Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Density functional theory investigations of radical scavenging activity of 3′-Methyl-quercetin
Journal of Saudi Chemical Society, 2016 The possible eight rotamers of 3′-Methyl-quercetin have been optimized by using density functional theory (DFT) at B3LYP/6-31G∗ level of theory. The molecular structure and molecular properties of the most stable rotamers have been investigated at the ...

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome
FEBS Letters, EarlyView.In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

Autoionization in time-dependent density-functional theory [PDF]
, 2016 We compute the exact exchange-correlation potential of the time-dependent density-functional theory (TDDFT) for the correlated process of autoionization. The potential develops barriers which regulate the autoionization rate.

Antibacterial activities, DFT and QSAR studies of quinazolinone compounds
Bulletin of the Chemical Society of Ethiopia, 2016 The quinazolinone compounds (1 and 2) in this work were examined for their in vitro antibacterial activities against gram-positive (Staphylococcus aureus) and gram-negative bacteria (Klebsiella pneumonia, Proteus bacilli and Shigella flexneri).

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Geometric Time-Dependent Density Functional Theory
We provide a new formulation of Time-Dependent Density Functional Theory (TDDFT) based on the geometric structure of the set of states constrained to have a fixed density.

Time-Dependent Density Functional Theory
, 2014 The basic general concepts of time-dependent density functional theory (TDDFT) are briefly outlined before focusing on the linear response formalism in this framework (LR-TDDFT). A number of approximations and connections with other methods are discussed.
