Intratympanic Lipopolysaccharide Elevates Systemic Fluorescent Gentamicin Uptake in the Cochlea.

Laryngoscope 2021 May 6. Epub 2021 May 6.

Research Service, VA Loma Linda Healthcare System, Loma Linda, California, U.S.A.

Objectives/hypothesis: Lipopolysaccharide (LPS), a key component of bacterial endotoxins, activates macrophages and triggers the release of inflammatory cytokines in mammalian tissues. Recent studies have shown that intratympanic injection of LPS simulates acute otitis media (AOM) and results in morphological and functional changes in the inner ear. Here we established an AOM mouse model with LPS to investigate the uptake of ototoxic gentamicin in the inner ear, and elucidated the underlying mechanism by focusing on cochlear inflammation as a result of AOM.

Rhesus monkeys as a translational model for late-onset Alzheimer's disease.

Aging Cell 2021 May 5:e13374. Epub 2021 May 5.

Division of Geriatrics, Department of Medicine, SMPH, Madison, WI, USA.

Age is a major risk factor for late-onset Alzheimer's disease (AD) but seldom features in laboratory models of the disease. Furthermore, heterogeneity in size and density of AD plaques observed in individuals are not recapitulated in transgenic mouse models, presenting an incomplete picture. We show that the amyloid plaque microenvironment is not equivalent between rodent and primate species, and that differences in the impact of AD pathology on local metabolism and inflammation might explain established differences in neurodegeneration and functional decline.

Distractor filtering is affected by local and global distractor probability, emerges very rapidly but is resistant to extinction.

Atten Percept Psychophys 2021 May 4. Epub 2021 May 4.

Center for Mind/Brain Sciences (CIMeC), University of Trento, Trento, Italy.

Effects of statistical learning (SL) of distractor location have been shown to persist when the probabilities of distractor occurrence are equalized across different locations in a so-called extinction phase. Here, we asked whether lingering effects of SL are still observed when a true extinction phase, during which the distractor is completely omitted, is implemented. The results showed that, once established, the effects of SL of distractor location do survive the true extinction phase, indicating that the pattern of suppression in the saliency map is encoded in a form of long-lasting memory.

Extracellular Polymeric Substance Protects Some Cells in an Biofilm from the Biomechanical Consequences of Treatment with Magainin 2.

Microorganisms 2021 Apr 30;9(5). Epub 2021 Apr 30.

Departments of Biology and Chemistry, Cornell College, Mount Vernon, IA 52314, USA.

Bacterial biofilms have long been recognized as a source of persistent infections and industrial contamination with their intransigence generally attributed to their protective layer of extracellular polymeric substances (EPS). EPS, consisting of secreted nucleic acids, proteins, and polysaccharides, make it difficult to fully eliminate biofilms by conventional chemical or physical means. Since most bacteria are capable of forming biofilms, understanding how biofilms respond to new antibiotic compounds and components of the immune system has important ramifications. Read More
