Differential inhibition of the Fas- and granule-mediated cytolysis pathways by the orthopoxvirus cytokine response modifier A/SPI-2 and SPI-1 protein.

Cytotoxic T lymphocytes are important effectors of antiviral immunity, and they induce target cell death either by secretion of cytoplasmic granules containing perforin and granzymes or by signaling through the Fas cell surface antigen. Although it is not known whether the granule-mediated and Fas-mediated cytolytic mechanisms share common components, proteinase activity has been implicated as an important feature of both pathways. The orthopoxviruses cowpox virus and rabbitpox virus each encode three members of the serpin family of proteinase inhibitors, designated SPI-1, SPI-2, and SPI-3. Of these, SPI-2 (also referred to as cytokine response modifier A in cowpox virus) has been shown to inhibit the proteolytic activity of both members of the interleukin 1 beta converting enzyme family and granzyme B. We report here that cells infected with cowpox or rabbitpox viruses exhibit resistance to cytolysis by either cytolytic mechanism. Whereas mutation of the cytokine response modifier A/SPI-2 gene was necessary to relieve inhibition of Fasmediated cytolysis, in some cell types mutation of SPI-1, in addition to cytokine response modifier A/SPI-2, was necessary to completely abrogate inhibition. In contrast, viral inhibition of granule-mediated killing was unaffected by mutation of cytokine response modifier A/SPI-2 alone, and it was relieved only when both the cytokine response modifier A/SPI-2 and SPI-1 genes were inactivated. These results suggest that an interleukin 1 beta converting enzyme-like enzymatic activity is involved in both killing mechanisms and indicate that two viral proteins, SPI-1 and cytokine response modifier A/SPI-2, are necessary to inhibit both cytolysis pathways.

Genomic structure of human microtubule-associated protein 2 (MAP-2) and characterization of additional MAP-2 isoforms.

We have determined that the gene for human microtubule-associated protein 2 (MAP-2) spans 19 exons, including 6 exons identified in this study, 1-4, 8, and 13; all six of these exons are transcribed. The alternative splicing of coding exons generates a greater diversity of MAP-2 transcripts and isoforms. The first three exons encode alternate 5' untranslated regions that can be spliced to additional untranslated sequences contained in exons 4 and 5. Exons 8 and 13 are transcribed in human fetal spinal cord, adult brain, MSN cells, and rat brain, and each exon maintains an open reading frame with both high and low molecular weight MAP-2 isoforms. Antibodies generated to synthetic peptides of exons 8 and 13 demonstrate that these exons are translated and MAP-2 isoforms containing these exons are generated.

Avaliação da função ventricular direita por meio da ecocardiografia em cães com doença valvar crônica de mitral

A doença valvar crônica de mitral (DVCM) é a principal cardiopatia adquirida dos cães e uma das suas complicações é a hipertensão arterial pulmonar (HAP), o que pode induzir a disfunção do ventriculo direito (VD). Assim, constituíram-se em objetivos do presente estudo identificar e descrever alterações de tamanho do VD, padrão de fluxo na artéria pulmonar (AP) e função sistólica ventricular direita nas diferentes fases da DVCM, além de correlacionar estas variáveis com índices de tamanho, volume, funções sistólica e diastólica do lado esquerdo do coração, bem como com a velocidade da insuficiência tricúspide (IT) e gradiente de pressão entre o ventrículo e átrio direitos nos cães que apresentavam regurgitação da valva tricúspide. Para tanto, foram incluídos 96 cães de diversas raças no estudo, que foram separados em quatro grupos de acordo com o estágio da DVCM: grupos ou estágios A, B1, B2 e C. Os cães com DVCM sintomáticos ou em estágio C apresentaram alterações no fluxo da artéria pulmonar (AP), bem evidenciadas pela redução das suas velocidades máxima e média, além da redução dos tempos de aceleração (TAC) e ejeção (TEJ) do fluxo sistólico da AP e correlação negativa com as variáveis de tamanho e funções sistólica e diastólica do coração esquerdo. O tamanho do VD foi estatisticamente maior nos animais do estágio C em comparação aos do estágio B1 e associou-se, negativamente, com os índices de função sistólica ventricular esquerda (VE). Os índices de função sistólica do VD como índice de excursão sistólica do plano anular tricúspide (iTAPSE) e variação fracional de área (FAC) foram maiores nos estágios mais avançados da DVCM e, juntamente com a velocidade de movimentação miocárdica sistólica do anel valvar tricúspide (onda Sm), correlacionou-se com índices de funções sistólica e diastólica do VE, seguindo o mesmo padrão de aumento de movimentação e estado hipercinético das variáveis do lado esquerdo do coração na evolução da DVCM. O padrão de fluxo sistólico da AP, bem caracterizado pelo TAC e TEJ, e o índice de área doVD foram os índices que mais alteraram com a evolução da hipertensão pulmonar na DVCM, enquanto que os índices de função do VD não apresentaram alterações significativas neste modelo de hipertensão arterial pulmonar em cão

Self-Injurious Behavior And Its Relationship To Eating Disorder Symptom Severity

Widely held clinical assumptions about self-harming eating disorder patients were tested in this project. Specifically, the present study had two aims: (1) to confirm research that suggests patients with self-injurious behavior exhibit greater severity in eating disorder symptomology; and (2) to document the treatment course for these patients (e.g. reported change in eating disorder attitudes, beliefs, and behaviors) from admission to discharge. Data from 43 participants who received treatment at a Partial Hospitalization Program (PHP) for Eating Disorders were used in the current study. The length of treatment required for study inclusion reflected mean lengths of stay (Williamson, Thaw, & Varnardo-Sullivan, 2001) and meaningful treatment lengths in prior research (McFarlane et al., 2013; McFarlane, Olmsted, & Trottier, 2008): five to eight weeks. Scores on the Eating Disorder Inventory-III (Garner, 2004) at the time of admission and discharge were compared. These results suggest that there are no significant differences between eating disordered patients who engage in self-injury and those who do not in terms of symptom severity or pathology at admission. The results further suggest that patients in both groups see equivalent reductions in symptoms from admission to discharge across domains and also share non-significant changes in emotional dysregulation over the course of treatment. Importantly, these results also suggest that general psychological maladjustment is higher at discharge for eating disordered patients who engage in self-injury.

Why EU promotion is at odds with successful crisis management: public relations, news coverage, and the Aceh Monitoring Mission. EU Centre in Singapore Working Paper No. 10, September 2012

The EU’s Common Foreign and Security Policy (CFSP) and its accompanying Common Security and Defence Policy (CSDP) missions can be tools used to increase the international profile of the European Union. Nevertheless, CSDP missions garner little news coverage. This article argues that the very nature of the missions themselves makes them poor vehicles for EU promotion for political, institutional, and logistical reasons. By definition, they are conducted in the middle of crises, making news coverage politically sensitive. The very act of reporting could undermine the mission. Institutionally, all CSDP missions are intergovernmental, making press statements slow, overly bureaucratic, and of little interest to journalists. Logistically, the missions are often located in remote, undeveloped parts of the world, making it difficult and expensive for European and international journalists to cover. Moreover, these regions in crisis seldom have a thriving, local free press. Using the Aceh Monitoring Mission (AMM) as a case study, the author concludes that although a mission may do good, CSDP missions cannot fulfil the political function of raising the profile of the EU.

The Kremlin plays the immigration card. OSW Commentary No. 112, 2013-08-19

Russia is currently the world’s second most popular destination country for international migrants (second only to the United States). In recent years, Russia’s relatively high economic growth has attracted foreign workers from poorer neighbouring republics in Central Asia, as well as from Ukraine and Belarus. In the absence of a consistent immigration policy, the largescale influx of immigrants has become a major issue affecting social relations in Russia. The majority of Russians oppose the arrival of both foreign workers and internal migrants from Russia’s North Caucasus republics, claiming that their presence in Russia contributes to the escalation of ethnic and religious tensions, fuels organised crime and corruption, and increases competition on the labour market. As many as 70% of Russians are in favour of restricting the number of immigrants allowed into the country, calling on the government for a more stringent policy on immigration. Since the end of July the authorities have responded to these calls by carrying out a series of raids on markets and construction sites across Moscow, where most immigrants tend to find employment. The raids have led to arrests and deportations. However, these measures should not be seen as a serious attempt to deal with the problem of economic migrants in the capital, mainly because of the highly selective and staged nature of the crackdown. This, coupled with the timing of the initiative, might indicate that the raids are a part of an ongoing election campaign, particularly in the run-up to the Moscow mayoral elections scheduled for 8 September. By adopting anti-immigration rhetoric, the Kremlin is seeking both to garner support among Russian voters, who tend to be easily swayed by nationalist sentiments, and to steal the anti-immigration card from the opposition and its leader Alexei Navalny. The opposition has been calling for a clearer policy on this issue and has blamed the government for the current lack of control over migrant numbers, accusing the authorities of benefiting from the widespread corruption linked to immigration. In a broader context, the actions taken by the government are a response to the declining legitimacy of the current ruling elite. By attempting to address the immigration issue, the Kremlin is trying to restore its image as a government attentive to social problems and capable of solving them effectively.
