Tracing Galaxy Evolution by Their Present-Day Luminosity Function

open access: yesOpen Astronomy, 2011
Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies.

MUC1 as a Survival Effector of Radiotherapy‐Induced Epithelial Hybrid States in Basal‐Like Breast Cancer

open access: yesInternational Journal of Cancer, EarlyView.
Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

Star Formation and Magnetic Field Amplification due to Galactic Spirals

open access: yesThe Astrophysical Journal
We use global MHD galaxy simulations to investigate the effects of spiral arms on the evolution of magnetic fields and star formation within a self-regulated interstellar medium.

Arbuscular mycorrhizal fungal community abundance, functions, and symbiotic interactions revealed by root metatranscriptomes

open access: yesiMetaOmics, EarlyView.
Paradigm shift: PCR‐free methods reveal 6–15‐fold higher arbuscular mycorrhizal (AM) fungal abundance than metabarcoding, exposing systematic underestimation across decades of research. Predictive power: AM fungal abundance serves as a community‐level trait that predicts crop yield under drought conditions.

Cosmological Constraints from Galaxy Clustering and the Mass-to-Number Ratio of Galaxy Clusters: Marginalizing over the Physics of Galaxy Formation

open access: yes, 2013
Many approaches to obtaining cosmological constraints rely on the connection between galaxies and dark matter. However, the distribution of galaxies is dependent on their formation and evolution as well as the cosmological model, and galaxy formation is ...

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

open access: yesiMetaOmics, EarlyView.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.

SNe feedback and the formation of elliptical galaxies

open access: yes, 2006
The processes governing both the formation and evolution of elliptical galaxies are discussed by means of a new multi-zone photo-chemical evolution model for elliptical galaxies, taking into account detailed nucleosynthetic yields, feedback from ...

Progress of metabolomics‐centric multi‐omics research in medicine

open access: yesiMetaOmics, EarlyView.
The graphical abstract illustrates a holistic roadmap for metabolomics‐centric multi‐omics integration in medical research. The upper panel depicts the technological transition from traditional bulk analysis to high‐resolution single‐cell and spatial methodologies, specifically addressing inherent challenges such as molecular complexity and dynamic ...

Quantifying Bursty Star Formation in Dwarf Galaxies

open access: yesThe Open Journal of Astrophysics
Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than ~100 Myr should lead to discontinuous

Formation and Evolution of E+A Galaxies in Dusty Starburst Galaxies

open access: yesThe Astrophysical Journal, 2001
The formation and evolution of the ``E+A'' (also named ``k+a'' and ``a+k'' types by Dressler et al. 1999) galaxies found in significant numbers in the cores of intermediate redshift clusters has been extensively discussed by many authors. In this paper, we model the spectral, dynamical and morphological evolution of a prime candidate for producing this
