HYPOTHESIS Otosclerosis is related to mild osteogenesis imperfecta with genetic defects in type I collagen. BACKGROUND Otosclerosis is a common bone disease of the human otic capsule that has an underlying hereditary predisposition. The histopathology and clinical manifestations are strikingly similar to the milder forms of osteogenesis imperfecta in(More)
Biofuels derived from non-crop sources, such as microalgae, offer their own advantages and limitations. Despite high growth rates and lipid accumulation, microalgae cultivation still requires more energy than it produces. Furthermore, invading organisms can lower efficiency of algae production. Simple environmental changes might be able to increase algae(More)
A retrospective review of all stapedectomies performed at the Massachusetts Eye and Ear Infirmary over a 13 month period was undertaken to compare the results of argon laser stapedectomy to conventional footplate fenestration techniques. Despite the fact that it was new and unfamiliar to the surgical staff, the complication rate was lower with the argon(More)
Algae biofuel has the potential to replace fossil fuels. However, cultivation and productivity of target algae need improvement, while controlling undesired organisms that can lower the efficiency of production systems. A central composite design and response surface model were utilized to predict cultivation optima of marine microalga, Nannochloropsis(More)
The malleus grip prosthesis is designed for ears with conductive hearing loss caused by pathologic conditions of the stapes in association with pathologic conditions of the malleus or incus. The malleus grip procedure was performed on 220 ears, and follow-up studies are available on 203. Mild to profound sensorineural hearing losses occurred in 16 (8.37%).(More)
We have now performed the cochlear endolymphatic shunt operation for Meniere's disease on 102 ears and have follow-up data on ninety cases. In this fourth report of results of the procedure, we show that after follow-up ranging from one month to six years (average 22.3 months), definitive vertigo was relieved in 72% of the cases and that hearing at the time(More)
