Fine structure of the red clump in Local Group galaxies [PDF]
, 1999 Some fine structures can nowadays be identified in the high-quality colour-magnitude diagrams (CMD) of Local Group galaxies. The clump of red giants, for instance, may present a significant colour spread, and extensions to both brighter and fainter ...

Molecular Oncology, EarlyView.AZD9291 has shown promise in targeted cancer therapy but is limited by resistance. In this study, we employed metabolic labeling and LC–MS/MS to profile time‐resolved nascent protein perturbations, allowing dynamic tracking of drug‐responsive proteins. We demonstrated that increased NNMT expression is associated with drug resistance, highlighting NNMT ...

Finding the unusual red giant remnants of cataclysmic variable mergers
The Open Journal of AstrophysicsMergers between helium white dwarfs and main-sequence stars are likely common, producing red giant-like remnants making up roughly a few percent of all low-mass ($\lesssim2M_\odot$) red giants.

The infrared Galactic disk: What have we learned?
EPJ Web of Conferences, 2012 A brief overview is given of some of the new insights we have achieved from the Spitzer/GLIMPSE/MIPSGAL surveys of the Galactic plane. Particular emphasis is given to infrared bubbles, rapidly accreting protostars, infrared dark clouds, and diffuse PAH ...

Evolutionary properties of stellar standard candles: Red clump, AGB clump and white dwarfs [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThe location of the white dwarf cooling sequence in the colour–magnitude diagram of simple stellar populations, the magnitude of the red clump and the magnitude of the asymptotic giant branch clump are three stellar distance indicators based on advanced evolutionary phases of low-mass stars. With the present observational capabilities, they can

Molecular Oncology, EarlyView.This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

On the Age Calibration of Open Clusters Using Red Clump Stars
The Astronomical JournalIn this study, we extend the dust-independent Hatzidimitriou relation between cluster age and d _B _− _R color difference between the red giant branch (RGB) and red clump to younger cluster ages.

Molecular Oncology, EarlyView.A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Lithium evolution in the low-mass evolved stars with asteroseismology and LAMOST spectroscopy
Fundamental ResearchLithium is an ancient element that was first produced by the Big Bang Nucleosynthesis (BBN) a few minutes after the birth of the Universe. Lithium is a sensitive tracer for a number of processes in a variety of astrophysical environments due to its multi-

The evolution of red clump stars - Theoretical sequences
The Astrophysical Journal Supplement Series, 1987 Two grids of horizontal-branch evolutionary sequences are presented which extend the grid of Sweigart and Gross (1976) to higher masses and higher metallicities. These two grids were constructed specifically for the study of red clump stars observed in intermediate-age star clusters in the Magellanic Clouds and in the Galaxy. An additional evolutionary
