Antiviral and immunomodulatory interferon-beta in high-risk COVID-19 patients: a structured summary of a study protocol for a randomised controlled trial.

Objectives: The primary objective of the study is to demonstrate the efficacy of low-dose IFN-β in reducing the risk of SARS-CoV-2 recently infected elderly patients to progress towards severe COVID-19 versus control group within 28 days. Secondary objectives are: 1) To assess the reduction in Intensive Care Unit (ICU) admission in patients treated with IFN-β versus control group within 28 days of randomization 2) To assess the reduction in number of deaths in IFN- β compared to control group (day 28) 3) To evaluate the increase in proportion of participants returning to negative SARS-CoV-2 RT-PCR in IFN-β -treated versus control group at Day 14 and Day 28 4) To assess the increase in SARS-CoV-2-specific binding antibody titers in IFN-β compared to control group (day 28) 5) To assess the safety of IFN-β -treated patients versus control group TRIAL DESIGN: Randomized, Open-Label, Controlled, Superiority Phase II Study. Patients, who satisfy all inclusion criteria and no exclusion criteria, will be randomly assigned to one of the two treatment groups in a ratio 2:1 (IFN-treated versus control patients).

Repeated oral administration of low doses of silver in mice: tissue distribution and effects on central nervous system.

Background: Widespread use of silver in its different forms raises concerns about potential adverse effects after ingestion, the main exposure route for humans. The aim of this study was to investigate in CD-1 (ICR) male mice the tissue distribution and in vivo effects of 4-week oral exposure to 0.25 and 1 mg Ag/kg bw 10 nm citrate coated silver nanoparticles (AgNPs) and 1 mg Ag/kg bw silver acetate (AgAc) at the end of treatment (EoT) and after 4 weeks of recovery.

Single-arm, open label prospective trial to assess prediction of the role of ERCC1/XPF complex in the response of advanced NSCLC patients to platinum-based chemotherapy.

Background: Platinum-based therapy, combined or not with immune checkpoint inhibitors, represents a front-line choice for patients with non-small-cell lung cancer (NSCLC). Despite the improved outcomes in the last years for this malignancy, only a sub-group of patients have long-term benefit. Excision repair cross-complementation group 1 (ERCC1) has been considered a potential biomarker to predict the outcome of platinum-based chemotherapy in NSCLC.

Removal of Nitrogen and Phosphorus from Thickening Effluent of an Urban Wastewater Treatment Plant by an Isolated Green Microalga.

Microalgae are photosynthetic microorganisms and are considered excellent candidates for a wide range of biotechnological applications, including the removal of nutrients from urban wastewaters, which they can recover and convert into biomass. Microalgae-based systems can be integrated into conventional urban wastewater treatment plants (WW-TP) to improve the water depuration process. However, microalgal strain selection represents a crucial step for effective phytoremediation.

Impact of ERCC1, XPF and DNA Polymerase β Expression on Platinum Response in Patient-Derived Ovarian Cancer Xenografts.

Platinum resistance is an unmet medical need in ovarian carcinoma. Molecular biomarkers to predict the response to platinum-based therapy could allow patient stratification and alternative therapeutic strategies early in clinical management. Sensitivity and resistance to platinum therapy are partially determined by the tumor's intrinsic DNA repair activities, including nucleotide excision repair (NER) and base excision repair (BER).
