Malacofauna dei fondi incoerenti del Golfo di Manfredonia
No full textA study of molluscan fauna from the soft bottoms off Gulf of Manfredonia (Adriatic Sea) allowed three
different species associations to be recognized. The first at about 20 m depth, on sandy-muddy bottoms,
characterized by the bivalve Corbula gibba, the second at 50-70 m depth, on terrigenous muds, characterized
by the gastropod Turritella communis and the third, at about 100 m, on muddy costal detritic bottoms,
characterized by bivalves Nucula sulcata and Thyasira biplicata
Voltage control system for a Multigap Resistive Plate Chambers telescope
No full textMultigap Resistive Plate Chambers (MRPCs) are gas detectors operating in avalanche saturated mode at a standard voltage ranges around 18 ÷ 20 kV, applied by means of DC Low Voltage to DC High Voltage converters (DC/DC converters). This device is used in the Extreme Energy Events Project (EEE Project), an innovative experiment to study high energy cosmic rays by using a network of tracking detectors, located across the Italian territory plus CERN, over a total area of 10^5 km^2. Each EEE telescope is composed of three MRPCs. A suitable device to supply and control voltage and current for the DC-DC converters and for the MRPCs front-end cards has been developed. This electronic module is interfaced with the DAQ computer, controlled by a dedicated software in LabVIEW and, since computer is permanently online, the LV/HV system can be continuously monitored from remote

Adenocarcinoma of the cervix associated with a neuroendocrine small cell carcinoma of the cervix in the spectrum of Muir-Torre syndrome
No full textMuir-Torre syndrome (MTS) is an autosomal genodermatosis that is diagnosed by the presence of at least one sebaceous gland tumor and at least one visceral malignancy. The most frequent visceral malignancies reported in literature are low-grade colon-rectal and genitourinary cancers, with prolonged survival. The authors report the case of a 52-year-old female, with a positive familial history for MTS, who developed a cutaneous sebaceous carcinoma, a synchronous colon-rectal adenocarcinoma, and a metachronous endocervical adenocarcinoma associated with a neuroendocrine small cell carcinoma of the cervix (SCNC), with lymph node metastasis. The rare occurrence in literature of the cervical SCNC and the rarest occurrence of a neuroendocrine carcinoma in the context of a MTS deviate from the usual and low-grade types of cancers normally described with MTS. It should be always appropriate to assess any symptoms that might reveal an underlying malignancy, although not within the spectrum of neoplasms most associated with this rare syndrome
Cutaneous mastocytosis combined with eruptive melanocytic nevi and melanoma. Coincidence or a linkage in the pathogenesis?
No full textBackground: Cellular combinations in the same neoplasm can have intriguing physiopathological implications, which may be useful to better understand the biology of the diseases. Main observations: Urticaria pigmentosa in association with eruptive melanocytic nevi was observed in a female patient. Maculopapular lesions extended at the base of different melanocytic nevi and the histopathological examination revealed the presence of a mast cell population in the papillary and reticular dermis combined with overlying melanocytic nevi. The re-evaluation of a melanoma removed three years before revealed the presence of the same pathological features. Immunohistochemical assays showed a strong positivity to Giemsa, Toluidine blue and CD-117 in the mast cells, while a S-100 reaction was observed in the melanocytic population. Conclusions: We discuss possible pathogenetic linkage between cutaneous mastocytosis and melanoma
Size evaluation of Delectopecten vitreus (Mollusca, Bivalvia) from Santa Maria di Leuca deep-water coral site (Ionian Sea).
No full textThe size of a Mediterranean population of the deep sea pectinid Delectopecten vitreus (Mollusca, Bivalvia) is discussed with respect to Atlantic counterparts. The Mediterranean specimens collected in the Ionian Sea at the Santa Maria di Leuca deep water coral site are characterized by a size smaller than Atlantic stocks
