KILLING THE CURE? Is targeting LIF to treat pancreatic cancer a dangerous case of mistaken identity?

open access: yesMedicine in Drug Discovery, 2022
Leukaemia Inhibitory Factor (LIF) is a stem cell growth factor critical to health. LIF belongs to the IL-6 family of cytokines but LIF-signalling is unique and qualified by its cell surface receptor, LIF-R.

A miscibility gap in LiF–BeF2 and LiF–BeF2–ThF4 [PDF]

open access: yesJournal of Nuclear Materials, 2005
LiF–BeF2 and LiF–BeF2–ThF4 are key systems for Molten Salt Reactor fuel. The liquid phase of these systems has been assessed using Redlich–Kister polynomials. The result shows a miscibility gap on the BeF2-rich side. This has never been proven experimentally. Nevertheless, evidence for a two liquids region is given by the fact that such a region exists
