Published in 2020 at "Journal of Nuclear Cardiology"

DOI: 10.1007/s12350-020-02448-y

Abstract: No methodology is available to distinguish truly reduced myocardial flow reserve (MFR) in positron emission tomography myocardial perfusion imaging (PET MPI) from seemingly impaired MFR due to inadequate adenosine response. The adenosine-induced splenic switch-off (SSO)… read more here.

Published in 2019 at "International Journal of Polymeric Materials and Polymeric Biomaterials"

DOI: 10.1080/00914037.2019.1695204

Abstract: Abstract Smart hydrogels comprising carboxymethyl guar gum and polyvinyl alcohol (CMGG/PVA) were fabricated using tetraethyl orthosilicate as crosslinker. The hydrogels were subjected to nonthermal plasma (NTP) treatment using nitrogen and ammonia mixture. An improvement in… read more here.

Published in 2021 at "Frontiers in Cardiovascular Medicine"

DOI: 10.3389/fcvm.2021.719565

Abstract: Background: Phase analysis is a technique used to assess left ventricular mechanical dyssynchrony (LVMD) in nuclear myocardial imaging. Previous studies have found an association between LVMD and myocardial ischemia. We aim to assess the potential… read more here.
