[Intestinal mycobacterial infections in AIDS. Clinical course and treatment of infections caused by Mycobacterium avium, Mycobacterium kansasii, Mycobacterium genavense]
Digestive apparatus is a common target of atypical mycobacteriosis in AIDS patients (at least 50% of patients with CD4+ lymphocytes < 50/mm3). We describe the clinical-histological features of two cases of Whipple-like syndrome likely caused by Mycobacterium avium (MAI) (study performed by light and electron microscopy), of one case of infection caused by two morphological variants of a MAI strain with a different sensitivity to antibiotics, of one case of M. kansasii infection and of two cases of M. genavense infection accompanied by sensitivity tests to antibiotics (as far as we know, these are the first described quantitative sensitivity tests of M. genavense to antibiotics). In conclusion, we discuss the present therapeutical outlines for M. kansasii and avium, together with the teramporary pharmacological options for M. genavense as suggested by antibiotic sensitivity tests performed on the strains isolated from the studied patients

Turbulent kinetic energy redistribution in a gravity current interacting with an emergent cylinder
Gravity currents are flows driven by density gradients between two or more contacting fluids and play a key role in nature and industrial environments via global ocean circulations, climate variability and the distribution of airborne pollutants. In the present work, we study, experimentally, the changes induced by an emergent vertical PVC cylinder on the mean and turbulent flow fields of an unsteady bottom-generated lock release gravity current. Tests were carried out, with and without the cylinder, in refractive index matching conditions and instantaneous velocities were acquired with a Particle Image Velocimetry system. The mean velocity field, Reynolds stresses and terms of turbulent kinetic energy (TKE) budget for the currents head were presented and discussed. The results show that the adverse pressure gradient generated by the cylinder induces a uniform deceleration of the current head. Hence, there are no appreciable differences on the spatial distribution of the mean velocities in the current head, compared to the undisturbed current. On the other hand, the changes on the turbulent flow field are remarkable. The total diffusion of TKE decays in the inner part of the head while becoming stronger at the interface between the two fluids, as the current approaches the cylinder. This is associated to an increase of the diffusion term due to pressure fluctuations, that acts against diffusion due to velocity fluctuations and contributes to disrupt the transport of TKE from the interface between the fluids and the inner part of the current. As a result, in the presence of an obstacle, Reynolds stresses are suppressed in the inner part of the current head and enhanced at the interface
TRASCRITTOMICA COME FRAMEWORK NELLO STUDIO DI NUOVI BIOMARCATORI DI RESISTENZA A STRESS AMBIENTALI: L’ESPERIENZA DI LISTERIA MONOCYTOGENES
Listeria monocytogenes is an ubiquitous bacterium responsible of food contamination causing often severe consequences in immunocompromised or pregnant people. The infection is related to the consumption of ready-to-eat food but also fish, meat, dairy and vegetables. Most important, L. monocytogenes often exhibits persistence and resistant features.
In 2015 a severe outbreak occurred in central Italy causing several infected and death people. The responsible strain was identified in “headcheese” samples which, from the point of view of the bacteria, can be considered a stressor environment in terms of storage temperature, pH,
salt and concentration.
Using a transcriptomic approach, based on a differential expression study, we were able to identify key genes and protein modules responsible
of such a fitness. Although expensive and difficult to apply routinely, RNAseq analysis revealed its usefulness in functional characterization of
pathogens strains

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Towards a Neural Network Model of the Attentional Blink
One of the most prominent experimental paradigms for investigating the deployment of attention over time is the Attentional Blink (AB). Although there is now a great deal known about it, computational modeling of the AB remains only lightly explored. This paper responds to this limitation by proposing a prototype neural network model of the blink. A central aspect of which is a realization of the concept of consolidation into working memory, which is at the heart of the majority of current explanations of the blink
