Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

open access: yesActa Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Solar flare forecasting using sunspot-groups classification and photospheric magnetic parameters

open access: yes, 2010
In this paper, we investigate whether incorporating sunspot-groups classification information would further improve the performance of our previous logistic regression based solar flare forecasting method, which uses only line-of-sight photospheric ...

Solar Observations by Angelo Secchi: An Analysis of His Diary and Annotations in His Sunspot Drawings

open access: yesThe Astrophysical Journal
Angelo Secchi, a pioneer in solar physics, provided an extensive and regular record of sunspot observations spanning the period 1858–1878. This study analyzes the handwritten records by Secchi and collaborators in the form of drawings and an observation ...

Harmonizing Sunspot Datasets Consistency: Focusing on SOHO/MDI and SDO/HMI Data

open access: yesUniverse
To ensure the long-term consistency of sunspot group data, it is essential to harmonize measurements from SOHO/MDI and SDO/HMI, two major solar observatories with overlapping coverage.

Adult‐onset Coats disease: A systematic review and meta‐analysis of imaging biomarkers and targeted therapies

open access: yesActa Ophthalmologica, EarlyView.
Abstract Coats disease diagnosed in adulthood is a rare idiopathic retinal telangiectatic vasculopathy that may differ in phenotype from childhood‐diagnosed cases. This systematic review synthesizes current evidence to characterize its clinical spectrum, imaging features, treatment outcomes and underlying mechanisms, with a focus on immunovascular ...

An Alternative Measure of Solar Activity from Detailed Sunspot Datasets [PDF]

open access: yes, 2016
The sunspot number is analyzed by using detailed sunspot data, including aspects of observability, sunspot sizes, and proper identification of sunspot groups as discrete entities of the solar activity.

Analyses of Johannes Kepler’s Sunspot Drawings in 1607: A Revised Scenario for the Solar Cycles in the Early 17th Century

open access: yesThe Astrophysical Journal Letters
Telescopic sunspot observations began in 1610 and captured subsequent solar cycles. In combination with proxy reconstructions on an annual scale, these data sets indicate a gradual transition between regular solar cycles and the Maunder Minimum.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Discovery of PHB1 as a Novel Candidate Gene in Dominant Optic Atrophy

open access: yesClinical Genetics, EarlyView.
A heterozygous PHB1 missense variant (p.Ser147Phe) segregates with autosomal dominant optic atrophy in a multi‐generation family. Structural and cellular analyses suggest altered mitochondrial dynamics, identifying PHB1 as a novel candidate gene for hereditary optic neuropathy. ABSTRACT Hereditary optic neuropathies comprise a genetically heterogeneous

Statistical study of the equatorial F2 layer critical frequency at Ouagadougou during solar cycles 20, 21 and 22, using Legrand and Simon’s classification of geomagnetic activity

open access: yesJournal of Space Weather and Space Climate, 2012
This paper presents the statistical analysis of the diurnal variations of the F layer at the equatorial station of Ouagadougou (Lat: 12.4° N; Long: 358.5° E; dip: 5.9°) from 1966 to 1998 (=> ~11 680 days).
