GrailQuest & HERMES: Hunting for Gravitational Wave Electromagnetic Counterparts and Probing Space-Time Quantum Foam
Within Quantum Gravity theories, different models for space-time quantisation predict an energy dependent speed for photons. Although the predicted discrepancies are minuscule, GRB, occurring at cosmological distances, could be used to detect this signature of space-time granularity with a new concept of modular observatory of huge overall collecting area consisting in a fleet of small satellites in low orbits, with sub-microsecond time resolution and wide energy band (keV-MeV). The enormous number of collected photons will allow to effectively search these energy dependent delays. Moreover, GrailQuest will allow to perform temporal triangulation of high signal-to-noise impulsive events with arc-second positional accuracies: an extraordinary sensitive X-ray/Gamma all-sky monitor crucial for hunting the elusive electromagnetic counterparts of GW. A pathfinder of GrailQuest is already under development through the HERMES project: a fleet of six 3U cube-sats to be launched by 2021/22
Enhanced recovery pathways in thoracic surgery from Italian VATS group: Nursing care program
Enhanced recovery after surgery (ERAS) is an interprofessional program that can lead to hastened patient recovery and reduced time in hospital. Nursing staff play a key role in the implementation of enhanced recovery protocols. This issue focalizes the role of nurses in ERAS program for patients submitted to Thoracic Surgery, in particular for cases of major lung resection performed by a minimally invasive surgical approach (VATS, video assisted thoracic surgery)

What determines social control? People's reactions to counternormative behaviors in urban environments
Social control refers to any reaction by which a bystander communicates to the “perpetrator ” of an uncivil behavior that his or her action is not acceptable. In 3 field studies, we examined the factors that affect people’s tendency to exert social control. Passersby in the streets were asked how they would react were they to witness different uncivil behaviors. They also rated their appraisal of the situation and the emotions they would feel. The results suggest that 3 factors are primary determinants of social control: the feeling of responsibility to exert it; the perceived legitimacy of social control in the situation; and the extent to which bystanders felt hostile emotions. These results have implications for how to reduce uncivil behaviors. Littering, failing to clean up after one’s dog, spitting on the sidewalk, urinating in public, playing loud music in the street, destroying public trashcans, aggressive begging, and parking on the sidewalk are all counternormative behaviors that occur in urban environments. Such behaviors are more and more often subsumed under the term incivilities, to imply that they have something to do with a lack of civility. Unlike delinquent acts, uncivil behavior
Predictors of outcome in an AIEOP series of childhood ependymomas: A multifactorial analysis
Several molecular biomarkers have been suggested as predictors of outcome for pediatric ependymomas but deserve further validation in independent case series. We analyzed intracranial ependymomas belonging to a series of 60 patients prospectively treated according to the protocol sponsored by the Italian Association of Pediatric Hematology-Oncology. We used a tissue microarray to analyze nucleolin (NCL), cyclin-dependent kinase inhibitor 2A (CDKN2A), tumor protein 53 (TP53), and epidermal growth factor receptor (EGFR) by immunohistochemistry and by 1q gain by fluorescent in situ hybridization. The mRNA expression levels of EGFR, human telomerase reverse-transcriptase (HTERT), and Prominin 1 (PROM 1)/CD133 were evaluated by quantitative real-time PCR from cases with fresh-frozen tumor material available. Univariate and multivariate analyses of updated clinical data confirmed the prognostic significance of surgery (P <. 01) and tumor grading (P <. 05) for both relapse-free survival (RFS) and overall survival (OS). Among biomolecular markers, HTERT mRNA expression emerged with the strongest association with OS at multivariate analysis (hazard ratio [HR] 9.9; P <. 011); the 5-year OS was 84 versus 48 in the subgroups with HTERT median value <6 versus <6, respectively (P<. 005). Five-year RFS was 46 versus 20 in the subgroups with low versus high NCL protein expression, respectively (P< . 004), while multivariate Cox analyses gave suggestively high HRs for high versus low NCL (HR 1.9; P< . 090). The other genes tested were not significant at multivariate analyses, and genetic alterations of CDKN2A, TP53, EGFR, and HTERT loci were rare. The PROM1/CD133 cancer stem cell marker was strongly expressed at both RNA and protein levels in a substantial fraction of cases and was suggestively associated with a more indolent form of the disease. We conclude that NCL and HTERT represent the strongest prognostic biomarkers of RFS and OS, respectively, in our ependymoma case series. © 2012 The Author(s)
