Aging and Color Vision: A Model Using the Farnsworth‐MUNSELL 100‐Hue Test

open access: yesColor Research &Application, EarlyView.
ABSTRACT Introduction This study examined the theoretical changes in the FM100 Hue scores induced by age‐related changes in the ocular media transmittance. These changes were analyzed with and without a von Kries‐type chromatic adaptation to determine the role of this adaptation process on age‐related changes in hue discrimination.

Topology-based deep-learning segmentation method for deep anterior lamellar keratoplasty (DALK) surgical guidance using M-mode OCT data [PDF]

open access: yesarXiv
Deep Anterior Lamellar Keratoplasty (DALK) is a partial-thickness corneal transplant procedure used to treat corneal stromal diseases. A crucial step in this procedure is the precise separation of the deep stroma from Descemet's membrane (DM) using the Big Bubble technique.

Elp1 function in placode‐derived neurons is critical for proper trigeminal ganglion development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The trigeminal nerve is the largest cranial nerve and functions in somatosensation. Cell bodies of this nerve are positioned in the trigeminal ganglion, which arises from the coalescence of neural crest and placode cells. While this dual cellular origin has been known for decades, the molecular mechanisms controlling trigeminal ...

Computational models for generating microvascular structures: Investigations beyond medical imaging resolution

open access: yesWIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023
Abstraction of the formation of new vascular connections through angiogenesis. Abstract Angiogenesis, arteriogenesis, and pruning are revascularization processes essential to our natural vascular development and adaptation, as well as central players in the onset and development of pathologies such as tumoral growth and stroke recovery.
