This review is dedicated to self-healing silicone materials, which can partially or entirely restore their original characteristics after mechanical electrical damage caused them, such as formed (micro)cracks, scratches, and cuts. The concept of materials originated from biomaterials (living tissues) capable regeneration functions (plants, human skin bones, etc.). Silicones are ones the most pr...

Immunosuppression is known to be associated with increased rate of malignancies and widespread dermatophytosis in the patients with sezary syndrome and this may account for the occurrence of Kaposi’s sarcoma and generalized dermatophytosis in patients in this report. Herein, we report a 58-year-old farmer man, who admitted with two months history of severely pruritic skin lesions, which p...

The process to be modeled produces micro-hollow particles based on spray drying technology. This process involves droplet formation, solvent(s) evaporation, formation of the impermeable outer layer, and decomposition of the blowing agent. The objective of this work is to develop a fundamental model that describes the formation of the hollow particles starting from a single droplet. This model i...

We describe a palisaded granulomatous skin nodule containing bacterial rods, in a patient with rheumatoid arthritis (RA). The case emphasizes that fact that a known history of RA should not preclude submission of tissue for culture studies or careful histologic review for micro-organisms of any lesion that is interpreted as clinically and/or histologically consistent with a rheumatoid nodule. C...

One motivating application of this technology is the development of a tactile display interface, where discrete mechanical actuators apply vibratory excitation at discrete locations on the skin. Specifically, this paper describes the development fabrication and characterization of a 4 x 4 micro-actuator array of vibrating pixels for fingertip tactile communication. The vibrting pixels are gener...

In awake human subjects, neural responses in cutaneous nerves to electrical stimulation were recorded with intrafascicular tungsten micro-electrodes. Changes in the activity of individual fibre groups during blocking procedures were recorded and correlated with simultaneous alterations in the perception of standardized stimuli. Light touch sensibility in hairy skin was mediated by A-beta-gamma ...

Candida albicans apart from being the most common human fungal pathogen is also the omnipresent component of the mammalian micro biome. In recent years, the incidence of fungal infection has shown a remarkable increase. Candida albicans, is one of the major fungus which is found to be responsible for skin infections (Morrison et al, 2006). Candida albicans exists as a commensal organism in heal...

The outermost layer of the human skin, the stratum corneum (SC), is comprised of structurally inter-positioned anatomical regions. This inter-positioning renders the electrical characterization of its individual region difficult. To address this difficulty, the SC’s electrical properties at the cellular level were investigated. Impedance measurements were performed using a planar microelectrode...
