Ultrasound findings in a case of Eales’ disease and ocular trauma with anterior chamber cholesterolosis

open access: yesBMC Ophthalmology, 2020
Background Anterior chamber cholesterolosis is a rare phenomenon which occurs mostly in chronically blind eyes. We present the anterior and posterior ultrasound findings in a case of anterior chamber cholesterolosis secondary to Eales’ disease and ocular

Evaluation of ocular blood flow by Doppler ultrasound in patients with essential blepharospasm

open access: yes, 2021
Purpose Benign essential blepharospasm (EB) is a focal facial dyskinesia that occurs with the involuntary contraction of muscles around the eyes. In the literature, studies on blepharospasm focus on elucidating the pathophysiology of this condition in ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

open access: yesAdvanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Ultrasonographic assessment of optic nerve and optic nerve sheath diameters with ocular biometry in brachycephalic versus non-brachycephalic cats [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi
Distinct craniofacial morphology in brachycephalic cats may alter ocular anatomy and predispose these breeds to specific ophthalmic conditions. This study evaluated the relationship between craniofacial conformation and optic nerve diameter (OND), optic ...
