AMPK‐Dependent Epigenetic Regulation of Metabolism Mediates the Anti‐Cancer Action of Pterostilbene in Hepatocellular Carcinoma

Molecular Nutrition &Food Research, EarlyView.
This study investigates the anti‐cancer effects of pterostilbene (PTS), a naturally occurring dietary phytoestrogen, in a rat model of hepatocellular carcinoma (HCC) induced by a choline‐deficient L‐amino acid‐defined (CDAA) diet. Supplementation with PTS significantly reduces liver steatosis and tumor formation.

The Growth of Galaxy Stellar Haloes over 0.2 ≤ z ≤ 1.1

The Astrophysical Journal
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass ...

The relation between bar formation, galaxy luminosity, and environment

, 2013
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

Sex‐Specific Lasting Metabolome Effects of Adverse Gestational Conditions and Prevention by Myo‐Inositol Supplementation During Suckling

Molecular Nutrition &Food Research, EarlyView.
This graphical abstract illustrates the effects of myo‐inositol supplementation during suckling in reducing long‐term metabolic impacts from mild gestational calorie restriction (GCR). Using a metabolomics approach, 164 metabolites were identified, with greater metabolic alterations in males.

Chloroplast genome of the critically endangered Ginger Zingiber odoriferum Blume from Java, Indonesia: characterization, comparison, and conservation insights

Nordic Journal of Botany, EarlyView.
Zingiber odoriferum (Zingiberaceae), a critically endangered ginger species endemic to Java, Indonesia, is ecologically vital yet genomically understudied. We present the first complete chloroplast (cp) genome (163 538 bp), revealing a quadripartite structure with a large single‐copy region (88 033 bp), a small single‐copy region (15 885 bp), and a ...

JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon

The Astrophysical Journal Letters
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon—the peak of cosmic star formation history—appear disk-dominated, leaving the origin of the dense cores in their quiescent descendants unclear.

On the Possibility of Determining the Distance to the Galactic Center from the Geometry of Spiral Arm Segments

Open Astronomy, 2015
A new approach to determining the solar galactocentric distance, R0, from the geometry of spiral-arm segments is proposed. Geometric aspects of the problem are analyzed and a simplified three-point method for estimating R0 from objects in a spiral ...

Betaine‐Conjugated ß‐Peptide Foldamers: Influence of Quaternary Charge on Self‐Organization and MorphologyFormation

ChemistryOpen, EarlyView.
N‐terminal betaine conjugation modifies β‐peptide helices, influencing folding and self‐organization. For [1S, 2S]‐ACPC, folding to an H12 helix was unaffected, while [1R, 2R]‐ACHC formed an H14 helix instead of H10. Alternating heterochiral oligomers made of enantiomeric pairs of trans‐ACPC showed enhanced solubility and E‐strand formation.

IllustrisTNG in the HSC-SSP: No Shortage of Thin Disk Galaxies in TNG50

The Astrophysical Journal
We perform a thorough analysis of the projected shapes of nearby galaxies in both observations and cosmological simulations. We implement a forward-modeling approach to overcome the limitations in previous studies, which hinder accurate comparisons ...
