The City of Collective Melancholy: Revisiting Pamuk’s Istanbul
This essay looks back upon Orhan Pamuk’s non-fiction book, Istanbul: Memories of a City (2003), and unpacks its multi-layered representation of the city as landscape. It is here that Pamuk pursues most overtly “the quest for the melancholic soul of his native city” which won him the 2006 Nobel Prize for Literature. Weaving personal memoir and historical essay into a unique narrative tapestry, Pamuk’s book explores a series of tensions that define the city’s image and identity; insider/outsider and East/West polarities, in particular, are tirelessly deconstructed. The essay examines Pamuk’s poetics and politics of memory in relation to works by other authors, notably Walter Benjamin. In conclusion, the new edition of Istanbul (2015) is discussed against the background of the social and spatial changes that have beset Turkey’s cultural capital in the interim

"Young people, adult worries": RCT of an internet-based self-support method "Feel the ViBe" for children, adolescents and young adults exposed to family violence, a study protocol
Contains fulltext :
116440.pdf (publisher's version ) (Open Access)BACKGROUND: Violence in families affects children. Exposure to violence is seen as child abuse. Figures show that about one third of children exposed to violence become victim or perpetrator in their adult life: known as intergenerational transmission. Violence also affects sexual and reproductive health. To prevent problems in adult life, children need help and support. However, while trying to protect their parents, children often do not seek help, or perceive the threshold as too high. Since almost all children of the current generation have access to the internet, an online intervention will make help better available for this target group. In 2011, an internet-based self-support method for children, adolescents and young adults exposed to family violence was developed in the Netherlands: "Feel the ViBe". The intervention was developed in close collaboration with the target group. This article describes the protocol of the RCT to study the effectiveness of this intervention. METHODS/DESIGN: This study is a randomized controlled trial using the method of minimization to randomize the participants in two parallel groups with a 1:1 allocation ratio, being an intervention group, having access to "Feel the ViBe" and usual care (UC), and a control group, having access to minimally enhanced usual care (mEUC) followed by access to the intervention after twelve weeks. Outcomes are measured with questionnaires on PTSD symptoms, mental health and sexual and reproductive health. Routine Outcome Measurement (ROM) will be used to measure a direct effect of participating in the intervention. Data from a web evaluation questionnaire (WEQ), user statistics and qualitative analysis of online data will be used to support the findings. To compare results Cohen's d effect sizes will be used. DISCUSSION: A RCT and process evaluation will test effectiveness and provide information of how the effects can be explained, how the intervention meets the expectation of participants and which possible barriers and facilitators for implementation exist. A qualitative analysis of the data will add information to interpret the quantitative data. This makes "Feel the ViBe" unique in its field.

Rapid neutrophil mobilization by VCAM-1+ endothelial cell-derived extracellular vesicles
Aims
Acute myocardial infarction rapidly increases blood neutrophils (<2 h). Release from bone marrow, in response to chemokine elevation, has been considered their source, but chemokine levels peak up to 24 h after injury, and after neutrophil elevation. This suggests that additional non-chemokine-dependent processes may be involved. Endothelial cell (EC) activation promotes the rapid (<30 min) release of extracellular vesicles (EVs), which have emerged as an important means of cell–cell signalling and are thus a potential mechanism for communicating with remote tissues.
Methods and results
Here, we show that injury to the myocardium rapidly mobilizes neutrophils from the spleen to peripheral blood and induces their transcriptional activation prior to arrival at the injured tissue. Time course analysis of plasma-EV composition revealed a rapid and selective increase in EVs bearing VCAM-1. These EVs, which were also enriched for miRNA-126, accumulated preferentially in the spleen where they induced local inflammatory gene and chemokine protein expression, and mobilized splenic-neutrophils to peripheral blood. Using CRISPR/Cas9 genome editing, we generated VCAM-1-deficient EC-EVs and showed that its deletion removed the ability of EC-EVs to provoke the mobilization of neutrophils. Furthermore, inhibition of miRNA-126 in vivo reduced myocardial infarction size in a mouse model.
Conclusions
Our findings show a novel EV-dependent mechanism for the rapid mobilization of neutrophils to peripheral blood from a splenic reserve and establish a proof of concept for functional manipulation of EV-communications through genetic alteration of parent cells
