The demonstration of the Sense Organs in the waxes of the Bologna school between XVIII and XIX century
In the field of the morphological disciplines the name of Filippo Pacini (1812-1883) is mostly related to the discovery of the sensitive Pacinian Corpuscles of the skin, but also to studies about the eye, particularly in the microscopical structure of the retina. Because this important respect of his scientific work, it seems appropriate to investigate the contribution of anatomical wax modelling to the representation of the sense organs between XVIII end XIX century. Considering the school of Ercole Lelli (1702-1766) in Bologna, of particular interest are the models made by Anna Morandi Manzolini (1716-1775). The approach in demonstrating the sense of tact is exquisitely functional, not only anatomical, by a wax reproducing two hands, one of them in the action of touching, the other withdrawing from a wounding object, thus giving a lively scene of a function, the tact, that at time science could not yet explain in their inner mechanisms. In the set of waxes about the vision, besides the general conformation of the eye and of the extrinsic muscles, is well presented the structure of the eyeball with the three tunics and vessels. Quite different in the artistic feature are the models of the eye and lachrymal apparatus performed by Cesare Bettini (1814-1885) about a century later. These waxes are of great dimensions, to be more useful for their educational purposes. The waxes of the school of Bologna not show the microscopic appearance of the organs: it was still too early for this kind of knowledge at the time of Anna Morandi Manzolini, but also the preparations of the wax modelers of the XIX century, at the epoch of the anatomists Francesco Mondini (1786-1844) and Luigi Calori (1807-1896), are not devoted to these fine aspects, that instead we can find in other collections, as those of the Anatomy Museum of the University of Florence
Characterization of the AP-1 μ1A and μ1B adaptins in zebrafish (Danio rerio)
Protein transport between the trans-Golgi network and endosomes is mediated by transport vesicles formed by the adaptor-protein complex AP-1, consisting of the adaptins γ1, β1, μ1, σ1. Mammalia express μ1A ubiquitously and isoform μ1B in polarized epithelia. Mouse γ1 or μ1A 'knock out's revealed that AP-1 is indispensable for embryonic development. We isolated μ1A and μ1B from Danio rerio. Analysis of μ1A and μ1B expression revealed tissue-specific expression for either one during embryogenesis and in adult tissues in contrast to their expression in mammalia. μ1B transcript was detected in organs of endodermal derivation and "knock-down" experiments gave rise to embryos defective in formation of intestine, liver, and pronephric ducts. Development ceased at 7-8 dpf. μ1B is not expressed in murine liver, indicating loss of μ1B expression and establishment of alternative sorting mechanisms during mammalian development

Herança de resistência do feijão-caupi ao Cowpea aphid-borne mosaic virus
The objective of this work was to evaluate the inheritance of resistance to Cowpea aphid-borne mosaic virus (CABMV) in cowpea (Vigna unguiculata). The study was performed between parental genotypes IT85F-2687 (resistant) and 'BR-14 Mulato' (susceptible), generating F1, F2, and F7 populations and backcrosses with both parental genotypes. CABMV was inoculated on plants from all generations, which were then evaluated through visual inspection and description of characteristic symptoms. A chi-square test was performed after the phenotypic classification of all plants. A segregation proportion of 1:3 (resistant:susceptible) in population F2 and of 1:1 in population F7 was accepted, showing a recessive monogenic inheritance.O objetivo deste trabalho foi avaliar a herança de resistência ao Cowpea aphid-borne mosaic virus (CABMV) em feijão-caupi (Vigna unguiculata). O estudo foi realizado entre os genótipos parentais IT85F-2687 (resistente) e 'BR-14 Mulato' (suscetível), tendo-se obtido populações F1, F2 e F7 e retrocruzamentos com ambos os genótipos parentais. O CABMV foi inoculado nas plantas de todas as gerações, que foram, então, avaliadas por inspeção visual e pela descrição dos sintomas característicos. O teste do qui‑quadrado foi aplicado após a classificação fenotípica de todas as plantas. Uma proporção de segregação de 1:3 (resistente:suscetível) na população F2 e de 1:1 na população F7 foi aceita, tendo indicado herança monogênica recessiva

Variable but consistent pattern of Meningioma 1 gene (MN1) expression in different genetic subsets of acute myelogenous leukaemia and its potential use as a marker for minimal residual disease detection
Meningioma 1 (MN1) gene overexpression has been reported in acute myeloid leukaemia (AML) patients and identified as a negative prognostic factor. In order to characterize patients presenting gene overexpression and to verify if MN1 transcript could be a useful marker for minimal residual disease detection, MN1 was quantified in 136 AML patients with different cytogenetic risk and in 50 normal controls. In 20 patients bearing a fusion gene transcript suitable for minimal residual disease quantitative assessment and in 8 patients with NPM1 mutation, we performed a simultaneous analysis of MN1 and the fusion-gene transcript or NPM1 mutation during follow-up. Sequential MN1 and WT1 analysis was also performed in 13 AML patients lacking other molecular markers. The data obtained show that normal cells consistently express low levels of MN1 transcript. In contrast, high levels of MN1 expression are present in 47% of patients with normal karyotype and in all cases with inv(16). MN1 levels during follow-up were found to follow the pattern of other molecular markers (fusion gene transcripts, NPM1 and WT1). Increased MN1 expression in the BM during follow up was always found to be predictive of an impending hematological relapse

Higher resolution physical numerical model of the Mediterranean Sea in the Copernicus Marine Service
INGV is responsible for the operational production of the physical component of the Mediterranean Sea Monitoring and Forecasting Centre (Med-MFC) of the Copernicus Marine Service Monitoring System (CMEMS).
The system was implemented in 2000 by the INGV National Group of Operational oceanography (GNOO) and has been developed in years thanks to a number of European projects.
The Med-MFC is a coupled hydrodynamic-wave model with data assimilation component with a resolution of 1/16°.
The model solutions are corrected by the variational assimilation (based on a 3DVAR scheme) of Temperature and Salinity vertical profiles (from ARGO, CTD, XBT and Gliders observations) and along track satellite Sea Level Anomaly (SLA) observations.
In order to meet the requirements for Copernicus Marine Service Phase I the increase of the horizontal (to 1/24°) and vertical resolution of the hydrodynamic component of Med-MFC has been planned.
The major improvements expected from this development are the following: 1) to better resolve the mesoscale processes in the Mediterranean region where the Rossby radius of deformation is about 12-15 km (1/24° is about 4-5 km); 2) to resolve the tidal forcing at Gibraltar, entering from the Atlantic into the Mediterranean, known to provide about 30% amplitude of the tidal signal in the Mediterranean; 3) to better resolve vertical mixing processes.UnpublishedIstituto Nazionale di Geofisica e Vulcanologia.
