The Fluctuation Theory of the Stellar Mass Loss [PDF]

International Astronomical Union Colloquium, 1981
That we cannot give a justification – or sufficient reasons – for our guesses does not mean that we may not have guessed the truth.K.R. PopperIf studied in detail, the mass flows from the stars appear to be variable. “Mere inspection of solar wind data reveals large variations on a time scale of several days” (Hundhausen, 1972).

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 ...

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

On stellar mass loss from galaxies in groups and clusters [PDF]

, 2017
We estimate the stellar mass that satellite galaxies lose once they enter groups (and clusters) by identifying groups in a high-resolution cosmological N-body simulation, assigning entry masses to satellite galaxies with halo abundance matching at the ...

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

A stellar-mass black hole population in the globular cluster NGC 6101? [PDF]

, 2016
Dalessandro et al. observed a similar distribution for blue straggler stars and main-sequence turn-off stars in the Galactic globular cluster NGC 6101, and interpreted this feature as an indication that this cluster is not mass-segregated. Using direct N-

The Stellar Morphology and Size of X-Ray-selected Active Galactic Nucleus Host Galaxies Revealed by JWST

The Astrophysical Journal
We investigate the stellar shape and size–mass relationship of X-ray-selected active galactic nucleus (AGN) host galaxies using the high angular resolution and deep sensitivity in the near-infrared of the COSMOS-Web JWST survey field. We present the rest-

Stellar Mass and Stellar Mass-to-light Ratio–Color Relations for Low Surface Brightness Galaxies

The Astronomical Journal, 2020
Abstract We estimate the stellar mass for a sample of low surface brightness galaxies (LSBGs) by fitting their multiband spectral energy distributions (SEDs) to the stellar population synthesis model. The derived stellar masses (log M */M ⊙) span from 7.1 to 11.1, with a mean of log M

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Galaxy metallicities depend primarily on stellar mass and molecular gas mass [PDF]

, 2016
In this work we present an analysis of the behaviour of galaxies in a four-dimensional parameter space defined by stellar mass, metallicity, star formation rate, and molecular gas mass.
