STELLAR OBJECTS OF EXTRAGALACTIC ORIGIN IN THE GALACTIC HALO

Odessa Astronomical Publications, 2007
We identified globular clusters and field stars of extragalactic origin and investigated their chemical, physical, and kinematical properties. This objects as supposed was captured by the Galaxy at different times from debris of the dwarf satellite ...

APOGEE DR14/DR15 Abundances in the Inner Milky Way

, 2018
We present an overview of the distributions of 11 elemental abundances in the Milky Way's inner regions, as traced by APOGEE stars released as part of SDSS Data Release 14/15 (DR14/DR15), including O, Mg, Si, Ca, Cr, Mn, Co, Ni, Na, Al, and K.

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Metals in Star-forming Galaxies with KCWI. I. Methodology and First Results on the Abundances of Iron, Magnesium, and Oxygen

The Astrophysical Journal
Understanding the chemical enrichment of different elements is crucial to gaining a complete picture of galaxy chemical evolution. In this study, we present a new sample of 46 low-redshift, low-mass star-forming galaxies at M _* ∼ 10 ^8−10 M _⊙ along ...

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, Volume 157, Issue 9, Page 1948-1962, 1 November 2025.
What's new? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

Deep MOS Spectroscopy of NGC 1316 Globular Clusters

Galaxies, 2017
The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

The Inclusion of Hermetia Illucens Larvae Meal in the Diet of Laying Hens (Hy‐Line Brown) Affects the Caecal Bacterial Composition and Diversity

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
This study evaluated partial replacement of soybean meal with Hermetia illucens larvae meal in laying hens’ diets. While alpha diversity was unaffected, beta diversity revealed distinct microbial profiles among treatments. A 50% replacement enriched beneficial genera (Alistipes, Parabacteroides, Butyricimonas) and reduced potentially harmful taxa ...
