Filmmaking education and enterprise culture: an ethnographic exploration of two filmmaking education contexts and their relation to bedroom culture and the creative workplace

Filmmaking education has never been firmly integrated into schooling and in past years has suffered from cuts to funding for youth work and formal and non-formal arts education. It continues to exist only by drawing on creative industry and cultural consumption practices as well as state funding. In this paper we explore the filmmaking education contexts we encountered while doing our own pieces of year-long ethnographic research. These contexts import 'enterprising' ways of thinking, doing and being from the creative workplace and 'bedroom culture'. Located across life's domains, they address enterprising subjects who take pleasure in work, make use of leisure, and who are always learning. We argue that these filmmaking education contexts support young people to develop their private creative practice and introduce them to the possibility of work in the creative industries but, because of the enterprise culture in which they are entangled, uncritically address these young people as enterprising subjects

The Role of Physical Stabilization in Whole Blood Preservation

The rapid degradation of blood ex vivo imposes logistical limitations on the utilization of blood-borne cells in medical diagnostics and scientific investigations. A fundamental but overlooked aspect in the storage of this fluid tissue is blood settling, which induces physical stress and compaction, aggregates blood cells, and causes collateral damage due to leukocyte activation. Here we show that the polymer Ficoll 70 kDa stabilized blood samples and prevented blood settling over the course of 72 hours, primarily by inhibiting depletion-mediated red blood cell aggregation. Physical stabilization decreased echinocyte formation, improved leukocyte viability, and inhibited the release of neutrophil elastase—a marker of neutrophil extracellular trap formation. In addition, Ficoll-stabilized blood was compatible with common leukocyte enrichment techniques including red blood cell lysis and immunomagnetic purification. This study showed for the first time that blood settling can be prevented using polymers and has implications in diagnostics

Whole blood stabilization for the microfluidic isolation and molecular characterization of circulating tumor cells

Precise rare-cell technologies require the blood to be processed immediately or be stabilized with fixatives. Such restrictions limit the translation of circulating tumor cell (CTC)-based liquid biopsy assays that provide accurate molecular data in guiding clinical decisions. Here we describe a method to preserve whole blood in its minimally altered state by combining hypothermic preservation with targeted strategies that counter cooling-induced platelet activation. Using this method, whole blood preserved for up to 72 h can be readily processed for microfluidic sorting without compromising CTC yield and viability. The tumor cells retain high-quality intact RNA suitable for single-cell RT-qPCR as well as RNA-Seq, enabling the reliable detection of cancer-specific transcripts including the androgen-receptor splice variant 7 in a cohort of prostate cancer patients with an overall concordance of 92% between fresh and preserved blood. This work will serve as a springboard for the dissemination of diverse blood-based diagnostics

Assessment of stored red blood cells through lab-on-a-chip technologies for precision transfusion medicine

Abstract Transfusion of red blood cells (RBCs) is one of the most valuable and widespread treatments in modern medicine. Lifesaving RBC transfusions are facilitated by the cold storage of RBC units in blood banks worldwide. Currently, RBC storage and subsequent transfusion practices are performed using simplistic workflows. More specifically, most blood banks follow the “first-in-first-out” principle to avoid wastage, whereas most healthcare providers prefer the “last-in-first-out” approach simply favoring chronologically younger RBCs. Neither approach addresses recent advances through -omics showing that stored RBC quality is highly variable depending on donor-, time-, and processing-specific factors. Thus, it is time to rethink our workflows in transfusion medicine taking advantage of novel technologies to perform RBC quality assessment. We imagine a future where lab-on-a-chip technologies utilize novel predictive markers of RBC quality identified by -omics and machine learning to usher in a new era of safer and precise transfusion medicine
