Nell’ambito dell’Obiettivo Realizzativo 2.3 “Sviluppo e allestimento di sensoristica e sistemi innovativi per osservazioni dell’iterazione terra-aria per la qualità dell’aria e degli ecosistemi agro-forestali” del progetto PON I-AMICA (Infrastruttura di Alta tecnologia per il Monitoraggio Integrato Climatico-Ambientale), l’Istituto per l’Ambiente Marino Costiero del Consiglio Nazionale delle Ricerche (CNR-I.A.M.C.) di Napoli, coordinato dal dott. Vincenzo Di Fiore, ha eseguito delle prospezioni sismiche, geoelettriche ed elettromagnetiche in un’area prospiciente la foce del Fiume Volturno. Tali indagini hanno avuto come obiettivo: La valutazione dell’intrusione nelle falde acquifere di componenti idrosaline provenienti dalla vicina area costiera; Lo studio, con risoluzione metrica, della porzione superficiale (0 - 80 metri di profondità) del sottosuolo al fine di caratterizzare, in termini di spessori e di velocità di propagazione, le serie riflettive che caratterizzano l’area in esame

Dwelling Enclosure 1 In Pajchela Nucleo (Cusi Cusi, Upper San Juan River Basin, Jujuy): Changes And Continuities

En este trabajo presentamos los resultados de las excavaciones llevadas a cabo en el Recinto 1 de Pajchela Núcleo, Cusi Cusi, cuenca superior del Río Grande de San Juan y los interpretamos en términos de los diferentes modos de habitar que se sucedieron en el tiempo. A partir del análisis de la estratigrafía y los materiales recuperados proponemos que en el recinto hubo tres ocupaciones: la fundacional, con fechados en el Periodo de Desarrollos Regionales Tardío (1200-1450 D.C.) vinculada con poblaciones de la esfera Doncellas-Casabindo; una segunda, en momentos Inkaicos y Coloniales Tempranos (1450-1660 D.C.) y finalmente, una tercera, que se inicia con la institucionalización de los cambios producidos por la conquista española y continúa hasta nuestros días. Interpretamos estas ocupaciones en términos de un paisaje multitemporal, buscando generar una interpretación actual de los diferentes agentes relacionados con la materialidad (comuneros/as; arqueólogos/as; turistas).In this paper we present the results of archaeological excavations conducted in Enclosure 1, Pajchela Núcleo, Cusi Cusi, upper San Juan Mayo River Basin; and we interpret them in terms of different ways of dwelling that followed in time. From stratigraphic and recovered materials analysis, we suggest that there were three occupations: the first one with dates that places it in the Late Regional Developments Period (AD 1200-1450), related with people from the Doncellas-Casabindo sphere; a second one during Inka and Early Colonial times (AD 1450-1660) and a third one that begins in the Colony and endures until today. We interpret these occupations in terms of a multi-temporal landscape, leading to the present interpretations of different agents involved in material relations (community, archaeologists, and tourists).Fil: Vaquer, Jose Maria.

Case report and summary of literature: giant perineal keloids treated with post-excisional radiotherapy

BACKGROUND: Keloids are common benign tumors of the dermis, typically arising after insult to the skin. While typically only impinging on cosmesis, large or recurrent keloids may require therapeutic intervention. While no single standardized treatment course has been established, several series report excellent outcomes for keloids with post-surgery radiation therapy. CASE PRESENTATION: We present a patient with a history of recurrent keloids arising in the absence of an ascribed trauma and a maternal familial history of keloid formation, whose physical examination several large perineal keloids of 6-20 cm in the largest dimension. The patient was treated with surgical extirpation and adjuvant radiation therapy. Radiotherapy was delivered to the scar bed to a total dose of 22 Gy over 11 daily fractions. Acute radiotherapy toxicity necessitated a treatment break due to RTOG Grade III acute toxicity (moderate ulceration and skin breakdown) which resolved rapidly during a 3-day treatment break. The patient demonstrated local control and has remained free of local recurrence for more than 2 years. CONCLUSION: Radiotherapy for keloids represents a safe and effective option for post-surgical keloid therapy, especially for patients with bulky or recurrent disease

Book Reviews

With the observation of high-energy astrophysical neutrinos by the IceCube Neutrino Observatory, interest has risen in models of PeV-mass decaying dark matter particles to explain the observed flux. We present two dedicated experimental analyses to test this hypothesis. One analysis uses 6 years of IceCube data focusing on muon neutrino ‘track’ events from the Northern Hemisphere, while the second analysis uses 2 years of ‘cascade’ events from the full sky. Known background components and the hypothetical flux from unstable dark matter are fitted to the experimental data. Since no significant excess is observed in either analysis, lower limits on the lifetime of dark matter particles are derived: we obtain the strongest constraint to date, excluding lifetimes shorter than $10^{28}$ s at 90% CL for dark matter masses above 10 TeV

Differential limit on the extremely-high-energy cosmic neutrino flux in the presence of astrophysical background from nine years of IceCube data

We report a quasi-differential upper limit on the extremely-high-energy (EHE) neutrino flux above $5\times 10^{6}$ GeV based on an analysis of nine years of IceCube data. The astrophysical neutrino flux measured by IceCube extends to PeV energies, and it is a background flux when searching for an independent signal flux at higher energies, such as the cosmogenic neutrino signal. We have developed a new method to place robust limits on the EHE neutrino flux in the presence of an astrophysical background, whose spectrum has yet to be understood with high precision at PeV energies. A distinct event with a deposited energy above $10^{6}$ GeV was found in the new two-year sample, in addition to the one event previously found in the seven-year EHE neutrino search. These two events represent a neutrino flux that is incompatible with predictions for a cosmogenic neutrino flux and are considered to be an astrophysical background in the current study. The obtained limit is the most stringent to date in the energy range between $5 \times 10^{6}$ and $5 \times 10^{10}$ GeV. This result constrains neutrino models predicting a three-flavor neutrino flux of $E_\nu^2\phi_{\nu_e+\nu_\mu+\nu_\tau}\simeq2\times 10^{-8}\ {\rm GeV}/{\rm cm}^2\ \sec\ {\rm sr}$at$10^9\ {\rm GeV}$. A significant part of the parameter-space for EHE neutrino production scenarios assuming a proton-dominated composition of ultra-high-energy cosmic rays is excluded.Comment: The version accepted for publication in Physical Review

A Search for Neutrino Emission from Fast Radio Bursts with Six Years of IceCube Data

We present a search for coincidence between IceCube TeV neutrinos and fast radio bursts (FRBs). During the search period from 2010 May 31 to 2016 May 12, a total of 29 FRBs with 13 unique locations have been detected in the whole sky. An unbinned maximum likelihood method was used to search for spatial and temporal coincidence between neutrinos and FRBs in expanding time windows, in both the northern and southern hemispheres. No significant correlation was found in six years of IceCube data. Therefore, we set upper limits on neutrino fluence emitted by FRBs as a function of time window duration. We set the most stringent limit obtained to date on neutrino fluence from FRBs with an $E^{-2}$ energy spectrum assumed, which is 0.0021 GeV cm$^{-2}$ per burst for emission timescales up to \textasciitilde10$^2$ seconds from the northern hemisphere stacking search.Comment: 15 pages, 9 figure

Double-blind, 12 month follow-up, placebo-controlled trial of mifepristone on cognition in alcoholics: the MIFCOG trial protocol

Background: Increased levels of cortisol during acute alcohol withdrawal have been linked to cognitive deficits and depression. Preclinical research found that the glucocorticoid Type II receptor antagonist, mifepristone, prevented some of the neurotoxic effects of withdrawal and memory loss. Clinical trials have shown mifepristone effective in the treatment of depression. This study aims to examine the extent to which the glucocorticoid Type II receptor antagonist, mifepristone, when given to alcohol dependent males during the acute phase of alcohol withdrawal, will protect against the subsequent memory loss and depressive symptoms during abstinence from alcohol. Methods/Design: The study is a Phase 4 therapeutic use, “Proof of Concept” trial. The trial is a double-blind randomised controlled clinical trial of mifepristone versus inactive placebo. The trial aims to recruit 120 participants referred for an inpatient alcohol detoxification from community alcohol teams, who meet the inclusion criteria; 1) Male, 2) Aged 18–60 inclusive, 3) alcohol dependent for 5 or more years. A screening appointment will take place prior to admission to inpatient alcohol treatment units to ensure that the individual is suitable for inclusion in the trial in accordance with the inclusion and exclusion criteria. On admission participants are randomised to receive 600 mg a day of mifepristone (200 mg morning, afternoon and evening) for 7 days and 400 mg for the subsequent 7 days (200 mg morning and evening) or the equivalent number of placebo tablets for 14 days. Participants will remain in the trial for 4 weeks (at least 2 weeks as an inpatient) and will be followed up at 3, 6 and 12 months post randomisation. Primary outcome measures are cognitive function at week 3 and 4 after cessation of drinking and symptoms of depression over the 4 weeks after cession of drinking, measured using the Cambridge Neuropsychological Test Automated battery and Beck Depression Inventory, respectively. Secondary outcome measures are severity of the acute phase of alcohol withdrawal, alcohol craving, symptoms of protracted withdrawal and maintenance of abstinence and levels of relapse drinking at follow-up. Discussion: The current trial will provide evidence concerning the role of glucocorticoid Type II receptor activation in cognitive function and depression during acute alcohol withdrawal and the efficacy of treatment with mifepristone
