Little is known about the mechanisms of persistence of obstructive apnea. Structurally, the dorsum of the tongue locates anterior to the soft palate. On the basis of the observation of posterior displacement of the tongue during obstructive apnea, we hypothesized that the dorsum of the tongue pushes the anterior wall of the soft palate posteriorly during inspiratory efforts, maintaining closure...

We propose a general class of five-dimensional soft-wall models with AdS metric near the ultraviolet brane and four-dimensional Poincaré invariance, where the infrared scale is determined dynamically. A large UV/IR hierarchy can be generated without any fine-tuning, thus solving the electroweak/Planck scale hierarchy problem. Generically, the spectrum of fluctuations is discrete with a level sp...

Background: In intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. This study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

Vaginal angiomatosis is regarded as part of a very rare entity of benign vascular tumors of the female genital tract. The incidence of these tumors is extremely low. The rarity of this disease and lack of distinctive features poses a problem of differential diagnosis. We present the case of a 51-year-old female with grade III uterine prolapse and a bleeding vaginal wall mass. Violaceous irregul...

Authors present a rare case of bifocal schwannoma of thoracic wall showing metabolic activity on FDG PET images. A 43-year-old male with palpable mass on lateral chest wall was referred for F-18 FDG PET/CT imaging for differential diagnosis. His medical history and basic laboratory results were unremarkable. PET/CT images revealed a mild FDG uptake in the solid soft tissue mass in the left late...

The procedure is started by performing a total ethmoidectomy (or inferior/subtotal ethmoidectomy) and a wide maxillary antrostomy with standard sinus or powered instrumentation. This is followed by the resection of the entire medial wall of the maxillary sinus (including the inferior turbinate) and the inferior aspect of the middle turbinate. Subsequently, an incision is performed at the level ...

Cleft palate is one of the most common congenital birth defects. Tremendous efforts have been made over the last decades towards understanding hard palate development. However, little is known about soft palate morphogenesis and myogenesis. Finding an appropriate surgical repair to restore physiological functions of the soft palate in patients with cleft palate is a major challenge for surgeons...
