Analysis of factors influencing refractive error in Fuchs eyes undergoing Descemet membrane endothelial keratoplasty triple procedure.

Purpose: To evaluate the accuracy of current intraocular lens (IOL) formulas and identify factors influencing mean error in eyes undergoing Descemet membrane endothelial keratoplasty (DMEK) triple procedure, that is, DMEK combined with cataract extraction and IOL placement for concurrent Fuchs endothelial corneal dystrophy (FECD) and cataracts.

Design: Retrospective cohort study.

Subjects: 90 eyes with FECD undergoing uncomplicated DMEK triple procedure at Wilmer Eye Institute.

Neritriterpenols A-G, euphane and tirucallane triterpenes from Euphorbia neriifolia L. and their bioactivity.

Euphorbia neriifolia L. is widely distributed in India, Thailand, and China and has been used to treat diseases such as rotten sores and asthma as well as for its antidiabetic and anticancer effects. In this study, seven undescribed triterpenes, including six euphanes, neritriterpenols A-B and D-G, and a tirucallane, neritriterpenol C, together with four known triterpenes, were isolated from ethanolic extracts of E.

Anti-inflammatory constituents from Hayata.

A novel chromone analogue, phyllomakin A (), and a new flavonolignan, (-)-quiquelignan C (), along with 18 phenolic and 2 triterpenoids, were isolated from the leaves of Hayata. The structures of - were elucidated by an application of various spectroscopic analyses (1D & 2D NMR and MS) and compared with reported data. A biological evaluation showed that compound had very potent anti-NO production activity (IC = 4.

Bioactive Flavonoid Glycosides and HPLC and UPLC Quantification of Commercial Astragali Complanati Semen.

Eleven compounds, including nine known flavonoid glycosides (-, -, and -), one isoflavone glycoside (), and a glansreginic acid (), were isolated from the 80% ethanol extract of commercial Astragali Complanati Semen (ACS). All chemical structures were determined by spectroscopic analyses, including 1D and 2D NMR. Compounds , , , , , and were isolated and identified from the title plant for the first time.
