The various types of dysgeusia are discussed and a clinical classification is proposed. Dysgeusia are divided according to the modifications of the intensity of the perception: ipergeusia and ipogeusie/ageusia. The latter are the most frequent and important ones; they are divided in congenital ones, rapidly developing ones, and slow developing ones. A(More)
We consider a diffuse interface model which describes the motion of an incompressible isothermal mixture of two immiscible fluids. This model consists of the Navier-Stokes equations coupled with a convective nonlocal Cahn-Hilliard equation. Several results were already proven by two of the present authors. However, in the two-dimensional case, the(More)
The anatomical basis of taste are discussed both in their peripheral and in central aspects. The perception is based upon four principal flavors; this happens by complex chemical interactions between peripheral receptors of papillae and the taste producing substances. The nervous stimulus flows through fibres of VII-IX-X cranial nerves up to the tractus(More)
We study a non-local variant of a diffuse interface model proposed by Hawkins– Darrud et al. (2012) for tumour growth in the presence of a chemical species acting as nutrient. The system consists of a Cahn–Hilliard equation coupled to a reactiondiffusion equation. For non-degenerate mobilities and smooth potentials, we derive well-posedness results, which(More)
The efficacy and tolerability of the Bacampicillin was evaluated on 80 patients (40 males and 40 females) with infectious pathology. This antibiotic was delivered at different dosage, alone or in association with Fans. The Authors report the statistical results showing the good therapeutical activity, at full dosage, with minor side effects.
The fundamental feature of the bacteriologic flora that causes endodontic lesions is its mixed nature. It has been demonstrated that a mixed flora can more easily give rise to both acute and chronic inflammatory reactions. The coexistence of different families of bacteria within the same environment is based upon a very delicate balance given by the(More)
