Divergent Evolution of Radial Metallicity Gradients in the Thin and Thick Disks of the Milky Way

open access: yesThe Astrophysical Journal Letters
Using 200,388 red clump stars from LAMOST and APOGEE, we investigate the radial metallicity gradients of the Galactic disk as a function of vertical height and stellar age. The thin disk displays a pronounced negative radial metallicity gradient near the

Optimization of seminal extracellular vesicle isolation protocols for cancer biomarker analysis using proteomic profiling

open access: yesMolecular Oncology, EarlyView.
This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

The Infant Milky Way [PDF]

open access: yes, 2012
We investigate the physical properties of the progenitors of today living Milky Way-like galaxies that are visible as Damped Lyα Absorption systems and Lyα Emitters at higher redshifts (z ≍ 2.3,5.7).

The Milky Way Tomography with Subaru Hyper Suprime-Cam: Possible Implications for the Past Orbit of the Large Magellanic Cloud

open access: yesThe Astrophysical Journal Letters
We report the discovery of diffuse stellar substructure in the outer halo of the Milky Way (MW) toward Boötes, unveiled by deep imaging data of the Subaru/Hyper Suprime-Cam.

Bar Formation in Milky Way type Galaxies

open access: yesOpen Astronomy, 2016
Many barred galaxies, possibly including the Milky Way, have cusps in their centers. There is a widespread belief, however, that the usual bar instability, which occurs in bulgeless galaxy models, is impossible for cuspy models because of the presence of

4MOST Consortium Survey 3: Milky Way disc and bulge low-resolution survey (4MIDABLE-LR)

open access: yes, 2019
The mechanisms of the formation and evolution of the Milky Way are encoded in the orbits, chemistry and ages of its stars. With the 4MOST MIlky way Disk And BuLgE Low-Resolution Survey (4MIDABLE-LR) we aim to study kinematic and chemical substructures in

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Constraining the formation of the Milky Way: Ages

open access: yesEPJ Web of Conferences, 2013
We present a new approach for studying the chemodynamical evolution of the Milky Way, which combines a thin disk chemical evolution model with the dynamics from N-body simulation of a galaxy with properties similar to those of our Galaxy.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Formation Of The Milky Way

open access: yes, 2007
We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New ground- and space-based studies of globular star clusters and dwarf spheroidal galaxies provide a wealth of information to constrain ...
