Until the late 2010s spiny fan-mussel Pinna rudis shared habitat in many Mediterranean sites with endemic nobilis, which dominated abundance but that has gone locally extinct most of its distribution area due to a recent widespread disease outbreak. In Columbretes Islands Marine Reserve (NW Mediterranean) both species coexisted until 2017, when P. nobilis populations completely disappeared. spr...

background: teat lacerations are serious injuries thatendanger the survival of a cow within the herd. in excessivelacerations, the wound should be left to heal by second intentionhealing process. however, tissue contraction during healing canchange the alignment of the teat, creating problems for machinemilking. objectives: the purpose of the present study was toevaluate the transplantation of ...

dermoid cysts are congenital anomalies derived from ectoderm. they are rare in head and neck region and especially in pinna. we presented an 8-year-old girl with a dermoid cyst in the conchal region of auricle which was treated with complete surgical resection.

Perichondritis is a slow evolving infection, located on the ear cartilage. They result from lacerations, blunt trauma, surgeries and other affections. Ear piercing induced pinna perichondritis is a frequent affection among the young population. The most commonly found etiologic agent is Pseudomonas aeruginosa and its inoculation caused by pinna cartilage and pericondrium exposure during or afte...

On examination, there was no evidence of hoarseness, dyspnoea, photophobia, hearing loss, ataxia and bony deformities. Investigations revealed a mild derangement of liver enzymes, while Rheumatoid factor and CRP were positive. Biopsy of the left ear pinna and leg nodules were done. Histopathology findings were similar from both sites showing a dense lymphoplasmacytic infiltrate, rich in histioc...

Baingio Pinna’s article “New Gestalt principles of perceptual organization: An extension from grouping to shape and meaning” won the 2009 Metzger Award of the Society for Gestalt !eory and its Applications. In this article, Pinna presented a variety of novel images that probe the way in which local and global factors interact to generate the percepts that we consciously see. As Pinna noted at t...

The Pinna illusion (Pinna & Brelstaff, 2000) consists of two concentric rings of micropatterns that appear to counter-rotate when the observer moves towards the stimulus. There have been several reports that the illusion is stronger when the retinal expansion is produced by observer self-motion than when produced on a computer screen without observer self-motion. In fact, we found that the illu...

The watercolor illusion is a long-range color assimilation (coloration effect) imparting a figure-ground segregation (figural effect) across large enclosed areas (B. Pinna, 1987; B. Pinna, G. Brelstaff, & L. Spillmann, 2001; B. Pinna, L. Spillmann, & J. S. Werner, 2003; B. Pinna, J. S. Werner, & L. Spillmann, 2003). The watercolored figure has a very poorly reversible or univocal figure-ground ...
