Phosphonofluoresceins: Synthesis, Spectroscopy, and Applications.

Joshua L Turnbull et al.

Journal of the American Chemical Society, 143(16), 6194-6201 (2021-04-03)

Xanthene fluorophores, like fluorescein, have been versatile molecules across diverse fields of chemistry and life sciences. Despite the ubiquity of 3-carboxy and 3-sulfonofluorescein for the last 150 years, to date, no reports of 3-phosphonofluorescein exist. Here, we report the synthesis

Corneal staining characteristics in limited zones compared with whole cornea documentation for the detection of dry eye subtypes.

Beau J Fenner et al.

Investigative ophthalmology & visual science, 54(13), 8013-8019 (2013-11-14)

To determine the reliability of single- and double-zone corneal fluorescent staining compared with five-zone analysis for the prediction of dry eye disease. Prospective study of 510 subjects with dry eye disease characterized using corneal fluorescein staining, Schirmer scores, and tear

Real-time measurement of solute transport within the lacunar-canalicular system of mechanically loaded bone: direct evidence for load-induced fluid flow.

Christopher Price et al.

Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research, 26(2), 277-285 (2010-08-18)

Since proposed by Piekarski and Munro in 1977, load-induced fluid flow through the bone lacunar-canalicular system (LCS) has been accepted as critical for bone metabolism, mechanotransduction, and adaptation. However, direct unequivocal observation and quantification of load-induced fluid and solute convection
