Optic nerve aplasia: A case series
Indian Journal of Ophthalmology, 2018 Optic nerve aplasia (ONA) is a congenital optic nerve anomaly characterized by the absence of optic nerve head, retinal blood vessels, retinal ganglion cells, and optic nerve fibers in a malformed eye.

Vasculature of the distal part of optic nerve [PDF]
Vojnosanitetski Pregled, 2010 Background/Aim. Vascularisation of the distal, namely intracranial and intracanalicular parts of the optic nerve have not been explained in conventional textbooks of anatomy, while there have been explanations of proximal, that is intraorbital segment ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Optic Nerve Avulsion and Retinal Detachment After Penetrating Ocular Trauma: Case Report [PDF]
, 2018 Optic nerve avulsion is a rare pathology with poor prognosis usually seen after blunt trauma. The optic nerve is separated from the sclera by indirect forces due to the relatively weak structure of the lamina cribrosa area.

FEBS Open Bio, EarlyView.KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

Bilateral Optic Nerve Enhancement in Posterior Ischemic Optic Neuropathy Secondary to Hypovolemic Shock [PDF]
, 2021 Enhancement of the optic nerve is occasionally noted in patients with arteritic ischemic optic neuropathy (ION) and non-arteritic anterior ION. We report a rare case of bilateral optic nerve enhancement in hypotension-related posterior ION (PION)

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins
FEBS Open Bio, EarlyView.Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...
