A 14-year-old West Highland White terrier dog developed multiple raised plaques that were confined to the concave surface of right pinna. Histology allowed a diagnosis viral plaque, although lesions contained some unusual microscopic features. papillomaviral (PV) DNA sequence was amplified from plaque using consensus PCR primers. The used as template design ‘outward facing’ primers, which ampli...

Thresholds were measured at 250, 500, 1,000, 2,000, 3,000, 4,000, 6,000, and 8,000 Hz in 20 normal adult ears and in ten ears from adults with varying amounts of ear-canal collapse. To alleviate the attenuation caused by ear-canal collapse, ear-canal inserts, postauricular pads, or circumaural cushions (Telephonics 510-020) were used with earphones (TDH-49). The circumaural cushions provided th...

Coastal degradation and habitat disruption are severely compromising sessile marine species. The fan shell Pinna nobilis is an endemic, vulnerable species and the largest bivalve in the Mediterranean basin. In spite of species legal protection, fan shell populations are declining. Models analyzed the contributions of environmental (mean depth, wave height, maximum wave height, period of waves w...

Pinna nobilis is an endemic bivalve of the Mediterranean Sea whose populations have decreased in the last decades due to human pressure; as a consequence, it was declared a protected species in 1992. Despite its conservation status, few genetic studies using mitochondrial markers have been published. We report on the isolation and development of 10 microsatellite loci for the fan mussel, Pinna ...

OBJECTIVES Chondrodermatitis nodularis chronica helicis (CNCH) usually presents as a painful nodule affecting the pinna. The aetiology of the disease is unknown. Several theories have been suggested. We suggest a possible explanation based upon pathophysiological treatment correlations to new histopathological evidence. DESIGN A detailed histopathological review of 16 confirmed cases of CNCH ...

The Head Related Transfer Function (HRTF) characterizes the auditory cues created by scattering of sound off a person’s anatomy. While it is known that features in the HRTF can be associated with various phenomena, such as head diffraction, head and torso reflection, knee reflection and pinna resonances and anti resonances, identification of these phenomena are usually qualitative and/or heuris...
