Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

open access: yesAdvanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Supramolecular Modulation of Photoinduced Charge Transfer: Tuning Between Tunneling and Incoherent Hopping

open access: yesAngewandte Chemie, EarlyView.
Molecular recognition guest binding can comprehensively modulate photoinduced charge‐transfer dynamics in the cyclophane host, including charge separation and recombination, via coherent superexchange and incoherent hopping. Unlike covalent donor–bridge–acceptor systems, this supramolecular approach avoids tedious syntheses and offers precise tuning of

[Pigment formation and other biological properties of staphylococci].

open access: yesZhurnal mikrobiologii, epidemiologii i immunobiologii, 1976
A comparison was made of the pigment-forming capacity and the enzymatic activity, growth rate, virulence and sensitivity to antibiotics and egg lysozyme in 397 pigment, 203 pigment-free strains of staphylococci and 24 pigment-free Staph aureus mutants. Pigment formation did not always correlate with the general biological activity of the cultures, the ...

Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult‐Onset in a 46‐Year‐Old Male

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal
