Animal liberation, American anti-terrorist culture and Denis Hennelly’sBold Native

2016

ABSTRACTSince its birth in the last quarter of the twentieth century, the animal liberation movement has attempted to expose the transnational, global character of speciecism and institutionalised forms of exploitation. Within the American panorama, however, the “war against terror” following 9/11 had such a profound effect on (radical) activism at a legal and legislative level that the movement found itself in the position of having to reassess their focus, leading to theoretical and aesthetic responses to anti-terrorist rhetoric. The aim of this article is (1) to examine the manner by which anti-terrorist rhetoric affected the movement and how the movement appropriated such rhetoric to re…

Dating archaeological strata in the Magna Mater temple using solid-state voltammetric analysis of leaded bronze coins

2017

[EN] The application of solid state electrochemistry techniques for dating archaeological strata using lead-containing bronze coins is described. The proposed methodology was applied to samples coming from the Roman archaeological site of Magna Mater Temple (Rome, Italy) occurring in different strata dating back between the second half and the end of the 4(th) century A.D. and the 20(th) century. The voltammetric signatures of copper and lead corrosion products in contact with aqueous acetate buffer, as well as the catalytic effects produced on the hydrogen evolution reaction, were used for establishing the age of different strata and dating coins belonging to unknown age. Voltammetric data…

Data from: Minor environmental concentrations of antibiotics can modify bacterial virulence in co-infection with a non-targeted parasite

2018

Leakage of medical residues into the environment can significantly impact natural communities. For example, antibiotic contamination from agriculture and aquaculture can directly influence targeted pathogens, but also other non-targeted taxa of commensals and parasites that regularly co-occur and co-infect the same host. Consequently, antibiotics could significantly alter interspecific interactions and epidemiology of the co-infecting parasite community. We studied how minor environmental concentration of antibiotic affects the coinfection of two parasites, the bacterium Flavobacterium columnare and the fluke Diplostomum pseudospathaceum, in their fish host. We found that antibiotic in feed…

The Influence of Infection and Colonization on Outcomes in Inpatients With COVID-19 : Are We Forgetting Something?

2021

The COVID-19 epidemic has been a great challenge to health systems and especially hospitals. A prospective observational epidemiological study was planned as of February 26, 2020 in a tertiary hospital in the Valencia region. The total number of patients followed up with complete information during the first year was 2,448. Among other variables, the comorbidities of the patients were collected (and grouped in the Charson index), the stay in the intensive care unit (ICU), the co-infections, and the colonizations. Data on nosocomial infections due to said virus were also collected. The median days from the onset of symptoms to diagnosis were 4 + 4.6, while an additional 4.4 days had to pass …

Obtaining information on expectations among dental students regarding their career planning was the main purpose of this observational online survey. The questionnaire was designed with 18 items in five different languages: English, French, German, Italian and Spanish. Data were collected on nationality, age, sex, country of residence, university attended, semester, expected year of graduation and expectations about future career. More than 3000 participants (n = 3851, 2863 females 74.34% and 988 males 25.66% with a sex ratio of 0.35) participated in the survey. Almost one-third (31.29%) of the participants plan to start their own practice at least three years after vocational training, a q…

Direct antiviral agents in hepatitis C virus related liver disease: Don’t count the chickens before they’re hatched

2021

Since molecules with direct-acting antiviral (DAA) became available, the landscape of the treatment of hepatitis C virus (HCV) infection has completely changed. The new drugs are extremely effective in eradicating infection, and treatment is very well tolerated with a duration of 8-12 wk. This review aims to report the outstanding clinical benefits of DAA and to highlight their critical disadvantages, identifying some clinically relevant hot topics. First, do the rates of virological response remain as high when patients with more advanced cirrhosis are considered? Large studies have shown slightly lower but still satisfactory rates of response in these patients. Nevertheless, modified sche…

Direct-acting antiviral-based therapy for chronic hepatitis C virus in HIV-infected patients

2015

The aim of this review was to detail the current therapies and treatments for chronic hepatitis C virus in coinfected patients, focusing on HCV antiviral agents currently used in practice today or scheduled to enter the open market soon. Several direct-acting antiviral (DAA) combinations show high sustained virologic response (SVR) rates in HIV/HCV-coinfected patients, which are often close to those observed in HCV-monoinfected patients. Most recommendations regarding treatment stem from trials with coinfected patients. However, data are lacking for some aspects of HCV-treatment in coinfection, so extrapolations must be made from data obtained predominately from monoinfected patients. HIV/H…

Associated Factors and Liver Disease Severity for Decreased Bone Mineral Density in HIV Mono- and HIV/HCV Co-infected Patients

2015

Objective: We assessed the prevalence and risk factors of decreased bone mineral density (BMD) in patients mono-infected with human immunodeficiency virus (HIV) or co-infected with hepatitis C virus (HIV/HCV). We also evaluated whether bone loss was linked to lipid asset in both groups and to severity of liver fibrosis in the co-infected group. Methods: We consecutively enrolled 194 HIV-patients (129 mono-infected and 65 co-infected). All HIV-patients underwent dual-energy X-ray absorptiometry (DXA), while co-infected patients underwent transient elastography. Advanced liver fibrosis was defined as a median liver stiffness ≥ 9.5 kPa. Fibrosis was also assessed in all the HIV-patients using …

Phosphorus-Chalcogen Ring Expansion and Metal Coordination

2017

The reactivity of 4-membered (RPCh)2 rings (Ch = S, Se) that contain phosphorus in the +3 oxidation state is reported. These compounds undergo ring expansion to (RPCh)3 with the addition of a Lewis base. The 6-membered rings were found to be more stable than the 4-membered precursors, and the mechanism of their formation was investigated experimentally and by density functional theory calculations. The computational work identified two plausible mechanisms involving a phosphinidene chalcogenide intermediate, either as a free species or stabilized by a suitable base. Both the 4- and 6-membered rings were found to react with coinage metals, giving the same products: (RPCh)3 rings bound to the…

Ripostigli “misti” dalla Sicilia centro-meridionale

2011

It is remarkable the discovery in the hinterland of Sicily of three “mixed” hoards, including not only coins, but also of bronze scraps and small fragmentary objects. They demonstrate that in these centers, still in the 4th century BC, the coin was considered a worthless piece of metal and that other bronze objects were used as medium of exchange. The subject of further study is the so-called closet of Milocca-Milena (IGCH 2162), which is attributed to the site of Monte Raffe
