The coronal line region of active galactic nuclei
Frontiers in Astronomy and Space SciencesForbidden coronal lines has traditionally called the attention due to the high-energy photons required for their production (IP >100 eV, where IP is the ionisation potential of the transitions that originate the line).

Effects of Stromgren Sphere on Line Profiles of 32 CYG with Alfven Waves Driven Wind [PDF]
Journal of Astronomy and Space Sciences, 1998 We calculated line profiles of 32 Cyg with an assumed stromgren sphere at orbital phases 0.06 and 0.78. The wind models with Alfven waves show diminished line profiles compared to those of the models using power velocity laws.

Comparisons and Comments on Electron and Ion Impact Profiles of Spectral Lines
Open Astronomy, 2011 Stark broadening theory is currently operated for calculating widths and shifts of spectral lines that are needed for spectroscopic diagnostics and modeling in astrophysics, laboratory and technological plasmas. We have calculated a great number of data,

Synchrotron X-ray Diffraction Line Profile
Fizika A : a journal of experimental and theoretical physics, 1997 We analyse diffraction line profiles obtained at the X3B1 National Synchrotron Light Source powder-diffraction beamline. Calculated diffraction-line widths are compared to the measurements of a National Institute of Science and Technology Standard Reference Material, LaB6.

Effective therapeutic targeting of CTNNB1‐mutant hepatoblastoma with WNTinib
Molecular Oncology, EarlyView.WNTinib, a Wnt/CTNNB1 inhibitor, was tested in hepatoblastoma (HB) experimental models. It delayed tumor growth and improved survival in CTNNB1‐mutant in vivo models. In organoids, WNTinib outperformed cisplatin and showed enhanced efficacy in combination therapy, supporting its potential as a targeted treatment for CTNNB1‐mutated HB.

Phase- and Inclination-Dependent Line Profiles of 32 Cygni [PDF]
Journal of Astronomy and Space Sciences, 1992 The line profiles of 32 Cyg have been calculated by integrating the equation of transfer numerically. In order to determine the source function the two level atom and complete redistribution were assumed and Sobolev approximation was used.

Solar prominences line profiles
, 1994 A numerical code to calculate the line profiles for different elements present in the solar atmosphere was developed for the particular case of solar prominences. The objective is to compare the calculated with the observed profiles in order to limit the range of variation of the physical parameters, as temperature, pressure, electronic density, total ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox
