An unattended image‐processing pipeline for on‐the‐fly quality assessment and 3D exploration in cryo‐EM

open access: yesActa Crystallographica Section D, Volume 82, Issue 8, Page 915-939, August 2026.
We present a fully automated, unattended cryo‐EM pipeline that serves as an on‐the‐fly diagnostic tool, enabling rapid data‐quality assessment and informed decision‐making to maximize data‐collection efficiency.Single‐particle analysis (SPA) by cryogenic electron microscopy (cryo‐EM) has become a cornerstone of structural biology; yet, the workflow ...

The positive correlation between the progressive photoreceptor damage and the increased macular leakage indicating the severity of diabetic retinopathy

open access: yesJournal of Diabetes Investigation, Volume 17, Issue 8, Page 1348-1357, August 2026.
The dark area of photoreceptor cells, as measured by adaptive optics laser scanning ophthalmoscopy, shows significant enlargement with the progression of diabetic retinopathy (DR). A similar trend is observed for macular vascular leakage assessed by fundus fluorescein angiography. A positive correlation exists between these two parameters, suggesting a

Prevalence and profile of astigmatism in individuals availing ophthalmic services at Central Regional Referral Hospital, Gelephu, Bhutan: A cross-sectional, hospital-based study

open access: yesBhutan Health Journal
Introduction: Astigmatism has been defined as a type of refractive error when parallel rays of light entering the eye are not focused at one point of the retina when accommodation is at rest due to irregular curvature of the cornea or lens surface.

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

open access: yesJournal 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 ...
