Circumscribed juvenile pityriasis rubra pilaris (PRP) is a form of PRP that manifests with well-defined erythematous scaly plaques with follicular keratosis mainly over knees and elbows. There are several reports of the association of PRP with other conditions. We report a boy with scattered erythematosquamous skin lesions and follicular hyperkeratotic papules since the age of six years. ...

We have investigated the vibrational relaxation of a bare C60 fullerene and C60 fullerenes with covalently attached poly ethylene oxide PEO chains in aqueous solution using classical molecular dynamics simulations. The rate of transfer of vibrational energy from the excited fullerene to the surrounding water was found to be slow for the bare fullerene, with a vibrational relaxation time of appr...
