A multi-modal multi-branch framework for retinal vessel segmentation using ultra-widefield fundus photographs

Frontiers in Cell and Developmental Biology
BackgroundVessel segmentation in fundus photography has become a cornerstone technique for disease analysis. Within this field, Ultra-WideField (UWF) fundus images offer distinct advantages, including an expansive imaging range, detailed lesion data, and

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

VIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Intelligent Real‐Time Medical Image Transmission for Healthcare‐IoT via Dual‐Stage Probabilistic Restoration and Lightweight Nonlinear Encryption

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Telemedicine and healthcare‐IoT require medical image transmission that preserves diagnostic quality and confidentiality under noise, packet loss and cyber threats. Existing methods often separate restoration from security and lack real‐time efficiency.

The Evolution in Understanding the Physiological Causes of Dyspnoea in Large Hiatal Herniation: A Narrative Review

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background The symptomatology of large hiatus hernia (LHH) has been historically poorly understood, with cardiorespiratory symptoms caused by LHH being underappreciated by clinicians. This study reports on the mechanisms of dyspnoea in LHH through a historical review of symptoms and evolved physiological literature, discussing likely causation.

Tanner stages of thelarche in relation to anthropometric and ultrasound predictors in premenarcheal girls

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
We found a close correlation between thelarche and internal genital maturation on pelvic ultrasound, paralleling Tanner breast stages and supporting the concept of correlated external and internal pubertal development. Abstract Introduction Thelarche is often the first sign of puberty initiation in girls.

Diagnostic performance and feasibility of classifying placental umbilical cord insertion during routine prenatal ultrasound

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Classification of placental umbilical cord insertion is feasible within the routine prenatal ultrasound examination, and reliably excludes abnormal insertion, although positive predictive values were low. Abstract Introduction Abnormal cord insertion (velamentous or marginal) is associated with adverse perinatal outcomes, and guidelines recommend ...

The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence ‐ OMEGA report 3

Acta Ophthalmologica, EarlyView.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age‐related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify the GA area in a monocentric study.
