Fundamental Parameters for Central Stars of 103 Infrared Bow Shock Nebulae

The Astrophysical Journal
Stellar bow shock nebulae are arcuate shock fronts formed by the interaction of radiation-driven stellar winds and the relative motion of the ambient interstellar material.

H II regions in peculiar galaxies

The Astrophysical Journal, 1975
A survey of 32 galaxies, either classified as peculiar or having peculiar distributions of H ii regions, is presented in order to ascertain the range of the peculiarities and the degree to which they are similar. Ten different types are recognized, several of which are interrelated.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

The MDW Hα Sky Survey: Data Release 1

The Astronomical Journal
The Mittelman–di Cicco–Walker (MDW) H α Sky Survey is an autonomously operated all-sky narrowband (3 nm) H α imaging survey. The survey was founded by amateur astronomers, and the northern sky (decl.

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Consistent Gas-phase C/O Abundances from UV and Optical Emission Lines: A Robust Scale for Chemical Evolution across Cosmic Time

The Astrophysical Journal
The carbon-to-oxygen (C/O) abundance ratio is a valuable tracer of star formation history, as C and O enrichment occurs on different timescales. However, measurements based on ultraviolet (UV) collisionally excited lines and those based on optical ...
