The Second Workshop on Lineshape Code Comparison: Isolated Lines

open access: yesAtoms, 2014
In this work, we briefly summarize the theoretical aspects of isolated line broadening. We present and discuss test run comparisons from different participating lineshape codes for the 2s-2p transition for LiI, B III and NV.

Widths and Shifts of Isolated Lines of Neutral and Ionized Atoms Perturbed by Collisions With Electrons and Ions: An Outline of the Semiclassical Perturbation (SCP) Method and of the Approximations Used for the Calculations

open access: yesAtoms, 2014
“Stark broadening” theory and calculations have been extensively developed for about 50 years. The theory can now be considered as mature for many applications, especially for accurate spectroscopic diagnostics and modeling, in astrophysics, laboratory ...

Bovine annulus fibrosus cell lines isolated from intervertebral discs

open access: goldGenomics Data, 2016
The adult bovine (Bos taurus) intervertebral disc is primarily comprised of two major tissue types: The outer annulus fibrosus (AF) and the central nucleus pulposus (NP). We isolated several primary cell lineages of passage (P) 0 cells from the AF tissue

Two new jatrophane diterpenes from the roots of Euphorbia nicaeensis [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
In the previous study fifteen jatrophane diterpenes were isolated from the Euphorbia nicaeensis latex. Fourteen of them have been shown to be potent P-glycoprotein (P-gp) inhibitor in two MDR cancer cells (NCI-H460/R and DLD1-TxR).

The Semiclassical Limit of the Gailitis Formula Applied to Electron Impact Broadening of Spectral Lines of Ionized Atoms

open access: yesAtoms, 2021
The present paper revisits the determination of the semi-classical limit of the Feshbach resonances which play a role in electron impact broadening (the so-called “Stark“ broadening) of isolated spectral lines of ionized atoms. The Gailitis approximation

7-Geranyloxycinnamic Acid Isolated from Melicope lunu-ankenda Leaves Perturbs Colon Cancer and Breast Cancer Cell Lines’ Growth via Induction of Apoptotic Pathway

open access: yesMolecules, 2023
Globally, breast cancer is the most prevalent form of cancer in women and there is a need for alternative therapies such as plant-derived compounds with low systemic toxicity and selective toxicity to cancer cells.

Bis-Bibenzyls from the Liverwort Pellia endiviifolia and Their Biological Activity

open access: yesPlants, 2021
Based on previous investigations where bis-bibenzyls isolated from liverworts showed various biological activities (cytotoxic, antimicrobial, and antiviral), we investigated their cytotoxic activity in several human cancer cell lines.

Spectra of Ga-Like to Cu-Like Praseodymium and Neodymium Ions Observed in the Large Helical Device

open access: yesAtoms, 2021
Extreme ultraviolet (EUV) spectra of highly charged praseodymium (Pr) and neodymium (Nd) ions have been investigated in optically thin high-temperature plasmas produced in the Large Helical Device (LHD), a magnetically confined torus device for fusion ...
