Although dissatisfaction is a primary reason for disengagement from outpatient psychiatric care among consumers with serious mental illnesses, little is known about predictors of their satisfaction with medication management visits. The primary purpose of this study was to explore how dimensions of consumer preferences for shared decision making (i.e., preferences for obtaining knowledge about one's mental illness, being offered and asked one's opinion about treatment options, and involvement in treatment decisions) and the therapeutic relationship (i.e., positive collaboration and type of clinician input) were related to visit satisfaction. Participants were 228 Veterans with serious mental illnesses who completed a 19-item self-report questionnaire assessing satisfaction with visits to prescribers (524 assessments) immediately after visits. In this correlational design, a 3-level mixed model with the restricted maximum likelihood estimation procedure was used to examine shared decision-making preferences and therapeutic alliance as predictors of visit satisfaction. Preferences for involvement in treatment decisions was the unique component of shared decision making associated with satisfaction, such that the more consumers desired involvement, the less satisfied they were. Positive collaboration and prescriber input were associated with greater visit satisfaction. When consumers with serious mental illnesses express preferences to be involved in shared decision making, it may not be sufficient to only provide information and treatment options; prescribers should attend to consumers' interest in involvement in actual treatment decisions. Assessment and tailoring of treatment approaches to consumer preferences for shared decision making should occur within the context of a strong therapeutic relationship.

Agarwal, Vinita

2018-06-05

The study aim was to understand the patient description of the therapeutic relationship with their CAM provider in the context of pain self-management. Because pain is a subjective state, its assessment depends on patient perception of and response to pain. For nurses to provide empathetic and compassionate care, there is a need to explicate patient perceptions of the therapeutic relationship to (re)conceptualize models of patient-centered care. Inductive qualitative content analysis of patient interviews was conducted to identify how patients described therapeutic relationship themes and understand self-management of pain. Participants were individuals working with a CAM practitioner and solicited through purposive and snowball sampling in collaboration with the practitioners from the mid-Atlantic region of the United States in 2016 (N=13). Verbatim transcriptions of audio-recorded semi-structured in-depth interviews (430 single-spaced pages approximately) were content analyzed. Patients described the therapeutic relationship with the provider as a (a) giver, who was "in-tune" with their sense of self to support self-affirmation through empathetic listening and (b) guide, who connected the mind and body through their practice to support self-reflective learning. This description of the CAM therapeutic relationship advances understandings of readjustment of patient relationship with pain through the provider's empathetic listening and connecting the mind and the body to support patient self-affirmation of pain experiences and self-reflective learning. The findings illuminate how a feminist standpoint contributes to understandings of the therapeutic relationship that centers patient subjectivity and co-construction of meaning-making processes to support self-management of pain.

Brownie, Sharon; Scott, Robin; Rossiter, Rachel

2016-10-05

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.

The therapeutic relationship between patient and physiotherapist is a central component of patient-centred care and has been positively associated with better physiotherapy clinical outcomes. Despite its influence, we do not know what conditions enable a physiotherapist and patient to establish and maintain a therapeutic relationship. This knowledge has implications for how clinicians approach their interactions with patients and for the development of an assessment tool that accurately reflects the nature of the therapeutic relationship. Therefore, this study's aim was to identify and provide in-depth descriptions of the necessary conditions of engagement of the therapeutic relationship between physiotherapists and patients. Interpretive description was the qualitative methodological orientation used to identify and describe the conditions that reflect and are practically relevant to clinical practice. Eleven physiotherapists with a minimum 5 years of clinical experience and seven adult patients with musculoskeletal disorders were purposively sampled from private practice clinics in Edmonton, Canada. The in-person, semi-structured interviews were completed in a location of the participant's choice and were audio recorded and transcribed. Qualitative content analysis was used to analyze the textual data and constant comparison techniques were integrated to refine the categories and sub-categories. Rigour strategies used throughout the study were peer debrief, interview notes, reflexive journaling, memoing, member reflections, audit trail, and external audit. Four conditions were identified as necessary for establishing a therapeutic relationship: present , receptive , genuine , and committed . These conditions represent the intentions and attitudes of physiotherapists and patients engaging in the clinical interaction. Although distinct, the conditions appear related as being present and receptive create a foundation for being genuine and committed. These

Full Text Available The therapeutic relationship in Cognitive Behavioural Therapy (CBT has been argued to play an essential role in positive outcomes in therapy. However, it is described as necessary and yet, secondary to technique, often receiving little attention in the training of CBT therapists. This case study explores a trainee psychologist’s experience of finding difficulty in feeling authentic and the application of CBT techniques with her client. This difficulty informed the research question; what is the value of the therapeutic relationship in CBT? A hermeneutic approach with a strong emphasis on phenomenology, is used to explore the therapeutic process and the therapeutic relationship that developed between therapist and client. Qualitative descriptions of 11 sessions are divided into themes, these are discussed in relation to what happened in therapy, and are then discussed further regarding discovery and process into the therapeutic relationship. Conclusions from this case study could possibly reveal the value of the therapeutic relationship when working from a CBT approach, and how it seemed to enable the client to achieve her goal in therapy.

This study examined whether the therapeutic relationship in music therapy with children with Autism Spectrum Disorder predicts generalized changes in social skills. Participants (4-7 years, N = 48) were assessed at baseline, 5 and 12 months. The therapeutic relationship, as observed from session videos, and the generalized change in social skills, as judged by independent blinded assessors and parents, were evaluated using standardized tools (Assessment of the Quality of Relationship; ADOS; SRS). Linear mixed effect models showed significant interaction effects between the therapeutic relationship and several outcomes at 5 and 12 months. We found the music therapeutic relationship to be an important predictor of the development of social skills, as well as communication and language specifically.

A critical view on singular therapeutic projects

Fernando Sfair Kinker

2016-04-01

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.

Leaving patients to their own devices? Smart technology, safety and therapeutic relationships.

Science.gov (United States)

Ho, Anita; Quick, Oliver

2018-03-06

This debate article explores how smart technologies may create a double-edged sword for patient safety and effective therapeutic relationships. Increasing utilization of health monitoring devices by patients will likely become an important aspect of self-care and preventive medicine. It may also help to enhance accurate symptom reports, diagnoses, and prompt referral to specialist care where appropriate. However, the development, marketing, and use of such technology raise significant ethical implications for therapeutic relationships and patient safety. Drawing on lessons learned from other direct-to-consumer health products such as genetic testing, this article explores how smart technology can also pose regulatory challenges and encourage overutilization of healthcare services. In order for smart technology to promote safer care and effective therapeutic encounters, the technology and its utilization must be safe. This article argues for unified regulatory guidelines and better education for both healthcare providers and patients regarding the benefits and risks of these devices.

Berry, Katherine; Salter, Amy; Morris, Rohan; James, Susannah; Bucci, Sandra

2018-04-19

Digital health interventions in the form of smartphone apps aim to improve mental health and enable people access to support as and when needed without having to face the stigma they may experience in accessing services. If we are to evaluate mobile health (mHealth) apps and advance scientific understanding, we also need tools to help us understand in what ways mHealth interventions are effective or not. The concept of therapeutic alliance, a measure of the quality of the relationship between a health care provider and a service user, is a key factor in explaining the effects of mental health interventions. The Agnew Relationship Measure (ARM) is a well-validated measure of therapeutic alliance in face-to-face therapy. This study presented the first attempt to (1) explore service users' views of the concept of relationship within mHealth mental health interventions and (2) adapt a well-validated face-to-face measure of therapeutic alliance, the Agnew Relationship Measure (ARM), for use with mHealth interventions. In stage 1, we interviewed 9 mental health service users about the concept of therapeutic alliance in the context of a digital health intervention and derived key themes from interview transcripts using thematic analysis. In stage 2, we used rating scales and open-ended questions to elicit views from 14 service users and 10 mental health staff about the content and face validity of the scale, which replaced the word "therapist" with the word "app." In stage 3, we used the findings from stages 1 and 2 to adapt the measure with the support of a decision-making algorithm about which items to drop, retain, or adapt. Findings suggested that service users do identify relationship concepts when thinking about mHealth interventions, including forming a bond with an app and the ability to be open with an app. However, there were key differences between relationships with health professionals and relationships with apps. For example, apps were not as tailored and

Bedics, Jamie D; Atkins, David C; Comtois, Katherine Anne; Linehan, Marsha M

2012-06-01

The purpose of the present study was to examine theory-driven hypotheses of the therapeutic relationship and patient introject in dialectical behavior therapy (DBT; Linehan, 1993) for the treatment of borderline personality disorder. A total of 14 DBT therapists provided weekly ratings of the therapeutic relationship and patient introject (N=41) during the course of a randomized controlled trial of DBT for the treatment of borderline personality disorder. Using hierarchical linear modeling (Raudenbush & Bryk, 2002), we tested four hypotheses of the therapeutic relationship as predicted by DBT and behavioral theory. Results supported three of our four predicted hypotheses of the therapeutic relationship, including the effective use of balancing autonomy and control in the therapeutic relationship, the importance of therapists' maintaining a nonpejorative stance toward the patient, and the use of therapist warmth and autonomy as a contingency for improved intrapsychic outcome. Results did not support a modeling hypothesis of the therapeutic relationship. The study supported a DBT and behavioral model of the therapeutic relationship from the perspective of the treating clinician. PsycINFO Database Record (c) 2012 APA, all rights reserved.

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

Ana Sfoggia

2014-03-01

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.

Terapeutický potenciál vzťahov z hľadiska dvoch rovín komunikácie (Therapeutic Potential of Relationships

Directory of Open Access Journals (Sweden)

Reginald A. Slavkovský

2013-06-01

Full Text Available In my paper I deal with connections between relationships, their philosophical reflection and therapy. As a relationship I think here particularly a (therapeutic relationship between two or more people, but also man's relationship to other realities and to himself. It turns out that the basic dynamics of the therapeutic relationship of somebody to himself or herself is determined by entering into specific relationships to others, especially to other people. Different methodological approaches can in different ways contribute to the understanding of the therapeutic dimension of relationships. A look at interpersonal relations from the perspective of communication presents significant contribution to the understanding of these interpersonal relations. Therapeutic approach through relationship is a good option anywhere the pathology of living out and of behaviour probably has its roots in the relationships. In order to understand various types of pathology in communication, and based on that then to search for an appropriate therapeutic approach, it is useful to distinguish two levels of communication, which different authors label in different ways, because they come to them through diverse paths, often as a result of analogy with other area of life. I introduce some concepts of analysis of communication in terms of their therapeutic potential.

Reciprocity in therapeutic relationships: A conceptual review.

Science.gov (United States)

Sandhu, Sima; Arcidiacono, Eleonora; Aguglia, Eugenio; Priebe, Stefan

2015-12-01

Reciprocity has generally been understood as a process of giving and taking, within an exchange of emotions or services, and has long been recognized as a central part of human life. However, an understanding of reciprocity in professional helping relationships has seldom received attention, despite movements in mental health care towards more collaborative approaches between service users and professionals. In this review, a systematic search of the published papers was conducted in order to explore how reciprocity is conceptualized and understood as part of the dyadic therapeutic relationship between professionals and service users. Eleven papers met our inclusion criteria and a narrative synthesis was used to synthesize the key concepts of reciprocity. The concepts of: 'dynamic equilibrium', 'shared affect', 'asymmetric alliance', and 'recognition as a fellow human being' were recurrent in understandings of reciprocity in professional contexts. These conceptualizations of reciprocity were also linked to specific behavioural and psychological processes. The findings suggest that reciprocity may be conceptualized and incorporated as a component of mental health care, with recurrent and observable processes which may be harnessed to promote positive outcomes for service users. To this end, we make recommendations for further research to progress and develop reciprocal processes in mental health care. © 2015 Australian College of Mental Health Nurses Inc.

Diener, Marc J; Monroe, Joel M

2011-09-01

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). (c) 2011 APA, all rights reserved.

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

2013-09-01

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

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

KAUST Repository

Joekar-Niasar, Vahid

2012-02-23

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).

Case formulation and the therapeutic relationship: the role of therapist self-reflection and self-revelation.

Science.gov (United States)

Tufekcioglu, Sumru; Muran, J Christopher

2015-05-01

This article examines the role of the therapist's self-reflection and self-revelation in case formulation. We believe that a collaboratively constructed case formulation must always be considered in the context of an evolving therapeutic relationship. Further, self-reflection and self-revelation on the part of the therapist are critical for a more elaborate and nuanced case formulation and for understanding the patient. This highlights the importance of attunement to the here and now and the evolving therapeutic relationship. From this attunement, the therapist's self-reflection and self-revelation can emerge further, which can lead to the patient's personal growth and increased self-other awareness. To illustrate our point, we present an integrative, relational model in the case of a patient who has been in treatment. © 2015 Wiley Periodicals, Inc.

Manfrida, Gianmarco; Albertini, Valentina; Eisenberg, Erica

2017-01-01

The article explores the different types of therapeutic relationship that can evolve both on- and offline, thanks to the use of tools, such as software and applications, which enable therapists and patients contact outside of the traditional setting. Given the premise that it is practically impossible today to maintain a relationship without the use of internet and telephones, it becomes necessary to question the ways in which the online space can become a useful extension of the therapeutic setting. The authors, starting from a consideration regarding the specificity of the online therapeutic relationship, analyze the best ways to use text and email messaging with patients. Furthermore, specific interactions via group chats are presented, for example, to coordinate a therapeutic team involving several professionals. Further, video chat settings are discussed through a clinical case presentation. Lastly, the therapist's management of social networks is debated, underscoring the importance for the therapists that his or her online identity be consistent with the offline image which patients are introduced to in the traditional setting of the therapy room.

Tele-analysis: the use of media technology in psychotherapy and its impact on the therapeutic relationship.

Science.gov (United States)

Roesler, Christian

2017-06-01

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.

Intimidades: confianza, gender, and hierarchy in the construction of Latino-Latina therapeutic relationships.

Science.gov (United States)

Bracero, W

1998-01-01

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.

The unique relationship between fear of cognitive dyscontrol and self-reports of problematic drinking.

Science.gov (United States)

Koven, Nancy S; Heller, Wendy; Miller, Gregory A

2005-03-01

Research has established positive associations between anxiety sensitivity (AS) and problematic drinking in clinical samples. The present study confirmed this relationship in a nonclinical sample (N=162) and investigated which AS dimension best predicts self-reports of problematic drinking. Only one AS facet, fear of cognitive dyscontrol (FCC), was associated with symptoms of alcohol dependence, severity of drinking problems, and alcohol-related expectations of global, positive changes, sexual enhancement, and tension reduction. The possible role of depression in these relationships was also evaluated. A series of hierarchical regressions revealed that, when trait anxiety, anxious arousal, and anxious apprehension were statistically removed, depression did not contribute significant variance beyond the effects of FMC and other anxiety measures. Results suggest that FCC is uniquely associated with self-reports of problematic drinking behaviors and attitudes. Implications for tension-reduction models of alcohol are discussed.

Cancer rehabilitation is tailored to address the physical or psychosocial decline in ability to engage in daily activities. Its use is supported by high-quality international, multicentre research. Incorporating strategies for self-management behaviour development into rehabilitation can prepare individuals for cancer survivorship. However, healthcare professionals will need to adjust their therapeutic interactions accordingly. Research is yet to clarify the impact of the therapeutic relationship on rehabilitation outcomes in cancer. This study aims to explore the impact of therapeutic relationships on self-management behaviours after cancer. This qualitative study aims to understand cancer rehabilitation participants' beliefs regarding the importance of therapeutic relationships in developing self-management behaviours. A sample representative of a local cancer rehabilitation cohort will be asked to complete a semistructured interview to identify their perspectives on the importance of therapeutic relationships in cancer rehabilitation. Data obtained from the interviews will be analysed, coded and entered into a Delphi questionnaire for circulation to a local cancer rehabilitation population to determine if the views expressed by the interviewees are supported by group consensus. This study was approved by Wales Research Ethics Committee 6 (15/WA/0331) in April 2016. Findings will be disseminated through the first author's doctoral thesis; peer-reviewed journals; local, national and international conference presentations; and public events involving research participants and the general public.

Full Text Available The schizophrenia is a chronic psychosis with serious social and functional consequences, demanding multiples ways of care in its treatment. This research aimed at describing the evolution of a patient taken ill with paranoid schizophrenia, by means of the adoption of the Therapeutic Relationship process, as a modality of nursing psychiatric care, registered in a field diary as narratives of life experiences, during ten meeting days in one psychiatric service of Fortaleza. It was perceived that the application of the Therapeutic Relationship, gradually, enabled to the studied client the confrontation of personal conflicts (complicated family dynamics, rejection and depression and the satisfaction of basic needs such as the communication and group interaction. Therein, the Therapeutic Relationship is considered a primordial care technique in the reintegration and reorganization of the schizophrenic client, as well as in the search of a better quality of life.

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 to investigate why acute

The relationship of therapeutic alliance and outcome is investigated in outpatient behavior therapies of children and adolescents with externalizing problem behavior. Therapist-patient and therapist-parent relationships were evaluated twice during the therapies of N = 53 patients using German relationship questionnaires adapted for use in child and adolescent psychotherapy (BeKi). Pre-post symptom reduction in parent and patient rating, treatment satisfaction as rated by therapist, parent and patient as well as child's global functioning by therapist rating are examined as outcome parameters. The correlations between therapeutic alliance and symptom reduction vary depending on the rater between absence of correlation and high correlation (maximum: r = .53). Most correlations are low to moderate. These results are comparable to those reported in recently published meta-analyses and studies of adult psychotherapy. There are moderate correlations between therapist-patient and therapist-parent alliance and treatment satisfaction and low to moderate correlations with improvements in the children's global functioning. Only few studies have focused on treatment satisfaction and improvements in children's global functioning as outcome variables. Besides symptom reduction, these two variables also correlate significantly with the therapist-patient and therapist-parent alliance. Because correlations highly depend on the rater, future studies should consider the various perspectives.

Gallium a unique anti-resorptive agent in bone: Preclinical studies on its mechanisms of action

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

Pharmacokinetics and concentration-effect relationships of therapeutic monoclonal antibodies and fusion proteins.

Ternant, David; Paintaud, Gilles

2005-09-01

Although monoclonal antibodies (mAbs) constitute a major advance in therapeutics, their pharmacokinetic (PK) and pharmacodynamic (PD) properties are not fully understood. Saturable mechanisms are thought to occur in distribution and elimination of mAbs, which are protected from degradation by the Brambell's receptor (FcRn). The binding of mAbs to their target antigen explains part of their nonlinear PK and PD properties. The interindividual variability in mAb PK can be explained by several factors, including immune response against the biodrug and differences in the number of antigenic sites. The concentration-effect relationships of mAbs are complex and dependent on their mechanism of action. Interindividual differences in mAb PD can be explained by factors such as genetics and clinical status. PK and concentration-effect studies are necessary to design optimal dosing regimens. Because of their above-mentioned characteristics, the interindividual variability in their dose-response relationships must be studied by PK-PD modelling.

Covering spaces of graphs have long been useful for studying expanders (as "graph lifts") and unique games (as the "label-extended graph"). In this paper we advocate for the thesis that there is a much deeper relationship between computational topology and the Unique Games Conjecture. Our starting point is Linial's 2005 observation that the only known problems whose inapproximability is equivalent to the Unique Games Conjecture - Unique Games and Max-2Lin - are instances of Maximum Section of...

Full Text Available Background: Antipsychotic-induced weight gain (AIWG and other adverse metabolic effects represent serious side effects faced by many patients with psychosis that can lead to numerous comorbidities and which reduce the lifespan. While the pathophysiology of AIWG remains poorly understood, numerous studies have reported a positive association between AIWG and the therapeutic benefit of antipsychotic medications.Objectives: To review the literature to (1 determine if AIWG is consistently associated with therapeutic benefit and (2 investigate which variables may mediate such an association.Data Sources: MEDLINE, Google Scholar, Cochrane Database and PsycINFO databases were searched for articles containing all the following exploded MESH terms: schizophrenia [AND] antipsychotic agents/neuroleptics [AND] (weight gain [OR] lipids [OR] insulin [OR] leptin [AND] treatment outcome. Results were limited to full-text, English journal articles.Results: Our literature search uncovered 31 independent studies which investigated an AIWG-therapeutic benefit association with a total of 6063 enrolled individuals diagnosed with schizophrenia or another serious mental illness receiving antipsychotic medications. Twenty-two studies found a positive association while, 10 studies found no association and one study reported a negative association. Study variables including medication compliance, sex, ethnicity, or prior antipsychotic exposure did not appear to consistently affect the AIWG-therapeutic benefit relationship. In contrast, there was some evidence that controlling for baseline BMI/psychopathology, duration of treatment and specific agent studied [i.e., olanzapine (OLZ or clozapine (CLZ] strengthened the relationship between AIWG and therapeutic benefit.Limitations: There were limitations of the reviewed studies in that many had small sample sizes, and/or were retrospective. The heterogeneity of the studies also made comparisons difficult and publication bias

Examining the therapeutic relationship and confronting resistances in psychodynamic psychotherapy: a certified public accountant case.

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

2011-05-01

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.

The present study explored the role of the therapeutic relationship and introject during the course of dialectical behavior therapy (DBT; Linehan, 1993) for the treatment of borderline personality disorder. Women meeting DSM-IV criteria for borderline personality disorder (N = 101) were randomized to receive DBT or community treatment by experts. The Structural Analysis of Social Behavior (Benjamin, 1974) was used to measure both the therapeutic relationship and introject. Relative to community treatment by experts, DBT participants reported the development of a more positive introject, including significantly greater self-affirmation, self-love, self-protection, and less self-attack, during the course of treatment and 1-year follow-up. The therapeutic relationship did not have an independent effect on intrapsychic or symptomatic outcome but did interact with treatment. DBT participants who perceived their therapist as affirming and protecting reported less frequent occurrences of nonsuicidal self-injury. The study showed positive intrapsychic change during DBT and emphasized the importance of affirmation and control in the therapeutic relationship. Results are discussed in the context of understanding the mechanisms of change in DBT. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

Pharmacokinetic and pharmacodynamic considerations for the next generation protein therapeutics.

Shah, Dhaval K

2015-10-01

Increasingly sophisticated protein engineering efforts have been undertaken lately to generate protein therapeutics with desired properties. This has resulted in the discovery of the next generation of protein therapeutics, which include: engineered antibodies, immunoconjugates, bi/multi-specific proteins, antibody mimetic novel scaffolds, and engineered ligands/receptors. These novel protein therapeutics possess unique physicochemical properties and act via a unique mechanism-of-action, which collectively makes their pharmacokinetics (PK) and pharmacodynamics (PD) different than other established biological molecules. Consequently, in order to support the discovery and development of these next generation molecules, it becomes important to understand the determinants controlling their PK/PD. This review discusses the determinants that a PK/PD scientist should consider during the design and development of next generation protein therapeutics. In addition, the role of systems PK/PD models in enabling rational development of the next generation protein therapeutics is emphasized.

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

Community health workers (CHWs) have a unique position between communities and the health sector. The strength of CHWs' relationships with both sides influences their motivation and performance. This qualitative comparative study aimed at understanding similarities and differences in how relationships between CHWs, communities and the health sector were shaped in different Sub-Saharan African settings. The study demonstrates a complex interplay of influences on trust and CHWs' relationships with their communities and actors in the health sector. Mechanisms influencing relationships were feelings of (dis)connectedness, (un)familiarity and serving the same goals, and perceptions of received support, respect, competence, honesty, fairness and recognition. Sometimes, constrained relationships between CHWs and the health sector resulted in weaker relationships between CHWs and communities. The broader context (such as the socio-economic situation) and programme context (related to, for example, task-shifting, volunteering and supervision) in which these mechanisms took place were identified. Policy-makers and programme managers should take into account the broader context and could adjust CHW programmes so that they trigger mechanisms that generate trusting relationships between CHWs, communities and other actors in the health system. This can contribute to enabling CHWs to perform well and responding to the opportunities offered by their unique intermediary position.

A cross-cultural investigation into the relationships among parental support for basic psychological needs, sense of uniqueness, and happiness.

2014-01-01

A significant number of empirical studies have reported that parental support for basic psychological needs is a robust correlate of adolescent happiness. Yet, less is known about the mechanisms responsible for this link. The present study proposed a model suggesting that personal sense of uniqueness explains why satisfaction of basic psychological needs in parent-child relationships is related to happiness. This mediational model was tested among late adolescents in Turkey and the United States. Analyses relying on structural equation modeling and bootstrapping supported the model in both cultures. Implications of the findings for theory and cross-cultural research are discussed. Directions for future research that could improve our understanding of the dynamic interplay between basic needs, sense of uniqueness and well-being are provided.

The Scale to Assess the Therapeutic Relationship in Community Mental Health Care (STAR) is a frequently-administered tool for measuring therapeutic relationships between clinicians and patients. This manuscript tested the STAR's psychometric properties within a community health worker (CHW)-led intervention study involving pregnant and postpartum women. Women (n = 141) enrolled in the study completed the 12-item participant STAR survey (STAR-P) at two time points over the course of pregnancy and at two time points after delivery. The factor structure of the STAR-P proved to be unstable with this population. However, a revised 9-item STAR-P revealed a two-factor model of positive and negative interactions, and demonstrated strong internal consistency at postpartum time points. The revised STAR-P shows strong psychometric properties, and is suitable for use to evaluate the relationship developed between CHWs and pregnant and postpartum women in an intervention program.

As part of the national OpenNotes initiative, the Veterans Health Administration (VHA) provides veterans online access to their clinical progress notes, raising concern in mental health settings. The aim of this study was to examine the perspectives and experiences of mental health clinicians with OpenNotes to better understand how OpenNotes may be affecting mental health care. We conducted individual semi-structured interviews with 28 VHA mental health clinicians and nurses. Transcripts were analyzed using a thematic analysis approach, which allows for both inductive and deductive themes to be explored using an iterative, constant comparative coding process. OpenNotes is changing VHA mental health care in ways that mental health clinicians perceive as both challenging and beneficial. At the heart of these changes is a shifting power distribution within the patient-clinician relationship. Some clinicians view OpenNotes as an opportunity to better partner with patients, whereas others feel that it has the potential to undo the therapeutic relationship. Many clinicians are uncomfortable with OpenNotes, but acknowledge that this discomfort could both improve and diminish care and documentation practices. Specifically, we found that (1) OpenNotes is empowering patients, (2) OpenNotes is affecting how clinicians build and maintain the therapeutic relationship, and (3) mental health clinicians are adjusting their practices to protect patients and themselves from adverse consequences of OpenNotes. Our findings suggest that future research should monitor whether OpenNotes notes facilitates stronger patient-clinician relationships, enhancing patient-centered mental health care, or diminishes the quality of mental health care through disruptions in the therapeutic relationship and reduced documentation. ©United States Government.

Abstract Rationale: We report a unique case of a tripartite esophageal collision tumor consisting of three separate histologic types. Patients concerns: Therapeutic dilemmas on the proper treatment of those rare neoplasms remain unanswered considering both proper surgical therapy and adjuvant therapy. Diagnose: In this paper, we report a unique case of a patient with a tripartite esophageal collision tumor consisting of a small cell carcinoma, an adenocarcinoma of medium differentiation and a signet ring cell carcinoma. Diagnosis is difficult as clinical presentation of the patient was undistinguishable from other, commoner tumor types. Interventions: The patient's diagnostic and therapeutic course along with available data on the collisions tumor's biological behavior and treatment are briefly discussed. Outcomes: Esophagectomy is the best treatment options for these patients. Unique nature of this tumor demands aggresive oncologic treatment. Lessons: Collision tumors are rare neoplasms consisting of distinct cell populations developing in juxtaposition to one another without any areas of intermingling. Various cell types can be found. However, collision neoplasms of the esophagus combining adenomatous and neuroendocrine components are exceedingly rare, with only 5 cases described to date in the literature. Given their rarity, limited information is available on their tumorigenesis, biological behavior and clinical course. In general, these tumors are aggressive neoplasms and significantly affect patient treatment and prognosis. PMID:29245236

The patient relationship and therapeutic techniques of the South Sotho traditional healer.

Pinkoane, M G; Greeff, M; Williams, M J S

2005-11-01

Until 1996 the practice of traditional healers was outlawed in South Africa and not afforded a legal position in the community of health care providers. In 1978 the World Health Organization (WHO) identified traditional healers as those people forming an essential core of primary health care workers for rural people in the Third World Countries. However in 1994 the new South African government identified traditional healers as forming an essential element of primary health care workers. It is estimated that 80% of the black population uses traditional medicine because it is deeply rooted in their culture, which is linked to their religion. The traditional healer shares with the patient a world view which is completely alien to biomedical personnel. Therapeutic techniques typically used in traditional healing conflict with the therapeutic techniques used in biomedicine. The patients' perceptions of traditional healing, their needs and expectations, may be the driving force behind their continuous persistence to consult a traditional healer, even after these patients may have sought the therapeutic techniques of biomedical personnel. The operation of both systems in the same society creates a problem to both providers and recipients of health care. Confusion then arises and the consumer consequently chooses the services closer to her. The researcher aimed at investigating the characteristics of the relationship between the traditional healers and the patients, explored the therapeutic techniques that are used in the South Sotho traditional healing process, and investigated the views of both the traditional healers and the patients about the South -Sotho traditional healing process, to facilitate incorporation of the traditional healers in the National Health Care Delivery System. A qualitative research design was followed. Participants were identified by means of a non-probable, purposive voluntary sample. Data was collected by means of a video camera and semi

Ethical issues in the qualitative researcher--participant relationship.

Eide, Phyllis; Kahn, David

2008-03-01

Qualitative research poses ethical issues and challenges unique to the study of human beings. In developing the interpersonal relationship that is critical to qualitative research, investigator and participant engage in a dialogic process that often evokes stories and memories that are remembered and reconstituted in ways that otherwise would not occur. Ethical issues are raised when this relationship not only provides qualitative research data, but also leads to some degree of therapeutic interaction for the participant. The purpose of this article is to examine some of the controversies inherent in the researcher's dilemma when this occurs, set within the context of a nursing caring theory (Swanson), and the International Council of Nurses Code of ethics for nurses, which provides guidance on global nursing practice.

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

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

The purpose of this study is to describe the therapeutic approach to a patient's criminal offense in a forensic mental health nurse-patient relationship from the nurse's perspective. Eight nurses in a Finnish forensic psychiatric hospital were interviewed, and the resultant research material was analyzed by inductive content analysis. The results revealed the process of the therapeutic approach to a patient's offense, which comprises numerous steps and various phases. For the nurse, the process of working through the offense can be divided into stages in which an attempt is made to respond to the patient's behavior and interaction in a manner that leads to working through the criminal act. © 2016 Wiley Periodicals, Inc.

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.

Oncolytic Viruses: Therapeutics With an Identity Crisis

Directory of Open Access Journals (Sweden)

Caroline J. Breitbach

2016-07-01

Full Text Available 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.

Mindful Processing in Psychotherapy - Facilitating Natural Healing Process within Attuned Therapeutic Relationship

Directory of Open Access Journals (Sweden)

Gregor Žvelc

2012-06-01

Full Text Available Mindfulness is non-judgmental, accepting awareness of what is going on in the present moment. The author proposes that mindfulness promotes natural healing of the organism, where the change comes spontaneously by acceptance and awareness of internal experience. Such process the author describes as ‘mindful processing’, because with mindful awareness disturbing experiences can be processed and integrated. The author’s interest in how mindfulness can be systematically applied in psychotherapy led to the development of the ‘mindful processing’ method, which invites the client to become aware of the moment-to-moment subjective experience. The method is used within attuned therapeutic relationship and thetheoretical framework of Integrative Psychotherapy. Mindful Processing is not goal-oriented and doesn’t strive to achieve a positive outcome. Such an outcome is a natural by-product of accepting awareness of both pleasant and unpleasant inner experience (body sensations, affects and/or thoughts. The method is illustrated with a transcript of a session with commentary.

Social Workers' Reflections on the Therapeutic Encounter With Elder Abuse and Neglect.

2016-02-24

The aim of this qualitative study was to explore social workers' reflections on their experience of the therapeutic encounter with victims and perpetrators of elder abuse and neglect. The research questions were as follows: How do social workers tune themselves toward the therapeutic encounter with elder abuse? How do they position themselves vis-à-vis the clients? How do social workers describe the meaning of the intervention both for the clients and for themselves? What is the added value of the therapeutic encounter in this field for the social workers? Participants were 17 experienced women social workers, who worked with abusers and with abused and neglected older adults in Israel. Data were collected via in-depth semi-structured interviews, which were later transcribed and content analyzed. Two main themes emerged from the findings, emphasizing two key aspects of the social workers' reflective process experienced during the therapeutic encounter: (a) focus on the client: "This is the journey of their lives"-reflection on the therapeutic "journey"; (b) focus on the social worker's inner and professional world: "'There is nothing to be done' is no longer in my vocabulary"-a personal and professional maturation process. The social workers expressed a positive attitude toward their elder clients. A unique dialogue developed in the therapeutic encounter, whereby the social workers considered any change as valuable if it allowed the elders a sense of control and self-worth, whereas the social workers were enriched by the elders' life experience, and matured both personally and professionally. Thus, both sides benefited from this reciprocal relationship. Implications for further research and practice are discussed. © The Author(s) 2016.

Insulin receptors (IRs) in the brain have unique molecular features and a characteristic pattern of distribution. Their possible functions extend beyond glucose utilization. In this systematic review, we explore the interactions between insulin and the brain and its implications for anesthesiologists, critical care physicians, and other medical disciplines. A literature search of published preclinical and clinical studies between 1978 and 2014 was conducted, yielding 5996 articles. After applying inclusion and exclusion criteria, 92 studies were selected for this systematic review. The IRs have unique molecular features, pattern of distribution, and mechanism of action. It has effects on neuronal function, metabolism, and neurotransmission. The IRs are involved in neuronal apoptosis and neurodegenerative processes. In this systematic review, we present a close relationship between insulin and the brain, with discernible effects on memory, learning abilities, and motor functions. The potential therapeutic effects extend from acute brain insults such as traumatic brain injury, brain ischemia, and hemorrhage, to chronic neurodegenerative diseases such as Alzheimer and Parkinson disease. An understanding of the wider effects of insulin conveyed in this review will prompt anaesthesiologists and critical care physicians to consider its therapeutic potential and guide future studies. © The Author(s) 2015.

Prayer as therapeutic process toward transforming destructiveness within a spiritual direction relationship.

Kuchan, Karen L

2011-03-01

This article will expand previous conceptualizations (Kuchan, Presence Int J Spiritual Dir 12(4):22-34, 2006; J Religion Health 47(2):263-275, 2008; J Pastoral Care Counsel, forthcoming) of what might be occurring during a prayer practice that creates space within a spiritual direction relationship for the creation of inner images that reveal a person's unconscious relational longings and co-created representations of God that seem to facilitate therapeutic process toward aliveness. In previous articles, I suggest one way to understand the prayer experience is through a lens of Winnicottian notions of transitional space, illusion, and co-creation of God images. This article expands on these ideas to include an understanding of God as Objective Other (Lewis, The four loves, 1960) interacting with a part of a person's self (Jung, in: The structure and dynamics of the psyche, collected works 8, 1934; Symington, Narcissism, a new theory, 1993) that has capacity for subjectivity (Benjamin, Like subjects, love objects: Essays on recognition and sexual difference, 1995) and co-creation (Winnicott, Home is where we start from: Essays by a psychoanalyst, 1990), of inner representations of God (Ulanov, Winnicott, god and psychic reality, 2001). I also expand on a notion of God as "Source of aliveness" by integrating an aspect of how Symington (Narcissism, a new theory, 1993) thinks about "the lifegiver," which he understands to be a mental object. After offering this theoretical expansion of the prayer practice/experience, one woman's inner representations of self and God are reflected upon in terms of a therapeutic process toward transforming destructiveness, utilizing ideas from Winnicott, Kohut, and Benjamin.

The relationship between alliance and outcome has traditionally been studied based on measures that assess these therapy factors at a global level. However, the specific variations of the alliance process and their association with therapy segments that are relevant for change have not yet been fully examined. The present study examines the variations in the therapeutic alliance in 73 significant in-session events: 35 change and 38 stuck episodes identified through the observation of 14 short-term therapies of different theoretical orientations. Variations in the alliance were assessed using the VTAS-SF [Shelef, K., & Diamond, G. (2008). Short form of the revised Vanderbilt Therapeutic Alliance Scale: Development, reliability, and validity. Psychotherapy Research, 18, 433-443]. Nested analyses (HLM) indicate a statistically significant better quality of the alliance during change episodes.

The unique ethics of sports medicine.

Science.gov (United States)

Johnson, Rob

2004-04-01

The ethical code by which physicians traditionally conduct themselves is based on the relationship between the physician and the patient: both work toward the goal of improving or maintaining health. Constraints on this relationship may be behaviors of patient choice (tobacco use, excessive alcohol use, sedentary behavior, and so on). The athlete-physician relationship is ethically different. Influences such as the physician's employer, the athlete's desire to play with pain and injury, and the economic consequences of playing or not complicate medical decisions. This perspective suggests something different and even unique about the ethics of the sports medicine practitioner. This article explores the differences fostering the ethical tight ropes that sports physicians walk in their sports medicine practices.

"What Do You Think We Should Do?": Relationship and Reflexivity in Participant Observation.

Elliot, Michelle L

2015-07-01

This article uses three concepts as a framework by which to examine how the interrelational elements of ethnographic approaches to qualitative inquiry reflect dimensions of therapeutic engagement. Participant observation, reflexivity, and context are all widely and routinely included within research methods; however, they are less frequently attended to directly in their experiential capacity through the lens of the researcher, clinician turned investigator. A unique study design will be profiled to reflect the complicated juxtaposition between methods, questions, sample population, time, space, and identity. Studying occupational therapy students traveling abroad for a short-term immersion experience, this narrative study called on a necessary and attentive awareness of locality as the researcher traveled with the group. Conducting ethnographic research where the researcher's therapeutic skills aided and constrained relationships resulted in rich, guarded, and relevant insights that parallel the therapeutic use of self in occupational therapy practice.

As unique biopolymers, proteins can be employed for therapeutic delivery. They bear important features such as bioavailability, biocompatibility, and biodegradability with low toxicity serving as a platform for delivery of various small molecule therapeutics, gene therapies, protein biologics and cells. Depending on size and characteristic of the therapeutic, a variety of natural and engineered proteins or peptides have been developed. This, coupled to recent advances in synthetic and chemical biology, has led to the creation of tailor-made protein materials for delivery. This review highlights strategies employing proteins to facilitate the delivery of therapeutic matter, addressing the challenges for small molecule, gene, protein and cell transport.

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.

Review of Dialogues on difference: Studies of diversity in the therapeutic relationship.

Consoli, Andrés J

2007-12-01

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.

2006-08-01

Changes in partners' sense of self-in-relationship, which a systemic-constructivist couple therapy (SCCT) induced, led to robust improvement in satisfaction in 2 studies and a follow-up study. In each study, 13 referred couples completed measures of satisfaction, mutuality, similarities, and other-in-self construal pre-post 12 hours of SCCT. The authors reliably coded transcripts of 1st and final sessions for each partner's we-ness, the identity that each partner establishes in relationship to the other. Having met the criteria for the rigorous study of change in single group process-outcome design, changes in we-ness accompanied large posttherapy dyadic increments on all variables in each study. Therapeutic gains appeared at follow-up and correlated with increased we-ness obtained at end of therapy 2 years earlier. The authors raise theoretical implications for all types of couple therapies and explain clinical techniques.

[In the beginning was a relationship].

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).

Individualised cancer therapeutics: dream or reality? Therapeutics construction.

Shen, Yuqiao; Senzer, Neil; Nemunaitis, John

2005-11-01

The analysis of DNA microarray and proteomic data, and the subsequent integration into functional expression sets, provides a circuit map of the hierarchical cellular networks responsible for sustaining the viability and environmental competitiveness of cancer cells, that is, their robust systematics. These technologies can be used to 'snapshot' the unique patterns of molecular derangements and modified interactions in cancer, and allow for strategic selection of therapeutics that best match the individual profile of the tumour. This review highlights technology that can be used to selectively disrupt critical molecular targets and describes possible vehicles to deliver the synthesised molecular therapeutics to the relevant cellular compartments of the malignant cells. RNA interference (RNAi) involves a group of evolutionarily conserved gene silencing mechanisms in which small sequences of double-stranded RNA or intrinsic antisense RNA trigger mRNA cleavage or translational repression, respectively. Although RNAi molecules can be synthesised to 'silence' virtually any gene, even if upregulated, a mechanism for selective delivery of RNAi effectors to sites of malignant disease remains challenging. The authors will discuss gene-modified conditionally replicating viruses as candidate vehicles for the delivery of RNAi.

Zuckerman, Jonathan E; Davis, Mark E

2013-11-01

Nanoparticles are an enabling technology for the creation of tissue-/cell-specific therapeutics that have been investigated extensively as targeted therapeutics for cancer. The kidney, specifically the glomerulus, is another accessible site for nanoparticle delivery that has been relatively overlooked as a target organ. Given the medical need for the development of more potent, kidney-targeted therapies, the use of nanoparticle-based therapeutics may be one such solution to this problem. Here, we review the literature on nanoparticle targeting of the glomerulus. Specifically, we provide a broad overview of nanoparticle-based therapeutics and how the unique structural characteristics of the glomerulus allow for selective, nanoparticle targeting of this area of the kidney. We then summarize literature examples of nanoparticle delivery to the glomerulus and elaborate on the appropriate nanoparticle design criteria for glomerular targeting. Finally, we discuss the behavior of nanoparticles in animal models of diseased glomeruli and review examples of nanoparticle therapeutic approaches that have shown promise in animal models of glomerulonephritic disease.

Mares, Sarah; Robinson, Gary

2012-04-01

Little is written about the process of delivering mainstream, evidence-based therapeutic interventions for Aboriginal children and families in remote communities. Patterns of interaction between parents and children and expectations about parenting and professional roles and responsibilities vary across cultural contexts. This can be a challenging experience for professionals accustomed to work in urban settings. Language is only a part of cultural difference, and the outsider in a therapeutic group in an Aboriginal community is outside not only in language but also in access to community relationships and a place within those relationships. This paper uses examples from Let's Start, a therapeutic parent-child intervention to describe the impact of distance, culture and relationships in a remote Aboriginal community, on the therapeutic framework, group processes and relationships. Cultural and contextual factors influence communication, relationships and group processes in a therapeutic group program for children and parents in a remote Aboriginal community. Group leaders from within and from outside the community, are likely to have complementary skills. Cultural and contextual factors influence communication, relationships and group processes in a therapeutic group program for children and parents in a remote Aboriginal community. Group leaders from within and from outside the community, are likely to have complementary skills. Program adaptation, evaluation and staff training and support need to take these factors into account to ensure cultural accessibility without loss of therapeutic fidelity and efficacy.

Diabetes is one of the diseases that required long treatment. Therapeutic outcome is one of the important factors that affect the quality of life. The purpose of this research is to know the effect of therapeutic result on quality of life in Abdul Azis Singkawang hospital. This study used Cross-sectional design. The inclusion criteria for this study was patients with type 2 diabetes mellitus (T2DM) outpatients over 18 years with ICD code X E.11. This study used the EQ-5D to measure patient's quality of life. We recruited 86 T2DM patients who met the inclusion criteria and were dominated by female respondents around 57%. The average value of quality of life EQ-5D was the index value 0.75±0.22 and visual analog scale 74.02±11.80. The result of the analysis showed that there was significant relationship between income and quality of life (p=0.001) and there was significant correlation between 2-hour PG and quality of life (p=0.037). The conclusion of this study was the therapeutic outcome affect the quality of life in 2-h PG, where the higher 2-h PG showed the low quality of life.

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

Directory of Open Access Journals (Sweden)

Asrar Alam

2014-01-01

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.

This study explores the unique role of Ga in amorphous (a-) In[BOND]Ga[BOND]O oxide semiconductors through combined theory and experiment. It reveals substitutional effects that have not previously been attributed to Ga, and that are investigated by examining how Ga influences structure–property relationships in a series of pulsed laser deposited a-In[BOND]Ga[BOND]O thin films. Element-specific structural studies (X-ray absorption and anomalous scattering) show good agreement with the results of ab initio molecular dynamics simulations. This structural knowledge is used to understand the results of air-annealing and Hall effect electrical measurements. The crystallization temperature of a-IO is shown to increase by as much as 325 °C on substituting Ga for In. This increased thermal stability is understood on the basis of the large changes in local structure that Ga undergoes, as compared to In, during crystallization. Hall measurements reveal an initial sharp drop in both carrier concentration and mobility with increasing Ga incorporation, which moderates at >20 at% Ga content. This decline in both the carrier concentration and mobility with increasing Ga is attributed to dilution of the charge-carrying In[BOND]O matrix and to increased structural disorder. The latter effect saturates at high at% Ga.

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 79years 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. Copyright © 2013 Elsevier B.V. All rights reserved.

Antic, Ana

2014-03-01

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.

In the present study, a unique strategy was developed to develop nanocarriers containing multiple therapeutics with controlled release characteristics. In this study, we demonstrated the synthesis of dextran sulfate-doxorubicin (DS-DOX) and alginate-cisplatin (AL-CIS) polymer-drug complexes to produce a transferrin ligand-conjugated liposome. The targeted nanoparticles (TL-DDAC) were nano-sized and spherical. The targeted liposome exhibited a specific receptor-mediated endocytic uptake in cancer cells. The enhanced cellular uptake of TL-DDAC resulted in a significantly better anticancer effect in resistant and sensitive breast cancer cells compared to that of the free drugs. Specifically, DOX and CIS at a molar ratio of 1:1 exhibited better therapeutic performance compared to that of other combinations. The combination of an anthracycline-based topoisomerase II inhibitor (DOX) and a platinum compound (CIS) resulted in significantly higher cell apoptosis (early and late) in both types of cancer cells. In conclusion, treatment with DS-DOX and AL-CIS based combination liposomes modified with transferrin (TL-DDAC) was an effective cancer treatment strategy. Further investigation in clinically relevant animal models is warranted to prove the therapeutic efficacy of this unique strategy. Copyright © 2017 Elsevier Ltd. All rights reserved.

Botanical polysaccharides: macrophage immunomodulation and therapeutic potential.

Science.gov (United States)

Schepetkin, Igor A; Quinn, Mark T

2006-03-01

Botanical polysaccharides exhibit a number of beneficial therapeutic properties, and it is thought that the mechanisms involved in these effects are due to the modulation of innate immunity and, more specifically, macrophage function. In this review, we summarize our current state of understanding of the macrophage modulatory effects of botanical polysaccharides isolated from a wide array of different species of flora, including higher plants, mushrooms, lichens and algae. Overall, the primary effect of botanical polysaccharides is to enhance and/or activate macrophage immune responses, leading to immunomodulation, anti-tumor activity, wound-healing and other therapeutic effects. Furthermore, botanical and microbial polysaccharides bind to common surface receptors and induce similar immunomodulatory responses in macrophages, suggesting that evolutionarily conserved polysaccharide structural features are shared between these organisms. Thus, the evaluation of botanical polysaccharides provides a unique opportunity for the discovery of novel therapeutic agents and adjuvants that exhibit beneficial immunomodulatory properties.

Need for Uniqueness Determines Reactions to Web-Based Personalized Advertising.

Stiglbauer, Barbara; Kovacs, Carrie

2018-01-01

The presented empirical study among a sample of n = 256 participants addressed the relationship between consumers' need for uniqueness and their reactions to web-based personalized advertising. Drawing on regulatory focus theory, we argue that the consumers' need for uniqueness dimensions creative choice and similarity avoidance may relate to promotion and prevention regulatory orientations, respectively. Accordingly, we hypothesized that creative choice and similarity avoidance would differentially predict self-reported approach and avoidance behavior toward personalized advertising. These direct relationships were further expected to be mediated by subjective evaluations of personalized advertising (i.e., perceived value and irritation). In line with these hypotheses, we found that creative choice predicted approach behavior through increased web-based personalized advertising value, whereas similarity avoidance predicted avoidance behavior through increased irritation. Creative choice also predicted decreased irritation, which in turn was related to decreased approach behavior. In sum, the results suggest that the consumers' need for uniqueness dimensions should not be investigated as a composite, as they seem to reflect different regulatory orientations and are therefore likely to evoke different affective, cognitive, and behavioral responses.

Although widely discussed in theories of eating disorders, the experience of "feeling fat" in this population has received little research attention. This study tested the unique relationships between feeling fat and measures of problematic eating behaviours and attitudes. Data were analysed from individuals with anorexia nervosa (AN; n = 123) and bulimia nervosa (BN; n = 51). Correlations revealed considerable unshared variance between feeling fat and shape and weight over-evaluation and depressive symptoms. Moreover, when over-evaluation and depressive symptoms were controlled, feeling fat predicted unique variance in restraint and eating concerns. Findings offer some support for the idea that feeling fat is a distinct and important component of body image concerns in eating disorders. Further research that develops a standardized measure of feeling fat is required. Further research that examines whether feeling fat is an important treatment mechanism is also needed.

Patrick, Peter D; Wamstad, Julia Buch; Mabry, Jennifer L; Smith-Janik, Shannan; Gurka, Matthew J; Buck, Marcia L; Blackman, James A

2009-06-01

This study examines the relationship between scores on the Western Neuro Sensory Stimulation Profile (WNSSP) and therapeutic participation as it relates to rehabilitation readiness (RR) in adolescents with low response following severe traumatic brain injury (TBI). This is a serial observational design using multiple measures of clinical status and participation. Ten children, mean age 16.7 years, who remained in a low response state (30 days or more) were assessed with the WNSSP and videotaped during physical and occupational therapy sessions. Associations were evaluated between WNSSP scores and participation scores related to arousal, awareness and communication. The WNSSP was only associated with the communication score (p < 0.0001). The arousal and awareness scores had no significant impact on the WNSSP score. These results suggest that scores on the WNSSP may be related to the return of communication skills in adolescents in low response states as one part of assessing their therapeutic participation and ultimate rehabilitation readiness. This ability may assist in making decisions regarding care planning.

Therapeutic Vaccination for HPV Induced Cervical Cancers

2007-01-01

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.

Jain, Arhanth Kumar; Manjunath, Shreevathsa

2016-01-01

The text " Vaidyavallabha " is an authoritative work on Ayurvedic therapeutics written by Hastiruci , a Jain scholar. It belongs to the time period of 1673-1726 CE. Different physical and mental ailments with their treatments are addressed in the 274 verses spanned over eight chapters in this work. In this text many unique, special and simple medicinal preparations for different diseases are given. Many drugs which were easily available in the local area are given much more importance in the treatment. Added to this, method and uniqueness of naming the diseases in the text stand differently when compared to other texts. Even though the text seems to be small, the contribution to the field of Ayurveda practice is priceless.

Sinigrin and Its Therapeutic Benefits

2016-03-01

Full Text Available Sinigrin (allyl-glucosinolate or 2-propenyl-glucosinolate is a natural aliphatic glucosinolate present in plants of the Brassicaceae family, such as broccoli and brussels sprouts, and the seeds of Brassica nigra (mustard seeds which contain high amounts of sinigrin. Since ancient times, mustard has been used by mankind for its culinary, as well as medicinal, properties. It has been systematically described and evaluated in the classical Ayurvedic texts. Studies conducted on the pharmacological activities of sinigrin have revealed anti-cancer, antibacterial, antifungal, antioxidant, anti-inflammatory, wound healing properties and biofumigation. This current review will bring concise information about the known therapeutic activities of sinigrin. However, the information on known biological activities is very limited and, hence, further studies still need to be conducted and its molecular mechanisms also need to be explored. This review on the therapeutic benefits of sinigrin can summarize current knowledge about this unique phytocompounds.

Therapeutic enhancement: nursing intervention category for patients diagnosed with Readiness for Therapeutic Regimen Management.

To present a new nursing intervention category called therapeutic enhancement. Fewer than half of North Americans follow their physician's recommendations for diet and exercise, even when such are crucial to their health or recovery. It is imperative that nurses consider new ways to promote healthy behaviours. Therapeutic enhancement is intended to provide such a fresh approach. Traditional intervention techniques focusing on education, contracts, social support and more frequent interaction with physicians appear not to be effective when used alone. Successful strategies have been multidisciplinary; and have included interventions by professional nurses who assist patients to understand their disease and the disease process and that helps them to develop disease-management and self-management skills. Therapeutic enhancement incorporates The Stages of Change Theory, Commitment to Health Theory, Motivational Interviewing techniques and instrumentation specifically designed for process evaluation of health-promoting interventions. This is a critical review of approaches that, heretofore, have not been synthesised in a single published article. Based on the commonly used Stages of Change model, therapeutic enhancement is useful for patients who are at the action stage of change. Using therapeutic enhancement as well as therapeutic strategies identified in Stages of Change Theory, such as contingency management, helping relationships, counterconditioning, stimulus control and Motivational Interviewing techniques, nursing professionals can significantly increase the chances of patients moving from action to the maintenance stage of change for a specific health behaviour. Using the nursing intervention category, therapeutic enhancement can increase caregivers' success in helping patients maintain healthy behaviours.

The search for effective and non-invasive delivery modules to transport therapeutic molecules across skin has led to the discovery of a number of nanocarriers (viz.: liposomes, ethosomes, dendrimers, etc.) in the last few decades. However, available literature suggests that these delivery modules face several issues including poor stability, low encapsulation efficiency, and scale-up hurdles. Recently, carbon nanotubes (CNTs) emerged as a versatile tool to deliver therapeutics across skin. Superior stability, high loading capacity, well-developed synthesis protocol as well as ease of scale-up are some of the reason for growing interest in CNTs. CNTs have a unique physical architecture and a large surface area with unique surface chemistry that can be tailored for vivid biomedical applications. CNTs have been thus largely engaged in the development of transdermal systems such as tuneable hydrogels, programmable nonporous membranes, electroresponsive skin modalities, protein channel mimetic platforms, reverse iontophoresis, microneedles, and dermal buckypapers. In addition, CNTs were also employed in the development of RNA interference (RNAi) based therapeutics for correcting defective dermal genes. This review expounds the state-of-art synthesis methodologies, skin penetration mechanism, drug liberation profile, loading potential, characterization techniques, and transdermal applications along with a summary on patent/regulatory status and future scope of CNT based skin therapeutics.

The Relations of Family Members’ Unique and Shared Perspectives of Family Dysfunction to Dyad Adjustment

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

2017-01-01

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 to 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. PMID:24884682

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

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.

Plutonium uniqueness

International Nuclear Information System (INIS)

Silver, G.L.

1984-01-01

A standard is suggested against which the putative uniqueness of plutonium may be tested. It is common folklore that plutonium is unique among the chemical elements because its four common oxidation states can coexist in the same solution. Whether this putative uniqueness appears only during transit to equilibrium, or only at equilibrium, or all of the time, is not generally made clear. But while the folklore may contain some truth, it cannot be put to test until some measure of 'uniqueness' is agreed upon so that quantitative comparisons are possible. One way of measuring uniqueness is as the magnitude of the product of the mole fractions of the element at equilibrium. A 'coexistence index' is defined and discussed. (author)

Synthetic Immunology: Hacking Immune Cells to Expand Their Therapeutic Capabilities.

Science.gov (United States)

Roybal, Kole T; Lim, Wendell A

2017-04-26

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.

Therapeutic working alliance: From a psychoanalitical to a pantheoretical conception

Directory of Open Access Journals (Sweden)

Peter Praper

2004-05-01

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.

Imajo, Shuzo

2002-10-01

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.

Research findings show that Narcissistic Personality Disorder symptoms and behaviors will negatively impact interpersonal relationships across all areas of life. CONCLUSIONS AND COMMENT: Nurses interact with diverse populations in a variety of settings. Establishment of a therapeutic relationship with individuals who have Narcissistic Personality Disorder can be aided by a clear understanding of the associated relationship issues.

Unconscious emotional reasoning and the therapeutic misconception.

Science.gov (United States)

Charuvastra, A; Marder, S R

2008-03-01

The "therapeutic misconception" describes a process whereby research volunteers misinterpret the intentions of researchers and the nature of clinical research. This misinterpretation leads research volunteers to falsely attribute a therapeutic potential to clinical research, and compromises informed decision making, therefore compromising the ethical integrity of a clinical experiment. We review recent evidence from the neurobiology of social cognition to provide a novel framework for thinking about the therapeutic misconception. We argue that the neurobiology of social cognition should be considered in any ethical analysis of how people make decisions about participating in clinical trials. The neurobiology of social cognition also suggests how the complicated dynamics of the doctor-patient relationship may unavoidably interfere with the process of obtaining informed consent. Following this argument we suggest new ways to prevent or at least mitigate the therapeutic misconception.

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.

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

2016-07-01

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.

A new therapeutic community: development of a compassion-focussed and contextual behavioural environment.

Science.gov (United States)

Veale, David; Gilbert, Paul; Wheatley, Jon; Naismith, Iona

2015-01-01

Social relationships and communities provide the context and impetus for a range of psychological developments, from genetic expression to the development of core self-identities. This suggests a need to think about the therapeutic changes and processes that occur within a community context and how communities can enable therapeutic change. However, the 'therapeutic communities' that have developed since the Second World War have been under-researched. We suggest that the concept of community, as a change process, should be revisited within mainstream scientific research. This paper briefly reviews the historical development of therapeutic communities and critically evaluates their current theory, practice and outcomes in a systematic review. Attention is drawn to recent research on the nature of evolved emotion regulation systems, the way these are entrained by social relationships, the importance of affiliative emotions in the regulation of threat and the role of fear of affiliative emotions in psychopathology. We draw on concepts from compassion-focussed therapy, social learning theory and functional analytical psychotherapy to consider how members of a therapeutic community can be aware of each other's acts of courage and respond using compassion. Living in structured and affiliative-orientated communities that are guided by scientific models of affect and self-regulation offers potential therapeutic advantages over individual outpatient therapy for certain client groups. This conclusion should be investigated further. Key Practitioner Message Current therapeutic community practice is not sufficiently evidence based and may not be maximizing the potential therapeutic value of a community. Compassion-focussed therapy and social learning theory offer new approaches for a therapeutic environment, involving an understanding of the role, nature and complexities of compassionate and affiliative relationships from staff and members, behavioural change guided by

Transference in the nurse-patient relationship.

Science.gov (United States)

Evans, A M

2007-04-01

The therapeutic relationship has been considered foundational to psychiatric nursing practice since at least the mid-20th century. However, this does not, in itself, guarantee either its continuity or relevance to current practice. Concepts such as the therapeutic relationship require sustained attention, both in theory and in practice, to illustrate ongoing relevance to the discipline. This paper addresses the therapeutic relationship in psychiatric nursing via aspects of psychoanalytic theory, particularly the notion of transference, as theorized by both Freud and Lacan. Two case fragments provide practice material, through which transference in the nurse-patient relationship is explored. The nurse, in the context of his/her relationship with the patient, a sick stranger, offers both a listening and the potential development of transference. This transference can be experienced, in part, as a form of attachment to the nurse, one that is not regarded pejoratively as dependency. There is the potential, within the nurse-patient relationship, for a psychical holding to develop, one from within which both the patient can speak and transference might arise. It is argued that listening to the patient has the potential to assist the patient and, with the development of transference, can provide the context for important work.

The psychological construct of 'therapeutic alliance' can be used to better understand the effectiveness of consultations, particularly goal setting for weight management. We analysed audio-recorded health coaching sessions during a weight loss trial to explore relationships between therapeutic alliance and various contextual factors. Audio recordings of 50 health coaching sessions were analysed. After assessing fidelity to the protocol, therapeutic alliance was measured using an adapted Working Alliance Inventory Observer-rated Short Version (WAI-O-S), and examined by (i) identifying relationships between contextual factors and WAI-O-S scores (Spearman's coefficients); (ii) testing the impact of preparatory exercises and body mass index on WAI-O-S scores (one-way analysis of variance and least-squared differences tests) and (iii) comparing differences in WAI-O-S scores based on relationship status, gender and follow-up session completion (independent samples t-tests). Fidelity was high (mean 88%). WAI-O-S total scores ranged from 55 to 70 (out of 84). Session duration was significantly correlated with WAI-O-S component of 'Bond' (r = 0.42, P = 0.002). Those who completed preparatory exercises had significantly higher total WAI-O-S scores, 'Goal' and 'Task' scores. Participants who completed the follow-up session scored significantly higher for 'Goal' compared to no follow-up. Spending more time in a session appears related to increased bonding, a key component of therapeutic alliance. Preparatory work may help build therapeutic alliance and agreement on goals appears to influence follow-up completion. These exploratory findings provide directions for research addressing the professional relationship in dietetic consultations for weight loss. © 2018 Dietitians Association of Australia.

Conservation of a unique mechanism of immune evasion across the Lyssavirus genus.

The evasion of host innate immunity by Rabies virus, the prototype of the genus Lyssavirus, depends on a unique mechanism of selective targeting of interferon-activated STAT proteins by the viral phosphoprotein (P-protein). However, the immune evasion strategies of other lyssaviruses, including several lethal human pathogens, are unresolved. Here, we show that this mechanism is conserved between the most distantly related members of the genus, providing important insights into the pathogenesis and potential therapeutic targeting of lyssaviruses.

2018-06-01

Previous research has clearly demonstrated the positive impact of therapeutic interventions on offenders' well-being. Much less is known about the impact on prison staff facilitating and delivering such interventions. We employed qualitative methodology to capture a deeper understanding of the work of therapeutic prison officers. Seven prison officers working in a U.K. Category B therapeutic community prison were interviewed about their working lives, including their own participation in therapy. Following a thematic analysis approach, key findings indicated that the physical and cultural work environment was very important to staff; the therapeutic element of their job role, although demanding, was both satisfying and rewarding; and that working in a therapeutic prison environment provided the opportunity for personal as well as professional development. We conclude that further attention should be given to the unique nature of therapeutic prison work and the positive impact it can have on well-being at work.

Individual unstructured interviews were conducted with eleven younger student nurses (aged l7 years and 5 months-l8 years and 11 months) and nine young people with a chronic illness (aged 13 years and 7 months-18 years and 1 month). The data was collected in 2009. Young people in the hospital with a chronic illness experienced moments in time when they had nothing to think about but the business of getting better. During unique caring interactions, younger children's nursing students were able to help them temporarily forget about their illness and promote for them a sense of normalcy. Younger children's nursing students are in a unique position to engage in ontological caring interactions with the young people due to their similarity in age and stage of development. They are uniquely placed to help the young people reintegrate back into their known "lifeworlds" and promote for them a sense of "normalcy". Clinical staff need to be alerted to the emotional distress caused to young people during long periods of time in the hospital. Practitioners and nurse educators should be facilitating younger student nurses to interact with the young people in a therapeutic way and the care delivered to young people in the hospital should promote a sense of normalcy for them. © 2013.

The evasion of host innate immunity by Rabies virus, the prototype of the genus Lyssavirus, depends on a unique mechanism of selective targeting of interferon-activated STAT proteins by the viral phosphoprotein (P-protein). However, the immune evasion strategies of other lyssaviruses, including several lethal human pathogens, are unresolved. Here, we show that this mechanism is conserved between the most distantly related members of the genus, providing important insights into the pathogenesis and potential therapeutic targeting of lyssaviruses.

Marginalization is often presented as the strategy associated with the worst adjustment for immigrants. This study identifies a critical variable that buffers marginal immigrants from the negative effects of marginalization on adjustment: The need for uniqueness. In three studies, we surveyed immigrants recruited on university campuses (n = 119, n = 116) and in the field (n = 61). Among marginal immigrants, a higher need for uniqueness predicted higher self-esteem (Study 1), affect (Study 2), and life satisfaction (Study 3), and marginally higher happiness (Study 2) and self-esteem (Study 3). No relationship between the need for uniqueness and adjustment was found among non-marginal immigrants. The adaptive value of the need for uniqueness for marginal immigrants is discussed. © 2015 The British Psychological Society.

S Jahani

2012-01-01

Full Text Available Introduction: Despite the implementation of DOTS strategy, TB remains one of the ten leading causes of death in developing countries. Compliance with treatment is affected by social, cultural, and economic factors, and patients’ knowledge and attitude as well. The aim of this study was to determine the relationship between compliance with treatment and personal, social and therapeutic factors in TB patients in Ahwaz. Methods: This cross-sectional descriptive study was conducted on 167 TB patients. Subjects were selected based on target. The data were collected using a questionnaire, and by observation, sputum analysis, and Kvzart Ponce urine test. The validity of the questionnaire was tested by the method of content validity, and its internal consistency and reliability was tested by Cronbach's alpha coefficient. Data analyzed by SpSS. Results: Among all subjects, 52.7% of patients showed complete compliance and 35.2% and 12% of them showed partial and poor compliance, respectively. There was a significant relationship between treatment compliance and gender(p=0.009, quality of monthly income(p=0.007, and addiction(p=0.001. The quality of treatment compliance was not significantly related to age, marital status, educational level, ethnicity, and medical complications. Conclusion: The findings showed that Incomplete treatment of TB is much worse than not treating it, because the lack of precision in the administration and consumption of anti-tuberculosis drugs, leads to the emergence of resistant TB. Paying attention to the factors decreasing treatment compliance and trying to eliminate them may lead to better treatment and lower incidence and prevalence of tuberculosis in the community.

The use of lipid formulations has greatly improved the ability to effectively deliver oligonucleotides and has been instrumental in the rapid expansion of therapeutic development programs using oligonucleotide drugs. However, the development of such complex multicomponent therapeutics requires the implementation of unique, scientifically sound approaches to the nonclinical development of these drugs, based upon a hybrid of knowledge and experiences drawn from small molecule, protein, and oligonucleotide therapeutic drug development. The relative paucity of directly applicable regulatory guidance documents for oligonucleotide therapeutics in general has resulted in the generation of multiple white papers from oligonucleotide drug development experts and members of the Oligonucleotide Safety Working Group (OSWG). The members of the Formulated Oligonucleotide Subcommittee of the OSWG have utilized their collective experience working with a variety of formulations and their associated oligonucleotide payloads, as well as their insights into regulatory considerations and expectations, to generate a series of consensus recommendations for the pharmacokinetic characterization and nonclinical safety assessment of this unique class of therapeutics. It should be noted that the focus of Subcommittee discussions was on lipid nanoparticle and other types of particulate formulations of therapeutic oligonucleotides and not on conjugates or other types of modifications of oligonucleotide structure intended to facilitate delivery.

The therapeutic relationship is a critical component of psychological treatment. Strain can occur in the relationship, particularly when working with offenders, and more specifically, those offenders with interpersonal difficulties; strain can lead to a rupture, which may affect treatment participation and performance. This study examined ruptures in the therapeutic relationship in sexual offenders participating in offense-focused group treatment. Fifty-four sex offenders rated the therapeutic alliance at the commencement and completion of treatment; at the completion of treatment, they also reported on the occurrence of ruptures and whether they believed these ruptures were repaired. Ruptures were separated by type, according to severity-Each relationship was therefore characterized as experiencing no rupture, a minor rupture, or a major rupture. Offender characteristics including interpersonal style (IPS) and psychopathy were assessed at the commencement of treatment; their relationship with ruptures was examined. Results revealed that more than half of the offenders (approximately 55%) experienced a rupture in the therapeutic alliance, with one in four of these ruptures remaining unresolved. Offenders who did not report a rupture rated the therapeutic alliance significantly higher at the end of treatment compared with those offenders who reported a rupture that was not repaired. Offenders who reported a major rupture in the therapeutic relationship were higher in interpersonal hostility and hostile-dominance. No interpersonal or offense-specific factors affected the likelihood of a rupture repair.

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).

Objectives To evaluate the impact of therapeutic HIV vaccination on the HIV reservoir, and assess the relationship of the viral reservoir with HIV-specific immune status and viral rebound kinetics. Design Retrospective analysis of ACTG A5197, a randomized, placebo-controlled trial of a therapeutic rAd5 HIV-1 gag vaccine. Methods Participants received vaccine/placebo at weeks 0, 4, and 26 prior to a 16-week analytic treatment interruption (ATI) at week 38. Cell-associated HIV-1 RNA and DNA (CA-RNA and CA-DNA) and HIV-1 residual viremia (RV) were quantified at weeks 0, 8, and 38. HIV-specific CD4+/CD8+ activity were assessed by an intracellular cytokine staining assay. Results At study entry, CA-RNA and CA-DNA levels were correlated inversely with the numbers of HIV-specific CD4+ interferon-γ-producing cells (CA-RNA: r = −0.23, P=0.03 and CA-DNA: r = −0.28, P<0.01, N=93). Therapeutic HIV vaccination induced HIV-specific CD4+ activity, but did not significantly affect levels of CA-RNA or CA-DNA. Vaccine recipients with undetectable RV at week 8 had higher frequencies of HIV-specific CD4+ and CD8+ interferon-γ-producing cells (undetectable versus detectable RV: 277 versus 161 CD4+ cells/106 lymphocytes, P=0.03 and 1326 versus 669 CD8+ cells/106 lymphocytes, P=0.04). Pre-ATI CA-RNA and CA-DNA were associated with post-ATI plasma HIV set point (CA-RNA: r = 0.51, P<0.01 and CA-DNA: r = 0.47, P<0.01). Conclusions Vaccine-induced T-cell responses were associated with a modest transient effect on RV, but more potent immune responses and/or combination treatment with latency-reversing agents are needed to reduce the HIV reservoir. HIV reservoir measures may act as biomarkers of post-ATI viral rebound kinetics. PMID:25254301

2014-09-01

Full Text Available In this review, several glycosaminoglycan analogs obtained from different marine invertebrate are reported. The structure, biological activity and mechanism of action of these unique molecules are detailed reviewed and exemplified by experiments in vitro and in vivo. Among the glycans studied are low-sulfated heparin-like polymers from ascidians, containing significant anticoagulant activity and no bleeding effect; dermatan sulfates with significant neurite outgrowth promoting activity and anti-P-selectin from ascidians, and a unique fucosylated chondroitin sulfate from sea cucumbers, possessing anticoagulant activity after oral administration and high anti P- and L-selectin activities. The therapeutic value and safety of these invertebrate glycans have been extensively proved by several experimental animal models of diseases, including thrombosis, inflammation and metastasis. These invertebrate glycans can be obtained in high concentrations from marine organisms that have been used as a food source for decades, and usually obtained from marine farms in sufficient quantities to be used as starting material for new therapeutics.

2013-03-01

In this article, the very recent progress of various functional inorganic nanomaterials is reviewed including their unique properties, surface functionalization strategies, and applications in biosensing and imaging-guided therapeutics. The proper surface functionalization renders them with stability, biocompatibility and functionality in physiological environments, and further enables their targeted use in bioapplications after bioconjugation via selective and specific recognition. The surface-functionalized nanoprobes using the most actively studied nanoparticles (i.e., gold nanoparticles, quantum dots, upconversion nanoparticles, and magnetic nanoparticles) make them an excellent platform for a wide range of bioapplications. With more efforts in recent years, they have been widely developed as labeling probes to detect various biological species such as proteins, nucleic acids and ions, and extensively employed as imaging probes to guide therapeutics such as drug/gene delivery and photothermal/photodynamic therapy.

The third therapeutic system: faith healing strategies in the context of a generalized AIDS epidemic.

Manglos, Nicolette D; Trinitapoli, Jenny

2011-03-01

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.

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.

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

Megan Leander

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

• Transsexual persons are increasing their visibility in society, and health care providers and others (such as social workers) will be called upon to help with issues that transsexual persons face. Challenges that face transsexual persons often include issues involving relationships. Psychiatric and mental health nurses and other caregivers can increase their therapeutic skills in working with couples that include transsexual persons by becoming aware of these challenges and subsequent activities that can help with them. • This research study looks at couple relationships in which one partner reveals male-to-female transsexual identity. These are relationships that were established as man-woman and now will transition into relationships that include a male-to-female person and a female partner. • Common challenges for these couples include issues related to: (1) sexual identity and relationship uncertainty; (2) male-to-female transition decision making; and (3) presenting in public. • Relationship maintenance activities that helped the couples in the study maintain and strengthen their relationships through these challenges include: (1) communication; (2) self-talk (for example, putting the situation in perspective); (3) social networks; (4) positive interactions; (5) impression management (for example, managing displays of affection in public); and (6) social activism. This qualitative study describes the relational dynamics that help sustain relationships of couples that include male-to-female transsexual persons (MTF) and their natal female partners (NF) following disclosure of transsexualism. Relationship challenges and relationship maintenance activities are identified. Each partner in 17 MTF-NF couples participated in individual surveys and interviews. The data were coded for themes related to relationship challenges and activities. MTF-NF couples experience challenges within the contexts of their relationships and of society. These challenges

Social stress resulting from stigma, prejudice, and discrimination-"minority stress"-negatively impacts sexual minority individuals' health and relational well-being. The present study examined how being in a same-sex couple can result in exposure to unique minority stressors not accounted for at the individual level. Relationship timeline interviews were conducted with 120 same-sex couples equally distributed across two study sites (Atlanta and San Francisco), gender (male and female), and relationship duration (at least six months but less than three years, at least three years but less than seven years, and seven or more years). Directed content analyses identified 17 unique couple-level minority stressors experienced within nine distinct social contexts. Analyses also revealed experiences of dyadic minority stress processes (stress discrepancies and stress contagion). These findings can be useful in future efforts to better understand and address the cumulative impact of minority stress on relational well-being and individual health.

A Practice-Based Theory of Healing Through Therapeutic Touch: Advancing Holistic Nursing Practice.

Hanley, Mary Anne; Coppa, Denise; Shields, Deborah

2017-08-01

For nearly 50 years, Therapeutic Touch (TT) has contributed to advancing holistic nursing practice and has been recognized as a uniquely human approach to healing. This narrative explores the development of a practice-based theory of healing through TT, which occurred between 2010 and 2016. Through the in-depth self-inquiry of participatory reflective dialogue in concert with constant narrative analysis, TT practitioners revealed the meaning of healing within the context of their TT practice. As the community of TT experts participated in an iterative process of small group and community dialogues with analysis and synthesis of emerging themes, the assumptions and concepts central to a theory of healing emerged, were clarified and verified. Exemplars of practice illustrate the concepts. A model of the theory of healing illuminates the movement and relationship among concepts and evolved over time. Feedback from nursing and inter-professional practitioners indicate that the theory of healing, while situated within the context of TT, may be useful in advancing holistic nursing practice, informing healing and caring approaches, stimulating research and education, and contributing to future transformations in health care.

Peer support programmes use individuals with specific experiences to improve engagement and outcomes among new clients. However, the skills and techniques used to achieve this engagement have not been mapped. This potentially restricts the development and replication of successful peer advocate models of care. This study explored how a group of peer advocates with experience of homelessness, alcohol and drug misuse made and sustained relationships with their client group. For the purposes of this project, the client group were located among a hepatitis C-positive cohort of people who have a history of injecting drug use and homelessness. Five self-selecting advocates gave a narrative interview lasting 40-90 min. These interviews were double transcribed using both thematic analysis and narrative analysis in order to triangulate the data and provide a robust set of findings about the unique skills of peer advocates in creating and sustaining relationships with clients from hard-to-reach populations. Peer advocates build rapport with clients through disclosing personal details about their lives. While this runs counter to assumptions about the need to maintain distance in client-patient relationships, the therapeutic benefits appear to outweigh the potential costs of this engagement. We conclude the therapeutic benefits of self-disclosure between peer advocates and their clients offer a moral grounding for self-disclosure as a means of building relationships with key hard-to-reach populations.

Neurosteroids in Schizophrenia: Pathogenic and Therapeutic Implications

HuaLin Cai

2018-03-01

Full Text Available Neurosteroids are a group of important endogenous molecules affecting many neural functions in the brain. Increasing evidence suggests a possible role of these neurosteroids in the pathology and symptomatology of schizophrenia (SZ and other mental disorders. The aim of this review is to summarize the current knowledge about the neural functions of neurosteroids in the brain, and to evaluate the role of the key neurosteroids as candidate modulators in the etiology and therapeutics of SZ. The present paper provides a brief introduction of neurosteroid metabolism and distribution, followed by a discussion of the mechanisms underlying neurosteroid actions in the brain. The content regarding the modulation of the GABAA receptor is elaborated, given the considerable knowledge of its interactions with other neurotransmitter and neuroprotective systems, as well as its ameliorating effects on stress that may play a role in the SZ pathophysiology. In addition, several preclinical and clinical studies suggested a therapeutic benefit of neurosteroids in SZ patients, even though the presence of altered neurosteroid pathways in the circulating blood and/or brain remains debatable. Following treatment of antipsychotic drugs in SZ, therapeutic benefits have also been linked to the regulation of neurosteroid signaling. Specifically, the neurosteroids such as pregnenolone and dehydroepiandrosterone affect a broad spectrum of behavioral functions through their unique molecular characteristics and may represent innovative therapeutic targets for SZ. Future investigations in larger cohorts with long-term follow-ups will be required to ascertain the neuropsychopharmacological role of this yet unexploited class of neurosteroid agents.

Full Text Available This qualitative scientific study – by means of analysing recorded therapeutic sessions with children with autism or mental disability in a special school – examines the process of creating a relationship between the therapist and the child in the context of music-therapeutic moments. The analysis of therapeutic moments was carried out through the AQR-instrument (Assessment of the Quality of Relationship and led to a the evaluation of the quality of relationship between the therapist and the child with autism or mental disability during therapy, b the evaluation of the correspondence of the therapeutic intervention to each child’s developmental level (modus, and c the appreciation of the differentiation in the relationship between the therapist and the child with autism or mental disability, as well as the size of that differentiation. Regardless of the pathology, it was observed that music therapy with children is advisable when the child shows disorders in his/her emotional development and in the ability to create a relationship. Music-therapeutic interventions that use the child itself as a starting point and follow the concept of elemental music, succeed in mobilising children’s healthy part and promote their development, in many areas. Research data are based on the author’s dissertation thesis: “Music therapy for children with psychological disorders in special education” (Fragkouli 2012.

Full Text Available In nanomedicine, targeted therapeutic nanoparticle (NP is a virtual outcome of nanotechnology taking the advantage of cancer propagation pattern. Tying up all elements such as therapeutic or imaging agent, targeting ligand, and cross-linking agent with the NPs is the key concept to deliver the payload selectively where it intends to reach. The microenvironment of tumor tissues in lymphatic vessels can also help targeted NPs to achieve their anticipated accumulation depending on the formulation objectives. This review accumulates the application of poly(lactic-co-glycolic acid (PLGA and polyethylene glycol (PEG based NP systems, with a specific perspective in cancer. Nowadays, PLGA, PEG, or their combinations are the mostly used polymers to serve the purpose of targeted therapeutic NPs. Their unique physicochemical properties along with their biological activities are also discussed. Depending on the biological effects from parameters associated with existing NPs, several advantages and limitations have been explored in teaming up all the essential facts to give birth to targeted therapeutic NPs. Therefore, the current article will provide a comprehensive review of various approaches to fabricate a targeted system to achieve appropriate physicochemical properties. Based on such findings, researchers can realize the benefits and challenges for the next generation of delivery systems.

2008-04-01

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.

Proteins are effective biotherapeutics with applications in diverse ailments. Despite being specific and potent, their full clinical potential has not yet been realized. This can be attributed to short half-lives, complex structures, poor in vivo stability, low permeability, frequent parenteral administrations and poor adherence to treatment in chronic diseases. A sustained release system, providing controlled release of proteins, may overcome many of these limitations. This review focuses on recent development in approaches, especially polymer-based formulations, which can provide therapeutic levels of proteins over extended periods. Advances in particulate, gel-based formulations and novel approaches for extended protein delivery are discussed. Emphasis is placed on dosage form, method of preparation, mechanism of release and stability of biotherapeutics. Substantial advancements have been made in the field of extended protein delivery via various polymer-based formulations over last decade despite the unique delivery-related challenges posed by protein biologics. A number of injectable sustained-release formulations have reached market. However, therapeutic application of proteins is still hampered by delivery-related issues. A large number of protein molecules are under clinical trials, and hence, there is an urgent need to develop new methods to deliver these highly potent biologics.

Full Text Available Science always strives to find an improved way of doing things and nanoscience is one such approach. Nanomaterials are suitable for pharmaceutical applications mostly because of their size which facilitates absorption, distribution, metabolism and excretion of the nanoparticles. Whether labile or insoluble nanoparticles, their cytotoxic effect on malignant cells has moved the use of nanomedicine into focus. Since nanomedicine can be described as the science and technology of diagnosing, treating and preventing diseases towards ultimately improving human health, a lot of nanotechnology options have received approval by various regulatory agencies. Nanodrugs also have been discovered to be more precise in targeting the desired site, hence maximizing the therapeutic effects, while minimizing side-effects on the rest of the body. This unique property and more has made nanomedicine popular in therapeutic medicine employing nanotechnology in genetic therapy, drug encapsulation, enzyme manipulation and control, tissue engineering, target drug delivery, pharmacogenomics, stem cell and cloning, and even virus-based hybrids. This review highlights nanoproducts that are in development and have gained approval through one clinical trial stage or the other.

2016-02-01

Botulinum neurotoxin (BoNT) produced by Clostridium botulinum is the most potent molecule known to mankind. Higher potency of BoNT is attributed to several factors, including structural and functional uniqueness, target specificity, and longevity. Although BoNT is an extremely toxic molecule, it is now increasingly used for the treatment of disorders related to muscle hyperactivity and glandular hyperactivity. Weakening of muscles due to peripheral action of BoNT produces a therapeutic effect. Depending on the target tissue, BoNT can block the cholinergic neuromuscular or cholinergic autonomic innervation of exocrine glands and smooth muscles. In recent observations of the analgesic properties of BoNT, the toxin modifies the sensory feedback loop to the central nervous system. Differential effects of BoNT in excitatory and inhibitory neurons provide a unique therapeutic tool. In this review the authors briefly summarize the structure and mechanism of actions of BoNT on motor and sensory neurons to explain its therapeutic effects and future potential.

Crosstalk between Apoptosis and Autophagy: Molecular Mechanisms and Therapeutic Strategies in Cancer

2013-01-01

Full Text Available Both apoptosis and autophagy are highly conserved processes that besides their role in the maintenance of the organismal and cellular homeostasis serve as a main target of tumor therapeutics. Although their important roles in the modulation of tumor therapeutic strategies have been widely reported, the molecular actions of both apoptosis and autophagy are counteracted by cancer protective mechanisms. While apoptosis is a tightly regulated process that is implicated in the removal of damaged or unwanted cells, autophagy is a cellular catabolic pathway that is involved in lysosomal degradation and recycling of proteins and organelles, and thereby is considered an important survival/protective mechanism for cancer cells in response to metabolic stress or chemotherapy. Although the relationship between autophagy and cell death is very complicated and has not been characterized in detail, the molecular mechanisms that control this relationship are considered to be a relevant target for the development of a therapeutic strategy for tumor treatment. In this review, we focus on the molecular mechanisms of apoptosis, autophagy, and those of the crosstalk between apoptosis and autophagy in order to provide insight into the molecular mechanisms that may be essential for the balance between cell survival and death as well as their role as targets for the development of novel therapeutic approaches.

Uniqueness and non-uniqueness of semigroups generated by singular diffusion operators

CERN Document Server

Eberle, Andreas

1999-01-01

This book addresses both probabilists working on diffusion processes and analysts interested in linear parabolic partial differential equations with singular coefficients. The central question discussed is whether a given diffusion operator, i.e., a second order linear differential operator without zeroth order term, which is a priori defined on test functions over some (finite or infinite dimensional) state space only, uniquely determines a strongly continuous semigroup on a corresponding weighted Lp space. Particular emphasis is placed on phenomena causing non-uniqueness, as well as on the relation between different notions of uniqueness appearing in analytic and probabilistic contexts.

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.

Therapist self-disclosure and the therapeutic alliance in the treatment of eating problems.

Simonds, Laura M; Spokes, Naomi

2017-01-01

Evidence is mixed regarding the potential utility of therapist self-disclosure. The current study modelled relationships between perceived helpfulness of therapist self-disclosures, therapeutic alliance, patient non-disclosure, and shame in participants (n = 120; 95% women) with a history of eating problems. Serial multiple mediator analyses provided support for a putative model connecting the perceived helpfulness of therapist self-disclosures with current eating disorder symptom severity through therapeutic alliance, patient self-disclosure, and shame. The analyses presented provide support for the contention that therapist self-disclosure, if perceived as helpful, might strengthen the therapeutic alliance. A strong therapeutic alliance, in turn, has the potential to promote patient disclosure and reduce shame and eating problems.

Tools for predicting the PK/PD of therapeutic proteins.

Diao, Lei; Meibohm, Bernd

2015-07-01

Assessments of the pharmacokinetic/pharmacodynamic (PK/PD) characteristics are an integral part in the development of novel therapeutic agents. Compared with traditional small molecule drugs, therapeutic proteins possess many distinct PK/PD features that necessitate the application of modified or separate approaches for assessing their PK/PD relationships. In this review, the authors discuss tools that are utilized to describe and predict the PK/PD features of therapeutic proteins and that are valuable additions in the armamentarium of drug development approaches to facilitate and accelerate their successful preclinical and clinical development. A variety of state-of-the-art PK/PD tools is currently being applied and has been adjusted to support the development of proteins as therapeutics, including allometric scaling approaches, target-mediated disposition models, first-in-man dose calculations, physiologically based PK models and empirical and semi-mechanistic PK/PD modeling. With the advent of the next generation of biologics including bioengineered antibody constructs being developed, these tools will need to be further refined and adapted to ensure their applicability and successful facilitation of the drug development process for these novel scaffolds.

[Uniqueness seeking behavior as a self-verification: an alternative approach to the study of uniqueness].

Science.gov (United States)

Yamaoka, S

1995-06-01

Uniqueness theory explains that extremely high perceived similarity between self and others evokes negative emotional reactions and causes uniqueness seeking behavior. However, the theory conceptualizes similarity so ambiguously that it appears to suffer from low predictive validity. The purpose of the current article is to propose an alternative explanation of uniqueness seeking behavior. It posits that perceived uniqueness deprivation is a threat to self-concepts, and therefore causes self-verification behavior. Two levels of self verification are conceived: one based on personal categorization and the other on social categorization. The present approach regards uniqueness seeking behavior as the personal-level self verification. To test these propositions, a 2 (very high or moderate similarity information) x 2 (with or without outgroup information) x 2 (high or low need for uniqueness) between-subject factorial-design experiment was conducted with 95 university students. Results supported the self-verification approach, and were discussed in terms of effects of uniqueness deprivation, levels of self-categorization, and individual differences in need for uniqueness.

Spherical Nucleic Acids as Intracellular Agents for Nucleic Acid Based Therapeutics

Science.gov (United States)

Hao, Liangliang

Recent functional discoveries on the noncoding sequences of human genome and transcriptome could lead to revolutionary treatment modalities because the noncoding RNAs (ncRNAs) can be applied as therapeutic agents to manipulate disease-causing genes. To date few nucleic acid-based therapeutics have been translated into the clinic due to challenges in the delivery of the oligonucleotide agents in an effective, cell specific, and non-toxic fashion. Unmodified oligonucleotide agents are destroyed rapidly in biological fluids by enzymatic degradation and have difficulty crossing the plasma membrane without the aid of transfection reagents, which often cause inflammatory, cytotoxic, or immunogenic side effects. Spherical nucleic acids (SNAs), nanoparticles consisting of densely organized and highly oriented oligonucleotides, pose one possible solution to circumventing these problems in both the antisense and RNA interference (RNAi) pathways. The unique three dimensional architecture of SNAs protects the bioactive oligonucleotides from unspecific degradation during delivery and supports their targeting of class A scavenger receptors and endocytosis via a lipid-raft-dependent, caveolae-mediated pathway. Owing to their unique structure, SNAs are able to cross cell membranes and regulate target genes expression as a single entity, without triggering the cellular innate immune response. Herein, my thesis has focused on understanding the interactions between SNAs and cellular components and developing SNA-based nanostructures to improve therapeutic capabilities. Specifically, I developed a novel SNA-based, nanoscale agent for delivery of therapeutic oligonucleotides to manipulate microRNAs (miRNAs), the endogenous post-transcriptional gene regulators. I investigated the role of SNAs involving miRNAs in anti-cancer or anti-inflammation responses in cells and in in vivo murine disease models via systemic injection. Furthermore, I explored using different strategies to construct

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.

Attitude Certainty and Attitudinal Advocacy: The Unique Roles of Clarity and Correctness.

Science.gov (United States)

Cheatham, Lauren; Tormala, Zakary L

2015-11-01

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. © 2015 by the Society for Personality and Social Psychology, Inc.

Electroconvulsive therapy-induced brain plasticity determines therapeutic outcome in mood disorders

Dukart, Juergen; Regen, Francesca; Kherif, Ferath; Colla, Michael; Bajbouj, Malek; Heuser, Isabella; Frackowiak, Richard S.; Draganski, Bogdan

2014-01-01

There remains much scientific, clinical, and ethical controversy concerning the use of electroconvulsive therapy (ECT) for psychiatric disorders stemming from a lack of information and knowledge about how such treatment might work, given its nonspecific and spatially unfocused nature. The mode of action of ECT has even been ascribed to a “barbaric” form of placebo effect. Here we show differential, highly specific, spatially distributed effects of ECT on regional brain structure in two populations: patients with unipolar or bipolar disorder. Unipolar and bipolar disorders respond differentially to ECT and the associated local brain-volume changes, which occur in areas previously associated with these diseases, correlate with symptom severity and the therapeutic effect. Our unique evidence shows that electrophysical therapeutic effects, although applied generally, take on regional significance through interactions with brain pathophysiology. PMID:24379394

This study investigated the relationship between work-related variables and perceived levels of burnout of therapeutic recreation personnel who work with long-term psychiatric patients in Veterans Administration hospitals. Subjects completed a three-part instrument composed of a demographic questionnaire, the Maslach Burnout Inventory and the Work Environment Scale. Of the 511 subjects surveyed, 287 (56%) responded with usable questionnaires. The demographic, job- and profession-related variables were found to be significantly related to burnout. The eta values were somewhat low. The WES variables accounted for 20.9% of the variance in the burnout measures. The WES variables accounted for 20.9% of the variance in the burnout measures. The most salient relationships emerged between the emotional exhaustion and the depersonalization subscales and clarity, supervisor support, involvement, work pressure, autonomy, innovation, peer cohesion, task orientation and physical comfort. In comparison with other groups of human service professionals, therapeutic recreation personnel experienced low levels of emotional exhaustion, moderate levels of depersonalization, and somewhat lower levels of personal accomplishment.

Lu, Victor M; McDonald, Kerrie L; Townley, Helen E

2017-10-01

The prognosis of brain cancer glioblastoma (GBM) is poor, and despite intense research, there have been no significant improvements within the last decade. This stasis implicates the need for more novel therapeutic investigation. One such option is the use of nanoparticles (NPs), which can be beneficial due to their ability to penetrate the brain, overcome the blood-brain barrier and take advantage of the enhanced permeation and retention effect of GBM to improve specificity. Rare earth elements possess a number of interesting natural properties due to their unique electronic configuration, which may prove therapeutically advantageous in an NP formulation. The underexplored exciting potential for rare earth elements to augment the therapeutic potential of NPs in GBM treatment is discussed in this review.

2011-10-01

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.

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

2017-05-01

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.

Relationship between potential aggregation-prone regions and HLA-DR-binding T-cell immune epitopes: implications for rational design of novel and follow-on therapeutic antibodies.

Kumar, Sandeep; Mitchell, Mark A; Rup, Bonita; Singh, Satish K

2012-08-01

Aggregation and unwanted immunogenicity are hurdles to avoid in successful commercial development of antibody-based therapeutics. In this article, the relationship between aggregation-prone regions (APRs), capable of forming cross-β motifs/amyloid fibrils, and major histocompatibility complex class II-restricted human leukocyte antigen (HLA)-DR-binding T-cell immune epitopes (TcIEs) is analyzed using amino acid sequences of 25 therapeutic antibodies, 55 TcIEs recognized by T-regulatory cells (tregitopes), 1000 randomly generated 15-residue-long peptides, 2257 human self-TcIEs (autoantigens), and 11 peptides in HLA-peptide cocrystal structures. Sequence analyses from these diverse sources consistently show a high level of correlation between APRs and TcIEs: approximately one-third of TcIEs contain APRs, but the majority of APRs occur within TcIE regions (TcIERs). Tregitopes also contain APRs. Most APR-containing TcIERs can bind multiple HLA-DR alleles, suggesting that aggregation-driven adverse immune responses could impact a broad segment of patient population. This article has identified common molecular sequence-structure loci that potentially contribute toward both manufacturability and safety profiles of the therapeutic antibodies, thereby laying a foundation for simultaneous optimization of these attributes in novel and follow-on candidates. Incidence of APRs within TcIERs is not special to biotherapeutics, self-TcIEs from human proteins, involved in various diseases, also contain predicted APRs and experimentally proven amyloid-fibril-forming peptide sequence portions.

Although representative payeeship provided within clinical settings is believed to have therapeutic benefits, its potential negative impact on the therapeutic alliance or client-provider relationship is of concern. This study examined the effects of payeeship and perceived financial leverage on positive and negative dimensions of the client-provider relationship. The sample consisted of 205 adults ages 18 to 65 with axis I disorders who were receiving mental health services from a large urban community mental health clinic. Information about money management characteristics and ratings of the client-provider relationship were collected via face-to-face interview. Fifty-three percent of the sample had a payee or money manager, and 79% of this group had a clinician payee. Respondents with co-occurring psychotic and substance use disorders, lower functioning, and lower insight about their illness were more likely to have a clinician payee. Forty percent of those with a clinician payee reported perceived financial leverage. Having a clinician payee was also associated with perceived financial leverage and with higher levels of conflict in the case management relationship. When examined in combination, financial leverage was found to mediate the effects of payeeship on conflict in the case management relationship (mean+/-SE=2.37+/-1.33, 95% confidence interval=16-5.52, pconflict in the therapeutic alliance when used as a source of treatment leverage. Although payeeship provides important support and may enhance functional outcomes for the patient, decisions about using the mechanism for promoting treatment adherence should take into account the potential disruption to the client-provider relationship.

Therapeutic Approaches to Histone Reprogramming in Retinal Degeneration.

Science.gov (United States)

Berner, Andre K; Kleinman, Mark E

2016-01-01

Recent data have revealed epigenetic derangements and subsequent chromatin remodeling as a potent biologic switch for chronic inflammation and cell survival which are important therapeutic targets in the pathogenesis of several retinal degenerations. Histone deacetylases (HDACs) are a major component of this system and serve as a unique control of the chromatin remodeling process. With a multitude of targeted HDAC inhibitors now available, their use in both basic science and clinical studies has widened substantially. In the field of ocular biology, there are data to suggest that HDAC inhibition may suppress neovascularization and may be a possible treatment for retinitis pigmentosa and dry age-related macular degeneration (AMD). However, the effects of these inhibitors on cell survival and chemokine expression in the chorioretinal tissues remain very unclear. Here, we review the multifaceted biology of HDAC activity and pharmacologic inhibition while offering further insight into the importance of this epigenetic pathway in retinal degenerations. Our laboratory investigations aim to open translational avenues to advance dry AMD therapeutics while exploring the role of acetylation on inflammatory gene expression in the aging and degenerating retina.

Male emotional intimacy: how therapeutic men's groups can enhance couples therapy.

Science.gov (United States)

Garfield, Robert

2010-03-01

Men's difficulty with emotional intimacy is a problem that therapists regularly encounter in working with heterosexual couples in therapy. The first part of this article describes historical and cultural factors that contribute to this dilemma in men's marriages and same-sex friendships. Therapeutic men's groups can provide a corrective experience for men, helping them to develop emotional intimacy skills while augmenting their work in couples therapy. A model for such groups is presented, including guidelines for referral, screening, and collaboration with other therapists. Our therapeutic approach encourages relationship-based learning through direct emotional expression and supportive feedback. We emphasize the development of friendship skills, core attributes of friendship (connection, communication, commitment, and cooperation) that contribute to emotional intimacy in men's relationships. Case examples are included to illustrate how this model works in clinical practice, as well as specific suggestions for further study that could lead to a more evidence-based practice.

Shaping effective communication skills and therapeutic relationships at work: the foundation of collaboration.

Science.gov (United States)

Grover, Susan M

2005-04-01

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.

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.

Pharmacological considerations for predicting PK/PD at the site of action for therapeutic proteins.

Science.gov (United States)

Wang, Weirong; Zhou, Honghui

For therapeutic proteins whose sites of action are distal to the systemic circulation, both drug and target concentrations at the tissue sites are not necessarily proportional to those in systemic circulation, highlighting the importance of understanding pharmacokinetic/pharmacodynamic (PK/PD) relationship at the sites of action. This review summarizes the pharmacological considerations for predicting local PK/PD and the importance of measuring PK and PD at site of action. Three case examples are presented to show how mechanistic and physiologically based PK/PD (PBPK/PD) models which incorporated the PK and PD at the tissue site can be used to facilitate understanding the exposure-response relationship for therapeutic proteins.

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.

Science.gov (United States)

Riggs, Samantha; Cook, Carrie L

2015-09-01

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. © The Author(s) 2014.

The relationships between the CT findings following radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) and the clinical symptoms and laboratory data were examined. The subjects consisted of 31 cases (41 nodules) of HCC that were treated by RFA. The CT findings before and after RFA, particularly the findings in areas other than the treatment site (henceforth, secondary findings), were evaluated by a physician and a radiologist. In addition, the relationships between the CT findings and post-RFA clinical symptoms (fever/pain) and laboratory data were examined. Secondary findings were found in 90.3% (28/31). These findings were broadly classified into changes in the needle tract 51.6% (16/31), retention of effusion 41.9% (13/31), thickening of the gallbladder wall 12.9% (4/31), changes in the retroperitoneal space 9.7% (3/31), and dilatation of the intrahepatic bile duct 3.2% (1/31), in the order of frequency. A relationship was found between changes in the retroperitoneal space and the clinical symptoms (fever: p=0.0366, pain: p=0.0012). Relationships were also found between changes in the needle tract and retention of effusion and aspartate aminotransferase (AST) (p<0.0001), as well as between changes in the needle tract and alanine aminotransferase (ALT) (p=0.0149). The size of the treatment area did not correlate with the presence of clinical symptoms and changes in laboratory data. Diverse classification of CT findings was observed after RFA, and a relationship with clinical symptoms was noted. A relationship was also found between classification of the CT findings following RFA and the post-therapeutic outcome. (authors)

Internalization, separation-individuation, and the nature of therapeutic action.

Blatt, S J; Behrends, R S

Based on the assumption that the mutative factors that facilitate growth in psychoanalysis involve the same fundamental mechanisms that lead to psychological growth in normal development, this paper considers the constant oscillation between gratification and deprivation leading to internalization as the central therapeutic mechanism of the psychoanalytic process. Patients experience the analytic process as a series of gratifying involvements and experienced incompatibilities that facilitate internalization, whereby the patient recovers lost or disrupted regulatory, gratifying interactions with the analyst, which are real or fantasied, by appropriating these interactions, transforming them into their own, enduring, self-generated functions and characteristics. Patients internalize not only the analyst's interpretive activity, but also the analyst's sensitivity, compassion and acceptance, and, in addition, their own activity in relation to the analyst such as free association. Both interpretation and the therapeutic relationship can contain elements of gratifying involvement and experienced incompatibility that lead to internalization and therefore both can be mutative factors in the therapeutic process.

Vaccine-associated sarcomas in cats: a unique cancer model.

McNiel, E A

2001-01-01

Epidemiologic evidence supports a relationship between vaccination of cats for rabies and feline leukemia virus with the development of soft tissue sarcomas at the site of administration. These tumors are locally invasive and histologically aggressive. As with high-grade soft tissue sarcoma in humans, combination treatment with radiation therapy and surgery provides for optimum tumor control. Feline vaccine-associated sarcoma has become a difficult issue for the veterinary profession for legal, ethical, and clinical reasons. Although most research efforts have focused on therapeutic intervention, this tumor has great potential to provide an informative model for carcinogenesis and genetic susceptibility applicable to cancer in all species, including humans.

Immunogenicity to therapeutic proteins: impact on PK/PD and efficacy.

Chirmule, Narendra; Jawa, Vibha; Meibohm, Bernd

2012-06-01

The development of therapeutic proteins requires the understanding of the relationship between the dose, exposure, efficacy, and toxicity of these molecules. Several intrinsic and extrinsic factors contribute to the challenges for measuring therapeutic proteins in a precise and accurate manner. In addition, induction of an immune response to therapeutic protein results in additional complexities in the analysis of the pharmacokinetic profile, toxicity, safety, and efficacy of this class of molecules. Assessment of immunogenicity of therapeutic proteins is a required aspect of regulatory filings for a licensing application and for the safe and efficacious use of these compounds. A systematic strategy and well-defined criteria for measuring anti-drug antibodies (ADA) have been established, to a large extent, through coordinated efforts. These recommendations are based on risk assessment and include the determination of ADA content (concentration/titer), affinity, immunoglobulin isotype/subtype, and neutralization capacity. This manuscript reviews the requirements necessary for understanding the nature of an ADA response in order to discern the impact of immunogenicity on pharmacokinetics/pharmacodynamics and efficacy.

Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma. Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses. In order to identify potential subtypes, two pathologists independen...

Uniquely Strongly Clean Group Rings

A ring R is called clean if every element is the sum of an idempotent and a unit,and R is called uniquely strongly clean (USC for short) if every element is uniquely the sum of an idempotent and a unit that commute.In this article,some conditions on a ring R and a group G such that RG is clean are given.It is also shown that if G is a locally finite group,then the group ring RG is USC if and only if R is USC,and G is a 2-group.The left uniquely exchange group ring,as a middle ring of the uniquely clean ring and the USC ring,does not possess this property,and so does the uniquely exchange group ring.

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 exam...

Banerjee, Subhamoy; Ghosh, Siddhartha Sankar; Sahoo, Amaresh Kumar; Chattopadhyay, Arun

2014-01-01

The field of recombinant protein therapeutics has been evolving rapidly, making significant impact on clinical applications for several diseases, including cancer. However, the functional aspects of proteins rely exclusively on their structural integrity, in which nanoparticle mediated delivery offers unique advantages over free proteins. In the present work, a novel strategy has been developed where the nanoparticles (NPs) used for the delivery of the recombinant protein could contribute to enhancing the therapeutic efficacy of the recombinant protein. The transcription factor, NFκB, involved in cell growth and its inhibitor, IκBα, regulates its proliferation. Another similar naturally available molecule, which inhibits the function of NFκB, is curcumin. Hence, we have developed a ‘green synthesis’ method for preparing water-soluble curcumin nanoparticles to stabilize recombinant IκBα protein. The NPs were characterized by UV–vis and fluorescence spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering before administration into human cervical carcinoma (HeLa) and glioblastoma (U87MG) cells. Experimental results demonstrated that this combined module had enhanced therapeutic efficacy, causing apoptotic cell death, which was confirmed by cytotoxicity assay and flowcytometry analyses. The expression of apoptotic genes studied by semi-quantitative reverse transcription PCR delineated the molecular pathways involved in cell death. Thus, our study revealed that the functional delivery of recombinant IκBα-loaded curcumin NPs has promise as a natural-product-based protein therapeutics against cancer cells. (paper)

Regulatory roles and therapeutic potential of microRNA in sarcoma.

Science.gov (United States)

Lim, Hui Jun; Yang, Jia-Lin

2016-01-01

MicroRNAs (miRNAs) are single-stranded noncoding RNAs involved in various biological processes, including cell differentiation and development. They play multiple key roles as tumour suppressors, oncogenes or both in particular cases. This review aims to summarise current findings of the expression of miRNAs and their role in clinical oncology. Current knowledge regarding the involvement of miRNAs in different sarcoma subtypes will be assessed, in conjunction with their potential application as therapeutic targets. Relevant articles in scientific databases were identified using a combination of search terms, including "microRNA," "deregulation," "sarcoma," and "targeted therapy". These databases included Medline, Embase, Cochrane Review, Pubmed and Scopus. Aberrant miRNA expression patterns have been identified in a range of sarcoma subtypes, and differences in miRNA expression profiles between malignant cells and their normal counterparts suggests that miRNAs play key roles in sarcoma development. The identification of unique miRNA patterns in individual tumour types could possibly be used as a diagnostic tool in sarcoma. Moreover, identification of these miRNAs provides novel targets for the development of therapeutic strategies in distinct sarcoma subtypes. miRNAs hold significant potential as diagnostic biomarkers, as well as therapeutic targets in sarcoma. Possible future clinical applications include the use of miRNA pathways as therapeutic targets or miRNA expression profiling as a means of patient selection. The involvement miRNAs will undoubtedly contribute to the advancement of future targeted therapeutic interventions in sarcoma, and further establishment of appropriate delivery systems is vital for their use in clinical settings.

Therapeutic potential of gel-based injectables for vocal fold regeneration

Bartlett, Rebecca S.; Thibeault, Susan L.; Prestwich, Glenn D.

2012-01-01

Vocal folds are anatomically and biomechanically unique, thus complicating the design and implementation of tissue engineering strategies for repair and regeneration. Integration of an enhanced understanding of tissue biomechanics, wound healing dynamics and innovative gel-based therapeutics has generated enthusiasm for the notion that an efficacious treatment for vocal fold scarring could be clinically attainable within several years. Fibroblast phenotype and gene expression are mediated by the three-dimensional mechanical and chemical microenvironment at an injury site. Thus, therapeutic approaches need to coordinate spatial and temporal aspects of the wound healing response in an injured vocal tissue to achieve an optimal clinical outcome. Successful gel-based injectables for vocal fold scarring will require a keen understanding of how the native inflammatory response sets into motion the later extracellular matrix remodeling, which in turn will determine the ultimate biomechanical properties of the tissue. We present an overview of the challenges associated with this translation as well as the proposed gel-based injectable solutions. PMID:22456756

This study helped to get to know the structure of everyday life experienced by the residents, identifying some difficulties they face and the mechanisms used to overcome them, in addition to noticing that the professionals can be instrumental in strengthening a daily living that can be pluralized, busy, and enriched, while still respecting the uniqueness of each resident. doi: 10.5216/ree.v16i4.22923.

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

Science.gov (United States)

Holm-Hadulla, Rainer M

2013-01-01

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

Unmanned Aerial Vehicles unique cost estimating requirements

Science.gov (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.

Processing the Order of Symbolic Numbers: A Reliable and Unique Predictor of Arithmetic Fluency

Directory of Open Access Journals (Sweden)

Stephan E. Vogel

2017-12-01

Full Text Available A small but growing body of evidence suggests a link between individual differences in processing the order of numerical symbols (e.g., deciding whether a set of digits is arranged in ascending/descending order or not and arithmetic achievement. However, the reliability of behavioral correlates measuring symbolic and non-symbolic numerical order processing and their relationship to arithmetic abilities remain poorly understood. The present study aims to fill this knowledge gap by examining the behavioral correlates of numerical and non-numerical order processing and their unique associations with arithmetic fluency at two different time points within the same sample of individuals. Thirty-two right-handed adults performed three order judgment tasks consisting of symbolic numbers (i.e., digits, non-symbolic numbers (i.e., dots, and letters of the alphabet. Specifically, participants had to judge as accurately and as quickly as possible whether stimuli were ordered correctly (in ascending/descending order, e.g., 2-3-4; ●●●●-●●●-●●; B-C-D or not (e.g., 4-5-3; ●●●●-●●●●●-●●●; D-E-C. Results of this study demonstrate that numerical order judgments are reliable measurements (i.e., high test-retest reliability, and that the observed relationship between symbolic number processing and arithmetic fluency accounts for a unique and reliable portion of variance over and above the non-symbolic number and the letter conditions. The differential association of symbolic and non-symbolic numbers with arithmetic support the view that processing the order of symbolic and non-symbolic numbers engages different cognitive mechanisms, and that the ability to process ordinal relationships of symbolic numbers is a reliable and unique predictor of arithmetic fluency.

The overall efficacy and safety profile of a new drug is partially evaluated by the therapeutic index in clinical studies and by the protective index (PI) in preclinical studies. In-silico predictive methods may facilitate the assessment of these indicators. Although QSAR and QSTR models can be used for predicting PI, their predictive capability has not been evaluated. To test this capability, we developed QSAR and QSTR models for predicting the activity and toxicity of anticonvulsants at accuracy levels above the literature-reported threshold (LT) of good QSAR models as tested by both the internal 5-fold cross validation and external validation method. These models showed significantly compromised PI predictive capability due to the cumulative errors of the QSAR and QSTR models. Therefore, in this investigation a new quantitative structure-index relationship (QSIR) model was devised and it showed improved PI predictive capability that superseded the LT of good QSAR models. The QSAR, QSTR and QSIR models were developed using support vector regression (SVR) method with the parameters optimized by using the greedy search method. The molecular descriptors relevant to the prediction of anticonvulsant activities, toxicities and PIs were analyzed by a recursive feature elimination method. The selected molecular descriptors are primarily associated with the drug-like, pharmacological and toxicological features and those used in the published anticonvulsant QSAR and QSTR models. This study suggested that QSIR is useful for estimating the therapeutic index of drug candidates. Copyright © 2016. Published by Elsevier Inc.

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))

1994-01-01

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.

A therapeutic and effective doctor-patient relationship and patient-doctor relationship is at the core of all successful medical care. The medical and psychological evaluation of a potential kidney donor serves to protect the long-term health of both the donor and the potential recipient. Careful assessment of risk and donor education is at the core of donor evaluation and the decision to progress with donation requires refined clinical judgment by the medical team and critical thinking by the donor. Increasing pressure to increase the numbers of living donor transplants and suggestions by some that the process should be commercialized make it timely to consider the nature of the relationship between the doctor and the patient in the unusual circumstance of living donation. A high rate of complications in recipients of purchased kidneys and a lack of knowledge of the fate of paid donors have been reported. Commercialization of transplantation undermines the therapeutic doctor-patient relationship and threatens the healthy development of the international transplant endeavor.

2002-04-01

This report summarizes the presentations, recommendations and conclusions of the Consultants' Meeting on Nuclear Data for Production of Therapeutic Radioisotopes. The purpose of this meeting was to discuss scientific and technical matters related to the subject and to advise the IAEA Nuclear Data Section (NDS) on the need and possible formation of a Coordinated Research Programme (CRP). Accurate and complete knowledge of nuclear data are essential for the production of radionuclides for therapy to achieve the specific activity and purity required for efficient and safe clinical application. The Consultants recommended updating and completing the data for production of radionuclides that are recognized to be important in therapy. In addition, the consultants recommend investigating other radionuclides that have a potential interest and for which there exists a medical rationale for therapeutic use. To date no serious effort has been devoted to evaluation of nuclear data for the reactor and accelerator production of therapeutic radionuclides. The IAEA is in the unique and privileged position to address this important public health related problem. Therefore, the consultants highly recommend the formation of a CRP with the title: 'Nuclear Data for Production of Therapeutic Radionuclides.' (author)

2007-01-01

Full Text Available Introduction The incidence of fractured frontal sinus walls vary from 6% to 12% of all craniofacial injuries. Objective Estimated relation between clinical findings and performed therapeutic procedures in treating fractured frontal sinus walls. To estimate success in performed therapeutic procedures, according to the incidence of postoperative complications and the integrity of injured regions from the functional and esthetical aspect. Method We analyzed, by retrospective clinical investigation, 19 patients with fractured frontal sinus walls and dislocated fragments, treated at the Department for Maxillofacial Surgery, Clinic of Dentistry in Niš, in the period March 1995 - March 2006. The success of therapy was estimated based on the incidence and type of complications and esthetical results in relation to preoperative findings. Results Predominant etiological factor in fractures of frontal sinus walls is trauma sustained in traffic accidents, which occurred in 52.6% of patients in our investigation. In clinical findings, the impression was the predominant sign, present in 16 patients. In 6 cases soft tissue access through already present lacerations or their extensions was employed, in 4 cases it was done by supraciliary access and in 9 by bicoronal access. As a therapeutic measure, drainage was performed in 5 cases, cranialisation in one, ostheoneogenetic access in 11 cases and a simple reposition of fragments in 2 patients with fractured frontal sinus walls. Infection as a complication was absent. All patients were satisfied with postoperative esthetical appearance of the injured region. Conclusion The infection, the lacerations and the direction of fractured lines are dominant factors in the determination of therapeutic procedures used to treat fractured frontal sinus walls. This will result in the low incidence of infection as a postoperative complication and in patient’s satisfaction with postoperative esthetical result of the injured

D-amino acid-containing supramolecular nanofibers for potential cancer therapeutics.

2017-02-01

Nanostructures formed by peptides that self-assemble in water through non-covalent interactions have attracted considerable attention because peptides possess several unique advantages, such as modular design and easiness of synthesis, convenient modification with known functional motifs, good biocompatibility, low immunogenicity and toxicity, inherent biodegradability, and fast responses to a wide range of external stimuli. After about two decades of development, peptide-based supramolecular nanostructures have already shown great potentials in the fields of biomedicine. Among a range of biomedical applications, using such nanostructures for cancer therapy has attracted increased interests since cancer remains the major threat for human health. Comparing with L-peptides, nanostructures containing peptides made of D-amino acid (i.e., D-peptides) bear a unique advantage, biostability (i.e., resistance towards most of endogenous enzymes). The exploration of nanostructures containing D-amino acids, especially their biomedical applications, is still in its infancy. Herein we review the recent progress of D-amino acid-containing supramolecular nanofibers as an emerging class of biomaterials that exhibit unique features for the development of cancer therapeutics. In addition, we give a brief perspective about the challenges and promises in this research direction. Copyright © 2016 Elsevier B.V. All rights reserved.

«Paralipomena» on uniqueness in inverse scattering from a finite number of data

Directory of Open Access Journals (Sweden)

R. Persico

2007-06-01

Full Text Available This paper shows new proof of non-uniqueness of the solution for the retrieving of a compact-supported function starting from a finite number of samples of its spectrum. As will be shown, this is relevant for linear inverse scattering problems, that in many cases can be recast as the reconstruction of a compact supported function from a finite set of samples of its spectrum. Since this reconstruction is not unique, from a practical point of view, any linear inverse scattering algorithm that can be recast in terms of a Fourier relationship between unknowns and data necessarily «trusts» on the absence of invisible objects in the particular situation at hand.

Dysphoria has recently been conceptualized as a complex emotional state that consists of discontent and/or unhappiness and a predominantly externalizing mode of coping with these feelings. The Nepean Dysphoria Scale (NDS) was developed on the basis of this model of dysphoria and used in this clinical study to ascertain the specificity of the relationships between dysphoria and relevant domains of psychopathology. Ninety-six outpatients completed the NDS, Symptom Checklist 90-Revised (SCL-90R) and Depression, Anxiety, Stress Scales, 21-item version (DASS-21). The scores on the NDS subscales (Discontent, Surrender, Irritability and Interpersonal Resentment) and total NDS scores correlated significantly with scores on the DASS-21 scales and relevant SCL-90R subscales. Multiple regression analyses demonstrated the following: DASS-21 Depression and Stress each had unique relationships with NDS Discontent and Surrender; DASS-21 Anxiety had a unique relationship with NDS Discontent; SCL-90R Hostility and Paranoid Ideation and DASS-21 Stress each had unique relationships with NDS Irritability; and SCL-90R Paranoid Ideation and DASS-21 Stress, Depression and Anxiety each had unique relationships with NDS Interpersonal Resentment. These findings support the notion that dysphoria is a complex emotional state, with both non-specific and specific relationships with irritability, tension, depression, paranoid tendencies, anxiety, hostility and interpersonal sensitivity. Conceptual rigor when referring to dysphoria should be promoted in both clinical practice and further research.

Mining of seafloor massive sulfides (SMS) is imminent, but the ecology of assemblages at SMS deposits is poorly known. Proposed conservation strategies include protected areas to preserve biodiversity at risk from mining impacts. Determining site suitability requires biological characterisation of the mine site and protected area(s). Video survey of a proposed mine site and protected area off New Zealand revealed unique megafaunal assemblages at the mine site. Significant relationships were identified between assemblage structure and environmental conditions, including hydrothermal features. Unique assemblages occurred at both active and inactive chimneys and are particularly at risk from mining-related impacts. The occurrence of unique assemblages at the mine site suggests that the proposed protected area is insufficient alone and should instead form part of a network. These results provide support for including hydrothermally active and inactive features within networks of protected areas and emphasise the need for quantitative survey data of proposed sites.

Relationships between moment magnitude and fault parameters: theoretical and semi-empirical relationships

Science.gov (United States)

Wang, Haiyun; Tao, Xiaxin

2003-12-01

Fault parameters are important in earthquake hazard analysis. In this paper, theoretical relationships between moment magnitude and fault parameters including subsurface rupture length, downdip rupture width, rupture area, and average slip over the fault surface are deduced based on seismological theory. These theoretical relationships are further simplified by applying similarity conditions and an unique form is established. Then, combining the simplified theoretical relationships between moment magnitude and fault parameters with seismic source data selected in this study, a practical semi-empirical relationship is established. The seismic source data selected is also to used to derive empirical relationships between moment magnitude and fault parameters by the ordinary least square regression method. Comparisons between semi-empirical relationships and empirical relationships show that the former depict distribution trends of data better than the latter. It is also observed that downdip rupture widths of strike slip faults are saturated when moment magnitude is more than 7.0, but downdip rupture widths of dip slip faults are not saturated in the moment magnitude ranges of this study.

Strategies utilizing Toll-like receptor 4 (TLR4) agonists for treatment of cancer, infectious diseases, and other targets report promising results. Potent TLR4 antagonists are also gaining attention as therapeutic leads. Though some principles for TLR4 modulation by lipid A have been described, a thorough understanding of the structure-activity relationship (SAR) is lacking. Only through a complete definition of lipid A-TLR4 SAR is it possible to predict TLR4 signaling effects of discrete lipid A structures, rendering them more pharmacologically relevant. A limited 'toolbox' of lipid A-modifying enzymes has been defined and is largely composed of enzymes from mesophile human and zoonotic pathogens. Expansion of this 'toolbox' will result from extending the search into lipid A biosynthesis and modification by bacteria living at the extremes. Here, we review the fundamentals of lipid A structure, advances in lipid A uses in TLR4 modulation, and the search for novel lipid A-modifying systems in extremophile bacteria.

GABA(B) receptors, schizophrenia and sleep dysfunction: a review of the relationship and its potential clinical and therapeutic implications.

Science.gov (United States)

Kantrowitz, Joshua; Citrome, Leslie; Javitt, Daniel

2009-08-01

Evidence for an intrinsic relationship between sleep, cognition and the symptomatic manifestations of schizophrenia is accumulating. This review presents evidence for the possible utility of GABA(B) receptor agonists for the treatment of subjective and objective sleep abnormalities related to schizophrenia. At the phenotypic level, sleep disturbance occurs in 16-30% of patients with schizophrenia and is related to reduced quality of life and poor coping skills. On the neurophysiological level, studies suggest that sleep deficits reflect a core component of schizophrenia. Specifically, slow-wave sleep deficits, which are inversely correlated with cognition scores, are seen. Moreover, sleep plays an increasingly well documented role in memory consolidation in schizophrenia. Correlations of slow-wave sleep deficits with impaired reaction time and declarative memory have also been reported. Thus, both behavioural insomnia and sleep architecture are critical therapeutic targets in patients with schizophrenia. However, long-term treatment with antipsychotics often results in residual sleep dysfunction and does not improve slow-wave sleep, and adjunctive GABA(A) receptor modulators, such as benzodiazepines and zolpidem, can impair sleep architecture and cognition in schizophrenia. GABA(B) receptor agonists have therapeutic potential in schizophrenia. These agents have minimal effect on rapid eye movement sleep while increasing slow-wave sleep. Preclinical associations with increased expression of genes related to slow-wave sleep production and circadian rhythm function have also been reported. GABA(B) receptor deficits result in a sustained hyperdopaminergic state and can be reversed by a GABA(B) receptor agonist. Genetic, postmortem and electrophysiological studies also associate GABA(B) receptors with schizophrenia. While studies thus far have not shown significant effects, prior focus on the use of GABA(B) receptor agonists has been on the positive symptoms of

Over the last few years, Internet has become an integral part of daily life. An abundant source of information and a principal gateway of communication between individuals, Internet has been continuously gaining considerable ground as a tool of awareness and intervention in the area of public health. With regard to the field of mental health, Internet exhibits a credible potential in facilitating dialogue not only between experts and their beneficiaries but also between stakeholders. Moreover and with regard to various aspects of public concern, it can serve as a circulation portal of educational material between students and teachers. The advent of remote support services dates back in the decade of 1970-1980. In the present time, they consist of informative guides and self-help groups or online counselling. The latter is defined as the process in which both parties, namely the therapist and the client, are involved in an oral or written conciliation through means of an internet connection, videoconferencing, live chat or e-mail exchange. The benefits of this practice - accessibility, relocation, convenience, anonymity, facilitation of face-to-face psychotherapy and low cost - could make online counseling, in specific cases, the treatment of choice. While the usage of the World Wide Web seems promising for the rectification of mental health disorders, there is some debate among experts regarding the ethical aspect of practicing psychotherapy in an interactive digital environment. Issues such as technical expertise and the tackling of related problems, difficulties in the diagnostic process, interchange of verbal and nonverbal cues, crisis management, safeguarding the therapeutic alliance, protection of personal data, age restriction, keeping boundaries in relation to the setting, the time and the dynamics of the therapeutic relationship and, finally, training and supervisory process of online therapist, are some subjects of disagreement.

Therapeutic spaces of care farming: Transformative or ameliorating?

Science.gov (United States)

Kaley, Alexandra; Hatton, Chris; Milligan, Christine

2018-05-04

Since Wil Gesler's earliest articulation (Gesler, 1992; Gesler, 1996) key thinkers in the field of therapeutic landscapes have sought to emphasise the embodied, contextual and wholly relational nature of the relationship that exists between people and place. However, the extant research has tended to focus on the relational healing experience as this occurs 'in the moment' and with reference to a specific location or site of healing, with less attention being paid to what happens to people when they return to their ordinary or everyday places. In this paper, we reflect on findings from visual ethnographic work (including photography and film) that explored the therapeutic landscape experiences of people with intellectual disabilities engaged in care farming interventions for health and wellbeing. The study also recruited farm staff and family members or carers to take part, and comprised 20 participants in total. Having identified a gap in our understanding, consideration is given to wider impact that engaging in these sorts of activities had on the everyday lives of the participants in this study. We argue that this study has identified two types of therapeutic journey that broadly fit the experiences of study participants. The first type of journey denotes landscape experiences that are transformative. Here the therapeutic power of the care farm landscape resides in the ability of activities conducted on care farms to influence other aspects of participants' lives in ways that promote wellbeing. By contrast, there is another type of journey where the therapeutic power of the care farm resides in its ability to ameliorate challenging or harmful life situations, thus offering people a temporary site of respite or refuge. We conclude that these findings denote an important development for this sub-field of health geography, not only because they draw attention to the transformative power of the therapeutic encounter, but also the broader socio-spatial environments

Therapeutically targeting cyclin D1 in primary tumors arising from loss of Ini1

Rhabdoid tumors (RTs) are rare, highly aggressive pediatric malignancies with poor prognosis and with no standard or effective treatment strategies. RTs are characterized by biallelic inactivation of the INI1 tumor suppressor gene. INI1 directly represses CCND1 and activates cyclin-dependent kinase (cdk) inhibitors p16Ink4a and p21CIP. RTs are exquisitely dependent on cyclin D1 for genesis and survival. To facilitate translation of unique therapeutic strategies, we have used genetically engineered, Ini1+/− mice for therapeutic testing. We found that PET can be used to noninvasively and accurately detect primary tumors in Ini1+/− mice. In a PET-guided longitudinal study, we found that treating Ini1+/− mice bearing primary tumors with the pan-cdk inhibitor flavopiridol resulted in complete and stable regression of some tumors. Other tumors showed resistance to flavopiridol, and one of the resistant tumors overexpressed cyclin D1, more than flavopiridol-sensitive cells. The concentration of flavopiridol used was not sufficient to down-modulate the high level of cyclin D1 and failed to induce cell death in the resistant cells. Furthermore, FISH and PCR analyses indicated that there is aneuploidy and increased CCND1 copy number in resistant cells. These studies indicate that resistance to flavopiridol may be correlated to elevated cyclin D1 levels. Our studies also indicate that Ini1+/− mice are valuable tools for testing unique therapeutic strategies and for understanding mechanisms of drug resistance in tumors that arise owing to loss of Ini1, which is essential for developing effective treatment strategies against these aggressive tumors.

Dahlin, Moa Kindström; Leviner, Pernilla; Kaldal, Anna; Gumpert, Clara Hellner

2010-01-01

This paper presents a brief overview of the legal theoretical problems that arise in connection with the societal ambition of protecting vulnerable groups. One of the central difficulties in legislation with proactive and therapeutic ambitions arises from the link between law and philosophy of science, i.e., the relationship between facts and norms. It is shown that Therapeutic Jurisprudence differs in several aspects from Swedish legal scholarship that follows Scandinavian Legal Realism. It is also demonstrated that Therapeutic Jurisprudence has several similarities with the so-called Proactive Approach. This paper suggests that Therapeutic Jurisprudence may serve as a useful legal theoretical perspective in Swedish legal scholarship, especially when studying complex and vague regulations with a future focus. Two examples from Swedish legislation are examined: (a) Laws regulating compulsory care of abused or neglected children, and (b) laws related to the mentally ill. This paper illustrates the complexity in these acts, and poses the question of whether the regulations serve their purpose of providing adequate care for and protection of those in need.

Kim, Hyunah; Yoo, Su Jin; Kang, Hyun Ah

2015-02-01

The production of recombinant therapeutic proteins is one of the fast-growing areas of molecular medicine and currently plays an important role in treatment of several diseases. Yeasts are unicellular eukaryotic microbial host cells that offer unique advantages in producing biopharmaceutical proteins. Yeasts are capable of robust growth on simple media, readily accommodate genetic modifications, and incorporate typical eukaryotic post-translational modifications. Saccharomyces cerevisiae is a traditional baker's yeast that has been used as a major host for the production of biopharmaceuticals; however, several nonconventional yeast species including Hansenula polymorpha, Pichia pastoris, and Yarrowia lipolytica have gained increasing attention as alternative hosts for the industrial production of recombinant proteins. In this review, we address the established and emerging genetic tools and host strains suitable for recombinant protein production in various yeast expression systems, particularly focusing on current efforts toward synthetic biology approaches in developing yeast cell factories for the production of therapeutic recombinant proteins. © FEMS 2015.

A tough-love pedagogy in rehabilitation: integration of rehabilitation ideology with local cultures.

Science.gov (United States)

Chang, Ling-Hui; Wang, Jye

2009-09-01

This study problematizes a unique therapeutic relationship in rehabilitation and how the interaction reflects the integration of rehabilitation ideology with local cultures. The data drew from a larger ethnographic study of a rehabilitation unit in Taiwan. Participants included 21 patient-caregiver pairs and their rehabilitation professionals. They participated in in-depth interviews and participant observation. A tough-love pedagogy emerged as a unique therapeutic relationship in the unit. Patients were asked to interpret the stress with therapy as an inevitable, beneficial experience toward recovery. A prevalent supposition that equated poor physical performance with weak morale legitimized the approach. Cultural metaphors used to describe and define rehabilitation transformed the stress that patients experienced with strenuous exercises into a beneficial substance that aids recovery. The transformation of the therapeutic relationship into a pedagogical one helped connect rehabilitation to shared educational experiences. In the unit, the complicit practice of therapists, caregivers, and patients established and perpetuated the practice of a tough-love pedagogy. The congruence between this tough-love approach and traditional Chinese pedagogical principles made the approach legitimate and desired.

Therapeutic alliance in schizophrenia: the role of recovery orientation, self-stigma, and insight.

The present study examined variables related to the quality of the therapeutic alliance in out-patients with schizophrenia. We expected recovery orientation and insight to be positively, and self-stigma to be negatively associated with a good therapeutic alliance. We expected these associations to be independent from age, clinical symptoms (i.e. positive and negative symptoms, depression), and more general aspects of relationship building like avoidant attachment style and the duration of treatment by the current therapist. The study included 156 participants with DSM-IV diagnoses of schizophrenia or schizoaffective disorder in the maintenance phase of treatment. Therapeutic alliance, recovery orientation, self-stigma, insight, adult attachment style, and depression were assessed by self-report. Symptoms were rated by interviewers. Hierarchical multiple regressions revealed that more recovery orientation, less self-stigma, and more insight independently were associated with a better quality of the therapeutic alliance. Clinical symptoms, adult attachment style, age, and the duration of treatment by current therapist were unrelated to the quality of the therapeutic alliance. Low recovery orientation and increased self-stigma might undermine the therapeutic alliance in schizophrenia beyond the detrimental effect of poor insight. Therefore in clinical settings, besides enhancing insight, recovery orientation, and self-stigma should be addressed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

A simple and sensitive HPLC-DAD detection method was established for the simultaneous determination of nine compounds including oxypaeoniflorin, albiflorin, paeoniflorin, benzoylpaeoniflorin, glycyrrhizic acid, liquiritin, isoliquiritin, liquiritigenin, and isoliquiritigenin in the Traditional Chinese Medicinal Prescription Shaoyao-Gancao-Tang (SGT) and we analyze the relationship between therapeutical effect and compatibility of medicines by using an Agilent extend-C18 column at a flow rate of 1 mL/min. The column temperature was maintained at 30°C and the detection wavelength was set at 230 nm for oxypaeoniflorin, albiflorin, paeoniflorin, benzoylpaeoniflorin, and glycyrrhizic acid; 276 nm for liquiritin and liquiritigenin; 360 nm for isoliquiritin and isoliquiritigenin. The total contents of the nine compounds in SGT varied from 4.65 to 20.06 mg/mL. The results of this study showed that the content of chemical compounds of Traditional Chinese Medicinal Prescription is mainly influenced by the dosage and compatibility of medicines and the therapeutical effect of Traditional Chinese Medicinal prescription is mainly influenced by the dosage and compatibility of medicines. The method could be suitable for quality control of SGT with bioactive multicompounds. PMID:25431610

the therapeutic alliance themes extracted were from patient perspectives. The relationship between adherence and therapeutic alliance was examined by 26 articles of which 57% showed some correlation between therapeutic alliance and adherence. Age moderated the relationship between therapeutic alliance and adherence with younger individuals and an autonomy support environment reporting improved adherence. Prioritized goals, autonomy support and motivation were facilitators of therapeutic alliance. Therapeutic Alliance has been studied in a limited extent in the rehabilitation literature with conflicting frameworks and findings. Potential benefits described for enhancing therapeutic alliance might include better exercise adherence. Several knowledge gaps have been identified with a potential for generating future research priorities for therapeutic alliance in musculoskeletal rehabilitation.

Therapeutic potential of carbohydrates as regulators of macrophage activation.

Lundahl, Mimmi L E; Scanlan, Eoin M; Lavelle, Ed C

2017-12-15

It is well established for a broad range of disease states, including cancer and Mycobacterium tuberculosis infection, that pathogenesis is bolstered by polarisation of macrophages towards an anti-inflammatory phenotype, known as M2. As these innate immune cells are relatively long-lived, their re-polarisation to pro-inflammatory, phagocytic and bactericidal "classically activated" M1 macrophages is an attractive therapeutic approach. On the other hand, there are scenarios where the resolving inflammation, wound healing and tissue remodelling properties of M2 macrophages are beneficial - for example the successful introduction of biomedical implants. Although there are numerous endogenous and exogenous factors that have an impact on the macrophage polarisation spectrum, this review will focus specifically on prominent macrophage-modulating carbohydrate motifs with a view towards highlighting structure-function relationships and therapeutic potential.

The therapeutic alliance in internet interventions: A narrative review and suggestions for future research.

Science.gov (United States)

Berger, Thomas

2017-09-01

Research on Internet interventions has grown rapidly over the recent years and evidence is growing that Internet-based treatments often result in similar outcomes as conventional face-to-face psychotherapy. Yet there are still unanswered concerns such as whether a therapeutic alliance can be established over the Internet and whether the alliance is important in this new treatment format. A narrative review of studies formally assessing the therapeutic alliance in Internet interventions was conducted. It is the first review summarizing findings on the therapeutic alliance that (i) distinguishes between different forms of Internet interventions and (ii) does not restrict itself to specific Internet-based treatment formats such as guided self-help treatments, e-mail or videoconferencing therapies. Independent of communication modalities, diagnostic groups and amount of contact between clients and therapists, client-rated alliance scores were high, roughly equivalent to alliance ratings found in studies on face-to-face therapy. Mixed results were found regarding the therapist-rated alliance and alliance-outcome associations. The review points to the limitations of the available evidence and identifies unanswered questions. It is concluded that one of the major tasks for future research is to identify unique characteristics of the therapeutic alliance in the different treatment formats.

Clients' acceptance and adherence with orthoses can be influenced by a clinician's communication skills. In this clinical note, we describe two communication techniques, in the context of therapeutic footwear. Person-centred communication involves engaging with and listening to the attitudes of the client towards their condition, as well as discussing acceptance and expectations, in a structured consultation. Building a relationship is crucial and requires clients to feel heard and understood. An important influence on the acceptance and adherence is that a client makes a conscious decision to receive their device. This active receipt can be facilitated through shared decision making, wherein clinicians give clear, relevant and meaningful examples, based on clinical evidence, and ensure this is understood. Two communication techniques for clinicians providing therapeutic footwear are described. These can be adapted for use with provision of other assistive technologies to improve client acceptance and adherence. Clinical relevance Small changes in how clinicians communicate to their clients in daily practice can have a big influence on the subsequent acceptance and adherence with therapeutic footwear and indeed other prescribed assistive technologies.

The pragmatics of therapeutic interaction: an empirical study.

Science.gov (United States)

Lepper, Georgia

2009-10-01

The research reported in this article aims to demonstrate a method for the systematic study of the therapist/patient interaction in psychoanalytic psychotherapy, drawing upon the tradition and methods of 'pragmatics'--the study of language in interaction. A brief introduction to the discipline of pragmatics demonstrates its relevance to the contemporary focus of clinical theory on the here-and-now dynamics of the relationship between analyst and patient. This is followed by a detailed study of five segments from the transcript of a therapeutic dialogue, drawn from a brief psychoanalytic psychotherapy, in which therapist and patient negotiate the meaning of the patient's symptom: Is it psychosomatic? The research seeks to show how the therapeutic process can be observed and studied as an interactional achievement, grounded in general and well-studied procedures through which meaning is intersubjectively developed and shared. Implications of the analysis for clinical theory and practice, and further research, are discussed.

There is little research on short-term treatments for borderline personality disorder (BPD). While the core changes may occur only in long-term treatments, short-term treatments may enable the study of early generic processes of engagement in therapy and thus inform about effective treatment components. It was shown that a 10-session version of a psychiatric treatment was effective in reducing borderline symptoms at the end of this treatment [Kramer, U., Kolly, S., Berthoud, L., Keller, S., Preisig, M., Caspar, F., … Despland, J.-N. (2014). Effects of motive-oriented therapeutic relationship in a ten-session general psychiatric treatment for borderline personality disorder: A randomized controlled trial. Psychotherapy and Psychosomatics, 83, 176-186.]. Also, it was demonstrated in a randomized design that adding the motive-oriented therapeutic relationship (MOTR), following an individualized case formulation based on Plan Analysis, further increased general outcome after session 10 and had a positive effect on the early changes in self-esteem and alliance. The present study focuses on the follow-up period after this initial treatment, examining treatment density and outcomes after 6 months and service utilization after 12 months. Outcome was measured using the OQ-45. Results on a sub-sample of N = 40 patients with available OQ-45 data at follow-up (n = 21 for MOTR-treatment, n = 19 for comparison treatment) showed maintenance of gains over the follow-up period, which did not differ between both conditions. It appeared for this sample that MOTR treatments, while using the same number of sessions, lasted more weeks (i.e., lower treatment density, defined as the number of sessions per week), when compared to the treatments without MOTR. Density marginally predicted symptom reduction at follow-up. Patients in MOTR treatments had a greater likelihood of entering structured psychotherapy after the initial sessions than patients in the comparison

Activation of innate immunity has direct effects in modulating viral replication, tumor growth, angiogenesis, and inflammatory and other immunological processes. It is now established that unmodified siRNA can activate this innate immune response and therefore there is real potential for siRNA to elicit nonspecific therapeutic effects in a wide range of disease models. Here we demonstrate that in a murine model of influenza infection, the antiviral activity of siRNA is due primarily to immune stimulation elicited by the active siRNA duplexes and is not the result of therapeutic RNA interference (RNAi) as previously reported. We show that the misinterpretation stems from the use of a particular control green fluorescent protein (GFP) siRNA that we identify as having unusually low immunostimulatory activity compared with the active anti-influenza siRNA. Curiously, this GFP siRNA has served as a negative control for a surprising number of groups reporting therapeutic effects of siRNA. The inert immunologic profile of the GFP sequence was unique among a broad panel of published siRNAs, all of which could elicit significant interferon induction from primary immune cells. This panel included eight active siRNAs against viral, angiogenic, and oncologic targets, the reported therapeutic efficacy of which was based on comparison with the nonimmunostimulatory GFP siRNA. These results emphasize the need for researchers to anticipate, monitor, and adequately control for siRNA-mediated immune stimulation and calls into question the interpretation of numerous published reports of therapeutic RNAi in vivo. The use of chemically modified siRNA with minimal immunostimulatory capacity will help to delineate more accurately the mechanism of action underlying such studies.

Therapeutic Targets of Triglyceride Metabolism as Informed by Human Genetics.

2016-04-01

Human genetics has contributed to the development of multiple drugs to treat hyperlipidemia and coronary artery disease (CAD), most recently including antibodies targeting PCSK9 to reduce LDL cholesterol. Despite these successes, a large burden of CAD remains. Genetic and epidemiological studies have suggested that circulating triglyceride (TG)-rich lipoproteins (TRLs) are a causal risk factor for CAD, presenting an opportunity for novel therapeutic strategies. We discuss recent unbiased human genetics testing, including genome-wide association studies (GWAS) and whole-genome or -exome sequencing, that have identified the lipoprotein lipase (LPL) and hepatic lipogenesis pathways as important mechanisms in the regulation of circulating TRLs. Further strengthening the causal relationship between TRLs and CAD, findings such as these may provide novel targets for much-needed potential therapeutic interventions. Copyright © 2016.

Modularity, comparative cognition and human uniqueness.

Science.gov (United States)

Shettleworth, Sara J

2012-10-05

Darwin's claim 'that the difference in mind between man and the higher animals … is certainly one of degree and not of kind' is at the core of the comparative study of cognition. Recent research provides unprecedented support for Darwin's claim as well as new reasons to question it, stimulating new theories of human cognitive uniqueness. This article compares and evaluates approaches to such theories. Some prominent theories propose sweeping domain-general characterizations of the difference in cognitive capabilities and/or mechanisms between adult humans and other animals. Dual-process theories for some cognitive domains propose that adult human cognition shares simple basic processes with that of other animals while additionally including slower-developing and more explicit uniquely human processes. These theories are consistent with a modular account of cognition and the 'core knowledge' account of children's cognitive development. A complementary proposal is that human infants have unique social and/or cognitive adaptations for uniquely human learning. A view of human cognitive architecture as a mosaic of unique and species-general modular and domain-general processes together with a focus on uniquely human developmental mechanisms is consistent with modern evolutionary-developmental biology and suggests new questions for comparative research.

Therapeutic CPAP Level Predicts Upper Airway Collapsibility in Patients With Obstructive Sleep Apnea.

Upper airway collapsibility is a key determinant of obstructive sleep apnea (OSA) which can influence the efficacy of certain non-continuous positive airway pressure (CPAP) treatments for OSA. However, there is no simple way to measure this variable clinically. The present study aimed to develop a clinically implementable tool to evaluate the collapsibility of a patient's upper airway. Collapsibility, as characterized by the passive pharyngeal critical closing pressure (Pcrit), was measured in 46 patients with OSA. Associations were investigated between Pcrit and data extracted from patient history and routine polysomnography, including CPAP titration. Therapeutic CPAP level, demonstrated the strongest relationship to Pcrit (r2=0.51, p CPAP level (6.2 ± 0.6 vs. 10.3 ± 0.4 cmH2O, p -2 cmH2O). A therapeutic CPAP level ≤8.0 cmH2O was sensitive (89%) and specific (84%) for detecting a mildly collapsible upper airway. When applied to the independent validation data set (n = 74), this threshold maintained high specificity (91%) but reduced sensitivity (75%). Our data demonstrate that a patient's therapeutic CPAP requirement shares a strong predictive relationship with their Pcrit and may be used to accurately differentiate OSA patients with mild airway collapsibility from those with moderate-to-severe collapsibility. Although this relationship needs to be confirmed prospectively, our findings may provide clinicians with better understanding of an individual patient's OSA phenotype, which ultimately could assist in determining which patients are most likely to respond to non-CPAP therapies. © Sleep Research Society 2017.

Moore, Theresa; Ting, Brigid; Rossiter-Thornton, Maria

2008-09-01

This pilot study explored the experience of participating in a Therapeutic Touch practice group. A qualitative descriptive-exploratory method was used, involving 12 members of practice groups in Ontario and British Columbia, Canada. Analysis of the data using an extraction-synthesis process yielded four themes: (a) learning with others through sharing and hands-on experience is valued; (b) connecting with a network of supportive relationships that sustain self and Therapeutic Touch practice; (c) comfort-discomfort arising with self, others, or ideas; and (d) meaningful changes emerge while experiencing group energy and Therapeutic Touch. The findings expand current knowledge about the positive aspects of participating in practice groups and provide a beginning understanding of member discomfort, which had not been previously reported. This knowledge will be useful to Therapeutic Touch organizations, practice group leaders, and group members. It will also guide health care agencies and practitioners of other healing modalities who may be considering establishing practice groups.

Highly active antiretroviral therapy including protease inhibitors does not confer a unique CD4 cell benefit. The AVANTI and INCAS Study Groups.

2000-07-07

To determine if triple combination therapy, particularly including HIV protease inhibitors (PI), confers an unique immunological benefit that is independent of reductions of plasma viral load (pVL). The correlation between changes from baseline in CD4 cell count and pVL was examined at all time points up to 52 weeks in three randomized clinical trials (AVANTI-2, AVANTI-3 and INCAS) that compared dual nucleoside therapy with triple combination therapy. Individual pVL and CD4 cell counts changes from baseline were entered into multivariate linear regression models for patients receiving double therapy and for those receiving triple therapy including a PI and/or a non-nucleoside reverse transcriptase inhibitor (NNRTI), and the null hypothesis was tested. After 52 weeks of therapy, the relationship between changes from baseline CD4 cell count and pVL was independent of whether patients were assigned double or triple therapy (P = 0.23 and 0.69 for intercept and slope, respectively), or whether patients were assigned triple therapy including a PI or triple therapy including an NNRTI (P = 0.92 and 0.95, respectively). Less than 5% of patients ever had 'discordant' increases in both CD4 cell count and pVL compared with baseline, and this proportion was unrelated to the class of therapy used. 'Discordant' decreases from baseline in both parameters were observed in up to 35% of individuals. The correlation between pVL and CD4 cell count changes from baseline improved over time on therapy, regardless of the therapeutic regimen involved. The data provide no evidence for a CD4 cell count benefit of highly active antiretroviral therapy (HAART) unique to triple therapy or PI-containing regimens.

Perceptions of Parent-Child Attachment Relationships and Friendship Qualities: Predictors of Romantic Relationship Involvement and Quality in Adolescence.

2017-05-01

Relationships with parents and friends are important contexts for developing romantic relationship skills. Parents and friends may influence both the timing of involvement and the quality of romantic relationships. Three models of the joint influence of parents and friends (direct effects model, mediation model, and moderator model) have been proposed. The present study uses data from a longitudinal study (n = 1012; 49.8% female; 81.1% Caucasian) to examine how attachment and friendship quality at age 10 years predict romantic relationship involvement and quality at ages 12 and 15 years. The results supported the direct effects model, with attachment and friendship quality uniquely predicting different romantic relationship outcomes. The findings provide further support for the important influence of family and friends on early romantic relationships.

Biominetic High Density Lipoproteins for the Delivery of Therapeutic Oligonucleotides

Science.gov (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

2009-06-01

Combinatorial biocatalysis was applied to generate a diverse set of dihydroxymethylzearalenone analogs with modified ring structure. In one representative chemoenzymatic reaction sequence, dihydroxymethylzearalenone was first subjected to a unique enzyme-catalyzed oxidative ring opening reaction that creates two new carboxylic groups on the molecule. These groups served as reaction sites for further derivatization involving biocatalytic ring closure reactions with structurally diverse bifunctional reagents, including different diols and diamines. As a result, a library of cyclic bislactones and bislactams was created, with modified ring structures covering chemical space and structure activity relationships unattainable by conventional synthetic means.

Shangri-La revisited: an exploration of therapeutic efficacy among intentional communities.

Science.gov (United States)

Francis, T L

1992-04-01

Field and literature surveys were employed to explore the therapeutic efficacy of a reportedly common set of social structures found among some Intentional Communities (ICs). Substance misuse served as an example of social problems plausibly related to the examined social structures, which included: (1) meditative practices, (2) progressive education, (3) holistic health practices, (4) nutritional diet, (5) open policy making, (6) equally or equitably shared resources, (7) integrating membership processes, and (8) environmental concern. The field survey identified and examined 11 such ICs, and the literature exploration concerning the structures found that they appear to be therapeutic. Future research should focus on refining the study of structural and antecedent variables and on finding relationships between these variables to communities in the larger society.

[Sudeck syndrome (CRPS) caused by unique personality traits: myth and fiction].

Science.gov (United States)

Lesky, J

2010-12-01

In analogy to the thesis of "pain-proneness", conceptualised by G. Engel more than 50 years ago, the idea of a unique structure in personality emerged, which was given a causal meaning in the development of Sudeck's Disease (now known as complex regional pain syndrome - CRPS), of which the pathogenesis is particularly unknown until today. It was supposed that certain psychological traits predispose one to develop CRPS. Predisposition in this context was apprehended as a personal susceptibility to produce and maintain an excessive reaction to nociceptive stimulations. This model has been maintained for a long time and was the subject of scientific examination just in the last two decades. Some publications reporting sporadic correlations between CRPS and certain personality traits, for example anxiety, neuroticism and depressive mood, are presented as are also 15 current empirical studies and five reviews, which deal in a more differentiated manner with the formulated question and lead to sobering results. The relevant state of research as well as the fundamental and methodical difficulties in regard to verifying a CRPS personality or pain-prone personality are discussed critically. In general, there is a lack of high-quality relevant studies. Some retrospective/cross-sectional studies yield contradictory results regarding psychological problems in patients with CRPS but the majority shows no association, and studies with higher methodological quality tend to the conclusion of no relationship between psychological factors like depression, anxiety, neuroticism, or anger and CRPS. Especially, the few prospective studies do not report such a relationship, psychological factors are not associated with CRPS onset. Compared to other patients with chronic pain there is no unique disturbed psychological profile and no higher degree of psychosocial disturbance in CRPS patients. In all, the results of research cannot confirm the hypothesis of correlations between

Corrective interpersonal experience in psychodrama group therapy: a comprehensive process analysis of significant therapeutic events.

McVea, Charmaine S; Gow, Kathryn; Lowe, Roger

2011-07-01

This study investigated the process of resolving painful emotional experience during psychodrama group therapy, by examining significant therapeutic events within seven psychodrama enactments. A comprehensive process analysis of four resolved and three not-resolved cases identified five meta-processes which were linked to in-session resolution. One was a readiness to engage in the therapeutic process, which was influenced by client characteristics and the client's experience of the group; and four were therapeutic events: (1) re-experiencing with insight; (2) activating resourcefulness; (3) social atom repair with emotional release; and (4) integration. A corrective interpersonal experience (social atom repair) healed the sense of fragmentation and interpersonal disconnection associated with unresolved emotional pain, and emotional release was therapeutically helpful when located within the enactment of this new role relationship. Protagonists who experienced resolution reported important improvements in interpersonal functioning and sense of self which they attributed to this experience.

Therapeutic Mechanisms of Bile Acids and Nor-Ursodeoxycholic Acid in Non-Alcoholic Fatty Liver Disease.

Steinacher, Daniel; Claudel, Thierry; Trauner, Michael

2017-01-01

Non-alcoholic fatty liver disease is one of the most rapidly rising clinical problems in the 21st century. So far no effective drug treatment has been established to cure this disease. Bile acids (BAs) have a variety of signaling properties, which can be used therapeutically for modulating hepatic metabolism and inflammation. A side-chain shorted derivative of ursodeoxycholic acid (UDCA) is 24 nor-ursodeoxycholic acid (NorUDCA) and it represents a new class of drugs for treatment of liver diseases. NorUDCA has unique biochemical and therapeutic properties, since it is relatively resistant to conjugation with glycine or taurine compared to UDCA. NorUDCA undergoes cholehepatic shunting, resulting in ductular targeting, bicarbonate-rich hypercholeresis, and cholangiocyte protection. Furthermore, it showed anti-fibrotic, anti-inflammatory, and anti-lipotoxic properties in several animal models. As such, NorUDCA is a promising new approach in the treatment of cholestatic and metabolic liver diseases. This review is a summary of current BA-based therapeutic approaches in the treatment of the fatty liver disease. © 2017 S. Karger AG, Basel.

Risk evaluation and monitoring in multiple sclerosis therapeutics.

Clanet, Michel C; Wolinsky, Jerry S; Ashton, Raymond J; Hartung, Hans-Peter; Reingold, Stephen C

2014-09-01

Risk for multiple sclerosis (MS) disease-modifying therapies (DMT) must be assessed on an ongoing basis. Early concerns regarding the first-approved DMTs for MS have been mitigated, but recently licensed therapies have been linked to possibly greater risks. The objective of this review is to discuss risk assessment in MS therapeutics based on an international workshop and comprehensive literature search and recommend strategies for risk assessment/monitoring. Assessment and perception of therapeutic risks vary between patients, doctors and regulators. Acceptability of risk depends on the magnitude of risk and the demonstrated clinical benefits of any agent. Safety signals must be distinguishable from chance occurrences in a clinical trial and in long-term use of medications. Post-marketing research is crucial for assessing longer-term safety in large patient cohorts. Reporting of adverse events is becoming more proactive, allowing more rapid identification of risks. Communication about therapeutic risks and their relationship to clinical benefit must involve patients in shared decision making. It is difficult to produce a general risk-assessment algorithm for all MS therapies. Specific algorithms are required for each DMT in every treated-patient population. New and evolving risks must be evaluated and communicated rapidly to allow patients and physicians to be well informed and able to share treatment decisions. © The Author(s) 2013.

Sabatine, Elaina; Lippold, Melissa; Kainz, Kirsten

2017-11-01

Parent and school bonds are protective against delinquency. This study used longitudinal data and multilevel Poisson regression models (MLM) to examine unique and interactive associations of parent and school bonds on youth delinquency in a sample of rural adolescents ( n = 945; 84% White). We investigated whether youth sex or transitioning to a new middle school moderated the linkages between parent and school bonds and later delinquency. Results indicated reduced delinquency was associated with positive parent and school relationships. Parent and school bonds interacted such that linkages between parent bonding and youth delinquency were stronger when youth also had high school bonding - suggesting an additive effect. However, interactive effects were only found when youth remained in the same school and became nonsignificant if they transitioned to a new school. Findings support prior evidence that parent and school bonds - and their interaction - play a unique role in reducing delinquency.

Decalogue of the Spanish Society of Arteriosclerosis to reduce therapeutic inertia.

Science.gov (United States)

Blasco, Mariano; Pérez-Martínez, Pablo; Lahoz, Carlos

Therapeutic inertia (TI) is defined as the failure of the physician to initiate or intensify a treatment when the therapeutic goal has not been achieved. TI can be of 2types: inertia due to lack of prescription of drugs and inertia in the absence of control of a risk factor. The consequences of TI are poor control of risk factors, an increase in potentially preventable events and an increase in costs. There are factors of the doctor himself, the patient and the care organization that determine the presence of TI. Ten measures are proposed to reduce TI: to promote continuing education, to define clearly therapeutic objectives, to establish audits, to implement computerized medical records with alerts, to encourage research in this field, to disseminate clinical practice guidelines, to create motivational incentives, to organize care, to improve the doctor-patient relationship and to involve other health care providers.

Full Text Available Do forgiveness and conflict tactics (compromise, aggression, and avoidancein response to conflicts instigated by a romantic partner's offence uniquely predict effective arguing and relationship quality? Using 92 Italian couples we tested a mediational model in which each partner's responses to conflict predicted bothe partners' perceived effective arguing that, in turn, predict their own relationship quality. For both men and women, negative responses to conflict (unforgiveness, aggression, and avoidance overlapped and jointly predicted self-reported and partner-reported relationship quality, directly and indirectly via effective arguing. Positive responses investigated (benevolence and compromise did not overlap for either men or women. Men's positive positive responses to conflict uniquely predicted self-reported and partner-reported relationship quality via effective arguing, whereas women's positive responses did not predict them independently of their male partner's tactics.

Differences and similarities in therapeutic mode use between occupational therapists and occupational therapy students in Norway.

Carstensen, Tove; Bonsaksen, Tore

2017-11-01

The Intentional Relationship Model (IRM) is a new model of the therapeutic relationship in occupational therapy practice. Two previous studies have focused on therapist communication style, or 'mode' use, but to date no group comparisons have been reported. To explore differences between occupational therapists and occupational therapy students with regard to their therapeutic mode use. The study had a cross-sectional design, and convenience samples consisting of occupational therapists (n = 109) and of second-year occupational therapy students (n = 96) were recruited. The Self-Assessment of Modes Questionnaire was the main data collection tool. Group differences were analysed with independent t-tests. The occupational therapists responded more within the collaborative and empathizing modes than the students did. The students responded more within the advocating and instructing modes than the occupational therapists did. There may be systematic differences between occupational therapists and students concerning their therapeutic mode use. Some modes, such as the collaborating and empathizing modes, may be viewed as requiring more experience, whereas other modes, such as the advocating mode may be related to more recent rehabilitation ideologies. These factors may contribute to explaining several of the group differences observed.

Selmi, Carlo

2014-08-01

Clinicians are facing unexpected issues in everyday practice, and these may become counterintuitive or challenging. Illustrative examples are provided by the hypersensitivity to universally used immunosuppressants such as corticosteroids or antibiotics such as beta-lactam. Secondly, additional issues are represented by the discovery of new pathogenetic mechanisms involved in rheumatoid and psoriatic arthritis or other chronic inflammatory diseases, genomic susceptibility to enigmatic diseases such as giant cell arteritis, or the shared role of specific mediators such as semaphorins. Third, the therapeutic armamentarium has dramatically changed over the past decade following the introduction of biotechnological drugs, and new mechanisms are being proposed to reduce adverse events or increase the drug effectiveness, particularly on cardiovascular comorbidities. Finally, rare diseases continue to represent difficult cases, as for Cogan's syndrome, with limited literature available for clinical recommendations. For these reason, the present issue of Clinical Reviews in Allergy and Immunology is timely and dedicated to these and other unique topics in clinical immunology and allergy. The aim of this issue is thus to help clinicians involved in internal medicine as well as allergists and clinical immunologists while discussing new pathways that will prove important in the near future.

Vitamin A-aldehyde adducts: AMD risk and targeted therapeutics.

Sparrow, Janet R

2016-04-26

Although currently available treatment options for age-related macular degeneration (AMD) are limited, particularly for atrophic AMD, the identification of predisposing genetic variations has informed clinical studies addressing therapeutic options such as complement inhibitors and anti-inflammatory agents. To lower risk of early AMD, recommended lifestyle interventions such as the avoidance of smoking and the intake of low glycemic antioxidant-rich diets have largely followed from the identification of nongenetic modifiable factors. On the other hand, the challenge of understanding the complex relationship between aging and cumulative damage leading to AMD has fueled investigations of the visual cycle adducts that accumulate in retinal pigment epithelial (RPE) cells and are a hallmark of aging retina. These studies have revealed properties of these compounds that provide insights into processes that may compromise RPE and could contribute to disease mechanisms in AMD. This work has also led to the design of targeted therapeutics that are currently under investigation.

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. PMID:27510556

Full Text Available The results showed that there was significant difference between husbands’ and their wives' marital satisfaction. Stepwise regression analyses revealed that relational skills and marriage duration were, respectively, significant predictors of husbands’ marital satisfaction. Also, relational skills and some of relational beliefs- such as "things should always be perfect between us", "we should do everything together" and "romanticism", had significant contribution in prediction of wives’ martial satisfaction, respectively. Contributions of other relational beliefs were not significant. These results clarified the role of relational shills and relational beliefs in marital satisfaction, and confirmed that cognitive-behavior approaches, through training relational skills for couples, and therapeutic interventions to change wives' irrational beliefs would be effective in treating marital problems. This Study, according to cognitive-behavior approach, tries to investigate the role of relationship beliefs and relationship skills in couples' marital satisfaction. To do so, 160 persons (80 couples from Tabriz were selected.  After establishing the motivation for participation in the research and getting their informed consent, they were asked to fill out Relationship Beliefs Questionnaire (RBQ, Moradi's marital relationship skills questionnaire and marital satisfaction questionnaire (ENRICH.

2014-05-01

To determine the relationship between left ventricular cardiac output (LVCO), superior vena cava (SVC) flow, and brain injury during whole-body therapeutic hypothermia. Sixteen newborns with moderate or severe hypoxic-ischemic encephalopathy were studied using echocardiography during and immediately after therapeutic hypothermia. Measures were also compared with 12 healthy newborns of similar postnatal age. Newborns undergoing therapeutic hypothermia also had cerebral magnetic resonance imaging as part of routine clinical care on postnatal day 3-4. LVCO was markedly reduced (mean ± SD 126 ± 38 mL/kg/min) during therapeutic hypothermia, whereas SVC flow was maintained within expected normal values (88 ± 27 mL/kg/min) such that SVC flow represented 70% of the LVCO. The reduction in LVCO during therapeutic hypothermia was mainly accounted by a reduction in heart rate (99 ± 13 vs 123 ± 17 beats/min; P newborns without brain injury (P = .013). Newborns with perinatal hypoxic-ischemic encephalopathy showed a preferential systemic-to-cerebral redistribution of cardiac blood flow during whole-body therapeutic hypothermia, which may reflect a lack of cerebral vascular adaptation in newborns with more severe brain injury.

Type 1 diabetes is an autoimmune disease arising from the destruction of pancreatic insulin-producing beta cells. The disease represents a continuum, progressing sequentially at variable rates through identifiable stages prior to the onset of symptoms, through diagnosis and into the critical periods that follow, culminating in a variable depth of beta cell depletion. The ability to identify the very earliest of these presymptomatic stages has provided a setting in which prevention strategies can be trialled, as well as furnishing an unprecedented opportunity to study disease evolution, including intrinsic and extrinsic initiators and drivers. This niche opportunity is occupied by Type 1 Diabetes TrialNet, an international consortium of clinical trial centres that leads the field in intervention and prevention studies, accompanied by deep longitudinal bio-sampling. In this review, we focus on discoveries arising from this unique bioresource, comprising more than 70,000 samples, and outline the processes and science that have led to new biomarkers and mechanistic insights, as well as identifying new challenges and opportunities. We conclude that via integration of clinical trials and mechanistic studies, drawing in clinicians and scientists and developing partnership with industry, TrialNet embodies an enviable and unique working model for understanding a disease that to date has no cure and for designing new therapeutic approaches.

CONTEXT Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent and impairing psychiatric disorder that affects both children and adults. There are Food and Drug Administration-approved stimulant and nonstimulant medications for treating ADHD; however, little is known about the mechanisms by which these different treatments exert their therapeutic effects. OBJECTIVE To contrast changes in brain activation related to symptomatic improvement with use of the stimulant methylphenidate hydrochloride vs the nonstimulant atomoxetine hydrochloride. DESIGN Functional magnetic resonance imaging before and after 6 to 8 weeks of treatment with methylphenidate (n = 18) or atomoxetine (n = 18) using a parallel-groups design. SETTING Specialized ADHD clinical research program at Mount Sinai School of Medicine, New York, New York. PARTICIPANTS Thirty-six youth with ADHD (mean [SD] age, 11.2 [2.7] years; 27 boys) recruited from randomized clinical trials. MAIN OUTCOME MEASURES Changes in brain activation during a go/no-go test of response inhibition and investigator-completed ratings on the ADHD Rating Scale-IV-Parent Version. RESULTS Treatment with methylphenidate vs atomoxetine was associated with comparable improvements in both response inhibition on the go/no-go test and mean (SD) improvements in ratings of ADHD symptoms (55% [30%] vs 57% [25%]). Improvement in ADHD symptoms was associated with common reductions in bilateral motor cortex activation for both treatments. Symptomatic improvement was also differentially related to gains in task-related activation for atomoxetine and reductions in activation for methylphenidate in the right inferior frontal gyrus, left anterior cingulate/supplementary motor area, and bilateral posterior cingulate cortex. These findings were not attributable to baseline differences in activation. CONCLUSIONS Treatment with methylphenidate and atomoxetine produces symptomatic improvement via both common and divergent neurophysiologic

Full Text Available Roshan Kukreja,1 Bal Ram Singh2 1Department of Chemistry and Biochemistry, University of Massachusetts, 2Botulinum Research Center, Institute of Advanced Sciences, Dartmouth, MA, USA Abstract: Botulinum neurotoxins (BoNTs, the most potent toxins known to mankind, are metalloproteases that act on nerve–muscle junctions to block exocytosis through a very specific and exclusive endopeptidase activity against soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE proteins of presynaptic vesicle fusion machinery. This very ability of the toxins to produce flaccid muscle paralysis through chemical denervation has been put to good use, and these potentially lethal toxins have been licensed to treat an ever expanding list of medical disorders and more popularly in the field of esthetic medicine. In most cases, therapeutic BoNT preparations are high-molecular-weight protein complexes consisting of BoNT, complexing proteins, and excipients. There is at least one isolated BoNT, which is free of complexing proteins in the market (Xeomin®. Each commercially available BoNT formulation is unique, differing mainly in molecular size and composition of complexing proteins, biological activity, and antigenicity. BoNT serotype A is marketed as Botox®, Dysport®, and Xeomin®, while BoNT type B is commercially available as Myobloc®. Nerve terminal intoxication by BoNTs is completely reversible, and the duration of therapeutic effects of BoNTs varies for different serotypes. Depending on the target tissue, BoNTs can block the cholinergic neuromuscular or cholinergic autonomic innervation of exocrine glands and smooth muscles. Therapeutic BoNTs exhibit a high safety and very limited adverse effects profile. Despite their established efficacy, the greatest concern with the use of therapeutic BoNTs is their propensity to elicit immunogenic reactions that might render the patient unresponsive to subsequent treatments, particularly in chronic

The most common therapies for asthma and other chronic lung diseases are anti-inflammatory agents and bronchodilators. While these drugs oppose disease symptoms, they do not reverse established structural changes in the airways and their therapeutic efficacy is reduced with increasing disease severity. The peptide hormone, relaxin, is a Relaxin Family Peptide Receptor 1 (RXFP1) receptor agonist with unique combined effects in the lung that differentiates it from these existing therapies. Relaxin has previously been reported to have cardioprotective effects in acute heart failure as well anti-fibrotic actions in several organs. This review focuses on recent experimental evidence of the beneficial effects of chronic relaxin treatment in animal models of airways disease demonstrating inhibition of airway hyperresponsiveness and reversal of established fibrosis, consistent with potential therapeutic benefit. Of particular interest, accumulating evidence demonstrates that relaxin can also acutely oppose contraction by reducing the release of mast cell-derived bronchoconstrictors and by directly eliciting bronchodilation. When used in combination, chronic and acute treatment with relaxin has been shown to enhance responsiveness to both glucocorticoids and β 2 -adrenoceptor agonists respectively. While the mechanisms underlying these beneficial actions remain to be fully elucidated, translation of these promising combined preclinical findings is critical in the development of relaxin as a novel alternative or adjunct therapeutic opposing multiple aspects of airway pathology in lung diseases.

Vulpoi, Carmen; Ungureanu, Gabriel; Stoica, Ortansa

2007-01-01

The technological revolution of the 20th century has changed not only the life style but also the human interrelations, including the physician-patient relationship. The old, primarily patriarchal, system (in which the patient trusted completely the physician and followed religiously his commandments) evolved into the current system in which the patient is an active partner in medical care. Patient education is increasingly recognized as an integral part of the therapy. The objectives of therapeutical education rely essentially in the improvement of the patient knowledge and skills concerning the disease and its treatment in order to harmonize his life style with the restrains of the illness. Therapeutical education must be complex, individualized, repeated, motivating, and controlled. In chronic diseases, both the health provider and the patient are in front of a permanent challenge. The educational process is in continuous movement, liable to permanent improvement.

Sanctification and spiritual disclosure in parent-child relationships: implications for family relationship quality.

Brelsford, Gina M

2013-08-01

Social scientific research on family life, religion, and spirituality tends to focus on global religiousness and spirituality with few studies seeking to understand interpersonal religious and spiritual contributors, namely sanctification and spiritual disclosure, from multiple family members' perspectives. This study explored 91 mother-college student and 64 father-college student dyads who rated their use of spiritual disclosure and theistic and nontheistic sanctification of the parent-child dyad in relation to parent-child relationship quality (e.g., parent-child relationship satisfaction and open communication). Results indicate significant positive links between higher levels of spiritual disclosure and greater theistic and nontheistic sanctification, for mothers, fathers, and their children. However, only greater nontheistic sanctification and higher levels spiritual disclosure were significantly related to increased parent-child relationship quality. Through use of Actor-Partner Interdependence Models (APIMs) results indicated unique contributions of spiritual disclosure to parent-child relationship quality above nontheistic sanctification for open communication in the family. However, full models, which included nontheistic sanctification and spiritual disclosure, predict college students' relationship satisfaction with their mothers and fathers. Implications for interpersonal religiousness and spirituality as contributors to familial relationship quality in research and practice are discussed. © 2013 American Psychological Association

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? © 2013 New York Academy of Sciences.

The development of efficient strategies for generating fully human monoclonal antibodies with unique functional properties that are exploitable for tailored therapeutic interventions remains a major challenge in the antibody technology field. Here, we present a methodology for recovering such antibodies from antigen-encountered human B cell repertoires. As the source for variable antibody genes, we cloned immunoglobulin G (IgG)-derived B cell repertoires from lymph nodes of 20 individuals undergoing surgery for head and neck cancer. Sequence analysis of unselected “LYmph Node Derived Antibody Libraries” (LYNDAL) revealed a naturally occurring distribution pattern of rearranged antibody sequences, representing all known variable gene families and most functional germline sequences. To demonstrate the feasibility for selecting antibodies with therapeutic potential from these repertoires, seven LYNDAL from donors with high serum titers against herpes simplex virus (HSV) were panned on recombinant glycoprotein B of HSV-1. Screening for specific binders delivered 34 single-chain variable fragments (scFvs) with unique sequences. Sequence analysis revealed extensive somatic hypermutation of enriched clones as a result of affinity maturation. Binding of scFvs to common glycoprotein B variants from HSV-1 and HSV-2 strains was highly specific, and the majority of analyzed antibody fragments bound to the target antigen with nanomolar affinity. From eight scFvs with HSV-neutralizing capacity in vitro,the most potent antibody neutralized 50% HSV-2 at 4.5 nM as a dimeric (scFv)2. We anticipate our approach to be useful for recovering fully human antibodies with therapeutic potential.

The Role of the Endothelium in HPS Pathogenesis and Potential Therapeutic Approaches

Directory of Open Access Journals (Sweden)

Irina Gavrilovskaya

2012-01-01

Full Text Available American hantaviruses cause a highly lethal acute pulmonary edema termed hantavirus pulmonary syndrome (HPS. Hantaviruses nonlytically infect endothelial cells and cause dramatic changes in barrier functions of the endothelium without disrupting the endothelium. Instead hantaviruses cause changes in the function of infected endothelial cells that normally regulate fluid barrier functions of capillaries. The endothelium of arteries, veins, and lymphatic vessels is unique and central to the function of vast pulmonary capillary beds, which regulate pulmonary fluid accumulation. The endothelium maintains vascular barrier functions through a complex series of redundant receptors and signaling pathways that serve to both permit fluid and immune cell efflux into tissues and restrict tissue edema. Infection of the endothelium provides several mechanisms for hantaviruses to alter capillary permeability but also defines potential therapeutic targets for regulating acute pulmonary edema and HPS disease. Here we discuss interactions of HPS causing hantaviruses with the endothelium, potential endothelial cell-directed permeability mechanisms, and therapeutic targeting of the endothelium as a means of reducing the severity of HPS disease.

Therapeutic angiogenesis is an emerging paradigm for the management of ischemic pathologies. Proangiogenic Therapy is limited, however, by the current inability to deliver angiogenic factors in a sustained manner at the site of pathology. In this study, we investigated a unique nonglycosylated active fragment of hepatocyte growth factor/scatter factor, 1K1, which acts as a potent angiogenic agent in vitro and in a zebrafish embryo and a murine matrigel implant model. Furthermore, we demonstrate that nanoformulating 1K1 for sustained release temporally alters downstream signaling through the mitogen activated protein kinase pathway, and amplifies the angiogenic outcome. Merging protein engineering and nanotechnology offers exciting possibilities for the treatment of ischemic disease, and furthermore allows the selective targeting of downstream signaling pathways, which translates into discrete phenotypes.

Helping Oxytocin Deliver: Considerations in the Development of Oxytocin-Based Therapeutics for Brain Disorders.

2013-03-01

Full Text Available Concerns regarding a drought in psychopharmacology have risen from many quarters. From one perspective, the wellspring of bedrock medications for anxiety disorders, depression, and schizophrenia was serendipitously discovered over thirty year ago, the swell of pharmaceutical investment in drug discovery has receded, and the pipeline’s flow of medications with unique mechanisms of action (i.e. glutamatergic agents, CRF antagonists has slowed to a trickle. Might oxytocin (OT-based therapeutics be an oasis? Though a large basic science literature and a slowly increasing number of studies in human diseases support this hope, the bulk of extant OT studies in humans are single-dose studies on normals, and do not directly relate to improvements in human brain-based diseases. Instead, these studies have left us with a field pregnant with therapeutic possibilities, but barren of definitive treatments. In this clinically-oriented review, we discuss the extant OT literature with an eye toward helping OT deliver on its promise as a therapeutic agent. To this end, we identify ten key questions that we believe future OT research should address. From this overview, several conclusions are clear: 1 the OT system represents an extremely promising target for novel CNS drug development; 2 there is a pressing need for rigorous, randomized controlled clinical trials targeting actual patients; and 3 in order to inform the design and execution of these vital trials, we need further translational studies addressing the questions posed in this review. Looking forward, we extend a cautious hope that the next decade of OT research will birth oxytocin-targetted therapeutics that can truly deliver on this system’s therapeutic potential.

In contrast with common thought, we generated highly hydrophobic anticancer prodrug self-assembled nanoparticles without the aid of surface active substances, based on the conjugation of docetaxel to d-α-tocopherol succinate. The reduction-sensitive prodrug was synthesized with a disulfide bond inserted into the linker and was compared with a control reduction-insensitive prodrug. The morphology and stability of self-assembled nanoparticles were investigated. Cytotoxicity and apoptosis assays showed that the reduction-sensitive nanoparticles had higher anticancer activity than the reduction-insensitive nanoparticles. The reduction-sensitive nanoparticles exhibited favorable in vivo antitumor activity and tolerance compared with docetaxel Tween80-containing formulation and the reduction-insensitive nanoparticles. Taken together, the unique nanomedicine demonstrated a number of advantages: (i) ease and reproducibility of preparation, (ii) high drug payload, (iii) superior stability, (iv) prolonged circulation, and (v) improved therapeutic effect. This highly reproducible molecular assembly strategy should motivate the development of new nanomedicines. Copyright © 2016 Elsevier Inc. All rights reserved.

Rapidly proliferating leukemic progenitor cells consume substantial glucose, which may lead to glucose insufficiency in bone marrow. We show that acute myeloid leukemia (AML) cells are prone to fructose utilization with an upregulated fructose transporter GLUT5, which compensates for glucose deficiency. Notably, AML patients with upregulated transcription of the GLUT5-encoding gene SLC2A5 or increased fructose utilization have poor outcomes. Pharmacological blockage of fructose uptake ameliorates leukemic phenotypes and potentiates the cytotoxicity of the antileukemic agent, Ara-C. In conclusion, this study highlights enhanced fructose utilization as a metabolic feature of AML and a potential therapeutic target. Copyright © 2016 Elsevier Inc. All rights reserved.

Changes in unique hues induced by chromatic surrounds.

Klauke, Susanne; Wachtler, Thomas

2016-03-01

A chromatic surround can have a strong influence on the perceived hue of a stimulus. We investigated whether chromatic induction has similar effects on the perception of colors that appear pure and unmixed (unique red, green, blue, and yellow) as on other colors. Subjects performed unique hue settings of stimuli in isoluminant surrounds of different chromaticities. Compared with the settings in a neutral gray surround, unique hue settings altered systematically with chromatic surrounds. The amount of induced hue shift depended on the difference between stimulus and surround hues, and was similar for unique hue settings as for settings of nonunique hues. Intraindividual variability in unique hue settings was roughly twice as high as for settings obtained in asymmetric matching experiments, which may reflect the presence of a reference stimulus in the matching task. Variabilities were also larger with chromatic surrounds than with neutral gray surrounds, for both unique hue settings and matching of nonunique hues. The results suggest that the neural representations underlying unique hue percepts are influenced by the same neural processing mechanisms as the percepts of other colors.

The special effects of hypnosis and hypnotherapy: A contribution to an ecological model of therapeutic change.

Science.gov (United States)

Mende, Matthias

2006-04-01

There is ample evidence that hypnosis enhances the effectiveness of psychotherapy and produces some astounding effects of its own. In this paper, the effective components and principles of hypnosis and hypnotherapy are analyzed. The "special" hypnotic and hypnotherapeutic effects are linked to the fact that the ecological requirements of therapeutic change are taken into account implicitly and/or explicitly when working with hypnotic trances in a therapeutic setting. The hypnotic situation is described--theoretically and in case examples--as a therapeutic modality that gratifies and aligns the basic emotional needs to feel autonomous, related, competent, and oriented. It is shown how the hypnotic relationship can help promote a sound ecological balance between these needs--a balance that is deemed to be a necessary prerequisite for salutogenesis. Practical implications for planning hypnotherapeutic interventions are discussed.

Full Text Available Abstract Background The present study was designed to evaluate the efficacy of an internet-based therapy (Interapy for Posttraumatic Stress Disorder (PTSD in a German speaking population. Also, the quality of the online therapeutic relationship, its development and its relevance as potential moderator of the treatment effects was investigated. Method Ninety-six patients with posttraumatic stress reactions were allocated at random to ten sessions of Internet-based cognitive behavioural therapy (CBT conducted over a 5-week period or a waiting list control group. Severity of PTSD was the primary outcome. Secondary outcome variables were depression, anxiety, dissociation and physical health. Follow-up assessments were conducted at the end of treatment and 3 months after treatment. Results From baseline to post-treatment assessment, PTSD severity and other psychopathological symptoms were significantly improved for the treatment group (intent-to-treat group × time interaction effect size d = 1.40. Additionally, patients of the treatment condition showed significantly greater reduction of co-morbid depression and anxiety as compared to the waiting list condition. These effects were sustained during the 3-months follow-up period. High ratings of the therapeutic alliance and low drop-out rates indicated that a positive and stable therapeutic relationship could be established online. Significant improvement of the online working alliance in the course of treatment and a substantial correlation between the quality of the online relationship at the end of treatment and treatment outcome emerged. Conclusion Interapy proved to be a viable treatment alternative for PTSD with large effect sizes and sustained treatment effects. A stable and positive online therapeutic relationship can be established through the Internet which improved during the treatment process.

2016-02-01

Aims and method The aims of the study were to develop a scale sensitive enough to measure the interpersonal processes within a therapeutic environment, and to explore whether the new scale was sensitive enough to detect differences between settings, including a community based on compassionate mind and contextual behaviourism. The Therapeutic Environment Scales (TESS) were validated with 81 participants in three different settings: a specialist service for anxiety disorders, a specialist in-patient ward and a psychodynamic therapeutic community. Results TESS was found to be reliable and valid. Significant differences were seen between the services on the dimensions of compassion, belongingness, feeling safe, positive reinforcement of members' acts of courage, extinction and accommodation of unhelpful behaviours, inconsistency and high expressed emotion. These processes were over time associated with improved outcomes on a specialist service for anxiety disorders. Clinical implications The TESS offers a first step in exploring important interpersonal relationships in therapeutic environments and communities. An environment based on a compassionate mind and contextual behaviourism offers promise for the running of a therapeutic community.

2016-06-02

Carcinomas of the anogenital tract, in particular cervical cancer, remains one of the most common cancers in women, and represent the most frequent gynecological malignancies and the fourth leading cause of cancer death in women worldwide. Human papillomavirus (HPV)-induced lesions are immunologically distinct in that they express viral antigens, which are necessary to maintain the cancerous phenotype. The causal relationship between HPV infection and anogenital cancer has prompted substantial interest in the development of therapeutic vaccines against high-risk HPV types targeting the viral oncoproteins E6 and E7. This review will focus on the most recent clinical trials for immunotherapies for mucosal HPV-induced lesions as well as emerging therapeutic strategies that have been tested in pre-clinical models for HPV-induced diseases. Progress in peptide- and protein-based vaccines, DNA-based vaccines, viral/bacterial vector-based vaccines, immune checkpoint inhibition, immune response modifiers, and adoptive cell therapy for HPV will be discussed.

Is Life Unique?

Science.gov (United States)

Abel, David L.

2011-01-01

Is life physicochemically unique? No. Is life unique? Yes. Life manifests innumerable formalisms that cannot be generated or explained by physicodynamics alone. Life pursues thousands of biofunctional goals, not the least of which is staying alive. Neither physicodynamics, nor evolution, pursue goals. Life is largely directed by linear digital programming and by the Prescriptive Information (PI) instantiated particularly into physicodynamically indeterminate nucleotide sequencing. Epigenomic controls only compound the sophistication of these formalisms. Life employs representationalism through the use of symbol systems. Life manifests autonomy, homeostasis far from equilibrium in the harshest of environments, positive and negative feedback mechanisms, prevention and correction of its own errors, and organization of its components into Sustained Functional Systems (SFS). Chance and necessity—heat agitation and the cause-and-effect determinism of nature’s orderliness—cannot spawn formalisms such as mathematics, language, symbol systems, coding, decoding, logic, organization (not to be confused with mere self-ordering), integration of circuits, computational success, and the pursuit of functionality. All of these characteristics of life are formal, not physical. PMID:25382119

Standardized Ginkgo biloba extract EGb 761 has been shown to inhibit inflammatory hyperalgesia in rats; however, the mechanism of action is not known. This study set out to investigate the anti-inflammatory and analgesic potential of bilobalide, a unique G. biloba constituent, in three well-characterized models of acute inflammatory pain. The effect of oral, intraplantar or intrathecal administration of bilobalide or drug-vehicle (0.25% agar; 10% ethanol in H2O) on responses to noxious thermal and mechanical stimulation of the hindpaw, and paw oedema were assessed in adult male Wistar rats before and after intradermal hindpaw injection of carrageenan (3%; 50 μl) or capsaicin (10 μg; 50 μl) or after hindpaw incision (n=6-8/group). Oral administration of bilobalide (10-30 mg/kg) significantly inhibited thermal hyperalgesia in response to carrageenan, capsaicin and paw incision, independent of dose, with an efficacy similar to that of diclofenac. In the carrageenan model, mechanical hypersensitivity and paw oedema were also significantly reduced after treatment with bilobalide (10-30 mg/kg). Intrathecal administration of bilobalide (0.5-1 μg) inhibited carrageenan-induced thermal hyperalgesia, but had no effect on mechanical hypersensitivity or paw oedema (application≥2 μg induced adverse effects, precluding testing of higher doses). Intraplantar administration of bilobalide (30-100 μg) had no effect. These data show that bilobalide is a potent anti-inflammatory and antihyperalgesic agent, the therapeutic effects of which are mediated in part through a central site of action, and may account for the therapeutic action of the whole extract G. biloba.

In two studies, we demonstrated that liberals underestimate their similarity to other liberals (i.e., display truly false uniqueness), whereas moderates and conservatives overestimate their similarity to other moderates and conservatives (i.e., display truly false consensus; Studies 1 and 2). We further demonstrated that a fundamental difference between liberals and conservatives in the motivation to feel unique explains this ideological distinction in the accuracy of estimating similarity (Study 2). Implications of the accuracy of consensus estimates for mobilizing liberal and conservative political movements are discussed.

Psychological aspects of human cloning and genetic manipulation: the identity and uniqueness of human beings.

Science.gov (United States)

Morales, N M

2009-01-01

Human cloning has become one of the most controversial debates about reproduction in Western civilization. Human cloning represents asexual reproduction, but the critics of human cloning argue that the result of cloning is not a new individual who is genetically unique. There is also awareness in the scientific community, including the medical community, that human cloning and the creation of clones are inevitable. Psychology and other social sciences, together with the natural sciences, will need to find ways to help the healthcare system, to be prepared to face the new challenges introduced by the techniques of human cloning. One of those challenges is to help the healthcare system to find specific standards of behaviour that could be used to help potential parents to interact properly with cloned babies or children created through genetic manipulation. In this paper, the concepts of personality, identity and uniqueness are discussed in relationship to the contribution of twin studies in these areas. The author argues that an individual created by human cloning techniques or any other type of genetic manipulation will not show the donor's characteristics to the extent of compromising uniqueness. Therefore, claims to such an effect are needlessly alarmist.

Therapeutic Nanodevices

Therapeutic nanotechnology offers minimally invasive therapies with high densities of function concentrated in small volumes, features that may reduce patient morbidity and mortality. Unlike other areas of nanotechnology, novel physical properties associated with nanoscale dimensionality are not the raison d'être of therapeutic nanotechnology, whereas the aggregation of multiple biochemical (or comparably precise) functions into controlled nanoarchitectures is. Multifunctionality is a hallmark of emerging nanotherapeutic devices, and multifunctionality can allow nanotherapeutic devices to perform multistep work processes, with each functional component contributing to one or more nanodevice subroutine such that, in aggregate, subroutines sum to a cogent work process. Cannonical nanotherapeutic subroutines include tethering (targeting) to sites of disease, dispensing measured doses of drug (or bioactive compound), detection of residual disease after therapy and communication with an external clinician/operator. Emerging nanotherapeutics thus blur the boundaries between medical devices and traditional pharmaceuticals. Assembly of therapeutic nanodevices generally exploits either (bio)material self-assembly properties or chemoselective bioconjugation techniques, or both. Given the complexity, composition, and the necessity for their tight chemical and structural definition inherent in the nature of nanotherapeutics, their cost of goods (COGs) might exceed that of (already expensive) biologics. Early therapeutic nanodevices will likely be applied to disease states which exhibit significant unmet patient need (cancer and cardiovascular disease), while application to other disease states well-served by conventional therapy may await perfection of nanotherapeutic design and assembly protocols.

Suboptimal treatment for monoclonal antibodies (mAbs) directed against endogenous circulating soluble targets and the shed extracellular domains (ECD) of the membrane-bound targets is an important clinical concern due to the potential impact of mAbs on the in vivo efficacy and safety. Consequently, there are considerable challenges in the determination of an optimal dose and/or dosing regimen. Areas covered: This review outlines the impact of shed antigen targets from membrane-bound proteins and soluble targets on the PK and/or PD of therapeutic mAbs that have been approved in the last decade. We discuss various bioanalytical techniques that have facilitated the interpretation of the PK/PD properties of therapeutic mAbs and also considered the factors that may impact such measurements. Quantitative approaches include target-mediated PK models and bi- or tri-molecular interaction PK/PD models that describe the relationships between the antibody PK and the ensuing effects on PD biomarkers, to facilitate the mAb PK/PD characterization. Expert commentary: The proper interpretation of PK/PD relationships through the integrated PK/PD modeling and bioanalytical strategy facilitates a mechanistic understanding of the disease processes and dosing regimen optimization, thereby offering insights into developing effective therapeutic regimens. This review provides an overview of the impact of soluble targets or shed ECD on mAb PK/PD properties. We provide examples of quantitative approaches that facilitate the characterization of mAb PK/PD characteristics and their corresponding bioanalytical strategies.

Skewed Epigenetics: An Alternative Therapeutic Option for Diabetes Complications

Directory of Open Access Journals (Sweden)

Gabriele Togliatto

2015-01-01

Full Text Available Vascular complications are major causes of morbidity and mortality in type 2 diabetes patients. Mitochondrial reactive oxygen species (ROS generation and a lack of efficient antioxidant machinery, a result of hyperglycaemia, mainly contribute to this problem. Although advances in therapy have significantly reduced both morbidity and mortality in diabetic individuals, diabetes-associated vascular complications are still one of the most challenging health problems worldwide. New healing options are urgently needed as current therapeutics are failing to improve long-term outcomes. Particular effort has recently been devoted to understanding the functional relationship between chromatin structure regulation and the persistent change in gene expression which is driven by hyperglycaemia and which accounts for long-lasting diabetic complications. A detailed investigation into epigenetic chromatin modifications in type 2 diabetes is underway. This will be particularly useful in the design of mechanism-based therapeutics which interfere with long-lasting activating epigenetics and improve patient outcomes. We herein provide an overview of the most relevant mechanisms that account for hyperglycaemia-induced changes in chromatin structure; the most relevant mechanism is called “metabolic memory.”

Throughout history, patient-physician relationships have been acknowledged as an important component of the therapeutic effects of any pharmacological treatment. Here, we discuss the role of physicians' expectations in influencing the therapeutic outcomes of alcohol and drug addiction pharmacological treatments. As largely demonstrated, such expectations and attitudes may contribute to produce placebo and nocebo effects that in turn affect the course of the disease and the response to the therapy. This article is aimed at discussing the current insights into expectations, placebo and nocebo mechanisms and their impact on the therapeutic outcomes of alcohol and drug addiction treatments; with the goal of informing physicians and other health care providers about the potentially widespread implications for clinical practice and for a successful treatment regimen.

New cancer diagnostics and therapeutics from a ninth 'hallmark of cancer': symmetric self-renewal by mutated distributed stem cells.

Science.gov (United States)

Sherley, James L

2013-11-01

A total of eight cellular alterations associated with human carcinogenesis have been framed as the 'hallmarks of cancer'. This representation overlooks a ninth hallmark of cancer: the requirement for tumor-originating distributed stem cells to shift sufficiently from asymmetric to symmetric self-renewal kinetics for attainment of the high cell production rate necessary to form clinically significant tumors within a human lifespan. Overlooking this ninth hallmark costs opportunities for discovery of more selective molecular targets for development of improved cancer therapeutics and missing cancer stem cell biomarkers of greater specificity. Here, the biological basis for the ninth hallmark of cancer is considered toward highlighting its importance in human carcinogenesis and, as such, its potential for revealing unique molecules for targeting cancer diagnostics and therapeutics.

Full text: Positron emission tomography (PET) using F-18 fluorodeoxyglucose (FDG) is recognised for staging and therapeutic planning of patients with non-small cell carcinoma of the lung (NSCLC). The potential for this technique to be used in the assessment of therapeutic response has also been highlighted but may be limited by false positive results due to inflammatory response, particularly early after radiotherapy (RT). To evaluate the utility of FEX PET for therapeutic monitoring early (<12 weeks) after completion of radical RT we prospectively evaluated metabolic response and radiation toxicity using a standardised scoring system in 73 consecutive patients. All 73 had evaluable PET scans but 6 of the CT scan results were considered non-evaluable for therapeutic response using WHO criteria. PET therapeutic response category differed from that by CT in 40/67 (60%) cases and in 80% of such cases suggested a more marked response than suggested by CT (p 0.0002). Multifactor analysis including PET response, CT response, performance status, weight loss and stage revealed that PET response was the only significant predictor of survival (p 0.0001). Radiation toxicity scores were inversely related to therapeutic response on both PET (p = 0.022) and CT (p =0.029). In particular, more severe (grade 2 or 3) radiotoxicity scores on PET were associated with a greater proportion of partial or complete responses on both PET and CT than were lower (grade 0 and 1) scores (p =0.0044 and 0.041 respectively) consistent with the known relationship between the radiosensitivity of normal host and tumoral tissues. Early after completion of radiotherapy for NSCLC, PET response provides better prognostic stratification than CT response. PET can also identify typical radiation toxicity changes which are associated with response to treatment. Copyright (2002) The Australian and New Zealand Society of Nuclear Medicine Inc

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.

Family Traditions, Cultural Values, and the Clinician's Countertransference: Therapeutic Assessment of a Young Sicilian Woman.

Science.gov (United States)

Fantini, Francesca

2016-01-01

Despite recent advances in models and instruments to understand the role of a client's cultural background, clinical psychologists are not immune to implicit cultural biases that are potentially damaging to the therapeutic alliance. In this article, I present a Therapeutic Assessment with a young Sicilian woman conducted in a university-based student clinic in Italy. During the assessment, I assumed that because we were both Italians, my client shared my perspective (northern Italian) about family and individual values, which resulted in a therapeutic impasse when I responded on the basis of my individual and culturally shaped view of interpersonal and family relationships without appreciating important differences between my own and my client's microcultures. To overcome the impasse, I had to openly acknowledge such differences and reorient myself to my client's goals. I discuss the core processes involved in such a repair in the context of a cross-cultural psychological assessment.

The challenges to intimacy and sexual relationships for gay men in HIV serodiscordant relationships: a pilot study.

2001-10-01

Human Immunodeficiency Virus (HIV) infection and disease progression create imbalance in long-term, HIV-serodiscordant, gay male relationships, particularly in sexual relations and issues of physical and emotional intimacy. Stage of disease progression and worldview of the couple both affect the relationship and its survival. To redress imbalance, partners employ a range of coping strategies and techniques. This article explores these issues in the context of HIV serodiscordant gay couples and how they preserve their relationships in the face of these unique challenges. For workers who provide psychotherapeutic and community support for people with HIV and for their partners, the results of this study may be helpful in recognizing stress factors for couples, and tailoring support services to the needs of both partners. Overall, this study provides a basis for further work examining the dynamics of serodiscordant relationships.

Josiah Willock, Robina; Miller, Joseph B; Mohyi, Michelle; Abuzaanona, Ahmed; Muminovic, Meri; Levy, Phillip D

2018-01-29

This review aims to emphasize how therapeutic inertia, the failure of clinicians to intensify treatment when blood pressure rises or remains above therapeutic goals, contributes to suboptimal blood pressure control in hypertensive populations. Studies reveal that the therapeutic inertia is quite common and contributes to suboptimal blood pressure control. Quality improvement programs and standardized approaches to support antihypertensive treatment intensification are ways to combat therapeutic inertia. Furthermore, programs that utilize non-physician medical professionals such as pharmacists and nurses demonstrate promise in mitigating the effects of this important problem. Therapeutic inertia impedes antihypertensive management and requires a broad effort to reduce its effects. There is an ongoing need for renewed focus and research in this area to improve hypertension control.

Aims To synthesize evidence and knowledge from published research about nurses' experiences of nurse-patient relationships with adult patients in general, acute inpatient hospital settings. Background While primary research on nurses' experiences has been reported, it has not been previously synthesized. Design Meta-ethnography. Data sources Published literature from Australia, Europe, and North America, written in English between January 1999–October 2009 was identified from databases: CINAHL, Medline, British Nursing Index and PsycINFO. Review methods Qualitative studies describing nurses' experiences of the nurse-patient relationship in acute hospital settings were reviewed and synthesized using the meta-ethnographic method. Results Sixteen primary studies (18 papers) were appraised as high quality and met the inclusion criteria. The findings show that while nurses aspire to develop therapeutic relationships with patients, the organizational setting at a unit level is strongly associated with nurses' capacity to build and sustain these relationships. The organizational conditions of critical care settings appear best suited to forming therapeutic relationships, while nurses working on general wards are more likely to report moral distress resulting from delivering unsatisfactory care. General ward nurses can then withdraw from attempting to emotionally engage with patients. Conclusion The findings of this meta-ethnography draw together the evidence from several qualitative studies and articulate how the organizational setting at a unit level can strongly influence nurses' capacity to build and sustain therapeutic relationships with patients. Service improvements need to focus on how to optimize the organizational conditions that support nurses in their relational work with patients. PMID:23163719

Cooperative nanomaterials systems for cancer diagnosis and therapeutics

Science.gov (United States)

Park, Ji Ho

The unique electromagnetic and biologic properties of nanomaterials are being harnessed to build powerful new medical technologies. Particularly, there have been recently increasing interests in cancer nanotechnology, wherein nanomaterials play an important role in ultrasensitive imaging, targeting, and therapy of cancer. However, these nanomaterials typically function as individual units and are designed to independently perform their tasks. In this dissertation, new cooperative nanosystems consisting of two distinct nanomaterials that work together to target, identify, or treat tumors in vivo were studied. In the first two chapters, the synthesis of worm-shaped dextran-coated iron oxide nanoparticles (nanoworms, NW) exhibiting substantial in vivo circulation times and significant tumor targeting when coated with tumor-homing peptides were studied. NWs are also found to display a greater magnetic resonance (MR) response than the spherical nanoparticles. Next, two types of multifunctional nanoparticles were fabricated for simultaneous detection and treatment of cancer. Micellar hybrid nanoparticles (MHN) that contain magnetic nanoparticles, quantum dots, and an anti-cancer drug doxorubicin (DOX) within a single PEG-modified phospholipid micelle were first prepared. Simultaneous multimodal imaging (MR and fluorescence) and targeted drug delivery in vitro and in vivo was performed using DOX-incorporated targeted MHN. Secondly, luminescent porous silicon nanoparticles (LPSINP) that were drug-loadable, biodegradable and relatively non-toxic were prepared. In contrast to most inorganic nanomaterials, LPSINP were degraded in vivo in a relatively short time with no noticeable toxicity. The clearance and degradation of intravenously injected LPSINP in the bladder, liver, and spleen were established by whole-body fluorescence imaging. Finally, two types of cooperative nanomaterials systems to amplify targeting and deliver drugs efficiently to regions of tumor invasion were

2014-10-01

This study examined associations among family environment, coping, and emotional and conduct problems in adolescents attending therapeutic day schools due to mental health problems. Adolescents (N = 417; 30.2% female) ages 13-20 (M = 15.25) reported on their family environment (affective involvement and functioning), coping (emotion-focused support-seeking, cognitive restructuring, avoidant actions), and emotional and conduct problems. Poorer family environment was associated with less emotion-focused support-seeking and cognitive restructuring, and more emotional and conduct problems. Emotional problems were negatively associated with cognitive restructuring, and conduct problems were negatively associated with all coping strategies. Cognitive restructuring accounted for the relationship between family environment and emotional problems. Cognitive restructuring and emotion-focused support-seeking each partially accounted for the relationship between family functioning and conduct problems, but not the relationship between family affective involvement and conduct problems. Findings implicate the role of coping in the relationship between family environment and adolescent mental health. Copyright © 2014 The Foundation for Professionals in Services for Adolescents.

Oxidative Stress and Liver Cancer: Etiology and Therapeutic Targets

Directory of Open Access Journals (Sweden)

Zhanpeng Wang

2016-01-01

Full Text Available Accumulating evidence has indicated that oxidative stress (OS is associated with the development of hepatocellular carcinoma (HCC. However, the mechanisms remain largely unknown. Normally, OS occurs when the body receives any danger signal—from either an internal or external source—and further induces DNA oxidative damage and abnormal protein expression, placing the body into a state of vulnerability to the development of various diseases such as cancer. There are many factors involved in liver carcinogenesis, including hepatitis B virus (HBV and hepatitis C virus (HCV infection, alcohol abuse, and nonalcoholic fatty liver disease (NAFLD. The relationship between OS and HCC has recently been attracting increasing attention. Therefore, elucidation of the impact of OS on the development of liver carcinogenesis is very important for the prevention and treatment of liver cancer. This review focuses mainly on the relationship between OS and the development of HCC from the perspective of cellular and molecular mechanisms and the etiology and therapeutic targets of HCC.

Tiggemann, Marika; Hopkins, Louise A

2011-06-01

The study aimed to investigate the motivations underlying the body modification practices of tattooing and piercing. There were 80 participants recruited from an Australian music store, who provided descriptions of their tattoos and piercings and completed measures of need for uniqueness, appearance investment and distinctive appearance investment. It was found that tattooed individuals scored significantly higher on need for uniqueness than non-tattooed individuals. Further, individuals with conventional ear piercings scored significantly lower on need for uniqueness than individuals with no piercings or with facial and body piercings. Neither appearance investment nor distinctive appearance investment differed significantly among tattoo or piercing status groups. Strength of identification with music was significantly correlated with number of tattoos, but not number of piercings. It was concluded that tattooing, but not body piercing, represents a bodily expression of uniqueness. Copyright © 2011 Elsevier Ltd. All rights reserved.

Respiratory virus modulation of host nucleocytoplasmic transport; target for therapeutic intervention?

Directory of Open Access Journals (Sweden)

Leon eCaly

2015-08-01

Full Text Available The respiratory diseases caused by Rhinovirus, Respiratory Syncytial Virus and Influenza virus represent a large social and financial burden on healthcare worldwide. Although all three viruses have distinctly unique properties in terms of infection and replication, they share the ability to exploit/manipulate the host-cell nucleocytoplasmic transport system in order to replicate effectively and efficiently. This review outlines the various ways in which infection by these viruses impacts on the host nucleocytoplasmic transport system, and examples where inhibition thereof in turn decreases viral replication. The highly conserved nature of the nucleocytoplasmic transport system and the viral proteins that interact with it make this virus-host interface a prime candidate for the development of specific antiviral therapeutics in the future.

Cone photoreceptor sensitivities and unique hue chromatic responses: correlation and causation imply the physiological basis of unique hues.

Science.gov (United States)

Pridmore, Ralph W

2013-01-01

This paper relates major functions at the start and end of the color vision process. The process starts with three cone photoreceptors transducing light into electrical responses. Cone sensitivities were once expected to be Red Green Blue color matching functions (to mix colors) but microspectrometry proved otherwise: they instead peak in yellowish, greenish, and blueish hues. These physiological functions are an enigma, unmatched with any set of psychophysical (behavioral) functions. The end-result of the visual process is color sensation, whose essential percepts are unique (or pure) hues red, yellow, green, blue. Unique hues cannot be described by other hues, but can describe all other hues, e.g., that hue is reddish-blue. They are carried by four opponent chromatic response curves but the literature does not specify whether each curve represents a range of hues or only one hue (a unique) over its wavelength range. Here the latter is demonstrated, confirming that opponent chromatic responses define, and may be termed, unique hue chromatic responses. These psychophysical functions also are an enigma, unmatched with any physiological functions or basis. Here both enigmas are solved by demonstrating the three cone sensitivity curves and the three spectral chromatic response curves are almost identical sets (Pearson correlation coefficients r from 0.95-1.0) in peak wavelengths, curve shapes, math functions, and curve crossover wavelengths, though previously unrecognized due to presentation of curves in different formats, e.g., log, linear. (Red chromatic response curve is largely nonspectral and thus derives from two cones.) Close correlation combined with deterministic causation implies cones are the physiological basis of unique hues. This match of three physiological and three psychophysical functions is unique in color vision.

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.

Employing the therapeutic operating characteristic (TOC) graph for individualised dose prescription.

Hoffmann, Aswin L; Huizenga, Henk; Kaanders, Johannes H A M

2013-03-07

In current practice, patients scheduled for radiotherapy are treated according to 'rigid' protocols with predefined dose prescriptions that do not consider risk-taking preferences of individuals. The therapeutic operating characteristic (TOC) graph is applied as a decision-aid to assess the trade-off between treatment benefit and morbidity to facilitate dose prescription customisation. Historical dose-response data from prostate cancer patient cohorts treated with 3D-conformal radiotherapy is used to construct TOC graphs. Next, intensity-modulated (IMRT) plans are generated by optimisation based on dosimetric criteria and dose-response relationships. TOC graphs are constructed for dose-scaling of the optimised IMRT plan and individualised dose prescription. The area under the TOC curve (AUC) is estimated to measure the therapeutic power of these plans. On a continuous scale, the TOC graph directly visualises treatment benefit and morbidity risk of physicians' or patients' choices for dose (de-)escalation. The trade-off between these probabilities facilitates the selection of an individualised dose prescription.

In current practice, patients scheduled for radiotherapy are treated according to ‘rigid’ protocols with predefined dose prescriptions that do not consider risk-taking preferences of individuals. The therapeutic operating characteristic (TOC) graph is applied as a decision-aid to assess the trade-off between treatment benefit and morbidity to facilitate dose prescription customisation. Historical dose-response data from prostate cancer patient cohorts treated with 3D-conformal radiotherapy is used to construct TOC graphs. Next, intensity-modulated (IMRT) plans are generated by optimisation based on dosimetric criteria and dose-response relationships. TOC graphs are constructed for dose-scaling of the optimised IMRT plan and individualised dose prescription. The area under the TOC curve (AUC) is estimated to measure the therapeutic power of these plans. On a continuous scale, the TOC graph directly visualises treatment benefit and morbidity risk of physicians’ or patients’ choices for dose (de-)escalation. The trade-off between these probabilities facilitates the selection of an individualised dose prescription. TOC graphs show broader therapeutic window and higher AUCs with increasing target dose heterogeneity. The TOC graph gives patients and physicians access to a decision-aid and read-out of the trade-off between treatment benefit and morbidity risks for individualised dose prescription customisation over a continuous range of dose levels

The availability of multiple disease-modifying medications with regulatory approval to treat multiple sclerosis illustrates the substantial progress made in therapy of the disease. However, all are only partially effective in preventing inflammatory tissue damage in the central nervous system and none directly promotes repair. Cell-based therapies, including immunoablation followed by autologous haematopoietic stem cell transplantation, mesenchymal and related stem cell transplantation, pharmacologic manipulation of endogenous stem cells to enhance their reparative capabilities, and transplantation of oligodendrocyte progenitor cells, have generated substantial interest as novel therapeutic strategies for immune modulation, neuroprotection, or repair of the damaged central nervous system in multiple sclerosis. Each approach has potential advantages but also safety concerns and unresolved questions. Moreover, clinical trials of cell-based therapies present several unique methodological and ethical issues. We summarize here the status of cell-based therapies to treat multiple sclerosis and make consensus recommendations for future research and clinical trials. © The Author (2017).

Relationships between peers are often considered central to the therapeutic process, yet there is relatively little empirical research either on the nature of peer-to-peer relationships within residential treatment or on how those relationships generate positive behaviour change or facilitate recovery. In this paper, we explore relationships between peers in residential addiction treatment, drawing upon the concept of social capital to frame our analyses. Our study was undertaken during 2015 and 2016 in two English residential treatment services using the same therapeutic community-informed model of treatment. We conducted 22 in-depth interviews with 13 current and 9 former service residents. All interviews were audio-recorded, transcribed verbatim, coded in MAXQDA, and analysed using Iterative Categorisation. Residents reported difficult relationship histories and limited social networks on entry into treatment. Once in treatment, few residents described bonding with their peers on the basis of shared experiences and lifestyles. Instead, interpersonal differences polarised residents in ways that undermined their social capital further. Some senior peers who had been in residential treatment longer acted as positive role models, but many modelled negative behaviours that undermined others' commitment to treatment. Relationships between peers could generate feelings of comfort and connectedness, and friendships developed when residents found things in common with each other. However, residents more often reported isolation, loneliness, wariness, bullying, manipulation, intimidation, social distancing, tensions and conflict. Overall, relationships between peers within residential treatment seemed to generate some positive but more negative social capital; undermining the notion of the community as a method of positive behaviour change. With the caveat that our data have limitations and further research is needed, we suggest that residential treatment providers should

Therapeutic monoclonal antibody N-glycosylation - Structure, function and therapeutic potential.

Cymer, Florian; Beck, Hermann; Rohde, Adelheid; Reusch, Dietmar

Therapeutic antibodies (IgG-type) contain several post-translational modifications (PTMs) whereby introducing a large heterogeneity, both structural and functional, into this class of therapeutics. Of these modifications, glycosylation in the fragment crystallizable (Fc) region is the most heterogeneous PTM, which can affect the stability of the molecule and interactions with Fc-receptors in vivo. Hence, the glycoform distribution can affect the mode of action and have implications for bioactivity, safety and efficacy of the drug. Main topics of the manuscript include: What factors influence the (Fc) glycan pattern in therapeutic antibodies and how can these glycans be characterized? How does structure of the Fc-glycan relate to function and what methods are available to characterize those functions? Although heterogeneous in their scope, the different sections are intended to combine current knowledge on structure-function correlations of IgG glycan structures with regard to Fc (effector) functions, as well as basic aspects and methodologies for their assessment.

Assessing the role of relationship conflict in sexual dysfunction.

Science.gov (United States)

Metz, Michael E; Epstein, Norman

2002-01-01

Relationship conflict has long been thought to cause, maintain, and influence the therapeutic outcome of sexual problems in the absence of a physical cause. The results of conflict can influence partners' relationship satisfaction, and relationship satisfaction can influence sexual satisfaction. General relationship deficiencies, such as unresolved conflict, undermine the mutual acceptance that is important to healthy sexual functioning. The purpose of this article is to summarize some of the basic empirical findings of studies of conflict patterns in relationships and their role in sex dysfunction and to suggest a model for assessing relationship conflict as a feature of sexual dysfunction. Results from several studies indicate that couples with sexual problems may have conflict-management issues and employ distinct conflict-resolution styles compared to satisfied couples. Dysfunctional conflict resolution may be a cause or result of some sexual problems, whereas constructive interaction concerning conflict can add to emotional and sexual intimacy in a couple's relationship. These patterns warrant systematic attention in assessment and intervention in sex therapy.

Translational nanomedicine--through the therapeutic window.

Science.gov (United States)

Pierce, Robin L

2015-01-01

Translational nanomedicine occurs only through the successful integration of multiple inputs and iterative modifications. The therapeutic window plays a pivotal role in the trajectory of translational nanomedicine. Often defined in terms of the range of dosage for safe and effective therapeutic effect, a second definition of the therapeutic window refers to the often narrow temporal window in which a therapeutic effect can be obtained. Expanding the second definition to explicitly include the spatial dimension, this article explores aspects of the therapeutic spaces created by nanomedicine that shift the traditional dimensions of symptom, sign and pathology. This article analyzes three aspects of the therapeutic window in nanomedicine - temporal, spatial and manner of construction and their impact on the dimensions of modern medicine.

Uniqueness conditions for finitely dependent random fields

International Nuclear Information System (INIS)

Dobrushin, R.L.; Pecherski, E.A.

1981-01-01

The authors consider a random field for which uniqueness and some additional conditions guaranteeing that the correlations between the variables of the field decrease rapidly enough with the distance between the values of the parameter occur. The main result of the paper states that in such a case uniqueness is true for any other field with transition probabilities sufficiently close to those of the original field. Then they apply this result to some ''degenerate'' classes of random fields for which one can check this condition of correlation to decay, and thus obtain some new conditions of uniqueness. (Auth.)

Cancer is a problem of global importance, since the incidence is increasing worldwide and therapeutic options are generally limited. Thus, it becomes imperative to find new therapeutic targets as well as new molecules with therapeutic potential for tumors. Flavonoids are polyphenolic compounds that may be potential therapeutic agents. Several studies have shown that these compounds have a higher anticancer potential. Among the flavonoids in the human diet, quercetin is one of the most important. In the last decades, several anticancer properties of quercetin have been described, such as cell signaling, pro-apoptotic, anti-proliferative and anti-oxidant effects, growth suppression. In fact, it is now well known that quercetin has diverse biological effects, inhibiting multiple enzymes involved in cell proliferation, as well as, in signal transduction pathways. On the other hand, there are also studies reporting potential synergistic effects when combined quercetin with chemotherapeutic agents or radiotherapy. In fact, several studies which aim to explore the anticancer potential of these combined treatments have already been published, the majority with promising results. Actually it is well known that quercetin can act on the chemosensitization and radiosensitization but also as chemoprotective and radioprotective, protecting normal cells of the side effects that results from chemotherapy and radiotherapy, which obviously provides notable advantages in their use in anticancer treatment. Thus, all these data indicate that quercetin may have a key role in anticancer treatment. In this context, this review is focused on the relationship between flavonoids and cancer, with special emphasis on the role of quercetin.

Cone photoreceptor sensitivities and unique hue chromatic responses: correlation and causation imply the physiological basis of unique hues.

Directory of Open Access Journals (Sweden)

Ralph W Pridmore

Full Text Available This paper relates major functions at the start and end of the color vision process. The process starts with three cone photoreceptors transducing light into electrical responses. Cone sensitivities were once expected to be Red Green Blue color matching functions (to mix colors but microspectrometry proved otherwise: they instead peak in yellowish, greenish, and blueish hues. These physiological functions are an enigma, unmatched with any set of psychophysical (behavioral functions. The end-result of the visual process is color sensation, whose essential percepts are unique (or pure hues red, yellow, green, blue. Unique hues cannot be described by other hues, but can describe all other hues, e.g., that hue is reddish-blue. They are carried by four opponent chromatic response curves but the literature does not specify whether each curve represents a range of hues or only one hue (a unique over its wavelength range. Here the latter is demonstrated, confirming that opponent chromatic responses define, and may be termed, unique hue chromatic responses. These psychophysical functions also are an enigma, unmatched with any physiological functions or basis. Here both enigmas are solved by demonstrating the three cone sensitivity curves and the three spectral chromatic response curves are almost identical sets (Pearson correlation coefficients r from 0.95-1.0 in peak wavelengths, curve shapes, math functions, and curve crossover wavelengths, though previously unrecognized due to presentation of curves in different formats, e.g., log, linear. (Red chromatic response curve is largely nonspectral and thus derives from two cones. Close correlation combined with deterministic causation implies cones are the physiological basis of unique hues. This match of three physiological and three psychophysical functions is unique in color vision.

Practical relevance of pattern uniqueness in forensic science.

Science.gov (United States)

Jayaprakash, Paul T

2013-09-10

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.

The role of need fulfillment in relationship functioning and well-being: a self-determination theory perspective.

Science.gov (United States)

Patrick, Heather; Knee, C Raymond; Canevello, Amy; Lonsbary, Cynthia

2007-03-01

Self-determination theory posits 3 basic psychological needs: autonomy (feeling uncoerced in one's actions), competence (feeling capable), and relatedness (feeling connected to others). Optimal well-being results when these needs are satisfied, though this research has traditionally focused on individual well-being outcomes (e.g., E. L. Deci & R. M. Ryan, 2000). Three studies examined the role of need fulfillment in relationship functioning and well-being. Study 1 found that fulfillment of each need individually predicted both individual and relationship well-being, with relatedness being the strongest unique predictor of relationship outcomes. Study 2 found that both partners' need fulfillment uniquely predicted one's own relationship functioning and well-being. Finally, in Study 3, the authors used a diary recording procedure and tested a model in which the association between need fulfillment and relationship quality was mediated by relationship motivation. Those who experienced greater need fulfillment enjoyed better postdisagreement relationship quality primarily because of their tendency to have more intrinsic or autonomous reasons for being in their relationship. 2007 APA, all rights reserved

Relationships among alexithymia, therapeutic alliance, and psychotherapy outcome in major depressive disorder.

Science.gov (United States)

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

2017-08-01

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.

Lawton, Michelle; Haddock, Gillian; Conroy, Paul; Sage, Karen

2016-11-01

To synthesize qualitative studies exploring patients' and professionals' perspectives and experiences of developing and maintaining therapeutic alliances in stroke rehabilitation. A systematic literature search was conducted using the following electronic databases: PsycINFO, CINAHL, Embase, MEDLINE, Allied and Complementary Medicine Database, Applied Social Sciences Index and Abstracts, and ComDisDome from inception to May 2014. This was supplemented by hand searching, reference tracking, generic web searching, and e-mail contact with experts. Qualitative peer reviewed articles reporting experiences or perceptions of the patient or professional in relation to therapeutic alliance construction and maintenance in stroke rehabilitation were selected for inclusion. After a process of exclusion, 17 publications were included in the synthesis. All text identified in the results and discussion sections of the selected studies were extracted verbatim for analysis in a qualitative software program. Studies were critically appraised independently by 2 reviewers. Articles were synthesized using a technique of meta-ethnography. Four overarching themes emerged from the process of reciprocal translation: (1) the professional-patient relationship: degree of connectedness; (2) asymmetrical contributions; (3) the process of collaboration: finding the middle ground; and (4) system drivers. The findings from the meta-ethnography suggest that the balance of power between the patient and professional is asymmetrically distributed in the construction of the alliance. However, given that none of the studies included in the review addressed therapeutic alliance as a primary research area, further research is required to develop a conceptual framework relevant to stroke rehabilitation, in order to determine how this construct contributes to treatment efficacy.

ADHD and Present Hedonism: time perspective as a potential diagnostic and therapeutic tool.

Science.gov (United States)

Weissenberger, S; Klicperova-Baker, M; Zimbardo, P; Schonova, K; Akotia, D; Kostal, J; Goetz, M; Raboch, J; Ptacek, R

2016-01-01

The article draws primarily from the behavioral findings (mainly psychiatric and psychological observations) and points out the important relationships between attention-deficit/hyperactivity disorder (ADHD) symptoms and time orientation. Specifically, the authors argue that there is a significant overlap between the symptoms of ADHD and Present Hedonism. Present Hedonism is defined by Zimbardo's time perspective theory and assessed by Zimbardo Time Perspective Inventory. Developmental data on Present Hedonism of males and females in the Czech population sample (N=2201) are also presented. The hypothesis of relationship between ADHD and Present Hedonism is mainly derived from the prevalence of addictive behavior (mainly excessive Internet use, alcohol abuse, craving for sweets, fatty foods, and fast foods), deficits in social learning, and increased aggressiveness both in ADHD and in the population scoring high on Present Hedonism in the Zimbardo Time Perspective Inventory. We conclude that Zimbardo's time perspective offers both: 1) a potential diagnostic tool - the Zimbardo Time Perspective Inventory, particularly its Present Hedonism scale, and 2) a promising preventive and/or therapeutic approach by the Time Perspective Therapy. Time Perspective Therapy has so far been used mainly to treat past negative trauma (most notably, posttraumatic stress disorder); however, it also has value as a potential therapeutic tool for possible behavioral compensation of ADHD.

[Health security--GMOs in therapeutics].

Science.gov (United States)

Trouvin, J-H

2003-03-01

The recent progress in human therapeutics has been made possible thanks to molecular biology and its use in producing proteins having the same sequence and structure as that of human proteins. The use of GMOs allows production of proteins with high added value in therapeutics, which are of satisfactory quality. GMOs may also be directly administered to patients as gene therapy vectors. However, the use of GMOs in therapeutics must take into consideration some risks, particularly those of microbiological contamination, of neo-antigenicity as well as environmental risks with regard to the way of use of the GMO. Nevertheless, those risks are taken in due consideration in the development of these new medicinal products; solutions have been found to allow their use in therapeutics with a very positive benefit/risk ratio. Medicinal products from biotechnology have enabled considerable therapeutic progress without compromising health security.

Therapeutic cloning: The ethical limits

A brief outline of stem cells, stem cell therapy and therapeutic cloning is given. The position of therapeutic cloning with regard to other embryonic manipulations - IVF-based reproduction, embryonic stem formation from IVF embryos and reproductive cloning - is indicated. The main ethically challenging stages in therapeutic cloning are considered to be the nuclear transfer process including the source of eggs for this and the destruction of an embryo to provide stem cells for therapeutic use. The extremely polarised nature of the debate regarding the status of an early human embryo is noted, and some potential alternative strategies for preparing immunocompatible pluripotent stem cells are indicated

Therapeutic cloning in the mouse

Science.gov (United States)

Mombaerts, Peter

2003-01-01

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

Human uniqueness-self-interest and social cooperation.

Science.gov (United States)

Okada, Daijiro; Bingham, Paul M

2008-07-21

Humans are unique among all species of terrestrial history in both ecological dominance and individual properties. Many, or perhaps all, of the unique elements of this nonpareil status can be plausibly interpreted as evolutionary and strategic elements and consequences of the unprecedented intensity and scale of our social cooperation. Convincing explanation of this unique human social adaptation remains a central, unmet challenge to the scientific enterprise. We develop a hypothesis for the ancestral origin of expanded cooperative social behavior. Specifically, we present a game theoretic analysis demonstrating that a specific pattern of expanded social cooperation between conspecific individuals with conflicts of interest (including non-kin) can be strategically viable, but only in animals that possess a highly unusual capacity for conspecific violence (credible threat) having very specific properties that dramatically reduce the costs of coercive violence. The resulting reduced costs allow preemptive or compensated coercion to be an instantaneously self-interested behavior under diverse circumstances rather than in rare, idiosyncratic circumstances as in actors (animals) who do not have access to inexpensive coercive threat. Humans are apparently unique among terrestrial organisms in having evolved conspecific coercive capabilities that fulfill these stringent requirements. Thus, our results support the proposal that access to a novel capacity for projection of coercive threat might represent the essential initiating event for the evolution of a human-like pattern of social cooperation and the subsequent evolution of the diverse features of human uniqueness. Empirical evidence indicates that these constraints were, in fact, met only in our evolutionary lineage. The logic for the emergence of uniquely human cooperation suggested by our analysis apparently accounts simply for the human fossil record.

The relationship between therapeutic alliance and patient's suicidal thoughts, self-harming behaviours and suicide attempts: A systematic review.

Science.gov (United States)

Dunster-Page, Charlotte; Haddock, Gillian; Wainwright, Laura; Berry, Katherine

2017-12-01

Suicidality is a common concern for people with mental health problems. The interpersonal nature of suicidality suggests that therapeutic alliance may be important when working clinically with suicidal patients. This paper is a systematic review of studies investigating the association between alliance and treatment outcome relating to suicidal ideation and behaviours. Systematic searches of PsychINFO, MEDLINE, AMED, EMBASE, Web of Science and CINAHL were completed using words that captured the concepts of alliance and suicidality. Eligible studies: involved participants aged 18-years-old or over; used a validated measure of therapeutic alliance; and reported associations between alliance and suicidality. Abstracts, qualitative studies and articles not written in English were excluded. Twelve studies were included. Findings indicated that alliance is associated with suicidality. Alliance was related to suicidality in eleven of the papers. Self-harming behaviours had the strongest association with patient-rated alliance. Suicide attempts had the weakest association, possibly due to the infrequency of suicide attempts in the studies reviewed. The twelve studies were heterogeneous in terms of the measure of alliance used, method of assessing suicidality, clinical setting and professional-type. This variability limited the degree to which findings could be synthesised. Therapists, care-coordinators and mental health teams should recognise the importance of building a strong therapeutic alliance with suicidal patients. Researchers should use consistent methods of measuring alliance and assessing suicidality in future studies. Clinicians and researchers should note that suicidal thoughts, self-harm and suicide attempts may be related to alliance in different ways and therefore should be assessed as separate constructs.

Maca polysaccharides, some of the major bioactive substances in Lepidium meyenii (Walp.) (Maca), have various biological properties, including anti-oxidant, anti-fatigue, anti-tumor, and immunomodulatory effects, as well as hepatoprotective activity and regulation function. Although many therapeutics depend on multiple structures of maca polysaccharides in addition to providing sufficient foundations for maca polysaccharide products in industrial applications, the relationships between the pharmacological effects and structures have not been established. Therefore, this article summarizes the extraction and purification methods, compositions, pharmacological effects, prospects and industrial applications of maca polysaccharides.

Homeopathy and systematics: a systematic analysis of the therapeutic effects of the plant species used in homeopathy.

Science.gov (United States)

Bharatan, V

2008-07-01

The therapeutic effects of the plant species used in homeopathy have never been subjected to systematic analysis. A survey of the various Materiae Medicae shows that over 800 plant species are the source of medicines in homeopathy. As these medicines are considered related to one another with respect to their therapeutic effects for treating similar symptoms, the aim is to classify and map them using the concept of homology. This involves placing the discipline of homeopathy into a comparative framework using these plant medicines as taxa, therapeutic effects as characters, and contemporary cladistic techniques to analyse these relationships. The results are compared using cladograms based on different data sets used in biology (e.g. morphological characters and DNA sequences) to test whether similar cladistic patterns exist among these medicines. By classifying the therapeutic actions, genuine homologies can be distinguished from homoplasies. As this is a comparative study it has been necessary first to update the existing nomenclature of the plant species in the homeopathic literature in line with the current International Code of Botanical Nomenclature.

Achieving the Promise of Therapeutic Extracellular Vesicles: The Devil is in Details of Therapeutic Loading.

Science.gov (United States)

Sutaria, Dhruvitkumar S; Badawi, Mohamed; Phelps, Mitch A; Schmittgen, Thomas D

2017-05-01

Extracellular vesicles (EVs) represent a class of cell secreted organelles which naturally contain biomolecular cargo such as miRNA, mRNA and proteins. EVs mediate intercellular communication, enabling the transfer of functional nucleic acids from the cell of origin to the recipient cells. In addition, EVs make an attractive delivery vehicle for therapeutics owing to their increased stability in circulation, biocompatibility, low immunogenicity and toxicity profiles. EVs can also be engineered to display targeting moieties on their surfaces which enables targeting to desired tissues, organs or cells. While much has been learned on the role of EVs as cell communicators, the field of therapeutic EV application is currently under development. Critical to the future success of EV delivery system is the description of methods by which therapeutics can be successfully and efficiently loaded within the EVs. Two methods of loading of EVs with therapeutic cargo exist, endogenous and exogenous loading. We have therefore focused this review on describing the various published approaches for loading EVs with therapeutics.

Using Quantum Confinement to Uniquely Identify Devices

Modern technology unintentionally provides resources that enable the trust of everyday interactions to be undermined. Some authentication schemes address this issue using devices that give a unique output in response to a challenge. These signatures are generated by hard-to-predict physical responses derived from structural characteristics, which lend themselves to two different architectures, known as unique objects (UNOs) and physically unclonable functions (PUFs). The classical design of UNOs and PUFs limits their size and, in some cases, their security. Here we show that quantum confinement lends itself to the provision of unique identities at the nanoscale, by using fluctuations in tunnelling measurements through quantum wells in resonant tunnelling diodes (RTDs). This provides an uncomplicated measurement of identity without conventional resource limitations whilst providing robust security. The confined energy levels are highly sensitive to the specific nanostructure within each RTD, resulting in a distinct tunnelling spectrum for every device, as they contain a unique and unpredictable structure that is presently impossible to clone. This new class of authentication device operates with minimal resources in simple electronic structures above room temperature.

An approach for ascertaining whether a signal is uniquely determined by its Fourier transform phase is proposed. It is shown that uniqueness corresponds to the nonsingularity of a matrix which can be formed from the finite-length real sequence. The criterion of uniqueness for reconstructing a

Reactor-produced therapeutic radioisotopes

Knapp, F.F. Jr.

2002-01-01

The significant worldwide increase in therapeutic radioisotope applications in nuclear medicine, oncology and interventional cardiology requires the dependable production of sufficient levels of radioisotopes for these applications (Reba, 2000; J. Nucl. Med., 1998; Nuclear News, 1999; Adelstein and Manning, 1994). The issues associated with both accelerator- and reactor-production of therapeutic radioisotopes is important. Clinical applications of therapeutic radioisotopes include the use of both sealed sources and unsealed radiopharmaceutical sources. Targeted radiopharmaceutical agents include those for cancer therapy and palliation of bone pain from metastatic disease, ablation of bone marrow prior to stem cell transplantation, treatment modalities for mono and oligo- and polyarthritis, for cancer therapy (including brachytherapy) and for the inhibition of the hyperplastic response following coronary angioplasty and other interventional procedures (For example, see Volkert and Hoffman, 1999). Sealed sources involve the use of radiolabeled devices for cancer therapy (brachytherapy) and also for the inhibition of the hyperplasia which is often encountered after angioplasty, especially with the exponential increase in the use of coronary stents and stents for the peripheral vasculature and other anatomical applications. Since neutron-rich radioisotopes often decay by beta decay or decay to beta-emitting daughter radioisotopes which serve as the basis for radionuclide generator systems, reactors are expected to play an increasingly important role for the production of a large variety of therapeutic radioisotopes required for these and other developing therapeutic applications. Because of the importance of the availability of reactor-produced radioisotopes for these applications, an understanding of the contribution of neutron spectra for radioisotope production and determination of those cross sections which have not yet been established is important.

2015-08-01

To design and select the next generation of ocular therapeutics, we performed a comprehensive ocular and systemic pharmacokinetic (PK) analysis of a variety of antibodies and antibody fragments, including a novel-designed bispecific antibody. Molecules were administrated via intravitreal (IVT) or intravenous (IV) injections in rabbits, and antibody concentrations in each tissue were determined by ELISA. A novel mathematical model was developed to quantitate the structure-PK relationship. After IVT injection, differences in vitreal half-life observed across all molecules ranged between 3.2 and 5.2 days. Modification or elimination of the fragment crystallizable (Fc) region reduced serum half-life from 9 days for the IgG to 5 days for the neonatal Fc receptor (FcRn) null mAb, to 3.1 to 3.4 days for the other formats. The F(ab')2 was the optimal format for ocular therapeutics with comparable vitreal half-life to full-length antibodies, but with minimized systemic exposure. Concomitantly, the consistency among mathematical model predictions and observed data validated the model for future PK predictions. In addition, we showed a novel design to develop bispecific antibodies, here with activity targeting multiple angiogenesis pathways. We demonstrated that protein molecular weight and Fc region do not play a critical role in ocular PK, as they do systemically. Moreover, the mathematical model supports the selection of the "ideal therapeutic" by predicting ocular and systemic PK of any antibody format for any dose regimen. These findings have important implications for the design and selection of ocular therapeutics according to treatment needs, such as maximizing ocular half-life and minimizing systemic exposure.

2018-07-01

Spinal Cord Injury (SCI) patients face unique identity challenges associated with physical limitations, higher comorbid depression, increased suicidality and reduced subjective well-being. Post-injury identity is often unaddressed in subacute rehabilitation environments where critical physical and functional rehabilitation goals are prioritized. Therapeutic songwriting has demonstrated prior efficacy in promoting healthy adjustment and as a means of expression for post-injury narratives. The current study sought to examine the identity narratives of therapeutic songwriting participants. Case-series analysis of the individual identity trajectories of eight individuals. Subacute rehabilitation facility, Victoria, Australia. Eight individuals with an SCI; 7 males and 1 female. Six-week therapeutic songwriting intervention facilitated by a music therapist to promote identity rehabilitation. Identity, subjective well-being and distress, emotional state. Three participants demonstrated positive trajectories and a further three showed negative trajectories; remaining participants were ambiguous in their response. Injury severity differentiated those with positive trajectories from those with negative trajectories, with greater injury severity apparent for those showing negative trends. Self-concept also improved more in those with positive trajectories. Core demographic variables did not however meaningfully predict the direction of change in core identity or wellbeing indices. Identity-focused songwriting holds promise as a means of promoting healthy identity reintegration. Further research on benefits for those with less severe spinal injuries is warranted.

Therapeutic Potential of Thymoquinone in Glioblastoma Treatment: Targeting Major Gliomagenesis Signaling Pathways

Directory of Open Access Journals (Sweden)

Fabliha Ahmed Chowdhury

2018-01-01

Full Text Available Glioblastoma multiforme (GBM is one of the most devastating brain tumors with median survival of one year and presents unique challenges to therapy because of its aggressive behavior. Current treatment strategy involves surgery, radiotherapy, immunotherapy, and adjuvant chemotherapy even though optimal management requires a multidisciplinary approach and knowledge of potential complications from both the disease and its treatment. Thymoquinone (TQ, the main bioactive component of Nigella sativa L., has exhibited anticancer effects in numerous preclinical studies. Due to its multitargeting nature, TQ interferes in a wide range of tumorigenic processes and counteract carcinogenesis, malignant growth, invasion, migration, and angiogenesis. TQ can specifically sensitize tumor cells towards conventional cancer treatments and minimize therapy-associated toxic effects in normal cells. Its potential to enter brain via nasal pathway due to volatile nature of TQ adds another advantage in overcoming blood-brain barrier. In this review, we summarized the potential role of TQ in different signaling pathways in GBM that have undergone treatment with standard therapeutic modalities or with TQ. Altogether, we suggest further comprehensive evaluation of TQ in preclinical and clinical level to delineate its implied utility as novel therapeutics to combat the challenges for the treatment of GBM.

A reduced-order, single-bubble cavitation model with applications to therapeutic ultrasound.

Science.gov (United States)

Kreider, Wayne; Crum, Lawrence A; Bailey, Michael R; Sapozhnikov, Oleg A

2011-11-01

Cavitation often occurs in therapeutic applications of medical ultrasound such as shock-wave lithotripsy (SWL) and high-intensity focused ultrasound (HIFU). Because cavitation bubbles can affect an intended treatment, it is important to understand the dynamics of bubbles in this context. The relevant context includes very high acoustic pressures and frequencies as well as elevated temperatures. Relative to much of the prior research on cavitation and bubble dynamics, such conditions are unique. To address the relevant physics, a reduced-order model of a single, spherical bubble is proposed that incorporates phase change at the liquid-gas interface as well as heat and mass transport in both phases. Based on the energy lost during the inertial collapse and rebound of a millimeter-sized bubble, experimental observations were used to tune and test model predictions. In addition, benchmarks from the published literature were used to assess various aspects of model performance. Benchmark comparisons demonstrate that the model captures the basic physics of phase change and diffusive transport, while it is quantitatively sensitive to specific model assumptions and implementation details. Given its performance and numerical stability, the model can be used to explore bubble behaviors across a broad parameter space relevant to therapeutic ultrasound.

Do structural changes (eg, collagen/matrix) explain the response to therapeutic exercises in tendinopathy: a systematic review.

Science.gov (United States)

Drew, Benjamin T; Smith, Toby O; Littlewood, Chris; Sturrock, Ben

2014-06-01

Previous reviews have highlighted the benefit of loaded therapeutic exercise in the treatment of tendinopathy. Changes in observable structural outcomes have been suggested as a possible explanation for this response to therapeutic exercise. However, the mechanism for the efficacy of therapeutic exercise remains unclear. To systematically review the relationship between the observable structural change and clinical outcomes following therapeutic exercise. An electronic search of AMED, CiNAHL, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PEDro and SPORTDiscus was undertaken from their inception to June 2012. Any study design that incorporated observable structural outcomes and clinical outcomes when assessing the effect of therapeutic exercise on participants with tendinopathy. Included studies were appraised for risk of bias using the tool developed by the Cochrane Back Review Group. Due to heterogeneity of studies, a qualitative synthesis was undertaken. Twenty articles describing 625 patients were included. Overall, there is a strong evidence to refute any observable structural change as an explanation for the response to therapeutic exercise when treated by eccentric exercise training. Moderate evidence does exist to support the response of heavy-slow resistance training (HSR). The available literature does not support observable structural change as an explanation for the response of therapeutic exercise except for some support from HSR. Future research should focus on indentifying other explanations including neural, biochemical and myogenic changes. Registered with PROSPERO, registration number CRD42011001638.

The relationship between interpersonal problems, therapeutic alliance, and outcomes following group and individual cognitive behaviour therapy.

Science.gov (United States)

McEvoy, Peter M; Burgess, Melissa M; Nathan, Paula

2014-03-01

Cognitive behavioural therapy (CBT) is efficacious, but there remains individual variability in outcomes. Patient's interpersonal problems may affect treatment outcomes, either directly or through a relationship mediated by helping alliance. Interpersonal problems may affect alliance and outcomes differentially in individual and group (CBGT) treatments. The main aim of this study was to investigate the relationship between interpersonal problems, alliance, dropout and outcomes for a clinical sample receiving either individual or group CBT for anxiety or depression in a community clinic. Patients receiving individual CBT (N=84) or CBGT (N=115) completed measures of interpersonal problems, alliance, and disorder specific symptoms at the commencement and completion of CBT. In CBGT higher pre-treatment interpersonal problems were associated with increased risk of dropout and poorer outcomes. This relationship was not mediated by alliance. In individual CBT those who reported higher alliance were more likely to complete treatment, although alliance was not associated with symptom change, and interpersonal problems were not related to attrition or outcome. Allocation to group and individual therapy was non-random, so selection bias may have influenced these results. Some analyses were only powered to detect large effects. Helping alliance ratings were high, so range restriction may have obscured the relationship between helping alliance, attrition and outcomes. Pre-treatment interpersonal problems increase risk of dropout and predict poorer outcomes in CBGT, but not in individual CBT, and this relationship is not mediated by helping alliance. Stronger alliance is associated with treatment completion in individual, but not group CBT. Copyright © 2014 Elsevier B.V. All rights reserved.

Marine microorganisms possess unique metabolic and physiological features and are an important source of new biomolecules, such as biosurfactants. Some of these surface-active compounds synthesized by marine microorganisms exhibit antimicrobial, anti-adhesive and anti-biofilm activity against a broad spectrum of human pathogens (including multi-drug resistant pathogens), and could be used instead of existing drugs to treat infections caused by them. In other cases, these biosurfactants show anti-cancer activity, which could be envisaged as an alternative to conventional therapies. However, marine biosurfactants have not been widely explored, mainly due to the difficulties associated with the isolation and growth of their producing microorganisms. Culture-independent techniques (metagenomics) constitute a promising approach to study the genetic resources of otherwise inaccessible marine microorganisms without the requirement of culturing them, and can contribute to the discovery of novel biosurfactants with significant biological activities. This paper reviews the most relevant biosurfactants produced by marine microorganisms with potential therapeutic applications and discusses future perspectives and opportunities to discover novel molecules from marine environments.

2013-01-01

This study aims to analyze the variables on which depends therapeutic discharge, in patients with a severe dual diagnosis admitted to a professional therapeutic community where their pathology is treated. 325 patients admitted between June 2000 and June 2009 to the therapeutic community. This is a retrospective, cross-sectional study with no control group, based on the detailed analysis of the information collected in a model of semi-structured clinical interview designed in the therapeutic community. The 29.5% of the individuals included in the sample were therapeutically discharged. Of all the variables introduced in this analysis the most significant ones were gender, age at the beginning of treatment, education level, opiate dependence, polidrug abuse, and the presence of psychotic disorders and borderline personality disorder. In our study, gender determines the type of discharge, being therapeutic discharge more frequent among women. A higher educational also increases a better prognosis with a higher rate of therapeutic discharge among individuals with higher education level. A later age at the beginning of the treatment reduces the likelihood of therapeutic discharge. Likewise, polidrug abuse, diagnosis of psychotic disorders and borderline personality disorder are associated to a lower rate of therapeutic discharge. Recognizing these characteristics will allow the early identification of those patients more at risk of dropping treatment hastily, while trying to prevent it by increasing the therapeutic intensity.

Establishing a collaborative relationship is a cornerstone of cognitive behavioural therapy (CBT). Increasingly CBT is being offered to people with intellectual disabilities who may have problems with receptive and expressive communication, and a history of disadvantage or discrimination in their relationships with those in positions of power. Consequently, they may have difficulty establishing a collaborative interaction with their therapist. This paper uses a novel method of interactional analysis to examine if collaboration increases as therapy progresses. Fifteen participants with borderline to mild intellectual disabilities and significant problems of depression, anxiety and anger were recruited from specialist clinical services to participate in this study. Verbatim transcripts of therapy sessions 4 and 9 were coded using an initiative-response method of analysing power distribution in dialogue, to investigate collaboration at the level of therapeutic interaction. The initiative-response scores indicated that power was relatively equally distributed between clients and therapists. On this measure there was no significant increase in collaboration as therapy progressed, as the dialogues were relatively equal from session 4. Analyses of the pattern of interaction showed that whilst the therapists asked most questions, the clients contributed to the flow of the analysis and played an active part in dialogues. The implications of these findings are discussed, along with the possible uses of such interactional analyses in identifying barriers to communication and ways of establishing effective therapeutic dialogue.

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

Science.gov (United States)

Nelson, Brady D.; Hajcak, Greg

2016-01-01

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.

Therapeutic applications of radiopharmaceuticals

International Nuclear Information System (INIS)

Baker, W.J.; Datz, F.L.; Beightol, R.W.

1987-01-01

Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

The student-educator relationship in nursing is very important to the success of teaching and learning. The perceptions of students and educators of this relationship affect its success. Therefore, it is necessary to better understand this relationship. The purpose of the current study was to explore Iranian nursing students' and educators' perceptions of student-educator relationship in clinical nursing education. In this conventional content analysis study, eight Bachelor of Nursing students and 10 clinical nursing educators from nursing and midwifery school in Mashhad (Iran) participated. Purposive sampling was used to select participants. Data were gathered using semistructured interviews. To analyze data, a conventional content analysis approach was used to identify meaning units and their condensation and to make codes and create categories : Results showed that the multidimensional nature of the student-educator relationship in clinical nursing education consists of (a) dimensions related to the educator, (b) dimensions related to the student, and (c) dimensions of relationship quality. Each of these categories is composed of codes that showed the perception of participants about the nature of relationship. On the basis of the unique features and attributes regarding relationship perceptions in clinical nursing education identified among the participants of this study, students and educators in Iran should pay greater attention to establishing the relationship as it relates to these attributes.

Naturally Occurring Anthraquinones: Chemistry and Therapeutic Potential in Autoimmune Diabetes

Directory of Open Access Journals (Sweden)

Shih-Chang Chien

2015-01-01

Full Text Available Anthraquinones are a class of aromatic compounds with a 9,10-dioxoanthracene core. So far, 79 naturally occurring anthraquinones have been identified which include emodin, physcion, cascarin, catenarin, and rhein. A large body of literature has demonstrated that the naturally occurring anthraquinones possess a broad spectrum of bioactivities, such as cathartic, anticancer, anti-inflammatory, antimicrobial, diuretic, vasorelaxing, and phytoestrogen activities, suggesting their possible clinical application in many diseases. Despite the advances that have been made in understanding the chemistry and biology of the anthraquinones in recent years, research into their mechanisms of action and therapeutic potential in autoimmune disorders is still at an early stage. In this paper, we briefly introduce the etiology of autoimmune diabetes, an autoimmune disorder that affects as many as 10 million worldwide, and the role of chemotaxis in autoimmune diabetes. We then outline the chemical structure and biological properties of the naturally occurring anthraquinones and their derivatives with an emphasis on recent findings about their immune regulation. We discuss the structure and activity relationship, mode of action, and therapeutic potential of the anthraquinones in autoimmune diabetes, including a new strategy for the use of the anthraquinones in autoimmune diabetes.

Hereditary haemorrhagic telangiectasia (HHT) is a genetic autosomal-dominant disorder characterized by the presence of epistaxis, vascular telangiectasis in mucosal and cutaneous tissues, with visceral lesions and family history. However, many specialists or radiologists are still in lack of appreciation concerning the full range of consequences in diagnosis and their family relationship resulting the poor recognition of the disease. Understanding the diagnostic imaging and therapeutic measure for HHT will be critical, because of the continuous growth and risk existance of these arteriovenous malformations arousing early diagnosis, proper treatment, adequate follow-up and screening of the family.

Therapeutic potential of eccentric exercises for age-related muscle atrophy

Directory of Open Access Journals (Sweden)

Jae-Young Lim

2016-09-01

Full Text Available Recent studies have focused on evidence-based interventions to prevent mobility decline and enhance physical performance in older adults. Several modalities, in addition to traditional strengthening programs, have been designed to manage age-related functional decline more effectively. In this study, we reviewed the current relevant literatures to assess the therapeutic potential of eccentric exercises for age-related muscle atrophy (sarcopenia. Age-related changes in human skeletal muscle, and their relationship with physical performance, are discussed with reference to in vitro physiologic and human biomechanics studies. An overview of issues relevant to sarcopenia is provided in the context of the recent consensus on the diagnosis and management of the condition. A decline in mobility among the aging population is closely linked with changes in the muscle force–velocity relationship. Interventions based specifically on increasing velocity and eccentric strength can improve function more effectively compared with traditional strengthening programs. Eccentric strengthening programs are introduced as a specific method for improving both muscle force and velocity. To be more effective, exercise interventions for older adults should focus on enhancing the muscle force–velocity relationship. Exercises that can be performed easily, and that utilize eccentric strength (which is relatively spared during the aging process, are needed to improve both muscle force and velocity.

Unique sensitivity of the rabbit eye to X-ray-induced ocular inflammation

Energy Technology Data Exchange (ETDEWEB)

Bito, L Z; Klein, E M [Columbia Univ., New York (USA). Coll. of Physicians and Surgeons

1981-10-01

The effects of X-irradiation of the eye on ocular parameters known to be altered during the inflammatory process were studied on albino and pigmented rabbits, guinea pigs, owl monkeys, cats ducks and pigeons. Within 1.5-3.0 hr after exposure to 10 Gy (1000 rads), all irradiated eyes of either albino or pigmented rabbits showed a significant increase in intraocular pressure, iridial hyperemia, and development of flare and presence of cells in the anterior chamber. Four hours after exposure, the concentration of soluble proteins in the aqueous humor was increased, while that of ascorbic acid was decreased. In contrast, eyes of owl monkeys, cats guinea pigs, ducks and pigeons, exposed to the same or, in some cases, up to eight times higher doses of X-rays, showed no hypertension or development of other parameters of intraocular inflammation. These and previous findings suggest that rabbits, or possibly Lagomorphs in general, are unique among vertebrates in their sensitivity to the early intraocular inflammatory effects of X-rays. In addition, these results seriously question the use of this species as the primary, and frequently sole model for the study of ocular inflammation, its mediation and therapeutics.

Atomoxetine (ATX) is the treatment of choice for attention deficit hyperactivity disorders with co-morbid risk of drug abuse, although its abuse potential needs to be qualified. The purpose of this study is to analyse ATX misuse in relation to therapeutic use and compare our results with that of methylphenidate (MPH). Data on enquiries were extracted from the Danish Poison Information Centre database (January 2006 to June 2012), while data on therapeutic use were provided by the Danish State Serum Institute (2007-2011). The study included 28 ATX and 394 MPH enquiries. Frequency of ATX enquiries did not show a significant correlation to either sale or number of treated patients but for MPH, both correlations were significant (p = 0.001 and p = 0.0008, respectively). The enquiries/number of treated patients relationship differed significantly between ATX and MPH (p = 0.018), but not the enquiries/sale relationship. The proportion of exposures motivated by recreational drug use was significantly lower for ATX (19%) than that for MPH (40%) (p = 0.038). These results suggest that ATX is used by adults for non-medical purposes including recreational use, but to a lesser extent than MPH.

To assess the frequency of osteosclerotic changes on CT that appeared after treatment with gefitinib in patients with lung adenocarcinoma and the relationship between the osteosclerotic changes and the response to the therapy. Our study included 41 patients with lung adenocarcinoma who underwent chest CT both before (CTpre) and after (CTpost) starting treatment with gefitinib. The presence or absence of bone metastases was assessed on the CTpre, and the interval bony change after the therapy was classified as lytic, sclerotic, or no changes on the CTpost. The relationship between treatment results of primary lung cancer and interval bony changes was evaluated. Osteosclerotic lesions were identified in 11 patients (27%) on CTpost; in 6 of 11 patients osteosclerotic lesions newly appeared where the CTpre showed no bone metastasis before the gefitinib therapy. There were significant differences in the therapeutic response of the primary cancers (P < 0.001) and in the survival rate (P < 0.01) in patients with osteosclerotic changes versus those without osteosclerotic changes. Osteosclerotic changes on CT, observed after gefitinib treatment in patients with lung adenocarcinomas, may be an indicator of a good therapeutic response. (orig.)

Embryonic stem cells unlike most adult stem cell populations can replicate indefinitely while preserving genetic, epigenetic, mitochondrial and functional profiles. ESCs are therefore an excellent candidate cell type for providing a bank of cells for allogenic therapy and for introducing targeted genetic modifications for therapeutic intervention. This ability of prolonged self-renewal of stem cells and the unique advantages that this offers for gene therapy, discovery efforts, cell replacement, personalized medicine and other more direct applications requires the resolution of several important manufacturing, gene targeting and regulatory issues. In this review, we assess some of the advance made in developing scalable culture systems, improvement in vector design and gene insertion technology and the changing regulatory landscape.

Kosovo case: A unique arbitrariness

Directory of Open Access Journals (Sweden)

Nakarada Radmila

2007-01-01

Full Text Available The end of Cold war, contrary to expectations has brought new conflicts and forms of violence, new divisions and new relativizations of the international legal order. Taking as an example the endeavors to resolve the Kosovo conflict, the author attempts to indicate the broader implications of the international efforts to constitute an independent state on part of the territory of an existing sovereign state. The arguments used to justify the redefinition of the borders of the Serbian state without its consent, the moral, democratic, peace arguments, are reviewed. Particular attention is paid to the argument that Kosovo is a unique case and therefore unique rules should be applied. The author seeks to understand the deeper significance of these efforts, concluding that dismantling the present international legal order is not only a potential danger but a possible aim.

Estrogen receptor α (ER) ligand-binding domain (LBD) mutations are found in a substantial number of endocrine treatment-resistant metastatic ER-positive (ER + ) breast cancers. We investigated the chromatin recruitment, transcriptional network, and genetic vulnerabilities in breast cancer models harboring the clinically relevant ER mutations. These mutants exhibit both ligand-independent functions that mimic estradiol-bound wild-type ER as well as allele-specific neomorphic properties that promote a pro-metastatic phenotype. Analysis of the genome-wide ER binding sites identified mutant ER unique recruitment mediating the allele-specific transcriptional program. Genetic screens identified genes that are essential for the ligand-independent growth driven by the mutants. These studies provide insights into the mechanism of endocrine therapy resistance engendered by ER mutations and potential therapeutic targets. Copyright © 2018 Elsevier Inc. All rights reserved.

2007-03-01

The notion of therapeutic education was only recently introduced in cancer. Although the term is commonly used, no standard definition exists for the concept and principles of therapeutic education and its efficacy remains to be assessed. Therapeutic education is complementary to the healthcare approach and aims to get the patients more involved in their disease and the treatment decision-making process. This discipline, placed at the interface of human and social sciences, was first developed for the management of chronic diseases (diabetes, asthma). It derives from the principle that involving patients in their own care and management can help them better adjust to life with a chronic disease. The lengthening survival time of cancer patients, which contributes to making cancer a chronic disease, as well as changes in the patient-caregiver relationship contribute to the development of therapeutic education in cancer. Pilot studies, conducted principally in the United States, evaluating the side effects of chemotherapy and the management of pain, have demonstrated that such educational programs could improve patient quality of life and decrease the side effects of treatments. The success of these programs depends on several parameters: taking into account patient's opinion in the elaboration and preparation of the programs; involving skilled multidisciplinary teams engaged in iterative educational actions; having recourse to methodological tools to evaluate the impact of implemented programs. Consistent with the World Health Organization guidelines, research should be conducted in France in order to elaborate and implement cancer-specific education programs and evaluate their potential benefit. Patient education programs on pain, fatigue, nutrition and treatment compliance are currently being developed at Saint-Etienne Regional Resource Centre for cancer information, prevention and education, within the framework of the Canceropole Lyon Auvergne Rhône-Alpes.

Recruiting Terminally Ill Patients into Non-Therapeutic Oncology Studies: views of Health Professionals

Directory of Open Access Journals (Sweden)

Kleiderman Erika

2012-12-01

Full Text Available Abstract Background Non-therapeutic trials in which terminally ill cancer patients are asked to undergo procedures such as biopsies or venipunctures for research purposes, have become increasingly important to learn more about how cancer cells work and to realize the full potential of clinical research. Considering that implementing non-therapeutic studies is not likely to result in direct benefits for the patient, some authors are concerned that involving patients in such research may be exploitive of vulnerable patients and should not occur at all, or should be greatly restricted, while some proponents doubt whether such restrictions are appropriate. Our objective was to explore clinician-researcher attitudes and concerns when recruiting patients who are in advanced stages of cancer into non-therapeutic research. Methods We conducted a qualitative exploratory study by carrying out open-ended interviews with health professionals, including physicians, research nurses, and study coordinators. Interviews were audio-recorded and transcribed. Analysis was carried out using grounded theory. Results The analysis of the interviews unveiled three prominent themes: 1 ethical considerations; 2 patient-centered issues; 3 health professional issues. Respondents identified ethical issues surrounding autonomy, respect for persons, beneficence, non-maleficence, discrimination, and confidentiality; bringing to light that patients contribute to science because of a sense of altruism and that they want reassurance before consenting. Several patient-centered and health professional issues are having an impact on the recruitment of patients for non-therapeutic research. Facilitators were most commonly associated with patient-centered issues enhancing communication, whereas barriers in non-therapeutic research were most often professionally based, including the doctor-patient relationship, time constraints, and a lack of education and training in research

Research examining predictors or correlates of mental health problems among women who experience or use aggression in intimate relationships typically assesses factors that confer risk. Such research has primarily examined intimate partner violence (IPV) victimization or aggression frequency or severity as central risk factors for mental health problems. In the general population, one factor demonstrating a protective effect on mental health problems is self-efficacy. Research on self-efficacy among women who experience or use aggression in intimate relationships is nearly absent. The purpose of this study was to determine if self-efficacy specific to a woman's ability to manage various relationship problems (i.e., relationship self-efficacy [RSE]) played a protective role against the severity of posttraumatic stress, depression, and anxiety symptoms among 354 community-residing women who were victimized and used aggression (bidirectional IPV). Regression analyses found that RSE uniquely predicted each mental health outcome above and beyond what was accounted for by the frequency of physical, sexual, and psychological victimization and aggression. Further, RSE fully mediated the relationships between psychological victimization and each mental health outcome. If replicated, and in circumstances where it is determined safe to do so, findings suggest RSE as a promising avenue for future research to improve the health and well-being of women in bidirectionally aggressive relationships.

Relating Therapist Characteristics to Client Engagement and the Therapeutic Alliance in an Adolescent Custodial Group Substance Misuse Treatment Program.

Client engagement in substance misuse treatment programs is directly associated with positive treatment outcomes. The nature of these programs means there are often difficulties engaging and retaining clients, but authors have consistently found a strong therapeutic alliance is associated with client engagement. While research has focused on the association between the alliance and engagement, the factors that influence the therapeutic alliance have received less attention. To examine therapists' characteristics, namely therapists' stress and empathy levels, as potential predictors of client engagement and the therapeutic alliance, within an adolescent substance misuse group treatment program. The sample included 84 adolescent clients and 14 therapists from a Secure Training Centre in England. Client engagement in the treatment program was observed, while self-reporting measures assessed the therapeutic alliance (client and therapist-rated), and therapists' stress and empathy levels. Multiple regression analysis revealed that therapists' stress levels negatively influenced the therapeutic alliance and had a curvilinear relationship with client engagement, indicating that stress is not exclusively negatively related to engagement. Although stress was found to negatively impact both cognitive and affective empathy, neither cognitive nor affective empathy were significantly related to client engagement or the therapeutic alliance. This study demonstrates the importance of therapist characteristics on client engagement and the therapeutic alliance. Within practice stress can have a positive impact on clients' engagement. Nevertheless, therapists may need additional support to deal with stress effectively. Therapists' empathy may too be fundamental to client engagement, but only it if is perceived by clients.

The present study explored the impact of early symptom change (cognitive and behavioural) and the early therapeutic alliance on treatment outcome in cognitive-behavioural therapy (CBT) for the eating disorders. Participants were 94 adults with diagnosed eating disorders who completed a course of CBT in an out-patient community eating disorders service in the UK. Patients completed a measure of eating disorder psychopathology at the start of treatment, following the 6th session and at the end of treatment. They also completed a measure of therapeutic alliance following the 6th session. Greater early reduction in dietary restraint and eating concerns, and smaller levels of change in shape concern, significantly predicted later reduction in global eating pathology. The early therapeutic alliance was strong across the three domains of tasks, goals and bond. Early symptom reduction was a stronger predictor of later reduction in eating pathology than early therapeutic alliance. The early therapeutic alliance did not mediate the relationship between early symptom reduction and later reduction in global eating pathology. Instead, greater early symptom reduction predicted a strong early therapeutic alliance. Early clinical change was the strongest predictor of treatment outcome and this also facilitated the development of a strong early alliance. Clinicians should be encouraged to deliver all aspects of evidence-based CBT, including behavioural change. The findings suggest that this will have a positive impact on both the early therapeutic alliance and later change in eating pathology. Copyright © 2015 Elsevier Ltd. All rights reserved.

Phase change events of volatile liquid perfluorocarbon contrast agents produce unique acoustic signatures

International Nuclear Information System (INIS)

Sheeran, Paul S; Dayton, Paul A; Matsunaga, Terry O

2014-01-01

Phase-change contrast agents (PCCAs) provide a dynamic platform to approach problems in medical ultrasound (US). Upon US-mediated activation, the liquid core vaporizes and expands to produce a gas bubble ideal for US imaging and therapy. In this study, we demonstrate through high-speed video microscopy and US interrogation that PCCAs composed of highly volatile perfluorocarbons (PFCs) exhibit unique acoustic behavior that can be detected and differentiated from standard microbubble contrast agents. Experimental results show that when activated with short pulses PCCAs will over-expand and undergo unforced radial oscillation while settling to a final bubble diameter. The size-dependent oscillation phenomenon generates a unique acoustic signal that can be passively detected in both time and frequency domain using confocal piston transducers with an ‘activate high’ (8 MHz, 2 cycles), ‘listen low’ (1 MHz) scheme. Results show that the magnitude of the acoustic ‘signature’ increases as PFC boiling point decreases. By using a band-limited spectral processing technique, the droplet signals can be isolated from controls and used to build experimental relationships between concentration and vaporization pressure. The techniques shown here may be useful for physical studies as well as development of droplet-specific imaging techniques. (paper)

2006-01-01

In this study, the effects of personal, situational, and relational variables (such as age, gender, gender role orientation, duration of relationship, relational satisfaction, and physical attractiveness of the partner) on jealousy are investigated. A sample of 454 individuals currently involved in dating or marital relationships (48 % married, 52 % unmarried) completed the Romantic Jealousy Questionnaire, Bem Sex Role Inventory, and Rosenberg Self-Esteem Scale. Stepwise regression analyses and 2 (gender) x2 (gender role orientation) x2 (relational type) ANOVA's were submitted for analyzing the data. Analysis indicated that unmarried people reported higher levels of jealousy than married people (F1-446 = 5.029). Married women reported less jealousy than unmarried women and married women reported more jealousy than married men. Age, relational satisfaction level, expectation level about the duration of the relationship, and physical attractiveness of the partner were unique predictors of the reported level of jealousy (R2 = 0.12; adjusted R2 = 0.11; P physical, emotional, and cognitive responses to jealousy compared to men. Women used more constructive (F1-446 = 6.27) and less destructive strategies than men (F1-446 = 6.27). Unmarried people used more destructive strategies than married people (F1-446 = 3.84). Age, self-esteem, and the duration of the relationship were unique predictors of coping strategies. The present study revealed that jealousy was a multidimensional variable. In particular, relational type, self-esteem, age, relational satisfaction, and sex are highly correlated with jealousy.

[End therapeutic nihilism towards COPD].

Science.gov (United States)

Juergens, Uwe R

2007-03-15

Prevention of COPD requires appropriate patient education, especially of adolescents, as well as the establishment of an effective national health policy. The new GOLD guidelines represent the current standard of knowledge on the management of chronic, progressive, obstructive pulmonary diseases. It points out that COPD is avoidable and treatable,and hence, there is no reason for therapeutic nihilism. Chronic bronchitis preceding a progressive respiratory obstruction cannot be improved with the presently available respiratory therapeutics. For this reason, therapeutic measures concentrate on the avoidance of exacerbations, which are primarily responsible for the severity of the course of COPD.

Antimicrobial Peptides for Therapeutic Applications: A Review

Directory of Open Access Journals (Sweden)

Tsogbadrakh Mishig-Ochir

2012-10-01

Full Text Available Antimicrobial peptides (AMPs have been considered as potential therapeutic sources of future antibiotics because of their broad-spectrum activities and different mechanisms of action compared to conventional antibiotics. Although AMPs possess considerable benefits as new generation antibiotics, their clinical and commercial development still have some limitations, such as potential toxicity, susceptibility to proteases, and high cost of peptide production. In order to overcome those obstacles, extensive efforts have been carried out. For instance, unusual amino acids or peptido-mimetics are introduced to avoid the proteolytic degradation and the design of short peptides retaining antimicrobial activities is proposed as a solution for the cost issue. In this review, we focus on small peptides, especially those with less than twelve amino acids, and provide an overview of the relationships between their three-dimensional structures and antimicrobial activities. The efforts to develop highly active AMPs with shorter sequences are also described.

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

Directory of Open Access Journals (Sweden)

Michael Schnoor

2015-01-01

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.

Psychiatric nurses are aware of the importance of the therapeutic relationship in psychiatric units. Nevertheless, a review of the scientific evidence indicates that theoretical knowledge alone is insufficient to establish an adequate therapeutic alliance. Therefore, strategies are required to promote changes to enhance the establishment of the working relationship. The aims of the study are to generate changes in how nurses establish the therapeutic relationship in acute psychiatric units, based on participative action research and to evaluate the effectiveness of the implementation of evidence through this method. The study will use a mixed method design. Qualitative methodology, through participative action research, will be employed to implement scientific evidence on the therapeutic relationship. A quasi-experimental, one-group, pre-test/post-test design will also be used to quantitatively measure the effectiveness of the implementation of the evidence. Participants will consist of nurses and patients from two psychiatric units in Barcelona. Nurses will be selected by theoretical sampling, and patients assigned to each nurses will be selected by consecutive sampling. Qualitative data will be gathered through discussion groups and field diaries. Quantitative data will be collected through the Working Alliance Inventory and the Interpersonal Reactivity Index. Qualitative data will be analysed through the technique of content analysis and quantitative data through descriptive and inferential statistics. This study will help to understand the process of change in a nursing team working in an inpatient psychiatric ward and will allow nurses to generate knowledge, identify difficulties, and establish strategies to implement change, as well as to assess whether the quality of the care they provide shows a qualitative improvement.

New concepts in therapeutic photomedicine: photochemistry, optical targeting and the therapeutic window

International Nuclear Information System (INIS)

Parrish, J.A.

1981-01-01

Advances in optics technology, synthetic photochemistry, and the science of photobiology make it possible to think beyond phototherapy and photochemotherapy which is dependent on direct photochemical alteration of metabolites or direct phototoxic insult to cells. This report discusses another gender of photomedicine therapy which includes in vivo photoactivation of medicines, photon-dependent drug delivery, and manipulation of host and exposure source to maximize therapeutic index. These therapeutic manipulations are made possible because the skin is highly overperfused and because non-ionizing electromagnetic radiation that enters skin and blood has adequate photon energy to cause electronic excitation. Radiation of 320-800 nm is not very directly phototoxic, is absorbed by a variety of relatively nontoxic photolabile molecules and has an internal dosimetric depth profile. This radiation can therefore be used to activate, deactivate, bind, release or biotransform medications in vivo in skin or other organs. The photochemist, synthetic chemist and photobiologist can collaborate to significantly increase therapeutic possibilities

Interdependencies of Arctic land surface processes: A uniquely sensitive environment

Science.gov (United States)

Bowling, L. C.

2007-12-01

The circumpolar arctic drainage basin is composed of several distinct ecoregions including steppe grassland and cropland, boreal forest and tundra. Land surface hydrology throughout this diverse region shares several unique features such as dramatic seasonal runoff differences controlled by snowmelt and ice break-up; the storage of significant portions of annual precipitation as snow and in lakes and wetlands; and the effects of ephemeral and permanently frozen soils. These arctic land processes are delicately balanced with the climate and are therefore important indicators of change. The litany of recently-detected changes in the Arctic includes changes in snow precipitation, trends and seasonal shifts in river discharge, increases and decreases in the extent of surface water, and warming soil temperatures. Although not unique to the arctic, increasing anthropogenic pressures represent an additional element of change in the form of resource extraction, fire threat and reservoir construction. The interdependence of the physical, biological and social systems mean that changes in primary indicators have large implications for land cover, animal populations and the regional carbon balance, all of which have the potential to feed back and induce further change. In fact, the complex relationships between the hydrological processes that make the Artic unique also render observed historical change difficult to interpret and predict, leading to conflicting explanations. For example, a decrease in snow accumulation may provide less insulation to the underlying soil resulting in greater frost development and increased spring runoff. Similarly, melting permafrost and ground ice may lead to ground subsidence and increased surface saturation and methane production, while more complete thaw may enhance drainage and result in drier soil conditions. The threshold nature of phase change around the freezing point makes the system especially sensitive to change. In addition, spatial

Dental implants modified with drug releasing titania nanotubes: therapeutic potential and developmental challenges.

Science.gov (United States)

Gulati, Karan; Ivanovski, Sašo

2017-08-01

The transmucosal nature of dental implants presents a unique therapeutic challenge, requiring not only rapid establishment and subsequent maintenance of osseointegration, but also the formation of resilient soft tissue integration. Key challenges in achieving long-term success are sub-optimal bone integration in compromised bone conditions and impaired trans-mucosal tissue integration in the presence of a persistent oral microbial biofilm. These challenges can be targeted by employing a drug-releasing implant modification such as TiO 2 nanotubes (TNTs), engineered on titanium surfaces via electrochemical anodization. Areas covered: This review focuses on applications of TNT-based dental implants towards achieving optimal therapeutic efficacy. Firstly, the functions of TNT implants will be explored in terms of their influence on osseointegration, soft tissue integration and immunomodulation. Secondly, the developmental challenges associated with such implants are reviewed including sterilization, stability and toxicity. Expert opinion: The potential of TNTs is yet to be fully explored in the context of the complex oral environment, including appropriate modulation of alveolar bone healing, immune-inflammatory processes, and soft tissue responses. Besides long-term in vivo assessment under masticatory loading conditions, investigating drug-release profiles in vivo and addressing various technical challenges are required to bridge the gap between research and clinical dentistry.

Rughiniş, Cosima; Ciocănel, Alexandra; Vasile, Sorina

2017-09-27

We discuss homeopathy's placebo effect as the result of a distributed therapeutic agency involving humans, objects, and texts. Homeopathy has been involved in controversies for centuries, and the dispute whether it is therapy or quackery is as lively as ever. Still, homeopathy has retained significant popularity and acceptance within the medical establishment. We bracket the issue of biochemical effectiveness of homeopathic remedies as we only discuss homeopathy's potential to elicit a placebo response within its therapeutic alliance, in virtue of its social, symbolic, and material features. The review is based on literature discussing homeopathic effectiveness, including historical, biographical, sociological, and epistemological perspectives. We build upon research that clarifies the therapeutic relationship, examining its activities and meanings for practitioners and patients. Previous analyses discussing homeopathy's placebo effect stress the importance of the individualized consultation that functions as psychotherapy and generates empathy and hope. We enlarge the discussion, highlighting homeopathy's distributed therapeutic agency across humans, texts, and materials. The historical evolution of homeopathy in relation to biomedicine and science is important to understand its institutional integration into mainstream medicine and its appeal to scientifically minded doctors. Anecdotes of healing and the message of no-harm encourage patients to try homeopathy and hope for the best. The esthetics and ritual of remedies, coupled with computers' scientific legitimacy and time-saving power constitute a material infrastructure of therapeutic persuasion. Through its relation with biomedicine, its doctrine, consultation design, and treatment rituals, homeopathy offers a powerful medium to elicit a placebo response in a therapeutic alliance. By virtue of its proximity and radical difference from the scientific and biomedical enterprises, its material and textual

Conceptualising primary labour relationship quality

Lukas I. Ehlers

2017-05-01

Full Text Available Background: A typology of desirable social conditions in supervisory relationships suggested that such conditions may also be desirable in other forms of labour relationships. A literature review confirmed that trust, compliance, fairness and good faith can be confidently regarded as universally desirable social conditions in all forms of individual or collective labour relationships between employers and employees. Aim: The purpose of this study was to determine if primary labour relationship quality (PLQ can be confidently conceptualised as a social construct that strongly relates to the perceived levels of compliance, fairness and good faith in supervisory or primary labour relationships. Setting: A combination of random and convenience sampling approaches was implemented to collect PLQ related data from 454 voluntary respondents, who were subordinate employees in the Tshwane region. Methods: A quantitative research methodology was adopted. This included conceptual definition of the PLQ construct, objective measurement of PLQ levels of voluntary respondents in an adequately sized sample, factor analysis and testing for relationships and differences in means between variables. Results: Data analysis results confirmed that it can be confidently concluded that the conceptual definition of PLQ was valid, and that positive PLQ perceptions of subordinate employees were significantly related to at least two other forms of desirable organisational outcomes. Conclusion: PLQ perceptions can be confidently defined as a distinct subjective quality estimate that is assimilated from unique expectations and perceptions of the levels of compliance, fairness, good faith and trust that a supervisor displays in a labour relationship with an immediate subordinate.

In total, 164 youth (age = 6-17 years, M = 9.97) and their parent(s) presented to an outpatient clinic for a psychoeducational assessment. Between-group analyses and regressions were used to examine study variables. SCT groups were older and exhibited more parent-reported internalizing problems, externalizing problems, sleep problems, and social withdrawal on the Child Behavior Checklist. No significant differences emerged between groups on the Teacher Report Form. Regression analyses involving multiple covariates revealed that SCT symptoms were uniquely related to social withdrawal but not general social problems. Based on parent report, SCT symptoms have a unique relationship with internalizing problems, sleep problems, and social withdrawal. Future research should explore correlates of SCT in youth using multiple informants.

The Ebola virus disease (EVD) crisis in West Africa began in March 2014. At the beginning of the outbreak, no one could have predicted just how far-reaching its effects would be. The EVD epidemic proved to be a unique and unusual humanitarian and public health crisis. It caused worldwide fear that impeded the rapid response required to contain it early. The situation in Sierra Leone (SL) forced the formation of a unique series of civil-military interagency relationships to be formed in order to halt the epidemic. Civil-military cooperation in humanitarian situations is not unique to this crisis; however, the slow response, the unusual nature of the battle itself and the uncertainty of the framework required to fight this deadly virus created a situation that forced civilian and military organisations to form distinct, cooperative relationships. The unique nature of the Ebola virus necessitated a steering away from normal civil-military relationships and standard pillar responses. National and international non-governmental organisations (NGOs), Department for International Development (DFID) and the SL and UK militaries were required to disable this deadly virus (as of 7 November 2015, SL was declared EVD free). This paper draws on personal experiences and preliminary distillation of information gathered in formal interviews. It discusses some of the interesting features of the interagency relationships, particularly between the military, the UK's DFID, international organisations, NGOs and departments of the SL government. The focus is on how these relationships were key to achieving a coordinated solution to EVD in SL both on the ground and within the larger organisational structure. It also discusses how these relationships needed to rapidly evolve and change along with the epidemiological curve. Published by the BMJ Publishing Group Limited.

Sufficient conditions for uniqueness of the weak value

International Nuclear Information System (INIS)

Dressel, J; Jordan, A N

2012-01-01

We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned average using the contextual values formalism introduced in Dressel, Agarwal and Jordan (2010 Phys. Rev. Lett. http://dx.doi.org/10.1103/PhysRevLett.104.240401). We also respond to criticism of our work by Parrott (arXiv:1105.4188v1) concerning a proposed counter-example to the uniqueness of the definition of the generalized weak value. The counter-example does not satisfy our prescription in the case of an underspecified measurement context. We show that when the contextual values formalism is properly applied to this example, a natural interpretation of the measurement emerges and the unique definition in the weak limit holds. We also prove a theorem regarding the uniqueness of the definition under our sufficient conditions for the general case. Finally, a second proposed counter-example by Parrott (arXiv:1105.4188v6) is shown not to satisfy the sufficiency conditions for the provided theorem. (paper)

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

Science.gov (United States)

Nelson, Brady D; Hajcak, Greg

2017-02-01

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.

Uniqueness theorems in linear elasticity

CERN Document Server

Knops, Robin John

1971-01-01

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...

Overcoming the PEG-addiction: well-defined alternatives to PEG, from structure–property relationships to better defined therapeutics

KAUST Repository

Barz, Matthias

2011-01-01

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.

Understanding the role of individual consumer-provider relationships within assertive community treatment.

Science.gov (United States)

Stanhope, Victoria; Matejkowski, Jason

2010-08-01

The widespread adoption of assertive community treatment has resulted in a shift from an individual model to a team model of case management. The shift has had implications for individual relationships between case managers and consumers, but still little is known about how these relationships develop in teams. This exploratory mixed methods study looked at how case managers and consumers negotiate individual relationships within a team model. Quantitative methods identified high and low service intensity relationships between consumers and case managers and qualitative methods explored and compared these relationships. Consumers in high service intensity relationships described a preference for certain case managers and the burden of working with multiple people. Case managers invested high service intensity relationships with special therapeutic value, articulated the challenges of coordinating care across the team, and utilized team limit setting techniques. In contrast, low service intensity relationships were more likely to reflect integration with the entire team. Findings suggest that teams need to consider how individual relationships enhance care for their consumers and how to nurture these relationships while maintaining the support necessary for case managers and consumers.

Associations between the peer support relationship, service satisfaction and recovery-oriented outcomes: a correlational study.

2017-12-18

The working alliance between non-peer providers and mental health consumers is associated with positive outcomes. It is hypothesized that this factor, in addition to other active support elements, is also positively related to peer support service outcomes. This study evaluates correlates of the peer-to-peer relationship and its unique association with service satisfaction and recovery-oriented outcomes. Participants were 46 adults with serious mental illnesses taking part in a peer-brokered self-directed care intervention. Pearson correlation analyses examined associations among peer relationship factors, services-related variables and recovery-oriented outcomes (i.e. empowerment, recovery and quality of life). Hierarchical multiple regression analyses evaluated associations between relationship factors and outcomes over time, controlling for other possible intervention effects. The peer relationship was not related to number of contacts. There were robust associations between the peer relationship and service satisfaction and some recovery-oriented outcomes at 24-months, but not at 12-months. These associations were not explained by other possible intervention effects. This study contributes to a better understanding of the positive, unique association between the peer-to-peer relationship and outcomes, similar to what is found in non-peer-delivered interventions. Implications for program administrators and policymakers seeking to integrate peer specialists into mental health service systems are discussed.

Astroglial networks and implications for therapeutic neuromodulation of epilepsy.

Science.gov (United States)

Witcher, Mark R; Ellis, Thomas L

2012-01-01

Epilepsy is a common chronic neurologic disorder affecting approximately 1% of the world population. More than one-third of all epilepsy patients have incompletely controlled seizures or debilitating medication side effects in spite of optimal medical management. Medically refractory epilepsy is associated with excess injury and mortality, psychosocial dysfunction, and significant cognitive impairment. Effective treatment options for these patients can be limited. The cellular mechanisms underlying seizure activity are incompletely understood, though we here describe multiple lines of evidence supporting the likely contribution of astroglia to epilepsy, with focus on individual astrocytes and their network functions. Of the emerging therapeutic modalities for epilepsy, one of the most intriguing is the field of neuromodulation. Neuromodulatory treatment, which consists of administering electrical pulses to neural tissue to modulate its activity leading to a beneficial effect, may be an option for these patients. Current modalities consist of vagal nerve stimulation, open and closed-loop stimulation, and transcranial magnetic stimulation. Due to their unique properties, we here present astrocytes as likely important targets for the developing field of neuromodulation in the treatment of epilepsy.

Quality Assurance Issues for Therapeutic Application of Radioactive Microspheres

International Nuclear Information System (INIS)

Dezarn, William A.

2008-01-01

The use of radioactive microspheres for the treatment of hepatic cancer is a procedure that raises unique quality assurance (QA) concerns. The greatest of these concerns is the coordination of the responsibilities among the medical team members from interventional radiology, radiation oncology, nuclear medicine, and medical physics. A single QA practice and procedure guidance document does not currently exist that addresses the range of issues of concern for radioactive microspheres. A small sampling of QA issues of concern include imaging QA, procedure-specific imaging protocols, detector calibration, activity measurement, radiation safety, patient dose calculations, and patient-specific QA. Some of the items listed have historically been the responsibility of a single team member, and other items have been concerns for all. A procedural overview of the therapeutic application of radioactive microspheres is presented to illustrate the broad, team-based QA approach necessary to safely and effectively deliver this type of treatment. From this overview, the reader will be able to customize the local QA protocol to meet the local division of responsibilities

VNARs: An Ancient and Unique Repertoire of Molecules That Deliver Small, Soluble, Stable and High Affinity Binders of Proteins

Directory of Open Access Journals (Sweden)

Caroline Barelle

2015-09-01

Full Text Available At 420 million years, the variable domain of New Antigen Receptors or VNARs are undoubtedly the oldest (and smallest antigen binding single domains identified in the vertebrate kingdom. Their role as an integral part of the adaptive immune system of sharks has been well established and has served to provide a greater understanding of the evolution of humoral immunity; their cellular components and processes as well as the underlying genetic organization and molecular control mechanisms. Intriguingly, unlike the variable domain of the camelid heavy chain antibodies or VHH, VNARs do not conform to all of the characteristic properties of classical antibodies with an ancestral origin that clearly distinguishes them from true immunoglobulin antibodies. However, this uniqueness of their origin only adds to their potential as next generation therapeutic biologics with their structural and functional attributes and commercial freedom all enhancing their profile and current success. In fact their small size, remarkable stability, molecular flexibility and solubility, together with their high affinity and selectivity for target, all reinforce the potential of these domains as drug candidates. The purpose of this review is to provide an overview of the existing basic biology of these unique domains, to highlight the drug-like properties of VNARs and describe current progress in their journey towards the clinic.

Cell transplantation with embryonic stem (ES) cell progeny requires immunological compatibility with host tissue. ‘Therapeutic cloning’ is a strategy to overcome this limitation by generating nuclear transfer (nt)ES cells that are genetically matched to an individual. Here we establish the feasibility of treating individual mice via therapeutic cloning. Derivation of 187 ntES cell lines from 24 parkinsonian mice, dopaminergic differentiation, and transplantation into individually matched host mice showed therapeutic efficacy and lack of immunological response.

Bacchini, Dario; Affuso, Gaetana; Aquilar, Serena

2015-10-01

The general purpose of this study was to investigate the relationships between multiple forms and settings of exposure to violence (ETV) as well as personal values and antisocial behavior (ASB) in adolescence. The association of ETV as witness or victim in different contexts (family, school, or neighborhood) and the association of the selected values of power, universalism, and conformity with ASB were analyzed. In addition, the role of ETV in moderating the relationship between values and ASB was tested. A total of 369 adolescents participated in the study. Hierarchical multiple regression analysis was performed. Results revealed that ASB was independently affected by exposure to family violence as a victim, exposure to school violence as a witness, exposure to neighborhood violence as a witness, and by all three selected values. The associations of ASB with universalism and conformity were negative. Conversely, the association of ASB with power was positive. One interaction had statistically significant effects. Results revealed that exposure to school violence as a witness moderates the relationship between universalism and ASB. The results highlight a high percentage of explained variance by ETV and values on ASB and suggest the importance of adopting a socio-ecological framework in interpreting adolescent behavior. © The Author(s) 2014.

The impact of learning communities on interpersonal relationships among medical students.

Science.gov (United States)

Champaloux, Eve Privman; Keeley, Meg G

2016-01-01

Medical students at the University of Virginia (UVA) are mentored and learn within the framework of a four college learning community. Uniquely, these learning communities are used to organize the third-year clerkship rotations. Students were surveyed after their first pre-clinical year and after their clerkship year to determine what the effect of the learning community was on their social and educational interpersonal relationships. Students knew a higher percentage of their college mates after completing their third-year clerkships within the framework of the college system. Students chose peers from within the college system for social and educational interpersonal scenarios statistically more often than what would be expected at random. Small group learning environments that were not formed within the framework of the college system at UVA did not have the same effect on interpersonal relationships, indicating that learning communities are uniquely able to provide a context for relationship building. Students felt more positively about the social and educational effects of the college system after the clerkship year, with a corresponding increase in the strength of their interpersonal bonds with their college peers. This work is the first to investigate the effects of learning communities on interpersonal relationships among medical students and finds that learning communities positively impact both social and educational medical student bonds.

Engineered Bovine Antibodies in the Development of Novel Therapeutics, Immunomodulators and Vaccines

Directory of Open Access Journals (Sweden)

Madhuri Koti

2014-05-01

Full Text Available Some bovine antibodies across all classes are unique, such as the CDR3 of the variable heavy-domain (VH CDR3, which is exceptionally long (up to 66 amino acids, unlike most conventional antibodies where the VH CDR3 loops range from 10 to 25 amino acids. The exceptionally long VH CDR3 is encoded by unusually long germline IGHD genes together with insertion of novel “a” nucleotide rich conserved short nucleotide sequence (CSNS specifically at the IGH V-D junction. Such an exceptionally long VH CDR3 confers unique “knob and stalk” structural architecture where the knob, formed by intra-VH CDR3 disulfide bridges, is separated by 20 Å solvent exposed stalk composed of anti-parallel beta strands. The substitution of the knob with cytokines, such as, erythropoietin and granulocyte colony stimulating factor 3 (granulocyte colony stimulating factor, results in expression of functional fusion proteins with enhanced pharmacokinetics. The beta stranded stalk can be substituted with other rigid structures, for example, repeat alpha helices to form coiled-coil that mimics the beta-stranded stalk and, thus, opens opportunities for insertion of this structure in the CDRs of antibodies across species. Given the versatility of such a structural platform in bovine antibody VH CDR3, it provides the opportunity for the development of new generation of diagnostics, therapeutics, vaccines and immunomodulating drugs.

Therapeutic games to improve attachment capabilities and protect sexual health.

Science.gov (United States)

Beier, Klaus M; Rebensburg, Klaus; Behrmann, Malte

2010-01-01

From the very beginning of life, man's fundamental needs for acceptance, security, trust, warmth and closeness can only be satisfied in relationships [1]. During infancy this is accomplished by body contact and the emotional experience of being taken care of, for instance by the sheltering manner in which an infant is held during breast-feeding. Through this parental loving care the modus of satisfying psychosocial fundamental needs by skin contact is learned by the infant and reinforced on a neuronal level, the way all processes of learning elementary skills generally are. According to present knowledge, chronic lack of security transmitted by frustration of psychosocial fundamental needs increases the probability of developing psychological and physical disorders. Furthermore it hinders overcoming prevailing diseases [2]. In developing therapeutic computer games this phylogenetically established programming for attachment in order to fulfill fundamental psychosocial needs will be the focus of interaction, cognitive triggers and strategic as well as emotional rules to be applied in the games which are designed in a modular way for difficult developmental phases (e.g. adolescence) or various chronic diseases. This is a new approach transferring sexological clinical experience into therapeutic computer games for prevention purposes and protection of sexual health.

On defining a unique phylogenetic tree with homoplastic characters.

Science.gov (United States)

Goloboff, Pablo A; Wilkinson, Mark

2018-05-01

This paper discusses the problem of whether creating a matrix with all the character state combinations that have a fixed number of steps (or extra steps) on a given tree T, produces the same tree T when analyzed with maximum parsimony or maximum likelihood. Exhaustive enumeration of cases up to 20 taxa for binary characters, and up to 12 taxa for 4-state characters, shows that the same tree is recovered (as unique most likely or most parsimonious tree) as long as the number of extra steps is within 1/4 of the number of taxa. This dependence, 1/4 of the number of taxa, is discussed with a general argumentation, in terms of the spread of the character changes on the tree used to select character state distributions. The present finding allows creating matrices which have as much homoplasy as possible for the most parsimonious or likely tree to be predictable, and examination of these matrices with hill-climbing search algorithms provides additional evidence on the (lack of a) necessary relationship between homoplasy and the ability of search methods to find optimal trees.

Unique physiology of host-parasite interactions in microsporidia infections.

Science.gov (United States)

Williams, Bryony A P

2009-11-01

Microsporidia are intracellular parasites of all major animal lineages and have a described diversity of over 1200 species and an actual diversity that is estimated to be much higher. They are important pathogens of mammals, and are now one of the most common infections among immunocompromised humans. Although related to fungi, microsporidia are atypical in genomic biology, cell structure and infection mechanism. Host cell infection involves the rapid expulsion of a polar tube from a dormant spore to pierce the host cell membrane and allow the direct transfer of the spore contents into the host cell cytoplasm. This intimate relationship between parasite and host is unique. It allows the microsporidia to be highly exploitative of the host cell environment and cause such diverse effects as the induction of hypertrophied cells to harbour prolific spore development, host sex ratio distortion and host cell organelle and microtubule reorganization. Genome sequencing has revealed that microsporidia have achieved this high level of parasite sophistication with radically reduced proteomes and with many typical eukaryotic pathways pared-down to what appear to be minimal functional units. These traits make microsporidia intriguing model systems for understanding the extremes of reductive parasite evolution and host cell manipulation.

The unique sensitivity of the rabbit eye to X-ray-induced ocular inflammation

International Nuclear Information System (INIS)

Bito, L.Z.; Klein, E.M.

1981-01-01

The effects of X-irradiation of the eye on ocular parameters known to be altered during the inflammatory process were studied on albino and pigmented rabbits, guinea pigs, owl monkeys, cats ducks and pigeons. Within 1.5-3.0 hr after exposure to 10 Gy (1000 rads), all irradiated eyes of either albino or pigmented rabbits showed a significant increase in intraocular pressure, iridial hyperemia, and development of flare and presence of cells in the anterior chamber. Four hours after exposure, the concentration of soluble proteins in the aqueous humor was increased, while that of ascorbic acid was decreased. In contrast, eyes of owl monkeys, cats guinea pigs, ducks and pigeons, exposed to the same or, in some cases, up to eight times higher doses of X-rays, showed no hypertension or development of other parameters of intraocular inflammation. These and previous findings suggest that rabbits, or possibly Lagomorphs in general, are unique among vertebrates in their sensitivity to the early intraocular inflammatory effects of X-rays. In addition, these results seriously question the use of this species as the primary, and frequently sole model for the study of ocular inflammation, its mediation and therapeutics. (author)

The MB2 gene family of Plasmodium species has a unique combination of S1 and GTP-binding domains

Full Text Available Abstract Background Identification and characterization of novel Plasmodium gene families is necessary for developing new anti-malarial therapeutics. The products of the Plasmodium falciparum gene, MB2, were shown previously to have a stage-specific pattern of subcellular localization and proteolytic processing. Results Genes homologous to MB2 were identified in five additional parasite species, P. knowlesi, P. gallinaceum, P. berghei, P. yoelii, and P. chabaudi. Sequence comparisons among the MB2 gene products reveal amino acid conservation of structural features, including putative S1 and GTP-binding domains, and putative signal peptides and nuclear localization signals. Conclusions The combination of domains is unique to this gene family and indicates that MB2 genes comprise a novel family and therefore may be a good target for drug development.

1988-01-01

The class of uniquely complemented lattices properly contains all Boolean lattices. However, no explicit example of a non-Boolean lattice of this class has been found. In addition, the question of whether this class contains any complete non-Boolean lattices remains unanswered. This book focuses on these classical problems of lattice theory and the various attempts to solve them. Requiring no specialized knowledge, the book is directed at researchers and students interested in general algebra and mathematical logic.

The Importance of The Dentist – Patient Relationship in Oral Cancer Treatment

Directory of Open Access Journals (Sweden)

Indrayadi Gunardi

2017-09-01

Full Text Available Background: There are many instances in oral cancer cases in which a lack of patient cooperation was found to be a hampering factor in the overall case management. A good relationship between dentists and patients should therefore be built in conjunction with other treatment modalities. Case Report: Three complete oral cancer cases with dentist–patient relationship problems are presented. One of the common basic ways to build a good relationship is through communication and empathy. A relationship is also influenced by psychological distress, experience from previous treatments, socioeconomic factors, the healthcare system, time constraints, and belief. Conclusion: No single intervention strategy can improve the compliance of an oral cancer patient. An assessment of patient knowledge and understanding of the regimen along with clear and effective communication and trust in the therapeutic relationship are important in the overall patient management.

Flavonoids at the pharma-nutrition interface: Is a therapeutic index in demand?

Science.gov (United States)

Peluso, Ilaria; Palmery, Maura

2015-04-01

The consumption of flavonoid-rich foods could have beneficial effects on health. However, different classes of flavonoids have different effect on disease risk and the relationship between flavonoid intake and risk of disease appeared to be non-linear. Furthermore, contrarily to vitamins, there are no symptoms of deficiency for flavonoids; therefore, our body treats them like other xenobiotics. Therefore, a therapeutic index should be determined. Despite flavonoids are at the pharma-nutrition interface, drugs and foods are subject to different regulatory frameworks and there is no recommended daily allowance (RDA) for flavonoids. Relatively little is known about the efficacy, safety and underlying mechanisms of these bioactive compounds, especially when taken in concert with drugs. Flavonoids could act both as drugs and pro-drugs with pharmacological and toxicological promiscuity. Due to the low bioavailability, the gastrointestinal tract could be the primary target of flavonoids and metabolites. Different effects have been observed after acute and chronic consumption and bioavailability and bioactivity have high inter-individual variability. Furthermore, the difficulties in the design and in the interpretation of human intervention studies make difficult the establishment of a therapeutic index for flavonoids. Probably the concept of 'personalized nutrition' previously proposed could be the better approach. However, despite more studies are needed in order to establish a therapeutic index for each flavonoid subclasses, at the moment RDA of total flavonoids could be between 250-400 mg/d, respecting the seasonality of food sources.

Effects of therapeutic irradiation delivered in early childhood upon subsequent lung function

International Nuclear Information System (INIS)

Wohl, M.E.B.; Griscom, N.T.; Graggis, D.G.; Jaffe, N.

1975-01-01

To determine the long-term effects of therapeutic pulmonary irradiation and treatment with actinomycin D during a period of lung growth, 12 patients treated for Wilms' tumor metastatic to the lung and 8 patients treated for Wilms' tumor with no evidence of pulmonary metastases were studied 7 to 14 years after their initial tumor therapy. All patients had received irradiation to the tumor bed and treatment with actinomycin D. Group 1 had received a single course of bilateral pulmonary irradiation; group 2 had received additional pulmonary irradiation and/or thoracic surgery; group 3 had received no therapeutic irradiation directed primarily to the chest. Total lung capacity (TLC) averaged 71 percent of predicted value in group 1, 58 percent in group 2, and 94 percent in group 3. Diffusing capacity in groups 1 and 2 was reduced to the same extent as lung volume. Quasi-static pressure-volume relationships, studied in three of six patients in group 1, were within the normal range when lung volume was expressed as percentage of observed TLC. Airway resistance, evaluated by spirometry, maximum expiratory flow-volume curves, and resistance of the total respiratory system, was normal or reduced. The data support the hypothesis that therapeutic irradiation during a period of lung growth primarily affects the lung parenchyma and produces a decrease in subsequent size of both the lung and chest wall. No effect of actinomycin D alone upon the lung could be demonstrated

The companion dog as a unique translational model for aging.

Mazzatenta, Andrea; Carluccio, Augusto; Robbe, Domenico; Giulio, Camillo Di; Cellerino, Alessandro

2017-10-01

The dog is a unique species due to its wide variation among breeds in terms of size, morphology, behaviour and lifespan, coupled with a genetic structure that facilitates the dissection of the genetic architecture that controls these traits. Dogs and humans co-evolved and share recent evolutionary selection processes, such as adaptation to digest starch-rich diets. Many diseases of the dog have a human counterpart, and notably Alzheimer's disease, which is otherwise difficult to model in other organisms. Unlike laboratory animals, companion dogs share the human environment and lifestyle, are exposed to the same pollutants, and are faced with pathogens and infections. Dogs represented a very useful model to understand the relationship between size, insulin-like growth factor-1 genetic variation and lifespan, and have been used to test the effects of dietary restriction and immunotherapy for Alzheimer's disease. Very recently, rapamycin was tested in companion dogs outside the laboratory, and this approach where citizens are involved in research aimed at the benefit of dog welfare might become a game changer in geroscience.

Scanning transmission ion microscopy (STIM) through measurement of energy loss of individual ions is a quantitative imaging technique with several unique capabilities. The uniqueness derives conjointly from the large penetration with small scattering of MeV ions in low-Z specimens, from the simple relationship between energy loss and projected or areal density, and from the almost 100% efficiency with which one obtains pixel data from individual ions. Since contrast is in energy loss and not in numbers of events, the statistics of energy loss straggling affects the image but the statistics of counting does not. Small scattering makes it possible to observe details within transparent specimens. High efficiency makes it possible to collect large data sets for computed tomography, stereo, or high-definition imaging with a small radiation dose. High efficiency allows one to minimize aberrations by use of small apertures, to achieve good precision in the determination of areal density, or even to image live biological specimens in air since only one or a few ions per pixel are required. This paper includes a bibliography on STIM with MeV ions, it discusses the accuracy that one can achieve in the areal density coloring of a pixel with data from one or a few ions, and it supplements that review with recent examples from the Melbourne and the Eugene microprobes.

How protein–protein interaction affects protein–nanoparticle self-assembly is the key to the understanding of biomolecular coating of nanoparticle in biological fluids. However, the relationship between protein shape and its interaction with nanoparticles is still under-exploited because of lack of a well-conceived binding system and a method to detect the subtle change in the protein–nanoparticle assemblies. Noticing this unresolved need, we cloned and expressed a His-tagged SpeA protein that adopts a bridge-shaped dimer structure, and utilized a high-resolution capillary electrophoresis method to monitor assembly formation between the protein and quantum dots (QDs, 5 nm in diameter). We observed that the bridge-shaped structure rendered a low SpeA:QD stoichiometry at saturation. Also, close monitoring of imidazole (Im) displacement of surface-bound protein revealed a unique two-step process. High-concentration Im could displace surface-bound SpeA protein and form a transient QD–protein intermediate, through a kinetically controlled displacement process. An affinity-driven equilibrium step then followed, resulting in re-assembling of the QD–protein complex in about 1 h. Through a temporarily formed intermediate, Im causes a rearrangement of His-tagged proteins on the surface. Thus, our work showcases that the synergistic interplay between QD–His-tag interaction and protein–protein interaction can result in unique properties of protein–nanoparticle assembly for the first time

Full Text Available How the analytical knowledge that compare human consciousness with that, even more disturbing, moving behind his fifth can be said to be “for peace”? It can be - and this will be the contribution of the proposal - the same tortuous and enigmatic of therapeutic practice, with its hesitations and his impulses, to outline a path crossing and overcoming the conflict? May, finally, peace, in the sense of feasibility of intra-and interpersonal dialectic instead of tearing and hostileconfrontation with oneself and with the other, to be a reference in some crucial pivot of ethical therapeutic work? To these questions the intervention seeks to answer retracing some of the highlights of almost three years of therapeutic work with a young woman and her family.

Cancer cachexia is a debilitating metabolic syndrome accounting for fatigue, an impairment of normal activities, loss of muscle mass associated with body weight loss eventually leading to death in majority of patients with advanced disease. Cachexia patients undergoing skeletal muscle atrophy show consistent activation of the SCF ubiquitin ligase (F-BOX) family member Atrogin-1 (also known as MAFBx/FBXO32) alongside the activation of the muscle ring finger protein1 (MuRF1). Other lesser known F-BOX family members are also emerging as key players supporting muscle wasting pathways. Recent work highlights a spectrum of different cancer signaling mechanisms impacting F-BOX family members that feed forward muscle atrophy related genes during cachexia. These novel players provide unique opportunities to block cachexia induced skeletal muscle atrophy by therapeutically targeting the SCF protein ligases. Conversely, strategies that induce the production of proteins may be helpful to counter the effects of these F-BOX proteins. Through this review, we bring forward some novel targets that promote atrogin-1 signaling in cachexia and muscle wasting and highlight newer therapeutic opportunities that can help in the better management of patients with this devastating and fatal disorder.

Therapeutic vaccines aim to control chronic HIV infection and eliminate the need for lifelong antiretroviral therapy (ART). Therapeutic HIV vaccine is being pursued as part of a functional cure for HIV/AIDS. We have outlined a basic protocol for inducing new T cell immunity during chronic HIV-1...... infection directed to subdominant conserved HIV-1 epitopes restricted to frequent HLA supertypes. The rationale for selecting HIV peptides and adjuvants are provided. Peptide subunit vaccines are regarded as safe due to the simplicity, quality, purity, and low toxicity. The caveat is reduced immunogenicity...

Engaging therapeutic citizenship and clientship: Untangling the reasons for therapeutic pacifism among people living with HIV in urban Zambia.

This article explores the reasons for therapeutic pacifism among people living with HIV (PLHIVs) in urban Zambia. It contributes to a growing ethnography on global health, biosociality, and patient-provider dynamics. Therapeutic citizenship is a biopolitical citizenship that includes claims and ethical projects that emerge from techniques to control and manage bodies. In some contexts, therapeutic citizenship has included activism and claims-making against local, national, and international power brokers. This article investigates therapeutic citizenship in the specific context of impoverished urban Zambian compounds, sites of food insecurity, unemployment, and political exclusion, as well as targets for donor, NGO, and faith-based organisation projects and PLHIV support group proliferation. The article utilises data from participant observations at two Lusaka AIDS clinics, interviews, and focused discussions with support groups of PLHIVs. It argues that PLHIVs continuously negotiate subjectivities related to kinship, clientship, religious belief, and political citizenship in processes that complicate therapeutic citizenship. Rather than fostering participation in PLHIV support groups or challenging 'politics as usual' through activist claims-making to institutions of biopower, these processes lead to therapeutic pacifism.

Father involvement research has typically not recognized that reports of involvement contain at least two components: 1 reflecting a view of father involvement that is broadly recognized in the family, and another reflecting each reporter's unique perceptions. Using a longitudinal sample of 302 families, this study provides a first examination of shared and unique views of father involvement (engagement and warmth) from the perspectives of fathers, children, and mothers. This study also identifies influences on these shared and unique perspectives. Father involvement reports were obtained when the child was 12 and 14 years old. Mother reports overlapped more with the shared view than father or child reports. This suggests the mother's view may be more in line with broadly recognized father involvement. Regarding antecedents, for fathers' unique view, a compensatory model partially explains results; that is, negative aspects of family life were positively associated with fathers' unique view. Children's unique view of engagement may partially reflect a sentiment override with father antisocial behaviors being predictive. Mothers' unique view of engagement was predicted by father and mother work hours and her unique view of warmth was predicted by depression and maternal gatekeeping. Taken, together finding suggests a far more nuanced view of father involvement should be considered.

We investigate uniqueness of weak solutions for a system of partial differential equations capturing behavior of magnetoelastic materials. This system couples the Navier–Stokes equations with evolutionary equations for the deformation gradient and for the magnetization obtained from a special case of the micromagnetic energy. It turns out that the conditions on uniqueness coincide with those for the well-known Navier–Stokes equations in bounded domains: weak solutions are unique in two spatial dimensions, and weak solutions satisfying the Prodi–Serrin conditions are unique among all weak solutions in three dimensions. That is, we obtain the so-called weak-strong uniqueness result in three spatial dimensions.
