externa: preliminary result

Otomycosis is a fungal infection of the ear predominantly caused by Candida and Aspergillus spp. The possible virulence factors of Candida spp. are enzymes, such as proteases, phospholipases, phosphatases and esterase. According to our knowledge, protease production in Candida strains isolated from patients with otomycosis has not been investigated. The present study was aimed at determining in vitro protease activity in 8 strains of Candida spp. (C. parapsilosis, C. famata, C. guilliermondii and C. albicans) isolated from children with otomycosis. A majority of isolated strains 7/8 (87.5%) were protease positive. The protease activity ranged from Pz 0.61 to 0.78. Further investigation is necessary to clarify the contribution of protease production to Candida virulenc

Classical Mechanics of Two-Electron Atoms

We study the classical electron motion of two- electron atoms. We present techniques to regularize singularities in the equations of motion and to calculate stability properties of periodic orbits in six-dimensional phase space. Depending on the configuration of the electron pair the classical phase space turns to be regular, purely chaotic, or of mixed structure. For the fully hyperbolic case of collinear electron motion a strong correlation between ionizing trajectories and the collision manifold of the triple collision is found. For the near- integrable collinear motion with both electrons on the same side of the atom we (numerically) derive an action-angle representation of the Hamiltonian
