Assessing Surgical Extent in Endoscopic Sinus Surgery: A Scoping Review of Scoring Systems

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Endoscopic sinus surgery (ESS) varies substantially in the extent of surgical dissection performed, even when described under the same procedural label. In chronic rhinosinusitis, this heterogeneity may influence postoperative outcomes, revision rates, and response to biologic therapies.

The scent of habitat shift: Olfactory receptor evolution is associated with environmental transitions in turtles

open access: yes
J.G.-P. was supported by the program “Atracción de Talento Investigador Modalidad I” from the Spanish Comunidad de Madrid (reference 2022-T1/AMB-24171). We would like to thank an anonymous reviewer and Quentin Martinez for their helpful comments.

Senescence-like cells recruit γδ T cells to drive prolonged hyposmia after SARS-CoV-2 infection in mice

open access: yesEMBO Reports
Persistent hyposmia is a hallmark of post COVID-19 conditions, yet the mechanisms sustaining olfactory dysfunction after viral clearance remain poorly understood.

Computational modelling of olfactory receptors

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects
Olfactory receptors (ORs), the largest subfamily of G protein-coupled receptors, are essential for detecting and interpreting environmental odorants in animals. Understanding their function is crucial for deciphering olfactory perception and exploring emerging roles in non-olfactory systems. With the recent surge in available sequence data and AI-based

Scalp electroacupuncture targeting trigeminal nerve activation alleviates post‐traumatic stress disorder–induced depression and neuroinflammation in mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Scalp electroacupuncture (SA) through activation of the trigeminal pathway exerts anti‐inflammatory, antidepressant, and anxiolytic effects in an animal model of post‐traumatic stress disorder induced by single prolonged stress. This suggests that SA is involved in neuroinflammation and changes in brain‐derived neurotrophic factor protein through the ...

A study of rat olfactory mechanisms [PDF]

open access: yes
Membranes prepared from the olfactory mucosa of the rat show a high level of adenylate cyclase activity, typically 500 pmol/min/mg protein. The activity increases in the presence of odorants and is inhibited by calcium. Linkage of receptor to cyclase

Differential modulation of feedforward inhibition reflects topographic organization in the olfactory system

open access: yesNature Communications
The nervous system flexibly processes information under different conditions. To do this, neural networks frequently rely on uniform expression of modulatory receptors by distinct classes of neurons to fine tune the computations supported by each ...

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

open access: yesAdvanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...
