Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lu...

During development, synaptic exocytosis by cochlear hair cells is first initiated by patterned spontaneous Ca(2+) spikes and, at the onset of hearing, by sound-driven graded depolarizing potentials. The molecular reorganization occurring in the hair cell synaptic machinery during this developmental transition still remains elusive. We characterized the changes in biophysical properties of volta...

The solar erythemal UV irradiances through human hair and the protection from UV provided by human head hair have been investigated for a solar zenith angle (SZA) range of 17-51 degrees for the conditions of a head upright in full sun, a head upright in shade and a head in full sun tilted toward the sun. The two hair lengths investigated were 49.1 +/- 7.1 mm for the short type and 109.5 +/- 5.5...

Abstract The aim of this study was to report patellar groove replacement in a 6-year-old domestic short hair cat with chronic unilateral pelvic limb lameness and severe femoro-patellar osteoarthritis due medial luxation. This is case report. Computed tomographic scan the affected revealed marked periarticular osteophytosis, trochlear ridge erosion, flattening femoral trochlea, ectopic pseudo-tr...

was fluctuating, so evidently contained fluid, and as it had recently become painful, presumably pus. A long incision was made through the tumour, and a large quantity of pus was evacuated, mixed with which was a lot of short hair, like a handful of cropped hair on washing out the cavity, it was found to contain three or four long hairs, whose roots wore firmly fixed to the base of the tumour. ...
