Prevalence and Pattern of Refractive Errors Among Yanomami Indigenous People in the Brazilian Amazon: A Cross‐Sectional Observational Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Refractive errors are the leading cause of preventable visual impairment worldwide, yet data from isolated Indigenous populations remain virtually absent from the global literature. The Yanomami, one of the largest Indigenous peoples in the Americas with recent and limited contact with non‐Indigenous society, have no prior ...

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Quantitative evaluation of LED‐based optical autofocus module

Journal of Microscopy, EarlyView.
Abstract We report an improved version of the open‐source optical autofocus (OAF) module (openAF) for light microscopy, replacing the superluminescent diode (SLD) with a multimode‐optical fibre‐coupled LED as a more accessible AF module light source. We also present a method for independently quantifying AF system performance using 2D autocorrelation ...

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

American Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 2067-2079, September 2026.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

Clinical Genetics, Volume 110, Issue 3, Page 369-373, September 2026.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

USP34 Haploinsufficiency as a Cause of Neurodevelopmental Phenotypes

Clinical Genetics, Volume 110, Issue 3, Page 315-324, September 2026.
Heterozygous loss‐of‐function variants in USP34 cause a novel neurodevelopmental disorder characterized by global developmental delay, speech impairment, autism, hypotonia, craniofacial dysmorphism, and distal limb anomalies. Disrupted Wnt/β‐catenin signaling via reduced Axin stabilization refines gene‐specific contributions within 2p15p16.1 ...
