Monoclonal antibody mabQ113 recognizes a 120-kilodalton polypeptide which, in the cerebellar cortex, is confined exclusively to a subset of Purkinje cells which are organized in parasagittal bands (Hawkes et al.: Brain Research 333:359-365, 1985). In all other areas of the adult rat brain examined the localization of the mabQ113 epitope was marked by regional neuronal and glial co-expression (P...

Silk is a key innovation in spiders, fascinating both biologists and material scientists. However, to fulfil their biological function silken threads must be strongly fastened to substrates or other threads. The majority of modern spiders produce a unique and rather unexplored bio-adhesive: the two-compound pyriform secretion, which is spun into elaborate patterns (so called attachment discs) a...

BACKGROUND The aim of this study is to assess the functional and oncologic results of supracricoid hemilaryngopharyngectomy and report our experience in the technique, local control and overall survival rates. MATERIALS AND METHODS 18 selected patients with pyriform sinus cancer treated by supracricoid hemilaryngopharyngectomy in a University Hospital setting. Retrospective chart review was u...

We have constructed models /i/ and /u/ of the vocal tract from the glottis to the velum with the pyriform fossa and the larynx, and have analyzed by finite element method. Sound pressure distributions in XY cross-sections at 500Hz, the first resonant frequencies, and 2500Hz are shown. The barycentric coordinates of real part of the sound intensity and of sound particle velocity in each XY cross...

Background: The inferior turbinate, as part of the nasal valve area, plays a key role in directing the airflow and moisturizing and heating the inspired air. Excessive resection of the inferior turbinate leads to a significant reduction in heating and humidification of inhaled air. Different types of turbinate surgery are described in the current literature. Pyriform Turbinoplasty is a new endo...
