Magnetism in Herbig Ae/Be stars and the link to the Ap/Bp stars

, 2007
International audienceAmong the A/B stars, about 5% host large-scale organised magnetic fields. These magnetic stars show also abundance anomalies in their spectra, and are therefore called the magnetic Ap/Bp stars.

Neutralization of the PTX3/CD44 axis suppresses TGF‐β1 signaling in kidney fibrosis

FEBS Letters, EarlyView.
This study investigates how the PTX3/CD44 axis promotes kidney fibrosis by activating TGF‐β1 signaling. We demonstrate that the neutralizing antibody WHC‐001 effectively inhibits this pathway, suppressing myofibroblast activation and partial epithelial–mesenchymal transition (EMT).

Kepler observations of rapidly oscillating Ap, δ Scuti and γ Doradus pulsations in Ap stars

, 2010
Publisher's Version/PDFObservations of the A5p star KIC 8677585 obtained during the Kepler 10-d commissioning run with 1-min time resolution show that it is a rapidly oscillating Ap (roAp) star with several frequencies with periods near 10 min.

Long period Ap stars discovered with TESS data [PDF]

, 2020
Context. The TESS space mission has a primary goal to search for exoplanets around bright, nearby stars. Because of the high precision photometry required for the main mission, it also is producing superb data for asteroseismology, eclipsing binary stars,

Inhibition of dipeptidyl peptidase 7 impairs lysophagy in LLOMe‐treated HepG2 cells

FEBS Letters, EarlyView.
DPP7 inhibition delays ubiquitin‐dependent lysophagy by attenuating ubiquitin accumulation and the recruitment of SQSTM1 and LC3 to damaged lysosomes, resulting in delayed clearance of damaged lysosomes and impaired restoration of lysosomal homeostasis. Created using FigureLabs (Certificate ID: FL‐PUB‐20260922‐Z99XNX).

Can the Anomalous Magnetic Braking of Ap/Bp Stars Explain the Orbital Decay of Algol-type Binaries?

The Astrophysical Journal
Several Algol-type binaries were detected to be experiencing rapid orbital decay, which is in contradiction with the conservative mass transfer model. In this work, we investigate whether anomalous magnetic braking (MB) of intermediate-mass Ap/Bp stars ...

Unlocking new information in stellar circular polarisation with second-order least-squares deconvolution

Astronomy & Astrophysics
Context. Least-squares deconvolution (LSD) is the standard technique used in measuring stellar magnetic fields from circular polarisation spectra. It relies on the weak-field approximation and yields the longitudinal field alone.

The mean magnetic field modulus of Ap stars [PDF]

Astronomy and Astrophysics Supplement Series, 1997
We present new measurements of the mean magnetic field modulus of a sample of Ap stars with spectral lines resolved into magnetically split components. We report the discovery of 16 new stars having this property. This brings the total number of such stars known to 42.

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

Molecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

Helium Diffusion In Rapidly Oscillating Ap Stars [PDF]

Symposium - International Astronomical Union, 1988
Suppression of convection near the poles of magnetic A stars and inhibition of winds near the equator influence chemical composition gradients resulting from diffusion, leading to appreciable horizontal variation in the equilibrium configurations of the stars.
