Diagnostic performance of corneal epithelium- and Bowman's layer thickness mapping in patients with unilateral Keratoconus.
Graefes Arch Clin Exp Ophthalmol
January 2025
Department of Ophthalmology and Optometry, Medical University of Vienna, Vienna, Austria.
Purpose: To investigate the role of corneal epithelium- and Bowman's layer-thickness (ET and BLT) changes as possible early biomarkers of keratoconus (KC) development.
Methods: In this cross-sectional study patients with unilateral KC (UKC) and a group of healthy controls underwent polarization sensitive optical coherence tomography (PS-OCT) for the evaluation of corneal ET and BLT. These values were compared among three subgroups of eyes, i.
Glia control experience-dependent plasticity in an olfactory critical period.

Sensory experience during developmental critical periods has lifelong consequences for circuit function and behavior, but the molecular and cellular mechanisms through which experience causes these changes are not well understood. The antennal lobe houses synapses between olfactory sensory neurons (OSNs) and downstream projection neurons (PNs) in stereotyped glomeruli. Many glomeruli exhibit structural plasticity in response to early-life odor exposure, indicating a general sensitivity of the fly olfactory circuitry to early sensory experience.

Background: Pregnancy leads to physiological changes primarily driven by hormones like oestrogen and progesterone. Such changes are multi-systemic in nature including involvement of the ear, nose and throat. Such changes impair the quality of the life of pregnant women and thus requires prompt intervention during pregnancy.

College of Life Sciences, Linyi University, Linyi 276000, China.
Wasabi is a type of sauce made from the plant horseradish. During its production and storage, gas production sometimes occurs, which leads to changes in the flavor quality of wasabi. In this study, an electronic nose, electronic tongue, headspace-gas chromatography-mass spectrometry and headspace-gas chromatography-ion mobility spectrometry combined with multivariate statistical analysis were used to compare the differences in odor, taste and volatile components between normal and gas-producing wasabi.

Ear, Nose and Throat, James Cook University Hospital, Middlesbrough, UK.
A male infant presented with reduced oral intake, low-grade fever and postauricular erythema. Clinical examination revealed a soft, tender swelling posteroinferior to the mastoid tip with a dull tympanic membrane on otoscopy. Cross-sectional imaging did not show any evidence of middle ear infection or mastoiditis.
