A Whole‐Head Finite Element Model for Electrical Neuromodulation via Visual Brain‐Machine Interfaces

open access: yesAdvanced Science, EarlyView.
A multimodal, personalized head model is presented that integrates the entire visual pathway with surrounding tissues to simulate electrical stimulation of the optic nerve. In vivo validation in humans and goats, plus systematic component‐elimination analysis, demonstrates the high accuracy of the comprehensive model.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

open access: yesAdvanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Advanced ring melanoma of the choroid and ciliary body with extrascleral extension

open access: yesAfrican Vision and Eye Health
Introduction: Ring melanoma is a rare form of uveal melanomas that is characterized by circumferential growth pattern. The diagnosis of ring melanomas may be delayed because of their initial hidden location and non-specific symptoms.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Histopathology and Genetic Biomarkers of Choroidal Melanoma

open access: yesApplied Sciences, 2020
Choroidal melanoma (CM), despite its rarity, is the most frequent intraocular malignancy. Over time, several histological variants of CM have been distinguished, including spindle A and B cell, fascicular, epithelioid and necrotic type.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

open access: yesThe Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Efficacy of Hand Gestures and the Hand as Foot Teaching Method Compared to Traditional Methods in Medical and Dental Education: A Scoping Review

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective The “Hand‐as‐Foot” teaching method is an innovative, hands‐on approach that uses gesture‐based movements to represent anatomical structures and functions. It has been used successfully in medical education to help simplify and communicate complex ideas. However, its use in dental education remains relatively unexplored.
