Predictors for treatment outcomes after corneal crosslinking for keratoconus: a validation study.

Previous research suggested that baseline corrected distance visual acuity (CDVA) and maximum keratometry (Kmax) are the predictors for effectiveness of corneal crosslinking (CXL) for keratoconus. The aim of this study was to validate the previously determined predictors in a new treatment cohort. A prospective cohort of 112 eyes in 90 consecutive patients was used to validate the results of 102 eyes in 79 patients from our previous prospective cohort.

Changes in protein dynamics of the DNA repair dioxygenase AlkB upon binding of Fe(2+) and 2-oxoglutarate.

The Escherichia coli DNA repair enzyme AlkB is a 2-oxoglutarate (2OG)-dependent Fe(2+) binding dioxygenase that removes methyl lesions from DNA and RNA. To date, nine human AlkB homologues are known: ABH1 to ABH8 and the obesity-related FTO. Similar to AlkB, these homologues exert their activity on nucleic acids, although for some homologues the biological substrate remains to be identified.
