Listerin Alleviates Alzheimer's Disease through IRE1‐mediated Decay of TLR4 mRNA
Advanced Science, Volume 12, Issue 32, August 28, 2025.Alzheimer's disease (AD) progression is influenced by microglia‐mediated neuroinflammation. Here, it is demonstrated that Listerin suppresses neuroinflammatory signaling and cognitive impairment in AD models by triggering IRE1α‐mediated TLR4 mRNA decay. Adenoviral Listerin delivery reduces amyloid‐β pathology, positioning it as a new therapeutic target.

Radio line and continuum observations of quasar-galaxy pairs and the origin of low reshift quasar absorption line systems [PDF]
, 1990 There are a number of known quasars for which our line of sight to the high redshift quasar passes within a few Holmberg radii of a low redshift galaxy.

Self-mixing interference effects in tunable diode laser absorption spectroscopy [PDF]
, 2009 We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...

Galactic-scale Emission-line Outflow from the Radio-loud Quasar 3C 191
The Astrophysical Journal Supplement SeriesQuasar feedback is routinely invoked as an indispensable ingredient in galaxy formation models. Galactic outflows are a crucial agent of quasar feedback that frequently manifest themselves in absorption and emission lines.

A synoptic survey of narrow quasar absorption lines from the Sloan Digital Sky Survey [PDF]
, 2011 Repeat spectroscopic observations from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) provide an unprecedented opportunity to study the properties of thousands of quasar absorption lines (QALs) in the time domain.

Unified model for quasar absorption line systems
, 2001 We propose a three component model consisting of minihalos and galactic halos with embedded thin discs for absorbers producing all the observed classes of intervening quasar absorption line systems.
