Over the last decade European democracies have been facing a challenge by the rising force of new populist movements. The emergence of the financial and sovereign debt crisis in Europe created new fertile soil for the strengthening of old-established – and the development of new – populist parties in several EU-member states. José Manuel Barroso, president of the European Commission, emphasized his increased unease concerning these developments when he was speaking at the annual Brussels Think Tank Forum on 22. April 2013: “I am deeply concerned about the divisions that we see emerging: political extremes and populism tearing apart the political support and the social fabric that we need to deal with the crisis; […]” (Barroso 2013). Indeed, European elites seem to be increasingly worried by these recent developments which are perceived as an impending stress test of the Union and the project of European integration as a whole (Hartleb 2013). Sure enough, the results of the recent European Parliament Elections 2014 revealed a great support for populist political parties in many societies of EU-member countries. To understand the success of populist parties in Europe it is crucial to first shed light on the nature of populist party communication itself. Significant communicative differences may explain the varying success of populist parties between and within countries, while a pure demand-side approach (i.e. a focus on the preferences of the electorate) often fails to do so (Mudde 2010). The aim of this study is therefore to analyse what different types of populist communication styles emerge during the EP election campaign 2014 and under which conditions populist communication styles are selected by political parties. So far, the empirical measurement of populism has received only scarce attention (Rooduijn & Pauwels 2011). Besides, most of the existing empirical investigations of populism are single case studies (Albertazzi & McDonnell 2008) and scholars have not yet developed systematic methods to measure populism in a comparative way (Rooduijn & Pauwels 2011). This is a consequence of a lack of conceptual clarity which goes along with populism (Taggart 2000; Barr 2009; Canovan 1999) due to its contextual sensitivity. Hence, populism in Europe should be analysed in a way that clarifies the concept of populism and moreover takes into account that the Europeanization of politics has an influence on the type of populist party communication, which is intended in the course of that study.

BACKGROUND There is an urgent need for preclinical models of prostate cancer; however, clinically relevant patient-derived prostate cancer xenografts (PDXs) are demanding to establish. METHODS Sixty-seven patients who were undergoing palliative transurethral surgery or radical prostatectomy for histologically confirmed, clinically relevant prostate cancer were included in the study. Fresh prostate cancer tissue was identified by frozen analysis in 48 patients. The cancer tissue was transplanted subcutaneously and under the renal capsule of NSG and NOG mice supplemented with human testosterone. All growing PDXs were evaluated by histology and immunohistochemistry. RESULTS Early assessment of the animals at least three months after transplantation included 27/48 (56.3%) eligible PDX cohorts. PDX growth was detected in 10/27 (37%) mouse cohorts. Eight of the ten PDXs were identified as human donor derived lymphomas, including seven Epstein Barr virus (EBV)-positive diffuse large B-cell lymphomas and one EBV-negative peripheral T-cell lymphoma. One sample consisted of benign prostatic tissue, and one sample comprised a benign epithelial cyst. Prostate cancer was not detected in any of the samples. CONCLUSIONS Tumors that arise within the first three months after prostate cancer xenografting may represent patient-derived EBV-positive lymphomas in up to 80% of the early growing PDXs when using triple knockout NSG immunocompromised mice. Therefore, lymphoma should be excluded in prostate cancer xenografts that do not resemble typical prostatic adenocarcinoma. Prostate 9999: XX-XX, 2014. © 2015 Wiley Periodicals, Inc.

Acquired thrombotic thrombocytopenic purpura (TTP) is the consequence of a severe ADAMTS13 deficiency resulting from autoantibodies inhibiting ADAMTS13 or accelerating its clearance. Despite the success of plasma exchange the risk of relapse is high. From 2 patients (A and B), splenectomized for recurrent episodes of acquired TTP, the splenic B-cell response against ADAMTS13 was characterized through generation of human monoclonal anti-ADAMTS13 autoantibodies (mAbs) by cloning an immunoglobulin G (IgG)4κ- and IgG4λ-Fab library using phage display technology and by Epstein-Barr virus transformation of switched memory B cells (CD19+/CD27+/IgG+). Sequence analysis of the anti-ADAMTS13 IgGs of both patients revealed that the VH gene use was limited in our patients to VH1-3 (55%), VH1-69 (17%), VH3-30 (7%), and VH4-28 (21%) and contained 8 unique and thus far not reported heavy-chain complementarity determining region 3 motifs, of which 4 were shared by the 2 patients. The discovery of several highly similar anti-ADAMTS13 autoantibodies in 2 unrelated TTP patients suggests that the autoimmune response is antigen driven, because the probability that such similar immunoglobulin rearrangements happen by chance is very low (< 10(-9)).

Non-protein-coding RNAs are a functionally versatile class of transcripts exerting their biological roles on the RNA level. Recently, we demonstrated that the vault complex-associated RNAs (vtRNAs) are significantly upregulated in Epstein-Barr virus (EBV)-infected human B cells. Very little is known about the function(s) of the vtRNAs or the vault complex. Here, we individually express latent EBV-encoded proteins in B cells and identify the latent membrane protein 1 (LMP1) as trigger for vtRNA upregulation. Ectopic expression of vtRNA1-1, but not of the other vtRNA paralogues, results in an improved viral establishment and reduced apoptosis, a function located in the central domain of vtRNA1-1. Knockdown of the major vault protein has no effect on these phenotypes revealing that vtRNA1-1 and not the vault complex contributes to general cell death resistance. This study describes a NF-κB-mediated role of the non-coding vtRNA1-1 in inhibiting both the extrinsic and intrinsic apoptotic pathways.

The UCONN Master of Public Health Program’s Practicum Project The Practicum Project is a supervised service-learning experience that integrates curriculum with hands-on experience in a public health setting. All 2nd year students are expected to work collaboratively in assessing the extent, causes and public health responses to a selected public health problem confronting citizens of Connecticut. The focal topic for the 2007 Project was The Challenges of Living with Disabilities in Connecticut. During this past spring, 17 students of our program, working alongside 50 communitybased stakeholders across Connecticut, completed 1,800 hours of service-learning in pursuit of answers to the following questions: • How is the concept of disability defined by various health and social service providers? • What are the estimated numbers of persons living with disabilities in Connecticut and what is the range of their disabling conditions? • What arrays of services are in place to facilitate the full integration of persons with disabilities into their communities? • What opportunities exist to expand our understanding of the challenges faced by persons living with disabilities and promote public policy on their behalf? This occasion and the accompanying report marks the completion of the 3rd in a series of practicum project reports by UCONN MPH students. Through their combined efforts, students gained experience and skill addressing one of the most significant public health issues of our time; they gained insight into the breadth and capacity of our public health system and established invaluable relationships with public health practitioners, agencies and institutions around the state. Their report documents a rich campus-community partnership to advance public health goals.

The scale-up of antiretrovirals (ARVs) to treat HIV/AIDS in Africa has been rapid over the last five years. Botswana was the first African nation to roll out a comprehensive ARV program, where ARVs are available to all citizens who qualify. Excellent adherence to these ARVs is necessary to maintain HIV suppression and on-going health of all individuals taking them. Children rely almost entirely on their caregivers for the administration of these medications, and very little research has been done to examine the factors which affect both adherence and disclosure to the child of their HIV status. ^ Methods. This cross-sectional study used multiple methods to examine adherence, disclosure, and stigma across various dimensions of the child and caregiver's lives, including 30 caregiver questionnaires, interviewer-administered 3-day adherence recalls, pharmacy pill counts, and chart reviews. Fifty in-depth interviews were conducted with caregivers, male caregivers, teenagers, and health care providers. ^ Results. Perceived family stigma was found to be a predictor of excellent adherence. After controlling for age, children who live with their mothers were significantly less likely to know their HIV status than children living with any other relative (OR=0.403, p=0.014). Children who have a grandmother living in the household or taking care of them each day are significantly more likely to have optimal adherence than children who don't have grandmother involvement in their daily lives. ^ Discussion. Visible illness plays an intermediary role between adherence and perceived family stigma: Caregivers know that ARVs suppress physical manifestations of HIV, and in an effort to avoid unnecessary disclosure of the child's status to family members, therefore have children with excellent adherence. Grandmothers play a vital role in supporting the care and treatment of children in Botswana. ^

El compromiso hepático en la infección por virus Influenza A (H1N1) es muy infrecuente. Presentamos un caso de un paciente varón de 21 años, sano, vacunado, que consulta con un cuadro clásico de gripe. En el examen físico no se palpa hepatoesplenomegalia ni se observa ictericia. Se diagnostica gripe por virus de la influenza A (H1N1) y se inicia tratamiento con oseltamivir oral. Los exámenes de laboratorio revelaron elevación moderada de enzimas hepáticas. Los anticuerpos para virus de la hepatitis A, B y C, virus Epstein-Barr y citomegalovirus (CMV) fueron negativos. El hisopado nasofaríngeo fue positivo para influenza A (H1N1) con prueba de reacción en cadena de polimerasa en tiempo real (PCRRT). Se detectó hepatomegalia homogénea por ecografía abdominal. El cuadro clínico se resolvió en una semana, permaneciendo elevadas las enzimas hepáticas por 21 días. Discutimos los probables mecanismos de la injuria hepática en este caso.

Synthetic seismograms provide a crucial link between lithologic variations within a drill hole and reflectors on seismic profiles crossing the site. In essence, they provide a ground-truth for the interpretation of seismic data. Using a combination of core and logging data, we created synthetic seismograms for Ocean Drilling Program Sites 1165 and 1166, drilled during Leg 188, and Site 742, drilled during Leg 119, all in Prydz Bay, Antarctica. Results from Site 1165 suggest that coring penetrated a target reflector initially thought to represent the onset of drift sedimentation, but the lithologic change across the boundary does not show a change from predrift to drift sediments. The origin of a shallow reflector packet in the seismic line across Site 1166 and a line connecting Sites 1166 and 742 was resolved into its constituent sources, as this reflector occurs in a region of large-scale, narrowly spaced impedance changes. Furthermore, Site 1166 was situated in a fluvio-deltaic system with widely variable geology, and bed thickness changes were estimated between the site and both seismic lines.
