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 ...

Nebular abundances of nearby southern dwarf galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2003
The results of optical spectroscopy of H II regions in a sample of southern dwarf irregulars consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor group, and eight additional dwarf galaxies are presented. Oxygen abundances are derived using the direct method where [O III]4363 is detected; otherwise, abundances are ...

Exploring the Gas-phase Metallicity Gradients of Star-forming Galaxies at Cosmic Noon

open access: yesThe Astrophysical Journal
We explore the relationships between the [O/H] gas-phase metallicity radial gradients and multiple galaxy properties for 238 star-forming galaxies at 0.6 < z < 2.6 selected from the CANDELS Ly α Emission at Reionization survey with stellar mass $8.5\lt ...

Evidence for multiple crossings and stripping of Gaia-Enceladus/Sausage across the Milky Way

open access: yesAstronomy & Astrophysics
Context. The accretion of Gaia-Enceladus/Sausage (GES) onto the Milky Way (MW) is one of the most prominent features of the Galactic halo revealed by the combination of the Gaia satellite and large spectroscopic surveys.

Chemical behavior of the Dwarf Irregular Galaxy NGC 6822. Its PN and HII region abundances

open access: yes, 2009
We aim to derive the chemical behavior of a significant sample of PNe and HII regions in the irregular galaxy NGC 6822 The selected objects are distributed in different zones of the galaxy.

Sulphur in the Sculptor dwarf spheroidal galaxy - Including NLTE corrections [PDF]

open access: yes, 2015
In Galactic halo stars, sulphur has been shown to behave like other $\alpha$-elements, but until now, no comprehensive studies have been done on this element in stars of other galaxies.

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

open access: yesPeople and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Abundance gradients and galaxy formation

open access: yesThe Astrophysical Journal, 1991
A three-dimensional collisionless code is used to simulate the formation of elliptical galaxies with a time scale for star formation comparable to the collapse time. A one-zone chemical evolution scheme is used to compute the evolution of the abundances of several chemical elements.
