Ultrasonographic criteria for the major salivary glands: a perspective for the application of new technologies

It emerges from the interesting recent article by David et al. (4) on high-resolution ultrasound is the first line examination for parotid gland diffuse disease and focal lesions, normally using grey-scale and color-Doppler ultrasound especially using contrast media. Further-more, this working group present a review of the current literature on contrast-enhanced ultrasound for the assessment of parotid gland lesions, considering all characteristics of the technique, evidence of usefulness, future perspectives and limitations. We consider that this type of investigation will be helpful in preoperative treatment planning and reduce the cost to plan the correct treatment of diseases of the parotid glands. I am interested in underlining this article because it shows the advantages of the use of contrast in ultrasound and opens a debate if the non-invasiveness of the ultrasound and the use of the contrast agent have reason to be compared to the use of diagnostics with heavy machines such as CT and MRI. The article is clear on this point the limits are there and it is a challenge to identify new technologies to open unexplored frontiers, to know the disease early and manage it. Making it easier for the patient throughout the diagnosis, therapy, controls and possible follow-up

Is There an Italian Conception of International Law

In 1943, Angelo Piero Sereni wrote The Italian Conception of International Law, a book explicitly aimed at restoring Anglo-American respect for Italian international lawyers after the Fascist period. On the seventieth anniversary of the publication of this work, it is worth considering whether there is, in fact, such a thing as an 'Italian' conception of international law. Methodologically speaking, does thinking of international law in terms of national schools make sense? Although a comparative approach to international law is back in vogue, this article questions the validity of any attempt at finding any 'Italian distinctiveness' in the intellectual history of the Italian school(s) of international law. Sereni's enlisting of ancient masters to an 'Italian' conception between the 13th and 18th centuries is for the most part untenable. While a distinctively Italian conception of international law arguably came into existence in the 19th century with Mancini's theory of nationalities, Anzilotti successfully set out to dissolve this into the 20th century European mainstream of positivist international law. The ensuing absence of an 'Italian' conception may give pause for thought to contemporary proponents of 'comparative international law'

New method in the age estimation by the spheno-occipital suture. 3D cone-beam CT application

The aim of the present study was to determine the sequence and timing of closure of the spheno-occipital synchondrosis for a large sample of a modern Italian population to assess if this age marker is a useful tool for age estimation for individuals. The sample consisted of 494 individuals in the age range 0-22 years, who were admitted to the Department of Radiology, Oncology and Anatomo-Pathology of "Sapienza" University of Rome - UOC Head and Neck Radiology - and the Department of imaging, University of L'Aquila, and who had undergone multi-slice CBCT imaging. The average age of the spheno-occipital closure in men is 18.3 years, whilst in women is 16.6. Therefore, it is evident that the closure in female people is faster than 1.7 years. The timing of closure of spheno-occipital suture can be used to understand the age, even if the research has to be implemented

Apparatus for positioning modular components on a vertical or overhead surface

An apparatus is disclosed for holding a plurality of modular components against a surface. A fixture prepositions the components and a vacuum develops a uniform pressure which presses and holds the fixture and objects against a surface. The surface may be curved, vertical, or overhead and since local load concentrations are avoided, fragile ceramic tiles may be installed using the apparatus

A catalog of known Galactic K-M stars of class I, candidate RSGs, in Gaia DR2

We investigate individual distances and luminosities of a sample of 889 nearby candidate red supergiants with reliable parallaxes (plx/plxerr > 4 and RUWE < 2.7) from Gaia DR2. The sample was extracted from the historical compilation of spectroscopically derived spectral types by Skiff (2014), and consists of K-M stars that are listed with class I at least once. The sample includes well-known red supergiants from Humphreys (1978), Elias et al. (1985), Jura and Kleinmann (1990), and Levesque et al. (2005). Infrared and optical measurements from the 2MASS, CIO, MSX, WISE, MIPSGAL, GLIMPSE, and NOMAD catalogs allow us to estimate the stellar bolometric magnitudes. We analyze the stars in the luminosity versus effective temperature plane and confirm that 43 sources are highly-probably red supergiants with Mbol<-7.1 mag. 43% of the sample is made of stars with masses > 7 Msun. Another 30% of the sample consists of giant stars.Comment: 14 pages, 7 Figures, accepted by ApJ. See https://somethingaboutrsgstars.wordpress.com/ or http://staff.ustc.edu.cn/~messine

Use of acrylic sheet molds for elastomeric products

Molds constructed of acrylic sheet are more easily machined than metal, are transparent to ensure complete filling during injection, and have smooth surfaces free of contamination. Technique eliminates flashing on molded parts and mold release agents

Massive stars in the Cl 1813-178 Cluster. An episode of massive star formation in the W33 complex

Young massive (M >10^4 Msun) stellar clusters are a good laboratory to study the evolution of massive stars. Only a dozen of such clusters are known in the Galaxy. Here we report about a new young massive stellar cluster in the Milky Way. Near-infrared medium-resolution spectroscopy with UIST on the UKIRT telescope and NIRSPEC on the Keck telescope, and X-ray observations with the Chandra and XMM satellites, of the Cl 1813-178 cluster confirm a large number of massive stars. We detected 1 red supergiant, 2 Wolf-Rayet stars, 1 candidate luminous blue variable, 2 OIf, and 19 OB stars. Among the latter, twelve are likely supergiants, four giants, and the faintest three dwarf stars. We detected post-main sequence stars with masses between 25 and 100 Msun. A population with age of 4-4.5 Myr and a mass of ~10000 Msun can reproduce such a mixture of massive evolved stars. This massive stellar cluster is the first detection of a cluster in the W33 complex. Six supernova remnants and several other candidate clusters are found in the direction of the same complex.Comment: 11 Figures. Accepted for publication in Ap
