New Objective Refraction Metric Based on Sphere Fitting to the Wavefront

Journal of Ophthalmology, 2017
Purpose. To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil ...

Interocular differences in visual quality due to ocular aberrations and scattering in a patient with post-traumatic anisocoria: A case report

Journal of Optometry, 2012
A 41-year-old patient with visual disturbances after an ocular trauma in right eye three years before was carefully analyzed and discussed. No corneal or intraocular sequelae were present. Only a significant anisocoria could be observed.

Cooperative role of MDSCs and Tregs in alum-induced alloimmune tolerance in corneal transplantation

Scientific Reports
Alum, a widely used adjuvant, has recently been recognized for its capacity to modulate immune responses beyond classical activation. In this study, we investigated whether alum-induced expansion of myeloid-derived suppressor cells (MDSCs) and their ...

Ocular comorbidities and its relation to clinical and dermoscopic features in patients with alopecia areata: a case-control study

Journal of the Egyptian Women’s Dermatologic Society
Background Alopecia Areata (AA) is considered a systemic autoimmune disease that can be associated with several comorbidities. Several ocular alterations have been previously reported in patients with AA.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...
