Symmetry in fundamental parameters of galaxies on the star-forming main sequence

Monthly Notices of the Royal Astronomical Society
ABSTRACT The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stellar masses $M_*$ across cosmic time, for star forming galaxies.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Chemical Abundances of the Bioessential Elements C, O, and S, and the Refractory Elements Fe and Ni, in Solar-type Exoplanet-hosting Stars from HARPS North and South

The Astronomical Journal
We determined atmospheric and evolutionary parameters, along with chemical abundances of C, O, S, Fe, and Ni for 290 solar-type exoplanet-hosting stars using high-resolution HARPS-North and HARPS-South spectra, and radii for 373 exoplanets using ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Giant Planets and Eccentric Orbits are Common around Galactic Thick Disk Stars

The Astronomical Journal
Planet formation in the Galactic thick disk is expected to be inefficient—low solid reservoirs, short disk lifetimes, and harsh irradiation environments should conspire to inhibit the assembly of planetary bodies—yet, planets are there, and they are ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

BCD spectrophotometry of stars with the B[e] phenomenon : I. Fundamental Parameters [PDF]

, 2010
Low resolution spectra in the λλ3500-4600 Å wavelength range of 23 stars with the B[e] phenomenon are presented. Spectral classification of 15 program stars was performed using the BCD spectrophotometric system, based on the study of the Balmer ...

Absolute Calibration. IV. Use of G-type Stars as Primary Calibrators

The Astronomical Journal
We demonstrate an approach to determine spectral energy distribution (SED) templates that are accurate to the 1% level from the visible through the infrared for nearby (unextincted) solar-type stars. Our approach is based only on measurements of T _eff ,

Fundamental Parameters for Central Stars of 103 Infrared Bow Shock Nebulae

The Astrophysical Journal
Abstract Stellar bow shock nebulae are arcuate shock fronts formed by the interaction of radiation-driven stellar winds and the relative motion of the ambient interstellar material. Stellar bow shock nebulae provide a promising means to measure wind-driven mass loss, independent of other established methods. In this work, we characterize
