Activity of grape extracts from Greek varieties of Vitis vinifera against mutagenicity induced by bleomycin and hydrogen peroxide in Salmonella typhimurium strain TA102
(2006)Several in vivo and in vitro studies have shown that grape extracts could prevent certain steps in carcinogenesis and a few mechanisms have been proposed for this activity. In this study, the potential antimutagenic activity ... -
Ammonia-induced inhibition of manure-based continuous biomethanation process under different organic loading rates and associated microbial community dynamics
(2021)Three Continuously Stirred Tank Reactors (CTSRs) were operating at steady state conditions with Organic Loading Rates (OLR) of 2.09, 3.024 and 4.0 g VS L−1 d−1. Glucose was used as the sole factor for increasing the OLR, ... -
The architecture of hydrogen and sulfur σ-hole interactions explain differences in the inhibitory potency of C-β-D-glucopyranosyl thiazoles, imidazoles and an N-β-D glucopyranosyl tetrazole for human liver glycogen phosphorylase and offer new insights to structure-based design
(2020)C-Glucopyranosyl imidazoles, thiazoles, and an N-glucopyranosyl tetrazole were assessed in vitro and ex vivo for their inhibitory efficiency against isoforms of glycogen phosphorylase (GP; a validated pharmacological target ... -
Blood Biomarkers and Metabolomic Profiling for the Early Diagnosis of Vancomycin-Associated Acute Kidney Injury: A Systematic Review and Meta-Analysis of Experimental Studies
(2022)Background: several blood-based biomarkers have been proposed for predicting vancomycin-associated kidney injury (VIKI). However, no systematic analysis has compared their prognostic value. Objective: this systematic review ... -
Corrosion-induced hydrogen embrittlement in aluminum alloy 2024
(2006)The present paper focuses on the observed corrosion-induced embrittlement of alloy 2024 and tries to answer the key question on whether the observed embrittlement is attributed to hydrogen uptake and trapping in the material. ... -
Crude bio-glycerol aqueous phase reforming and hydrogenolysis over commercial SiO2Al2O3 nickel catalyst
(2016)In the present work, an one-pot Aqueous Phase Reforming (APR) and Aqueous Phase Hydrogenolysis (APH) of crude glycerol in a batch reactor containing commercial SiO2Al2O3 supported 65%Ni catalyst is performed. The effect ... -
Electrocatalytic production of hydrogen over highly efficient ultrathin carbon encapsulated S, P co-existence copper nanorods composite
(2020)Electrocatalysis plays a key role in energy conversion processes (such as hydrogen evolution reaction-HER) to several renewable energy technologies developed to reduce our dependence on fossil fuels. It is of great importance ... -
A green approach for enhancing the electrocatalytic activity and stability of NiFe2O4/CB nanospheres towards hydrogen production
(2020)Among the exfoliation processes applied on layered materials, it is the first time to explore the ultrasonic exfoliation in water for improving the catalytic properties of NiFe2O4/CB (CB = carbon black) nanospheres towards ... -
Hydrogen induced shear localization of the plastic flow in metals and alloys
(2001)Hydrogen enhanced localized plasticity (HELP) is a viable mechanism for hydrogen embrittlement supported by experimental observations. According to the HELP mechanism, hydrogen induced premature failures result from hydrogen ... -
Theoretical modeling of the gas humidification effect on the characteristics of proton ceramic fuel cells
(2019)Proton ceramic fuel cells are promising electrochemical converters that produce electrical energy by oxidizing hydrogen. Understanding the impact of gas humidification on the characteristics of such fuel cells is pivotal ...
