Advanced Biology, EarlyView.Coacervation driven by liquid‐liquid phase separation (LLPS) of biopolymers has garnered increasing attention in biology since this leads to the formation of membraneless organelles capable of performing essential yet largely unknown functions. This review highlights recent advances in coacervates (artificial condensates) composed of low‐molecular ...

Laser-based X-ray and electron source for X-ray fluorescence studies [PDF]
, 2016 In this work we present a modification to conventional X-rays fluorescence using electrons as excitation source, and compare it with the traditional X-ray excitation for the study of pigments. For this purpose we have constructed a laser-based source capable to produce X-rays as well as electrons.

Experimental determination of L X-ray fluorescence cross sections for elements with 45 < Z < 50 at 10 keV [PDF]
Papers in Physics 6, 060001 (2014), 2014 Synchrotron radiation at 10 keV was used to experimentally determine the Ll, L, LI, LII, LI and LII fluorescence cross sections for elements with 45 < Z < 50, as part of an ongoing investigation at low energies. The measured data were compared with calculated values obtained using coefficients from Scofield, Krause and Puri et al.

Advanced Biology, EarlyView.Hypoxia promotes the epithelial‐mesenchymal transition (EMT) of renal tubular epithelial cells via the SIRT1‐FoxO1‐FoxO3‐autophagy pathway, thereby resulting in the fibrosis of renal tubular epithelial cells. Activation of SIRT1 or induction of autophagy inhibits this process, alleviating hypoxia‐induced fibrosis.

The origin and chronology of medieval silver coins based on the analysis of chemical composition
Nukleonika, 2015 Medieval Central Europe coins - the Saxon coins, also called as the Otto and Adelheid denarii, as well as the Polish ones, the Władysław Herman and Bolesław Śmiały coins - were examined to determine their provenance and dating.
