General description
Yellow mercuric oxide shows antibacterial property and is commonly used in ophthalmic ointments.
Application
Yellow mercuric oxide in the presence of mercuric bromide catalyst may be used in the preparation of alkyl β-D-glucopyranoside tetra-O-acetates and tetra-O-benzoates from poly-O-acyl-α-D-glucopyranosyl bromides and different alcohols via Koenigs-Knorr syntheses.

Treatment of peptides with excess HgO in the presence of alkaline cyanide leads to cleavage of the peptides at glycine residues. The reaction appears to involve both C- and N-mercuration with subsequent release of 2 mol mercury per mol of

Herein, a sensitive and selective sensor for biothiols based on the recovered fluorescence of the CdTe quantum dots (QDs)-Hg(II) system is reported. Fluorescence of QDs could be quenched greatly by Hg(II). In the presence of biothiols, such as glutathione (GSH)

Demodex folliculorum has been incriminated in the development of blepharitis although much controversy persists. Certain authors suggest that Demodex is a direct pathogen in chronic palpebral conditions while others consider the saprophyte to be innocuous to skin. We conducted a
