A case of dermatophytic pseudomycetoma, in a patient with a history of recurrent lesions in the scalp, for over two years, is reported. Histopathological examination of the affected tissues revealed the mycelial aggregates or pseudogranules characteristic of the disease. Cultures of fresh tissues samples detected a fungus identified as Trichophyton tonsurans. Additional examinations failed to d...

Onychomycosis is a fungal infection of nail, its matrix, and other nail parts which is usually caused by dermatophytes.

In this paper, the causes of the crack initiation in cast iron bullion moulds in Meybod Steel Corporation are investigated and then some new geometrical models are presented to replace the current moulds. Finally, among the new presented models and according to the life assessment, the best model is selected and suggested as the replaced one. For this purpose, the three recommended moulds were ...

Dermatophytes are keratinophilic fungi that can be pathogenic for humans and animals by infecting the stratum corneum, nails, claws or hair. The first infection step consists of adherence of arthroconidia to the stratum corneum. The mechanisms and the kinetics of adherence have been investigated using different in vitro and ex vivo experimental models, most notably showing the role of a secrete...
