Recurrent ossifying fibroma of the maxillary sinus in an adult patient.

2013

In some aspects, the terminology of fibro-osseous lesions of the head remain equivocal. The WHO classification suggested to group cemento-ossifying fibroma and ossifying fibroma under the term "ossifying fibroma". Based on the different age of onset, localization and risk of recurrence, two types have been described: "juvenile ossifying fibroma", with early age of onset, which needs to be treated with wide surgical resection due to the high risk of recurrence; and "adult ossifying fibroma", arising in adult patients, with low recurrence rate, properly treated by conservative surgery. We describe a case of an "adult ossifying fibroma" of a 57-yearold woman with several relapses, for whom con…

Mucosal Neuroma Syndrome without mutations of the RET-protooncogene: A histologic study on a case, supported by molecular genetic analysis.

2010

Mucosal neuromas are nerve hamartomas of the digestive tract and larynx, usually observed in the setting of Multiple Endocrine Neoplasia type 2B (MEN2B), i.e. in the presence of typical mutations and in association with medullary thyroid carcinoma, pheochromocytoma and marfanoid habitus. Exceptionally, they arise without the accompanying mutations and endocrine tumors, and in this paper we are reporting a histologic study on a case lacking the specific mutations. The patient was an adolescent girl with marfanoid habitus, with a left-sided epidermal nevus of the neck, and a bulging left upper lip and cheek. The left side of her tongue was considerably enlarged and studded with multiple protr…

Dimensione frattale in biologia ed in medicina umana.

2009

Nell’organismo umano, esistono fattori che contribuiscono a rendere stabili i suoi sistemi frattali biologici. Nel presente lavoro di anatomia comparata e di fisiologia, illustro alcuni di questi sistemi ad invarianza di scala; descrivo le principali forze che li determinano, li regolano e stabilizzano. Riporto altresì alcune patologie, collegate alle alterazioni della (FD) dimensione frattale. La ricca bibliografia consultata mi ha dato modo di tracciare importanti correlazioni come quello tra due dimensioni frattali: del sistema nervoso centrale e della circolazione sanguigna cerebrale.

Nel tentativo di fornire spiegazioni esaurienti sul fenomeno della mente umana, il presente saggio scientifico di anatomia comparata e di fisiologia considera alcune tesi di fondo che si collegano a nuovi parametri fisici della realtà che ci circonda.

A METHOD FOR STUDYING GENETICS OF THE PREDATORY MITE PHYTOSEIULUS PERSIMILIS

2008

Two DNA extraction and purification procedures for single mite analysis, organic (phenol-chloroform) method and the Chelex® -100 DNA extraction procedure, have been compared concerning extraction efficiency, DNA purity and DNA suitability for amplification. Phenol-chloroform extraction takes a relatively long period of time (5 days) and involves the use of toxic and hazardous chemical reagents but it produces consistent results. Chelex is a chelating resin that has a high affinity for polyvalent metal ions, Singer-Sam et al. postulated that boiling a sample in the presence of chelex prevents the degradation of DNA. Both method were evaluated to extract DNA from single frozen mite or individ…
