[Blepharitis due to Demodex: myth or reality?].

B Kamoun et al.

Journal francais d'ophtalmologie, 22(5), 525-527 (1999-07-27)

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

Accumulation mechanism for metal chalcogenide nanoparticles at Hg0 electrodes: copper sulfide example.

Damir Krznarić et al.

Analytical chemistry, 80(3), 742-749 (2008-01-11)

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

Difference in effect of sodium selenite on mercury distributions after duodenal administration of mercuric chloride and mercuric oxide.

T Endo et al.

Pharmacology & toxicology, 67(5), 431-435 (1990-11-01)

To obtain evidence for difference in the absorptive forms of HgCl2 and HgO from duodenum, the Hg distributions after the duodenal administration of HgCl2 and HgO and the effect of Na2SeO3 on their Hg distributions were compared. The Hg concentrations

Sensitive and selective sensor for biothiols in the cell based on the recovered fluorescence of the CdTe quantum dots-Hg(II) system.

Bingyan Han et al.

Analytical chemistry, 81(13), 5569-5573 (2009-06-09)

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)
