Trial Design and Endpoints in Hepatocellular Carcinoma: AASLD Consensus Conference
2020
Proper trial design is critical for the success of clinical investigations. Hepatocellular carcinoma (HCC) is a complex disease that has several unique properties. In 2008, after the approval of sorafenib, a panel of experts proposed guidelines for trial design and endpoints in HCC that have been instrumental during the last decade and provided a framework to allow an homogeneous analysis of reported investigations. Since then, several phase III studies have been reported and novel challenges have emerged. A panel of experts conveyed by AASLD organized a Special Topic Conference on trial design and endpoints to address those emerging challenges. This review summarizes the analysis and concl…
VISMapper: ultra-fast exhaustive cartography of viral insertion sites for gene therapy
2017
The possibility of integrating viral vectors to become a persistent part of the host genome makes them a crucial element of clinical gene therapy. However, viral integration has associated risks, such as the unintentional activation of oncogenes that can result in cancer. Therefore, the analysis of integration sites of retroviral vectors is a crucial step in developing safer vectors for therapeutic use. Here we present VISMapper, a vector integration site analysis web server, to analyze next-generation sequencing data for retroviral vector integration sites. VISMapper can be found at: http://vismapper.babelomics.org . Because it uses novel mapping algorithms VISMapper is remarkably faster t…
Development of a method for the direct fermentation of semolina by selected sourdough lactic acid bacteria
2016
Three obligately heterofermentative lactic acid bacteria (LAB) strains (Lactobacillus sanfranciscensis PON100336, Leuconostoc citreum PON10079 and Weissella cibaria PON10030) were used in this study as a multi-species starter culture for sourdough production. The starter inoculum was prepared and propagated in sterile semolina extract (SSE) broth. Acidification kinetics, microbiological counts detected on specific media for sourdough LAB, polymorphic profile comparison and species-specific PCRs evidenced a stability of the liquid inoculum over time determining its suitability for direct addition to semolina. In order to validate this innovative method for the production of durum wheat (Trit…
Fatty Acid Composition of Gluten-Free Food (Bakery Products) for Celiac People
2018
The aim of this study (first analytical approach) was to obtain data concerning the fatty acid composition of gluten-free foods (bakery products) for celiac people. The study included 35 different products (snacks, biscuits, bakery products, pasta, flours, etc.) from several manufacturers. After extraction and esterification, the fatty acid composition was determined by Gaschromatography (GC&ndash

Statins in liver disease: not only prevention of cardiovascular events
2018
Statins are lipid-lowering agents and one of the most pre-scribed drugs worldwide. Their main mechanism of action –inhibition of the mevalonate pathway through an effect on hydroxy-methylglutaryl CoA reductase, thus affecting the synthesis of cholesterol in the liver – makes this class of drugs pivotal in primary and secondary prevention of cardio-vascular risk, as extensively demonstrated in large prospective, randomized controlled trials. Along the years, we learned that the lower the better, and LDL-cholesterol targets have been progressively reduced to values ≤70 mg/dL for secondary prevention or in the presence of diabetes.
New 3-Aryl-2-(2-Thienyl)acrylonitriles with High Activity against Hepatoma Cells
2021
New 2-(thien-2-yl)-acrylonitriles with putative kinase inhibitory activity were prepared and tested for their antineoplastic efficacy in hepatoma models. Four out of the 14 derivatives were shown to inhibit hepatoma cell proliferation at (sub-)micromolar concentrations with IC50 values below that of the clinically relevant multikinase inhibitor sorafenib, which served as a reference. Colony formation assays as well as primary in vivo examinations of hepatoma tumors grown on the chorioallantoic membrane of fertilized chicken eggs (CAM assay) confirmed the excellent antineoplastic efficacy of the new derivatives. Their mode of action included an induction of apoptotic capsase-3 activity, whil…
Caenorhabditis elegans as an in vivo model to assess fucoidan bioactivity preventing Helicobacter pylori infection
2020
Currently, Helicobacter pylori is the unique biological carcinogenic agent. The search for antimicrobial alternatives to antibiotics against this pathogen has been categorized as a priority due to the drastic failure associated with current applied antibiotic therapy. The present study assessed the bioactive antimicrobial capability of fucoidan (“Generally Recognized as Safe” approval – European Commission December 2017) from different species of Phaeophyceae algae (Fucus vesiculosus, Undaria pinnatifida, Macrocystis pyrifera) against H. pylori. All the studied fucoidans showed bacteriostatic and bactericidal effects at the studied concentrations [5–100] μg ml−1 and exposure times [0–7 days…
Prevalence of Listeria spp. and characterization of Listeria monocytogenes isolated from food products in Tetouan, Morocco
2018
A total of 1096 food samples were purchased in Tetouan, North-Western of Morocco, to examine the presence of Listeria spp. Eighty (7.3%) of the tested samples were found positive for the presence of Listeria spp., while L. monocytogenes was detected in 16 (1.5%) samples. L. monocytogenes isolates belonged to clonal complexes CC2 (PCR serogroup IVb) and CC199 (PCR serogroup Ila) and to 8 different combined AscI/Apal pulsed-field gel electrophoresis profiles. Core genome multilocus sequence typing (cgMLST) allowed to distinguish 12 different cgMLST types and revealed the presence of 3 clusters of closely-related isolates from different samples, suggesting the existence of common sources of co…
