The importance of the interactions between KIRs and HLA ligands in the development of human autoimmune and viral diseases

2017

Killer immunoglobulin-like receptors (KIRs) regulate the activation of natural killer cells through their interaction with human leucocyte antigens (HLA). KIR and HLA loci are highly polymorphic, and certain KIR/HLA combinations have been found to protect against viral infections or to predispose to autoimmune disorders. In particular, some activating KIR profiles may be detrimental in autoimmune pathogenesis, and specific KIR genes may be particularly aggressive in the clearance of different microorganisms, protecting individuals in the control of a given pathogen. Here we reviewed a growing body of evidence purporting the influence of KIR polymorphism and KIR-HLA interaction in the develo…

Conceptual design of the enhanced coolant purification systems for the European HCLL and HCPB test blanket modules

2019

Abstract The Coolant Purification Systems (CPSs) is one of the most relevant ancillary systems of European Helium Cooled Lead Lithium (HCLL) and Helium Cooled Pebble Bed (HCPB) Test Blanket Modules (TBMs) which are currently in the preliminary design phase in view of their installation and operation in ITER. The CPS implements mainly two functions: the extraction and concentration of the tritium permeated from the TBM modules into the primary cooling circuit and the chemistry control of helium primary coolant. During the HCLL and HCPB-TBSs (Test Blanket Systems) Conceptual Design Review (CDR) in 2015 it was recognized the need of reducing the tritium permeation into the Port Cell #16 of ITE…

Randomised Trial of Two Different Daily Doses of Interferon-α versus Classical Therapy in Treatment-Naïve Patients with Chronic Hepatitis C.

2018

To evaluate the efficacy and tolerability of two different daily doses of interferon-α (lymphoblastoid-IFNα-N1, Wellferon®) [IFNα] for 2 months, followed by the same dose on alternate days for up to 1 year, versus administration on alternate days for 1 year. A non-blind, randomised study of outpatients with chronic hepatitis C at five centres in Sicily, Italy. Ninety-seven consecutive treatment-naive patients [72 patients with hepatitis C virus (HCV) genotype 1b infection] with histological chronic hepatitis C were included in the study and randomised to receive IFNα subcutaneously: 5 million international units (MIU) daily for 2 months, followed by the same dose on alternate days for up to…

Updated design and integration of the ancillary circuits for the European Test Blanket Systems

2019

The validation of the key technologies relevant for a DEMO Breeding Blanket is one of the main objectives of the design and operation of the Test Blanket Systems (TBS) in ITER. In compliance with the main features and technical requirements of the parent breeding blanket concepts, the European TBM Project is developing the HCLL (Helium Cooled Lithium Lead) and HCPB (Helium Cooled Pebble Bed)-TBS, focusing in this phase on the design life cycle and on R&D activities in support of the design. The TBS ancillary systems are mainly circuits devoted to the removal of thermal power and to the extraction and recovery of the tritium generated in the Test Blanket Modules. They are: • The Helium C…

Mock-up testing facilities and qualification strategy for EU ITER TBMs

2010

European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. This paper presents the experimental facilities available in Europe for the qualification tests of European TBMs. In particular, devices designed to analyze specific technological issues, for example corrosion under strong magnetic fields or tritium management and extraction, as well as large scale facility to perform integral tests are described. A preliminary overview on the qualification strategy is presented and discussed.

Randomised trial of two different daily doses of interferon-α versus classical therapy in treatment-naïve patients with chronic hepatitis C

2002

Objective: To evaluate the efficacy and tolerability of two different daily doses of interferon-α (lymphoblastoid-IFNα-N1, Wellferon®) [IFNα] for 2 months, followed by the same dose on alternate days for up to 1 year, versus administration on alternate days for 1 year. Patients and methods: A non-blind, randomised study of outpatients with chronic hepatitis C at five centres in Sicily, Italy. Ninety-seven consecutive treatment-naïve patients [72 patients with hepatitis C virus (HCV) genotype 1b infection] with histological chronic hepatitis C were included in the study and randomised to receive IFNα subcutaneously: 5 million international units (MIU) daily for 2 months, followed by the same…

Healthy eating as a strategy to achieve successful ageing: focus on Mediterranean diet and functional foods.

People want to live longer. To date, it is impossible not to grow older, but it is desirable to get older in good health, avoiding age-related disabilities. To do this, it is necessary to have a healthy lifestyle which can limit the damage caused by the environmental hazards that face us each day. In humans, healthy ageing and longevity are modulated by a fortunate interaction between genetic and environmental factors. Regarding the latter, physical activity and healthy dietary habits are the most important modifiable factors that can affect the maintenance of a healthy ageing phenotype. A feasible diet that reduces the risk of ageing-related diseases, promoting health ageing and longevity,…

Nanostructured lead-acid negative electrode with reduced graphene oxide

2021

Aim of this work is to develop a new nano-structured and nano-composite lead acid negative electrode with reduced graphene oxide (rGO). Nanostructured electrodes are fabricated by template electrodeposition of lead nanowires on a lead current collector. A polycarbonate track-etched membrane was used as a template (200 nm mean pores diameter). rGO was deposited on the nanostructured electrode from a graphene oxide (GO) dispersion in acetate buffer solution (ABS) (0.2 g/L). Potentiostatic deposition of rGO at -0.8 V vs. standard calomel electrode (SCE) was performed. Electrode with rGO was tested as negative electrode in cell with 5M sulfuric acid solution, a commercial pasted positive plate,…
