Middle ear osteoma causing Eustachian tube obstruction: A case report and literature review

Journal of Otology, 2020
Middle ear osteoma is an extremely rare benign tumor of the middle ear. Due to its very slow growth rate and benign nature, osteoma of the middle ear can be found incidentally without causing any symptoms.

Middle ear innovation in Early Cretaceous eutherian mammals

Nature Communications, 2023
The middle ear ossicles in modern mammals are repurposed from postdentary bones in non-mammalian cynodonts. Recent discoveries by palaeontological and embryonic studies have developed different models for the middle ear evolution in mammaliaforms ...

FeDSNP‐Pa Nanoassemblies: A Triple‐Action Therapeutic Strategy Targeting Oxidative Stress, Inflammation, and Pyroptosis for Retinal Ganglion Cell Protection in Glaucoma

Advanced Functional Materials, EarlyView.
FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Steep‐Switching Memory FET for Noise‐Resistant Reservoir Computing System

Advanced Functional Materials, EarlyView.
We demonstrate the steep‐switching memory FET with CuInP2S6/h‐BN/α‐In2Se3 heterostructure for application in noise‐resistant reservoir computing systems. The proposed device achieves steep switching characteristics (SSPGM = 19 mV/dec and SSERS = 23 mV/dec) through stabilization between CuInP2S6 and h‐BN.

Otitis media impacts hundreds of mouse middle and inner ear genes. [PDF]

PLoS ONE, 2013
Otitis media is known to alter expression of cytokine and other genes in the mouse middle ear and inner ear. However, whole mouse genome studies of gene expression in otitis media have not previously been undertaken.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

Advanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...
