Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

open access: yesAdvanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.

Neuroendocrine adenoma of the middle ear—An intriguing entity

open access: yesClinical Case Reports, 2021
Despite its rarity, the neuroendocrine adenoma of the middle ear (NEAME) is a differential diagnosis of the middle ear disease. We suspect that the NEAME is underdiagnosed and more cases can be detected through education and personal experience ...

Congenital defects of the middle ear-uncommon cause of pediatric hearing loss [PDF]

open access: yes, 2014
INTRODUCTION: In children, hypoacusis, or conductive hearing loss, is usually acquired; otitis media with effusion is the most common etiology. However, in some cases this condition is congenital, ranging from deformities of the external and middle ear
