Perspectives in educating molecular pathologists on liquid biopsy: Toward integrative, equitable, and decentralized precision oncology

Molecular Oncology, EarlyView.
Liquid biopsy enables minimally invasive, real‐time molecular profiling through analysis of circulating biomarkers in biological fluids. This Perspective highlights the importance of training pathologists through integrative educational programs, such as the European Masters in Molecular Pathology, to ensure effective and equitable implementation of ...

Extended Stellar Populations in Ultrafaint Dwarf Galaxies

The Astronomical Journal
The possible existence of stellar halos in low-mass galaxies is being intensely discussed nowadays after some recent discoveries of stars located in the outskirts of dwarf galaxies of the Local Group.

The stellar to sub-stellar masses transition in 47 Tuc

Astronomy & Astrophysics
Context. The study of the globular cluster 47 Tuc offers an opportunity to shed new light on the debated issue of the presence of multiple populations in globular clusters, as recent results from HST photometry and high-resolution spectroscopy outlined ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

oMEGACat. IV. Constraining the Ages of Omega Centauri Subgiant Branch Stars with HST and MUSE

The Astrophysical Journal
We present age estimates for over 8100 subgiant branch (SGB) stars in Omega Centauri ( ω Cen) to study its star formation history. Our large data set, which combines multi-wavelength Hubble Space Telescope photometry with MUSE metallicities, provides an ...

Next‐generation proteomics improves lung cancer risk prediction

Molecular Oncology, EarlyView.
This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

On the Origin of Neutron-capture Elements in r-I and r-II Stars: A Differential-abundance Analysis

The Astrophysical Journal
We present a strictly line-by-line differential analysis of a moderately r -process-enhanced star ( r -I: HD 107752) with respect to a strongly r -process-enhanced star ( r -II: CS 31082-0001) to investigate the possible common origin of their heavy ...

Galaxy interactions in void substructures: Morphology and stellar populations of two triplets from CAVITY

Astronomy & Astrophysics
Context. Cosmic voids, vast, underdense regions of the Universe, serve as unique laboratories for studying galaxy evolution in isolation. Within these voids, galaxy triplets, rare systems of three close galaxies, provide crucial insights into how local ...
