned 3D-QSAR). We establish the contribution to antimicrobial activity of molecular descriptors like hydrophobicity, hydrogen bond donor and steric hindrance, correlated with contributions from the membrane environment (sodium, potassium, chloride ions). Also the studies of HIV-1 fusion inhibitor sifuvirtide and its analogs are presented in context of interaction with lipid structures during fusion and delivery of these drugs.

  3. Injectable hydrogels as unique biomedical materials. (United States)

    Yu, Lin; Ding, Jiandong


    A concentrated fish soup could be gelled in the winter and re-solled upon heating. In contrast, some synthetic copolymers exhibit an inverse sol-gel transition with spontaneous physical gelation upon heating instead of cooling. If the transition in water takes place below the body temperature and the chemicals are biocompatible and biodegradable, such gelling behavior makes the associated physical gels injectable biomaterials with unique applications in drug delivery and tissue engineering etc. Various therapeutic agents or cells can be entrapped in situ and form a depot merely by a syringe injection of their aqueous solutions at target sites with minimal invasiveness and pain. This tutorial review summarizes and comments on this soft matter, especially thermogelling poly(ethylene glycol)-(biodegradable polyester) block copolymers. The main types of injectable hydrogels are also briefly introduced, including both physical gels and chemical gels.

  4. Event Segmentation Ability Uniquely Predicts Event Memory (United States)

    Sargent, Jesse Q.; Zacks, Jeffrey M.; Hambrick, David Z.; Zacks, Rose T.; Kurby, Christopher A.; Bailey, Heather R.; Eisenberg, Michelle L.; Beck, Taylor M.


    Memory for everyday events plays a central role in tasks of daily living, autobiographical memory, and planning. Event memory depends in part on segmenting ongoing activity into meaningful units. This study examined the relationship between event segmentation and memory in a lifespan sample to answer the following question: Is the ability to segment activity into meaningful events a unique predictor of subsequent memory, or is the relationship between event perception and memory accounted for by general cognitive abilities? Two hundred and eight adults ranging from 20 to 79 years old segmented movies of everyday events and attempted to remember the events afterwards. They also completed psychometric ability tests and tests measuring script knowledge for everyday events. Event segmentation and script knowledge both explained unique variance in event memory above and beyond the psychometric measures, and did so as strongly in older as in younger adults. These results suggest that event segmentation is a basic cognitive mechanism, important for memory across the lifespan. PMID:23942350

  8. The Lasso Problem and Uniqueness

    CERN Document Server

    Tibshirani, Ryan J


    The lasso is a popular tool for sparse linear regression, especially for problems in which the number of variables p exceeds the number of observations n. But when p>n, the lasso criterion is not strictly convex, and hence it may not have a unique minimum. An important question is: when is the lasso solution well-defined (unique)? We review results from the literature, which show that if the predictor variables are drawn from a continuous probability distribution, then there is a unique lasso solution with probability one, regardless of the sizes of n and p. We also show that this result extends easily to $\\ell_1$ penalized minimization problems over a wide range of loss functions. A second important question is: how can we deal with the case of non-uniqueness in lasso solutions? In light of the aforementioned result, this case really only arises when some of the predictor variables are discrete, or when some post-processing has been performed on continuous predictor measurements. Though we certainly cannot c...

  9. Uniqueness theorems in linear elasticity

    CERN Document Server

    Knops, Robin John


    The classical result for uniqueness in elasticity theory is due to Kirchhoff. It states that the standard mixed boundary value problem for a homogeneous isotropic linear elastic material in equilibrium and occupying a bounded three-dimensional region of space possesses at most one solution in the classical sense, provided the Lame and shear moduli, A and J1 respectively, obey the inequalities (3 A + 2 J1) > 0 and J1>O. In linear elastodynamics the analogous result, due to Neumann, is that the initial-mixed boundary value problem possesses at most one solution provided the elastic moduli satisfy the same set of inequalities as in Kirchhoffs theorem. Most standard textbooks on the linear theory of elasticity mention only these two classical criteria for uniqueness and neglect altogether the abundant literature which has appeared since the original publications of Kirchhoff. To remedy this deficiency it seems appropriate to attempt a coherent description ofthe various contributions made to the study of uniquenes...

    Di Salvo, Donald N; Park, Joseph; Laing, Faye C


    This case series describes a unique sonographic appearance consisting of numerous microcysts and punctate echogenic foci seen on renal sonograms of 10 adult patients receiving chronic lithium therapy. Clinically, chronic renal insufficiency was present in 6 and nephrogenic diabetes insipidus in 2. Sonography showed numerous microcysts and punctate echogenic foci. Computed tomography in 5 patients confirmed microcysts and microcalcifications, which were fewer in number than on sonography. Magnetic resonance imaging in 2 patients confirmed microcysts in each case. Renal biopsy in 1 patient showed chronic interstitial nephritis, microcysts, and tubular dilatation. The diagnosis of lithium nephropathy should be considered when sonography shows these findings.

    Mucormycosis remains a devastating invasive fungal infection, with high mortality rates even after active management. The disease is being reported at an alarming frequency over the past decades from India. Indian mucormycosis has certain unique features. Rhino-orbito-cerebral presentation associated with uncontrolled diabetes is the predominant characteristic. Isolated renal mucormycosis has emerged as a new clinical entity. Apophysomyces elegans and Rhizopus homothallicus are emerging species in this region and uncommon agents such as Mucor irregularis and Thamnostylum lucknowense are also being reported. This review focuses on these distinct features of mucormycosis observed in India.

    An oral drug delivery system using proteinoid microspheres is discussed with respect to its unique dependence on pH. It has been found that certain drugs such as insulin and heparin can be encapsulated in proteinoid spheres at stomach pH's (1-3). These spheres also dissemble at intestinal pH's (6-7) releasing the drug for absorption. Using this technique low molecular weight heparin and human growth hormone have been orally delivered successfully to several animal species. Future work has been proposed to study the interaction and binding of the specific drugs with synthesized oligopeptides.

  16. Hue discrimination, unique hues and naming. (United States)

    Bachy, Romain; Dias, Jérôme; Alleysson, David; Bonnardel, Valérie


    The hue discrimination curve (HDC) that characterizes performances over the entire hue circle was determined by using sinusoidally modulated spectral power distributions of 1.5 c/300 nm with fixed amplitude and twelve reference phases. To investigate relationship between hue discrimination and appearance, observers further performed a free color naming and unique hue tasks. The HDC consistently displayed two minima and two maxima; discrimination is optimal at the yellow/orange and blue/magenta boundaries and pessimal in green and in the extra-spectral magenta colors. A linear model based on Müller zone theory correctly predicts a periodical profile but with a phase-opponency (minima/maxima at 180° apart) which is inconsistent with the empirical HDC's profile.

  17. Unmanned Aerial Vehicles unique cost estimating requirements (United States)

    Malone, P.; Apgar, H.; Stukes, S.; Sterk, S.

    Unmanned Aerial Vehicles (UAVs), also referred to as drones, are aerial platforms that fly without a human pilot onboard. UAVs are controlled autonomously by a computer in the vehicle or under the remote control of a pilot stationed at a fixed ground location. There are a wide variety of drone shapes, sizes, configurations, complexities, and characteristics. Use of these devices by the Department of Defense (DoD), NASA, civil and commercial organizations continues to grow. UAVs are commonly used for intelligence, surveillance, reconnaissance (ISR). They are also use for combat operations, and civil applications, such as firefighting, non-military security work, surveillance of infrastructure (e.g. pipelines, power lines and country borders). UAVs are often preferred for missions that require sustained persistence (over 4 hours in duration), or are “ too dangerous, dull or dirty” for manned aircraft. Moreover, they can offer significant acquisition and operations cost savings over traditional manned aircraft. Because of these unique characteristics and missions, UAV estimates require some unique estimating methods. This paper describes a framework for estimating UAV systems total ownership cost including hardware components, software design, and operations. The challenge of collecting data, testing the sensitivities of cost drivers, and creating cost estimating relationships (CERs) for each key work breakdown structure (WBS) element is discussed. The autonomous operation of UAVs is especially challenging from a software perspective.

    为了探索工作同盟在咨询过程中的发展模式, 采用 Stiles 等(2004)提出的 4 个变化特征参数(shape-of-change parameters)对30个个案的工作同盟在咨询过程中的发展变化进行描述.聚类分析的结果显示有3类工作同盟的发展模式,分别是线性增长、线性下降和二次增长模式.不过, 3种发展模式、4个变化特征参数及同盟的破裂?修复片段对咨询效果均没有影响.比较咨询效果不同的当事人在工作同盟发展模式上的差异, 发现同一个发展模式对于不同的个案可能有着不同的含义, 咨询师在早期对同盟关系的处理与调控对咨询效果有着重要的影响.%Working alliance in counseling has been a highly attended research area for several decades. Although a positive relationship between working alliance and counseling outcome has been well established, little do we know how working alliance functions in counseling process. Studying the development of working alliance would contribute to this understanding. Some theories have focused on describing developmental patterns of working alliance based on existing research findings, such as the U-shaped model and the rupture-repair episodes model. However, empirical effort has failed to show significant effect of these hypothesized developmental patterns on counseling outcomes. This naturalistic study aimed at exploring the developmental patterns of working alliance as emerged in counseling sessions and examining the relationship between these patterns and therapeutic outcomes. The participants included 30 clients from 4 university counseling centers, 10 males and 20 females, with the number of sessions ranging from 4 to11,M = 6.53,SD = 2.03,Mdn = 6. By the time of data collection, all of the clients had finished their therapies. There were 20 therapists in the study, 3 males and 17 females, with professional experience from 1 to 22 years. They rated their therapeutic orientations using a 5

    While the market potentials and impacts of web-based e-commerce are still in the ascendant, the advances in wireless technologies and mobile networks have brought about a new business opportunity and research attention, what is termed mobile commerce. Commonly, mobile commerce is considered to be another new application of existing web-based e-commerce onto wireless networks, but as an independent business area, mobile commerce has its own advantages and challenges as opposed to traditional e-commerce applications. This paper focuses on exploring the unique features of mobile commerce as. Compared with traditional e-commerce. Also, there are still some limitations arisen in m-commerce in contrast to web-based e-commerce. Finally, current state of mobile commerce in Japan is presented in brief, with an introduction of several cases involving mobile commerce applications in today 's marketplace.

  20. Unique features of space reactors (United States)

    Buden, David

    Space reactors are designed to meet a unique set of requirements; they must be sufficiently compact to be launched in a rocket to their operational location, operate for many years without maintenance and servicing, operate in extreme environments, and reject heat by radiation to space. To meet these restrictions, operating temperatures are much greater than in terrestrial power plants, and the reactors tend to have a fast neutron spectrum. Currently, a new generation of space reactor power plants is being developed. The major effort is in the SP-100 program, where the power plant is being designed for seven years of full power, and no maintenance operation at a reactor outlet operating temperature of 1350 K.

  1. The probabilities of unique events.

    Directory of Open Access Journals (Sweden)

    Sangeet S Khemlani

    Full Text Available Many theorists argue that the probabilities of unique events, even real possibilities such as President Obama's re-election, are meaningless. As a consequence, psychologists have seldom investigated them. We propose a new theory (implemented in a computer program in which such estimates depend on an intuitive non-numerical system capable only of simple procedures, and a deliberative system that maps intuitions into numbers. The theory predicts that estimates of the probabilities of conjunctions should often tend to split the difference between the probabilities of the two conjuncts. We report two experiments showing that individuals commit such violations of the probability calculus, and corroborating other predictions of the theory, e.g., individuals err in the same way even when they make non-numerical verbal estimates, such as that an event is highly improbable.

  2. The Evolution of Human Uniqueness. (United States)

    Boyd, Robert


    The human species is an outlier in the natural world. Two million years ago our ancestors were a slightly odd apes. Now we occupy the largest ecological and geographical range of any species, have larger biomass, and process more energy. Usually, this transformation is explained in terms of cognitive ability-people are just smarter than all the rest. In this paper I argue that culture, our ability to learn from each other, and cooperation, our ability to make common cause with large groups of unrelated individuals are the real roots of human uniqueness, and sketch an evolutionary account of how these crucial abilities co-evolved with each other and with other features of our life histories.

  3. CYP1B1: a unique gene with unique characteristics. (United States)

    Faiq, Muneeb A; Dada, Rima; Sharma, Reetika; Saluja, Daman; Dada, Tanuj


    CYP1B1, a recently described dioxin inducible oxidoreductase, is a member of the cytochrome P450 superfamily involved in the metabolism of estradiol, retinol, benzo[a]pyrene, tamoxifen, melatonin, sterols etc. It plays important roles in numerous physiological processes and is expressed at mRNA level in many tissues and anatomical compartments. CYP1B1 has been implicated in scores of disorders. Analyses of the recent studies suggest that CYP1B1 can serve as a universal/ideal cancer marker and a candidate gene for predictive diagnosis. There is plethora of literature available about certain aspects of CYP1B1 that have not been interpreted, discussed and philosophized upon. The present analysis examines CYP1B1 as a peculiar gene with certain distinctive characteristics like the uniqueness in its chromosomal location, gene structure and organization, involvement in developmentally important disorders, tissue specific, not only expression, but splicing, potential as a universal cancer marker due to its involvement in key aspects of cellular metabolism, use in diagnosis and predictive diagnosis of various diseases and the importance and function of CYP1B1 mRNA in addition to the regular translation. Also CYP1B1 is very difficult to express in heterologous expression systems, thereby, halting its functional studies. Here we review and analyze these exceptional and startling characteristics of CYP1B1 with inputs from our own experiences in order to get a better insight into its molecular biology in health and disease. This may help to further understand the etiopathomechanistic aspects of CYP1B1 mediated diseases paving way for better research strategies and improved clinical management.

  4. Conotoxins: Therapeutic Potential and Application

    Directory of Open Access Journals (Sweden)

    Richard T. Layer


    Full Text Available The pharmacological variety of conotoxins, diverse peptides found in the venoms of marine cone snails, is well recognized. Venoms from each of the estimated 500 species of cone snails contain 50 to 200 distinct biologically active peptides. Most conotoxins characterized to date target receptors and ion channels of excitable tissues, such as ligandgated nicotinic acetylcholine, N-methyl-D-aspartate, and type 3 serotonin receptors, as well as voltage-gated calcium, sodium, and potassium channels, and G-protein-coupled receptors including α-adrenergic, neurotensin, and vasopressin receptors, and the norepinephrine transporter. Several conotoxins have shown promise in preclinical models of pain, convulsive disorders, stroke, neuromuscular block, and cardioprotection. The pharmacological selectivity of the conotoxins, coupled with the safety and efficacy demonstrated in preclinical models, has led to their investigation as human therapeutic agents. In the following review, we will survey the pharmacology and therapeutic rationale of those conotoxins with potential clinical application, and discuss the unique challenges that each will face in the course of their transition from venom component to human therapeutic.

    Taniya Mandal


    Full Text Available In this paper we discuss the uniqueness of supersymmetric attractors in four-dimensional N=2 supergravity theories coupled to n vector multiplets. We prove that for a given charge configuration the supersymmetry preserving axion free attractors are unique. We generalise the analysis to axionic attractors and state the conditions for uniqueness explicitly. We consider the example of a two-parameter model and find all solutions to the supersymmetric attractor equations and discuss their uniqueness.

  9. [Therapeutic drug monitoring of rufinamide]. (United States)

    Bentué-Ferrer, Danièle; Tribut, Olivier; Verdier, Marie-Clémence


    Rufinamide is a third-generation antiepileptic drug, available since early 2010 in France. It is indicated in combination therapy in the Lennox-Gastaut syndrome from the age of 4. It has orphan drug status. The bioavailability of rufinamide is high, but decreases with the dose and increases with food intake. Rufinamide is not metabolized by cytochromes but hydrolyzed by a carboxylesterase in an inactive carboxylic derivative. Elimination is mainly renal. The half-life varies from 6 to 10h. Although established from relatively few studies, exposure efficacy and exposure toxicity relationships are argued. A plasma concentration of 15 mg/L, obtained with a standard regimen, reduces the number of seizures of 25%. Few factors of intrinsic variability are described. There are few clinically significant pharmacokinetic interactions and they concern combinations with other antiepileptic drugs, especially valproate. Although there is no validated therapeutic range, the level of evidence for this therapeutic drug monitoring has been estimated at "possibly useful".

  10. [Concept of the therapeutic community]. (United States)

    Eichhorn, H


    The historic development of therapeutic communities is discussed, and it is shown that the term has been neither conceptualized not operationalized. Their unclear aims are considered to be utopian, and the author stresses that previous studies on such communities have been too superficial. The following problems have not hitherto received attention: 1. micro- and macrosocial relationships, 2. the role of the supervisor (authority problems), 3. norms and valuation systems, 4. discipline and sanctions, 5. the problem of roles, 6. questions of indicants and efficacy. The introduction of therapeutic communities is superfluous as a means of improving the socialist health services: it is sufficient to implement the principles of socialist democracy by means of appropriate training programmes.

  11. [Therapeutic drug monitoring of stiripentol]. (United States)

    Verdier, Marie-Clémence; Tribut, Olivier; Bentué-Ferrer, Danièle


    Stiripentol is a third generation antiepileptic, marketed since 2007 under the name of Diacomit(®). It is indicated, always in combination, in the treatment of severe myoclonic epilepsy in infancy or Dravet syndrome. Its pharmacokinetics is not linear. It is a potent inhibitor of CYP3A4, 1A2 and 2C19 and increases the plasma concentrations of many other antiepileptic drugs. Without this being considered as a validated therapeutic range, the trough plasma concentrations at steady-state, corresponding to the usual doses are between 10 and 15 mg/L. The concentration-efficacy relationship is not established, but there is some evidence for a concentration-related toxicity. However, because of its non-linear kinetics, stiripentol should be a good candidate for therapeutic drug monitoring (TDM). Nonetheless, the current level of evidence for the advantage of TDM is "remains to be estimated".

  12. Oncolytic Viruses: Therapeutics With an Identity Crisis. (United States)

    Breitbach, Caroline J; Lichty, Brian D; Bell, John C


    Oncolytic viruses (OV) are replicating viral therapeutics for the treatment of cancer and have been in laboratory development for about twenty years. Recently, the FDA approved Imlygic, a herpes virus based therapeutic for the treatment of melanoma and thus OVs have entered a new era where they are a weapon in the armament of the oncologist. OVs are unique therapeutics with multiple mechanisms of therapeutic activity. The exact path for their development and eventual uptake by pharmaceutical companies is somewhat clouded by an uncertain identity. Are they vaccines, tumour lysing therapeutics, inducers of innate immunity, gene therapy vectors, anti-vascular agents or all of the above? Should they be developed as stand-alone loco-regional therapeutics, systemically delivered tumour hunters or immune modulators best tested as combination therapeutics? We summarize data here supporting the idea, depending upon the virus, that OVs can be any or all of these things. Pursuing a "one-size fits all" approach is counter-productive to their clinical development and instead as a field we should build on the strengths of individual virus platforms.

  14. Bioengineering Beige Adipose Tissue Therapeutics. (United States)

    Tharp, Kevin M; Stahl, Andreas


    Unlocking the therapeutic potential of brown/beige adipose tissue requires technological advancements that enable the controlled expansion of this uniquely thermogenic tissue. Transplantation of brown fat in small animal model systems has confirmed the expectation that brown fat expansion could possibly provide a novel therapeutic to combat obesity and related disorders. Expansion and/or stimulation of uncoupling protein-1 (UCP1)-positive adipose tissues have repeatedly demonstrated physiologically beneficial reductions in circulating glucose and lipids. The recent discovery that brown adipose tissue (BAT)-derived secreted factors positively alter whole body metabolism further expands potential benefits of brown or beige/brite adipose expansion. Unfortunately, there are no sources of transplantable BATs for human therapeutic purposes at this time. Recent developments in bioengineering, including novel hyaluronic acid-based hydrogels, have enabled non-immunogenic, functional tissue allografts that can be used to generate large quantities of UCP1-positive adipose tissue. These sophisticated tissue-engineering systems have provided the methodology to develop metabolically active brown or beige/brite adipose tissue implants with the potential to be used as a metabolic therapy. Unlike the pharmacological browning of white adipose depots, implantation of bioengineered UCP1-positive adipose tissues offers a spatially controlled therapeutic. Moving forward, new insights into the mechanisms by which extracellular cues govern stem-cell differentiation and progenitor cell recruitment may enable cell-free matrix implant approaches, which generate a niche sufficient to recruit white adipose tissue-derived stem cells and support their differentiation into functional beige/brite adipose tissues. This review summarizes clinically relevant discoveries in tissue-engineering and biology leading toward the recent development of biomaterial supported beige adipose tissue implants and

    Human malignant melanoma is a highly aggressive skin tumor that is characterized by its extraordinary heterogeneity, propensity for dissemination to distant organs and resistance to cytotoxic agents. Although chemo- and immune-based therapies have been evaluated in clinical trials, most of these therapeutics do not show significant benefit for patients with advanced disease. Treatment failure in melanoma patients is attributed mainly to the development of tumor heterogeneity resulting from the formation of genetically divergent subpopulations. These subpopulations are composed of cancer stem-like cells (CSCs) as a small fraction and non-cancer stem cells that form the majority of the tumor mass. In recent years, CSCs gained more attention and suggested as valuable experimental model system for tumor study. In melanoma, intratumoral heterogeneity, progression and drug resistance result from the unique characteristics of melanoma stem cells (MSCs). These MSCs are characterized by their distinct protein signature and tumor growth-driving pathways, whose activation is mediated by driver mutation-dependent signal. The molecular features of MSCs are either in a causal or consequential relationship to melanoma progression, drug resistance and relapse. Here, we review the current scientific evidence that supports CSC hypothesis and the validity of MSCs-dependent pathways and their key molecules as potential therapeutic target for melanoma treatment.

  16. Development of lutetium-labeled bombesin derivates: relationship between structure and diagnostic-therapeutic activity for prostate tumor; Desenvolvimento de derivados da bombesina radiomarcados com lutecio-177: relacao estrutura e potencial diagnostico-terapeutico para tumor de prostata

    Energy Technology Data Exchange (ETDEWEB)

    Pujatti, Priscilla Brunelli


    Bombesin (BBN) receptors - in particular, the gastrin-releasing peptide (GRP) receptor peptide - have been shown to be massively over expressed in several human tumors types, including prostate cancer, and could be an alternative as target for its treatment by radionuclide therapy (RNT). A large number of BBN analogs had already been synthesized for this purpose and have shown to reduce tumor growth in mice. Nevertheless, most of the studied analogs exhibit high abdominal accumulation, especially in pancreas. This abdominal accumulation may represent a problem in clinical use of radiolabeled bombesin analogs probably due to serious side effects to patients. The goal of the present work was to radiolabel a novel series of bombesin derivatives with lutetium-177 and to evaluate the relationship between their structure and diagnostic-therapeutic activity for prostate tumor. The generic structure of studied peptides is DOTA-Phe-(Gly){sub n}-BBN(6-14), where DOTA is the chelator, n is the number of glycine amino acids of Phe-(Gly){sub n} spacer and BBN(6-14) is the bombesin sequence from the amino acid 6 to the amino acid 14. Preliminary studies were done to establish the ideal labeling conditions for obtaining the highest yield of labeled bombesin derivatives, determined by instant thin layer chromatography (ITLC-SG) and high performance liquid chromatography (HPLC). The stability of the preparations was evaluated either after storing at 2-8 degree C or incubation in human serum at 37 degree C and the partition coefficient was determined in n:octanol:water. In vivo studies were performed in both healthy Balb-c and Nude mice bearing PC-3 xenografts, in order to characterize the biological properties of labeled peptides. In vitro studies involved the evaluation of cold bombesin derivatives effect in PC-3 cells proliferation. Bombesin derivatives were successfully labeled with high yield at optimized conditions and exhibited high stability at 4 degree C. The analysis of

    Institute of Scientific and Technical Information of China (English)

    Michael J. Quon


    Endothelial dysfunction contributes to cardiovascular diseases that are also characterized by insulin resistance. Insulin resistance is a hallmark of metabolic disorders including Type 2 diabetes, obesity, and the metabolic syndrome that are also characterized by endothelial dysfunction. Metabolic actions of insulin to promote glucose disposal are augmented by vascular actions of insulin in endothelium to stimulate production of the vasodilator nitric oxide (NO). Indeed, NO-dependent increases in blood flow to skeletal muscle account for 25% to 40% of the increase in glucose uptake in response to insulin stimulation. PI 3-kinase-dependent insulin signaling pathways in endothelium related to production of NO share striking similarities with metabolic pathways in skeletal muscle that promote glucose uptake. Other distinct non-metabolic branches of insulin signaling pathways regulate secretion of the vasoconstrictor endothelin-1 (ET-1) in endothelium. Metabolic insulin resistance is characterized by pathway-specific impairment in PI 3-kinase-dependent signaling that in endothelium may cause imbalance between production of NO and secretion of ET-1 leading to decreased blood flow that worsens insulin resistance. Therapeutic interventions in both animal models and human studies demonstrate that improving endothelial function ameliorates insulin resistance while improving insulin sensitivity ameliorates endothelial dysfunction. Taken together, cellular, physiological, clinical, and epidemiological studies strongly support a reciprocal relationship between endothelial dysfunction and insulin resistance that helps to link cardiovascular and metabolic diseases. In this review, pathophysiological mechanisms that couple endothelial dysfunction with insulin resistance will be discussed with an emphasis on important therapeutic implications for the metabolic syndrome.%内皮功能障碍可导致兼具胰岛素抵抗特征的心血管疾病.胰岛素抵抗是2型糖尿病、肥

    Robert M. Caliva; James A. Murphy; Kyle B. Oswald


    The Idaho National Laboratory (INL) is a science-based, applied engineering laboratory dedicated to supporting U.S. Department of Energy missions in nuclear and energy research, science, and national security. The INL’s Systems Engineering organization supports all of the various programs under this wide array of missions. As with any multifaceted organization, strategic planning is essential to establishing a consistent culture and a value discipline throughout all levels of the enterprise. While an organization can pursue operational excellence, product leadership or customer intimacy, it is extremely difficult to excel or achieve best-in-class at all three. In fact, trying to do so has resulted in the demise of a number of organizations given the very intricate balancing act that is necessary. The INL’s Systems Engineering Department has chosen to focus on customer intimacy where the customer’s needs are first and foremost and a more total solution is the goal. Frequently a total solution requires the employment of specialized tools to manage system complexity. However, it is only after understanding customer needs that tool selection and use would be pursued. This results in using both commercial-off-the-shelf (COTS) tools and, in some cases, requires internal development of specialized tools. This paper describes how a unique systems engineering capability, through the development of customized tools, evolved as a result of this customer-focused culture. It also addresses the need for a common information model or analysis framework and presents an overview of the tools developed to manage and display relationships between entities, support trade studies through the application of utility theory, and facilitate the development of a technology roadmap to manage system risk and uncertainty.

  2. Therapeutic working alliance: From a psychoanalitical to a pantheoretical conception

    Peter Praper


    Full Text Available Although the concept of therapeutic working alliance was rooted in psychoanalysis, today it is more prominent in psychoanalytic psychotherapies than psychoanalysis. It is rather surprising that we cannot find the concept in the Laplanche and Pontalis Dictionary. During the last two decades a growing body of empirical research material on therapeutic working alliance was published, confirming the idea of the alliance as a separate dimension of therapeutic relationship with few recognisable components. The dimension of the therapeutic working alliance was examined in several approaches and proved as one of the most important therapeutic factors, regardless of the approach, and it has finally been accepted as a pantheoretical concept.

    Hydrogen sulfide (H2S) has become recognized as an important signalling molecule throughout the body, contributing to many physiological and pathological processes. In recent years, improved methods for measuring H2S levels and the availability of a wider range of H2S donors and more selective inhibitors of H2S synthesis have helped to more accurately identify the many biological effects of this highly reactive gaseous mediator. Animal studies of several H2S-releasing drugs have demonstrated considerable promise for the safe treatment of a wide range of disorders. Several such drugs are now in clinical trials.

    Full Text Available The concept of utilizing polymers in drug delivery has been extensively explored for improving the therapeutic index of small molecule drugs. In general, polymers can be used as polymer-drug conjugates or polymeric micelles. Each unique application mandates its own chemistry and controlled release of active drugs. Each polymer exhibits its own intrinsic issues providing the advantage of flexibility. However, none have as yet been approved by the U.S. Food and Drug Administration. General aspects of polymer and nano-particle therapeutics have been reviewed. Here we focus this review on specific clinically relevant anticancer polymer paclitaxel therapeutics. We emphasize their chemistry and formulation, in vitro activity on some human cancer cell lines, plasma pharmacokinetics and tumor accumulation, in vivo efficacy, and clinical outcomes. Furthermore, we include a short review of our recent developments of a novel poly(L-g-glutamylglutamine-paclitaxel nano-conjugate (PGG-PTX. PGG-PTX has its own unique property of forming nano-particles. It has also been shown to possess a favorable profile of pharmacokinetics and to exhibit efficacious potency.

    DEFF Research Database (Denmark)

    Smith, Anton Allen Abbotsford


    The field of drug delivery is in essence an exercise in engineered pharmacokinetics. Methods of doing so have been developed through the introduction of a vehicle carrying the drug, either by encapsulation or covalent attachment. The emergence of polymer therapeutics in anticancer therapy has...... the examples of polymer therapeutics being applied as an antiviral treatment are few and far in-between. This work aims to explore antiviral therapeutics, specifically in context of hepatitis virus C (HCV) and HIV. The current treatment of hepatitis C consists of a combination of drugs, of which ribavirin....... Curiously, the therapeutic window of ribavirin was vastly improved in several of these polymers suggesting altered pharmacodynamics. The applicability of liver-targeting sugar moieties is likewise tested in a similarly methodical approach. The same technique of synthesis was applied with zidovudine to make...

  16. An attachment perspective on therapeutic processes and outcomes. (United States)

    Mikulincer, Mario; Shaver, Phillip R; Berant, Ety


    Over the past decade, there has been an explosion of interest in clinical applications of attachment theory. In the present article, we briefly describe John Bowlby's model of therapeutic change, the therapeutic relationship, and the therapist's role in emotional healing. We then review empirical evidence for three key propositions in Bowlby's model. First, a client's sense of security during therapy is crucial for facilitating therapeutic work. Second, a therapist's own sense of security contributes to positive therapeutic outcomes. Third, attachment insecurities can be effectively reduced in therapy, and movement toward greater attachment security is central to achieving favorable therapeutic outcomes. In sum, research evidence confirms the importance of establishing what Bowlby called a safe haven and a secure base within a therapeutic relationship.

  17. Tracing therapeutic discourse in material culture. (United States)

    Parker, I


    Approaches to language and subjectivity from post-structuralist theory outside psychology and from deconstructive perspectives within counselling and psychotherapy have questioned the way therapeutic relationships are formed in Western culture. Discourse analysis has been developed as a methodological framework to take this questioning further, and to provide detailed readings of therapeutic patterns of meaning. Foucauldian discourse analytic approaches help us to address how we are made into selves that speak, how we experience the self therapeutically. I will elaborate this methodological framework through an analysis of a piece of text--an item of consumer packaging--tracing the contours of therapeutic discourse through a series of 20 methodological steps. Therapeutic discourse draws the reader in as the kind of subject who must feel a relationship at some depth with the (imagined) authors for the text to work. This paper thus illustrates the value of discourse analytic readings of texts, and helps us to reflect upon our commitment to discourses of counselling and psychotherapy as empowering stories and as culturally-specific patterns of subjectivity.

  18. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Directory of Open Access Journals (Sweden)

    Joeli A. Brinkman


    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

  2. Right temporopolar activation associated with unique perception. (United States)

    Asari, Tomoki; Konishi, Seiki; Jimura, Koji; Chikazoe, Junichi; Nakamura, Noriko; Miyashita, Yasushi


    Unique mode of perception, or the ability to see things differently from others, is one of the psychological resources required for creative mental activities. Behavioral studies using ambiguous visual stimuli have successfully induced diverse responses from subjects, and the unique responses defined in this paradigm were observed in higher frequency in the artistic population as compared to the nonartistic population. However, the neural substrates that underlie such unique perception have yet to be investigated. In the present study, ten ambiguous figures were used as stimuli. The subjects were instructed to say what the figures looked like during functional MRI scanning. The responses were classified as "frequent", "infrequent" or "unique" responses based on the appearance frequency of the same response in an independent age- and gender-matched control group. An event-related analysis contrasting unique vs. frequent responses revealed the greatest activation in the right temporal pole, which survived a whole brain multiple comparison. An alternative parametric modulation analysis was also performed to show that potentially confounding perceptual effects deriving from differences in visual stimuli make no significant contribution to this temporopolar activation. Previous neuroimaging and neuropsychological studies have shown the involvement of the temporal pole in perception-emotion linkage. Thus, our results suggest that unique perception is produced by the integration of perceptual and emotional processes, and this integration might underlie essential parts of creative mental activities.

  3. [Therapeutic drug monitoring of clobazam]. (United States)

    Bentué-Ferrer, Danièle; Tribut, Olivier; Verdier, Marie-Clémence; Debruyne, Danièle


    Clobazam is a 1,5 benzodiazepine available in France since 1975, used in add-on with the other anticonvulsant drugs in the treatment of refractory epilepsies of child and adult and for the treatment of anxiety of adult. It is mainly metabolized in desmethylclobazam, or norclobazam, active metabolite, present in a concentration approximately eight times superior to that of the parent drug, but with an activity of the order of 20 to 40% of that of clobazam. Elimination half-life of clobazam is of 18 h while that of norclobazam is from 40 to 50 h. There is a large interindividual variability in the plasma concentrations. Furthermore, clobazam being prescribed in add-on with the other anticonvulsant drugs in resistant epilepsies, concentration-effect relationship is difficult to bring to light, since, in many studies, the patients who did not answer received the highest doses. Adverse reactions are moderated, appearing more often for the highest concentrations; also the phenomenon of tolerance seems more frequent in high concentrations. However, because of the kinetic interactions, a dosage of clobazam and norclobazam can be useful in certain cases. There is no validated therapeutic range, but the usual concentrations are in the range of 100-300 microg/L for the parent drug and about ten times more for the metabolite. The level of proof of the interest of the Therapeutic Drug Monitoring for this molecule is estimated in: rather useless.

  4. Lymphedema and Therapeutic Lymphangiogenesis

    Directory of Open Access Journals (Sweden)

    Yukihiro Saito


    Full Text Available Lymphedema is a disorder of the lymphatic vascular system characterized by impaired lymphatic return and swelling of the extremities. Lymphedema is divided into primary and secondary forms based on the underlying etiology. Despite substantial advances in both surgical and conservative techniques, therapeutic options for the management of lymphedema are limited. Although rarely lethal, lymphedema is a disfiguring and disabling condition with an associated decrease in the quality of life. The recent impressive expansion of knowledge on the molecular mechanisms governing lymphangiogenesis provides new possibilities for the treatment of lymphedema. This review highlights the lymphatic biology, the pathophysiology of lymphedema, and the therapeutic lymphangiogenesis using hepatocyte growth factor.

  5. Pancreatic Pseudocyst: Therapeutic Dilemma

    Directory of Open Access Journals (Sweden)

    A. K. Khanna


    Full Text Available Pancreatic pseudocyst develops in both acute and chronic pancreatitis. It is an entity likely to either remain asymptomatic or develop devastating complications. Despite being diagnosed easily, treatment exercise is still at crossroads whether in the form of internal or external drainage or endoscopic, laparoscopic, or open intervention with a good radiological guidance. The therapeutic dilemma whether to treat a patient with a pancreatic pseudocyst, as well as when and with what technique, is a difficult one. This paper is intended to get information about diagnostic and therapeutic exercises most appropriate for acute and chronic pancreatic pseudocyst.

  7. [In the beginning was a relationship]. (United States)

    Vanbelle, Guido


    Judgment and actions based on scientific evidence are modified by the unique caregiver-patient relationship. Caregivers relying exclusively upon "rational" decisions in line with evidence-based clinical recommendations avoid their relational responsibility. The "noble" purpose illustrates that decisions to treat can be at the same time pointless and valuable. Dia (through) - logue (knowledge) makes it possible to go beyond informed consent, which holds caregivers responsible for providing information and patients for the decision to treat. Finally, where healing is no longer achievable and autonomy dies away, compassion rather than therapeutic tenacity might be the answer. These examples are explained corresponding to the philosophical ideas of respectively Emmanuel Levinas en Roger Burgraeve (noble purpose), Martin Buber (dialogical thinking) and Daniel C. Dennett (autonomy loss).

  12. Fairy tales as a trance experience: possible therapeutic uses. (United States)

    Stevens-Guille, M E; Boersma, F J


    The psychological literature contains little documentation of the therapeutic use of fairy tales. We suggest that fairy tales are uniquely suitable for hypnotherapy and for helping clients reframe existential issues. We propose that the structure of fairy tales allows the meaning of the story to be applied personally and that they also stimulate unconscious search. We examine the way in which hypnosis is achieved when fairy tales are read to children, as well as possible therapeutic uses of this learning set in therapy with both children and adults. We conclude by suggesting that fairy tales need to be given serious consideration as an alternative therapeutic trance procedure.

This demand requires the introduction of changes seeking the acquisition of competences in doctors' training.

  15. [Reactance proneness, collectivism, uniqueness, and resistance to persuasion]. (United States)

    Imajo, Shuzo


    This study examined the reliability and validity of Japanese psychological reactance scales. A total of 167 undergraduates completed a questionnaire of Therapeutic Reactance Scale (TRS), the Hong Reactance Scale (HRS), the Uniqueness Scale, and the Collectivism Scale. They also received messages involving three persuasion situations that were either high or low in terms of threat, and were asked to describe their reactions to them. The author categorized the reactions into three: acceptance, indirect resistance, and direct resistance. Reliabilities of the reactance scales were satisfactory. Their scores positively correlated with uniqueness scores, and negatively with collectivism scores. Those high on reactance proneness were less persuaded in two of the three situations. But in the third, an HRS by threat interaction was observed, indicating that only those who were high on reactance proneness under the high-threat condition showed resistance to persuasion. These results suggest that the Japanese versions of reactance scale were reliable and valid. However, the assertiveness aspect of TRS may not be appropriate for the definition of reactance. The influence of culture on psychological reactance was also discussed.

  16. The relations of family members' unique and shared perspectives of family dysfunction to dyad adjustment. (United States)

    Jager, Justin; Yuen, Cynthia X; Bornstein, Marc H; Putnick, Diane L; Hendricks, Charlene


    Among a community sample of families (N = 128), this study examined how family members' shared and unique perspectives of family dysfunction relate to dyad members' shared views of dyad adjustment within adolescent-mother, adolescent-father, and mother-father dyads. Independent of a family's family perspective (shared perspective of family dysfunction), the adolescent's unique perspective was associated with lower security and higher conflict with both mother and father; the father's unique perspective was associated with lower security and higher conflict with the adolescent, as well as lower marital quality with mother; and the mother unique perspective was associated with lower marital quality with the father. Moreover, for adolescent-parent dyads, compared with the parent unique perspective, the adolescent unique perspective was more strongly associated with dyad adjustment. These findings indicate that both shared and unique views of the family system-the adolescent's unique view in particular-independently relate to the health of family subsystems. They also suggest that research, as well as therapeutic interventions, that focus on just the shared view of the family may miss important elements of family dysfunction.

  18. Uniqueness vs non-uniqueness in complete connections with modified majority rules


    Dias, J. C. A.; Friedli, S.


    We take a closer look at a class of chains with complete connections introduced by Berger, Hoffman and Sidoravicius. Besides giving a sharper description of the uniqueness and non-uniqueness regimes, we show that if the pure majority rule used to fix the dependence on the past is replaced with a function that is Lipschitz at the origin, then uniqueness always holds, even with arbitrarily slow decaying variation.

  19. DRUMS: a human disease related unique gene mutation search engine. (United States)

    Li, Zuofeng; Liu, Xingnan; Wen, Jingran; Xu, Ye; Zhao, Xin; Li, Xuan; Liu, Lei; Zhang, Xiaoyan


    With the completion of the human genome project and the development of new methods for gene variant detection, the integration of mutation data and its phenotypic consequences has become more important than ever. Among all available resources, locus-specific databases (LSDBs) curate one or more specific genes' mutation data along with high-quality phenotypes. Although some genotype-phenotype data from LSDB have been integrated into central databases little effort has been made to integrate all these data by a search engine approach. In this work, we have developed disease related unique gene mutation search engine (DRUMS), a search engine for human disease related unique gene mutation as a convenient tool for biologists or physicians to retrieve gene variant and related phenotype information. Gene variant and phenotype information were stored in a gene-centred relational database. Moreover, the relationships between mutations and diseases were indexed by the uniform resource identifier from LSDB, or another central database. By querying DRUMS, users can access the most popular mutation databases under one interface. DRUMS could be treated as a domain specific search engine. By using web crawling, indexing, and searching technologies, it provides a competitively efficient interface for searching and retrieving mutation data and their relationships to diseases. The present system is freely accessible at

  20. Mitochondria targeting nano agents in cancer therapeutics (United States)

    Zhang, Xiao-Ying; Zhang, Pei-Ying


    Mitochondria have emerged as noteworthy therapeutic targets as their physiological functions are often altered in pathological conditions such as cancer. The electronic databases of MEDLINE, EMBASE and PubMed were searched for recent studies reporting the importance of mitochondria targeting nanoagents in cancer therapeutics. The concluding remarks of the above papers mostly confirmed the growing potential of these novel nanoagents in the area of anticancer research. Furthermore, numerous studies demonstrated the immense potential of nanocarriers in delivering mitochondria-acting compounds to their target site. Among the assemblage of nanomaterials, carbon nanotubes (CNTs) are becoming more prominent for drug delivery due to favorable attributes including their unique shape, which promotes cellular uptake, and large aspect ratio that facilitates conjugation of bioactive molecules on their surface. The present review focused on the current view of variable options available in mitochondria-targeting anticancer therapeutics. It may be concluded that improvements are essential for its establishment as a gold standard therapeutic option especially in the clinical setting. PMID:28105197

  11. Unraveling the evolution of uniquely human cognition. (United States)

    MacLean, Evan L


    A satisfactory account of human cognitive evolution will explain not only the psychological mechanisms that make our species unique, but also how, when, and why these traits evolved. To date, researchers have made substantial progress toward defining uniquely human aspects of cognition, but considerably less effort has been devoted to questions about the evolutionary processes through which these traits have arisen. In this article, I aim to link these complementary aims by synthesizing recent advances in our understanding of what makes human cognition unique, with theory and data regarding the processes of cognitive evolution. I review evidence that uniquely human cognition depends on synergism between both representational and motivational factors and is unlikely to be accounted for by changes to any singular cognitive system. I argue that, whereas no nonhuman animal possesses the full constellation of traits that define the human mind, homologies and analogies of critical aspects of human psychology can be found in diverse nonhuman taxa. I suggest that phylogenetic approaches to the study of animal cognition-which can address questions about the selective pressures and proximate mechanisms driving cognitive change-have the potential to yield important insights regarding the processes through which the human cognitive phenotype evolved.

    In this paper, we consider the zero distributions of -shift difference polynomials of meromorphic functions with zero order, and obtain two theorems that extend the classical Hayman results on the zeros of differential polynomials to -shift difference polynomials. We also investigate the uniqueness problem of -shift difference polynomials that share a common value.

  13. Novel therapeutic approaches for Leber's hereditary optic neuropathy. (United States)

    Iyer, Shilpa


    Many human childhood mitochondrial disorders result from abnormal mitochondrial DNA (mtDNA) and altered bioenergetics. These abnormalities span most of the mtDNA, demonstrating that there are no "unique" positions on the mitochondrial genome that when deleted or mutated produce a disease phenotype. This diversity implies that the relationship between mitochondrial genotype and clinical phenotype is very complex. The origins of clinical phenotypes are thus unclear, fundamentally difficult-to-treat, and are usually clinically devastating. Current treatment is largely supportive and the disorders progress relentlessly causing significant morbidity and mortality. Vitamin supplements and pharmacological agents have been used in isolated cases and clinical trials, but the efficacy of these interventions is unclear. In spite of recent advances in the understanding of the pathogenesis of mitochondrial diseases, a cure remains elusive. An optimal cure would be gene therapy, which involves introducing the missing gene(s) into the mitochondria to complement the defect. Our recent research results indicate the feasibility of an innovative protein-transduction ("protofection") technology, consisting of a recombinant mitochondrial transcription factor A (TFAM) that avidly binds mtDNA and permits efficient targeting into mitochondria in situ and in vivo. Thus, the development of gene therapy for treating mitochondrial disease offers promise, because it may circumvent the clinical abnormalities and the current inability to treat individual disorders in affected individuals. This review aims to focus on current treatment options and future therapeutics in mitochondrial disease treatment with a special emphasis on Leber's hereditary optic neuropathy.

  14. Therapeutic misadventure with paracetamol in children

    Directory of Open Access Journals (Sweden)

    Shivbalan So


    Full Text Available Paracetamol (acetaminophen, though considered a safe, "over the counter" analgesic and antipyretic, can cause liver injury with overdose. Therapeutic misadventure is a unique problem where the existing nomogram used for acute poisoning is not applicable. In this context, early initiation of N-acetylcysteine even before a biochemical evidence of liver injury may be beneficial. A series of 6 children with this type of paracetamol overdose are presented here to increase the awareness and understanding of this problem since no such data is available from India.

  16. Therapeutic Fascism: re-educating communists in Nazi-occupied Serbia, 1942-44. (United States)

    Antic, Ana


    This article probes the relationship between psychoanalysis and right-wing authoritarianism, and analyses a unique psychotherapeutic institution established by Serbia's World War II collaborationist regime. The extraordinary Institute for compulsory re-education of high-school and university students affiliated with the Communist resistance movement emerged in the context of a brutal civil war and violent retaliations against Communist activists, but its openly psychoanalytic orientation was even more astonishing. In order to stem the rapid spread of Communism, the collaborationist state, led by its most extreme fascistic elements, officially embraced psychotherapy, the 'talking cure' and Freudianism, and conjured up its own theory of mental pathology and trauma - one that directly contradicted the Nazi concepts of society and the individual. In the course of the experiment, Serbia's collaborationists moved away from the hitherto prevailing organicist, biomedical model of mental illness, and critiqued traditional psychiatry's therapeutic pessimism.

    Institute of Scientific and Technical Information of China (English)

    孔艳艳; 管一晖; 郑平


    Alzheimer' s disease (AD) is characterized by early neuropathological pathways-extracellular fibrillar β-amyloid (Aβ) deposits in the brain, intracellular neurofibrillary tangles (NFTs), possibly leading to synaptic dysfunction, neurodegeneration and cognitive/functional decline. The clinical diagnosis of probable AD based on standard diagnostic criteria does not take into account the long preclinical and prodromal course of AD. Diagnosis was based on structured history, neurological examination and neuropsychological assessment, with emphasis on qualitative as well as quantitative aspects of performance. AD-related pathophysiological changes can occur many years and even decades before the appearance of clinical dementia syndrome. Biomarkers that are related to the pathophysiology of AD may thus be helpful in detecting the preclinical stages of disease, and improve early and differential diagnosis, provided that the biomarkers were specific enough to avoid interfering with normal processes and accuracy of preclinical diagnosis of AD was increasingly important for therapeutic and prognostic investigations.%神经细胞外β淀粉样蛋白(Aβ)沉积和神经细胞内神经纤维缠结(NFTs)是阿尔茨海默病(AD)早期特征性病理标志,并可能导致继发性神经元丢失和轴突退行性变.目前临床诊断主要集中在病史,神经系统检查、神经心理评估来进行定量和定性分析,不能对临床前期AD做出有效评价,AD患者脑中出现上述病理改变后数年甚至数十年后才会出现临床症状.因此,若能针对AD病理进展的病理标记物早期诊断和关键靶点进行干预,对AD的疗效及预后有极为重要的作用.

  20. Unique device identification system. Final rule. (United States)


    The Food and Drug Administration (FDA) is issuing a final rule to establish a system to adequately identify devices through distribution and use. This rule requires the label of medical devices to include a unique device identifier (UDI), except where the rule provides for an exception or alternative placement. The labeler must submit product information concerning devices to FDA's Global Unique Device Identification Database (GUDID), unless subject to an exception or alternative. The system established by this rule requires the label and device package of each medical device to include a UDI and requires that each UDI be provided in a plain-text version and in a form that uses automatic identification and data capture (AIDC) technology. The UDI will be required to be directly marked on the device itself if the device is intended to be used more than once and intended to be reprocessed before each use.

    There is unique and groundbreaking science to be done with a new generation of UV spectrographs that cover wavelengths in the "Lyman Ultraviolet" (LUV; 912 - 1216 Ang). There is no astrophysical basis for truncating spectroscopic wavelength coverage anywhere between the atmospheric cutoff (3100 Ang) and the Lyman limit (912 Ang); the usual reasons this happens are all technical. The unique science available in the LUV includes critical problems in astrophysics ranging from the habitability of exoplanets to the reionization of the IGM. Crucially, the local Universe (z <= 0.1) is entirely closed to many key physical diagnostics without access to the LUV. These compelling scientific problems require overcoming these technical barriers so that future UV spectrographs can extend coverage to the Lyman limit at 912 Ang.

    Full Text Available 【Abstract】Concomitant dislocation of the tar-sometatarsal and metatarsophalangeal joints of foot is an extremely rare injury. Such injuries presenting in a single or adjacent dual rays have been described in few cases previously. We describe such an injury in adjacent three metatarsals of a polytrauma patient. These injuries are likely to be missed in the initial assessment of a polytrauma patient. These patients are at risk of an overlooked diagnosis but the consequences of missing this type of injury may be Vivek Trikha*, Tarun Goyal, Amit K Agarwal quite severe. This case is presented in view of its unique-ness along with possible mechanism of injury, the sequence of reduction and follow-up. Knowledge of such injury and its proper management may be useful to the trauma surgeons. Key words: Metatarsal bones; Metatarsophalangeal joint; Wounds and injuries

    Full Text Available Classical studies on pre-modern Indian social structure have suggested apparent differences between the Indian caste system and social stratification as one can discern in other parts of the world. However, one needs to question such dogmatic assertions that such vast differences really existed. An endeavor is made in this research paper to reflect on the nature of caste hierarchy in pre-modern India. The caste system forms the significant basis of pre-modern Indian social structure. Early writers conceived the caste system of pre-modern India as something unique to India. An attempt is made to question this application of theory of uniqueness in the case of India.

    SUN Yao-qiang; MA Chao-wei


    The uniqueness problem of entire functions concerning weighted sharing was discussed, and the following theorem was proved. Let f and g be two non-constant entire functions, m, n and k three positive integers, and n>2k+4. If Em(1,(f n)(k))= Em(1,(gn)(k)), then either f (z)=c1ecz and g(z)= c2e-cz, or f =tg, where c, c1 and c2 are three constants satisfying (-1)k(c1c2)n(nc)2k=1, and t is a constant satisfying t n=1. The theorem generalizes the result of Fang [Fang ML, Uniqueness and value sharing of entire functions, Computer & Mathematics with Applications, 2002, 44: 823-831].

    An 18-year-old Asian girl was referred to the nephrology unit with rapidly progressive renal failure. At the age of 15 she was diagnosed as having systemic lupus erythematosus but had defaulted treatment. Her renal functions improved with cyclophosphamide pulse treatment but she continued to have central nervous system vasculitis, gastrointestinal vasculitis and opportunistic infections making her a unique and challenging case of systemic lupus erythematosus.

  9. Uniqueness from locality and BCFW shifts


    Rodina, Laurentiu


    We introduce a BCFW shift which can be used to recursively build the full Yang-Mills amplitude as a function of polarization vectors. Furthermore, in line with the recent results of arXiv:1612.02797, we conjecture that the Yang-Mills scattering amplitude is uniquely fixed by locality and demanding the usual asymptotic behavior under a sufficient number of shifts. Unitarity therefore emerges from locality and constructability. We prove this statement at the leading order in the soft expansion.

Results: After therapy for 6 - 18 months, the ZUNG scores of parents in intervention group were significantly lower than those in control group and before treatment (P<0. 05). There were no significant differences in ZUNG scores before and after treatment in control group. The proportion of proactive parents in intervention group was significantly higher than that

  12. Frankincense--therapeutic properties. (United States)

    Al-Yasiry, Ali Ridha Mustafa; Kiczorowska, Bożena


    Recently, increasing interest in natural dietary and therapeutic preparations used as dietary supplements has been observed. One of them is frankincense. This traditional medicine of the East is believed to have anti-inflammatory, expectorant, antiseptic, and even anxiolytic and anti-neurotic effects. The present study aims to verify the reported therapeutic properties of Boswellia resin and describe its chemical composition based on available scientific studies. The main component of frankincense is oil (60%). It contains mono- (13%) and diterpenes (40%) as well as ethyl acetate (21.4%), octyl acetate (13.4%) and methylanisole (7.6%). The highest biological activity among terpenes is characteristic of 11-keto-ß-acetyl-beta-boswellic acid, acetyl-11-keto-ß-boswellic acid and acetyl-α-boswellic acid. Contemporary studies have shown that resin indeed has an analgesic, tranquilising and anti-bacterial effects. From the point of view of therapeutic properties, extracts from Boswellia serrata and Boswellia carterii are reported to be particularly useful. They reduce inflammatory conditions in the course of rheumatism by inhibiting leukocyte elastase and degrading glycosaminoglycans. Boswellia preparations inhibit 5-lipoxygenase and prevent the release of leukotrienes, thus having an anti-inflammatory effect in ulcerative colitis, irritable bowel syndrome, bronchitis and sinusitis. Inhalation and consumption of Boswellia olibanum reduces the risk of asthma. In addition, boswellic acids have an antiproliferative effect on tumours. They inhibit proliferation of tumour cells of the leukaemia and glioblastoma subset. They have an anti-tumour effect since they inhibit topoisomerase I and II-alpha and stimulate programmed cell death (apoptosis).

  13. [Therapeutic patient education revisited]. (United States)

    Ruiz, Juan


    The therapeutic patient education is an absolute necessity in the management of chronic diseases including diabetes. This discipline promotes personal autonomy to live optimally, to achieve personal and professional projects, despite the constraints of the disease and treatments. The DAWN2 study demonstrates the systemic effects of this disease that goes beyond simple glycemic control. The biopsychosocial dimension needs to be better explored. Other assessment tools should be used to better manage these patients. Exploring the health literacy and numeracy are other tools that can explore the problems for socially disadvantaged patients. The main goal is development of patient capabilities and his environment for the development of the human person.

  14. [Achievement of therapeutic objectives]. (United States)

    Mantilla, Teresa


    Therapeutic objectives for patients with atherogenic dyslipidemia are achieved by improving patient compliance and adherence. Clinical practice guidelines address the importance of treatment compliance for achieving objectives. The combination of a fixed dose of pravastatin and fenofibrate increases the adherence by simplifying the drug regimen and reducing the number of daily doses. The good tolerance, the cost of the combination and the possibility of adjusting the administration to the patient's lifestyle helps achieve the objectives for these patients with high cardiovascular risk.

    Cellulite is a condition that affects the vast majority of women. Although it is of no danger to one's overall health, cellulite can be psychosocially debilitating. Consequently, much research has been devoted to understanding cellulite and its etiopathogenesis. With additional insights into the underlying causes of its clinical presentation, therapeutic modalities have been developed that offer hope to cellulite sufferers. This review examines evidence for topical treatments, noninvasive energy-based devices, and recently developed minimally invasive interventions that may finally provide a solution. ©2015 Frontline Medical Communications.

  16. Exploiting Unique Structural and Functional Properties of Malarial Glycolytic Enzymes for Antimalarial Drug Development

    Directory of Open Access Journals (Sweden)

    Asrar Alam


    Full Text Available Metabolic enzymes have been known to carry out a variety of functions besides their normal housekeeping roles known as “moonlighting functions.” These functionalities arise from structural changes induced by posttranslational modifications and/or binding of interacting proteins. Glycolysis is the sole source of energy generation for malaria parasite Plasmodium falciparum, hence a potential pathway for therapeutic intervention. Crystal structures of several P. falciparum glycolytic enzymes have been solved, revealing that they exhibit unique structural differences from the respective host enzymes, which could be exploited for their selective targeting. In addition, these enzymes carry out many parasite-specific functions, which could be of potential interest to control parasite development and transmission. This review focuses on the moonlighting functions of P. falciparum glycolytic enzymes and unique structural differences and functional features of the parasite enzymes, which could be exploited for therapeutic and transmission blocking interventions against malaria.

  18. Stigma: a Unique Source of Distress for Family Members of Individuals with Mental Illness. (United States)

    Muralidharan, Anjana; Lucksted, Alicia; Medoff, Deborah; Fang, Li Juan; Dixon, Lisa


    To distinguish the impact of mental illness stigma from that of other negative caregiving experiences, this study examined the unique relationships between stigma and caregiver/family functioning. Adult relatives (n = 437) of individuals with mental illness completed questionnaires regarding caregiving experiences, distress, empowerment, and family functioning, as part of a larger study. Regression analyses examined the relationship between stigma and caregiver/family variables, while controlling for other negative caregiving experiences. Stigma was uniquely associated with caregiver distress, empowerment, and family functioning. Mental illness stigma is a potent source of distress for families and an important target of family services.

    Full Text Available INTRODUÇÃO: O estabelecimento de uma aliança terapêutica de boa qualidade em uma psicoterapia psicanalítica é fundamental para o processo terapêutico. Este estudo avaliou a influência do nível de funcionamento defensivo do paciente na qualidade da aliança terapêutica estabelecida durante a psicoterapia. MÉTODO: Para avaliação da qualidade da aliança estabelecida, pacientes em psicoterapia psicanalítica e seus respectivos terapeutas responderam ao Helping Alliance Questionnaire (versão paciente e versão terapeuta, respectivamente. O nível defensivo foi inferido através da Escala de Funcionamento Defensivo proposta no Manual de Diagnóstico e Estatística das Perturbações Mentais, quarta edição, texto revisado. RESULTADOS: Não houve associação entre o estabelecimento de uma aliança terapêutica de boa qualidade e o nível defensivo do paciente. No entanto, houve diferença significativa quando a versão do terapeuta foi comparada com a respondida pelo paciente: os pacientes estabeleceram uma aliança terapêutica de melhor qualidade em relação a seus terapeutas do que o inverso. CONCLUSÕES: O fato de a aliança terapêutica de boa qualidade ter se estabelecido independentemente do nível defensivo do paciente sugere que o treinamento e as características pessoais do terapeuta podem levar a uma capacidade de conectar-se com o paciente, apesar do grau de comprometimento do seu funcionamento psíquico.BACKGROUND: The quality of a therapeutic alliance is essential in psychoanalytic psychotherapy and influences the therapeutic process. This study evaluated the relationship between the level of defense mechanisms and the quality of therapeutic alliance established during psychotherapy.

    Full Text Available The spectrum of known black-hole solutions to the stationary Einstein equations has been steadily increasing, sometimes in unexpected ways. In particular, it has turned out that not all black-hole-equilibrium configurations are characterized by their mass, angular momentum and global charges. Moreover, the high degree of symmetry displayed by vacuum and electro vacuum black-hole spacetimes ceases to exist in self-gravitating non-linear field theories. This text aims to review some developments in the subject and to discuss them in light of the uniqueness theorem for the Einstein-Maxwell system.

  3. Unique double recurrence of cerebral arteriovenous malformation. (United States)

    Nagm, Alhusain; Horiuchi, Tetsuyoshi; Ichinose, Shunsuke; Hongo, Kazuhiro


    Surgically treated patients with arteriovenous malformations (AVMs) are considered cured when the postoperative angiogram proves complete resection. However, despite no residual nidus or early draining vein on postoperative angiogram, rare instances of AVM recurrence have been reported in adults. In this paper, the authors present a case of a 24-year-old woman with asymptomatic double recurrence of her cerebral AVM after angiographically proven complete resection. To the authors' knowledge, this patient represents the first case with double de novo asymptomatic recurrence of Spetzler-Martin grade I AVM. Also, she represents the first case with unique AVM criteria in each recurrence.

    Full Text Available We present a unique variation in the arterial pattern of superficial palmar arch in which it was completed by one of the large terminal branches of radial artery. The origin of the arteria radialis indicis was also peculiar that it was arising from the communicating branch of the radial artery and further reinforced by the first dorsal metacarpal artery that joined it after reaching the volar aspect. Pertinent anatomical knowledge regarding the variations of the palmar arch is significant for the purposes of microvascular repairs and re-implantations.

  5. Type III factors with unique Cartan decomposition

    Houdayer, Cyril


    We prove that for any free ergodic nonsingular nonamenable action \\Gamma\\ \\actson (X,\\mu) of all \\Gamma\\ in a large class of groups including all hyperbolic groups, the associated group measure space factor $L^\\infty(X) \\rtimes \\Gamma$ has L^\\infty(X) as its unique Cartan subalgebra, up to unitary conjugacy. This generalizes the probability measure preserving case that was established in [PV12]. We also prove primeness and indecomposability results for such crossed products, for the corresponding orbit equivalence relations and for arbitrary amalgamated free products $M_1 *_B M_2$ over a subalgebra B of type I.

    Analysis to discriminate Centauro events from normal events is made without previous identification of secondary emitted particles. For this purpose their energy and derived quantities like distance from the center of momenta it were mainly used. As a result we found in a sample of (280+87) experimental events only 3 were compatible with 5 Centauro events, but none of them dad a high content of hadrons, characteristic of Centauro events. With this result we are confident about the uniqueness of Centauro events, especially for two events that have vertex directly determined. Comparing with some interaction models features we depict a possible scenario to explain Centauro events.

    Chrúsciel, P T; MacCallum, M A H; Chru\\'sciel, Piotr T.; Jezierski, Jacek; Callum, Malcolm A.H. Mac


    It is shown that the only functionals, within a natural class, which are monotonic in time for all solutions of the vacuum Einstein equations admitting a smooth ``piece'' of conformal null infinity Scri, are those depending on the metric only through a specific combination of the Bondi `mass aspect' and other next--to--leading order terms in the metric. Under the extra condition of passive BMS invariance, the unique such functional (up to a multiplicative factor) is the Trautman--Bondi energy. It is also shown that this energy remains well-defined for a wide class of `polyhomogeneous' metrics.

    Consider a market where producers submit supply functions to a procurement auction with uncertain demand, e.g. an electricity auction. In the Supply Function Equilibrium (SFE), every firm commits to the supply function that maximises expected profit in the one-shot game given the supply functions of competitors. A basic weakness of the SFE is the presence of multiple equilibria. This paper shows that with (i) symmetric producers, (ii) perfectly inelastic demand, (iii) a price cap, and (iv) capacity constraints that bind with a positive probability, there exists a unique, symmetric SFE.

  11. Therapeutic Vaccine Strategies against Human Papillomavirus

    Directory of Open Access Journals (Sweden)

    Hadeel Khallouf


    Full Text Available High-risk types of human papillomavirus (HPV cause over 500,000 cervical, anogenital and oropharyngeal cancer cases per year. The transforming potential of HPVs is mediated by viral oncoproteins. These are essential for the induction and maintenance of the malignant phenotype. Thus, HPV-mediated malignancies pose the unique opportunity in cancer vaccination to target immunologically foreign epitopes. Therapeutic HPV vaccination is therefore an ideal scenario for proof-of-concept studies of cancer immunotherapy. This is reflected by the fact that a multitude of approaches has been utilized in therapeutic HPV vaccination design: protein and peptide vaccination, DNA vaccination, nanoparticle- and cell-based vaccines, and live viral and bacterial vectors. This review provides a comprehensive overview of completed and ongoing clinical trials in therapeutic HPV vaccination (summarized in tables, and also highlights selected promising preclinical studies. Special emphasis is given to adjuvant science and the potential impact of novel developments in vaccinology research, such as combination therapies to overcome tumor immune suppression, the use of novel materials and mouse models, as well as systems vaccinology and immunogenetics approaches.

  12. Brain metastasis: new opportunities to tackle therapeutic resistance. (United States)

    Seoane, Joan; De Mattos-Arruda, Leticia


    Brain metastasis is a devastating complication of cancer with unmet therapeutic needs. The incidence of brain metastasis has been rising in cancer patients and its response to treatment is limited due to the singular characteristics of brain metastasis (i.e., blood-brain-barrier, immune system, stroma). Despite improvements in the treatment and control of extracranial disease, the outcomes of patients with brain metastasis remain dismal. The mechanisms that allow tumor cells to promulgate metastases to the brain remain poorly understood. Further work is required to identify the molecular alterations inherent to brain metastasis in order to identify novel therapeutic targets and explicate the mechanisms of resistance to systemic therapeutics. In this article, we review current knowledge of the unique characteristics of brain metastasis, implications in therapeutic resistance, and the possibility of developing biomarkers to rationally guide the use of targeted agents.

  13. Astronomy Outreach for Large and Unique Audiences (United States)

    Lubowich, D.; Sparks, R. T.; Pompea, S. M.; Kendall, J. S.; Dugan, C.


    In this session, we discuss different approaches to reaching large audiences. In addition to star parties and astronomy events, the audiences for some of the events include music concerts or festivals, sick children and their families, minority communities, American Indian reservations, and tourist sites such as the National Mall. The goal is to bring science directly to the public—to people who attend astronomy events and to people who do not come to star parties, science museums, or science festivals. These programs allow the entire community to participate in astronomy activities to enhance the public appreciation of science. These programs attract large enthusiastic crowds often with young children participating in these family learning experiences. The public will become more informed, educated, and inspired about astronomy and will also be provided with information that will allow them to continue to learn after this outreach activity. Large and unique audiences often have common problems, and their solutions and the lessons learned will be presented. Interaction with the participants in this session will provide important community feedback used to improve astronomy outreach for large and unique audiences. New ways to expand astronomy outreach to new large audiences will be discussed.

  14. An experiment on Lowest Unique Integer Games (United States)

    Yamada, Takashi; Hanaki, Nobuyuki


    We experimentally study Lowest Unique Integer Games (LUIGs) to determine if and how subjects self-organize into different behavioral classes. In a LUIG, N(≥ 3) players submit a positive integer up to M and the player choosing the smallest number not chosen by anyone else wins. LUIGs are simplified versions of real systems such as Lowest/Highest Unique Bid Auctions that have been attracting attention from scholars, yet experimental studies are scarce. Furthermore, LUIGs offer insights into choice patterns that can shed light on the alleviation of congestion problems. Here, we consider four LUIGs with N = { 3 , 4 } and M = { 3 , 4 } . We find that (a) choices made by more than 1/3 of subjects were not significantly different from what a symmetric mixed-strategy Nash equilibrium (MSE) predicts; however, (b) subjects who behaved significantly differently from what the MSE predicts won the game more frequently. What distinguishes subjects was their tendencies to change their choices following losses.

    Full Text Available Paola Cappello, Moitza Principe, Francesco Novelli Department of Molecular Biotechnologies and Health Sciences, Center for Experimental Research and Medical Studies, AOU Città della Salute e della Scienza di Torino, University of Turin, Turin, Italy Abstract: Pancreatic ductal adenocarcinoma (PDA is a lethal disease and is one of the cancers that is most resistant to traditional therapies. Historically, neither chemotherapy nor radiotherapy has provided any significant increase in the survival of patients with PDA. Despite intensive efforts, any attempts to improve the survival in the past 15 years have failed. This holds true even after the introduction of molecularly targeted agents, chosen on the basis of their involvement in pathways that are considered to be important in PDA development and progression. Recently, however, FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin treatment has provided a limited survival advantage in patients with advanced PDA. Therefore, effective therapeutic strategies are urgently needed to improve the survival rate of patients with PDA. Results from the last 10 years of research in the field of PDA have helped to identify new immunological targets and develop new vaccines that are capable of stimulating an immune response. In addition, the information obtained about the role of the tumor microenvironment in suppressing the immune response and the possibility of targeting PDA microenvironment to limit immune suppression and enhance the response of effector T-cells has opened new avenues for treating this incurable disease. The time is ripe for developing new therapeutic approaches that are able to effectively counteract the progression and spreading of PDA. This review discusses the potential prospects in the care of patients with pancreatic cancer through vaccination and its combination therapy with surgery, chemotherapy, targeting of the tumor microenvironment, and inhibition of immunological

  19. Functio Laesa: Cancer Inflammation and Therapeutic Resistance. (United States)

    Liu, Mingen; Kalbasi, Anusha; Beatty, Gregory L


    Tumor, calor, rubor, and dolor describe four cardinal signs of inflammation. The fifth-functio laesa, or loss of function-was promulgated by Rudolf Virchow, who, in the 19th century, also noted an intricate link between inflammation and cancer. However, the role of cancer inflammation in driving loss of therapeutic efficacy has only recently been fully appreciated, as a result of molecular and immunohistochemical approaches applied in clinical medicine and the availability of novel agents for modulating inflammation. This review focuses on clinical evidence from solid malignancies that have shaped our view of how the immune system regulates cancer development, progression, and response to treatment. Understanding the multifaceted relationship between inflammation and patient outcomes has the potential to advance prognostic tools and uncover therapeutic opportunities for improving clinical outcomes.


    Petryszyn, Paweł; Wiela-Hojeńska, Anna


    The fact that resources for health care are limited has been found as a rationale for the development of pharmacoeconomics. Pharmacoeconomic analysis identifies, measures and compares the costs and the economic, clinical and humanistic outcomes of diseases, drug therapies and programmes directed to these diseases. As health care expenditures have escalated over the past decades, the number of its applications has increased. Taking into consideration outcome and economic issues and establishing their mutual relationship helps proper resource allocation. In the case of some effective and toxic drugs therapeutic drug monitoring has been proven to allow obtaining the desired clinical effects safely and thus to improve outcome. However, it requires the presence of clinical pharmacology or clinical pharmacy service within a hospital, which in turn is associated with some additional costs. This review sums up the results of pharmacoeconomic studies relevant to the use of therapeutic drug monitoring in case of the medicines for which it has been commonly performed so far.

    朱冬云; 毕礼明; 陈英兰


    “善治者治皮毛”是医家治疗疾病的最重要原则之一.慢性肾脏病(CKD)极为常见,其治疗目的包括延缓进展、需要评估心血管危险因素、鉴别和治疗相关的并发症,或者行肾脏替代治疗.综合的多重干预可延缓甚至阻断CKD进展,减少CKD死亡的首位原因心血管并发症的发生.本文试着讨论“善治者治皮毛”与CKD防治策略的关系.%The proverb of good doctor to cure fur was from "Internal Classic of Huang Di". It had been widely guided by the medical scientist as one of the most important therapeutic principles. And CKD ( chronic kidney disease )was very common. The objectives were to slow the progression of CKD to take all the cardiovascular risk factors into account,to screen for and treat specific complications and to prepare,if necessary,for renal replacement treatment. Comprehensive multidisciplinary management could slow or even stop the progression of CKD and reduce its cardiovascular complications,which was the leading cause of death in these patients. In this paper,we tried to discuss on the relationship between the proverb of good doctor to cure fur and the preventive or therapeutic strategies of chronic kidney disease.

  2. The core and unique proteins of haloarchaea

    Directory of Open Access Journals (Sweden)

    Capes Melinda D


    Full Text Available Abstract Background Since the first genome of a halophilic archaeon was sequenced in 2000, biologists have been advancing the understanding of genomic characteristics that allow for survival in the harsh natural environments of these organisms. An increase in protein acidity and GC-bias in the genome have been implicated as factors in tolerance to extreme salinity, desiccation, and high solar radiation. However, few previous attempts have been made to identify novel genes that would permit survival in such extreme conditions. Results With the recent release of several new complete haloarchaeal genome sequences, we have conducted a comprehensive comparative genomic analysis focusing on the identification of unique haloarchaeal conserved proteins that likely play key roles in environmental adaptation. Using bioinformatic methods, we have clustered 31,312 predicted proteins from nine haloarchaeal genomes into 4,455 haloarchaeal orthologous groups (HOGs. We assigned likely functions by association with established COG and KOG databases in NCBI. After identifying homologs in four additional haloarchaeal genomes, we determined that there were 784 core haloarchaeal protein clusters (cHOGs, of which 83 clusters were found primarily in haloarchaea. Further analysis found that 55 clusters were truly unique (tucHOGs to haloarchaea and qualify as signature proteins while 28 were nearly unique (nucHOGs, the vast majority of which were coded for on the haloarchaeal chromosomes. Of the signature proteins, only one example with any predicted function, Ral, involved in desiccation/radiation tolerance in Halobacterium sp. NRC-1, was identified. Among the core clusters, 33% was predicted to function in metabolism, 25% in information transfer and storage, 10% in cell processes and signaling, and 22% belong to poorly characterized or general function groups. Conclusion Our studies have established conserved groups of nearly 800 protein clusters present in all

  3. Unique metabolic features of stem cells, cardiomyocytes, and their progenitors. (United States)

    Gaspar, John Antonydas; Doss, Michael Xavier; Hengstler, Jan Georg; Cadenas, Cristina; Hescheler, Jürgen; Sachinidis, Agapios


    Recently, growing attention has been directed toward stem cell metabolism, with the key observation that the plasticity of stem cells also reflects the plasticity of their energy substrate metabolism. There seems to be a clear link between the self-renewal state of stem cells, in which cells proliferate without differentiation, and the activity of specific metabolic pathways. Differentiation is accompanied by a shift from anaerobic glycolysis to mitochondrial respiration. This metabolic switch of differentiating stem cells is required to cover the energy demands of the different organ-specific cell types. Among other metabolic signatures, amino acid and carbohydrate metabolism is most prominent in undifferentiated embryonic stem cells, whereas the fatty acid metabolic signature is unique in cardiomyocytes derived from embryonic stem cells. Identifying the specific metabolic pathways involved in pluripotency and differentiation is critical for further progress in the field of developmental biology and regenerative medicine. The recently generated knowledge on metabolic key processes may help to generate mature stem cell-derived somatic cells for therapeutic applications without the requirement of genetic manipulation. In the present review, the literature about metabolic features of stem cells and their cardiovascular cell derivatives as well as the specific metabolic gene signatures differentiating between stem and differentiated cells are summarized and discussed.

  4. Conditional and Unique Coloring of Graphs

    CERN Document Server

    Reddy, P Venkata Subba


    For integers $k, r > 0$, a conditional $(k,r)$-coloring of a graph $G$ is a proper $k$-coloring of the vertices of $G$ such that every vertex $v$ of degree $d(v)$ in $G$ is adjacent to at least $\\min\\{r, d(v)\\}$ differently colored vertices. Given $r$, the smallest integer $k$ for which $G$ has a conditional $(k,r)$-coloring is called the $r$th order conditional chromatic number $\\chi_r(G)$ of $G$. We give results (exact values or bounds for $\\chi_r(G)$, depending on $r$) related to the conditional coloring of some graphs. We introduce \\emph{unique conditional colorability} and give some related results. (Keywords. cartesian product of graphs; conditional chromatic number; gear graph; join of graphs.)

  5. Developing innovative programs for unique student populations. (United States)

    Heath, D A; Caruso, J; Chauncey, D M


    Optometric education has been faced with ever-increasing expectations. These include the ability to educate students and practitioners to care for new patient populations, deal with more diverse and complex clinical problems, to be significant participants in the research community and to fulfill leadership positions within the profession. To fulfill this expectation, schools and colleges need to diversify their program offerings to attract and educate unique student populations who come from diverse backgrounds and bring a range of pre-existing knowledge and skills. This paper provides an overview of The New England College of Optometry's efforts in this area and two programs, the "Advanced Standing International Program" and the "Accelerated Doctor of Optometry Degree Program," are examined in detail. An emphasis is placed on outcomes assessment to ensure the programs are fulfilling their purpose and the results of a retrospective analysis of the two programs is provided.

  6. Computational Transition at the Uniqueness Threshold

    CERN Document Server

    Sly, Allan


    The hardcore model is a model of lattice gas systems which has received much attention in statistical physics, probability theory and theoretical computer science. It is the probability distribution over independent sets $I$ of a graph weighted proportionally to $\\lambda^{|I|}$ with fugacity parameter $\\lambda$. We prove that at the uniqueness threshold of the hardcore model on the $d$-regular tree, approximating the partition function becomes computationally hard on graphs of maximum degree $d$. Specifically, we show that unless NP$=$RP there is no polynomial time approximation scheme for the partition function (the sum of such weighted independent sets) on graphs of maximum degree $d$ for fugacity $\\lambda_c(d) 0$. Weitz produced an FPTAS for approximating the partition function when $0<\\lambda < \\lambda_c(d)$ so this result demonstrates that the computational threshold exactly coincides with the statistical physics phase transition thus confirming the main conjecture of [28]. We further analyze the s...

  7. Organizing the spatially and temporally unique hydrosphere (United States)

    Berghuijs, Wouter


    Growing anthropogenic activity is quickly changing the hydrosphere. Panta Rhei calls for improved understanding of changing hydrosphere dynamics in their connection with human systems. I argue that progress within the Panta Rhei initiative is strongly limited by the absence of hydrological principles that help to organise our spatially and temporally unique hydrosphere; without guiding principles (e.g. classification systems) hydrology will continue to be a case study dominated science that will have a hard time to efficiently improve understanding, estimation and prediction of human affected systems. Exposing such organising principles should not be considered as a step backwards into the recent PUB decade. Instead, it should be regarded as an exciting scientific challenge that is becoming increasingly relevant now the hydrosphere is quickly changing.

    Gürdeniz, Gözde; Jensen, Morten Georg; Meier, Sebastian


    Evaluation of health related effects of beer intake is hampered by the lack of accurate tools for assessing intakes (biomarkers). Therefore, we identified plasma and urine metabolites associated with recent beer intake by untargeted metabolomics and established a characteristic metabolite pattern...... representing raw materials and beer production as a qualitative biomarker of beer intake. In a randomized, crossover, single-blinded meal study (MSt1) 18 participants were given one at a time four different test beverages: strong, regular and non-alcoholic beers and a soft drink. Four participants were...... assigned to have two additional beers (MSt2). In addition to plasma and urine samples, test beverages, wort and hops extract were analyzed by UPLC-QTOF. A unique metabolite pattern reflecting beer metabolome, including metabolites derived from beer raw material (i.e. N-methyl tyramine sulfate and the sum...

  11. The bacterial magnetosome: a unique prokaryotic organelle. (United States)

    Lower, Brian H; Bazylinski, Dennis A


    The bacterial magnetosome is a unique prokaryotic organelle comprising magnetic mineral crystals surrounded by a phospholipid bilayer. These inclusions are biomineralized by the magnetotactic bacteria which are ubiquitous, aquatic, motile microorganisms. Magnetosomes cause cells of magnetotactic bacteria to passively align and swim along the Earth's magnetic field lines, as miniature motile compass needles. These specialized compartments consist of a phospholipid bilayer membrane surrounding magnetic crystals of magnetite (Fe3O4) or greigite (Fe3S4). The morphology of these membrane-bound crystals varies by species with a nominal magnetic domain size between 35 and 120 nm. Almost all magnetotactic bacteria arrange their magnetosomes in a chain within the cell there by maximizing the magnetic dipole moment of the cell. It is presumed that magnetotactic bacteria use magnetotaxis in conjunction with chemotaxis to locate and maintain an optimum position for growth and survival based on chemistry, redox and physiology in aquatic habitats with vertical chemical concentration and redox gradients. The biosynthesis of magnetosomes is a complex process that involves several distinct steps including cytoplasmic membrane modifications, iron uptake and transport, initiation of crystallization, crystal maturation and magnetosome chain formation. While many mechanistic details remain unresolved, magnetotactic bacteria appear to contain the genetic determinants for magnetosome biomineralization within their genomes in clusters of genes that make up what is referred to as the magnetosome gene island in some species. In addition, magnetosomes contain a unique set of proteins, not present in other cellular fractions, which control the biomineralization process. Through the development of genetic systems, proteomic and genomic work, and the use of molecular and biochemical tools, the functions of a number of magnetosome membrane proteins have been demonstrated and the molecular

  12. Implementation of nanoparticles in therapeutic radiation oncology (United States)

    Beeler, Erik; Gabani, Prashant; Singh, Om V.


    Development and progress of cancer is a very complex disease process to comprehend because of the multiple changes in cellular physiology, pathology, and pathophysiology resulting from the numerous genetic changes from which cancer originates. As a result, most common treatments are not directed at the molecular level but rather at the tissue level. While personalized care is becoming an increasingly aim, the most common cancer treatments are restricted to chemotherapy, radiation, and surgery, each of which has a high likelihood of resulting in rather severe adverse side effects. For example, currently used radiation therapy does not discriminate between normal and cancerous cells and greatly relies on the external targeting of the radiation beams to specific cells and organs. Because of this, there is an immediate need for the development of new and innovative technologies that help to differentiate tumor cells and micrometastases from normal cells and facilitate the complete destruction of those cells. Recent advancements in nanoscience and nanotechnology have paved a way for the development of nanoparticles (NPs) as multifunctional carriers to deliver therapeutic radioisotopes for tumor targeted radiation therapy, to monitor their delivery, and improve the therapeutic index of radiation and tumor response to the treatment. The application of NPs in radiation therapy has aimed to improve outcomes in radiation therapy by increasing therapeutic effect in tumors and reducing toxicity on normal tissues. Because NPs possess unique properties, such as preferential accumulation in tumors and minimal uptake in normal tissues, it makes them ideal for the delivery of radiotherapy. This review provides an overview of the recent development of NPs for carrying and delivering therapeutic radioisotopes for systemic radiation treatment for a variety of cancers in radiation oncology.

  15. [Nuclear transfer and therapeutic cloning]. (United States)

    Xu, Xiao-Ming; Lei, An-Min; Hua, Jin-Lian; Dou, Zhong-Ying


    Nuclear transfer and therapeutic cloning have widespread and attractive prospects in animal agriculture and biomedical applications. We reviewed that the quality of oocytes and nuclear reprogramming of somatic donor cells were the main reasons of the common abnormalities in cloned animals and the low efficiency of cloning and showed the problems and outlets in therapeutic cloning, such as some basic problems in nuclear transfer affected clinical applications of therapeutic cloning. Study on isolation and culture of nuclear transfer embryonic stem (ntES) cells and specific differentiation of ntES cells into important functional cells should be emphasized and could enhance the efficiency. Adult stem cells could help to cure some great diseases, but could not replace therapeutic cloning. Ethics also impeded the development of therapeutic cloning. It is necessary to improve many techniques and reinforce the research of some basic theories, then somatic nuclear transfer and therapeutic cloning may apply to agriculture reproduction and benefit to human life better.

  16. Structural contributions of antipsychotic drugs to their therapeutic profiles and metabolic side effects. (United States)

    Jafari, Somayeh; Fernandez-Enright, Francesca; Huang, Xu-Feng


    Antipsychotic drugs have various neuropharmacological properties as a result of their structural diversity. Despite their therapeutic benefits, most of the prescribed atypical antipsychotics can induce severe side effects, including weight gain, type II diabetes mellitus, and cardiovascular diseases. Among the developed atypical antipsychotic agents, tetracyclic dibenzodiazepine and thienobenzodiazepine compounds, particularly clozapine and olanzapine, are associated with the greatest weight gain and metabolic disturbances. However, the unique chemical structure of these compounds causes the low risk of side effects reported for typical antipsychotics (e.g. extrapyramidal symptoms and tardive dyskinesia). This report reviews the recent discovery of the potential role of the chemical structure of antipsychotics in their therapeutic properties and metabolic disturbances. By developing structure-activity relationship studies for atypical antipsychotics, we will improve our understanding of the structural modifications of these chemical classes that lead to reduced weight gain, which will be an invaluable step toward the discovery of the next generation of atypical antipsychotics. In this review, we suggest that a novel dibenzodiazepine or thienobenzodiazepine antipsychotic drug with lower affinity for H(1) receptors may significantly advance schizophrenia therapy.

    Mentoring plays a significant role in business, industry, government, education, and healthcare. Mentoring relationships help promote the individual's professional growth and development. Such development involves knowledge and skill acquisition, which is facilitated by interaction with other, more experienced and proficient professionals. The Belcher-Sibbald Continuum of Learning describes the relationship among the concepts of role modeling, networking, preceptoring, and mentoring. Each concept is defined and described as a unique relationship which promotes professional growth and development. In addition, three mentoring/networking relationships in the context of the wound care community are presented to provide insight into this type of relationship.

  19. Designing phage therapeutics. (United States)

    Goodridge, Lawrence D


    Phage therapy is the application of phages to bodies, substances, or environments to effect the biocontrol of pathogenic or nuisance bacteria. To be effective, phages, minimally, must be capable of attaching to bacteria (adsorption), killing those bacteria (usually associated with phage infection), and otherwise surviving (resisting decay) until they achieve attachment and subsequent killing. While a strength of phage therapy is that phages that possess appropriate properties can be chosen from a large diversity of naturally occurring phages, a more rational approach to phage therapy also can include post-isolation manipulation of phages genetically, phenotypically, or in terms of combining different products into a single formulation. Genetic manipulation, especially in these modern times, can involve genetic engineering, though a more traditional approach involves the selection of spontaneously occurring phage mutants during serial transfer protocols. While genetic modification typically is done to give rise to phenotypic changes in phages, phage phenotype alone can also be modified in vitro, prior to phage application for therapeutic purposes, as for the sake of improving phage lethality (such as by linking phage virions to antibacterial chemicals such as chloramphenicol) or survival capabilities (e.g., via virion PEGylation). Finally, phages, both naturally occurring isolates or otherwise modified constructs, can be combined into cocktails which provide collectively enhanced capabilities such as expanded overall host range. Generally these strategies represent different routes towards improving phage therapy formulations and thereby efficacy through informed design.

    Omura, S; Sano, H; Sunazuka, T


    Sixty-six derivatives of spiramycin I and neospiramycin I were synthesized and evaluated by four parameters, MIC, affinity to ribosomes (ID50), therapeutic effect in mice and retention time in HPLC. Among the derivatives, 3,3'',4''-tri-O-propionyl- and 3,4''-di-O-acetyl-3''-O-butyrylspiramycin I showed the highest therapeutic effect which was superior to acetylspiramycin. Structure activity relationships of spiramycins are discussed.

  1. Therapeutic cloning in the mouse (United States)

    Mombaerts, Peter


    Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the research literature on therapeutic cloning, strictly speaking, is comprised of only four articles, all in the mouse. The efficiency of derivation of embryonic stem cell lines via nuclear transfer is remarkably consistent among these reports. However, the efficiency is so low that, in its present form, the concept is unlikely to become widespread in clinical practice. PMID:12949262

  2. Clinical applications of therapeutic phlebotomy. (United States)

    Kim, Kyung Hee; Oh, Ki Young


    Phlebotomy is the removal of blood from the body, and therapeutic phlebotomy is the preferred treatment for blood disorders in which the removal of red blood cells or serum iron is the most efficient method for managing the symptoms and complications. Therapeutic phlebotomy is currently indicated for the treatment of hemochromatosis, polycythemia vera, porphyria cutanea tarda, sickle cell disease, and nonalcoholic fatty liver disease with hyperferritinemia. This review discusses therapeutic phlebotomy and the related disorders and also offers guidelines for establishing a therapeutic phlebotomy program.

  3. Alpbach Summer School - a unique learning experience (United States)

    Kern, K.; Aulinas, J.; Clifford, D.; Krejci, D.; Topham, R.


    The Alpbach Summer School is a ten-day program that provides a unique opportunity for young european science and engineering students, both undergraduate and graduate, to learn how to approach the entire design process of a space mission. The theme of the 2010 Summer School was "New Space Missions to Understand Climate Change", a current, challenging, very broad and complex topic. The program was established more than 35 years ago and is organised in two interrelated parts: a series of lectures held by renowned experts in the field (in the case of this specific year, climate change and space engineering experts) that provides a technical and scientific background for the workshops that follow, the core of the Summer School. For the workshops the students are split into four international, interdisciplinary teams of about 15 students. In 2010 every team had to complete a number of tasks, four in total: (1) identify climate change research gaps and design a space mission that has not yet been flown or proposed, (2) define the science objectives and requirements of the mission, (3) design a spacecraft that meets the mission requirements, which includes spacecraft design and construction, payload definition, orbit calculations, but also the satellite launch, operation and mission costs and (4) write up a short mission proposal and present the results to an expert review panel. Achieving these tasks in only a few days in a multicultural, interdisciplinary team represents a major challenge for all participants and provides an excellent practical learning experience. Over the course of the program, students do not just learn facts about climate change and space engineering, but scientists also learn from engineers and engineers from scientists. The participants have to deepen their knowledge in an often unfamiliar field, develop organisational and team-work skills and work under pressure. Moreover, teams are supported by team and roving tutors and get the opportunity to

  6. Therapeutic evaluation of omeprazole. (United States)

    Adams, M H; Ostrosky, J D; Kirkwood, C F


    The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage and administration of omeprazole are reviewed. Omeprazole, a substituted benzimidazole, has a unique site and mechanism of action because it inhibits the proton pump--i.e., hydrogen, potassium adenosine triphosphatase (H+,K+-ATPase)--and consequently blocks the final common step in the gastric acid secretory pathway. Omeprazole inhibits basal and histamine-, gastrin- and pentagastrin-stimulated gastric hydrochloric acid secretion. It produces a dose-dependent reduction in gastric acidity, gastric acid output, and gastric juice volume and has variable effects on pepsin secretion. Omeprazole has no documented effect on esophageal motility or lower esophageal sphincter pressure. Omeprazole is variably absorbed from the gastrointestinal tract, and food appears to decrease the rate, but not the extent, of drug absorption. The drug is approximately 95% bound to plasma proteins and is metabolized to inactive components that are enterohepatically or renally eliminated. Omeprazole is more effective (in most studies) than H2-receptor antagonists in treating duodenal ulcer, at least as effective in treating benign gastric ulcer, and more effective in treating reflux esophagitis. Omeprazole has been used successfully in patients with Zollinger-Ellison syndrome refractory to treatment with H2-receptor antagonists. Gastrointestinal complaints (nausea and diarrhea) are the most commonly reported adverse effects associated with omeprazole therapy. The most frequently reported laboratory abnormality occurring with omeprazole use is elevation of serum aspartate aminotransferase and alanine aminotransferase concentrations. Omeprazole will serve a valuable role in the management of gastrointestinal tract ulcers and hypersecretory conditions.

  8. Arachnoiditis ossificans and syringomyelia: A unique presentation (United States)

    Opalak, Charles F.; Opalak, Michael E.


    Background: Arachnoiditis ossificans (AO) is a rare disorder that was differentiated from leptomeningeal calcification by Kaufman and Dunsmore in 1971. It generally presents with progressive lower extremity myelopathy. Though the underlying etiology has yet to be fully described, it has been associated with various predisposing factors including vascular malformations, previous intradural surgery, myelograms, and adhesive arachnoiditis. Associated conditions include syringomyelia and arachnoid cyst. The preferred diagnostic method is noncontrast computed tomography (CT). Surgical intervention is still controversial and can include decompression and duroplasty or durotomy. Case Description: The authors report the case of a 62-year-old male with a history of paraplegia who presented with a urinary tract infection and dysautonomia. His past surgical history was notable for a C4–C6 anterior fusion and an intrathecal phenol injection for spasticity. A magnetic resonance image (MR) also demonstrated a T6-conus syringx. At surgery, there was significant ossification of the arachnoid/dura, which was removed. After a drain was placed in the syrinx, there was a significant neurologic improvement. Conclusion: This case demonstrates a unique presentation of AO and highlights the need for CT imaging when a noncommunicating syringx is identified. In addition, surgical decompression can achieve good results when AO is associated with concurrent compressive lesions. PMID:26693389

    Full Text Available Abstract Background Amyloid deposition in heart is a common occurrence in systemic amyloidosis. But localised valvular amyloid deposits are very uncommon. It was only in 1922 that the cases of valvular amyloidosis were reported. Then in 1980, Goffin et al reported another type of valvular amyloidosis, which he called the dystrophic valvular amyloidosis. We report a case of aortic valve amyloidosis which is different from the yet described valvular amyloidosis. Case presentation A 72 years old gentleman underwent urgent aortic valve replacement. Intraoperatively, a lesion was found attached to the inferior surface of his bicuspid aortic valve. Histopathology examination of the valve revealed that the lesion contained amyloid deposits, identified as AL amyloidosis. The serum amyloid A protein (SAP scan was normal and showed no evidence of systemic amyloidosis. The ECG and echocardiogram were not consistent with cardiac amyloidosis. Conclusion Two major types of cardiac amyloidosis have been described in literature: primary-myelomatous type (occurs with systemic amyolidosis, and senile type(s. Recently, a localised cardiac dystrophic valvular amyloidosis has been described. In all previously reported cases, there was a strong association of localised valvular amyloidosis with calcific deposits. Ours is a unique case which differs from the previously reported cases of localised valvular amyloidosis. In this case, the lesion was not associated with any scar tissue. Also there was no calcific deposit found. This may well be a yet unknown type of isolated valvular amyloidosis.

  10. Unique Ganglioside Recognition Strategies for Clostridial Neurotoxins

    Energy Technology Data Exchange (ETDEWEB)

    Benson, Marc A.; Fu, Zhuji; Kim, Jung-Ja P.; Baldwin, Michael R. (MCW); (UMC)


    Botulinum neurotoxins (BoNTs) and tetanus neurotoxin are the causative agents of the paralytic diseases botulism and tetanus, respectively. The potency of the clostridial neurotoxins (CNTs) relies primarily on their highly specific binding to nerve terminals and cleavage of SNARE proteins. Although individual CNTs utilize distinct proteins for entry, they share common ganglioside co-receptors. Here, we report the crystal structure of the BoNT/F receptor-binding domain in complex with the sugar moiety of ganglioside GD1a. GD1a binds in a shallow groove formed by the conserved peptide motif E ... H ... SXWY ... G, with additional stabilizing interactions provided by two arginine residues. Comparative analysis of BoNT/F with other CNTs revealed several differences in the interactions of each toxin with ganglioside. Notably, exchange of BoNT/F His-1241 with the corresponding lysine residue of BoNT/E resulted in increased affinity for GD1a and conferred the ability to bind ganglioside GM1a. Conversely, BoNT/E was not able to bind GM1a, demonstrating a discrete mechanism of ganglioside recognition. These findings provide a structural basis for ganglioside binding among the CNTs and show that individual toxins utilize unique ganglioside recognition strategies.

  11. Unique biosynthesis of sesquarterpenes (C35 terpenes). (United States)

    Sato, Tsutomu


    To the best of my knowledge, only 19 cyclic and 8 linear C35 terpenes have been identified to date, and no family name was assigned to this terpene class until recently. In 2011, it was proposed that these C35 terpenes should be called sesquarterpenes. This review highlights the biosynthesis of two kinds of sesquarterpenes (C35 terpenes) that are produced via cyclization of a linear C35 isoprenoid in Bacillus and Mycobacterium species. In Bacillus species, a new type of terpene cyclase that has no sequence homology with any known terpene synthases, as well as a bifunctional terpene cyclase that biosynthesizes two classes of cyclic terpenes with different numbers of carbons as natural products, have been identified. On the other hand, in Mycobacterium species, the first bifunctional Z-prenyltransferase has been found, but a novel terpene cyclase and a unique polyprenyl reductase remain unidentified. The identification of novel enzyme types should lead to the discovery of many homologous enzymes and their products including novel natural compounds. On the other hand, many enzymes responsible for the biosynthesis of natural products have low substrate specificities in vitro. Therefore, to find novel natural products present in organisms, the multifunctionality of enzymes in the biosynthetic pathway of natural products should be analyzed.

    The primary objective of this study was to evaluate the existing conditions and the stability of a mining site in which the unique features of seismicity, mining activity, hydrological conditions, geological con-ditions, environmental conditions, and future development plans were considered. In particular, the potential subsidence locations near the proposed construction site, the effects of mining boundary profile, and the influence scope of the mining activity on the neighboring areas were investigated using the finite element method. The study results indicate:(1) the overlying sandstone layer to the coal layer is the key to the stability of the mining roof; (2) the broken boundary has the most effect, followed by the arc boundary and linear boundary; (3) the safe distance from the mining boundary should be at least 400 m if the proposed structure is to be built near an active mining site. Other relevant engineering rec-ommendations are also proposed. The concluded results from this study may serve as a guide to other similar sites in the world.

    邓兆享; 张占书


    Objective To explore the value of detection of both EBV NA1 - IgA and VCA - IgA on the diagnosis and therapeutic effect of nasopharyngeal carcinoma ( NPC). Methods Samples from 124 cases of pretreatment and after treatment NPC and 173 healthy cases serum EBV antibodies NA1 - IgA and VCA -IgA were detected by enzyme -linked immnunosorbent assay (ELJSA). Results The sensitivity and accuracy for diagnosing NPC were 88.1% and 91. 2% for NA1 - IgA, 75. 8% and 84. 8% for VCA -IgA,and 97. 6% and 93. 3% for combined determination. No significant difference in the NPC patients different clinical stages (excluding the positive rates of clinical stage I) was found in serum EB-NA1 - IgA rA value and positive rates (P > 0. 05), but there was significant difference in the NPC patients different clinical stages (excluding the clinical stage IV) was found in serum EBVCA - IgA rA value and positive rates (P <0. 05). Conclusions Combined the determination of EBV NA1 - IgA and VCA -IgA could improve the diagnostic sensitivity and accuracy for early NPC. The rA value and positive rates of NA1 - IgA had no relationship with therapeutic effect of NPC. There was obvious relevance of the serum EBVCA - IgA rA value and positive rates with the therapeutic effect in NPC, It may be an important mark for monitoring therapeutic effect, the course of disease and the prognosis in NPC.%目的 探讨EB病毒NA1-IgA和VCA-IgA抗体与鼻咽癌的诊断和治疗效果的相关性.方法 使用酶联免疫吸附试验(ELISA)测定124例治疗前和治疗后鼻咽癌患者以及173例正常体检人群血清EB病毒NA1-IgA和VCA-IgA抗体.结果 单项检测时EB病毒检测的敏感性和准确性分别为:NA1-IgA 88.7%、91.2%,VCA-IgA75.8%、84.8%,两者联合检测的敏感性和准确性分别为97.6% 、93.3%.鼻咽癌患者血清EBNA1-IgA抗体rA值和阳性率在临床各期(Ⅱ期阳性率除外)治疗前后均无统计学差异(P>0.05),而鼻咽癌患者血清EBVCA-IgA抗体rA

  14. Purinergic Signalling: Therapeutic Developments

    Directory of Open Access Journals (Sweden)

    Geoffrey Burnstock


    Full Text Available Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990’s when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling. More recently, the focus has been on the pathophysiology and therapeutic potential. There was early recognition of the use of P1 receptor agonists for the treatment of supraventricular tachycardia and A2A receptor antagonists are promising for the treatment of Parkinson’s disease. Clopidogrel, a P2Y12 antagonist, is widely used for the treatment of thrombosis and stroke, blocking P2Y12 receptor-mediated platelet aggregation. Diquafosol, a long acting P2Y2 receptor agonist, is being used for the treatment of dry eye. P2X3 receptor antagonists have been developed that are orally bioavailable and stable in vivo and are currently in clinical trials for the treatment of chronic cough, bladder incontinence, visceral pain and hypertension. Antagonists to P2X7 receptors are being investigated for the treatment of inflammatory disorders, including neurodegenerative diseases. Other investigations are in progress for the use of purinergic agents for the treatment of osteoporosis, myocardial infarction, irritable bowel syndrome, epilepsy, atherosclerosis, depression, autism, diabetes, and cancer.

  15. Mitochondrial diseases: therapeutic approaches. (United States)

    DiMauro, Salvatore; Mancuso, Michelangelo


    Therapy of mitochondrial encephalomyopathies (defined restrictively as defects of the mitochondrial respiratory chain) is woefully inadequate, despite great progress in our understanding of the molecular bases of these disorders. In this review, we consider sequentially several different therapeutic approaches. Palliative therapy is dictated by good medical practice and includes anticonvulsant medication, control of endocrine dysfunction, and surgical procedures. Removal of noxious metabolites is centered on combating lactic acidosis, but extends to other metabolites. Attempts to bypass blocks in the respiratory chain by administration of electron acceptors have not been successful, but this may be amenable to genetic engineering. Administration of metabolites and cofactors is the mainstay of real-life therapy and is especially important in disorders due to primary deficiencies of specific compounds, such as carnitine or coenzyme Q10. There is increasing interest in the administration of reactive oxygen species scavengers both in primary mitochondrial diseases and in neurodegenerative diseases directly or indirectly related to mitochondrial dysfunction. Aerobic exercise and physical therapy prevent or correct deconditioning and improve exercise tolerance in patients with mitochondrial myopathies due to mitochondrial DNA (mtDNA) mutations. Gene therapy is a challenge because of polyplasmy and heteroplasmy, but interesting experimental approaches are being pursued and include, for example, decreasing the ratio of mutant to wild-type mitochondrial genomes (gene shifting), converting mutated mtDNA genes into normal nuclear DNA genes (allotopic expression), importing cognate genes from other species, or correcting mtDNA mutations with specific restriction endonucleases. Germline therapy raises ethical problems but is being considered for prevention of maternal transmission of mtDNA mutations. Preventive therapy through genetic counseling and prenatal diagnosis is

    Directory of Open Access Journals (Sweden)

    Vukićević Jelica


    Full Text Available Trichomoniasis is frequent, parasitic and sexually transmitted infection of genitourinary tract. It is treated by metronidazole (5-nitroimidazole according to protocol recommended by Center for Disease Control (CDC formerly called: Communicable Disease Center [19]. The resistance of Trichomonas vaginalis (TV strains to metronidazole (MND was described in USA in 1960, and later on in many European countries [8, 9, 10, 11, 12, 13]. In these cases, due to persistent trichomonas infection, it is necessary to repeat MND treatment with moderate modification of dose and/or length of its application. Nevertheless, oncogenic and toxic effects of MND have to be taken into consideration. OBJECT The aim of this study was to investigate and analyze the incidence of TV in STD and lower susceptibility of certain TV strains to MND were analyzed. MATERIAL AND METHODS In three-year period (1999-2001 612 patients (244 females and 368 males suspected of STD were examined clinically and microbiologically at the Institute of Dermatovenereology in Belgrade. The patients detected for TV were treated according to CDC protocol. The affected were considered cured if there was no manifest clinical infection, and no TV verified by microbiological test. Results TV was isolated in 216 patients (35.29 % of all subjects. Trichomonas infection was found in 90 (36.88 % out of 244 tested females and in 126 (32.34 % of 368 males. Clinically manifested infection, with extensive urethral and vaginal secretion, was recorded in 161 patients, while the asymptomatic form was found in 55 subjects. This result indicates the predominance of manifested trichomonas infections (75.54 % of cases. The difference of distribution of clinical forms of trichomoniasis, in relation to sex, was not statistically significant (c2=0.854; p>0.05. The patients with verified trichomonas infection were treated by metronidazole according to CDC protocol. The recommended therapeutical scheme consisted of three

    -participants and trial sponsors, and a survey of the participants. We found an organisation of clinical drug trials allowing extraordinary care relationships to form which makes trial participation attractive and allows information to flow more freely. However, the research-care intermingling generates moral concerns...... for those involved. We conceptualize these concerns as a productive moral friction resulting from research staff caring too much for patients. We identify three situations in which friction arises: when care-giving comes to replace specialist contact, when caring for individuals appears unfair...... for the collective, and when care motives may be doubted. We conclude that the presentation of the research-care tension as an ethical dilemma is misleading and even part of the problem that must be dealt with by those involved....

  18. Multifunctional Nanofibers towards Active Biomedical Therapeutics

    Directory of Open Access Journals (Sweden)

    Jaishri Sharma


    Full Text Available One-dimensional (1-D nanostructures have attracted enormous research interest due to their unique physicochemical properties and wide application potential. These 1-D nanofibers are being increasingly applied to biomedical fields owing to their high surface area-to-volume ratio, high porosity, and the ease of tuning their structures, functionalities, and properties. Many biomedical nanofiber reviews have focused on tissue engineering and drug delivery applications but have very rarely discussed their use as wound dressings. However, nanofibers have enormous potential as wound dressings and other clinical applications that could have wide impacts on the treatment of wounds. Herein, the authors review the main fabrication methods of nanofibers as well as requirements, strategies, and recent applications of nanofibers, and provide perspectives of the challenges and opportunities that face multifunctional nanofibers for active therapeutic applications.

  19. Synthetic Immunology: Hacking Immune Cells to Expand Their Therapeutic Capabilities. (United States)

    Roybal, Kole T; Lim, Wendell A


    The ability of immune cells to survey tissues and sense pathologic insults and deviations makes them a unique platform for interfacing with the body and disease. With the rapid advancement of synthetic biology, we can now engineer and equip immune cells with new sensors and controllable therapeutic response programs to sense and treat diseases that our natural immune system cannot normally handle. Here we review the current state of engineered immune cell therapeutics and their unique capabilities compared to small molecules and biologics. We then discuss how engineered immune cells are being designed to combat cancer, focusing on how new synthetic biology tools are providing potential ways to overcome the major roadblocks for treatment. Finally, we give a long-term vision for the use of synthetic biology to engineer immune cells as a general sensor-response platform to precisely detect disease, to remodel disease microenvironments, and to treat a potentially wide range of challenging diseases.

  20. Biotech drugs : biological therapeutic agents


    Grech, Godfrey; Fenech, Anthony


    The recent years has seen significant growth in a new therapeutic approach to the management of disease. Biological therapeutic agents, constitute a broad category of drugs, usually generated by recombinant techniques from living organisms. These therapies revolutionise the traditional approaches to drug design and development, and regulatory agencies have been swift in developing the necessary structures to ensure their optimal use.

  1. Some unique superconductive Properties of Cuprates (United States)

    Müller, K. A.


    Copper oxides are the only materials that show transition temperatures, Tc, above the boiling point of liquid nitrogen, with a maximum Tmc of 162 K under pressure. Their structure is layered, with one to several CuO2 planes, and upon hole doping, their transition temperature follows a dome-shaped curve with a maximum at Tmc. In the underdoped regime, i.e., below Tmc, a pseudogap T* is found, with T* always being larger than Tc, a property unique to the copper oxides [1]. In the superconducting state, Cooper pairs (two holes with antiparallel spins) are formed that exhibit coherence lengths on the order of a lattice distance in the CuO2 plane and one order of magnitude less perpendicular to it. Their macroscopic wave function is parallel to the CuO2 plane near 100% d at their surface, but only 75% d and 25 % s in the bulk, and near 100% s perpendicular to the plane in YBCO. There are two gaps with the same Tc [2]. As function of doping, the oxygen isotope effect is novel and can be quantitatively accounted for by a two-band vibronic theory [3] near Tmc, and underdoped below it till Tc = 0 with by a formula valid for (bi)polarons [4]. These cuprates are intrinsically heterogeneous in a dynamic way. In terms of quasiparticles, Jahn-Teller bipolarons are present at low doping, and aggregate upon cooling [1], so that probably ramified clusters and/or stripes are formed, leading over to a more Fermi-liquid-type behavior at large carrier concentrations above Tmc.

  2. Unique properties of Plasmodium falciparum porphobilinogen deaminase. (United States)

    Nagaraj, Viswanathan Arun; Arumugam, Rajavel; Gopalakrishnan, Bulusu; Jyothsna, Yeleswarapu Sri; Rangarajan, Pundi N; Padmanaban, Govindarajan


    The hybrid pathway for heme biosynthesis in the malarial parasite proposes the involvement of parasite genome-coded enzymes of the pathway localized in different compartments such as apicoplast, mitochondria, and cytosol. However, knowledge on the functionality and localization of many of these enzymes is not available. In this study, we demonstrate that porphobilinogen deaminase encoded by the Plasmodium falciparum genome (PfPBGD) has several unique biochemical properties. Studies carried out with PfPBGD partially purified from parasite membrane fraction, as well as recombinant PfPBGD lacking N-terminal 64 amino acids expressed and purified from Escherichia coli cells (DeltaPfPBGD), indicate that both the proteins are catalytically active. Surprisingly, PfPBGD catalyzes the conversion of porphobilinogen to uroporphyrinogen III (UROGEN III), indicating that it also possesses uroporphyrinogen III synthase (UROS) activity, catalyzing the next step. This obviates the necessity to have a separate gene for UROS that has not been so far annotated in the parasite genome. Interestingly, DeltaPfP-BGD gives rise to UROGEN III even after heat treatment, although UROS from other sources is known to be heat-sensitive. Based on the analysis of active site residues, a DeltaPfPBGDL116K mutant enzyme was created and the specific activity of this recombinant mutant enzyme is 5-fold higher than DeltaPfPBGD. More interestingly, DeltaPfPBGDL116K catalyzes the formation of uroporphyrinogen I (UROGEN I) in addition to UROGEN III, indicating that with increased PBGD activity the UROS activity of PBGD may perhaps become rate-limiting, thus leading to non-enzymatic cyclization of preuroporphyrinogen to UROGEN I. PfPBGD is localized to the apicoplast and is catalytically very inefficient compared with the host red cell enzyme.

  3. Metrics for antibody therapeutics development. (United States)

    Reichert, Janice M


    A wide variety of full-size monoclonal antibodies (mAbs) and therapeutics derived from alternative antibody formats can be produced through genetic and biological engineering techniques. These molecules are now filling the preclinical and clinical pipelines of every major pharmaceutical company and many biotechnology firms. Metrics for the development of antibody therapeutics, including averages for the number of candidates entering clinical study and development phase lengths for mAbs approved in the United States, were derived from analysis of a dataset of over 600 therapeutic mAbs that entered clinical study sponsored, at least in part, by commercial firms. The results presented provide an overview of the field and context for the evaluation of on-going and prospective mAb development programs. The expansion of therapeutic antibody use through supplemental marketing approvals and the increase in the study of therapeutics derived from alternative antibody formats are discussed.

    Weber-Dąbrowska, Beata; Jończyk-Matysiak, Ewa; Żaczek, Maciej; Łobocka, Małgorzata; Łusiak-Szelachowska, Marzanna; Górski, Andrzej


    Bacteriophages (phages), discovered 100 years ago, are able to infect and destroy only bacterial cells. In the current crisis of antibiotic efficacy, phage therapy is considered as a supplementary or even alternative therapeutic approach. Evolution of multidrug-resistant and pandrug-resistant bacterial strains poses a real threat, so it is extremely important to have the possibility to isolate new phages for therapeutic purposes. Our phage laboratory and therapy center has extensive experience with phage isolation, characterization, and therapeutic application. In this article we present current progress in bacteriophages isolation and use for therapeutic purposes, our experience in this field and its practical implications for phage therapy. We attempt to summarize the state of the art: properties of phages, the methods for their isolation, criteria of phage selection for therapeutic purposes and limitations of their use. Perspectives for the use of genetically engineered phages to specifically target bacterial virulence-associated genes are also briefly presented.

  6. Nursing therapeutics: Teaching student nurses care, compassion and empathy. (United States)

    Richardson, Cliff; Percy, Marcus; Hughes, Jane


    Debate continues regarding whether humanitarian values such as care and compassion can be taught or are innate in individuals who wish to become nurses. To undertake a discursive review of the literature on caring, compassion and empathy. To understand the teaching and learning issues associated with these concepts. To design and implement an Undergraduate Unit of study which addresses the development of caring, compassion and empathy in student nurses. MEDLINE, CINAHL, and a wide range of literature including books and governmental reports were used for a discursive narrative review. Caring, compassion and empathy are ill-defined; however healthcare users are clear that they know when nurses use skills and attitudes associated with these concepts. Evidence is available to show that caring, compassion and empathy can be taught and there are tools available to measure them in neophytes through their training. Central to the androgogical embedding of these concepts into nursing curricula is the development of therapeutic relationships. It is possible to develop materials to enable student nurses to learn how to care using compassion and empathy. Nursing therapeutics is a term devised to describe how student nurses can exploit the therapeutic potential of any patient contact especially when related to specific and routine nursing interventions. Muetzel's model for understanding therapeutic relationships is one framework that can be adopted to help student nurses to appreciate how to build patient relationships and encourage them to move towards therapeutic advantage using care, compassion and empathy.

  7. The therapeutic effects of Dead Sea mineral-based skincare


    Mallia, Alistair


    Dead Sea mineral-based skincare can be considered a unique part of the 'Sea' cosmetic trend. The sea as a natural source of healing is quite an old concept. In 1750 Richard Russel presented his thesis on the Therapeutic effect of seawater at Oxford. And in 1869 the term thalassotherapy or 'bringing together the sea and medicine' was coined by the French physican La Bonardier d'Arachon

    Bindra, Sanjit; Cefalu, William T


    Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first

  9. The Einstein constraints: uniqueness and non-uniqueness in the conformal thin sandwich approach

    CERN Document Server

    Baumgarte, T W; Pfeiffer, H P; Baumgarte, Thomas W.; Murchadha, Niall \\'{O}; Pfeiffer, Harald P.


    We study the appearance of multiple solutions to certain decompositions of Einstein's constraint equations. Pfeiffer and York recently reported the existence of two branches of solutions for identical background data in the extended conformal thin-sandwich decomposition. We show that the Hamiltonian constraint alone, when expressed in a certain way, admits two branches of solutions with properties very similar to those found by Pfeiffer and York. We construct these two branches analytically for a constant-density star in spherical symmetry, but argue that this behavior is more general. In the case of the Hamiltonian constraint this non-uniqueness is well known to be related to the sign of one particular term, and we argue that the extended conformal thin-sandwich equations contain a similar term that causes the breakdown of uniqueness.

    Morrow, John K; Du-Cuny, Lei; Chen, Lu; Meuillet, Emmanuelle J; Mash, Eugene A; Powis, Garth; Zhang, Shuxing


    The serine/threonine kinase Akt has proven to be a significant signaling target, involved in various biological functions. Because of its cardinal role in numerous cellular responses, Akt has been implicated in many human diseases, particularly cancer. It has been established that Akt is a viable and feasible target for anticancer therapeutics. Analysis of all Akt kinases reveals conserved homology for an N-terminal regulatory domain, which contains a pleckstrin-homology (PH) domain for cellular translocation, a kinase domain with serine/threonine specificity, and a C-terminal extension domain. These well defined regions have been targeted, and various approaches, including in silico methods, have been implemented to develop Akt inhibitors. In spite of unique techniques and a prolific body of knowledge surrounding Akt, no targeted Akt therapeutics have reached the market yet. Here we will highlight successes and challenges to date on the development of anticancer agents modulating the Akt pathway in recent patents as well as discuss the methods employed for this task. Special attention will be given to patents with focus on those discoveries using computer-aided drug design approaches.

    Oxidative stress significantly impacts multiple cellular pathways that can lead to the initiation and progression of varied disorders throughout the body. It therefore becomes imperative to elucidate the components and function of novel therapeutic strategies against oxidative stress to further clinical diagnosis and care. In particular, both the growth factor and cytokine erythropoietin (EPO) and members of the mammalian forkhead transcription factors of the O class (FoxOs) may offer the greatest promise for new treatment regimens since these agents and the cellular pathways they oversee cover a range of critical functions that directly influence progenitor cell development, cell survival and degeneration, metabolism, immune function, and cancer cell invasion. Furthermore, both EPO and FoxOs function not only as therapeutic targets, but also as biomarkers of disease onset and progression, since their cellular pathways are closely linked and overlap with several unique signal transduction pathways. However, biological outcome with EPO and FoxOs may sometimes be both unexpected and undesirable that can raise caution for these agents and warrant further investigations. Here we present the exciting as well as complicated role EPO and FoxOs possess to uncover the benefits as well as the risks of these agents for cell biology and clinical care in processes that range from stem cell development to uncontrolled cellular proliferation.

  13. Telomere and Telomerase Therapeutics in Cancer

    Directory of Open Access Journals (Sweden)

    Yucheng Xu


    Full Text Available Telomerase is a reverse transcriptase capable of utilizing an integrated RNA component as a template to add protective tandem telomeric single strand DNA repeats, TTAGGG, to the ends of chromosomes. Telomere dysfunction and telomerase reactivation are observed in approximately 90% of human cancers; hence, telomerase activation plays a unique role as a nearly universal step on the path to malignancy. In the past two decades, multiple telomerase targeting therapeutic strategies have been pursued, including direct telomerase inhibition, telomerase interference, hTERT or hTERC promoter driven therapy, telomere-based approaches, and telomerase vaccines. Many of these strategies have entered clinical development, and some have now advanced to phase III clinical trials. In the coming years, one or more of these new telomerase-targeting drugs may be expected to enter the pharmacopeia of standard care. Here, we briefly review the molecular functions of telomerase in cancer and provide an update about the preclinical and clinical development of telomerase targeting therapeutics.

    Zhongxing Liang

    Full Text Available BACKGROUND: Metastasis, the spread and growth of tumor cells to distant organ sites, represents the most devastating attribute and plays a major role in the morbidity and mortality of cancer. Inflammation is crucial for malignant tumor transformation and survival. Thus, blocking inflammation is expected to serve as an effective cancer treatment. Among anti-inflammation therapies, chemokine modulation is now beginning to emerge from the pipeline. CXC chemokine receptor-4 (CXCR4 and its ligand stromal cell-derived factor-1 (CXCL12 interaction and the resulting cell signaling cascade have emerged as highly relevant targets since they play pleiotropic roles in metastatic progression. The unique function of CXCR4 is to promote the homing of tumor cells to their microenvironment at the distant organ sites. METHODOLOGY/PRINCIPAL FINDINGS: We describe the actions of N,N'-(1,4-phenylenebis(methylenedipyrimidin-2-amine (designated MSX-122, a novel small molecule and partial CXCR4 antagonist with properties quite unlike that of any other reported CXCR4 antagonists, which was prepared in a single chemical step using a reductive amination reaction. Its specificity toward CXCR4 was tested in a binding affinity assay and a ligand competition assay using (18F-labeled MSX-122. The potency of the compound was determined in two functional assays, Matrigel invasion assay and cAMP modulation. The therapeutic potential of MSX-122 was evaluated in three different murine models for inflammation including an experimental colitis, carrageenan induced paw edema, and bleomycin induced lung fibrosis and three different animal models for metastasis including breast cancer micrometastasis in lung, head and neck cancer metastasis in lung, and uveal melanoma micrometastasis in liver in which CXCR4 was reported to play crucial roles. CONCLUSIONS/SIGNIFICANCE: We developed a novel small molecule, MSX-122, that is a partial CXCR4 antagonist without mobilizing stem cells, which can

  16. Characterizing the unique photochemical environment in China (United States)

    Liu, Z.; Wang, Y.; Gu, D.; Zhao, C.; Huey, L. G.; Stickel, R.; Liao, J.


    Recent observational evidence suggests that the atmospheric chemical system over China could be more complex than expected, possibly as a result of the rapid increasing anthropogenic emissions. During the CAREBeijing-2007 Experiment in August of 2007, up to 14 ppbv of peroxyacetyl nitrate (PAN, CH3C(O)OONO2) and 4.5 ppbv of glyoxal (CHOCHO) were observed, among the highest levels observed in the world in recent years. Elevated nitrous acid (HNO2) (~1.0 ppbv on average) was also observed in the early afternoon despite of the moderate amount of its precursors, i.e. nitrogen oxides (NOx=NO + NO2). We employ a 1-D photochemical model (REAM) to analyze the observations. The results indicate that reactive aromatics are the dominating source of PAN (55%-75%) and glyoxal (90%), and methylglyoxal is the major precursor of peroxy acetyl radical (50%). Downward transport from boundary layer is found to contribute ~50% of the PAN observed at surface. Photolysis of HNO2 is by far the largest primary OH source (more than 50%) throughout the daytime, and yet the fast formation rate of HNO2 inferred from the observations could not be explained by current known mechanisms. Detailed photochemical analysis is conducted to understand the controlling factors for O3 formation. O3 formation chemistry is strongly affected by aromatics and HNO2. By providing a large primary OH source, HNO2 leads to ~25% enhancement of the average O3 production rate, and aromatics contribute ~40% by serving as a major source of RO2 and HO2 radicals. Due to the large abundance of reactive hydrocarbons, O3 formation is generally NOx limited, although the sensitivity is low that a 50% reduction of NOx could only result in less than 25% reduction of the O3 production rate. Future research targeting HNO2 formation mechanism and emission sources of aromatics is necessary for better understanding the unique photochemical environment in China under significant anthropogenic impacts and the regional pollution

  18. Therapeutic modulation of microbiota-host metabolic interactions. (United States)

    Holmes, Elaine; Kinross, James; Gibson, Glenn R; Burcelin, Remy; Jia, Wei; Pettersson, Sven; Nicholson, Jeremy K


    The complex metabolic relationships between the host and its microbiota change throughout life and vary extensively between individuals, affecting disease risk factors and therapeutic responses through drug metabolism. Elucidating the biochemical mechanisms underlying this human supraorganism symbiosis is yielding new therapeutic insights to improve human health, treat disease, and potentially modify human disease risk factors. Therapeutic options include targeting drugs to microbial genes or co-regulated host pathways and modifying the gut microbiota through diet, probiotic and prebiotic interventions, bariatric surgery, fecal transplants, or ecological engineering. The age-associated co-development of the host and its microbiota provides a series of windows for therapeutic intervention from early life through old age.

  19. The Rise of Therapeutic Governing in Postsocialist China. (United States)

    Zhang, Li


    In this article, I explore how and why psychological intervention, often in the name of guanai (care), has gradually become a critical tool of managing the population and governing society in postsocialist China. Psychological counselors and experts are becoming a new form of authority, an indispensable part of creating and managing knowable, stable, and governable subjects for the military, the police, schools, and enterprises. 'Therapeutic governing' refers to the adoption of the therapeutic ethos, techniques, and care to improve the management of the work force and to help individuals cope with life in a rapidly changing society. I examine what drives local authorities to pursue this change, and how therapeutic governing takes on a different character and significance given China's unique path. I suggest that incorporating psychotherapeutic intervention into postsocialist governing can simultaneously produce disciplining and nurturing, repressive and unfettering effects in everyday life.

  20. Attitude Certainty and Attitudinal Advocacy: The Unique Roles of Clarity and Correctness. (United States)

    Cheatham, Lauren; Tormala, Zakary L


    When and why do people advocate on behalf of their attitudes? Past research suggests that attitude certainty is one important determinant. The current research seeks to provide more nuanced insight into this relationship by (a) exploring the unique roles of attitude clarity and attitude correctness, and (b) mapping clarity and correctness onto different forms of advocacy (sharing intentions and persuasion intentions). Across four studies, we find that correctness but not clarity plays an important role in promoting persuasion intentions, whereas both correctness and clarity help shape sharing intentions. Thus, this research unpacks the certainty-advocacy relation and helps identify experimental manipulations that uniquely drive persuasion and sharing intentions.

  7. Therapeutic alliance in a randomized clinical trial for bulimia nervosa. (United States)

    Accurso, Erin C; Fitzsimmons-Craft, Ellen E; Ciao, Anna; Cao, Li; Crosby, Ross D; Smith, Tracey L; Klein, Marjorie H; Mitchell, James E; Crow, Scott J; Wonderlich, Stephen A; Peterson, Carol B


    This study examined the temporal relation between therapeutic alliance and outcome in two treatments for bulimia nervosa (BN). Eighty adults with BN symptoms were randomized to 21 sessions of integrative cognitive-affective therapy (ICAT) or enhanced cognitive-behavioral therapy (CBT-E). Bulimic symptoms (i.e., frequency of binge eating and purging) were assessed at each session and posttreatment. Therapeutic alliance (Working Alliance Inventory) was assessed at Sessions 2, 8, 14, and posttreatment. Repeated-measures analyses using linear mixed models with random intercepts were conducted to determine differences in alliance growth by treatment and patient characteristics. Mixed-effects models examined the relation between alliance and symptom improvement. Overall, patients in both treatments reported strong therapeutic alliances. Regardless of treatment, greater therapeutic alliance between (but not within) subjects predicted greater reductions in bulimic behavior; reductions in bulimic behavior also predicted improved alliance. Patients with higher depression, anxiety, or emotion dysregulation had a stronger therapeutic alliance in CBT-E than ICAT, while those with more intimacy problems had greater improvement in therapeutic alliance in ICAT compared to CBT-E. Therapeutic alliance has a unique impact on outcome, independent of the impact of symptom improvement on alliance. Within- and between-subjects effects revealed that changes in alliance over time did not predict symptom improvement, but rather that individuals who had a stronger alliance overall had better bulimic symptom outcomes. These findings indicate that therapeutic alliance is an important predictor of outcome in the treatment of BN. (c) 2015 APA, all rights reserved).

  8. ROSAT Discovers Unique, Distant Cluster of Galaxies (United States)


    Brightest X-ray Cluster Acts as Strong Gravitational Lens Based on exciting new data obtained with the ROSAT X-ray satellite and a ground-based telescope at the ESO La Silla Observatory, a team of European astronomers [2] has just discovered a very distant cluster of galaxies with unique properties. It emits the strongest X-ray emission of any cluster ever observed by ROSAT and is accompanied by two extraordinarily luminous arcs that represent the gravitationally deflected images of even more distant objects. The combination of these unusual characteristics makes this cluster, now known as RXJ1347.5-1145, a most interesting object for further cosmological studies. DISCOVERY AND FOLLOW-UP OBSERVATIONS This strange cluster of galaxies was discovered during the All Sky Survey with the ROSAT X-ray satellite as a moderately intense X-ray source in the constellation of Virgo. It could not be identified with any already known object and additional ground-based observations were therefore soon after performed with the Max-Planck-Society/ESO 2.2-metre telescope at the La Silla observatory in Chile. These observations took place within a large--scale redshift survey of X-ray clusters of galaxies detected by the ROSAT All Sky Survey, a so-called ``ESO Key Programme'' led by astronomers from the Max-Planck-Institut fur Extraterrestrische Physik and the Osservatorio Astronomico di Brera. The main aim of this programme is to identify cluster X-ray sources, to determine the distance to the X-ray emitting clusters and to investigate their overall properties. These observations permitted to measure the redshift of the RXJ1347.5-1145 cluster as z = 0.45, i.e. it moves away from us with a velocity (about 106,000 km/sec) equal to about one-third of the velocity of light. This is an effect of the general expansion of the universe and it allows to determine the distance as about 5,000 million light-years (assuming a Hubble constant of 75 km/sec/Mpc). In other words, we see these

  10. Mentoring during residency education: a unique challenge for the surgeon? (United States)

    Pellegrini, Vincent D


    A mentor serves as role model, counselor, and advocate for an understudy or protégé. The art and science of mentoring have been investigated most thoroughly in the educational literature, yet there are unique situational and individual considerations in the surgical arena that may warrant special consideration. The general attributes of successful mentors are not foreign to academic surgeons but may require deliberate cultivation to optimize mentorship in the context of academic medicine. Moreover, the stages of productive mentoring may be counter to the learned adaptive behaviors and instinctive personality traits of some accomplished surgeon educators. Indeed, examples of failed mentorship are common in our medical centers and, specifically, in surgical training programs. The behavioral adaptation that supports surgical decision-making under conditions of incomplete data and unusual stress often devalues succession planning and derivation of satisfaction from the success of other members of the team. Accordingly, fostering effective mentoring relationships in academic surgery will require a concerted effort to develop appropriate behaviors conducive to the mentoring process. The personal and professional growth of our students as well as the succession planning for our specialty are dependent upon the successful creation of an environment conducive to mentoring in academic orthopaedics.

  11. The Universe as a Process of Unique Events

    CERN Document Server

    Cortês, Marina


    We describe a new class of models of quantum space-time based on energetic causal sets and show that under natural conditions space-time emerges from them. These are causal sets whose causal links are labelled by energy and momentum and conservation laws are applied at events. The models are motivated by principles we propose govern microscopic physics which posit a fundamental irreversibility of time. One consequence is that each event in the history of the universe has a distinct causal relationship to the rest; this requires a novel form of dynamics which an be applied to uniquely distinctive events. We hence introduce a new kind of deterministic dynamics for a causal set in which new events are generated from pairs of progenitor events by a rule which is based on extremizing the distinctions between causal past sets of events. This dynamics is asymmetric in time, but we find evidence from numerical simulations of a 1+1 dimensional model, that an effective dynamics emerges which restores approximate time r...

  12. Tumor microenvironment and therapeutic response. (United States)

    Wu, Ting; Dai, Yun


    The tumor microenvironment significantly influences therapeutic response and clinical outcome. Microenvironment-mediated drug resistance can be induced by soluble factors secreted by tumor or stromal cells. The adhesion of tumor cells to stromal fibroblasts or to components of the extracellular matrix can also blunt therapeutic response. Microenvironment-targeted therapy strategies include inhibition of the extracellular ligand-receptor interactions and downstream pathways. Immune cells can both improve and obstruct therapeutic efficacy and may vary in their activation status within the tumor microenvironment; thus, re-programme of the immune response would be substantially more beneficial. The development of rational drug combinations that can simultaneously target tumor cells and the microenvironment may represent a solution to overcome therapeutic resistance.

  13. Unique strategies for therapeutic gene transfer in haemophilia A and haemophilia BWFH State-of-the-Art Session on Therapeutic Gene Transfer Buenos Aires, Argentina. (United States)

    Montgomery, R R; Monahan, P E; Ozelo, M C


    Gene therapy of haemophilia has been initiated through a number of approaches including expression in muscle, liver and omental implanted fibroblasts, or i.v. injection of an expression construct under the control of a ubiquitous promoter. In all these approaches, the goal was to have factor VIII (FVIII) or factor IX (FIX) synthesized so that it restored the levels of the missing protein in blood. The three talks in this session are totally, or at least in part, directed at strategies that may be clinically effective even in the absence of correction of the missing plasma clotting factor, although the haematopoietic stem cell or blood outgrowth endothelial cell therapy could achieve plasma correction as well. Two of the approaches achieve localized coagulation factor expression without necessarily correcting the systemic defect--one is with synthesis of FVIII or FIX within the joint space and the other is with the local release of FVIII (or FIX) by platelets at the site of vascular injury. All of the three approaches have demonstrated efficacy in small animal models and are now the subject of larger animal studies. None has yet to progress to human trials.

    Wamsler, C; Schürmann, S; Dubbel, G; Blankenburg, M; Zernikow, B


    In the industrialized nations headache prevalence is increasing in children and adolescents. The nosologic classification determines the therapeutic strategy to follow. Three case reports illustrate the optimal cooperation of both a pediatric outpatient pain clinic and a pediatric psychosomatic pain clinic. We report on (1) a girl aged 2 years and 7 months with a 4-month history of headache episodes lasting about 15 min each with concomitant symptoms; (2) an 11-year-old boy with Schimmelpenning-Feuerstein-Mims syndrome, symptomatic focal epilepsy, psychomotor retardation, mild postinfectious internal hydrocephalus, and repeated heat-triggered episodes of right-sided headache beginning suddenly with a duration of 5-30 min and concomitant flush of his hemiface; and (3) a 12-year-old boy who for about 2 years has suffered from "migraine" 3 times a week, significantly impairing his quality of life. We discuss the patients' courses, diagnostic pitfalls, and therapeutic options. For the optimal treatment of children with headache not easily fitting into one of the categories, with significant comorbidity present, or if there is no adequate response to therapy conforming with guidelines, the help of an interdisciplinary pediatric pain clinic is invaluable.

  17. Discovery of a Structurally Unique Small Molecule that Inhibits Protein Synthesis (United States)

    Thakral, Durga; Tae, Hyun Seop


    Identifying and characterizing natural products and synthetic small molecules that inhibit biochemical processes such as ribosomal translation can lead to novel sources of molecular probes and therapeutics. The search for new antibiotics has been invigorated by the increasing burden of drug-resistant bacteria and has identified many clinically essential prokaryote-specific ribosome inhibitors. However, the current cohort of antibiotics is limited with regards to bacterial resistance mechanisms because of structural similarity within classes. From a high-throughput screen for translation inhibitors, we discovered a new compound, T6102, which inhibits bacterial protein synthesis in vitro, inhibits bacterial growth of Bacillus subtilis in vivo, and has a chemical structure that appears to be unique among known classes of translation-inhibiting antibiotics. T6102’s unique structure compared to current clinically-utilized antibiotics makes it an exciting new candidate for the development of next-generation antibiotics.

  18. Modes of therapeutic engagement. Part I: diplomacy and integrity. (United States)

    Billow, Richard M


    Our topic concerns strategies of therapeutic discourse, four relational modes of speaking and listening, adopted with and without awareness: diplomacy, integrity, sincerity, and authenticity. The four modes are offered as conceptual tools to help the therapist build therapeutic relationships, respond to challenges and impasses, and advance group process and insight. They are navigated to cement bonding, build trust, allow troubled relationships to evolve and resolve, and strengthen the abilities to think and relate. Presented in two separate articles, in Part I the topic and its relationship to truth and falsity is introduced, and the modes of diplomacy and integrity are described. The discussion continues, in Part II, where the focus is on sincerity and authenticity, and the interrelationship among the four modes and their differing functions in the totality of the clinical situation is illustrated.

  19. Counterconformity: an attribution model of adolescents' uniqueness-seeking behaviors in dressing. (United States)

    Ling, I-Ling


    This article explores how an attribution model will illustrate uniqueness-seeking behavior in dressing in the Taiwanese adolescent subculture. The study employed 443 senior high school students. Results show that the tendency of uniqueness-seeking behavior in dressing is moderate. However, using cluster analysis to segment the counterconformity behavior of the subjects, the study demonstrates that there are two conspicuous types of segmentation "markets": rubber stamp and self-determined. The attribution models investigate the susceptibilities to informational and normative influence which have different direction impacts and weights on the adolescents' counterconformity behavior. More interestingly, path analyses indicate that consumer self-confidence mediates the relationship between informational influence and counterconformity behavior only on the rubber stamp type. This study then discusses how the adolescent consumers' need for uniqueness could be used in better understanding consumer behavior and the role consumption plays in their expression of identity.

  20. Therapeutic Plasma Transfusion in Bleeding Patients: A Systematic Review. (United States)

    Levy, Jerrold H; Grottke, Oliver; Fries, Dietmar; Kozek-Langenecker, Sibylle


    Plasma products, including fresh frozen plasma, are administered extensively in a variety of settings from massive transfusion to vitamin K antagonist reversal. Despite the widespread use of plasma as a hemostatic agent in bleeding patients, its effect in comparison with other available choices of hemostatic therapies is unclear. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PubMed Central, and databases of ongoing trials for randomized controlled trials that assessed the efficacy and/or safety of therapeutic plasma as an intervention to treat bleeding patients compared with other interventions or placebo. Of 1243 unique publications retrieved in our initial search, no randomized controlled trials were identified. Four nonrandomized studies described the effect of therapeutic plasma in bleeding patients; however, data gathered from these studies did not allow for comparison with other therapeutic interventions primarily as a result of the low number of patients and the use of different (or lack of) comparators. We identified two ongoing trials investigating the efficacy and safety of therapeutic plasma, respectively; however, no data have been released as yet. Although plasma is used extensively in the treatment of bleeding patients, evidence from randomized controlled trials comparing its effect with those of other therapeutic interventions is currently lacking.

  1. Sleep-time blood pressure: Unique sensitive prognostic marker of vascular risk and therapeutic target for prevention. (United States)

    Hermida, Ramón C; Ayala, Diana E; Smolensky, Michael H; Fernández, José R; Mojón, Artemio; Portaluppi, Francesco


    Correlation between blood pressure (BP) and target organ damage, vascular risk, and long-term patient prognosis is stronger for measurements derived from around-the-clock ambulatory BP monitoring (ABPM) than in-clinic daytime ones. Numerous studies consistently substantiate the asleep BP mean is both an independent and much better predictor of cardiovascular disease (CVD) risk than either the awake or 24 h means. Elevated sleep-time BP, i.e., sleep-time hypertension, which can only be diagnosed by around-the-clock ABPM, is much more common than suspected, not only in patients with sleep disorders, but, among others, in those who are elderly or have type 2 diabetes, chronic kidney disease, or resistant hypertension. Hence, medical guidelines increasingly recommend ABPM to make the accurate differential diagnosis of hypertension versus normotension and recognize the marked clinical importance of adequate management of sleep-time BP. The ingestion time, according to circadian rhythms, of hypertension medications of six different classes and their combinations significantly impacts their beneficial, particularly on sleep-time BP control, and/or adverse effects. The MAPEC (monitorización ambulatoria para predicción de eventos cardiovasculares (i.e., ambulatory blood pressure monitoring for prediction of cardiovascular events)) study was the first prospective randomized treatment-time investigation designed to test the worthiness of bedtime chronotherapy with ≥1 conventional hypertension medications to specifically target attenuation of asleep BP. This 5.6 y median follow-up outcomes trial found the bedtime chronotherapy strategy most advantageous, resulting in the differential reduction of total CVD events by 61% and decrease of major CVD events - CVD death, myocardial infarction, and ischemic and hemorrhagic stroke - by 67%.

  2. Relational mindfulness, spirituality, and the therapeutic bond. (United States)

    Falb, Melissa D; Pargament, Kenneth I


    Mindfulness training, which emphasizes deliberate non-judgmental attention to present moment experiences, has become increasingly mainstream over the past several decades. With accumulating evidence for the physical and mental health benefits of mindfulness, it has been integrated into medical and psychological treatments and is increasingly accepted in the fields of psychology and psychiatry. However, several elements of mindfulness practice which potentially contribute to its benefits have been largely neglected. These include the connections between mindfulness, interpersonal relationships, spirituality, and the psychotherapeutic alliance. The emerging concept of "relational mindfulness" focuses attention on the oft-neglected interpersonal aspects of mindfulness practices. Relational mindfulness is potentially relevant to the psychotherapeutic process, due to its cultivation of the types of qualities that enhance the therapeutic relationship, including warmth, empathy, curiosity, acceptance, self-attunement, and emotional intelligence. In addition, mindfulness practices, especially relational ones, can contribute to the development of spiritual qualities, such as transcendence, boundlessness, ultimacy, and interconnectedness. Several recent studies suggest that meditation/mindfulness interventions may be explained and or enhanced by an emphasis on spiritual components. In this paper, we suggest that focusing on the oft-neglected relational and spiritual aspects of mindfulness practice has the potential to deepen its benefits, especially within the context of the psychotherapeutic relationship.

    Law, Colleen Ashleigh


    The purpose of this study was to investigate the relationship between psychological wellbeing and uniqueness seeking behaviour. Early research in psychology has primarily followed a pathogenic approach, focusing on the way in which stressful life events predispose an individual to negative health outcomes. More recently a number of theorists and researchers have adopted a salutogenic approach, which refers to the origins of physical and mental health and explores the factors th...

  5. The public library as therapeutic landscape: a qualitative case study. (United States)

    Brewster, Liz


    The idea of the therapeutic landscape has been widely used to describe the relationship between place and improvements in mental health. This paper uses data from a qualitative study conducted with people with mental health problems to outline the role of the public library as a therapeutic landscape. It situates the public library as a space that is simultaneously familiar and welcoming, comforting and calming, and empowering. Further, the paper reflects on the impact of proposed library closures in light of these previously hidden benefits, thinking about the library's role as an environment and not as a service provider.

  6. Comparative analysis of human and bovine protein kinases reveals unique relationship and functional diversity

    Directory of Open Access Journals (Sweden)

    Nuzhat N. Kabir


    Full Text Available Reversible protein phosphorylation by protein kinases and phosphatases is a common event in various cellular processes. The eukaryotic protein kinase superfamily, which is one of the largest superfamilies of eukaryotic proteins, plays several roles in cell signaling and diseases. We identified 482 eukaryotic protein kinases and 39 atypical protein kinases in the bovine genome, by searching publicly accessible genetic-sequence databases. Bovines have 512 putative protein kinases, each orthologous to a human kinase. Whereas orthologous kinase pairs are, on an average, 90.6% identical, orthologous kinase catalytic domain pairs are, on an average, 95.9% identical at the amino acid level. This bioinformatic study of bovine protein kinases provides a suitable framework for further characterization of their functional and structural properties.

  9. The relationship in motivational interviewing. (United States)

    Moyers, Theresa B


    The therapeutic relationship in motivational interviewing is hypothesized to have both a direct impact on client outcomes as well as facilitating the emergence of client language in favor of change. The nature of this relationship is characterized by empathy, partnership, and support of the client's autonomy commonly called the spirit of the method. This article explores the implications of this spirit on the practice and understanding of motivational interviewing, including common misconceptions attributable to a misunderstanding of the role of the relationship.

  10. Autophagy: An Exposing Therapeutic Target in Atherosclerosis. (United States)

    Luo, Yun; Lu, Shan; Zhou, Ping; Ai, Qi-Di; Sun, Gui-Bo; Sun, Xiao-Bo


    Autophagy is an evolutionarily conserved catabolic process whereby the cytoplasmic contents of a cell are sequestered within autophagosomes through a lysosome-dependent pathway. Increasing evidence shows that this process is of great importance in a wide range of diseases, including atherosclerosis (AS). Autophagy can be modulated in advanced AS plaques by cytokines, reactive lipids, lipopolysaccharides, advanced glycation end products, and microRNAs. Autophagy exerts both protective and detrimental functions in vascular disorders. However, despite an increasing interest in autophagy, it remains an underestimated and overlooked phenomenon in AS. Therefore, the precise role of autophagy and its relationship with apoptosis need to be described. This review highlights recent findings on the autophagy activities and signaling pathways in endothelial cells, macrophages, and smooth muscle cells that are accompanied by apoptosis in AS. We conclude with recent studies on autophagy modulation as a new therapeutic approach to treat AS.

  11. Treating troubled families: therapeutic scenario in India. (United States)

    Thomas, Bino


    India, a country of diverse cultures, languages, life styles, and ethnicities, is becoming a land of economic change, political stability, technological advancement, and changing traditional structures of relationships as well as health consciousness. Being known for its ancient traditions, rituals, religious orientation, spiritual outlook and folk beliefs, Indian families attempt to continue certain healthy and traditional elements such as warmth, strong bond, hierarchy, extended support, cultural orientation, shared values and time, tolerance, respect for the aged and inculcation of religious teachings and traditions in families. These factors, or practices, in fact have strong therapeutic value in supplementing the growth and development of individuals in the family system in spite of its transitional position. This paper deals with the review of family-based mental health services and focuses on the changing trends of those practices in India and the advancement of Indian families in their engaging ability with mentally ill members as well as with the treating team.

  14. Two concepts of therapeutic optimism (United States)

    Jansen, Lynn A


    Researchers and ethicists have long been concerned about the expectations for direct medical benefit expressed by participants in early phase clinical trials. Early work on the issue considered the possibility that participants misunderstand the purpose of clinical research or that they are misinformed about the prospects for medical benefit from these trials. Recently, however, attention has turned to the possibility that research participants are simply expressing optimism or hope about their participation in these trials. The ethical significance of this therapeutic optimism remains unclear. This paper argues that there are two distinct phenomena that can be associated with the term ‘therapeutic optimism’—one is ethically benign and the other is potentially worrisome. Distinguishing these two phenomena is crucial for understanding the nature and ethical significance of therapeutic optimism. The failure to draw a distinction between these phenomena also helps to explain why different writers on the topic often speak past one another. PMID:21551464

  15. Therapeutic and recreational methadone cardiotoxicity. (United States)

    Lusetti, Monia; Licata, Manuela; Silingardi, Enrico; Reggiani Bonetti, Luca; Palmiere, Cristian


    Several classes of drugs have been associated with an increased risk of cardiovascular disease and occurrence of arrhythmias potentially involved in sudden deaths in chronic users even at therapeutic doses. The study presented herein focuses on pathological changes involving the heart possibly due to methadone use. 60 cases were included in the study in total and were divided into three groups (therapeutic methadone users: 20 cases, recreational methadone users: 20 cases, and sudden death group in subjects who had never taken methadone: 20 cases). Autopsies, histology, biochemistry and toxicology were performed in all cases. Macroscopic and microscopic investigation results in therapeutic methadone users were similar to those observed in sudden, unexpected deaths in non-methadone users. In recreational methadone consumers, macroscopic and microscopic examination of the heart failed to provide results consistent with acute or chronic myocardial or coronary damage, thereby corroborating the hypothesis of death most likely following respiratory depression.

  16. Potential therapeutic applications of biosurfactants. (United States)

    Gudiña, Eduardo J; Rangarajan, Vivek; Sen, Ramkrishna; Rodrigues, Lígia R


    Biosurfactants have recently emerged as promising molecules for their structural novelty, versatility, and diverse properties that are potentially useful for many therapeutic applications. Mainly due to their surface activity, these molecules interact with cell membranes of several organisms and/or with the surrounding environments, and thus can be viewed as potential cancer therapeutics or as constituents of drug delivery systems. Some types of microbial surfactants, such as lipopeptides and glycolipids, have been shown to selectively inhibit the proliferation of cancer cells and to disrupt cell membranes causing their lysis through apoptosis pathways. Moreover, biosurfactants as drug delivery vehicles offer commercially attractive and scientifically novel applications. This review covers the current state-of-the-art in biosurfactant research for therapeutic purposes, providing new directions towards the discovery and development of molecules with novel structures and diverse functions for advanced applications.

  17. Bone-seeking therapeutic radiopharmaceuticals

    Directory of Open Access Journals (Sweden)

    Srivastava Suresh C.


    Full Text Available Bone-seeking therapeutic radiopharmaceuticals are utilized on the basis of the radionuclide?s particulate emissions (primarily low to intermediate beta emission. The requirements therefore are different from those of bone imaging agents that consist mainly of short-lived single photon emitters. Lately, the therapeutic bone seeking radiopharmaceuticals have attained increasing importance due to their potential role in alleviating pain from osseous metastases in cancer patients, for the treatment of joint pain resulting from inflamed synovium (radiosynoviorthesis, or radiosynovectomy, or from various other forms of arthritic disease. There is, however, a paucity of published data on the bio-pharmacokinetics of these agents when used following intravenous administration for bone pain palliation. This paper will briefly review and summarize the presently available chemical and biopharmacokinetic information on the various clinically approved as well as experimental bone-localizing therapeutic radiopharmaceuticals, and make projections on their clinical application for the treatment of primary/metastatic cancer in bone.

    AIM To observe the clinical effect of self-made Jinhuang Pingan Decoction (JHPAD) in treating intestinaladhesion.METHODS Among 580 cases of intestinal adhesion, 492 cases were treated with oral JHPAD alone; 88cases with incomplete intestinal obstruction were treated by gastrointestinal decompression, then givingconcentrated JHPAD through the GI tube as well as fluid replacement and anti-inflammation therapy.RESULTS Among 580 cases, 302 cases were cured, 232 cases, improved and 46 cases had no change, thetotal effective rate was 92.1%. In 492 patients treated with JHPAD alone, 264 cases had obvious effect, 202cases were improved and 26 cases had no effect, the total effective rate was 94.7%, and the corresponingresults in 88 cases treated with JHPAD and gastrointestinal decompression were 39 cases, 29 cases, 20 casesand 77.3% respectively. In addition, there was close relationship between the therapeutic efficacy anddisease course, and had significant statistical difference in therapeutic efficacy with the disease course of lessthan 30 d or over 12 m (x2=87.32, P<0.0001).CONCLUSION JHPAD has the effect of clearing heat, detoxication, anti-inflammation, relieving edema,analgesia, hemostasis and anti-adhesion in the treatment of intestinal adhesion. It has a satisfactory efficacyand no toxic reaction, so it is worthy to popularize in clinical practice.

  19. Dysaccommodation of the stomach: therapeutic nirvana? (United States)

    Bisschops, R; Tack, J


    Functional dyspepsia (FD) is a highly prevalent gastrointestinal disorder and has a complex pathophysiology. Impaired fundic relaxation in response to a meal is present in 40% of patients with FD. This review focuses on impaired gastric accommodation of the stomach as a pathophysiological mechanism and the possible therapeutic targets that can be derived from the current knowledge of the neuroregulation of the accommodation reflex. First the different means of gastric accommodation assessment are described and the relationship between symptoms and impaired gastric accommodation. The different therapeutic options are subsequently discussed in view of their molecular target, based on the different receptor subtypes involved in the accommodation reflex. Although impaired gastric accommodation is highly prevalent in dyspeptic patients and basic knowledge about the accommodation reflex enables to develop pathophysiologically targeted therapies, it is unlikely that therapies aimed at dysaccommodation of the stomach will lead to symptom relief in all dyspeptic patients. A major challenge is the development of methods that readily identify impaired accommodation in clinical practice.

  20. The EMT spectrum and therapeutic opportunities. (United States)

    Voon, Dominic C; Huang, Ruby Y; Jackson, Rebecca A; Thiery, Jean P


    Carcinomas are phenotypically arrayed along an epithelial-mesenchymal transition (EMT) spectrum, a developmental program currently exploited to understand the acquisition of drug resistance through a re-routing of growth factor signaling. This review collates the current approaches employed in developing therapeutics against cancer-associated EMT, and provides an assessment of their respective strengths and drawbacks. We reflect on the close relationship between EMT and chemoresistance against current targeted therapeutics, with a special focus on the epigenetic mechanisms that link these processes. This prompts the hypothesis that carcinoma-associated EMT shares a common epigenetic pathway to cellular plasticity as somatic cell reprogramming during tissue repair and regeneration. Indeed, their striking resemblance suggests that EMT in carcinoma is a pathological adaptation of an intrinsic program of cellular plasticity that is crucial to tissue homeostasis. We thus propose a revised approach that targets the epigenetic mechanisms underlying pathogenic EMT to arrest cellular plasticity regardless of upstream cancer-driving mutations. © 2017 The Authors.

  1. Uniqueness of the differential Mueller matrix of uniform homogeneous media. (United States)

    Devlaminck, Vincent; Ossikovski, Razvigor


    We show that the differential matrix of a uniform homogeneous medium containing birefringence may not be uniquely determined from its Mueller matrix, resulting in the potential existence of an infinite set of elementary polarization properties parameterized by an integer parameter. The uniqueness depends on the symmetry properties of a special differential matrix derived from the eigenvalue decomposition of the Mueller matrix. The conditions for the uniqueness of the differential matrix are identified, physically discussed, and illustrated in examples from the literature.

  3. Therapeutic effects of low radiation doses

    Energy Technology Data Exchange (ETDEWEB)

    Trott, K.R. (Dept. of Radiation Biology, St. Bartholomew' s Medical College, London (United Kingdom))


    This editorial explores the scientific basis of radiotherapy with doses of < 1 Gy for various non-malignant conditions, in particular dose-effect relationships, risk-benefit considerations and biological mechanisms. A review of the literature, particularly clinical and experimental reports published more than 50 years ago was conducted to clarify the following problems. 1. The dose-response relationships for the therapeutic effects on three groups of conditions: non-malignant skin disease, arthrosis and other painful degenerative joint disorders and anti-inflammatory radiotherapy; 2. risks after radiotherapy and after the best alternative treatments; 3. the biological mechanisms of the different therapeutic effects. Radiotherapy is very effective in all three groups of disease. Few dose-finding studies have been performed, all demonstrating that the optimal doses are considerable lower than the generally recommended doses. In different conditions, risk-benefit analysis of radiotherapy versus the best alternative treatment yields very different results: whereas radiotherapy for acute postpartum mastitis may not be justified any more, the risk-benefit ratio of radiotherapy of other conditions and particularly so in dermatology and some anti-inflammatory radiotherapy appears to be more favourable than the risk-benefit ratio of the best alternative treatments. Radiotherapy can be very effective treatment for various non-malignant conditions such as eczema, psoriasis, periarthritis humeroscapularis, epicondylitis, knee arthrosis, hydradenitis, parotitis and panaritium and probably be associated with less acute and long-term side effects than similarly effective other treatments. Randomized clinical studies are required to find the optimal dosage which, at present, may be unnecessarily high.

  4. Theorems on Positive Data: On the Uniqueness of NMF

    Directory of Open Access Journals (Sweden)

    Hans Laurberg


    Full Text Available We investigate the conditions for which nonnegative matrix factorization (NMF is unique and introduce several theorems which can determine whether the decomposition is in fact unique or not. The theorems are illustrated by several examples showing the use of the theorems and their limitations. We have shown that corruption of a unique NMF matrix by additive noise leads to a noisy estimation of the noise-free unique solution. Finally, we use a stochastic view of NMF to analyze which characterization of the underlying model will result in an NMF with small estimation errors.

  5. Therapeutics for Equine Endocrine Disorders. (United States)

    Durham, Andy E


    Equine endocrine disease is commonly encountered by equine practitioners. Pituitary pars intermedia dysfunction (PPID) and equine metabolic syndrome (EMS) predominate. The most logical therapeutic approach in PPID uses dopamine agonists; pergolide mesylate is the most common. Bromocryptine and cabergoline are alternative drugs with similar actions. Drugs from other classes have a poor evidence basis, although cyproheptadine and trilostane might be considered. EMS requires management changes as the primary approach; reasonable justification for use of drugs such as levothyroxine and metformin may apply. Therapeutic options exist in rare cases of diabetes mellitus, diabetes insipidus, hyperthyroidism, and critical illness-related corticosteroid insufficiency. Copyright © 2016 Elsevier Inc.

  6. Who needs a therapeutic phlebotomy? (United States)

    Antle, Emily Amy


    Many oncology practices treat patients with benign and malignant hematologic diagnoses. As a result, oncology nurses often are required to care for these patients. One common procedure nurses perform is therapeutic phlebotomy, where about 500 ml of blood is removed through a large-bore needle over 15-30 minutes. The procedure is ordered as a treatment for hereditary hemochromatosis, polycythemia vera, and secondary polycythemia. Before initiating the procedure, nurses must be aware of a patient's diagnosis, baseline hemoglobin, hematocrit, ferritin, and therapeutic end points. Reviewing these diagnoses will help nurses understand why phlebotomy is an important part of treatment.

  8. Evidence Based Digoxin Therapeutic Monitoring - A Lower and Narrower Therapeutic Range

    Directory of Open Access Journals (Sweden)



    Full Text Available Cardiac glycosides have been used for congestive heart failure and certain cardiac arrhythmias for more than 200 years. Despite the introduction of a variety of new classes of drugs for the management of heart failure, specifically angiotensin-converting enzyme (ACE inhibitors, b-adrenergic antagonists (bblockers, and the aldosterone antagonist spironolactone, digoxin continues to have an important role in long-term outpatient management. However, a narrow margin exists between therapeutic and toxic doses of digoxin, resulting in a high incidence of digoxin toxicity in clinical practice.A wide variety of placebo-controlled clinical trials have unequivocally shown that treatment with digoxin can improve symptoms, quality of life, and exercise tolerance in patients with mild, moderate, or severe heart failure. The clinical relevance of digoxin therapeutic monitoring is also proved but the SDC (Serum Digoxin Conentrations required for optimal clinical efficacy and acceptable toxicity remains controversial. In the last years, international guidelines recommend 1.2 ng/mL as acceptable high level.In this bibliographic synthesis, we aim to collect pertinent informations from MedLine database about exposure-effect relationship in order to assess the evidence level scientific of new digoxin therapeutic monitoring. 

  9. Goethe's anxieties, depressive episodes and (self-)therapeutic strategies: a contribution to method integration in psychotherapy. (United States)

    Holm-Hadulla, Rainer M


    In psychiatry and psychotherapy, abstract scientific principles need to be exemplified by narrative case reports to gain practical precision. Goethe was one of the most creative writers, productive scientists, and effective statesmen that ever lived. His descriptions of feelings, emotions, and mental states related to anxieties, depressive episodes, dysthymia, and creativity are unique in their phenomenological precision and richness. His life and work can thus serve as an excellent example enhancing our understanding of the relationship between anxiety, depression and creativity. Furthermore, he described (self-)therapeutic strategies that reinforce and refine modern views. Goethe's self-assessments in his works and letters, and the descriptions by others are analyzed under the perspective of current psychiatric classification. His therapeutic techniques and recommendations are compared with cognitive-behavioral, psychodynamic, and existential psychotherapy to amplify modern concepts of psychotherapy. From a scientific perspective, several distinctive depressive episodes can be diagnosed in Goethe's life. They were characterized by extended depressive moods, lack of drive, and loss of interest and self-esteem combined with social retreat. Goethe displayed diffuse and phobic anxieties as well as dysthymia. His (self-)therapeutic strategies were: (a) the systematic use of helping alliances, (b) behavioral techniques, (c) cognitive reflection on meanings and beliefs, (d) psychodynamic and psychoanalytic remembering, repeating, and working through, and (e) existential striving for self-actualization, social commitment, meaning, and creativity. In Goethe's life, creative incubation, illumination, and elaboration appear to have been associated with psychic instability and dysthymia, sometimes with depressive episodes in a clinical sense. On the one hand, his creative work was triggered by anxieties, dysthymia, and depressive moods. On the other hand, his creativity

  10. Genome comparison without alignment using shortest unique substrings

    Directory of Open Access Journals (Sweden)

    Möller Friedrich


    Full Text Available Abstract Background Sequence comparison by alignment is a fundamental tool of molecular biology. In this paper we show how a number of sequence comparison tasks, including the detection of unique genomic regions, can be accomplished efficiently without an alignment step. Our procedure for nucleotide sequence comparison is based on shortest unique substrings. These are substrings which occur only once within the sequence or set of sequences analysed and which cannot be further reduced in length without losing the property of uniqueness. Such substrings can be detected using generalized suffix trees. Results We find that the shortest unique substrings in Caenorhabditis elegans, human and mouse are no longer than 11 bp in the autosomes of these organisms. In mouse and human these unique substrings are significantly clustered in upstream regions of known genes. Moreover, the probability of finding such short unique substrings in the genomes of human or mouse by chance is extremely small. We derive an analytical expression for the null distribution of shortest unique substrings, given the GC-content of the query sequences. Furthermore, we apply our method to rapidly detect unique genomic regions in the genome of Staphylococcus aureus strain MSSA476 compared to four other staphylococcal genomes. Conclusion We combine a method to rapidly search for shortest unique substrings in DNA sequences and a derivation of their null distribution. We show that unique regions in an arbitrary sample of genomes can be efficiently detected with this method.

In most cases, these diseases have a bad prognosis without treatment. Therapeutic apheresis in combination with immunosuppressive therapies has led to a steady increase in survival rates over the last 35 years. Here we provide an overview of the most important pathogenic aspects indicating that therapeutic apheresis can be a supportive therapy in some systemic autoimmune diseases, such as systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, and inflammatory eye disease. With the introduction of novel and effective biologic agents, therapeutic apheresis is indicated only in severe cases, such as in rapid progression despite immunosuppressive therapy and/or biologic agents, and in patients with renal involvement, acute generalized vasculitis, thrombocytopenia, leucopenia, pulmonary, cardiac, or cerebral involvement. In mild forms of autoimmune disease, treatment with immunosuppressive therapies and/or biologic agents seems to be sufficient. The prognosis of autoimmune diseases with varying organ manifestations has improved considerably in recent years, due in part to very aggressive therapy schemes.

    The cardiac microenvironment includes cardiomyocytes, fibroblasts and macrophages, which regulate remodeling after myocardial infarction (MI). Targeting this microenvironment is a novel therapeutic approach for MI. We found that the natural compound derivative, BIO ((2'Z,3'E)-6-Bromoindirubin-3'-oxime) modulated the cardiac microenvironment to exert a therapeutic effect on MI. Using a series of co-culture studies, BIO induced proliferation in cardiomyocytes and inhibited proliferation in cardiac fibroblasts. BIO produced multiple anti-fibrotic effects in cardiac fibroblasts. In macrophages, BIO inhibited the expression of pro-inflammatory factors. Significantly, BIO modulated the molecular crosstalk between cardiac fibroblasts and differentiating macrophages to induce polarization to the anti-inflammatory M2 phenotype. In the optically transparent zebrafish-based heart failure model, BIO induced cardiomyocyte proliferation and completely recovered survival rate. BIO is a known glycogen synthase kinase-3β inhibitor, but these effects could not be recapitulated using the classical inhibitor, lithium chloride; indicating novel therapeutic effects of BIO. We identified the mechanism of BIO as differential modulation of p27 protein expression and potent induction of anti-inflammatory interleukin-10. In a rat MI model, BIO reduced fibrosis and improved cardiac performance. Histological analysis revealed modulation of the cardiac microenvironment by BIO, with increased presence of anti-inflammatory M2 macrophages. Our results demonstrate that BIO produces unique effects in the cardiac microenvironment to promote recovery post-MI.

    Dutta, A.; Veldhuis, Raymond N.J.; Spreeuwers, Lieuwe Jan


    In Biometrics, facial uniqueness is commonly inferred from impostor similarity scores. In this paper, we show that such uniqueness measures are highly unstable in the presence of image quality variations like pose, noise and blur. We also experimentally demonstrate the instability of a recently

    A view of the mutual dependence between libraries and vendorsAs technology advances, libraries are forced to reach beyond their own resources to find effective ways to maintain accuracy and superior service levels. Vendors provide databases and integrated library systems that perform those functions for profit. Library/Vendor Relationships examines the increasing cooperation in which libraries find they must participate in, and vice versa, with the vendors that provide system infrastructure and software. Expert contributors provide insights from all sides of this unique collaboration, offering

  5. Therapeutic interaction with an older personality disordered patient. (United States)

    Josephs, Lawrence; Sanders, Avihay; Gorman, Bernard S


    This study reflects an assessment of the relationship between change in defensive functioning and change in the therapeutic interaction during an eight-year treatment episode of an older personality disordered woman. The patient, Ms. Q, possessed schizoid, avoidant, and depressive personality disorders as well as major depression as assessed by the Millon Clinical Multiaxial Inventory-III (MCMI-III). At the end of the treatment episode, Ms. Q still possessed an avoidant personality disorder and significant depressive personality traits but no longer possessed clinically significant schizoid traits or major depression. Ms. Q made significant positive change in her adaptive defensive functioning as assessed by the Defense Mechanism Rating Scale (DMRS). Through time-series analysis it was discovered that positive change in adaptive defenses was predicted by increases in a specific type of therapeutic interaction as assessed by the Psychotherapy Q Sort (PQS). In this therapeutic interaction the therapist in a didactic and advice-giving manner highlighted the patient's role in a problem in a clear and coherent way that could be perceived as tactless. Time-series analysis revealed a reciprocal relationship in which positive changes in adaptive defenses predicted further increases in that particular quality of therapeutic interaction.

  6. Nucleic acid aptamers: research tools in disease diagnostics and therapeutics. (United States)

    Santosh, Baby; Yadava, Pramod K


    Aptamers are short sequences of nucleic acid (DNA or RNA) or peptide molecules which adopt a conformation and bind cognate ligands with high affinity and specificity in a manner akin to antibody-antigen interactions. It has been globally acknowledged that aptamers promise a plethora of diagnostic and therapeutic applications. Although use of nucleic acid aptamers as targeted therapeutics or mediators of targeted drug delivery is a relatively new avenue of research, one aptamer-based drug "Macugen" is FDA approved and a series of aptamer-based drugs are in clinical pipelines. The present review discusses the aspects of design, unique properties, applications, and development of different aptamers to aid in cancer diagnosis, prevention, and/or treatment under defined conditions.

  7. Microbubbles and Ultrasound: Therapeutic Applications in Diabetic Nephropathy. (United States)

    Cao, Wei J; Matkar, Pratiek N; Chen, Hao H; Mofid, Azadeh; Leong-Poi, Howard


    Diabetic nephropathy (DN) remains one of the most common causes of end-stage renal disease. Current therapeutic strategies aiming at optimization of serum glucose and blood pressure are beneficial in early stage DN, but are unable to fully prevent disease progression. With the limitations of current medical therapies and the shortage of available donor organs for kidney transplantation, the need for novel therapies to address DN complications and prevent progression towards end-stage renal failure is crucial. The development of ultrasound technology for non-invasive and targeted in-vivo gene delivery using high power ultrasound and carrier microbubbles offers great therapeutic potential for the prevention and treatment of DN. The promising results from preclinical studies of ultrasound-mediated gene delivery (UMGD) in several DN animal models suggest that UMGD offers a unique, non-invasive platform for gene- and cell-based therapies targeted against DN with strong clinical translation potential.

  8. Bioactive compounds of sea cucumbers and their therapeutic effects (United States)

    Shi, Shujuan; Feng, Wenjing; Hu, Song; Liang, Shixiu; An, Nina; Mao, Yongjun


    Sea cucumbers belong to the Class Holothuroidea of marine invertebrates. They are commercially valuable and prized as a food and folk medicine in Asia. Nutritionally, sea cucumbers have an impressive profile of valuable nutrients such as vitamins, minerals and amino acids. A number of unique biological and pharmacological activities/properties, including anticancer, anticoagulant/antithrombotic, antimicrobial, antioxidant, antihyperlipidemic, antihyperglycemic, anti-inflammatory, antihypertension and radioprotective, have been ascribed to various compounds isolated from sea cucumbers. The therapeutic properties and medicinal benefits of sea cucumbers can be linked to the presence of a wide array of bioactives, especially triterpene glycosides, acid mucopolysaccharide, sphingoid bases, glycolipids, fucosylated chondroitin sulfate, polysaccharides, phospholipids, cerebrosides, phosphatidylcholines, and other extracts and hydrolysates. This review highlights the valuable bioactive components as well as the multiple therapeutic properties of sea cucumbers with a view to exploring their potential uses as functional foods and a natural source of new multifunctional drugs.

    Cancer metabolism has emerged as an important area of research in recent years. Elucidation of the metabolic differences between cancer and normal cells and the underlying mechanisms will not only advance our understanding of fundamental cancer cell biology but also provide an important basis for the development of new therapeutic strategies and novel compounds to selectively eliminate cancer cells by targeting their unique metabolism. This article reviews several important metabolic alterations in cancer cells, with an emphasis on increased aerobic glycolysis (the Warburg effect) and glutamine addiction, and discusses the mechanisms that may contribute to such metabolic changes. In addition, metabolic alterations in cancer stem cells, mitochondrial metabolism and its influence on drug sensitivity, and potential therapeutic strategies and agents that target cancer metabolism are also discussed.

  10. Archaeal lipids in oral delivery of therapeutic peptides

    DEFF Research Database (Denmark)

    Jacobsen, Ann-Christin; Jensen, Sara M; Fricker, Gert;


    tetraether lipids. The inherent chemical stability and unique membrane-spanning characteristics of tetraether lipids render them interesting for oral drug delivery purposes. Archaeal lipids form liposomes spontaneously (archaeosomes) and may be incorporated in conventional liposomes (mixed vesicles). Both...... types of liposomes are promising to protect their drug cargo, such as therapeutic peptides, against the acidic environment of the stomach and proteolytic degradation in the intestine. They appear to withstand lipolytic enzymes and bile salts and may thus deliver orally administered therapeutic peptides...... to distant sections of the intestine or to the colon, where they may be absorbed, eventually by the help of absorption enhancers. Archaeal lipids and their semisynthetic derivatives may thus serve as biological source for the next generation oral drug delivery systems. The aim of this review is to present...

  11. Bombarding Cancer: Biolistic Delivery of therapeutics using Porous Si Carriers (United States)

    Zilony, Neta; Tzur-Balter, Adi; Segal, Ester; Shefi, Orit


    A new paradigm for an effective delivery of therapeutics into cancer cells is presented. Degradable porous silicon carriers, which are tailored to carry and release a model anti-cancer drug, are biolistically bombarded into in-vitro cancerous targets. We demonstrate the ability to launch these highly porous microparticles by a pneumatic capillary gene gun, which is conventionally used to deliver cargos by heavy metal carriers. By optimizing the gun parameters e.g., the accelerating gas pressure, we have successfully delivered the porous carriers, to reach deep targets and to cross a skin barrier in a highly spatial resolution. Our study reveals significant cytotoxicity towards the target human breast carcinoma cells following the delivery of drug-loaded carriers, while administrating empty particles results in no effect on cell viability. The unique combination of biolistics with the temporal control of payload release from porous carriers presents a powerful and non-conventional platform for designing new therapeutic strategies.

  12. Relational vulnerabilities of incarcerated and reentry mothers: therapeutic implications. (United States)

    Few-Demo, April L; Arditti, Joyce A


    A qualitative study involving a follow-up interview with 10 incarcerated and reentry mothers in rural southwest and central Virginia was conducted to explore the influence that women's close relationships have on their reentry experiences with their families. The Vulnerability Conceptual Model (VCM) was used to sensitize an examination of how incarcerated and reentry mothers negotiate relational vulnerabilities in the context of varying situational vulnerability. Grounded theory analysis revealed three themes that characterized relational vulnerabilities. Given our focus on close relationships and the potential of the VCM to identify opportunities for resilience and vulnerability, we highlighted the influence of ambiguous and ambivalent relationships and unresolved loss and grief due to relationship dissolution or the death of a parent, sibling, child, or intimate partner in the reentry process. The data revealed two types of reentry mothers with divergent trajectories for social reintegration. Implications of these types for therapeutic treatment approaches for reentry women are discussed. © The Author(s) 2013.

  13. Creativity and improvisation as therapeutic tools within music therapy. (United States)

    Tomaino, Concetta M


    The neuroscience of creativity and music improvisation is a fascinating topic and one with strong implications for clinical music therapy. Music therapists are trained to use musical improvisation as a means to bring their clients into deeper therapeutic relationship as well as free up any inhibitions or limitations that may block recovery. Could recent fMRI studies of jazz musicians showing areas of brain activation during music improvisation provide a new framework to understand underlying mechanisms at work with neurologically impaired individuals?

    Palchykov, Vasyl; Kertész, János; Barabási, Albert-László; Dunbar, Robin I M


    Social networks have turned out to be of fundamental importance both for our understanding human sociality and for the design of digital communication technology. However, social networks are themselves based on dyadic relationships and we have little understanding of the dynamics of close relationships and how these change over time. Evolutionary theory suggests that, even in monogamous mating systems, the pattern of investment in close relationships should vary across the lifespan when post-weaning investment plays an important role in maximising fitness. Mobile phone data sets provide us with a unique window into the structure of relationships and the way these change across the lifespan. We here use data from a large national mobile phone dataset to demonstrate striking sex differences in the pattern in the gender-bias of preferred relationships that reflect the way the reproductive investment strategies of the two sexes change across the lifespan: these differences mainly reflect women's shifting pattern...

  15. The third therapeutic system: faith healing strategies in the context of a generalized AIDS epidemic. (United States)

    Manglos, Nicolette D; Trinitapoli, Jenny


    Faith healing in sub-Saharan Africa has primarily been studied qualitatively among Pentecostal-Charismatic groups, and considered as its own phenomenon with little attention to its relationship to other modes of healing. Using data from Malawi, a religiously diverse African country with high HIV prevalence, we find that faith healing is pervasive across multiple religious traditions. For individuals, attending a faith healing congregation is associated with lower levels of generalized worry about AIDS, and this association is driven by those who switched churches before AIDS became widespread in rural areas. Use of condoms and traditional medicine are, on the other hand, positively associated with worry about AIDS. We argue that faith healing can be understood as a third therapeutic system that coexists with the well-documented biomedical and traditional systems. The success of faith healing approaches lies in their unique ability to combine individual-pragmatic and communal-ritualized aspects of healing to inform interpretations of the AIDS epidemic and its consequences.

  17. Uniqueness of rate-dependency, creep and stress relaxation behaviors for soft clays

    Institute of Scientific and Technical Information of China (English)

    朱启银; 尹振宇; 徐长节; 殷建华; 夏小和


    This work focuses on the uniqueness of rate-dependency, creep and stress relaxation behaviors for soft clays under one-dimensional condition. An elasto-viscoplastic model is briefly introduced based on the rate-dependency of preconsolidation pressure. By comparing the rate-dependency formulation with the creep based formulation, the relationship between rate-dependency and creep behaviors is firstly described. The rate-dependency based formulation is then extended to derive an analytical solution for the stress relaxation behavior with defining a stress relaxation coefficient. Based on this, the relationship between the rate-dependency coefficient and the stress relaxation coefficient is derived. Therefore, the uniqueness between behaviors of rate-dependency, creep and stress relaxation with their key parameters is obtained. The uniqueness is finally validated by comparing the simulated rate-dependency of preconsolidation pressure, the estimated values of secondary compression coefficient and simulations of stress relaxation tests with test results on both reconstituted Illite and Berthierville clay.

  18. Therapeutic approaches for celiac disease (United States)

    Plugis, Nicholas M.; Khosla, Chaitan


    Celiac disease is a common, lifelong autoimmune disorder for which dietary control is the only accepted form of therapy. A strict gluten-free diet is burdensome to patients and can be limited in efficacy, indicating there is an unmet need for novel therapeutic approaches to supplement or supplant dietary therapy. Many molecular events required for disease pathogenesis have been recently characterized and inspire most current and emerging drug-discovery efforts. Genome-wide association studies (GWAS) confirm the importance of human leukocyte antigen genes in our pathogenic model and identify a number of new risk loci in this complex disease. Here, we review the status of both emerging and potential therapeutic strategies in the context of disease pathophysiology. We conclude with a discussion of how genes identified during GWAS and follow-up studies that enhance susceptibility may offer insight into developing novel therapies. PMID:26060114

  4. Potential Therapeutic Effects of Psilocybin. (United States)

    Johnson, Matthew W; Griffiths, Roland R


    Psilocybin and other 5-hydroxytryptamine2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research. Here, we review therapeutic research on psilocybin, the classic psychedelic that has been the focus of most recent research. For mood and anxiety disorders, three controlled trials have suggested that psilocybin may decrease symptoms of depression and anxiety in the context of cancer-related psychiatric distress for at least 6 months following a single acute administration. A small, open-label study in patients with treatment-resistant depression showed reductions in depression and anxiety symptoms 3 months after two acute doses. For addiction, small, open-label pilot studies have shown promising success rates for both tobacco and alcohol addiction. Safety data from these various trials, which involve careful screening, preparation, monitoring, and follow-up, indicate the absence of severe drug-related adverse reactions. Modest drug-related adverse effects at the time of medication administration are readily managed. US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms.

  6. Therapeutic targeting of replicative immortality


    Yaswen, Paul; MacKenzie, Karen L.; Keith, W. Nicol; Hentosh, Patricia; Rodier, Francis; Zhu, Jiyue; Firestone, Gary L.; Matheu, Ander; Carnero, Amancio; Bilsland, Alan; Sundin, Tabetha; Honoki, Kanya; Fujii, Hiromasa; Georgakilas, Alexandros G.; Amedei, Amedeo


    One of the hallmarks of malignant cell populations is the ability to undergo continuous proliferation. This property allows clonal lineages to acquire sequential aberrations that can fuel increasingly autonomous growth, invasiveness, and therapeutic resistance. Innate cellular mechanisms have evolved to regulate replicative potential as a hedge against malignant progression. When activated in the absence of normal terminal differentiation cues, these mechanisms can result in a state of persis...

  7. Therapeutic perspectives in atopic dermatitis. (United States)

    Misery, Laurent


    Therapy of atopic dermatitis should comprise emollients, topical glucocorticosteroids, or calcineurin inhibitors, phototherapies, immunosuppressants like cyclosporin A, and other treatments. All these treatments should be improved, thanks to research. But new therapeutic perspectives should be given by topical anti-inflammatory substances, selective glucocorticoid receptor agonists, probiotics, interferon γ, TNFα inhibitors, inhibition of T cells or B cells, inhibition of IgE binding, and many other possibilities.

  13. Conotoxins that confer therapeutic possibilities

    KAUST Repository

    Essack, Magbubah


    Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey. These peptides target a wide variety of voltage- and ligand-gated ion channels, which make them an invaluable resource for studying the properties of these ion channels in normal and diseased states, as well as being a collection of compounds of potential pharmacological use in their own right. Examples include the United States Food and Drug Administration (FDA) approved pharmaceutical drug, Ziconotide (Prialt; Elan Pharmaceuticals, Inc.) that is the synthetic equivalent of the naturally occurring ?-conotoxin MVIIA, whilst several other conotoxins are currently being used as standard research tools and screened as potential therapeutic drugs in pre-clinical or clinical trials. These developments highlight the importance of driving conotoxin-related research. A PubMed query from 1 January 2007 to 31 August 2011 combined with hand-curation of the retrieved articles allowed for the collation of 98 recently identified conotoxins with therapeutic potential which are selectively discussed in this review. Protein sequence similarity analysis tentatively assigned uncharacterized conotoxins to predicted functional classes. Furthermore, conotoxin therapeutic potential for neurodegenerative disorders (NDD) was also inferred. 2012 by the authors; licensee MDPI.

  14. Avian Diagnostic and Therapeutic Antibodies

    Energy Technology Data Exchange (ETDEWEB)

    Bradley, David Sherman [UND SMHS


    A number of infectious agents have the potential of causing significant clinical symptomology and even death, but dispite this, the number of incidence remain below the level that supports producing a vaccine. Therapeutic antibodies provide a viable treatment option for many of these diseases. We proposed that antibodies derived from West Nile Virus (WNV) immunized geese would be able to treat WNV infection in mammals and potential humans. We demonstrated that WNV specific goose antibodies are indeed successful in treating WNV infection both prophylactically and therapeutically in a golden hamster model. We demonstrated that the goose derived antibodies are non-reactogenic, i.e. do not cause an inflammatory response with multiple exposures in mammals. We also developed both a specific pathogen free facility to house the geese during the antibody production phase and a patent-pending purification process to purify the antibodies to greater than 99% purity. Therefore, the success of these study will allow a cost effective rapidly producible therapeutic toward clinical testing with the necessary infrastructure and processes developed and in place.

  15. Therapeutic apheresis in autoimmune diseases (United States)

    Bambauer, Rolf; Latza, Reinhard; Bambauer, Carolin; Burgard, Daniel; Schiel, Ralf


    Systemic autoimmune diseases based on an immune pathogenesis produce autoantibodies and circulating immune complexes, which cause inflammation in the tissues of various organs. In most cases, these diseases have a bad prognosis without treatment. Therapeutic apheresis in combination with immunosuppressive therapies has led to a steady increase in survival rates over the last 35 years. Here we provide an overview of the most important pathogenic aspects indicating that therapeutic apheresis can be a supportive therapy in some systemic autoimmune diseases, such as systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, and inflammatory eye disease. With the introduction of novel and effective biologic agents, therapeutic apheresis is indicated only in severe cases, such as in rapid progression despite immunosuppressive therapy and/or biologic agents, and in patients with renal involvement, acute generalized vasculitis, thrombocytopenia, leucopenia, pulmonary, cardiac, or cerebral involvement. In mild forms of autoimmune disease, treatment with immunosuppressive therapies and/or biologic agents seems to be sufficient. The prognosis of autoimmune diseases with varying organ manifestations has improved considerably in recent years, due in part to very aggressive therapy schemes.

  16. Diagnostic and therapeutic peroral cholangioscopy

    Directory of Open Access Journals (Sweden)

    Jong Ho Moon


    Full Text Available Peroral cholangioscopy (POC provides direct visualization of the bile duct and facilitates diagnostic or therapeutic intervention. The currently available single-operator POC systems are "Mother-baby" scope system, SpyGlass direct visualization system, and direct POC using a regular ultra-slim upper endoscope. Direct POC using an ultra-slim upper endoscope having a larger 2-mm working channel can provide a valuable and economic solution for evaluating bile-duct lesions. Main diagnostic procedures under direct POC are visual characterization and optically guided target biopsy for the indeterminate bile duct lesion. Image-enhanced endoscopy such as narrow-band imaging has shown promise for more detailed evaluation of mucosal abnormality and can be performed under direct POC. Intracorporeal lithotripsy such as electrohydraulic lithotripsy or laser lithotripsy is a main therapeutic intervention of direct POC for patients with bile duct stones that are resistant to conventional endoscopic stone-removal procedures. Besides, tumor ablation therapy, such as photodynamic therapy and argon plasma coagulation may be also performed using direct POC. Further developments of the endoscope and specialized accessories or devices are expected to facilitate diagnostic and therapeutic role of this cholangioscopic procedure.

  17. DNA as therapeutics; an update

    Directory of Open Access Journals (Sweden)

    Saraswat P


    Full Text Available Human gene therapy is the introduction of new genetic material into the cells of an individual with the intention of producing a therapeutic benefit for the patient. Deoxyribonucleic acid and ribonucleic acid are used in gene therapy. Over time and with proper oversight, human gene therapy might become an effective weapon in modern medicine′s arsenal to help fight diseases such as cancer, acquired immunodeficiency syndrome, diabetes, high blood pressure, coronary heart disease, peripheral vascular disease, neurodegenerative diseases, cystic fibrosis, hemophilia and other genetic disorders. Gene therapy trials in humans are of two types, somatic and germ line gene therapy. There are many ethical, social, and commercial issues raised by the prospects of treating patients whose consent is impossible to obtain. This review summarizes deoxyribonucleic acid-based therapeutics and gene transfer technologies for the diseases that are known to be genetic in origin. Deoxyribonucleic acid-based therapeutics includes plasmids, oligonucleotides for antisense and antigene applications, deoxyribonucleic acid aptamers and deoxyribonucleic acidzymes. This review also includes current status of gene therapy and recent developments in gene therapy research.

  18. Copper complexes as therapeutic agents. (United States)

    Duncan, Clare; White, Anthony R


    The importance of transition metals in biological processes has been well established. Copper (Cu) is a transition metal that can exist in oxidised and reduced states. This allows it to participate in redox and catalytic chemistry, making it a suitable cofactor for a diverse range of enzymes and molecules. Cu deficiency or toxicity is implicated in a variety of pathological conditions; therefore inorganic complexes of Cu have been investigated for their therapeutic and diagnostic potential. These Cu complexes have been shown to be effective in cancer treatment due to their cytotoxic action on tumour cells. Alternatively, Cu complexes can also modulate Cu homeostasis in the brain, resulting in protective effects in several models of neurodegeneration. In other diseases such as coronary heart disease and skin disease, the success of Cu complexes as potential therapeutics will most likely be due to their ability to increase SOD activity, leading to relief of oxidative stress. This review seeks to provide a broad insight into some of the diverse actions of Cu complexes and demonstrate the strong future for these compounds as potential therapeutic agents.

  19. Therapeutic Tools in Pancreatic Cancer

    Directory of Open Access Journals (Sweden)

    Christopher J Hoimes


    Full Text Available Pancreatic cancer is the fourth leading cause of cancer death in the United States and has a lower survival rate than other digestive tract tumors. It remains a therapeutic challenge with limited active agents. Honing our current understanding of markers of toxicity and response, and individualizing treatment with the prognostic and therapeutic tools available are important to make a worthy impact on a patient’s course. The authors summarize selected abstracts from the ASCO Gastrointestinal Cancers Symposium, San Francisco, CA, USA, January 15-17, 2009. The Symposium featured pancreatic cancer in 84 research abstracts, of which, seven are reviewed that focus on markers of toxicity: cytidine deaminase (Abstract #151 and haptogloin (Abstract #167 as markers of gemcitabine toxicity; markers of response: use of PET scan for prognosis (Abstract #157, and correlations with CA 19-9 to postchemo-radiation resectability (Abstract #215 and time to progression (Abstract #160; and individualized applications: characterizing the phenotypic similarities between a patient tumor and the direct xenograft (Abstract #154 and a report about the poor outcome of patients with ascites (Abstract #220. Validated clinical tools that can assist in managing patients through the narrow therapeutic window are needed.

    Full Text Available Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey. These peptides target a wide variety of voltage- and ligand-gated ion channels, which make them an invaluable resource for studying the properties of these ion channels in normal and diseased states, as well as being a collection of compounds of potential pharmacological use in their own right. Examples include the United States Food and Drug Administration (FDA approved pharmaceutical drug, Ziconotide (Prialt®; Elan Pharmaceuticals, Inc. that is the synthetic equivalent of the naturally occurring ω-conotoxin MVIIA, whilst several other conotoxins are currently being used as standard research tools and screened as potential therapeutic drugs in pre-clinical or clinical trials. These developments highlight the importance of driving conotoxin-related research. A PubMed query from 1 January 2007 to 31 August 2011 combined with hand-curation of the retrieved articles allowed for the collation of 98 recently identified conotoxins with therapeutic potential which are selectively discussed in this review. Protein sequence similarity analysis tentatively assigned uncharacterized conotoxins to predicted functional classes. Furthermore, conotoxin therapeutic potential for neurodegenerative disorders (NDD was also inferred.

  1. DNA as therapeutics; an update. (United States)

    Saraswat, P; Soni, R R; Bhandari, A; Nagori, B P


    Human gene therapy is the introduction of new genetic material into the cells of an individual with the intention of producing a therapeutic benefit for the patient. Deoxyribonucleic acid and ribonucleic acid are used in gene therapy. Over time and with proper oversight, human gene therapy might become an effective weapon in modern medicine's arsenal to help fight diseases such as cancer, acquired immunodeficiency syndrome, diabetes, high blood pressure, coronary heart disease, peripheral vascular disease, neurodegenerative diseases, cystic fibrosis, hemophilia and other genetic disorders. Gene therapy trials in humans are of two types, somatic and germ line gene therapy. There are many ethical, social, and commercial issues raised by the prospects of treating patients whose consent is impossible to obtain. This review summarizes deoxyribonucleic acid-based therapeutics and gene transfer technologies for the diseases that are known to be genetic in origin. Deoxyribonucleic acid-based therapeutics includes plasmids, oligonucleotides for antisense and antigene applications, deoxyribonucleic acid aptamers and deoxyribonucleic acidzymes. This review also includes current status of gene therapy and recent developments in gene therapy research.

  2. Enzyme therapeutics for systemic detoxification. (United States)

    Liu, Yang; Li, Jie; Lu, Yunfeng


    Life relies on numerous biochemical processes working synergistically and correctly. Certain substances disrupt these processes, inducing living organism into an abnormal state termed intoxication. Managing intoxication usually requires interventions, which is referred as detoxification. Decades of development on detoxification reveals the potential of enzymes as ideal therapeutics and antidotes, because their high substrate specificity and catalytic efficiency are essential for clearing intoxicating substances without adverse effects. However, intrinsic shortcomings of enzymes including low stability and high immunogenicity are major hurdles, which could be overcome by delivering enzymes with specially designed nanocarriers. Extensive investigations on protein delivery indicate three types of enzyme-nanocarrier architectures that show more promise than others for systemic detoxification, including liposome-wrapped enzymes, polymer-enzyme conjugates, and polymer-encapsulated enzymes. This review highlights recent advances in these nano-architectures and discusses their applications in systemic detoxifications. Therapeutic potential of various enzymes as well as associated challenges in achieving effective delivery of therapeutic enzymes will also be discussed.

  3. The importance of relationships in mental health care: A qualitative study of service users' experiences of psychiatric hospital admission in the UK

    Slade Mike


    Full Text Available Abstract Background While a number of studies have looked at life on service users' experiences of life on psychiatric wards, no research exists that have approached these experiences from the user perspective since the introduction of community care. Methods This user-led study uses a participatory approach to develop an understanding of the processes and themes which define the user experience of hospitalisation. Nineteen service users who had all had inpatient stays in psychiatric hospitals in London were interviewed in the community. Results Relationships formed the core of service users' experiences. Three further codes, treatment, freedom and environment defined the role of hospital and its physical aspects. Themes of communication, safety, trust, coercion, and cultural competency contributed to the concept of relationships. Conclusion Relationships with an individual which comprised effective communication, cultural sensitivity, and the absence of coercion resulted in that person being attributed with a sense of trust. This resulted in the patient experiencing the hospital as a place of safety in terms of risk from other patients and staff. Barriers to positive relationships included ineffective and negative communication, a lack of trust, a lack of safety in terms of staff as ineffective in preventing violence, and as perpetrators themselves, and the use of coercion by staff. This unique perspective both acts as a source of triangulation with previous studies and highlights the importance of the therapeutic relationship in providing a safe and therapeutic milieu for the treatment of people with acute mental health problems.

  4. Nonlinear independent component analysis: Existence and uniqueness results. (United States)

    Hyvärinen, Aapo; Pajunen, Petteri


    The question of existence and uniqueness of solutions for nonlinear independent component analysis is addressed. It is shown that if the space of mixing functions is not limited there exists always an infinity of solutions. In particular, it is shown how to construct parameterized families of solutions. The indeterminacies involved are not trivial, as in the linear case. Next, it is shown how to utilize some results of complex analysis to obtain uniqueness of solutions. We show that for two dimensions, the solution is unique up to a rotation, if the mixing function is constrained to be a conformal mapping together with some other assumptions. We also conjecture that the solution is strictly unique except in some degenerate cases, as the indeterminacy implied by the rotation is essentially similar to estimating the model of linear ICA.

    Full Text Available Embedding uniqueness in characteristics of song signal and accustoming changes of environment is one of the challenging issues for researchers with maintaining its audible quality. Researchers are modifying or manipulating audio signal properties for generating uniqueness in content such a manner that will not vary so much in changed environment or changes can be easily defined due to unique structure of song signal. In this paper, an approach has been made based on defining a symmetric structure of song signal, followed by some secret code embedding in a specified manner will not alter the trade off ratio of embedding/modifying data but provide uniqueness in properties, even retain the properties in changing environment/ format. Therefore, authentication of song signal is easily achieved with these self manipulated properties. A comparative study has been made with similar existing techniques and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav" stereo sound file.

  13. [Heterogeneity and homologies of the repeating and unique DNA of dragonflies (Odonata, Insecta)]. (United States)

    Petrov, N B; Aleshin, V V


    A relative content of unique and reiterated nucleotide sequences in DNA of eleven dragonfly species was estimated. The degree of intra- and intergenomic divergence of these DNA sequences was determined by means of DNA-DNA hybridization. Species from different genera share 40-45% of the repetitive sequences and those from different families--from 11 to 20% only. Data on the thermostability of homo- and heteroduplexes suggest that new families of the repetitive sequences have arisen repeatedly during dragonflies evolution. The quality of homologous unique sequences in the DNA compared (20-97%) correlates with the taxonomic relationships of species. Phylogenesis of some dragonfly families is discussed in view of the results obtained.

    Chenyang Fu; Kaida Xiao; Dimosthenis Karatzas; Sophie Wuerger


    Clromatic sensitivity along the protan, deutan, and tritan lines and the loci of the unique hues (red, green,yellow, blue) for a very large sample (n = 185) of colour-normal observers ranging from 18 to 75 years of age are assessed. Visual judgments are obtained under normal viewing conditions using colour patches on self-luminous display under controlled adaptation conditions. Trivector discrimination thresholds show an increase as a function of age along the protan, deutan, and tritan axes, with the largest increase present along the tritan line, less pronounced shifts in unique hue settings are also observed. Based on the chromatic (protan, deutan, tritan) thresholds and using scaled cone signals, we predict the unique hue changes with ageing. A dependency on age for unique red and unique yellow for predicted hue angle is found. We conclude that the chromatic sensitivity deteriorates significantly with age, whereas the appearance of unique hues is much less affected, remaining almost constant despite the known changes in the ocular media.%@@ Clromatic sensitivity along the protan, deutan, and tritan lines and the loci of the unique hues (red, green,yellow, blue) for a very large sample (n = 185) of colour-normal observers ranging from 18 to 75 years of age are assessed.Visual judgments are obtained under normal viewing conditions using colour patches on self-luminous display under controlled adaptation conditions.Trivector discrimination thresholds show an increase as a function of age along the protan, deutan, and tritan axes, with the largest increase present along the tritan line, less pronounced shifts in unique hue settings are also observed.

  16. Euler equation existence, non-uniqueness and mesh converged statistics. (United States)

    Glimm, James; Sharp, David H; Lim, Hyunkyung; Kaufman, Ryan; Hu, Wenlin


    We review existence and non-uniqueness results for the Euler equation of fluid flow. These results are placed in the context of physical models and their solutions. Non-uniqueness is in direct conflict with the purpose of practical simulations, so that a mitigating strategy, outlined here, is important. We illustrate these issues in an examination of mesh converged turbulent statistics, with comparison to laboratory experiments.

    JIANG; Long


    This paper establishes a limit theorem for solutions of backward stochastic differential equations (BSDEs). By this limit theorem, this paper proves that, under the standard assumption g(t,y,0)≡0, the generator g of a BSDE can be uniquely determined by the corresponding g-expectation εg; this paper also proves that if a filtration consistent expectation ε can be represented as a g-expectation εg, then the corresponding generator g must be unique.

  18. Generic uniqueness conditions for the canonical polyadic decomposition and INDSCAL

Then we consider the case when the tensor and all its rank-$1$ terms have symmetric frontal slices (INDSCAL). Our results complement the existing bounds for generic uniqueness of the CPD and relax the existing bounds for INDSCAL. The derivation makes use of algebraic geometry. We...

  19. Practical relevance of pattern uniqueness in forensic science. (United States)

    Jayaprakash, Paul T


    Uniqueness being unprovable, it has recently been argued that individualization in forensic science is irrelevant and, probability, as applied for DNA profiles, should be applied for all identifications. Critiques against uniqueness have omitted physical matching, a realistic and tangible individualization that supports uniqueness. Describing case examples illustrating pattern matches including physical matching, it is indicated that individualizations are practically relevant for forensic science as they establish facts on a definitive basis providing firm leads benefitting criminal investigation. As a tenet of forensic identification, uniqueness forms a fundamental paradigm relevant for individualization. Evidence on the indeterministic and stochastic causal pathways of characteristics in patterns available in the related fields of science sufficiently supports the proposition of uniqueness. Characteristics involved in physical matching and matching achieved in patterned evidence existing in the state of nature are not events amenable for counting; instead these are ensemble of visible units occupying the entire pattern area stretching the probability of re-occurrence of a verisimilitude pattern into infinity offering epistemic support to uniqueness. Observational methods are as respectable as instrumental or statistical methods since they are capable of generating results that are tangible and obviously valid as in physical matching. Applying the probabilistic interpretation used for DNA profiles to the other patterns would be unbefitting since these two are disparate, the causal pathways of the events, the loci, in the manipulated DNA profiles being determinable. While uniqueness enables individualizations, it does not vouch for eliminating errors. Instead of dismissing uniqueness and individualization, accepting errors as human or system failures and seeking remedial measures would benefit forensic science practice and criminal investigation.

  3. Biominetic High Density Lipoproteins for the Delivery of Therapeutic Oligonucleotides (United States)

    Tripathy, Sushant

    Advances in nanotechnology have brought about novel inorganic and hybrid nanoparticles with unique physico-chemical properties that make them suitable for a broad range of applications---from nano-circuitry to drug delivery. A significant part of those advancements have led to ground-breaking discoveries that have changed the approaches to formulation of therapeutics against diseases, such as cancer. Now-a-days the focus does not lie solely on finding a candidate small-molecule therapeutic with minimal adverse effects, but researchers are looking up to nanoparticles to improve biodistribution and biocompatibility profile of clinically proven therapeutics. The plethora of conjugation chemistries offered by currently extant inorganic nanoparticles have, in recent years, led to great leaps in the field of biomimicry---a modality that promises high biocompatibility. Further, in the pursuit of highly specific therapeutic molecules, researchers have turned to silencing oligonucleotides and some have already brought together the strengths of nanoparticles and silencing oligonucleotides in search of an efficacious therapy for cancer with minimal adverse effects. This dissertation work focuses on such a biomimetic platform---a gold nanoparticle based high density lipoprotein biomimetic (HDL NP), for the delivery of therapeutic oligonucleotides. The first chapter of this body of work introduces the molecular target of the silencing oligonucleotides---VEGFR2, and its role in the progression of solid tumor cancers. The background information also covers important aspects of natural high density lipoproteins (HDL), especially their innate capacity to bind and deliver exogenous and endogenous silencing oligonucleotides to tissues that express their high affinity receptor SRB1. We subsequently describe the synthesis of the biomimetic HDL NP and its oligonucleotide conjugates, and establish their biocompatibility. Further on, experimental data demonstrate the efficacy of silencing

  4. Programming supramolecular biohybrids as precision therapeutics. (United States)

    Ng, David Yuen Wah; Wu, Yuzhou; Kuan, Seah Ling; Weil, Tanja


    CONSPECTUS: Chemical programming of macromolecular structures to instill a set of defined chemical properties designed to behave in a sequential and precise manner is a characteristic vision for creating next generation nanomaterials. In this context, biopolymers such as proteins and nucleic acids provide an attractive platform for the integration of complex chemical design due to their sequence specificity and geometric definition, which allows accurate translation of chemical functionalities to biological activity. Coupled with the advent of amino acid specific modification techniques, "programmable" areas of a protein chain become exclusively available for any synthetic customization. We envision that chemically reprogrammed hybrid proteins will bridge the vital link to overcome the limitations of synthetic and biological materials, providing a unique strategy for tailoring precision therapeutics. In this Account, we present our work toward the chemical design of protein- derived hybrid polymers and their supramolecular responsiveness, while summarizing their impact and the advancement in biomedicine. Proteins, in their native form, represent the central framework of all biological processes and are an unrivaled class of macromolecular drugs with immense specificity. Nonetheless, the route of administration of protein therapeutics is often vastly different from Nature's biosynthesis. Therefore, it is imperative to chemically reprogram these biopolymers to direct their entry and activity toward the designated target. As a consequence of the innate structural regularity of proteins, we show that supramolecular interactions facilitated by stimulus responsive chemistry can be intricately designed as a powerful tool to customize their functions, stability, activity profiles, and transportation capabilities. From another perspective, a protein in its denatured, unfolded form serves as a monodispersed, biodegradable polymer scaffold decorated with functional side

  6. [Therapeutic update in cystic fibrosis]. (United States)

    Durupt, S; Nove Josserand, R; Durieu, I


    We present the recent therapeutic advances in the cystic fibrosis care. It concerns improvements in symptomatic treatment with the development of dry powder inhaled antibiotics that improved quality of life, and innovative treatments namely the modulators of the cystic fibrosis transmembrane protein conductance regulator (CFTR), molecules which act specifically at the level of the defective mechanisms implied in the disease. The life expectancy of cystic fibrosis patients born after 2000, is estimated now to be about 50 years. This improvement of survival was obtained with the organization of the care within the specialized centers for cystic fibrosis (Centre de ressource et de compétences de la mucoviscidose) and remains still based on heavy symptomatic treatments. Dry powder inhaled antibiotics constitute a significant time saving for patients to whom all the care can achieve two hours daily. Since 2012, the modulators of CFTR, molecules allowing a pharmacological approach targeted according to the type of the mutations, allows a more specific approach of the disease. Ivacaftor (Kalydeco(®)) which potentialises the function of the CFTR protein expressed on the cellular surface is now available for patients with the G551D mutation. Lumacaftor is going to be tested in association with ivacaftor in patients with the F508del mutation, that is present in at least 75% of the patients. The ataluren which allows the production of a functional protein CFTR in patients with a no sense mutation is the third representing of this new therapeutic class. We presently have numerous symptomatic treatments for the cystic fibrosis care. The development of CFTR modulators, today available to a restricted number of patients treated with ivacaftor represents a very promising therapeutic avenue. It will represent probably the first step to a personalized treatment according to CFTR genotype. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by

  8. Relationship authenticity partially mediates the effects of attachment on relationship satisfaction. (United States)

    Rasco, Danney; Warner, Rebecca M


    Individuals with anxious and avoidant attachment tend to experience less satisfaction in their relationships. Past research suggests the negative effects of attachment on relationship satisfaction may be partially mediated by self-disclosure and self-concealment; the present study evaluated relationship authenticity as a potential additional mediator. Confirmatory factor analysis indicated that relationship authenticity is distinct from self-disclosure and self-concealment. Relationship authenticity predicted additional variance in relationship satisfaction controlling for attachment, self-disclosure, and self-concealment. The results were consistent with relationship authenticity, along with self-disclosure and self-concealment, partially mediating the effects of attachment on relationship satisfaction. These findings suggest that relationship authenticity may play a unique role in understanding how attachment influences relationship satisfaction. Theoretical and clinical implications are discussed.

  11. Exploring breast with therapeutic ductoscopy. (United States)

    Balci, Fatih Levent; Feldman, Sheldon Marc


    Breast lesions are thought to arise mostly from the epithelium of ductal lining. Conventional imaging could only show indirect images of suspected lesions which are confirmed by percutaneous biopsies. However, ductoscopy provides direct images of the ductal epithelium which is the source of most malignant and papillary lesions. As an advance of current ductoscopy systems, pathologic nipple discharge (PND) could be treated ductoscopically by miniaturized endo-baskets or wires. Our goal is to discuss current intraductal technology which enables diagnostic and therapeutic advance for breast lesions that cause nipple discharge.

  12. The selective therapeutic apheresis procedures. (United States)

    Sanchez, Amber P; Cunard, Robyn; Ward, David M


    Selective apheresis procedures have been developed to target specific molecules, antibodies, or cellular elements in a variety of diseases. The advantage of the selective apheresis procedures over conventional therapeutic plasmapheresis is preservation of other essential plasma components such as albumin, immunoglobulins, and clotting factors. These procedures are more commonly employed in Europe and Japan, and few are available in the USA. Apheresis procedures discussed in this review include the various technologies available for low-density lipoprotein (LDL) apheresis, double filtration plasmapheresis (DFPP), cryofiltration, immunoadsorption procedures, adsorption resins that process plasma, extracorporeal photopheresis, and leukocyte apheresis.

Finally, the article posits that enactments have widened the scope of analysis and contributed to its vitality.

  14. Exploring apposite therapeutic target for apoptosis in filarial parasite: a plausible hypothesis. (United States)

    Hande, Sneha; Goswami, Kalyan; Jena, Lingaraj; Reddy, Maryada Venkata Rami


    Human lymphatic filariasis is a parasitic disease with profound socioeconomic encumbrance owing to its associated disability, affecting predominantly but not limited to the developing nations of tropics and subtropics. There are several technical issues like poor therapeutic and preventive repertoire as well as administrative and infrastructural limitations which jeopardize the salvage measures and further complicate the plight. Therefore, considering the gravity of the problem, WHO has mandated (under tropical disease research scheme) for placing emphasis on validation of novel therapeutic targets against this disease with the unfortunate tag of 'neglected tropical disease'. However, dearth of knowledge of parasite biology viciously coupled with difficulty of access to parasitic material from suitable animal model along with growing cost burden of high end research poses formidable challenge. Based on the recent research evidences, here we propose a premise with targeted apoptotic impact as a novel rationale to be exploited towards anti-parasitic drug development. The new era of bioinformatics ushers in new optimism with a wide range of genomic and proteomic database in public domain. Such platform might offer wonders for drug research, but needs highly selective criterion specificity. In order to test our hypothesis presumptively, we deployed a scheme for identification of target proteins from filarial parasitic origin through wide database search with precise criteria of non-homology against the host along with functional essentiality for the parasite. Further screening for proteins with growth potential from such list of essential non-homologous proteins was undertaken to mine out suitable representative target for ensuing apoptotic impact though effective inhibitors. A unique protein enzyme, RNA dependent RNA polymerase, which besides its vital role in RNA virus is believed to have regulatory role in gene expression, emerged as a plausible target. This protein

    The Unique Signal is a key constituent of Enhanced Nuclear Detonation Safety (ENDS). Although the Unique Signal approach is well prescribed and mathematically assured, there are numerous unsolved mathematical problems that could help assess the risk of deviations from the ideal approach. Some of the mathematics-based results shown in this report are: 1. The risk that two patterns with poor characteristics (easily generated by inadvertent processes) could be combined through exclusive-or mixing to generate an actual Unique Signal pattern has been investigated and found to be minimal (not significant when compared to the incompatibility metric of actual Unique Signal patterns used in nuclear weapons). 2. The risk of generating actual Unique Signal patterns with linear feedback shift registers is minimal, but the patterns in use are not as invulnerable to inadvertent generation by dependent processes as previously thought. 3. New methods of testing pair-wise incompatibility threats have resulted in no significant problems found for the set of Unique Signal patterns currently used. Any new patterns introduced would have to be carefully assessed for compatibility with existing patterns, since some new patterns under consideration were found to be deficient when associated with other patterns in use. 4. Markov models were shown to correspond to some of the engineered properties of Unique Signal sequences. This gives new support for the original design objectives. 5. Potential dependence among events (caused by a variety of communication protocols) has been studied. New evidence has been derived of the risk associated with combined communication of multiple events, and of the improvement in abnormal-environment safety that can be achieved through separate-event communication.

  16. Curcumolide, a unique sesquiterpenoid with anti-inflammatory properties from Curcuma wenyujin. (United States)

    Dong, Jianyong; Shao, Weiwei; Yan, Pengcheng; Cai, Xiaoqing; Fang, Lianglian; Zhao, Xiaowei; Lin, Weiwei; Cai, Yuan


    Curcumolide, a novel sesquiterpenoid with a unique 5/6/5 tricyclic skeleton, was isolated from Curcuma wenyujin. The structure and absolute configuration were elucidated by extensive NMR, ECD data analysis, and a single-crystal X-ray study. This molecule exhibited significant anti-inflammatory effects in LPS-induced RAW 264.7 macrophages. It suppressed LPS-induced NF-κB activation, including the nuclear translocation and DNA binding activity of NF-κB, and decreased tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), nitric oxide (NO) and reactive oxygen species (ROS) production. Therefore, Curcumolide may have therapeutic potential for treating inflammatory diseases by inhibiting NF-κB activation and pro-inflammatory mediator production. Copyright © 2014 Elsevier Ltd.

  17. Rapid resolution of grief with IV infusion of ketamine: a unique phenomenological experience

    Directory of Open Access Journals (Sweden)

    Mahesh Ramanna Gowda


    Full Text Available Ketamine, a primarily FDA-approved anaesthetic agent is also used as recreational drug. Based on preclinical findings and later the clinical observations it is noted to have rapid antidepressant effect due to its mechanisms related to NMDA antagonism. In spite of established evidence of ketamine being effective in depression with significant role in treatment resistant cases as well, there was absolute dearth of literature regarding its utility in grief-related disorders. In this context we present a case of 28-year-old graduate male who presented to us in complicated grief following death of his wife due to obstetric complications. With the patient and immediate family members consenting for use of ketamine as off-label use, patient had single IV infusion of ketamine following which he had unique phenomenological experience ultimately resolving his grief in few minutes. Through this case we highlight the enormous therapeutic promise of ketamine in complicated grief.

  18. Crossing the Vascular Wall: Common and Unique Mechanisms Exploited by Different Leukocyte Subsets during Extravasation

    Directory of Open Access Journals (Sweden)

    Michael Schnoor


    Full Text Available Leukocyte extravasation is one of the essential and first steps during the initiation of inflammation. Therefore, a better understanding of the key molecules that regulate this process may help to develop novel therapeutics for treatment of inflammation-based diseases such as atherosclerosis or rheumatoid arthritis. The endothelial adhesion molecules ICAM-1 and VCAM-1 are known as the central mediators of leukocyte adhesion to and transmigration across the endothelium. Engagement of these molecules by their leukocyte integrin receptors initiates the activation of several signaling pathways within both leukocytes and endothelium. Several of such events have been described to occur during transendothelial migration of all leukocyte subsets, whereas other mechanisms are known only for a single leukocyte subset. Here, we summarize current knowledge on regulatory mechanisms of leukocyte extravasation from a leukocyte and endothelial point of view, respectively. Specifically, we will focus on highlighting common and unique mechanisms that specific leukocyte subsets exploit to succeed in crossing endothelial monolayers.

  19. Congenital nasal pyriform aperture stenosis in association with solitary median maxillary central incisor: unique radiologic features. (United States)

    Yang, Sara; Orta, Pedro; Renk, Elizabeth M; Inman, Jared C


    Solitary median maxillary central incisor (SMMCI) coexists in 34%-65% of patients initially diagnosed with congenital nasal pyriform aperture stenosis. SMMCI, a genetic syndrome, warrants consideration for further screening because of its high prevalence of other diagnostic possibilities-specifically central defects, like nasal obstruction and hypothalamo-pituitary axis abnormalities. We report on a presentation of SMMCI with congenital nasal pyriform aperture stenosis which highlights the unique radiologic features and notes the relationship between these two central associated findings in the literature.

  20. Novel therapeutics in multiple sclerosis management: clinical applications. (United States)

    Leist, Thomas; Hunter, Samuel F; Kantor, Daniel; Markowitz, Clyde


    Multiple sclerosis (MS) affects an estimated 300,000 individuals in the United States. No cure exists and although there is a lack of consensus on management, strategies to modify disease course are available. These strategies involve initiating disease-modifying therapies that have been found to slow disease progression and prevent disability symptoms, thereby improving function for MS patients. The overall goal of early disease management is to intervene prior to irreversible neuronal destruction in order to delay disability progression and improve quality of life. Maintaining a lower level of disability for a longer period of time postpones and ultimately attempts to prevent reaching a level of immobility and irreversible disability. However, due to the complex nature of disease and its unique, individual patient course, no patient can be treated alike and no patient responds to therapy similarly. Therefore, MS research is continuous in its evolution of therapeutic development, focusing on neuroprotective effects and agents with distinctive mechanisms of action allowing for unique safety and efficacy profiles. Investigations include novel oral agents and monoclonal antibodies. Many of the approved agents also are continually being investigated in order to evaluate comparative data, the most appropriate means of implementing subsequent therapy upon failure, responsiveness to therapeutic agent when switched, and long-term safety and efficacy. This multimedia webcast educational activity will cover the current state of MS science, current therapies in MS, emerging treatments in clinical trials for MS as well as differences between physicians in diagnosis and management of MS and their evolving practices.

  2. [Therapeutic Aggressiveness and Liquid Oncology]. (United States)

    Barón Duarte, F J; Rodríguez Calvo, M S; Amor Pan, J R


    Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend. About 25% of patients fulfill at least one criterion of aggressiveness. This result could be explained by a liquid Oncology which does not prioritize the patient as a moral subject in the clinical appointment. Medical care is oriented to necessities and must be articulated in a model focused on dignity and communication. Its implementation through Advanced Care Planning, consideration of patient's values and preferences, and Limitation of therapeutic effort are ways to reduce aggressiveness and improve clinical practice at the end of life. We need to encourage synergic and proactive attitudes, adding the best of cancer research with the best clinical care for the benefit of human being, moral subject and main goal of Medicine.

  3. Neuroinflammation: a potential therapeutic target. (United States)

    Craft, Jeffrey M; Watterson, D Martin; Van Eldik, Linda J


    The increased appreciation of the importance of glial cell-propagated inflammation (termed 'neuroinflammation') in the progression of pathophysiology for diverse neurodegenerative diseases, has heightened interest in the rapid discovery of neuroinflammation-targeted therapeutics. Efforts include searches among existing drugs approved for other uses, as well as development of novel synthetic compounds that selectively downregulate neuroinflammatory responses. The use of existing drugs to target neuroinflammation has largely met with failure due to lack of efficacy or untoward side effects. However, the de novo development of new classes of therapeutics based on targeting selective aspects of glia activation pathways and glia-mediated pathophysiologies, versus targeting pathways of quantitative importance in non-CNS inflammatory responses, is yielding promising results in preclinical animal models. The authors briefly review selected clinical and preclinical data that reflect the prevailing approaches targeting neuroinflammation as a pathophysiological process contributing to onset or progression of neurodegenerative diseases. The authors conclude with opinions based on recent experimental proofs of concept using preclinical animal models of pathophysiology. The focus is on Alzheimer's disease, but the concepts are transferrable to other neurodegenerative disorders with an inflammatory component.

  4. Shiga Toxin Therapeutics: Beyond Neutralization

    Directory of Open Access Journals (Sweden)

    Gregory Hall


    Full Text Available Ribotoxic Shiga toxins are the primary cause of hemolytic uremic syndrome (HUS in patients infected with Shiga toxin-producing enterohemorrhagic Escherichia coli (STEC, a pathogen class responsible for epidemic outbreaks of gastrointestinal disease around the globe. HUS is a leading cause of pediatric renal failure in otherwise healthy children, resulting in a mortality rate of 10% and a chronic morbidity rate near 25%. There are currently no available therapeutics to prevent or treat HUS in STEC patients despite decades of work elucidating the mechanisms of Shiga toxicity in sensitive cells. The preclinical development of toxin-targeted HUS therapies has been hindered by the sporadic, geographically dispersed nature of STEC outbreaks with HUS cases and the limited financial incentive for the commercial development of therapies for an acute disease with an inconsistent patient population. The following review considers potential therapeutic targeting of the downstream cellular impacts of Shiga toxicity, which include the unfolded protein response (UPR and the ribotoxic stress response (RSR. Outcomes of the UPR and RSR are relevant to other diseases with large global incidence and prevalence rates, thus reducing barriers to the development of commercial drugs that could improve STEC and HUS patient outcomes.

  6. [Vasculitis - diagnostic and therapeutic advances]. (United States)

    De Albuquerque, R; Machado, Filipa


    Vasculitis is characterized by inflammation and necrosis of blood vessels walls. It represents a heterogeneous group of conditions, whose etiopathogenic mechanisms remain unclear. Although uncommon, with an annual incidence of 40-54 cases per 1.000.000 persons, this is an important cause of multiorganic dysfunction and premature mortality. Depending on the affected vessels, it can cause diverse clinical presentations, which makes difficult its recognition. It is therefore a challenge for any clinician. This paper reviews the diagnostic and therapeutic advances of the most common forms of vasculitis, in order to optimize the approach and management of this clinical entity. We have conducted a search in Medline database on articles written in English, published for the last 10 years using the keywords: vasculitis, epidemiology, classification, diagnosis and treatment. To minimize the impact of vasculitis it is essential an early diagnosis, allowing a timely institution of the appropriate treatment. The diagnosis depends on the integration of clinical, laboratory, imaging and histopathologic data. According to the clinical condition, it may be indicated the removal of the offending antigen, the treatment of the underlying disease or specific treatment of the primary vasculitis. The introduction of immunosuppressive therapy with glucocorticoids and cyclophosphamide has revolutionized the prognosis of these patients but, despite its efficacy, it is associated with frequent relapses and significant toxicity. The study of the pathogenesis has been providing more effective and safer diagnostic and therapeutic options, for example B-cell depleting agents, but additional studies are needed to confirm the potential of these alternatives.

  7. Therapeutics in duchenne muscular dystrophy. (United States)

    Strober, Jonathan B


    Duchenne muscular dystrophy (DMD) is a fatal disorder affecting approximately 1 in 3,500 live born males, characterized by progressive muscle weakness. Several different strategies are being investigated in developing a cure for this disorder. Until a cure is found, therapeutic and supportive care is essential in preventing complications and improving the afflicted child's quality of life. Currently, corticosteroids are the only class of drug that has been extensively studied in this condition, with controversy existing over the use of these drugs, especially in light of the multiple side effects that may occur. The use of nutritional supplements has expanded in recent years as researchers improve our abilities to use gene and stem cell therapies, which will hopefully lead to a cure soon. This article discusses the importance of therapeutic interventions in children with DMD, the current debate over the use of corticosteroids to treat this disease, the growing use of natural supplements as a new means of treating these boys and provides an update on the current state of gene and stem cell therapies.

  8. Broad-spectrum antiviral therapeutics.

    Directory of Open Access Journals (Sweden)

    Todd H Rider

    Full Text Available Currently there are relatively few antiviral therapeutics, and most which do exist are highly pathogen-specific or have other disadvantages. We have developed a new broad-spectrum antiviral approach, dubbed Double-stranded RNA (dsRNA Activated Caspase Oligomerizer (DRACO that selectively induces apoptosis in cells containing viral dsRNA, rapidly killing infected cells without harming uninfected cells. We have created DRACOs and shown that they are nontoxic in 11 mammalian cell types and effective against 15 different viruses, including dengue flavivirus, Amapari and Tacaribe arenaviruses, Guama bunyavirus, and H1N1 influenza. We have also demonstrated that DRACOs can rescue mice challenged with H1N1 influenza. DRACOs have the potential to be effective therapeutics or prophylactics for numerous clinical and priority viruses, due to the broad-spectrum sensitivity of the dsRNA detection domain, the potent activity of the apoptosis induction domain, and the novel direct linkage between the two which viruses have never encountered.

  9. Hydrogels for therapeutic cardiovascular angiogenesis. (United States)

    Rufaihah, Abdul Jalil; Seliktar, Dror


    Acute myocardial infarction (MI) caused by ischemia is the most common cause of cardiac dysfunction. While growth factor or cell therapy is promising, the retention of bioactive agents in the highly vascularized myocardium is limited and prevents sustained activation needed for adequate cellular responses. Various types of biomaterials with different physical and chemical properties have been developed to improve the localized delivery of growth factor and/or cells for therapeutic angiogenesis in ischemic tissues. Hydrogels are particularly advantageous as carrier systems because they are structurally similar to the tissue extracellular matrix (ECM), they can be processed under relatively mild conditions and can be delivered in a minimally invasive manner. Moreover, hydrogels can be designed to degrade in a timely fashion that coincides with the angiogenic process. For these reasons, hydrogels have shown great potential as pro-angiogenic matrices. This paper reviews a few of the hydrogel systems currently being applied together with growth factor delivery and/or cell therapy to promote therapeutic angiogenesis in ischemic tissues, with emphasis on myocardial applications.

  10. On existence and uniqueness of solutions for variational data assimilation (United States)

    Bröcker, Jochen


    Data assimilation is a term from the geosciences and refers to methods for estimating orbits of dynamical models from observations. Variational techniques for data assimilation estimate these orbits by minimising an appropriate cost functional which takes the error with respect to the observations but also deviations of the orbits from the model equations into account. Such techniques are very important in practice. In this contribution, the problem of existence and uniqueness of solutions to variational data assimilation is investigated. Under mild hypotheses a solution to this problem exists. The problem of uniqueness is investigated as well, and several results (which all have analogues in optimal control) are established in the present context. The value function is introduced as the cost of an optimal trajectory starting from a given initial condition. The necessary conditions in combination with an envelope theorem can be used to demonstrate that the solution is unique if and only if the value function is differentiable at the given initial condition. This occurs for all initial conditions except maybe on a set of Lebesgue measure zero. Several examples are studied which demonstrate that non-uniqueness of solutions cannot be ruled out altogether though, which has important consequences in practice. References: J.

  11. Uniqueness Domains in the Workspace of Parallel Manipulators

    CERN Document Server

    Wenger, Philippe


    This work investigates new kinematic features of parallel manipulators. It is well known that parallel manipulators admit generally several direct kinematic solutions for a given set of input joint values. The aim of this paper is to characterize the uniqueness domains in the workspace of parallel manipulators, as well as their image in the joint space. The study focuses on the most usual case of parallel manipulators with only one inverse kinematic solution. The notion of aspect introduced for serial manipulators in [Borrel 86] is redefined for such parallel manipulators. Then, it is shown that it is possible to link several solutions to the forward kinematic problem without meeting a singularity, thus meaning that the aspects are not uniqueness domains. An additional set of surfaces, namely the characteristic surfaces, are characterized which divide the workspace into basic regions and yield new uniqueness domains. This study is illustrated all along the paper with a 3-RPR planar parallel manipulator. An oc...

  12. Absolute Uniqueness of Phase Retrieval with Random Illumination

    CERN Document Server

    Fannjiang, Albert


    Random phase or amplitude illumination is proposed to remove at once all types of ambiguity, trivial or nontrivial, at once from phase retrieval. Almost sure irreducibility is proved for {\\em any} complex-valued object of arbitrary sparsity. While this irreducibility result can be viewed as a probabilistic version of the classical result by Bruck, Sodin and Hayes, it provides a new perspective and an effective method for achieving absolute uniqueness in phase retrieval for {\\em every} object, not just objects outside of a measure-zero set. In particular, almost sure absolute uniqueness is proved for complex-valued objects under a general two-point assumption. For objects of nonnegative real and imaginary parts, absolute uniqueness is proved to hold with probability exponentially close to unity as the object sparsity increases.

  13. Uniqueness: skews bit occurrence frequencies in randomly generated fingerprint libraries. (United States)

    Chen, Nelson G


    Requiring that randomly generated chemical fingerprint libraries have unique fingerprints such that no two fingerprints are identical causes a systematic skew in bit occurrence frequencies, the proportion at which specified bits are set. Observed frequencies (O) at which each bit is set within the resulting libraries systematically differ from frequencies at which bits are set at fingerprint generation (E). Observed frequencies systematically skew toward 0.5, with the effect being more pronounced as library size approaches the compound space, which is the total number of unique possible fingerprints given the number of bit positions each fingerprint contains. The effect is quantified for varying library sizes as a fraction of the overall compound space, and for changes in the specified frequency E. The cause and implications for this systematic skew are subsequently discussed. When generating random libraries of chemical fingerprints, the imposition of a uniqueness requirement should either be avoided or taken into account.

  14. Word from the CSO - CERN’s unique scientific breadth

    CERN Multimedia


    Whilst we are all clearly focused on completion of the LHC and the detectors around it and look forward to a successful start of operations later this year, we should not forget that CERN has yet more to offer in addition to this highest priority programme ‘at the energy frontier’. Indeed, CERN also attracts a large scientific community seizing the opportunities offered by its other facilities. Sometimes I wonder whether we are not too modest and should not emphasize more CERN’s unique scientific breadth. ISOLDE, at the PS Booster, relies on innovative techniques to produce results at the forefront of nuclear physics very cost-effectively. nTOF has provided unique measurements of interest to nuclear technology, nuclear astrophysics and basic nuclear physics, and still has an ambitious programme ahead of it after refurbishment of the target. Another unique facility is the Antiproton Decelerator, at which the study of antimatter is being pursued with ingenious experiment...

  15. Therapeutic potential of fecal microbiota transplantation. (United States)

    Smits, Loek P; Bouter, Kristien E C; de Vos, Willem M; Borody, Thomas J; Nieuwdorp, Max


    There has been growing interest in the use of fecal microbiota for the treatment of patients with chronic gastrointestinal infections and inflammatory bowel diseases. Lately, there has also been interest in its therapeutic potential for cardiometabolic, autoimmune, and other extraintestinal conditions that were not previously considered to be associated with the intestinal microbiota. Although it is not clear if changes in the microbiota cause these conditions, we review the most current and best methods for performing fecal microbiota transplantation and summarize clinical observations that have implicated the intestinal microbiota in various diseases. We also discuss case reports of fecal microbiota transplantations for different disorders, including Clostridium difficile infection, irritable bowel syndrome, inflammatory bowel diseases, insulin resistance, multiple sclerosis, and idiopathic thrombocytopenic purpura. There has been increasing focus on the interaction between the intestinal microbiome, obesity, and cardiometabolic diseases, and we explore these relationships and the potential roles of different microbial strains. We might someday be able to mine for intestinal bacterial strains that can be used in the diagnosis or treatment of these diseases. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

  16. Words matter: distinguishing "personalized medicine" and "biologically personalized therapeutics". (United States)

    Cherny, Nathan I; de Vries, Elisabeth G E; Emanuel, Linda; Fallowfield, Lesley; Francis, Prudence A; Gabizon, Alberto; Piccart, Martine J; Sidransky, David; Soussan-Gutman, Lior; Tziraki, Chariklia


    "Personalized medicine" has become a generic term referring to techniques that evaluate either the host or the disease to enhance the likelihood of beneficial patient outcomes from treatment interventions. There is, however, much more to personalization of care than just identifying the biotherapeutic strategy with the highest likelihood of benefit. In its new meaning, "personalized medicine" could overshadow the individually tailored, whole-person care that is at the bedrock of what people need and want when they are ill. Since names and definitional terms set the scope of the discourse, they have the power to define what personalized medicine includes or does not include, thus influencing the scope of the professional purview regarding the delivery of personalized care. Taxonomic accuracy is important in understanding the differences between therapeutic interventions that are distinguishable in their aims, indications, scope, benefits, and risks. In order to restore the due emphasis to the patient and his or her needs, we assert that it is necessary, albeit belated, to deconflate the contemporary term "personalized medicine" by taxonomizing this therapeutic strategy more accurately as "biologically personalized therapeutics" (BPT). The scope of truly personalized medicine and its relationship to biologically personalized therapeutics is described, emphasizing that the best of care must give due recognition and emphasis to both BPT and truly personalized medicine.

  17. Soft Interaction in Liposome Nanocarriers for Therapeutic Drug Delivery

    Directory of Open Access Journals (Sweden)

    Domenico Lombardo


    Full Text Available The development of smart nanocarriers for the delivery of therapeutic drugs has experienced considerable expansion in recent decades, with the development of new medicines devoted to cancer treatment. In this respect a wide range of strategies can be developed by employing liposome nanocarriers with desired physico-chemical properties that, by exploiting a combination of a number of suitable soft interactions, can facilitate the transit through the biological barriers from the point of administration up to the site of drug action. As a result, the materials engineer has generated through the bottom up approach a variety of supramolecular nanocarriers for the encapsulation and controlled delivery of therapeutics which have revealed beneficial developments for stabilizing drug compounds, overcoming impediments to cellular and tissue uptake, and improving biodistribution of therapeutic compounds to target sites. Herein we present recent advances in liposome drug delivery by analyzing the main structural features of liposome nanocarriers which strongly influence their interaction in solution. More specifically, we will focus on the analysis of the relevant soft interactions involved in drug delivery processes which are responsible of main behaviour of soft nanocarriers in complex physiological fluids. Investigation of the interaction between liposomes at the molecular level can be considered an important platform for the modeling of the molecular recognition processes occurring between cells. Some relevant strategies to overcome the biological barriers during the drug delivery of the nanocarriers are presented which outline the main structure-properties relationships as well as their advantages (and drawbacks in therapeutic and biomedical applications.

    Full Text Available Aniruddha Agarwal, Mohamed K Soliman, Yasir J Sepah, Diana V Do, Quan Dong Nguyen Ocular Imaging Research and Reading Center, Stanley M. Truhlsen Eye Institute, University of Nebraska Medical Center, Omaha, USA Abstract: Diabetes and its microvascular complications in patients poses a significant challenge and constitutes a major health problem. When it comes to manifestations in the eye, each case of diabetic retinopathy (DR is unique, in terms of the phenotype, genotype, and, more importantly, the therapeutic response. It is therefore important to identify factors that distinguish one patient from another. Personalized therapy in DR is a new trend aimed at achieving maximum therapeutic response in patients by identifying genotypic and phenotypic factors that may result in less than optimal response to conventional therapy, and consequently, lead to poorer outcome. With advances in the identification of these genetic markers, such as gene polymorphisms and human leucocyte antigen associations, as well as development of drugs that can target their effects, the future of personalized medicine in DR is promising. In this comprehensive review, data from various studies have been analyzed to present what has been achieved in the field of pharmacogenomics thus far. An insight into future research is also provided.

  19. The therapeutic potential of truffle fungi: a patent survey

    Directory of Open Access Journals (Sweden)

    Małgorzata Gajos


    Full Text Available The purpose of this article is to research and retrieve patent information regarding the therapeutic use of truffles. Truffles have a unique value as a foodstuff and impact positively on human health and well-being. They are applied in such industries as the pharmaceutical industry and the cosmetic industry. Patent documentation available in the Espacenet network and the Patentscope service were analyzed by key word and patent specifications were examined to describe state of the art and to identify scientific research trends in therapeutic applications of truffles. Medicinal properties of truffles such as the anticancer or cardiovascular effect, a reduction in blood lipids, immunological resistance and increased energy were identified. Other therapeutic benefits include sedative action, prevention of hormonal imbalances in women, pre-menopause symptom relief, senile urethritis and prostate disorders, sleep disorders and increased absorption of calcium from milk. Truffles can also be used to alleviate symptoms of milk intolerance such as diarrhoea or bloating, to ease rheumatic pains and to treat and prevent further development or recurrence of senile cataract.

  20. GPCR-targeting nanobodies: attractive research tools, diagnostics, and therapeutics. (United States)

    Mujić-Delić, Azra; de Wit, Raymond H; Verkaar, Folkert; Smit, Martine J


    G-protein-coupled receptors (GPCRs) represent a major therapeutic target class. A large proportion of marketed drugs exert their effect through modulation of GPCR function, and GPCRs have been successfully targeted with small molecules. Yet, the number of small new molecular entities targeting GPCRs that has been approved as therapeutics in the past decade has been limited. With new and improved immunization-related technologies and advances in GPCR purification and expression techniques, antibody-based targeting of GPCRs has gained attention. The serendipitous discovery of a unique class of heavy chain antibodies (hcAbs) in the sera of camelids may provide novel GPCR-directed therapies. Antigen-binding fragments of hcAbs, also referred to as nanobodies, combine the advantages of both small molecules (e.g., molecular cavity binding, low production costs) and monoclonal antibodies (e.g., high affinity and specificity). Nanobodies are gaining ground as therapeutics and are also starting to find application as diagnostics and as high-quality tools in GPCR research. Herein, we review recent advances in the use of nanobodies in GPCR research.
