Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Evidence for associated production of a Higgs boson with a top quark pair in final states with electrons, muons, and hadronically decaying τ leptons at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
Results of a search for the standard model Higgs boson produced in association with a top quark pair ( tt¯H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$) in final states with electrons, muons, and hadronically decaying τ leptons are presented.

Optimising top-quark threshold scan at CLIC using genetic algorithm

open access: yesJournal of High Energy Physics, 2021
One of the important goals at the future e + e − colliders is to measure the top-quark mass and width in a scan of the pair production threshold. However, the shape of the pair-production cross section at the threshold depends also on other model ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Search for t t ¯ H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$ production in the H → b b ¯ $$ \mathrm{H}\to \mathrm{b}\overline{\mathrm{b}} $$ decay channel with leptonic t t ¯ $$ \mathrm{t}\overline{\mathrm{t}} $$ decays in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search is presented for the associated production of a standard model Higgs boson with a top quark-antiquark pair ( t t ¯ H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$ ), in which the Higgs boson decays into a b quark-antiquark pair, in proton ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Measurement of the inclusive and differential t t ¯ $$ \overline{t} $$ γ cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e ± μ ∓, e + e − , or μ + μ − ).

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
