Investigating lymphangiogenesis in vitro and in vivo using engineered human lymphatic vessel networks.

Proc Natl Acad Sci U S A 2021 Aug;118(31)

Department of Biomedical Engineering, Technion - Israel Institute of Technology, Haifa 32000, Israel;

The lymphatic system is involved in various biological processes, including fluid transport from the interstitium into the venous circulation, lipid absorption, and immune cell trafficking. Despite its critical role in homeostasis, lymphangiogenesis (lymphatic vessel formation) is less widely studied than its counterpart, angiogenesis (blood vessel formation). Although the incorporation of lymphatic vasculature in engineered tissues or organoids would enable more precise mimicry of native tissue, few studies have focused on creating engineered tissues containing lymphatic vessels.

First-principles correction scheme for linear-response time-dependent density functional theory calculations of core electronic states.

J Chem Phys 2021 Jul;155(3):034108

Department of Chemistry, University of Zurich, Winterthurerstrasse 190, CH-8057 Zürich, Switzerland.

Linear-response time-dependent density functional theory (LR-TDDFT) for core level spectroscopy using standard local functionals suffers from self-interaction error and a lack of orbital relaxation upon creation of the core hole. As a result, LR-TDDFT calculated x-ray absorption near edge structure spectra needed to be shifted along the energy axis to match experimental data. We propose a correction scheme based on many-body perturbation theory to calculate the shift from first-principles. Read More
