Horizontal and Vertical BIM Interoperability Aimed at Seismic Vulnerability Assessment

A vital task of this millennium is to protect the existing heritage, also through the adoption of resilient management systems. In this framework, the organization of knowledge remains one of the critical points. For this reason, new methodologies and cross-disciplinary technologies are increasingly being chosen to optimize resources toward more sustainable interventions. Therefore, the ability to model the building geometry and behavior must be maximized through interoperable processes between Building Information Modeling and Finite Element Modeling methods aimed at the seismic vulnerability assessment. Setting up an integrated digitalization process is undoubtedly challenging initially but returns more significant benefits during the infrastructure life cycle. The interoperability tests' bi-directionality is essential for constantly evaluating activities to update data following facilities' modifications. The Modal Assurance Criterion indicator is used to assess the coherence of the models after possible simplifications introduced for non-linear state analyses

Antiulcer Activity of Salvadora persica on Experimental ASA-Induced Ulcer in Rats: Ultrastructural Modifications

The lyophilized decoction of Salvadora persica L. roots possesses a significant protective effect on ulceration induced by ethanol, indomethacin and cold restraint stress in rats. In this work, we study the effect of chronic intragastric administration of S. persica decoction on experimental acetylsalicylic acid (ASA)-induced ulcer in rats. The ulcer index significantly decreased (U.I. 0.9 ± 1.6; P < 0.05) after treatment with a lyophilized decoction of S. persica (500 mg/kg, os), once daily for seven days, with respect to controls (U.I. 11.4 ± 2.3). The modification of gastric mucosa was observed by transmission electronic microscopy (TEM) confirming this result. In fact, in treated rats, the mucosa recovered to normal distribution. After S. persica treatment, some changes were detected in profiles of various cytoplasm organelles of parietal cells. Particularly, the intracellular canaliculi show an enlarged lumen with an increase in the number and length of microvilli. These morphological features of ..

Dasabuvir and Ombitasvir/Paritaprevir/Ritonavir with or without Ribavirin in Patients with HIV-HCV Coinfection. Real Life Interim Analysis of an Italian Multicentre Compassionate Use Program

Background and Aims: An HCV cure is now possible in a large proportion of HIV-HCV patient. We present real life results of a compassionate use program promoted by SIMIT (Infectious and Tropical Diseases Italian Society) of Dasabuvir and Ombitasvir/Paritaprevir/Ritonavir ± Ribavirin for 12 weeks in 213 HIV-HCV genotype 1 patients. Data on efficacy and tolerability of this strategy in HIV patients have been reported until now only in 43 non cirrhotic HIV subjects

Impact of social determinants on antiretroviral therapy access and outcomes entering the era of universal treatment for people living with HIV in Italy

Background: Social determinants are known to be a driving force of health inequalities, even in high income countries. Aim of our study was to determine if these factors can limit antiretroviral therapy (ART) access, outcome and retention in care of people living with HIV (PLHIV) in Italy. Methods: All ART naïve HIV+ patients (pts) of Italian nationality enrolled in the ICONA Cohort from 2002 to 2016 were included. The association of socio-demographic characteristics (age, sex, risk factor for HIV infection, educational level, occupational status and residency area) with time to: ART initiation (from the first positive anti-HIV test), ART regimen discontinuation, and first HIV-RNA &lt; 50 cp/mL, were evaluated by Cox regression analysis, Kaplan Meier method and log-rank test. Results: A total of 8023 HIV+ pts (82% males, median age at first pos anti-HIV test 36 years, IQR: 29-44) were included: 6214 (77.5%) started ART during the study period. Women, people who inject drugs (PWID) and residents in Southern Italy presented the lowest levels of education and the highest rate of unemployment compared to other groups. Females, pts aged &gt; 50 yrs., unemployed vs employed, and people with lower educational levels presented the lowest CD4 count at ART initiation compared to other groups. The overall median time to ART initiation was 0.6 years (yrs) (IQR 0.1-3.7), with a significant decrease over time [2002-2006 = 3.3 yrs. (0.2-9.4); 2007-2011 = 1.0 yrs. (0.1-3.9); 2012-2016 = 0.2 yrs. (0.1-2.1), p &lt; 0.001]. By multivariate analysis, females (p &lt; 0.01) and PWID (p &lt; 0.001), presented a longer time to ART initiation, while older people (p &lt; 0.001), people with higher educational levels (p &lt; 0.001), unemployed (p = 0.02) and students (p &lt; 0.001) were more likely to initiate ART. Moreover, PWID, unemployed vs stable employed, and pts. with lower educational levels showed a lower 1-year probability of achieving HIV-RNA suppression, while females, older patients, men who have sex with men (MSM), unemployed had higher 1-year risk of first-line ART discontinuation. Conclusions: Despite median time to ART start decreased from 2002 to 2016, socio-demographic factors still contribute to disparities in ART initiation, outcome and durability

Matching microscopic and macroscopic responses in glasses

We first reproduce on the Janus and Janus II computers a milestone experiment that measures the spin-glass coherence length through the lowering of free-energy barriers induced by the Zeeman effect. Secondly we determine the scaling behavior that allows a quantitative analysis of a new experiment reported in the companion Letter [S. Guchhait and R. Orbach, Phys. Rev. Lett. 118, 157203 (2017)]. The value of the coherence length estimated through the analysis of microscopic correlation functions turns out to be quantitatively consistent with its measurement through macroscopic response functions. Further, non-linear susceptibilities, recently measured in glass-forming liquids, scale as powers of the same microscopic length.Comment: 6 pages, 4 figure
