Nitric oxide synthase protein levels, not the mRNA, are downregulated in olfactory bulb interneurons of reeler mice

open access: yes, 2007
Homozygous mutations in the Reelin gene result in severe disruption of brain development. The histogenesis of layered regions, like the neocortex, hippocampus and the cerebellum, is most notably affected in mouse reeler mutants and similar traits are ...

Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

open access: yes, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned

CHARGE Syndrome: What an Otolaryngologist Should Know—A Systematic Review and Meta‐Analysis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To synthesize the prevalence of otolaryngologic manifestations in CHARGE syndrome (CS) to support otolaryngologists in delivering comprehensive management. Data Sources PubMed/MEDLINE, Embase, and Google Scholar were searched for English‐ and French‐language studies published from January 1980 through January 2025.

Reduced olfactory bulb volume accompanies olfactory dysfunction after mild SARS-CoV-2 infection

open access: yesScientific Reports
Despite its high prevalence, the determinants of smelling impairment in COVID-19 remain not fully understood. In this work, we aimed to examine the association between olfactory bulb volume and the clinical trajectory of COVID-19-related smelling ...

Applying a new version of the Brazilian-Portuguese UPSIT smell test in Brazil [PDF]

open access: yes, 2010
Standardized olfactory tests are now available to quantitatively assess disorders of olfaction. A Brazilian-Portuguese version of the University of Pennsylvania Smell Identification Test (UPSIT) is currently being developed specifically for the Brazilian

Olfactory bulb interneurons releasing NO exhibit the Reelin receptor ApoEr2 and part of those targeted by NO express Reelin

open access: yes, 2008
Nitric oxide (NO) and Reelin both modulate neuronal plasticity in developing and mature synaptic networks. We recently showed a loss of neuronal nitric oxide synthase (nNOS) protein in the olfactory bulb of reeler mutants and advanced the hypothesis that

The Audiologic and Otolaryngologic Phenotype in WHIM Syndrome

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective WHIM syndrome (warts, hypogammaglobulinemia, infections, and myelokathexis syndrome) is an ultra‐rare primary immunodeficiency disease caused by autosomal dominant hyperfunctional mutations in the chemokine receptor CXCR4. Otolaryngologists are frequently consulted to evaluate WHIM patients because of recurrent acute ear and sinus ...
