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

18-Hydroxy-6,19-oxidoprogesterone and 18-hydroxy-11, 19-oxidoprogesterone were synthesized from readily available materials. The functionalization of C-18 was accomplished with phenyliodosodiacetate/iodine, whereas that of C-19 was carried out with the mercuric oxide/iodine system, both under irradiation with visible light. For 18-hydroxy-11,19-oxidoprogesterone, C-19 was

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

We report on a patient who had an excessive number of mites (Demodex folliculorum) on his eye lashes, i.e. 10 mites on eight lashes examined. A review of three previous reports suggested that one mite for every two lashes represents

Mercury electrodes preconcentrate metal chalcogenide nanoparticles effectively, enabling their detection at submicromolar concentrations (as Sigma chalcogenide) by adsorptive cathodic stripping voltammetry. Understanding the unique behavior of nanoparticle analytes during preconcentration is critical for lowering detection limits and for quantification. A
