Molecules in stellar atmospheres
, 1998 The effects of molecules on model stellar atmospheres are briefly reviewed. Molecular diagnostics of stellar fundamental parameters and of atmospheric structure are discussed, and the presently emerging "ISO picture" of the outer regions of stars is ...

Molecular Oncology, EarlyView.This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Molecular Oncology, EarlyView.The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

LINE FORMATION IN SPECTRA OF X-RAY NOVAE
Odessa Astronomical Publications, 2017 Results of X-ray Novae (XN) optical spectra computation are presented. The continuum and Balmer line are calculated. The model of XN as a self-irradiated accretion disk is used.

Stellar X-ray heating of planet atmospheres
, 2006 Aims.To investigate the effects of the stellar X-ray irradiation on planet atmospheres, we study the X-ray transfer and energy deposition in a hydrogen rich gas.

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy
Molecular Oncology, EarlyView.LCOR (Ligand‐dependent corepressor) mRNA encapsulated in polymeric nanoparticles restores LCOR activity in tumor cells, constraining aggressive tumor cell states and increasing tumor immunogenicity. This reprogramming makes tumor cells more vulnerable to T‐cell attack and enhances their response to immune‐checkpoint immunotherapy.

Primordial Lithium from Globular Cluster Turnoff Stars: M13 and M71
The Astrophysical JournalDuring Big Bang nucleosynthesis (BBN) in the first 15 minutes of the Universe, some ^7 Li was created along with isotopes of H and He. The determination of that primordial value of Li can help constrain the conditions at that time.

Stark Widths of Ar II Spectral Lines in the Atmospheres of Subdwarf B Stars
Atoms, 2017 Stark broadening parameters are of interest for many problems in astrophysics and laboratory plasmas investigation. Ar II spectral lines are observed in many kinds of stellar atmospheres such as the atmospheres of B-Type stars and subdwarf B stars.

Characterization of stellar and sub-stellar atmospheres [PDF]
, 2016 In this work I aim characterize a number of (sub)-stellar companions. When studying isolated brown dwarfs, very low-mass stars, and directly imaged exoplanets with insignificant orbital motion, we have to rely on theoretical models to determine basic parameters such as mass, age, and consequently, effective temperature and surface gravity.

On Stellar Models with Blanketed Atmospheres as Boundary Conditions
, 2007 The impact on the predicted Teff scale of using the latest MARCS model atmospheres, instead of a fixed atmospheric structure (e.g., the gray T–τ relation) is examined.
