Discrete Approaches to Quantum Gravity in Four Dimensions

open access: yesLiving Reviews in Relativity, 1998
The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. One ansatz to try to obtain a non-trivial quantum theory proceeds via a discretization of space-time and the

Downregulation of sST2, a decoy receptor for interleukin‐33, enhances subcutaneous tumor growth in murine pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Subcutaneous implantation of murine Panc02 pancreatic cancer cells depleted of sST2, a soluble decoy receptor for the proinflammatory interleukin‐33 (IL‐33), leads to a decreased number of GLUT4‐positive cancer‐associated adipocytes, reduced levels of the anti‐inflammatory molecule adiponectin, increased phosphorylation of IκBα, elevated Cxcl3 ...

Testing General Relativity with Pulsar Timing

open access: yesLiving Reviews in Relativity, 2003
Pulsars of very different types, including isolated objects and binaries (with short- and long-period orbits, and white-dwarf and neutron-star companions) provide the means to test both the predictions of general relativity and the viability of alternate

Statins induce monocytic differentiation in acute myeloid leukemia cells through the KLF4/DPYSL2A axis

open access: yesFEBS Open Bio, EarlyView.
Statins, identified via the Comparative Toxicogenomics Database, promote monocytic differentiation and apoptosis in non‐APL AML cells by upregulating DPYSL2A through a KLF4‐dependent pathway. Mevalonate supplementation reversed these effects, indicating involvement of the mevalonate pathway.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.
