Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Identification of 30,000 White Dwarf–Main-sequence Binary Candidates from Gaia DR3 BP/RP (XP) Low-resolution Spectra

open access: yesThe Astrophysical Journal Supplement Series
White dwarf–main-sequence (WD–MS) binary systems are essential probes for understanding binary stellar evolution and play a pivotal role in constraining theoretical models of various transient phenomena.

A study of U Aquarii and the nucleosynthesis of neutrons and S-process elements in evolved stars of low mass

open access: yes, 2014
The origin of the extreme hydrogen deficiency observed in the R Coronae Borealis (RCrB) stars remains poorly understood. A likely mechanism for producing this deficiency is one whereby the original hydrogen envelope of the star is engulfed and ...

Life Cycle of a Low Mass Stars

open access: yes, 2023
In the present work, I shall explain the gravity mechanism and life cycle of a low mass Stars. For this purpose, some mathematical equations, and MATLAB Program could be used to draw the shape of a gravity as a dark fabric distortion in three dimensions ...

The birthline for low-mass stars

open access: yesThe Astrophysical Journal, 1983
Using the results of protostar theory, the locus in the Hertzsprung-Russell diagram is found where pre-main-sequence stars of subsolar mass should begin their quasi-static contraction phase and first appear as visible objects. This 'birthline' is in striking agreement with observations of T Tauri stars, providing a strong confirmation of the fact that ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

TOI-3288 b and TOI-4666 b: Two gas giants transiting low-mass stars characterised by NIRPS

open access: yesAstronomy & Astrophysics
Context. Gas giant planets orbiting low-mass stars (Teff ≲ 4600 K) are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs will enable population-level studies of their properties, offering ...

SMA and CARMA observations of young brown dwarfs in ρ Ophiuchi and Taurus

open access: yesEPJ Web of Conferences, 2011
Molecular outflows provide vital information about the earliest stages in the birth of stars, studying the molecular outflow properties is therefore crucial for understanding how stars form.

New theoretical yields of intermediate mass stars [PDF]

open access: yes, 1997
We present theoretical yields of H, 4He, 12C, 13C, 14N, and 16O for stars with initial masses between 0.8 and 8 $M_{\odot}$ and initial metallicities $Z = 0.001$, 0.004, 0.008, 0.02, and 0.04. We use the evolutionary tracks of the Geneva group up to the
