The homotopic and heterotopic callosal connections in the forelimb representations of the second (SII) and fourth (SIV) somatic sensory areas of cats were investigated by means of the axonal transport of horseradish peroxidase (HRP) in conjunction with microelectrode recording. The tracer was injected in the electrophysiologically identified hand and/or(More)
BACKGROUND The arterial vascular supply of maxillary sinus has to be considered in all the surgical procedures where it is involved. In particular, the intraosseous anastomosis between the posterior superior alveolar artery and the infraorbital artery branches in the bony canal can be tricky to a not well aware clinician. The aim of this study is to(More)
Anatomical and electrophysiological experiments were performed on cats to investigate the pattern of divergence and convergence in the association projections from the first (SI) to the second (SII) somatic sensory cortex and to ascertain whether diverging and converging fibre components from SI have receptive fields (RFs) matching those of target neurons(More)
PURPOSE The aim of the present in vitro study was to evaluate the leakage observed for 2 different microbial species at the level of the implant-abutment (I-A) interface, and the marginal fit and size of microgap at the I-A interface in 2 different implant connections. METHODS Ten specimens of each group were tested. The inner parts of 5 implants per(More)
In descriptions of surgical procedures in mandible, often there is no mention of an anatomical variance, the genial spinal foramina, where nerves and vessels go through. Aim of this study is to investigate frequency, shape, and dimensions of these foramina. 56 computed tomography dentascans were analyzed with an implant planning software. The considered(More)
Lingual mandibular foramina are peculiar anatomical variations often present on the bone surface of the inferior jaw. These structures host vascular and nervous anastomosis deriving from the branches of the submental artery, lingual artery, and the mylohyoid nerve. Reports pointed out intra-operative massive bleeding accidents during implant interventions(More)
In recent years the spread of the ectoparasitic mite Varroa destructor has become the most serious threat to worldwide apiculture. In the model presented here we extend the bee population dynamics with mite viral epidemiology examined in an earlier paper by allowing a bee-dependent mite population size. The results of the analysis match field observations(More)
Aim of this study was to investigate the gross anatomy of the root of European anterior teeth. A review of the dental literature shows that in the past the root morphology was investigated from the inner pulp chamber for endodontic therapies. In order to be admitted to the study, the teeth had to be undamaged. Each tooth was identified by a serial number(More)
This paper proposes a new automatic approach to determine the accurate measure of human teeth. The aim of the proposed computer based method is to reduce inaccuracy of measurement with respect to traditional approaches. Starting from a 3D model of the teeth which is obtained from 3D scanning, the method algorithmically evaluates the most important(More)
The ectoparasitic mite Varroa destructor has become one of the major worldwide threats for apiculture. Varroa destructor attacks the honey bee Apis mellifera weakening its host by sucking hemolymph. However, the damage to bee colonies is not strictly related to the parasitic action of the mite but it derives, above all, from its action as vector increasing(More)
