Deciphering Auditory Hyperexcitability in Otogl Mutant Mice Unravels an Auditory Neuropathy Mechanism

Advanced Science, EarlyView.
By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Stochastic approach for elliptic problems in perforated domains [PDF]

arXiv
A wide range of applications in science and engineering involve a PDE model in a domain with perforations, such as perforated metals or air filters. Solving such perforated domain problems suffers from computational challenges related to resolving the scale imposed by the geometries of perforations.

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Endoscopic ultrasound and hisopathologic correlates in eosinophilic gastroenteritis

The Saudi Journal of Gastroenterology, 2007
Eosinophilic gastroenteritis is a rare condition characterized by eosinophilic infiltration into any layer of stomach and intestine (mucosa, muscularis mucosa and serosa), usually in association with peripheral eosinophilia.

Thermal effect in laser perforation of liver

Journal of Biomedical Photonics & Engineering, 2018
One of the trends in the development of modern regeneration medicine is the application of high-intensity laser radiation for deep perforation of biological tissues, stimulating the regeneration of structure and functions of the pathologically changed ...

Comparison Between Damping Coefficients of Measured Perforated Micromechanical Test Structures and Compact Models [PDF]

Dans Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS - DTIP 2008, Nice : France (2008), 2008
Measured damping coefficients of six different perforated micromechanical test structures are compared with damping coefficients given by published compact models. The motion of the perforated plates is almost translational, the surface shape is rectangular, and the perforation is uniform validating the assumptions made for compact models.

Ultra‐low LOD H2O2 Sensor Based on Synergistic Nernst Potential Effect

Advanced Science, EarlyView.
Due to the synergistic effect of ENernst,H2O2${E}_{\mathrm{Nernst},\ {\mathrm{H}}_{2}{\mathrm{O}}_{2}}$ and ENernst,H+${E}_{\mathrm{Nernst},\ {\mathrm{H}}^{+}}$, the proposed sensors in this study can achieve ultralow H2O2 detection limit as low as 1.8 × 10−12 M based on the stacked PEDOT: BTB/PEDOT: PSS semiconducting layer.

The Subtle Journey of a Right Atrial Lead

JACC: Case Reports, 2020
We report an unusual case of subacute right atrial perforation by a screw-in pacemaker lead that migrated into the right lung causing hemopneumothorax 2 weeks after the procedure. After transvenous simple manual traction and minithoracotomy repair of the

Concentration of eigenfunctions of a locally periodic elliptic operator with large potential in a perforated cylinder [PDF]

arXiv, 2014
We consider the homogenization of an elliptic spectral problem with a large potential stated in a thin cylinder with a locally periodic perforation. The size of the perforation gradually varies from point to point. We impose homogeneous Neumann boundary conditions on the boundary of perforation and on the lateral boundary of the cylinder.
