Synthesis, resolution and crystal structures of two enantiomeric rhodamine derivatives [PDF]

open access: goldActa Crystallographica Section E: Crystallographic Communications, 2017
The title molecule, rac-6′-bromo-3′-diethylamino-3H-spiro[2-benzofuran-1,9′-xanthen]-3-one, C24H20BrNO3, was synthesized and the two enantiomers which formed were separated. The structures of all three compounds were determined and compared with those of

Effect of Enamel Pre-etching with Sodium Hypochlorite Deproteinisation and Bonding Agent on Retention and Microleakage of Pit and Fissure Sealants: An In-vitro Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2021
Introduction: Sealants have proved to be one of the easiest methods of caries prevention in young permanent teeth, the placement of which is very technique sensitive. The non-invasive method of pretreating the enamel surface by deproteinising it with

In vivo nerve-specificity of rhodamines and Si-rhodamines [PDF]

open access: yesMolecular-Guided Surgery: Molecules, Devices, and Applications VI, 2020
Accidental nerve damage or transection of vital nerve structures remains an unfortunate reality that is often associated with surgery. Despite the existence of nerve-sparing techniques, the success of such procedures is not only complicated by anatomical variance across patients but is also highly dependent on a surgeon's first-hand experience that is ...

Enhancement of Skin Delivery of Drugs Using Proposome Depends on Drug Lipophilicity

open access: yesPharmaceutics, 2021
The study aims to investigate the propylene glycol-based liposomes named ‘proposomes’ in enhancing skin permeation of drugs with different physicochemical properties. Ibuprofen, tofacitinib citrate, rhodamine B, and lidocaine were loaded into proposomes.
