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).

Phenotype Expansion of Malan Syndrome: New Cases and a Review of the Literature

American Journal of Medical Genetics Part A, Volume 200, Issue 8, Page 1783-1798, August 2026.
ABSTRACT Malan syndrome is an ultra‐rare overgrowth syndrome caused by pathogenic variants or deletions in nuclear factor one X (NFIX) located at 19p13.2. Here, we report a comprehensive literature review and phenotyping of known patients with Malan syndrome and present a novel cohort of eight patients.

Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

Acta Ophthalmologica, Volume 104, Issue 5, Page e578-e589, August 2026.
Abstract Purpose To investigate changes in choroidal and retinal thickness before and during myopia control treatment with orthokeratology lenses (OKL) in myopic children. Methods This was a sub‐study of CONTROL and CONTROL2 studies. The present study was a 2‐year, prospective, single‐group interventional study consisting of a 6‐month pre‐treatment ...

Comprehensive Assessment of the KDM2B‐Associated Neurodevelopmental Disorder and the 12q24.31 Microdeletion Syndrome

Clinical Genetics, Volume 110, Issue 2, Page 150-164, August 2026.
We set out to characterize genotype–phenotype correlations in the recently delineated KDM2B‐associated neurodevelopmental disorder. We observe a highly penetrant CxxC domain‐related phenotype with distinct facial features supported by GestaltMatcher. In contrast, our findings point to variable expressivity and incomplete penetrance of loss‐of‐function ...

Barriers to Ophthalmologic Care Reported by Family Caregivers of Users and Non‐Users With Intellectual Disabilities

Journal of Intellectual Disability Research, Volume 70, Issue 8, Page 845-857, August 2026.
ABSTRACT Background People with intellectual disabilities (IDs) are more likely to experience vision‐related impairments, yet they face many barriers to accessing eye care. Although previous studies have described these barriers, few have compared barriers reported by families who have and have not accessed ophthalmologic care, which may provide ...

Outcomes of Femtosecond Laser-Assisted Arcuate Keratotomy in the Management of Keratoplasty-Related Astigmatism [PDF]

Background/Objectives: Post-keratoplasty astigmatism can limit visual recovery even after successful corneal transplantation. Femtosecond laser-assisted arcuate keratotomy (FSAK) has emerged as a method to reduce high residual astigmatism and enhance ...

Cross‐Scale Synergistic Optimization for Miniature Meta‐Liquid Hybrid Zoom Imaging

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A physically constrained optimization framework links electrowetting liquid lenses and metasurface dispersion engineering to realize a compact visible‐band achromatic zoom imager. By co‐optimizing zoom actuation, meta‐atom manufacturability, and system aberrations, the design achieves 1.5x zoom in a 15.5 mm track and clarifies robustness against ...
