The Treatment of Rosacea with Glycolic Acid
Rosacea is a common skin condition that affects an estimated 13 million Americans, with almost half of these patients between the ages of 30 and 50 years old [1]. It is a relapsing, chronic dermatosis that develops in stages and is characterized by a defect in vascular responsiveness [2,3]. Most often, fair-skinned individuals are seen first with flushing and blushing episodes followed by persi...
متن کاملStrict Anaerobes Growing with Glycolic Acid
The glycolate-oxidizing, sulfate-reducing bacterium strain PerGlyS and the syntrophically glycolate-oxidizing bacterium strain FlGlyR were studied with respect to their phylogenetic relationships on the basis of in vitro amplification and direct sequencing of 16s rRNA-encoding DNA. Strain PerGlyS clustered with representatives of the S subclass of the class Proteobacteria, close to “Desulforhop...
متن کاملChiral uranyl-organic compounds assembled with achiral furandicarboxylic acid by spontaneous resolution.
Influenced by different cations in the self-assembly of chiral units, achiral (UOC-NH4, UOC-Ca) and chiral (UOC-Na) uranyl-organic compounds were obtained from achiral reactants. The photocatalytic activity of UOC-Na was also investigated.
متن کاملOptical discrimination of racemic from achiral solutions.
The use of femtosecond laser pulses to selectively trigger an asymmetric photoreaction is demonstrated in this study. Depending on the handedness of the laser polarization, more R- or S-enantiomers of a racemate are gradually destroyed, leading to the generation of enantiomeric excess. The kinetic evolution of this excess is detected with a sensitive polarimeter. Hence, discrimination between r...
متن کاملSpecular optical activity of achiral metasurfaces
Optical activity in 3D-chiral media in the form of circular dichroism and birefringence is a fundamental phenomenon that serves as evidence of life forms and is widely used in spectroscopy. Even in 3D-chiral media exhibiting strong transmission optical activity, the reflective effect is weak and sometimes undetectable. Here we report that specular optical activity at structured interfaces can b...
