Tidal Stripping as the Driver of Mass Segregation in the Young Open Cluster NGC 2422

open access: yesThe Astronomical Journal
We present strong evidence that mass segregation in the young open cluster NGC 2422 (age ≈84 Myr) is primarily driven by tidal stripping. Analysis of the radial mass distribution reveals a significant overabundance of low-mass stars ( M

On the disc and halo of the milky way through a study of star clusters [PDF]

open access: yesSerbian Astronomical Journal, 2000
The subject is the metallicity and the correlation between the metallicity and spatial distribution of star clusters of the Milky Way. The open star clusters are confirmed as good indicators for the population of the galactic disc, whereas the globular ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The Velocity Dispersion Profile of Nine Open Clusters in the Solar Neighborhood

open access: yesThe Astrophysical Journal
We analyze the velocity dispersion profiles of nine open clusters in the solar neighborhood using kinematic data from Gaia DR 3, aiming to identify potential dynamical signatures of stellar-mass black holes through a comparison of theoretical and ...

Internal kinematics of open star clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1989
La cinematique interne dans 8 amas ouverts est etudiee sur des donnees des mouvements propres. La dependance de la dispersion intrinseque dans le mouvement propre sur la masse stellaire et la distance radiale du centre de l'amas est examinee. Ces dispersions sont trouvees independantes de la masse stellaire et des distances radiales pour la plupart des

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
