1. Introduction A common topic in recent literature on phonology is the question of whether phonological processes and segments are licensed by prosodic position or by perceptual cues. The former is the traditional view, as represented by e.g. Lombardi (1995) and Beckman (1998), and holds that segments occur in specific prosodic positions such as the coda. In a licensing by cue approach, as rep...

Introduction: The laryngeal mask airway (LMA) is a safe method to establish airway control during general anaesthesia. In otolaryngology surgery, the use of a LMA is well established in ear surgery; however, the use of a LMA during open neck procedures remains controversial. We report a case in which the pharyngeal distortion by the LMA cuff resulted in an iatrogenic complication.   Case Report...

We report a case of mediastinal and bilateral retro-orbital emphysema following an uncomplicated endoscopic sphincterotomy. The concurrent presence of these complications following endoscopic retrograde cholangiopancreatography is rare. The simultaneous occurrence of these two complications in the same patient has not been previously reported in the literature. Furthermore, we define the first ...

In Caenorhabditis elegans, five pharyngeal gland cells reside in the terminal bulb of the pharynx and extend anterior processes to five contact points in the pharyngeal lumen. Pharyngeal gland cells secrete mucin-like proteins thought to facilitate digestion, hatching, molting and assembly of the surface coat of the cuticle, but supporting evidence has been sparse. Here we show pharyngeal gland...

ABSTRACT Modulating retro-reflectors provide a means for free space optical communication without the need for a laser, telescope or pointer tracker on one end of the link. These systems work by coupling a retro-reflector with an electro-optic shutter. The modulating retro-reflector is then interrogated by a cw laser beam from a conventional optical communications system and returns a modulated...

Despite the fact that common surgical techniques for the treatment of genu varum usually correct the malalignment in the affected knee, these methods have significant complications and cause problems in the long term. Retro-tubercle opening-wedge high tibial osteotomy is among the newer techniques for the treatment of genu varum. The goal of this study was to compare the results of retro-tuberc...

BACKGROUND Walking, a closed kinetic chain (CKC) activity, is widely used in knee rehabilitation as it allows early weight bearing and movement. It has been suggested that retro-walking may provide additional benefits beyond those experienced by forward-walking. The present study will investigate the effect of retro- and forward-walking on quadriceps muscle strength, pain, function, balance and...

Retro-translocation from the ER to the cytosol of proteins within the secretory pathway takes place on misfolded molecules that are targeted for degradation by the cytosolically located 26S proteasome complex. Retro-translocation occurs also for other proteins (such as calreticulin) that, despite being synthesized and transported to the ER, are in part dislocated to the cytosol. We have taken a...

This paper applies acoustic principles and a novel scanning method motivated by acoustic flow to recognize retro-reflectors directly from sonar echoes while performing drive-by scanning. Right-angle corners and cylinders form specular retro-reflectors that produce strong echoes whose features can be easily identified. A multi-point sonar produces a point process whose density encodes the echo a...

BACKGROUND Although a potentially important route for transmission, limited data exist on the burden of pharyngeal chlamydia (CT) and gonorrhea (GC) among men who have sex with men (MSM). We examined pharyngeal CT and GC among MSM screened in San Francisco in 2010. METHODS MSM seeking services in a variety of clinical settings provided clinician-collected pharyngeal specimens that were tested...
