This paper re-examines the physical basis of frequency analysis and adequate stimulation of the receptors of the locust ear. The anatomy of the locust ear was examined by dissection, serial sections and SEM. The compliance of the tympanum and Muller's organ were measured both with a force transducer and by application of known air pressure. The motion of the tympanum and of Muller's organ excit...

A schwannoma of the larynx is a rare benign tumor that usually presents as a submucosal mass in the pyriform sinus and the aryepiglottic space, and this type of schwannoma constitutes a diagnostic and therapeutic challenge for otolaryngologists. We present here two cases of supraglottic schwannomas that were misdiagnosed as laryngoceles. Both were excised through a lateral thyrotomy approach wi...

Dendritic fibromyxolipoma is a rare and distinctive soft tissue neoplasm that is considered by many authors as a variant of spindle cell lipoma and characterized by the presence of dendritic cytoplasmic processes, plexiform vascular pattern, and keloidal collagen. It has never been reported in the larynx and hypopharynx. Its rarity and the potential to mistake it as a more clinically aggressive...

The pyriform silk of the attachment disc a spider was studied using infrared-visible vibrational sum frequency generation (SFG) spectroscopy. can attach dragline and radial lines to many kinds substrates in nature (concrete, alloy, metal, glass, plant branches, leaves, etc.) with disc. adhesion bear spider's own weight, resist wind on its orb web. From our SFG spectroscopy study, NH group argin...

Branchial cleft cysts are common causes of congenital neck masses in the pediatric population. However, neonatal presentation of branchial cleft cysts is uncommon, but recognizable secondary to acute respiratory distress from airway compression or complications secondary to infection. We report a 1-day-old infant presenting with an air-filled neck mass that enlarged with Valsalva and was not as...
