Cardiovascular risk factors and their responses to a 10 weeks training program in young adult Qataris
( Openventio Publishers , 2015 , Article)Rapid development in Qatar in recent years has led to numerous changes, particularly the increased prevalence of lifestyle related health risks, with almost 50% obesity rates amongst Qataris of all ages. We investigated ... -
Carnosol induces ROS-mediated beclin1-independent autophagy and apoptosis in triple negative breast cancer
( Public Library of Science , 2014 , Article)Background: In this study we investigated the in vitro and in vivo anticancer effect of carnosol, a naturally occurring polyphenol, in triple negative breast cancer.Results: We found that carnosol significantly inhibited ... -
Case-control design identifies ecological drivers of endemic coral diseases
( Nature Research , 2020 , Article)Endemic disease transmission is an important ecological process that is challenging to study because of low occurrence rates. Here, we investigate the ecological drivers of two coral diseases growth anomalies and tissue ... -
Catalytic activity of photocharged binary TiO2 and WO3 membrane filters: Effect of Al2O3 interlayer on direct vs. mediated electron transfers
( Elsevier , 2022 , Article)One of the challenges facing the practical application of photocatalysis is the termination of catalytic reactions in the absence of irradiation. This study synthesizes photo-charged TiO2/WO3 (TW) and TiO2/Al2O3/WO3 (TAW) ... -
Catalytic C-H oxidations by nonheme mononuclear Fe(II) complexes of two pentadentate ligands: Evidence for an Fe(IV) oxo intermediate
( Elsevier , 2016 , Article)The oxidation reactions of alkanes with hydrogen peroxide and peracids (peracetic acid (PAA) and m-chloroperoxybenzoic acid (mCPBA)) catalysed by two Fe(II) complexes of pentadentate {N5}-donor ligands have been investigated. ... -
Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process
( MDPI , 2019 , Article)In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with ... -
The catalytic thermo-oxidative decomposition of glimepiride using the isoconversional method
