Planetary nebulae in the inner Milky Way [PDF]

, 2009
New abundances of planetary nebulae located towards the bulge of the Galaxy are derived based on observations made at LNA (Brazil). We present accurate abundances of the elements He, N, S, O, Ar, and Ne for 56 PNe located towards the galactic bulge.

Chemodynamical simulations of the Milky Way galaxy [PDF]

, 2011
We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from oxygen to zinc.

The Three-phase Evolution of the Milky Way

The Astrophysical Journal
We illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a sample of 10 million red giant stars with full chemodynamical information, including metallicities and α -abundances from low-resolution Gaia XP spectra.

Targeting EZH2 reverses thyroid cell dedifferentiation and enhances iodide uptake in anaplastic thyroid cancer

FEBS Letters, EarlyView.
Anaplastic thyroid cancer (ATC) lacks iodide uptake ability due to MAPK activation increasing the expression of the histone methyltransferase EZH2, which represses thyroid differentiation genes (TDGs) such as the sodium iodide symporter (NIS). Dual inhibition of MAPK (U0126) and EZH2 (EPZ6438/Tazemetostat) reverses this mechanism, thus restoring TDG ...

Predicting the locations of possible long-lived low-mass first stars: Importance of satellite dwarf galaxies

, 2017
The search for metal-free stars has so far been unsuccessful, proving that if there are surviving stars from the first generation, they are rare, they have been polluted, or we have been looking in the wrong place.

Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models

The Astrophysical Journal
The circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Outer Regions of the Milky Way

, 2017
With the start of the Gaia era, the time has come to address the major challenge of deriving the star formation history and evolution of the disk of our MilkyWay. Here we review our present knowledge of the outer regions of the Milky Way disk population.

The inhibitory SAPS3–AMPK interaction detected in HEK293 cells is not detectable in muscle or liver from humans or mice

FEBS Letters, EarlyView.
This study challenges the idea that Sit4‐associated protein subunit 3 (SAPS3) inhibits the energy‐sensing enzyme AMP‐activated protein kinase (AMPK) in muscle and liver tissue. Although SAPS3 interacts with AMPK in cultured cells, we found no such interaction in human or mouse tissues subjected to fasting, exercise, or a high‐fat diet.

VISTA Milky Way public survey [PDF]

, 2009
We propose a public IR variability survey, named \Vista Variables in the Vía Láctea" (V V V ), of the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. This would take 1920 hours, covering ~ 109 point sources
