beta-arrestin-1 competitively inhibits insulin-induced ubiquitination and degradation of insulin receptor substrate 1.

beta-arrestin-1 is an adaptor protein that mediates agonist-dependent internalization and desensitization of G-protein-coupled receptors (GPCRs) and also participates in the process of heterologous desensitization between receptor tyrosine kinases and GPCR signaling. In the present study, we determined whether beta-arrestin-1 is involved in insulin-induced insulin receptor substrate 1 (IRS-1) degradation. Overexpression of wild-type (WT) beta-arrestin-1 attenuated insulin-induced degradation of IRS-1, leading to increased insulin signaling downstream of IRS-1. When endogenous beta-arrestin-1 was knocked down by transfection of beta-arrestin-1 small interfering RNA, insulin-induced IRS-1 degradation was enhanced. Insulin stimulated the association of IRS-1 and Mdm2, an E3 ubiquitin ligase, and this association was inhibited to overexpression of WT beta-arrestin-1, which led by decreased ubiquitin content of IRS-1, suggesting that both beta-arrestin-1 and IRS-1 competitively bind to Mdm2. In summary, we have found the following: (i) beta-arrestin-1 can alter insulin signaling by inhibiting insulin-induced proteasomal degradation of IRS-1; (ii) beta-arrestin-1 decreases the rate of ubiquitination of IRS-1 by competitively binding to endogenous Mdm2, an E3 ligase that can ubiquitinate IRS-1; (iii) dephosphorylation of S412 on beta-arrestin and the amino terminus of beta-arrestin-1 are required for this effect of beta-arrestin on IRS-1 degradation; and (iv) inhibition of beta-arrestin-1 leads to enhanced IRS-1 degradation and accentuated cellular insulin resistance.

EFFECT OF MUSIC ON THE SOUL: INTENT OR INDIFFERENCE IN THE COMPOSITION OF EWAZEN, FETTER, HIDAS, HOVHANESS, PEDERSON AND WILDER

This performance dissertation completed in 2009 by bass trombonist and Doctor of Musical Arts candidate Karl Wiederwohl consists of three live recitals and a written document which serves as a complement to the performances. The document discusses the six composers whose music is performed on the recitals. The document's six chapters respectively discuss each composer's disposition with regard to their purpose in composing music. As a complement to the performances the document gives special attention to each composer's thoughts on affecting listeners through their music. Wiederwohl creates a window into the mentality behind the artistry of Eric Ewazen, David Fetter, Frigyes Hidas, Alan Hovhaness, Tommy Pederson and Alec Wilder. The document serves to inform and enrich the experience of both performers and listeners of these six composers. This is achieved through the document's treatment of the following four questions for each composer: How did each come to be a composer? How did each come to compose in his particular style? Does the composer intend his music to serve a purpose? Does the composer intend his music to serve a purpose, and, if so, does this purpose involve reaching and/or affecting the listener at the deepest level?

Selection with melphalan or paclitaxel (Taxol) yields variants with different patterns of multidrug resistance, integrin expression and in vitro invasiveness

A melphalan-resistant variant (Roswell Park Memorial Institute (RPMI)-2650M1) and a paclitaxel-resistant variant (RPMI-1650Tx) of the drug-sensitive human nasal carcinoma cell line, RPMI-2650. were established. The multidrug resistance (MDR) phenotype in the RPMI-2650Tx appeared to be P-glycoprotein (PgP)-mediated. Overexpression of multidrug resistant protein (MRP) family members was observed in the RPMI-2650M1 cells, which were also much more invasive in vitro than the parental cell line or the paclitaxel-resistant variant. Increased expression of alpha (2), alpha (5), alpha (6), beta (1) and beta (4) integrin subunits, decreased expression of alpha (4) integrin subunit, stronger adhesion to collagen type IV, laminin, fibronectin and matrigel, increased expression of MMP-2 and MMP-9 and significant motility compared with the parental cells were observed, along with a high invasiveness in the RPMI-7650M1 cells. Decreased expression of the alpha (2) integrin subunit, decreased attachment to collagen type IV, absence of cytokeratin 18 expression, no detectable expression of gelatin-degrading proteases and poor motility may be associated with the non-invasiveness of the RPMI-2650Tx variant. These results suggest that melphalan exposure can result in not only a MDR phenotype. but could also make cancer cells more invasive, whereas paclitaxel exposure resulted in MDR without increasing the in vitro invasiveness in the RPMI-2650 cells.

Paul Karl Feyerabend Las proyecciones de la proliferación teórica en la relación ciencia-metafísica

La doctrina de la Proliferación teórica de Paul Karl Feyerabend ha sido interpretada por sus especialistas como un intento de salvaguardar el ideal del progreso científico. Aunque tales estudios hacen justicia, en parte, a la intencionalidad de nuestro filósofo no explicitan la crítica fundamental que implica para Feyerabend el pluralismo teórico. La proliferación teórica constituye en sí misma una reductio ad absurdum de los distintos intentos del positivismo lógico y del racionalismo crítico por definir la ciencia a expensas de lo metafísico. Este artículo presenta la proliferación teórica como una reivindicación del papel positivo que ocupa la metafísica en el quehacer científico. Se consigna la defensa que hace Feyerabend de la metafísica en cuanto que ésta constituye la posibilidad de superar el conservadurismo conceptual, aumentar de contenido empírico de la ciencia y recuperar el valor descriptivo de las teorías científicas.

Degradation and glycemic effects of His(7)-glucitol glucagon-like peptide-1(7-36)amide in obese diabetic ob/ob mice

Glucagon-like peptide-1(7-36)amide (tGLP-1) has attracted considerable potential as a possible therapeutic agent for type 2 diabetes. However, tGLP-1 is rapidly inactivated in vivo by the exopeptidase dipeptidyl peptidase IV (DPP IV), thereby terminating its insulin releasing activity. The present study has examined the ability of a novel analogue, His(7)-glucitol tGLP-1 to resist plasma degradation and enhance the insulin-releasing and antihyperglycemic activity of the peptide in 20-25-week-old obese diabetic ob/ob mice. Degradation of native tGLP-1 by incubation at 37 degreesC with obese mouse plasma was clearly evident after 3 h (35% intact). After 6 h, more than 87% of tGLP-1 was converted to GLP-1(9-36)amide and two further N-terminal fragments, GLP-1(7-28) and GLP-1(9-28). In contrast, His7-glucitol tGLP-1 was completely resistant to N-terminal degradation. The formation of GLP-1(9-36)amide from native tGLP-1 was almost totally abolished by addition of diprotin A, a specific inhibitor of DPP IV. Effects of tGLP-1 and His7-glucitol tGLP-1 were examined in overnight fasted obese mice following i.p. injection of either peptide (30 nmol/kg) together with glucose (18 mmol/kg) or in association with feeding. Plasma glucose was significantly lower and insulin response greater following administration of His7-glucitol tGLP-1 as compared to glucose alone. Native tGLP-1 lacked antidiabetic effects under the conditions employed, and neither peptide influenced the glucose-lowering action of exogenous insulin (50 units/kg). Twice daily s.c. injection of ob/ob mice with His(7)-glucitol tGLP-1 (10 nmol/kg) for 7 days reduced fasting hyperglycemia and greatly augmented the plasma insulin response to the peptides given in association with feeding. These data demonstrate that His(7)-glucitol tGLP-1 displays resistance to plasma DPP IV degradation and exhibits antihyperglycemic activity and substantially enhanced insulin-releasing action in a commonly used animal model of type 2 diabetes.

The metamorphosis of supernova SN 2008D/XRF 080109: A link between supernovae and GRBs/hypernovae

The only supernovae (SNe) to show gamma-ray bursts ( GRBs) or early x-ray emission thus far are overenergetic, broad- lined type Ic SNe ( hypernovae, HNe). Recently, SN 2008D has shown several unusual features: (i) weak x-ray flash (XRF), (ii) an early, narrow optical peak, (iii) disappearance of the broad lines typical of SN Ic HNe, and (iv) development of helium lines as in SNe Ib. Detailed analysis shows that SN 2008D was not a normal supernova: Its explosion energy (E approximate to 6 x 10(51) erg) and ejected mass [similar to 7 times the mass of the Sun ( M.)] are intermediate between normal SNe Ibc and HNe. We conclude that SN 2008D was originally a similar to 30 M. star. When it collapsed, a black hole formed and a weak, mildly relativistic jet was produced, which caused the XRF. SN 2008D is probably among the weakest explosions that produce relativistic jets. Inner engine activity appears to be present whenever massive stars collapse to black holes.

Mood congruent psychotic symptoms and specific cognitive deficits in carriers of the novel schizophrenia risk variant at MIR-137

Objective: The Schizophrenia Psychiatric Genome-wide Association (GWAS) Consortium recently reported on five novel schizophrenia susceptibility loci. The most significant finding mapped to a micro-RNA, MIR-137, which may be involved in regulating the function of other schizophrenia and bipolar disorder susceptibility genes. Method: We genotyped 821 patients with confirmed DSM-IV diagnoses of schizophrenia, bipolar affective disorder I and schizoaffective disorder for the risk SNP (rs1625579) and investigated the clinical profiles of risk allele carriers using a within-case design. We also assessed neurocognitive performance in a subset of cases (n=399) and controls (n=171). Results: Carriers of the risk allele had lower scores for an OPCRIT-derived positive symptom factor (p=0.04) and lower scores on a lifetime measure of psychosis incongruity (p=0.017). Risk allele carriers also had more cognitive deficits involving episodic memory and attentional control. Conclusion: This is the first evidence that the MIR-137 risk variant may be associated with a specific subgroup of psychosis patients. Although the effect of this single SNP was not clinically relevant, investigation of the impact of carrying multiple risk SNPs in the MIR-137 regulatory network on diagnosis and illness profile may be warranted. © 2012 Elsevier Ireland Ltd.

Optical coherence tomography for the diagnosis, monitoring and guiding of treatment for neovascular age-related macular degeneration:a systematic review and economic evaluation

BACKGROUND: Age-related macular degeneration is the most common cause of sight impairment in the UK. In neovascular age-related macular degeneration (nAMD), vision worsens rapidly (over weeks) due to abnormal blood vessels developing that leak fluid and blood at the macula.

OBJECTIVES: To determine the optimal role of optical coherence tomography (OCT) in diagnosing people newly presenting with suspected nAMD and monitoring those previously diagnosed with the disease.

DATA SOURCES: Databases searched: MEDLINE (1946 to March 2013), MEDLINE In-Process & Other Non-Indexed Citations (March 2013), EMBASE (1988 to March 2013), Biosciences Information Service (1995 to March 2013), Science Citation Index (1995 to March 2013), The Cochrane Library (Issue 2 2013), Database of Abstracts of Reviews of Effects (inception to March 2013), Medion (inception to March 2013), Health Technology Assessment database (inception to March 2013).

REVIEW METHODS: Types of studies: direct/indirect studies reporting diagnostic outcomes.

INDEX TEST: time domain optical coherence tomography (TD-OCT) or spectral domain optical coherence tomography (SD-OCT).

COMPARATORS: clinical evaluation, visual acuity, Amsler grid, colour fundus photographs, infrared reflectance, red-free images/blue reflectance, fundus autofluorescence imaging, indocyanine green angiography, preferential hyperacuity perimetry, microperimetry. Reference standard: fundus fluorescein angiography (FFA). Risk of bias was assessed using quality assessment of diagnostic accuracy studies, version 2. Meta-analysis models were fitted using hierarchical summary receiver operating characteristic curves. A Markov model was developed (65-year-old cohort, nAMD prevalence 70%), with nine strategies for diagnosis and/or monitoring, and cost-utility analysis conducted. NHS and Personal Social Services perspective was adopted. Costs (2011/12 prices) and quality-adjusted life-years (QALYs) were discounted (3.5%). Deterministic and probabilistic sensitivity analyses were performed.

RESULTS: In pooled estimates of diagnostic studies (all TD-OCT), sensitivity and specificity [95% confidence interval (CI)] was 88% (46% to 98%) and 78% (64% to 88%) respectively. For monitoring, the pooled sensitivity and specificity (95% CI) was 85% (72% to 93%) and 48% (30% to 67%) respectively. The FFA for diagnosis and nurse-technician-led monitoring strategy had the lowest cost (£39,769; QALYs 10.473) and dominated all others except FFA for diagnosis and ophthalmologist-led monitoring (£44,649; QALYs 10.575; incremental cost-effectiveness ratio £47,768). The least costly strategy had a 46.4% probability of being cost-effective at £30,000 willingness-to-pay threshold.

LIMITATIONS: Very few studies provided sufficient information for inclusion in meta-analyses. Only a few studies reported other tests; for some tests no studies were identified. The modelling was hampered by a lack of data on the diagnostic accuracy of strategies involving several tests.

CONCLUSIONS: Based on a small body of evidence of variable quality, OCT had high sensitivity and moderate specificity for diagnosis, and relatively high sensitivity but low specificity for monitoring. Strategies involving OCT alone for diagnosis and/or monitoring were unlikely to be cost-effective. Further research is required on (i) the performance of SD-OCT compared with FFA, especially for monitoring but also for diagnosis; (ii) the performance of strategies involving combinations/sequences of tests, for diagnosis and monitoring; (iii) the likelihood of active and inactive nAMD becoming inactive or active respectively; and (iv) assessment of treatment-associated utility weights (e.g. decrements), through a preference-based study.

Nurturing attachments in looked after children: a feasibility study of a group-based programme for carers

Introduction: The attachment related difficulties of Looked after Children are well recognised in literature with difficulties linked to early experiences hypothesised to be perpetuated by experiences of the care system itself. Recent policy guidelines have emphasised the importance of relationships for children in care, one of the most important being with their primary carer. Golding (2014) published a group format training resource entitled ‘Nurturing Attachments’ which aims to promote ‘therapeutic parenting’; however there is limited knowledge on the feasibility of this intensive approach.
Aims: To assess the feasibility of Nurturing Attachments through exploring (i.) recruitment, retention and attrition, (ii.) initial outcomes, (iii.) acceptability and (iv.) ability of the programme to be delivered in line with the manual content and structure.
Method Two Health and Social Care Trusts in NI participated in the study by facilitating a Nurturing Attachments group in each site with adoptive parents, foster carers and kinship carers (N = 26). Carers completed pre and post measures to explore initial outcome, completing an evaluation questionnaire to explore acceptability. Acceptability was also explored with Trust stakeholders and group facilitators through focus group and interview. To explore if the manual can be delivered as intended, each group completed debrief tools.
Results: The overall response rate for uptake was 13.9%, which impacted on engagement for a ‘treatment as usual’ group. Once engaged in the programme, attrition was low and attendance was high. Initial outcomes have shown positive effects for both young person and carers. Feedback suggests a positive response regarding acceptability with limited expressed concern. The manual can be delivered in a standardised way; however can be flexible enough to allow for group processes.
Conclusions: Further research is needed to continue to explore efficacy, however the current study has provided supporting evidence that Nurturing Attachments as an intervention has positively impacted on many levels of the LAAC system.

Assessment of biocompatibility of selected ferroelectric ceramics

Desde há muitas décadas que é sabido que os organismos vivos, em especial os tecidos, reagem fisicamente a estímulos eléctricos, podendo esses efeitos reproduzirem-se numa libertação de químicos endógenos, ou deformar a sua estrutura física. O tecido ósseo por si só é considerado um material/tecido piezoeléctrico, deformando-se mecanicamente quando lhe é induzido um estímulo eléctrico e vice-versa, ou seja, produz um potencial eléctrico quando sofre uma tracção ou compressão mecânica. A hipótese de que um material ferroeléctrico possa vir a produzir efeitos no desempenho deste tipo de tecidos é então proposta, como por exemplo, para uma melhor, mais rápida e eficaz regeneração óssea. Estes mesmos materiais ferroeléctricos podem porventura alterar as cargas de superfície dos tecidos vivos de modo a atrair, atrasar ou até impedir o fluxo iónico de elementos químicos específicos responsáveis pelo processo de regeneração. São escolhidos então o niobato de lítio e o tantalato de lítio como cerâmicos ferroeléctricos e foi estudada pela primeira vez a sua bioactividade in vitro, esperando-se encontrar pistas relativas à sua bioactividade in vivo. Estes cerâmicos ferroeléctricos foram seleccionados devido às suas importantes propriedades piezoeléctricas e ferroeléctricas. Estas propriedades podem abrir um novo e importante leque de aplicações biomédicas caso estes cerâmicos sejam bioactivos. Este trabalho foi dividido em 3 fases: (i) sintetização dos pós de niobato de lítio e tantalato de lítio, (ii) caracterização dos pós e (iii) preparação das amostras e (iv) estudo da bioactividade destes cerâmicos ferroeléctricos. Os pós foram produzidos através de um processo simples de mistura/moagem seguido de calcinação. Foram estudadas as fases cristalinas presentes através de Difracção de raios-X (DRX) e avaliadas as características morfológicas destes pós, nomeadamente o diâmetro de partículas e área superficial específica. De modo a simular o ambiente do plasma humano, foi produzido sinteticamente um “Simulated Body Fluid” (SBF). Seguidamente as amostras foram imersas nesse ambiente líquido por 1, 3, 7, 15 e 21 dias. Após remoção dos pós foram realizadas uma série de análises de modo a estudar a sua bioactividade. De entre estes testes destacam-se a microscopia electrónica de varrimento (SEM/EDS), DRX e espectroscopia de Infravermelho por transformada de Fourier com reflectância total atenuada (FTIR-ATR). Embora não tenham sido detectadas alterações no DRX realizado aos pós, verificou-se a formação de aglomerados de fosfato de cálcio na superfície dos pós através do SEM, resultados estes, reforçados pelo EDS e FTIR-ATR. Estes precipitados de fosfato de cálcio indiciam a capacidade destes pós cerâmicos ferroeléctricos se comportarem como bioactivos em contacto com tecidos ósseos in vivo.

The British Army of the Rhine: Turning Nazi Enemies into Cold War Partners

Between 1945 and 1957, West Germany made a dizzying pivot from Nazi bastion to Britain's Cold War ally against the Soviet Union. Successive London governments, though faced with bitter public and military opposition, tasked the British Army of the Rhine (BAOR) to serve as a protecting force while strengthening West German integration into the Western defense structure. Peter Speiser charts the BAOR's fraught transformation from occupier to ally by looking at the charged nexus where British troops and their families interacted with Germany's civilian population. Examining the relationship on many levels, Speiser ranges from how British mass media representations of Germany influenced BAOR troops to initiatives taken by the Army to improve relations. He also weighs German perceptions, surveying clashes between soldiers and civilians and comparing the popularity of the British services with that of the other occupying powers. As Speiser shows, the BAOR's presence did not improve the relationship between British servicemen and the German populace, but it did prevent further deterioration during a crucial and dangerous period of the early Cold War. An incisive look at an under-researched episode, The British Army of the Rhine sheds new light on Anglo-German diplomatic, political, and social relations after 1945, and evaluates their impact on the wider context of European integration in the postwar era.

Versão portuguesa do CANE (Camberwell Assessment of Need for the Elderly) : desenvolvimento e dados preliminares

RESUMO - A avaliação de necessidades de cuidados é crucial no planeamento, monitorização e avaliação de serviços de psiquiatria e saúde mental, bem como na investigação e na clínica. Este princípio é obviamente aplicável aos serviços responsáveis por populações de pessoas mais velhas. O instrumento CANE — Camberwell Assessment of Need for the Elderly possibilita uma avaliação consistente das necessidades de utentes idosos, nomeadamente em situações de patologia neuropsiquiátrica. Procede-se a uma avaliação cruzada, entrevistando a pessoa em questão, o seu cuidador informal e o técnico responsável. Esta avaliação multidimensional abrange domínios da esfera biológica, psicológica e social, sendo aplicável na comunidade ou em internamento (regime parcial ou completo). A utilidade do CANE tem sido evidenciada em contextos clínicos, de investigação e de avaliação de serviços. Existem múltiplas traduções a nível internacional, a maioria das quais validada. Na área da epidemiologia psiquiátrica nem sempre estão disponíveis os dados relativos à qualidade das adaptações de instrumentos, pelo que se apresenta o processo de desenvolvimento da versão portuguesa (de acordo com as regras para validação transcultural, no processo de tradução-retroversão). A aplicabilidade da versão portuguesa foi satisfatória neste estudo-piloto, representando a primeira fase de um trabalho multicêntrico nacional. Nesta fase inicial, foram considerados casos de idosos com patologia neuropsiquiátrica (maioritariamente demência — 71,4%), em dois centros (Lisboa e Porto) (n = 21). A média de idades foi 73,9 (± 6,3) anos, sendo 76,2% do sexo feminino. A maioria vivia em casa, apresentava co-morbilidade somática e estava em contacto com um cuidador informal (em geral, familiares do sexo feminino). Os avaliadores identificaram necessidades, nem sempre cobertas, nas seguintes dimensões: cuidados com a casa, alimentação, actividades diárias, memória, saúde física, sofrimento psicológico, companhia e dinheiro/economias. Nem sempre a perspectiva de doentes, cuidadores, técnicos e avaliadores foi inteiramente coincidente. Estes resultados preliminares da aplicação da versão portuguesa do CANE são consistentes quanto à sua validade ecológica, facial e de conteúdo, estando em curso contributos adicionais para a validação efectiva numa amostra de maior dimensão.
