Mirror symmetry of higher order aberrations between right and left eyes
African Vision and Eye Health, 2014 Introduction: There is evidence that certain measures of visual function show some type of relationship between right and left eyes in the same individual.

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Peripheral higher order aberrations in emmetropes and myopes [PDF]
, 2008 Purpose: Poor image quality in the peripheral field may lead to myopia. Most studies measuring the higher order aberrations in the periphery have been restricted to the horizontal visual field.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Higher order aberrations in keratoconus
Optometry in Practice, 2009 This paper describes the challenges in measuring and correcting the optical aberrations in keratoconic eyes, and reviews what has been learned from studies investigating the use of aberration-controlling contact lenses in keratoconus. At present the idea of aberration-controlling contact lenses is plausible.

THEORY OF HIGHER ORDER CHROMATIC ABERRATIONS
Acta Physica Sinica, 1980 In this article, we discuss the changes of the coordinates of the pupil and the object plane caused by the Seidel aberrations of the front groups in the optical system, and also the effect of these changes on the chromatic aberrations of the back groups, i.e., the theory of derivative higher order chromatic aberrations.

HIGHER-ORDER ABERRATIONS IN EYES WITH SILICONE OIL TAMPONADE
Retina, 2020 Purpose: To investigate the changes in higher-order aberrations (HOAs) after silicone oil removal and to evaluate their associations with visual acuity. Methods: Fifty-nine eyes of 58 patients who underwent SO removal were included.
