Kill Shakespeare – This Bard contains graphic language!

Today, adapting Shakespearean plays into comic books or graphic novels appears to be a well-established literary practice in contemporary storytelling. One of the most interesting examples is ÒKill ShakespeareÓ, a graphic novel written by Anthony Del Col and Conor McCreery and illustrated by Andy Belanger. In ÒKill ShakespeareÓ, the authors abandon the idea of adapting a single play to create a Shakespearian mashup in which Hamlet and Juliet fight such villains as Richard III and Lady Macbeth who try to kill a wizard named William Shakespeare.This is the premise for a compelling narration that intertwines various elements of the Shakespearean tradition and attempts to convey an idea of Elizabethan language to contemporary readers. While the characters are familiar, the quest is wholly new and triggers a series of transformations in the narrative, turning upside down the well-established images of Hamlet, Juliet and Othello. Beside the intriguing depictions of the female characters, especially Lady Macbeth,whose image poses questions about the representation of women in comic books, one of the most fertile narrative elements in Kill Shakespeare is the actual presence of William Shakespeare as a character. In conclusion, Del Col and McCreery prove they know their Shakespeare, surprising readers with a fresh approach which, hopefully, will enlarge the Shakespearean audience

The transport of nanoparticles in blood vessels: the effect of vessel permeability and blood rheology

The longitudinal transport of nanoparticles in blood vessels has been analyzed with blood described as a Casson fluid. Starting from the celebrated Taylor and Aris theory, an explicit expression has been derived for the effective longitudinal diffusion (Deff) depending non-linearly on the rheological parameter xi(c), the ratio between the plug and the vessel radii; and on the permeability parameters pi and omega, related to the hydraulic conductivity and pressure drop across the vessel wall, respectively. An increase of xi(c) or pi has the effect of reducing Deff, and thus both the rheology of blood and the permeability of the vessels may constitute a physiological barrier to the intravascular delivery of nanoparticles

Topiramato: impiego nel binge eating disorder?

Summary Introduction Topiramate was serendipitously synthesized in 1979 during research aimed at developing a fructose-1,6-diphosphatase inhibitor that might be used in the treatment of diabetes mellitus. Some investigators have suggested it might be used in the treatment of binge eating disorder (BED). The aim of this review was to evaluate current knowledge and opinions on this topic. Materials and methods We conducted a search of five electronic databases (PubMed, Embase, Nice, Cochrane, Cinahl) using the search strategy "topiramate" AND "binge", "binge eating disorder." No time limits were applied, and only reports of randomized controlled trials were included in our analysis. Results In clinical studies, topiramate use has been associated with significant weight loss mediated by reductions in the frequency of bingeing episodes. The most common side effects of the drug are paresthesias, but nephrolithiasis, oligohydrosis, and dizziness have also been described. Conclusions Available data are limited, but the literature we reviewed suggests that topiramate can be useful in the medical treatment of BED, reducing both body weight and binge episodes. Side effects are not negligible. Before topiramate can be regarded as a good tool for the treatment of BED, further data must be obtained from longer, methodologically correct studies of larger populations

The margination propensity of spherical particles for vascular targeting in the microcirculation

The propensity of circulating particles to drift laterally towards the vessel walls (margination) in the microcirculation has been experimentally studied using a parallel plate flow chamber. Fluorescent polystyrene particles, with a relative density to water of just 50 g/cm3comparable with that of liposomal or polymeric nanoparticles used in drug delivery and bio-imaging, have been used with a diameter spanning over three order of magnitudes from 50 nm up to 10 mum.

However, the margination in vertical capillaries is predicted to be much smaller than in horizontal capillaries. These results suggest that, for particles circulating in an external field of volume forces (gravitation or magnetic), the strategy of using larger particles designed to marginate and adhere firmly to the vascular walls under flow could be more effective than that of using particles sufficiently small (d < 200 nm) to hopefully cross a discontinuous endothelium

Soot inception: A DFT study of σ and π dimerization of resonantly stabilized aromatic radicals

Recent advances in the soot studies have shown experimental evidences of π-radicals and cross-linked structures among the molecular constituents of just-nucleated soot particles. π-radicals could have an important role in particle nucleation by increasing the binding energy between polycyclic aromatic hydrocarbons with respect to pure van der Waals interactions. In this work we use density functional theory by Grimme D3 dispersion correction (DFT-D3) with hybrid functional and localized Gaussian basis set (B3LYP/6-31G**) to analyze and classify the clustering behaviors of two aromatic radicals visualized experimentally by atomic force microscopy (Commodo et al. Combust. Flame 205: 154–164, 2019). These aromatic radicals have different topological structures and delocalization of the unpaired electron. The binding energy and energy bandgap characteristics of the clusters are calculated. The theoretical results show a different clustering behavior for the two aromatic radicals. The one with a partial localization of the unpaired electron tends to form a σ-dimer; conversely, the radical with a greater delocalization of the unpaired electron leads to π-stacking formation with a slight overbinding of few kcal mol−1 with respect to pure van der Waals interactions and a marked lowering of the energy bandgap. The formation of π-stacking induced by delocalized π-radicals could in part explain some spectroscopic evidences observed during soot nucleation. © 2020 Elsevier Lt

Surveying, modeling and communication techniques for the documentation of medieval wooden painted ceilings in the Mediterranean area

Wooden painted ceilings of the Mediterranean area in the middle age have their origin in the islamic culture and were then spread in the countries under the dominion of the Arabs; some of the surviving ceilings are now located in Sicily and Spain. In the historic centre of Palermo two well preserved medieval ceilings are still surviving; the first, built in the XII century, is located in the Palatine chapel; the second one, built in the XIV century covers the “Sala Magna” in the Steri of Palermo. The research, focused on the ceiling in the Steri, deals with the definition of a process for the integration of surveying techniques (photogrammetry, laser scanning), modelling processes and communication technologies for the documentation of such artefacts. The documentation of painted ceilings requires the strict integration of photographic and 3D metric data; the existing documentation is usually made of documents (drawings, photographs) that keep geometric and metric data separated from the photographic documentation of the paintings. The first stage in this work is therefore addressed to produce a digital document that combines metric and photographic data in a 3D textured model; in the second stage a vocal guide interacting with the 3D model has been developed; such guide, thought as a support to people visiting the Steri, uses a database with historic contents and symbolic interpretation of the painted scenes to answer specific questions and “take” the visitor close to the related paintings

Diagnostic accuracy of sonohysterography vs hysteroscopy in benign uterine endocavitary findings

OBJECTIVE: To compare diagnostic accuracy of sonohysterography vs hysteroscopy in patients with benign uterine endocavitary findings. PATIENTS AND METHODS: This retrospective study evaluated 202 patients submitted to sonohysterography after transvaginal ultrasound examination suspicious for uterine endocavitary findings. Cytological sample was taken and analyzed from the fluid used to distend the uterine cavity. Of 202 patients enrolled for this study, 86 patients underwent gynaecological surgery, of whom 77 were treated with operative hysteroscopy and 9 with other gynaecological surgical techniques. Statistical analysis was performed to evaluate diagnostic agreement between sonohysterography vs hysteroscopy and cytology vs histology. RESULTS: Diagnostic concordance between sonohysterography and hysteroscopy was significant (k value 0.87). The correlation between cytological and histological findings had a moderate level of concordance (k value 0.49).CONCLUSIONS: Sonohysterography provides a diagnostic accuracy as well as hysteroscopy, therefore, it could be considered an alternative procedure in the diagnosis of benign uterine endocavitary findings

Estimating abundance and habitat suitability in a micro-endemic snake: the Walser viper

Recently described species suffer lack of information that hampers setting up appropriate conservation strategies. The situation is particularly complex with micro-endemic snakes, for which detection and monitoring are particularly challenging. The Walser viper Vipera walser is a recently described snake inhabiting a small area of the SW Italian alps. We combined information on species distribution with repeated monitoring to identify the areas most suitable for the species, and to obtain estimates of species abundance. Species distribution models were used to identify the topographical, climatic, and land-cover features related to the occurrence of vipers. Furthermore, repeated transects and N-mixture models were used to estimate abundance and to identify factors related to the variation of abundance. The available data suggested that the species has a disjunct range, with a Northern range of ~45 km2 , and a southern range of ~225 km2. Distribution models suggested that vipers are associated with areas with open egetation,altitude between 1300 and 2300 m, high precipitation, low forest cover, low slope, and southern aspect. N-mixture models confirmed very low detection probability of these vipers, and suggested that the species has a low abundance,with the highest abundance in south-facing plots. We provide the first quantitative information on habitats and abundance variation for Walser vipers. The broad confidence intervals of abundance estimates exemplify the complexity of providing range-wide measures of abundance for secretive species. Given the narrow range of these vipers, continuous monitoring is required to understand how they respond to ongoing environmental changes in mountainous areas
