On the identification and evolution of intermediate- and high-mass star forming regions across different galactic environments

open access: yes
May2026This work presents three projects investigating where intermediate-mass stars form, how unexplored evolutionary trends in star-formation may result in difficulties distinguishing them from high-mass star forming regions, and how they may be ...

The Impact of External Radiation on the Inner Disk Chemistry of Planet Formation

open access: yesThe Astrophysical Journal
The vast majority of young stars hosting planet-forming disks exist within clustered environments, like the Orion Nebula, implying that seemingly “extreme” UV environments (10 ^4 G _0 and above) are not so atypical in the context of planet formation ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Star Forming Regions in Cassiopeia

open access: yes, 2008
This chapter describes the Galactic star forming regions in the constellation Cassiopeia, in the Galactic coordinate range 120 deg < l < 130 deg, -5 deg < b < +15 deg. At b > 10 deg the nearby clouds L1333 and L1340 are found in this region.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Metal-poor Gas Accretion Drives Giant Clump Formation at 0.6 < z < 2.6

open access: yesThe Astrophysical Journal
The physical properties of kiloparsec-scale clumps in high-redshift star-forming galaxies (SFGs) contain crucial constraints on how they assemble. Building on recent work that indicates the presence of a metallicity offset in clumpy galaxies compared to ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Ultracool dwarfs in open clusters and star-forming regions

open access: yes, 2013
In this contribution I review the results of the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) on the Initial Mass Function (IMF) and the current searches for young T dwarfs in open clusters and star-forming ...

Large-scale Mapping Observations of DCN and DCO+ toward Orion KL

open access: yesThe Astrophysical Journal
We present emission maps ( $1\buildrel{\,\prime}\over{.} 5\,\times \,1\buildrel{\,\prime}\over{.} 5$ scale, corresponding to 0.18 pc) of the DCN ( J = 2 − 1) and DCO ^+ ( J = 2 − 1) lines in the 2 mm band toward the Orion KL region obtained with the 2 mm
