certain strains of staphylococcus aureus produce a toxin which cause epidermal exfoliation within 18 hours after direct subcutaneous or intraperitoneal injection into newborn mice. the extracellular product responsible for exfoliation is termed exfoliative toxin (et). in the present studies a modified assay system has been developed for detection of exfoliativeactivity in toxin negative strains...

Since the successful mechanical exfoliation of graphene in 2004, two-dimensional materials have attracted extensive research and development various fields such as electronics, optoelectronics energy, owing to their unique structural physicochemical properties. In terms synthesis methods, researchers made further advancements atomic step method, building upon traditional techniques exfoliation,...

Chemical peeling implies the application of a chemical agent to the skin, which causes controlled destruction of a part or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The present study was directed toward safety concerns associated with superficial chemical peeling with...

The study cohort consists of 459 subjects over 60 years of age. Intraocular pressure and degrees of exfoliation, lens changes, and pigment were recorded and their interrelationships investigated. A raised intraocular pressure was found to be associated with exfoliation, as also was increased pigmentation and the development of lens changes. An original observation is that the exfoliated males h...

In the Eye Outpatient Department of H.P. Medical College Hospital, Simla, nine cases of capsular exfoliation affecting seventeen eyes were seen in the course of 6 months. Their main features are given in Table I (overleaf, pp. I22 and 123). All the patients were males between the ages of 6o and 76 years. The capsular exfoliation was associated with phakodonesis, iridodonesis, glaucoma, primary ...

INTRODUCTION Herpes zoster Infection (HZI) is a viral disease with painful skin rashes and blisters in a limited area on one side of the body, often in a strip. Osteonecrosis with spontaneous exfoliation of teeth in association with HZI of the mandibular nerve is a rare phenomenon. In this report, such an unusual complication of HZI is presented. CASE REPORT The clinical course of a 53-year-o...
